| In the context of the world’s scarcity of resources and the increasing environmental pollution in my country,new energy electric vehicles will undoubtedly become the future direction of automobile development.As a kind of green transportation with broad development prospects,electric vehicles will be popularized very rapidly in the future,and the future market prospects will also be extremely huge.As the core of electric vehicles,charging piles are an indispensable part.At present,the supervision of charging piles by some enterprises stays in manual inspection and inspection.This inspection is not only inefficient but also prone to errors.Although some enterprises conduct remote monitoring through communication systems,the monitoring area is relatively limited and only suitable for local monitoring.Not only that,when the distribution of charging piles is unreasonable,it will inevitably lead to waste and excess of charging pile resources.First,according to the analysis of system requirements,the STM32F103RCT6 chip is selected as the control core,and the FM1702 smart card information acquisition module,DHT22 temperature and humidity information acquisition module and JSY-MK-156 electric energy acquisition module are used as data acquisition modules.Then,with the support of NB-IoT and CAN bus communication means,remote data monitoring of charging piles in each area is completed.Finally,the management platform is designed with JavaEE,which can realize the functions of charging pile management,charging station management,charging rules,charging pile monitoring and alarm management,and complete real-time online monitoring of charging piles.After using for a while,every time the charging pile fails,the alarm information can be sent in time,and at the same time,the frequency of use of the charging pile in each area and the amount of power consumption can be obtained.The charging piles in the area shall be allocated reasonably.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 and the processing of alarm information,which is useful for real-time online monitoring of the usage and reasonable distribution of charging piles.Charging piles have a very important meaning.Figure 46;Table 3;Reference 59... |
