Embodiment Construction

[0038] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0039] see figure 1 , is a tractor CAN system according to an embodiment of the present invention, comprising a plurality of functional control units inside the tractor, the plurality of functional control units are connected through a CAN bus, and a CAN transceiver is connected to the CAN bus;

[0040] When the data information of multiple functional control units conflicts in the CAN bus transmission, the CAN transceiver reads and transmits according to the priority level of the data information corresponding to each functional control unit.

[0041] There are many functional control units inside the tractor. Since CAN bus transmits data information, the real-time performance, flexibility and reliability are relat...

Abstract

The invention relates to a CAN (controller area network) system of a tractor and a data information transmission method. The CAN system comprises a plurality of function control units in the tractor, the function control units are connected through a CAN bus, and a CAN transceiver is connected to the CAN bus. When data information of the function control units conflicts during CAN bus transmission, the CAN transceiver reads and transmits the data information according to priority levels of the data information corresponding to the function control units. The CAN system of the tractor and the data information transmission method have the advantages that a CAN network is constructed according to the function control units in the tractor, and through the CAN bus, real-time performance, flexibility and reliability in data information transmission are quite high; the data information of the function control units are transmitted through the CAN bus according to the priority levels, so that data information conflict is avoided, and the data information can be transmitted in order.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a tractor dual CAN system and a data information transmission method. Background technique [0002] There are many functional control units inside the tractor. To realize the interactive transmission of information between these functional control units, at present, the two functional control units that need to be interacted are mainly connected through lines, and the line installation is complicated; in addition, when the tractor internal When multiple functional control units of the system perform data interaction at the same time, it is confusing. Contents of the invention [0003] The invention provides a tractor CAN system and a data information transmission method, which adopts priority for transmission, avoids data information conflicts, and enables data information to be transmitted in an orderly manner. [0004] The technical solution of the present invention to...
