摘要
设计了一种以单片机为控制核心的基于CAN总线电能表自动抄表系统,采用了先进的CAN总线作为系统的通信网络,有效避免了其他抄表方式存在的计量不准、抄表不方便、效率不高等缺点。设计采用了SJA1000 CAN控制器和PC82C250 CAN驱动芯片,使自动抄表系统的稳定性、可靠性和通信距离等都有了很大的提高,经过大量试验和现场测试,结果表明完全克服了现有抄表系统存在的诸多问题,可以满足电能表用户、物业管理部门和供电部门的需求。
Designed the power meter centralized reading system based on CAN bus, using the advanced CAN bus as the communication network , and thus avoid the defaults of the other systerns. This design used the SJA1000 as the CAN bus controllor and PCA82C250 as the CAN bus driver, the design had the high stability, reliability and the distance had improved greatly, and met the user and management requirment.
