Wireless acquisition terminal for crop-atmosphere-soil information and acquisition method

Abstract

The invention discloses a wireless acquisition terminal for crop-atmosphere-soil information. The wireless acquisition terminal comprises a sensor module, a microprocessor module, a wireless communication module, a real-time clock module, a power control module and a power module, wherein the power module is used for supplying power to the real-time clock module and the power control module respectively; the power control module is connected with the sensor module, the microprocessor module and the wireless communication module respectively; and the microprocessor module is connected with the real-time clock module and the power control module in sequence. When the microprocessor module receives a signal acquired by the sensor module successfully, the power control module is controlled to be on and off by controlling a pulse signal of the real-time clock module to turn over so as to achieve long-time sleep and awakening of the wireless acquisition terminal and save the working energy consumption of the terminal. The invention further discloses an acquisition method, which achieves synergistic real-time acquisition of farm crop, environment and soil information in wide-range environments and is suitable for wide-range farm field working environments.

Description

technical field [0001] The invention relates to a crop-atmosphere-soil information wireless collection terminal, in particular to a farmland information wireless collection device, which is suitable for real-time monitoring of farmland information under long-term, large-scale, and unattended conditions, and belongs to the field of the agricultural Internet of Things. Background technique [0002] In the process of traditional crop production management, there is often a lack of accurate quantitative understanding of crop growth status; or although quantitative analysis of crop growth indicators is required, destructive sampling and chemical analysis are required, which has poor timeliness and often leads to excessive fertilization in production (especially Nitrogen fertilizer) or insufficient fertilizer application (such as some trace elements), will easily lead to increased production costs, environmental pollution and reduced land sustainable production capacity. Taking ni...

Problems solved by technology

[0003] However, in the existing technology, the establishment of crop production intelligent management system is restricted by sensor technology, agricultural engineering, crop growth monitoring and crop cultivation management decision-making technology. It is immature, and there are still defects and deficiencies such as single monitoring indicators, small range of monitoring points, cumbersome monitoring methods, high cost, difficult construction, and susceptibility to interference, which cannot well meet the actual application needs.
