中文摘要：
低压电力线载波通信利用原有供电线路,免去重新布线之苦,非常适用于诱导通风智能控制系统;设计了基于LPC2132（ARM7）与ST7538的低压电力线载波通信诱导风机控制系统,对系统的主要电路作了设计,包括基于LPC2132与ST7538的控制器电路连接图、电力线载波通信接口、CO检测、烟雾检测等模块电路;讨论了主/从通信过程、风机控制及系统的软件设计;系统主要用于地下停车场、地下商场、大型场馆等需自动通风及防火的场所;该设计方案与传统的总线式通风控制系统相比,具有系统构建简单、成本低、即插即用、抗干扰能力强、调试维护方便等优点,具有一定实用价值。
英文摘要：
Low-Voltage power lines carrier communication using the existing power lines,replacing the pain of re-wiring,it is ideal for intelligent control system induced by ventilation.Control system of low-voltage power lines carrier communication for inductive ventilation are designed based on LPC2132（ARM7） and ST7538.The main circurts are designed,including controller of circuit connection diagram based on the LPC2132 and ST7538,the interface circuit design of voltage power lines carrier communication;the module circuit of CO detection and smoke detection;Discussed the master/slave communication process and designed the fan＇ control and system software.The system is mainly used for underground parking,underground shopping malls,stadiums and other large-scale place.The design has the simple construction,low cost,plug-and-play,anti-interference ability,debugging maintain convenience etc,it has some practical value.
