Specific embodiment
With reference to Fig. 1, Fig. 2 and Fig. 3, sitting posture correcting device includes mat applying 1, control unit 41, two infrared detecting devices A, B
With reminding unit 42.Position acquisition device and thermostat are provided on mat applying 1, the common heating such as heater strip can be used in thermostat
Device can then realize the heating to mat applying 1.
With reference to Fig. 4, position acquisition device includes upper wrapping layer 14, weft layer, insulating layer, warp layer and lower wrapping layer 15,
Warp layer is provided with the warp 11 of more parallel arrangements, and weft layer is provided with the weft 12 of more parallel arrangements, warp 11 and latitude
Line 12 is in interlaced arrangement, and insulating layer 13 is between warp 11 and weft 12, and insulating layer 13 is in the point of intersection of warp 11 and weft 12
Through hole 131, upper wrapping layer 14 and lower wrapping layer 15 is offered to carry out weft layer, insulating layer, warp layer package protection and be located at
Mat applying 1.When mat applying is pressed, pressing position can fall at some through hole 131 or certain several through hole 131, due to being pressurized, therefore pass through
Line 11 and weft 12 will be close in through hole 131 and be electrically connected, therefore can be according to which root of acquisition or which root warp 11 or weft 12
Conducting can then obtain the horizontal position information of point of intersection.Then, position acquisition device can send position signal (X, Y)
To control unit 41, certain location information can include multiple positions.In addition, the position acquisition device in the present embodiment is
It is obtained by the way of latitude and longitude, position acquisition device can also be using the plane capacitance or plane infrared scan that multiple spot is arranged also
It can obtain the location information of the horizontal level of mat applying.
Infrared detecting device A and B are identical, therefore are illustrated by taking infrared detecting device A as an example, infrared detecting device A
Including housing, accommodating chamber is provided in housing, is provided with infrared sensor and horizontal rotation apparatus in accommodating chamber, housing it is outer
Wall is provided with dark lens, and infrared detection signal may pass through lens.Infrared sensor is arranged on horizontal rotation apparatus and can be with
Horizontal rotation apparatus rotates in the horizontal direction, and infrared sensor emits infrared detection signal, and two infrared inspections upward
Left side and right side that device A, B are separately positioned on mat applying 1 are surveyed, and emits infrared detection signal towards same search coverage.It is horizontal
Rotating device can be used stepping electric rotating machine and drive rotation, and angular transducer and infrared sensor are combined into a set of module, energy
The launch angle of distance signal and infrared ray is enough obtained using infrared ray.
With reference to Fig. 5 and Fig. 9 and Figure 10 is combined, the bearing calibration of sitting posture correcting device is illustrated below.
The bearing calibration of sitting posture correcting device includes：
User is write or is read on mat applying, and hand or arm can be pressed against on mat applying, therefore position acquisition device obtains table
Location information at the compression of pad 1 due to being usually to have left arm and right arm, such as Fig. 2, therefore can obtain the position of X points and Y points
Confidence number, position acquisition device is to 41 outgoing position signal of control unit；
Due to knowing the position of arm, therefore the head of user generally can be between X points and Y points, therefore control unit 41 is according to position
Signal level control tumbler rotates, and then infrared sensor is driven to rotate in the horizontal direction, make infrared sensor to X points and
Search coverage between Y points is scanned, and so just greatly improves Scanning Detction efficiency；
Infrared sensor emits infrared detection signal towards search coverage, and can receive feedback signal, and when transmitting has transmitting
The elevation angle, infrared detection signal are that oblique Shangdi is emitted.
And feedback signal includes the range information and angle information of head distance sensor, and the position signal of two arms
It can be by estimating head position, therefore can be using feedback signal, range information and angle information as parameter, then control unit 41
The vertical height of determinand is calculated according to feedback signal and position signal, you can the height of head distance mat applying is calculated；
Control unit 41 judges whether vertical height is less than predetermined threshold value, and such as vertical height is less than predetermined threshold value, as shown in Figure 10,
Represent that reading distance is too low, then control unit 41 controls reminding unit 42 to send prompting message, and reminding unit 42 may include sounding
Module, light modules etc., and Fig. 9 then represents that reading distance is normal condition.
With reference to Fig. 6, do not use during position acquisition device certainly or when hand is not pressed into mat applying by user, infrared detection
The position that the mode for rotating horizontally and scanning obtains user's head then can be used in device A and B, and infrared detecting device A can be from left to right
Ground is scanned, and infrared detecting device B can be scanned from right to left, and when user is at J positions, then such as Fig. 7 is shown instead
Oscillogram is presented, therefore can accurately know that the head of user is to be located at J to locate, and when user be at K positions, then feeds back as Fig. 8 is shown
Oscillogram, thus can accurately know user head be located at K locate, then be also can according to range information and angle information calculating
It draws the vertical height of determinand, then monitors sitting posture state in real time.
Therefore first can by the position acquisition device of mat applying or human hands position, and by horizontal direction into
The infrared sensor of row scanning, and using the position of infrared sensor detection human body head, would know that human body head apart from infrared
The distance of sensor can also know relevant angle, and the height of human body head can be drawn finally by calculating, you can in real time
Sitting posture and reading distance are monitored, when too low reading distance, then reader can be informed by reminding, then realize that intelligence is anti-near
Depending on and sitting posture correcting.
