【摘要】：随着能源短缺和环境污染的日益严重,国家开始加大对能源环境的治理,电动汽车逐渐进入人们的视野。作为电动汽车的基础设施,充电站的建设已经迫在眉睫,因此与之配套的充电站监控系统的开发与研究有着重要的意义。本文基于.NET平台,通过对电动汽车充电站的整体结构的研究,开发设计了一套监控系统实现对电动汽车充电站的整体监控。首先,对充电站监控系统进行需求分析并设计了它的整体结构,系统主要分为充电监控和配电监控两大部分。充电监控负责对充电桩、充电机、消费金额、电池电量和BMS参数的采集与监控;配电监控负责对高压室、变压室和低压室仪表的数据采集与分析。其次,根据需求对硬件进行了选型与分析。针对系统需求和硬件接口对CAN以太网转换器、配电室仪表、多串口卡进行选型。给出了直流充电桩、交流充电桩和充电桩控制器的硬件组成。再次,根据硬件的选型对监控系统的通信进行设计与实现。根据硬件接口,设计了充电站的整体通信方案,制定了充电通信规约,并根据通信规约进行了通信实现。详细研究了充电流程,实现了数据服务器的数据备份。最后,对充电站监控系统的软件进行设计与实现。设计了监控软件的总体框架,主要包括数据显示模块、通信模块和数据库模块三大部分。开发了充电站监控系统,实现了数据采集、计费处理、监控分析等功能,并对数据库进行了优化处理。
[Abstract]:With the increasingly serious energy shortage and environmental pollution, the country began to strengthen the treatment of the energy environment, and electric vehicles gradually entered the people's field of vision. As the infrastructure of electric vehicle, the construction of charging station is urgent, so it is of great significance to develop and research the monitoring system of charging station. Based on. Net platform, through the research of the whole structure of electric vehicle charging station, this paper develops and designs a set of monitoring system to realize the whole monitoring of electric vehicle charging station. First of all, the requirements of the charging station monitoring system are analyzed and its overall structure is designed. The system is divided into charge monitoring and distribution monitoring. Charge monitoring is responsible for collection and monitoring of charging pile, charger, consumption amount, battery power and BMS parameters, and distribution monitoring is responsible for data acquisition and analysis of high-voltage chamber, transformer room and low-voltage chamber instrument. Secondly, according to the requirements of the hardware selection and analysis. Can Ethernet converter, switchroom instrument and multi-serial card are selected according to the system requirement and hardware interface. The hardware components of DC charging pile, AC charging pile and charging pile controller are given. Thirdly, the communication of the monitoring system is designed and implemented according to the hardware selection. According to the hardware interface, the whole communication scheme of the charging station is designed, the charging communication protocol is established, and the communication is realized according to the communication protocol. The charging process is studied in detail, and the data backup of the data server is realized. Finally, the software of the charging station monitoring system is designed and implemented. The overall framework of monitoring software is designed, including data display module, communication module and database module. The monitoring system of charging station is developed, which realizes the functions of data acquisition, billing, monitoring and analysis, and optimizes the processing of database.
