The online roll wind-up detection and alarm system based on machine vision is characterized by comprising an ARM (advanced RISC machine) controller (1), an image capture card (2), a trigger (3), a sound-light alarm module (4), a PLC (programmable logic controller) (5), a system reset module (6), a display module (7), a roll rotating machine (8), a crack positioning module (9), a roll speed detection module (10), a travel switch (11), a background processing module (12), a light source irradiation module (13), a to-be-detected region (14) and a CCD (charge-coupled device) industrial camera (15). Compared with the prior art, the online roll wind-up detection and alarm system has the advantages of simple structure, convenience in installation and debugging, high reliability, high measurement accuracy, low power consumption, easiness in popularization and promotion, convenience in maintenance, and the like.
Description
Technical field
The invention belongs to mechanical vision inspection technology field, in particular, belong to a kind of curling round the roll on-line checkingi warning system based on machine vision.
Background technology
In the end processing sequences of terylene short fiber; will through the 3rd drawing-off and nervous heat-setting section 2 important process links; owing to there is the pulling force inequality that each tow can bear, roller rotating speed surface temperature that is too fast or roller crosses high reason, often tow collaring can occur.In actual production process, if fail to deal with to curling round the roll in time.Just the reduction of roller damage and production efficiency will be caused.
At present, this problem of process has three kinds of methods both at home and abroad.The first, utilize the tow being wrapped in roller surface during curling round the roll to make travel switch produce mechanical shift, by displacement transducer, displacement signal is converted to electric signal, thus output alarm or stopping signal.The second, utilize opto-electronic receiver principle, by optical transmitting set battle array and the same side putting a face of optical receiver battle array, and place a light reflecting board in the opposing party relevant position.If generation curling round the roll, will inevitably produce crack in silk face, the light that optical transmitting set sends is obtained by optical receiver after reflecting plate, and then is converted to electric signal, produces alerting signal.3rd, camera is utilized the image of collection to be sent to video frequency collection card in PC through vision cable, then use image processing techniques to process the bitmap images that computing machine obtains, if detect the crack of one fixed width in bitmap images, then send alerting signal at once.
But owing to having a large amount of water vapour and Korrosionsmedium in forming machine, temperature and pressure is higher, and the fault of travel switch loose contact often can occur, photo-electric is again easily by the interference of site environment.Although video detection system can overcome the shortcoming of first two method, this system need in conjunction with PC, and structure is more complicated, and volume is comparatively large, safeguards relative difficulty.
Summary of the invention
The present invention, in order to effectively solve above technical matters, gives a kind of curling round the roll on-line checkingi warning system based on machine vision.
A kind of curling round the roll on-line checkingi warning system based on machine vision of the present invention, is characterized in that: comprise ARM controller, image pick-up card, trigger, sound and light alarm module, PLC, system reset module, display module, roller electric rotating machine, crack locating module, roller speed detection module, travel switch, background process module, light source irradiation module, region to be checked, CCD industrial camera; Wherein:
Described ARM controller respectively with described image pick-up card, described trigger, described sound and light alarm module, described PLC, described system reset module, described display module is connected, described image pick-up card respectively with described ARM controller, described background process module is connected, described background process module respectively with described image pick-up card, described light source irradiation module is connected, described light source irradiation module respectively with described background process module, described region to be checked is connected, described region to be checked respectively with described light source irradiation module, described CCD industrial camera is connected, described PLC respectively with described ARM controller, described roller electric rotating machine, described crack locating module, described roller speed detection module, described travel switch is connected.
The present invention is compared with prior art: have that system architecture is simple, installation and debugging convenient, system reliability is high, measuring accuracy is high, low in energy consumption, be easy to penetration and promotion, the advantage such as easy to maintenance.
