Multi-network Multi-system Integrated Platform for Digital Mine

1. Design background

Safety monitoring systems, precise positioning systems, 4G communication systems, WiFi transmission systems, switch access systems and traffic light systems are important components of smart mines. At present, main problems are as follows.

 

Information island:systems are set up independently, so their data are separated, causing failure in data sharing, interconnection, intelligent analysis, and intelligent control.

Complex system construction:systems are set up independently, with a large number of base stations, power supplies and other devices. In addition, systems are routed separately, making the network complex, resulting in the problems of high complexity, repeated construction, and difficulty in maintenance.

High system cost:systems to be set up independently should be purchased, constructed, debugged and maintained separately, resulting high operation and maintenance costs at the late stage.

Complex wiring:systems are set up independently, resulting in repeated construction, repeated wiring, large construction quantities and high construction costs. The relocation of a working face involves the relocation of systems, which is troublesome.

Difficulty in maintenance:The independent construction of systems will lead to difficulties in subsequent maintenance, such as difficulties in troubleshooting, identification of faults due to decentralized equipment, technical support and coordination, etc.

Difficulty in upgrade:all devices need to be replaced for technological upgrades, including base stations and power supplies, which is equivalent to dismantling and reconstruction.

The construction of mine systems has developed from independent system construction to system integration. To solve the above problems, Yiri has developed a set of multi-network multi-system integrated platform to promote the development of intelligent mines.

 

2. Platform Introduction

By sorting out the current system construction status and problems and adopting the design principle of multi-network multi-system integration, system hardware and software are deeply integrated, including the precise positioning system, 4G communication system, WiFi transmission system, switch access system, traffic light system and intelligent transport vehicle management system, to reduce difficulties in system construction, use and maintenance, promote the interconnection of systems and improve the application values of systems.

In the multi-network multi-system integrated platform for digital mines, underground wired communication networks and wireless communication networks are connected to the underground ring network through the integrated substation, thereby simplifying the underground network and improving the network stability; the underground precise positioning, auxiliary transport vehicle management, auxiliary traffic light, safety monitoring, wireless communication (wifi/4G/5G), emergency broadcast and other systems are organically integrated for the unified access, loading and management; and devices and construction costs are reduced. In addition, the integrated platform features simple installation, use, maintenance, upgrade, etc.

3. Platform Advantages

Advanced

1) Systems can be connected and loaded in a unified manner based on the integrated substation.

2) Each subsystem is connected to the Ethernet ring network system, which is stable, reliable and flexible.

3) The integrated substation features the highly integrated, modular and plug-in structure, which is advanced in the market at present.

4) Positioning based on UWB/ZigBee TOF technology, with a positioning accuracy of less than 30cm/3m.

5) The 4G/WiFi communication technology (suitable for seamless upgrade to intrinsically safe 5G network) is used in the wireless communication system. The platform has the functions of VOLTE high-definition voice and video calls. In addition, wired and wireless systems on the ground and underground can be dispatched in a unified manner.

Easy to install and maintain

1) One device is suitable for multiple systems.

2) The number of devices to be maintained at the late stage is greatly reduced.

3) Modular and pluggable boards are conducive for quick replacement and upgrade.

4) Real-time monitoring by different types of network monitoring software (network management software and substation monitoring software) for stable operation.

High reliability

1) The integrated substation supports the self-cascading and access to the ring network.

2) The network structure is simple (fewer devices, optical cables and other cables), greatly reducing faults.

Scalability

1) Slots are reserved in the substation to support board expansion.

2) Software can be expanded for vehicle positioning management, intelligent vehicle dispatching management, etc.

High compatibility

1) The system is suitable for configuration of corresponding modules, integration of optical and electrical ports, and expansion for 485 ports, CAN ports, RJ11 ports, sensor ports, etc.
