Description
Technical field
The utility model relates to tobacco purchase classification field, more specifically, relates to a kind of based on hyperacoustic tobacco leaf thickness detection apparatus.
Background technology
When tobacco purchase stands in purchase tobacco, because land for growing field crops tobacco leaves property is different, after modulation, quality is not identical yet, if quality mixes, use value must reduce, and causes the wasting of resources, and economic benefit reduces.Former cigarette is through repeatedly processing, and scientific formula just can be produced and meet that consumer requires, that style is different cigarette, and scientific formula completes on the basis of tobacco leaf grading, if high-grade Virginian-type cigarette is based on middle leaf.Tobacco leaf grading is conducive to transferring tobacco grower and produces the enthusiasm of sound tobacco, increases the income of tobacco grower, with time stage and price also for tobacco grower specifies the direction of leaf tobacco production.Reasonable classification is conducive to carrying out and reasonably develops the exploitation inferior quality tobacco leaf of tobacco leaf secondary product and tobacco leaf secondary product.Therefore, tobacco leaf grading during tobacco purchase has great importance.
GB2635-1992 gives the standard of cured tobacco leaf classification, and be divided into 42 grades, the parameter that tobacco leaf grading relates to is more, comprises all many-sides such as position, color, oil content, colourity, width, length, thickness, residual wound and breakage.Thickness is the important parameter of tobacco leaf grading, can reflect the quality of the quality of tobacco leaf.The measurement of current tobacco leaf thickness is generally stacked up by multiple tobacco leaf, by its thickness of kind of calliper.Owing to having space to exist unavoidably between every layer of tobacco leaf after tobacco leaf superposition, and the limited precision of slide calliper rule, there is comparatively big error when therefore the method measures tobacco leaf thickness, and measuring accuracy is low, speed is slow, efficiency is low, badly influences the progress of tobacco purchase.
Utility model content
The utility model overcomes that error described in above-mentioned prior art is large, precision is low, speed is slow, inefficient defect, provides that a kind of error is little, precision is high, speed is fast, efficiency is high based on hyperacoustic tobacco leaf thickness detection apparatus.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of based on hyperacoustic tobacco leaf thickness detection apparatus, comprise smooth support plate, ultrasonic transmitter, ultrasonic receiver, processor and display unit, described smooth support plate horizontal positioned, described ultrasonic transmitter and ultrasonic receiver are positioned at same level line and are arranged at directly over described smooth support plate, and described processor is electrically connected with ultrasonic transmitter, ultrasonic receiver and display unit respectively.
In the preferred scheme of one, described ultrasonic transmitter and ultrasonic receiver are integral type integrated morphology.
In the preferred scheme of one, described device also comprises constant temperature and pressure case, and described smooth support plate, ultrasonic transmitter, ultrasonic receiver and processor are arranged in constant temperature and pressure case, and described display unit is arranged at outside constant temperature and pressure case.Because hyperacoustic velocity of propagation can produce trickle change with the change of air pressure, temperature, the accuracy of measurement result can be improved under constant voltage, constant temperature, constant humidity condition.
In the preferred scheme of one, described processor adopts STC89C52 single-chip microcomputer.STC89C52 is a kind of low-power consumption, high-performance CMOS 8 8-digit microcontroller of STC Corporation's production, has 8K in-system programmable components flash storage.STC89C52 uses classical MCS-51 kernel, but has done the function that a lot of improvement makes chip have traditional 51 single-chip microcomputers not possess.On a single chip, have 8 dexterous bit CPUs and in-system programmable components Flash, height is flexible, the solution of super efficient for numerous embedded Control application system provides to make STC89C52, and it has cost feature little and low in energy consumption.
In the preferred scheme of one, described display unit adopts LCD1602 LCDs.LCD1602 is a kind of low cost dot matrix type Liquid Crystal Module being used for showing letter, numeral, symbol etc. specially, can show 16x02(16 row 2 row simultaneously) i.e. 32 characters.It is made up of dot character positions such as several 5X7 or 5X11, and each dot character position can show a character, has the interval of a some distance between every, often also has interval between row, serves the effect of character pitch and line space.
Compared with prior art, the beneficial effect of technical solutions of the utility model is: the utility model provides a kind of based on hyperacoustic tobacco leaf thickness detection apparatus, comprise smooth support plate, ultrasonic transmitter, ultrasonic receiver, processor and display unit, described smooth support plate horizontal positioned, described ultrasonic transmitter and ultrasonic receiver are positioned at same level line and are arranged at directly over described smooth support plate, and described processor is electrically connected with ultrasonic transmitter, ultrasonic receiver and display unit respectively.Ultrasonic transmitter launches ultrasound wave to smooth support plate, ultrasound wave is received by the first ultrasonic receiver after smooth support plate reflection, the speed of ultrasonic propagation is known, and therefore the processor Time Calculation ultrasonic transmitter that sends according to ultrasound wave and receive is to the distance h1 of smooth support plate; Be placed horizontally at by tobacco leaf to be measured on smooth support plate, in like manner record the distance h2 of ultrasonic transmitter to tobacco leaf to be measured, tobacco leaf thickness T is h1-h2, and processor is sent to display unit after calculating the thickness of tobacco leaf to be measured and shows; The utility model has relative to prior art the advantage that error is little, precision is high, speed is fast, efficiency is high.
