Bidirectional-movement granule transporter uses 5 kinds of different size standard particles, 3 kinds of iron material ferromagnetism balls of concrete employing
150 microns of type, 300 microns, 500 microns；300 microns, 600 microns ball-type metallic particles of 2 kinds of copper product nonferromagnetics.Put into
Bidirectional-movement granule transporter uses the two-way normally closed electromagnetic relay of bidirectional-movement electric magnet, specially Panasonic 24V, action speed
Degree be 1 metre per second (m/s) to 30 metre per second (m/s)s, press equipment operation button 6, control circuit plate controls bidirectional-movement granule transporter even
5 kinds of different size standard particles of continuous repeatedly drive are by lubricating oil wear particle detection sensor, the response of lubricating oil wear particle detection sensor
Signal is detected by granule detection road plate, and starts to compare to control circuit plate and count, each size of automatic decision
The lubricating oil wear particle detection sensor accuracy of detection of standard particle is the most qualified.If the 5 of qualified correspondence granule display lamps 5 are respectively
Lighting instruction, display lamp specifically realizes with LED green indicating lamp.Testing result is by 422 PORT COM in detail, is uploaded to calculate
Machine analysis stores.
The response signal of lubricating oil wear particle detection sensor, is the modulated square wave relevant to metal particle size, waveform
Number is just equivalent to the number of the metallic particles detected, the amplitude size of waveform and the size linear correlation of metal worn particle；
The modulated square wave that granule detection road plate pair is relevant to metal particle size carries out detection and amplifies, and is sent to control circuit plate and enters
Row compares.Control circuit buttress is according to the size of standard particle and controls the number of times of standard metal granule action, and is detected
Square-wave signal form and square-wave signal size compare；If the square-wave signal size ideal square wave corresponding with standard metal granule is big
Little relative error is sufficiently small, and square-wave signal number is missed by the relative of lubricating oil wear particle detection sensor number of times with metallic particles simultaneously
Difference is sufficiently small, then be qualified with regard to automatic decision, is otherwise defective.
Concrete methods of realizing is, employing standard substance metallic particles and the standard transducer that manual test is qualified, even
Connect automatic detection device, according to the size automatically controlling the standard metal granule square-wave signal by sensor 10000 times
Meansigma methods is as ideal square wave size corresponding to the standard metal granule of standard.Automatically control standard particle during test to pass through every time
Test sensor 100 times, if square wave number > 97 times, the square-wave signal size ideal square wave corresponding with standard metal granule is big
Little relative error < 3%, the most automatically it is judged to that tested sensor is qualified, is otherwise defective.
The process of data acquisition is, granule detection road plate is to lubricating oil wear particle detection sensor emission high-frequency carrier signal
(10kHz when implementing), when having standard metal granule in lubricating oil wear particle detection sensor, carrier signal is modulated, and produces
Low-frequency square-wave, square wave number is metallic particles number, square-wave signal size and metal particle size size linear correlation, and granule is examined
Survey circuit board uses high speed over-sampling AD (1000KHz) to carry out signals collecting.
The process that data process is that granule detection road plate carries out probability statistics and filters noise, then to signal
It is amplified, exports square-wave signal further according to signal peak and minimum value signal.
The data characteristics gathered and process is to use high frequency sampling AD, directly gather the modulated signal of high frequency carrier, no
Loss information.Data process and use probability statistics filtering, and applicable Detection of Weak Signals is lost high frequency square wave information the most in a large number, kept away
Exempt from standard particle and passed through sensor speed, the inconsistent error that causes in position, and overcome standard particle to pass through sensing in guarantee
Device speed, position is inconsistent cause error on the premise of, add standard particle by the sensor number of times order of magnitude, fully ensure that
The statistical representativeness of sensor technology index verification, is effectively improved the degree of accuracy of detection.
The above, only this utility model preferably detailed description of the invention, but protection domain of the present utility model is not
Being confined to this, any those familiar with the art is in the technical scope that this utility model discloses, according to this practicality
Novel technical scheme and utility model thereof conceive equivalent or change in addition, all should contain at protection model of the present utility model
Within enclosing.
