The specific embodiment
Pneumatic protecting device of the present invention, mainly for the vehicle that has gas and stop, is arranged in the stop mechanism of automobile.This device mainly by air tank 2, spring reset air cylinder 9, accelerator rod 13, control cock 3, choke valve 14, brake chamber 12, normally closed solenoid directional control valve 4, often open solenoid directional control valve 11, check valve 10, Hall switch Q3, Q4 and magnet 5 and form, referring to Fig. 1.Air compressor 1 wherein, air tank 2, spring reset air cylinder 9, accelerator rod 13, control cock 3 and brake chamber 12 are that vehicle itself has, on this basis as long as increase once normally closed solenoid directional control valve 4, apparatus of the present invention of often having opened solenoid directional control valve 11 and 3 threeway basic comprisings.The normally closed solenoid directional control valve of the present embodiment adopts 2/2-way solenoid directional control valve, often drives solenoid directional control valve and adopts two-bit triplet solenoid directional control valve.
The stop mechanism of vehicle self mainly comprises air tank 2, spring reset air cylinder 9, accelerator rod 13, control cock 3, damper 14, brake chamber 12, normally closed solenoid directional control valve 4, often opens solenoid directional control valve 11 and check valve 10, one end of accelerator rod 13 wherein is connected with one end of Das Gaspedal 6, and one end is connected with rod end and the choke valve 14 of spring reset air cylinder 9; Brake chamber 12 is connected with brake control lever 15, and brake control lever 15 is connected with brake shoe brake cheek device 16.Magnet 5 is connected on a side of Das Gaspedal 6, and two Hall switch Q3, Q4 are placed in magnet 5 sides, on two turned positions corresponding to Das Gaspedal 6, are referred to Fig. 2.Gas circuit element in above-mentioned fender guard is communicated with by some pipelines and by the annexation shown in accompanying drawing 1: the input end of air tank 2 and mouth respectively with air compressor mouth and threeway 19 in one lead to logically, other two reduction of fractions to a common denominator of threeway 19 is not communicated with a normal-closed end of normally closed solenoid directional control valve 4 and open to atmosphere one end of control cock 3.Threeway in threeway 20 is communicated with the inlet end of another normal-closed end of normally closed solenoid directional control valve 4, one end of check valve 10 and spring reset air cylinder 9 respectively, threeway in threeway 21 is respectively with the other end of check valve 10, often open a Chang Kaiduan of solenoid directional control valve 11 and the inlet end of brake chamber 12 is communicated with, and often opens another Chang Kaiduan of solenoid directional control valve 11 and the open to atmosphere other end of control cock 3 is communicated with.
Once commutation action is just done in normally closed solenoid directional control valve 4 and 11 energisings of Chang Kai solenoid directional control valve, this two solenoid directional control valve is respectively by a relay and power connection, so as long as the switch motion of control relay just can be controlled the action of solenoid directional control valve.The switch motion of relay is controlled by control setup.Refer to Fig. 3～7, control setup is mainly comprised of micro controller system U2 and relay drive circuit (dotted line institute frame part in figure), Hall switch Q3, Q4 (Q4 does not draw) are connected with micro controller system U2 input port 14,17 pin respectively, and the output port 9,10 of micro controller system U2 is connected with relay drive circuit.Relay K 1 on this circuit, K2 are arranged on the corresponding power circuit of normally closed solenoid directional control valve 4 and Chang Kai solenoid directional control valve 11, to control the action of electromagnetic valve 4,11, complete brake, on this external this relay drive circuit, be also provided with light-emitting diode D2, loudspeaker LS1 produces optical signal and alerting signal by mistake simultaneously while occurring to step on action.In the circuit shown in Fig. 3, be also provided with by voltage stabilizing chip U1 and capacitor C 1, C2 and form mu balanced circuit and the digital display circuit that formed by components and parts such as charactron LED, aerotron Q1～Q4 etc., specifically repeat no more.
Before implementing the inventive method, need the side at accelerator pedal 6 that magnet 5 is set, on two turned positions with respect to accelerator pedal 6 of magnet 5 opposite one sides, two liang of Hall switch 1,2 are set.Accelerator pedal 6 can with respect to hinge-point rotate, magnet 5 also rotates thereupon, when the first Hall switch Q3 can first sense magnet 5, from off-state, become closure state, the circuit being connected with Hall switch Q3 so has just been connected, induced signal is by 14 inputs of micro controller system input port, now, SCM program starts (its flow process is shown in Fig. 8), start timing, when it is during through second Hall switch Q4, Hall switch Q4 becomes closure state from off-state, induced signal is by 17 inputs of micro controller system input port, at this moment micro controller system timing stops, two Hall switch that measure are sent to signal time difference T constantly compares with the time C of program setting in advance simultaneously.Setting value C is under normal condition during step on the accelerator, and first, second Hall switch in fender guard of the present invention sends respectively the time difference of two signals, and this value is to be empirical value through repeatedly testing an aviation value, gets C=0.025 second.
When occurring misoperation, be that driver is should touch on the brake pedal and misoperation accelerator pedal time, trample throttle rapid as touch on the brake rapidly, Measuring Time must be less than the time C of setting, T≤0.025, micro controller system sends signal to relay drive circuit, this circuit working, the relay switch that its mouth connects is becoming closure state from off-state, and corresponding electromagnetic valve circuit is communicated with.Normally open type magnetic valve 11 closures now, normally closed solenoid valve 4 is opened, in air tank, 2 gas divides two-way along pipeline afterwards by the normally closed solenoid valve 4 of opening, one road gas enters compressed air brake cylinder 12 by the 17a end of check valve 10, the 3rd threeway 17, at this moment the piston rod 12a of compressed air brake cylinder 12 will stretch out, drive the brake control lever in drg that brake shoe brake cheek is opened, realize braking.Another road gas enters spring reset air cylinder 9 along pipeline, and the piston rod 9a of air cylinder is stretched out, and promotes accelerator rod 20 counter motions and drives throttle gate 19 to close simultaneously, and engine oil reduces, and makes from another point of view locomotive lean on the friction on ground to reach braking.After emergency situation is removed, press reset switch S2(and refer to Fig. 3), the time meter time makes zero, now connect the circuit power-off of solenoid directional control valve, solenoid directional control valve is got back to initial condition, now the gas in spring reset air cylinder 9 flows back to atmosphere with the gas in compressed air brake cylinder 12 through check valve 10 along pipeline together with Chang Kaiduan 11b, the 11a of normally open type magnetic valve 11 and logical atmosphere end 3b, the 3a of control cock, and brake shoe brake cheek shrinks, throttle return.
When normally trampling throttle, T > C, when pedal returns, the first Hall switch 7 can sense magnet 5 again, and time meter resets and makes zero, and signal input circuit 31 starts to wait for new hall signal input.During as passed through Hall switch when Das Gaspedal once by Hall switch two, length of the halt surpasses 8.888 seconds, and time meter will stop counting, and when pedal returns, the first Hall switch senses magnet 5 again equally, and time meter resets and makes zero.In control setup of the present invention, also designed a hand switch S1(and referred to Fig. 3); when overtaking other vehicles; likely throttle can be stepped on comparatively fast; can power supply be disconnected by hand switch S1; prevent that this device from starting when overtaking other vehicles; the open and close of control single chip computer system, thus determine whether this fender guard works, and whether fender guard is shown by light-emitting diode D1 in work.
