Abstract

The present invention relates to an on-line measuring system which can be used for measuring the thicknesses of various plates with smooth and clean surfaces in the process of movement, particularly to an on-line accurate measuring and monitoring system which can be used for measuring the thicknesses of the plates which can be influenced by environment and temperature, can move and are provided with surfaces which can not be pressed. A marking block which is additionally provided is measured by a laser probe in each stroke to achieve the purpose of eliminating the influence on the structural deformation by temperature. A plate thickness signal, a temperature compensating block thickness signal and a bracket stroke position signal which are measured by a laser sensor pass through a signal conditioning circuit to be conveyed into an industrial control computer, the signals are processed by the industrial control computer, and the plate thicknesses are monitored by the industrial control computer in a real-time way; accurate thickness signals can also be returned to an instrument on the spot to be visually displayed.

Description

A kind of on-line monitoring system that is used to measure thickness of clean-surface panel
Technical field
The present invention relates to have the on-line measurement of all kinds of sheet materials its thickness in moving of smooth finish surface, particularly a kind of measure influenced by ambient temperature, have beat, the online accurate measurement of bright and clean its thickness of sheet material that the surface can not pressurized and the structure of monitoring system.
Background technology
Present thickness measure can simply be divided into static measurement and kinetic measurement.The static measurement precision is higher, relevant both at home and abroad surveying instrument instrument is more, this quasi-instrument generally is used for offline mode, many restrictions are arranged in the use, thickness, measured body as measured body must be for being in non-motion state etc. with a kind of metallic matrix, measured body, it generally is used to measure nonferromagnetic coating, coating on the ferromagnetics metallic matrix, or measures the insulating coating on the non-ferromagnetic matter metallic matrix.
For kinetic measurement, because the complicacy (vibration, temperature etc.) of operating mode and the diversity of measurand, manual measurement is still main means at present.Also there is deficiency in the on-line dynamic measurement of sheet metal thickness: when accurately measuring to the working condition requirement height, as the flatness of plate, environment temperature etc.; With strong points, versatility is poor; Not constituting the accurate measurement of collection, status monitoring and data management as yet is the system of one.
Summary of the invention
At problems of the prior art, the present invention aims to provide a kind of to all kinds of sheet materials with smooth finish surface (metal, nonmetal or compound substance etc.) online accurate measurement of its thickness in moving, and makes up the sheet metal thickness on-line condition monitoring device lower to environmental requirement, that versatility is stronger.
Purpose of the present invention is finished by following technical solution: this on-Line Monitor Device that is used to measure thickness of clean-surface panel, comprise laser sensor and signal processing apparatus, sensor exists in pairs, respectively data are passed to signal processing apparatus by cable, calculate sheet metal thickness to be measured by signal processing apparatus; The sensor mounted in pairs is in relevant position, " U " shape support two ends, and " U " shape support can be pressed certain regular motion by control; Sheet material to be measured is positioned at " U " shape rack groove centre position, does perpendicular to plane, " U " shape support place and passes through motion; At sheet material to be measured a temperature compensation block has been installed on the elongated surfaces of " U " shape support, temperature compensation block is positioned on " U " type support sheet material elongated surfaces to be measured, by in the sensor each run to the measurement of temperature compensation block, reach and eliminate the purpose of temperature the malformation influence.
Above-mentioned " U " type support is by travel mechanism's controlled motion, and travel mechanism comprises equipment such as nut, guide rail, leading screw, stepper motor; Above-mentioned " U " type support is fixed by nut; Above-mentioned stepper motor rotates by the control leading screw and drives nut, and " U " type support is slided on the guide rail direction.
Above-mentioned " U " type support can make sensor move to outside sheet material to be measured and the temperature compensation block outer side edges by the movement travel of travel mechanism's control.
Above-mentioned signal processing apparatus comprises, signal conditioning circuit, industrial computer, field instrument; Contain graphical Survey Software program function module in the industrial computer, can distinguish sheet material and compensation block by programmed control.
Compared with prior art, should be by " U " type support and Design of numerical control (NC) system, realization vertically reaches the measurement of the one-tenth-value thickness 1/10 of horizontal multiple spot (or arbitrfary point) to mobile sheet material, probe is the laser sensor of a pair of non-cpntact measurement, because support stroke mode is selectable, dirigibility is strong, the fluctuation up and down among a small circle of tested sheet material does not influence the laser sensor measuring accuracy, and undulate quantity can be installed nip rolls by front and back greatly and reduced, therefore, tested sheet material is so long as have up and down smooth finish surface and just can measure, measurand even can be non-clear films material has satisfied the measurement of multiple material thickness, and applicable surface is wider.
By in the laser probe each run to the measurement of the mark piece of extra setting, reach and eliminate the purpose of temperature the malformation influence.What system had the differentiation measurement is the sheet material or the ability of compensation block, industrial computer all can obtain the actual pitch information of two probes by the thickness of measuring temperature compensation block in the each run, pitch information becomes the basis of calculation in the one stroke of back, when environment temperature causes the little distortion of mechanism, the basis of calculation can in time be revised, and like this, has just eliminated the influence of temperature to measuring accuracy, satisfied than under the severe temperature environment, to the accurate measurement of sheet metal thickness.
Measured thickness of slab signal, temperature compensation block thickness signal and the support travel position signal of laser sensor sent into industrial computer behind signal conditioning circuit, the signal Processing of finishing industrial computer just also realizes the real-time monitoring to thickness of slab, and accurate thickness signal also can return field instrument and show intuitively.Monitoring system is based on the LabVIEW platform development, makes full use of the LabVIEW advantage that develops software, and has functions such as parameter setting, rod figure demonstration, overproof warning, data analysis and management.Native system has satisfied the online accurate measurement of thickness, status monitoring and the incorporate requirement of data management.Have advantages such as friendly, the system cost of the credibility of convenience, monitoring result of real time of data acquisition, reliability of system operation, overproof accuracy of the forecast, module combinations and man-machine interface be lower.
