Detailed description of the invention
As it is shown in figure 1, the present invention includes that temperature sensor signal collecting unit 2 collecting temperature measures sensor 5
Temperature information after pass to CPU control unit 1, tach signal collecting unit 3 gathers electromotor simultaneously
Rotary speed information passes to CPU control unit 1；CPU control unit 1 controls starting relay K1, point respectively
Fiery relay K 2, the sum relay K 3 that starts, success sum relay K 4, blower fan relay K 5, warning
Relay K 6 action, and then control starter work.CPU control unit 1 connects circuit protection unit 4.
Tach signal collecting unit 3 is vortex type proximity switch.
The analog signals of CPU control unit 1 gathers port and is acquired starter Current Temperatures, if reaching
To fan starting design temperature, blower fan relay K 5 works, and blower fan is opened and carries out air-cooled to starter, directly
Reach to shut down design temperature to temperature.
Starting relay K1, ignition relay K2 control to start disconnecting relay K7 respectively, igniting isolation continues
Electrical equipment K8 works.
Test device is after setting the starter operation time, and the igniting output port of CPU control unit 1 connects
Logical, ignition relay K2 obtains electric, and igniting disconnecting relay K8 obtains electric, and ignition control unit works.Simultaneously
The startup output port of CPU control unit 1 is connected, after starting relay K1 connects, and CPU control unit 1
On-off model gather port dock nearly switching signal be acquired calculate, and with the tach signal collected
Value contrasts with starting successfully speed setting value, if more than or equal to setting value, judging to start successfully, and success
Sum relay K 4 is connected, and starts success counter and counts once；If less than setting value, judging to start successfully,
Success sum relay K 4 is disconnected, and starts success counter and does not counts.
The analog signals of CPU control unit 1 gathers port and is acquired starter Current Temperatures, if reaching
To fan starting design temperature, blower fan relay K 5 works, and blower fan is opened and carries out air-cooled to starter, directly
Reach to shut down design temperature to temperature.Starting relay K1, ignition relay K2 control to start isolation respectively
Relay K 7, igniting disconnecting relay K8 work.
After starter runs the setting time, igniting output port is connected, and K2 relay obtains electric；K2 relay
5-3 port is connected, and K8 relay obtains electric, and ignition control unit works.
After K1 connects, CPU on-off model gathers the nearly switching signal of port docking and is acquired calculating,
CPU contrasts with starting successfully speed setting value according to the tacho signal value gathered: more than or equal to setting value
Then judging to start successfully, K4 connects, and starts success counter and counts once；Then judge less than setting value to start
Success, K4 disconnects, and starts success counter and does not counts.
Analog signals gathers port and is acquired starter Current Temperatures, if reaching fan starting to set temperature
Degree, K5 relay works, and blower fan is opened and carries out air-cooled to starter, until temperature reaches to shut down sets temperature
Degree.
In order to avoid failure test number (TN) is too much, set startup sum and start successfully sum difference protection, if
Reaching setting value, whole program stopped exports, and the external acousto-optic of equipment is reported to the police, and reminds testing crew test
Stopping for some reason, have laboratory technician's acknowledgement state only, hand-reset just can be tested.
As shown in Figure 6, after the present invention switches on power, on alternating interface between man and computer, it can be seen that start, stop
Only and SR, starter Current Temperatures, start total, success sum and blower fan duty.For
Avoid testing in the past and may first click on stop button before test to testing generation impact now, clicking on
SR, to ensure that CPU control unit 1 internal data is eliminated completely；When starting to test, click is opened
Dynamic button, CPU control unit 1 can perform work automatically, and automatic test procedure is as follows:
First K1 relay obtains electric, and after K1 relay 5-3 port is connected, K7 relay obtains electric work, starts
Machine rotates the N second (test requirements document rotation time), now starts sum electronic counter and has counted once；Start
Machine runs M second (test requirements document time) K2 relay afterwards and obtains electric, K8 after the connection of K2 relay 5-3 port
Relay obtains electric work, and ignition control module obtains electric, and engine ignition starts；Electromotor is turned by proximity switch
Speed is acquired calculating, if more than or equal to setting value, it is determined that start successfully, K4 relay works, and starts into
Merit rolling counters forward counting is once；If unsuccessful, K4 relay does not works, and starts success counter and disregards
Number, but test may proceed to carry out, and whole process will not stop because of this time starting failure；Process of the test
In, starter temperature is monitored in real time and monitors on the touchscreen, if starter temperature is higher than 60 DEG C, and K5 relay
Device works, and cooling blower is opened, until starter temperature is down to 30 DEG C of stoppings, and when fan operation, touches
Touch screen fan state display green；If startup sum and the difference starting successfully sum reach setting value in test,
Test can stop and K5 relay obtains electric, and acoustooptic alarm system is started working, and reminds testing crew to current examination
Testing object and carry out state confirmation, personnel the most to be tested confirm that reason hand-reset could continue test.
The present invention produces interference, present invention profit for avoiding starter to start instantaneous large-current to signal acquiring system
Isolate control car load relay with 24V DC relay, control starter by the work of car load relay
Operating, such design can be prevented effectively from the cpu signal collection mistake that electromagnetic interference causes, thus improve
The accuracy of test；On the touchscreen it can be seen that start sum, successfully start up sum, current starter temperature
Degree, in order to avoid ineffectivity is tested, if startup sum reaches setting value with starting successfully sum phase difference, whole
Individual test suspends, and acoustooptic alarm system can respond, after personnel the most to be tested determine state, manually
Reset can continue test；Test prevents starter because of the too high inefficacy of temperature, increase temperature protection, arrive
The temperature cooling blower set is opened, and starter is carried out cooling down；The increase of electronic counter, can prevent
Only in the case of touch screen is unreadable, remain to correctly read the number of times of test.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by upper
State the restriction of mode, as long as have employed the various improvement that technical solution of the present invention is carried out, or the most improved directly
It is applied to other occasion, all within protection scope of the present invention.
