ZigBee tags in tunnel personnel location applications

Program overview

Along with the rapid development of the national economy, the infrastructure is becoming more and more mature, and a variety of construction sites increasingly need to strengthen the personnel and equipment to carry out statistical andlocalizationThe uncertainty and randomness of the construction site greatly increase the difficulty of statistics and positioning, and the traditional statistical methods can no longer meet the current needs.

The construction site attendance and location system utilizes a provenRFID technologyThe system combines network and software technologies to form a complete attendance and positioning system, providing complete means and reliable tools for construction site management, supervision, search and rescue and other activities.

System Introduction

WorldTech Tunnel Personnel Positioning System withZigBee 2.4G technology, fast card reading speed of 200 cards / second, card reading distance of 5 meters to 80 meters adjustable, no card leakage. Provide managers with real-time statistics of personnel in the positioning area, attendance of people and vehicles, real-time statistics on the LED screen, access control to open the door, area alarm, swipe card to take pictures, first aid after a disaster, daily management and other functions. It can help the management to find and improve the weak links and prevent the occurrence of construction safety accidents.

positioning purpose

1、Reduce manual attendance workload and improve employee attendance;

2、Real-time display of personnel dynamic information to realize personnel dynamic management;

3. Ensure the safety of construction personnel and construction progress;

4. Restrictions on the entry and exit of personnel and the duration of their stay in special areas to achieve security management.

Tunnel personnel positioning system function introduction

1、Precise positioning of people in tunnel cavities

Adopting advanced 2.4G technology, it has the ability to locate the accurate number of cards without missing cards.

The strength of the signal from the tag to the reading device is used to calculate the distance between the device and the card through the RSSI value.

2. Positioning of personnel in hazardous areas of tunnels

The positioning base station is installed on top of the second liner cart and waterproofing cart, the personnel passes through the second liner cart into the waterproofing cart or the excavation cart, the positioning base station can accurately count and display the number of personnel and personnel location information.

3. Map showing the distribution of people in the tunnel

The map displays the location of the installed base station, the current distribution of construction personnel, and the map displays the alarm information and operation status of the equipment.

4、Automatic attendance of construction personnel entering and leaving the tunnel

Positioning base station combined with cave attendance equipment, the software automatically generates all kinds of reports, providing users with convenient daily management. It also provides the number of days of attendance of construction personnel; and the statistics of the number of people arriving at the site of each shift and each type of work. EXECL form can be exported.

5、Support a variety of data query function

Data can be queried based on a variety of conditions (e.g., personnel name, time, construction unit, type of work), time in and out of key areas, current number of construction personnel, total number of personnel on site, etc.

6、Control center gives evacuation orders to the tunnel

The control center can give evacuation information to the construction workers in the tunnel, and the construction workers will withdraw from the tunnel after receiving the alarm evacuation signal on their locator cards.
