Embodiment Construction
[0036] A non-limiting embodiment is given below in conjunction with the accompanying drawings to further illustrate the present invention.
[0037] 1. Description of the entire middleware data communication data flow
[0038] as attached figure 1 As shown, according to the composition of the Internet of Vehicles middleware and the data interaction relationship between the application service program and the middleware, message communication can be divided into two aspects: message sending and message receiving. In the application of the Internet of Vehicles, the messages are divided into two types of messages: local messages and remote messages. Local messages refer to messages transmitted in the body network, while remote messages refer to messages that the vehicle interacts with external devices or interrupts. Different message headers can be used to distinguish message types during message definition. The data flow in these two aspects will be described respectively belo...

Abstract
The invention discloses a framework system and implementation method of a middleware applied to a car networking, and relates to the technical field of an embedded middleware applied to the car networking. The framework system includes a middleware message bus module, a car networking application component module, a car networking middleware message broker module, a car networking security component, and a car networking communication protocol adaptation layer. The car networking middleware application component forms a standard function component; the car networking middleware message broker is used for analysis and classification of all kinds of messages in the car networking; a remote connection request is verified by a security component; if the remote connection request passed verification, a corresponding application component thread is searched in a car networking message bus; and through the message bus, a message channel is established between a remote terminal and a local application component or middleware message broker, and then communication is carried out. The car networking communication protocol adaptation layer is used to shield differences between a platform and an enterprise protocol, and to provide a unified communication call interface. According to the invention, the reusability of the code and the development efficiency of the application program are improved.
Description
technical field [0001] The invention relates to the technical field of embedded middleware for Internet of Vehicles applications, in particular to a middleware architecture for Internet of Vehicles applications. Background technique [0002] In the national "Twelfth Five-Year" plan for the development of the automobile industry, it is clearly proposed to vigorously promote the Internet of Things strategy based on vehicle informatization by means of 3G wireless Internet of Things and intelligent remote control; the plan also proposes to develop broadband convergence security The next generation of national infrastructure to promote the application of the Internet of Things. Among the branches of the Internet of Things, the easiest to form system standards and the application with the greatest industrial potential is the Internet of Vehicles. As the application of the Internet of Things in the transportation field, the Internet of Vehicles will become an important part of the...
