Description
Technical field
This utility model belongs to communication technique field, particularly relates to a kind of adapter based on embedded ethernet.
Background technology
In communication technique field, there is the skimble-scamble drawback of data-interface mode that instrument provides, in order to efficiently solve this contradiction, the adapter of integrated multiple data-interface arises at the historic moment.The major function of adapter has been data conversions, by the data signal of Real-time Collection, to grid convert data signal.Conventional adapter, owing to being fettered by close network, is not easy to remotely monitor instrument.
Utility model content
This utility model provides a kind of adapter based on embedded ethernet for deficiency of the prior art, this adapter uses Embedded Computer On Modules and Ethernet to combine, on the one hand improve data access speed, on the other hand rely on the Internet to realize the seamless link with PC.
For solving above-mentioned technical problem, this utility model is addressed by following technical proposals:
A kind of adapter based on embedded ethernet, it is characterized in that, including PC/104 mainboard, relay module, serial port module and power transfer module, described PC/104 mainboard comprises processor, serial communication interface, Ethernet interface, power-switching circuit and control circuit, it is integrated with two Intel8255X ethernet controllers on described PC/104 mainboard processor, described ethernet controller carries out data by Ethernet interface with extraneous network, information exchanges, described PC/104 mainboard is connected with serial port module by serial communication interface, described PC/104 mainboard is connected with relay module by control circuit, described PC/104 mainboard is connected with power transfer module by power-switching circuit.
Especially, described Ethernet interface is two-way 10/100M Ethernet interface.
The beneficial effects of the utility model and advantage are: this utility model uses PC/104 mainboard, and modularity and integration degree are greatly improved, and enhance testability, make full use of PC/104 internal RAM, improve data access speed.PC/104, as the one of built-in PC, has the open bus-structured feature of PC, can develop different functional cards, to adapt to distinct device requirement.Ethernet has the advantages such as networking is easy, transmitted data amount is big, speed is fast, and this adapter has Ethernet interface, completes the information exchange with external network.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Shown by reference numeral: 101 PC/104 mainboards, 102 relay module, 103 serial port module, 104 power transfer module.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
nullAs shown in Figure 1，This utility model provides a kind of adapter based on embedded ethernet，Including PC/104 mainboard 101、Relay module 102、Serial port module 103 and power transfer module 104，PC/104 mainboard 101 comprises processor、Serial communication interface、Two-way 10/100M Ethernet interface、Power-switching circuit and control circuit，Two Intel8255X ethernet controllers it are integrated with on PC/104 mainboard 101 processor，Ethernet controller carries out data by two-way 10/100M Ethernet interface with extraneous network、Information exchanges，PC/104 mainboard 101 is connected with serial port module 103 by serial communication interface，PC/104 mainboard 101 is connected with relay module 102 by control circuit，PC/104 mainboard 101 is connected with power transfer module 104 by power-switching circuit.
Two Intel8255X ethernet controllers on PC/104 mainboard 101 can work in full duplex or half duplex mode, and in a full-duplex mode, 8255X follows IEEE802.3 flow control specification.CSMA/CD unit in 8255X enables it to be connected with the Ethernet of 10 or 100Mbps.CSMA/CD unit has all functions of 802.3 agreements, such as clash handle, extension interface channel etc..CSMA/CD unit also may operate under semiduplex mode, can transmit simultaneously and receive.
When adapter does not powers on, relay module 102 is in normally off, directly it is connected with device information interface unit, after adapter powers on, ethernet controller is initialized by PC/104 mainboard 101, i.e. set adapter IP address, physical address, gateway and port numbers in a network, according still further to TCP/IP (TransmissionControlProtocol/InternetProtocol) agreement, data message is packaged into IP report, drive ethernet controller that IP is reported and submitted master station, it is achieved the transmission of data, information and conversion.
