Sensor signal processing system based on secure network

Abstract

The invention discloses a sensor signal processing system based on a secure network. The system comprises a sensor module, a sensor interface unit, a data transmission unit, a data processing unit, adata encryption unit, a data sending unit, a security network module, a network protection module, an identity authentication module, a security management module, a network repair module, a network detection module and a network authentication module. After data of the sensor module is processed through the data processing unit, the data sending unit transmits the data through the safety networkmodule, a network used for transmitting the data is protected and subjected to safety detection through the network protection module and the network detection module, and meanwhile the data is encrypted through the data encryption unit. Through the identity authentication module and the network authentication module, the security information of the user and the network is authenticated, so that the security of the data in the network transmission process is ensured, the data loss or leakage is avoided, and the data transmission security of the sensor module is improved.

Description

technical field [0001] The invention relates to the technical field of sensor signal processing, in particular to a sensor signal processing system based on a safety network. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first link to realize automatic detection and automatic control. The existence and development of sensors allow objects to have senses such as touch, taste, and smell, and make objects come alive slowly. Usually according to its basic perception function, it can be divided into ten categories such as thermal ...
