Advantages of fiber transmission CAN tool
CAN bus is also called controller area network. It is a kind of industrial communication bus developed by German Bosch company, that is, control communication system. Because of the need to adapt to the needs of modern large-scale industrial production, the CAN bus has the following characteristics by nature:
1. Fast data transmission speed and long data transmission distance. The maximum baud rate of the CAN bus is 1000Kbps (within 40 meters), and the minimum baud rate is 5Kbps (10 kilometers). 2. There are many connectable node devices and strong anti-interference ability. The CAN bus uses shielded twisted pair tea powder voltage signals to transmit data, which will not easily cause the collapse of the connected nodes. One CAN bus can connect 110 nodes at the same time, and they are not unified with each other and will not interfere with each other.
3.CAN bus maintenance cost is low, cost-effective. Because its performance is stable and excellent, and it is not easy to be damaged, the maintenance cost of the CAN bus is relatively low, and there is no need for frequent maintenance. Overall cost-effective.
The above are some of the significant advantages of the CAN bus, but it is also because of its excellent characteristics that many industrial production areas will use it, such as tram control, fire engine networking and so on. But we have improved above. The baud rate of the CAN bus is only relatively high within 40 meters and exceeds a certain distance, and its data transmission speed may not meet the actual needs. But at the same time, its excellent anti-interference ability is not replaced by other buses. Therefore, we need to relay the CAN bus, that is, the CAN bus can maintain a fairly fast data transmission speed over a distance of more than 40 meters. This operation is necessary in areas such as the construction of cross-sea bridges. Of course, a more common example is the construction of a fire engine mainframe networking system. After all, the fire protection industry cannot afford to delay. Looking at all kinds of relay methods comprehensively, it is undoubtedly more suitable to use optical fiber for CAN bus data relay, and it is more flexible to apply, especially after using the optical fiber transmission can tool GCAN-208 of Shenyang Guangcheng Technology. Let ’s briefly introduce this useful tool.
Shenyang Guangcheng Technology GCAN-208 optical fiber transmission can tool is integrated with 1 (or 2) standard optical interface (single-mode, multi-mode, SC, ST optional), 2 (or 1) standard CAN bus interface Industrial CAN bus to fiber converter. GCAN-208 series optical fiber transmission can tool can convert CAN bus data into optical signals for transmission through optical fiber. By using GCAN-208 series optical fiber transmission can tools in pairs, users can easily extend the CAN bus communication distance, effectively eliminate long-distance communication interference, and prevent the bus from being affected by electromagnetic interference, ground loop interference, and lightning strikes on the bus and equipment. damage.
