のである。DETAILED DESCRIPTION OF THE INVENTION When remotely controlling equipment with a large number of control functions, such as solar heat or gas combustion water heaters or air conditioners, the present invention reduces the number of cores of the connection cable between the equipment body and the controller to two. This relates to a two-wire remote control system.

ように本体と操作器を離しておき、遠隔装作を行
なうことが多い。 Water heaters that use gas or oil combustion, or bathtubs with hot water, are installed outdoors for safety reasons. Therefore,
In places where hot water is actually used, such as the kitchen or bathtub,
Combustion control of the main unit and control status monitoring are performed remotely using a hand-held controller. Furthermore, for devices with a large number of functions, such as room air conditioners, the main body and operating device are often separated from each other, and the equipment can be remotely installed, like the water heater mentioned above.

信号到達範囲の限定が問題であり、２線方式が有
利と考えられている。 Traditionally, cables with 10 or 20 cores depending on the number of functions have been used to connect the controller to the main unit, but since this connection is made at a location such as a home, the number of cores is large. The problem is that the construction work is difficult and accidents such as connection errors or poor connections are likely to occur. Furthermore, there is also the problem that an increase in the number of functions cannot be expected due to the limitation on the number of cable cores. Therefore, there is a need for a wire-saving or wireless remote control device that multiplexes and transmits control signals and display signals between the main body and the handheld controller. Wireless systems have problems with noise and limited signal reach, and two-wire systems are considered advantageous.

Ｎ比と伝送電力の容量が問題である。 Two-wire remote control devices do not have a separate power transmission line as in the past, so it is necessary to input a commercial 100V power source to the main unit and controller side, but the power supply circuit is duplicated. It is triple layered and expensive. In addition, there is a method in which the commercial power input is input to either the main unit or the controller by superimposing DC power and signals on the signal transmission path.
The problem is the N ratio and the transmission power capacity.

る。 In the present invention, the signal SW ratio is increased by temporally separating and transmitting the power transmission signal for the DC power supply and the digital control signal for creating the power source for the IC on the controller side, the light emitting element, the buzzer, etc. At the same time, sufficient DC power is transmitted from the main unit side where commercial power is input to the controller.
The present invention provides a wire-type remote control device. In addition, by setting the voltage of the power transmission signal higher than the control signal voltage, the S/N ratio of the transmitted signal can be kept high, and even if voltage ripples occur on the side receiving the transmitted power, stable IC etc. This makes it possible to provide driving voltage. Furthermore, by using the falling portion at the end of the power transmission signal as a reset signal, it is possible to ensure signal transmission and reception between the main body of the control signal and the operating device.

ンサ１５の容量値を設定する必要がある。 At time t1 , the base drive of the transistor 4 is stopped by the signal control circuit 10, and the transistor 4 is turned off and the transistor 3 is turned off. During the period t 1 to t 2 when the transistor 3 is off, the peak voltage is at the voltage level b (second
In Figure A), it is determined to be lower than just before t 1 . Then, the transistor 6 is turned on and off by a signal from the signal control circuit 10 that is generated according to the combustion control state, and a digital signal of a combination of "1" and "0" is generated. The control signal generated between times t 1 and t 2 is transmitted to the operating device through the lines 12 and 13, and a signal that takes into account the instruction setting of the control circuit block 19 is generated between the lines 12 and 13. The operation instruction setting signal of the main body by the control circuit block 19 short-circuits or opens the lines 12 and 13 within the block 19 during a time interval (corresponding to 1 bit) allocated to the period from time t 1 to t 2 . It is generated by As a result from t 1 to t 2 , the line 12,
The signal generated at 13 is generated as, for example, "01011011" as shown in FIG. 2A. Next, to drive the LEDs, buzzers, etc. included in block 19 of controller B that displays the operating status of the main unit, the signals during the period t 1 to t 2 are decoded within circuit block 19 in the controller.
In response to the signal, a switch installed in series with the display element is turned on and off to perform a display operation. The driving power source for the display element is not particularly required to have constant voltage characteristics, and is directly connected to the capacitor 15 at the point Y. Between time t 1 and t 2 , the voltage of the driving DC power supply decreases as shown in C in Figure 2 (b), so that at time t 2 at C
It is necessary to set the capacitance value of the capacitor 15 so that the value of d is kept higher than the constant voltage value d for the driving power source of the IC, etc. of the control circuit block 19.

および条件設定を行なう。 At time Tt 2 when the transmission of the control signal is completed, the transistor 4 is turned on and the transistor 3 is also turned on according to an instruction from the control circuit 10 in the main body A. Therefore, the voltage between lines 12 and 13 increases,
As the voltage of the capacitor 15 increases, the voltage increases to the level at which the capacitor 2 is charged. and time t 3
When the transistor 4 is turned off again, the transistor 3 is turned off. During the period from t4 to t3 , the transistor 6 is turned on and off, and the instruction setting switch of the operator B is turned on and off to generate a control signal. Then repeat the above steps for the required length. Among the signals during the periods t 1 - t 2 , t 3 - t 4 ,...
The instruction setting signal from the operator B is taken into the signal control circuit 10 through the connection point Z, sampled and held, and is used to instruct and set conditions for the operation of the main body combustion control circuit 11.

In order to do this, signal generation and sampling operations must be performed accurately in synchronization on the main body A side and the controller B side. Therefore, at times t 1 , t 3 ,...
The circuit is reset by detecting a voltage fall at the terminal, and the timers on the main body and the controller are started. By doing so, it is possible to match the signal recognition between the A side and the B side. this
The rise time at t 1 , t 3 , . . . is delayed due to the influence of distributed capacitance, etc., and the reset timings A and B may not match. In that case, by setting the reset timing to the time when the transistor 6, which has been kept off for one to several bits after the rising edge at t 1 , t 3 . . . It is possible to precisely match the reset timing with the

Similarly, it is also possible to set instructions for combustion control operations on the operating device or to display the control status using LEDs or the like by interpreting control signals using a known technique using a microprocessor.

る。 Note that the transmission and reception of signals as shown in Figure 2A does not need to be repeated throughout the entire time that the main unit is in the operating state; for example, a certain state can be set by repeating transmission two or three times or by confirming the signal by answering. If so, the transmission of the control signal is stopped until the next state change, and the transmission of the control signal is stopped until the next state change.
is always on and the capacitor 15 is charged.
It can be similarly applied to cases where the DC power supply voltage is maintained at a sufficient value. In other words, it is necessary to prevent the voltage C from falling below level d between t 1 and t 2 or t 3 and t 4 in FIG. 2 when the control signal is being transmitted and received. It is necessary to maintain a sufficient length of section for power transmission between each set.
