Digital business more emergency communication system based on the FPGA design and implementation

摘要

This paper expounds the digital multi-service emergency communication system based on FPGA design scheme and the design process, the system can realize the video transmission via optical fiber (or wireless), such as telephone and Ethernet remote communication. The actual application topology is given. Design the network video module, telephone gateway module, Ethernet switching module, transmission module and power supply module circuit and signal process. Application of FPGA technology, selection of ALTERA corporation Cyclone II series chips, in Quartus II software platform to complete the MAC design of the key technology, Ethernet switching module. Mainly introduces the gigabit network exchange module realization process. The technical parameters in line with the national standard, and the reliability of the system are verified by simulation experiments. For the rescue and relief and field rescue and other emergency, provide the reliable and portable communication solutions.
