Embodiment 1

[0047] A cable trench inspection system, comprising: a control module, an infrared camera, a water level sensor and a communication module;

[0048] The infrared camera and the water level sensor are respectively electrically connected to the control module;

[0049] The infrared camera is used to collect temperature signals and image signals in the cable ditch, the water level sensor is used to collect water level signals in the cable ditch, and the control module is used to collect the temperature signal according to the set value when the temperature signal exceeds the first set value. Analyze the image signal to obtain the type of foreign matter entering the cable trench and send an alarm signal through the communication module. The control module is also used when the temperature signal exceeds the second set value or the water level signal exceeds the third set value. An alarm signal is sent through the communication module.

Abstract

The invention relates to a cable trench inspection system which comprises a control module, an infrared camera, a water level sensor and a communication module. The infrared camera and the water level sensor are electrically connected with the control module. The infrared camera is used for collecting a temperature signal and an image signal in the cable trench, and the water level sensor is used for collecting a water level signal in the cable trench. The control module is used for analyzing according to the image signal to obtain the type of the foreign matter entering the cable trench when the temperature signal exceeds a first set value and sending an alarm signal through the communication module. The temperature and the image in the cable trench can be collected through the infrared camera, and when the temperature reaches the first set value, the image is analyzed; if the foreign matter exists, an alarm signal is transmitted through the communication module, and a worker can know that the interior of the cable trench is abnormal after receiving the alarm signal, so that the worker can arrive at the site at the first time and troubleshoot the cable trench.
