Abstract

The embodiment of the application provides a bus valve control system, and belongs to the technical field of engineering equipment. The system comprises a controller, which is used for sending a bus starting command to a bus valve when a system power-on signal is received; the bus valve is used for sending working state information to the controller based on a preset sending period when the bus starting command is received. An input mechanism is used for sending demand information to the controller; the controller is further used for determining a first control instruction based on the demand information and sending the first control instruction to the bus valve based on a preset sending period; and the bus valve is used for outputting a second control instruction based on the first control instruction. By using the bus valve, the number of control wiring harnesses is greatly reduced, the system is simple and beautiful, space and wiring harness cost are saved, wiring harness connection errors are effectively avoided, and control effectiveness is improved.
