基于NB-IoT的充电桩数据监控及合理分配*

针对充电桩分配不合理而导致的充电桩资源浪费,过剩等情况。从实际情况出发设计了基于NB-IoT的充电桩远程数据监控,通过窄带物联网(NB-IoT)手段,把多个地区的所有充电桩进行统一的监控,进而去了解每个地区中每一个充电桩的使用情况。在进行一段时间的监控之后,对所有数据进行综合比对之后,便可以得到每个地区充电桩的使用频率以及电能使用量。结合实际情况进而对每个地区的充电桩进行合理的分配。以STM32103VE芯片为控制核心,同时辅以RC522智能卡信息采集模块和IM1281电能采集模块,在NB-IoT的通信手段的支持下,完成对每个地区充电桩的远程数据监控。测试结果显示,基于NB-IoT的充电桩远程数据监控能够很好的监测到每个地区中充电桩的电能使用情况,这对于合理分配充电桩有着非常重要的意义。

Data monitoring and reasonable distribution of charging piles based on NB-IoT

Aiming at the waste and surplus of charging pile resources caused by unreasonable distribution of charging piles. Based on 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 frequency of use of charging piles and the amount of electricity used in each area can be obtained. According to 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, 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.
