Industrial Manifold Control Systems UsingHigh Speed Networks

[摘要] In this paper, a multi-motor control circuit based on controller area network (CAN) bus is presented. The PIC (16f877A) microcontroller is the foundation and the circuit which is based on the usage of inbuilt digital-to-Analog converter, in order to achieve the breakdown of motor control. In the subdivision control, subdivision steps are set by software. Article details the overall structure of the system of hardware design, software design process, and CAN bus controller structure. Compared with the traditional centralized control, the multi-motor control system has higher reliability. Experimental result shows that the system and the intelligent control module is effective and efficient..
