1. System background
With the rapid development of the country’s economy, my country’s tunnel construction is changing with each passing day. Because urban tunnels, railway tunnels and highway tunnels have improved route technical indicators, shortened distances and travel time, and increased operating efficiency; coupled with the high cost of tunnels and relatively complicated operation and management, all regions attach great importance to the construction of tunnels.
The current remote information management system is often only the management of administrative and technical documents, and cannot obtain real-time construction information, let alone a comprehensive, timely and accurate grasp of the construction party’s information and construction personnel. This led to many accidents. For this reason, governments at all levels attach great importance to the safety of production in engineering construction and adopt a series of measures to continuously strengthen safety in production. How to change the current management mode of the backward safety management of the tunnel construction process and realize the modernization, informatization, and intelligence of management has become an important topic for managers.
Therefore, the use of advanced management methods such as disaster prevention, accident rescue, and electronic information technology is an inevitable choice for the safety management of tunnel construction. In response to the above situation, Suzhou New Electric Technology Co., Ltd. proposed a “Tunnel Personnel Attendance and Positioning System Solution” and provided a brand-new safety management concept for the safety management of tunnel construction.

Three, system introduction
Tunnel personnel attendance and positioning system is a combination of tunnel construction personnel attendance, regional positioning, safety early warning, post-disaster first aid, daily management and other functions. It is also a domestic technology-leading, stable operation, and professionally designed tunnel construction site monitoring system. Enable managers to keep track of the distribution status of personnel and equipment on the construction site and the movement trajectory of each personnel and equipment, facilitating more reasonable scheduling management. When an accident occurs, rescuers can also quickly understand the location of relevant personnel based on the data and graphics provided by the tunnel construction personnel and equipment location monitoring safety management system, and take corresponding rescue measures in time to improve the efficiency of emergency rescue work. The realization of this scientific and technological achievement will provide a strong guarantee for the safe production and daily management of tunnel construction to a new level. The schematic diagram is as follows:
Four, system characteristics
4.1 Excellent performance
★ High recognition reliability: 100% front-end recognition rate. As long as the construction personnel wear the 2.4G active radio frequency card correctly (unless it is broken), it can be read by a nearby card reader.
★ Long recognition distance (0-50 meters): It can reach a stable distance of 50M in the tunnel, and the information sent by the tag card within this range will be read.
★ Extremely high anti-collision: each detection point can simultaneously identify up to 50 construction personnel’s information.
★ High recognition stability (error rate is less than one hundred thousandths), truly achieve no errors and no missing cards.
★ Fast recognition speed: the fastest recognition speed can reach 200 km/h, even the dynamic tag card can be recognized.
4.2 Convenient and wide application
In line with the existing network conditions of the tunnel, it can provide multiple tunnel-to-tunnel transmission methods based on optical fiber, Ethernet, communication cable, etc., which are highly adaptable and do not require high on-site environment, avoiding implementation difficulties and problems caused by a single transmission method. bottleneck.
4.3 High safety and stability
★ It has safe explosion-proof, dustproof and waterproof performance
★ High anti-interference, no special requirements for tunnel interference source and surrounding environment, strong environmental adaptability
★ The internal circuit is highly integrated, the device failure rate is minimized, and the operation is reliable
★ Using active identification card, no electromagnetic pollution, maintenance-free, safe to use
4.4 Simple and convenient operation
★ The software has a full Chinese menu with a good operation interface
★ Integrated structure design of wireless monitoring sub-station, convenient and quick installation
★ The built-in battery of the identification card, ultra-low power consumption, no need for an external miner’s lamp power supply, no need to charge
★ The two-way card can replace the battery
4.5 Rich query and report functions
★ Query and report output, printing functions are simple and easy to operate
★ Inquire about the attendance information of construction personnel, departments and cadres
★ Various information reports can be output as required (such as: tunnel entry time report, personal attendance daily report, construction worker attendance monthly report, department attendance monthly report, etc.)
★ The real-time situation of the tunnel can be viewed remotely on any computer with Internet access, without the need to go to the scene. (Online version software function)
★ You can know at any time how many people there are in the cave, who are these people, and can be displayed on the LED display at the same time. The specific display content depends on the size of the display.
5. System function:
5.1 Attendance management function
★ Through the attendance base station, it can be judged that the construction personnel are the entry and exit records at any time.
★ Able to add, modify, and inquire about construction personnel, cadres and department information.
★ Employee Attendance Inquiry: The attendance status of personnel can be inquired by department and various specified conditions, such as: number, name, shift, type of work, department and other query conditions; it can be automatically sorted according to any conditions;
★ Cadre Attendance Inquiry: Query and display the attendance status of all cadres on the day;
★ Reports can be output according to user requirements
5.2 Positioning management function
★ You can inquire at any time and display the identity, quantity and distribution of personnel and equipment in a certain area.
★ Record a series of information such as the arrival/departure time and total working hours of relevant personnel and equipment at any location, and can supervise and confirm whether important inspection personnel (such as: safety inspection personnel) conduct on-site inspections on time and on-site, or conduct various inspections. The detection and processing of item data fundamentally eliminates related accidents caused by human factors.
5.3 Query Statistics
★Construction staff query: You can customize the combination of conditions to query the current area of the construction staff, the detention time and the leader of the shift into the tunnel.
★ Query of Worker Distribution: Query the distribution of construction personnel in each area of the tunnel, so that managers can easily know the number of workers in a specific area. Click on the corresponding area to get detailed information about the relevant personnel.
★ Statistics of construction personnel: The number of construction personnel entering and exiting the tunnel can be counted according to the date.
★ Regional population statistics: You can arbitrarily set and manage related construction areas, and automatically perform regional population statistics.
