地铁直流保护测试系统的研究与设计

Research and Design of Metro DC Protection Test System

随着城市轨道交通的快速发展,对地铁直流保护装置的可靠性要求越来越高,针对大多测试系统只能定性测试的问题,深入研究并设计了一款“工控机+FPGA”嵌入式一体化的地铁直流保护测试系统。该系统现场携带轻便、人机界面直观且测试功能强大,能够全面定量地测试并分析地铁直流保护装置的各类保护逻辑功能,从而满足地铁维护工作人员现场测试、设备厂家产品研发及设备调试等实际需求。

With the rapid development of urban rail transit,the requirements for the reliable performance of Metro DC protection devices are becoming higher and higher.Aiming at the problem that most test systems can only be tested qualitatively,an embedded integrated Metro DC protection test system of"industrial computer+FPGA"is deeply studied and designed.The system is portable on-site,with intuitive man-machine interface and powerful testing functions.It can comprehensively and quantitatively test and analyze various protection logic functions of subway DC protection devices,so as to meet the actual needs of subway maintenance staff on-site testing,equipment manufacturer product development and equipment debugging.
