Cable trench temperature measuring system and method

The invention discloses a cable trench temperature measuring system and method. Linear temperature measuring cables arranged in cable trenches are used for collecting the highest temperature data of the cables in the cable trenches, temperature monitoring on the cable trenches is achieved, and the phenomenon that according to a point mode temperature measuring method, dead zones exist is avoided; a remote monitoring system is used for carrying out remote monitoring on temperature data so that workers can monitor the cable trenches in real time; when it is monitored that the temperature of a cable trench at some location is overhigh, the workers can carry out troubleshooting on the situation of the cable trenches in time according to a monitoring result, the phenomenon that the temperature in a cable trench is overhigh, a cable is on fire, and accidents are caused is avoided, and the problems that according to manual measurement on the temperature of cable trenches, working difficulty is high, and the workload is high are solved.
