Embodiment two
The present embodiment can be based on above-described embodiment, there is provided a kind of preferred embodiment, with reference to shown in figure 1.This implementation
Example can carry out the measurement of windshield wiper swing angle and hunting frequency, and pass through Computer display by parameter is swung.
The utility model embodiment provides a kind of windshield wiper TT＆C system, including：Gripping sleeve 1101, opening sleeve 1102,
Universal coupling 1103, encoder 120, support 130, workbench 140, PLC 150 and computer data acquiring processing dress
Put.
Wherein, gripping sleeve 1101, opening sleeve 1102 and universal coupling 1103 connect windshield wiper output shaft and encoder
120, send the mechanical rotation of windshield wiper output shaft to encoder 120；Encoder 120 detect mechanical rotation rotational angle and
Rotation direction, and encode to be formed corresponding to digital quantity；The digital quantity of the output of PLC capturing and coding device 120 and processing, are obtained
The swing parameter of windshield wiper；The every of Computer signal acquisition processing device collection PLC output swings parameter, is organized into
Technology form is simultaneously shown.
Further, encoder 120 uses high-precision increment type AB phase encoders, and AB phase decoder internals have two pairs of photoelectricity
Coupler, phase difference output are 90 ° of two group pulse sequences, and the advanced of two-way pulse, lagged relationship be just when rotating and reverse
On the contrary, when rotating and reverse therefore the level height of A phases pulse is just on the contrary, use AB phase encoders, PLC can be very
Easily identify the direction of rotating shaft rotation.By gather AB phases encoder export digital quantity change can accurate simulation scrape
The motion process of rain device, and then the accurate every swing parameter for calculating windshield wiper.
The detection process of specific progress swing angle and hunting frequency is as follows：
It is to be fixed on the output shaft of windshield wiper with encoder to measure the hunting frequency of windshield wiper and the process of swing angle
On same level central point and together moved in coaxial, measures the hunting frequency of windshield wiper and the functional characteristic of swing angle.
Measuring the process of windshield wiper swing angle is：First allowing windshield wiper to be powered rotates window wiper motor, when motor rotates
Slowed down by worm screw, turbine, the windshield wiper output shaft for making to be connected with turbo-eccentric moves reciprocatingly.Encoded by increment type AB phases
Device gathers the mechanical rotation of windshield wiper output shaft, and because windshield wiper work is to move back and forth, the track of motion is a sector, past
Multiple swing angle is in the range of 0 ° to 90 °, so maximum of the data of collection not over AB phase encoders, AB phases encode
Device gathered data when positive direction operates is incremented by, and when opposite direction operates, gathered data is successively decreased, so windshield wiper is run once
Gathered data has maximum and minimum value, the digital quantity of PLC collection AB phases encoder output, passes through the digital quantity of collection
Maximum and minimum value be calculated the absolute value of windshield wiper operation once, it is 1024 digital quantities that can use one week
AB phase encoders, one week is 360 degree, can finally draw the swing angle JIAO=(ABS/1024) * 360 of windshield wiper.
Measuring the process of windshield wiper hunting frequency is：First allowing windshield wiper to be powered rotates window wiper motor, when motor rotates
Slowed down by worm screw, turbine, the windshield wiper output shaft for making to be connected with turbo-eccentric moves reciprocatingly.When windshield wiper output shaft starts
After rotation, the mechanical rotation of windshield wiper output shaft is switched to for digital quantity, then control by PLC using increment type AB phases encoder
For the data volume of device collection processed instantly as reference value such as D100, it is T1 to start timing when occurring D100 for the first time, works as windshield wiper
Operation 2 cycles after PLC gather data D100 three times occurs, when occurring D100 for the third time, under meter the current time be
T2, it can thus show that the time that windshield wiper runs used in 2 weeks is T=T2-T1, that is to say, that windshield wiper was run used in one week
Time be T/2, then one minute operation number be N=60/ (T/2), the hunting frequency that can finally draw windshield wiper is N
It is secondary.
When carrying out the measurement of swing angle and hunting frequency, it can also take multiple measurements, take the average value repeatedly measured
As final swing angle and hunting frequency.
Computer data acquiring and processing unit collection PLC calculate the swing angle of windshield wiper and swing frequency
Rate, come out to swinging formation technology report display after parameter arranges.
The windshield wiper TT＆C system that the present embodiment provides, it is capable of the motion process of accurate simulation windshield wiper, coupled computer
Data acquisition and processing unit, accurate measurement and the swing parameter of windshield wiper can be shown.
Pay attention to, above are only preferred embodiment of the present utility model and institute's application technology principle.Those skilled in the art's meeting
Understand, the utility model is not limited to specific embodiment described here, can carried out for a person skilled in the art various bright
Aobvious change, readjust and substitute without departing from the scope of protection of the utility model.Therefore, although passing through above example
The utility model is described in further detail, but the utility model is not limited only to above example, is not departing from
In the case that the utility model is conceived, other more equivalent embodiments can also be included, and the scope of the utility model is by appended
Right determine.
