Abstract
For the problem that the on-site operation and maintenance of power information collection has no unified standard and lack of technical means, the overall design scheme of the smart checking device for multi-function meter data collection fault is proposed. The carrier module card circuit and system software architecture are designed, and the design principle of the device is analyzed. The fault detection and discrimination methods of carrier module based on online and offline modes are proposed. The fault detection and discrimination methods of field meter and concentrator communication port are proposed. A portable and fully functional field acquisition fault diagnosis and analysis device is developed, which can effectively improve the work efficiency and technical level of on-site operation and maintenance personnel, and plays an important role in promoting the standardization and intelligence of on-site collection and maintenance work.
