連続して繰り返して送１ｄシてＧ１ね。Remote control devices for coolers, heaters, etc. have fewer types of signals, and remote control devices (FFI) require fewer people, so there are periods when the transport route is unstable (often less than a few seconds). Also, the transmission signal (usually 1 unit of 10 milliseconds or more) is continuously and repeatedly sent for 1d and G1.

くなってしまう。In this case, the signal can be received accurately during a period when the transmission path is stable, so it is possible to achieve the nominal purpose. However,: 14t/Ii is limited (up to) 4 some power 3 It also becomes an IO unit, and systems that must require a response from remotely controlled equipment (for example, a system that requires a response from a centrally controlled In a system where remotely controlled equipment responds to the central government with information on how it is operating, it is difficult to keep the entire system working properly if the same signal is repeatedly sent from the central station. I become unable to do so.

Further, since the signal is transmitted only when the transmission path is stable, the reliability of signal transmission is improved. [Embodiments of the Invention] Hereinafter, the present invention will be described in detail with reference to the drawings.

る伝送路判断機能を有している。The microcomputer 1 is, for example, a TMP 8039P, and sends a transmission signal to the transmission circuit 2 and sends a transmission signal to the reception circuit 7.
It has a transmission path judgment function that reads the signal from and compares it with the transmitted signal.

2 to 3 KHz or higher), the output from the transmitter circuit becomes a signal (b) modulated with a high-frequency carrier wave (3301 (l (Z or higher)), which is transmitted from the transmitter circuit 2 to the indoor electric line 4 through the capacitor 3. Sent.

を完了することができなくなってしまう。Here, since various devices are connected to the indoor electric circuit, the impedance is not stable. It is extremely unstable because urine, noise, etc. are also being transmitted. However, as shown in FIG.
is not completely satisfied between the voltage waveform and the ninth period T, and as shown in Fig. 2, during the period t when the absolute value of the voltage is close,
In many cases, the noise 12 is not superimposed with zero. but,
This period t is several milliseconds, and unless both the 1st frequency and the carrier frequency are high, it will not be possible to complete all signals within milliseconds.

The reply from the remote control device 5 is transmitted to the microcomputer 1 via the indoor electric line 4, the capacitor 6, and the receiving circuit 7 to confirm whether the signal has been transmitted to the microcomputer 1.

隔制御装置５に信号が伝達される可能性が高くなる。To prevent this, if the signal can be sent when the indoor electrical circuit 4 is stable, the reliability of the signal will improve and the possibility that the signal will be accurately transmitted to other remote control devices 5 will increase.
このために、第１図において、スイッチ回路８を付加し

になる。When the switch 9 is closed according to the instruction from the switch circuit 8, the signal input to the receiving circuit 7 is caused by the resistor 10.
The signal level is high enough to be input to another remote control device 5, and reading the signal from the receiving circuit 7 equivalently obtains a reply from the remote control device 5. In this hypothetical case, if the test signal received from the receiving circuit 7 is legible and the same as the signal transmitted from the transmitting circuit 2, then
It can be seen that there is a good possibility that the signal is accurately received by the remote control device 5 as well. At this time, by opening the switch 9 and transmitting a control signal from the transmitting circuit 2, it becomes possible to transmit the signal to the remote control wholesale value VL5 with high reliability.
試験信号と制御信号の送信期間を合せて数ミリ秒以下に
する必要がある。The total transmission period of the test signal and control signal must be several milliseconds or less.
