基于CAN总线的数据采集与监控系统的研究

Data Acquisition and Controlling System Design Based on CAN bus

;分析当前国内抄表系统的现状及其存在的主要问题,针对住宅小区智能化的特点,提出了基于CAN(Controller Area Network)总线的数据采集与监控系统的解决方案.介绍了该系统的总体结构、CAN节点智能终端的硬件结构设计,以及系统软件设计.该系统具有灵活方便、可靠性好、通信速率高、抗干扰能力强、通信出错检测等特点,使智能住宅小区的远程抄表、自动实时计量计费与监控系统的集成成为可能.

After the status quo and existing primary problems of meter reading system are analyzed, data acquisition and controlling system is designed based on CAN bus in view of intelligent features of residential area. The design principles and specific realized method of software and hardware are elaborated in the paper. Overall structure hardware structure design of CAN intelligent terminal node and system software design are introduced in the paper. After developing and debugging the system, remote meter reading system and automatic real-time metering and billing system will be possible projects.
