|
摘要
高压开关柜单一状态量检测难以实现通信资源和信息共享的问题一直以来总是困扰着电力公司的相关人员,针对此问题,文章设计了基于Modbus总线模式的高压开关柜机、电、热3种状态在线检测系统。系统采用一主多从控制模式,实现了上位机与多面开关柜的多个传感器的信息通信和数据传输。结合高压开关柜各状态量检测传感器的工作特性,提出了3种系统控制模式,保证了检测系统的高效性和可靠性。通过开展现场测试实验,验证了系统的有效性。
To solve the problem that communication resources and information sharing are difficult to be realized in the detection of single state quantity of high voltage switch cabinet in the past, an electricity and heat three states online detection system for high voltage switch cabinet based on modbus bus mode is designed. The system adopts one master and multiple slaves control mode to realize the information communication and data transmission of multiple sensors between the upper computer and the multi-face switch cabinet. In combination with the working characteristics of each state quantity detection sensor of the high-voltage switch cabinet, three system control modes are proposed in this paper to guarantee the high efficiency and reliability of the detection system. The effectiveness of the system was verified by field test.
