The unattended low-power crop growth monitor according to claim 5, characterized in that: The mounting frame is provided with a code, and the specific processing process of the registration and login module is as follows: S1: The user needs to register an account when logging into the monitoring management system for the first time; S2: When registering an account, the user needs to set his / her own login account and password; S3: When registering an account, the user needs to fill in the code on the mounting bracket; S4: After the user registration is completed, he can log in to the monitoring management system using the login account and password set in S2.

7. The unattended low-power crop growth monitor according to claim 6, characterized in that: The specific processing process of the data processing module is as follows: By processing the image information collected by the data acquisition module in real time; Acquire real-time spectral data; Obtaining crop growth monitoring indicators, including crop leaf nitrogen content, leaf nitrogen accumulation, leaf area index, leaf dry weight, chlorophyll a, and fertility; Get the corresponding scale values ​​of crops and scales.

8. The unattended low-power crop growth monitor according to claim 8, characterized in that: The monitoring management system further includes a data retrieval module, which is in communication with the database module. The specific determination process of the data analysis module is as follows: The data processing module processes the image information collected by the data acquisition module to obtain the scale values ​​corresponding to the crops and the scale, and retrieves the threshold values ​​of the growth index information of the crops corresponding to the stage preset in the database through the data retrieval module; The real-time information of various crop indicators processed by the data processing module is compared and analyzed with the threshold values ​​of the growth indicator information of the corresponding stage of crops preset in the database.

9. The unattended low-power crop growth monitor according to claim 8, characterized in that: The specific determination process of the data feedback module is as follows: The data judging module judges the data analyzed by the data analyzing module and the corresponding growth information of crops at each stage in the database module; If the data analyzed by the data analysis module is within the corresponding crop stage growth information threshold range in the database module, the data analyzed by the data analysis module is fed back to the database module through the data feedback module; otherwise, the data analyzed by the data analysis module is fed back to the database module and the mobile terminal through the data feedback module.

10. The unattended low-power crop growth monitor according to claim 9, characterized in that: The monitoring management system further comprises a light monitoring module and a timing module; both the light monitoring module and the timing module are in communication connection with the data acquisition module; The database module is preset with an ambient light threshold, the timing module is preset with timing information, and the data acquisition module is also used to collect monitoring information of the light monitoring module and timing information of the timing module; The data processing module is also used to process the monitoring information of the light monitoring module and the timing information of the timing module collected by the data collection module; The data determination module is also used to determine the monitoring information of the light monitoring module and the ambient light threshold. When the monitoring information of the light monitoring module is not within the ambient light threshold, the timing information of the timing module is determined. If the timing of the timing module ends, the controller controls the fill light bar to turn on, and then controls the four cameras to work to capture the crop growth information. The mobile terminal is also used for the user to input the crop maintenance process and maintenance results.
