Embodiment
Circuit of the present invention is formed referring to Fig. 2, and its principle of work is that driving pulse is not by the repeat its transmission of equipment by certain frequency constant duration itself in this equipment, receives then and handles; But produce driving pulse according to moving of probe, along with moving of probe, the linkage that is connected with probe can provide physical displacement that the physical location movable signal of probe equally spaced is provided to equipment, equipment produces driving pulse according to movable signal, and then the generation ultrasound wave, import tested object into through coupling, receive the ultrasonic echo signal Processing, just equally distributed ultrasound wave sound ray be can in tested object, produce, and then distortionless Type B scanning and the scanning of C type realized.Physical displacement in the described probe equally spaced provides the physical location movable signal generating means of probe can select the mouse or the homemade location mobile device of computer peripheral equipment for use to equipment, conversion and change by its mode of operation are easy to realize, so be easy to be used in the probe linkage of the present invention.The mouse of described computer peripheral equipment comprises a kind of in two kinds of mechanical photo-electric or the laser sensor formulas.
Under working method of the present invention, along with moving of probe, produce the probe movable signal and pass to control/processing unit, control/processing unit is to emission/receiving circuit transponder pulse, emission/receiving circuit produces the high pressure driving pulse and gives probe, probe produces ultrasound wave, import tested object into through coupling, ultrasound wave runs into different media and produces echo, probe reception echo is transformed into electric impulse signal and sends receiving circuit to, amplify or decay sends control/processing unit to and handles through analog amplify circuit, send into display then and show with corresponding form.Just can obtain the information of object to be detected inside according to the figure that shows, and then can judge in interior of articles whether defectiveness or focus.
The present invention can be referring to Fig. 3 with a specific embodiment of the mechanical-physical position encoder device that code wheel and photoelectric sensor constitute.Code wheel 2 peripheries are provided with the counting open-work, and the code wheel vicinity of corresponding counting open-work is provided with photoelectric sensor 3, and code wheel 2 is fixed on the housing by axle 11.A steamboat 4 and the coaxial setting of described code wheel are arranged, this steamboat 4 and gear wheel 5 engagements, this gear wheel 5 and steamboat 8 engagements that detect road wheel 9 coaxial settings detect road wheel 9 and gear wheel 5 and are fixed on the housing 1 by stationary shaft 6,10 respectively.The bottom part of described detection driving wheel 9 is exposed housing 1.The trigger pulse input end of the control/processing unit in the circuit board 12 in the output terminal of described photoelectric sensor 3 and the housing 1 is connected.The lower end is provided with ultrasonic emitting receiving transducer 7 in housing 1.
In the present embodiment, because only need be,, promptly use one to deceive code wheel and a photoelectric sensor gets final product therefore as long as the movable signal of the probe forward-reverse of a direction with the simulated line probe work of single probe or with the work of line probe emulation linear transducer array.Utilize nylon gear or instrument gears at a certain distance ratio of pulse length to the total cycle length drive code wheel and rotate and (, produce 200 pulses as 100 millimeters.Promptly whenever move 0.5 millimeter and just produce a pulse), the rotation of code wheel will make the output terminal of photoelectric sensor produce pulse, so just the linear distance that rotor wheel is rotated (i.e. the mobile distance of probe) information is transferred to the control/processing unit of defect-detecting equipment with the form of pulse, the direction that moves is transferred to control/processing unit (as to advance be low level, retreats to be high level) with the form of level.The stepping that probe moves determines that according to non-destructive testing standard it is demanding to detect resolution, adopts the smaller mobile stepping of probe.Otherwise, adopt bigger probe stepping.Because it all is equidistant through interlock generation step-by-step impulse that each of probe is advanced step by step, control/processing unit is launched driving pulse according to the forward position control radiating circuit of detected step-by-step impulse to probe, and the ultrasound wave sound ray that each emission comes in workpiece is exactly equally spaced like this.The echoed signal of these sound rays is depicted as B sweeps figure and has just realized the Type B scanning of workpiece is detected.And on a line you how mobile probe can not produce the phenomenon that B sweeps the figure distortion.This is because the generation of pulse ultrasonic wave each time only has relation with the step distance that probe moves, and it doesn't matter with the speed that moves, and therefore can realize that easily B sweeps detection with the arbitrary speed mobile probe.
In like manner, utilize this method to connect the line probe of medical supersonic, can realize easily the C type scanning of human body is detected.
Of the present invention based on laser sensor, the specific embodiment of the position encoded pulse generating device of formation can be referring to Fig. 4.Among Fig. 4, the following detection faces of housing 1 has a light hole, and the housing 1 that is arranged in the light hole place is fixed with an optical mouse device 14 (computer mouse).Described ultrasonic probe 7 is fixed on the detection faces of housing 1.
Described optical mouse device 14 and ultrasonic probe 7 are connected with control/processing unit in the housing interior circuit board 12 by line.
Described control/processing unit is to be made of traditional ultrasound wave control/processing unit, and it has and receives ultrasound echo signal and carry out two dimension or function that 3-D view is handled and the function of trigger pip is provided for probe emission driving pulse.In the present invention, control/processing unit is to launch driving pulse according to the forward position control radiating circuit of detected step-by-step impulse to probe, or according to the communications protocol (communications protocol of computer mouse) of optical mouse at each grid place, the pulse of control radiating circuit emission incentive probe.
In this example, because need the work of emulation linear transducer array, therefore need the probe movable signal of both direction on the planimetric coordinates.Utilize the reasonable optical mouse of quality on the market, after the dismounting, again be assembled into together with a ultrasonic probe, the communications protocol of mouse (or driver) is ready-made, determine that mouse whenever moves 0.5 millimeter and (also can select other size on horizontal ordinate and ordinate, according to detecting the resolution that requires) be exactly a grid, just being equivalent to the detection faces of object to be detected all is to be divided into grid by 0.5 millimeter with horizontal ordinate and ordinate.Like this along with the mouse moving of being with ultrasonic probe, control/the processing unit of ultrasound examination equipment is just controlled the pulse of radiating circuit emission incentive probe at each grid place according to probe, no matter mouse in computer is popped one's head in and where is moved to like this, control/the processing unit of checkout equipment is all clear, so long as on grid, just control radiating circuit emission driving pulse, control/processing unit deals the ultrasonic echo signal and is presented at the three-dimensional picture that has just formed an interior of articles on the screen by three-dimensional picture, also just realized the C type of object is detected.The unit step distance that probe moves requires to determine that according to detecting it is demanding to detect resolution, adopts smaller grid.Otherwise, adopt bigger grid.Because grid all is equally spaced, the ultrasound wave sound ray that each emission comes in workpiece is equally spaced all just like this, thereby any distortion phenomenon can not occur.This is because the generation of pulse ultrasonic wave each time only has relation with the position that probe moves, and it doesn't matter with the speed that moves, therefore with arbitrary speed clocklike mobile probe just can realize easily that the C type sweeps detection.
