An area-fixed edge computing system and a method for heterogeneous city internet of things

Abstract

The invention relates to an area-fixed edge computing system and a method for heterogeneous city internet of things, belonging to the technical field of the internet of things. The method comprises the following steps: S1, dividing the area into a plurality of virtual internet of things small grids according to the distribution density and position of GIS information and sensors in a specific areaof the city; S2, set at least one calculation point in each small mesh to be edge calculated, capture various sensor data in that small mesh, decoding the sensor data, calculating and screening out effective information, store, encrypting and uploading the information to a computing station; S3, combine a plurality of small grids into an enlarged grid, and arrange a computing station with multiple information sending and receiving and high computational power, picking up that uploading information of the computing points under the jurisdiction, classifying, analyzing and calculating, and deeply fusing heterogeneous information to generate imperceptible new information; S4: Upload the new information to the background server and download it to the application side. The invention converts the calculation of the edge into the calculation of the stationary type of the regional center, and improves the practicability and efficiency of the calculation of the edge of the urban internet of things.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and relates to a fixed-type heterogeneous urban Internet of Things regional edge computing system and method. Background technique [0002] The intelligent management of cities, parks, scenic spots, construction sites, communities, buildings, transportation facilities, rivers, lakes, etc. puts forward high requirements for the information processing of various related infrastructures. It is necessary to make full use of the Internet of Things technology to collect, process, store, analyze, transmit and intelligently solve the massive data generated by the sensing devices of various related infrastructures. In this way, the integrated smart city IoT application of "sense, transmission, knowledge, and use" can be realized, and the problems in a certain facility can be immediately known, the location and degree of the problem can be confirmed immediately, and the problem can be solved...
