chrispeng [ad_1]
The basic functions realized by the above scheme in terms of underground personnel management include:
1. Real-time display and query of underground conditions based on ZigBee technology:
1. How many people are in the well or in a certain place at any one time, and who are these people?
2. The activity trajectory of each person at any time in the underground.
3. Query the current actual location of one or more personnel, so that the dispatch center can quickly and correctly contact the personnel.
4. Inquire about a series of information such as the arrival/departure time and total working time of relevant personnel at any location, so as to supervise and implement whether important inspectors conduct the test and processing of various data on time and at the point, and fundamentally eliminate it as much as possible Related accidents caused by human factors.
5. Multi-point sharing can be realized for multiple leaders to view at different places 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. The various reports of various types of personnel going down the well are automatically counted as follows:
1. The production personnel’s downtime report, attendance monthly report, overtime report, leave or absence report and other management required basis and can generate salary report, etc.
2. Develop and count management personnel’s inspection report and so on.
3. Whether other personnel, such as visitors and inspectors, go to the designated area as required.
4. Once various accidents occur, how many people are in distress can be found immediately, and where are the persons in distress? Who are they?
5. Use mobile identification devices during emergency rescue to more accurately and quickly identify the specific location and location of persons in distress, and improve rescue efficiency and rescue effectiveness.
The functions implemented in device management include:
1. The specific real-time location of the car and other important equipment
2. Calculate the number of daily transportation and the frequency of ingress and egress of each minecart, which is convenient for management.

2. The working principle of the system
First of all, place several signal transceivers in the various tunnels and the passages through which all personnel may pass. The specific number and location are determined according to the actual working conditions on site and the functional requirements to be realized. Their ZigBee autonomous network technology and the ground control center Computer networking.
At the same time, each downhole wears an identification card. When the downhole enters the well, as long as they pass or approach any signal transceiver placed in the tunnel, the signal transceiver will immediately sense the signal and upload it to the computer in 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. Click on the distribution diagram on the screen or on the computer to click on a certain position in the well, and the computer will count and display the personnel in this area. At the same time, the computer of the control center will sort out various attendance reports of each person who went down during this period (such as attendance rate, total attendance time, late/early leaving records, non-attendance time, etc.) according to the personnel entry and exit information for a period of time.
In addition, once an accident occurs underground, the personnel at the accident site can be found immediately based on the personnel distribution information in the computer, and then special detectors can be used to further determine the location of the personnel at the accident site to help rescuers rescue them in an accurate and rapid manner Trapped personnel. The management principles of mine carts and other equipment are roughly the same.
4. System design principles
(1) Realize the effective identification of the entry and exit of the staff in the underground tunnel work surface, so that the system management fully reflects the “humanization, information and high degree of automation”. It provides senior management personnel with information inquiries on attendance operations and personnel entry and exit restrictions. Once a safety accident occurs, the system can immediately know the number of workers on the tunnel working surface, ensuring the efficient operation of emergency rescue and safety rescue work.
(2) After a safety accident occurs, the mobile identification device of this system can detect the presence of people within 10 meters of the accident site, which is convenient for the timely deployment of rescue work.
(3) The safety, scalability, easy maintenance and easy operation of the system design.
5. System design features
(1) Highly automated. The system can automatically detect the time and location information of the underground tunnel workers passing the monitoring point, and automatically realize the statistics and management of attendance operations.
(2) Advanced communication system. The identification system installed in each channel of the underground mine transmits the data passed by relevant personnel to the network server in real time, without human intervention in the whole process.
(3) Complete data statistics and information query software. The system software has a dedicated database management system, including the information collection and statistical analysis system for workers passing through the tunnel, the statistical and management analysis system for attendance operations, display and print various statistical reports, and provide a full range of services for senior management inquiries and management .
(4) The safety, stability and reliability design of the system. The system products adopt the tunnel wall-mounted design, no need to carry out on-site construction in the tunnel, and ensure that the system operates continuously and normally for 24 hours in harsh environments;
(5) Complete alarm call system configuration for abnormal conditions (including ID card and invalid ID card entry).
6. System design
This system follows the principle of “uniform issuance of identification cards, unified equipment, and unified management”, and implements the system of “one person, one identification card” in accordance with the permission of staff and teams. Entry permit”. The specific plan is as follows:
(1) The mine production unit installs a certain number of signal transceivers in all tunnels, and the specific location is determined according to the site conditions to meet the radiation area.
(2) The mine production unit issues identification cards to relevant personnel.
(3) The basic information of the employee corresponding to the identification card, including name, age, gender, team, type of work, position, personal photo, etc., are logged in the system database.
(4) The identification card becomes effective after the safety production department authorizes it. The scope of authorization includes: the employee can be qualified to enter the tunnel on the work surface, the time limit, invalidity, and loss of the identification card, so as to prevent irrelevant and illegal persons from entering the tunnel;
(5) Personnel entering the tunnel must wear an identification card. When the person passes the identification monitoring point of the tunnel, he is immediately recognized by the system, and through the information exchange of the system network, the information such as the road section and time passed by the person is transmitted to the well safety monitoring center for record, and can be recorded on the large geographic information screen at the same time A prompt message appears on the wall, showing the name of the passing person. If the sensor ID card number is invalid or enters a restricted channel, the system will automatically alarm, and the security monitoring center staff on duty receives the alarm signal and immediately executes the relevant safety work management procedures.
(6) Once a safety accident occurs in the tunnel, the safety monitoring center can know the basic situation of the trapped person at the first time. The rescue team uses a mobile remote identification device to facilitate the detection of the location of the person in distress within a certain range and facilitate the rescue. Safe and efficient operation of work.
