Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multiple transmission remote control system.

FIG. 1 is a schematic diagram of a multiplex transmission remote control system, in which a main operation panel 1 has a built-in stabilized power supply, signal generation circuit, etc., and connects multiple control terminals 3 through two dedicated wires 2. Monitor and control. It also monitors and controls the monitoring input terminals 4. Addresses are individually given to each terminal device 3... and monitoring input terminal device 4..., and the main operation panel 1 sends a control signal to each address and also receives return signals from the monitoring input terminal device 4... Process. Each control terminal 3... has a pair of signal input terminals connected to the dedicated two wires 2, and
A controlled load (for example, a lighting device) 6 is attached, and a signal detection circuit, a relay drive circuit for driving a remote control relay, etc. are provided inside. On the other hand, like the control terminal 3, the monitoring input terminal 4 has a built-in logic circuit section including a signal detection circuit, a reply circuit, etc., and can be connected to the control terminal 3 by turning on an externally operable push button switch. A return signal for generating a control signal for controlling the controlled load 6 is transmitted to the main operation panel 1 at a predetermined timing.

As shown in FIG. 2, the main operation panel 1 sends a start signal, address signals for the control terminals 3 and monitoring input terminals 4, control signals, and return (monitoring) waiting signals. A set of signals is transmitted sequentially and cyclically for each address in a time-division manner. The start signal indicates the start point of the data transmission period for each of the control terminals 3... and the monitoring input terminals 4, and the address signal is a pulse width modulated pulse, and the address signal is a pulse width modulated pulse. Input terminal device 4
It is responsible for address data for individually calling... The control signal is also formed by pulse width modulation, and in each called control terminal 3, the corresponding controlled load 6
...or, in the called monitoring input terminal 4..., it is responsible for control data for driving and controlling the operation display units, respectively, and also, during the return waiting signal period, the main data is transmitted from the called monitoring input terminal 4... Return signals of data regarding the operation operations of the monitoring input terminals 4 . . . are transmitted to the operation panel 1 . Next, the relationship between the monitoring input terminals 4 and the control terminals 3 will be explained. Now, in FIG. 1, for example, the address of the control terminal 3 is set to "address 1", and the monitoring input terminal 4 transmits a control signal based on the operation content from the main operation panel 1 to the corresponding terminal by its operation operation. Assume that the address to be transmitted to the device is set to, for example, "address 1". Next, it is assumed that the push button switch for reply input of the monitoring input terminal 4 is turned on and its operating state is memorized by the built-in logic circuit, and when it is called by the address signal from the main operation panel 1, The monitoring input terminal 4 transmits a signal with a predetermined code as a return signal to the main operation panel 1 during the return waiting signal period. The main operation panel 1 stores this return signal and also stores the address of the monitoring input terminal 4. The addresses of the monitoring input terminal 4 at a predetermined address and the corresponding control terminal 3 are programmed in advance on the main operation panel 1, and when a signal is transmitted to "address 1" corresponding to the address of the monitoring input terminal 4, In this case, the main operation panel 1 sends a predetermined code signal as a control signal. The control terminal device 3 that receives the control signal operates a relay drive circuit to turn on the controlled load 6 using a built-in logic circuit, thereby turning on the remote control relay. In this way, the monitoring input terminals 4 are sequentially called.
The return signal from the monitor input terminal 4 of the corresponding address is read and stored by the main operation panel 1, and the main operation panel 1 transmits the control signal created based on the return signal from the monitoring input terminal 4 of the corresponding address to the corresponding control terminal 3. That's what I do.

However, the conventional monitoring input terminal 4 requires wired remote control from a location away from where it is installed, which is inconvenient.

The present invention was made in view of the above problems.
The purpose is to provide a multiplex transmission remote control system equipped with an easy-to-operate monitoring input terminal that can be operated wirelessly or with a conventional push button switch.

The present invention will be explained below with reference to Examples. FIG. 3 shows an exploded perspective view of the monitoring input terminal 4 used in one embodiment of the present invention, and FIG. The first printed circuit board 8, which has been wired and attached, is fixed with tapping screws 9. 10 is body 7
This cover 10 is a cover that is attached to the body 7.
The second printed circuit board 16 connected to the printed circuit board 8 via the lead wire 11 is fixedly housed inside with a tapping screw 9', and the receiving section 12 is similarly secured with a tapping screw 9''. The receiving section 12 is fixedly stored on the light receiving surface 1.
2a is exposed through a filter 14 to a window hole 13 opened on the top surface of the cover 10, and is capable of receiving optical signals transmitted from outside the main body A. 15 is a switch handle of a push button switch 17 mounted on a printed circuit board 16;
The switch handle 15 is resiliently sprung by a coil spring 19 that is compressed between the upper surface of the printed circuit board 16 and the lower surface of the switch handle 15 so that the head of the switch handle 15 protrudes outside through a window hole 18 formed in the cover 10. When pressed, the protrusion 2 into which the coil spring 19 is inserted
0 through the hole 20 of the printed circuit board 16, for example, closes the contact point on the upper surface of the printed circuit board 8 to turn on the switch. Of course switch handle 1
The contact may be closed at 5. Numeral 22 is a bolt for connecting and fixing the body 7 and cover 10, and 23 is a mounting frame for attaching the main body A to an embedded hole or the like.

FIG. 4 shows a circuit block diagram of the monitoring input terminal 4. In the figure, 24 is a transmitter, and this transmitter 24 is designed to transmit a wireless signal consisting of an optical signal. When the switch is turned on, a signal is emitted in an appropriate signal format. On the other hand, the monitoring input terminal 4 includes the receiving section 12 that receives and receives optical signals as described above, the amplifying section 25 that amplifies the received signal of the receiving section 12, and the amplifying output of the amplifying section 25. A detection unit 26 that detects and extracts a predetermined signal, a signal processing unit 28 that sends a desired signal to a logic circuit unit 27 consisting of a microcomputer etc. using the output of the detection unit 26, and a push button switch 17 that outputs the output of the signal processing unit 28. It is equipped with an OR gate 29 that performs a logical sum with the input signal of the address signal, and the logic circuit section 27 that performs processing for transmitting a return signal and receiving an address signal control signal. Note that the system outside the monitoring input terminal 4 has the same operation and configuration as the conventional system explained in FIG. 1, so the configuration and operation thereof will be omitted.

Therefore, when the transmitter 24 is not transmitting and the detection section 26 has no output, the transistor Q ₁ of the signal processing section 28 is in the OFF state and the transistor Q ₂ is in the ON state. Therefore, when the push button switch 17 is open, the OR gate 29 does not output an "H" signal, and as a result, the logic circuit section 27 does not receive a signal at the input terminal I, so the return signal cannot be sent at a predetermined timing. Don't do it.

Next, when an optical signal is sent from the transmitter 24, the light receiving surface 12 of the receiving section 12 of the monitoring input terminal 4
A signal is received and received at a, and the received signal is amplified and detected to turn on the transistor _Q1 . When the transistor Q ₁ is turned on, the transistor Q ₂ is turned off and the input signal is inputted to the input terminal I of the logic circuit section 27 through the OR gate 29 .
When the logic circuit unit 27 is called from the main operation panel 1 by inputting a signal to the input terminal, it returns a return signal for generating a control signal for the corresponding control terminal 3 via the dedicated two wires 2. I will do it.

Also, when the push button switch 17 is turned on, the OR gate 29 outputs an "H" signal, so when the push button switch 17 is turned on, the same logic as when receiving the radio signal from the transmitter 24 is applied. Circuit section 2
7 will work.

In the present invention, as described above, since the monitoring input terminal is provided with a receiving section that creates a return signal for generating a control signal corresponding to the controlled load of the corresponding control terminal, the wireless signal is transmitted from the transmitter. By sending out the , the control terminal can be remotely operated even from a location far from the monitoring input terminal, and since it is not wired, remote control can be performed almost arbitrarily from a wide range of locations. is provided on the monitoring input terminal, so it can be used in the same way as before.Furthermore, since the receiving section is provided on the front of the main unit, it is easy to receive wireless signals such as optical signals, and wireless transmission is possible. This has the effect of making it easier to operate, and since the push button switch is also provided on the front, it is easier to operate the push button switch.
