It is of great significance for the stability and optimal operation of the power grid to find and control the abnormal conditions in the operation of the distribution system in time. According to the current situation of distribution network and the demand of distribution automation in China, aiming at the problems existing in the cost, accuracy, communication and reliability of distribution monitoring terminal, this paper puts forward a design scheme of distribution monitoring terminal with arm as the control core and high-precision power measurement chip as the data collection core, and designs the serial communication between computer and power transmitter. Communication protocol, and completed the production of the prototype.
