Description

Technical Field

[0001] The present invention relates to a facility management system and a facility management method.

Background Art

[0002] Facilities such as mechanical parking lots are equipped with electric facilities such as automatically opening and closing doors and lift devices for transporting stored items to different floors. These facilities are installed with sensors for acquiring information indicating the operating state or the ambient environmental state, etc. In a management system for managing these facilities, an operation control unit for performing operation control of the facilities monitors the detection status by these sensors, and when a predetermined detection state is reached, outputs a drive stop signal to a power control unit for driving the operation mechanism of the facilities, thereby performing safe operation.

[0003] For example, in a mechanical parking lot, when the opening and closing door at the entrance / exit is in the open state, users can enter and exit the parking lot. Therefore, in order to ensure the safety of users, it is desirable to stop the operation of the facilities in the parking lot.

[0004] In order to cope with this, when the opening and closing door of a mechanical parking lot is fully open, there is a technique for cutting off the power supply to the operation mechanism of the facilities (for example, Patent Document 1). By performing such processing, when the opening and closing door is fully open and a user enters the mechanical parking lot, it is possible to prevent the lift device from operating and contacting the user, or the opening and closing door from accidentally closing and confining the user inside the mechanical parking lot.

Summary of the Invention

Problems to be Solved by the Invention

[0006] On the other hand, since users can enter and exit the parking lot even while the doors of the entrance and exit of the mechanical parking lot are in the process of opening or closing, it is necessary to ensure the safety of users during this period as well.

[0007] However, the aforementioned technology has the problem that while it can guarantee user safety while the door is fully open, it cannot stop the operation of equipment other than the door while the door is opening or closing.

[0008] The present invention has been made in view of the above circumstances, and aims to provide a facility management system and a facility management method that can ensure the safety of users during the opening and closing operation of an opening and closing door in a facility equipped with electric equipment including an opening and closing door. [Means for solving the problem]

[0009] To achieve the above objective, the present invention provides a facility management system comprising: a power control unit for driving the operating mechanism of equipment including opening and closing doors within a facility; an operation control unit for controlling the power control unit; and a safety controller that, while the opening and closing operation of the opening and closing doors is controlled by the operation control unit, restricts the operation of at least one of the other pieces of equipment by the power control unit, and while the fully open state of the opening and closing doors is maintained, restricts the operation of at least one of the pieces of equipment including the opening and closing doors by the power control unit.

[0010] Furthermore, the equipment management method of the present invention includes a power control unit that drives the operating mechanism of equipment including an opening and closing door within a facility, and an operation control unit that controls the power control unit. A safety controller, which is communicably connected to these units, restricts the operation of at least one of the other pieces of equipment by the power control unit while the opening and closing operation of the opening and closing door is controlled by the operation control unit, and restricts the operation of at least one of the pieces of equipment including the opening and closing door by the power control unit while the fully open state of the opening and closing door is maintained. [Effects of the Invention]

[0011] According to the equipment management system and equipment management method of the present invention, in relation to a facility equipped with electric equipment including an opening and closing door, it is possible to ensure the safety of users during the opening and closing operation of the opening and closing door.

[Modes for carrying out the invention]

[0013] Hereinafter, as an embodiment of the present invention, an equipment management system for managing a mechanical parking lot P, which is a facility having a plurality of electric equipment including an opening and closing door, will be described with reference to the drawings. In the mechanical parking lot P, a plurality of electric equipment including an opening and closing door are installed.

[0014] 《First Embodiment》 〈Configuration of the Equipment Management System According to the First Embodiment〉 FIG. 1 is an overall view showing the configuration of an equipment management system 1A according to the first embodiment of the present invention. The equipment management system 1A manages the equipment in the mechanical parking lot P.

[0015] The equipment management system 1A includes an opening and closing door 10 which is the first equipment installed in the mechanical parking lot P, a turning device 20 which is the second equipment, and a lift device 30 which is the third equipment, a power control unit 40A, an operation reception unit 50, an operation control unit 60, an emergency notification unit 70, and a safety controller 80A. The equipment in the mechanical parking lot P other than the opening and closing door 10 is not limited to the turning device and the lift device, and any electric device may be used. Also, the number of equipment other than the opening and closing door 10 is not limited to two, and may be one or three or more.

[0016] The opening and closing door 10 is a door installed at the entrance and exit of the mechanical parking lot P, and has a first power unit 11, an open limit detection sensor 12, and a first closed limit detection sensor 13 (hereinafter simply referred to as "closed limit detection sensor 13"). The first power unit 11 is a mechanism for opening and closing the opening and closing door 10.

[0017] The open limit detection sensor 12 is an operation sensor that detects that the opening and closing door 10 is fully opened when the opening and closing door 10 reaches a predetermined door opening stop position. The close limit detection sensor 13 is an operation sensor that detects that the opening and closing door 10 is fully closed when the opening and closing door 10 reaches a predetermined door closing stop position. The open limit detection sensor 12 and the close limit detection sensor 13 are, for example, sensors that physically detect that the opening and closing door 10 has reached a predetermined position, sensors that detect electromagnetically without contact, sensors that detect by analyzing imaging information obtained by photographing the opening and closing door 10, sensors that detect by measuring the moving distance of the opening and closing door 10 due to the opening and closing operation, sensors that detect by measuring the position of the opening and closing door 10, and the like.

[0018] The open limit detection sensor 12 and the close limit detection sensor 13 output detection information to the operation control unit 60.

[0019] The turning device 20 includes a second power unit 21 and a safety sensor 22. The second power unit 21 is a mechanism that turns the pallet on which the vehicle is loaded. The safety sensor 22 is a device that performs measurements for monitoring the safety of the operation of the turning device 20.

[0020] The lift device 30 includes a third power unit 31 and a safety sensor 32. The third power unit 31 is a mechanism that raises and lowers the pallet within the mechanical parking lot P and transports it to different floors. The safety sensor 32 is a device that performs measurements for monitoring the safety of the operation of the lift device 30, and is composed of, for example, a limit position detection sensor that detects the maximum position within the operating range of the lift device 30.

[0021] The power control unit 40A is composed of, for example, an inverter, a switch, a PLC (programmable logic controller), etc., and drives or stops the first power unit 11 of the opening and closing door 10, the second power unit 21 of the turning device 20, and the third power unit 31 of the lift device 30 based on signals transmitted from the operation control unit 60 and the safety controller 80A as described later. The power control unit 40A may be installed in duplicate for one power unit to enhance fault tolerance.

[0022] The power control unit 40A and the first power unit 11 of the opening / closing door 10 are connected by a power supply line 91 and a communication line 101. A first switch 911 is installed on the power supply line 91 to switch the connection between the power control unit 40A and the first power unit 11 ON / OFF.

[0023] The power control unit 40A and the second power unit 21 of the slewing device 20 are connected by a power supply line 92 and a communication line 102. A second switch 921 and a third switch 922, which switch the ON / OFF state of the connection between the power control unit 40A and the second power unit 21, are installed on the power supply line 92.

[0024] The power control unit 40A and the third power unit 31 of the lift device 30 are connected by a power supply line 93 and a communication line 103. A fourth switch 931 and a fifth switch 932, which switch the ON / OFF state of the connection between the power control unit 40A and the third power unit 31, are installed on the power supply line 93.

[0025] The power control unit 40A switches the operation of the first power unit 11, the second power unit 21, and the third power unit 31 by, for example, 1) operation switching control by software, 2) operation switching control performed after adjustment of the operating speed by software, or 3) power supply ON / OFF control using a switch. The power control unit 40A may set which of the above 1) to 3) to adopt when controlling the operation of the equipment based on a signal from the operation control unit 60 and when controlling the operation of the equipment based on a signal from the safety controller 80A. Alternatively, the power control unit 40A may set which of the above 1) to 3) to adopt for each piece of equipment whose operation is to be controlled.

[0026] The operation reception unit 50 consists of, for example, an operation panel installed in the mechanical parking lot P or at a remote location, a remote controller or smart device held by the user, and receives information on operations related to the use of the mechanical parking lot P by the user. The operation reception unit 50 may also consist of a terminal that is communicably connected to a remote management device that remotely manages the mechanical parking lot P, and may receive information on operations to operate the equipment in the mechanical parking lot P output from this remote management device. These operations may be performed by the user, or they may be operations instructed by an autonomous mobile device such as an autonomous vehicle or delivery robot, or by an operator remotely controlling a mobile device.

[0027] The operation control unit 60 is composed of, for example, a PLC or a personal computer (PC), and controls the power control unit 40A based on the operation information received by the operation reception unit 50. Furthermore, when the operation control unit 60 detects an abnormality that has occurred in the safety controller 80A, it outputs a stop signal to the power control unit 40A to stop the operation of the equipment.

[0028] The emergency notification unit 70 consists of an emergency button or the like, and when an operation is performed to notify that an emergency or critical situation has occurred, it generates an emergency notification and outputs it to the safety controller 80A. The emergency notification unit 70 may be installed near equipment such as the opening / closing door 10 or the lift device 30, or it may be integrated with the operation reception unit 50 and mounted on the control panel installed in the mechanical parking lot P. Fault tolerance may be enhanced by duplicating the communication path between the emergency notification unit 70 and the safety controller 80A.

[0029] The safety controller 80A consists of a PLC or PC equipped with a self-check function to diagnose the operating status, including abnormalities in the device itself. When the safety controller 80A detects an abnormality occurring in equipment such as the operation control unit 60 connected to the device, or in the safety sensors 22, 32, or the safety controller 80A itself, when it detects an abnormality occurring in the equipment or within the sensors based on sensor signals acquired from these sensors, or when it receives an emergency notification output from the emergency notification unit 70, it outputs a stop signal to the power control unit 40A to stop the operation of the equipment.

[0030] Furthermore, the safety controller 80A, under the control of the operation control unit 60, restricts the operation of the equipment in the mechanical parking garage P by the power control unit 40A while the opening and closing operation of the opening and closing door 10 is in progress.

[0031] Specifically, the safety controller 80A monitors the open / closed state of the second switch 921 and the third switch 922, which are installed on the power supply line 92 connecting the power control unit 40A and equipment other than the open / closed door 10, and the fourth switch 931 and the fifth switch 932, which are installed on the power supply line 93, from the start of the opening operation of the open / closed door 10 controlled by the operation control unit 60 until it is fully closed. If the safety controller 80A detects that any of the switches are in the closed state during monitoring, it executes an emergency stop function to stop the operating mechanism of the equipment in the mechanical parking lot P. In addition, when the safety controller 80A executes the emergency stop function and stops the operating mechanism of the equipment, it sends an abnormal signal to the operation control unit 60. As a result, the operation control unit 60 can display information that the equipment has been emergency stopped on the remote monitoring system or on a display panel provided on the operation reception unit 50.

[0032] Furthermore, the safety controller 80A restricts the operation of the equipment by outputting a stop signal to the power control unit 40A that stops the operation of all equipment while the opening / closing door 10 is maintained in the fully open state. At this time, the restriction may be applied to all equipment in the mechanical parking lot P, or it may be applied only to the opening / closing door 10 and equipment that is pre-configured not to operate simultaneously with the opening / closing door 10 (for example, a lift device, a slewing device, etc.).

[0033] <Operation of the equipment management system according to the first embodiment> This section describes the processes performed by each device in the equipment management system 1A when the opening and closing door 10 in the mechanical parking garage P opens and closes. Figure 2 is a sequence diagram showing the processes performed by each device when the opening and closing door 10 transitions from the closed state to the open state and is fully open.

[0034] In the initial state, the opening / closing door 10 is closed, and the first power unit 11 is stopped. Also, the first switch 911, the second switch 921, the third switch 922, the fourth switch 931, and the fifth switch 932 are open.

[0035] When a user performs an operation to enter a vehicle into the parking lot or to take out a vehicle that is already parked in the parking lot using the operation reception unit 50, the operation reception unit 50 transmits an entry / exit command to the operation control unit 60.

[0036] When the operation control unit 60 receives an entry / exit command from the operation reception unit 50 (YES in S1), it closes the fourth switch 931 and the fifth switch 932 on the power supply line 93. The power control unit 40A supplies power to the lift device 30 via the power supply line 93 and also sends an operation command to the third power unit 31 via the communication line 103.

[0037] Based on the acquired operation signal, the third power unit 31 transports the pallet, which is the carrier for the vehicle to be processed for entry and exit, to the entrance / exit of the mechanical parking lot P. Once the pallet transport operation by the third power unit 31 is completed, the operation control unit 60 opens the fourth switch 931 and the fifth switch 932.

[0038] Next, the operation control unit 60, if necessary, closes the second switch 921 and the third switch 922 on the power supply line 92 to supply power to the slewing device 20, and also sends an operation command to the second power unit 21 via the communication line 102 to rotate the pallet. Once the rotation of the pallet by the second power unit 21 is complete, the operation control unit 60 opens the second switch 921 and the third switch 922. With these operations, the preparation for vehicle entry and exit is complete, and the opening and closing door 10 becomes ready to be opened.

[0039] When the opening / closing door 10 is ready to be opened, the operation control unit 60 sends a notification to the safety controller 80A that the door opening operation has started (S2). When the safety controller 80A receives the notification that the door opening operation has started, it starts monitoring the open / closed status of the second switch 921, the third switch 922, the fourth switch 931, and the fifth switch 932 (S3).

[0040] The operation control unit 60 also transmits a door open command for the opening / closing door 10 to the power control unit 40A (S4). Based on the door open command from the operation control unit 60, the power control unit 40A transmits an operation signal to the first power unit 11 to open the opening / closing door 10 (S5). Based on the operation signal received from the power control unit 40A, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door opening operation (S6).

[0041] The safety controller 80A detects if any of the switches on the power supply line are closed while monitoring the open / closed status of these switches.

[0042] When the safety controller 80A detects that any of the switches are closed, it executes an emergency stop function, thereby stopping the operation mechanism of the entire facility in the mechanical parking garage P. Furthermore, after executing the emergency stop function and stopping the facility's operation mechanism, the safety controller 80A sends an abnormal signal to the operation control unit 60.

[0043] If the door 10 is fully opened while the safety controller 80A is not detecting that the power supply line 92 or 93 has been connected, the door 10 will be fully opened, and the opening limit detection sensor 12 will detect that the door 10 is fully open.

[0044] When the opening limit detection sensor 12 detects that the opening / closing door 10 is fully open, it outputs a detection ON signal to the operation control unit 60. When the operation control unit 60 receives the detection ON signal from the opening limit detection sensor 12 (YES in S7), it sends an operation stop command to the power control unit 40A (S8).

[0045] When the power control unit 40A receives a stop command from the operation control unit 60, it transmits a stop signal to the first power unit 11 (S9). Based on the stop signal received from the power control unit 40A, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S10).

[0046] Furthermore, when the operation control unit 60 receives a detection ON signal from the opening limit detection sensor 12, it notifies the safety controller 80A that the door opening operation has stopped because the opening / closing door 10 has been fully opened (S11).

[0047] Based on a notification received from the operation control unit 60, the safety controller 80A transmits an operation restriction command using the STO (Safe torque off) function to the power control unit 40A (S12). Upon receiving the operation restriction command from the safety controller 80A, the power control unit 40A restricts the operation of the first power unit 11, the second power unit 21, and the third power unit 31 by limiting the power supply to these devices (S13).

[0048] Figure 3 is a sequence diagram showing the processes performed by each device when the door closing operation is performed after the door opening 10 has been fully opened.

[0049] After the door 10 is fully opened, the user performs a door closing operation at the operation reception unit 50 to close the door 10, and the operation reception unit 50 sends a door closing command to the operation control unit 60, or a determination unit (not shown) that automatically determines the timing of the closing operation of the door 10 sends a door closing command to the operation control unit 60, at which point the operation control unit 60 receives this door closing command (YES in S14).

[0050] When the operation control unit 60 receives a door closing command, it sends a notification to the safety controller 80A that the door closing operation has started (S15). When the safety controller 80A confirms that the switch being monitored is not in the closed state, it sends a restriction release command to the power control unit 40A (S16). When the power control unit 40A receives the restriction release command from the safety controller 80A, it releases the operation restrictions on each piece of equipment that were imposed in step S13 (S17).

[0051] The safety controller 80A also transmits an equipment operation permission notification to the operation control unit 60, which authorizes the operation of each piece of equipment (S18). When the operation control unit 60 receives the equipment operation permission notification from the safety controller 80A, it accepts the permission notification (S19) and transmits the door closing command received in step S14 to the power control unit 40A (S20).

[0052] Based on the door closing command from the operation control unit 60, the power control unit 40A transmits an operation signal to the first power unit 11 to close the opening / closing door 10 (S21). Based on the operation signal received from the power control unit 40A, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door closing operation (S22).

[0053] Figure 4 is a sequence diagram showing the processes performed by each device when the opening / closing door 10 transitions from the open state to the closed state. When the closing limit detection sensor 13 detects that the opening / closing door 10 is fully closed, it outputs a detection ON signal to the operation control unit 60. When the operation control unit 60 receives the detection ON signal from the closing limit detection sensor 13 (YES in S23), it outputs an operation stop command to the power control unit 40A (S24). When the power control unit 40A receives the operation stop command from the operation control unit 60, it transmits a stop signal to the first power unit 11 (S25).

[0054] Based on the stop signal received from the power control unit 40A, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S26).

[0055] When the operation control unit 60 receives the detection ON signal from the closing limit detection sensor 13, it further notifies the safety controller 80A that the closing operation has ended because the opening / closing door 10 has been fully closed (S27).

[0056] Based on the notification received from the operation control unit 60, the safety controller 80A terminates monitoring of the open / closed status of the second switch 921, the third switch 922, the fourth switch 931, and the fifth switch 932 (S28). Once the safety controller 80A has terminated monitoring of the open / closed status of these switches, it sends an equipment operation permission notification to the operation control unit 60, which authorizes the operation of each piece of equipment (S29).

[0057] When the operation control unit 60 receives a notification of permission to operate equipment from the safety controller 80A, it accepts this notification and transitions to a state in which it can operate the equipment based on the operation commands of each piece of equipment that are issued thereafter (S30). This makes it possible to store a vehicle into the mechanical parking garage P using the swivel device 20 and the lift device 30. This concludes the explanation of the processes performed by each piece of equipment when the opening and closing door 10 in the mechanical parking garage P is opened and closed according to the first embodiment.

[0058] According to the first embodiment described above, the equipment management system includes a power control unit that drives the operating mechanism of equipment including opening and closing doors within the facility, an operation control unit that controls the power control unit, and a safety controller. The safety controller restricts the operation of at least one of the equipment other than the opening and closing doors by the power control unit while the opening and closing doors are being opened and closed by the operation control unit, and restricts the operation of at least one of all of the equipment including the opening and closing doors by the power control unit while the fully open state of the opening and closing doors is maintained.

[0059] Specifically, the equipment management system is equipped with a switch that switches between connected and disconnected states, installed on each power supply line connecting the power control unit and each piece of equipment. The safety controller monitors the connected / disconnected state of the switches installed on the power supply lines connecting the power control unit and equipment other than the doors, from the start of the opening operation of the opening / closing doors controlled by the operation control unit until the doors are fully closed. If the controller detects that the doors have become connected during monitoring, it executes an emergency stop function that stops the operation of the entire system.

[0060] This makes it possible to ensure the safety of users during the opening and closing of doors in facilities equipped with electric equipment, including doors.

[0061] [Modified form of the first embodiment (1)] In the first embodiment described above, when the safety controller 80A is notified by the operation control unit 60 in step S11 that the opening operation of the opening / closing door 10 has been stopped, it may temporarily terminate the monitoring of the open / closed state of the second switch 921, third switch 922, fourth switch 931, and fifth switch 932, which was started in step S6, and then resume monitoring of the open / closed state of these switches when it receives a restriction release command from the operation control unit 60 in step S15.

[0062] While the opening / closing door 10 is stopped in the fully open position, the STO function restricts the operation of each piece of equipment by command from the safety controller 80A. Therefore, as mentioned above, there is no safety issue even without monitoring the open / closed state of the switch.

[0063] When the system operates in this manner, the safety controller 80A does not send an equipment operation permission notification to the operation control unit 60 when it sends the restriction release command in step S18 because it is not monitoring the open / closed state of the switch. After a predetermined time has elapsed since the transmission of the restriction release command in step S15, the operation control unit 60 sends a door close command to the power control unit 40A without receiving the equipment operation permission notification.

[0064] This reduces the load on the safety controller, allowing for more efficient operation of the equipment management system.

[0065] [Modified form of the first embodiment (2)] Furthermore, in the first embodiment described above, the safety controller 80A may not recognize in step S28 that the opening / closing door 10 has been fully closed by notification from the operation control unit 60, but rather based on the detection result of a second closing limit detection sensor (not shown), which is a safety sensor that detects when the opening / closing door 10 has switched from an open state to a closed state, or on the detection result of a door closing detection sensor (not shown), which is a safety sensor that detects the closed state by turning ON when the opening / closing door 10 is closed and OFF when it is open.

[0066] This allows the safety controller to recognize when the door is fully closed based on various sensors installed in the equipment management system, and to release the operation restrictions as appropriate.

[0067] [Modified form of the first embodiment (3)] In the first embodiment described above, the power unit of the equipment that cannot operate simultaneously with the opening / closing door 10 and the power supply may be directly connected by a power supply line without going through the power control unit 40A, and an eighth switch (not shown) may be set on this power supply line to configure the equipment management system 1A. In this case, when the opening / closing door 10 is in the open state, the safety controller 80A monitors the open / closed state of the eighth switch, and when it detects that the eighth switch has closed during monitoring, it executes an emergency stop function to stop the operating mechanism of the equipment that cannot operate simultaneously with the opening / closing door 10.

[0068] This allows monitoring of equipment that cannot operate simultaneously with the opening and closing door 10 during the opening and closing operation of the door 10 to be performed with a simple configuration.

[0069] 《Second Embodiment》 <Configuration of the equipment management system according to the second embodiment> Figure 5 is an overall diagram showing the configuration of the equipment management system 1B according to the second embodiment of the present invention. The equipment management system 1B comprises a first piece of equipment, an opening / closing door 10, a second piece of equipment, a swivel device 20, and a third piece of equipment, a lift device 30, all installed in a mechanical parking garage P, as well as a power control unit 40B, an operation reception unit 50, an operation control unit 60, an emergency notification unit 70, and a safety controller 80B. Of these, detailed explanations of components that have the same functions as the equipment management system 1A described in the first embodiment are omitted.

[0070] The power control unit 40B includes a door power control unit 41 and an equipment power control unit 42. The door power control unit 41 operates or stops the first power unit 11 of the opening / closing door 10 based on signals transmitted from the operation control unit 60 and the safety controller 80B. The door power control unit 41 and the first power unit 11 are connected by a power supply line 94 and a communication line 104.

[0071] The equipment power control unit 42 operates or stops the second power unit 21 of the slewing device 20 and the third power unit 31 of the lifting device 30 based on signals transmitted from the operation control unit 60 and the safety controller 80B.

[0072] The equipment power control unit 42 and the second power unit 21 of the slewing device 20 are connected by a power supply line 95 and a communication line 105. A sixth switch 951 is installed on the power supply line 95 to switch the connection between the equipment power control unit 42 and the second power unit 21 ON / OFF.

[0073] Furthermore, the equipment power control unit 42 and the third power unit 31 of the lift device 30 are connected by a power supply line 96 and a communication line 106, and a seventh switch 961 is installed on the power supply line 96 to switch the connection between the equipment power control unit 42 and the third power unit 31 ON / OFF.

[0074] The operation control unit 60 controls the door power control unit 41 and the equipment power control unit 42 based on the operation information received by the operation reception unit 50. Furthermore, when the operation control unit 60 detects an abnormality that has occurred in the safety controller 80B, it outputs a stop signal to the door power control unit 41 and the equipment power control unit 42 to stop the operation of the equipment.

[0075] When the safety controller 80B detects an abnormality occurring in the open limit detection sensor 12, the closed limit detection sensor 13, the operation control unit 60, or the safety controller 80B itself, when it detects an abnormality occurring within the equipment or within the sensors based on sensor signals acquired from these sensors, or when it receives an emergency notification output from the emergency notification unit 70, it outputs a stop signal to the door power control unit 41 and the equipment power control unit 42 to stop the operation of the equipment. In addition, when the safety controller 80B detects any of these abnormalities, it outputs a signal to the operation control unit 60 to inform it of the abnormality.

[0076] Furthermore, the safety controller 80B restricts the operation of the slewing device 20 and the lifting device 30, which are other equipment controlled by the equipment power control unit 42, from the start of the opening operation of the door 10 controlled by the operation control unit 60 until it is fully closed. In addition, the safety controller 80B further restricts the operation of the door 10 controlled by the door power control unit 41 from the time the door 10 is fully open until the closing operation of the door 10 controlled by the operation control unit 60 begins.

[0077] <Operation of the equipment management system according to the second embodiment> This section describes the processes performed by each device in the equipment management system 1B when the opening and closing door 10 in the mechanical parking garage P opens and closes. Figure 6 is a sequence diagram showing the processes performed by each device from the time the opening and closing door 10 transitions from the closed state to the open state until it is fully open.

[0078] In the initial state, the opening / closing door 10 is closed, and the first power unit 11 is stopped. Also, the sixth switch 951 and the seventh switch 961 are open.

[0079] When a user performs a door opening operation at the operation reception unit 50 to open the door 10, the operation reception unit 50 transmits a door opening command to the operation control unit 60.

[0080] When the operation control unit 60 receives a door open command from the operation reception unit 50 (YES in S31), it notifies the safety controller 80B that the opening of the door 10 has begun (S32).

[0081] Based on the notification received from the operation control unit 60, the safety controller 80B transmits an operation restriction command to the equipment power control unit 42 (S33). Upon receiving the operation restriction command from the safety controller 80B, the equipment power control unit 42 restricts the operation of the first power unit 11, the second power unit 21, and the third power unit 31 by limiting the power supply to these devices (S34).

[0082] Furthermore, when the safety controller 80B transmits an operation restriction command, it transmits a door operation permission notification to the operation control unit 60 that permits the operation of the open / closed door 10 which is not restricted (S35). When the operation control unit 60 receives the door operation permission notification from the safety controller 80B, it accepts this permission notification (S36) and transmits the door open command received in step S31 to the door power control unit 41 (S37).

[0083] The door power control unit 41 transmits an operation signal to the first power unit 11 to open the opening door 10 based on the door closing command from the operation control unit 60 (S38). Based on the operation signal received from the door power control unit 41, the first power unit 11 of the opening door 10 switches from "stopped" to "operating" and starts the door opening operation (S39).

[0084] When the opening limit detection sensor 12 detects that the opening / closing door 10 is fully open, it outputs a detection ON signal to the operation control unit 60. When the operation control unit 60 receives the detection ON signal from the opening limit detection sensor 12 (YES in S40), it sends an operation stop command to the door power control unit 41 (S41).

[0085] When the door power control unit 41 receives a stop command from the operation control unit 60, it transmits a stop signal to the first power unit 11 (S42). Based on the stop signal received from the door power control unit 41, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S43).

[0086] Furthermore, when the operation control unit 60 receives a detection ON signal from the opening limit detection sensor 12, it notifies the safety controller 80B that the opening operation has ended because the opening door 10 has been fully opened (S44).

[0087] Based on the notification received from the operation control unit 60, the safety controller 80B transmits an operation restriction command to the door power control unit 41 (S45). When the door power control unit 41 receives the operation restriction command from the safety controller 80B, it restricts the operation by cutting off the power supply to the opening and closing door 10 (S46).

[0088] Figure 7 is a sequence diagram showing the processes performed by each device when the door closing operation is performed after the door opening 10 has been fully opened.

[0089] After the door 10 is fully open, the user performs a door closing operation at the operation reception unit 50 to close the door 10, and the operation reception unit 50 sends a door closing command to the operation control unit 60, or a determination unit (not shown) that automatically determines the timing of the closing operation of the door 10 sends a door closing command to the operation control unit 60, at which point the operation control unit 60 receives this door closing command (YES in S47).

[0090] When the operation control unit 60 receives a door closing command, it notifies the safety controller 80B that the door closing operation of the opening / closing door 10 has begun (S48). Based on the notification received from the operation control unit 60, the safety controller 80B sends a restriction release command to the door power control unit 41 (S49). When the door power control unit 41 receives the restriction release command from the safety controller 80B, it releases the operation restriction on the opening / closing door 10 that was imposed in step S46 (S50).

[0091] Furthermore, when the safety controller 80B transmits a command to release the restriction, it transmits a door operation permission notification to the operation control unit 60 that permits the operation of the opening and closing door 10 (S51). When the operation control unit 60 receives the door operation permission notification from the safety controller 80B, it accepts this permission notification (S52) and transmits the door closing command received in step S47 to the door power control unit 41 (S53).

[0092] The door power control unit 41 transmits an operation signal to the first power unit 11 to close the opening / closing door 10 based on the door closing command from the operation control unit 60 (S54). Based on the operation signal received from the door power control unit 41, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door closing operation (S55).

[0093] Figure 8 is a sequence diagram showing the processes performed by each device when the opening / closing door 10 transitions from the open state to the closed state. When the closing limit detection sensor 13 detects that the opening / closing door 10 is fully closed, it outputs a detection ON signal to the operation control unit 60. When the operation control unit 60 receives the detection ON signal from the closing limit detection sensor 13 (YES in S56), it outputs an operation stop command to the door power control unit 41 (S57). When the door power control unit 41 receives the operation stop command from the operation control unit 60, it transmits a stop signal to the first power unit 11 (S58).

[0094] Based on the stop signal received from the door power control unit 41, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S59).

[0095] Furthermore, when the operation control unit 60 receives a detection ON signal from the closing limit detection sensor 13, it notifies the safety controller 80A that the door closing operation has stopped because the opening / closing door 10 has been fully closed (S60). Based on the notification received from the operation control unit 60, the safety controller 80B sends an operation restriction command to the door power control unit 41 (S61). When the door power control unit 41 receives the operation restriction command from the safety controller 80B, it imposes an operation restriction on the opening / closing door 10 (S62).

[0096] The safety controller 80B also transmits a command to release the restriction to the equipment power control unit 42 (S63). When the equipment power control unit 42 receives the command to release the restriction from the safety controller 80B, it releases the operational restrictions on the slewing device 20 and the lifting device 30 that were imposed in step S34 (S64).

[0097] Furthermore, when the safety controller 80B transmits a command to release the restriction, it transmits an equipment operation permission notification to the operation control unit 60 that permits the operation of the slewing device 20 and the lifting device 30 (S65). When the operation control unit 60 receives the door operation permission notification from the safety controller 80B, it accepts this permission notification and transitions to the equipment operation enabled state (S66). Once the operation control unit 60 has transitioned to the equipment operation enabled state, when it subsequently receives an operation command related to the slewing device 20 or the lifting device 30, it transmits this operation command to the equipment power control unit 42 to execute the operation of the equipment to be operated by the power unit.

[0098] According to the second embodiment described above, the power control unit includes a door power control unit that drives the operating mechanism of the opening and closing door, and an equipment power control unit that drives the operating mechanism of equipment other than the opening and closing door. The safety controller restricts the operation of equipment other than the opening and closing door by the equipment power control unit from the start of the opening operation of the opening and closing door controlled by the operation control unit until it is fully closed, and further restricts the operation of the opening and closing door by the door power control unit from the time the opening and closing door is fully open until the closing operation of the opening and closing door controlled by the operation control unit begins.

[0099] This makes it possible to ensure the safety of users during the opening and closing of doors in facilities equipped with electric equipment, including doors.

[0100] In the second embodiment, multiple equipment power control units may be provided for each piece of equipment or for each group of equipment. This allows for efficient control of the operation restrictions / releases of each piece of equipment.

[0101] Furthermore, in the first and second embodiments described above, the power unit of each device may feed back signals indicating its operating status to the power control units 40A and 40B via a communication line. This allows the power control units 40A and 40B to output operation instructions while checking the operating status of each power unit.

[0102] While embodiments of the present invention have been described above, it is possible to modify or transform the embodiments based on the above disclosure. All components of the above embodiments, and all features described in the claims, may be individually selected and combined, provided that they do not contradict each other.
