摘要
介绍了基于CDMA2000-1X分组数据网络构建的铁路枢纽站场接触网隔离开关无线集中监控系统。该系统利用CDMA 1X分组域的VPDN专线网,结合传统的调度自动化技术,在监控主站构建数字化多功能信息平台,实现了对隔离开关运行状态的监控,该系统使用公用信息平台作为远动数据传输通道,降低了系统的建设和使用费用,节省资源成本,提高了铁路牵引供电管理的自动化水平和操作的安全可靠性。实际运行结果表明,该系统具有良好的可靠性、灵活性和可扩性。
A railway wireless control mode of isolating switch monitoring system is designed based on CDMA2000-1X. VPDN of CDMA 1X is utilized here, combined with traditional dispatching and automation technology, a digital multifunctional information platform is built in the scheduling center. The mornitoring management of the isolating switch are realized here. The system utilizes public information platform as the channel of SCADA data transmission, having reduced systematic construction and usage cost, having economized resource cost, having raised a railroad dragging the administrative automation supplying electricity horizontal and handling. It is proved that this system does good on reliability, flexibility and expansibility.
