Alarm device and method based on GPS/Beidou satellite

Abstract

The invention designs an alarm device and method based on GPS / Beidou satellite positioning special for old people. The invention relates to the techniques of satellite positioning, acceleration measurement and heart rate measurement. Along with the increase of old people living alone, the old people cannot call for help in time due to sudden diseases or accidents, and more and more conditions where save and treatment are delayed are generated. An existing GPS / Beidou positioning device usually only has a positioning function, but a manual alarm function and an automatic alarm function which arespecially designed for the old people are innovatively added to the GPS / Beidou positioning device. Firstly, the old people can press down an alarm button to realize manual alarm. Secondly, an automatic alarm function is specially designed, and an alarm is given when the position exceeds a preset region based on position information, an alarm is given when the position does not change for a long time, and a drop alarm based on acceleration measurement and a heart rate abnormity alarm based on LED blood reflection are given. Heart rate records and movement tracks are also reported regularly foranalyzing and monitoring physical conditions. According to the device, information is wirelessly transmitted to a background server through NB-LoT.
