Problems solved by technology

[0007] The existing protocol is converted to middleware developers through manual coding on the basis of understanding the vehicle CAN protocol, that is, the car company needs to disclose the body network protocol, which is not conducive to protecting the intellectual property rights of the car company, and the efficiency of manual coding is not high. Bad sex and other shortcomings
The existing development methods are not suitable for the development and application of middleware

Embodiment Construction

[0033] The technical solutions of the present invention will be further described below in conjunction with specific embodiments.

[0034] The structure of the protocol conversion implementation flowchart is as follows: figure 1 As shown, car companies input the agreement through the analysis of the DBC file to form a database of variables. The use of the database is to facilitate the conditional search and secondary import of agreement information. The data item contains the information describing the input, including CAN ID, start bit, end bit, offset, scale factor and a series of information that accurately describe the protocol variables. The message bus protocol file is a file describing the message bus communication protocol of the IoV middleware.

[0035] The processing method module analyzes the information obtained from the configuration, including variable matching, shifting, and search operations, obtains the input parameters of the code template, and passes it to ...

Abstract

The invention discloses a method for generating configuration for middleware protocol conversion of the Internet of vehicles. According to the method, the rapid development of a protocol conversion module is realized through configuration, vehicle enterprise communication protocol conversion parameters are added into a configuration tool through reading DBC (DataBase Commander) file description information which is compiled according to the communication protocol of the Internet of vehicles, configuration information is stored in a database, and middleware protocol conversion module codes of the Internet of vehicles are automatically generated by using protocol conversion template files; a vehicle body network is rapidly integrated with other networks, so as to realize the communication of the Internet of vehicles; the configuration tool can automatically generate configuration files and an application framework and carries out error check on the configuration of a user, worker involvement is avoided as much as possible, and the error rate is lowered, so that the stability of the protocol conversion module can be actively improved.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Vehicles, and relates to a method for generating configurations of middleware protocol conversion of the Internet of Vehicles. Background technique [0002] The Internet of Vehicles is one of the key development targets of the Internet of Things in the future. We can realize some functions of handheld smart devices such as entertainment and phone calls through vehicle-mounted terminal equipment. At the same time, we can also remotely understand the working status of various components of the vehicle, the location of the vehicle, and the remote update of in-vehicle equipment programs in real time through the wireless network. Real-time statistics and analysis of vehicle location can also be realized through vehicle-to-vehicle communication and vehicle-to-road communication, providing real-time data for traffic dispatching and vehicle active safety systems. Therefore, the vehicle terminal a...
