Method and device for high-speed data synchronization between Internet of Things equipment and data center

Abstract

The invention provides a method and device for high-speed data synchronization between Internet of Things equipment and a data center. The method comprises that a time delay value is calculated by recording a time label value in a data transmission process; the time delay value is analyzed, a reasonable encryption scheme is designed according to the analysis result to encrypt the data to reduce the delay of data transmission and improve the security of data transmission; hybrid encryption is carried out through an AES encryption method and an optimized ECC encryption method, so that the calculation efficiency of an encryption algorithm is improved, and the stability and integrity of data transmission are ensured; and networking is carried out through ZigBee and NB-IoT, the situation that data cannot be synchronously updated due to weak signals is avoided, the signal stability is enhanced, and the data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the field of data synchronization, in particular to a method and a device for high-speed data synchronization between an Internet of Things device and a data center. Background technique [0002] The definition of the Internet of Things is to connect any item to the Internet through information sensing equipment such as radio frequency identification, infrared sensors, global positioning systems, and laser scanners, in accordance with the agreed agreement, for information exchange and communication, so as to realize the security of items. A network of intelligent identification, positioning, tracking and management. Therefore, the basic characteristics of the Internet of Things can be summarized as overall perception, reliable transmission and intelligent processing, and these basic characteristics closely revolve around the flow of information. [0003] At present, in the Internet of Things technology, the data transmission mo...

Problems solved by technology

As Internet of Things devices become more and more intelligent and personalized, data transmission becomes more and more complex, and various data are mixed together, resulting in a long delay in the control terminal and data synchronization, resulting in slow response of cluster services; in the process of data transmission In the process of data transmission, most of the data transmission process is based on the http protocol or https protocol, but the http protocol and https protocol have a fatal shortcoming, that is, they are not safe enough. The existing technology often uses an encryption method to encrypt all the data that needs to be transmitted. , resulting in slow data transmission speed and complex time delay; IoT devices usually use wireless transmission technology, often due to unstable network environment, the data of IoT devices and data centers are not completely updated synchronously
