Tunnel corridor subway construction personnel precise positioning system manufacturer customized attendance positioning management system
The tunnel safety comprehensive monitoring system uses advanced RFID + uwb networking technology to achieve precise positioning of personnel cards with a positioning accuracy of up to 0.33m. The system has a wide coverage area. A single base station can achieve 1 kilometer signal coverage, and can support cascading of Infinitus base stations to adapt to various tunnel shape layout requirements. The system integrates functions such as personnel attendance, emergency evacuation, SOS emergency help, real-time monitoring, trajectory tracking, trajectory playback, etc., and has the advantages of "low cost and high efficiency".
The precise positioning system for tunnel corridor subway construction workers consists of a host, a switch, a card reader, an energizer, and a tag card. The tag card is bound to personnel information and periodically sends radio frequency signals. At the same time, the card reader cooperates with the exciter to automatically identify the radio frequency signal and read the corresponding information, and transmits it to the database. The application interface displays the distribution of personnel outside the cave, inside the cave, and on the tunnel face in real time. situation and share the data to the LED large screen display.
System functions
1. The tunnel-specific personnel management system can real-time locate the location, time, movement route and other relevant information of personnel, vehicles, and special machinery in the tunnel area. 2. This system can be applied to various construction tunnels, high gas tunnels, urban pipe profiles, especially tunnels, pipe corridors and other areas with explosion-proof requirements.
3. Conduct real-time attendance and management of people and vehicles entering the positioning area. It can automatically, dynamically and accurately count the regional distribution of personnel in the tunnel area, providing a basis for normal production scheduling and accident rescue.
4. Statistics of personnel attendance, construction personnel, vehicle routes, and real-time locations can be used to instantly understand the flow of various technical work types.
5. Understand the current number and distribution of construction workers, and instantly query the area where any designated person is currently or at a designated time.
6. Query the activity track of any designated person in any time period.
·System advantages
·Multi-functional: Realizes important safety management functions such as personnel, vehicles, special real-time positioning, tracking and positioning, auxiliary attendance, trajectory query, and uniqueness detection in the tunnel. High capacity: The card reading speed is 200 cards/second, the card reading accuracy is ≥99%, and there is no missed card. Comprehensive monitoring can be achieved: The system automatically recognizes the identification cards carried by employees and supports automatic uploading of data, which can achieve comprehensive monitoring of personnel and facilities in the tunnel at a lower cost.
Green and environmentally friendly: The identification card issues a globally unique ID number. The radio frequency field power of the substation is much smaller than that of a mobile phone, and there is no electromagnetic pollution to the surrounding environment.
Multiple technology integration: The system integrates wireless data transmission, RS-485 bus transmission, low-power microcomputer technology, online programming and multi-level software technology.
Strong versatility: Provides a professional attendance module interface, and cooperates with the labor and management department to achieve real data attendance for all personnel.
Good guarantee: Realize dual-machine hot backup, effectively avoiding system problems caused by various faults during construction.
Self-diagnosis: The system has a self-diagnosis function. If a fault occurs, it can quickly display and alarm, and can quickly repair some faults that occur.
Strong expansion functions: practical functions such as authenticity monitoring, management, printing, storage, and human-computer dialogue.
