Abstract

The invention provides a multipath network extension module, which mainly comprises a high-speed main board connector, a buffer, an LED (Light-Emitting Diode) indicator, multiple network cards and multiple network output connectors, wherein the high-speed main board connector is connected with the buffer; the buffer is simultaneously connected with the multiple network cards and the LED indicator lamp; each network card is connected with a network output connector. Compared with the prior art, the multipath network extension module has the advantages that multipath gigabit Ethernet extension is implemented in a CPCI (Compact Peripheral Component Interconnect) system; a connector and module combination design is adopted, so that system design complexity is effectively reduced, and a design risk is shared by the two board cards; by a modular design, system design maintainability is improved; by an external module design, multiple paths of network cards can be extended on a limited space of a main board; by an independent module design, system design cost is effectively reduced, and system extensibility is improved.

Description

technical field [0001] The invention belongs to the technical field of CPCI integrated systems, and in particular relates to a multi-channel network expansion module. Background technique [0002] Network communication is widely used in industrial control, and multi-network application in CPCI system is also very important. Each CPCI board manufacturer has its own 3U and 6U multi-network expansion cards. However, due to the limited bandwidth of the CPCI bus itself, the network expansion cards based on the CPCI bus generally can only achieve 100M network, and cannot realize the real precursory Ethernet. [0003] Now, with the development of digital technology, we need to transmit more and more data in the network, and the speed of 100M network is difficult to meet the application requirements. The implementation of Gigabit network in the CPCI system has become an important part of system design. Contents of the invention [0004] In view of this, the present invention aim...
