The middle cable joint is located in the protective shell 2; the cable joint is located in the cavity of the protective shell 2, as shown in FIG. Figure 3As shown, the monitoring module 1 is preferably installed at the bottom surface of the chamber of the protective shell 2. It monitors the accumulated water, temperature and smoke data in the protective shell 2 in real time through the sensor module 11. The processing module 13 in the monitoring module 1 receives the data collected by the sensor module 11 for processing, and transmits the processed data to the monitoring background 3, so that the operator can understand the cable joint status in real time; the analysis module analyzes the data in the monitoring background 3, determines the status of the cable joint, and transmits the cable joint status to the display operation terminal 7 for display, so that the operator can view it conveniently.

[0044] The sensor module 11 in the monitoring module 1 monitors the temperature, accumulated water and smoke in the protective shell 2 in real time, and monitors whether the cable connector in the protective shell 2 is faulty. The processing module 13 processes the information collected by the sensor module 11, and then sends it to the monitoring background 3 through the second communication module 15. The analysis module 5 analyzes the collected information on the cable connector fault monitoring to determine the status of the cable connector. The operator can obtain timely information through the monitoring background 5 and the display operation terminal 7, which is convenient for the management of the cable connector.

[0045] The protective shell 2 used in the present invention is preferably a modified composite material. The material product has excellent properties such as high flame retardancy and high explosion resistance, and is very suitable for making a cable intermediate joint anti-riot box. The monitoring background 4 receives the information of the cable joint fault monitoring by the sensor module 11 in real time, which is convenient for the operator to understand the cable situation in real time. The display operation terminal 7 displays the data of the monitoring background 3 through the first communication module 6, which is convenient for the operator to view. The sensor module 11 monitors the temperature, accumulated water and smoke in the protective shell 2 in real time to monitor whether the cable joint in the protective shell 2 is faulty. The processing module 13 processes the information collected by the sensor module 11 and then sends it to the monitoring background through the second communication module 15. The analysis module 5 analyzes the collected cable joint fault monitoring information to determine the state of the cable joint.

[0052] The smoke sensor unit 113 is used to monitor the smoke in the protective shell 2 in real time. When the smoke concentration detected by the sensor exceeds the preset alarm threshold, it is judged that a fire or explosion has occurred, and a warning signal is sent to the monitoring background 3 through the processing module 13 to alert the operator.
