Abstract

An embodiment of the invention discloses CAN communication converting equipment which comprises two CAN drivers. The CAN communication converting equipment can be connected with two CAN networks simultaneously. When network nodes in different CAN networks need to exchange data, the CAN communication converting equipment can be used for sending the data needing to be exchanged to a computer. Thus, the burden of the network nodes is reduced, and the power consumption of the network nodes is reduced. The CAN communication converting equipment can achieve conversion between CAN signals and other signals and further achieve communication between the network nodes in the different CAN networks. The embodiment of the invention further provides a communication system.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to a CAN communication conversion device and a communication system. Background technique [0002] CAN network, that is, controller area network, is one of the most widely used field buses in the world. In practical applications, the CAN network is often mixed with other networks, which requires the conversion of CAN signals into other signals, such as serial port signals. The identification of converting CAN signals into other signals is called CAN communication conversion equipment. [0003] In the process of implementing the present invention, the inventor found that the existing CAN communication conversion equipment has a single function and can only realize the conversion between CAN signals and other signals. Contents of the invention [0004] The purpose of the present invention is to provide a CAN communication conversion device to increase...
