Specific embodiment
The present invention is described in further detail with reference to the accompanying drawing and by embodiment, and following embodiment is to this hair
Bright explanation and invent and be not limited to following embodiment.
Referring to Fig. 1-Fig. 4, one kind of the present embodiment is every empty gesture stability wheelchair, including including attitude controller, wheelchair,
Wherein the attitude controller includes double-shaft tilt angle sensor, four-way coded transmitter, switch 1, charging interface 2, elastic bunch
Band 3, band adjuster 4, the wheelchair include decoding receiver, drive control device, backrest 5, driving motor group 6, directive wheel 7,
Battery pack 8, wheelchair base support 9, cushion support 10, cushion 11, handrail 12.
Attitude controller:
Double-shaft tilt angle sensor, supply voltage 5v, (0 to 180 ° of corresponding 0.5v are arrived the output degree of the analog quantity of sensor
4.5v), DO1~DO4 is sensor digital amount output end, can cooperate adjusting knob setting alarm angle, reach defeated when setting value
Effective low level out.Obliquity sensor is mostly used to measure change of pitch angle amount with respect to the horizontal plane.Theoretical basis is exactly newton
Two laws, according to basic physical principle, in an internal system, speed is unable to measure, but can measure its acceleration
Degree.If initial velocity by integral calculation it is known that can go out linear velocity, and then can calculate straight-line displacement.So it its
It is a kind of acceleration transducer with principle of inertia in fact.When obliquity sensor is static i.e. side and vertical direction do not add
Speed effect, then acting on the only acceleration of gravity above it.Between gravity vertical axis and acceleration transducer sensitive axis
Angle be exactly inclination angle.
Four-way coded transmitter, for operating voltage range in 3V-9V, transmission power is big, low in energy consumption, stable and reliable for performance.
Using SMD technology, most advanced sound table resonator (SAW) element is used in frequency stabilization processing, circuit board (PCB) uses dielectric loss
The smallest material.Production technology is exquisite, and import instrument debugging, stringent QC high temperature is powered on aging before factory.It can with decoding circuit
It directly uses, is widely used in remote data wireless transmission, wireless remote control, the occasions such as burglar alarm.Address code welding section: one
Totally 8, it can be set as vacancy, high level (H), low level (L) respectively.Using be address code can with self-defining weld or more
Change.Numeric data code sets area: 4, only there are two states for numeric data code: high level and low level.Here there was only a kind of state of high level,
When a wherein foot for chip is set as high level, the corresponding output high level of corresponding receiving module.
Decoding receiver, four figures are received according to wireless receiving, burglar alarm signal；Remote control, telemetering, remote sensing；Work
Make voltage: DC 5v2. operating current :≤4mA (DC 5V)；Working frequency: 315MHZ；Bandwidth: 2MHz (315MHz；Under sensitivity
It is tested when dropping 3dBm；Sensitivity: it is better than -105dBm (50 Ω)；Rate: < 5Kbps (315MHz, -95dBm.
Wheelchair: the driving motor group 6 is equipped with driving motor 13, speed reducer 14, driving wheel 15, with wheelchair base support 9
It is fixedly connected；The directive wheel 7 is fixed with wheelchair base support 9 by fixed screw；The battery pack 8 is solid by embedding grammar
It is detachable battery pack due to wheelchair base support 9；The cushion support 10 is adjustable shock-absorbing support frame, with wheelchair
9 sets of embedded connections of base support；The backrest 5 is fixed on cushion support 10, is adjustable backrest；The handrail 12 is fixed
It is adjustable armrest on cushion support 10.
When attitude controller works, double-shaft tilt angle sensor converts digital signal for headwork and is encoded by four-way
Transmitter transmits a signal on the decoding receiver on wheelchair, and decoding receiver receives signal and transmits a signal to driving control
Device processed, drive control device receive signal control driving motor group and directive wheel.
Above content is only illustrations made for the present invention described in this specification.Technology belonging to the present invention
The technical staff in field can make various modifications or additions to the described embodiments or by a similar method
Substitution, content without departing from description of the invention or beyond the scope defined by this claim should belong to this
The protection scope of invention.
