Sitting posture reminding device based on Hall effect

Abstract

The invention discloses a sitting posture reminding device based on a Hall effect. The sitting posture reminding device comprises a clamping module, a reminding module, a sensing module, an anchoring module, a power supply module and a control module, the anchoring module adopts a rubidium magnet, is fixed on a pen cap of a user and is used for generating a magnetic field for induction of the induction module; the sensing module adopts a Hall element, is arranged on the clamping module and is used for sensing corresponding Hall electromotive force formed by the anchoring module; during work, the control module compares the Hall electromotive force sensed by the sensing module with a preset voltage threshold value, and when the Hall electromotive force sensed by the sensing module is larger than the preset voltage threshold value, the prompt module is controlled to work to remind a user to correct the sitting posture. Compared with a traditional sitting posture correcting instrument, the sitting posture correcting instrument is better in convenience and intelligence, higher in signal sensitivity and smaller in influence on the public environment, especially in public places such as schools.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a sitting posture reminding device based on the Hall effect. Background technique [0002] Most of the single-function products such as back support and forced support equipment are popular in the market at this stage. These products will make the human body feel uncomfortable after a period of use, so they are rejected by students. [0003] The latest domestic technology proposes a multifunctional sitting posture correction device based on a single-chip microcomputer. The purpose is to design a light and foldable flat-bed sitting posture correction device that can remind you to maintain the correct sitting posture at all times and can be heated when the room temperature is too low. The design mainly includes the minimum system of single chip microcomputer, temperature detection circuit, temperature heating circuit, ultrasonic detection circuit, pressure sensing circu...

[0004] However, this document does not carry out the actual production of a multi-functional sitting posture corrector based on a single-chip microcomputer. At present, it only describes the theoretical results of the design. How to install the desktop pressure detection circuit, whether it will cause inconvenience to the use of the table, and the actual application effect How no further exploration is made, only theoretical effects are described
