组态王和VB在远程定位中的应用

Kingview and VB applications in remote positioning

为了利用组态王6.53接收远程数据功能和VB(Visual Basic)对MapX控件进行二次开发功能,利用DDE(Dynamic Data Exchange)技术,实现了组态王6.53与VB通信,根据组态王通信使用的MODBUS协议格式和GPS(Global Positioning System)数据格式,来提取经纬度信息,以此控制动态图层中的图元,来而实现远程车辆的定位,同时也扩大了监控中心软件的功能。

To take advantage of receiving remote data functions of Kingview 6.53 and VB（Visual Basic）with the secondary development function of MapX control,using DDE（Dynamic Data Exchange） technology to realize Kingview 6.53 and VB communications,dependingon the MODBUS protoco lformat of Kingview communication and the data format ofGPS（Global Positioning System）,to extract the latitude and longitude information,to controlf the pixel of the dynamic layer,this paper realizes the remote vehicle location and also expands the function of monitoring center software.
