Embodiment Construction

[0060] The method can include several monitoring areas. Each monitoring area contains an independent short-distance wireless communication network based on IEEE802.15.4, which consists of a long-distance node (Long-distance Node) and several short-distance nodes (Short-distance Node). The short-distance nodes mainly collect sensory data, organize themselves into an 802.15.4 network, and send the collected data to long-distance nodes. Long-distance nodes have two wireless communication protocols: IEEE802.15.4 and GPRS / GSM. Its MCU is connected with the GPRS module through the serial port and is responsible for establishing GPRS / GSM communication with the monitoring center and IEEE802.15.4 communication with short-distance nodes. At the same time, long-distance nodes can also collect sensing data. After the data of all node sensors is aggregated to the long-distance node, it is sent to the server of the monitoring center through the GPRS / GSM network. The monitoring center has...

Abstract

The invention discloses a method for acquiring wireless sensor network data of farmland ecological environment information, and relates to the technical field of a method for acquiring wireless sensor network data. The method comprises a plurality of monitoring regions, and each monitoring region comprises an independent short-distance wireless communication network based on IEEE802.15.4; the short-distance wireless communication network is composed of a long-distance node and a plurality of short-distance nodes; each short-distance node mainly acquires the sensor data, and self-organizes a 802.15.4 network, and transmits the acquired data to the long-distance node; and the long-distance node has two wireless communication protocols, namely IEEE 802.15.4 and a general packet radio service (GPRS) / global system for mobile communications (GSM). By the method provided by the invention, large-scale large-area farmland ecological environment information data acquisition is realized, the data can be inquired in real time, the nodes can be controlled, and the cost is low.

Description

[0001] technical field [0002] The present invention relates to the technical field of wireless sensor network data acquisition methods, in particular to a wireless sensor network data acquisition method for large-scale farmland ecological environment information. Background technique [0003] 1. Traditional measurement methods of farmland ecological environment parameters [0004] The traditional measurement methods of farmland ecological environment parameter information are mainly ground measurements. Ground measurement experiments are an important part of the study of these parameters. Insufficient sampling will result in too few sample points and are not representative, and excessive sampling will cause waste of manpower and material resources. At present, the main methods of ground measurement are: direct measurement method and indirect measurement method. [0005] (1) Direct measurement [0006] Including calculation paper method, paper weight method, dry weig...
