Sensor sensed event judgment and alarm system and method based on edge information

Abstract

The invention relates to a sensor sensed event judgment and alarm system and method based on edge information. The system includes a sensed data input module which quantifies the data collected by a sensitive component of a sensor to form formatted sensed data, an edge computing module which extracts the features of the sensed data to form edge computing time domain information, a fusion processing module which maps and fuses the edge computing time domain information in the space domain to form a spatial-temporal information fusion processing result, and an event judgment and alarm module which compares the spatial-temporal information fusion processing result with preset event classification parameters to form an event judgment result and sends event alarm information. There is no need for all data to enter the cloud according to the demand, so that the consumption of communication resources is reduced, the communication transmission delay is reduced, and event judgment and alarm isrealized by compromising the energy consumption and the transmission and processing delay.

Description

technical field [0001] The invention relates to edge computing and cloud computing technologies in the Internet of Things, and in particular to a sensor-perceived event judgment and alarm system and method based on edge information. Background technique [0002] The Internet of Things is the extended application and network extension of the communication network and the Internet. It uses perception technology and intelligent equipment to perceive and identify the physical world, and through network transmission and interconnection, it performs calculation, processing and knowledge mining to realize information interaction between people and things, and between things and things. and seamless link to achieve real-time control of the physical world, precise management and scientific decision-making. [0003] Due to many factors such as limited energy and limited computing power of front-end sensing sensors, the current hierarchical architecture of the Internet of Things mainly...

Problems solved by technology

In this mode, although the computing pressure and energy consumption of sensors are reduced, in large-scale deployment application scenarios, after centralized cloud aggregation, it will inevitably bring huge processing complexity to the cloud.

At the same time, the centralized aggregation processing mode in the cloud also faces the problem of high transmission and processing delays, which has obvious shortcomings for applications that require low-latency and time-effective guarantees.
