基于CAN的漏电报警网络系统

Electric Leakage Alarm Network System Based on CAN

设计了一套基于CAN总线的漏电报警网络系统,系统包括远程监控模块、中间控制柜机、中央监控主机三个层次,各层间均采用CAN总线通信。设计中采用模块化思想,每一层次的监控单元既可与下层单元独立构成监控系统,又可与上层联网成为更大范围监控系统的组成部分。系统采用电子地图系统,能迅速定位网络节点故障及漏电报警位置。文中给出了网络系统各层的软、硬件设计。

An electric leakage alarm network system based on CAN was designed, in which remote monitoring terminal, control station and central monitoring PC were served as bottom, medial and top unit individually. Adjacent layers of network were connected with CAN. Each unit and its lower-level ones could not only build up an individual monitoring system, but also become a component of the large-scale monitoring system. Electronic map was used in the electric leakage alarm network system, and the fault and leakage positions were located quickly. The design of software and hardware for every layer were presented.
