Abstract

The present invention provides a data compression transmission method based on an air-ground integration car networking system, belonging to the field of the data compression technology. The problems are solved that the data volume is large in the car networking system based on air-ground integration and the data compression efficiency is low and the transmission speed is low in the transmission process. The method comprises: extracting data collected at N time moments, and performing pre-compression process of partial extracted data; and processing the average speed data, the N rows of traffic density data, n rows of traffic flow data, I rows of environment temperature data through adoption of a run coding compression algorithm. The run coding compression algorithm comprises: after performing classification processing of the n rows of road vehicle average speed data, n rows of traffic density data, n rows of traffic flow data and I rows of environment temperature data, transmitting the data after run coding compression to a vehicle terminal through the number one wireless transmitter-receiver set of an aerial photo unmanned aerial vehicle system. The data compression transmission method based on the air-ground integration car networking system is suitable for data compression and transmission.

Description

technical field [0001] The invention belongs to the technical field of data compression. Background technique [0002] With the development of Internet of Vehicles technology, in the process of data interaction with vehicles, the amount of data involved is increasing. The realization of the Internet of Vehicles function usually uses data as the basis for judgment, such as road location data, battery operating voltage in the car, charging and discharging current, temperature, etc. Therefore, timely and fast transmission of these data is particularly important. As the amount of data increases, it brings difficulties to data transmission and storage. In order to reduce the sending time and storage space of data information during remote data transmission, it is necessary to effectively compress these data. Contents of the invention [0003] The invention aims to solve the problems of large data volume, low data compression efficiency and slow transmission speed in the trans...
