Through intelligent visual recognition and video functions, the intelligent inspection robot can effectively check the status of the protection plate, indicator light, knife switch position, and knob of the power distribution cabinet; infrared thermal imaging is used to detect the temperature of the switch cabinet knife switch position. The telescopic partial discharge sensor can perform partial discharge detection on the switchgear.

In addition, it triggers the linkage inspection with the integrated protection device of the switchgear to realize the automatic inspection of the equipment in the power distribution room and the linkage inspection of the accident. The robot can also rotate up and down at multiple angles, and the longest extension can reach 1.6 meters, ensuring multi-directional coverage of inspection points, realizing fault warning, and improving inspection efficiency.

The robot can upload the collected data in real time, so that the staff can check the current and historical patrol data at any time. In the centralized control center, on-site staff are watching the robot's working conditions and related data through the computer display screen to ensure the safe and reliable operation of the power supply equipment in a timely and effective manner.

2 Extra-long tunnel Yan-Chong Expressway

Intelligent inspection robot "on duty"

The Hebei section of Yan-Chong Expressway is a major traffic guarantee project for the 2022 Beijing Winter Olympics and a pilot project for smart highways by the Ministry of Transport. The Jinjiazhuang Spiral Tunnel is located near Jinjiazhuang Village, Paoliang Township, Chicheng County, Zhangjiakou City, Hebei Province. The left side is 4228 meters long and the right side is 4104 meters long. In August 2019, the tunnel was recognized as "the world's longest highway spiral tunnel".
The first highway tunnel intelligent inspection robot in Hebei Province can collect and monitor the tunnel environment and traffic operation in real time, analyze and predict the information, and provide strong technical support for highway tunnel emergency rescue.
It is reported that there are two smaller robots at both ends of the tunnel, a total of three robots, one master and two slaves. Normally, the main robot is responsible for the inspection work. Once it fails, the other two standby robots will automatically transfer work and continue to complete the inspection work.

3. The first domestic inspection robot for the return air lane

Put into use in Zhangjiamao, northern Shaanxi

The first domestic return air lane inspection robot adopts the wire rope suspension traction drive mode. By carrying gas sensors, visible light sensors, wind speed sensors and other high-precision sensors, it overcomes the structure design of the complex environment of the coal mine, the image recognition and the strong Difficulties such as environmental perception under disturbance conditions.

It broke through the energy control technology of low-power robots, pioneered key technologies such as water accumulation area recognition technology, roadway deformation monitoring, etc., improved steady-state control in strong turbulent environments, and sensing accuracy in high dust and high humidity environments. Using 5G /WIFI hybrid communication technology, to realize the functions of independent detection of return air tunnel variables, intelligent identification of water accumulation area, automatic gas monitoring, alarm, etc., and upload the above information to the ground sub-control center to realize the state of the ground sub-control center to the return air lane Real-time monitoring.

The use of the return air lane inspection robot solves the complex environment of the return air roadway, the long distance of personnel inspection, and the long time. It has realized the long-distance inspection with an inspection life of up to 5 hours, and each shift can be reduced. 2 inspectors of the return air tunnel. The investment of the robot plays an important role and demonstration value for exploring and promoting the practical application of coal mine robots, reducing people and increasing efficiency in coal mines, and building smart mines.

4. China Mobile opens

New era of intelligent indoor inspection

No matter in the power room or IDC room, operation and maintenance personnel will always encounter various problems in daily inspection work, such as complex environment, huge workload, high manual recognition error rate, and untimely response to emergencies Wait. When faced with these complicated situations, only an intelligent inspection robot can be used to solve them.

China Mobile's intelligent inspection robot can realize high-frequency, large-scale, and intelligent inspections without blind spots, improve the stability and real-time performance of the operation and maintenance of the computer room, reduce the work intensity of the operators, and greatly improve the accuracy of equipment defects and fault finding Sexuality and timeliness.

5. Nuclear radiation inspection robot

Escorting the development of the nuclear industry

With the improvement of nuclear power technology and the public’s high attention to nuclear safety, the continuous breakthroughs in key technologies such as radiation resistance technology for electrical components, radiation resistance technology for robot systems, and system reliability technology have not only been used in special environments. Emergency repair of nuclear power plant. Using advanced robotics technology to solve complex operations such as routine maintenance, radiation monitoring and even accident handling in the special environment of nuclear power plants has become a hot spot for global development.

For the inspection field of nuclear industry radiation monitoring, robots need to be able to ensure normal work at least in a 1Sv environment. The focus of the development of robots is the information collection ability and transmission performance in complex environments. At present, companies have designed and developed nuclear radiation inspection robots, and are open to sales in the nuclear industry and scientific research fields to escort the development of the nuclear industry.
