Concrete using method of the present utility model is: user is sitting on wheelchair, whole honeywell switch sensor 11 is worn on head, and the Hall switch 111 after disinfecting is aimed at mouth, tie up in loins by control box 12 binder, user controls by tongue the motion that honeywell switch sensor 11 controls wheelchair;
Honeywell switch sensor 11 is fixed in the very low thick copper lines of pcrmeability, and by thick copper lines, the minimum sensing unit of 3-7 honeywell switch sensor is fixed on successively the periphery of mouth, whole honeywell switch sensor 11 is worn on head by accessory.By pressing the permanent magnet above Hall switch with tongue, make permanent magnet near Hall switch, when distance between Hall switch and permanent magnet is less than certain certain value, Hall switch senses that magnetic field intensity becomes large, Hall switch output signal will change, and outputs signal and becomes low level from high level.When tongue no longer presses the permanent magnet above Hall switch, permanent magnet is under the effect of elastic support, and Hall switch and permanent magnet return to original distance, and Hall switch output signal becomes high level from low level.According to the difference of mode of the permanent magnet above pressing Hall switch, multiple wheelchair control signal can be produced respectively, multiple wheelchair control signal be turn left, accelerate, fall back, advance, stop, slow down, the signal such as right-hand rotation.After honeywell switch sensor 11 collects signal, send signal on the receiver port of the first single-chip microcomputer 121 in control box 12, after first single-chip microcomputer 121 receives signal, by its built-in control sequence of advancing to after signal analysis, first single-chip microcomputer 121 exports signal of advancing accordingly, and the first single-chip microcomputer 121 advances Signal transmissions to bluetooth dispensing device 122 through signal sending end mouth handle.The signal that bluetooth dispensing device 122 sends is received by Bluetooth receptions device 21, Bluetooth receptions device 21 sends through the receiver port of the second singlechip 22 of master controller 2 signal received to second singlechip 22, after second singlechip 22 receives signal, program through presetting is analyzed signal, produce corresponding wheel chair sport control signal, thus reach the object controlling wheel chair sport.
The DC motor Driver principle of this utility model tongue control wheelchair is, two two different 2 system numbers are sent by the signal output port of the second singlechip 22 in master controller 2, the forward and reverse of two direct current generators are controlled by DC motor Driver module 23, the PWM voltage waveform signal of different duty is sent by the signal output port of the second singlechip 22 in master controller 2, the rotating speed of two direct current generators is controlled by DC motor Driver module 23, the signal output port of the second singlechip 22 in master controller 2 exports two-way PWM voltage waveform signal, control two direct current generators respectively, when the dutycycle increase of the PWM voltage waveform signal that the second singlechip 22 in master controller 2 exports, DC motor Driver module 23 controls the acceleration of two direct current generators, when the dutycycle reduction of the PWM voltage waveform signal that the second singlechip 22 in master controller 2 exports, DC motor Driver module 23 controls the deceleration of two direct current generators.Wheelchair accelerates the PWM voltage waveform signal exported by the second singlechip 22 in master controller 2 with deceleration dutycycle when straight-line travelling increases and reduces to carry out control realization, makes two direct current generators acceleration or deceleration simultaneously.The advance of wheelchair with retreat be by the second singlechip 22 in master controller 2 by DC motor Driver module 23 control the synchronized rotating forward simultaneously of two direct current generators 4 or simultaneously synchronized reversion realize.Wheelchair turns left, and to be second singlechip 22 in master controller 2 control left direct current generator by DC motor Driver module 23 slows down and control right direct current generator simultaneously and accelerate to realize, and wheelchair is turned right, and to be second singlechip 22 in master controller 2 control left direct current generator by DC motor Driver module 23 accelerates to control right direct current generator simultaneously and slow down and realize.Wheelchair stops be the PWM voltage waveform signal dutycycle that second singlechip 22 in master controller 2 exports is zero, controls two direct current generators stop operating simultaneously and realize by DC motor Driver module 23.
Master controller 2 can also control the light on and off of the headlamp 9 be arranged on wheelchair frame 03 heel brace frame, light intensity inductive transducer 8 changes the signal of telecommunication into light intensity, and by electrical signal transfer to light intensity inductive transducer signal processing module 28, light intensity inductive transducer signal processing module 28 changes the size of light intensity into Transistor-Transistor Logic level signal, when dim and brightness is reduced to a certain degree time, light intensity inductive transducer signal processing module 28 exports high level signal.After the light intensity inductive transducer signal processing module 28 in master controller 2 sends high level signal, second singlechip 22 sends control signal, controls headlamp driver module 27 and opens two headlamps 9.When light grow and brightness are increased to a certain degree, light intensity inductive transducer signal processing module 28 output low level signal.After the light intensity inductive transducer signal processing module 28 in master controller 2 sends low level signal, second singlechip 22 sends control signal, controls headlamp driver module 27 and closes two headlamps 9.
Because wheelchair is in the process retreated, the driver of wheelchair is difficult to observe wheelchair situation below, cause danger in order to avoid wheelchair bumps against barrier in the process retreated, in the below of the wheelchair chair back, ultrasonic distance-measuring sensor 5 is installed, when wheelchair rollback runs into barrier, when the distance of wheelchair and barrier is less than a certain setpoint distance, in order to avoid wheelchair and barrier collide, second singlechip 22 in master controller 2 sends control instruction, make wheelchair hard brake stop, and send warning, wheelchair driver rear is reminded to run into barrier, wheelchair driver can manipulate wheelchair and travel forward, when wheelchair sails out of a certain setpoint distance of barrier, stop alarm.Then wheelchair driver can select other retrogressing route.
While tongue controls wheel chair sport, wheelchair is also by the control of radio remote controller 70.Radio remote controller 70 has four control knobs, is respectively advance, retrogressing, turns left and right-hand rotation button.Radio remote controller 70 sends control command, the wireless remotecontrol reception antenna 7 be installed on wheelchair receives, and by signal transmission to radio remote-controlled signal decoder module 26, signal is decoded, four different control commands are decoded as four 4 different binary codings, after having decoded, decoded signal is passed to the second singlechip 22 in master controller 2 by radio remote-controlled signal decoder module 26 by the signal input port of the second singlechip 22 in master controller 2, after second singlechip 22 detects the signal of signal input port, according to the program preset, send corresponding control instruction, control the running status of two direct current generators 4, thus control the motion of wheelchair.
