ABSTRACT
Recently, the industrial bus technology is a research hotspot in industrial control area. The industrial bus technology has many advantages, it is more extensively compare to the traditional web control, can be supported by all the programming language, abundant software and hardware resources, easy to be connected with internet, it also can achieve the seamless connection of office automation web and industrial control web and so on.
The title of this graduation project is based on the SJA1000’s CAN bus controller, this system is formed by three parts: microcontroller AT89C52, independent CAN controller SJA1000, CAN bus driver 82C250. Microcontroller89C52 responsible for the starting of SJA1000, then achieve the communication task of data receive and transmit through the control of SJA1000. It can control the controlled facilities, and make real time data transmission comes true.
