Abstract

The invention relates to a sub-host system of an active radial control system. The sub-host system comprises a CPU processor, a communication module, an Ethernet interface and an oil cylinder controller. The CPU processor is connected and communicates with the communication module through a parallel port, and the communication module is in network communication with the oil cylinder controller, the upper computer and the train through Ethernet interfaces. The CPU receives the oil cylinder control information sent by the train network and the oil cylinder online state information sent by the oil cylinder controller, processes the information, generates system state information, uploads the system state information to the train network, and sends oil cylinder control data to the oil cylindercontroller. The system is the sub-host system used in cooperation with the active radial control system, the TRDP real-time Ethernet is adopted for train communication, and the requirement for real-time train control is met; the UDP mode is adopted for communication with the oil cylinder controller, unified sending and unified receiving are achieved, the control problem and the data delay problemcaused by one-to-one communication with multiple oil cylinders are avoided, and the control precision is improved.

Description

technical field [0001] The invention belongs to the technical field of active radial control systems, in particular to a sub-host system of the active radial control system. Background technique [0002] For a long time, when the train encounters a curve while running, it is completed by passive steering. The so-called passive steering is that the wheel rim rotates with the wheel rail through physical friction between the wheel rim and the wheel rail. The disadvantage of this method is that the long-term operation will wear the wheels and rails and increase the difficulty of maintenance. The active radial control system is to solve this problem by predicting ahead of the curve, preparing in advance and actively steering. This requires the cooperation of three aspects. First, the host computer collects the data of the curve ahead and calculates it. Second, it sends the calculation results to the oil cylinder controller of the vehicle through the network. Finally, the oil cy...
