Abstract
The utility model discloses a kind of modified node method of ultrasonic transducer, comprise shell, piezoelectric chip, piezoelectric chip wire, sound-absorbing material, filler, inclination sensor and inclination sensor wire.Described piezoelectric chip is installed in the enclosure and is positioned at the position at top, the inner of piezoelectric chip wire is connected with piezoelectric chip, shell is stretched out in the outer end of piezoelectric chip wire, inclination sensor is installed in the enclosure and is positioned at the below of piezoelectric chip, inclination sensor wire the inner is connected with inclination sensor, shell is stretched out in the outer end of inclination sensor wire, and piezoelectric chip and inclination sensor wrap up by the filler be full of in shell.Because the utility model is provided with obliquity sensor, whether can there occurs inclination by perception container, main frame can carry out rejecting process, when the utility model is applied to fuel consume sensor to the ultrasound echo data measured when tilting, the data measured are more accurate, there will not be the measured value of mistake.
Description
Technical field
The utility model relates to detection field, particularly relates to a kind of modified node method of ultrasonic transducer.
Background technology
Because ultrasonic wave directive property is strong, energy ezpenditure is slow, and that propagates in media as well is distant, and thus ultrasonic wave is through being usually used in the measurement of distance, as rangefinder and fill level measuring device etc. can be realized by ultrasonic wave.The principle mandates ultrasonic wave of ultrasonic ranging impinges perpendicularly on medium face, and transducer sends ultrasonic wave, reflects at liquid-air boundary, and by receive MUT.By calculating the time difference sending and receive, liquid level can be calculated.When container run-off the straight, ultrasonic wave, when liquid-air boundary reflects, is not directly reflex to transducer, and is through chamber wall refraction, is just arrived by receive MUT.In this case, the distance calculated not is the vertical range between transducer and interface, is the measured value of mistake.In the practical application of ultrasonic wave fuel consume sensor, when vehicle run-off the straight, as on the slope, the liquid level now measured is likely just wrong.
Summary of the invention
The purpose of this utility model is to provide a kind of modified node method detecting data ultrasonic transducer more accurately.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of modified node method of ultrasonic transducer, comprises shell, piezoelectric chip, piezoelectric chip wire, sound-absorbing material, filler; Described piezoelectric chip is installed in the enclosure and is positioned at the position at top, the inner of piezoelectric chip wire is connected with piezoelectric chip, shell is stretched out in the outer end of piezoelectric chip wire, and sound-absorbing material is arranged between piezoelectric chip and inclination sensor, is full of filler in the enclosure; The utility model also comprises inclination sensor and inclination sensor wire; Described inclination sensor is installed in the enclosure and is positioned at the below of piezoelectric chip, inclination sensor wire the inner is connected with inclination sensor, shell is stretched out in the outer end of inclination sensor wire, and piezoelectric chip and inclination sensor wrap up by the filler be full of in shell.
After adopting such scheme, because the utility model adds obliquity sensor in traditional ultrasonic transducer, make whether can there occurs inclination by perception container while measurement, main frame can carry out rejecting process to the ultrasound echo data measured when tilting, when ultrasonic transducer of the present utility model is applied to fuel consume sensor, the data measured are more accurate, there will not be the measured value of mistake.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model;
Fig. 2 is the schematic diagram of the utility model when being applied to detection;
Fig. 3 is the schematic diagram that the utility model is in inclination when being applied to detection.
Detailed description of the invention
As shown in Figure 1, the utility model is a kind of modified node method of ultrasonic transducer, comprises shell 1, piezoelectric chip 2, piezoelectric chip wire 3, sound-absorbing material 4, inclination sensor 5, inclination sensor wire 6, filler 7.
Described piezoelectric chip 2 to be arranged in shell 1 and to be positioned at the position at top, the inner of piezoelectric chip wire 3 is connected with piezoelectric chip 2, shell 1 is stretched out in the outer end of piezoelectric chip wire 3, and sound-absorbing material 4 is arranged between piezoelectric chip 2 and inclination sensor 5, is full of filler 7 in shell 1.
Described inclination sensor 5 to be arranged in shell 1 and to be positioned at the below of piezoelectric chip 2, and inclination sensor 5 is fitted in the bottom surface of piezoelectric chip 2.Inclination sensor wire 6 the inner is connected with inclination sensor 5, and shell 1 is stretched out in the outer end of inclination sensor wire 6, and piezoelectric chip 2 and inclination sensor 5 wrap up by the filler 7 be full of in shell 1.
Operation principle of the present utility model:
As shown in Figure 2, the utility model transducer 10 sends ultrasonic wave, reflects at liquid-air boundary 20, and is received by transducer 10.Calculate the time difference sending and receive, can liquid level be calculated.When container 30 run-off the straight, as shown in Figure 3, ultrasonic wave, when liquid-air boundary 20 reflects, is not directly reflex to transducer 10, and is through the refraction of container 30 wall, is just received by transducer 10.In this case, the distance calculated not is the vertical range between transducer and interface, is the measured value of mistake.In the practical application of ultrasonic wave fuel consume sensor, when vehicle run-off the straight, as on the slope, the liquid level now measured is likely just wrong.Now, whether obliquity sensor 5 can there occurs inclination by perception container 30 while measurement, and main frame can carry out rejecting process to the ultrasound echo data measured when tilting, and the data of the measurement being are more accurate, there will not be the measured value of mistake.
Emphasis of the present utility model is just: increase an obliquity sensor.
The above, be only the utility model preferred embodiment, therefore can not limit with this scope that the utility model implements, the equivalence namely done according to the utility model claim and description change with modify, all should still belong in scope that the utility model patent contains.
