The described configurable cascade circuit of mining Ethernet, described switch management unit is connected with microprocessor and Ethernet switch unit respectively by SPI interface.
The described configurable cascade circuit of mining Ethernet, described ethernet PHY unit is made up of ethernet physical layer chip and peripheral circuit thereof.
The described configurable cascade circuit of mining Ethernet, described Ethernet switch unit comprises ethernet controller, ethernet transceiver and light transmit-receive integrated circuit.
The described configurable cascade circuit of mining Ethernet, described switch management unit is made up of memory chip and peripheral circuit thereof.
The described configurable cascade circuit of mining Ethernet, described expansion interface circuit comprises that switching value output port, switch acquisition port, frequency quantity gather port, CAN communication interface, LIN communication interface, RS485 communication interface.
As shown from the above technical solution, the utility model is by arranging ethernet PHY unit and Ethernet switch unit, Ethernet interface and Ethernet cascade function can be provided, facilitate in mining equipment access mine Ethernet, expand the range of application of mining equipment, reduce the input of mining Ethernet switch, greatly reduced equipment investment and construction cost; By switch management unit is set, can carry out VLAN division to network as required, restrictive ports bandwidth or close unnecessary port, and carry out Port Mirroring, thus guarantee transmission channel bandwidth; By expansion interface circuit is set, can conveniently expand multiple interfaces, the equipment of realizing access polytype equipment and dissimilar fieldbus merges.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Further illustrate the utility model below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, the configurable cascade circuit of a kind of mining Ethernet, comprises microprocessor 1, ethernet PHY unit 2, Ethernet switch unit 3, switch management unit 4 and expansion interface circuit 5.Ethernet PHY unit 2 is connected with microprocessor 1 is interactive by MII interface, is connected with Ethernet switch unit 3 is interactive by Ethernet interface.Switch management unit 4 is connected with microprocessor 1 and Ethernet switch unit 3 interactive modes respectively by SPI interface.Expansion interface circuit 5 is connected with microprocessor 1 is interactive.Ethernet PHY unit 2 is made up of ethernet physical layer chip and peripheral circuit thereof.Ethernet switch unit 3 comprises ethernet controller, ethernet transceiver and light transmit-receive integrated circuit.Switch management unit 4 is made up of memory chip and peripheral circuit thereof.Expansion interface circuit 5 comprises that switching value output port, switch acquisition port, frequency quantity gather port, CAN communication interface, LIN communication interface, RS485 communication interface.
Operation principle of the present utility model:
Ethernet PHY unit 2 is connected with the Ethernet control end of microprocessor 1 by MII interface, forms an Ethernet interface.Ethernet switch unit 3 is by ethernet controller, ethernet transceiver and light transmit-receive integrated the electric circuit constitute, produce two 10/100M self adaptation Ethernet electrical interfaces and two 100M Ethernet optical interfaces, one of them Ethernet electrical interface and the Ethernet interface communication being made up of ethernet PHY unit 2 and microprocessor 1, other interface is used for articulating ethernet device.The configuration order that microprocessor 1 is received by SPI interface is sent to switch management unit 4, and switch management unit 4 is again by SPI interface configuration managed ethernet switch unit 3.Can carry out VLAN division to network as required, restrictive ports bandwidth or close unnecessary port, and carry out Port Mirroring, thus guarantee transmission channel bandwidth.Expansion interface circuit 5 is connected in the input/output interface of microprocessor 1, can expand as required, can expansion switch amount output port, switch acquisition port, frequency quantity gather the circuit such as port, CAN communication interface, LIN communication interface, RS485 communication interface.
From the above, the utlity model has two 10/100M Ethernet electrical interfaces and two 100M Ethernet optical interfaces, can articulate ethernet device simultaneously, and can be configured Ethernet interface parameter by microprocessor.The utility model can be integrated in mining equipment easily, make mining equipment there is Ethernet interface, thereby can directly access mine looped network or by accessing again after network interface cascade in mine looped network, effectively strengthen flexibility, practicality and the economy of mining equipment.
The above execution mode is only that preferred implementation of the present utility model is described; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model, all should fall in the definite protection range of claims of the present utility model.
