A smart mine takes mine digitization and informatization as the prerequisite and foundation. It actively perceives, automatically analyzes, and rapidly processes mine production, occupational health and safety, technical support, and logistical support. The construction of a smart mine ultimately aims to achieve the building of a safe, unmanned, efficient, and clean mine. The construction of a smart mine mainly includes the building of a smart production system, a smart occupational health and safety system, and a smart technical support and logistical support system

Currently, coal production mainly takes place underground, characterized by relatively narrow working areas, poor lighting conditions, high temperatures, humidity, and high dust concentrations. High gas concentrations and high concentrations of corrosive and harmful gases exist in varying degrees in different mines. Meanwhile, coal mine production operations often involve a lot of heavy equipment. The transportation, installation, and debugging coordination among equipment require a high level of precision. Multiple types of work are carried out in a combined flow operation, and often require coordinated work both above and below the ground. Therefore, a safe, reliable, and multi – mode communication system can provide timely and reliable communication for personnel both above and below the ground, report potential safety hazards, and provide important guarantees for evacuation and rescue. Through efficient production dispatching communication, the efficiency of safe production is improved.

Based on this, the operation of this solution plays a crucial role in the safe production of the entire mine. Real – time monitoring can detect faults as early as possible, handle them in a timely manner, and effectively ensure the safe production of the mine. It provides a complete set of asset and personnel tracking and positioning solutions for coal mining enterprises.

1. It should meet the industrial – grade characteristics of mine integrated monitoring system products with low power consumption.
2. An industrial ring network should be formed above and below the ground to provide a broadband communication data platform and ensure reliable link transmission.
3. It should have electromagnetic compatibility characteristics superior to the industrial Class 4 standard, and be treated for dust – proof, moisture – proof, and corrosion – proof.
4. It should have good temperature characteristics and be able to work in an environment of – 40~85℃ for a long time.
5. It should meet the flexible power supply methods for mines above and below the ground. An industrial – grade isolated power supply should be adopted to increase reliability.
6. It should have a complete network management SNMP (Simple Network Management Protocol) and a user – friendly WEB interface.

Smart lamp posts are deployed along municipal roads, with built – in access switches. They are connected to various data collection devices downward and to aggregation switches upward. The aggregation switches are connected to the urban wide – area network nearby, and the data is collected to the data center through the urban wide – area network.

Levin Link’s industrial – grade switches have been applied in smart lamp post projects in many medium – sized and large cities around the world due to their high performance and reliability.
