Research and design of transmission line condition monitoring agent

Because of the problem that there is not a unified transport protocol and data storage for the existing transmission line on-line monitoring devices, a kind of on-line monitoring device named condition monitoring agent(CMA) was designed to replace the old on-line monitoring devices to communicate with master system. A design based on the combination of S3C2440 and Linux was put forward. The communication interface named I1 which is used for data transmission between CMA and monitoring equipment, as well as the communication interface named I2 which is used for data transmission between CMA and master system were designed. The technology of low power was realized in CMA. In the same time, the transport protocol was unified. That the EMC has been completed proves that CMA can work normally in the electromagnetic field environment. This system has been in operation in the interconnection project from Qinghai to Tibet. CMA runs in good condition, it can effectively guide the high-voltage transmission line operation and maintenance management.
