Intelligent chest tag for nursing home based on UWB (Ultra Wideband)

Abstract

The invention discloses an intelligent chest tag for a nursing home based on UWB (Ultra Wideband). The chest tag comprises a shell body, a microphone, a loudspeaker, a display screen and a panic button which are arranged on the shell body, a microprocessor, a UWB ranging module, an alarm module, a power supply, an intercom module, a communication module and a health sensor which are arranged in the shell body, wherein the microphone and the loudspeaker are electrically connected with the intercom module, and the mutual conversion of a voice signal and an electrical signal is realized through the intercom module; the panic button is electrically connected with the alarm module, and an alarm signal generated by the alarm module is transmit to a microcontroller; the health sensor transmits the measured health data and the positioning information acquired by the UWB ranging module to the microcontroller and displays the information on the display screen; the power supply provides electricenergy; and the microcontroller and a monitoring terminal preform mutual data transmission through the communication module. The intelligent chest tag realizes accurate positioning, which is convenient for timely processing of emergency situations of users.

Description

technical field [0001] The invention relates to the technical field of intelligent communication equipment, in particular to a UWB-based intelligent badge for nursing homes. Background technique [0002] In nursing homes, the elderly may suffer from sudden illness or some suffer from Alzheimer's disease, etc. Nursing workers are often unable to accompany every elderly person 24 hours a day, and there will inevitably be omissions in work. How to protect the safety and health of the elderly in nursing homes has always been a problem that nursing homes must pay attention to and effectively solve. Since the elderly generally do not use smart phones, if an emergency occurs, the nursing home cannot handle it in time, which will bring great troubles . [0003] At present, some of the smart badges on the market have anti-lost functions, but the positioning function of these badges is mostly realized through the GPS positioning module. The positioning accuracy of GPS is low, and the...

How to protect the safety and health of the elderly in nursing homes has always been a problem that nursing homes must pay attention to and effectively solve. Since the elderly generally do not use smart phones, if an emergency occurs, the nursing home cannot handle it in time, which will bring great troubles

[0003] At present, some of the smart badges on the market have anti-lost functions, but the positioning function of these badges is mostly realized through the GPS positioning module. The positioning accuracy of GPS is low, and there are certain errors in positioning. It will cause obstacles when people work, and GPS positioning needs to rely on network nodes, which is easily restricted by the surrounding environment, and the signal is also easily interfered
