The growth of winter wheat processed, causes plant short and small, blade and Bao You little, when nitrogen nutrition is superfluous, and winter wheat branch can be caused excessive, covets
Green grass or young crops plays ripe.
The detection method of existing winter wheat nitrogen nutrition is detected typically by outward appearance, the processing of chemical detection, visual pattern
Technology is come what is completed, and these detections are typically sampling Detection, it is impossible to the whole detections of large area, on a large scale progress, it is impossible to cover
Whole wheatland.
With continuing to develop and image resolution continuous improvement for remote sensing platform, remote sensing technology is obtained in wheat detection field
To being widely applied, such as detection of wheat planting area detecting, growing way and yield estimation.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of winter wheat nitrogen nutrition remote sensing detection dress
Put, can be detected on a large scale, accuracy in detection is high, improve the fertilising efficiency of nitrogenous fertilizer.
The utility model provide a kind of winter wheat nitrogen nutrition telemetry unit, including remote sensing satellite, near-earth remote sensor,
Signal amplifier, signal transceiver, wave filter and data processor, the remote sensing satellite are messaging in the data processor, institute
State near-earth remote sensor and be messaging in signal amplifier, the signal amplifier is messaging in the signal transceiver, the signal transmitting and receiving
Device is messaging in the wave filter, and the wave filter is messaging in the data processor.
Further, in addition to temperature detector, the temperature detector is messaging in the data processor.
Further, in addition to moisture detector, the moisture detector is messaging in the data processor.
Further, data memory module, data processing module and data contrast module are provided with the data processor.
Further, the near-earth remote sensor is infrared transmitter.

By such scheme, the utility model at least has advantages below：Winter wheat nitrogen nutrition remote sensing of the present utility model
Detection means carries out long-time, large-scale remote sensing detection by remote sensing satellite to winter wheat, according to data processor to remote sensing
The image of satellite transmission is analyzed and processed, and judges whether winter wheat nitrogen nutrition is distant normal, if nitrogen nutrition is abnormal, by near
Ground remote sensor carries out remote sensing detection closely again, and the testing result of testing result and remote sensing satellite is contrasted, if
Comparing result is consistent, then winter wheat is handled accordingly in time according to testing result, because the nearest haze of China is tighter
Weight, the image of remote sensing satellite detection is not necessarily accurate, passes through the further detection of near-earth remote sensor, it is possible to increase detection is accurate
Degree, it is ensured that the fertilising efficiency and fertilization effect of nitrogenous fertilizer.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and being practiced according to the content of specification, with preferred embodiment of the present utility model and coordinate accompanying drawing detailed below
Describe in detail bright as after.
Brief description of the drawings
Fig. 1 is the block diagram of the utility model winter wheat nitrogen nutrition telemetry unit.
Embodiment
With reference to the accompanying drawings and examples, embodiment of the present utility model is described in further detail.Below
Embodiment is used to illustrate the utility model, but is not limited to scope of the present utility model.
Embodiment：A kind of winter wheat nitrogen nutrition telemetry unit, including remote sensing satellite 1, near-earth remote sensor 2, signal are put
Big device 3, signal transceiver 4, wave filter 5 and data processor 6, the remote sensing satellite is messaging in the data processor, described
Near-earth remote sensor is messaging in signal amplifier, and the signal amplifier is messaging in the signal transceiver, the signal transceiver
The wave filter is messaging in, the wave filter is messaging in the data processor.
Also include temperature detector, the temperature detector is messaging in the data processor.
Also include moisture detector, the moisture detector is messaging in the data processor.
Data memory module, data processing module and data contrast module are provided with the data processor.
The near-earth remote sensor is infrared transmitter.
The signal transceiver is infrared spectrum sensor.
The principle of the winter wheat nitrogen nutrition telemetry unit is：Material, can be in some certain waves under Electromagnetic Field
The absorption that section forms spectrum reflects the composition and structural information of material with reflection characteristic.Different crops possesses different spectrum
Reflection characteristic, same crop as environmental condition, production management measure, the difference of breeding time and N Nutrition and
It there is the difference of spectral characteristic.When crop but nitrogen, spectral reflection characteristic can change with a series of changes of blade.
Three band spectrum reflectivity such as green, red, near-infrared are all sensitive to the nitrogen content of plant.
The working method of the winter wheat nitrogen nutrition telemetry unit is：When carrying out long to winter wheat by remote sensing satellite
Between, large-scale remote sensing detection, analyzed and processed according to the image that data processor is transmitted to remote sensing satellite, judge winter wheat
Whether nitrogen nutrition is distant normal, if nitrogen nutrition is abnormal, carries out remote sensing detection closely again by near-earth remote sensor, and will
Testing result and the testing result of remote sensing satellite are contrasted, small to the winter in time according to testing result if comparing result is consistent
Wheat is handled accordingly, because the nearest haze of China is than more serious, and the image of remote sensing satellite detection is not necessarily accurate, by near
The further detection of ground remote sensor, utilizes the effect of signal amplifier and wave filter, it is possible to increase accuracy in detection, it is ensured that nitrogenous fertilizer
Fertilising efficiency and fertilization effect.
