A data processing system based on NB-IoT

Abstract

The invention belongs to the technical field of Internet of Things data processing, especially a data processing system based on narrowband Internet of Things. Aiming at the problems of low data transmission rate and poor security in the prior art, the following solution is proposed: including a central processing unit, data The analysis module, the cache module and the IOT connection management platform, the output of the central processing unit are respectively connected to the data analysis module and the input of the cache module, and the output of the data analysis module is connected to the input of the data management module. After real-name authentication, log in to the IOT connection management platform to download data, and a data comparison and detection module is connected between the invalid data unit screened out by the data management module and the cache module. The invention effectively improves the data transmission and conversion rate, prevents users from receiving invalid data, has high data interaction security, and is convenient for maintenance.

Description

technical field [0001] The invention relates to the technical field of Internet of Things data processing, in particular to a data processing system based on narrowband Internet of Things. Background technique [0002] The Internet of Things refers to a network in which people and things, and things and things are interconnected by deploying various devices with certain perception, calculation, execution and communication capabilities, obtaining information in the physical world, and realizing information transmission, collaboration and processing through the network. In short, the Internet of Things is to realize the interconnection between people and things, and things and things. Its applications include smart grids, smart agriculture, smart transportation, and environmental detection. NB-IOT (Narrow Band Internet of Things, based on Cellular narrowband Internet of Things) technology, as a communication technology for the Internet of Things, is an emerging WAN network tra...

Problems solved by technology

[0003] However, the internal design of NB-IOT's low power consumption and low cost is mainly realized based on technologies such as PSM (PowerSaving Mode, power saving mode) and eDRX (Enhanced Discontinuous Reception, enhanced discontinuous reception), with deep sleep , the property of long sleep makes the signaling not reachable at any time and the communication delay is long. Devices using NB-IOT technology for communication, including transmitting devices and receiving devices with built-in NB-IOT chips, when the transmitting device moves past the need When the receiving device (monitoring point / data collection point) is communicating, the NB-IOT chip of the transmitting device will be in a long sleep, and normal communication cannot be completed. The security of data transmission is poor, and invalid data cannot Timely screening and processing
