Long Distance Communication Solutions
In modern automotive electronics, industrial automation and aerospace applications, where the requirements for communication reliability and transmission distance are constantly increasing, CAN (FD) buses are widely used as an important communication technology.
However, in large-scale factories, decentralized systems and remote monitoring scenarios, the communication distance of traditional CAN (FD) buses is limited. In order to meet the practical application requirements, the research and realization of CAN (FD) bus long-distance communication technology has become an important topic. With the increasing demand for remote communication in the intelligent development of automotive electronics, the expanding scale of factories and dispersed equipment in industrial automation, as well as the difficulty of wiring in the aerospace field and the high reliability requirements, all of these have prompted the continuous exploration and application of CAN (FD) bus long-distance communication technology.
A simple CAN (FD) communication application scenario is shown below: In some environments, the maximum communication distance between the vehicle data and the controller chip is only about 20 m at a baud rate of 500 kbps to 2 Mbps, and if it is forced to be extended to 40 m, the communication may fail due to problems such as signal degradation.
HONGKE's PCAN-Router series gateways can be used as signal repeaters in CAN (FD) bus long-distance communication to avoid signal degradation problems during transmission. In addition, the device supports customized programmable gateway firmware, which can filter the bus signals and reduce the bus load to ensure the stable transmission of CAN (FD) bus signals.
The PCAN-Ethernet Gateway series can effectively convert CAN (FD) signals into Ethernet signals and encapsulate them into TCP/UDP messages for transmission. In long-distance communication scenarios, it can effectively reduce the interference of the communication environment and greatly improve the transmission distance of CAN (FD) bus signals.
The PCAN-LWL can replace any segment of the CAN (FD) bus with a fiber-optic link to ensure bus communication quality and extend the communication distance. It is also widely used in EMC test scenarios.
Similarly, the transmission distance of the LIN bus can be extended by means of gateways or optical signal conversion.
For LIN bus, the transmission distance can also be extended by using gateway or optical signal conversion.
