Old people falling alarm device

Abstract

The invention provides an old people falling alarm device. The old people falling alarm device comprises a CPU (Central Processing Unit), a three-axis acceleration sensor, a display module, a GPS (Global Positioning System) positioning module, Bluetooth modules, a buzzer, a pressure sensor, a microprocessor, an LED (Light Emitting Diode) lamp, a GSM (Global System for Mobile Communications) module and power supply modules; the old people falling alarm device is characterized in that at a watch end, one power supply module is used for supplying power to the CPU, and the display module and the GSM module are connected to an output end of the CPU; the three-axis acceleration sensor and the GPS positioning module are connected to an input end of the CPU, and one Bluetooth module is connected to a serial port end of the CPU; at a shoe end, another power supply module is used for supplying power to the microprocessor; the buzzer and the LED lamp are connected to an output end of the microprocessor, the pressure sensor is connected to an input end of the microprocessor, and another Bluetooth module is connected to a serial port end of the microprocessor. According to the old people falling alarm device provided by the invention, through the optimization of circuit design and the reasonable model selection of related assemblies / circuits / modules, the work of the whole old people falling alarm device is stable, information acquisition can be accurately carried out, the judgment is accurate, and the practicability is high.

Description

technical field [0001] The invention relates to the field of intelligent instruments, in particular to an intelligent device integrating fall alarm, one-key alarm, remote positioning and navigation functions. Background technique [0002] According to statistics, among the accidental injuries suffered by the elderly over 60 years old, the proportion of falls accounted for 40.60%. And now more and more elderly people are caught in a vicious cycle of "falling - losing confidence - not being able to move - being weak - more likely to fall". At the same time, it is not uncommon for these elderly people to get lost, fall and have no one to help them. [0003] Through research and analysis, we know that the corresponding fall alarm devices on the market are mainly in the form of a single device. The more mature ones are: fall alarm crutches and fall alarm belts. But we can also observe in ordinary life that most of the elderly do not use crutches, and at the same time, they do n...

Problems solved by technology

At the same time, after our continuous experiments, we found that if the watch is only used to judge the acceleration and angle or the pressure value of the foot to judge the fall, the false alarm rate is relatively high.
