A multi-channel data signal processing method and device related to digital information transmission, adopting the following steps: A. receiving multiple data signals; B. generating data frames after packaging and processing the multiple data signals respectively, and the data frames include Corresponding channel identification; C. The data frame outputs a frame signal with a fixed bandwidth through rate adaptation; D. Performs bus pass-through processing on the frame signal, and then multiplexes it into a serial bit stream signal and sends it to the line for transmission; E. The signal is transmitted to the receiving end through the line, and corresponding demultiplexing processing is performed to generate parallel bus signals; F, the bus signals are grouped, according to the frame header search results and the channel identification of the frame signal in the bus signal, each data The signal is separated and transmitted to the data port corresponding to the channel identifier. The present invention improves line transmission bandwidth, reduces processing complexity, has flexible processing methods, and is simple to implement.
Description
technical field [0001] The present invention relates to the transmission of digital information, in particular to a multi-channel data signal processing method and device. Background technique [0002] At present, most local area networks are constructed with Ethernet. Ethernet has the advantages of low price, high reliability, good scalability, and easy management, and has become a widely configured technology. [0003] The transmission rate of Ethernet has three rates: 10Mbps, 100Mbps, and 1000Mbps, and 10 Gigabit Ethernet has not been applied on a large scale. Among these three kinds of Ethernet applications, 10Mbps and 100Mbps Ethernet are mainly used for short-distance interconnection, desktop communication, computer communication and other occasions. The current mainstream routers mainly provide Gigabit Ethernet interfaces, which are widely deployed in local area networks and further extended to metropolitan area network and wide area network applications.
