Data interaction method, storage medium, electronic equipment and vehicle

Abstract

The invention discloses a data interaction method, a storage medium, electronic equipment and a vehicle. The data interaction method comprises the steps: obtaining a current protocol configuration file of interaction data, wherein the protocol configuration file is used for defining the attribute of each transmission field in the interaction data and the length of the data type to which the interaction data belongs; when a protocol modification request is detected, modifying the current protocol configuration file according to modification content in the protocol modification request to obtain a new protocol configuration file; and performing data interaction according to the new protocol configuration file. According to the data interaction method, when the protocol is modified, only the protocol configuration file needs to be modified, the protocol does not need to be modified, and therefore the protocol modification efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a data interaction method, a storage medium, electronic equipment and a vehicle. Background technique [0002] As cars become more and more intelligent, there is an increasing need to define a set of protocols for the interaction between the vehicle and the supporting systems that provide intelligent services in the background. In related technologies, due to different requirements during the process of defining the protocol, different types of fields representing certain meanings are defined during the process of defining the protocol. [0003] However, the above-mentioned related technologies have the following problems: 1) The defined protocol contains variable-length fields, such as fields representing the number of drive motors, vehicle alarm data, etc., which will cause the defined protocol to be unable to be processed in parallel, As a result, the processing efficiency i...

Problems solved by technology

[0003] However, the above-mentioned related technologies have the following problems: 1) The defined protocol contains variable-length fields, such as fields representing the number of drive motors, vehicle alarm data, etc., which will cause the defined protocol to be unable to be processed in parallel, As a result, the processing efficiency is reduced; 2) If some protocol fields are added or reduced in the process of modifying the protocol, the vehicle-mounted protocol interpretation terminal and background applications need to be re-modified and jointly debugged, which increases the time for research and development costs and also leads to the need for A lot of time is spent on regression testing the interpretation of the protocol fields; 3) the protocol cannot identify the length of each data field, so the data stream needs to be intercepted artificially to calculate the value represented by the field, which increases the code of the protocol interpreter Complexity, and it is not convenient for future code maintenance; 4) If part of the content in the middle of the protocol is modified, then the protocol definition behind the modified part needs to be re-parsed
