Brief description of the drawings
Fig. 1 is the structured flowchart of the touchless yarn photoelectric detection system of the utility model based on PS/2 agreement.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, the touchless yarn photoelectric detection system of the utility model based on PS/2 agreement, comprise: generating laser, PSD position sensitive detector, microcomputer, man-machine interface and audible-visual annunciator, wherein, generating laser be arranged on the yarn (being yarn to be measured) produced directly over; PSD position sensitive detector be arranged on the yarn (being yarn to be measured) produced under; Microcomputer is connected with generating laser, PSD position sensitive detector and man-machine interface respectively, the work of microcomputer control generating laser, and microcomputer carries out transfer of data by PS/2 transportation protocol and PSD position sensitive detector; Man-machine interface is connected with audible-visual annunciator.
Be converted in order to realize the analog signal that PSD position sensitive detector is detected the data signal that microcomputer can be processed, the utility model also comprises signal conditioning circuit and A/D modular converter, signal conditioning circuit comprises signal input part and signal output part, and signal input part is connected with PSD position sensitive detector; A/D modular converter comprises input end of analog signal and digital signal output end, and wherein, input end of analog signal is connected with signal conditioning circuit output, and digital signal output end is connected with microcomputer.
The present embodiment PSD position sensitive detector used is one dimension position sensitive detector or two-dimensional position-sensitive sensor; Microcomputer is single-chip microcomputer, DSP, Programmable Logic Controller, arm processor or Industrial Control Computer; Man-machine interface is touch-screen or LCD liquid crystal display or PC with keyboard; Acoustic-optic alarm comprises buzzer and LED lamp, and wherein LED lamp is red light emitting diodes or blue LED.
The course of work of the present utility model is as follows:
After spinning machine work, the yarn of producing starts output.Open man-machine interface, send order by man-machine interface to microcomputer, control generating laser Emission Lasers.Laser, through yarn, arrives the sensitive surface of PSD position sensitive detector.
In the time that the big or small thickness of yarn is different, or in the time there is broken yarn in yarn, or when yarn movement or while not moving, the laser that the sensitive surface of PSD position sensitive detector receives also just changes, and the output end signal of PSD position sensitive detector also can change.The output end signal of PSD position sensitive detector, after the conditioning and amplification of signal conditioning circuit, carry out analog-to-digital conversion through A/D analog-to-digital conversion module again, finally the signal after conversion is sent in microprocessor, microcomputer is according to the signal receiving, through processing, draw the state of yarn, and the standard state of the real-time status of yarn and yarn is compared, judge yarn size thickness, have or not broken yarn, the information such as motion state, again these information are sent to man-machine interface and show, for staff, spinning machine is carried out to operational processes.When the state of yarn has exceeded after production standard, too slightly or too thin, there is broken yarn in yarn, or yarn is extremely static, in man-machine interface, can show corresponding yarn conditions, in order to prevent the generation of substandard products, trigger audible-visual annunciator, tell staff that yarn conditions is undesired.
In microcomputer of the present utility model, store standard compliant yarn information, the yarn that produces after Ear Mucosa Treated by He Ne Laser Irradiation standard yarn size thickness, without the corresponding laser intelligence of motion state in broken yarn situation etc.The yarn information of the laser intelligence producing after the yarn generating when Ear Mucosa Treated by He Ne Laser Irradiation is actual and standard is inconsistent, and the yarn that explanation is produced in real time goes wrong.
