The source electrode of field effect transistor Q4: ground connection, drain electrode: the positive pole of the fly-wheel diode VD that is connected in parallel, P2 end.
The protection philosophy of apical tooth condition monitoring circuit 3 is as follows:
By positive-negative-positive triode Q3, the tenth resistance R 10, the second resistance R 2, the 3rd resistance R 3, the 4th resistance R 4, the one NPN type triode Q1, the apical tooth condition monitoring circuit 3 that the elements such as the first capacitor C form, in order to monitor the on off operating mode of starter relay main contact, when the switch main contact in starting moment while also being in off state, contact potential is poor is the voltage of battery feed E substantially, 30 ends that are P1 end and starter motor are all 24V, and P4 end to be the 30b end be almost 0V, positive-negative-positive triode Q3 is positively biased saturation conduction state in this moment, the cathode voltage of battery feed E is given the first capacitor C 1 charging by positive-negative-positive triode Q3 through the second resistance R 2, the closing time of main contact is generally 40～70mS, and design the second resistance R 2, the time constant of the first capacitor C 1 is much larger than closing time such as the 0.2S～0.3S of main contact, consequently, before the electric charge of the first capacitor C 1 not yet is sufficient to and can triggers a NPN type triode Q1 conducting, contact is just closed, be P4 end (30b end) and P1 end (30 end) equipotential, therefore lose turn-on condition transfers cut-off state to positive-negative-positive triode Q3 at once, namely a NPN type triode Q1 maintains cut-off state, therefore field effect transistor Q4 is on state and can works until complete starting always.
As starter motor apical tooth or 30 ends open circuit, 30 and 30b end be not equipotential all the time, so above-mentioned charging process just will continue to carry out, until trigger a NPN type triode Q1 conducting, the grid voltage that makes field effect transistor Q4 is short circuit over the ground, field effect transistor Q4 cut-off, starter relay, because not having power supply voltage to stop starter motor work, so just can remind the driver to reset.This protection process, because short 0.2S～0.3S time is only arranged, is compared with manual control, has effectively limited the degree of heat of switch coil, avoids vicious circle to burn the switch coil.
The working principle of anti-reignition electric voltage observation circuit 4 is as follows:
The anti-reignition electric voltage observation circuit 4 formed by the 5th resistance R 5, the 6th resistance R 6, the 7th resistance R 7, reference diode D1, the 2nd NPN type triode Q2, be set in while being greater than 27 ± 0.2V and trigger the 2nd NPN type triode Q2 conducting, make field effect transistor Q4 be in cut-off state.When vehicle during in normal operation; system voltage generally remains on 28 ± 0.2V; as because of accident; such as the head-end ignition relay because jolting electricly or driver's misoperation reignition; make P1 hold electricly, because voltage has surpassed the 27 ± 0.2V set, the 2nd NPN type triode Q2 transient switching forces field effect transistor Q4 to be in cut-off state; starter relay will can not obtain electronic work like this, thereby protect the actuation gear of starter motor can be not impaired because stretching out.
The anti-working principle that excessively surmounts electric voltage observation circuit 5 is as follows:
How judging accurately that vehicle is in the car state of lighting a fire, is to solve the key that starter motor excessively surmounts problem.According to a large amount of starting curve analyses, find, the voltage change of vehicle power supply is regular governed, start moment, system voltage causes the voltage-drop of moment because of the huge current flow of starter motor, then along with reducing of engine resistance torque, progressively climb, the height that voltage climbs and climbing speed, the generating maximum current output that provides of function and the difference between starter motor self no load current are provided, difference is less, and even the former surpasses the latter, system voltage rises and to surpass the speed of 24V faster so, under normal matching condition, this time is greatly between 1～2S.
The present invention forms the anti-electric voltage observation circuit 5 that excessively surmounts by elements such as three-terminal voltage-stabilizing pipe D2, the 8th resistance R 8, the 9th resistance R 9, the second capacitor C 2.Three-terminal voltage-stabilizing pipe D2 is accurate adjustable voltage stabilizer spare, by the intrinsic standoff ratio of the 8th resistance R 8, the 9th resistance R 9 is set, can accurately set the turnover voltage of three-terminal voltage-stabilizing pipe D3.The present invention is set as 23.5 ± 0.2V.Start moment, although the voltage of P1 end has surpassed setting value, but the existence because of the second capacitor C 2, the voltage that 2. three-terminal voltage-stabilizing pipe D2 holds is by rising, usually only need the time of 10～20mS, the voltage of P1 end will drop into very low level such as 10V, in this time, the voltage that 2. three-terminal voltage-stabilizing pipe D2 holds can not reach the required overturn point of three-terminal voltage-stabilizing pipe D2, therefore three-terminal voltage-stabilizing pipe D2 is in cut-off state all the time, when system voltage slowly goes back up to higher voltage, for example, near 23.5V, at this moment the voltage 2. held of three-terminal voltage-stabilizing pipe D2 reaches its overturn point, three-terminal voltage-stabilizing pipe D2 becomes conducting by cut-off at once, now the voltage 1. held of three-terminal voltage-stabilizing pipe D2 is reduced to the 2V left and right by high petential, make positive-negative-positive triode Q3 conducting, then postpone a NPN type triode Q1 conducting after 200mS, the grid of field effect transistor Q4 is by a NPN type triode Q1 ground connection, field effect transistor Q4 is closed.
The anti-electric voltage observation circuit 5 that excessively surmounts is set, guarantee that system voltage surmounts in process while going back up to higher level at starter motor, but the trigger protection device turn-offs fast.If do not have overshoot to occur, or because of a variety of causes system voltage, can not go back up to 23.5 ± 0.2V of setting the time, protector will postpone to turn-off after 20～30S.
The basic protective function in limited time of this Multi-functional starting motor protector:
The grid voltage of field effect transistor Q4 is the output signal by delay circuit 2 generations in 20～30 seconds, via the first resistance R 1, provide, at a NPN type triode Q1 and positive-negative-positive triode Q3 all not during conducting, namely start when normal, the grid voltage of field effect transistor Q4 only is subjected to the control of front end delay switching circuit, time generally is set as 20～30S clock in limited time, then namely closes output signal.
The above is the embodiment of this invention, above-mentioned not illustrating is construed as limiting flesh and blood of the present invention, the person of an ordinary skill in the technical field can make an amendment or be out of shape above-mentioned embodiment after having read this specification, and does not deviate from the spirit and scope of the invention.
