Abstract

The invention provides a safe data transmission method of a smart instrument system. The safe data transmission method comprises the steps that a, a handheld device obtains a data encryption key from a data management center; b, the handheld device encrypts the data encryption key and data collected from a smart instrument to generate encrypted data frames, and the encrypted data frames are transmitted to the data management center. The safe data transmission method of the smart instrument system achieves cryptograph transmission of an overall message, and is high in data transmission safety and reliability.

Description

technical field [0001] The invention relates to a data security transmission method, in particular to a data security transmission method applied to an intelligent instrument system. Background technique [0002] At present, smart meter systems are widely used in the fields of copying, billing and monitoring of electric meters, water meters and gas meters in cities and rural areas. In the process of data collection (such as the degree of electricity meters), hand-held devices are usually used to extract data such as meter readings and geographic information through infrared, barcode scanning, GPS positioning, camera and other data collection technologies, as well as image processing and pattern recognition technologies. However, since this type of data is accessed to the data management center through mobile communication networks and the Internet, the data is vulnerable to malicious attacks, theft and tampering during transmission. Contents of the invention [0003] In v...
