Three-way ultrasonic sitting posture correction chair based on single chip

Abstract

The invention discloses a three-way ultrasonic sitting posture correction chair based on a single chip. The three-way ultrasonic sitting posture correction chair comprises a chair body, three ultrasonic detection modules arranged on the back of the chair body, an infrared pyroelectric sensor, a single chip module, an A / D conversion module and an alarm module, wherein three ultrasonic detection modules are arranged on the back of the chair body respectively; the ultrasonic detection modules are arranged sequentially up and down; the ultrasonic detection modules are connected with the A / D conversion module respectively; the infrared pyroelectric sensor is connected with the A / D conversion module. According to the three-way ultrasonic sitting posture correction chair disclosed by the invention, through simultaneous detection of the three ultrasonic detection modules and analysis and judgment based on the information data returned simultaneously by the three ultrasonic detection modules, the sitting posture of a person is judged; the design greatly reduces the measurement error to a certain extent; moreover, by analyzing the information detected by the three ultrasonic detection modules through an algorithm, the sitting posture of the person can be judged more accurately, and a phenomenon of hunching is avoided better.

Description

technical field [0001] The invention relates to the technical field of correction chairs, in particular to a single-chip microcomputer-based three-way ultrasonic posture correction chair. Background technique [0002] With the advancement of science and technology and the development of society, more and more students have a series of unhealthy problems such as myopia and hunchback due to incorrect sitting posture and lack of exercise in the process of class and study, which has caused serious damage to the health of young people. It is a great disadvantage, and the traditional sitting posture correction chair is designed to detect the sitting posture according to the distance between the back of the human body and the chair, which can roughly calculate the sitting posture of the human body. Since the traditional detection generally only uses an ultrasonic sensor to complete the detection, it cannot be used for teenagers. Carry out a comprehensive test on the back, the error...
