Embodiment 1

[0041] Such as Figure 1-Figure 2 As shown, an agricultural data acquisition system based on a distributed edge network structure includes several wireless sensors, several edge devices and a central server. The wireless sensors and edge devices communicate with each other through a wireless network, and the edge devices communicate with each other through a wireless network. Central server communication.

[0042] In this embodiment, the sensors of the same type are divided into one group, and the sensors of this group upload data through one or multiple edge devices of the same type.

[0043] Preferably, the wireless sensor is a sensor provided with an NB-IOT communication module.

[0044] Preferably, the wireless sensor is used to collect farmland data, and the farmland data is soil pH data, soil temperature and humidity data, surface temperature and humidity data and illuminance data.

[0045] Preferably, the edge device is a data collector, and the data collector include...

Embodiment 2

[0048] Such as figure 2 The agricultural data acquisition method based on the distributed edge network structure described in the shown embodiment 2 is realized on the basis of the agricultural data acquisition system based on the distributed edge network structure described in the first embodiment, including the following step:

[0049] Step 1: Establish an agricultural data acquisition system based on a distributed edge network structure, set the wireless sensor as the anchor node, set the edge device as the intermediate node, and set the central server as the central node;

[0050] Step 2: Initialize the wireless sensor network, including the following steps:

[0051] Step A1: All anchor nodes have their own unique ID numbers and sensor types solidified before leaving the factory;

[0052] All intermediate nodes send initialization information to the central node, and the initialization information includes the jump number of the intermediate node and the appearance ID n...

Abstract

The invention discloses an agricultural data acquisition system based on a distributed edge network structure and a method thereof, which belong to the technical field of communication, and comprise a plurality of wireless sensors, a plurality of edge devices and a central server. The wireless sensors is connected with the edge devices by a wireless network. the edge devices communicate with the central server through the wireless network, the technical problem that the types of the anchor nodes are classified when a network framework is initialized is solved, the same type of intermediate nodes can be automatically selected for edge calculation according to the types of the anchor nodes, classification work is completely carried out at the intermediate nodes. The burden of the center node is reduced, and the processing speed of the center node is increased.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to an agricultural data acquisition system and method based on a distributed edge network structure. Background technique [0002] Edge computing is a new model developed with the large-scale application of wireless sensor networks, that is, to enable each edge device in the network to have data collection, analysis and calculation, communication and intelligent processing capabilities. Therefore, the accuracy of the node positions in the network is even more required. [0003] When edge computing is used for network architecture, the traditional technology only considers the number of hops of its nodes, and does not consider the type of the anchor node. After the data of the anchor node is uploaded to the central node through the intermediate node, the central node needs to check the type of the anchor node. Classification will increase the burden on the central node. Yes, whe...
