Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is elaborated:
As shown in Figure 1, the switch of present embodiment comprise a core Switching Module 2, with Switching Module 2 processor module 3, static memory 6, Flash module 7 and a plurality of port module 1 that connect of two-way communication mutually, wherein, Switching Module 2 is used for receiving data from port module 1, behind Switching Module 2, if need not to carry out data processing, send from the corresponding port converting suitable data type to; If the data that receive need be handled, then Switching Module 2 is sent to processor module 3 with data, is forwarded to Switching Module 2 again after the data of 3 pairs of receptions of processor module are handled, and Switching Module 2 sends data again by corresponding ports.
Particularly, in the present embodiment, port module 1 comprises signal of telecommunication access interface 11 and light signal access interface 12, signal of telecommunication access interface 11 is realized exchanges data with Switching Module 2 by being connected buffer circuit 4 between itself and the Switching Module 2 after with extraneous high voltage, interference signal filtering, and light signal access interface 12 will be realized exchanges data by the interface conversion circuit 5 that is connected between itself and the Switching Module 2.Signal of telecommunication access interface 11 comprises twisted-pair feeder port 111, M12 splice port 112, D-SUB splice port 113, and wherein, twisted-pair feeder port 111 is a kind of transmission mediums the most frequently used in the generic cabling engineering.Twisted-pair feeder is entwined mutually by two 22～No. 26 insulated copper leads.By two copper conductors that thoroughly do away with edge are twisted together mutually by certain density, can reduce the degree that signal disturbs, the electric wave that the electric wave of each root lead radiation in transmission also can be sent on other single line is offset.Twisted-pair feeder is compared with other transmission mediums, all be subjected to certain restriction at aspects such as transmission range, channel width and data transmission baudss, but price is comparatively cheap, and it is bad, and to be limited in the general Fast Ethernet influence very little, so twisted-pair feeder is still transmission medium first-selected in the intranet at present,, the switch in the present embodiment is used for the port that twisted-pair feeder inserts so being provided with.
The M12 joint has formed the jointing of a standard, the M12 splice port 112 that is complementary with the M12 joint that is provided with the switch of present embodiment can realize the fixing that is connected, make data physical link in transmission course can not cause loss of data because of loose contact, and its can realize preventing dust, the function of shockproof, waterproof, can assemble STP netting twine (Shielded Twisted Pair) at this joint, guarantee that transfer of data is not subjected to the EMI electromagnetic interference.The integrality of transfer of data also significantly improves.
Described D-SUB splice port 113 is exactly the interface of we RS-232 that uses always, because M12 is on the high side market, be in the consideration on the cost, use cheap D-SUB under a lot of situations and substitute M12, its shockproof, dustproof effect is also very good, the universal face in market is very wide, so be used in very industrial a lot of occasions.
Light signal access interface 12 comprises SFP light mouth 121 and 1 * 9 optical fiber interface 122, wherein, SFP light mouth 121 can insert dissimilar optical modules, realize the feasibility of module variation conversion, its hot plug function is in the normal operation that can guarantee equipment, realize the conversion between disparate modules, greatly facilitate the operation of industry spot.
1X9 optical fiber interface 122 is exactly our the most frequently used optical fiber communication module, and it is because model is various, and moderate cost is widely used in industry spot.Why optical fiber communication is subjected to people's very big attention, and this is because compare with other means of communication, has beyond challenge superiority.Because optical fiber has extremely low decay coefficient, and its repeater span is reached more than the several hundred kilometers.Only carry out when light wave transmits in optical fiber, do not have light " leakage " to go out basically, so its security performance is fabulous in its core district.And the signal of its communication is light signal, is not afraid of the interference of extraneous strong-electromagnetic field, and corrosion-resistant, pliability is strong etc., and characteristic makes its The field in industry more extensive.Therefore, in order to adapt to the needs of industry spot, switch being provided with of present embodiment is used for the optical fiber interface 122. that optical cable inserts
From present Ethernet status of development, the Industrial Ethernet switch is applied in very long from now on a period of time universalness more, variation industrial circle.In the face of a lot of particularity of industry spot, the interface shape of the network switch is more variation also, and the utility model variation Interface design makes that the communication between the distinct device can realize easily, has bigger market using value.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this technology can understand content of the present utility model and is implemented; can not limit protection range of the present utility model with this; all equivalences of doing according to spirit of the present utility model change or modify, and all should be encompassed within the protection range of the present utility model.
