Description
Technical field
The utility model relates to a kind of network interface card of domain of communication equipment, particularly relates to a kind of network interface card with a plurality of Ethernet interfaces.
Background technology
Developing rapidly of Ethernet makes its main selection that becomes many local area network (LAN) mutual contact modes, and what obtain in industrial automation control field uses very widely.As an important architecture in the industrial control system, CPCI (Compact Peripheral Component Interconnect is called for short compact PCI) groove position is very limited.Existing C PCI network interface card adopts network chip directly to link to each other with cpci bus, only can finish the most basic Ethernet and insert.Existing C PCI network interface card only has a network interface, in the face of many mouthfuls of demands of applications, can only adopt the way that increases network interface card to be solved, and this will take more expansion slot position.In case network interface card breaks down, need shutdown system to carry out the replacing of whole network interface card.Because existing general CPCI network interface card do not have the hot plug management circuit, in the time of need be changed network interface card, increase, when removing, must close whole system, otherwise can cause damage, or cause the system crash deadlock network interface card itself or mainboard.In addition, Gigabit Ethernet technology is universal all the more, and general CPCI network interface card supporting rate is low, can't adapt to the network environment of higher rate.Existing general CPCI network interface card also rests on the 100Mbps level, and when it was applied to the gigabit Ethernet network, the speed of the highest 100Mbps just became the performance bottleneck of whole network.
Because the defective that above-mentioned existing network interface card exists, the design people is actively studied innovation, in the hope of founding a kind of many interfaces network interface card of new structure, makes it have more practicality.
The utility model content
Main purpose of the present utility model is, overcomes the defective that existing network interface card exists, and a kind of network interface card of new structure is provided, and technical problem to be solved is to make it have a plurality of interfaces that can work simultaneously, thereby is suitable for practicality more.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of network interface card that the utility model proposes, it comprises bridge chip and a plurality of ethernet controller, and each ethernet controller is connected to bridge chip.
Preferable, this network interface card also comprises the electric power management circuit that is connected in described bridge chip, and the bus interface that is connected in electric power management circuit and bridge chip.Each ethernet controller of this network interface card is connected with an Ethernet interface.Described bridge chip, ethernet controller, electric power management circuit and Ethernet interface are arranged on the substrate.Described bridge chip model is PCI2050B.Described ethernet controller model is Intel82541.Described electric power management circuit has the LTC4244-1 chip.Preferable, this network interface card also comprises a mounting panel, is connected in each Ethernet interface.The quantity of described ethernet controller is 4.
The utility model compared with prior art has tangible advantage and beneficial effect.By technique scheme, the utility model network interface card has following advantage at least:
Network interface card of the present utility model can be expanded 4 gigabit network interfaces on a CPCI groove position, support the hot plug function, has not only saved the space, has improved transmission rate, has also strengthened the reliability and the reliability, maintainability, safety and human factors of system.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
