Abstract

The invention discloses a wireless sensor network gateway for farmland information acquisition. The wireless sensor network gateway comprises a control module used for controlling the data acquisition, storage, display, enquiry and remote transmission of each sensor node in a wireless sensor network, a communication module connected with the control module, used for realizing communication between the gateway and the wireless sensor network and providing the wireless Internet function for the gateway, and a storage module connected with the control module and used for storing the data acquired by each sensor node in the wireless sensor network into a SQLite database. The gateway of the invention can realize rapid, reliable and low-cost remote acquisition of thhe agricultural production environment information.

Description

technical field [0001] The invention relates to the technical field of precision agriculture, in particular to a wireless sensor network gateway for collecting farmland information. Background technique [0002] There are problems such as land resource degradation and serious land pollution in the use of land resources in our country; on the other hand, the uneven distribution of water resources in time and space in our country and the low utilization rate of water resources seriously threaten agricultural production. Therefore, it has great potential to develop precision agriculture, change the existing farming mode, and increase the output per unit area. The core of the "precision agriculture" technical thinking is to analyze the environmental factors that affect crop growth (such as soil structure, topography, plant nutrition, water content, pests and weeds, etc.), to take economic and effective control measures, and to implement positioning control as needed. "Precision...
