On construction sites, workers wearing safety helmets and reflective vests shuttle under tower cranes and steel bars every day, working hard while also facing multiple safety hazards such as falling objects from high places, slips and injuries, and entering the area by mistake.

How to achieve precise supervision and safety warning of construction personnel without interfering with the construction rhythm? The answer is——Beidou high-precision positioning work card.

1、 Tailored "intelligent work signs" for construction sites

This is not an ordinary work card, but a "smart work card" that integrates technologies such as Beidou satellite positioning, UWB indoor positioning, RTK high-precision calculation, identity recognition, and real-time alarm.

Wearing it, the construction personnel will be able to:

• Real time recording of entry and exit time, automatic generation of attendance reports;

• Accurately monitor its dynamics in dangerous areas and automatically sound an alarm when it crosses the boundary;

• Immediately trigger a help prompt after falling, and synchronize pop-up reminders in the background.
  

2、 Key functional applications in construction scenarios

1. Real name registration+automatic attendance

Each work card is embedded with a unique ID, and workers do not need to clock in after wearing it. It automatically signs in when entering the construction site and signs out when leaving. The backend data is synchronized, and there is no need for manual attendance.

Advantage:

• Prevent proxy check-in;

• There is no dispute over salary and attendance;

• Compliance of safety management.

2. Automatic reminder of area crossing

Virtual fences can be set up for high-risk areas such as temporary danger zones, tower crane lifting zones, and edge openings. Once a worker accidentally enters, a work card will be issuedVibration+voice promptAt the same time, a red pop-up alarm will appear in the background to ensure prompt intervention.

3. Falling alarm for high-altitude operations

Falling from heights is one of the biggest hazards on construction sites. The work card is equipped with an acceleration sensing device. Once an abnormal change in gravity acceleration is detected, the system will automatically identify it as a "fall event" and push location information to the safety officer's mobile app.

4. Real time trajectory+off-duty management

The commanding personnel can open the map interface at any time to view the information of any workerHistorical trajectory, current status, and locationSupport thermal analysis of personnel distribution by team, job type, and region.

Once key personnel are found to have exceeded their departure time, automatic reminders and logs can be recorded.

3、 Introduction to backend system functions

• Importing electronic maps (supported by CAD/BIM)

• Positioning hierarchical display (by floor, area)

• Construction logs and alarm records can be exported

• Can be integrated with smart construction site platforms and public security real name systems

4、 Feedback on actual application effects

In a national key construction site project in Jiangsu, after deploying the Beidou high-precision positioning work card system, in just two months:

• The incidence of workers mistakenly entering high-risk areas has decreased by 70%;

• The average response time for falls on construction sites has been shortened to 45 seconds;

• The efficiency of manual attendance verification in the project department has been doubled;

• Construction data is more transparent, and Party A's acceptance is smoother.

5、 Besides safety, it can also facilitate daily life

It is worth mentioning that the work card also supports:

• Cafeteria consumption check-in

• Dormitory access control recognition

• Night security card verification

A work card that solves multiple scenarios is the "universal card" on construction sites.

6. Conclusion

The new management concept given to the construction industry by the Beidou high-precision positioning work card is "when people are present, they get stuck; when people move, they move. It is not about increasing regulatory burden, but using technology to reduce accident risks and intelligent assistance to improve construction efficiency.

In the future, as more projects move towards digitalization, BIM modeling, smart cities and other systems, the Beidou high-precision positioning work card will become the responsibility of every workerEssential digital ID cardTo safeguard their safety, rights, and work efficiency.
