蓄电池在线放电数据远程监控系统的研究

Research on online monitoring system of battery large-current discharge data

为了实现实时监测蓄电池在线大电流放电数据,开发了一套远程实时收集在线大电流放电数据的系统。该系统利用现有的大电流测试机和内部的局域网,通过远程网络连接实现蓄电池放电测试数据收集的需求,克服了原有系统只能在现场和USB上载数据才能进行查看分析的缺陷。介绍了利用组态王作为主站,根据下位机记录数据的信号实时读取现场大电流测试机上的PLC放电电流、开路电压、终止电压、放电时间、品质判断等数据,上传到公司服务器。通过Delphi开发的远程监控软件,在内部局域网内的任何电脑都可以实时监控到现场电池的放电数据。

A system is developed to remotely monitor online large-current discharge data of the batteries in real time.By using the existing large-current tester and the internal LAN,the system can implement the collection requirement of battery discharge test data through remote network connection.It overcomes the defect of the old system which can only be viewed in the field or uploaded by USB.In this paper it is described how to use Kingview as the master station,record the data through the Lower Computer,read the PLC discharge current,OCV,cut-off voltage,discharge time,quality inspection in real time,and upload the data to the server.By using the remote monitoring software developed by Delphi,any computer in the internal LAN can monitor the battery discharge data in real time.
