The present invention relates to an emergency power supply device for supplying power to a body device and a switchgear device.

  Opening and closing devices such as shutter curtains are installed at the opening or window of a structure frame including a building such as a house, a building, a factory, a warehouse, a garage, etc. or an opening such as an internal passage or space. By moving the body, the opening is opened and closed. This opening / closing device includes a slat curtain made of a large number of strip-like slats, a pipe grille curtain formed by connecting a large number of pipe members by a link material or the like, a panel curtain made of one or more connected panel materials, The opening and closing member such as a net curtain made of a net material, a sheet curtain made of a sheet material made of synthetic resin or cloth fiber, or a composite curtain made of these composite members is drawn down from the upper part of the opening to lower the entire opening It is configured to close.

JP, 2009-79457, A

  The emergency power supply device is equipped with a backup power supply composed of a battery, and is configured to include electronic components such as an inverter circuit for converting direct current or alternating current voltage into power according to the rating of the motor. The emergency power supply device is connected to external devices such as an automatic closing device for opening and closing body device, an obstacle detection device, an interlock relay for hazard prevention, an operation switch with a start button and a water pressure switch, an external power supply line, etc. There is.

  When the power supply from the external power supply line is interrupted due to a power failure or the like, the emergency power supply device is ready to 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, when the power supply from the external power supply line is stopped due to a power failure, etc., the emergency power supply is operated artificially, or the operation signal from the water pressure switch is input to the emergency power supply. The device is configured to supply operating power to an external device.

  Some emergency power supply devices are configured to be capable of sequentially controlling two opening / closing devices. As described above, in the case of raising the two switchgear devices with one emergency power supply device, it is possible to simultaneously raise the two units at the time of startup by the commercial power supply, but the standby power supply was used as during a power failure. In the inverter circuit, it is often difficult to raise the switch devices simultaneously. Therefore, the output destinations are switched at fixed time intervals to alternately raise the two switch devices.

  When two opening / closing devices are installed in the opening of the same size, it is possible to open the opening almost at the same time by alternately switching and raising at regular time intervals. However, in the case where shutters having different rising speeds, such as a normal shutter device and a high-speed shutter device, are alternately raised for a predetermined time, the high-speed shutter device may reach the upper limit first. However, since the output to the shutter is alternately output at regular time intervals, control has been performed to wastefully output power at regular time intervals also to the high-speed shutter device that does not need to be raised. This similarly causes the shutter with the smaller opening to reach the upper limit first when the same specification is installed in the openings of different sizes.

  The present invention has been made in view of the above-described point, and efficiently opens the opening / closing device when supplying power for operation from one emergency power supply device to a plurality of opening / closing devices after a power failure. It is an object of the present invention to provide an emergency power supply device and a switchgear device that can be performed.

  According to a first feature of the emergency power supply device of the present invention, a plurality of open / close members respectively installed in a plurality of openings by sequentially switching for each predetermined switching time at the time of a power failure and supplying power to the plurality of opening / closing driving means In the emergency power supply apparatus configured to sequentially open, the switching time is set based on the size of the opening in the moving direction of the opening / closing body and the moving speed of the opening / closing body.

  Some emergency power supplies are configured to be able to control two or more switchgear devices. For example, in the case of lifting the two switchgear devices with one emergency power supply device, it is possible to simultaneously lift the two devices at the time of activation by the commercial power supply. However, in an inverter circuit using a standby power supply as in the event of a power failure, it has been difficult to simultaneously raise the switchgear device. Therefore, conventionally, the output destination is switched every fixed switching time to open and close two units. The body device was being raised alternately.

In the case where control is performed by switching the output destination every fixed switching time, a plurality of opening / closing units are the same size opening, and the moving speed of the opening / closing unit is the same. Although it is effective, if the size of the opening and / or the moving speed of the opening and closing body are different, it may not be efficient to switch and raise at every constant switching time.
So, in this invention, we decided to set the switching time based on the size of the opening in the moving direction of the opening and closing body and the moving speed of the opening and closing body as the switching time.

  For example, assume that the size of the first opening in the moving direction is 3 m, the size of the second opening is 6 m, and the moving speeds of the opening and closing members are the same 3 m / min. . The first opening is one minute to fully open from the fully closed state, and the first opening is two minutes. In order to move the first and second openings alternately by three switching processes and make them fully open, the switching time of the first opening is 20 seconds, and the switching time of the second opening is 40. It will be seconds. When the third opening with a size of 3 [m] in the movement direction is added to this and the switching and raising is performed, the switching time of the third opening is 20 seconds. In addition, in order to move alternately and fully open in the switching process of two times, the switching time of the first and third openings is 30 seconds, and the switching time of the second opening is 60 seconds.

The size of the first opening in the moving direction is 3 m, the moving speed is 3 m / min, the size of the second opening is 6 m, and the moving speed is 6 m / min. ]. Since the time required for the first and second openings to fully open from the fully closed state is both one minute, the switching time of the first and second openings is the same value, and the switching time is 30 seconds in two switchings. The switching time is 20 seconds after switching three times.
Thus, when the power supply for operation is supplied from the one emergency power supply device to the plurality of switchgear devices after the power failure, the opening operation of the switchgear device can be efficiently performed.

  According to a second feature of the emergency power supply device of the present invention, in the emergency power supply device according to the first feature, it is necessary to open the plurality of openings by a predetermined opening amount by the opening operation from the fully closed state. The larger one of the minimum operation times is to be set as one of the switching times.

  Here, the predetermined opening amount is an opening amount of about 1 [m] which a person can pass. In the first opening operation, it is necessary to open (rise) only the predetermined opening amount of about 1 [m]. Therefore, in the present invention, the minimum operation time required to open only a predetermined opening amount from the fully closed state is determined for the plurality of openings from the fully closed state, and the large time is selected from the plurality of minimum operation times. I set it as one.

  For example, the size of the first opening in the movement direction is 3 m, the movement speed is 3 m / min, the size of the second opening is 12 m, the movement speed is 6 m / min ]. The minimum operating time of the first opening is 20 seconds, and the minimum operating time of the second opening is 10 seconds. The time required for the first opening to fully open from the fully closed state is one minute, and the time required for the second opening to fully open from the fully closed state is two minutes. Therefore, assuming that the minimum operating time of the first opening is 20 seconds as the switching time of the first opening, the number of switching times is three times, so the switching time of the second opening is 2 minutes divided by 3 The value is 40 seconds.

  According to a third aspect of the emergency power supply device of the present invention, in the emergency power supply device according to the second aspect, the opening operation is performed first from the opening / closing member of which the smaller time is set as the switching time. It is in.

  The minimum operation time is a time during which the user can open (rise) an open amount of about 1 [m] which can be passed by a person, and is a value depending on the moving speed of the opening and closing body. For example, the size of the first opening in the movement direction is 3 m, the movement speed is 3 m / min, the size of the second opening is 12 m, the movement speed is 6 m / min ]. The minimum operation time of the movement speed of 3 m / min is 20 seconds, and the minimum operation time of the movement speed of 6 m / min is 10 seconds. Assuming that the minimum operating time of the first opening is 20 seconds as the switching time of the first opening, the number of times of switching is three times, so the switching time of the second opening is 40 seconds. Therefore, by performing the opening operation from the opening and closing body with the switching time of 20 seconds first, and then opening the opening and closing body with the switching time of 40 seconds, both of the opening and closing bodies are predetermined in about 30 seconds It is possible to open the opening amount of Conversely, if the opening operation is performed first from the second opening, it takes about 60 seconds for both open / close members to release the predetermined opening amount, which is about 30 seconds or more. It will cause a time delay. As the switching time, executing the opening operation first from the opening / closing member of which the smaller time is set means setting the larger one of the minimum operation times as shown in the third feature. It means that the opening operation is performed first from the closed-loop device 10a of the person who has been.

According to a fourth aspect of the emergency power supply device of the present invention, in the emergency power supply device according to the first, second or third aspect, the openings are present at two places, and the two openings are respectively provided The opening and closing drive means and the opening and closing body are provided to alternately open the opening and closing body according to the switching time set to different values.
This is limited to the case where the opening and closing drive means and the opening and closing member are provided individually at the two openings.

The first feature of the opening and closing device according to the present invention is that the plurality of opening and closing drive units are provided by switching sequentially at predetermined switching time and supplying electric power to the plurality of opening and closing driving means. In the opening and closing device provided with an emergency power supply device configured to open the opening and closing body sequentially, the switching time is based on the size of the opening in the movement direction of the opening and closing body and the moving speed of the opening and closing body. The time is to set.
This is an invention of a switchgear device corresponding to the first feature of the emergency power supply device.

According to a second aspect of the opening / closing device of the present invention, in the opening / closing device according to the first aspect, the plurality of openings are opened from the fully closed state by a predetermined opening amount as the switching time. Setting the larger one of the minimum operating times necessary for the switching time as one of the switching times.
This is an invention of a switchgear device corresponding to the second feature of the emergency power supply device.

According to a third aspect of the opening / closing device of the present invention, in the opening / closing device according to the second aspect, the opening operation is performed first from the opening / closing member set with a smaller time as the switching time. It is in.
This is an invention of a switchgear device corresponding to the third feature of the emergency power supply device.

According to a fourth aspect of the switchgear device of the present invention, in the switchgear device according to the first, second or third feature, the opening is present in two places, and the opening / closing drive is performed in each of the openings Means and the opening and closing body are provided, and the opening and closing body is alternately opened according to the switching time.
This is an invention of a switchgear device corresponding to the fourth feature of the emergency power supply device.

  According to the present invention, there is an effect that the opening operation of the opening / closing device can be efficiently performed when the operation power is supplied from one emergency power supply device to the plurality of opening / closing devices after a power failure.

In addition to or in place of the input of the emergency signal BS from the outside, a temperature sensor or the like is located inside the shutter cases 11a and 11b and in the vicinity of the opening of the lintel, ie, the portion where the shutter curtains 12a and 12b move up and down. May be provided. As this temperature sensor, the contact point is always in the on state, and when the contact reaches a predetermined temperature (arbitrary temperature in the range of 100 to 300 degrees Celsius), the contact is opened and the contact is turned off automatically. It consists of a high-temperature bimetal thermostat etc. and outputs a signal indicating that a fire etc. has occurred to the emergency power supply 20 when the contacts are opened, and outputs a signal corresponding to the emergency signal BS from the emergency power supply 20 You may do it.

The emergency power supply device 20 which has received this operation signal outputs a transfer signal to the obstacle detector control panel 184a. 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 hose is connected to the water supply port at the time of fire or the like. The water supplied from the water supply port is drained from a drain 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 that constitutes the opening / closing device according to the present invention. The control device 18a is controlled by a microcomputer, and includes a switch control device 181a, a safety interlocking relay 182a, an automatic closing device 183a, and an obstacle sensing device control panel 184a. The motor 17a and the automatic closing device 183a are controlled by processing the signals input from the operation switch 19a, the obstacle sensor 185a, the water pressure switch 30, etc. and the power and various signals output from the emergency power supply device 20. The control device 18b has the same configuration as the control device 18a, so the control device 18a will be described, and the illustration and description of the control device 18b will be omitted.

  The switch control device 181a is operated by the AC voltage which is switched by the emergency power device 20 and supplied via the power line by inputting an input disconnection signal indicating the input disconnection of the commercial power from the power line. That is, although the electric power from the commercial power supply is normally supplied to the motor 17a, the switch control is performed when the power supply from the commercial power supply is interrupted in an emergency such as a power failure. The device 181 a is adapted to receive the supply of an alternating voltage from the output circuit 204 of the emergency power supply device 20. Some switchgear control devices 181a incorporate an 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 17a. The inverter circuit receives a signal indicating shutter position information from the position detection device 172a provided in the motor 17a, and controls the conversion operation from DC voltage to AC voltage based thereon. In FIG. 2, the illustration of the connection relationship of the power supply lines other than the control device 18 a is omitted.

  When the hazard interlocking relay 182a receives the emergency signal BS or the operation signal from the operation switch 19a, the power source (for example, DC 24 V etc.) for operating the automatic closing device 183a becomes a commercial power or emergency power unit 20. Output from The hazard interlocking relay 182a normally outputs power using a commercial power source, but outputs a DC 24 V signal to the automatic closing device 183a by the power from the emergency power supply device 20 at the time of a power failure or the like.

  The automatic closing device 183a releases the holding mechanism 171a in response to the DC 24V signal supplied via the hazard interlocking relay 182a, and lowers the shutter curtain 12a in the winding state by its own weight to automatically open the opening. Act to close. The automatic closing device 183a is configured to cause the pressing actuating member to protrude by the rotational force of the motor when a direct current 24 V signal is supplied. The pressing and operating member is disposed so as to press and operate the operation lever of the holding mechanism 171a at its tip end. In an emergency, the automatic closing device 183a may lower the shutter curtain 12a by its own weight in response to the operation of the emergency closing button provided on the operation switch 19a. The automatic closing device 183a releases the holding mechanism 171a while the 24 VDC signal from the hazard interlocking relay 182a is supplied, but when there is an obstacle sensing signal of the obstacle sensing device control panel 184a Meanwhile, the holding mechanism 171a is returned. In some cases, the holding mechanism 171a is returned when the power supply (24 VDC signal) from the hazard interlocking relay 182a 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 standby power supply (storage battery) 203, an output circuit 204, and the like. The power supply switching circuit 201 supplies commercial power AC supplied via the power supply line to the switch control device 181 a and supplies power to the charging circuit 202. Further, the power supply switching circuit 201 outputs an input interruption signal indicating that the input of the commercial power supply has been interrupted to the output circuit 204 when it is detected that the input interruption of the commercial power supply AC supplied from the power supply line has occurred. . The charging circuit 202 charges the standby power supply (storage battery) 203 using the power supplied from the power supply switching circuit 201. The standby power supply (storage battery) 203 includes a lithium ion rechargeable battery and other batteries (including a power supply that can be used up like a dry battery as well as rechargeable batteries), etc. Power is supplied to the device 181a and the like.

  The output circuit 204 receives an input disconnection signal indicating disconnection of the commercial power from the power switching circuit 201, converts the DC voltage from the standby power supply 203 as it is or converts it into an AC voltage according to the type of the inverter circuit, and opens or closes it. It supplies the external device such as the machine control device 181a. That is, the output circuit 204 can supply direct current or alternating current voltage according to the specification of the external device that supplies power. Normally, power from the commercial power supply is supplied to the switch control unit 181a, but the output circuit is used when the power supply from the commercial power supply is interrupted in an emergency such as a power failure. A power supply 204 supplies a DC voltage from the auxiliary power supply 203 to the inverter circuit of the switch control device 181a. When the inverter circuit of the switch control device 181a is of the type that receives 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 switches it. It supplies to the inverter circuit of the machine control device 181a.

  FIG. 3 is a flowchart showing an example of processing after occurrence of a power failure of the emergency power supply device of FIGS. 1 and 2. Although the emergency power supply device starts processing after a power failure occurs, details of processing executed when an operation signal from the water pressure switch 30 is input immediately after the power failure will be described.

In step S31, the power supply switching circuit 201 outputs, to the output circuit 204, an input interruption signal indicating that the input of the commercial power supply has been interrupted due to the power failure.
In step S32, the timer is reset.

In step S33, an emergency release process corresponding to the operation signal from the water pressure switch 30 is performed on the opening / closing device 10a serving as the first shutter.
In step S34, it is determined whether or not the timer has elapsed for X seconds. If it has elapsed (yes), the process proceeds to the next step S35. If it has not elapsed (no), the process proceeds to step S33 until X seconds have elapsed. Continue the emergency release process.

In step S35, the timer is reset.
In step S36, an emergency release process corresponding to the operation signal from the water pressure switch 30 is performed on the opening / closing device 10b serving as the second shutter.
In step S37, it is determined whether or not the timer has elapsed Y seconds. If it has elapsed (yes), the process proceeds to the next step S38. If it has not elapsed (no), the process proceeds to step S36 until Y seconds has elapsed. Continue the emergency release process.
In step S38, it is determined whether or not the emergency release processing has ended for both the opening / closing device 10a serving as the first shutter and the opening / closing device 10b serving as the second shutter. If yes (Yes), the processing is performed If it is not completed (no), the process returns to step S32, and the processes of steps S32 to S37 are repeatedly executed.

  Here, X seconds and Y seconds are parameters set according to the height of the opening of the opening / closing device 10a, 10b. 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 the operation switch or an external storage device such as a USB memory. You may respond by letting it go. Also, instead of directly storing X seconds and Y seconds, the height of the opening of opening / closing device 10a, 10b, opening / closing speed, opening amount, etc. are stored in memory, and based on these values, the emergency power supply device 20 may perform an operation to calculate X seconds and Y seconds. Normally, the opening / closing speed (moving speed at opening / closing) of the opening / closing device 10a is 3 m / min, and the opening / closing speed of the opening / closing device 10b is 6 m / min. In the case of the emergency opening process corresponding to the operation signal from the water pressure switch 30, it is necessary to open (rise) at least about 1 [m] as an opening amount which a person can pass in the first opening operation. The emergency release processing time X seconds of 10a is 20 seconds or more, and the emergency release processing time Y seconds of the opening / closing device 10b is 10 seconds or more. When the emergency release processing time X seconds of the opening / closing device 10a is 20 seconds, the opening / closing device 10a is fully opened in three opening processes. Therefore, in order to make the opening / closing device 10b fully open in three times of opening processing, the opening height 9 [m] is divided by 3 for the emergency opening processing time Y seconds, and this divided value 3 [m] ] Is further divided by 6 [m / min], that is, 30 seconds.

  The relationship between X seconds and Y seconds is a value depending on the opening / closing speeds Va, Vb [m / min] of the opening / closing device 10a, 10b and the heights Ha, Hb [m] which is the size of the opening. First, at least about 1 [m] needs to be opened (raised / moved) as an opening amount that can be passed by a person in the first opening operation, either (1 / Va) or (1 / Vb) Set to a value greater than or equal to the larger one. Next, when (1 / Va) minutes is determined as the minimum operation time, the switchgear device 10a is fully opened in (Ha / Va) / (1 / Va) = Ha, that is, the above-described operation of Ha times. Therefore, in order to make the open-close device 10b fully open in Ha operations, the operation time of the open-close device 10b is obtained by dividing the opening height Hb by the number of operations Ha and dividing the value further It is obtained by dividing by Vb [m / min].

  In the case of the above embodiment, (1 / Va) minutes is (1/3) minutes = 20 seconds, and (1 / Vb) is (1/6) minutes = 10 seconds, so X seconds and Y seconds It is desirable to set 20 seconds or more as the minimum operation time. Assuming that the minimum operation time X is 20 seconds, the open / close device 10a is fully opened in three operations, so that the open / close device 10b is fully open in three operations. One operation time is a value Y = 30 seconds obtained by dividing the opening height Hb = 9 by the number of operations 3 and dividing the divided value 3 by 6 [m / min]. On the other hand, assuming that the minimum operation time X is 30 seconds, the switchgear device 10a is fully opened in two operations, so in order to fully open the switchgear device 10b in two operations, the switchgear device 10b is One operation time Y of 10b is a value Y = 45 seconds obtained by dividing the opening height Hb = 9 by the number of operations 2 and dividing the divided value by 6 [m / min]. .

  Although the above-mentioned embodiment explained the case where opening and closing speed of opening and closing device 10a and 10b differs, when opening and closing speed are the same, ie, it is assumed that both opening and closing speeds are 3 [m / min]. The emergency release processing time X seconds of the opening / closing device 10a, 10b is 20 seconds or more. When the emergency release processing time X seconds of the opening / closing devices 10a and 10b is 20 seconds, the opening / closing device 10a is fully opened in three opening processes, but the opening / closing device 10b is fully opened in nine opening processes. . Therefore, in order to make the opening / closing device 10b fully open in three times of opening processing, the value of the emergency opening processing time Y seconds is obtained by dividing the opening height 9 [m] by 3 and dividing it 3 [m] Is further divided by 3 [m / min], 60 seconds = 1 minute.

  When the operation times X and Y are determined, the opening and closing operation is started from the smaller value of the opening / closing device. As a result, it becomes possible to secure, in the shortest time, the opening amount that a person can pass as the opening amount of the shutter curtains 12a and 12b of the two opening and closing devices. Further, that the opening operation is started from the open / close device 10a or 10b having the smaller value of the operation time X or Y is the open / close device 10a having the longer one of the minimum operation times set. Means the same as executing the release operation first.

In the above-described embodiment, the case in which two open / close bodies are controlled by one emergency power supply device has been described, but the same applies to the case where three or more open / close bodies are controlled by one emergency power supply device be able to.
In the above-described embodiment, the shutter curtain which is fed out in the vertical direction is described as an example, but the shutter-like opening and closing member may be drawn out in the lateral pulling method or horizontally in the same manner. It can be applied to In addition, as the opening and closing body device, for example, it is also applicable to a shutter device, a window shutter device, a blind device, a roll screen device, a curtain device, a sliding door device, a moving partition device, an awning device, a waterproof plate device and the like.
