Embodiment Construction

[0029] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] figure 1 Shows a logical block diagram of a vehicle communication system according to an embodiment of the present invention, such as figure 1 As shown, the vehicle-mounted communication system includes a vehicle-mounted terminal 100 and an external terminal 200 that are communicatively connected to each other. Here, the external terminal 200 is defined relative to the vehicle-mounted terminal 100. The external terminal 200 is a mobile terminal or a fixed terminal that is not directly mounted on the vehicle. The external terminal 200 includes, but is not limited to, a personal computer (PC:...

Abstract

The invention discloses a vehicle-mounted communication system and method. The system comprises a vehicle-mounted terminal and an external terminal; the vehicle-mounted terminal includes a physical serial port for data transmission to the external terminal; and the external terminal includes a virtual serial port generation device for generating a plurality of virtual serial ports, a data processing device for issuing data to the plurality of virtual serial ports according to a preset data transmission mode, and a plurality of application programs for receiving data from the plurality of virtual serial ports correspondingly. Specifically, according to an application type of the application program corresponding to the data, a data transmission mode is preset; if the application program is a shared one, the data transmission mode is a transparent mode and the data are directly packed and issued to all the virtual serial ports, so that the application program can share the data and thus the data transmission efficiency is ensured. If different data are invoked among all the application programs, the data are packed or decoded according to a virtual serial port communication program before being issued to the virtual serial ports, thereby ensuring data transmission accuracy.

Description

technical field [0001] The invention relates to the field of vehicle communication, in particular to a method and system for vehicle communication. Background technique [0002] In the existing vehicle-mounted communication system, the vehicle-mounted terminal needs to perform data interaction with external terminals. Usually, there is a problem of insufficient physical serial port "resources" during the data interaction process. In order to solve the problem of "insufficient resources" of the serial port, the physical serial port in the vehicle terminal is processed by one-to-many or many-to-many technology, that is, multiple virtual serial ports are set for the application program in the external terminal, and the data from the vehicle terminal passes through the physical serial port After that, it is distributed to the above-mentioned multiple virtual serial ports, and then the data is transmitted to each application program through the virtual serial ports.
