Description

[Detailed description of the invention] [Field of industrial application] This invention automatically controls the opening and closing of a shutter curtain, such as an architectural shutter installed in an opening, by wireless control commands from a transmitter. The present invention relates to an opening/closing control device for an opening.

[Problems to be solved by the prior art and the invention] Generally, in the case of an opening/closing means provided in an opening such as this type of architectural shutter, a receiver receives control commands by radio from a transmitter. Therefore, there are devices that allow opening and closing control, but in the past, the input signal from the transmitter was one type from a single push button switch.
On the receiver side, when a signal from the transmitter was input, the relay circuit was set to switch in the order of stop → open → close, thereby controlling the opening and closing of the opening. For this reason, when using wireless opening/closing control, even if you want to stop it urgently, it can no longer be stopped by commands from the transmitter, which is extremely dangerous and less safe. There were flaws. Therefore, we installed three types of push button switches on the transmitter: open, close, and stop.
Some of these push button switches allow the receiver to receive desired commands to control the opening, closing, and stopping of each switch individually.
In this case, in an emergency, it is often dangerous to press the push button switch on the transmitter side by mistake, and it is also necessary to secure three types of lines at all times, so the number of radio wave codes is limited. The number of control switches is reduced to 1/3 compared to the single push button switch mentioned above, and as a result, unrelated neighboring switches may be activated by commands from the transmitter. In order to avoid any inconvenience, the information transmitted from the transmitter side can be arbitrarily set and the number of radio wave codes that function as keys is reduced, which has become a problem.

[Means for solving the problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing an opening/closing control device for an opening that can eliminate these drawbacks. In order to control the opening and closing of the opening by driving the drive unit in response to a command from the transmitter at the receiver, the receiver is provided with a sensing means for sensing whether or not the drive unit is being driven; and the sensing means. The device is characterized in that it is configured by providing a discrimination circuit that inputs a command from the drive unit and determines whether to issue a stop command if the drive unit is driving or to issue a drive command if the drive unit is stopped. It is.

With this configuration, the present invention allows the receiver to issue two different control commands to control the opening, closing, and stopping of the opening, even though the receiver receives a single control signal. This not only eliminates the possibility of pressing the button by mistake in an emergency, allowing the drive to be stopped quickly and safely, but also ensures that it functions effectively as a key without reducing the number of radio wave codes. It has been made possible.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawings, reference numeral 1 denotes a shutter curtain for an architectural shutter that opens and closes an opening, and the shutter curtain 1 has a control circuit mechanism 2 which will be described later.
The opening can be opened and closed by forward and reverse rotation of a drive motor M (drive section) driven by a command from the opening. 3 is a guide rail, 4
is a shutter case.

A circuit diagram of the control circuit mechanism 2 is shown in FIG. 2, where LSU is an upper limit switch,
The LSD is a lower limit switch, and these are normally closed, but the shutter curtain 1
When it reaches the upper limit position or the lower limit position, it is opened to open the circuit and stop driving the drive motor M. Also, MCU is a relay switch for raising, and MCD is a relay switch for lowering.
By closing the open switch US and the close switch DS formed by push button switches, the open side circuit (circuit passing through terminals B3, B2, L1),
Alternatively, the closed side circuits (circuits passing through terminals B3, B4, and L2) are each self-maintained to drive the drive motor M forward or backward to the release side or the close side. ST is a stop switch. Furthermore, the control circuit mechanism 2 includes a switch contact RU of a rising timer relay switch TU, which is switched by a command from the transmitter side, which will be described later, and a lowering timer relay switch TD.
Each switch terminal is provided at the switch contact RD of the stop timer relay switch TS and the switch contact RS of the stop timer relay switch TS.

On the other hand, FIG. 3 shows the circuit mechanism on the receiver side, which includes sensing means consisting of a photocoupler TP and two sets of sensing means for sensing whether or not the drive motor M is being driven. AND circuit a, b
Discrimination circuits 5 are each provided with a discriminator circuit 5 consisting of a signal received from a transmitter and a photocoupler.
The sensing signal from the TP is input to the photocoupler TP, but the photocoupler TP is not electrically connected when the drive motor M is being driven, that is, when the power supply circuit to the drive motor M is closed. In this case, the circuit to the discrimination circuit 5 is grounded to set the input signal to the discrimination circuit 5 to 0, and when the drive motor M is stopped, the photocoupler is
TP is not sensitive, and in this case, the input signal to the discrimination circuit 5 is set to 1. In this way, in the discrimination circuit 5, when a command from a transmitter (not shown) is input while a sensing command from the photocoupler TP is being input, if the drive motor M is stopped, , the discrimination circuit 5 receives an input signal of 1. Therefore, in this case, in the discrimination circuit 5, a switching command is issued from the AND circuit a to the rising timer relay switch TU, and the shutter curtain 1 is set to the highest level. When the shutter curtain 1 is not in the raised position, the drive motor M is driven and the shutter curtain 1 is raised. seconds), a switching command is issued to the lowering timer relay switch TD, so that the shutter curtain 1 is lowered. On the other hand, when the drive motor M is driving, 0 and 1 signals are input to the discrimination circuit by receiving the signal from the transmitter, so in this case, the stop signal is input from the AND circuit b. A control signal is sent to the timer relay switch TS, the switch terminal RS is opened, and the driving of the drive motor M is stopped.

In the embodiment of the present invention constructed as described above, the shutter curtain 1 has manual switches US,
Although it can be opened, closed, and stopped as before by operating DS and ST,
Opening/closing and stopping control can also be performed by remote control using a transmitter. First, when you want to raise the closed shutter curtain 1 to open it, operate the push button switch on the transmitter to send a control signal to the receiver. The motor M is driven to raise the shutter curtain 1. That is, when the shutter curtain 1 is in the closed position, the drive motor M is stopped, so the photocoupler TP does not respond, and therefore the input signal from the photocoupler TP to the discrimination circuit is 1.
It is becoming. Therefore, in the discrimination circuit 5 that receives the input from the transmitter, an output is output from the AND circuit a side, and as mentioned above, the up timer relay switch TU is activated, the switch contact RU is closed, and the drive motor M is activated to operate the shutter curtain. 1 will be driven to increase. On the other hand, when the shutter curtain 1 is in the open state, in the receiver that receives the control signal by operating the transmitter, the discrimination circuit 5 outputs the control signal from the AND circuit a side and lowers the control signal after the timer time elapses, as in the case described above. The timer relay switch TD is activated and the switch contact RD is closed.
The drive motor M drives the shutter curtain 1 to lower it. When the drive motor M is driven in this way, especially when the shutter curtain 1 is lowered, if a person tries to pass under the lowered shutter curtain 1 or an obstacle is hit and an emergency stop is desired, the main When it comes to ideas,
As described above, the shutter curtain 1 can be stopped by operating the same push button switch used to raise and lower the shutter curtain 1 on the transmitter. That is, when the drive motor M is driving, a 0 signal is input from the photocoupler TP to the discrimination circuit 5, so the discrimination circuit 5 that receives the received signal from the transmitter receives the control command from the AND circuit b. is output to stop the timer relay switch
TS is activated, the switch terminal RS is opened, and the drive motor M is stopped.

As described above, in the present invention, on the receiver side that receives the signal from the transmitter, the discrimination circuit 5 has a sensing means for sensing whether or not the drive motor M is being driven; sensing signal,
Two types are distinguished depending on whether the drive motor M is stopped or when it is being driven. When the drive motor M is stopped, the drive motor M is driven to perform opening/closing control, and when the drive motor M is Discrimination control can be performed to perform stop control if the vehicle is being driven.
Moreover, this discrimination control is not performed by inputting separate dedicated signals from the transmitter as in the past.
Since this is done in response to a signal from the operation of a single pushbutton switch, there is no possibility of pressing the pushbutton switch by mistake on the transmitter side during an emergency stop, resulting in extremely high safety. Moreover, since only one channel of the radio line is required for opening/closing and stopping control, the number of radio wave codes will not be reduced, and the remaining codes can be used as keys for any information transmission means. Therefore, it is possible to set a large number of code keys, and it is possible to effectively prevent inconveniences such as opening and closing nearby shutter curtains due to the operation of the transmitter.

Furthermore, in this embodiment, when the drive motor M is driven by the operation of the transmitter, priority is given to raising the shutter curtain 1, so that safety is further improved.

It goes without saying that the present invention is not limited to the above-mentioned embodiments, but its scope of use is not limited to architectural shutters, but can also be applied to doors, etc. as long as it is a wireless means of opening and closing openings. can be provided. Furthermore, there is no need to limit the detection of whether or not the drive unit is driven to the photocoupler;
As long as this can be detected, the means used does not matter. Also, if the drive unit is running,
It is also free to set it to stop only when the door is closed, not when it is open. Furthermore, in the discrimination circuit, the command from the sensing means is
Any system that can determine whether the drive section is driving or not and issue commands accordingly will suffice.

[Operations and Effects] In short, the present invention is constructed as described above, and although it is designed to perform opening/closing control by inputting a single signal from the transmitter side, it does not require any input from the sensing means. The discrimination circuit that received the command,
Discrimination control is performed to determine whether or not the drive unit is being driven, and to issue a stop command when the drive unit is in operation for opening/closing control, and to issue a drive command when the drive unit is stopped. An emergency stop can be reliably performed by a command from a transmitter. Moreover, this emergency stop does not require operating a dedicated stop switch on the transmitter side, but can be performed by operating the same switch that issues the open/close command, so it is extremely safe and there is no chance of pressing the switch by mistake. can be taken as a thing. Furthermore, the receiver distinguishes a single type of command from the transmitter according to the driving status of the drive unit, so even though it can control opening, closing, and stopping, it only uses one wireless channel. Therefore, it is possible to effectively secure the number of radio wave codes required to function as keys, and it is possible to effectively prevent the occurrence of inconveniences such as neighboring devices operating at the same time.
