Two, the control strategy of starter long duration test controller
1, the control of fuel pump control relay
After the energising of starting motor of automobile durability test apparatus, electrician on the main control module of starter long duration test controller
Making, S1 is set low level by delays time to control 1, and fuel pump control relay works and connects the operating circuit of electric fuel punp (to electricity
Dynamic fuel pump is powered).
Delays time to control 1 needs S1 is set high level in situations.
If 1. in 5s clock, starter long duration test controller S8 or (S5 and S6) unreceived engine rotational speed signal, prolong
Time controls 1, and to put S1 be high level, cuts off the hookup of electric fuel punp.
2, the control of control relay is started
Delays time to control 1 is put and S1 is set low level 3s(i.e. fuel pump control relay work 3s) after, delay control circuit II
S2 is set low level, starts control relay and work and connect operating circuit (the i.e. electrician in electromagnetic switch of electromagnetic switch P4
Make).After electromagnetic switch work 5s, S2 is set to high level by master control module controls delay control circuit II, cuts off electromagnetic switch work
Make circuit, start motor and quit work.And so forth.
Delay control circuit II needs to set high S2 level in situations, cuts off electromagnetic switch operating circuit.
1. accumulator voltage monitoring module S7 monitors battery tension UinDuring≤10.5V, S2 is set to high level.
2. starting current monitoring module monitors is to current sensor signal I of S3in=Imax, i.e. start motor rotation blockage.
3, starting state identifying unit
Starting state identifying unit is according to engine rotational speed signal n1Or n2The electricity arrived with a starting current monitoring module monitors
Flow sensor signal IinThe starting state of electromotor is made and starts successfully or start unsuccessfully two states and judge.And according to startup
State carries out counting, store and exporting.
1. engine speed n1Acquisition module/engine speed n2Acquisition module.
Engine speed n1The engine speed that acquisition module gathers is from tach signal (the usually PWM of Engine ECU
Signal) or from Hall type crankshaft position sensor signal.Directly and the engine start rotating speed n of comparator one0Contrast, and defeated
Go out comparative result to judge for starting state identifying unit.
Engine speed n2The engine speed that acquisition module gathers is from magneto electric type crankshaft position sensor, through shaping
With the engine start rotating speed n of comparator one after circuit0Contrast, and export comparative result for the judgement of starting state identifying unit.
After S2 is set low level by delay control circuit II, engine speed n1Acquisition module or engine speed n2Gather mould
Block constantly gathers engine rotational speed signal n1Or n2And with electromotor starting speed n of comparator one0(n0Manual by testing crew
Input) compare, and export comparative result for the judgement of starting state identifying unit.
2. starting current monitoring modular
After delay control circuit II (S2) sets low level, starting current monitoring modular is according to the current sensor monitoring S3
Signal IinAfter comparator two, result is defeated by starting state identifying unit, (unloaded, completely to the duty starting motor
Braking and load) judge.
4, count and store
The n that starting state identifying unit inputs according to comparator oneinI with comparator two inputinStarting state is carried out
Judge.
(1) if nin≥n0And I0≤Iin≤ImaxJudge that electromotor starts successfully.Enumerator starts counting up, and the counting cycle is
The level conversion of delay control circuit II (S2), the counting moment is the S2 high level moment to low transition, often changes once,
Enumerator is that electromotor completes once to successfully start up and added up and be saved in memorizer by successful for startup number of times, calls for user
Check.It count down to time 50,000 times (this number of times can be inputted by man machine interface with tester, and maximum is set as 100,000 times) cut off
The power supply of starter long duration test controller, stops test.
(2) if nin＜ n0, it is determined that engine start failure.And according to IinIt is analyzed judging
If 1. Iin≤I0, it is judged that starter dallies.Enumerator starts counting up, and the counting cycle is delay control circuit II (S2)
Level conversion, counting the moment be the S2 high level moment to low transition, often change once, counting once.
If 2. Iin=Imax, it is judged that starter is braked completely.Automatic Program cuts off the electricity starting motor long duration test controller
Source, endurancing stops.
5, export and show
Output: show (wishing the starting state that can be stored by computer inquiry) by man machine interface.
Above-described is only embodiment of the present utility model, and in scheme, the known general knowledge such as concrete structure and characteristic is at this
Too much describe.It should be pointed out that, for a person skilled in the art, in the premise without departing from this utility model structure
