Based On The Can Bus Triaxial Instrument Control System Developed

The rapid development of Computer Science and Digital Communication Technology leads to the revolution of Control Field. Distributed, Network and Intelligent System become the directions of Control Field. Field Control System (FCS) meets the demands of Control Technologies Developments. It becomes a new generation Control System after the Distributed Control System(DCS). And it becomes the mainstream of Control Field.According to the requirement of the triaxial instrument home market, the advantages and the disadvantages of control scheme in current triaxial instrument control system are analyzed in this dissertation. The development direction of the triaxial control system is studied. A set of triaxial instrument control system is researched and designed. The control system whose data communication mode is CAN bus has Real-time control characteristic. The designing of the hardware circuit, the programming of the software and the debugging of the control system are accomplished. The main research tasks are as follows:The corresponding communication protocols and the control mode of the triaxial control system are established.
