Power Inspection Robot
Product Features
Product Parameters

The power inspection robot integrates professional technologies such as artificial intelligence, intelligent control, information processing, image processing, detection and measurement, and cross-computer, automatic control, mechanical, electronic and other multidisciplinary cross-intelligence.

The key technologies of intelligent inspection robots are mainly : VSLAM and laser hybrid navigation technology, multi-sensor information fusion technology, robot controller and intelligent protection system technology.

At present, power inspection robots have been put into the daily operation of the power industry. The use of intelligent power inspection robots helps substation technology upgrades, reduce labor costs, improve detection accuracy, and provide a solid technical guarantee for the intelligent development of substations; the promotion and application of intelligent power inspection robots will further improve power production operations. The level of automation provides more protection for safe production of electricity.


Functional characteristics

● Trackless navigation: with international advanced VSLAM and laser hybrid navigation technology, can achieve millimeter precision navigation and obstacle avoidance.

● Four-wheel drive: four-wheel independent drive chassis, can be turned in place, with the ability to adapt to complex roads.

● Intelligent inspection: support one-button start, timing execution, path inspection, multi-machine cooperation, network return.

● Intelligent alarm function: analysis and judgment and alarm when the thermal defect, sound abnormality, meter and oil level gauge are abnormal.

● Intelligent anti-drop: use 3D depth detection camera to automatically detect road conditions, choose anti-drop measures for bad road conditions.

● Intelligent anti-collision: multi-sensor fusion using laser radar, ultrasonic radar and soft anti-collision strip.

● Intelligent anti-theft: with independent anti-theft alarm function.

● Multi-service unit: HD imaging unit, infrared temperature measurement unit, UV detection unit, noise monitoring unit.

● Visual inspection: based on high-definition imaging unit for appearance detection of main transformer, high voltage reactance, oil pressure, circuit breaker, isolating switch, etc.

● Meter identification: Identify and judge the pointer area, oil level status, switch separation, meter text and indicator status of the meter, and upload the result to the local system.

● Automatic charging: support automatic return to automatic charging in the robot room.

● Self-test function: support the self-test function of the whole module, fault alarm prompt, upload fault information, locate faulty parts.

● Shortest path selection function: When receiving a special task, automatically select the shortest path to perform the inspection task.

● Intercom call function: the inspection system has duplex communication function.

● Inspection method: self-inspection and special inspection.

● Discharge detection: for the abnormal state of the line, instrument discharge arcing, using UV detection unit for detection (optional).


Application scenario

Power inspection robot can be used in high temperature, strong electromagnetic interference environment and severe weather such as heavy rain, strong wind and heavy snow. It can be loaded with infrared thermal imager, high-definition camera and other related substation equipment detection devices for automatic inspection and special inspection. The method of inspection, instead of patrolling the high-voltage equipment of the substation, detecting and identifying the internal meter and timely discovering internal thermal defects of the power equipment, external mechanical or electrical problems such as foreign objects, damage, heat, oil leakage, etc. The operator provides data on the diagnosis of accidents and failure precursors in the operation of electrical equipment.
