Abstract: Consolidated monitoring unit is the key element in implementing the unified communication platform of on-line monitoring system for substation. To solve the problem that some 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 conversion from MODBUS, IEC60870-5 and proprietary protocols to IEC61850. For implementing the access of the monitoring devices by MODBUS protocol, the database and software architecture design of the consolidated monitoring unit were given. And the functions were tested by the standardized information models and the real monitoring devices, by which the reliability and functional integrity of the prototype were verified.
