Outgoing interface circuit.
As shown in figure 3, controlling the control method of assembly according to above-mentioned a kind of wiper and starter, control is as follows：
Described input-output table is as follows：
Function describes in detail as follows；
First, the control of wiper：
A) to the control of wiper interval gear：
Periodic discontinuous operation is at as shown in figure 4, windscreen wiper driving switch is adjusted to windscreen wiper interval shelves, wiper
State.When wiper is operated in discontinuous operation state, interval time can be adjusted by outside intermittent time adjusting knob, when
Between adjustable range be 2 seconds to 15 seconds.Controller monitors time adjustment knob in real time, user's control interval time at any time,
The time that wiper is again started up all is defined by the time adjustment knob currently determined time.The control of time adjustment knob is outside
The resistance of slide rheostat input, resistance adjustable range is 0~33K, and when resistance is zero, interval time is most short 2S, works as resistance
33K is arrived in value regulation, and interval time is most long 15S, and when resistance changes in 0~33K, interval time is with input resistance resistance into line
Property change.Windscreen wiper driving switch is adjusted to windscreen wiper lock catch, windscreen wiper stops after having carried out this time intermitten；
B) to the control of wiper low gear：
Windscreen wiper driving switch is adjusted to windscreen wiper low or first gear, wiper and carries out Non-intermittent work；Windscreen wiper driving switch is adjusted
It is whole to windscreen wiper lock catch, wiper stops；
C) to the control of wiper low gear：
Windscreen wiper driving switch is adjusted to windscreen wiper and rinses shelves, flusher directly works, wiper delay 2s actions, into nothing
Gap halted state, windscreen wiper driving switch being adjusted to windscreen wiper lock catch, flusher and directly stopped, wiper delay 4s stops,
I.e. when wiper and flusher switch leave windscreen wiper shelves, it be 4/3s that windscreen wiper, which scrapes a time, and wiper scrapes 3 times and stops transporting again
It is dynamic；
When three operation ranges of wiper are switched each other, after previous operation range completes whole step
Carry out the work of next gear.
D) to wiper short-circuit protection：
As shown in figure 5, windscreen wiper guard mode：Wiper is stopped, and no longer responds low speed windscreen wiper, high speed windscreen wiper, interval
Windscreen wiper, rinse windscreen wiper signal；
When wiper short circuit, into windscreen wiper guard mode, release windscreen wiper guard mode after the 2S that is delayed, wiper according to
Current windscreen wiper input signal performs corresponding function；Continuous 5 times, i.e., 10S judges short circuit, is defined as external circuit short circuit, enters
Enter windscreen wiper guard mode, after automobile re-powers and wiper is restarted, release windscreen wiper short-circuit protection state, windscreen wiper
Device normal response windscreen wiper input signal；
2nd, the control of starter：
Major function is that starter carries out starting control and protection.In order to prevent starter frequent starting and open for a long time
It is dynamic, there is 5 seconds, 20 seconds, 17 seconds defencive functions；After engine has been started up, starter does not allow to start；
5 seconds defencive functions：The shortest time that starter starts twice is 5 seconds, it is therefore an objective to prevents starter frequent starting；
Protect within 20 seconds：The maximum duration that starter allows continuously to work is 20 seconds；
Protect within 17 seconds：After starter smoothly starts engine, when engine output is effective high potential, starter is permitted
Perhaps the maximum duration to work is 17 seconds；
When engine output signal is effective high potential, starter does not allow to start.
Controller judges starter mode of operation by engine signal and starter signal synthesis：
A) engine signal judges：
Engine signal is the signal whether opened that engine feeds back to controller, and engine output feedback signal is big
It is effective high potential in 12V, engine feedback signal is effective low potential less than 8V；Engine feedback signal circle in 8V~12V,
For stochastic regime.Transmitter is in starting state when less than 8V.
B when) engine output signal is effective low potential：
Ith, when engine output signal is effective low potential, starter switch, multifunctional controller output 24V voltages are opened
Signal is to starter, if never engine output signal is fed back, after 20s, controller disconnects output automatically, and in 5s
Inside not output signal.If activator switch is always on, after 5S, controller automatically turns on output, if always without hair in 20s
Motivation signal is fed back, then controller is exported to and disconnected ... circulation to starter again.Herein for starter 20s protection and
5s is protected.
IIth, engine output signal for it is low when, be on device switch, multifunctional controller export 24V voltage signals to
Starter, if being fed back always without engine rotational speed signal in 20s, controller disconnects output automatically, if within 5 seconds
Engine output signal is effective high potential, and controller will no longer output signal；Engine output signal high potential is protected.
IIIth, when engine output signal is low, when starter switch frequent starting, controller allows the most short interval of output
Time is 5s.This is protected for starter 5s.It can prevent starter frequent starting from being damaged to caused by controller and engine.
When C) thering is the engine output signal to feed back to controller：
When engine output signal is low, starter switch is opened, multifunctional controller exports 24V voltage signals to starting
Machine, if detecting, engine output signal is effective high potential, and after 17s, controller output disconnects.17s is protected.Hereafter open again
Motivation switchs, and controller no longer exports.As long as i.e. engine output signal is effective high potential, after 17s, no matter activator switch
How to act, controller is now protected without output for engine high potential.
3rd, the control of water-level alarm：
When level sensor exposes the surface the above, water level alarm starts to alarm and indicated.
Schematically the invention and embodiments thereof are described above, this describes no restricted, accompanying drawing
Shown in be also the invention one of embodiment, actual structure is not limited thereto.So if this area
Those of ordinary skill enlightened by it, in the case where not departing from this creation objective, without creativeness design and the technology
The similar frame mode of scheme and embodiment, the protection domain of this patent all should be belonged to.
