Pole enters relay K2 negative power supply input terminal through NPN triode VT2 power amplification, paraphase, and then, relay K2 obtains electric suction
It closes it and controls power input and normally opened contact end closure；Due to the triggering power supply of the second cue circuit music integrated circuit A4
2 foot of input terminal is connected with relay K3 normally opened contact end by conducting wire, and music integrated circuit A4 is in obtain electric standby mode, institute
With after the 2 feet input triggering power supply signal of music integrated circuit A4, in music integrated circuit A4 internal circuit and peripheral cell pole
Under property capacitor C4, polarity free capacitor C3, resistance R6 collective effect, the 3 foot output audio signals of music integrated circuit A4, output
Audio signal enters the one end loudspeaker B after NPN triode VT6 power amplification, then, loudspeaker B issue it is loud " please to the right
The prompt of turning ", student can carry out correct driver behavior according to prompting；When coach thinks that the driver behavior of student restores just
Chang Hou presses second key switch S3 of remote control panel again, and then, radio transmitter A6 launches the second tunnel and wirelessly disconnects letter
Number, after wireless receiving circuit A2 receives wireless cut-off signal, second 3 foot of output end no longer exports high level signal, after
And relay K2 power loss stops being attracted, the second cue circuit power loss stops working, loudspeaker B no longer makes a sound.Wireless receiving
Unit, the second cue circuit, in third cue circuit: when coach feel student drive brake when (for example coach feels vehicle
Running track exception), third key switch S3 on remote control panel A6 is pressed, then, radio transmitter A6 finished product is launched
Closure signal that third road is wireless, wireless receiving circuit A2 are received after third road is wirelessly closed, and 4 foot of third output end can be defeated
High level out, high level enter NPN triode VT3 base stage through resistance R3 current limliting, through NPN triode VT3 power amplification, paraphase into
Enter relay K3 negative power supply input terminal, then, relay K3 obtains its control power input of electric actuation and normally opened contact end is closed
It closes；Since 2 foot of triggering power input of third cue circuit music integrated circuit A5 and relay K3 normally opened contact end pass through
Conducting wire connection, music integrated circuit A5 are in obtain electric standby mode, so, the 2 feet input triggering power supply of music integrated circuit A4
After signal, make jointly in music integrated circuit A5 internal circuit and peripheral cell polar capacitor C6, polarity free capacitor C5, resistance R7
Under, the audio signal of the 3 foot output audio signals of music integrated circuit A5, output is laggard through NPN triode VT7 power amplification
Enter one end loudspeaker B of the second cue circuit, then, loudspeaker B issues the prompt of loud " please brake ", and student is according to prompting
It can carry out correct brake；After brake, coach presses remote control panel third key switch S4 again, then, wirelessly
Transmit circuit A6 launches the wireless cut-off signal in third road, after wireless receiving circuit A2 receives wireless cut-off signal, third
A 4 foot of output end no longer exports high level signal, and then, relay K3 power loss stops being attracted, and third cue circuit power loss stops
Work, loudspeaker B no longer make a sound.In radio receiving unit, braking mechanism: being unable to control vehicle when coach thinks that student drives
When (such as coach feel vehicle operation exception do not controlled by student), press the upper 4th key switch S4 of remote control panel A6, in
It is that radio transmitter A6 finished product launches the 4th wireless closure signal in road, and it is wireless that wireless receiving circuit A2 receives the 4th road
After closure, the 4th 5 foot of output end can export high level, and high level enters NPN triode VT4 base stage through resistance R4 current limliting,
Enter relay K4 negative power supply input terminal through NPN triode VT4 power amplification, paraphase, then, relay K4 obtain it is electric be attracted its
Control power input and normally opened contact end closure；Since silicon-controlled VS anodic control pole is normally opened through resistance R8 and relay K4
Tip side is connected by conducting wire, so, silicon-controlled VS can be triggered this moment, relay K5 obtains its control power input of electric actuation
It is disconnected with normally-closed contact end, due to, relay K6 cathode power supply input terminal is connected with relay K4 normally opened contact end by conducting wire,
So this moment, relay K6 can obtain two control power inputs of electric actuation and be closed respectively with two normally opened contact ends；Due to vapour
Piece conducting wire of key power switch SB is divided into two sections on vehicle, piece conducting wire one end key power switch SB and relay K5 on automobile
It controls power input to connect by conducting wire, piece conducting wire other end of key power switch SB and the normally closed touching of relay K5 on automobile
Point end is connected by conducting wire, so this moment, automobile key power switch SB, which is equivalent to, to be in close state, flameout of automobile engine
It no longer rotates；Due to the motor M positive and negative polarities power input point of the two normally opened contact ends relay K6 and motor decelerating mechanism
It is not connected by conducting wire, so this moment, the motor M meeting work once electrified of decelerating through motor equipment, in the inside machine of decelerating through motor equipment
Under structure effect, the output shaft of decelerating through motor equipment, which rotates clockwise, winds metal soft drawn rope, and metal cable wire steps on braking automobile
Plate pulls down, braking automobile, prevents student from continuing driving and causes the accident；After automobile has stopped, and then coach presses again
The 4th key switch S4 of remote control panel A6, then, radio transmitter A6 launches the 4th wireless cut-off signal in road, wireless receiving
After circuit A2 receives wireless cut-off signal, the 4th 5 foot of output end no longer exports high level signal, then, relay K4
Power loss stops being attracted, and the motor M power loss of braking mechanism stops working, do not continue to pull down brake pedal, prevent braking mechanism
Motor M rotate break bowden cable always；Since one-way SCR VS has self-locking property, so being always maintained at after being triggered
On state, relay K5, which can be also always maintained at, continues to obtain electric attracting state, prevents relay K4 power loss from stopping being attracted control electricity
After source input terminal is connected to normally-closed contact end, automobile key power switch SB is connected, and user is not turned off key power switch
When SB, automobile is again started up, and when needing to be again started up automobile, turns off the power switch S1, and all circuits return to original state, is learned
Member can normally start driving again；Brake-pedal of automobile pulls down, after braking automobile, when driver needs to restart automobile,
Change-over switch S6 is opened, due to motor M negative and positive the two poles of the earth of the positive and negative two-stage power output end of change-over switch S6 and motor decelerating mechanism
Power input is connected by conducting wire respectively, so this moment, the motor M meeting work once electrified of decelerating through motor equipment, in decelerating through motor
Under the internal mechanism effect of equipment, the output shaft of decelerating through motor equipment, which rotates counterclockwise, loosens metal soft drawn rope, braking automobile
Pedal is restored to no braking state, closes change-over switch S6 afterwards in place, and student can normally continue to drive a car.The utility model exists
