Embodiment Construction

[0022] In an embodiment of the present invention, an optimal sparse sampling method for environmental signals suitable for agriculture, specifically includes the following steps:

[0023] S1: First erect multiple support columns in the field, where the distance between two adjacent support columns is 30m, and fix different types of sensors a1, a2, a3, and a4 on the multiple support columns in turn from top to bottom At the same time, different indicator lights and voice announcers should be installed on the same side of the sensors a1, a2, a3 and a4 to give separate alarms;

[0024] S2: Obtain multiple sets of initial signals 1 and synchronous signals from sensors a1, a2, a3, and a4 through the converter, and use the acquired multiple sets of synchronous signals to process multiple sets of initial signals 1 to obtain multiple sets of initial signals 2;

[0025] S3: Use the microcontroller to collect and process multiple sets of initial signals 2, and obtain the current value ...

Abstract

The invention relates to the technical field of agricultural environment signal acquisition, and discloses an environment signal optimal sparse sampling method suitable for agriculture, which specifically comprises the following steps: S1, erecting a plurality of support columns in a field, the distance between every two adjacent support columns being 30m; and sequentially fixing different types of sensors a1, a2, a3 and a4 on the plurality of supporting columns from top to bottom. According to the invention, a plurality of groups of supporting columns with sensors are erected in the field, sothat the problem of inaccurate acquisition indexes caused by terrain and climate influence can be solved, the current agricultural environment signal can be averagely sampled by adopting an optimal sparse sampling mode, the accuracy of a sampling result is improved. Moreover, different types of sensor indexes can be alarmed in time through the color indicating lamps and the voice broadcaster, sothat a worker can check whether the current agricultural environment quality exceeds the standard or not in time, and subsequent corresponding regulation and control are facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural environmental signal acquisition, in particular to an optimal sparse sampling method for environmental signals suitable for agriculture. Background technique [0002] The agricultural environment refers to the totality of various natural and artificially modified natural factors that affect the survival and development of agricultural organisms, including agricultural land, water, atmosphere, organisms, etc., and is an important part of the natural environment on which human beings depend. , belongs to the category of China’s legal environment. The agricultural environment is composed of climate, soil, water, topography, biological elements and human factors. Each environmental element has quality problems at different times and spaces. The current outstanding problem of China’s agricultural environmental quality is environmental pollution and ecological destruction. [0003] However, althou...
