Abstract
The invention relates to a rough-shape wire and cable on-line detection method, which is characterized in that a detection part is used for enabling a sample and a tested wire and cable to be in the same light curtain in a comparison mode, a light source is used for converting common light into a parallel light curtain through a lens to irradiate projections of the sample and the tested wire and cable to a photocell, and the light blocking area determines the voltage value of the photocell, so that the difference between the thickness of the tested wire and cable can be detected. The invention does not need to adjust circuit parameters of different cables, and realizes the concepts of universality, reliability, simple and convenient operation and high efficiency.
Description
Technical field
The present invention relates to a kind of online test method, especially a kind of coarse profile electric wire online test method.
Background technology
With sheath, coarse profile (containing non-round profile) isoelectric line cable profile more complicated, on-line measurement not yet has more common testing tool and opertaing device, and key is not have a kind of general method of testing.
Summary of the invention
The technical problem to be solved in the present invention is: propose a kind of coarse profile electric wire online test method, can measure the different of tested wire cable and sample thickness.
The technical solution adopted in the present invention is: a kind of coarse profile electric wire online test method, comprises the following steps:
1) selection standard sample and tested wire cable;
2) by above-mentioned both be positioned in same light curtain and carry out projection illumination;
3) judge the different of thickness that tested wire cable compares from sample according to the size of projection illumination area.
Step 2 of the present invention) in the light source that adopts be: the parallel light being converted to through lens by common non-parallel light; Described projection illumination is to photoelectricity receiving converter; The magnitude of voltage of described photoelectricity receiving converter changes according to the size of projected area; Described photoelectricity receiving converter is photoelectric cell.
The light source levels of the present invention upwards 45 degree elevations angle is irradiated.Receiving end alignment light source, avoids direct sunlight when installation, like this, because both are in same environment, light disturbs can be suppressed.
Determination methods in step 3) of the present invention is: the projected area of tested wire cable on photoelectric commutator is large, and light application ratio sample is few, and electric wire is partially thick; The projected area of tested wire cable on photoelectric commutator is little, and light application ratio sample is many, and electric wire is partially thin.
For different electric wires, as long as use guiding pinch roller by tested projection perpendicular light source, parallel lines are parallel to light source by tested parallel surface and just can detect.
The invention has the beneficial effects as follows: do not need different cables to carry out Circuit tuning parameter, realized general, reliable, easy and simple to handle, efficient theory.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is testing circuit schematic diagram of the present invention.
Embodiment
The present invention is further detailed explanation with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
The present invention by test section adopt manner of comparison by sample and tested wire cable in same light curtain, light source adopts common light to be converted to parallel optical screen through lens the projection illumination of sample and tested wire cable is arrived to photoelectric cell, because the area that is in the light is determining photronic magnitude of voltage, therefore can measure the different of tested wire cable and sample thickness.
Its principle of work and the course of work are as shown in Figure 1, IC1 input end connects 2 photoelectricity receiving converter parts, in addition R1C1 filtering (frequency is less than 40Hz), the impact of ambient light is suppressed, negative input end connects sample signal, positive input terminal connects tested wire cable signal, if the projected area of tested wire cable on photoelectricity receiving converter part large (cable is partially thick), light application ratio sample is few, input voltage is low, IC1 is output as " 0 ", if in the little situation of deviation, also have once in a while minority " 1 "---high voltage output, owing to having W1 current limliting between capacitor C 2 and IC1 output, as long as " 0 " is more than " 1 ", in final capacitor C 2, remain low-voltage, so, W1 and C2, R2 has certain integrating function.
C2 voltage compares respectively processing by IC2 and IC3, IC2 positive input terminal also can be stabilized to 0.5V with other pipe by 2AP9 constant voltage at 0.3V(), its negative input end is measured C2 voltage and is worth lower than this, is output as high level, is used to indicate " cable is partially thick " and also can be used as control signal.
If the projected area of tested wire cable on photoelectricity receiving converter part little (cable is partially thin), light application ratio sample is many, input voltage is high, IC1 is output as " 1 ", if in the little situation of deviation, also have once in a while minority " 0 " output, because capacitor C 2 has W1 current limliting between exporting with IC1, as long as " 1 ", more than " 0 ", remains high voltage in final capacitor C 1.
C2 voltage compares respectively processing by IC2 and IC3, and IC3 negative input end is by 2CP10 constant voltage at 0.7V, and its positive input terminal is measured C1 voltage and is worth higher than this, is output as high level, is used to indicate " cable is partially thin " and also can be used as control signal.
If C1 voltage in the above interval of setting, represents that " normally " IC2 and IC3 are low level.As the above analysis, do not need different cables to carry out Circuit tuning parameter, realized general target, adopt filtering and integration, can make to disturb and accidentalia impact reduction, with sample and the same light source measurement of tested cable, only need to use ordinary light source, reduced the problem that conversion brings.
Just the specific embodiment of the present invention of describing in above instructions, various not illustrating is construed as limiting flesh and blood of the present invention, person of an ordinary skill in the technical field read after instructions can to before described embodiment make an amendment or be out of shape, and do not deviate from essence of an invention and scope.
