The basic functions realized in the management of coal mine staff include:
1. Real-time display and query of underground conditions through Wi-FiRTLS personnel information:
How many people are in the well or in a certain place at any one time, and who are these people;
The activity track of each person at any time in the underground;
Query the actual location of one or more personnel, so that the personnel can be found quickly and accurately in an emergency;
Inquire about a series of information such as the arrival/departure time and total working hours of relevant personnel at any location, and can supervise and confirm whether important inspection personnel (such as: gas detection personnel, temperature detection personnel, exhaust personnel, etc.) are on time and arriving Carry out various data testing and processing, and fundamentally eliminate related accidents caused by human factors;
Multi-point sharing can be realized for multiple leaders to view at different locations at the same time.
2. The real-time dynamic distribution of underground personnel in the tunnel at all times, and the corresponding dynamic map is made according to the actual geographical situation of the underground, so that the underground situation is vivid and vivid at a glance;
3. In the event of various accidents, accurately and quickly identify the specific location and location of the person in distress, and can immediately find out how many people are in distress, who are they?
The functions implemented in device management include:
1. Real-time tracking and positioning of assets on or down the well, and effective management.
2. Increase the utilization rate of assets.
3. Prevent misplacement or loss of assets and reduce unnecessary search time.
An Introduction:
Program features:
Based on the original wireless local area network: no need to re-build other networks or facilities, the installation is convenient and simple, and the cost is greatly reduced.
Wide range: It can realize the recognition and tracking within the wireless coverage area, and accurately find the location of the object or person.
Extremely high anti-collision performance: It adopts multiple anti-collision schemes, which can identify hundreds of signs at the same time.
High-speed movement: supports the reading of high-speed moving objects or personnel data.
Two-way data exchange: Two-way high-speed data exchange can be realized between the electronic label and the visual software platform.
High reliability: Working temperature is -30℃~75℃, waterproof and dustproof, it can work normally for 24 hours in harsh environment.
Ultra-low power consumption: 3.6VLithiumCR123 replaceable battery, life can reach more than 5 years, and it is safe to human body without radiation damage.
The working principle of the system:
First, lay the wireless LAN in the coal mine production base, and place an electronic tag on the miner’s lamp worn by each worker. When the worker enters the mine, the wireless AP can immediately sense the signal of the electronic tag and upload it to the control center. On the computer, the computer can immediately determine the specific information (such as: who, where, and the specific time), and at the same time display it on the large screen of the control center or the computer display and make a backup. The administrator can also follow Click the distribution diagram on the big screen or on the computer to click on a certain position in the well, and the computer will count the personnel in this area and display it. At the same time, the computer in the control center will sort out various attendance reports (such as attendance rate, total attendance time, late/early leaving records, non-attendance time, etc.) of each underground worker during this period according to the personnel entry and exit information for a period of time. In addition, once an accident occurs underground, the location of the accident and the location of the person can be found immediately according to the personnel distribution information in the computer, so as to help rescuers rescue the trapped persons in an accurate and rapid manner. The management principles of mine carts and other assets are roughly the same.
System Components:
Electronic label, visualization software platform and wireless local area network AP.
electronic label:
In coal mining enterprises, electronic tags are mainly used in the monitoring and tracking of underground personnel and assets. At present, electronic tags used in coal mining enterprises mainly include personnel tags and asset tags. Personnel tags can be installed on safety helmets, and underground workers must wear safety helmets equipped with electronic tags. Through the WIFI real-time positioning system, the underground workers can be tracked in real time, and their status and specific location can be known at any time.
Visualization software platform:
Integrating the existing software of the enterprise, through a graphical operation interface, it can quickly detect and find the target object on the map showing the distribution of assets or the movement of personnel, and the operation is clear and simple.
Wireless LAN AP:
Based on the company’s original wireless LAN, equipment vendors include: Cisco, DLink, Netgear, Huawei, etc.
System design principles:
Realize the effective identification of the entry and exit of the working surface of the underground tunnel, so that the system management fully reflects the “humanization, information and high automation”;
Provide senior management personnel with information inquiries on attendance operations, personnel entry and exit restrictions, etc.;
Once a safety accident occurs, the system can immediately know the number of workers on the tunnel working surface to ensure the efficient operation of rescue and rescue work;
After a safety accident occurs, this system can accurately detect the presence of people within 3 meters of the accident site, facilitating the timely deployment of rescue work;
The system design is safe, expandable, easy to maintain and easy to operate.
In view of the actual situation of the mine, we have solved the technical problems of the application of the system products in the mine:
The problem of the safe operation of the equipment itself in the underground: In view of the special environment and working characteristics of the underground, our equipment achieves: adopts an all-metal shell, a firm structure, anti-collision and anti-vibration. Fully sealed design, waterproof, moisture-proof and anti-corrosion;
The operation of the equipment must not affect the safety of the underground: the equipment has ultra-low power consumption, and the peak power is less than 1 milliwatt;
The equipment adapts to various installation environment problems both above and below the mine: the equipment has a very high degree of anti-interference and basically has no requirements on the installation site, which guarantees the high reliability of the equipment operation and greatly simplifies the installation and maintenance workload;
The whole system is designed to be “fool type”, with extremely low technical requirements for users, with simple and adjustable functions, automatic fault inspection functions, etc.;
Simple construction and installation problems in the tunnel: The product adopts the direct wall-mounted type in the underground, and it can be connected to the DC power supply and the network cable connector. It is also very convenient and easy to change and add the underground detection points in the future;
Simplification of fault handling: When a machine fails, it can be directly replaced with a spare machine.
