The present invention relates to the technical field of road information processing, and specifically discloses a data encapsulation method. The method includes: generating header file data of a target data encapsulation package based on the basic attribute data of road users; data, using the driving data as the integrated data of the target data package; obtaining the predefined data of the road user, and using the predefined data as the reserved data of the target data package; The data, the integrated data and the reserved data are encapsulated to obtain the target data encapsulation package. The present invention encapsulates richer data information, adopts a more complex data structure, considers a more scalable data encapsulation method, adds more secure redundant data and an encryption mechanism, and provides a new type of data encapsulation The method ensures the information security of the encapsulated data at the same time.
Description
technical field [0001] The invention relates to the technical field of road information processing, in particular to a data encapsulation method and device. Background technique [0002] With the development of the economy, the sales volume of automobiles has increased year by year, and the automotive electronics market has also entered a period of rapid development. big pressure. Traffic congestion, frequent traffic accidents, and serious environmental pollution are plaguing cities. How to monitor the status quo of vehicles and traffic through information technology, especially the supervision of national key operating vehicles, has become a hot spot in the research of the transportation industry. [0003] At present, through the establishment of a networked control system for operating vehicles, data sharing and forwarding are realized by encapsulating the data in the vehicle-road coordination system, and unified management is realized through unified protocols, unified ...
