CN203012926U - Intelligent sitting posture monitor - Google Patents

Abstract

The utility model discloses an intelligent sitting posture monitor, comprising a camera including a COMS image sensor, an ARM core microprocessor (MCU) and a peripheral circuit. The camera is connected with the ARM core microprocessor which is used to acquire the video image data of the camera in real time and locate the head posture of a user through a face identification algorithm, and the ARM core microprocessor is connected with the peripheral circuit including an alarm device and a power supply. According to the intelligent sitting posture monitor, the problems in the traditional sitting posture rectification apparatus that usage is inconvenient, uncomfortable, positioning is inaccurate, etc. are solved.

Description

The Intelligent sitting posture monitor

Technical field

The utility model belongs to the body-care articles for use, is specifically related to the sitting posture monitoring arrangement.

Background technology

Known correcting sitting posture and alarm set for the student is contact at present, must rely on certain position of user's health.For example, stent-type, cheap, but serious constraint user's lower jaw and cervical vertebra, long-time use can not feel well; Shading type need to be worn on head, and long-time use can not feel well; Adopt the pen type of infrared ray principle, if rely on pen holding posture and use other pens instead can not play supervision effect etc.

Summary of the invention

The purpose of this utility model is to provide a kind of Intelligent sitting posture monitor, to solve the use inconvenience that traditional sitting-posture correction device exists, and the technical matters such as uncomfortable, location is inaccurate.

In order to realize the foregoing invention purpose, the technical scheme that the utility model adopts is as follows:

A kind of Intelligent sitting posture monitor, the camera that it is comprised of the COMS imageing sensor and ARM core microprocessor (MCU) and peripheral circuit form; The vedio data of described camera and Real-time Collection camera, and connect by the ARM core microprocessor that face recognition algorithm is located user's head pose; The ARM core microprocessor is connected with comprising the peripheral circuit that warning device is connected with power supply.

The warning device of described peripheral circuit is to show face recognition algorithm and compare the LCDs of the pattern of display alarm simultaneously, power management message with the alarm threshold value of presetting.

The warning device of described peripheral circuit is to select alarm mode and alarm threshold value, and the button warning device of responsible sound or vibration alarming prompting.

Advantage of the present invention and good effect are miniature portables, can carry to be used in the study place such as family, classroom, library; Need not to wear, do not rely on health, without any constraint, alleviate student's health and psychological burden, long-time use can not cause dislike; Accurate positioning and use are flexibly.

Description of drawings

Fig. 1 is particular circuit configurations schematic diagram of the present utility model.

Embodiment

Particular circuit configurations of the present utility model is referring to Fig. 1, the monitor that it is comprised of COMS imageing sensor (camera) and ARM core microprocessor (MCU) and peripheral circuit.The vedio data of MCU Real-time Collection camera, and locate user's head pose by face recognition algorithm.When the head attitude reduces or after lateral excursion surpassed default threshold value, the Intelligent sitting posture monitor was sounded or vibration prompt immediately, the reminding user abnormal sitting posture is true, to reach pre-myopic-preventing purpose.The Intelligent sitting posture monitor is powered by poly-lithium battery, can show the residue service time of estimating.If the user is not within monitoring range, monitor is powered-down voluntarily, energy-saving and environmental protection.

In Fig. 1, COMS imageing sensor Real-time Collection vedio data, and by the IO port, vedio data is sent to the internal memory of ARM core microprocessor, pass through prior art, be that the complexion model algorithm is combined image binaryzation to collecting with the transposition histogram, obtain user's head pose.LCDs is used for showing the data after above-mentioned posture analysis and compares the information such as also display alarm pattern of while, power management with the alarm threshold value of presetting.Button and alarm module be in order to selecting alarm mode and alarm threshold value, and responsible sound or vibration alarming are reminded.Power management module provides power supply for other modules, accepts the Energy Saving Control of MCU, realizes the automatic or manual powered-down, bears simultaneously the battery charging management responsibility.
