SP内嵌eCAN模块在微机保护测控系统中

In this paper, the author designed a microprocessor protection system based on fieldbus CAN technology for the disadvantage of low-rate communications and high data error rate. Combined the enhanced features of CAN controller module, the author designed the microprocessor protection system based on TMS320F2812 in-line with eCAN module, and gave the hardware design scheme; In the design of software, Communicate between the collected information and monitoring computer viaed fieldbus CAN, and carried out real-time remote control and monitoring. Combined the specific application in the microprocessor protection system, the author defined the communication protocol of application layer, introduced the details of part of software design methods and processes, carried a communication experiment, and verified the reliability and accuracy of the system. To facilitate understand the monitoring status for users, the authors designed the LCD and keyboard modules, the system can achieve real-time data and inquire information. The system has been applied to actual production, operates reliable and efficient, has a certain reference value.
