RFID attendance management plan for tunnel construction personnel
During the tunnel construction process, the usual method is to assign
full-time staff to stay at the tunnel entrance for flop registration or let the
people who enter and leave the tunnel to register by themselves. The traditional
management method has the inconvenience of changing personnel and listing
information, inaccurate group information, and it is difficult to record the
specific time of entering and exiting the tunnel.
In the construction of long-distance tunnels, especially during emergency
escape, it is necessary to have an accurate grasp of the information of the
people in the tunnel. In order to improve the risk management system for the
construction of long-distance tunnels, the registration and management of
personnel entering and exiting the tunnel in a more timely, detailed and
accurate manner.
Tunnel personnel safety management system integrates the functions of
tunnel construction personnel attendance, regional positioning, post-disaster
first aid, daily management and other functions. It is also a domestic
technology leader, stable operation, and professional design of tunnel
construction site personnel monitoring system. It enables management personnel
to grasp the distribution status of construction site personnel at any time,
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 personnel 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 tunnel personnel safety management system is based on the latest remote
electronic tag (RFID) identification technology. It uses a computer platform to
monitor the entrance and exit of the tunnel in real time, and uses radio
frequency technology to monitor the location of the identifiable electronic tag
(RFID) to achieve supervision in place. The system will automatically record the
relevant information of the current entry and exit, including name, position and
entry and exit time, so as to realize the automation, standardization and
diversified function management of personnel entry and exit tunnel information
management. Through the optical fiber network, real-time information about
people entering and exiting can be obtained at the tunnel entrance and remote
ground offices, which solves the shortcomings of traditional listing methods,
improves management efficiency and accuracy of information adoption, and ensures
real-time data.
2. Demand analysis
Real-time display/statistics of personnel information of each unit entering
and exiting the tunnel, and real-time display of personnel information in the
tunnel on the computer. Personnel information includes the person’s unit, name,
position, and location of the tunnel.
3. Scheme design
Personnel wear 2.4G tags, and 2.4G card readers are installed at each
monitoring point.
3-1 tunnel entrance and exit monitoring
Install 2~3 2.4G card readers at the entrance and exit of the tunnel
(recommended to install 3), each with a distance of 20 meters. When the operator
enters or leaves the tunnel, the system judges the direction of entry and exit
according to the order in which the card reader reads the card , And display the
current status on the management center computer in real time.
3-2 Personnel positioning in the tunnel
A 2.4G card reader is placed at a fixed distance in the tunnel. When a
person enters the area, the information of the person is captured by the card
reader, and the management center can know its location.
