(2) judge whether sitting posture standardizes:

As seat someone, detection judges the voltage value of Ua, Ub point voltage, we use the ratio of two electrical voltage points of Ua, Ub Value is calculated, if Ua/Ub=C；

1. as 0.5≤C≤2, we judge the stress of human buttock two sides be it is almost the same, judge sitting posture specification without Skew；

2. we judge that the stress of human buttock two sides is inconsistent as C > 2 or C < 0.5, there are crooked feelings in body Condition judges that sitting posture is lack of standardization；

(3) data storage function:

Related data information is stored by memory module 5, in the present embodiment, can be reserved at least 90 days sitting posture phases Pass data (learn duration daily, start over time, the study frequency etc.), allow parent to become more apparent upon the study condition of child.

(4) prompting function:

Voice reminder module 6 and vibration reminding module 7 can or learning time incorrect in child sitting gesture it is too long when, with language Sound or vibration mode make prompting, to allow children that can adjust oneself sitting posture and learning time in time, it is bad to correct children Sitting posture behavior, and children's fatigue study for a long time is avoided, in the present embodiment, after student successive learning 45min, voice reminder Module 6 issues a rest reminding every 1min, can be reminded three times.

(5) data transmission and sitting posture evaluate and test function:

The judgement result of MCU microprocessor 3 is transmitted on matched electronic mobile device APP by bluetooth module 8, is allowed Parent can more easily understand the phases such as the sitting posture state in children's study time started, end time and learning process Information is closed, can add up and record long-term learning data and sitting posture status data, in the present embodiment, Intelligent seat is able to record Virgin nearest 90 days sitting posture data, system can automatically generate the sitting posture report (3,7,30 days etc.) in a period of time, work as sitting posture When accuracy is lower than setting value, APP gives parent's prompting, can also nearest one week sitting posture report of automatic push.
