通过分析接触网接触悬挂张力变化,研制了一种安装在接触悬挂下锚终端的张力在线监测系统。当接触悬挂因补偿装置卡滞或断线而引起张力超出允许数值时,通过GSM网发出短信预警信息,以及时发现接触悬挂异常和预防断线事故的发生,并在发生接触网断线事故后能起到快速查找的作用。本文重点介绍了接触网张力在线监测系统的实现方案和软硬件工作原理。
By analyzing the change of the contact tension of the contact net, an on-line tension monitoring system was developed, which was installed on the anchor terminal of the contact suspension. When the contact suspension due to the compensation device stagnation or disconnection caused by the tension exceeds the allowable value, send SMS warning information through the GSM network, and timely detection of contact suspension anomaly and prevent the occurrence of a disconnection accident, and in the event of a contact network disconnection accident Can play a role in quick search. This article focuses on the catenary tension online monitoring system implementation programs and hardware and software work principle.
