Explosion-proof ground track-type intelligent inspection robot wireless charging: improving the safety of unattended operation and maintenance in explosive environments
The explosion-proof ground track-type intelligent inspection robot combined with wireless charging technology is a key operation and maintenance equipment in explosive environments such as petrochemicals, coal mines, and gas. It uses a dedicated ground track to achieve precise mobile inspections to avoid the impact of ground obstacles, and uses non-contact wireless charging to ensure long-term unattended operation and improve intrinsic safety levels.
Application scenarios and demand background
This type of robot is mainly deployed in explosive areas on the ground, such as petrochemical plant storage tank areas, oil pipeline corridors, gas stations and coal mine ground belt corridors. These places have high concentrations of dust, gas or combustible gases, and manual inspections pose risks of explosions such as open flames and static electricity. The ground track design is adapted to complex terrain and supports slope climbing and obstacle avoidance.
Typical inspection tasks cover equipment status monitoring, leakage detection and environmental parameter collection to ensure production continuity and accident prevention.
System composition and core functions
The system consists of ground track, robot body, sensor array, control base station and wireless charging pile. The robot adopts an aluminum alloy or steel structure chassis, is equipped with an electronically controlled drive, and supports RFID+encoder positioning with an accuracy of ±10mm.
Key features include:
- Multi-modal perception: high-definition imaging, infrared thermal imaging, gas (CH4, CO, H2S) and smoke sensors to achieve intelligent identification of deviation, overheating and leakage.
- AI analysis and early warning: Built-in edge computing module performs real-time algorithm processing of images, vibrations, and acoustic signals to support fault prediction.
- Communication and control: 5G/WiFi transmission, supporting remote scheduling, video return and linkage alarms.
Advantages of wireless charging technology
The explosion-proof wireless charging pile adopts the principle of inductive coupling. The robot automatically aligns and transmits energy through the coil. There are no exposed contacts to avoid potential risks of sparks and wear. Powered by lithium iron phosphate batteries, it has a battery life of over 24 hours on a single charge, a charging efficiency of over 85%, and meets the Exd IIC T4 Gb explosion-proof standard.
Compared with contact charging, it reduces maintenance frequency and improves reliability, and is especially suitable for ground environments with serious dust accumulation.
Technical challenges and development trends
Challenges include track installation adaptability, electromagnetic compatibility and charging stability in high temperature and high humidity environments. In the future, digital twins and 5G-MEC will be integrated to realize inspection data cloud analysis and predictive maintenance, and promote the transformation of explosive sites from passive response to active prevention and control.
