Abstract
The utility model belongs to a detection control device for an industrial endoscope and provides a position detection indicator for a sight glass. The position detection indicator for the sight glass mainly consists of a 360-degree angular transducer, a signal comparison circuit, a signal interpretation cycling circuit, a signal drive circuit and a signal display circuit which are connected sequentially and electrically. The signal comparison circuit is a 12-way voltage comparator. When the 360-degree angular transducer rotates, the voltage comparator sequentially outputs high levels, a decoder in the signal interpretation cycling circuit outputs corresponding high level signals according to the combination situation of input signals. After the high level signals are driven by the signal drive circuit, a light-emitting diode (LED) indicator lamp is turned on and indicates a current angle at which the 360-degree angular transducer rotates. Therefore, the position detection indicator for the sight glass achieves the purpose of 360-degree position detection and accurate positioning and has wide application in the fields of industrial flaw detection and the like.

Background technology
Endoscope is a kind of multidisciplinary general instrument, and its function is to detect the crooked pipeline depths, can observe the position that can not look at straight, can in sealed cavity, observe interior spatial structure and state, can realize distant surveillance and operation.Industrial endoscope can be used for the inspection and the observation in the place that high temperature, poisonous, nuclear radiation and human eye can't observe directly; Be mainly used in automobile, aeromotor, pipeline, mechanical component etc.; Can realize Non-Destructive Testing need not dismantling or destroy under assembling and the equipment situation out of service, it is widely used in each department of modern core industry such as aviation, automobile, boats and ships, electric, chemical, electric power, coal gas, atomic energy, civil construction.Industrial endoscope also can couple with camera, video camera or robot calculator, forms photograph, shooting and image processing system, thereby carries out supervision, record, storage and the image analysis of visual field target.At present, in the industrial flaw detection field, the mode that generally adopts industrial endoscope to observe; But existing equipment does not dispose the structure of orientation indication, mainly judges the orientation of detection by experience in the past; Can not accurately locate directional bearing; The result judges inaccurate, on maintenance of products is improved, has the blind area phenomenon, causes defectives such as the product shaping rate is low, maintenance inconvenience.
Summary of the invention
In order to overcome the deficiency that existing industrial endoscope can not be indicated directional bearing, the utility model provides a kind of sight glass directional bearing indicator, can not only indicate directional bearing, and can realize the accurate location of 360 degree directional bearings.
The utility model solves the technical scheme that its technical matters adopted: a kind of sight glass directional bearing indicator; Mainly be electrically connected in proper order and form by 360 degree angular transducers, signal comparator circuit, signal interpretation cycling circuit, signal drive circuit and signal display circuit; Signal comparator circuit is connected to form by 12 road voltage comparators; Obtain a fixing voltage in the even dividing potential drop of the negative terminal of voltage comparator, the center tap of the positive termination 360 degree angular transducers of voltage comparator, a termination power VCC of 360 degree angular transducers; The 360 degree angular transducer other ends pass through resistance eutral grounding; When 360 degree angular transducers rotated, when the positive terminal voltage of voltage comparator was higher than negative terminal voltage, the output terminal of voltage comparator can be exported a high level; Because the high level of output terminal is the virtual high level of an open circuit, so will add and draw resistance.The input end of the code translator in the output terminal of voltage comparator and the signal interpretation cycling circuit is electrically connected; The output terminal of per four voltage comparators is connected with one 4 line-16 line code translator input end in the signal interpretation cycling circuit; Its effect is the signal-selectivity output signal according to input, and when rotating 360 degree angular transducers, voltage comparator can be exported high level successively; When the high level of these outputs is connected to the input end of corresponding code translator; Code translator can be according to the corresponding high level signal of combined situation output of input signal, and this signal is lighted the LED light emitting diode lamp after driving through signal drive circuit; And indicate 360 degree angular transducers current angles that turn to; Signal display circuit is connected to form by at least 12 LED light emitting diodes, and even distribution of LED light emitting diode and symmetrical ring are spent the pinpoint purpose of directional bearings around being arranged in circle thereby reached 360.
The beneficial effect of the utility model is: simple in structure, easy to operate, and can not only indicate directional bearing, and can realize the accurate location of 360 degree directional bearings, therefore, have purposes widely at aspects such as industrial flaw detection fields.
