As shown in figure 8, the pressure capsule system includes array of pressure sensors, signal processing module, back end, nothing
Wire module, communication unit, the array of pressure sensors is using flexible fabulous and only 0.1 mm of thickness latticed tactile tension
Force snesor: Tekscan pressure sensor.10 pressure sensors are uniformly paved with helping on cushion area and both sides by the present embodiment
Hand area, the pressure data of pressure sensor output acquisition.
Network-like tactile pressure sensor is evenly arranged on handrail both sides and wheel chair cushions by the pressure capsule system
Go the various pressure characteristic values of record user.When in use, the characteristic value of sensor record is combined with single-chip microcontroller,
Different characteristic values corresponds to different output.Invention defines six kinds of characteristic values, respectively corresponds steering and its present invention is set
The distinctive of meter is lain down, and stand function.It is more intelligent to realize wheelchair by the design for pressure sensing content by the present invention
Purpose.
Common sitting posture definition includes: forward lean, is leaned back, body is left-leaning, body Right deviation, normal sitting position, unmanned shape
State.When forward lean, forward cell pressure changing value is larger in sensor array, makes single-chip microcontroller output phase that level be answered to drive
The movement of wheelchair hydraulic stem, makes wheelchair enter stance；It leans back, the cell pressure changing value in sensor array rearward
It is larger, so that single-chip microcontroller output phase is answered level driving wheelchair hydraulic stem movement, wheelchair is made to enter lying position；Body is left-leaning, sensing
Left side handrail and the sensor to keep left have apparent pressure change in device array, before making single-chip microcontroller output phase that level be answered to drive wheelchair
(deflecting roller) movement is taken turns, front-wheel (deflecting roller) is made to turn left；Body Right deviation, the right handrail and the biography kept right in sensor array
Sensor has apparent pressure change, so that single-chip microcontroller output phase is answered level driving wheelchair front wheel (deflecting roller) movement, turns to front-wheel (
Wheel) it turns right；The amount of pressure distribution of normal posture, sensor array is normal, and output electric signal keeps single-chip microcontroller to be in open-minded
State, wheelchair enter working condition；Unmanned posture, sensor array do not sense amount of pressure, and no electric signal output makes monolithic
Machine is in an off state, and wheelchair enters off-mode.
The signal processing module is for converting digital signal for the analog signal of sensor and carrying out signal amplification, originally
Embodiment carries out signal processing and digital-to-analogue conversion using HX711 chip.
The back end is controlled by single-chip microcontroller, and the pressure information for exporting HX711 is sent by serial ports.
The wireless module sends data for the back end and cloud server receives data；
The communication unit is used to the received data of the wireless module of cloud server side being sent to cloud server.
As shown in Fig. 9 (a), when user is sitting on wheelchair, sensor will record the pressure distribution of generation, can analyze
Pressure distribution data.As shown in Fig. 9 (b), in order to avoid sensor internal or the pressure disturbances of outside, using local average random fields pair
Pressure distribution data is pre-processed, and by the relevant usual position of experiment collecting sample data definition, is realized intelligentized
Operating system is more convenient the use of user.
Above-described embodiment is one of them embodiment of the present invention, but embodiments of the present invention are not by the implementation
The limitation of example, any change made without departing from the spirit and principles of the present invention of others, substitution, combine, are simple at modification
Change, should be equivalent substitute mode, be included within the scope of the present invention.
