Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of crop information collection, and in particular to a meteorological environment parameter and spectrum synchronous measurement system and method. Background Art
[0002] The meteorological environment plays a decisive role in the growth process of crops. As the meteorological environment changes, crops themselves will generally make adaptive adjustments. However, it is difficult for vegetation to adapt to meteorological changes under abnormal conditions, which often causes major production disasters.
[0003] On the one hand, mastering real-time meteorological information plays a key guiding role in timely human intervention. Meteorological stations can well solve the problem of real-time grasp of meteorological information in the crop production environment. However, if crops want to grow better, have higher yields and better quality, it is difficult to meet actual production needs by relying solely on meteorological factors under natural conditions as technical support.
[0004] On the other hand, the use of spectrum to timely monitor the physiological and ecological information of crops, by monitoring the changes in crop physiological and ecological indicators under different water and fertilizer stress environments, and jointly analyzing them with the final harvest indicators, the optimal water and fertilizer stress conditions can be determined, so that the best water and fertilizer management measures can be obtained by monitoring the spectral information of crops in different growth periods. Multispectral equipment can efficiently monitor the spectral bands that respond to water and fertilizer deficiency in different crops, and because the data is more targeted, the data volume is smaller and more efficient analysis value.
[0005] However, whether it is through weather stations or multispectral equipment alone to guide crop production management, it is not enough to support the efficient management of crop production. Due to the high cost and the difficulty in synchronously collecting crop environmental parameters and spectral parameter information, the accuracy of the crop growth status analysis model is affected, and it is difficult to meet the high-precision decision-making model requirements in production management.
[0006] In summary, in order to meet the requirements of synchronous monitoring of crop growth environment and its own physiological and ecological information in unmanned outdoor environments, and to achieve the goal of efficient water and fertilizer control of crops in a more efficient data integration method, a system that can monitor both meteorological information and crop canopy spectral information is urgently needed.

DETAILED DESCRIPTION
[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0029] In the prior art, guidance for crop production management is often based unilaterally on meteorological data obtained by weather stations or unilaterally on spectral data of tested crops collected by multi-spectral equipment to assist in crop production management. However, the cost of detecting the two types of data separately is relatively high, and it is also difficult to synchronize the information between the two, resulting in large analysis errors and low accuracy. In order to synchronously monitor the crop growth environment and its own physiological and ecological information, and to achieve the goal of efficient water and fertilizer control for crops in a more efficient data integration manner, an embodiment of the present invention provides a meteorological environment parameter and spectral synchronous measurement system, such as Figure 1 As shown, it includes but is not limited to: a meteorological environment detection device 1, a multi-band spectral sensor 2 and a data acquisition and analysis processor 3; wherein the meteorological environment detection device 1 and the multi-band spectral sensor 2 are respectively communicated with the data acquisition and analysis processor 3; the data acquisition and analysis processor is used to synchronously collect and analyze the meteorological environment data and spectral parameter information of the tested crops; the meteorological environment data is obtained by the meteorological environment detection device 1, and the spectral parameter information is obtained by the multi-band spectral sensor 2.
[0030] Specifically, the meteorological environment parameter and spectrum synchronous measurement system provided by the embodiment of the present invention not only integrates the data acquisition and analysis processor 3, the meteorological environment detection device 1, and the multi-band spectral sensor 2 in the same system in terms of hardware composition, but the key is to be able to control the meteorological environment detection device 1 and the multi-band spectral sensor 2 to collect synchronous data through the data acquisition and analysis processor 3, and perform data integration processing on the acquired synchronous data, thereby effectively improving the accuracy of the analysis of the current state of the crops to be measured, and more accurately providing production management guidance for the crops to be measured.
[0031] Among them, the meteorological environment detection device is mainly used to detect and obtain the current meteorological information of the environment in which the tested crops are located, such as: environmental temperature and humidity, light intensity, rainfall, atmospheric pressure, wind direction and speed, and other parameters that affect the growth of crops.
[0032] Among them, the multi-band spectral sensor is mainly used to detect and obtain crop spectral parameter information such as the emitted and reflected light energy of different spectral bands of the tested crop at the same time. Further, as an optional embodiment, the spectrum obtained in each different band can be assigned RGB color respectively to obtain a color image. For example, R, G, and B are assigned spectral information of the three bands of R, G, and B respectively, and the synthesis will obtain a simulated true color image. Then analyze it to obtain the internal physiological and ecological information of the tested crop.
[0033] Among them, the data acquisition and analysis processor 3 can communicate with the meteorological environment detection device 1 and the multi-band spectral sensor 2 respectively by: a wired connection based on a serial port (such as a PLC serial port, RS 485 serial port, etc.), or a wireless transmission connection (such as a Bluetooth connection, etc.), which is not specifically limited in the embodiments of the present invention.
[0034] Furthermore, the data acquisition and analysis processor 1 provided in the embodiment of the present invention may also include a timing controller for periodically sending data acquisition instructions to the meteorological environment detection device 2 and the multi-band spectral sensor 3 to control them to sample corresponding data.
[0035] Furthermore, the data acquisition and analysis processor 1 may also include a data receiving and storage unit for receiving meteorological environment data and spectral parameter information, and packaging and storing the two sets of data after synchronizing them in time.
[0036] Furthermore, the data acquisition and analysis processor 1 provided in the embodiment of the present invention may also include a data processing unit to analyze the synchronized meteorological environment data and spectral parameter information in real time to obtain the current meteorological information of the environment in which the tested crop is located and the crop spectral parameter information. For example, a meteorological map and a spectral map at a corresponding moment may be output in real time according to the meteorological environment data and spectral parameter information.
[0037] Furthermore, the data acquisition and analysis processor 1 provided in the embodiment of the present invention may also include a signal sending unit for uploading the synchronized meteorological information and crop spectral parameter information acquired to a remote server or a cloud server to meet the needs of remote real-time viewing, storage and control of data.
[0038] The meteorological environmental parameter and spectral synchronous measurement system provided by the embodiment of the present invention combines multiple meteorological sensors and multi-band spectral sensors, and uses a central data processor to synchronously collect information from the two, thereby solving the problem of asynchronous collection of meteorological information and spectral information in the current market, and providing strong data support for better analysis and prediction of crop nutrient deficiencies and making scientific decisions in advance.
[0039] Based on the contents of the above embodiments, as an optional embodiment, the above meteorological environment detection device mainly includes: one or more of an air temperature and humidity sensor, a solar radiation sensor, an atmospheric pressure sensor, a wind speed and direction sensor, and a soil temperature and humidity sensor.
[0040] Among them, the air temperature and humidity sensor is mainly used to obtain the environmental temperature and humidity information of the environment where the tested crop is located; the solar radiation sensor is mainly used to detect the light intensity information of the tested crop in real time; the atmospheric pressure sensor is mainly used to detect the atmospheric pressure of the environment where the tested crop is located; the wind speed and direction sensor is used to detect the wind direction and speed information of the current environment of the tested crop. Among them, each device independently performs its own detection task according to the data acquisition instruction of the data acquisition and analysis processor 1, and feeds back the acquired detection information to the data acquisition and analysis processor 1 in real time.
[0041] It should be noted that in the embodiment of the present invention, the data collection and analysis processor 1 can send corresponding data collection instructions to part or all of the meteorological environment detection devices according to actual detection needs.
[0042] The meteorological environment parameter and spectrum synchronous measurement system provided by the embodiment of the present invention effectively overcomes the defects of existing measurement devices in that crop environmental data and spectral parameters are carried out separately and it is difficult to synchronously collect crop environmental parameter and spectral parameter information. At the same time, by acquiring various meteorological data, the analysis accuracy of the crop growth status analysis model is improved.
[0043] Based on the content of the above embodiment, as an optional embodiment, the provided meteorological environment parameter and spectrum synchronous measurement system may also include: a canopy temperature sensor; the canopy temperature sensor is mainly used to obtain the crop canopy temperature.
[0044] The canopy temperature sensor can be a digital infrared canopy temperature sensor, which measures the canopy temperature of the crop by combining an infrared temperature measuring head with a temperature measuring circuit board. Optionally, the canopy temperature sensor selected in the embodiment of the present invention has the following standards: the wavelength measurement range of the sensor is 0.8 to 1.1 μm, non-imaging, temperature sensitivity within 30 mk, and complies with the RS 485 bus interface standard.
[0045] Since crop canopy temperature plays a great role in determining whether there is water shortage and maturity, and the existing meteorological monitoring parameters lack monitoring of crop canopy temperature, in the meteorological environment parameter and spectral synchronous measurement system provided in the embodiment of the present invention, a canopy temperature sensor that is sensitive to crop moisture status and maturity is added. While obtaining the meteorological data of the measured crop, the canopy temperature of the measured crop is also obtained. The three types of sensors, namely, the meteorological environment detection device, the multi-band spectral sensor and the canopy temperature sensor, are combined, which solves the problem of asynchronous collection of meteorological information, spectral information and canopy temperature information in the current market, and provides strong data support for better analysis and prediction of crop nutrient deficiencies and making scientific decisions in advance.
[0046] Based on the content of the above embodiment, as an optional embodiment, the above multi-band spectral sensor is specifically a CMOS detector; the meteorological environment detection device 1 and the multi-band spectral sensor 2 are respectively connected to the data acquisition and analysis processor 3 through the RS485 bus to achieve communication.
[0047] At present, there are many companies and products producing meteorological stations at home and abroad, and the technology is relatively mature, but there are relatively few companies producing spectrometers. Spectrometers are divided into imaging and non-imaging types. Imaging spectrometers have a large amount of data, which makes storage and analysis difficult, especially for use in unattended outdoor environments. The energy consumption is large, and it is not suitable for long-term observation, and it is even less suitable for use with batteries and solar panels. In comparison, non-imaging spectrometers have a small amount of data, less difficulty in storage and analysis, and relatively low power consumption. Therefore, they are very suitable for monitoring in unattended outdoor environments. Their small amount of data is also very suitable for wireless transmission of data, which plays a vital role in realizing real-time analysis of data. In view of this, the embodiment of the present invention comprehensively considers the advantages and disadvantages of imaging spectrometers and non-imaging spectrometers, and selects non-imaging spectrometers for the detection of spectral parameters.
[0048] Furthermore, non-imaging spectrometers are divided into CCD detectors and CMOS detectors according to the working principle of the core components. Among them, CCD detectors have high power consumption and low data acquisition efficiency, while CMOS detectors have low power consumption and high data acquisition efficiency. Considering the application of long-term in-situ observation in the field, the embodiment of the present invention selects CMOS detectors as the detection device of spectral parameters, which is more scientific and reasonable.
[0049] Optionally, the CMOS detector used in the embodiment of the present invention has a channel response range covering the 400-1000nm band, and by adding filter materials to the CMOS and configuring corresponding lenses, the purpose is to measure the reflectivity information of each band. Its acquisition rate is set to ms level, and it can collect bands with a resolution of 5nm or less in the 400-1000nm band; its output data bit number is 16 bits. Taking into account the particularity of crop physiological ecology, its working band selection is: blue band 400-650nm, 5nm interval; and 651-1000nm, 4nm interval.
[0050] Furthermore, in the embodiment of the present invention, the RS485 bus is used to realize the communication connection between the meteorological environment detection device 1 and the multi-band spectrum sensor 2 and the data acquisition and analysis processor 3, which can fully meet the requirements of signal transmission stability in the field environment.
[0051] The meteorological environmental parameter and spectrum synchronous measurement system provided by the embodiment of the present invention comprehensively considers the characteristics of being used in an unattended outdoor environment, selects a multi-band spectral sensor as a CMOS detector, and uses the RS485 bus as a communication connection method. Under the condition of ensuring a high number of spectral bands and data frequency, it can achieve long-term stable power supply in an unattended outdoor state, reduce the restrictions on the geographical location conditions for the deployment of the sensor, and improve the stability of signal transmission.
[0052] Based on the contents of the above embodiments, as an optional embodiment, the meteorological environment parameter and spectrum synchronous measurement system provided by the embodiment of the present invention may further include a wireless transmission module.
[0053] Among them, the data transmission protocol of the wireless transmission module can be a GPRS remote communication protocol. Further, the collected data can be remotely transmitted and the relevant parameters can be set through the GPRS unit. Since the GPRS remote communication protocol is less affected by the outdoor environment and the signal transmission performance is stable, the meteorological environment parameter and spectrum synchronization measurement system provided by the embodiment of the present invention provides convenience for realizing real-time monitoring data by adding a wireless transmission module for remote data transmission.
[0054] Based on the contents of the above embodiments, as an optional embodiment, the above-mentioned multi-band spectral sensor mainly includes: a spectral incident light detector and a spectral reflected light detector, the spectral incident light detector and the spectral reflected light detector are respectively located on two opposite surfaces of the shell; the interface of the air temperature and humidity sensor, the interface of the atmospheric pressure sensor, the interface of the wind speed and direction sensor, the interface of the soil temperature and humidity sensor and the interface of the canopy temperature sensor are arranged on the shell; the solar radiation sensor is arranged on the surface where the spectral incident light detector is located.
[0055] As an optional embodiment, Figure 2 , Figure 3 and Figure 4 The front, back and side views of the meteorological environment parameter and spectrum synchronous measurement system provided by the embodiments of the present invention are respectively shown in FIG. Figure 2 , Figure 3 and Figure 4 As shown, the meteorological environment parameter and spectrum synchronous measurement also includes a cubic shell, which is used to integrate various parameter measurement devices or interfaces of the devices.
[0056] Specifically, the meteorological environment parameter and spectrum synchronous measurement system provided by the embodiment of the present invention mainly includes a meteorological environment detection device 1, a multi-band spectrum sensor 2 and a data acquisition and analysis processor 3. Among them, the meteorological environment detection device 1 mainly includes an air temperature and humidity sensor, a solar radiation sensor 12, an atmospheric pressure sensor, a wind speed and direction sensor, and a soil temperature and humidity sensor; the multi-band spectrum sensor mainly includes a spectrum incident light detector 21 and a spectrum reflected light detector 22. The system can also include a canopy temperature sensor. Among them, the air temperature and humidity sensor, the atmospheric pressure sensor, the wind speed and direction sensor, the soil temperature and humidity sensor, and the canopy temperature sensor are respectively connected to the data acquisition and analysis processor 3 through corresponding RS 485 interfaces.
[0057] In the embodiment of the present invention, two completely identical non-imaging hyperspectral detectors are used, namely, a spectral incident light detector 21 and a spectral reflected light detector 22, which are respectively arranged on two opposite sides of the shell (for the convenience of description, the spectral incident light detector 21 is called the front side of the shell, and the spectral reflected light detector 22 is called the back side of the shell), so as to determine the absorption spectrum of the crop to be tested to light through the spectral difference detected by the two spectral detectors.
[0058] Furthermore, if Figure 2 As shown, the interface 111 of the temperature and humidity sensor, the interface 131 of the atmospheric pressure sensor, the interface 141 of the wind speed and direction sensor, the solar radiation sensor 12 and the incident light detector 21 can be integrated on the front of the shell.
[0059] Furthermore, if Figure 3As shown, the spectral reflectance light detector 22, the wireless transmission module 5, and the interface 411 of the canopy temperature sensor can be integrated on the front side of the housing.
[0060] Furthermore, as shown in FIG5 , an interface 151 for the soil temperature and humidity sensor may be provided on the side of the housing.
[0061] The meteorological environment parameter and spectrum synchronous measurement system provided by the embodiment of the present invention effectively realizes the combination of three types of sensors by integrating various parameter detection devices or their interfaces on the same housing, and respectively connecting them to the data acquisition and analysis processor through RS485 bus communication, thereby solving the problem of asynchronous collection of meteorological data, spectral information, and canopy temperature information in the current market, and providing strong data support for better analysis and prediction of crop nutrient deficiencies and making scientific decisions in advance.
[0062] Based on the content of the above embodiment, as an optional embodiment, the above solar radiation sensor 12 is a hemispherical lighting structure.
[0063] Specifically, the solar radiation sensor 12 in this embodiment adopts a hemispherical (ground projection radius 1.2 cm) lighting structure, which can receive light within a 180-degree three-dimensional range. Compared with other shapes, while increasing the light contact area, it is more conducive to controlling the distance between it and other measuring devices (or interfaces) within the wired range.
[0064] Optionally, the distance between the solar radiation sensor 12 and other sensors is maintained at 2 cm or more.
[0065] Based on the content of the above embodiment, as an optional embodiment, the meteorological environment parameter and spectrum synchronous measurement system may further include a power module.
[0066] As an option, the power module mainly includes a built-in storage battery 61 and / or a solar panel power supply interface 62. The solar panel power supply interface 62 is connected to an external solar panel.
[0067] Among them, the built-in battery capacity (50,000 mA·h) can ensure normal power supply when the solar panel is not charged for 30 days.
[0068] Furthermore, the remaining voltage information of the battery power can be remotely sent to the viewing terminal through the built-in power detection module.
[0069] Furthermore, the power module further includes a power active switching control unit, which is used to automatically select to be powered by the built-in battery 61 or by the external solar panel through the solar panel power supply interface 62 according to whether the input voltage on the solar power supply interface reaches a preset threshold. Optionally, the threshold can be set to any value between 5-12V.

[0071] Based on the contents of the above embodiments, as an optional embodiment, the meteorological environment parameter and spectrum synchronous measurement system may further include a status indicator light 7, which may be disposed on any side of the shell to indicate information such as the current power supply status of the synchronous measurement system, the working status of each sensor, the data transmission and reception status, and the battery power status according to the colors and brightness of different lights.
[0072] Optionally, a mechanical installation hole 8 may be provided on any side surface of the housing to facilitate installation and fixation of the meteorological environment parameter and spectrum synchronous measurement system.
[0073] The embodiment of the present invention provides a method for synchronously measuring meteorological environment parameters and spectrum, such as Figure 5 As shown, the method mainly collects meteorological information such as rainfall data, solar radiation data, wind speed and direction data, air pressure data, air and soil temperature and humidity obtained by the meteorological environment detection device 1 through the data acquisition and analysis processor 3, and simultaneously obtains the crop incident and reflected spectrum information obtained by the multi-band spectral sensor 2. At the same time, the thermal infrared data reflecting the crop canopy temperature obtained by the canopy temperature sensor can also be synchronously collected. Further, the data acquisition and analysis processor 3 can perform preliminary processing on all the above-mentioned meteorological information to generate corresponding meteorological maps, pre-process the above-mentioned crop incident and reflected spectrum information to generate corresponding spectrum maps, and combine the temperature of the canopy temperature sensor to synchronize and package them to generate the current status information package, and then upload them through the wireless transmission module.

[0076] Step S2, the meteorological environment detection device 1 and the multi-band spectrum sensor 2 respectively feed back the collected meteorological environment data and spectrum parameter information of the tested crop to the data acquisition and analysis processor 3 according to the data acquisition instruction;
[0077] In step S3 , the data acquisition and analysis processor 3 synchronizes the meteorological environment data and the spectral parameter information and uploads them to the central server via the wireless transmission module 5 .
[0078] The device provided in the embodiment of the present invention is used to execute the above-mentioned method embodiments. Please refer to the above-mentioned embodiments for the specific process and detailed content, which will not be repeated here.
[0079] It should be noted that the packaging and processing of data obtained by multiple sensors must follow certain rules so that the terminal data receiving and viewing system can view both the data collected by each sensor and the system working status data through the received data packets. At the same time, each sensor is also required to have a certain ability to resist signal interference to prevent the received data from being erroneously received due to errors. In view of this, the method for synchronous measurement of meteorological environmental parameters and spectra provided in an embodiment of the present invention designs a communication data packet protocol.
