Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application. The relevant directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship between the components in a certain posture (as shown in the drawings). Sports conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0034] As mentioned in the background art, in the prior art, data analysis services are deployed on the cl...

Abstract

The invention discloses a wireless sensor network system. The system comprises a system sensor node, an aggregation node and an edge node, wherein the system sensor node collects environment data anduploads the environment data to the corresponding aggregation node; the aggregation node receives the environment data sent by the sensor node in a corresponding data collection period, pre-processesthe received environment data and then sends the preprocessed environment data to the edge node; and the edge node receives the environment data sent by the aggregation node and analyzes the environment data to determine whether a corresponding emergency event occurs or not. According to the scheme, the efficiency and reliability of data processing in an emergency scene can be improved, and resources are saved.

Description

technical field [0001] The technical field of data analysis of the present invention particularly relates to a wireless sensor network system. Background technique [0002] In recent years, research on the monitoring of emergency scenarios has attracted more and more attention from academia and industry, and has been studied together with some emerging technologies such as edge computing, machine learning, wireless sensor networks, and cloud computing. [0003] In the prior art, when collecting environmental data of an emergency scene, it is generally based on sensor nodes and aggregation nodes. Among them, the sensor node can collect data and upload it to the sink node, and can also forward the data of other nodes. The aggregation node has a relatively strong processing capability, so it is responsible for the communication between the sensor network and the external network, and realizes data processing and node management functions. Data analysis is generally based on a...
