IOV (Internet of Vehicles) communication protocol design method

Abstract

The invention discloses an IOV (Internet of Vehicles) communication protocol design method. An information communication protocol between a vehicle terminal and a cloud terminal comprises data length, vehicle-mounted product ID, data and CRC (Cyclic Redundancy Check), wherein the data is classified into six types; a vehicle information cycle packet, a diagnosis event packet and a buffer retention packet belong to a transmission type; a vehicle information cycle acknowledgement packet, a diagnosis event request packet and a buffer retention acknowledgement packet belong to a receiving type; a data frame structure consists of solid data and dynamic data; the solid data comprises ID definitions of the six types of functional packets, time, vehicle sleep states, delayed information states, delayed meters and vehicle information update mark bits; packets which are not transmitted successfully serve as buffer detention packets. The vehicle information update mark bits are used for determining whether comparison data of the current time and previous time in vehicle information is updated or not and marking the updated data; dynamic data is vehicle information with update changes. By virtue of adopting a method of designing a solid data format and a dynamic data format and setting data mark bits, complete data can be obtained with minimal data expenses, and the IOV data transmission cost is greatly lowered.

AI Technical Summary

Benefits of technology

This technology allows sending or receiving different types of digital files from one device onto another without losing any important bits during communication between them. It also includes an algorithm that keeps track of how many times certain new ones have been lost due to movement within its own system. Additionally, this technology helps reduce costs associated with transmitting large amounts of data over wireless networks while still maintaining accurate reception at all locations around us.

Problems solved by technology

This patented technical problem addressed by this patent relates to reducing excessive usage of radio access technologies like cellular phone calls during driving without compromising their effectiveness over longer periods of time. Additionally, some existing methods require expensive equipment and can only work with specific types of devices.
