Further, said sensor is provided with 20～60.
The present invention compared with prior art has following beneficial effect:
The invention solves headlight for vehicles nozzle ejection Performance Detection and be confined to operating personnel's range estimation, exist very big personal error and evaluation result not have problems such as science.Headlight for vehicles nozzle ejection performance detection precision and quality level have been improved in addition greatly.
Description of drawings
Fig. 1 is a theory diagram of the present invention.
Fig. 2 is preferred embodiment structural representation of collecting unit of water impact dot matrix.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Fig. 1 shows principle of the invention block diagram; Headlight for vehicles nozzle ejection device for detecting performance; The collecting unit 100 that comprises the water impact dot matrix; Be used to gather the impact dot matrix of a certain xsect of current that the headlight for vehicles nozzle ejection goes out, institute will gather and analyse data and comprise water impact dot matrix zone and the total number of spots of water impact dot matrix.Said water impact dot matrix is every at a distance from 2 milliseconds of collections once, gives comparative analysis unit 200 after amplifying 15 times.
Described preset impact dot matrix is obtained through following manner, gets a headlight for vehicles nozzle that has been up to the standards earlier, then it is ejected in the zone, gathers these data then, obtains geometric figure through CAD software editing and preservation then.
Said headlight for vehicles nozzle ejection device for detecting performance adopts following steps that headlight for vehicles nozzle ejection performance is detected:
In the current that headlight for vehicles nozzle 4 ejects, get an xsect, gather water impact dot matrix zone and the total number of spots of water impact dot matrix that headlight for vehicles nozzle 4 ejects;
Comparison is analyzed in water impact dot matrix zone and preset impact dot matrix zone, departed from greater than 5% with the point that impacts the dot matrix zone, then be judged to be defective when relatively obtaining said water impact dot matrix zone;
Depart from less than 5% with the point that impacts the dot matrix zone when relatively obtaining water impact dot matrix zone, then total lattice point quantity of water impact and the total number of spots of preset dot matrix are continued relatively;
When relatively obtaining the total number of spots of water impact dot matrix greater than the total number of spots 95% of preset dot matrix, it is qualified then to be judged to be, otherwise is defective.
Fig. 2 shows 100 1 illustrated embodiments of collecting unit of water impact dot matrix of the present invention; Comprise slide rail 1; Be equipped with scan shaft 2 on the said slide rail 1, said scan shaft 2 is provided with 24 sensors 3, and the center of described these 24 sensors 3 is in alignment.Certainly, described sensor 3 numbers are not limited only to 24, can also be other numbers, and generally it is set between 20～60.Trace it to its cause as follows, if sensor 3 numbers less than 20, the data of gathering so are not very accurate.If sensor 3 numbers greater than 60, though improved the accuracy of data acquisition, have increased cost and unnecessary space greatly.
When the water impact dot matrix was gathered, the starting pressure pump was opened nozzle 4, and current 5 spray from nozzle 4 and form; Scan shaft 2 slippage on slide rail 1; And scan said water flow jet zone, during sensor 3, sensor 3 is every at a distance from current shock point battle array of 2 milliseconds of collections when current 5 are ejected into.Certainly, said sensor 3 also can be gathered the water impact dot matrix at interval At All Other Times, for example gathers a current shock point battle array for 1～6 millisecond.Sensor 3 will collect the water impact dot matrix and send comparative analysis unit 200 mentioned above to through USB interface or UART interface then, analyze comparison.
One of ordinary skill in the art will appreciate that all or part of step that realizes in the foregoing description method is can control relevant hardware through program to accomplish, described program can be stored in the power control machine read/write memory medium.
After judged result is come out, can also on computer monitor, show, the necessary available draught machine of words, printing machine come record, come process result output again, obtain corresponding data transmission and give the automaker.
