The invention discloses a low-power-consumption personnel zone location method based on multi-sensor coordination. The method includes: setting a low-power-consumption boundary positioning device at zone boundary, and setting a low-power-consumption receiver in a zone; when the person passing the zone boundary is detected, allowing the low-power-consumption boundary positioning device to arouse a tag card carried by a located person, record an event that the tag card passes the zone boundary and transmits the event to a server; after the located person carrying the tag card enters the zone, keeping the tag card to be constantly and periodically communicated with the low-power-consumption receiver set in the zone; after the located person carrying the tag card leaves the zone, allowing periodic communication between the tag card and the low-power-consumption receiver to interrupt, and allowing the tag card to re-enter the low-power-consumption dormant state to await being aroused by low-power-consumption boundary positioning devices in other zones. The method achieves accurate low-power-consumption zone location for personnel, the problem that the existing zone location technology has large errors is solved, and cost of power consumption in location process can be lowered.
Description
Technical field [0001] The invention belongs to the field of wireless communication, and relates to a personnel area positioning method, in particular to a low power consumption personnel area positioning method based on multi-sensor coordination. Background technique [0002] Precise regional location information plays a very important role in many application scenarios, such as tourist guides in scenic spots, office personnel location tracking, etc. Users do not pay attention to specific location coordinates. Precise regional location information is more effective for such applications . In regional positioning technology, traditional distance-based positioning technology requires more infrastructure support. For example, infrared, acoustic wave, ultrasonic and other distance-based positioning algorithms rely on the deployment of infrastructure, and are limited in large-scale or basic conditions. It is difficult to apply and deploy in different application scenarios. The loca...
