本発明はりダンダント構成を持つ伝送装置における信号
系のバイパス方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a signal system bypass system in a transmission device having a dundant configuration.
従来のりダンダント構成を持つ伝送装置は、データ信号
を２系統の信号処理部に分配する信号分配回路を有する
パネルで構成されている。A conventional transmission device having a dundant configuration includes a panel having a signal distribution circuit that distributes a data signal to two signal processing sections.
上述した従来の伝送装置では、入力データ信号が分配不

送られないため両系統がダウンしてしまうという欠点が
ある。In the conventional transmission device described above, since the input data signal is an undistributable signal, the signal distribution circuit converts it into a distributable signal and distributes it to two signal processing sections. If separation occurs, there is a drawback that signals are not sent to the signal processing units of the two systems, causing both systems to go down.

特徴とする。The signal system bypass method according to the present invention uses a signal distribution circuit that distributes input data signals and generates an alarm signal when this signal distribution circuit is disconnected in a transmission device that has a redundant configuration of signal processing sections. The present invention is characterized in that it includes a panel missing detection circuit, and a switching circuit that switches signal paths in response to the alarm signal from the panel missing detection circuit.

２とを備えている。The transmission device of this embodiment has a redundant configuration having two systems of signal processing units A4 and B5, and input data signals from the data signal line 6 to signal processing units A4 and B5. A signal distribution circuit 1 that distributes to B5, a panel disconnection detection circuit 3 that detects when the signal distribution circuit 1 is detached, and a data signal from the signal distribution circuit 1 in response to an alarm signal from the panel disconnection detection circuit 3. A switching circuit 2 is provided which opens the line 7 and directly switches and connects the data signal line 6 to the signal processing section B5.

パスを形成する。If the signal distribution circuit 1 is detached, the panel detachment detection circuit 3 detects this and generates an alarm signal. Upon receiving this alarm signal, the switching circuit 2 switches the data signal line as shown by the broken line to form a bypass so that the input data signal from the data signal line 6 is directly input to the signal processing section B5.

Since signal processing can be continued by making use of the processing section, there is an effect of preventing two systems from going down.
