Because the communication of products is very important, Can communication protocol can realize communication with only two lines because of its long communication distance, and the devices that need communication only need to be connected to two lines respectively, so in the current electronic Among the products, there are many electronic products that communicate with CAN.

Communication between people requires language, a machine is composed of several controllers, and these controllers also need to communicate to complete a job. Machine communication can only be achieved through voltage changes, that is, high voltage represents 1, and low voltage represents 0. How can I make a machine that can only speak between 1 and 0? Here we think of the previous telegram.

During the war, all communications use radio tick-tick telegrams to transmit messages. If you don’t know the telegram message protocol of the other party, even if you intercept the specific content of the other party’s message, you will not know what it means. Therefore, the CAN message is also evolved from the telegram message, that is, using the level of 1 and 0, plus the corresponding meaning of these numbers, the can message protocol is formulated.

Features of the CAN protocol include complete serial data communication, real-time support, transmission rates up to 1Mb/s, 11-bit addressing and error detection capabilities.

Applications in automobile manufacturing, applications in large-scale instruments and equipment, applications in industrial control, applications in smart home and living community management, and applications in robot network interconnection. At the same time, due to the characteristics of the CAN bus itself, its application scope is no longer limited to the automotive industry, but to automatic control, aerospace, navigation, process industry, machinery industry, textile machinery, agricultural machinery, robots, CNC machine tools, medical equipment. and sensor development. CAN has formed an international standard and has been recognized as one of the most promising field buses.
