Old people tumble alarm system based on biaxial sensor

Abstract

The invention discloses an old people tumble alarm system based on a biaxial sensor. The system comprises a gyroscope module, an accelerometer module, a signal processing module, a central control module, a wireless communication module and an intelligent terminal, wherein the gyroscope module and the accelerometer module are connected with the central control module through the signal processingmodule, and the central control module is connected with the intelligent terminal through the wireless communication module; the gyroscope module comprises a first sensor circuit and a second sensor circuit, the first sensor circuit and the second sensor circuit are connected with the signal processing module, the first sensor circuit is used for detecting standing angles on the front and back ofthe old people body, and the second sensor circuit is used for detecting a standing angle in the side direction of the old people. The provided old people tumble alarm system based on the biaxial sensor has the advantages that the device is small and exquisite, the carrying is convenient, a distress signal can be sent out to the intelligent terminal through wireless communication, and the system further has a real-time step counting function.

Description

technical field [0001] The invention belongs to the field of smart wristbands, and in particular relates to a fall alarm system for the elderly based on a biaxial sensor. Background technique [0002] Due to changes in social structure, population aging is a problem that countries have to face. According to statistics, 33% of the elderly over the age of 65 have fallen every year. The bones of the elderly are relatively loose, and a simple fall may cause serious consequences, making them unable to save themselves. Elderly people suffering from diseases such as coronary heart disease, cerebral infarction, and cerebral hemorrhage may fall into a coma. If the timing of rescue is delayed, the consequences will be disastrous. Contents of the invention [0003] The present invention proposes a fall alarm system for the elderly based on a biaxial sensor, which is characterized in that it includes a gyroscope module, an accelerometer module, a signal processing module, a central c...
