Embodiment Construction

[0012] Such as figure 1 As shown, the present invention is a fall sensor that can be used in a mobile phone. In addition to the mobile phone, it also includes the following modules: a data acquisition module, a control module, and a voltage conversion module. The connections of each module are as follows: figure 1 Shown.

[0013] The sensor circuit can detect the mobile phone's movement change state, and judge the state of the human body by detecting the acceleration of the mobile phone. The data acquisition module is composed of an acceleration sensor and its peripheral circuits. The acceleration sensor transmits the movement change of the mobile phone through the three-way signal output interface Xout, Yout and Zout are sent to the control module. The control module is composed of a single-chip microcomputer and its peripheral circuits. The single-chip microcomputer converts the three analog signals provided by the acceleration sensor in the data acquisition module through the a...

Abstract

The invention relates to a fall sensor circuit, in particular to a fall sensor circuit applied to a mobile phone. Its characteristic is that the analog data collected by the sensor is transmitted to the single-chip microcomputer, and the digital signal obtained by the single-chip microcomputer is monitored by the internal analog-to-digital conversion circuit. The transmitting circuit automatically sends predetermined distress information, and its device is composed of a data acquisition module, a control module and a voltage conversion module. The fall sensor circuit proposed by the present invention has simple hardware structure, fewer chips and low power consumption. The present invention is particularly suitable for the elderly, children, mentally handicapped people and patients who are prone to falls.

Description

Technical field [0001] The invention belongs to the field of fall sensors, and more specifically relates to a mobile phone to which the circuit can be applied. Background technique [0002] In modern society, there are many elderly people, children, people with intellectual disabilities, and patients who are prone to falls. However, due to various reasons, guardians cannot be with them at all times. If they are negligent, they often have serious consequences. However, the existing anti-fall proposals are generally independent devices, which are not only inconvenient to carry, but also difficult to intelligently judge whether the user has an accident. Especially when the user is far away from the crowd, the effect of the buzzer installed on the device is minimal. , Can not effectively send out distress messages. [0003] At present, with the rapid development of communication and information technology, mobile phones have been popularized to the greatest extent. However, when an ac...
