し送信する信号伝送方式に関するものである。DETAILED DESCRIPTION OF THE INVENTION In one-way communication in which signals are transmitted from one transmitting station to a plurality of receiving stations, the same signal is This relates to a signal transmission method for return transmission.
従来の方式では伝送路が片方向であるため送信局は送っ
た信号が正しく受信局に伝わったがどうか確認すること

では、全ての信号について同一回数くシ返して送信する
ため、くシ返し回数をＮとすれば伝送路の利用効率はＮ
に烙ちる欠点があった。In the conventional system, the transmission path is unidirectional, so the transmitting station cannot confirm whether the transmitted signal has been correctly transmitted to the receiving station, and some stations may not be able to receive the signal correctly. Occur. Therefore, by transmitting the same signal multiple times in succession, ignoring the erroneous signals at the receiving station, and inputting only the correctly received signals, and considering the consecutive same signals as one signal, This prevents signals from being missed due to errors occurring on the transmission path. However, in this method, all signals are repeated and transmitted the same number of times, so if the number of repetitions is N, the utilization efficiency of the transmission path is N.
There were some notable drawbacks.

率は落ちる。The present invention provides a signal transmission system that solves the above-mentioned drawbacks by increasing the number of repetitions for signals with high M requirements and decreasing the number of repetitions for signals with low importance, thereby increasing the efficiency of use of the transmission path. First, the conventional method will be explained using Figure 1. The signal l to be transmitted is once stored in the memory circuit 2. The repeat transmission circuit 3 attaches a check code to the signal stored in the storage circuit 2 and outputs it to the transmission line 4 a fixed number of times. A large number of receiving stations 5.5', 5'... check the received signals through a checking code and ignore any errors.
Only the correctly received signal is compared with the previously received signal, and if the signal is different, the received signal 6.6', 6'
・・・・・・Full output. In the above method, the transmission line 4
Since the same number 16 is always transmitted a certain number of times, the usage efficiency decreases.

路４に送信する。The signal 1 to be transmitted is once stored in the memory circuit 2. The importance determination circuit 7 notifies the repeat transmission frequency signal 8 to the repeat transmission circuit 3 according to the importance of the signals stored in the circuit 2. The circuit 3 attaches a test signal to the signal from the circuit 2 and transmits it to the transmission line 4 by repeating it the number of times indicated by the signal 8.
