| The electric vehicle charging station monitoring management system is a multiple function terminal, including recharging electric automobiles, billing management and data transmission. In China, during the Tenth Five-Year Plan, we have increased the R&D work of intelligent management system for electric vehicle charging station. For example, BYD has launched the automation management terminal, which has operation and billing functions with unmanned operation. In western countries, mostly the eastern United States, unmanned operation electric vehicle charging station is spread, especially the new ones, which with high intelligence, automation, fully function, free maintenance, etc. Therefore, we realize that establishing the monitoring management system of electric vehicle charging station has very important practical significance.This paper has designed a monitoring management system of electric vehicle charging station, combining networking, wireless sensor network(WSN) and Android technology. The system has four functional modules: data-push, state control, location and database query. In this paper, first is to deploy the monitor nodes, then after initialize these nodes with power, they will spontaneously form a wireless sensor network to do data acquisition, and remotely send data using GPRS module. After serial communication Web server receiving GPRS data transmission, we can access data and send commands using Android interface. The advantage of this model lies in the realization of wireless monitoring and management mode, covering larger area of monitoring and management, and applying to the construction of unmanned mode.Generally, the electric vehicle charging station monitoring management system in this paper includes two parts, one is the data collector and the sender(terminal and coordinator nodes of WSN); the other is the visual interface of electric vehicle charging station monitoring management system(APP application software based on Android platform of electric vehicle charging station monitoring management), but the two systems cannot communicate directly. Therefore, with Web server technology, firstly we put forward the design system with communication function based on HTTP and XMPP communication protocol, in which HTTP communication services mainly guarantee the data and control command forwarding; based on push function of communication protocols, XMPP is responsible for the system warning content push. This is also the innovation of this paper. Secondly, based on the Android device APP, electric vehicle charging station monitoring management system software development use the Java language and mature Android SDK development environment, through the SQLite database engine implementation Android structured data storage. In this paper, the electric vehicle charging station monitoring management system has carried on the detailed design, implementation and testing on the technology, through the system test, this paper has reached the setting goal with a certain application value and market prospect. |
