摘要
介绍基于CAN总线和P87C591单片机的数据采集处理系统。P87C591是具有片内CAN控制器的8位高性能微控制器,简化了硬件电路的设计。利用CAN总线结构灵活简单,可靠性高,适应性好,易于维护等优点,方便的实现了与上位机的数据通讯,并利用上位机强大的数据处理能力,实现事件记录和数据处理等功能。
The thesis introduced the design of the date acquisition and application based on CAN Bus. The P87C591 is a single-chip 8-bit-high-performance microcontroller, with on-chip CAN-controller, simplifying the circuit design of hardware. CAN Bus have integrated specialty of flexible and simple structure, high reliability, good adaptability, and easy maintenance, so it is used to meet the demands for real time performance of data communication. On-site data is transmited to the host computer. The system can make using of the strong data processing of the host computer to realize the function of measure the power parameter, event record automation and data application.
