Coal mine integrated automation management and control platform is the application of automation technology, computer software technology and communication technology to the coal mine site to achieve comprehensive monitoring system; The system platform is based on the premise of "centralized storage application, distributed management, data unification and permission sharing". The overall structure of the system adopts hierarchical logic design and is divided into three layers from the bottom up: device layer, transmission layer, and information layer. Based on the flexible B/S and C/S interfaces, the coal mine is fully automated and intelligent in the production links of "mining, digging, transportation, wind, water and electricity", so that the production and management of the whole mine is more scientific and efficient; According to the hardware platform and network system, the software "Visual information system for integrated management of safety production" is used to build a unified software integration platform. Through the company LAN and the man-machine interface of the system, the information of engineering, production, safety and equipment operation status can be comprehensively queried, which provides an advanced information support platform for mine safety and production management.

At present, in the underground high-voltage power supply system of coal mine, the distance of the power supply line is short, and the short-circuit protection time of the off-line switch of the ground substation is small. If a short-circuit fault occurs, the multi-stage switch is often tripped at the same time, which leads to a large area of underground power outage and seriously affects the safety production of the mine.

The basic task of the comprehensive protection device of high and low voltage switch in coal mine power supply system is to automatically, quickly and selectively remove the faulty equipment or line from the power system, so that the faulty components will not be damaged, and ensure that other trouble-free parts will quickly return to normal operation. When the project system capacity is large and the wiring is complex, the protection configuration design and action coordination will be very difficult, and the protection selectivity and reliability problems are prominent. Therefore, it is necessary to carry out reasonable configuration, analysis and calculation of the integrated protection device and setting value of the power system. Moreover, with the increase of the system capacity and the adjustment of the system load, the setting value of the integrated protection device of the system needs regular accounting and maintenance. In order to ensure that the requirements of the actual working conditions are met.

The visual access control device for mining is a set of access control equipment with functions such as swipe card, video surveillance and voice intercom, which is used for access management; It is mainly installed in the substation room or pump station room in the coal mine, and is used as the central substation, the mining area substation, the temporary power supply point, the fire material warehouse or the water pump room, the access control and the door status monitoring. The access control device mainly includes mining access control controller, mining casting type electromagnet, intrinsic safety power supply, ID/IC induction card, industrial computer, control management software and card issuer. The access control controller installed in the mine communicates with the computer host on the ground through optical fiber Ethernet. In normal operation, only the underground part can be formed into the access control device. The computer host on the ground is only needed when remote control and real-time status monitoring are required. It can realize the functions of remote call door opening, local IC card door opening, face recognition door opening, iris recognition door opening, fingerprint recognition door opening, etc., which is an important product for realizing unattended coal mine automation.
