虚拟MODBUS协议在电气试验车中的应用

Application of Virtual Modbus in Electrical Testing Coach

针对当前电气试验车集控系统中电力检测设备通信协议不统一的现状,在电气试验车研发中采用了全新的虚拟现场总线Modbus协议技术,将软件组态和硬件组态理念紧密结合,克服了不同厂家不同类型设备与试验车监控主机之间的通讯协议匹配问题;通过虚拟Modbus协议服务器软件提供标准化访问接口,使电气试验车测控软件可以用统一的方式控制各个检测设备,提高了电气试验车的系统集成度和设备兼容性;该方法的成功运用,也为高压电气试验设备通讯功能的标准化起到一定推动作用。

Because of the different communication protocol of electrical testing equipment , the new virtual Modbus Technology is used in electrical testing coach. The technology solves the communication matching problem of different equipment and monitoring host in electrical testing coach. The server software of virtual Modbus protocol provides the standardized access interface of different equipment. The soft im- proves the system integration and device compatibility of electrical testing coach, and the method promotes the communication function stand- ardization of high voltage test equipment.
