摘要
传统系统资源占用压力较大,写入时间较慢,难以满足自动管理要求,提出基于CIM模型的轨道交通电源自动管理系统设计。基于CIM模型对数据进行实时采集、实时计算和实时追踪,设计硬件结构,并分别对过压欠压管理和过流管理展开研究;构建轨道交通电源管理系统的软件结构框图,并对数据通讯接口、数据存储、数据建模和可视化平台依次进行分析;设计对比实验,得出实验结论。由实验结果可知,该系统与传统系统相比,改进系统的CPU使用率只有10%,写入时间为0. 12s,资源占用压力小、CPU使用率缩小4倍,写入时间快0. 38秒,既节省了时间,又降低了成本。
The traditional system resources occupy much pressure and the writing time is slow, so it is difficult to meet the requirements of automatic management. Based on the CIM model, the automatic management system of rail transit power is designed. CIM model is used for data collection, real-time calculation and real-time tracking based on the design of the hardware structure,and the overvoltage and undervohage and overcurrent management management research;software architecture construction of rail transit power management system, and the data communication interface,data storage,data modeling and visualization platforrn are analyzed ;the design comparison the experiment,draw a conclusion of the experiment. The experimental results show that the CPU utilization rate of the system is only 10%, the writing time is 0. 12s,the resource occupancy pressure is small,the CPU utilization rate is reduced by 4 times,and the writing time is 0. 38 seconds,which saves time and costs.
