次に、この回路の動作を第２図を用いて説明する。Next, the operation of this circuit will be explained using FIG.

発生し、これを第３図Ｃに示すパルス列に重畳して信号
回線５へ送信するため実際の送受信波形は第２図ｄに示
すようになる。The control signals a-1 and a-'l for selecting the signal input device 2-1 and the signal output device 2-2, respectively, alternate according to a predetermined program, and the signals shown in FIG. The transmission control device 1 generates such a synchronizing pulse, superimposes it on the pulse train shown in FIG. 3C, and transmits it to the signal line 5, so the actual transmission and reception waveforms become as shown in FIG. 2d.
この送受信波形に含まれる同期パルスの間隔がサイクリ

なる。Now, as is clear from the above explanation, in the conventional multiplex transmission device shown in Fig. 1, it is necessary to set the length of the transmission cycle in advance according to the number of signals transmitted and received in one transmission cycle, that is, the number of signal input/output devices. Moreover, it is necessary to set the direction of transmission (transmission, reception) in advance according to the type or distribution of input and output, which is very cumbersome.

を行なうならば、徒に伝送周期を長くして伝送効率を下
げるのは自明である。However, if we take elementary measures such as fixing the transmission cycle to match the maximum number of signal input/output devices in order to avoid this initial setting, it is obvious that we will unnecessarily lengthen the transmission cycle and reduce transmission efficiency. be.
この発明はこのような点に鑑みてなされたものであって
