What is the mine safety monitoring and early warning system, what kind of problems does it solve?

The mine safety monitoring and early warning system controls the three aspects of "unsafe behavior of people", "unsafe state of things" and "unsafe factors of the environment" in the coal mine, and when the monitoring of personnel not wearing safety helmets, smoking, mine cars falling off the road, personnel intrusion in the maintenance area, smoke and flames, illegal carrying of mine trucks, overfilling of coal piles, and pushing carts in the same direction, the alarm is immediately triggered, and the hidden dangers of accidents are found in time, so as to realize early warning of risks, and effectively protect the personal safety of coal miners from the source of coal mine accident risk.

1. Data collection is mainly used to monitor methane concentration, dust concentration, oxygen, carbon monoxide, carbon dioxide, sulfur dioxide, nitrogen dioxide, hydrogen sulfide, temperature and humidity, smoke, wind speed, air volume, damper opening and closing, equipment start and stop, gas extraction, liquid level, pressure and other parameters in the mine, so as to realize over-limit sound and light alarm, feed power outage, etc.

2. For data transmission, RS485 communication mode is used between substation and sensor and actuator, and photoelectric transmission mode is adopted between substation and switch.

3. Data storage, which is convenient for users to carry out data statistical analysis, scientific scheduling and disaster analysis.

4. Holographic and specific display functions, support large screen or multi-screen display.

5. Control function, judge according to the monitoring data, and control the status of underground equipment.

6. Super self-test function, the system can self-check equipment, software, data transmission, etc. and give fault alarms.

7. The system is integrated and linked, combined with other mining systems, to achieve underground safety monitoring, and provide data support for scientific production.

Characteristics of monitoring and early warning system: Modular design: According to the different business needs of users, the corresponding functional modules can be generated.

Parametric design: The system can not only monitor safety-related data such as gas, wind speed, start-stop, power outage, power feed, etc. It can also monitor various analog quantities, switching quantities, control quantities, adjustment quantities, gauge quantities and cumulative quantities in the underground in real time.

Multi-polar permission management: Set corresponding permissions according to the different responsibilities of provinces, cities, counties, mines, and system administrators.

Data processing: centralized data storage, various forms of data backup, log backup of important data, support dynamic compression storage, and regular processing. The disconnected data is retransmitted.

Data display: lists, curves, reports, etc.

Data interface: Adopt a unified and standardized data communication protocol, and the network connection follows the principle that the subordinate user obeys the superior user and the superior user provides the data format and transmission technology. Real-time data transmission.

Based on the open-source Web GIS, a supervision map is built, which displays the status information of each mine in layers and categories, and views the detailed real-time data of each mine.

The system stores the spatial information of the graphics in the form of points, lines and surfaces of the graphic elements, so that the graphics can be arbitrarily enlarged, reduced, roamed and printed out at any scale without distortion, and can intuitively carry out information query and various spatial analysis and decision support on the map. Real-time monitoring data for working condition information such as ventilation system, fan, damper status and monitoring system can be prominently displayed at the actual location of the mining engineering drawing; For all kinds of inspector information, it can be directly marked on various operation points, and the rectification situation can be seen at a glance.

Easy to operate and low maintenance of the system.

The system uses a browser page to replace the usual complicated professional application operation interface, making the operation interface extremely simple and easy to use, and the user does not need to install the application software system, which greatly reduces the maintenance cost of the system.

Convenient network monitoring capabilities.

After obtaining security authentication and permission, the system can be accessed at any node of the network to achieve real-time monitoring, network supervision and information query.

1.The alarm accuracy is high.

2.Real-time identification of alarms.

Based on intelligent analysis and deep learning neural network technology, real-time identification and early warning of personnel intrusion in the dangerous monitoring area, the alarm information can be displayed in the monitoring client interface, and the alarm information can also be pushed to the mobile terminal.

3.All-weather operation, stable and reliable.

4.Alarm storage function.

Coal mine safety risk monitoring and early warning system mainly includes:

1.Safety monitoring system: methane, carbon monoxide, wind speed, dust, temperature and other sensor settings, overrun alarm value setting, methane, carbon monoxide and other concentration curves, abnormal alarms, coal mine emergency response to early warning information (cause analysis, lifting), etc.

2.Personnel location monitoring system: the number of people going down, the mine leader leading the team to go down the mine, etc., whether the quota is exceeded and other abnormal conditions; Coal mines' emergency response to early warning information (cause analysis, lifting) and other situations.

3.Mine earthquake and in-situ stress monitoring system: mine earthquake, in-situ stress, energy, overrun alarm, analysis of whether there is abnormal situation; Coal mines' emergency response to early warning information (cause analysis, lifting) and other situations.

4.Hydrological monitoring system: early warning information such as coal mine drainage, water level, water temperature, etc., and emergency response (cause analysis and lifting) of early warning information in coal mines.

5.Mining equipment management system: important equipment safety signs, testing and inspection, annual maintenance plan, equipment operation status, etc., and emergency response (cause analysis and release) of early warning information in coal mines.

6.Dual prevention management system: risk identification, risk management and control, hidden danger investigation and management, daily upload of data information, emergency response (cause analysis and lifting) of early warning information in coal mines, etc.

7.Industrial monitoring system: system operation, camera nodes, image transmission, etc., check for violations such as blocking cameras, adjusting the position or angle of cameras without authorization, and stopping production and construction of coal mines.
