Problems solved by technology

Most of the existing detection technologies can only detect and locate the faults of communication optical cables or cables alone
At the same time, these technologies all play a role after the fault occurs, but cannot provide information for the prevention of optical cable faults

Abstract

the invention provides a railway safety monitoring system and monitoring method. The system comprises one and more phase-sensitive optical time-domain reflectometers arranged along a railway, corresponding data processing units, coaxial cables, a first network photoelectric transceiver, a communication optical cable along the railway, a second network photoelectric transceiver, and a server. According to the system and method, the railway safety is monitored by employing the conventional communication optical cable, the cost is low, passive distributed detection is realized, electromagnetic interference resistance is achieved, the development of the field of the railway optical cable safety monitoring system is greatly promoted, and good guarantee is provided for monitoring of railway train operation, infrastructure safety, and illegal authorization construction.

Description

technical field [0001] The invention relates to railway safety, in particular to a railway safety monitoring system and monitoring method. Background technique [0002] With the development of my country's railway industry, the importance of railway traffic safety and communication is becoming more and more significant. The safety status of railway communication optical cables is related to the normal operation of the entire railway transportation. However, illegal or illegal construction along the railway often causes the breakage of railway communication optical cables. Traditionally, manual inspections are mostly used, which is inefficient, and is affected by various factors such as the inspectors' sense of responsibility, and the inspection effect is limited.
