[0002] The current 10kV power distribution overhead line is undergoing power grid transformation and upgrading. By adding feeder automation terminals and fault indicators, the intelligent information collection and monitoring capabilities of the distribution network site are enhanced, and remote fault identification, positioning and isolation are performed at the same time. Power supply reliability of the distribution network; during the transformation and upgrading of the power grid, the information exchange between terminals of different manufacturers on the distribution network site or the data transmission between the main station and the terminal mostly adopts the wireless public network mode, which is installed on the overhead line tower or line Due to factors such as difficulty in obtaining power, difficulty in operation and maintenance, and performance requirements of the equipment itself, the terminal equipment has strict restrictions on equipment power consumption, and the requirements for the software and hardware design of data communication devices, wireless communication network transmission performance and low power consumption of equipment are gradually increasing. , In addition, due to the insufficient standardization of internal software and hardware modules of power distribution terminal products, strong coupling, low versatility of modules, and low internal integration efficiency of equipment, there is no interoperability between terminal products of different manufacturers, especially as an external Due to many different factors such as technical realization level, personnel quality, and underlying platform of the connected communication modules, there have been problems in communication interoperability, unified processing and batch remote operation and maintenance in distribution network data communication for a long time. Therefore, integrated wireless communication is needed Universal power distribution data transmission device designed for network transmission performance and equipment low power consumption requirements
