The invention discloses a method and a system for encrypting and receiving health data of train driving equipment, belonging to the technical field of satellite-ground information communication. The method of the invention includes: collecting health data of train driving equipment, using the image data in the health data as a carrier for sending and receiving data, and hiding other data in the health data except the image data in the redundant space of the carrier; The scramble method and key pair scramble and encrypt the image data that hides other data to generate transmission data; send the transmission data, decrypt the transmission data after receiving the transmission data, and obtain the health data of the train drive equipment. The invention improves the safety performance in the process of data satellite-to-ground transmission, and reduces the safety risk during train operation while improving the safety performance in the process of data satellite-to-ground transmission.
Description
technical field [0001] The present invention relates to the technical field of satellite-ground information communication, and more particularly, to a method and system for encrypting and receiving health data of train drive equipment. Background technique [0002] At present, rail high-speed trains and high-speed railways have achieved leapfrog development in my country. The total mileage of high-speed railway lines has reached nearly 30,000 kilometers, surpassing the sum of other countries in the world. The commercial operation speed of high-speed trains exceeds 350km / h, and can even reach more than 400 kilometers per hour. Under such a high operating speed, various complex safety protection technologies are required to ensure the safety of its operation. Among them, the health status detection of train driving equipment and the detection data are safely sent to the high-speed rail operation management center through satellite-to-ground transmission, and the driving equipm...
