The remote integrated management network system of coal mine based on the Internet of things M2M
This system is an information management system that integrates computer network technology, automatic control technology, wireless data communication technology, database technology and related underground system technology. This system is composed of two independent subsystems, a real-time monitoring system for production safety and a county-level coal mine management information system. Its main function is to use the Internet of Things M2M wireless data public network to transmit the underground monitoring data of mine safety production to the safety monitoring management center at all levels through the substation (downhole) and the main station (uphole) to realize the safety production management at all levels. The center can simultaneously grasp the data of downhole safety production in the first time, understand the status of downhole safety production, timely and quickly implement remote command and dispatch and remote control, eliminate hidden accidents to the greatest extent and reduce the incidence of accidents.
For small coal mines managed by county-level governments, in addition to transmitting mine safety production data, the system can also transmit daily coal production, daily excavation progress, daily energy consumption, daily blasting chemicals consumption, number of people underground, and production to the management department as required. , Sales and equipment related information, thus forming an effective comprehensive information management for small coal mines.
The biggest feature of this system is that it embodies the real-time performance of data monitoring and the synchronization of data at all levels of monitoring centers. The safety production management agency thousands of miles away can extract the current safety data of a certain operation surface of a certain mine at any time, which is also the biggest difference from the wired transmission network in the past.

System Features
ใใThe wireless/mobile Internet of Things M2M wireless data public platform is used for communication networking, and the network construction is very fast, and it can be installed and used immediately, saving a lot of time and cost.
It can be seamlessly connected with the original underground and ground safety monitoring system, or only the original data communication method can be upgraded.
Breaking through time and space constraints, it is possible to establish a unified monitoring network across regions, provinces and even the whole country to realize real-time data sharing and centralized management.
Realize the data synchronization of all levels of data management sub-stations, master stations and monitoring centers in the first time, and truly achieve real-time online monitoring of the entire network.
It can realize the wireless remote transmission of multimedia data (image, audio), and further broaden the scope of monitoring objects.
Real-time data or voice communication can be carried out with moving targets (emergency vehicles, inspection vehicles, test vehicles, etc.).
System functions
The sensors and detectors (methane sensors, portable methane detection alarms, carbon monoxide, carbon dioxide monitors, etc.) that guarantee safe production in underground mines are subject to 24-hour uninterrupted automatic real-time online monitoring and monitoring.
Automatic real-time monitoring of the operation status of various motors and electrical equipment underground.
Various sensors can be inspected automatically at regular intervals, and fault alarms can be issued.
The current and historical values โโof safety instruments, various sensors, and concentrators can be viewed and extracted at any time
Automatically collect, store and send data from wellhead monitoring stations, downhole substations and concentrators in the Internet of Things M2M wireless manner. Ensure 100% data integrity.
Automatic calculation and analysis of data, and can automatically generate various types of curve charts and statistical reports.
The data critical value can be set remotely, and the data close to or reach the critical value can be automatically alarmed. For example, when the gas concentration threshold value is set, when the gas concentration reaches a dangerous value, the underground ventilation equipment will be forced to start automatically.
Automatically send mobile phone SMS notifications and reminders to safety production management personnel on a regular basis.
When equipped with a digital camera or camera, images or images can be transmitted by wire/wireless.
The data acquisition and transmission terminal can be remotely set, remotely diagnosed and remotely controlled.
This system can be connected to all types of online instruments or sensors, data concentrators, and can also be compatible with various types of databases. The user’s original front-end equipment access mode and wired transmission mode can be completely retained or used as a backup.
The system has powerful data processing functions and decision support functions, and is simple to operate, stable and reliable, and easy to use. It satisfies the management needs of information storage, data query, remote extraction and decision support to the greatest extent, and reserves sufficient expansion space for embedding more management modules in the future.

Main functions of county-level coal mine management information system
The county-level coal management department can supervise and check the safety production status of small coal mines through the system at any time.
The GIS electronic map function provided by the system can directly view the geographic location and related information of all small coal mines in the jurisdiction on the map. You can also see the automatic alarm information of small coal mines on the map.
Small coal mines regularly upload comprehensive corporate information to county-level coal management departments, such as daily coal mining volume, daily excavation progress, daily energy consumption, daily blasting chemical consumption, number of people underground, and production, sales, and equipment related information.
The management system software can automatically generate daily, monthly, annual, and related graphs of corporate information statistics.
The system automatically inspects underground safety equipment, electrical equipment, and ventilation equipment, and finds and eliminates faults in time.
The system automatically and regularly sends mobile phone SMS notifications and reminders to safety production managers. The system can also realize the SMS alarm function.
The system has authority management function, information confidentiality function and Internet access function.
The system is reliable, easy to operate, maintenance-free, and able to resist various interferences.
