Research of Distributed Electrical Control System for Transpoting Girder Vehicle Based on CAN Bus

The beam carrier used for high-speed PC beams is a kind of SPMT-specific use,its electrical hydraulic control system is complex, the type and quantity of sensors and hydraulic actuators are numerous. The control system based on CAN bus distributed control system architecture, and designed into multiple control modules. The use of CAN bus as the system of information exchange between the various units of the channel, to the system design and wiring has brought great convenience. This paper expatiates on the hardware and software design, from the dynamic control, steering control, driving control, suspension and outrigger control, and gradually show the design process and control system structure of the control system. In the light of the advantages and disadvantages of the previous design of the beam vehicle, based on the use of the most advanced sensors on the beam vehicle for a full range of monitoring and precise control. This paper analyzes the heavy and difficult problems encountered in the development process and its solutions, which provides some reference for the design of the control module (SPMT). Successful development of the control system installed in the company''s HJY550 beam vehicle after debugging and commissioning, precise control, the functions are to meet the design requirements, the system is stable, safe and reliable.
