Embodiment

Please refer to Fig. 1, system block diagrams for network connectivity module 80 of the present invention, include: network port 10a, network port 10b, detecting unit 20, switch unit 30, computing module 70, can be to electronic equipment, for example server system, home computer, intelligent home electrical appliance etc. provide the function of network redundant line, and then make the running of system held proper network line.

Network terminal 10a, be preset as in order to provide electronic equipment to connect the connecting interface of world-wide web, for in the electronic equipment default main connect world-wide web connecting interface, wherein network port 10a be for can be used in Ethernet (Ethernet) transmit port of TCP/IP network communication and transmission protocol infrastructure, or is used for the communication protocol framework of optical fiber (fiber) transmission.

Network port 10b, also can provide electronic equipment to connect world-wide web or in order to the connecting interface network port of another network connectivity module, wherein network terminal 10b be for can be used in Ethernet (Ethernet) transmit port of TCP/IP network communication and transmission protocol infrastructure, or is used for the communication protocol framework of optical fiber (fiber) transmission.Here be preset as the connecting interface that connects another network connectivity module.

Computing module 70 is integrated on the chip, and chip is embedded in the network connectivity module 80, handles computing via the network connectivity data that network port 10a or network port 10b import into, is conveyed in the processor 90 of electronic equipment again.

Detecting unit 20 is in order to survey the data (data) through switch unit 30, if 70 runnings of detecting unit 20 detection calculations modules are normal, then, will further process computing, be sent in the electronic equipment again by computing module 70 by the data of network port 10a transmission.If detecting unit 20 detects unusual reaction, may be that an assembly takes place unusual in the computing module 70, then represent network connectivity module 80 generation problems, send control signal by detecting unit 20 immediately and give switch unit 30, make switch unit 30 can switch to network port 10b and continue to receive by the next data of another network connectivity module.

Switch unit 30 is arranged between network port 10a, network port 10b and the microprocessor 40.When abnormality appears in network connectivity module 80, detecting unit 20 can produce a control signal and give switch unit 30.The control signal that switch unit 30 is produced according to detecting unit 20, switch network port 10a or network port 10b that electronic equipment connects, so that electronic equipment is connected to another network connectivity module by network port 10a or network port 10b, wherein select switch unit 30 to reach the action demand by multiplexer (Multiplexer).In Fig. 1, the default line path of switch unit 30 is network port 10a, and the line path of redundant is network port 10b.Certainly, signal has only the situation of two network ports among Fig. 1, if the network port situation more than two is as the same, one in order to connect world-wide web, and other network port then connects several network connectivity modules.Switch unit 30 can automatically switch to the network connectivity module that can be used for line, and receives by redundant network connectivity resume module data later.

Please refer to Fig. 2, workflow diagram for detecting unit 20 in the system of the present invention, signal is begun by step, just can detect control via detecting unit 20, in step 200, signal is no abnormal, then detecting unit 20 does not transmit control signal, continue detection system, if abnormal signal, then detecting unit 20 enters in the step 201 and transmits control signal.In the step 202,, produce switching signal according to the control signal order, after switch unit 30 receives switching signal, handover network line path.

Yet the promotion and implementation of the method are to be used for throwing the net the network link module more, please refer to Fig. 3.Fig. 3 is used for the implementation system calcspar of two network connectivity modules for the application, and when the first network connectivity module 81 broke down, electronic equipment still can continue to connect networks by the second network connectivity module 82.

Among Fig. 3, system block diagrams of the present invention, comprise outside the first network connectivity module of being formed by first network port 11a, second network port 11b, first detecting unit 21, first switch unit 31, first computing module 71 81, add one again and comprise the second network connectivity module of being formed by the 3rd network port 12a, the 4th network port 12b, second detecting unit 22, second switch unit 32, second computing module 72 82.If in the first network connectivity module 81, the running of first computing module, 71 hardware takes place unusual, then send control signal by first detecting unit 21 immediately and give first switch unit 31, make first switch unit 31 can open the line of second network port 11b, second network port 11b is connected by grid line with the 3rd network port 12a, after connection, the data-signal that can be transmitted into by the 3rd network port 12a is through second switch unit 32, do calculation process by second computing module 72 again, be sent to the microprocessor 91 in the electronic equipment afterwards, so, the network data that is received by network 11a just can take place under the unusual situation at first computing module 71 smoothly, still can enter the microprocessor 91 in the electronic equipment, to reach the function of network redundant.Identical, if electronic equipment is wanted dateout, then follow the same paths of data input, earlier do calculation process by second computing module 72, be sent to the 3rd network port 12a afterwards, be sent to second network port 11b by grid line again, 91 data of the microprocessor in the electronic equipment transmitted the network that reaches the outside by first network port 11a again through first switch unit 31.

All has the independent function that receives data as 80, the first network connectivity modules 81 of network connectivity module among Fig. 1 and the second network connectivity module 82.If the second network connectivity module 82 is when breaking down, electronic equipment also can continue to connect networks by the first network connectivity module 81.On the network link module, provide more stable electronic equipment network connectivity redundant yet the method also can be used for throwing the net more, the slot of a plurality of network connectivity modules of energy device also need be provided in the electronic equipment.

By this network connectivity backup system, when the network connectivity generation problem of electronic equipment, the line path of a redundant can be provided, electronic equipment is carried out the change action in network connectivity path, keeping the network connectivity ability of electronic equipment, to improve electronic equipment or some need apply to the reliability and the stability of the electronic equipment of network connectivity.

Though the present invention discloses as above with aforementioned preferred embodiment; yet it is not in order to limit the present invention; any those skilled in the art without departing from the spirit and scope of the present invention, when can making a little variation and remodeling, so protection scope of the present invention must be looked this specification claims and is as the criterion.
