Bathroom fall-down alarm method and device based on UWB technology

Abstract

The invention provides a bathroom fall-down alarm device based on a UWB technology. The bathroom fall-down alarm device comprises a plurality of UWB base stations, wearable equipment, a first single chip microcomputer, a first NB-IOT device, an alarm device and a mobile terminal, wherein the UWB base stations are arranged in a bathroom, the first single chip microcomputer, the first NB-IOT deviceand the alarm device are arranged outside the bathroom, the wearable equipment is worn by a user, the UWB base stations are connected with an input end of the first single chip microcomputer, an output end of the first single chip microcomputer is connected with an input end of the first NB-IOT device and the alarm device, an output end of the first NB-IOT device is connected with the mobile terminal, a UWB tag is installed on the wearable equipment, the UWB base stations receive information transmitted by means of the UWB tag to perform real-time position monitoring on the user, the UWB basestations transmit a fall-down signal to the first single chip microcomputer when monitoring that longitudinal position information of the user changes suddenly, the first single chip microcomputer receives the fall-down signal and transmits the fall-down signal to the alarm device and the first NB-IOT device simultaneously, the alarm device is activated to transmit an alarm signal, and the first NB-IOT device receives the fall-down signal and transmits the fall-down signal to the mobile terminal.

Description

Technical field [0001] The invention relates to the technical field of alarm devices, and in particular to a method and device for alarming bathroom falls based on UWB technology. Background technique [0002] The bathroom environment is humid and it is easy for people to slip and fall, especially the elderly or people with mobility impairments, if they are injured after a fall, causing inconvenience, or knocking their heads to cause fainting, etc., they cannot send a distress signal by themselves; Most households use gas water heaters. Gas water heaters are easy to leak during use, which can easily cause carbon monoxide poisoning and cause users to faint and become unconscious; some users may cause insufficient brain oxygen supply due to overheating of bath water and long bathing time Sudden fainting; in these three cases, no self-rescue behavior can be produced after a fall. Therefore, a device that can automatically recognize the user's fall behavior and issue a corresponding ...

Problems solved by technology

[0002] The bathroom environment is damp and easy to cause people to slip and fall, especially the elderly or people with disabilities. If they are injured after falling, causing inconvenient movement, or knocking on the head and causing fainting, etc., they will not be able to send out a distress signal by themselves; there are still Most households use gas water heaters. Gas water heaters are prone to leaks during use, which can easily cause carbon monoxide poisoning and lead to users fainting and unconsciousness; some users may have insufficient oxygen supply to the brain due to overheated bath water and too long bath time And suddenly fainted; these three situations can not produce self-rescue behavior after falling, so a device that can automatically recognize the user's fall behavior and send a corresponding alarm message is needed
