1. Basic concepts
During tunnel operation, it can automatically identify the reading equipment pre-installed in the mine, and upload the globally unique card number of the identification card to the ground computer system, so that the manager can grasp the movement track of the person at any time to facilitate reasonable scheduling management .
2. Scheme design
The tunnel personnel management system involves computer software, database, electronic circuit, digital communication, wireless identification technology, etc. Therefore, in addition to its functions, the stability, reliability, anti-interference ability, fault tolerance and abnormal protection are also fully considered when designing the scheme. The project plan determines to use the existing mature Ethernet plus fieldbus system as the main transmission platform, develop corresponding sensors, personnel wireless identification cards and other equipment and system connection, through the sensor and special software for attendance management and the main system with a standard special database Perform background data exchange so as to realize the tracking and positioning of operators and safety management. The overall design of the system is mainly reflected in:
Realize the effective identification and monitoring of the entry and exit of tunnel operators, so that the management system fully reflects “humanization, information and high automation”, and realizes the goal of digital tunnel personnel management.
Provide tunnel management personnel with various management information such as personnel entry and exit restrictions, attendance operations, monitoring and monitoring, etc. Once a safety accident occurs, through special handheld devices, the work surface can be immediately detected within 10-30 meters of the accident site with a card to work The personnel and their numbers ensure the efficient operation of emergency rescue and safety rescue work.
The system design is safe, expandable, easy to maintain and easy to operate.
Easy networking, BS structure, easy to realize network monitoring of counties, cities, provinces and a wider area.
3. System principle
The personnel management system of Shanghai Xiupai Tunnel is supported by the main computer of the ground monitoring center under the support of the system software, through the data transmission interface and the communication light/cable laid along the roadway, regularly conducts data inspection and information collection on the installed wireless data sensors. The data sensor will automatically collect the information of the identification card within the effective recognition distance, and according to the system instructions, transmit the relevant data to the ground center station through the transmission network. After the data information is analyzed and processed, the dynamic distribution of personnel (or moving targets such as locomotives) can be reflected in the main computer interface in real time, so as to realize the purpose of digital management of the safety status on the well.
Following the principle of “unified card issuance, unified equipment, and unified management”, the identification card is regarded as an “entry permit” or “tunnel access permit”, and the “one person, one card” system is implemented according to the permitted personnel.
According to mine monitoring requirements, wireless data sensors with access direction and time recognition capabilities are installed in tunnels, work surfaces and other locations, and they are connected to each other as high-speed industrial Ethernet through optical fiber data transmission interfaces to form a complete communication line.
After the tunnel production unit enters the relevant information of the staff, it will issue and equip the identification card to the tunnel staff.
The system database records the basic information of the person corresponding to the identification card, including basic information such as name, age, gender, team, type of work, position, photo, and validity period.
Workers entering the tunnel must carry the identification card with them. When the cardholder passes through the location where the identification system is set up, the system will recognize the card number. The system will read the card number information and transmit the cardholder’s road section, time and other information through the system transmission network. It is transmitted to the ground monitoring center for data management, and prompt information can appear on the large geographic information screen at the same time, showing the name of the passing personnel. If the detected wireless identification 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.
The production unit can authorize the management of the identification card according to the production plan. The scope of authorization includes: tunnels or work surfaces that the employee can enter. In order to prevent irrelevant and illegal persons from entering the tunnel or work surface, the system is equipped with a time management module for access to the tunnel or work surface of the card, as well as card failure and loss reporting.
Once a safety accident occurs in the tunnel, the monitoring center can know the basic situation of the trapped person in the first time. The rescue team uses a mobile remote identification device to easily detect the location of the person in distress within a range of 10-30 meters, which is convenient for rescue. The safe and efficient operation of work facilitates the development of accident rescue work.
The system can automatically generate report data on the statistics and management of attendance operations to improve management efficiency.
Four, system function
Real-time personnel dynamic display
Query and display the number, distribution and identity of a certain place at any time.
Query the current actual location and activity track of one or more personnel.
Record a series of information such as the arrival/departure time and total working hours of relevant personnel at any location, which can supervise and implement whether important inspectors conduct on-site inspections on time and at the point, or conduct various data detection and processing, fundamentally Try to avoid related accidents caused by human factors.
Abundant personnel tunnel attendance functions
It can perform statistics on personnel entering and exiting the well, realizing the attendance records of tunnel personnel, creating and printing various information reports (such as tunnel time report, attendance monthly report, overtime report, absence report, etc.) of personnel entering and exiting the well, so as to facilitate the query of management personnel And management.
Multi-point sharing of information
The central station of the system and the network terminal can be networked in a local area network, so that all terminals on the network can share information at multiple points within the scope of use authority, so that multiple mine departments and leaders can share monitoring information, system comprehensive analysis information, and query information at different locations at the same time. Class data report.
Restricted zone alarm function
For the designated restricted area, if an unauthorized person enters, a real-time sound alarm will be issued, and the number and identity of the person entering the restricted area will be displayed.
Post-disaster first aid information
In the event of various accidents, the upper computer can immediately display the number of people carrying the card, personnel information, and personnel location at the accident site, which greatly improves rescue efficiency and rescue effectiveness.
Sensor emergency function
When the sensor loses contact with the ground central station, it can still work independently and automatically store personnel monitoring data.
Identification of tunnel personnel and one-to-one correspondence function
Shanghai Xiupai’s personnel location detection and attendance system has special interface functions, which can perform rapid, group sending, rapid identification and one-to-one correspondence of the identity of tunnel personnel to ensure that the management is in place.
