Technical field
The utility model relates to a kind of self adaptation Ethernet and reinforces switch, and storage, transfer and exchange for information under severe environmental conditions, realize ethernet communication function.It can provide the electrical signal paths exclusively enjoying for any two network nodes of access.It realizes communication between system equipment, completes each equipment room information exchange, realizes the ethernet communication function of each equipment room.
Background technology
The world today is the epoch of a communication technology high speed development, and switch is also more and more universal.The most working temperature of switch is in the market 0 ℃～40 ℃, and the mean free error time is 335h.But the remote districts severe in environmental condition, day and night temperature is larger, the work that these switches can not be good, will affect the memory transactions of information like this.Store-and-forward delay is also the important embodiment of switch performance in addition, and general switch time delay is all in 5ms at present, and port number is few, cannot meet the demands.
Summary of the invention
The purpose of this utility model is just to provide a kind of self adaptation Ethernet and reinforces strong, the adaptable multiport reinforcement type of switch, particularly reliability gigabit switch, meets the demand that following exchange rate is fast, data volume is large.
The technical solution of the utility model: self adaptation Ethernet of the present utility model is reinforced switch and comprised central processing element, central processing element is connected with dynamic random storage chip, flash chip, clock cache chip, power supply supervisory circuit and output network interface, central processing element is connected with two Interface Expanding chips, and central processing element is all connected with output network interface by magnetic module with two Interface Expanding chips.
Described self adaptation Ethernet is reinforced switch, magnetic module with export the rc protection circuit of connecting between network interface.
Described central processing element is connected serial line interface is provided with RS-232 transceiver.
Advantage of the present utility model is mainly manifested in the following aspects:
One, the utility model provides 20 mouthfuls of 1000/10/100M self adaptation Ethernet RJ45 ports, and Gbps can reach 10Gbps.Port number is many, and exchange rate is fast, can meet the demand that following switching port is many, data volume is large.
Two, the utlity model has the function that time delay is less than 1ms and supports the packet of input to carry out error detection.
Three, the utility model is supported the function of outband management.Because outband management is by serial communication, data are only transmitted at switch with between managing with machine, so fail safe is very strong.Can detect by serial ports the operating state of each port.
Four, strong, the stable performance of strong, the reliability of the utility model anti-vibration ability, mean free error time are greater than 500h, have good anti-lightning, impact resistance.
Five. working temperature-20 ℃～55 ℃.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is general structure block diagram of the present utility model: the utility model comprises central processing element, central processing element is connected with dynamic random storage chip, flash chip, clock cache chip, power supply supervisory circuit and output network interface, central processing element is connected with two Interface Expanding chips, and central processing element is all connected with output network interface by magnetic module with two Interface Expanding chips.
Fig. 2 is protective circuit schematic diagram: at magnetic module and the output rc protection circuit of connecting between network interface.Resistance R, capacitor C and light-emitting diode D.
Fig. 3 is central processing element and RS-232 transceiver connection diagram: central processing element is connected with RS-232 transceiver.
Specifically by following design, realize: a slice switch central processing element VSC7429XJG and 2 Interface Expanding chip VSC8664IC-03.Storage chip comprises dynamic random storage chip MT47H128M8CF-25E IT:H TR and flash chip M25P128VMF6TG, in addition also has some companion chips: clock cache chip NB2309AI1DTG, power supply supervisory circuit MAX811TEUS, RS-232 transceiver MAX3232EUE, 1000base-t magnetic module HX5020NL.
As shown in Figure 1, using central processing element VSC7429 as center, on its basis, expand, comprise the flash chip of its system code of storage, the dynamic random storage chip of the operating data of storage program, the Interface Expanding chip connecting in order to obtain more RJ45 interfaces.The RS232 interface of using for system debug software and hardware, update software, administration configuration is transformed by RS-232 transceiver, simultaneity factor needs the reference clock of a plurality of high-precision 25MHz, by clock cache chip, export, when system powers on the initial stage, due to spread of voltage, system mode is unavailable, thus need external power supply supervisory circuit, for system resets.
For realizing, support serial ports to download and the function of debugging, the external RS-232 transceiver of central processing element VSC7429, realizes by this transceiver MAX3232EUE the serial ports that inner GPIO is simulated by serial ports controller and causes external circuit.
Use 1000base-t magnetic module to realize die terminals and external isolation, strengthen antijamming capability, increase signal simultaneously and extend transmission distance.Simultaneously in order to protect network interface not to be struck by lightning and overcurrent impacts; between RJ45 interface and network transformer, add protective circuit; this protective circuit is composed in series by the high ceramic disc capacitor C of anti-lightning strike withstand voltage, anti-lightning strike diode D, resistance R, guarantees to reinforce switch in boisterous use.
