Design of Leakage Alarm Control System for Fire Water Pipeline Entering Substation

文章提出了变电站进站消防用水管道泄漏告警控制系统设计方法。该系统主要分为检测控制和远程告警控制2部分,前者以ATmega328单片机为控制芯片,后者采用变电站内辅控系统平台进行二次开发,两者通过ZigBee无线通信模块进行通信。检测控制部分通过水流量传感器采集管道内的水流动态变化反应管道异常并通过ZigBee无线通信模块上传至远程告警控制部分;同时接收运维人员下达的远程指令对电磁阀进行控制,进而及时关闭管道。

This article proposes a design method for a leakage alarm control system for fire water pipelines entering substations.The system is mainly divided into two parts:detection control and remote alarm control.The former uses the ATmega328 microcontroller as the control chip,while the latter uses the auxiliary control system platform in the substation for secondary development.The two communicate through the ZigBee wireless communication module.The detection and control part collects the dynamic changes of water flow inside the pipeline through a water flow sensor to reflect pipeline abnormalities,and uploads them to the remote alarm control part through the ZigBee wireless communication module;Simultaneously receiving remote instructions from operation and maintenance personnel to control the solenoid valve and promptly close the pipeline.
