UWB bracelet
Technical Field
The utility model relates to a wireless location technology field, concretely relates to UWB bracelet.
Background
Ultra wide band UWB location is a novel wireless communication technology, mainly comprises UWB location label, UWB location basic station, software control system triplex, and its basic operating principle does: the UWB positioning tag firstly transmits an ultra-wideband signal, then the UWB positioning base station receives the ultra-wideband signal, transmits the received signal to the software control system through a network cable or WIFI, and finally the software control system analyzes and positions the signal. The UWB positioning is insensitive to channel fading (such as multipath, non-line-of-sight and other channels), has strong anti-interference capability, does not generate interference on other equipment in the same environment, and has strong penetrability, thereby having high positioning accuracy and positioning precision.
With the gradual entering of China into the aging society, the aged old people are more and more, the physical functions of the aged old people are gradually degraded along with the increase of the age, and the aged old people usually suffer from some senile diseases, so that the special people often need to pay close attention and care to children or professional caregivers, but most of the old people cannot get corresponding attention and care due to the fact that the children are busy in work or the children cannot bear the professional care cost. When some old friends get on the street alone, when getting lost or causing sudden diseases or discomfort due to physical reasons, if the old friends do not use communication tools such as mobile phones, the old friends only passively wait for pedestrians to rescue the old friends, and even if the old friends can skillfully operate the mobile phones and make rescue calls correctly, the old friends often have the situation that the rescue personnel cannot arrive at the correct rescue place in the fastest time due to the fact that specific position information of the old friends cannot be clearly and accurately described, and therefore the best rescue time is missed or the rescue efficiency is reduced.
