Embodiment Construction

[0041] The invention is an active induction-based agricultural Internet of Things communication method, which can automatically select the best path for agricultural Internet of Things communication according to preset rules.

[0042] According to the characteristics of large-scale farmland monitoring, the location of the agricultural Internet of Things information collection nodes is basically fixed, and the node location can be preset when arranging the nodes. The position distribution of the nodes is evenly arranged according to the environment, soil quality, and soil nutrient content. Under these characteristics, the agricultural Internet of Things communication method includes the following steps:

[0043] 1. Node location planning

[0044] There are two ways of node location planning

[0045] (1) In the case of a GIS map, the nodes are arranged in the farmland, and the satellite positioning data at the nodes are measured by a GPS position measuring instrument;

[0046...

Abstract

The invention discloses an active-induction-based agricultural internet things communication method. The communication method comprises the following steps of: generating a node communication path map according to a node geographic position; finding out a former node and a next node, each of which has the shortest distance away from the current node in the node communication path by determining the distance between the current node and the adjacent former node, as well as the distance between the current node and the adjacent next node through a coordinate calibration method; traversing all the nodes and establishing a shortest-path communication map; and establishing a shortest path link with a target node according to the shortest-path communication map when any node transmits information, and sending signals to the target node. Due to the active-induction-based communication path, the communication distance is the shortest, the communication power consumption is the less and the transmission speed is increased. An upper computer can timely know the crop growing situations in each area through the shortest-path communication map, thus facilitating management and operation and reducing the maintenance cost..

Description

technical field [0001] The invention relates to a communication method of the agricultural Internet of Things, in particular to an active induction-based communication method of the agricultural Internet of Things. Background technique [0002] my country has a large population and limited agricultural land. Since the reform and opening up more than 30 years ago, China's traditional agriculture has gone through a high-input, high-yield road of increasing grain production by exchanging resources for production. However, with the excessive use of pesticides and fertilizers in agricultural production, it will not only lead to waste of resources, but also may lead to the deterioration of the ecological environment of farmland. The development of my country's agriculture will face problems such as resource shortage, ecological deterioration, weak foundation, and insufficient scientific and technological content. In order to ensure the supply of agricultural products in our coun...
