Integrated Solution for Personnel Positioning of Coal Mining
10cm high-precision positioning, core modules such as explosion-proof positioning base stations, positioning tags and engine softwares, build a precise positioning system ecology for coal mining workers.

Solution background:







 

Solution overview:


  EHIGH personnel positioning system of coal mining, drawing on UWB positioning technology, obtains accurate position of coal mining workers in real time through deploying certain positioning base stations in mine, and labelling workers with positioning tags, with accuracy reaching 10cm.

  The system integrates wellhead uniqueness detection device to carry out card-free detection, multi-card detection and substitute card detection. It can track the real-time position of coal mining workers and vehicles, getting a full grasp of their motion trails. Moreover, with electronic fence, the personnel positioning system of coal mining is able to realize both regional population statistics and dangerous area control. Meanwhile, it can link gas sensor, dust sensor and other sensors for environmental monitoring, and issue two-way alarm in case of emergency to improve the accident response rate. Its intelligent inspection function enables appraisal management of personnel inspection work, standardizing the inspection procedure. 


Case videos:

       With the increasingly higher requirements of China for safe production in coal mines, the upgrading and transformation of “Six Major Systems” of mine has been proposed. Meanwhile, the coal mining personnel positioning system also faces an upgrade from regional positioning to precise positioning.

Docking solution of integrated hardware:

| 3D real-time position display

Video linkage

Overview mode:

◆ Cast an overview to the position of workers at different heights, quiackly and visually grasp the situation of the site.

People at different heights are marked in different colors. 

◆ Maps of different heights are displayed in a rough figure in the overview to clearly distinguish the map location.

layering display:

◆ The map at each layer can be viewed independently, and information such as personal name, planning area and the tag list are presented on the page.

Support tag retrieval, issuance of paging and evacuation area delimitation. 

轨迹回放

◆ Long-term storage of personnel motion trails provides the basis for decision-making in tackling incidents.

◆ The motion trails of a person/vehicle within a specified period of time can be played back according to the card number or the specific area.

Combine the needs of user industry to set electronic fence, and define each part of the electronic fence area in the map.

Provide various rule types, including entry only/ deny-entry only/ leaving only/ deny-leaving only/ timeout in the area / immobile in the area / disappearing in the area/ gathering alarms.

| Dynamic electronic fence

◆ Hazard source setting: bind a specific card as the hazard source card, and an alarm will be issued when other positioning cards approach (the range can be set). Meanwhile, the card close to the hazard source will also issue an alarm promptly.

◆ Accompany setting: there must be an accompanying person (with accompany card) within the certain area oaround the person being accompanied (with accompanied card). There can be more than one accompanying person, and as long as any one of them are within the range, the system will not issue an alarm. Otherwise, the system will issue an alarm.

◆ Group-leaving alarm: if the distance between any two people (with positioning tag card) in a group exceeds the set value, the system will automatically issue an alarm.

| Video linkage

Select a tag for video linkage, the footage of this camera will be presented. 

◆ If the tag enters the area covered by another camera, the system will automatically switch to another camera.
