Background technique
Tealeaves has the ecosystem characterization for liking warm moisture-proof, but be subject to low as a kind of important specialty economies crop in China
Temperature stress, the main growing area of tealeaves are located at the Subtropical hill mountain area on the south the Changjiang river, and region temperature when Winter-Spring replaces is more
Become, cold spell in later spring phenomenon often occurs, under usual climate condition, in lower atmosphere layer, temperature is generally reduced with the increase of height,
But in the cold spell in later spring time, earth's surface cools down due to radiating cooling, liftoff closer, and air cools faster, and upper layer air is by ground
Table influence it is weak, cooling slowly, occur temperature with the rising of height increased trend, i.e. temperature inversion.
When temperature inversion occurs, the cold tolerance of the tea shoot of sprouting is reduced, and tender shoots will receive slight jelly at 0 DEG C or so
Evil, also at -3 DEG C to 2 DEG C serious cold damage can occur for the strong breeding of frost resistance, by freeze injury tender shoots it is processed after, flavour is bitter,
Fragrance is low, and the early morning tea of serious cold damage cannot then pick, and causes biggish loss to agricultural economy.So the frost prevention for carrying out crop removes
Frost work is most important, and timely and accurately detecting frost and being formed is the primary factor for influencing frost prevention defrosting efficiency.

Specific embodiment
Following embodiment further illustrates the contents of the present invention, but should not be construed as limiting the invention.Without departing substantially from
In the case where essence of the present invention, to modification made by the method for the present invention, step or condition and replaces, belong to model of the invention
It encloses.
In order to solve the problems, such as that the manpower monitoring timely and effective property of frosting situation in the prior art is poor, the present invention discloses one kind
White sensor is visited in tea place, and specific structure refers to Fig. 1-2, is equipped with column 8 in 1 bottom of bracket of sensor, and the bracket 1 is by insulating
Heat-insulating material is made, the bracket 1 be it is I-shaped, by " " type two sub-stents fixation be spliced, each sub-stent is by upper
Two pieces of crossbeams of lower end and the stringer composition at middle part, the sub-stent inside on right side are detecting area, are pair inside the sub-stent in left side
According to area, outboard end is respectively equipped with one group of sleeve being longitudinally correspondingly arranged 2 in detecting area and check plot, and sleeve 2 includes upper bush
21 and lower sleeve 22, it is equipped with detection illumination lamp 3a in the upper bush 21 of detecting area, is equipped with detection in lower sleeve 22 with photosensitive
Resistance 5a is horizontally disposed with a piece of solidifying white net 4 between the upper bush 21 and lower sleeve 22 of detecting area, and the solidifying white net 4 is by heat conduction material
Material is made, and the thickness of solidifying frost net 4 is small and surface is distributed the sieve pores of several same apertures, and one piece is equipped in the middle part of the stringer of sub-stent
The inner end of horizontal fixed plate 7, the solidifying white net 4 is fixedly connected with the fixed plate 7 in detecting area, is equipped in fixed plate 7
One mounting hole is equipped with temperature sensor 6 in the mounting hole in detecting area；Control is equipped in the upper bush 21 of check plot
With control photo resistance 5b is equipped in illumination lamp 3b, lower sleeve 22, the inside of the sub-stent is hollow structure, for photosensitive
The wiring of the exit of resistance and illumination lamp.
The upper bush 21 is identical with the shape of lower sleeve 22, and monnolithic case is that funnel is cylindrical, the cylindricality of upper bush 21
End is fixedly connected with the end of upper end floor beam, and the post ends of lower sleeve 22 are fixedly connected with the end of lower end floor beam, wherein funnel
Shape sections inner side is polished with bloom, and surface is very bright.
The detection selects the visible lights such as LED light, energy-saving lamp or laser lamp with illumination lamp 3a and control illumination lamp 3b
Lamp.
Detection principle are as follows: when the temperature at the high canopy in tea place is lower than 0 degree, temperature sensor 6 provides feedback signal, control
End is so that illumination lamp starts, and detection illumination lamp 3a irradiates solidifying white net 4, due to factors such as the refraction index of frost and cladding thickness
Difference, in the case where the condition that frosts meets, frost can be accumulated in gradually on solidifying white net 4, will necessarily be slow through the light of solidifying white net 4
It is slowly dispersed into surrounding or is blocked, the variation of light reception intensity, detection utilizes its own semiconductor with photo resistance 5a
Photoelectric effect, resistance value change correspondingly: incident intensity, and resistance reduces, and incident light is weak, and resistance increases.
Solidifying white net is not set in check plot, illumination error is much smaller than threshold value, it might even be possible to ignore, by control photo resistance 5b
It is compared with the difference of photo resistance 5a with threshold value with detection, is judged as there is white formation if difference is greater than threshold value, exports low
Level is judged as frostless formation if difference is less than threshold value, exports high level.
Fig. 3 is the circuit design schematic diagram that white sensor is visited in tea place disclosed by the invention: when temperature sensor 6 detects tea
When temperature at the high canopy in garden is lower than 0 degree, output signal to close the switch, detection illumination lamp 3a and control illumination lamp 3b
It lights simultaneously, when gradually there is frost, the resistance value difference between 3a and 3b is gradually increased, and IC1 and IC2 are buffer amplifier, is disappeared respectively
Except detection circuit is to the detection interference of photo resistance 5a and control photo resistance 5b, while increasing VR1 potentiometer adjustment electricity
The input voltage of the discreteness of circuit component, IC2 rises with the increase of frost amount, and IC3 is differential amplifier, will be caused small
Voltage difference is amplified to OK range, and IC4 is comparator, and VR2 is the potentiometer of given threshold, by amplified difference and threshold value into
Row multilevel iudge, finally exports trigger signal, and buzzer prompt of sounding has frost.
Basic principles and main features and advantage of the invention have been shown and described above.But the foregoing is merely this hairs
Bright specific embodiment, technical characteristic of the invention are not limited thereto, and any those skilled in the art is not departing from this hair
The other embodiments obtained under bright technical solution should all cover within the scope of the patent of the present invention.
