Abstract

The invention discloses an endoscope for executing sound wave detection and voiceprint comparison. The endoscope is characterized in that: the endoscope comprises a compliant cable, a handheld host and a pickup element; the handheld host comprises an analog-to-digital converter, a storage unit and a digital signal processor; the pickup element transmits collected sound waves to the handheld host; the sound waves are transited to digital signals by the analog-to-digital converter; and the digital signal processor which compares the digital signals with voiceprint data in the storage unit sends the comparison result to the display of the handheld host to display.

Description

Carry out the introscope of sonic detection and vocal print comparison

Technical field

The present invention relates to a kind of introscope, particularly relate to a kind of introscope of carrying out sonic detection and vocal print comparison.

Background technology

The development of introscope (endoscope) significantly promotes and penetrates the effect that object is observed its internal mechanism, and mostly endoscope apparatus early is that big monitor, light source, power supply and introscope form, and these a little equipment are all heaviness and bulky at that time; Through these effort in several years research and development; Can introscope equipment be contracted to hand-holdable and carry, and be widely used in each field, like industry and medical field; General doctor, architect, Electronics Engineer, the slip-stick artist of mechanism or technician can be by the images on the screen; Judge the problem that examined object is inner, medical application is like inspection UGI, large intestine etc., industrial use as check engine, turbine etc.

And general introscope only has the function that receives image at present, and does not have the function that receives sound, and therefore general introscope can't further judge whether examined object inside has damage through the sound; For example, when examined object is the engine of automobile, if when the operator can hear the noise sound that the engine blade produces; Can judge that engine is unusual; And then seek the problem part in detail, and for example during the human body respiratory tract, if when the operator can hear the noise sound that is produced when breathing; Can judge has foreign matter (like sputum) to block, the first aid action that the operator can be correlated with.

But above-mentioned situation must the operator has the ability to judge whether the sound that produces is the problem place, and difficulty is too high for general user, have the function that receives sound merely and can't make general user can be easily, convenient use.

Summary of the invention

Fundamental purpose of the present invention provides a kind of introscope of carrying out sonic detection and vocal print comparison, is used to solve the variety of issue that existing introscope produces when using.

A kind of introscope of carrying out sonic detection and vocal print comparison of the present invention comprises:

One pliability cable, the one of which end has a control module, is provided with several signal wires in the said pliability cable;

One hand-held main frame comprises an analog-digital converter, a storage element and a digital signal processor, and this storage unit stores has several vocal print data; And

One pick-up element is located on the said control module, can collect the sound wave of surrounding environment and be converted into a speech simulation signal, and be sent to said hand-held main frame through said signal wire;

Wherein, When this speech simulation signal is sent to said hand-held main frame; Via said analog-digital converter the speech simulation conversion of signals is become digital signal, and be sent to digital signal processor, digital signal processor promptly carries out the comparison of several vocal print data in digital signal and the storage element.

The introscope of execution tool sonic detection of the present invention and vocal print comparison has following advantage:

1. have that visor can receive the sound by pick-up element within the comparison of sonic detection and vocal print, improve by this introscope check examined object inside whether problematic correctness with reduce the error that detects.

2. the visor of having within the comparison of sonic detection and vocal print can receive by pick-up element and carry out the vocal print comparison behind the sound, so that a pair of testing result that should the sound to be provided, can help the user easily to use.

Below in conjunction with accompanying drawing structure of the present invention, principle and effect thereof are elaborated.

Embodiment

Fig. 1 has shown introscope one-piece construction of the present invention, and Fig. 2 has shown the circuit structure of the introscope of execution sonic detection of the present invention and vocal print comparison, and is as depicted in figs. 1 and 2; The present invention carries out the introscope that ripple detects and vocal print is compared and comprises: a pliability cable 1, one a hand-held main frame 2 and a sound pick up equipment 31; This pliability cable 1 is flexible, and various material capable of using adds with different levels thinks that coiled tubulose, one of which end have a control module 3; This control module 3 is provided with an image-finding element 32 and a plurality of light-emitting components 33; And be provided with several signal wires in this pliability cable 1, image-finding element 32 can be the CCD or the cmos sensor of configuration optical lens, in order to obtain image data; Light-emitting component 33 can be light emitting diode; Assist image-finding element 32 to obtain image data in order to throw a light, and the image data that image-finding element 32 produces can be sent to hand-held main frame 2 via those signal wires; Also be provided with a display 21, a key groups 22, two communication interface port (not shown) and a storage card slot (not shown) on should hand-held main frame 2, and key groups 22 also can transmit control signal by these signal wires.And hand-held main frame 2 inside also comprise an analog-digital converter 23, a storage element 24 and a digital signal processor 25; This storage element 24 stores several vocal print data; So-called vocal print data are digitizing, have the sound spectrum of high short arc, waveform, and the vocal print data that store; Be the sample sound of general FAQs, the sound of the engine failure of for example pre-recording in advance is used as vocal print data or the like; Utilization is installed in the pick-up element 31 on the control module 3; Collect the sound wave 4 of surrounding environment and convert the simulating signal of a sound into; Be sent to the analog-digital converter 23 of hand-held main frame 2 inside through signal wire; This analog-digital converter 23 is about to the simulating signal of sound, converts digitized digital signal to, and this digital signal just can be sent to the comparison of carrying out several vocal print data in digital signal and the storage element 24 in the digital signal processor 25; Sound waveform comparison like digital signal and vocal print data; Or be comparison of amplitude or the like, when comparison is found digital signal and vocal print data in the storage element 24 are had identical meeting, can judge easily that collected sound is the sound that belongs to which kind of fault, which kind of problem; And with the comparison result shows of corresponding this sound on the display 21 of hand-held main frame 2; Certainly when pick-up element 31 is collected the sound wave 4 of surrounding environment and is converted the simulating signal of a sound into, also can the simulating signal of this sound directly be played back through the loudspeaker on the hand-held main frame 2, the user can listen to the sound that loudspeaker spread out of; Judge directly whether examined object inside is unusual, and then seek the damage part in detail and repair; This pick-up element 31 specifically can be a microphone, and the structure of this microphone can be omni-directional microphone or unidirectivity microphone, and the present invention is not as limit.
