Description
Technical field
The present invention relates to tobacco purchase classification field, more specifically, relate to a kind of tobacco leaf thickness detection apparatus based on laser transmittance.
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.
Summary of the invention
The present invention overcomes that error described in above-mentioned prior art is large, precision is low, speed is slow, inefficient defect, provides the tobacco leaf thickness detection apparatus based on laser transmittance that a kind of error is little, precision is high, speed is fast, efficiency is high.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of tobacco leaf thickness detection apparatus based on laser transmittance, comprise black box, generating laser, photodetector, processor, memory module and display module, described generating laser and photodetector are arranged in black box, described display module is arranged at outside black box, described processor is electrically connected with generating laser, photodetector, memory module and display module respectively, and described memory module stores the corresponding relation of tobacco leaf thickness and laser transmittance.
In the preferred scheme of one, described memory module is integrated in described processor.Memory module is the internal storage of processor, simplifies the design of processor peripheral circuit.
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 module 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 discloses a kind of tobacco leaf thickness detection apparatus based on laser transmittance, comprises black box, generating laser, photodetector, processor, memory module and display module.During detection, tobacco leaf to be measured is placed in black box, the laser of laser transmitter projects is incident from the side of tobacco leaf to be measured, photodetector receives the laser through tobacco leaf to be measured from the opposite side of tobacco leaf to be measured, processor is according to the laser transmittance of incident laser and the Strength co-mputation tobacco leaf to be measured through tobacco leaf laser to be measured, and the corresponding relation searching tobacco leaf thickness that memory module stores and laser transmittance obtains the thickness of tobacco leaf to be measured.In black box, detect the interference can avoiding the light such as daylight, light, the utility model has relative to prior art the advantage that error is little, precision is high, speed is fast, efficiency is high.
