Tunnel Inspection Robot with Infrared Thermal Imaging Function
With the rapid development of modern urban construction, it has become a development trend for overhead lines to enter the ground. At the same time, various cable tunnels have also developed rapidly. At present, cable tunnels can be roughly divided into three forms: open-cut tunnels, shield tunnels and pipe jacking tunnels. The main features are long distances, complex topography, and multiple and intricate cable types. Here comes a great challenge. Therefore, in order to effectively complete the inspection of the cable tunnel, the infrared thermal imaging tunnel inspection robot has gradually become the best tool to replace the manual inspection.
For the infrared thermal imaging tunnel inspection robot, a reasonable walking mechanism is the basis and key for the robot to complete obstacle avoidance and obstacle crossing actions, and realize normal inspection work. At present, the walking mechanism of the infrared thermal imaging tunnel inspection robot is mainly divided into two types: ground walking type and overhead track type. The ground walking robots can be divided into two types: wheel walking robots and crawler walking robots. Wheeled walking robots are easy to control, but difficult to overcome obstacles, and have high requirements for the tunnel ground environment. Compared with wheeled walking robots, crawler-type walking robots have an improved ability to overcome obstacles, but their operation is difficult and expensive. Compared with ground-walking robots, overhead tunnel inspection robots are easier to control and are not disturbed by the cable tunnel road environment. At the same time, they have the characteristics of simple structure, mature technology and better inspection efficiency.

The use of infrared thermal imaging tunnel inspection robot has the following more advantages.
(1) Reduce Operation and Maintenance Costs. Before the intelligent inspection robot technology, the measurement team mostly chose manual and camera-equipped robots to complete the shooting and measurement work, which consumed a lot of labor costs. The infrared thermal imaging tunnel inspection robot replaces manual equipment to a certain extent to complete the equipment inspection work. In terms of operation and maintenance costs, only the basic maintenance of the robot body is required on a regular basis, which can reduce the application of a large number of video monitoring equipment costs, regular operation and maintenance costs, and the disassembly and assembly of malfunctioning devices, and reduce the difficulty of maintenance.
(2) Special Environmental Applications. The infrared thermal imaging tunnel inspection robot can be used in harsh weather conditions, and can adjust the inspection mode in combination with different ground heights and different operating speeds, which greatly improves the resolution of obtaining data. In fact, , The resolution of the infrared thermal imaging tunnel inspection robot is higher than that of the satellite. In addition, the infrared thermal imaging tunnel inspection robot has less human intervention during the comprehensive pipeline corridor inspection process, which reduces the probability that the data obtained by the inspection is affected by human factors, thereby improving the accuracy of the inspection results.
(3) Remote Sensing Technology. The infrared thermal imaging tunnel inspection robot not only includes remote sensing information collection and collection technology, but also remote sensing information processing technology, which makes the application of robot technology in the comprehensive pipeline inspection work with a high degree of integration and macroscopicity, and can be realized Coordination application between various detection systems. In addition, the infrared thermal imaging tunnel inspection robot is small in size and convenient to operate. It can complete information collection through a relatively small space. This means that the inspector can adjust the operating speed and height of the intelligent inspection robot to perform larger tasks.
