中文摘要：

综合监测单元是实现变电站在线监测系统通信统一平台化的关键.为了解决当前变电站非标准化设备无法与IEC61850标准监测系统通信的问题,给出了一种综合监测单元样机的系统结构设计方法.基于Linux的嵌入式平台所设计的综合监测单元样机,可完成将MODBUS、IEC 60870-5以及私有协议向IEC61850标准的转换.针对MODBUS常规监测设备的标准化接入,给出了综合监测单元的数据库设计及其软件结构设计方案;结合实际监测设备的标准化信息及服务模型对其进行了功能测试,验证了样机的设备可靠性及功能完整性.

英文摘要：

Consolidated monitnring unit is the key element in implementing the unified communication platform of on-line monitoring svstem for substation, To solve the problem that so,ne unstandardized devices cannot communicate with the monitoring systems in conformity with standard of IEC 61850. a prototype of a consolidated monitoring unit was developed on the Linux-based embedded platform, which can complete the protocol eonversion from MODBUS, IEC60870-5 and proprietary protocols to IEC61850. For implementing the access of the monitoring devices by MODBUS protocol, the database and software arehitecture design of the consolidated monitoring unit were given. And the functions were tested by the standardized information models and the real monitoring devices, hy which the reliahilitv and funwtional integrity of the prototype were verified.
