It is composed of a high temperature bimetal thermostat or the like, and when a contact is opened, a signal indicating that a fire or the like has occurred is output to the emergency power supply device 20, and a signal corresponding to the emergency signal BS is output from the emergency power supply device 20. You may try to do it.

The obstacle detector 185 has a transmitter provided at the lower end (seat plate) of the shutter curtain 12, and when an obstacle is detected, a sensing signal corresponding to the movement of the built-in seat plate switch is transmitted to the control device 18. It is configured to transmit, and when the return movement of the seat plate switch is performed by removing obstacles thereafter, a return signal is transmitted. The transmission of the signal from the transmitter of the obstacle detector 185 to the control device 18 is not limited to the wired method as shown in the figure, but may be a wireless method operated by using a battery as a power source. Further, a seat plate switch that moves by contact with an obstacle is provided at the lower end of the shutter curtain 12, and the tape switch provided along the height direction of the guide rail is pressed by the moving force of the seat plate at the time of contact with the obstacle.

In the water pressure switch 30, a fire extinguishing hose is connected to a water supply port (not shown) provided outside the building, water supply (injection) is started from there, and the water pressure (water flow momentum) is within a predetermined range. It is a switch that operates when the size is inside, and outputs the operation signal to the emergency power supply device 20. The emergency power supply device 20 that has input this operation signal outputs the transfer signal to the obstacle detection device control panel 184. The range of water pressure for operating the water pressure switch 30 is appropriately set in consideration of the assumed water discharge capacity of the fire brigade. A fire extinguishing hose is connected to the water supply port in the event of a fire. The water sent from the water supply port is drained from a drainage port (not shown) via the water pressure switch 30.

FIG. 2 is a diagram showing an outline of a circuit configuration of a control system constituting the switching body device according to the present invention. The control device 18 is controlled by a microcomputer, and includes a switch control device 181, a harm prevention interlocking repeater 182, an automatic closing device 183, and an obstacle detection device control panel 184. The motor 17 and the automatic closing device 183 are controlled by processing signals input from the operation switch 19, obstacle detector 185, hydraulic switch 30, etc., power output from the emergency power supply device 20, and various signals.

The switch control device 181 operates by an AC voltage that is switched by the emergency power supply device 20 and supplied via the power supply line by inputting an input disconnection signal indicating an input disconnection of a commercial power supply from the power supply line. That is, normally, the motor 17 is supplied with power from the commercial power supply, but when the power supply from the commercial power supply is stopped in an emergency such as a power failure, the switch control is performed. The device 181 receives an AC voltage from the output circuit 204 of the emergency power supply device 20. Some switch control devices 181 have a built-in inverter circuit for converting a DC or AC voltage input from a power supply line into a power source according to the rating of the motor 17. This inverter circuit receives a signal indicating shutter position information from the position detection device 172 provided in the motor 17, and controls the conversion operation from the DC voltage to the AC voltage based on the signal. In FIG. 2, the connection relationship of the power supply line to other than the control device 18 is not shown.

The hazard prevention interlocking repeater 182 uses a commercial power supply or an emergency power supply device 20 as a power source for operating the automatic closing device 183 when receiving an operation signal from the emergency signal BS or the operation switch 19. It is output from. The harm prevention interlocking repeater 182 normally outputs using a commercial power source, but outputs a DC 24V signal to the automatic closing device 183 by the electric power from the emergency power supply device 20 in the event of a power failure or the like.

The automatic closing device 183 releases the holding mechanism 171 in response to the DC 24V signal supplied via the harm prevention interlocking repeater 182, lowers the shutter curtain 12 in the winding state by its own weight, and automatically lowers the opening. Works to close. The automatic closing device 183 is configured to project the pressing actuating member by the rotational force of the motor when a DC 24V signal is supplied. The pressing actuating member is arranged so as to press the operating lever of the holding mechanism 171 at its tip. In an emergency, the automatic closing device 183 may lower the shutter curtain 12 by its own weight in response to the operation of the emergency closing button provided on the operation switch 19. The automatic closing device 183 releases the holding mechanism 171 while the DC 24V signal from the harm prevention interlocking repeater 182 is being supplied, but when there is an obstacle detection signal of the obstacle detection device control panel 184, the automatic closing device 183 releases the holding mechanism 171. During that time, the holding mechanism 171 is restored. In some cases, the holding mechanism 171 is restored when the power supply (DC 24V signal) from the harm prevention interlocking repeater 182 is lost.

The emergency power supply device 20 is controlled by a microcomputer, and includes a power supply switching circuit 201, a charging circuit 202, a backup power supply (storage battery) 203, an output circuit 204, and the like. The power switching circuit 201 supplies the commercial power AC supplied via the power line to the switch control device 181 and also supplies power to the charging circuit 202. Further, the power supply switching circuit 201 outputs an input disconnection signal indicating that the commercial power supply is disconnected to the output circuit 204 when the input disconnection of the commercial power supply AC supplied from the power supply line is detected. .. The charging circuit 202 charges the standby power supply (storage battery) 203 using the electric power supplied from the power supply switching circuit 201. The standby power supply (storage battery) 203 is composed of a lithium-ion rechargeable battery and other batteries (including a power supply of a type that can be used up like a dry battery as well as a rechargeable battery), and is controlled by an switch via an output circuit 204 in the event of a power failure. Power is supplied to the device 181 and the like.

The output circuit 204 uses the DC voltage from the standby power supply 203 as it is by inputting an input disconnection signal indicating the input disconnection of the commercial power supply from the power supply switching circuit 201, or uses an inverter circuit according to the specifications of the connected external device. It is converted to a predetermined AC voltage and supplied. That is, the output circuit 204 has a built-in inverter circuit and can supply an AC voltage according to the specifications of the external device. Since the inverter circuit has a built-in internal memory that operates when an AC voltage is generated, the emergency power supply device 20 determines whether or not there is an abnormality in this internal memory (Read / Write test, March-C test, etc.). Is always done. Normally, power is supplied from the commercial power supply to the switch control device 181. However, when the power supply from the commercial power supply is stopped in an emergency such as a power failure, the output circuit is used. The inverter circuit of 204 converts the DC voltage of the standby power supply 203 into an AC voltage and supplies it to the switch control device 181.

FIG. 3 is a flowchart showing an example of processing of the emergency power supply device of FIGS. 1 and 2.
In step S31, the emergency power supply device 20 executes an abnormality determination test of the internal memory at the start of processing. The abnormality determination test is a simple memory test in which predetermined pattern data or predetermined parameters are written in the internal memory for operating the inverter circuit of the emergency power supply device 20, read out, and compared with the expected value.

In step S32, if the result of the memory abnormality determination test in step S31 is normal (yes), the process proceeds to the next step S33, and if the result is abnormal (no), the process proceeds to step S34. It should be noted that this abnormality determination test may be executed a plurality of times rather than once, and the determination may be made according to the number of times when an abnormality occurs in the plurality of times. For example, when it is executed multiple times, if there is an abnormality even once, it may be judged as abnormal, and if it is abnormal only for the first time and the normality continues after that, it is regarded as normal. The determination may be made, and the abnormal and normal determination methods can be carried out in various embodiments.

In step S33, the normal operation of the emergency power supply device 20 is executed. Here, when the operation signal from the hydraulic switch 30 is input, the emergency power supply device 20 operates so as to supply operating power to the external device, and outputs the transfer signal to the obstacle detection device control panel 184. .. The operating power output from the emergency power supply device 20 is a commercial power supply (for example, AC100 [V] or AC200 [V], etc.) in a normal time when a power failure does not occur, and an emergency power supply in an emergency when a power failure occurs. The power of the standby power supply (storage battery) 203 of the device 20 is converted into alternating current by the inverter circuit in the output circuit 204 and supplied.

In step S34, since it is determined that the memory is abnormal in step S31, it is determined whether or not the commercial power is normally supplied, that is, whether or not the commercial power input is cut off due to a power failure or other reasons, and the commercial power is turned on. If it is normal (yes), the process proceeds to step S35, and if the commercial power is not normally supplied (no), the process proceeds to step S36.

In step S35, there was a memory error in the internal memory abnormality determination test, but since the commercial power supply is normally supplied, the parameters set arbitrarily in the internal memory and stored are returned to the initial values, and the commercial power supply is used. Executes the output operation by and ends the processing.
In step S36, a memory abnormality is determined in the internal memory abnormality determination test in step S32, and a commercial power supply abnormality (input disconnection) is determined in step S34. Therefore, processing is performed here without operating the emergency power supply device 20. To finish. If it is determined that the memory is abnormal, it may be stored in a predetermined memory so that it can be read by a tester or the like, or it may be notified to the outside by lighting a lamp or the like.

In step S34, it is determined whether or not the commercial power is normally supplied, but at the same time, it is determined whether or not other fatal abnormality has occurred, and only when it has not occurred. You may proceed to step S35. Examples of the fatal abnormality here include disconnection of the signal line in the emergency power supply device 20 or the signal line connected to the external device.
