Rail weighbridge management and control system

The invention discloses a rail weighbridge management and control system. The system comprises a rail weighbridge body assembly, a data channel host and a local controller which are electrically connected in sequence, and an auxiliary assembly electrically connected with the local controller; the auxiliary assembly is used for determining whether a to-be-detected vehicle is located on the rail weighbridge body assembly (auxiliary); the rail weighbridge body assembly is used for collecting the weight of a to-be-measured vehicle, generating an initial weight signal according to the weight, and sending the initial weight signal to the data channel host; the data channel host is used for performing data conversion on the initial weight signal to obtain a target weight signal and sending the target weight signal to the local controller; and the local controller is used for judging whether the target weight signal is abnormal or not. Whether the target weight signal is abnormal or not is determined in real time, an
