1. System background
With the rapid development of the country’s economy, my country’s tunnel construction is changing with each passing day. As urban subways, railway tunnels, and highway tunnels have improved route technical indicators, shortened distances and travel time, and increased operational efficiency, the country is constantly increasing the construction of tunnels; however, the construction cost of tunnels is high and the operation management is relatively complicated. Therefore, all places attach great importance to the construction of tunnels and dare not take it lightly.
The current remote information management system is often only the management of administrative and technical documents, and cannot obtain construction information in real time, let alone a comprehensive, timely and accurate grasp of the information of the construction site and construction personnel, which leads 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 lagging management mode of safety supervision during tunnel construction and realize the modernization, informatization, and intelligence of management has become an important topic for managers to study.
Therefore, advanced management methods such as disaster prevention, accident rescue, and information management will be an inevitable choice for the safe construction of tunnels. Shenzhen Wanquan Intelligent Technology Co., Ltd. puts forward the “solution of the tunnel construction personnel statistics system” in response to the above situation, which provides a brand-new safety management concept and strong guarantee for the safe construction of the tunnel.
2. System function requirements:
It is required to implement long-distance RFID automatic identification statistics for tunnel construction personnel and vehicles entering and exiting, and to query the information of people entering and exiting the tunnel, vehicles, and people stranded in the tunnel based on the recorded data according to time, name, team and other conditions
Data can be permanently saved through computer software, and statistical reports can be issued
The conditions of construction workers in the tunnel can be monitored online through software
An external high-brightness LED display can be connected to display the name, job number, entry time and other information of the current construction personnel in the tunnel
3. System introduction
The tunnel construction personnel statistics system integrates real-time statistics of tunnel construction personnel, work attendance, safety early warning, post-disaster first aid, daily management and other functions. It is also a domestic tunnel construction site monitoring system with leading technology, stable operation and professional design. It enables management personnel to grasp the distribution status of personnel and equipment on the construction site and the movement trajectory of each personnel and equipment at any time, facilitating more reasonable scheduling management and safety monitoring management. When an accident occurs, rescuers can quickly understand the location of the relevant personnel based on the data provided by the system, and take corresponding rescue measures in time to improve the efficiency of emergency rescue work. The realization of this scientific and technological achievement has promoted the safe production and daily management of tunnel construction to a new level.
Chapter 2 System Design
2.1 System composition
The tunnel personnel management system is divided into the outside of the tunnel, the inside of the tunnel, the personnel and the transmission part:

2.2 Working principle
2.4G active radio frequency card: carried by construction personnel or workers, usually installed on the belt or helmet of the construction personnel. When managing the vehicle, stick the active radio frequency card on the upper right corner of the windshield of the car. Vehicle recognition can be set to pressure-sensitive card reading mode, or can be set to a free mode of reading when there is a card, both of which can perform statistics on vehicle entry and exit.
