In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.The present invention being usually described and illustrated herein in the accompanying drawings is implemented
The component of example can be arranged and be designed with a variety of different configurations.Therefore, below to the reality of the invention provided in the accompanying drawings
The detailed description for applying example is not intended to limit the range of claimed invention, but is merely representative of selected implementation of the invention
Example.Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, shall fall within the protection scope of the present invention.
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
The present invention is further illustrated with specific embodiment below with reference to accompanying drawings.
As shown in Figure 1, a kind of quick bypass industrial grade switch with isolation of the embodiment of the present invention, is normally supplying
Under electricity and system health, data communication passes through RJ45_1 crystal connector-relay relay 1- network transformer
Transformer 1- analog switch Analog Switch 1- physical chip PHY1- exchange chip SWITCH- physical layer core
Piece PHY2- analog switch Analog Switch 2- network transformer transformer 2- relay relay 2-RJ45_2 water
Brilliant connector, passes sequentially through and completes data forwarding, at this point, the GPIO by CPU is controlled, makes CPU_Ctrl_SWITCH1, CPU_
Ctrl_SWITCH2 and CPU_Ctrl_RELAY is " 1 " (high level), i.e. transformer transformer 1 passes through analog switch
Analog Switch 1 is connected with physical chip PHY 1, and transformer transformer 2 passes through analog switch Analog
Switch 2 is connected with physical chip PHY 2, and transformer transformer 1 is connect by relay relay 1 with crystal
Head RJ45_1 is connected, and transformer transformer 2 is connected by relay relay 2 with crystal connector RJ45_2.
Under equipment in the electric short time, data communication passes through crystal connector RJ45_1-relay relay 1- network
Transformer transformer 1- analog switch Analog Switch 1-analog switch Analog Switch 2- network transformation
Device transformer 2- relay relay 2-RJ45_2 crystal connector completes forwarding.At this stage, CPU_Ctrl_
SWITCH1, CPU_Ctrl_SWITCH2 and CPU_Ctrl_RELAY are " 0 " (low level), i.e. network transformer
Transformer 1 passes through analog switch Analog Switch 1 and analog switch Analog Switch 2 and network transformer
Transformer 2 is connected, but since the switch speed of relay relay is slower, speed is in ms rank, so in lower electricity
It in short time, cannot complete to switch at once, i.e., RJ45_1 crystal connector can't pass through relay relay 1 and relay
Relay 2 is connected with RJ45_2 crystal connector；At this point, analog switch Analog Switch 1 and analog switch Analog
Switch 2 has completed to switch in the case where VCC_BAR has electricity, and the time is ns rank, i.e. network transformer
Transformer 1 passes through analog switch Analog Switch 1 and analog switch Analog Switch 2 and network transformer
Transformer 2 is connected；In order to maintain VCC_BAR to maintain electricity, need to add diode D1 and capacitor C1, capacitor plays storage
The effect of energy continues to analog switch Analog Switch work a period of time, relay relay is waited to cut after a power failure
It changes completion (relay relay 1 is connected with relay relay 2), the effect of diode is to guarantee capacitor only to analog switch
Analog Switch power supply, does not power to other IC, reduces capacitor discharge load, makes after lower electricity, analog switch Analog
Switch can be worked longer, and greater than the switching deadline of relay, realized 0 time difference switching of route, guaranteed communication number
According to smoothness.
After completing switching (relay relay 1 is connected with relay relay 2) to relay, data pass through at this time
RJ45_1 crystal connector-relay relay 1- relay relay 2-RJ45_2 crystal connector completes forwarding, reaches lower electricity
Afterwards, guarantee that communication is normal, realize bypass function.
Isolating transformer and relay can play the role of Network Isolation, guarantee the electrical isolation of front and back end, enhancing letter
Number anti-interference ability, play the role of security protection, improve system stability.
Finally, it should be noted that above-described embodiments are merely to illustrate the technical scheme, rather than to it
Limitation；Although the present invention is described in detail referring to the foregoing embodiments, those skilled in the art should understand that:
It can still modify to technical solution documented by previous embodiment, or to part of or all technical features into
Row equivalent replacement；And these modifications or substitutions, it does not separate the essence of the corresponding technical solution various embodiments of the present invention technical side
The range of case.
