The unmanned track haulage system for underground mines



Underground mine driverless electric locomotive system is based on mature wireless communication WIFI, 4G\5G technology to build a reliable and stable wireless communication network at the transport level. It uses advanced technologies such as automatic control, video AI, precise positioning, big data and artificial intelligence combined with intelligent dispatching and dispatching models to achieve fully automatic operation of the underground electric locomotive or manual remote intervention in the loading process. The system fully responds to the national policy of "mechanisation for human replacement and automation for human reduction", promotes the evolution and change of the production management mode of underground mines, and lays the foundation for the realisation of smart mines, green mines and unmanned mines.

System composition.

The driverless electric locomotive system consists of an automatic operation (ATO) control system, a PLC control unit, a precision positioning unit, an intelligent dispensing unit, a wireless communication network unit, switch signal centralized closing control unit, a video monitoring and video AI system, and a control centre.

Brief description of function.

Fully automatic cruising operation: according to the theory of fixed speed cruising, according to the actual situation and requirements at each point of the transport level, the vehicle cruising model is constructed to realise the locomotive's autonomous adjustment of the travelling speed.

Precise positioning system: precise positioning of the locomotive is achieved by means of communication technology and beacon recognition technology, etc., with automatic bow lifting and autonomous speed adjustment.

Intelligent dispatching: Through the collection of data such as material level and grade of each chute, and then according to the real-time position and operating status of each locomotive, the locomotive is automatically assigned to work.

Remote manual loading: Remote manual loading can be achieved at the surface by controlling the loading equipment. (Optional fully automatic loading system)

Obstacle detection and safety protection: By adding a high-precision radar device in front of the vehicle to achieve the detection of people, vehicles and falling rocks in front of the vehicle, to ensure the safe distance of the vehicle, the vehicle autonomously complete a number of operations such as sounding the horn and braking.

Production statistics function: The system automatically performs statistical analysis of locomotive running parameters, running trajectories, command logs and production completion to form production running reports.

System highlights.
