| Abstract: | Considering the higher requirements of field bus raised by industrial control domain in the respects of transmission distance, Electro-Magnetic Interference resistance and bus bandwidth, IEEE1394b-PCI fiber interface card with function of fault diagnosis was developed. The optical bus system was established based on the fiber interface card. From the experimental results of video transmission diagram of optical bus and analysis of experiment data, it can be concluded that the fiber interface card can meet the needs of practical applications. At the same time, the optical bus system can realize fault location and is easy for maintenance. |
