Virtual instrument-based farmland sprinkling irrigation monitoring system

Abstract

The invention discloses a virtual instrument based farmland sprinkling irrigation monitoring system which comprises a data control processing platform, a sprinkling irrigation automatic execution mechanism and a data acquisition module, wherein the data control processing platform acquires GPS information through a serial port, and acquires the environment temperature information, the crop temperature information and the soil water content information through the data acquisition module; the data processing platform is in both-way connection with a data analysis module and is in one-way connection with the sprinkling irrigation automatic execution mechanism capable of performing automatic sprinkling irrigation on corps; the data acquisition module is in both-way connection with a databasemodule; the database module is in both-way connection with a GIS geographic information module; the data processing platform comprises a digital signal processing module, a data control decision module and a data management module. The system disclosed by the invention can automatically start or stop sprinkling irrigation as required, and has high utilization rate of water quantity.

[0002] Virtual instrument is a computer data acquisition and signal processing system constructed according to the requirements of the instrument. It is based on the hardware platform of the computer and its accessories, with software such as data acquisition, logic (signal processing), measurement and control, analysis and display functions as the core. , plus the necessary A / D, D / A and other digital acquisition, numerical control card, signal conditioning and other electronic components to achieve a digital intelligent signal acquisition measurement and control analysis system, generally has a beautiful image of the software interface instrument panel, with a powerful A variety of instrument functions have been able to complete and exceed most of the functions of traditional instruments; at present, most of the irrigation areas at home and abroad, whether large or small, are mostly controlled by traditional manual methods due to the limitations of design level and construction technology. The existing problems of the system are: clumsy operation (manual operation is mostly used), information transmission and response are extremely slow, and a large number of operators are required, and the annual operating cost is high; the water utilization rate is low, and water resources are seriously wasted; the water volume is difficult to control accurately, It is easy to cause over-irrigation and under-irrigation
