Description

[Technical Field]

[0001] The present invention relates to a disaster prevention system that automatically inspects an operating device equipped with a switch for a disaster prevention device connected to a disaster prevention receiving panel, and to an operating device that can be automatically inspected. [Background technology]

[0002] Disaster prevention devices equipped with disaster prevention equipment for use in emergencies such as fires and the like have been known, and are installed in tunnels on expressways, motorways, and the like. Examples of such disaster prevention devices include fire hydrant devices and reporting devices. For example, a fire hydrant device includes a fire hydrant storage compartment with a hydrant door that can be opened and closed to store fire hydrant equipment such as hoses with nozzles attached and valves, a fire extinguisher storage compartment with a fire extinguisher door that can be opened and closed to store fire extinguishers, and an electrical door adjacent to the fire extinguisher door that is equipped with a red indicator light, a transmitter, a response lamp, etc. on its front side and with electrical equipment such as a telephone jack on its back side. The fire hydrant storage compartment also includes a water hydrant for use by firefighters, and a pump starter device is located near the hydrant.

[0003] Here, the transmitter is equipped with a push-button switch for transmitting a fire alarm signal, and the push-button that serves as the switch's operating part is arranged so that it can be pressed from the front side through a designated opening in the electrical door, and a protective plate (safector) made of a transparent organic glass plate or the like is held removably on the front side of the opening in the electrical door (Patent Document 1).

[0004] In the event of an emergency such as a fire resulting from a vehicle accident, if a road user presses the protective plate of the transmitter firmly from the front, the push button is pressed through the protective plate, pressing and activating the switch, and a fire notification signal (transmission signal) is sent from the transmitter to a disaster prevention receiving panel in an electrical room, etc., which then outputs a fire alarm, and an accompanying response signal is sent from the disaster prevention receiving panel to the fire hydrant device, causing the response lamp to light up.

[0005] With such conventional transmitters, regular inspections are performed by visiting the site and operating the transmitter to confirm that it is functioning properly. If the same operations as in an emergency are performed during the inspection of this transmitter, it is necessary to reinsert the protective plate into the opening and return it to its original state after the inspection is completed. For example, in Patent Document 1, when the protective plate is pushed in, it falls into the space between the front panel of the electrical door and the push button, and the operation of returning the protective plate to the opening requires a special tool, which is time-consuming and labor-intensive. Furthermore, if the protective plate is a destructive seal, it is necessary to replace the protective plate with a new one after the inspection is completed, which is also time-consuming and labor-intensive.

[0006] To solve this problem, Patent Document 2 discloses a door structure with an outer door and an inner side, with a protective plate on the outer door side and a switch on the inner door, with the push button of the switch located on the front side of the inner door, as shown in Figures 1, 2, and 4. When inspecting the transmitter, only the outer door is opened, making it possible to press the push button without pressing the protective plate, i.e., while the protective plate is held in the opening, thereby facilitating the inspection of the transmitter and improving the efficiency of the inspection work.

[0008] However, conventional transmitter inspections require on-site visits to the site where the fire hydrants are installed. In sites with many fire hydrants and a wide installation area, such as long tunnels, simply visiting all the hydrants requires considerable time and effort, leaving room for improvement in inspection efficiency. Furthermore, regular inspections are typically conducted twice a year, meaning that even if a transmitter malfunctions during operation, the malfunction may be left unaddressed depending on the timing of the inspection, potentially resulting in insufficient transmitter reliability. Furthermore, in tunnels currently in use, maintenance personnel must enter the tunnel while there are many vehicles traveling through it, posing safety hazards. In some cases, road closures and lane restrictions may be necessary, resulting in economical costs.

[0009] Furthermore, this problem is not limited to transmitters, but also applies to operating devices installed in disaster prevention devices that also have switches, such as pump start-up devices installed in fire hydrant devices.

[0010] The present invention aims to provide a disaster prevention system and an operating device that can be automatically inspected, which can improve the inspection efficiency and reliability of operating devices such as transmitters and pump start-up devices installed in disaster prevention devices such as fire hydrant devices.

[0024] (Automatically inspectable operating device) The present invention also provides an operating device that operates a switch by a pressing operation to transmit a predetermined signal, It is characterized by having an inspection structure that activates a switch upon receiving an instruction for inspection operation from outside.

[0025] Furthermore, the other features of the operating device are similar to those of the operating device in the disaster prevention system described above, and therefore their description will be omitted. [Effects of the Invention]

[0026] (Effectiveness of disaster prevention systems) The present invention is a disaster prevention system in which a predetermined number of disaster prevention devices, each equipped with an operating device that activates a switch when pressed to transmit a predetermined signal, are connected to a disaster prevention receiving panel, and the disaster prevention receiving panel is equipped with an inspection control unit that instructs the inspection operation of the switch of the operating device installed in the disaster prevention device, and the operating device is equipped with an inspection structure that activates the switch when it receives an inspection operation instruction from the inspection control unit of the disaster prevention receiving panel.Therefore, without the need for workers to go to the site, such as inside a tunnel where the disaster prevention device is installed, inspection of the operating device is automatically performed based on inspection instructions from the disaster prevention receiving panel installed in an electrical room, etc., and the status of the operating device can be confirmed by whether or not the signal is received by the disaster prevention receiving panel, making it possible to inspect the operating device easily and efficiently.

[0027] In addition, since the operating device is automatically inspected remotely in response to inspection instructions from the disaster prevention receiving panel, there is no restriction on the timing of inspection as with conventional periodic inspections, and it is possible to inspect at any time and shorten the inspection cycle, thereby improving the reliability of the operating device.

[0028] (Effect of inspection structure of operating device) In addition, the inspection structure of the operating device comprises a case body which is a predetermined cylindrical body and is operated from one end and has a switch located inside the other end; a pressing operation unit which is movable toward one end inside the case body and is stored in an initial position so that it can be pressed from the outside of one end side of the case body; an inspection drive unit which is stored in the case body and continues from the pressing operation unit toward the other end so that it can be moved freely, and which pushes the drive shaft toward the other end side of the case body when electricity is applied; and a spring member which is stored in the case body and continues from the inspection drive unit toward the other end side, and which holds the inspection drive unit and the pressing operation unit in their initial positions.The switch is designed to be activated by pressure from the drive shaft when the pressing operation unit is pressed to move the inspection drive unit against the spring member, and by pressure caused by the drive shaft being pushed out when electricity is applied to the inspection drive unit, so that the switch can be activated both by a pressing operation by a person in an emergency and by pressure due to an inspection instruction from a disaster prevention receiving panel. In addition, although the function and structure for automatic inspection have been added, this does not affect the ability of people to press the button in an emergency, and road users can operate it in the same way as conventional disaster prevention devices.

[0029] (Effect of inspection structure of non-locking switch) Furthermore, if the switch is a non-locking switch, the inspection structure for the operating device further includes a rotational holding mechanism that, when the pressing operation unit is pressed while the switch is in its initial position, rotates the inspection drive unit and moves it toward the other end, holding it in a predetermined position where the contacts of the non-locking switch are closed. When the pressing operation unit is pressed while the inspection drive unit is held in the predetermined position, the rotational holding mechanism releases the inspection drive unit and rotates it to its initial position, opening the contacts of the non-locking switch. This allows the contacts of the non-locking switch to remain closed even when the pressing operation by a person in an emergency is released, allowing the non-locking switch to continue transmitting signals to the disaster prevention receiving panel in an emergency. Furthermore, during recovery after a fire has been extinguished, the pressing operation unit can be pressed again to release the inspection drive unit and return it to its initial position, stopping the signal again.

[0030] (Effect of rotation holding mechanism) The rotation holding mechanism includes a rotation guide groove formed on the outer periphery of the case body at a predetermined inclination angle with respect to the axial direction which is the movement direction of the inspection drive unit, a guide pin that stands on the outer periphery of the inspection drive unit in accordance with the position of the rotation guide groove and moves along the rotation guide groove to rotate the inspection drive unit in the axial direction, a lock pin that stands on the outer periphery of the drive shaft of the inspection drive unit, an inclined guide surface that is formed on the outer periphery of the case body and guides and moves the lock pin in the direction of the predetermined inclination angle as the inspection drive unit rotates and moves, and locks the lock pin at a predetermined position that closes the contacts of the non-lock switch, and the axial movement of the drive shaft when current is applied to the inspection drive unit. and a guide opening provided with a linear guide surface that guides and moves the lock pin in the axial direction when the lock pin moves in the axial direction, and the spring member imparts a rotational restoring force to the inspection drive unit that is held by the engagement of the lock pin on the inclined guide surface of the guide opening, and when the lock pin is released as a result of pressing the pressing operation unit, the rotational restoring force moves the inspection drive unit to its initial position.Therefore, during automatic inspection, the lock pin that stands on the drive shaft of the inspection drive unit is moved along the linear guide surface of the guide opening formed on the outer periphery of the case body, thereby moving the drive shaft and enabling the drive shaft to close the contacts of the non-lock switch.

[0031] On the other hand, when a person presses the button in an emergency, the guide pin standing on the outer periphery of the inspection drive unit is rotated along the rotary guide groove formed on the outer periphery of the case body, and the lock pin standing on the drive shaft of the inspection drive unit is rotated along the inclined guide surface of the guide opening formed on the outer periphery of the case body, thereby rotating the inspection drive unit and allowing the drive shaft to close the contacts of the non-lock switch and to lock the lock pin at a position where the contacts of the non-lock switch are closed.

[0032] In addition, when the inspection drive unit is rotated, a rotational restoring force is applied to the inspection drive unit, which is held in place by the lock pin engagement via the spring member.Therefore, when the pressing operation unit is pressed again after the fire has been extinguished and recovery is being performed, the rotational restoring force of the spring member pushes the inspection drive unit back to its initial position, making it possible to open the non-lock switch.

[0033] (Lock switch inspection structure and effect of guide mechanism) Furthermore, when the switch is a lock switch, the inspection structure for the operating device further includes a guide mechanism that, when the pressing operation unit is pressed, moves the inspection drive unit toward the other end and switches the contact state of the lock switch to hold it closed or open, and as a case mechanism, includes a linear guide groove formed in the axial direction which is the movement direction of the inspection drive unit on the outer periphery of the case body, and a guide pin that stands on the outer periphery of the inspection drive unit in accordance with the position of the linear guide groove and moves along the linear guide groove to move the inspection drive unit in the axial direction.This makes it possible to switch the contact state of the lock switch by pressing it in an emergency, and a signal is continuously sent to the disaster prevention receiving panel in an emergency, and when recovery is underway after a fire has been extinguished, the pressing operation unit can be operated again to switch the contact state of the lock switch again and stop the signal.

[0034] (Effect of automatic inspection using P-type transmission for operating devices equipped with non-locking switches) Further, a plurality of disaster prevention devices are connected to a signal wiring drawn out from the disaster prevention receiving panel, and the signal wiring includes an operation wiring to which a non-lock switch of the operation device is branched and an inspection control wiring to which an inspection drive unit of the operation device and an inspection circuit unit that controls the inspection operation are branched and connected, the inspection circuit unit having a delayed opening switch that opens a contact point after a predetermined time from energization and a delayed closing switch that closes a contact point after a predetermined time from energization, the delayed opening switch is branched and connected to the inspection control wiring so as to be in series with the inspection drive unit, the delayed closing switch is inserted and connected to the inspection control wiring that connects the disaster prevention devices, and the inspection control unit of the disaster prevention receiving panel issues a predetermined control signal to the inspection control wiring as an instruction for the inspection operation. When a predetermined control power is supplied via the inspection control wiring, the disaster prevention device closes the contacts of the non-lock switch by energizing the inspection drive unit, the operating device sends a predetermined signal via the operating wiring to the disaster prevention receiving panel, and when a predetermined time has passed since energizing the inspection circuit unit, the delay-opening switch opens to stop energization of the inspection drive unit and open the contacts of the non-lock switch, the operating device stops sending the predetermined signal, and the delay-closing switch opens to supply the predetermined control power to the next-stage disaster prevention device via the inspection control wiring, making it possible to automatically inspect the operating devices of multiple disaster prevention devices connected to one signal wiring in sequence. Also, because control power is supplied to the next-stage disaster prevention device only after inspection of the operating device is completed, automatic inspections of multiple disaster prevention devices are not performed simultaneously, making it possible to reliably inspect all operating devices.

[0035] (Effect of the time-delay relay that constitutes the inspection circuit section) Furthermore, the inspection circuit section is a time-limit relay that activates the contacts a predetermined time after energization, the delayed normally-open switch is a time-limit normally-closed contact of the time-limit relay that opens a predetermined time after energization, and the delayed closing switch is a time-limit normally-open contact of the time-limit relay that closes a predetermined time after energization, so by using a time-limit relay that has a time-limit normally-closed contact and a time-limit normally-open contact, it is possible to easily set up the inspection circuit section.

[0036] (Effect of automatic inspection using P-type transmission for operating devices equipped with lock switches) Further, a plurality of disaster prevention devices are connected to signal wiring drawn out from the disaster prevention receiving panel, and the signal wiring includes an operation wiring to which a lock switch of the operation device is branched and an inspection control wiring to which an inspection circuit unit that controls an inspection drive unit and inspection operation of the operation device is branched and connected, the inspection circuit unit outputs a first control signal twice with a predetermined interval between them when power is received from the inspection control wiring, and subsequently outputs a second control signal with a predetermined interval between the second output of the first control signal, and is provided with an inspection drive switch that closes a contact by the first control signal and a transfer switch that opens a contact by the second control signal, the inspection drive switch is branched and connected to the inspection control wiring so as to be in series with the inspection drive unit, and the transfer switch is inserted and connected to the inspection control wiring that connects the disaster prevention devices, the inspection control unit of the disaster prevention receiving panel supplies a predetermined control power source to the inspection control wiring as an instruction for an inspection operation, and the disaster prevention devices are connected to a predetermined control power source by the inspection control wiring. When control power is supplied, the inspection circuit unit outputs a first first control signal to close the inspection drive switch and energize the inspection drive unit, the inspection drive unit closes the contacts of the lock switch, the operation device transmits a predetermined signal to the disaster prevention receiving panel via the operation wiring, and when a predetermined time has elapsed since the output of the first first control signal, the inspection circuit unit outputs a second first control signal to close the inspection drive switch and energize the inspection drive unit, the inspection drive unit opens the contacts of the lock switch that have been held closed, the operation device stops transmitting the predetermined signal, and when a predetermined time has elapsed since the output of the second second control signal, the inspection circuit unit outputs a second control signal to close the transfer switch and supply the predetermined control power to the next-stage disaster prevention device via the inspection control wiring, it is possible to automatically inspect the operation devices provided in multiple disaster prevention devices connected to one signal wiring in the same way as a non-locking switch. In addition, since the control power is supplied to the next stage disaster prevention device after the inspection of the operating device is completed, automatic inspection is not performed on multiple disaster prevention devices at the same time, making it possible to reliably inspect all operating devices.

[0037] (Effect of automatic inspection by R-type transmission of operating device equipped with non-locking switch) Further, a plurality of disaster prevention devices are connected to signal wiring drawn out from the disaster prevention receiving panel, and the signal wiring includes an operation wiring to which a non-lock switch of the operation device is branched and a transmission wiring also serving as a power source to which a transmission control unit for controlling an inspection drive unit of the operation device and inspection operation and signal transmission with the disaster prevention receiving panel is branched and connected, the transmission control unit having a unique address set therein, and outputs a control signal for a predetermined time based on an inspection instruction signal that matches its own address received from the inspection control unit of the disaster prevention receiving panel via the transmission wiring also serving as a power source, and is provided with an inspection drive switch that closes a contact point by the control signal, and the inspection drive switch is branched to the transmission wiring also serving as a power source so as to be in series with the inspection drive unit. The disaster prevention receiving panel is connected via a branch connection, and the inspection control unit of the disaster prevention receiving panel transmits an inspection instruction signal with a specified address specified to the power supply / signal wiring as an instruction to perform an inspection operation. When the transmission control unit of the disaster prevention device receives an inspection instruction signal that matches its own address, the transmission control unit outputs a control signal for a specified period of time to close the inspection drive switch for a specified period of time to energize the inspection drive unit, the inspection drive unit closes the contacts of the non-lock switch for a specified period of time, and the operating device transmits a specified signal to the disaster prevention receiving panel via the operating wiring for a specified period of time, so that it is possible to arbitrarily specify and inspect the disaster prevention device to be inspected using the inspection instruction signal with a specified address, enabling flexible automatic inspection.

[0038] (Effect of automatic inspection by R-type transmission of operating device equipped with lock switch) Further, a plurality of disaster prevention devices are connected to signal wiring drawn out from the disaster prevention receiving panel, and the signal wiring includes an operation wiring to which a lock switch of the operation device is branched and a transmission wiring that also serves as a power source to which an inspection drive unit of the operation device and a transmission control unit that controls the inspection operation and signal transmission with the disaster prevention receiving panel are branched and connected, the transmission control unit is set with a unique address, and outputs a control signal twice for a predetermined time based on an inspection instruction signal that matches its own address received from the inspection control unit of the disaster prevention receiving panel via the transmission wiring that also serves as a power source, and is provided with an inspection drive switch that closes a contact by the control signal, the inspection drive switch is branched and connected to the transmission wiring that also serves as a power source so as to be in series with the inspection drive unit, and the inspection control unit of the disaster prevention receiving panel transmits an inspection instruction signal with a specified address specified to the signal wiring that also serves as a power source as an instruction for the inspection operation, When the transmission control unit of the device receives an inspection instruction signal that matches its own address, the transmission control unit outputs a first control signal for a predetermined period of time to close the inspection drive switch for a predetermined period of time, thereby energizing the inspection drive unit, the inspection drive unit closes the contacts of the lock switch, and the operation device sends a predetermined signal to the disaster prevention receiving panel via the operation wiring, and when a predetermined time has passed since the output of the first control signal, the transmission control unit outputs a second control signal for a predetermined period of time to close the inspection drive switch for a predetermined period of time, thereby energizing the inspection drive unit, the inspection drive unit opens the contacts of the lock switch that are held closed, and the operation device stops sending the predetermined signal.As a result, just like a non-lock switch, it is possible to arbitrarily specify the disaster prevention device to be inspected using an inspection instruction signal with a specified address, allowing for flexible inspections.

[0039] (Effect of inspection drive unit using linear motor) The inspection drive unit is a linear motor made of a magnetic material and equipped with a cylindrical yoke with an E-shaped cross section in the axial direction, which is the direction of movement of the inspection drive unit, and a moving coil arranged in the yoke so that a bobbin wound with a coil can be moved in the axial direction. The drive shaft is arranged on the end face on the other end of the moving coil, so that when current is applied to the moving coil of the linear motor during automatic inspection, electromagnetic induction moves the moving coil toward the other end relative to the yoke, making it possible to reliably close the switch contacts by pushing in the drive shaft. The linear motor is also small, for example, with a diameter of about 30 mm and a length of 25 mm, and can be easily incorporated into transmitters and pump start-up devices.

[0040] Furthermore, the invention relating to the operating device has the same effects as those of the operating device in the disaster prevention system described above, and therefore a description thereof will be omitted. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0042] [Basic concept of the embodiment] First, the basic concept of the embodiment will be described. The embodiment generally relates to a disaster prevention system in which a predetermined number of disaster prevention devices, each equipped with an operating device that activates a switch by pressing it and transmits a predetermined signal, are connected to a disaster prevention receiving panel, and the scope of the invention extends to the operating device itself.

[0043] Here, the term "disaster prevention system" refers to emergency equipment that connects disaster prevention devices to a disaster prevention receiving panel to monitor a specific area such as inside a tunnel. The term "disaster prevention receiving panel" refers to a device that monitors and controls the connected disaster prevention devices and is positioned higher than the disaster prevention devices, and is a concept that includes a central monitoring device, receiver, control panel, etc.

[0044] Furthermore, "disaster prevention equipment" refers to equipment equipped with specified disaster prevention equipment including an operating device, and includes reporting devices and fire hydrant equipment, etc., and "fire hydrant equipment" refers to a type of emergency equipment installed in tunnels on expressways and motorways that are areas subject to firefighting, and is equipped with fire hydrant equipment such as fire hoses, electrical equipment such as red indicator lights and transmitters, and pump start-up devices that are operated when fire brigades use water hydrants, etc., and is a concept that includes fire hydrant facilities with fire hydrant equipment installed.

[0045] Furthermore, an "operating device" is a device equipped with a switch that closes (ON) or opens (OFF) a contact point by a predetermined pressing operation. The type, configuration, and structure of the "switch" are arbitrary, but it includes, for example, a "non-locking switch" equipped with a non-locking structure that closes (ON) the contact point when pressed and opens the contact point when not pressed, and a "locking switch" equipped with a locking structure that switches between a closed and open state when pressed and maintains the contact state even when the pressure is released.

[0046] Furthermore, when the disaster prevention device is a fire hydrant, the term "operating device" applies to, for example, the "transmitter" and "pump starter" installed on the fire hydrant. The "transmitter" is installed, for example, on the electrical door of the fire hydrant, and is operated by a road user to close the contacts of a switch and send a fire alert signal to the disaster prevention receiving panel. The "pump starter" is installed on the fire hydrant along with a water supply hydrant, and is operated by the fire brigade to close the contacts of a switch and send a pump start signal to the disaster prevention receiving panel. The "operating device" can also be applied to a "pump start interlocking device" that detects the opening of the hydrant valve of the fire hydrant device, closes the contacts of a switch (limit switch), and sends a pump start signal to the disaster prevention receiving panel in the same way as the pump starter.

[0047] The disaster prevention system of this embodiment is characterized in that the disaster prevention receiving panel is equipped with an inspection control unit that instructs the inspection operation of the switch of the operating device provided on the disaster prevention device, and the operating device is equipped with an inspection structure that activates the switch when it receives an instruction for inspection operation from the inspection control unit of the disaster prevention receiving panel.

[0048] Here, the "inspection control unit of the disaster prevention receiving panel" is a unit that instructs an inspection operation to an operating device installed in the disaster prevention device, and the method of instructing the inspection operation is arbitrary, but includes, for example, supplying a control power supply or sending an inspection instruction signal with a specified address.

[0049] In addition, when an inspection operation command is received from the inspection control unit of the disaster prevention receiving panel, the operating device activates a switch using the inspection structure, so during automatic inspection a signal is sent from the operating device to the disaster prevention receiving panel, and the disaster prevention receiving panel determines that the system is normal if it receives a signal from the operating device, and determines that there is a fault (abnormality) if it does not receive a signal.

[0050] In addition, the "inspection structure of the operating device" activates a switch when an inspection operation instruction is received from the inspection control unit of the disaster prevention receiving panel, and its structure is arbitrary, but it may, for example, comprise a case body, a pressing operation unit, an inspection drive unit, and a spring member.

[0051] Here, the "case body" refers to a predetermined cylindrical body, such as a cylinder, that is operated from one end and has a switch located inside the other end. The "pressing operation unit" refers to a member housed within the case body so that it can be moved to one end and pressed from the outside of that end in an initial position. The "inspection drive unit" refers to a member housed within the case body so that it can be moved from the pressing operation unit to the other end and pushes the drive shaft toward the other end of the case body when energized; for example, one such member uses a linear motor known as a voice coil motor (VCM). The "spring member" refers to a member housed within the case body so that it can be operated from the other end and holds the inspection drive unit and pressing operation unit in their initial positions.

[0052] Furthermore, if the inspection drive unit is a "linear motor," the "linear motor" is made, for example, of a magnetic material and includes a cylindrical yoke with an E-shaped cross section in the axial direction, which is the direction of movement of the inspection drive unit, and a movable coil arranged in the yoke so that a bobbin wound with a coil can be moved in the axial direction, and the drive shaft portion is arranged on the end face on the other end side of the movable coil.

[0053] With this inspection structure of the operating device, the switch of the operating device is activated by pressure from the drive shaft when the pressure operating part is pressed to move the inspection drive part against the spring member, and by pressure from the drive shaft being pushed out when electricity is applied to the inspection drive part, making it possible to activate the switch both by manual pressing and by electricity being applied during automatic inspection.

[0054] Furthermore, the "inspection structure" of the embodiment has a different structure depending on whether the switch is a "non-locking switch" or a "locking switch."

[0055] First, if the switch is a non-locking switch, it operates by closing the contacts when pressed and transmits a signal to the disaster prevention receiving panel only while pressed. Therefore, during inspection, by energizing the inspection drive unit for a predetermined period of time, signals can be continuously transmitted to the disaster prevention receiving panel. On the other hand, when a person presses the non-locking switch, it is unlikely that the person will continue to press the switch for the predetermined period of time, and therefore it is not guaranteed that the non-locking switch will be continuously pressed, and therefore signals cannot be continuously transmitted to the disaster prevention receiving panel. Therefore, the inspection structure for the non-locking switch is provided with a mechanism that maintains the closed state when the pressing operation unit is pressed to close the contacts of the non-locking switch. Note that maintaining the closed state of the non-locking switch when the pressing operation unit is pressed to close the contacts of the locking switch is not required, and an inspection structure that does not include a mechanism that maintains the closed state of the non-locking switch is not prohibited when the switch is a non-locking switch.

[0056] In contrast, if the switch is a locking switch, the locking switch will maintain its contact state even when released from the pressure, allowing signals to be sent to the disaster prevention receiving panel continuously regardless of whether it is being inspected automatically or manually pressed. Therefore, when the pressing operation part is pressed to close the contacts of the locking switch, a mechanism to maintain the closed state is not required, making it possible to simplify the inspection structure compared to that of a non-locking switch.

[0057] The inspection structure for an operating device equipped with a non-locking switch includes a case body, a pressing operation unit, an inspection drive unit, and a spring member, as well as a "rotation holding mechanism" that holds the non-locking switch in a closed state. Here, when the pressing operation unit presses the operating shaft while the operating unit is in its initial position, the "rotation holding mechanism" rotates and moves the inspection drive unit toward the other end, holding the non-locking switch in a predetermined position where the contacts of the non-locking switch are closed, and when the pressing operation unit is pressed while the inspection drive unit is held in the predetermined position, the inspection drive unit is released and rotated to its initial position, opening the contacts of the non-locking switch.

[0058] The "rotation holding mechanism" may have any configuration, but may include, for example, a rotation guide groove, a guide pin, a lock pin, and a guide opening.

[0059] Here, the "rotation guide groove" is formed on the outer periphery of the case body at a predetermined inclination angle with respect to the axial direction, which is the direction of movement of the inspection drive unit, and the "guide pin" is erected on the outer periphery of the inspection drive unit corresponding to the position of the rotation guide groove, and moves along the rotation guide groove to rotate the inspection drive unit in the axial direction.

[0060] Furthermore, the "lock pin" is an opening that stands upright on the drive shaft of the inspection drive unit, and the "guide opening" is an opening, for example, in the shape of a right triangle, that is formed on the cylindrical surface of the case body, is formed on the outer periphery of the case body, and is equipped with an inclined guide surface that guides the lock pin in a direction of a predetermined inclination angle as the inspection drive unit rotates and moves, and that engages the lock pin at a predetermined position that closes the contacts of the non-lock switch, and a linear guide surface that guides the lock pin in the axial direction when the drive shaft moves due to the application of electricity to the inspection drive unit.

[0061] In addition, the spring member applies a rotational restoring force to the inspection drive unit held by the lock pin engagement on the inclined guide surface of the guide opening, and when the lock pin engagement is released by pressing the pressing operating unit, the rotational restoring force pushes the inspection drive unit back to its initial position.

[0062] Therefore, during automatic inspection, the drive shaft of the inspection drive unit is pushed out by the guided movement of the lock pin along the linear guide surface of the guide opening, making it possible to close the contacts of the non-lock switch while power is applied. Also, during automatic inspection, the position of the inspection drive unit itself does not move, so the guide pin does not move along the rotary guide groove.

[0063] On the other hand, when a person presses the operation lever in an emergency, the guide pin moves along the rotary guide groove and the lock pin moves along the inclined guide surface of the guide opening, causing the inspection drive unit to rotate toward the other end, and the lock pin is locked, holding the inspection drive unit in a position where it closes the contacts of the non-lock switch. Also, when it is desired to open the contacts of the non-lock switch during recovery, the pressing operation unit is pressed again, which releases the lock pin, and the rotational restoring force of the spring member allows the inspection drive unit to return to its initial position.

[0064] Next, the inspection structure for an operating device equipped with a lock switch includes a case body, a pressing operation unit, an inspection drive unit, and a spring member, as well as a "guide mechanism." Here, the "guide mechanism" moves the inspection drive unit to the other end when the pressing operation unit is pressed, switching the contact state of the lock switch to either a closed or open state.

[0065] The "guide mechanism" may have any configuration, but may include, for example, a linear guide groove and a guide pin. Here, the "guide groove" is formed in the axial direction, which is the movement direction of the inspection drive unit, on the outer periphery of the case body, and the "guide pin" is erected on the outer periphery of the inspection drive unit in accordance with the position of the linear guide groove, and moves along the linear guide groove to move the inspection drive unit in the axial direction.

[0066] In this way, the inspection structure for an operating device equipped with a lock switch does not require a mechanism to hold the contacts of the lock switch in a closed position or a mechanism to guide movement at a predetermined inclination angle in the axial direction, and functions sufficiently by simply being equipped with a guide mechanism that guides movement in the axial direction.

[0067] Furthermore, the instructions for inspection operations sent from the disaster prevention receiving panel to the operating devices installed in the disaster prevention devices can be divided into P-type (Record-type) transmission, which issues inspection instructions for each signal wiring, and R-type (Proprietary-type) transmission, which issues inspection instructions by specifying an address. In other words, with P-type transmission, all operating devices of disaster prevention devices connected to one signal wiring are subject to automatic inspection, while with R-type transmission, any operating device of disaster prevention device can be subject to automatic inspection.

[0068] The configuration of the disaster prevention system and the method of automatic inspection are divided into four types depending on the type of switch (non-locking switch or locking switch) and the transmission method (P-type transmission or R-type transmission).

[0069] First, when the switch is a non-locking switch and the transmission method is P-type transmission, the signal wiring includes an operation wiring to which the switch of the operation device is branched and an inspection control wiring to which the inspection drive unit of the operation device and the inspection circuit unit that controls the inspection operation are branched. Note that the "wiring" is composed of, for example, a signal line and a common line, and the common line may be a common line shared by multiple lines.

[0070] The "inspection circuit section" also includes a delayed opening switch and a delayed closing switch. The "delayed opening switch" opens its contacts a predetermined time after being energized and is branch-connected to the inspection control wiring so as to be in series with the inspection drive section, while the delayed closing switch closes its contacts a predetermined time after being energized and is inserted and connected to the inspection control wiring that connects the disaster prevention devices. The inspection circuit section may be configured as desired, but for example, there is one that uses a time-delay relay, and in which the delayed opening switch is a "time-delay normally closed contact" that opens a predetermined time after the time-delay relay is energized, and the delayed closing switch is a "time-delay normally open contact" that closes a predetermined time after being energized.

[0071] The inspection control unit of the disaster prevention receiving panel also supplies a predetermined control power supply to the inspection control wiring as an instruction for the inspection operation. The automatic inspection operation of the disaster prevention device is as follows: First, when the predetermined control power supply is supplied via the inspection control wiring, the inspection drive unit energizes and closes the contacts of the non-locking switch, and the operating device sends a predetermined signal via the operating wiring to the disaster prevention receiving panel. Next, after a predetermined time has passed since energizing the inspection circuit unit, the inspection drive unit opens by opening the delay-opening switch, thereby de-energizing the inspection drive unit and opening the contacts of the non-locking switch. The operating device then stops transmitting the predetermined signal, and the delay-closing switch opens, supplying the predetermined control power supply via the inspection control wiring to the next-stage disaster prevention device. This similarly performs an automatic inspection operation on the next-stage disaster prevention device, and automatic inspections are performed sequentially on the disaster prevention devices connected to the first signal wiring.

[0072] Next, if the switch is a lock switch and the transmission method is P-type transmission, the "signal line" similarly includes the operation wiring and the inspection control wiring, and the inspection control unit of the disaster prevention receiving panel supplies a specified control power to the inspection control wiring as an instruction for the inspection operation.

[0073] In addition, the "inspection circuit unit" outputs a first control signal twice with a predetermined interval between them when it receives electricity from the inspection control wiring, and then outputs a second control signal with a predetermined interval between the second output of the first control signal, and is equipped with an inspection drive switch that closes the contacts with the first control signal and a transfer switch that opens the contacts with the second control signal.

[0074] The automatic inspection of the disaster prevention device involves the following steps: First, when a predetermined control power supply is supplied via the inspection control wiring, the inspection circuit unit outputs a first control signal to close the inspection drive switch, energizing the inspection drive unit; the inspection drive unit closes the contacts of the lock switch; and the operating device transmits a predetermined signal via the operating wiring to the disaster prevention receiving panel. Next, after a predetermined time has elapsed since the output of the first control signal, the inspection circuit unit outputs a second control signal to close the inspection drive switch, energizing the inspection drive unit; the inspection drive unit opens the contacts of the lock switch, which were held closed, and the operating device stops transmitting the predetermined signal. Finally, after a predetermined time has elapsed since the output of the second first control signal, the inspection circuit unit outputs a second control signal to close the transfer switch, supplying the predetermined control power supply to the next-stage disaster prevention device via the inspection control wiring. This automatically inspects the next-stage disaster prevention device in the same way, and automatic inspections are performed sequentially on the disaster prevention devices connected to the signal wiring.

[0075] Next, when the switch is a non-locking switch and the transmission method is R-type transmission, the "signal wiring" includes the operation wiring to which the switch of the operation device is branched and the power supply transmission wiring to which the inspection drive unit of the operation device and the transmission control unit that controls the inspection operation and signal transmission with the disaster prevention receiving panel are branched.

[0076] In addition, the "transmission control unit" is set with a unique address, and outputs a control signal for a predetermined time based on an inspection instruction signal that matches its own address received from the inspection control unit of the disaster prevention receiving panel via the power supply transmission wiring, An inspection drive switch that closes a contact point by a control signal is provided, and the inspection drive switch is branch-connected to the power supply transmission wiring so as to be in series with the inspection drive unit.

[0077] The inspection control unit of the disaster prevention receiving panel also transmits an inspection instruction signal with a specified address to the power supply / signal wiring as an instruction to perform an inspection. Then, when the transmission control unit receives an inspection instruction signal that matches its own address, the automatic inspection operation of the disaster prevention device is as follows: when the transmission control unit receives an inspection instruction signal that matches its own address, the transmission control unit outputs a control signal for a specified time to close the inspection drive switch for a specified time to energize the inspection drive unit, the inspection drive unit closes the contacts of the non-lock switch for a specified time, and the operation device transmits a specified signal to the disaster prevention receiving panel via the operation wiring for a specified time, making it possible to perform automatic inspection of any disaster prevention device by specifying an address at any time.

[0078] Next, if the switch is a lock switch and the transmission method is R-type transmission, the "signal wiring" similarly includes the operation wiring and the power supply combined transmission wiring. Also, the inspection control unit of the disaster prevention receiving panel sends an inspection instruction signal with a specified address to the power supply combined signal wiring as an instruction to perform the inspection operation.

[0079] In addition, the "transmission control unit" is set with a unique address, and outputs a control signal twice for a predetermined period of time based on an inspection instruction signal that matches its own address received from the inspection control unit of the disaster prevention receiving panel via the power supply / transmission wiring, and is equipped with an inspection drive switch that closes the contacts using the control signal, and the inspection drive switch is branch-connected to the power supply / transmission wiring so that it is in series with the inspection drive unit.

[0080] The automatic inspection operation of the disaster prevention device is as follows: when the transmission control unit receives an inspection instruction signal that matches its own address, the transmission control unit outputs a first control signal for a predetermined time, closing the inspection drive switch for a predetermined time and energizing the inspection drive unit, the inspection drive unit closes the contacts of the lock switch, and the operation device sends a predetermined signal to the disaster prevention receiving panel via the operation wiring. Subsequently, when a predetermined time has passed since the output of the first control signal, the transmission control unit outputs a second control signal for a predetermined time, closing the inspection drive switch for a predetermined time and energizing the inspection drive unit, the inspection drive unit opens the contacts of the lock switch that were held closed, and the operation device stops sending the predetermined signal, making it possible to perform automatic inspection of any disaster prevention device by specifying its address at any time.

[0083] [Outline of aP-type transmission disaster prevention system] First, we will explain the outline of the disaster prevention system, referring to Figure 1, which shows the outline of a P-type transmission disaster prevention system.

[0084] (a1. Disaster prevention receiving panel and fire hydrant equipment) As shown in Figure 1, the disaster prevention system has fire hydrant devices 10 installed at predetermined intervals along the length of the tunnel, for example, at intervals of 50 meters, with a predetermined number of installation sections, for example, a section with four fire hydrant devices 10, being considered as one section, and four fire hydrant devices 10 are connected in sequence to signal wiring 14 (signal cable) drawn out from the disaster prevention receiving panel 12 for each section. Note that the number of fire hydrant devices 10 connected to the signal wiring 14 in one section and the installation intervals of the fire hydrant devices 10 are optional.

[0085] In addition, the signal wiring 14 includes high-voltage signal wiring (signal cable) for commercial AC power sources and low-voltage signal wiring (signal cable) for specified DC voltage power sources, and in the embodiment, the low-voltage signal wiring is connected to an operating device equipped with a switch provided on the fire hydrant device 10.

[0086] The fire hydrant device 10 is provided with, for example, a transmitter 16 and a pump start-up device 18 as operating devices equipped with switches. When the switch of the transmitter 16 is operated, the transmitter 16 transmits a fire notification signal to the disaster prevention receiving panel 12 via a low-voltage signal wiring included in the signal wiring 14. When the switch of the pump start-up device 18 is operated, the pump start-up signal is transmitted to the disaster prevention receiving panel 12 via a low-voltage signal wiring included in the signal wiring 14.

[0087] The disaster prevention receiving panel 12 is provided with a monitoring control unit 20, which monitors the reception of a fire notification signal by the activation of the switch of the transmitter 16. When a fire notification signal is received, the disaster prevention receiving panel 12 outputs a fire alarm and controls the linkage of emergency equipment, such as displaying a warning sign installed at the tunnel entrance to prohibit entry into the tunnel.

[0088] In addition, the monitoring control unit 20 monitors the reception of a pump start signal due to the activation of the switch of the pump start device 18, and when a pump start signal is received, it controls the start of the fire pump equipment on the disaster prevention receiving panel 12 side to supply fire water to the fire hydrant device 10 side.

[0089] In addition, an inspection control unit 22 is provided in the disaster prevention receiving panel 12, and the transmitter 16 and pump starting device 18 provided in the fire hydrant device 10 are provided with an inspection structure for performing automatic inspection by activating a switch upon receiving an inspection operation instruction from the inspection control unit 22 of the disaster prevention receiving panel 12.

[0090] (a2. Fire hydrant device) Next, the fire hydrant device will be described. In this description, reference will be made to Fig. 2, which shows the fire hydrant device from the front (front), Fig. 3, which shows the fire hydrant device from the front (front) with the hydrant door, maintenance door, and fire extinguisher door open, and Fig. 4, which shows a partial cross section of the fire hydrant device as seen from above (top). The cross section shown in Fig. 4 is taken along the cutting line aa in Fig. 2.

[0091] 2 to 4, the X, Y, and Z directions are perpendicular to each other. Specifically, when looking at the front of the fire hydrant device equipped with various doors, the X direction is the left-right direction, the Y direction is the up-down direction, and the Z direction is the front-to-back direction. The +X side of the X direction is the right side, the -X side is the left side, the +Y side of the Y direction is the top side, the -Y side is the bottom side, and the +Z side of the Z direction is the front side, and the -Z side is the back side. This also applies to Figures 3 to 9 and 12 to 15.

[0092] As shown in Figure 2, the fire hydrant device 10 has a structure divided into a housing 26a, the interior of which serves as a fire hydrant storage section, and a housing 26b, the interior of which serves as a fire extinguisher storage section, and decorative frames 28a, 28b are attached to the front of the housings 26a, 26b.

[0093] The door opening of the decorative frame 28a of the housing 26a is divided into upper and lower halves, with a forward-leaning fire hydrant door 30 that opens downward on hinges 30a provided at the lower part of the door opening, and a maintenance door 32 that opens upward on hinges 32a provided at the upper part of the door opening, and the fire hydrant storage section inside stores fire hoses and valves including fire hydrant valves.

[0094] A fire extinguisher door 40 that opens sideways to the left on hinges 40a is provided on the left side of the door opening in decorative frame 28b of housing 26b, and stores, for example, two fire extinguishers 44 in the fire extinguisher storage area inside. In addition, a viewing window 42 is provided in fire extinguisher door 40 corresponding to the position of the stored fire extinguisher 44, making it possible to check whether or not the fire extinguisher 44 is present from outside.

[0095] An electrical door 34 that opens sideways to the right on a hinge 34a is provided on the right side of the door opening in the decorative frame 28b. The electrical door 34 is provided with an emergency notification device, for example, a red indicator light 36, a transmitter 16, and an answer lamp 38, and a telephone jack 35 is provided inside the housing of the electrical door 34, as shown in FIG.

[0096] The red indicator lights 36 are normally always lit, allowing the installation locations of the fire hydrant devices 10 to be identified from a distance. When a pump start signal is sent to the disaster prevention receiving panel from the pump start device 18 or the pump start interlocking device 60 (described later), the disaster prevention receiving panel controls the red indicator lights 36 of all the fire hydrant devices 10 to flash simultaneously.

[0097] In a first embodiment of the transmitter described below, the transmitter 16 is equipped with a non-locking switch, and when the transmitter 16 is operated, the switch contacts of the non-locking switch close and send a fire notification signal (transmission signal) to the disaster prevention receiving panel while the push button of the transmitter 16 is pressed and while the closed state of the switch contacts is maintained by a rotation holding mechanism of the inspection structure described below. Also, in a second embodiment of the transmitter described below, a locking switch is equipped, and when the transmitter 16 is operated, the switch contacts of the locking switch are maintained closed and send a fire notification signal (transmission signal) to the disaster prevention receiving panel. The transmitter 16 is also equipped with an inspection structure that operates the switch in response to an inspection operation command from the disaster prevention receiving panel to perform an automatic inspection.

[0098] The response lamp 38 lights up in response to a response signal transmitted from the disaster prevention receiving panel when the disaster prevention receiving panel receives a fire notification signal. The response lamp 38 is connected to the disaster prevention receiving panel via an interlocking switch for response lighting that is interlocked with the switch of the transmitter 16, and lights up when the interlocking switch for response lighting that is interlocked with the closure of the switch of the transmitter 16 is closed.

[0099] As shown in Figure 3, the right side of the hydrant storage section in the housing 26a is a valve storage section, and a water supply pipe 46 drawn in from the outside is connected to a water supply hydrant 48 and branches off to connect a fire hose 62 via a fire hydrant valve 50 and an automatic pressure regulating valve 52. The left side of the hydrant storage section in the housing 26a is a hose storage section, and the hose storage section is provided with a hose storage frame 64, which stores the fire hose 62 drawn in from below by winding it inward clockwise or counterclockwise. A water discharge nozzle 70 is attached to the tip of the fire hose 62 drawn out through a hose outlet 66 installed on the back side of the hydrant door 30, and the water discharge nozzle 70 is detachably held in a nozzle holder 68.

[0100] The fire hydrant valve 50 is opened and closed by a fire hydrant valve opening / closing lever 56 on an operation box 54 located on the back side of the fire hydrant door 30, and when the fire hydrant valve opening / closing lever 56 is opened, this movement is transmitted to an interlocking box 58 by a wire link, and the fire hydrant valve 50 is opened and closed remotely.

[0101] The interlocking box 58 is provided with a pump start interlocking device 60 that uses a limit switch or the like to detect the open position of the fire hydrant valve opening / closing lever 56, and the pump start interlocking device 60 closes the switch contacts of the limit switch to send a pump start signal (transmission signal) to the disaster prevention receiving panel, which controls the start of the fire pump equipment and also controls the red indicator lights 36 provided on all fire hydrant devices 10 to flash simultaneously.

[0102] Additionally, a pump start-up device 18 used by the fire brigade is installed inside the open maintenance door 32. When the push button of the pump start-up device 18 is pressed, the switch is held closed and, like the pump start-up interlocking device 60, a pump start-up signal (transmission signal) is sent to the disaster prevention receiving panel, which controls the start-up of the fire pump equipment and also controls the flashing of the red indicator lights 36 installed on all of the fire hydrant devices 10 all at once.

[0103] Furthermore, as in the case of the transmitter 16, the pump starting device 18 is provided with a non-locking switch when the first embodiment of the transmitter described later is applied, and is provided with a locking switch when the second embodiment of the transmitter described later is applied, and an inspection structure is provided for activating the switch in response to an inspection operation command from the disaster prevention receiving panel.

[0104] In addition, the switch of the pump start-up device 18 and the switch of the pump start-up interlocking device 60 are connected in parallel, so that when the disaster prevention receiving panel receives a pump start-up signal from either device, it controls the start-up of the fire pump equipment, etc.

[0105] 3 and 4, terminal boxes 45a and 45b equipped with terminal blocks are disposed on the interior rear surface of housing 26b behind fire extinguisher door 40. High-voltage signal wiring (signal cable) from the disaster prevention receiving panel is connected to the terminal block of terminal box 45a, and internal wiring for red indicator light 36 is also connected. Low-voltage signal wiring (signal cable) from the disaster prevention receiving panel is also connected to the terminal block of terminal box 45b, and internal wiring for transmitter 16, answer lamp 38, telephone jack 35, pump start-up device 18, pump start-up interlocking device 60, and an inspection circuit unit that controls automatic inspection of transmitter 16 and pump start-up device 18 is also connected. A cable rack 72 is disposed at the top of housing 26a, extending from near the center of the valve storage section to the hose storage section, and signal wiring for pump start-up device 18 and pump start-up interlocking device 60 is inserted through the cable rack 72.

[0106] Here, the transmitter 16 is equipped with a protective plate made of a transparent material such as glass that is held on the front side of the electrical door 34. When the protective plate is pushed in, it comes off from the front side of the electrical door 34, and the protective plate and push button press a switch located on the back side of the electrical door 34, and when the switch contacts of the switch are closed, the transmitter 16 transmits a fire notification signal to the disaster prevention receiving panel, and the pushed-in protective plate remains in a fallen state on the back side of the electrical door 34. For this reason, when recovering after a fire has been extinguished, the electrical door 34 must be opened, and the protective plate that has fallen off on the back side of the electrical door 34 must be returned to the front side of the electrical door 34 and held in place.

[0107] [b. First embodiment of transmitter equipped with non-locking switch] Next, a first embodiment of a transmitter having a non-lock switch as a switch will be described.

[0108] (b1. Inspection structure) First, the inspection structure provided in the first embodiment of the transmitter will be described. In this description, reference will be made to Fig. 5, which shows the first embodiment of the transmitter equipped with a non-locking switch; Fig. 6, which shows the first embodiment of the transmitter of Fig. 5 from the bottom (underside); and Fig. 7, which shows the linear motor. Note that Fig. 5(A) shows a cross section of the transmitter attached to the electrical door as seen from the left, Fig. 5(B) shows a cross section taken along line bb in Fig. 5(A), and Fig. 5(C) shows a cross section taken along line cc in Fig. 5(A). The directions in Fig. 7 are those when the transmitter is attached to the electrical door. Fig. 7(A) shows the appearance of the linear motor, Figs. 7(B) and (C) show cross sections taken from the left, Fig. 7(B) shows the state when not energized, and Fig. 7(C) shows the state when energized.

[0109] As shown in FIG. 5(A), the transmitter 16, excluding the protective plate 106, is attached and fixed to a mounting plate 75 located on the back side of the electrical door 34, and is provided with an inspection structure for a case body 76, a pressing operation unit 100, a linear motor 78, and a non-locking switch 95 equipped with a coil spring 85.

[0110] The case body 76 is, for example, a cylindrical body that is open on both the front and rear sides, and a flange portion 7610 formed on one end of the cylindrical body on the front side is attached and fixed to the attachment plate 75 with a screw 7612 and a nut 7614.

[0111] A pressing operation unit 100 constituting a push button is housed in the front side (one end side) of the cylinder of case body 76 so as to be movable in the axial direction (front-to-back direction). The pressing operation unit 100 has an operating shaft 102 that protrudes forward of case body 76, and operating shaft 102 extends forward of mounting plate 75 via a through-hole formed in mounting plate 75. A cap-shaped waterproof cover 103 made of soft synthetic resin, rubber, or the like is provided for operating shaft 102 that extends forward of mounting plate 75, and waterproof cover 103 is attached and fixed to mounting plate 75 when flange 7610 of case body 76 is fixed to mounting plate 75 with screws 7612 and nuts 7614.

[0112] A protective plate storage section 104 is provided between the electrical door 34 and the mounting plate 75 in accordance with the position of the operating shaft section 102 of the pressing operation section 100, and a protective plate 106 is held movably on the front side of the electrical door 34 corresponding to the position of the protective plate storage section 104, and is detached to the inside (rear side) by pressing from the front.

[0113] A linear motor 78 that functions as an inspection drive unit is housed at the rear side (other end side) of the pressing operation unit 100 stored at the front side of the case main body 76 and is freely movable in the axial direction (front-to-back direction), with a drive shaft portion 80 protruding rearward from the linear motor 78.

[0114] The linear motor 78 is a known motor, and as shown in FIG. 7, for example, it is composed of a yoke (drive unit main body) 7810 and a moving coil 7812. The yoke 7810 is made of a magnetic material, has a cylindrical hole that opens on one side (rear side), and has an E-shaped cross section in the axial direction (front-to-back direction). The moving coil 7812 has a coil 7816 wound around the outer periphery of a coil bobbin 7814, and is provided so as to be movable in the axial direction (front-to-back direction) relative to the cylindrical hole of the yoke 7810. When current is applied to the coil 7816 of the linear motor 78, a thrust force approximately proportional to the current flowing through the moving coil 7812 is generated by electromagnetic induction relative to the yoke 7810, and the moving coil 7812 is pushed out from the yoke 7810, as shown in FIG. 7(C).

[0115] In the linear motor 78 of this embodiment, the drive shaft portion 80 is arranged on the rear end surface of the coil bobbin 7814 of the moving coil 7812, and the drive shaft portion 80 may be formed integrally with the coil bobbin 7814, or may be prepared as a separate part from the coil bobbin 7814 and attached and fixed to the rear end surface of the coil bobbin 7814 by gluing or screwing, etc.

[0116] 5(A) again, a coil spring 85 functioning as a spring member is provided on the rear side of the case body 76 following the linear motor 78. One end of the coil spring 85 is fixed to the drive shaft 80 of the linear motor 78, and the other end is fixed to an insulating bottom cover 77 attached and fixed to the rear end (other end) of the case body 76, and the coil spring 85 presses the linear motor 78 and the pressing operation unit 100, which are located on the front side, forward to hold them in their initial positions.

[0117] A non-locking switch 95 is provided inside the outer lid 77 attached and fixed to the rear end of the case body 76. The non-locking switch 95 is a two-circuit switch that has a switch contact for the transmitter and a switch contact for turning on the response lamp, and the switch contact is closed (ON) when the switch knob 9510 is pressed, and the switch contact is opened (OFF) when the switch knob 9510 is released. In other words, the non-locking switch 95 opens the switch contact while the switch knob 9510 is pressed, and does not have the function of keeping the switch contact closed when the switch knob 9510 is not pressed.

[0118] Furthermore, the non-lock switch 95 has four lead terminals 9512 extending rearward through the bottom cover 77 corresponding to the two switch contact circuits, and internal wiring from the terminal box 45b shown in Figures 3 and 4 is connected to the lead terminals 9512. To energize the linear motor 78, two lead terminals 7820 extending rearward through the bottom cover 77 correspond to two lead wires 7818 extending from the linear motor 78, and internal wiring from the terminal box 45b is also connected to the lead terminals 7820. The bottom cover 77 is also provided with a terminal waterproof cover 98 that protects the lead terminals 9512 and 7820 extended rearward.

[0119] Automatic inspection of the transmitter 16 in response to an inspection operation command from the disaster prevention receiving panel is performed by energizing the linear motor 78. When the linear motor 78 is energized, the moving coil 7812 pushes the drive shaft 80 rearward against the coil spring 85, and the drive shaft 80 presses the switch knob 9510 of the non-lock switch 95 to close (turn on) the switch contacts, and the transmitter 16 transmits a fire alert signal to the disaster prevention receiving panel while the linear motor 78 is energized.

[0120] In contrast, in the event of an emergency such as a fire, a road user will press in the protective plate 106 arranged on the front side of the electrically equipped door 34, and by pressing the protective plate 106, the pressing operation unit 100 and the linear motor 78 will move backward against the coil spring 85, causing the drive shaft unit 80 to press in the switch knob 9510 of the non-lock switch 95 to close (turn on) the switch contacts, and the transmitter 16 will be able to send a fire alert signal to the disaster prevention receiving panel.

[0121] However, road users usually release their hands immediately after pressing the protective plate 106, and the switch contacts of the non-lock switch 95 are only closed (on) while the road user continues to press the protective plate 106. Therefore, the non-lock switch 95 is only closed temporarily, and the fire alarm signal cannot be continuously transmitted from the transmitter 16 to the disaster prevention receiving panel.

[0122] Therefore, in the first embodiment, the inspection structure of the transmitter 16 is provided with a rotation holding mechanism for holding the switch contact of the non-lock switch 95, which is closed by pressing the protective plate 106, in a closed state.

[0123] (b2. Rotational holding mechanism for inspection structure) Next, the rotation holding mechanism of the inspection structure of the first embodiment will be described, with reference to Figs.

[0124] 5 and 6, the rotation holding mechanism of this embodiment includes a rotation guide groove 84 and a guide pin 82. The rotation guide groove 84 is a groove formed at a predetermined inclination angle with respect to the axial direction (front-rear direction) of the cylindrical surface of the case main body 76. The guide pin 82 stands on the outer periphery of the yoke 7810 of the linear motion motor 78 and is inserted into the rotation guide groove 84. Here, as shown in FIGS. 5(A) and 5(B), the rotation guide groove 84 is formed at two opposing locations on the outer periphery of the case main body 76, for example, at the upper and lower parts, and the guide pins 82 similarly stand on two opposing locations on the outer periphery of the yoke 7810 of the linear motion motor 78 in accordance with the positions of the rotation guide groove 84.

[0125] Therefore, when the pressing operation unit 100 is pushed backward and moved, the guide pin 82 and the rotation guide groove 84 have the function of moving the linear motor 78 backward while rotating it around its axis against the coil spring 85.

[0126] 5 and 6, the rotation holding mechanism of this embodiment includes a lock pin 86 erected on the drive shaft 80 of the linear motor 78 and a guide opening 88 formed in the cylindrical surface of the case main body 76. As shown in Fig. 6, the guide opening 88 is, for example, a right-angled triangular opening, and is formed with a linear guide surface 90 and an inclined guide surface 92 that has a predetermined inclination angle with respect to the axial direction (front-rear direction). The inclined guide surface 92 guides and moves the lock pin 86 in the direction of the predetermined inclination angle as the pressing operation unit 100 moves rearward to rotate the linear motor 78, and is formed with a locking groove 94 that locks the lock pin 86 at a position where the drive shaft 80 presses the switch knob 9510 of the non-lock switch 95 to close the switch contacts.

[0127] Therefore, the lock pin 86 and the inclined guide surface 92 of the guide opening 88 have the function of rotating the linear motor 78 backward against the coil spring 85, and the function of keeping the switch contacts in a closed state when the drive shaft portion 80 presses the switch knob 9510 of the non-lock switch 95 to close the switch contacts.

[0128] Furthermore, when the linear motor 78 rotates backward against the coil spring 85, the coil spring 85 is compressed in the axial direction (front-to-back direction) and at the same time is wound around the axis, and when the lock pin 86 is fitted into the locking groove 94 of the inclined guide surface 92, a rotational restoring force is applied to the drive shaft portion 80 of the linear motor 78 via the lock pin 86 to return it to its initial position.

[0129] Therefore, when restoring the protective plate 106 of the transmitter 16 after it has been pressed, if the pressing operation unit 100 is pressed further, the lock pin 86 engaged in the engagement groove 94 of the inclined guide surface 92 is pushed and shifts rearward from the engagement groove 94, and is released from the engagement groove 94 by the rotational restoring force generated by the winding of the coil spring 85, and the linear motor 78 and pressing operation unit 100 move to their initial positions by the rotational restoring force of the coil spring 85, and the switch contacts of the non-lock switch 95 can be returned to the open state.

[0130] (b3. Automatic inspection of transmitter) Next, automatic inspection of the transmitter of the first embodiment will be described. In this description, reference will be made to Fig. 8, which shows the operation of the transmitter of the first embodiment during automatic inspection. Fig. 8(A) shows a cross section of the transmitter attached to the electrical door as seen from the left side, and Fig. 8(B) shows the transmitter attached to the electrical door as seen from the bottom (underside).

[0131] As shown in Figure 8(A), when automatically inspecting the transmitter 16, an inspection operation command is sent from the inspection control unit of the disaster prevention receiving panel to energize the linear motor 78. When the linear motor 78 is energized, a current flows through the coil 7816 shown in Figure 7, and a thrust force is generated by electromagnetic induction in the moving coil 7812 relative to the yoke 7810, and as the moving coil 7812 moves, the drive shaft 80 is pushed backward as shown by the arrow.

[0132] At this time, as shown in Figure 8 (B), the guide pin 86 standing on the drive shaft portion 80 moves rearward along the linear guide surface 96 of the guide opening 88, and the drive shaft portion 80 pushes in the switch knob 9510 of the non-lock switch 95. While current is being applied to the linear motor 78, the switch contacts of the non-lock switch 95 are closed and a fire alarm signal is sent to the disaster prevention receiving panel.

[0133] (b4. Manual operation of the transmitter) Next, manual operation of the transmitter of the first embodiment will be described. In this description, reference will be made to Fig. 9, which shows the operation of the transmitter of the first embodiment when manually operated. Fig. 9(A) shows a cross section of the transmitter attached to the electrical door as seen from the left side, and Fig. 9(B) shows the transmitter attached to the electrical door as seen from the bottom (underside).

[0134] As shown in Figure 9(A), in the event of an emergency such as a fire, when the protective plate 106 of the transmitter 16 provided on the electrically equipped door 34 is pushed in as shown by the arrow, the operating shaft 102 is pushed backward and the pressing operating part 100 moves backward, and accordingly the linear motor 78 rotates backward, and the switch knob 9510 of the non-lock switch 95 is pushed in by the drive shaft 80, closing the switch contacts and transmitting a fire alert signal to the disaster prevention receiving panel.

[0135] 9(B), the guide pin 82 standing on the yoke 7810 of the linear motor 78 moves along the rotation guide groove 84, and the linear motor 78 moves rearward against the coil spring 85 while rotating around its axis. In addition, the lock pin 86 standing on the drive shaft 80 moves along the inclined guide surface 92 of the guide opening 88, and when the lock pin 86 is positioned to close the switch contact of the non-lock switch 95, it fits into and locks into the lock groove 94, and the drive shaft 80 holds the non-lock switch 95 in the closed state.

[0136] If the closed state of the non-lock switch 95 is released during recovery, such as after the fire has been extinguished, by further pressing the pressing operation unit 100, the lock pin 86 is pushed out to a position where it is released from the locking groove 94, and at the same time, the rotational restoring force generated by the winding of the coil spring 85 pushes the linear motor 78 together with the pressing operation unit 100 back to its initial position, and the closed state of the non-lock switch 95 is released.

[0137] (b5. Pump starter inspection structure) Next, we will explain the inspection structure of the pump starting device. As shown in Figure 3, pump starting device 18 is exposed and operable when maintenance door 32 is opened. When a fire brigade connects a fire hose to hydrant 48 and presses the push button on pump starting device 18, a pump start signal is sent from pump starting device 18 to the disaster prevention receiving panel.

[0138] The inspection structure of the first embodiment of the pump starting device 18 is basically the same as the first embodiment of the transmitter 16 shown in Figures 5 to 7, that is, the inspection structure of the transmitter 16 attached and fixed to the mounting plate 75 is applied as the inspection structure of the pump starting device 18. However, the difference is that while the non-locking switch 95 of the transmitter 16 uses a switch with two switch contacts, in the case of the pump starting device 18, a switch contact for turning on the response lamp is not necessary, and therefore the non-locking switch 95 of the pump starting device 18 uses a switch with one switch contact.

[0139] [c. First embodiment of a disaster prevention system that automatically inspects the transmitter and pump starter of the first embodiment using P-type transmission] Next, a first embodiment of a disaster prevention system that automatically inspects the transmitter and pump starting device of the first embodiment by P-type transmission will be described.

[0140] (c1. Circuit configuration of transmitter and pump starter) The circuit configuration of the transmitter and pump starting device provided in the fire hydrant device will be described. In this description, reference will be made to Fig. 10, which shows the circuit configuration of the transmitter and pump starting device provided in the disaster prevention system of the first embodiment. Note that Fig. 10 shows the detailed circuit configuration of one fire hydrant device, and omits the circuit configurations of other fire hydrant devices that have basically the same configuration, showing only the block diagram of the fire hydrant device.

[0141] As shown in Figure 10, four fire hydrant devices 10 are connected to signal wiring 14 drawn from the disaster prevention receiving panel 12 to each installation section. The signal wiring 14 includes a transmitter line 110 for P-type transmission between the disaster prevention receiving panel 12 and the transmitter 16 and pump starting device 18 provided in each fire hydrant device 10, a response line 112, a pump starting line 114, an inspection control line 116 for automatic inspection of the transmitter 16 and pump starting device 18, and a common line 118 shared by these signal lines.

[0142] In the fire hydrant device 10, the switch contact 9514 of the non-lock switch 95 of the transmitter 16 is connected between the transmitter line 110 and the common line 118, and the interlock switch contact 9516 is connected between the response line 112 and the common line 118 together with the response lamp 38.

[0143] A predetermined voltage, for example, DC 48V, is supplied from the disaster prevention receiving panel 12 between the transmitter line 110 and the common line 118, and when the transmitter 16 is pressed to close the switch contact 9514, a wiring current flows from the transmitter line 110 to the common line 118, transmitting a fire alert signal to the disaster prevention receiving panel 12. At this time, the interlocking switch contact 9516 of the non-lock switch 95 is also closed.

[0144] The disaster prevention receiving panel 12 that receives the fire notification signal controls the interlocking of the emergency equipment and supplies a predetermined voltage, for example, DC 48V, between the response line 112 and the common line 118. Since the interlocking switch contact 9516 of the non-lock switch 95 is closed, the response lamp 38 lights up, and the fire hydrant device 10 notifies the user that the fire notification signal has been received and processed normally.

[0145] Furthermore, in the fire hydrant apparatus 10, the switch contact 1814 of the non-lock switch 1812 of the pump starting device 18 is connected between the pump starting line 114 and the common line 118. A predetermined voltage, for example, DC 48 V, is supplied from the disaster prevention receiving panel 12 between the pump starting line 114 and the common line 118, and when the pump starting device 18 is pressed to close the switch contact 1814, a wiring current flows from the pump starting line 114 to the common line 118, and a pump start signal is sent to the disaster prevention receiving panel 12 to control the pump start.

[0146] In addition, the switch contact 6010 of the pump start-up interlocking device 60 is connected in parallel to the switch contact 1814 of the pump start-up device 18, and when the switch contact 6010 is closed by opening the fire hydrant valve opening / closing lever, a pump start-up signal is similarly sent to the disaster prevention receiving panel 12 to perform pump start-up control.

[0147] In addition, in the fire hydrant device 10, a direct-acting motor (DM) 78 with an inspection structure provided in the transmitter 16, a direct-acting motor (DM) 1810 with an inspection structure provided in the pump starting device 18, and a time-delay relay (TR) 120 as an inspection circuit section for performing automatic inspection of the transmitter 16 and the pump starting device 18 are connected to the inspection control line 116 and the common line 118.

[0148] The time relay 120 has time-limit normally closed contacts 124, 126 that open a predetermined time after energization, and a time-limit normally open contact 122 that closes a predetermined time after energization. The time-limit normally closed contact 124 is connected in series with the direct-acting motor 78 of the transmitter 16, the time-limit normally closed contact 126 is connected in series with the direct-acting motor 1810 of the pump starting device 18, and the time-limit normally open contact 122 is inserted into and connected to the inspection control line 116 for the fire hydrant device 10 of the next stage.

[0149] The circuit configuration of this type of fire hydrant device 10 is basically the same for the remaining three fire hydrant devices 10, but the final stage fire hydrant device 10 (the rightmost fire hydrant device 10 in Figure 10) does not have a time-limited normally-open contact 122 because there is no next stage fire hydrant device.

[0150] (b2. Automatic inspection control) Next, the automatic inspection control of the transmitter and pump starting device shown in Fig. 10 will be explained. In this explanation, reference will be made to Fig. 11, which is a time chart showing the operating states of each part by the inspection circuit part of Fig. 10. Note that the inspection control line 116 in Fig. 11 (A) refers to the inspection control line 116 from the disaster prevention receiving panel 12 to the time-limited normally open contact 122 of the first stage fire hydrant device 10, and the inspection control line 116 in Fig. 11 (I) refers to the inspection control line 116 from the time-limited normally open contact 122 of the first stage fire hydrant device 10 to the time-limited normally open contact 122 of the second stage fire hydrant device 10.

[0151] The inspection control unit 22 of the disaster prevention receiving panel 12 shown in Fig. 10 automatically inspects the transmitters 16 and pump starting devices 18 at predetermined intervals, for example, once a day, for each group of four fire hydrant devices 10 connected to one signal wiring 14. In addition to being performed periodically, the automatic inspection of the transmitters 16 and pump starting devices 18 by the disaster prevention receiving panel 12 can also be performed at any time as needed by operating an inspection instruction, etc.

[0152] 11(A), at time t1, the inspection control unit 22 of the disaster prevention receiving panel 12 supplies DC 48V between the inspection control line 116 and the common line 118 as an inspection operation instruction for the fire hydrant device 10. Note that at time t1, the time-limited normally-open contact 122 of the first-stage fire hydrant device 10 is off (open), so DC 48V is not supplied to the second-stage or subsequent fire hydrant devices 10.

[0153] Therefore, in the first stage fire hydrant device 10, as shown in Figure 11(B), the time-limit relay 120 turns on (operates) at time t1, and as shown in Figures 11(C) and (D), at time t3, when a predetermined delay time Td has elapsed from time t1, the time-limit normally open contact 122 is changed from off (open) to on (closed), and the time-limit normally closed contacts 124, 126 are changed from on (closed) to off (open).

[0154] Also, in the first stage fire hydrant device 10, as shown in Figure 11 (E), the linear motor 78 of the transmitter 16 is turned on (operated) by energizing at time t1, and as shown in Figure 11 (F), at time t2, the drive shaft portion presses the switch knob of the non-lock switch 95, changing the switch contact 9514 of the non-lock switch 95 of the transmitter 16 from off (open) to on (closed), and the transmitter 16 transmits a fire alert signal to the disaster prevention receiving panel 12.

[0155] Also, in the first stage fire hydrant device 10, as shown in Figure 11 (G), the direct-acting motor 1810 of the pump starting device 18 is turned on (operated) by being energized at time t1, and as shown in Figure 11 (H), at time t2, the drive shaft portion pushes the switch knob of the non-lock switch 1812, changing the switch contact 1814 of the pump starting device 18 from off (open) to on (closed), and the pump starting device 18 transmits a pump start signal to the disaster prevention receiving panel 12.

[0156] Furthermore, in the first stage fire hydrant device 10, as shown in FIG. 11(E), at time t3, the time-limit normally closed contact 124 of the time-limit relay 120 changes from on (closed) to off (open), so that the current flow stops and the linear motor 78 turns off (non-operating), and as shown in FIG. 11(F), at time t4, the drive shaft returns to its initial position, so that the switch contact 9514 of the non-lock switch 95 of the transmitter 16 turns off (open).

[0157] Furthermore, in the first stage fire hydrant device 10, as shown in Figure 11 (G), at time t3, the time-limit normally closed contact 126 of the time-limit relay 120 changes from on (closed) to off (open), so that the current flow stops and the linear motor 1810 turns off (non-operating), and as shown in Figure 11 (H), at time t4, the drive shaft returns to its initial position, so that the switch contact 1814 of the non-lock switch 1812 of the pump starting device 18 turns off (open).

[0158] Furthermore, in the first stage fire hydrant device 10, at time t3, the time-limited normally open contact 122 of the time-limited relay 120 changes from off (open) to on (closed), and DC 48V is supplied to the next stage (second stage) fire hydrant device 10, and as shown in Figures 11(I) to (P), automatic inspection is performed on the transmitter 16 and pump starting device 18 installed in the second stage fire hydrant device 10, and automatic inspection is performed sequentially up to the final stage fire hydrant device 10.

[0159] Also, as shown in FIG. 11, time t5 (when the switch contacts 9514 and 1814 of the second-stage fire hydrant device 10 are turned on) is set to occur after a predetermined time has elapsed from time t4 (when the switch contacts 9514 and 1814 of the first-stage fire hydrant device 10 are turned off). This prevents the timing of automatic inspections at each fire hydrant device from overlapping by turning off (opening) the switch contacts 9510 and 1814 of the non-lock switches 95 and 1812 of the transmitter 16 and pump starting device 18 provided in the next-stage fire hydrant device 10 before they turn on (closed) the switch contacts 9514 and 1814 of the non-lock switches 95 and 1812 of the transmitter 16 and pump starting device 18 provided in the same fire hydrant device 10.

[0160] [d. Second embodiment of transmitter equipped with lock switch] Next, a second embodiment of a transmitter having a lock switch as a switch will be described.

[0161] (d1. Inspection structure) First, the inspection structure provided in the second embodiment of the transmitter will be described with reference to Fig. 12, which shows the second embodiment of the transmitter equipped with the lock switch inspection structure, and Fig. 13, which shows the first embodiment of the transmitter in Fig. 12 from the bottom (underside).

[0162] 12, the transmitter 16 of the second embodiment is, like the first embodiment, mounted and fixed to the mounting plate 75 arranged on the back side of the electrical door 34, except for the protective plate 106, and includes a case body 76, a pressing operation unit 100, a linear motor 78, and an inspection structure for the lock switch 96 equipped with a coil spring 132. Note that the case body 76 and the pressing operation unit 100 are similar to those of the first embodiment described above, and therefore the same reference numerals are used and their description will be omitted.

[0163] A linear motor 78 that functions as an inspection drive unit is housed movably in the axial direction (front-to-back direction) behind the pressing operation unit 100, which is disposed on the front side of the case main body 76. The linear motor 78 has a drive shaft 80 that protrudes rearward from a yoke 7810, and the drive shaft 80 is disposed on the end face on the rear end side of a moving coil disposed inside the yoke 7810. Details of the linear motor 78 are as shown in FIG.

[0164] A coil spring 132 is provided on the rear side of the case body 76, following the linear motor 78. One end of the coil spring 132 is fixed to the drive shaft 80 of the linear motor 78, and the other end is fixed to the insulating bottom cover 77 attached and fixed to the rear end of the case body 76, and presses the linear motor 78 and the pressing operation unit 100, which are located on the front side, forward to hold them in their initial positions.

[0165] A lock switch 96 is provided inside outer lid 77 attached and fixed to the rear end of case main body 76. Lock switch 96 is a two-circuit switch that has a switch contact for the transmitter and a switch contact for response lighting of the response lamp, and when switch knob 9610 is pressed, the switch contact is closed (ON), and the switch contact is maintained in the closed (ON) position even when switch knob 9610 is released. Furthermore, when switch knob 9610 is pressed while the switch contact is maintained in the closed position, the switch contact is opened (OFF), and the switch contact is maintained in the open (OFF) position even when switch knob 9610 is released.

[0166] The lock switch 96 has four lead terminals 9612 extending rearward through the bottom cover 77 corresponding to the two switch contacts, and internal wiring from the terminal box 45b shown in Figures 3 and 4 is connected to the lead terminals 9612. To energize the linear motor 78, two lead terminals 7820 extending rearward through the bottom cover 77 correspond to two lead wires 7818 extending from the linear motor 78, and internal wiring from the terminal box 45b is also connected to the lead terminals 7820. The bottom cover 77 is also provided with a terminal waterproof cover 98 that protects the lead terminals 9612 and 7820 extended rearward.

[0167] Automatic inspection of the transmitter 16 in response to an inspection operation command from the disaster prevention receiving panel is performed by energizing the linear motor 78 twice with a predetermined time between them. The linear motor 78 pushes the drive shaft 80 rearward during the first energization, and the drive shaft 80 presses the switch knob 9610 of the lock switch 96 to close (turn on) the switch contacts, causing the transmitter 16 to send a fire alert signal to the disaster prevention receiving panel. Then, even after the first energization is stopped and the drive shaft 80 of the linear motor 78 returns to its initial position, the lock switch 96 maintains the switch contacts in the closed (on) state.

[0168] Next, the linear motor 78 is energized a second time, again pushing the drive shaft 80 rearward, and the drive shaft 80 presses the switch knob 9610 of the lock switch 96, which keeps the switch contacts closed, to open (off) the switch contacts, and the transmitter 16 stops transmitting the fire alert signal. Then, even when the second energization is stopped and the drive shaft 80 of the linear motor 78 returns to its initial position, the switch contacts remain open (off). Therefore, the transmitter 16 transmits the fire alert signal to the disaster prevention receiving panel during the period from when the switch contacts of the lock switch 96 are closed (on) by the first energization of the linear motor 78 until the switch contacts of the lock switch 96 are opened (off) by the second energization.

[0169] Furthermore, in the event of an emergency such as a fire, if a road user presses the protective plate 106 arranged on the front side of the electrically equipped door 34, the pressing operation of the protective plate 106 causes the pressing operation unit 100 and the linear motor 78 to move rearward against the coil spring 132, causing the drive shaft unit 80 to press the switch knob 9610 of the lock switch 96 to close (turn on) the switch contacts, and this closed (on) state is maintained, allowing the transmitter 16 to continuously transmit a fire alert signal to the disaster prevention receiving panel.

[0170] Therefore, in the second embodiment, the inspection structure of the transmitter 16 does not include a mechanism for keeping the switch contacts in a closed state, but instead includes a guide mechanism for closing or opening the switch contacts of the lock switch 96 by pressing the protective plate 106.

[0171] (d2. Guidance mechanism for inspection structure) Next, the guide mechanism of the inspection structure of the second embodiment will be described with reference to FIGS.

[0172] 12 and 13 , the guide mechanism of this embodiment includes a linear guide groove 130 formed in the axial direction (front-rear direction) of the cylindrical surface of the case main body 76, and a guide pin 82 that stands on the outer periphery of the yoke 7810 of the linear motor 78 and is inserted into the linear guide groove 130. Here, as shown in FIG. 12 , the linear guide groove 130 is formed at two opposing locations in the diameter direction of the case main body 76, for example, at the top and bottom, and the guide pin 82 similarly stands on two opposing locations on the outer periphery of the yoke 7810 of the linear motor 78 in correspondence with the positions of the linear guide groove 130. Therefore, the guide pin 82 and the linear guide groove 130 have the function of guiding the linear motor 78 to move rearward against the coil spring 132 when the pressing operation unit 100 is pushed rearward and moved.

[0173] (d3. Automatic inspection of transmitters) Next, automatic inspection of the transmitter of the second embodiment will be described. In this description, reference will be made to Fig. 14, which shows the operation of the transmitter of the second embodiment during automatic inspection. Fig. 14(A) shows a cross section of the transmitter attached to the electrical door as seen from the left side, and Fig. 14(B) shows the transmitter attached to the electrical door as seen from the bottom (underside).

[0174] As shown in Figure 14(A), when automatically inspecting the transmitter 16, the inspection control unit of the disaster prevention receiving panel issues an inspection operation command to energize the linear motor 78 twice with a predetermined interval between them. When the linear motor 78 is energized the first time, the drive shaft 80 is pushed backward as shown by the arrow.

[0175] 14(B), the guide pin 82 standing on the yoke 7810 does not move, and the drive shaft 80 pushes in the switch knob 9610 of the lock switch 96, closing the switch contacts of the lock switch 96 and transmitting a fire alert signal to the disaster prevention receiving panel. When the first energization is completed, the drive shaft 80 returns to its initial position and the switch knob 9610 is released from being pressed, but the lock switch 96 remains closed.

[0176] Subsequently, when the linear motor 78 is energized a second time after a predetermined time, the drive shaft 80 is similarly pushed rearward and the drive shaft 80 again pushes in the switch knob 9610 of the lock switch 96, opening the switch contacts of the lock switch 96, which are in the closed state, and stopping the transmission of the fire alert signal. When the second energization of the linear motor 78 is completed, the drive shaft 80 returns to its initial position and the switch knob 9610 is released, but the lock switch 96 remains in the open state.

[0177] (d4. Manual operation of the transmitter) Next, manual operation of the transmitter of the second embodiment will be described. In this description, reference will be made to Fig. 15, which shows the operation of the transmitter of the second embodiment when manually operated. Fig. 15(A) shows a cross section of the transmitter attached to the electrical door as seen from the left side, and Fig. 15(B) shows the transmitter attached to the electrical door as seen from the bottom (underside).

[0178] As shown in Figure 15(A), in an emergency such as a fire, when the protective plate 106 of the transmitter 16 provided on the electrically equipped door 34 is pressed as shown by the arrow, the operating shaft 102 is pushed backward, causing the pressing operation unit 100 to move backward, which in turn causes the linear motor 78 to move backward. The drive shaft 80 presses the switch knob 9610 of the lock switch 96, closing the switch contacts and transmitting a fire alert signal to the disaster prevention receiving panel. At this time, as shown in Figure 15(B), the guide pin 82 erected on the yoke 7810 of the linear motor 78 moves along the linear guide groove 130, causing the linear motor 78 to move backward against the coil spring 85. When the operating shaft 102 is released, the pressing operation unit 100 and the linear motor 78 return to their initial positions, and the switch knob 9610 is released, but the switch contacts of the lock switch 96 remain closed.

[0179] When the non-lock switch 95 is released from the closed state upon recovery, such as after the fire has been extinguished, the linear motor 78 is pressed in by the pressing operation unit 100, and the switch knob 9610 of the lock switch 96 is pressed in by the drive shaft 80 of the linear motor 78, opening (turning off) the switch contacts that are in the closed state. Furthermore, when the operation shaft 102 is released from being pressed in, the pressing operation unit 100 and the linear motor 78 return to their initial positions and the switch knob 9610 is released from being pressed in, but the switch contacts of the lock switch 96 are held in the open state, and the transmission of the fire alert signal to the disaster prevention receiving panel is stopped.

[0180] (d5. Pump starter inspection structure) Next, we will explain the inspection structure of the pump starting device. As shown in Figure 3, pump starting device 18 is exposed and operable when maintenance door 32 is opened. When a fire brigade connects a fire hose to hydrant 48 and presses the push button on pump starting device 18, a pump start signal is sent from pump starting device 18 to the disaster prevention receiving panel.

[0181] The inspection structure of the second embodiment of the pump starting device 18 is basically the same as the second embodiment of the transmitter 16 shown in Figures 12 and 13, that is, the inspection structure of the transmitter 16 attached and fixed to the mounting plate 75 is applied as the inspection structure of the pump starting device 18. However, the difference is that while the lock switch 96 of the transmitter 16 uses a switch with two switch contacts, in the case of the pump starting device 18, a switch contact for turning on the response lamp is not necessary, and therefore the lock switch 96 of the pump starting device 18 uses a switch with one switch contact.

[0182] [e. Second embodiment of disaster prevention system that automatically inspects the transmitter and pump starter of the second embodiment using P-type transmission] Next, a second embodiment of a disaster prevention system that automatically inspects the transmitter and pump starting device of the second embodiment using P-type transmission will be described. In this description, reference will be made to Fig. 16, which shows the circuit configuration of the transmitter and pump starting device provided in the disaster prevention system of the second embodiment, Fig. 17, which is a time chart showing the operating states of each part by the inspection circuit unit of Fig. 16, Fig. 18, which shows an example of the inspection circuit unit of Fig. 16, and Fig. 19, which is a time chart showing the operating states of each part in the inspection circuit unit of Fig. 18. Note that Fig. 16 shows the detailed circuit configuration of one fire hydrant device, and omits the circuit configurations of other fire hydrant devices that have basically the same configuration, showing only the blocks of the fire hydrant device. 17(A) indicates the inspection control line 116 from the disaster prevention receiving panel 12 to the time-limited normally open contact 122 of the first-stage fire hydrant device 10, and the inspection control line 116 of (J) indicates the inspection control line 116 from the time-limited normally open contact 122 of the first-stage fire hydrant device 10 to the time-limited normally open contact 122 of the second-stage fire hydrant device 10. Also, FIG. 19 shows the operating states of each part in the inspection circuit section of the first-stage fire hydrant device 10 in FIG.

[0183] (e1. Circuit configuration of transmitter and pump starter) First, we will explain the transmitter and pump starting device inspection circuit section of the second embodiment installed in the fire hydrant device. As shown in Figure 16, four fire hydrant devices 10 are connected to signal wiring 14 drawn from a disaster prevention receiving panel 12 to each installation section. As in the first embodiment, the signal wiring 14 includes a transmitter line 110, a response line 112, a pump starting line 114, an inspection control line 116, and a common line 118.

[0184] In the fire hydrant device 10, the switch contact 9614 of the lock switch 96 of the transmitter 16 is connected between the transmitter line 110 and the common line 118, and the interlock switch contact 9616 is connected between the response line 112 and the common line 118 together with the response lamp 38.

[0185] A predetermined voltage, for example, DC 48V, is supplied from the disaster prevention receiving panel 12 between the transmitter line 110 and the common line 118, and when the transmitter 16 is pressed to close the switch contact 9614, a wiring current flows from the transmitter line 110 to the common line 118, transmitting a fire alert signal to the disaster prevention receiving panel 12. At this time, the interlocking switch contact 9616 of the lock switch 96 is also closed.

[0186] The disaster prevention receiving panel 12 that receives the fire notification signal controls the linkage of the emergency equipment and supplies a predetermined voltage, for example, DC 48V, between the response line 112 and the common line 118. Since the linkage switch contact 9616 of the lock switch 96 is closed, the response lamp 38 lights up, and the fire hydrant device 10 notifies the user that the fire notification signal has been received and processed normally.

[0187] Furthermore, in the fire hydrant apparatus 10, a switch contact 1822 of a lock switch 1820 of the pump starting device 18 is connected between the pump starting line 114 and the common line 118. A predetermined voltage, for example, DC 48 V, is supplied from the disaster prevention receiving panel 12 between the pump starting line 114 and the common line 118, and when the pump starting device 18 is pressed to close the switch contact 1822, a wiring current flows from the pump starting line 114 to the common line 118, and a pump start signal is transmitted to the disaster prevention receiving panel 12, causing pump start control to be performed.

[0188] In addition, the switch contact 6010 of the pump start-up interlocking device 60 is connected in parallel to the switch contact 1822 of the pump start-up device 18, and when the switch contact 6010 is closed by opening the fire hydrant valve opening / closing lever, a pump start-up signal is similarly sent to the disaster prevention receiving panel 12 to perform pump start-up control.

[0189] In addition, in the fire hydrant device 10, a direct-acting motor (DM) 78 with an inspection structure provided in the transmitter 16, a direct-acting motor (DM) 1810 with an inspection structure provided in the pump starting device 18, and an inspection circuit unit 134 for performing automatic inspection of the transmitter 16 and the pump starting device 18 are connected to the inspection control line 116 and the common line 118.

[0190] In addition, the inspection circuit section 134 is equipped with inspection drive switches 136, 138 and a transfer switch 140, the direct-acting motor (DM) 78 is connected to the inspection control line 116 and the common line 118 via the inspection drive switch 136, the direct-acting motor (DM) 1810 is connected to the inspection control line 116 and the common line 118 via the inspection drive switch 138, and the transfer switch 140 is inserted and connected to the inspection control line 116 for the next-stage fire hydrant device 10.

[0191] The inspection circuit unit 134 operates by receiving a predetermined voltage, for example, DC 48V, supplied between the inspection control line 116 and the common line 118 by the inspection control unit 22 of the disaster prevention receiving panel 12 as an inspection operation instruction during automatic inspection, and outputs a control signal E11 twice to the inspection drive switches 136, 138 to operate the direct-acting motor 78 of the transmitter 16 and the direct-acting motor 1810 of the pump starting device 18 twice with a predetermined time between them, and after outputting the second control signal E11, outputs a control signal E12 to the transfer switch 140.

[0192] The inspection circuit unit 134 may have any configuration, but may have, for example, the circuit configuration shown in Fig. 18. As shown in Fig. 18, the inspection circuit unit 134 includes a shift register 142, a register 146, a clock generating unit 144, AND gates 148, 150, 154, 156, and an OR gate 152.

[0193] 19(B), the clock generating unit 144 outputs a clock signal with a predetermined period Tc to a 5-bit shift register 142. Here, the length of the clock period Tc can be arbitrary, but the time at which the lock switches 96, 1820 of the transmitter 16 and pump starting device 18 are activated to transmit a fire alert signal and a pump start signal to the disaster prevention receiving panel during inspection is determined by the clock period Tc, which is set to, for example, 1 second. The register 146 also functions as a bit 1 setter that continuously supplies a logic level 1 signal as an input to the shift register 142.

[0194] As shown in Figure 19(A), when DC 48V is supplied through the inspection control line 116 at time t1, the inspection circuit unit 134 starts operating, and the shift register 142 reads a signal of logic level 1 from the register 146 in synchronization with the rising edge of the clock signal from the clock generating unit 144.

[0195] Therefore, the data bits b1 to b5 of the shift register 142 change as follows in response to the first to fifth clocks. 1st clock: (b1, b2, b3, b4, b5) = (10000) Second clock: (b1, b2, b3, b4, b5) = (11000) 3rd clock: (b1, b2, b3, b4, b5) = (11100) 4th clock: (b1, b2, b3, b4, b5) = (11110) 5th clock: (b1, b2, b3, b4, b5) = (11111)

[0196] The AND gate 148 receives data bits b1 and b2 from the shift register 142, with data bit b2 being inverted. Therefore, the output of the AND gate 148 becomes logic level 1 when data bits b1 and b2 (10000) obtained by the data shift using the first clock are input. As shown in FIG. 19C, at time t1, the OR gate 152 outputs a first control signal E11, turning on (closing) the inspection drive switches 136 and 138, operating the linear motor 78 of the transmitter 16 and the linear motor 1810 of the pump starter device 18, and closing (on) the switch contacts 9614 and 1822 of the respective lock switches 96 and 1820, thereby initiating transmission of the fire alarm signal and the pump start signal. Furthermore, the AND gate 148 receives data bits b1 and b2 (11000) obtained by the data shift using the second clock, and outputs logic level 0.

[0197] The AND gate 150 receives data bits b3 and b4 from the shift register 142, with data bit b4 being inverted. Therefore, the output of the AND gate 150 becomes logic level 1 when data bits b3 and b4 (11100) obtained by the data shift using the third clock signal are input. As shown in FIG. 19C, the OR gate 152 outputs a second control signal E11 at time t2, causing the linear motor 78 of the transmitter 16 and the linear motor 1810 of the pump starter 18 to operate again, opening (turning on) the switch contacts 9614 and 1822 of the lock switches 96 and 1820, which are in the closed (on) state, and stopping the transmission of the fire alarm signal and the pump start signal. Furthermore, the AND gate 150 receives data bits b3 and b4 (11110) obtained by the data shift using the fourth clock signal, and outputs a logic level 0.

[0198] In addition, as shown in Figure 19 (D), the shift register 142 outputs the data bit b5, which has become the logic level 1 of (11111) obtained by the data shift using the fifth clock at time t3, as the control signal E12, and by closing (turning on) the transfer switch 140 using the control signal E12, DC 48V is supplied to the next-stage fire hydrant device 10, causing the next-stage fire hydrant device to perform an inspection operation.

[0199] In addition, the output of data bit b5 of shift register 142 is inverted and input to AND gate 156, and when control signal E12 (data bit b5 that has become logic level 1) is output, AND gate 156 is put into a prohibited state, fixing data bits b1 to b5 of shift register 142, and maintaining the closed (on) state of transfer switch 140 by control signal E12.

[0200] (e2. Automatic inspection control) Next, we will explain the automatic inspection control of the transmitter and pump starting device shown in Figure 16. The inspection control unit 22 of the disaster prevention receiving panel 12 shown in Figure 16 automatically inspects the transmitters 16 and pump starting devices 18 at predetermined intervals, for example, once a day, for four fire hydrant devices 10 connected to one signal wiring 14 as one unit. Note that the automatic inspection of the transmitters 16 and pump starting devices 18 by the disaster prevention receiving panel 12 can be performed periodically, or at any time as needed by issuing an inspection instruction operation, etc.

[0201] As shown in Fig. 17(A), the inspection control unit 22 of the disaster prevention receiving panel 12 supplies DC 48V between the inspection control line 116 and the common line 118 at time t1 as an inspection operation instruction for the fire hydrant device 10. Therefore, as shown in Fig. 17(B), the inspection circuit unit 134 turns on (operates) at time t1, and as shown in Fig. 17(C), it outputs a first control signal E11 and stops outputting the first control signal E11 after a lapse of time Ts. Note that time Ts is the same as the clock period Tc shown in Fig. 19.

[0202] 17(E), the linear motor 78 of the transmitter 16 is turned on (operated) by energization at time t1, and as shown in Fig. 17(F), the drive shaft presses the switch knob of the lock switch 96, changing the switch contact 9614 of the lock switch 96 from off (open) to on (closed), causing the transmitter 16 to transmit a fire alert signal to the disaster prevention receiving panel 12. Furthermore, when the output of the first control signal E11 stops, the linear motor 78 is de-energized and turned off (inoperative), and the drive shaft no longer presses the switch knob of the lock switch 96, but the switch contact 9614 of the lock switch 96 remains in the on (closed) state.

[0203] 17(G), linear motor 1810 of pump starting device 18 is turned on (operated) by energization at time t1, and as shown in Fig. 17(H), the drive shaft presses the switch knob of lock switch 1820, changing switch contact 1822 of lock switch 1820 from off (open) to on (closed), and pump starting device 18 transmits a pump start signal to disaster prevention receiving panel 12. When the output of the first control signal E11 stops, energization stops and the switch becomes off (non-operating), and the drive shaft releases the depression of the switch knob of lock switch 1820, but switch contact 1822 of lock switch 1820 remains in the on (closed) state.

[0204] Subsequently, as shown in FIG. 17(C), the inspection circuit unit 134 outputs the second control signal E11 at time t2, and stops outputting the second control signal E11 after a time Ts has elapsed.

[0205] 17(E), the linear motor 78 of the transmitter 16 is turned on (operated) again by energization at time t2, and as shown in Fig. 17(F), the switch contact 9514 of the lock switch 96, which has been held in the on (closed) state, is turned off (open), stopping the transmission of the fire alert signal to the disaster prevention receiving panel 12. Furthermore, when the output of the second control signal E11 stops, the linear motor 78 is de-energized and turned off (non-operating), but the switch contact 9514 of the lock switch 96 remains in the off (open) state.

[0206] 17(G), the linear motor 1810 of the pump starting device 18 is turned on (operated) again by energization at time t2, and as shown in Fig. 17(H), the switch contact 1822 of the lock switch 1820, which has been held in the on (closed) state, is turned off (open), stopping the transmission of the pump start signal to the disaster prevention receiving panel 12. Furthermore, when the output of the second control signal E11 stops, the linear motor 1810 is de-energized and turned off (non-operating), but the switch contact 1822 of the lock switch 1820 remains in the off (open) state.

[0207] Next, as shown in Figure 17(D), the inspection circuit unit 134 outputs a control signal E12 at time t3, and as shown in Figure 17(I), the transfer switch 140 changes from off (open) to on (closed), supplying DC 48V to the next-stage (second-stage) fire hydrant device 10, and as shown in Figures 17(J) to (R), automatic inspection is performed on the transmitter 16 and pump starting device 18 provided in the second-stage fire hydrant device 10, and automatic inspection is performed sequentially up to the final-stage fire hydrant device 10.

[0208] In addition, the time during which each fire hydrant device 10 transmits a fire notification signal and a pump activation signal to the disaster prevention receiving panel (the time Ton during which the switch contact 9614 of the transmitter 16 and the switch contact 1822 of the pump activation device 18 shown in Figures 17(F) and (H) are held in the on state) is twice the clock period Tc shown in Figure 19.

[0209] [Third embodiment of disaster prevention system for automatic inspection using fR type transmission] Next, a third embodiment of a disaster prevention system that automatically inspects a transmitter and a pump starting device using R-type transmission will be described.

[0210] (f1. Overview of R-type transmission disaster prevention system) First, an outline of the third embodiment of the disaster prevention system for automatic inspection using R-type transmission will be described with reference to Fig. 20 showing an outline of the disaster prevention system using R-type transmission.

[0211] 20, in the third embodiment of the disaster prevention system, for example, four fire hydrant devices 10 are connected in sequence to each of a plurality of signal wirings 14 (signal cables) drawn out in compartment units from a disaster prevention receiving panel 12. Here, the number of fire hydrant devices 10 connected to the signal wirings 14 is arbitrary.

[0212] Furthermore, the signal wiring 14 includes, as in the first embodiment of the disaster prevention system described above, high-voltage signal wiring (signal cable) for commercial AC power supplies and low-voltage signal wiring (signal cable) for specified DC voltage power supplies, and in the embodiment, the low-voltage signal wiring is connected to an operating device equipped with a switch provided on the fire hydrant device 10.

[0213] In the third embodiment of the disaster prevention system, a power supply combined transmission wiring 15 used for R-type transmission is drawn from the disaster prevention receiving panel 12, and all of the fire hydrant devices 10 are connected in sequence to the power supply combined transmission wiring 15. A predetermined power supply voltage, for example, 48 VDC, is supplied through the power supply combined transmission wiring 15, and an inspection control command is transmitted as an inspection instruction signal for issuing an inspection operation instruction during automatic inspection. Note that the signal wiring 14 is a wiring that also includes the power supply combined transmission wiring 15, but in order to clarify the differences from the other embodiments, the power supply combined transmission wiring 15 is shown separately from the signal wiring 14 in Figure 20.

[0214] The fire hydrant device 10 is provided with a transmitter 16 and a pump starting device 18 as operating devices equipped with switches, and the details of the transmitter 16 and the pump starting device 18 are the same as those of the first embodiment of the disaster prevention system described above, and an inspection structure is provided that receives an inspection operation command via R transmission from the inspection control unit 220 of the disaster prevention receiving panel 12 and activates a switch to perform an automatic inspection. The inspection structure of the transmitter 16 and the pump starting device 18 is the same as that of the first embodiment of the transmitter using a non-locking switch shown in Figures 5 to 9, or the second embodiment of the transmitter 16 using a locking switch shown in Figures 12 to 15.

[0215] Furthermore, in order to perform automatic inspections using R-type transmissions from the disaster prevention receiving panel 12, the fire hydrant device 10 is provided with a transmission control unit 160 in which an R-type transmission function has been added to the inspection circuit unit, and a unique address is set for the transmission control unit 160 of the fire hydrant device 10. As a result, during automatic inspections, the inspection control unit 220 of the disaster prevention receiving panel 12 transmits an inspection control command specifying the address of the transmission control unit 160 of the fire hydrant device 10 to be inspected, thereby performing the automatic inspection.

[0216] Here, in the first embodiment in which the transmitter 16 and the pump starting device 18 are equipped with a non-lock switch, the inspection control unit 220 of the disaster prevention receiving panel 12 transmits an inspection control command sequentially specifying the addresses of the transmission control units 160 of the fire hydrant devices 10 to be inspected, and performs automatic inspections of each fire hydrant device 10 sequentially.

[0217] In contrast, in the second embodiment in which the transmitter 16 and the pump starting device 18 are equipped with a lock switch, the inspection control unit 220 of the disaster prevention receiving panel 12 performs automatic inspection of each fire hydrant device 10 in sequence by sending an inspection control command twice with a predetermined time interval between them, sequentially specifying the address of the transmission control unit 160 of the fire hydrant device 10 to be inspected.

[0218] (f2. Circuit configuration of transmitter and pump starter) Next, the circuit configuration of the transmitter and pump starting device provided in the fire hydrant device will be explained. In this explanation, reference will be made to Fig. 21, which shows the circuit configuration of the transmitter and pump starting device provided in the disaster prevention system of the third embodiment. Note that Fig. 21 shows the detailed circuit configuration of one fire hydrant device, and omits the circuit configurations of other fire hydrant devices that have basically the same configuration, showing only the block diagram of the fire hydrant device.

[0219] As shown in Figure 21, four fire hydrant devices 10 are connected to one signal wiring 14 drawn out from the disaster prevention receiving panel 12. The signal wiring 14 includes a transmitter line 110, a response line 112, a pump starting line 114, a power supply transmission line 1500, and a common line 118 shared by these signal lines, in order to perform R-type transmission between the disaster prevention receiving panel 12 and the transmitter 16 and pump starting device 18 provided in the fire hydrant device 10.

[0220] The fire hydrant device 10 shown in FIG. 21 is an example of the first embodiment using a non-lock switch, and includes a non-lock switch 95 in the transmitter 16 and a non-lock switch 1812 in the pump starting device 18.

[0221] The non-lock switch 95 of the transmitter 16 has a switch contact 9514 connected between the transmitter line 110 and the common line 118, and an interlock switch contact 9516 connected between the response line 112 and the common line 118 together with the response lamp 38. When the transmitter 16 is operated, the operation is the same as in the first embodiment of the disaster prevention system described above.

[0222] Furthermore, the non-lock switch 1812 of the pump starting device 18 has a switch contact 1814 connected between the pump starting line 114 and the common line 118, and a switch contact 6010 of the pump start interlocking device 60 is connected in parallel to the switch contact 1814 of the pump starting device 18. The operation when the pump starting device 18 is operated is also the same as in the first embodiment of the disaster prevention system described above.

[0223] In addition, the fire hydrant device 10 is provided with a transmission control unit 160 for automatically inspecting the transmitter 16 and the pump starting device 18. The transmission control unit 160 is connected between the power supply transmission line 1500 and the common line 118, and is equipped with inspection drive switches 162, 164.

[0224] The transmitter 16 is provided with a linear motor (DM) 78 for performing automatic inspection, and the linear motor 78 is connected between the power supply transmission line 1500 and the common line 118 via an inspection drive switch 162. The pump starting device 18 is provided with a linear motor (DM) 1810 for performing automatic inspection, and the linear motor 1810 is connected between the power supply transmission line 1500 and the common line 118 via an inspection drive switch 164.

[0225] (f3. Automatic inspection of transmitters with non-locking switches and pump starters) Next, the automatic inspection of the transmitter equipped with a non-locking switch and the pump starting device will be explained with reference to Fig. 22, which is a time chart showing the automatic inspection operation of the transmitter equipped with a non-locking switch and the pump starting device in the disaster prevention system of the third embodiment.

[0226] The transmission control unit 160 operates using DC 48V supplied between the power supply transmission line 1500 and the common line 118, and when it receives an inspection control command specifying its own address from the inspection control unit 220 of the disaster prevention receiving panel 12 via the power supply transmission line 1500 at time t1 as shown in Figure 22(A), it outputs a control signal E1 at time t2 as shown in Figure 22(B) to turn on (close) the inspection drive switches 162, 164 for a predetermined time, and as shown in Figure 22(C) and (D), the linear motors 78, 1810 turn on (operate), and the drive shaft presses the switch knobs of the non-lock switches 95, 1812, changing the switch contacts 9514, 1814 of the non-lock switches 95, 1812 from off (open) to on (closed), causing a fire alert signal and a pump start signal to be sent to the disaster prevention receiving panel 12.

[0227] Next, as shown in Figure 22(B), at time t3, the output of the control signal E1 is stopped and the inspection drive switches 162, 164 are turned off (open), and as shown in Figures 22(C) and (D), the linear motors 78, 1810 are turned off (non-operating), the switch contacts 9514, 1814 of the non-lock switches 95, 1812 are turned off (open), and the transmission of the fire alarm signal and pump start signal to the disaster prevention receiving panel 12 is stopped.

[0228] (f4. Automatic inspection of transmitters with lock switches and pump starters) Next, the automatic inspection of the transmitter equipped with a lock switch and the pump starting device will be explained with reference to Fig. 23, which is a time chart showing the automatic inspection operation of the transmitter equipped with a lock switch and the pump starting device in the disaster prevention system of the third embodiment.

[0229] Instead of a non-lock switch, if a lock switch 96 is provided on the transmitter 16 and a lock switch 1820 is provided on the pump starting device 18, as in the disaster prevention system of the second embodiment described above, the inspection control unit 220 of the disaster prevention receiving panel 12 will perform control to send an inspection control command specifying the same address twice, with a predetermined time interval between each.

[0230] Therefore, as shown in Figure 23(A), when the transmission control unit 160 receives the first inspection control command specifying its own address from the inspection control unit 220 of the disaster prevention receiving panel 12 via the power supply combined transmission line 1500 at time t1, as shown in Figure 23(B), it outputs the first control signal E1 at time t2 to turn on (close) the inspection drive switches 162, 164 for a predetermined time, and as shown in Figures 22(C) and (D), the linear motors 78, 1810 turn on (operate) and the drive shaft unit presses the switch knobs of the lock switches 96, 1820, changing the switch contacts 9614, 1822 of the lock switches 96, 1820 from off (open) to on (closed), causing a fire alert signal and a pump start signal to be transmitted to the disaster prevention receiving panel 12. Also, as shown in Figure 23(B), at time t3, the output of the first control signal E1 stops, the inspection drive switches 162, 164 turn off (open), and the linear motors 78, 1810 turn off (non-operating), but the switch contacts 9614, 1822 of the lock switches 96, 1820 remain in the on (closed) state.

[0231] Next, as shown in Figure 23(A), when a second inspection control command specifying its own address is received from the inspection control unit 220 of the disaster prevention receiving panel 12 via the power supply combined transmission line 1500 at time t4, as shown in Figure 23(B), a second control signal E1 is output at time t4 to turn on (close) the inspection drive switches 162, 164 for a predetermined time, and as shown in Figures 22(C) and (D), the linear motors 78, 1810 are turned on (operated) again, and the switch contacts 9614, 1822 of the lock switches 96, 1820 which hold the drive shaft in the on (closed) state are turned off (open), and the transmission of the fire alert signal and pump start signal to the disaster prevention receiving panel 12 is stopped. Also, as shown in Figure 23(B), at time t5, the output of the second control signal E1 stops, the inspection drive switches 162, 164 turn off (open), and the linear motors 78, 1810 turn off (non-operating), but the switch contacts 9614, 1822 of the lock switches 96, 1820 remain in the off (open) state.

[0232] As another embodiment of the automatic inspection of the transmitter 16 equipped with a lock switch and the pump starting device 18, the configuration of the inspection circuit unit 134 shown in Fig. 18 may be applied to the transmission control unit 160, and when an inspection control command specifying its own address is received from the disaster prevention receiving panel 12, a first control signal E1 and a second control signal E1 may be output after a predetermined time interval, thereby enabling the automatic inspection to be performed in the same way. By utilizing the configuration of the inspection circuit unit 134, the disaster prevention receiving panel 12 only needs to send an inspection control command specifying addresses sequentially to each hydrant device 10 once for the automatic inspection, making it possible to simplify the command transmission process.
