Detailed description of the invention
It is described more fully with example embodiment referring now to accompanying drawing.But, example embodiment can
Implement in a variety of forms, and be not understood as limited to embodiment set forth herein；On the contrary, it is provided that this
A little embodiments make the present invention more comprehensively and completely, and the design of example embodiment are passed on all sidedly
To those skilled in the art.Reference identical in figure represents same or similar structure, thus will
Omit repetition thereof.
The word expressing position and direction described in present invention, is all saying of carrying out as a example by accompanying drawing
Bright, but can also make a change as required, done change is all contained in scope.
Refer to Fig. 1, it illustrates the structural representation of the pressure test device 2 of the embodiment of the present invention,
This pressure test device 2 includes multiple pressure transducer 3, A/D change-over circuit 4, microprocessor 5 with
And the prompting module 6 electrically connected with microprocessor 5.The number of pressure transducer 3 can be 4N,
Wherein N is the positive integer more than 1.In the embodiment shown in fig. 1, N is 2, and the most totally 8 pressure pass
Sensor.
All adjacent pressure transducers 3 are arranged into annular successively.In the present embodiment, 8 pressure sensings
Device 3 is arranged into annular, and is distributed uniformly and circumferentially." annular " of the present invention is also not specific to
Circle, can be multiple concrete shape.
A/D change-over circuit 4 electrically connects with pressure transducer 3, as it is shown in figure 1, each pressure transducer
3 all individually electrically connect with A/D change-over circuit 4.A/D change-over circuit 4 receives from each pressure transducer
The reflection analogue signal of local pressure size and convert thereof into digital data transmission to microprocessor 5.
Microprocessor 5 electrically connects with A/D change-over circuit 4.Microprocessor 5 receives A/D change-over circuit 4
Digital signal after, use travel through each pressure transducer mode carry out computing, it is judged that pressure gap situation.
When pressure gap reaches pre-conditioned, microprocessor 5 sends enabling signal and to prompting module 6 and informs
Pressure anomaly position, reaches accurately to remind the purpose of user sitting posture problem.The traversal fortune of microprocessor 5
Calculate and judge to use various ways, being hereinafter exemplified.
As it can be seen, the most equally distributed 8 pressure transducer number consecutivelies be a, b, c, d,
e、f、g、h.When this pressure test device 2 works, the traversal computing of microprocessor 5 and judgement step
Suddenly following 2 steps are generally comprised:
Step 1: microprocessor 5 receives the digital signal of A/D change-over circuit 4, and reflects this signal
The force value of all pressure transducers 3 process, appoint the pressure taking 4 pressure transducers of continuous adjacent
Force value sums up, obtain the most respectively abcd, bcde, cdef, defg, efgh, fgha, ghab and
Habc this 8 groups of pressure and value, using 4 maximum for its neutralization number force value as one group, remain 4 pressures
(when such as abcd and value are maximum, abcd is as first group, and efgh is as second as another group for force value
Group), these two groups of pressure and value are poor (△ P1=Pabcd-Pefgh), and by this difference △ P1
Compare with predetermined threshold value A, when difference △ P1 is less than predetermined threshold value A, it is judged that sitting posture is in the main true nothing
Need to remind, and when difference △ P1 is equal to or more than predetermined threshold value A, then perform step 2；
Step 2: times fetch the force value from adjacent 2 pressure transducers 3 in above-mentioned and bigger group of value
Being divided into one group, remaining 2 pressure transducers 3 is another group, the pressure that 2 force value of this residue are corresponding
Sensor 3 also must be adjacent, the most again chooses.(it is such as one group with ab in this group of abcd,
Cd is another group) 2 force value respective in these two groups are added respectively and and is poor (△ P2=Pab-
Pcd), and this difference △ P2 is compared with predetermined threshold value B, when difference △ P2 is equal to or more than presetting
During threshold value B, microprocessor 5 sends enabling signal to prompting module 6, not only inform abnormal sitting posture really and
And inform which orientation stress is excessive, thus reach accurately to remind the purpose of user.
In the above-described embodiments, only carried out step 1 and 2, but the present invention has been not limited to this, actually
Stating number of steps can be with the pressure summed up in the total number of pressure transducer arranged and each step
Value number is determined.
