基于低压电力线载波及CAN总线的防盗报警系统

Security Alarm System Based on Low Voltage Power Line Carrier and CAN Bus Communication

结合电力线载波通信和CAN总线通信的优点,设计了一种基于电力线载波通信和CAN总线通信的两级总线三层结构防盗报警系统。详细阐述了该系统的总体设计框架、硬件电路及软件设计流程。该系统能完全满足防盗报警系统的实时性要求。户内采用电力线载波通信,具有免布线、稳定可靠、便于扩展的特点,不仅能满足新建小区防盗报警系统的要求,且适用于已建小区的智能化改造。

Combined with the advantage of low voltage power line carrier （PLC） and CAN Bus communication, a kind of two stage bus three layer structure security alarm system based on low voltage PLC and CAN Bus was put forward. The whole system framework and the hardware circuit and software design process are explained in detail. The system can completely satisfy with security alarm system for real-time requirement. With the advantage of stahle and reliable PLC can not only meet the new district requirement, but also can applicable to the intelligence reform old district.
