Excessive load on the train communication network can lead to delayed or lost data transmission, which in turn affects the efficiency and accuracy of the feedback control system. To ensure the security of the train communication network, a CANopen based train communication network state feedback control system is designed. Install CANopen gateway equipment, modify train communication network data collector and network state feedback controller, adjust the connection method of feedback controller driver circuit, and complete hardware system optimization. Set CANopen as the communication protocol for the train communication network, collect real-time status data of the train communication network through message capture, and determine the current train communication network status through the extraction and matching of network status features. Calculate the control amount of the train communication network from the aspects of cache length, load, delay, etc., and achieve the train communication network state feedback control function of the system through two steps: fair allocation of train communication network channels and congestion scheduling control of the train communication network. The experimental results show that in the communication network environment of railway trains and highway trains, the average load control errors are 0.6Mbps and 0.8Mbps, respectively. Under the control of the proposed method, the average cache queue length of the communication network is 10Mbps, which proves that the optimization design method has significant advantages in control function and control effect.
