Opening / closing mechanism and opening / closing mechanism control method

Abstract

To open an opening in a short time using a hydraulic release device for a shutter after a power failure when two actuator devices are installed for one frontage (opening) of a structure skeleton.SOLUTION: In the case of an opening / closing body system with two opening / closing devices installed for one frontage, it is necessary to open (fully or half) both opening / closing devices in order to allow the firefighters to enter a building. In such a case, the system should be controlled so that neither of the two opening / closing devices is fully closed. When closing an opening in which two opening / closing devices are installed, only one of the devices should be fully closed, and the other should be either fully open or half open so that it is not fully closed. This allows the opening to be opened (to the fully-open or half-open state) in a short time after a power failure using one hydraulic relief device for shutters, so that firefighters can quickly enter through the opening.SELECTED DRAWING: Figure 4

Description

Technical Field

[0001] The present invention relates to an opening / closing body device and an opening / closing control method configured to partition an opening of a structure body including buildings such as buildings, factories, warehouses, etc. using an opening / closing body such as a shutter, and particularly relates to an opening / closing body system and an opening / closing control method capable of supplying power to a plurality of opening / closing body devices via a hydraulic release device.

Background Art

[0002] Opening / closing body devices such as shutter curtains are installed at openings of structure bodies including buildings such as houses, buildings, factories, warehouses, garages, etc., window parts, or openings and bays of internal passages and spaces, and the opening / closing body is moved to open and close the opening and bay. This opening / closing body device is configured to close the entire opening by feeding out and lowering the opening / closing body from the upper part of the opening. Such opening / closing body devices often perform the opening / closing operation of the opening / closing body electrically. Examples of electrically operated opening / closing body devices include electric shutter devices, electric door devices, electricawning devices, etc.

[0003] Among such electrically operated opening / closing body devices, there are those equipped with a hydraulic release device configured to operate the opening / closing body device electrically to open the opening / closing body extremely by connecting a fire hose of the fire department to a water supply port (water delivery port) and discharging water even during a power outage due to a fire. As an opening / closing body device equipped with such a hydraulic release device, the one described in Patent Document 1 is known.

Patent Document 1

[0005] Some structural elements consist of windowless floors. Generally, on windowless floors, one opening or closing device, such as a shutter, is installed for each opening. In some cases, two opening or closing devices may be installed for each opening, such as a sheet shutter that can be opened and closed quickly during the day and a steel shutter with higher security at night.

[0006] In a system where two opening / closing devices are installed for each opening, firefighters need to open both devices in order to enter the building. In order to open both opening / closing devices, it is necessary to either install two hydraulic release devices for each opening / closing device, install one large hydraulic release device with the capacity to open both simultaneously, or install hydraulic release devices that can output to both opening / closing devices alternately.

[0007] However, these methods have the following problems: Installing two hydraulic pressure release devices doubles the cost and installation space required. Installing one large hydraulic pressure release device increases the size of the device due to its larger capacity, thus increasing costs. When installing hydraulic pressure release devices that can output alternately, the alternating output prevents both devices from raising simultaneously, potentially delaying the release and delaying the entry of firefighters.

[0008] The present invention has been made in view of the above points, and aims to provide an opening / closing system and an opening / closing control method that can open an opening in a short time using a water pressure release device for shutters after a power outage, when two opening / closing devices are installed for one opening (opening) of a structural frame. [Means for solving the problem]

[0009] The first feature of the opening / closing system of the present invention is that the opening / closing system comprises a first opening / closing device that partitions an opening in a structural frame by opening and closing a first opening / closing member from the periphery of the opening, and a second opening / closing device provided adjacent to the first opening / closing device that partitions the opening by opening and closing a second opening / closing member from the periphery of the opening, wherein the opening / closing system is provided with control means for controlling the opening and closing operations of the first and second opening / closing devices so that the first and second opening / closing members of the first and second opening / closing devices do not both become fully closed.

[0010] In a system where two opening / closing devices are installed for a single opening, both devices must be opened (fully open or partially open) to allow firefighters to enter the building. This invention controls the system so that neither opening / closing device can be fully closed when two opening / closing devices are installed for a single opening. That is, when closing an opening with two opening / closing devices, only one of the devices is fully closed, while the other device is kept in a fully open or partially open state to prevent it from being fully closed. As a result, after a power outage, the opening can be opened (fully open or partially open) in a short time using one water pressure release device for the shutter, allowing firefighters to quickly enter through the opening.

[0011] A second feature of the opening / closing system of the present invention is that, in the opening / closing system described in the first feature, the control means supplies power to the first or second opening / closing device, which is in a fully closed state, from an emergency power supply device built into the hydraulic release device during a power outage, thereby opening the first or second opening / closing member. When closing an opening equipped with two opening / closing devices, only one of the devices will be in the fully closed position. By supplying power to the fully closed device to open its components, firefighters can quickly enter the opening.

[0012] A third feature of the switchable body system of the present invention is that, in the switchable body system described in the second feature, when the input power supplies of the first and second switchable body devices are different, the specifications of the output power supply of the emergency power supply device are switched to the specifications of the output power supply corresponding to the input power supply before supplying power. For example, if two switchgear devices with different input power specifications, such as a lightweight single-phase 100V shutter device and a steel three-phase 200V shutter device, are installed close together in the same opening, the specifications of their input power supplies are different. Therefore, the output power specification of the emergency power supply device is matched to the specifications of their input power supplies, and the switchgear device that is in a fully closed state is controlled to open by switching between single-phase 100V and three-phase 200V. This makes it possible to control two switchgear devices with different input power supply specifications using one emergency power supply device. If the emergency power supply device has a built-in inverter circuit, the input power supply specifications are switched by changing the setting parameters. If the power supply output from the emergency power supply device has only one specification, that output is converted to the desired specification output power supply by a transformer and supplied.

[0013] A fourth feature of the switchgear system of the present invention is that, in the switchgear system described in the third feature, the emergency power supply device includes an inverter means configured to supply output power to the different input power supplies of the first and second switchgear devices by performing predetermined processing using a memory that stores in a storage area a dedicated program and data corresponding to the input power supplies of the first and second switchgear devices, and various parameters necessary for the execution of the processing thereof, and reads from the memory the one corresponding to the input power supply from the dedicated program and data and various parameters necessary for the execution of the processing thereof, and switches the output power supply of the inverter means to supply it to the first or second switchgear device. This system, when an emergency power supply unit has a built-in inverter mechanism, reads from memory the input power supply corresponding to the dedicated program, data, and various parameters necessary for its execution, switches the output power supply of the inverter mechanism, and supplies it to the switching drive mechanism.

[0014] The first feature of the opening / closing body control method of the present invention is an opening / closing body control method for controlling the opening and closing operation of an opening / closing body system comprising a first opening / closing body device that partitions an opening by opening and closing a first opening / closing member from the periphery of an opening in a structural frame, and a second opening / closing body device provided adjacent to the first opening / closing body device that partitions an opening by opening and closing a second opening / closing member from the periphery of the opening, wherein the opening and closing operation of the first and second opening / closing body devices is controlled so that the first and second opening / closing members of the first and second opening / closing body devices do not both become fully closed. This invention relates to a method for controlling an opening / closing body, corresponding to the first feature of the opening / closing body system.

[0015] A second feature of the opening / closing control method of the present invention is that, in the opening / closing control method described in the first feature, power is supplied from an emergency power supply built into the hydraulic release device to the first or second opening / closing device which is in a fully closed state during a power outage, thereby opening the first or second opening / closing member. This invention relates to a method for controlling an opening / closing body, corresponding to the second feature of the opening / closing body system.

[0016] A third feature of the switch control method of the present invention is that, in the switch control method described in the second feature, when the input power supplies of the first and second switch devices are different, the specifications of the output power supply of the emergency power supply device are switched to the specifications of the output power supply corresponding to the input power supply before supplying power. This invention relates to a method for controlling an opening / closing body that corresponds to the third feature of the opening / closing body system.

[0017] The fourth feature of the opening / closing control method of the present invention is that, in the opening / closing control method described in the third feature, the emergency power supply device uses a memory that stores a dedicated program, data, and various parameters necessary for executing the processing corresponding to the input power supplies of the first and second opening / closing body devices in a storage area, and executes predetermined processing to supply output power to different input power supplies of the first and second opening / closing body devices. The inverter means is configured so that the output power of the inverter means is switched by reading out the one corresponding to the input power supply from the dedicated program, data, and various parameters necessary for executing the processing and supplied to the first or second opening / closing body device. This is an invention of an opening / closing control method corresponding to the fourth feature of the opening / closing body system.

Effects of the Invention

[0018] According to the present invention, when two opening / closing body devices are installed for one bay (opening) of a structure housing, the opening can be opened in a short time using a shutter water pressure release device after a power failure.

Best Mode for Carrying Out the Invention

[0020] A preferred embodiment of the opening / closing system according to the present invention will be described below with reference to the attached drawings. In this embodiment, two shutter devices that open and close vertically will be used as an example of opening / closing devices. Figure 1 is a diagram showing an example of the schematic configuration of two shutter devices according to the present invention. Figure 2 is a schematic diagram of the two shutter devices in Figure 1 viewed from the side. In Figure 1, opening / closing devices 10a and 10b are shutter devices that open and close the same opening vertically. Opening / closing device 10a is a heavy steel shutter curtain with high security features mainly used at night, and is a shutter device that uses a three-phase 200V input power supply. Opening / closing device 10b is a lightweight shutter curtain that can be opened and closed at high speed mainly used during the day, and is a shutter device that uses a single-phase 100V input power supply.

[0021] The opening and closing devices 10a and 10b are installed in the same opening of the building. For example, the opening where the opening and closing device 10a is installed is approximately 3 m high and has a travel speed of 3 m / min. The travel speed of the opening and closing device 10b is 6 m / min. The opening and closing devices 10a and 10b basically consist of shutter cases 11a and 11b, shutter curtains 12a and 12b, guide rails 13a, 13b, 14a and 14b, winding shafts 15a and 15b, chains 16a and 16b, motors 17a and 17b, control devices 18a and 18b, operating switches 19a and 19b, and obstacle detectors 185a and 185b. An emergency power supply device 20 and a water pressure switch 30 are provided in common for both opening and closing devices 10a and 10b. In other words, the emergency power supply unit 20 and the water pressure switch 30 constitute a water pressure release device for a shutter equipped with a dual-switching function.

[0022] These opening and closing devices 10a and 10b are normally controlled to open and close separately by driving the motors 17a and 17b, which are the opening and closing mechanisms, in response to the operation of the operating switches 19a and 19b. Furthermore, these opening and closing devices 10a and 10b maintain the open state in which the shutter curtains 12a and 12b are wound onto the winding shafts 15a and 15b by a mechanical holding mechanism (not shown). If an emergency signal BS indicating the occurrence of a fire or the like is input to the control device 18a from the outside while the opening is open, the holding mechanism releases the open state, and the steel shutter curtain 12a descends naturally by its own weight to function as a fire shutter, automatically closing the opening.

[0023] Guide rails 13a, 13b, 14a, and 14b are installed on both ends of the building opening so as to be in contact with both ends of the shutter curtains 12a and 12b, and are made of metal members or equivalent members having a U-shaped guide groove that extends from the lintel to the floor. The shutter curtains 12a and 12b move up and down along the guide grooves of these guide rails 13a, 13b, 14a, and 14b, thereby opening and closing the opening.

[0024] The winding shafts 15a and 15b are rotatably mounted on both ends of the shutter cases 11a and 11b, and wind up and unwind the shutter curtains 12a and 12b. Chains 16a and 16b connect the driving sprockets on the rotating shafts of the motors 17a and 17b to the driven sprockets on the rotating shafts of the winding shafts 15a and 15b. Therefore, the rotational driving force of the motors 17a and 17b is transmitted to the winding shafts 15a and 15b via chains 16a and 16b, and when the motors 17a and 17b rotate, the winding shafts 15a and 15b rotate via chains 16a and 16b, thereby controlling the opening and closing operation of the shutter curtains 12a and 12b.

[0025] Motors 17a and 17b are equipped with a position detection device (not shown) for detecting their rotational position, i.e., the open / closed position and state of the shutter curtains 12a and 12b. This position detection device consists of a pulse-generating rotary encoder or the like. Pulse signals corresponding to the rotation of motors 17a and 17b are output to control devices 18a and 18b, so the rotational position of motors 17a and 17b and the position of the closed end of the shutter curtains 12a and 12b at the opening are calculated by the control devices 18a and 18b based on the generation of these pulses.

[0026] The control devices 18a and 18b are microcomputer-based and are supplied with power from the AC power line via the emergency power supply 20. The control devices 18a and 18b control the rotation of motors 17a and 17b based on control signals corresponding to the operation status of each operation button on the operation switches 19a and 19b, as well as signals from position detection devices provided on motors 17a and 17b and signals from protectors. The control device 18a releases the holding mechanism based on the emergency signal BS.

[0027] The operation switches 19a and 19b function as control switches corresponding to opening and closing operations, and each has an upward (open) button 19a1, 19b1, a stop (stop) button 19b1, 19b2, and a downward (close) button 19c1, 19c2, respectively, and output control signals to the control devices 18a and 18b according to the operation status of each of these buttons. Although not shown in the figures, the operation switch 19a also includes an activation switch that outputs an activation signal to activate the automatic closing function, a recovery switch that outputs a recovery signal to release the signal from the activation switch and restore the automatic closing function, a start button that outputs a start signal to start the emergency power supply 20, and a release switch to release the alarm signal output from the emergency power supply 20.

[0028] The emergency signal BS is a 24V signal supplied from an external control room or similar location in the event of an emergency such as a fire, and is input to a safety interlock relay (not shown in Figure 1) within the control device 18a. In addition to or instead of the input of the emergency signal BS from the outside, a temperature sensor may be installed inside the shutter case 11a, near the opening of the lintel section, i.e., in the area where the shutter curtain 12a moves up and down. This temperature sensor may consist of a high-temperature bimetallic thermostat with an automatic reset B contact that is normally ON and turns OFF when the contact reaches a predetermined temperature (any temperature in the range of 100 to 300 degrees Celsius). When the contact opens, a signal indicating that a fire or other emergency has occurred is output to the emergency power supply 20, and the emergency power supply 20 may output a signal equivalent to the emergency signal BS.

[0029] Obstacle detectors 185a and 185b have transmitters installed on the lower ends (seat plates) of the shutter curtains 12a and 12b. When an obstacle is detected, they transmit a detection signal corresponding to the movement of the built-in seat plate switch to the control devices 18a and 18b. When the seat plate switch returns to its original position after the obstacle is removed, a return signal is transmitted. The transmission of signals from the transmitters of obstacle detectors 185a and 185b to the control devices 18a and 18b is not limited to the wired method shown in the figure; a wireless method powered by batteries may also be used. Alternatively, a seat plate switch that moves upon contact with an obstacle may be provided on the lower ends of the shutter curtains 12a and 12b, and the force of the seat plate's movement upon contact with an obstacle may press a tape switch installed along the height direction of the guide rail. Alternatively, a detection signal may be output via a wire from the tape switch to the control means. In addition, a light-emitting and receiving sensor such as a photoelectric tube or LED may be provided in the opening to detect obstacles non-contactually using image recognition or the like.

[0030] The water pressure switch 30 is activated when a fire hose is connected to a water inlet (not shown) located outside the building during a fire, and water is supplied (injected) from there, and the water pressure (force of the water flow) reaches a predetermined range. The switch outputs an activation signal to the emergency power supply unit 20. The emergency power supply unit 20, upon receiving this activation signal, outputs a relay signal to the obstacle detection device control panel 184a shown in Figure 3. The water pressure range that activates the water pressure switch 30 is set appropriately considering the expected water discharge capacity of the fire brigade. A fire hose is connected to the water inlet during a fire. The water supplied from the water inlet is drained through a drain outlet (not shown) via the water pressure switch 30.

[0031] Figure 3 is a schematic diagram of the circuit configuration of the control system constituting the switch / open device according to the present invention. The control device 18a is controlled by a microcomputer and comprises a switch / open device control device 181a, a safety interlock relay 182a, an automatic closing device 183a, and an obstacle detection device control panel 184a. It processes signals input from the operation switch 19a, obstacle detector 185a, water pressure switch 30, etc., as well as power and various signals output from the emergency power supply device 20, to control the motor 17a and the automatic closing device 183a. Note that the control device 18b does not have an automatic closing device and has the same configuration as the control device 18a, so the control device 18a will be described, and the illustration and description of the control device 18b will be omitted.

[0032] The switchgear control device 181a operates using AC voltage supplied via the power line, which is switched by the emergency power supply 20 upon input of an input disconnection signal indicating a disconnection of commercial power from the power line. In other words, normally, the motor 17a is supplied with power from the commercial power supply, but in the event of an emergency such as a power outage, when the power supply from the commercial power supply is interrupted, the switchgear control device 181a receives AC voltage from the output circuit 204 of the emergency power supply 20. Some switchgear control devices 181a also incorporate an inverter circuit to convert the DC or AC voltage input from the power line into a power source according to the motor 17a's rating. The inverter circuit has a memory that stores a dedicated program, data, and various parameters necessary for processing and execution, and is configured to output an output power according to the specifications of the respective program and parameters when the start button is operated or when an operating signal is input from the water pressure switch. This inverter circuit receives a signal indicating shutter position information from the position detection device 172a provided on the motor 17a and controls the conversion operation from DC voltage to AC voltage based on this information. Note that in Figure 3, the connections of power lines other than the control device 18a are not shown.

[0033] The hazard prevention interlock relay 182a, upon receiving an activation signal from the emergency signal BS or the operation switch 19a, outputs power (e.g., DC24V) from the commercial power supply or the emergency power supply unit 20 to activate the automatic closing device 183a. Normally, the hazard prevention interlock relay 182a outputs power using the commercial power supply, but in the event of a power outage, it outputs a DC24V signal to the automatic closing device 183a using power from the emergency power supply unit 20.

[0034] The automatic closing device 183a operates by releasing the holding mechanism 171a in response to a 24V DC signal supplied via the safety interlock relay 182a, causing the rolled-up shutter curtain 12a to descend by its own weight and automatically closing the opening. The automatic closing device 183a is configured to extend a pressing actuation member by the rotational force of a motor when a 24V DC signal is supplied. This pressing actuation member is positioned to press the operating lever of the holding mechanism 171a with its protruding end. In an emergency, the automatic closing device 183a may also lower the shutter curtain 12a by its own weight in response to the operation of an emergency closing button provided on the operation switch 19a. The automatic closing device 183a releases the holding mechanism 171a while a 24V DC signal is supplied from the safety interlock relay 182a, but if there is an obstacle detection signal from the obstacle detection device control panel 184a, it returns the holding mechanism 171a to its original position during that time. Furthermore, some systems reset the holding mechanism 171a if the power supply (DC 24V signal) from the safety interlock relay 182a is lost.

[0035] The emergency power supply unit 20 is controlled by a microcomputer and comprises a power switching circuit 201, a charging circuit 202, a backup power supply (battery) 203, and an output circuit 204. The power switching circuit 201 supplies commercial AC power supplied via the power line to the switchgear control device 181a and also supplies power to the charging circuit 202. When the power switching circuit 201 detects that the commercial AC power supplied from the power line has been interrupted, it outputs an input interruption signal to the output circuit 204 indicating that the commercial power input has been interrupted. The charging circuit 202 charges the backup power supply (battery) 203 using the power supplied from the power switching circuit 201. The backup power supply (battery) 203 consists of a lithium-ion rechargeable battery or other batteries (including power supplies that are used up, such as dry cell batteries, in addition to rechargeable batteries), and supplies power to the switchgear control device 181a, etc., via the output circuit 204 during a power outage.

[0036] The output circuit 204 receives an input disconnection signal from the power switching circuit 201 indicating a disconnection of the commercial power supply, and converts the DC voltage from the backup power supply 203 into a predetermined AC voltage using an inverter circuit according to the specifications of the connected external equipment. In other words, the output circuit 204 has a built-in inverter circuit and is capable of supplying AC voltage according to the specifications of the external equipment. The inverter circuit has a built-in internal memory that operates when AC voltage is generated, so the emergency power supply device 20 constantly performs a test (such as a Read / Write test or March-C test) to determine whether or not there is an abnormality in this internal memory. Normally, the switchgear control devices 181a and 181b are supplied with power from the commercial power supply, but in the event of an emergency such as a power outage, when the power supply from the commercial power supply is interrupted, the inverter circuit of the output circuit 204 converts the DC voltage from the backup power supply 203 into a predetermined AC voltage and supplies it to the switchgear control devices 181a and 181b.

[0037] As described above, the switchgear 10a uses a single-phase 100V input power supply, and the switchgear 10b uses a three-phase 200V input power supply. Therefore, the output circuit 204 writes pattern data or parameters for the operation of an inverter circuit that converts DC voltage to single-phase 100V into its internal memory, converts the DC voltage to a single-phase 100V AC voltage, and supplies it to the switchgear control device 181a of the switchgear 10a. When the switching operation of the switchgear 10a is completed, the output circuit 204 writes pattern data or parameters for the operation of an inverter circuit that converts DC voltage to three-phase 200V into its internal memory, converts the DC voltage to a three-phase 200V AC voltage, and supplies it to the switchgear control device 181b of the switchgear 10b.

[0038] Figure 4 is a flowchart illustrating an example of the processing performed by the two shutter devices shown in Figures 1 to 3. Below, an example of the coordinated operation performed by the open / close control devices 181a and 181b will be explained using this flowchart. In this embodiment, the open / close control devices 181a and 181b of the two shutter devices 10a and 10b work together to control one of the two shutter devices 10a and 10b to always be in the open state. That is, the open / close control devices 181a and 181b of the two shutter devices 10a and 10b work together to control the two shutter devices 10a and 10b to not be in the closed state simultaneously.

[0039] In step S40, the switchgear control devices 181a and 181b perform the power-on processing, i.e., the initialization process. In step S41, the opening / closing control device 181a fully opens the shutter curtain 12a of the opening / closing device 10a, and the opening / closing control device 181b fully closes the shutter curtain 12b of the opening / closing device 10b. The two opening / closing devices 10a and 10b in Figure 2 correspond to this state.

[0040] In step S42, the switchgear control devices 181a and 181b determine whether the signal they received is a stop signal corresponding to the operation of the stop switches 19a2 and 19b2 of the operation switches 19a and 19b. If a stop signal is received (yes), the device proceeds to the next step S43; otherwise, it proceeds to step S45. In step S43, it is determined whether the current shutter curtains 12a and 12b are in opening / closing operation or not (stopped). If they are in opening / closing operation (yes), the process proceeds to the next step S44; if they are stopped (no), the process returns to step S42. In step S44, since the shutter curtains 12a and 12b are in the process of opening and closing, their operation is stopped and the process returns to step S42. Here, the movement of the shutter curtains 12a and 12b during the opening operation is considered forward movement, and the movement during the closing operation is considered reverse movement.

[0041] In step S45, the switchgear control devices 181a and 181b determine whether the received signal is an open signal corresponding to the operation of the open switches 19a1 and 19b1 of the operation switches 19a and 19b. If an open signal is received (yes), the device proceeds to the next step S46; otherwise, it proceeds to step S28. In step S46, it is determined whether the current shutter curtains 12a and 12b are in the closing operation (opening operation or stopped). If they are in the closing operation (yes), the process proceeds to the next step S26; if they are in the opening operation or stopped (no), the process proceeds to step S47.

[0042] In step S47, since it was determined in step S46 that the closing operation was in progress, the closing operation is stopped, the opening operation is started after the closing operation is stopped, and the process proceeds to the next step S49. In step S48, since it was determined in step S46 that the opening operation was in progress or stopped (no), if the opening operation was in progress, the opening operation is continued; if it was stopped at an intermediate position, the opening operation is resumed; and if it was stopped at the fully open position, nothing is done and the process proceeds to step S49.

[0043] In step S49, it is determined whether the shutter curtains 12a and 12b are fully open or not. If they are fully open (yes), the process proceeds to the next step S50. If they are not fully open (no), this determination is repeated until the system stops in the fully open position. In step S50, the opening operation is stopped and the process returns to step S42.

[0044] In step S51, the switchgear control devices 181a and 181b determine whether the received signal is a closing signal corresponding to the operation of the closing switches 19a3 and 19b3 of the operation switches 19a and 19b. If it is a closing signal (yes), proceed to the next step S52; otherwise, return to step S42. In step S52, it is determined whether the shutter curtains 12a and 12b are fully closed or not. If they are not fully closed (no), the process proceeds to the next step S53; if they are fully closed (yes), the process returns to step S42.

[0045] In step S53, it is determined whether the other shutter curtains 12a and 12b are fully open or not. If they are not fully open (no), the process proceeds to step S54; if they are fully open (yes), the process proceeds to step S55. In step S54, a closing signal is sent to the other open / close control devices 181a and 181b, causing the other shutter curtains 12a and 12b to close. In this way, the open / close control devices 181a and 181b of the two shutter devices 10a and 10b work together to control the two shutter devices 10a and 10b so that they do not close simultaneously.

[0046] In step S55, it is determined whether the current shutter curtains 12a and 12b are in the opening operation (closing operation or stopped). If they are in the opening operation (yes), the process proceeds to step S57; if they are in the closing operation or stopped (no), the process proceeds to step S56. In step S56, if the closing operation is in progress, the closing operation continues; if it is stopped, the closing operation starts and the process returns to step S52. In step S57, since the opening operation is in progress, the opening operation is stopped, the closing operation is started after the opening operation is stopped, and the process returns to step S52. In the case of automatic closing, steps S52 to S54 are executed to open the shutter curtain 12b, which is in the fully closed state.

[0047] Figure 5 is a flowchart illustrating an example of the processing performed by the emergency power supply unit in Figure 1 after a power outage. The emergency power supply unit 20 starts processing after a power outage occurs, but the details of the processing performed when an activation signal is received from the water pressure switch 30 immediately after the power outage will be explained below.

[0048] In step S60, the power switching circuit 201 outputs an input interruption signal to the output circuit 204, indicating that the commercial power input has been interrupted due to the power outage. In step S61, it is determined which of the shutter devices 10a and 10b is in the fully closed state. If shutter device 10a is in the fully closed state, the process proceeds to step S62. If shutter device 10b is in the fully closed state, the process proceeds to step S65.

[0049] In step S62, since the shutter device 10a is in the fully closed state, parameters for operating the inverter circuit that converts the DC voltage to three-phase 200V are set in the internal memory of the output circuit 204. As a result, the inverter circuit of the output circuit 204 becomes capable of outputting a three-phase 200V AC voltage corresponding to the input power supply of the switchgear device 10a.

[0050] In step S63, the inverter circuit of the output circuit 204 outputs a three-phase 200V AC voltage to the opening / closing device 10a, which is the first shutter, and performs an emergency opening process corresponding to the operating signal from the water pressure switch 30. In step S64, it is determined whether the opening / closing device 10a, which is the first shutter, has been fully opened by the emergency opening process. If it is fully open (yes), the process is terminated. If it is not fully open (no), the emergency opening process for the opening / closing device 10a in step S63 is continued.

[0051] In step S65, since the shutter device 10b is in the fully closed state, parameters for operating the inverter circuit that converts the DC voltage to single-phase 100V are set in the internal memory of the output circuit 204. As a result, the inverter circuit of the output circuit 204 becomes capable of outputting a single-phase 100V AC voltage corresponding to the input power supply of the switchgear device 10b. In step S66, the inverter circuit of the output circuit 204 outputs a single-phase 100V AC voltage to the opening / closing device 10b, which will be the second shutter, and performs an emergency opening process corresponding to the operating signal from the water pressure switch 30. In step S67, it is determined whether the opening / closing device 10b, which is the second shutter, has been fully opened by the emergency opening process. If it is fully open (yes), the process is terminated; otherwise, the emergency opening process for the opening / closing device 10b in step S66 is continued.

[0052] In the above-described embodiment, the case where the input power supplies for the switchgear devices 10a and 10b are different was explained, but the input power supplies may also be the same. In the above-described embodiment, a shutter curtain that extends in an up-and-down manner was used as an example, but the same method can be applied to shutter-like opening and closing members that extend in a horizontal sliding manner or horizontally. Furthermore, the method can be applied to opening and closing devices such as shutter devices, window shutter devices, blind devices, roller screen devices, curtain devices, sliding door devices, movable partition devices, awning devices, waterproof panel devices, etc.

[0053] In the above-described embodiment, the case in which the inverter circuit 204 outputs an output power supply with different specifications by switching parameters over time was explained. However, if the specifications of the power supply output from the inverter circuit 204 are only one type, the output may be converted to an output power supply with the desired specifications by a transformer before being supplied.
