Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery diagnosing device in a safety device for an electric shutter for construction which is installed at a doorway of a house, a building or the like. BACKGROUND OF THE INVENTION Generally,
In a building shutter, although the shutter curtain is automatically opened and closed electrically,
For example, in the case of a remote control room, the administrator does not directly monitor the closed state of the shutter curtain when the shutter kern is closed. In such a case, there is a problem that an obstacle such as a person or luggage is caught in the shutter curtain. Therefore, a safety device has already been developed and put into practical use, by providing an obstacle detection switch on the bottom seat of the shutter curtain and urgently stopping the closing operation of the shutter curtain based on the detection operation of the obstacle detection switch. Has been done. By the way, when such an obstacle is detected, it is necessary to notify the switch control unit for opening and closing the shutter curtain of this detection signal, but since the shutter curtain is opened and closed, Wired connection is not preferable, and it is preferable to transmit by wireless transmission of light, radio waves, sound waves or the like. In such a case, the seat plate will be provided with an oscillator for outputting and transmitting an obstacle detection signal, and of course, a power source for starting it, that is, a battery (battery) must also be mounted. By the way, the obstacle detection of the shutter curtain as described above may be performed only when the shutter curtain is lowered, but in view of its importance, it is necessary to always perform stable and reliable obstacle detection. Is required.
One of the factors that impair the reliability is a decrease in battery capacity. The decrease in battery capacity is not only constant due to the power supply to the oscillator, but also due to spontaneous discharge, etc. Therefore, in the past, frequent battery check and battery replacement were required to ensure reliability. However, the maintenance management is not allowed to be troublesome, and it is possible to neglect it. When the battery capacity is low and the battery is out of battery, the shutter curtain is lowered while the obstacle detection signal is not output and transmitted, and the shutter curtain is completely unprotected as a countermeasure against obstacles. Obstacles will be caught by the curtain, and you will eventually notice that you are out of shape. Therefore, when the battery diagnostic device is mounted on the seat plate and the battery falls below a predetermined capacity (capacity that still has a margin to operate the safety device), a battery abnormal signal is generated at any time. It is also proposed to configure to output. However, even if the battery abnormal signal is received when the shutter curtain is fully opened, the seat plate is located at a high place and is swallowed by Magsa and is not exposed to the outside. It will not be exchangeable. Moreover, if the shutter is installed at an entrance / exit where a large number of unspecified people such as banks, train stations, or shops enter and leave, simply lower the shutter curtain for the purpose of battery replacement, and temporarily It is not preferable to stop the entrance and exit, and it is sufficient to replace the battery when the shutter curtain is closed on a daily basis such as when the store is closed, and such maintenance management is required. At that time, when the shutter curtain is fully opened, a battery abnormality signal is issued,
Even if the alarm is activated in response to this, it creates anxiety because it must be ignored until the shutter curtain is closed on a daily basis and the battery is replaced. In such a case, since it is inconvenient for the eyes, the administrator himself may switch off the alarm until the shutter curtain is closed on a daily basis. When I had time, I forgot to cut the switch and neglected to replace the battery.In this case, the battery with reduced capacity was used as it was, and the safety device fell into the inoperable state due to the disconnection of the battery. There is a risk of lowering the shutter curtain in a dangerous state. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances and was devised with the object of providing a remote control device capable of eliminating these drawbacks. An obstacle detection switch that detects obstacles in the descending process of the shutter curtain, and an obstacle detection switch of the obstacle detection switch on the seat plate installed at the bottom end of the shutter curtain that is built in the opening of the building such as the entrance and exit. While a transmitter for transmitting a signal as a radio signal is provided, a receiver for receiving the obstacle detection signal is provided at the building opening, and a shutter curtain for opening and closing the shutter curtain based on the obstacle detection signal from the receiver. A control circuit means for outputting an emergency stop command to the motor is provided to emergency stop the descent of the shutter curtain based on the obstacle detection of the obstacle detection switch. In the safety device for an electric shutter for construction configured as described above, the seat plate is further provided with battery diagnostic circuit means for diagnosing the capacity of the battery provided on the seat plate as a power source for starting the transmitter, and further, a fault. It is characterized in that diagnostic signal output circuit means for outputting a battery diagnostic signal in addition to the output of the detection signal due to the fact that the object detection switch is grounded on the floor surface is provided. According to the present invention, according to this structure, the battery check can be performed when the shutter curtain is fully closed. An embodiment of the present invention will be described next with reference to the drawings. FIG. 1 is a schematic circuit diagram showing an example of a safety device for carrying out the present invention. In FIG. 1, the safety device consists of a transmitter 1 side and a receiver 2 side, and
The power source pin Vdd of the transmitter IC 11 has a battery 12
, And key input means 13 is connected to the address pins, ..., And a digital signal is inputted from the key input means 13 to each address pin to control the number of bits corresponding to the number of address pins. Decide the code,
An arbitrary code signal is transmitted by infrared rays from the light emitting element 14 connected to the output pin. On the other hand, on the receiver 2 side, the light receiving element 22 is connected to the input pin of the receiving side IC 21 via the amplifier 23, and the amplifier 23
The control code is determined by correlating the received signal amplified by the key input means 24 with the digital signal input to the address pins, .... Of the address pins of the transmitting side IC 11 in the safety device, the first address pin is connected not to the key input means 13 but to the battery 12 via the battery diagnostic circuit 15, and the output from the diagnostic circuit 15 is output. The first
Set to input to the address pin. as a result,
Assuming that the number of address pins is n, of the n bit codes transmitted from the light emitting element 14, (n-
1) Use the bit for obstacle detection, which will be described later, and use the remaining 1
A bit "0" or "1" will be used to report the battery diagnostic status. On the receiver 2 side, only the bits corresponding to the address pins, ... Are made to correspond to the obstacle detection signal, and the bit corresponding to the first address pin is made to correspond to the display of the battery diagnosis state beforehand. After setting, for example, blink the LED 25, change the blinking cycle or color, and if there is a monitor screen display part, warn with a battery mark on the screen or a character display such as "please replace the battery" Or emit. FIG. 2 is a schematic circuit diagram showing another example of the transmission side circuit of the safety device for carrying out the present invention. In this circuit, in the transmitting side circuit, the key input means 13 for inputting to the transmitting side IC 11 is a key matrix by an XY address, and a battery diagnostic circuit 15 for detecting the state of the battery 12 which supplies a capacity to the power supply pin Vdd. The output from the above is input to the third address pin which is not used for the input from the key matrix. Then, transmitting a signal of a plurality of bits from the light emitting element 14 and using one of the bits for the battery information is the same as in the example of FIG. In these embodiments, the transmission / reception is carried out by transmitting / receiving infrared rays by the electro-optical element, but of course the invention is not limited to the above, and any digital signal transmitting means such as light, radio waves and ultrasonic waves can be used in the present invention. Both can be used. Next, an example in which the above-mentioned safety device is attached to an unmanned electric shutter for construction which is attached to a cash automatic payment corner of a bank will be described. In FIG. 3, reference numeral 31 is a shutter curtain 31 constituting an electric shutter for construction, and the shutter curtain 31 is opened and closed by the forward and reverse driving of a motor 32. This motor 32
It is located on the ceiling of the pillar 33, and is electrically connected to a remote operation unit (not shown) such as an office by a fixed wiring 34. The motor 32 itself is a target of wired remote control so as to be driven. The transmitter 1 is provided on a seat plate 31b provided at the lowermost end of the shutter curtain 31, and a seat plate switch 31 for detecting an obstacle is further provided on the bottom surface of the seat plate 31b.
a is provided. When the seat curtain switch 31a comes into contact with some obstacle 35 such as a person or luggage when the shutter curtain 31 descends, the obstacle detection signal is transmitted from the transmitter 1 to the receiver 2 provided on the ceiling. Based on this, after the descent of the shutter curtain 31 is urgently stopped, the shutter curtain 31 is raised or maintained in the urgent stop state as it is so as to prevent the obstacle from being caught by the shutter curtain 31. It is what In the embodiment of the present invention constructed as described above, when an obstacle is detected while the shutter curtain 31 is descending, the detection signal is transmitted from the transmitter 1 as described above. Based on the above, safety can be secured by, for example, stopping the shutter curtain 31 in an emergency. As described above, in the present invention, the shutter curtain 31 is urgently stopped on the basis of the obstacle detection to ensure the safety, but the power source for activating the transmitter 1 is as described above. Battery 1 mounted on the seat plate 31b
It is 2 and it is necessary to diagnose the capacity of the battery 12 as one of the confirmation items for confirming whether or not the obstacle can be reliably detected. However, in the present invention, when the shutter curtain 31 is fully closed in daily operation and the seat plate switch 31a reaches the floor surface, as shown in the block diagram of FIG. 4, the floor contact of the seat plate switch 31a is performed. The diagnostic signal of the battery capacity of the transmitter 1 is also transmitted by the operation of the transmitter 1.
The light emitting element 14 of the receiver 2 outputs and transmits the light to the light receiving element 22 of the receiver 2, and the receiving side IC 21 receives the limit signal and sends the limit signal to the shutter control circuit of the motor 32.
In addition to the normal drive stop, the signal indicating the battery diagnosis state is sent to the operation unit (not shown) by the wire line 34. If the input battery diagnostic signal means that the battery capacity is lower than a predetermined value, the warning light is blinked based on this, the blinking cycle is changed, or the lamp is turned on. A change in color or a buzzer is sounded to notify the decrease in battery capacity before the transmitter 1 is completely inoperative. Therefore, the operator can check the battery status of the transmitter of the safety device every time the operator remotely operates the shutter with the operation unit. As described above, the diagnostic condition of the battery capacity is checked by outputting and transmitting the diagnostic result every time the shutter curtain 31 is closed on a daily basis, and the condition can be immediately confirmed by the remote control unit. . This confirmation is always performed at the same timing when the shutter curtain 31 is fully closed. When confirming that the shutter curtain 31 has been safely closed, if the administrator further confirms that the capacity of the battery has decreased, immediately replace the battery with the new shutter curtain 31 that has been closed. As long as the battery abnormal signal is transmitted immediately based on the decrease in battery capacity, it is not necessary to wait for a long time for the battery replacement after the abnormal signal is received until the shutter curtain 31 routinely closes. It is possible to surely avoid switching the alarm device while waiting, and it is possible to reliably improve reliability. In summary, since the present invention is constructed as described above, the obstacle detection switch provided on the seat plate ensures the safety of the shutter curtain while detecting an obstacle. Although the descent control can be performed, the diagnostic result of the battery capacity for starting the transmitter provided on the seat plate is
The shutter curtain descends in daily operation, the seat plate comes into contact with the floor surface, and the obstacle detection switch is output at the same timing as the switch is operated. Based on this, the battery check can be performed. As a result, the check that the battery capacity has decreased is not performed at the time when the battery capacity has decreased to a predetermined state, but with the timing that the shutter curtain routinely descends. The administrator who confirmed that the battery capacity was reduced as the shutter curtain closed and the battery capacity was reduced, the administrator can immediately replace the battery with the newly closed shutter curtain. As with the one that outputs a battery abnormality signal at any time based on the decrease in battery capacity, the battery can be exchanged after receiving the abnormality signal by moving down the opened shutter curtains one by one to stop people from entering and exiting. You don't have to wait a long time for the shutter curtain to close on a daily basis, and Also possible to reliably avoid such things as turning off the switch of the alarm while it is possible to measure greatly increased reliability along with maintainability.
