[0002]
[Prior art]
For the opening / closing body devices such as shutters and doors that are installed at the opening of a structure housing including buildings such as buildings, factories, and warehouses, electric shutters and electric doors that electrically open and close are often used. Many of the devices that perform the opening / closing operation electrically as described above include a wired operation switch (PBS) for controlling the operation. When this PBS is installed outdoors, it is often installed in a box with a key provided with a cylinder lock so that the PBS is not operated by a third party. However, the keyed box may be unlocked by picking, and the box itself or the upper lid may be pry open using a tool such as a hammer, a nail remover, or an electric drill. Further, even if the structure is strengthened so as to be able to withstand these, there are cases where it is not always a reasonable response method from the viewpoint of physical restrictions on the size and security performance and from the viewpoint of securing the aesthetics of the building. Therefore, for example, an open / close body control device configured to prevent the shutter curtain and the like from being easily opened even when the box with the key is pry open is proposed in Patent Document 1. . In this case, an electronic key for outputting a release signal is provided, and an opening / closing operation is performed based on the operation of an operation switch in accordance with the reception state of the release signal from the electric key.

[Problems to be solved by the invention]
The conventional one uses an electronic key that always outputs a release signal. Therefore, if the electronic key is left in the vicinity of the shutter curtain, it will always be in the released state, meaning the presence of the electronic key. May fade. In addition, it is convenient to improve the security point of view in a state where the release signal from the electronic key is not received (the operation switch is in an invalid state).
[0004]
Also, in the case where the release signal is received by wire or wirelessly, an undesired control signal is received intentionally or unintentionally, and the opening / closing body device is expected by the administrator. There was a risk of unexpected actions. For example, if an unspecified number of people pass, you may want to keep the opening open at certain times such as daytime, or in a factory or warehouse, etc. If you want to keep the opening open to pass through, it will be closed intentionally or unintentionally, that is, it will be closed accidentally, and it will be locked in the factory, room, warehouse, etc. There was a risk that it would end up. In addition, when the wind and light are actively entered by forming slits in the opening / closing body, or when the wind and light are not entered by releasing the slit, intentionally or the like There was a risk of unintentionally inadvertently moving in the opposite direction. Furthermore, when the opening / closing body is locked, there is a risk that the security measures will be insufficient due to inadvertent unlocking intentionally or unintentionally. Conversely, when unlocked, there is a risk that the device will be locked carelessly intentionally or unintentionally, resulting in insufficient measures to prevent confinement.
[0005]

The operation switch 18 has an open button, a stop button, and a close button, and outputs a control signal corresponding to the operation state of each button to the shutter drive circuit 16.
[0015]
The opening / closing body control device 17 is provided between the shutter drive circuit 16 and the operation switch 18, and includes a red lamp 29 indicating an alarm set state and a blue lamp 2A indicating an alarm release state. The state can be changed by a set / release remote control transmitter 19. FIG. 2 is a diagram showing a detailed configuration of the opening / closing body control device 17. The switching body control device 17 includes an antenna 20, a receiving circuit 21, a control circuit 22, a C contact switch 23, an EEPROM 24, switch means 25 to 28, a red lamp 29, a blue lamp 2A, an alarm buzzer 2B, and a relay switch 2C. . The control signal from the remote control transmitter 19 received by the antenna 20 is converted into a control signal by the receiving circuit 21 and transmitted to the control circuit 22. The control circuit 22 controls the C contact switch 23 and the switch means 29-2C based on the control data in the EEPROM 24. A red lamp 29 is connected to the switch means 25, a blue lamp 2A is connected to the switch means 26, an alarm buzzer 2B is connected to the switch means 27, and a relay switch 2C is connected to the switch means 28. In the EEPROM 24, one or a plurality of ID codes, which are unique numbers for specifying the remote control transmitter 19, can be stored. The stored IC code and the ID code of the remote control transmitter 19 are stored in the EEPROM 24. Only when they match, the control circuit 22 can output various control signals.
[0016]
When the signal from the remote control transmitter 19 is a signal related to the alarm set, the control circuit 22 turns on the switch means 25 to turn on the red lamp 29 and turns off the switch means 26 to turn off the blue lamp 2A. At the same time, the switch means 28 is turned on to operate the relay switch 2C, and the connection state of the C contact switch 23 is switched so that the open button 181 of the operation switch 18 and the control circuit 22 are connected. As a result, the open button 181 and the switch means 27 are connected to each other, and when the open button 181 is operated, the alarm buzzer 2B is activated and a loud buzzer sound is generated.
[0017]

As shown in FIG. 3A, the remote control transmitter 191 is a dedicated one having two buttons, an alarm set button and an alarm release button, and transmits a signal corresponding to the button. As another example, as shown in FIG. 3B, a remote control transmitter 192 that controls a normal opening / closing stop operation may be provided with two buttons, an alarm set button and an alarm release button. A signal transmitted from the remote control transmitter is taken into the control circuit 22 via the antenna 20 and the reception circuit 21 of FIG. 1, and the control circuit 22 performs processing according to the signal. In addition, the alarm set may be set when the stop button and the open button of the remote control transmitter for controlling the normal opening / closing stop operation are simultaneously operated, and the alarm may be canceled when the stop button and the close button are simultaneously operated.
[0021]
Next, an operation example of the opening / closing body control device of the present invention will be described with reference to the flowchart of FIG.
[Step S41]
It is determined whether the signal transmitted from the remote control transmitter 19 is an alarm set signal or an alarm cancel signal. If the signal is an alarm set signal (yes), the process proceeds to step S46. If the signal is an alarm cancel signal (no), the process proceeds to step S46. Proceed to S42.
[Step S42]
Since the signal transmitted from the remote control transmitter 19 is an alarm release signal, an OFF signal is output to the switch means 28, and the relay switch 2C is set to the OFF state. As a result, the C contact switch 23 connects the open button 181 and the shutter drive circuit 16.
[0022]
[Step S43]
An ON signal is output to the switch means 26 to light the blue lamp. At the same time, an off signal is output to the switch means 25 to turn off the red lamp.
[Step S44]
When the open button of the operation switch 18 is operated and it is determined whether or not there is an open input, the process proceeds to step S45 if yes (Yes), and returns to step S41 if not (no).
[Step S45]
Since it is determined that there is an open input in the previous step S44, the shutter opening operation is started in accordance with the operation of the operation switch 18 here.
[0023]
[Step S46]
Since the signal transmitted from the remote control transmitter 19 is an alarm set signal, an ON signal is output to the switch means 28, and the relay switch 2C is set to the ON state. As a result, the C contact switch 23 connects the open button 181 and the control circuit 22.
[Step S47]
An ON signal is output to the switch means 25 to light the red lamp. At the same time, an off signal is output to the switch means 26 to turn off the blue lamp.
[0024]
[Step S48]
When the open button of the operation switch 18 is operated, it is determined whether or not there is an open input. If yes (yes), the process proceeds to step S49, and if not (no), the process returns to step S41.
[Step S49]
Since it is determined that there is an open input in the previous step S48, here, an ON signal is output to the switch means 27 according to the operation of the operation switch 18, and the alarm buzzer is sounded. In this case, although the open button of the operation switch 18 is operated, only the alarm buzzer sounds in this case, and the shutter curtain does not move.
[0025]
In the above-described embodiment, the case where the connection is switched by using the relay switch and the C contact switch has been described. However, instead of using the C contact switch, the connection relation that has been switched by the C contact switch is appropriately switched by the microcomputer control. You may do it. In the above-described embodiment, the case where only the operation of the open button is disabled has been described, but it goes without saying that the operation of other stop buttons and close buttons may be disabled. In the above-described embodiment, the case where only the opening operation in the opening / closing operation such as the shutter curtain is made uncontrollable has been described. However, the opening operation, the closing operation, the stopping operation, the slit forming or releasing operation, Needless to say, the unlocking or locking operation can be similarly set to an uncontrollable state.
[0026]
In the above-described embodiment, the invalid or valid state can be visually confirmed using the lamp, but other displays may be used. For example, it may be recognized that the color seen from the opening is invalid when it is red, and valid when it is blue. Furthermore, in the above-described embodiment, the case where the alarm set and alarm release are set using the remote control transmitter has been described. However, when a card or the like on which electronic information is set is attached to the operation switch, an alarm is issued. An alarm may be set when the card is released and the card is removed. At this time, the operation may be executed only when the ID numbers recorded on the cards match. Moreover, you may enable it to perform an alarm set or cancellation | release by the combination of operation of the push button which comprises an operation switch.
[0027]
For alarm setting and cancellation, a wired signal line from a computer or the like may be used. In this case, it is desirable to protect the wire more firmly than the signal line of the operation switch for crime prevention and mischief measures. For example, it is conceivable to protect by a measure such as wiring inside a metal pipe or the like that is not touchable or difficult to touch such as a ceiling.
