Abstract
The utility model provides a watermelon maturity detection device is by square stainless steel hollow long box, sucking disc, strike module, sound wave collection module, sound wave processing module, microprocessor, LED display screen, switch and starting switch and constitute, it is terminal that the sucking disc is fixed in hollow long box, and open at its center has the hole, reducible external sound interference of waves, it is located the central hole department of sucking disc and rather than seamless connection, can strikes the watermelon and produce the sound wave with this to strike the module, the sound wave collection module depend on on strikeing the module for the produced sound wave data of module are strikeed and with sound wave data transfer to sound wave processing module to the collection, it is inside that sound wave processing module is located hollow long box for carry out the analysis to the sound wave data and judge with this whether ripe the watermelon is, microprocessor is inside attached to hollow long box for control switch, starting switch and LED display screen, the LED display screen is located hollow long box surface for show whether ripe the watermelon is. The utility model discloses simple structure, convenient and reliable can detect the watermelon maturity on high -efficient ground.
Description
Technical field
The utility model relates to a kind of Watermelon Maturity pick-up unit, relates generally to a kind of simple, convenient and reliable, can efficiently and accurately to the device that Watermelon Maturity detects.
Background technology
Judging in Watermelon Maturity at present, people have accumulated rich experience, such as " calculate growth period ", " observation formalness ", non-destructive methods such as " touch, clap, press, hear ", for consumer provides ripe watermelon to serve key effect, but these methods depend on supervisor's factors such as personal experience, be difficult to hold, therefore, scientifically, objectively nondestructive test carried out to watermelon and become and be even more important.
Summary of the invention
The technical solution of the utility model is: a kind of Watermelon Maturity pick-up unit, by a hollow long box of square stainless steel, sucker, knocks module, sound collecting module, sonicated module, microprocessor, LED display, power switch and starting switch and forms; Described sucker is fixed on hollow long box end, and its center has hole, can reduce the interference of external sound wave; Described knock module be positioned at sucker center hole place and with its seamless link, can knock watermelon and produce sound wave with this; Described sound collecting module is attached to knocks in module, knocks sonic data that module produces for gathering and sonic data is sent to sonicated module; It is inner that described sonicated module is positioned at hollow long box, judges that whether watermelon is ripe for analyzing sonic data with this; Described microprocessor is attached to the inside of hollow long box, for controlling power switch, starting switch and LED display; Whether described LED display is positioned at the surface of hollow long box, ripe for showing watermelon.The utility model structure is simple, convenient and reliable, can detect Watermelon Maturity efficiently.
Described sucker is used for isolated extraneous interference sound wave, can reduce or remove interference during sound collecting module acquires sound wave, for sonicated module provides Noise sonic data that is few or not Noise.
Described microprocessor is made up of STC89C58RD+ chip and peripheral circuit thereof, for controlling power switch, starting switch and LED display; Whether described LED display is for showing watermelon maturation, and ripe BG screen, prematurity is azarin screen then.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is schematic diagram of the present utility model.
In FIG, the 1. hollow long box of stainless steel, 2. sucker, 3. knocks module, 4. sound collecting module, 5. sonicated module, 6. microprocessor, 7.LED display screen, 8. power switch, 9. starting switch.
Embodiment
With reference to Fig. 1, a kind of Watermelon Maturity pick-up unit, by a hollow long box 1 of square stainless steel, sucker 2, knocks module 3, sound collecting module 4, sonicated module 5, microprocessor 6, LED display 7, power switch 8 and starting switch 9 and forms; Described sucker 2 is fixed on the end of hollow long box 1, and its center has hole, can reduce the interference of external sound wave; Described knock module 3 be positioned at sucker 2 center hole place and with its seamless link, can knock watermelon and produce sound wave with this; Described sound collecting module 4 is attached to knocks in module 3, knocks sonic data that module 3 produces for gathering and sonic data is sent to sonicated module 5; It is inner that described sonicated module 5 is positioned at hollow long box 1, judges that whether watermelon is ripe for analyzing sonic data with this; It is inner that described microprocessor 6 is attached to hollow long box 1, for controlling power switch 8, starting switch 9 and LED display 7; Whether described LED display 7 is positioned at hollow long box 1 surface, ripe for showing watermelon.
The course of work of the present utility model is as follows: first, grasps the handle on the right side of the hollow long box 1 of stainless steel, clicks power switch 8, thus starts power supply; Then sucker 2 is close to watermelon, makes sucker 2 mask external disturbance; Then click starting switch 9, thus start successively and knock module 3, sound collecting module 4 and sound wave processing module 5 and carry out work, complete the generation of sound wave, acquisition and processing, thus realize the detection to Watermelon Maturity; The testing result of Watermelon Maturity is sent to microprocessor 6, and shows in LED display 7; Last microprocessor 6 pairs of power switches 8, starting switch 9 reset, and make to knock module 3, sound collecting module 4 and sound wave processing module 5 and quit work, power supply is closed immediately.Like this, just complete once the detection of complete Watermelon Maturity, pluck watermelon for subsequent mechanical equipment and the foundation of whether plucking is provided.
