Detailed description of the invention
As illustrated in fig. 1 and 2, a kind of portable fruit maturity checkout gear, comprises data analysis module 2, the first spring 3, the first bolt 4, frame 5, piston 6, trigger 10, the second spring 11, wedge-shaped catch 12, impact bar 13, backstay 14, microphone 15.
Described frame 5 has first passage, second channel and the slideway that is connected first passage and second channel, the diameter of described first passage and second channel is all less than the diameter of slideway, impact bar 13 is positioned at first passage, the length of impact bar 13 is greater than the length of first passage, the first spring 4 is positioned at second channel, and the natural length of the first spring 4 (not receiving the length under any active force) is greater than the length of second channel, the first bolt 4 is connected with the end thread of second channel, for control the maximum compression length of the first spring 4 by the degree of depth that regulates precession frame 5 right-hand member holes, thereby control the maximum elastic force that the first spring 4 acts on piston 6. described piston 6 is arranged in slideway, and one end of piston 6 is connected with impact bar 13, and the other end is connected with the first spring 3.
Described slideway below has the groove being connected with slideway, and the lower end of described wedge-shaped catch 12 is connected with the bottom of groove by the second spring 11, and upper end extend in slideway; The wedge inclined-plane of described wedge-shaped catch 12 is towards impact bar 13; In the time that piston 6 is positioned at the rear side of wedge-shaped catch 12, wedge-shaped catch 12 blocks piston 6 and moves forward, and in the time that piston 6 is positioned at the front side of wedge-shaped catch 12, piston 6 can be pressed into wedge-shaped catch 12 in groove by wedge inclined-plane, thereby moves to the rear side of wedge-shaped catch 12. Trigger 10 generally comprises trigger end, rotates end, acts on end, and rotation end is hinged in frame 5 and (in figure, is undertaken hinged by connecting axle 7); What pull for mobile phone is trigger end, the other end, and effect end is hinged with wedge-shaped catch 12, pulls the trigger end of trigger 10 by finger, can hold by effect wedge-shaped catch 12 is moved down; Described microphone 15 is fixed on (in figure, microphone 15 is fixed in frame 5 by microphone holder 1) in frame 5, and is connected with data analysis module 2.
Microphone 15 is generally fixed on the front end of frame 5. Can also comprise backstay 14, be fixed on the front end of frame 5, for detection of time testee location, ensure that each condition of measuring is identical.
For convenience of operation, said apparatus can also arrange handle 9, and described frame 5 is connected by the second bolt 8 with handle 9.
Due in the time that maturity detects, need the qualitative data of fruit, therefore, this device can also comprise electronic scale, electronic scale is connected with data analysis module 2.
The common technology means that are this area according to the maturity of the acoustic signals gathering and quality acquisition fruit, are specially: data analysis module 2, for the acoustic signals collecting, carries out filtering. Then Fast Fourier Transform (FFT), extracts the second resonant frequency, then in conjunction with the quality of fruit, can calculate the fruit maturity situation that analyzes. Therefore, the data analysis module 2 in the utility model is only realized simple logical operation, and this module can be buied from market, for example, and VibPilot vibration control and dynamic signal acquisition analyzer (m+p international corporation, Germany); Or the data collection and analysis instrument that adopts the people such as D.C.Slaughter to adopt.
In the time that reality detects fruit maturity, first fruit to be measured is placed on electronic scale, obtain the qualitative data m of fruit, and be entered in data analysis module 2; If while thering is no electronic scale, qualitative data m manually can be entered in data analysis module 2.
Then the impact bar of this device 13 is aimed to the position, equator of fruit, the fixed range keeping between this device and detected target by backstay 14, cocking 10, trigger 10 is rotated to an angle, under the effect of trigger 10, wedge-shaped catch 12 moves down and compresses the second spring 11, final wedge-shaped catch 12 upper ends are left slideway completely, no longer piston 6 is had to barrier effect, piston 6 is under the effect of the first spring 3, move forward, promote impact bar 13, impact bar 13 moves forward, clash into fruit, make fruit vibration sounding, at this moment microphone 15 gathers sound, data analysis module 2 is for the sound collecting, carry out filtering. then Fast Fourier Transform (FFT), extracts the second resonant frequency f.
Data analysis module 2, by simple logical operation, can calculate the fruit maturity situation that analyzes.
In the time preparing to sample for the second time, manually the impact bar stretching out 13 is advanced in device, when moving inward, piston 6 wedge-shaped catch 12 can be pressed into glide path, in the time that piston 6 enters wedge-shaped catch 12 right-hand member completely, wedge-shaped catch 12 enters the slideway at piston 6 places under the effect of the second spring 11, and piston 6 is stopped.
