【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 degree of automation of electric vehicle charging power station is closely related to the performance of its communication network. Good network performance is the premise of timely transmission of data so as to ensure the realization of automatic control and management functions. Therefore, the characteristics and network performance of data transmission in large power station communication networks are worthy of further study. . All kinds of data in the communication network are analyzed and modeled in detail. Then, according to whether the data priority is set in the network, the simulation is carried out by using OPNET software and a series of conclusions are drawn. The calculation results show that. Setting different priorities for all kinds of data is helpful to the timely transmission of important data bureau. In the case of high bit-rate video data transmission, the bandwidth of the network is higher, and it may be necessary to build a separate communication network to transfer video data specially.
