What is the Difference between Lin Bus and CAN Bus
1. Different meanings
CAN bus system: CAN belongs to the category of field bus, which is a serial communication network that effectively supports distributed control or real-time control. Compared to many RS-485 R-line based distributed control systems.
LIN bus system: LIN bus is a low-cost serial communication network defined for automotive distributed electronic systems. Applications that do not place high demands on the bandwidth, performance, or fault tolerance of the network.
2. The transmission rate is different
CNA bus system: The bit rate of the CAN bus is relatively high, usually 500kb/s when used in automobiles, and the lowest is 100kb/s.
LIN bus system: The highest bit rate of LIN bus is 2Okb/s, usually 19200b/s or 9600b/s.
3. The system structure is different
CNA bus system: CAN bus is a multi-host system, that is, any electronic unit connected to the bus can obtain bus control through bus arbitration, and send information to the bus system. When the unit sends out a complete ID, it is host. The CAN bus uses 11-bit IDs (or even more), allowing more units in a subsystem.
LIN bus system: LIN bus is a single-master multi-slave system. There is only one master in each subsystem. All information transmission is controlled by the master. The slave must wait for the master to send out the ID corresponding to it. send Message. The LIN bus uses a 6-bit ID and can only have fewer units in a subsystem.
