Embodiment 1

[0052] (1) When the device is moving, the camera and thermal infrared imager simultaneously collect images of the surrounding environment, and transmit them to the controller in real time for data processing.

[0053] The image detection process is:

[0054] Firstly, for the image of the thermal infrared imager, identify the hot fault point and send an alarm to the mobile terminal. The mobile terminal can specifically observe the situation of the part by manipulating the camera. If the fault point is located on the cable, further zoom in and shoot through the camera unit.

[0055] For the image collected by the camera: the first step is grayscale processing. Since the captured picture is the internal situation of the overall cable tunnel, the part with the cable needs to be selected for further processing, so the second step is to determine the screening area, conduct cable detection, and identify the part that forms the band-shaped black pixels in the area, and determine it...

Embodiment 2

[0059] The air monitoring module includes methane gas sensor, carbon dioxide gas sensor, volatile organic compound VOC gas sensor. connected to the controller. During the running process, the device monitors the gas conditions in the surrounding environment in real time, and sends the monitored data to the controller. sent by the controller to the mobile terminal.

Abstract

The invention relates to an intelligent device for routing inspection of tunnel cable faults and automatic repair of insulation faults, and belongs to the technical field of tunnel cables. The intelligent device includes a device car body, travelling wheels, a 360-degree panoramic camera, a thermal infrared imager, a supporting rod, an LED head lamp, an air monitoring module, a base, a repair control arm, a supporting arm, an executive arm, an insulation repair assembly and a cable repair piece storage box. According to the intelligent device for routing inspection of the tunnel cable faults and automatic repair of the insulation faults, an insulation repair module is additionally arranged, and the insulation faults can be timely repaired; a way of a mechanical arm heating cable repair pieces to wrap insulation fault points is specifically adopted, meanwhile, the cable repair pieces can be clamped to the mechanical arm automatically without replacing the repair pieces manually, and themultiple fault points can be repaired through once routing inspection; and meanwhile, the basic functions of a cable tunnel routing inspection device such as gas environment monitoring inside a tunnel and real-time data transmission to mobile terminals can be met.

Description

technical field [0001] The invention belongs to the technical field of tunnel cables and relates to an intelligent device for fault inspection and automatic repair of insulation faults in tunnel cables. Background technique [0002] The development of urban modernization has boosted the pace of construction of underground cable tunnels. In super-large cities, the underground power distribution network has tended to be perfected, and large and medium-sized cities are also speeding up the construction of cable tunnels. Due to the complex situation in the cable tunnel, there is water in some areas, and there are small animals like mice, which make the cable easy to reduce its insulation performance due to natural aging, corrosion, and poor ventilation. When the insulation performance of the cable is reduced to a certain level It is easy to malfunction and even cause a fire. Cables need to run safely for a long time. If potential safety hazards cannot be detected early and meas...
