Abstract

The invention discloses a monitoring system for railway track bolt looseness. The monitoring system comprises a laser emission module, a track fiber, a cutting device, a laser receive module and a processing circuit module. The processing circuit module comprises an electromagnetic relay, an alarm circuit module and a control circuit module used for controlling a railway track system. The cutting device is used for cutting off the fiber when a bolt loosens. When the railway track bolt loosens, the cutting device cuts off the fiber, the laser receive module can not receive a light signal, so an alarm is given; meanwhile, a railway track relay circuit is cut off. The invention further discloses a monitoring method for railway track bolt looseness. According to the monitoring system and the monitoring method for railway track bolt looseness, the looseness condition of the railway track bolt is systematically monitored in real time; in addition, the design process and the manufacturing process are simple, the price is low and large-scale manufacturing and application are facilitated.

Description

technical field [0001] The invention relates to the technical field of optical fiber-based sensing and monitoring, in particular to a monitoring system and method for monitoring the looseness of railway track bolts. Background technique [0002] Since my country's first train speed increase in 1997, my country has successively built and opened Beijing-Tianjin intercity passenger trains, Beijing-Shanghai intercity passenger trains, and Beijing-Guangzhou intercity passenger trains. The design speed has gradually increased from 200 kilometers per hour to 350 kilometers. China has built a high-speed railway network with the longest mileage, the largest investment and the highest standards in the world. By 2020, through the construction of new high-speed railways, passenger trains and the comprehensive upgrading and transformation of existing railways, a "four horizontal and four vertical" rapid railway passenger transportation network with a total scale of about 16,000 kilometer...
