Develop Of Computer Control System Of New 160t Type Railway Crane

Based on study and research on various safety monitoring systems of domestic and foreign railway cranes, a new generation of computer controlling system for railway crane is developed with full utilization of modern electronic computer and sensors. The system is incorporating not only normal functions like measuring, controlling and warning for out of limits, but also high resolution color Chinese display and black box used to record historic data. It demonstrates high intelligence.In addition to improved functions, advanced level and higher reliability of the system, field bus technology (CAN bus) is adopted so that the customer can dynamically add and delete nodes (CAN monitoring modules) according to different railway cranes with no modifications on hardware. The system is consisted in one host node (CPU), one force limiter controlling node, one upper rotation platform slave node, two bottom rotation platform slave nodes, two supporting structure intelligent slave nodes and ten minimum system nodes. The minimum system nodes serve to collect signals, convert from A to D and transmit data to hose node by CAN bus. The hose node computes and processes the collected data and then transmits the results to LCD and drives various controlling actions.The paper mainly expounds the general plan of hose node and slave node of the system, design concept of software and hardware and referred knowledge. Some critical components have been analyzed in detail.
