At present, there are two kinds of power transmission lines used in the power grid. One is the more common overhead line, which generally uses uninsulated bare wires, and uses the tower standing on the ground as a support to suspend the wire on the tower, and the other One is the power cable line, which is made of specially processed and manufactured cables, and the cables are buried underground or laid in cable tunnels. With the increasing use of cables, more and more high-voltage lines have to be laid through underground tunnels. However, because the lines of the tunnel are underground, the fault finding and maintenance time of the cable lines is long and it is difficult to monitor the tunnel. This will have a certain impact on the reliability of power grid operation and the normal power consumption of users. If it is impossible to monitor the conditions in the tunnel, it is very easy to cause safety accidents.

This embodiment provides a tunnel comprehensive monitoring system, which can monitor the temperature status of cable joints in real time to avoid the above situation. Please refer to FIG. 1 , the system includes a monitoring and control system 101 , a cable operation monitoring system 102 , and a tunnel environment monitoring system 103.
