Multi-card high-speed interactive communication module and system based on serial bus

Abstract

The invention relates to a multi-sub-card high-speed interaction type communication module and a multi-sub-card high-speed interaction type communication system based on a serial bus. The multi-sub-card high-speed interaction type communication module comprises a communication interface unit, a main sub-card unit, an outer control interface unit and a power supply unit, wherein the communication interface unit comprises an uplink interface and n downlink interfaces; n is a positive integer greater than or equal to 1; the main sub-card unit is connected with the n downlink interfaces; the outer control interface unit is connected with the main sub-card unit; the power supply unit is used for supplying power for the communication interface unit, the main sub-card unit and the outer control interface unit. By adopting the structure, the multi-sub-card high-speed interaction type communication module and the multi-sub-card high-speed interaction type communication system based on the serial bus are simple in structure, high in data throughput rate, diverse in interaction mode and good in expandability and can be widely applied to electronic communication equipment systems, synchronous communication of a plurality pieces of equipment can be achieved, and an interaction communication way can be built for the host computer and peripheral auxiliary equipment.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to communication equipment, and in particular to a multi-subcard high-speed interactive communication module and system based on a serial bus. Background technique [0002] With the rapid development of electronic communication technology, for example, wireless communication technology has been upgraded from the 2G era to the 4G era in just a few years, and 5G technology is also maturing. In order to achieve ultra-high-speed data transmission, communication manufacturers will adopt large-scale multi-antenna technology. Therefore, when using traditional measuring instruments such as two-port and four-port vector network analyzers for measurement during the development and production of these multi-port communication equipment, they must endure other problems. There are many shortcomings such as slow measurement speed, bulky size, complicated wiring, difficult operation,...

Problems solved by technology

In order to achieve ultra-high-speed data transmission, communication manufacturers will adopt large-scale multi-antenna technology. Therefore, when using traditional measuring instruments such as two-port and four-port vector network analyzers for measurement during the development and production of these multi-port communication equipment, they must endure other problems. There are many shortcomings such as slow measurement speed, bulky size, complicated wiring, difficult operation, and high technical requirements for R&D and production personnel, and the general use of PCA bus or ISA bus, port cascading will be limited, and the distance of data transmission is short, etc. Lead to low efficiency in R&D and production, and may eventually miss the best time for products to be put into the market
