基于Echarts的地铁屏蔽门数据监控系统的实现

Implementation of data monitoring system of subway shielding gate based on Echarts

针对地铁屏蔽门状态监控问题,以上海申通地铁2号线屏蔽门控制系统为研究对象,设计了基于Echarts的可视化地铁屏蔽门数据体系监控系统。整个系统分为8个子模块,实时显示、状态量显示、模拟量时序图、预警、历史报警、历史记录、设置、回放。实时显示模块,通过继电器传回的状态值,动态模拟地铁屏蔽门的开关状态,在状态量显示模块和模拟量时序图模块,采用了Echarts可视化技术,分别通过时序图和折线图的形式展示,开门继电器和门锁闭继电器的状态信息和电压电流值,通过滑动条查询不同时间段对应的信息,通过折线图的波动情况可以知道屏蔽门的运行状态,达到实时更新,实时监控的作用。并将回传的信息保存在数据库中,方便以后查询。

Aiming at the status monitoring of metro shield door,a visual monitoring system of metro shield door data system based on Echarts is designed based on the control system of Shanghai Shentong Metro Line 2 shield door. The whole system is divided into8 submodules,which are real-time display,state display,analog sequence diagram,early warning,historical alarm,history record,setting and playback. The real-time display module dynamically simulates the switching state of the shield door through relays. In the state display module and the analog sequence diagram module,the Echarts visualization technology is adopted,respectively through the sequential diagram and broken line diagram form. The status information,voltage and current value of the subway platform door open relay and door lock relay are displayed,and the corresponding information of different time period is inquired through sliding bar. Through the fluctuation of the broken line diagram,the running state of the shield door can be known,and the function of real-time updating and real-time monitoring can be achieved. The returned information is saved in the database for convenient inquiry later. After the implementation of the system,the system is deployed.
