UPS communication mode 3: Controller Area Network (CAN)

CAN (Controller Area Network) is an efficient and reliable serial communication protocol for vehicle and industrial automation. Originally developed by Bosch in the 1980s, it aims to solve the problem of communication between the various electronic control units (ECUs) inside the car, such as engine control, wheel speed monitoring and air conditioning control. Because of its high anti-interference ability, good real-time performance and high data communication efficiency, CAN is gradually widely used in various embedded systems, industrial equipment and other fields.

Main content

peculiarity

High reliability: CAN has strong anti-interference ability, ADAPTS to complex electromagnetic environment, and can work stably under extreme conditions.

Real-time: The priority mechanism is adopted to ensure that applications with high real-time requirements can preferentially send data.

Multi-host architecture: CAN allows multiple nodes to access the network at the same time and supports multi-host communication.

Data rate: CAN supports different baud rates, from 10Kbps to 1Mbps, which can be selected according to actual needs.

Cost effectiveness: Due to its open design and wide application, the hardware cost of CAN is relatively low, easy to integrate, and realize the economy of the system.

Application field

Automotive: In modern cars, CAN is a standard communication protocol for connecting various ECUs, covering engine management, vehicle stability control, and airbag systems.

Industrial automation: CAN is widely used in industrial control systems, such as robot control, automated production lines, sensor networks, etc.

Medical equipment: In medical instruments, CAN is used to monitor and control various equipment to ensure the reliability and real-time data transmission.

Rail and aviation: CAN is also suitable for equipment communication in rail systems and aerospace systems.

CONCLUSION

CAN (Controller Area Network) has become the key technology of automobile and industrial network communication with its advantages of high reliability, real-time and low cost. Whether it is in the complex automotive electronic system, or in various industrial automation equipment, CAN plays an important role. As smart manufacturing and autonomous driving technologies continue to evolve, CAN will continue to demonstrate its unique value as an important communication protocol for facilitating efficient collaboration between smart devices.
