| 汽车充电桩建设要求 Car charging pile construction requirements 汽车充电桩建设要求。作为电网配用电侧的电动汽车充电桩(栓)，其结构的特殊性决定了自动化通信系统的特点是被测点多且分散、覆盖面广、通信距离短。并且随着城市的发展，网络拓扑要求具有灵活性和扩展性的结构，因此，电动汽车充电桩(栓)通信方式的选择应考虑如下问题：(1) 通信的可靠性——通信系统要长期经受恶劣环境和较强的电磁干扰或噪音干扰的考验，并保持通信的畅通。(2) 建设费用——在满足可靠性的前提下，综合考虑建设费用及长期使用和维护的费用。(3) 双向通信——不仅能实现信息量的上传，还要实现控制量的下达。(4) 多业务的数据传输速率——随着以后终端业务量的不断增长，主站到子站、子站到终端之间通信对实现多业务的数据传输速率要求越来越高。(5) 通信的灵活性和可扩展性——由于充电桩(栓)具有控制点面多、面广和分散的特点，要求采用标准的通信协议，随着“ALL IP”网络技术趋势的发展以及电力运营业务的不断增长，需要考虑基于IP的业务承载，同时要求便于安装施工、调试、运行、维护。 Car charging pile construction requirements. As electrical side of power grid with electric vehicle charging pile (bolt) and the particularity of its structure determines the characteristics of automation communication system is by measuring point more and scattered, wide coverage, communication distance is short. And with the development of the city, the network topology with the structure of the flexibility and extensibility, therefore, the electric car charging pile (pin) communication mode selection should consider the following questions: (1) the reliability of communication - communication system to withstand harsh environment for a long time and strong electromagnetic interference or noise interference test, and keep the communication open. (2) construction expenses - the cost of construction and the cost of long-term use and maintenance shall be taken into account under the premise of satisfying reliability. (3) two-way communication -- not only can the amount of information be uploaded, but also the control quantity. (4) the more data transfer rate of the business, as the terminal after business growing, between the main and sub station, station to the terminal communication to realize the data transfer rate of the business demand is higher and higher. Flexibility and scalability of the (5) communication, due to the charging pile (pin) with control points, face more wide range and the characteristics of dispersion, require the use of standard communication protocol, with the development of "ALL IP" network technology trends and growing power operation, need to consider based on IP bearer, at the same time requirements to facilitate installation, commissioning, operation, maintenance. |
