CAN fiber optic data conversion repeater
The CAN bus is a widely used field bus. We can see it in the fields of automobile control, fire fighting host networking, and industrial automation control. The data transmission speed of the CAN bus is relatively fast, and it can reach 1000Kbps within 40 meters. It also has a good multi-node connection capability and super anti-interference. However, the CAN bus is not perfect, and its effective data communication distance is somewhat inadequate in the current use environment, especially when facing the construction of cross-sea bridges, inland train tunnels and other projects. Since this type of bus has excellent performance, but also has obvious shortcomings, how should we choose? In general, there are two ways to go. First, look for another new field bus with all attributes stronger than the CAN bus. It sounds one step, but for now, this bus has not been developed, or Even if there are, the high cost of its use makes us have to give up. The second way is to solve the problem that the effective data transmission distance of the CAN bus is close. We concentrated on solving this problem. Isn't it all right? Relatively speaking, this problem is better solved and the cost is lower. It is also the reason why various types of repeaters that extend the CAN data communication distance have sprung up. Today, let's talk briefly about the CAN optical fiber data conversion repeater that uses light as a relay medium.
From the name, we can see that the connection line of the CAN optical fiber data conversion repeater is optical fiber, and the carrier of information transmission is naturally light. Because it relies on optical fiber connection equipment, then this way of data transmission can achieve very remote information arrival. Why? You can think about, what is the communication connection between continents and continents? Submarine cable. What is inside the submarine cable? optical fiber. You understand this time. Moreover, because the speed of light is the fastest speed in the world, then using fiber optic cable as a relay medium, there must be no need to say in terms of communication speed. In addition, the optical fiber is generally not exposed in the air. It is unknown how many layers of insulation are wrapped on the outside. This physical isolation method makes the external electromagnetic interference seem helpless, further improving the security of information transmission.
From the above introduction, we can see that the CAN optical fiber data conversion repeater is indeed a very ideal CAN data relay device. Of course, if you say that you have encountered a situation where the natural environment is bad and it is not easy to wire, then I can only say that I can find a way to lay it out. If the situation is really bad enough, I can change the wireless to CAN repeater. , CAN fiber optic data conversion repeater is not omnipotent, you can not ask it to do everything, if it is really like that, what other types of CAN repeater do? We continue to talk about CAN fiber optic data conversion repeaters. Because of the powerful functions of this tool, many manufacturers have invested in the research of related equipment. Among them, Shenyang Guangcheng Technology's GCAN-208 series CAN optical fiber data conversion repeater is particularly excellent. Below, we will introduce it.
Shenyang Guangcheng Technology GCAN-208 series CAN optical fiber data conversion repeater is integrated with 1 (or 2) standard optical fiber interface (single mode, multimode, SC, ST optional), 2 (or 1) standard CAN Industrial grade CAN bus to fiber converter with bus interface.
Shenyang Guangcheng Technology GCAN-208 series CAN optical fiber data conversion repeater can convert CAN bus data into optical signal and transmit through optical fiber. By using the GCAN-208 series modules in pairs, users can easily extend the communication distance of the CAN bus, effectively eliminate long-distance communication interference, and prevent the bus from being damaged by electromagnetic interference, ground ring interference, and lightning strikes.
Shenyang Guangcheng Technology GCAN-208 series CAN fiber optic data conversion repeater can convert CAN bus data transparently and losslessly into optical signals, and then parse the optical signal transparently and losslessly into CAN bus data. Guangcheng Technology uses a unique bus signal conversion technology, which can convert the conversion time between CAN data and optical signals to the microsecond level, which ensures the real-time communication, so GCAN-208 can support any CAN bus communication protocol Such as: CANopen, SAEJ1939, DeviceNet, NMEA2000, etc.
