Japanese Unexamined Patent Publication No. 2009-79457

The emergency power supply device is configured by mounting a standby power supply consisting of a battery and electronic components such as an inverter device. External devices such as an automatic closing device for an opening / closing device, an obstacle detection device, a harm prevention interlocking repeater, an operation switch equipped with a start button, and a hydraulic switch, and an external power supply line are connected to this emergency power supply device. There is.

When the power supply from the external power supply line is stopped due to a power outage or the like, the emergency power supply device is in a state where it can supply power to the external device at any time simply by switching the power supply source from the commercial power supply to the standby power supply. .. Therefore, if the power supply from the external power supply line is stopped due to a power failure, etc., and the start button of the emergency power supply device is artificially operated, or if the operation signal from the hydraulic switch is input to the emergency power supply device, the emergency power supply is used. It was configured so that operating power was instantly supplied from the device to the external device.
However, if the start button is operated in about 3 to 10 seconds after a power failure, the operation signal from the hydraulic switch is input, or if some external devices are using an inverter device, etc., the output is output. There was a possibility that the external device on the side would not start normally. This is because in the case of inverter equipment, it is necessary to discharge for a certain period of time from the time of power failure to the time of power recovery.

The present invention has been made in view of the above points, and is an emergency power supply device and an opening / closing body capable of supplying operating power from an emergency power supply device to an external device in a state where the operation of the external device is stable after a power failure. To provide the equipment.

The first feature of the emergency power supply device of the present invention is in an emergency power supply device configured to supply electric power to an external inverter means in response to an input of a start signal generated in response to an artificial operation at the time of a power failure. The power is supplied to the inverter means after the lapse of the first predetermined time from the time when the start signal is input.
The start signal generated by artificial operation includes, for example, the start signal generated when the start button of the emergency power supply provided on the operation switch of the opening / closing stop such as the opening / closing device is operated, or the start signal in the event of a fire. There is a start signal from the water pressure switch that is operated by water being sent (injected) from the fire extinguishing hose. Since these activation signals are generated in response to human operation, the time of occurrence is unknown. Therefore, when these start signals are input when power is supplied to the inverter means in the event of a power failure, a constant discharge required for a first predetermined time from the input time, for example, from the power failure of the inverter means to the restoration of power. The time corresponding to the time was timed, and the power was supplied to the inverter means after the lapse of the first predetermined time. As a result, the discharge time of the inverter means can be sufficiently secured, and the inverter means can be started normally. Even when the emergency power supply device stops supplying the operating power to the external device , the same processing is performed in the event of a power failure, and the operation is performed so as to secure a sufficient discharge time of the inverter means.

The second feature of the emergency power supply device of the present invention is that in the emergency power supply device according to the first feature, the power is automatically supplied to the inverter means after a second predetermined time has elapsed from the occurrence of the power failure. If the start signal is input before the second predetermined time has elapsed, the power is supplied to the inverter means after the first predetermined time has elapsed.
This is a case where the emergency power supply device is automatically started after the second predetermined time has elapsed from the time of the power failure, and when the start signal input time is before the second predetermined time has elapsed, the first from the start signal input time. The power is not supplied to the inverter means until the predetermined time of 1 has elapsed. As a result, by not supplying electric power to the inverter means from the time when the start signal is input until the first predetermined time elapses, it is possible to secure a sufficient discharge time of the inverter means and start the inverter means normally. It will be possible.

The third feature of the emergency power supply device of the present invention is that in the emergency power supply device according to the first feature, the power is automatically supplied to the inverter means after a second predetermined time has elapsed from the occurrence of the power failure. If the start signal is input before the second predetermined time has elapsed, the power is supplied to the inverter means after the second predetermined time has elapsed.
This is a case where the emergency power supply device is automatically started after the second predetermined time has elapsed from the time of the power failure, and when the start signal input time is before the second predetermined time has elapsed, it is related to the input of the start signal. The power is supplied to the inverter means after the lapse of the second predetermined time. Since the power is supplied after the second predetermined time has elapsed from the time of the power failure, it is not necessary to time the first predetermined time in response to the input of the start signal, and the discharge time of the inverter means should be sufficiently secured. This makes it possible to start the inverter means normally. It should be noted that, after the second predetermined time has elapsed from the occurrence of the power failure and the power failure is still in progress, after the emergency power supply device has stopped supplying power to the inverter means, it is extremely difficult until Y seconds have elapsed after the start signal is input. It is preferable to handle the power supply so as not to restart it.

The fourth feature of the emergency power supply device of the present invention is that in the emergency power supply device described in the second feature, when the start signal is input before the second predetermined time elapses, when the power failure occurs. The purpose is to supply the power to the inverter means after a time corresponding to a value obtained by subtracting the elapsed time from the first predetermined time has elapsed.
This is a case where the emergency power supply device is automatically started after the second predetermined time has elapsed from the time of the power failure, and when the start signal input time is before the second predetermined time has elapsed, the start signal is started from the time of the power failure. By subtracting the elapsed time up to the input time point from the first predetermined time and supplying power to the inverter means after the time corresponding to the subtracted value has elapsed, the power is supplied after the first predetermined time has elapsed from the time of the power failure. Since the power can be supplied, the discharge time of the inverter means can be sufficiently secured, and the inverter means can be started normally. If the emergency power supply unit stops supplying power to the inverter means during a power failure, the emergency power supply unit should not be restarted until Y seconds have passed after the start signal was input, without performing subtraction processing. To process.

The fifth feature of the emergency power supply device of the present invention is that in the emergency power supply device according to the first, second, third or fourth feature, the start signal is an start button of an artificially operated operation switch. It is a signal from or an operation signal from a hydraulic switch.
This is because the start signal is a start signal generated when the start button of the emergency power supply provided on the operation switch of the open / close stop of the switch is operated, or water is sent (injected) from the fire extinguishing hose in the event of a fire. It is clarified that it is a start signal from the hydraulic switch operated by it.

The first feature of the opening / closing device of the present invention is the opening / closing means provided at the peripheral edge of the opening by supplying electric power to the inverter means in response to the input of the start signal generated in response to the human operation at the time of a power failure. In an opening / closing device provided with an emergency power supply device configured to control the opening / closing operation of the inverter, the power is supplied to the inverter means after a lapse of a first predetermined time from the time when the start signal is input. There is something in it.
This is an invention of an opening / closing body device corresponding to the first feature of the emergency power supply device.

The second feature of the switchgear device of the present invention is that in the switchgear device according to the first feature, the power is automatically supplied to the inverter means after a second predetermined time has elapsed from the occurrence of the power failure. If the start signal is input before the second predetermined time has elapsed, the power is supplied to the inverter means after the first predetermined time has elapsed.
This is an invention of an opening / closing body device corresponding to the second feature of the emergency power supply device.

The third feature of the switchgear of the present invention is that in the switchgear device according to the first feature, the power is automatically supplied to the inverter means after a second predetermined time has elapsed from the occurrence of the power failure. If the start signal is input before the second predetermined time has elapsed, the power is supplied to the inverter means after the second predetermined time has elapsed.
This is an invention of an opening / closing body device corresponding to the third feature of the emergency power supply device.

The fourth feature of the opening / closing device of the present invention is that when the activation signal is input before the lapse of the second predetermined time in the opening / closing device according to the second feature, the power failure occurs. The purpose is to supply the power to the inverter means after a time corresponding to a value obtained by subtracting the elapsed time from the first predetermined time has elapsed.
This is an invention of an opening / closing body device corresponding to the fourth feature of the emergency power supply device.

The fifth feature of the opening / closing device of the present invention is that in the opening / closing device according to the first, second, third or fourth feature, the activation signal is an activation button of an artificially operated operation switch. It is a start signal from or an operation signal from a hydraulic switch.
This is an invention of an opening / closing body device corresponding to the fifth feature of the emergency power supply device.

According to the present invention, there is an effect that the operation power can be supplied from the emergency power supply device to the external device after a power failure in a state where the operation of the external device is stable.

It includes a switch 19, an emergency power supply device 20, an obstacle detector 185, a hydraulic switch 30, and the like. Normally, the opening / closing body device 10 drives a motor 17 which is an opening / closing machine to control opening / closing in response to an operation of the operation switch 19. Further, in the opening / closing body device 10, the shutter curtain 12 is held in an open state wound around the take-up shaft 15 by a mechanical holding mechanism (not shown), and in this open state, a fire is generated from the outside. When an emergency signal BS or the like indicating generation is input to the control device 18, the holding of the open state by the holding mechanism is released, and the shutter curtain 12 naturally descends under its own weight to automatically close the opening. Has the ability to

It is composed of a metal member having a member or a member equivalent thereto. The shutter curtain 12 rises and falls along the guide grooves of the guide rails 13 and 14, and opens and closes the opening.

The take-up shaft 15 is rotatably provided on both end sides of the shutter case 11 to take up and rewind the shutter curtain 12. The chain 16 connects a main sprocket provided on the rotation shaft of the motor 17 and a driven sprocket provided on the rotation shaft of the take-up shaft 15. Therefore, the rotational driving force of the motor 17 is transmitted to the take-up shaft 15 side via the chain 16, and when the motor 17 rotates, the take-up shaft 15 rotates via the chain 16 and the shutter curtain 12 opens and closes. It is designed to be controlled.

The motor 17 is provided with a position detecting device (not shown) for detecting the rotational position, that is, the open / closed position and the open / closed state of the shutter curtain 12. This position detection device is composed of a pulse generation type rotary encoder or the like. Since a pulse signal corresponding to the rotation of the motor 17 is output to the control device 18, the rotation position of the motor 17 and the position at the opening of the closed end of the shutter curtain 12 are determined by the control device based on the generation status of this pulse. 18 will be calculated.

The control device 18 has a microcomputer configuration, and power is supplied from the power supply line AC via the emergency power supply device 20. The control device 18 controls the rotation of the motor 17 based on a control signal corresponding to the operation state of each operation button on the operation switch 19, a signal from a position detection device provided on the motor 17, a signal from a protector, and the like. Or, the holding mechanism is released based on the emergency signal BS.

The operation switch 19 has an ascending (open) button 19A, a stop (stop) button 19B, and a descending (closed) button 19C as control switches corresponding to each operation of opening / closing, and corresponds to the operation state of each of these buttons. The control signal is output to the control device 18. Further, although not shown, the operation switch 19 outputs an operation switch for outputting an operation signal for operating the automatic closing function, and outputs a recovery signal for canceling the signal by the operation switch to restore the automatic closing function. It is provided with a recovery switch for switching, a start button for outputting a start signal for activating the emergency power supply device 20, a release switch for releasing a transfer signal output from the emergency power supply device 20, and the like.

The emergency signal BS is a signal having a voltage of 24 [V] supplied from an external control room or the like in an emergency such as a fire, and is a harm prevention interlocking repeater in the control device 18 (not shown in FIG. 1). Is entered in. It should be noted that a temperature detector or the like may be provided in combination with the input of the emergency signal BS from the outside, or instead, in the vicinity of the opening of the magnifying glass portion, that is, in the portion where the shutter curtain 12 moves up and down, inside the shutter case 11. good. As this temperature detector, the contact is always on, and when the contact reaches a predetermined temperature (arbitrary temperature in the range of 100 to 300 degrees Celsius), the contact is opened and turned off. 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. It may be configured or configured to output a sensed signal from the tape switch to the control means by wire. In addition, a phototube, LED, or other light-receiving sensor may be provided at the opening to detect obstacles in a non-contact manner by image recognition or the like.

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 the water pressure at which the water pressure switch 30 is operated 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 a DC or AC voltage switched by the emergency power supply device 20 by inputting an input disconnection signal indicating an input disconnection of a commercial power source from the power supply line and supplied via 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 a DC or AC voltage from the output circuit 204 of the emergency power supply device 20. The switch control device 181 has a built-in inverter circuit for converting a DC or AC voltage 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 backup 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 opens and closes by inputting an input disconnection signal indicating the input disconnection of the commercial power supply from the power supply switching circuit 201, thereby converting the DC voltage from the standby power supply 203 as it is or converting it into an AC voltage according to the type of the inverter circuit. It is supplied to an external device such as the machine control device 181. That is, the output circuit 204 can supply a DC or AC voltage according to the specifications of the external device that supplies power. 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 204 supplies the DC voltage from the standby power supply 203 to the inverter circuit of the switch control device 181. Further, in the case of the type in which the inverter circuit inputs an AC voltage and converts it into a predetermined AC voltage, the output circuit 204 converts the DC voltage from the backup power supply 203 into an AC voltage, and the inverter of the switch control device 181. Supply to the circuit.

FIG. 3 is a flowchart showing an example of processing after a power failure occurs in the emergency power supply devices of FIGS. 1 and 2. The emergency power supply device starts processing after a power failure, but details of the processing to be executed when the start button of the operation switch 19 is operated immediately after the power failure and the start signal is input or when the operation signal from the hydraulic switch is input. Will be explained.

In step S31, the power switching circuit 201 outputs an input cutoff signal indicating that the input of the commercial power supply is cut off due to the power failure to the output circuit 204, and timer time measurement is performed to measure the elapsed time Ta from the time of the power failure. Start processing.

In step S32, it is determined whether or not the start button of the operation switch 19 is operated to input the start signal. If it is input (yes), the process proceeds to step S35, and if it is not input (no), the next step is performed. The process proceeds to step S33.

In step S33, it is determined whether or not the operation signal from the water pressure switch has been input, and if it has been input (yes), the process proceeds to step S35, and if it has not been input (no), the process proceeds to the next step S34.

In step S34, it is determined whether or not a predetermined time X seconds have elapsed since the power supply switching circuit 201 outputs the input disconnection signal, that is, whether or not the timer value Ta in the above-mentioned timer timing processing is the predetermined time X seconds. If the predetermined time X seconds has elapsed (yes), the process proceeds to the next step S36, and if not (no), the process returns to step S32. In this process, the X second is a time corresponding to the discharge time of the inverter circuit in the switch control device 181, for example, 10 to 60 seconds, which is a value set in advance as a parameter.

In step S35, since it is determined in step S32 that the activation signal is input or in step S33, it is determined that the operation signal is input. Execute the process. Since the start button of the operation switch 19 is artificially operated, its occurrence time is unknown. Similarly, the time of occurrence of the operation signal from the hydraulic switch is unknown. Therefore, in this embodiment, the emergency power supply device 20 is not started until a predetermined time Y seconds has elapsed after the start signal or the operation signal is input. In this process, the Y second is the same value as the X second, that is, 10 to 60 seconds, and is a value for which parameters are set in advance. Since it is unlikely that the start signal of step S32 or the operation signal of step S33 will be input at the same time as the power failure occurs, a value smaller than X seconds may be set for Y seconds.

In step S36, X seconds have elapsed immediately after the start of the power failure, or Y seconds have elapsed after the input of the start signal or the operation signal, so that the emergency power supply device 20 is started.
In step S37, for example, various processes such as a process interrupted by a power failure, an opening / closing / stopping process of the shutter curtain 12 corresponding to each switch of the operation switch 19, and an emergency opening process corresponding to the operation signal of the hydraulic switch are executed.
In step S38, when the shutter curtain 12 is fully opened or fully closed, or when the operation switch 19 is stopped by pressing (on) the stop (stop) button 19B, the emergency power supply device 20 operates with respect to the external device. Stop the power supply.
In step S39, it is determined whether or not the power failure has ended. If the power failure ends (yes), the process ends, if the power failure state (no), the process returns to step S32, and the processes of steps S32 to S39. repeat. As a result, even if the emergency power supply device 20 stops supplying the operating power to the external device, the emergency power supply device 20 is restarted until Y seconds have elapsed after the input of the start signal or the work signal. It is possible to secure a sufficient discharge time of the inverter device.

In the above-described embodiment, the case where the emergency power supply device 20 is not started until Y seconds have elapsed after the input of the start signal or the operation signal in the processes of steps S32, S33, and S35 has been described. Instead of the Y-second timekeeping process, the elapsed time Ta seconds after a power failure during timekeeping may be subtracted from the Y seconds by the timer time-keeping process in step S31, and the timed process may be performed by the subtracted value (Y—Ta) seconds. In this case, since Ta seconds have passed after the power failure, it is possible to discharge the inverter device for Y seconds for a certain period of time by delaying by a time corresponding to the subtraction value (Y—Ta) seconds. be. Further, when the subtraction value (Y—Ta) seconds is negative, Y seconds have elapsed after the power failure, so that the process may proceed to step S36 and the emergency power supply device 20 may be started without timing processing. Here, when X seconds and Y seconds are the same value, the emergency power supply device 20 is started after a predetermined time X seconds (or Y seconds) has elapsed after the occurrence of the power failure.

In the above-described embodiment, the emergency power supply device is automatically started after a predetermined time and X seconds have elapsed after the occurrence of a power failure, and when the start signal or the operation signal is input before the predetermined time and X seconds have elapsed, the emergency power supply device is automatically started. The case where the emergency power supply device is started Y seconds after the signal is input has been described, but the emergency power supply device is started after a predetermined time X seconds have elapsed after the occurrence of a power failure, and the processing corresponding to the start signal or the operation signal is performed. You may want to do it. In this case, the process of step S35 may be omitted, and if the determination result of step S32 and step S33 is yes, the process may proceed to step S34. Further, if the emergency power supply device 20 stops supplying the operating power to the external device during a power failure, the emergency power supply device 20 should not be restarted until Y seconds have elapsed after the input of the start signal or the work signal. The same process as in step S35 may be executed. The X seconds and Y seconds may be fixedly stored in advance in a memory (not shown) provided in the emergency power supply device 20, or may be stored in the memory from an input from an operation switch or an external storage device such as a USB memory. You may respond by letting it.

In the above-described embodiment, the case where the emergency power supply device is automatically started after a predetermined time and X seconds have elapsed after the occurrence of a power failure has been described, but the start signal or the operation signal is also similarly when the emergency power supply device is not automatically started. The emergency power supply device may be started after Y seconds have elapsed since the input of. In this case, the processing of step S31 and step S34 in FIG. 3 may be omitted, and if the determination result of step S33 is no, processing may be performed so as to return to step S32.

In the above-described embodiment, the shutter curtain that is extended by the vertical elevating method has been described as an example, but the same applies even if the shutter-shaped opening / closing member is extended by the horizontal pulling method or the horizontal method. Can be applied to. Further, as the opening / closing body device, for example, it can be applied to a shutter device, a window shutter device, a blind device, a roll screen device, a hanging curtain device, a sliding door device, a moving partition device, an awning device, a waterproof plate device, and the like.
