摘要

电动汽车充换电站的自动化程度与其通信网络的性能密切相关，良好的网络性能是数据得以及时传输从而保障实现自动控制和管理功能的前提。因此大型充换电站通信网络中数据传输的特性以及网络性能值得深入研究。首先，对充换电站通信网络中的各类数据进行了详细的分析和建模；然后，针对网络中数据是否设置优先级的情况，利用OPNET软件进行了仿真并得出了一系列结论。计算结果表明，对各类数据设置不同的优先级有助于重要数据局的及时传输；传输较高码率视频数据的场合对网络带宽的要求更高，有可能需要另建通信网络来专门传输视频数据。

Abstract

The automation degree of charging and swapping station of electric vehicles is bounded up with the performance of its communication network. A well-performed communication network is the precondition of transmitting data in time and implementing the functions of automatic control and management. Therefore, the data transmission characteristics in the communication network of large-scale charging and swapping station and the communication performance are worthly studied. Firstly, this paper analyzes and models various data in communication network of charging and swapping station in detail. Then, aiming at the condition whether the data in the network sets priority, this paper carries out numerical simulations with using software OPNET and obtains a series of conclusion. The simulation results show that setting priority tags for different kinds of data is helpful for guaranteeing the reliable transmission of important data. Moreover, if the code rate of video monitoring data is high, a communication network with a broader bandwidth or even a proprietary network for these data only may be demanded.
