An important issue in on-site construction management is construction safety, which ranks first among various issues. Improving site safety management, strictly controlling the entry of irrelevant personnel to the site, and ensuring that the personnel leaving the site promptly, safely, and normally exit the site are an important part of the construction and production safety management.
With the gradual maturity of RFID technology, RFID construction personnel management systems are increasingly being used in practice in construction projects. Especially in the project implementation site with a wide range of construction sites and harsh on-site environment, in order to conduct safety and standard management of the construction site, the personnel management system based on RFID technology is applied to the construction project, which can monitor the personnel status of each construction site in real time and manage it in a unified manner. Effectively improve the management efficiency of project construction.
The comprehensive management system for construction site personnel developed by Shenyang Kaitai Technology based on RFID, sensors and other technologies is widely used in practical applications
By sticking or wearing RFID electronic tags on the front of the construction workers’ helmets, the identification and entry and exit management of the workers in the operation area of the construction site can be realized. With the on-site LED display, real-time on-site personnel information.
RFID electronic label selection:
Considering that all identification points need to accurately record the entry and exit of personnel, tri-frequency RFID electronic tags are used, and the appearance of the tags should be considered for easy sticking in the helmet.
System networking:
Analysis of door personnel entry and exit application mode:
The entry and exit of the gate personnel of the construction site is usually controlled by swiping the three-roller gate. After using the RFID automatic identification electronic tag, the three-roller gate is controlled according to whether it is necessary or not. There are two application modes, and the corresponding equipment is different.
Mode 1: Automatic reading, no control of three roller gates
This mode is the same as the identification of people entering and exiting at the entrance of the building. A calibration reader is installed inside and outside the three-roller gate, connected to the communication gateway, and automatically judges the entry and exit.
Three channels, using 4 calibration readers.
Mode 2: Automatically read and control three roller gates
In this mode, an RFID calibration reader for vehicles needs to be installed in each channel of the three-roll gate, connected to the access controller, and control the three-roll gate.
Three channels, using 6 calibration readers, with 3 double-door controllers.
Software platform logical structure
System functions:
1. Personnel access statistics management.
2. Non-card holders enter and exit sound and light alarm.
3. Automatically capture images of people entering and leaving.
4. Real-time broadcast access statistics and videos.
5. Personnel regional positioning.
Real-time monitoring of personnel
