Application of ZigBee+GPS Positioning in Personnel and Asset Management in Mobile Scenarios

I. System Background

Logistics transportation and tour group travel share several key characteristics: first, a large number of assets/personnel are involved; second, they are mostly in a mobile state. This makes it difficult to achieve PTZ surveillance and historical trajectory tracing.
By utilizing West-HN Technology's ZigBee positioning GPS devices, this problem is easily solved. As long as tags are within approximately 50 meters of a mobile gateway, personnel can be counted in real-time. Inventory checks can instantly identify which team member/item has left a specific location, facilitating quick retrieval in the vicinity.

II. System Advantages

• Rapid Personnel Binding
  • Upon joining the tour, the tour leader distributes tags with basic tourist information. These are then quickly bound to the group via the APP software, streamlining subsequent statistical tracking and management.
• Real-time Query
  • The tour leader can perform real-time headcounts during the tour to immediately identify if any team members have fallen behind. If someone is missing, they can be located in the shortest possible time.
  • The mobile gateway reports GPS data and tag distance information to the cloud in real-time, enabling quick tracing of the last known location of a missing person/lost item. During cold chain transportation, movement trajectories and temperature status can also be reported in real-time.
• Tag Recycling & Reuse
  • After the tour concludes, the tour leader can collect the tags from team members, unbind the personnel information in the software system, and prepare them for the next binding application.

III. Solution

• Each person/item carries an electronic tag.
• The tour leader/transport vehicle carries a mobile portable device. Personnel/item information is entered into the system software and bound to the tags.
• The tour leader/backend can perform headcounts as needed to check if all personnel/items are present or if anyone/anything is missing.
• If the tour leader/backend cannot read a specific team member's/item's tag during a headcount, it indicates that person/item is beyond the 50-meter range of the gateway, triggering a trace and search.
• Geofencing can be set up to trigger alarms when the predefined area is exited.
