Functional overview

The CAN bridge (Bridge) is an intelligent repeater. By using CAN bridge to interconnect the equipment, the physical limit of the number of CAN bus nodes and communication distance is overcome, and the total number of nodes in the CAN network can be effectively extended and the communication distance can be extended.
In a CAN bus network, a bridge can receive signals from a cable, amplify them, and send them to the next cable. Therefore, it can not only extend the communication distance or range of CAN networks, but also improve the performance, reliability and security of CAN networks.
The storage and forwarding functions of the CAN bridge can be applied to two CAN networks that connect different baud rates of CAN. Thus, a CAN network with a different rate is matched and mixed together to form a hybrid network.
CAN bridge is a storage and forwarding device that connects two CAN networks. It can provide intelligent connection service. It can be selectively received and forwarded according to the ID filtering of the message frame. Networks 1 and 2 through the bridge connection, the bridge receives 1 network packets sent to check frame information in the data packet, if the information does not meet the requirements of network frame 1, it will give up, instead, if they meet the 1 requirements for the 2 network and network information needs, it will continue to send to the network 2. In this way, the CAN bridge can be used to isolate information and isolate the information that does not meet the requirements of the network to prevent the inefficient information from occupying the bus resources.
Using a CAN bridge to segment a larger CAN network into several segments helps improve network reliability, availability, and security.
As a transparent bridge, the CAN bridge has the advantage of being easy to install and easy to use. It is a plug and play device. The use of CAN bridges requires no changes to existing hardware and software without changing the existing network parameters. Just plug in the cables and have no effect on the running of the existing CAN network.

Typical applications

1) when two different baud rate CAN networks need to be connected, the CAN bridge can be used to configure 2 CAN channel baud rates independently and realize the connection.
2) when the devices communicate with each other through the CAN bus, but the communication distance exceeds the distance limit of the CAN bus, the relay function of the CAN bridge is used to amplify the signal and maintain the stability and safety of the CAN network.
3) the CAN bus has a large amount of data and needs to be filtered by the CAN bridge when it needs to receive the CAN information selectively.
4) when the number of nodes in the network is relatively large, the network nodes are expanded.
