Aiming at the waste and surplus of charging pile resources caused by unreasonable distribution of charging piles. According to the actual situation, the remote data monitoring of charging piles based on narrowband internet of things (NB-IoT) is designed. Through NB-IoT, all charging piles in multiple regions are monitored in a unified manner, so as to understand the usage of each charging pile in each area. After a period of monitoring and a comprehensive comparison of all data, the usage frequency of charging piles and the amount of electricity used in each area can be obtained. Combined with the actual situation, the charging piles in each area are allocated reasonably. With the STM32103VE chip as the control core, supplemented by the RC522 smart card information acquisition module and the IM1281 power acquisition module, with the support of NB-IoT communication means, the remote data monitoring of charging piles in each area is completed. The test results show that the remote data monitoring of charging piles based on NB-IoT can well monitor the power usage of charging piles in each area, which is of great significance for the reasonable distribution of charging piles.
