UWB Real Time Location Tracking in Tunnel
With full implementation of projects, it offers an accurate and feasible location solution for the construction of subways, railways, tunnels, etc.

Pain Points of the Industry:









Solution Overview: 

 

 With UWB technology, EHIGH tunnel location tracking system deploys location anchors on the service trucks, platform trolleys and lining trolleys, and equips construction workers with location tags. The system can carry out 1D & 2D location for workers, vehicles and any construction machinery (excavators, loaders, etc.) with the accuracy up to 10cm.

 The tunnel location tracking system supports round-the-clock attendance checking, real-time automatic tracking of construction workers, non-card detection with cameras, so that it can also comprehensively grasp the trajectory and position distribution of construction workers in the tunnel. Besides, it can give two-way alarms in case of emergencies. Most importantly, it can immediately locate any trapped workers in case of a sudden accident in the tunnel. Therefore, the safety of workers are ensured and the efficiency of management can be improved.  


  ◆ Difficultly in guaranteeing personal safety

  ◆ Blind rescue in the wake of accidents

◆ The inefficiency of traditional management

◆ Difficulty in investigating the cause of accidents

Major Functions:

| Storage and playback of historic tracks

Electronic fence for tunnel personnel positioning

◆ Attendance checking: automatically record the construction workers' time of arrival and departure from the entrance.

◆ Working-hour counting: calculate the working hours for individuals or departments for each time slot.

◆ Information identification: automatically identify the tag holder's ID number, name, team, position, phone number and other information.

◆ Data export: retrieve and print attendance information based on personal information, and generate attendance reports.

◆ Track storage: unlimited storage of motion trails can provide the basis for decision-making in tackling incidents.


SOS alarm of tunnel personnel positioning

| Real-time location

隧道人员定位之实时定位

◆ Overall coverage of the supported area and construction area in the tunnel.

◆ Real-time location, distribution and trails of construction workers / vehicles.

◆ Smooth and stable location service without signal drift.

| Attendance checking and working-hour counting

隧道人员定位之智能考勤

| Paging and evacuation alarms

Paging and evacuation of tunnel personnel under positioning

◆ Paging alarm: the system can send paging alarms and dispatch construction workers properly.

◆ Evacuation alarm: in case of any ermergency, the system can issue evacuation orders to the construction workers based on the specific area.

| Active and passive SOS alarm

◆ The construction workers can send SOS message to the system by simply pushing a button on their location tags, then a real-time alarm is sent.

 

| Electronic fence

◆ The shape, alarm rules and access rights of the electronic fence are subject to flexible adjustments.

◆ Alarm will be issued if any personnel trespasses dangerous areas to ensure the safety of construction workers in the designated area.

| Non-card detection

Non card detection of tunnel personnel positioning

◆ When the construction workers or other unathorized persons enter the tunnel without the tag, the system will send a big sound-light alarm.

 

◆ If the construction workers are ill at ease (in a coma, etc.), their tag will automatically send an alarm to the system to have timely rescue.
◆ Track playback: the movement track of a person / vehicle within a specified period of time can be played back based on the specific person or area.
◆ Combined with the video surveillance system, the system can capture and record non-tag workers, effectively prevent unathorized persons from entering the tunnel.
