All be less than non-overlapping place standard signal if there is all contrast signals of each angle, when six place's laser displacements passThe distance value contrast signal of sensor collection is all less than 100mm, and now judgement has expand tube risk. If now six place's contrast signal arithmeticMean value is 79mm, and 100mm-79mm=21mm has exceeded expand tube and reported to the police highly, triggers expand tube alarm command. If now six placesContrast signal arithmetic mean of instantaneous value is 74mm, and 100mm-74mm=26mm has exceeded expand tube and shut down height, triggers expand tube shutdown and refers toOrder.
All be greater than non-overlapping place standard signal if there is the multiple contrast signals in continuous angle, when 0 degree, 60 degree,The distance value contrast signal that 300 degree place laser displacement sensors collect is all greater than 100mm, and now judgement has the manage-style of collapsing danger. IfNow three place's contrast signal arithmetic mean of instantaneous values are 126mm, and 126mm-100mm=26mm has exceeded the pipe that collapses and reported to the police highly, triggersPipe alarm command collapses. If now three place's contrast signal arithmetic mean of instantaneous values are 136mm, 136mm-100mm=36mm, has exceeded and has collapsedPipe is shut down height, triggers the pipe halt instruction that collapses.
Be less than non-overlapping place standard signal if there is the single contrast signal of non-positive upper angle, and be less than or equal to adhesive tape limitWhen the former tape edge lap-joint standard signal at edge lap-joint standard signal or the adjacent angle of this angle place disappears, this example exists60 degree or the distance value that collects of the single place's laser displacement sensor of 300 degree are less than 100mm, and while being less than or equal to 85mm, orThe distance value that person 60 spends or the single place's laser displacement sensor of 300 degree collects is less than 100mm, 0 degree place virgin rubber band edge simultaneouslyWhen edge lap-joint standard signal has disappeared, now judgement has torsion risk. If angle information is herein 60 degree or 300 degree,Trigger and reverse alarm command. If angle information is herein when 120 degree or 240 are spent or even 180 spend, triggers torsion shutdown and refer toOrder.
When multibreak installation, on monitoring software, multibreak adhesive tape ruuning situation will be shown in real time, whole piece adhesive tape can be drawnTorsion situation schematic diagram, expand tube situation schematic diagram, the pipe situation of collapsing schematic diagram. The present invention can be circular pipe belt type conveyer operation peopleMember provides true and reliable adhesive tape service data, reduces to greatest extent potential safety hazard.
Below by reference to the accompanying drawings the specific embodiment of the present invention is described in detail, but the present invention is not limited to above-mentioned realityExecute mode, any amendment of making within all spirit in this practicality invention and principle, be equal to and replace and improvement etc., all should compriseWithin the protection domain of this practicality invention.
