Cis-position master-slave synchronisation control circuit device

The utility model relates to a cis position master slave synchronization control circuit device, which relates to the modularization continuous power supply system control circuit device in the electron control circuit field. The utility model comprises an audion, a light coupling pipe, a switch and a diode. The utility model adopts each module to produce one signal source, and all the signal sources are connected to the bus of the synchronous signal source through the electron switch. The signal source of the main module adjusted by the cis position master slave synchronization control circuit can close the electron switch, and communicate the synchronous signal and the synchronous bus to be used as the synchronous signal of the system. When the main module retreats the running due to failure, a new main module is produced from the running modules through the cis position master slave synchronization control circuit to produce new synchronous signal, the continuous synchronous signal is ensured, thereby ensuring the normal running of the system. The utility model has the advantages that: the cis position master slave synchronization control circuit device has high reliability, simple maintenance, convenient cubage enlarging and low cost. The utility model is used for being the control circuit device in the modularization continuous power supply system.
