Summary of the Invention

Problems to be Solved by the Invention

[0004] 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.

[0005] In order to cope with this, by installing a door closed detection sensor for detecting the closed state of the opening and closing door, when this sensor enters a state where it does not detect the closing of the door (detection OFF state), the operation control unit can recognize that the opening and closing door is in the open state and stop the operation of the facilities in the parking lot.

[0006] However, as mentioned above, if the operation of the equipment is managed based on the detection status of the door closure detection sensor, there is a problem in that even when a user intentionally opens or closes the door to enter or exit the parking lot, the door closure detection sensor will turn OFF, stopping the operation of the equipment in the mechanical parking lot, and the operation of the door itself will stop, causing inconvenience to the user.

[0007] This invention has been made in view of the above circumstances, and aims to provide an equipment management system and equipment management method that can ensure the safety of users while reliably performing the operation of the equipment as intended by the user when they use a facility equipped with electric equipment, including opening and closing doors. [Means for solving the problem]

[0008] To achieve the above objective, the present invention provides a facility management system comprising: a door closing detection sensor for detecting the closed state of an opening / closing door within a facility; a power control unit for driving the operating mechanism of the facility including the opening / closing door within the facility; an operation control unit for controlling the power control unit; and a safety controller. The safety controller, when the door closing detection sensor does not detect the closed state of the opening / closing door, determines whether the opening / closing door is in operation through the control of the operation control unit. If the operation control unit determines that the opening / closing door is not in operation, it enables a stop signal output function that outputs a stop signal to the power control unit to stop at least one of the facilities. If the operation control unit determines that the opening / closing door is in operation, it disables the stop signal output function.

[0009] Furthermore, the equipment management method of the present invention includes a door closing detection sensor that detects the closed state of an opening / closing door within a facility, a power control unit that drives the operating mechanism of equipment including the opening / closing door within the facility, and an operation control unit that controls the power control unit. A safety controller, which is communicably connected to these three units, determines whether the opening / closing door is in operation or not when the door closing detection sensor does not detect the closed state of the opening / closing door. If the operation control unit determines that the opening / closing door is not in operation, it enables a stop signal output function that outputs a stop signal to the power control unit to stop at least one of the equipment. If the operation control unit determines that the opening / closing door is in operation, it disables the stop signal output function. [Effects of the Invention]

[0010] According to the equipment management system and equipment management method of the present invention, when a user uses a facility equipped with electric equipment including opening and closing doors, it is possible to ensure the safety of the user while reliably performing the operation of the equipment as intended by the user.

[Figure 9] This is a sequence diagram showing the processes performed by each device when an opening / closing door transitions from an open state to a closed state in the equipment management system according to the fifth embodiment. [Modes for carrying out the invention]

[0012] Below, as an embodiment of the present invention, a facility management system for managing a mechanical parking garage P, which is a facility having multiple electrically operated devices including opening and closing doors, will be described with reference to the drawings. The mechanical parking garage P is equipped with multiple electrically operated devices, such as opening and closing doors and lift devices for transporting stored items to different floors.

[0013] 《First Embodiment》 <Configuration of the equipment management system according to the first embodiment> Figure 1 is an overall diagram showing the configuration of the 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.

[0014] The equipment management system 1A comprises a first piece of equipment, an opening / closing door 10, and a second piece of equipment, a lift device 20, installed in the mechanical parking garage P, as well as a power control unit 30, an operation reception unit 40, an operation control unit 50, an emergency notification unit 60, and a safety controller 70A. The equipment within the mechanical parking garage P is not limited to an opening / closing door and a lift device; any electrically powered device is acceptable. Furthermore, the number of pieces of equipment is not limited to two; there may be one or three or more.

[0015] The opening / closing door 10 is a door installed at the entrance / exit of the mechanical parking lot P, and has a first power unit 11, a door closed detection sensor 12, an open limit detection sensor 13, and a first closed limit detection sensor 14. The first power unit 11 is a mechanism for opening and closing the opening / closing door 10. The door closed detection sensor 12 is a safety sensor for detecting the closed state of the opening / closing door 10. The door closed detection sensor 12 is, for example, a sensor that physically detects the closed state of the opening / closing door 10, a sensor that detects non-contact electromagnetically, a sensor that detects by analyzing imaging information obtained by photographing the opening / closing door 10, a sensor that detects by measuring the moving distance of the opening / closing door 10 due to the opening / closing operation, a sensor that detects by measuring the position of the opening / closing door 10, etc.

[0016] The door closed detection sensor 12 outputs a state signal indicating that it is in a detection ON state at a predetermined time interval while the opening / closing door 10 is in the closed state to the safety controller 70A. The door closed detection sensor 12 is equipped with a self-check function for detecting abnormalities in itself.

[0017] The open limit detection sensor 13 is an operation sensor for detecting that the opening / closing door 10 is fully open when the opening / closing door 10 reaches a predetermined door stop position due to full opening. The first closed limit detection sensor 14 is an operation sensor for detecting that the opening / closing door 10 is fully closed when the opening / closing door 10 reaches a predetermined door stop position due to full closing. The open limit detection sensor 13 and the first closed limit detection sensor 14 are, for example, sensors that physically detect that the opening / closing door 10 has reached the door stop position, sensors that detect non-contact electromagnetically, sensors that detect by analyzing imaging information obtained by photographing the opening / closing door 10, sensors that detect by measuring the moving distance of the opening / closing door 10 due to the opening / closing operation, sensors that detect by measuring the position of the opening / closing door 10, etc. The open limit detection sensor 13 and the first closed limit detection sensor 14 output detection information to the operation control unit 50.

[0018] The lift device 20 has a second power unit 21 and a second safety sensor 22. The second power unit 21 is a mechanism for raising and lowering a vehicle within the mechanical parking lot P. The second safety sensor 22 is a device that performs measurements for monitoring the safety of the operation of the lift device 20, and is composed of, for example, a limit position detection sensor that detects the maximum position within the operating range of the lift device 20.

[0019] The power control unit 30 is composed of, for example, an inverter, a switch, a PLC (programmable logic controller), etc., and operates and stops the first power unit 11 of the opening / closing door 10 and the second power unit 21 of the lift device 20 based on signals transmitted from the operation control unit 50 and the safety controller 70A as described later. The power control unit 30 may be installed in a redundant manner for one power unit to enhance fault tolerance.

[0020] The power control unit 30 stops the first power unit 11 and the second power unit 21 by any one of, for example, 1) operation stop switching control by software, 2) operation stop switching control performed after adjusting the operation speed by software, and 3) power supply cutoff control using a switch. The power control unit 30 may be set to adopt any one of the above 1) to 3) separately when controlling the operation of the equipment based on a signal from the operation control unit 50 and when controlling the operation of the equipment based on a signal from the safety controller 70A. Alternatively, the power control unit 30 may be set to adopt any one of the above 1) to 3) for each piece of equipment whose operation is to be controlled.

[0021] When the power control unit 30 stops the operations of the opening / closing door 10 and the lift device 20, it may be in a stop state where the mechanical parking lot P itself cannot be used, or it may be in a stop state where the mechanical parking lot P can be restored by a signal from the outside.

[0022] The operation reception unit 40 is composed of, for example, an operation panel installed in the mechanical parking lot P or at a remote location, a remote controller or a smart device held by the user, etc., and receives information on operations related to the use of the mechanical parking lot P by the user. The operation reception unit 40 may also be composed of a terminal communicably connected to a remote management device that remotely manages the mechanical parking lot P, and receive information on operations for operating the equipment in the mechanical parking lot P output from this remote management device.

[0023] The motion control unit 50 is composed of, for example, a PLC or a personal computer (PC), and controls the power control unit 30 based on the operation information received by the operation reception unit 40. Furthermore, when the motion control unit 50 detects an abnormality that has occurred in the safety controller 70A, it outputs a stop signal to the power control unit 30 to stop the operation of the motion control unit.

[0024] The emergency notification unit 60 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 70A. The emergency notification unit 60 may be installed near equipment such as the opening / closing door 10 or the lift device 20, or it may be integrated with the operation reception unit 40 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 60 and the safety controller 70A.

[0025] The safety controller 70A 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 70A detects an abnormality occurring in the door closing detection sensor 12, the opening limit detection sensor 13, the first closing limit detection sensor 14, the operation control unit 50, or the safety controller 70A itself, when it detects an abnormality occurring in the equipment or within the sensor based on the sensor signals acquired from these sensors, or when it acquires an emergency notification output from the emergency notification unit 60, it transmits a stop signal to the power control unit 30.

[0026] Specifically, when the door closing detection sensor 12 transitions from the detection ON state to the detection OFF state, the safety controller 70A determines, under the control of the operation control unit 50, whether or not the opening / closing door 10 is in operation. If the safety controller 70A determines, under the control of the operation control unit 50, that the opening / closing door 10 is not in operation, it has a stop signal output function that outputs a stop command to the power control unit 30 to stop the operating mechanism of at least one piece of equipment in the mechanical parking system P, including the opening / closing door 10. Furthermore, if the safety controller 70A determines, under the control of the operation control unit 50, that the opening / closing door 10 is in operation, it disables the stop signal output function.

[0027] <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 a closed state to an open state. In the initial state, the opening and closing door 10 is in the closed state, so the first power unit 11 is stopped, and the door closing detection sensor 12 is in the detection ON state.

[0028] When a user performs a door opening operation at the operation reception unit 40 to open the door 10, the operation reception unit 40 transmits a door opening command to the operation control unit 50.

[0029] When the operation control unit 50 receives a door open command from the operation reception unit 40 (YES in S1), it transmits operation information to the safety controller 70A indicating that the opening / closing door 10 should be opened (S2). The safety controller 70A holds the operation information obtained from the operation control unit 50 (S3).

[0030] The operation control unit 50 also transmits a door open command for the opening / closing door 10 to the power control unit 30 (S4). Based on the door open command from the operation control unit 50, the power control unit 30 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 30, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door opening operation (S6).

[0031] When the door opening operation of the door opening / closing door 10 begins, the detection state of the door closing detection sensor 12 transitions to the detection OFF state (S7), and the safety controller 70A recognizes this (S8). When the safety controller 70A recognizes that the detection state of the door closing detection sensor 12 has transitioned to the detection OFF state, it determines whether or not the door opening / closing door 10 is in operation under the control of the operation control unit 50 (S9).

[0032] Here, in step S3, the safety controller 70A holds operation information transmitted from the operation control unit 50 indicating that the opening / closing door 10 should be in the open state, and therefore determines that the opening / closing door 10 is in operation (YES in S9). When the safety controller 70A determines that the opening / closing door 10 is in operation, it disables the stop signal output function (S10). When the safety controller 70A disables the stop signal output function, it does not determine that an abnormality has occurred even if the door closing detection sensor 12 is in the OFF state, and does not output an operation stop command to stop the operating mechanism of the equipment in the mechanical parking lot P.

[0033] In step S9, if the safety controller 70A determines that the door 10 is not operating and does not hold any operational information for the door 10 (NO in S9), it determines that an abnormality has occurred because the door closing detection sensor 12 is in the OFF state despite the door 10 not operating, and outputs a stop command to the power control unit 30 to stop the operating mechanism of the equipment in the mechanical parking lot P (S11). When the power control unit 30 receives the stop command from the operation control unit 50, it sends a stop signal to the operating mechanism of each piece of equipment, including the first power unit 11 and the second power unit 21, to stop their operation (S12).

[0034] Figure 3 is a sequence diagram showing the processes performed by each device after the safety controller 70A disables the stop signal output function in step S10. When the opening limit detection sensor 13 detects that the opening / closing door 10 is fully open, it outputs a detection ON signal to the operation control unit 50. When the operation control unit 50 receives the detection ON signal from the opening limit detection sensor 13 (YES in S21), it outputs an operation stop command to the power control unit 30 (S22).

[0035] When the power control unit 30 receives a stop command from the operation control unit 50, it transmits a stop signal to the first power unit 11 (S23). Based on the stop signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S24).

[0036] Subsequently, when the user performs a door closing operation at the operation reception unit 40 to close the opening / closing door 10, the operation reception unit 40 sends a door closing command to the operation control unit 50, or when a determination unit (not shown) that automatically determines the timing of the closing operation of the opening / closing door 10 sends a door closing command to the operation control unit 50, the operation control unit 50 receives this door closing command (YES in S25).

[0037] When the operation control unit 50 receives a door closing command, it transmits a door closing command for the opening / closing door 10 to the power control unit 30 (S26). Based on the door closing command from the operation control unit 50, the power control unit 30 transmits an operation signal to the first power unit 11 to close the opening / closing door 10 (S27). Based on the operation signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door closing operation (S28).

[0038] 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 first closing limit detection sensor 14 detects that the opening / closing door 10 is fully closed, it outputs a detection ON signal to the operation control unit 50. When the operation control unit 50 receives the detection ON signal from the first closing limit detection sensor 14 (YES in S31), it transmits operation information to the safety controller 70A indicating that the opening / closing door 10 has entered the closed state (S32).

[0039] The safety controller 70A recognizes that the door 10 is fully closed based on the operation information obtained from the operation control unit 50 (S33). When the safety controller 70A recognizes that the door 10 is fully closed, it sets the stop signal output function to be enabled (S34). When the safety controller 70A sets the information of the door closure detection sensor 12 to be enabled, it determines that an abnormality has occurred when the door closure detection sensor 12 subsequently turns OFF, and outputs an operation stop command to stop the operating mechanism of the equipment in the mechanical parking lot P.

[0040] When the motion control unit 50 acquires the detection ON signal from the first closing limit detection sensor 14, it further outputs a stop command to the power control unit 30 (S35). When the power control unit 30 receives the stop command from the motion control unit 50, it transmits a stop signal to the first power unit 11 (S36).

[0041] Based on the stop signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S37). When the opening / closing door 10 is in the closed state, the detection state of the door closing detection sensor 12 transitions to the detection ON state (S38). This concludes the explanation of the processes performed by each device when the opening / closing door 10 in the mechanical parking lot P is opened and closed according to the first embodiment.

[0042] According to the first embodiment described above, the equipment management system includes a door closing detection sensor that detects the closed state of an opening / closing door within the facility, a power control unit that drives the operating mechanism of the equipment including the opening / closing door within the facility, an operation control unit that controls the power control unit, and a safety controller. When the door closing detection sensor enters a detection OFF state where it does not detect the closed state of the opening / closing door, the safety controller has the operation control unit determine whether or not the opening / closing door is in operation. If the operation control unit determines that the opening / closing door is not in operation, it outputs a stop signal to the power control unit to stop the operating mechanism of the equipment including the opening / closing door. If the operation control unit determines that the opening / closing door is in operation, it invalidates the detection information from the door closing detection sensor and does not output a stop signal.

[0043] This ensures that when a user uses a facility equipped with electric equipment, including doors, the operating mechanism of the equipment within the facility stops if the door is unintentionally opened, thereby ensuring the user's safety. It also ensures that when the door is intentionally opened, it is reliably opened. This "intentional operation to open the door" may be performed by the user, or by an autonomous mobile device such as an autonomous vehicle or delivery robot, or by an operator remotely controlling the mobile device.

[0044] Furthermore, in this embodiment, the safety controller switches the detection information of the door closing detection sensor between disabled and enabled without stopping the operation of the door closing detection sensor. This ensures that the door opening operation intended by the user is performed, maintaining the power ON state of the door closing detection sensor and enabling its self-check function. This allows for rapid notification of any abnormal condition that occurs in the door closing detection sensor.

[0045] Furthermore, the equipment management system according to this embodiment further includes a first closing limit detection sensor that detects when the opening / closing door is fully closed based on control information from the operation control unit. The safety controller disables the detection information from the door closing detection sensor, and then, when the first closing limit detection sensor detects that the opening / closing door is fully closed, it enables the detection information from the door closing detection sensor.

[0046] This ensures that when a door is returned to the closed position by user operation, the detection information from the door closing detection sensor becomes effective, thereby ensuring safety from that point onward.

[0047] 《Second Embodiment》 <Configuration of the equipment management system according to the second embodiment> Since the configuration of the equipment management system 1B according to the second embodiment is the same as that of the equipment management system 1A described in the first embodiment, a detailed explanation of the parts having the same function will be omitted.

[0048] In this embodiment, the safety controller 70B disables the stop signal output function, and then, when the opening limit detection sensor 13 detects that the opening / closing door 10 is fully open, it enables the stop signal output function. Subsequently, when the safety controller 70B detects that the closing operation of the opening / closing door 10 by the first power unit 11 has started under the control of the power control unit 30, it disables the stop signal output function. Furthermore, when the safety controller 70B detects that the opening / closing door 10 is fully closed, it enables the stop signal output function.

[0049] <Operation of the equipment management system according to the second embodiment> 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 will now be described. In this embodiment, the processes performed by each device when the opening and closing door 10 transitions from the closed state to the open state are the same as the processes in steps S1 to S12 described in the first embodiment, so a detailed explanation will be omitted.

[0050] Figure 5 is a sequence diagram showing the processes performed by each device after the safety controller 70B disables the stop signal output function in step S10. When the opening limit detection sensor 13 detects that the opening / closing door 10 is fully open, it outputs a detection ON signal to the operation control unit 50. When the operation control unit 50 receives the detection ON signal from the opening limit detection sensor 13 (YES in S41), it transmits operation information indicating that the opening / closing door 10 is fully open to the safety controller 70B (S42).

[0051] The safety controller 70B recognizes that the door 10 is fully open based on the operation information obtained from the operation control unit 50 (S43). When the safety controller 70B recognizes that the door 10 is fully open, it enables the stop signal output function (S44).

[0052] When the motion control unit 50 acquires the detection ON signal from the opening limit detection sensor 13, it further outputs a stop command to the power control unit 30 (S45). When the power control unit 30 receives the stop command from the motion control unit 50, it transmits a stop signal to the first power unit 11 (S46).

[0053] Based on the stop signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S47).

[0054] Subsequently, when the user performs a door closing operation at the operation reception unit 40 to close the opening / closing door 10, the operation reception unit 40 sends a door closing command to the operation control unit 50, or when a determination unit (not shown) that automatically determines the timing of the closing operation of the opening / closing door 10 sends a door closing command to the operation control unit 50, the operation control unit 50 receives this door closing command (YES in S48).

[0055] When the operation control unit 50 receives a door closing command, it transmits operation information to the safety controller 70B indicating that the opening / closing door 10 should be closed (S49). Based on the operation information obtained from the operation control unit 50, the safety controller 70B recognizes the start of the door closing operation of the opening / closing door 10 (S50). When the safety controller 70B recognizes the start of the door closing operation of the opening / closing door 10, it disables the stop signal output function (S51).

[0056] When the operation control unit 50 receives a door closing command, it further transmits a door closing command for the opening / closing door 10 to the power control unit 30 (S52). Based on the door closing command from the operation control unit 50, the power control unit 30 transmits an operation signal to the first power unit 11 to close the opening / closing door 10 (S53). Based on the operation signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door closing operation (S54).

[0057] From this point onward, the processes performed by each device when the opening / closing door 10 transitions from the open state to the closed state are the same as those described in steps S31 to S38 of the first embodiment, so a detailed explanation will be omitted. This concludes the explanation of the processes performed by each device when the opening / closing door 10 in the mechanical parking garage P opens and closes according to the second embodiment.

[0058] The equipment management system according to the second embodiment described above further includes, in addition to the equipment management system described in the first embodiment, an open limit detection sensor that detects when the door is fully open based on control information from the operation control unit, and a first closed limit detection sensor that detects when the door is fully closed based on control information from the operation control unit. Furthermore, the safety controller disables the detection information from the door closed detection sensor, and then, when the open limit detection sensor detects that the door is fully open, it enables the detection information from the door closed detection sensor. Subsequently, when the operation control unit detects that the closing operation of the door has started, it disables the detection information from the door closed detection sensor. Subsequently, when the first closed limit detection sensor detects that the door is fully closed, it enables the detection information from the door closed detection sensor.

[0059] This ensures that when users use facilities equipped with electric equipment, including doors, even if the doors are in the open position due to user operation, the system can activate detection information from the door closing detection sensor and stop the operation of the equipment within the facility while the doors are fully open and stopped, thereby more reliably ensuring the safety of users.

[0060] 《Third Embodiment》 <Configuration of the equipment management system according to the third embodiment> Since the configuration of the equipment management system 1C according to the third embodiment is the same as that of the equipment management system 1A described in the first embodiment, a detailed explanation of the parts having the same function will be omitted.

[0061] In this embodiment, after disabling the stop signal output function, the safety controller 70C enables the stop signal output function when it recognizes that the detection state of the door closing detection sensor 12 has transitioned from the detection OFF state to the detection ON state.

[0062] <Operation of the equipment management system according to the third embodiment> This section describes the processes performed by each device in the equipment management system 1C when the opening and closing door 10 in the mechanical parking garage P opens and closes. In this embodiment, the processes performed by each device when the opening and closing door 10 transitions from the closed state to the open state are the same as the processes in steps S1 to S28 described in the first embodiment, so a detailed explanation is omitted.

[0063] Figure 6 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 first closing limit detection sensor 14 detects that the opening / closing door 10 is fully closed, it outputs a detection ON signal to the operation control unit 50. When the operation control unit 50 receives the detection ON signal from the first closing limit detection sensor 14 (YES in S61), it outputs an operation stop command to the power control unit 30 (S62). When the power control unit 30 receives the operation stop command from the operation control unit 50, it transmits a stop signal to the first power unit 11 (S63).

[0064] Based on the stop signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S64). When the opening / closing door 10 is in the closed state, the detection state of the door closing detection sensor 12 transitions from the detection OFF state to the detection ON state (S65).

[0065] When the detection state of the door closing detection sensor 12 transitions to the detection ON state, the safety controller 70C detects this and activates the stop signal output function (S66). This concludes the explanation of the processes performed by each device when the opening and closing door 10 in the mechanical parking lot P is opened and closed according to the third embodiment.

[0066] According to the third embodiment described above, after disabling the detection information from the door closing detection sensor, the safety controller enables the detection information from the door closing detection sensor when it detects that the detection state of the door closing detection sensor has transitioned from the detection OFF state to the detection ON state.

[0067] This allows the facility management system to reliably switch to a state that ensures user safety by disabling the detection information from the door closing detection sensor when a user opens or closes the door, and then re-enabling the detection information from the door closing detection sensor when the door returns to the closed state due to the closing operation.

[0068] 《Fourth Embodiment》 <Configuration of the equipment management system according to the fourth embodiment> Figure 7 is an overall diagram showing the configuration of the equipment management system 1D according to the fourth embodiment. The configuration of the equipment management system 1D is the same as that of the equipment management system 1A described in the first embodiment, except that the opening / closing door 10 is equipped with a second closing limit detection sensor 15, so a detailed explanation of the parts that have the same function will be omitted.

[0069] The second closing limit detection sensor 15 is a safety sensor that detects the switching of the opening / closing door 10 from the open state to the closed state. When the second closing limit detection sensor 15 detects the switching of the opening / closing door 10 from the open state to the closed state, it outputs a detection ON signal to the safety controller 70D.

[0070] In this embodiment, the safety controller 70D disables the stop signal output function, and then, when the second closing limit detection sensor 15 detects that the opening / closing door 10 has switched from the closed state to the closed state, it enables the stop signal output function.

[0071] <Operation of the equipment management system according to the fourth embodiment> This section describes the processes performed by each device in the equipment management system 1D when the opening and closing door 10 in the mechanical parking garage P opens and closes. In this embodiment, the processes performed by each device when the opening and closing door 10 transitions from the closed state to the open state are the same as the processes in steps S1 to S28 described in the first embodiment, so a detailed explanation is omitted.

[0072] 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 first closing limit detection sensor 14 detects that the opening / closing door 10 is fully closed, it outputs a detection ON signal to the operation control unit 50. When the operation control unit 50 receives the detection ON signal from the first closing limit detection sensor 14 (YES in S71), it sends an operation stop command to the power control unit 30 (S72). When the power control unit 30 receives the operation stop command from the operation control unit 50, it sends a stop signal to the first power unit 11 to stop its operation (S73).

[0073] Based on the stop signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S74). When the opening / closing door 10 is in the closed state, the detection state of the door closing detection sensor 12 transitions from the detection OFF state to the detection ON state (S75).

[0074] When the opening / closing door 10 switches from the open state to the closed state, this switch is detected by the second closing limit detection sensor 15. When the second closing limit detection sensor 15 detects that the opening / closing door 10 has switched from the open state to the closed state, it outputs a detection ON signal to the safety controller 70D. When the safety controller 70D receives the detection ON signal from the second closing limit detection sensor 15 (YES in S76), it activates the stop signal output function (S77). This concludes the explanation of the processes performed by each device when the opening / closing door 10 in the mechanical parking lot P opens and closes according to the fourth embodiment.

[0075] According to the fourth embodiment described above, the safety controller disables the detection information from the door closing detection sensor, and then, when the second closing limit detection sensor detects that the door has switched from an open state to a closed state, it enables the detection information from the door closing detection sensor.

[0076] The facility management system can further enhance safety within the system by installing a second closing limit detection sensor on the opening and closing doors. Furthermore, when a user operates the opening or closing of a door, the detection information from the door closing detection sensor is disabled to ensure the door is opened and closed reliably. When the door returns to the closed state due to the closing operation, the detection information from the second closing limit detection sensor is re-enabled based on the detection information from the second closing limit detection sensor, ensuring a safe transition for the user.

[0077] 《Fifth Embodiment》 <Configuration of the equipment management system according to the fifth embodiment> Since the configuration of the equipment management system 1E according to the fifth embodiment is the same as that of the equipment management system 1A described in the first embodiment, a detailed explanation of the parts having the same function will be omitted.

[0078] In this embodiment, the safety controller 70E disables the stop signal output function, and then, after a predetermined time has elapsed since detecting that the closing operation of the opening / closing door 10 has started under the control of the operation control unit 50, it enables the stop signal output function.

[0079] <Operation of the equipment management system according to the fifth embodiment> This section describes the processes performed by each device in the equipment management system 1E when the opening and closing door 10 in the mechanical parking garage P opens and closes. In this embodiment, 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 the user closes the door are the same as the processes in steps S1 to S24 described in the first embodiment, so a detailed explanation is omitted.

[0080] Figure 9 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 opening / closing door 10 is in the fully open state and the user performs a door closing operation at the operation reception unit 40 to close the opening / closing door 10, the operation reception unit 40 transmits a door closing command to the operation control unit 50.

[0081] When the operation control unit 50 receives a door closing command from the operation reception unit 40 or the like (YES in S81), it transmits operation information to the safety controller 70E indicating that the opening / closing door 10 should be closed (S82). Based on the operation information obtained from the operation control unit 50, the safety controller 70E recognizes that the door closing operation of the opening / closing door 10 has started (S83).

[0082] When the operation control unit 50 receives a door closing command from the operation reception unit 40 or the like, it further transmits a door closing command for the opening / closing door 10 to the power control unit 30 (S84). Based on the door closing command from the operation control unit 50, the power control unit 30 transmits an operation signal to the first power unit 11 to close the opening / closing door 10 (S85). Based on the operation signal obtained from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "stopped" to "operating" and starts the door closing operation (S86).

[0083] When the first closing limit detection sensor 14 detects that the opening / closing door 10 is fully closed, it outputs a detection ON signal to the operation control unit 50. When the operation control unit 50 receives the detection ON signal from the first closing limit detection sensor 14 (YES in S87), it outputs an operation stop command to the power control unit 30 (S88). When the power control unit 30 receives the operation stop command from the operation control unit 50, it sends a stop signal to the first power unit 11 to stop its operation (S89).

[0084] Based on the stop signal received from the power control unit 30, the first power unit 11 of the opening / closing door 10 switches from "operating" to "stopped" and stops the door opening operation (S90). When the opening / closing door 10 is in the closed state, the detection state of the door closing detection sensor 12 transitions from the detection OFF state to the detection ON state (S91).

[0085] On the other hand, after the safety controller 70E disables the stop signal output function, if a predetermined time has elapsed since step S83 when it detects that the closing operation of the opening / closing door 10 has started under the control of the operation control unit 50 (YES in S92), it enables the stop signal output function (S93). This predetermined time is set in advance based on the time it takes for the opening / closing door 10 to go from the fully open state to the fully closed state by the first power unit 11. This predetermined time can be changed as appropriate. This concludes the explanation of the processes performed by each device when the opening / closing door 10 in the mechanical parking lot P is opened and closed according to the fifth embodiment.

[0086] According to the fifth embodiment described above, the safety controller disables the detection information from the door closing detection sensor, and then, after a predetermined time has elapsed since the operation control unit has detected that the closing operation of the opening and closing door has started, it enables the detection information from the door closing detection sensor.

[0087] This allows the facility management system to reliably switch to a state that ensures user safety by disabling the detection information from the door closing detection sensor when a user operates the door to open or close it, and then re-enabling the detection information from the door closing detection sensor when the door returns to the closed state due to the closing operation.

[0088] In the first to fifth embodiments described above, a single power control unit 30 is installed within the equipment management systems 1A, 1B, 1C, 1D, and 1E, and this power control unit 30 controls multiple pieces of equipment. However, multiple power control units may be provided for each piece of equipment to be controlled. For example, a power control unit dedicated to controlling the operation of the opening and closing door 10 may be provided separately, as well as a power control unit for the lift, which is equipment other than the opening and closing door 10. In this case, the first power unit 11 is connected to the power control unit dedicated to the door, and the second power unit 21 is connected to the power control unit for the lift.

[0089] While embodiments of the present invention have been described above, it is possible to modify or alter 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.
