The construction site personnel positioning system is an integral part of the on-site construction personnel safety management system, which effectively strengthens the effective management of construction personnel, reduces the accident rate of construction personnel, and is widely used in construction scenarios with certain risks such as tunnel construction, subway construction, and pipe gallery construction.

In response to the demand for effective personnel management in various construction scenarios, Hangzhou Tengdong Information Technology Co., Ltd. has developed a positioning system for various construction site personnel using Bluetooth positioning technology. The system can accurately locate construction site personnel in real time, ensure personnel or area safety, and manage the location of materials and equipment on site, facilitating timely allocation and attendance management when needed, improving construction management level, and providing reliable data basis for accident handling and rescue work, ensuring efficient operation of emergency rescue and disaster relief work.

1Some problems faced by construction site management:

1 Management of commuting for construction personnel

Regarding the attendance of construction personnel, such as when they arrive at work, when they leave, and various fraudulent issues, the traditional approach is to use attendance machines. This only solves the problem of head and tail, and cannot effectively monitor the existence of personnel

2 Workload management of construction personnel

The efficiency of construction personnel is closely related to the efficiency of the project. Efficiency management of construction personnel has always been a difficult problem in project management. Attendance of personnel does not mean that they are in a working state. How to improve the work efficiency of personnel, reward advanced and combat backward, in addition to effective incentives in management processes, it is also necessary to use technological means for auxiliary management

3 Management of Visitor Personnel

The safety of construction sites is also reflected in the management of visitor personnel. Visitor personnel are not familiar with the situation of the construction site, so it is extremely easy to encounter danger. It is difficult for the construction site to always follow the visitors. Therefore, it is very important to introduce location management for visitors and provide effective guidance

4 Safety management of construction personnel

The focus of site personnel positioning is to increase safety measures for construction personnel. Safety measures are not sufficient through management processes. Firstly, personnel are prone to a decrease in safety awareness during long-term work. Secondly, the work on the site is relatively tight, and people are prone to fatigue, increasing the probability of errors; In addition, security issues are zero tolerance, so it is necessary to effectively avoid them through technical means

5 Big Data Analytics

How to obtain basic data is a prerequisite for further big data analysis of construction sites, improving efficiency and safety in various aspects

2、 Function Implementation of Construction Site Personnel Positioning System

1. Real time positioning of personnel and visitors

By deploying a construction site personnel positioning system, it is possible to view the real-time location, on duty time, and off duty time of on-site construction personnel in real time. The software can display the real-time positions of different types of personnel within the positioning area in three views: flat, three-dimensional, and list, making it convenient for management personnel to understand the real-time status of personnel in a timely manner. It can also count the number of personnel by region and floor, achieving efficient management.

2Management and tracking of construction equipment and tools

The objects located by the construction site personnel positioning system include personnel, vehicles, engineering equipment, and various tools. In addition to ensuring the safe operation of employees, it also has the function of protecting valuable materials and dangerous goods.

It can accurately locate the location of mobile devices and materials, facilitating efficient management of materials and improving the efficiency of calling mobile devices.

3Playback of Object Movement Trajectory

The construction site personnel positioning system will automatically save the movement trajectory of personnel, and managers can view the movement trajectory of personnel and equipment at any time by name or card number, which is convenient for personnel control and historical event analysis; By analyzing the movement trajectory of construction personnel, the on-site situation can be reconstructed, providing intuitive and visual information support for various types of behavior analysis and data analysis.

The duration of saving motion trajectory data (how many days of data will be automatically saved) can be customized according to customer needs.

4Electronic fence safety warning

Electronic fences are set up at the entrances and exits of the management area through the construction site personnel positioning system. When construction personnel or certain specific equipment approach the boundary of the electronic fence, the system automatically triggers sound and light alarms, thereby improving the safety index. At the same time, the central control room (management software) will also sound an alarm to remind management personnel.

The specific fence area can be set according to the actual situation on site, and can be square, circular, polygonal, and so on.

5In case of danger, one click for help

Once a disaster or other abnormal situation occurs, the management personnel can click on the evacuation button on the monitoring background interface of the construction site personnel positioning system and select the evacuation area. The personnel in that area will immediately receive the evacuation command and be prompted to evacuate through sound and light alarms.

At the same time, construction personnel can issue an alarm by pressing the "one click alarm" button on the positioning tag they carry, notifying management personnel to control and provide real-time emergency rescue in a timely manner.

6.Construction personnel behavior testing

Through the construction site personnel positioning system, real-time monitoring of abnormal behaviors such as personnel disappearance, gathering, timeout, and disappearance can be achieved. If any abnormalities are detected, an immediate alarm can be issued to improve the management of personnel safety.

7.Video linkage

The construction site personnel positioning system supports access to existing video surveillance systems, integrating existing camera devices into the management monitoring system, fully utilizing the functions of the video surveillance system, and reducing overall system costs. The management monitoring system can display the video footage of each camera in real time, and management personnel can view the video footage of each camera at any time through the management monitoring system to confirm the on-site situation.

The construction site personnel positioning system can achieve video linkage based on various alarm situations, that is, when an emergency situation occurs, such as strangers appearing at entrances and exits, personnel entering unauthorized areas, personnel approaching dangerous sources, personnel seeking help, etc. If there is video surveillance at the location of the emergency, the monitoring camera will promptly link to the software management end to pop up real-time on-site video images for display and take photos to record the on-site situation for future reference.

8.Emergency situation positioning

Once an unexpected situation occurs, the corresponding personnel's location can also be found in a timely manner through the management backend. At the same time, visitors to the construction site can be located and managed to view their positions and movement trajectories, in order to prevent danger.

9.Assessment of personnel working hours

The construction site personnel positioning system accurately locates the location of personnel, effectively calculates the working time of personnel in the target area, compares and analyzes the working time of construction site personnel, and facilitates subsequent work assessment

9.Construction site access control and attendance system

By installing entrances and exits for personnel commuting to and from the construction siteLEDThe access control system that displays functional information collects and manages the identity information of all incoming and outgoing personnel. including:

（1）Set up a work area for each employee to effectively prevent safety management in the work area;

（2）Record employees' commuting time and movement trajectory during work hours;

（3）Determine whether there is any off-duty during the work period;

（4）Statistics department, personal attendance reports and charts, etc.

At present, ensuring the safety of construction personnel in tunnels, subways, and large outdoor construction sites has always been a key and difficult point. The establishment of a site personnel positioning system can significantly improve management efficiency and is of great significance for ensuring construction safety.
