Problems solved by technology

[0003] Since the circuit control system contains multiple sub-circuit modules, each sub-circuit module realizes a specific circuit function, and each sub-circuit module is in a corresponding operating state under integrated control, the circuit control system has high maneuverability and flexibility ; However, in the process of integrated control of multiple sub-circuit modules, users need to obtain the operating status or fault status of each sub-circuit module in real time to ensure the safety performance of the circuit control system; however, in order to obtain the operation of each sub-circuit module state, each sub-circuit module needs to transmit power separately to obtain the operating performance of the circuit module, which will not only generate a large power loss, increase the cost of the state display of the circuit control system, but also lead to wiring between multiple sub-circuit modules The structure is more complex, which brings great inconvenience to the circuit control process of multiple sub-circuit modules, and reduces the safety and reliability of the circuit control system
