Abstract

The invention provides an interaction device, an information processing method and system, an information detection method and system, a storage medium, and a terminal. The interaction device comprises a first wireless communication device and a second wireless communication device. The first wireless communication device is used for modulating to-be-sent covert communication data to a dynamic cyclic shift vector after entering a specific mode, so as to enable service communication data to shift dynamically according to the dynamic cyclic shift vector to form modulated communication data, wherein the covert communication data is communication data correlated with the specific mode. The second wireless communication device is used for determining whether service communication data is received at present, demodulating the service communication data if the service communication data is received at present so as to detect the covert communication data modulated on the service communication data, and intercepting mixed communication data if the service communication data is not received at present, demodulating the mixed communication data so as to read the covert communication data. The interaction device is highly compatible with systems, is compatible with early warning information transmission between most mainstream communication signals, and transmits intelligent transportation information without occupying extra channel bandwidth.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, relates to a processing / detection method / system, in particular to an interaction device, an information processing / detection method / system, a storage medium and a terminal. Background technique [0002] In recent years, research on intelligent driving systems has received widespread attention worldwide. Driving safety is the most important part of the intelligent driving system. From the perspective of vehicle engineering technology, with the rapid development of vehicle vision, laser guidance, millimeter wave radar and other technologies, driving safety is gradually improving. Take Tesla, the leading international intelligent driving giant, as an example. At the end of 2016, Tesla announced its latest intelligent driving hardware system, Autopilot 2.0. The system integrates 8 cameras (3 in the front, 3 in the rear, one left and one right; divided into wide-angle, telephoto, etc....
