Background technique
In the industry spot with ethernet communication device transmission signal, Ethernet power port bypass (redundant link) skill
Art has been applied very extensive, such as: compartment data monitoring, road monitoring etc..Traditional Ethernet power port bypass
The implementation method of technology is the switch opened and closed using power supply as bypass function, is closed when equipment normal power supply
Bypass function, bypass function then automatically turns on when the device is powered off, so that transmission signal can be straight from power cutoff device
The transparent transmission past is connect without making entire interrupted communication link, but certain functions of bypass in special circumstances can not come into force, and such as set
It is standby power on after start to start, the system inside equipment needs a period of time, in the process from that time is powered on to start completion
Equipment does not enter normal mode of operation also, but because equipment has been in power supply state, bypass function is equally also closed
It closes, entire communication link just interrupts at this time.For another example, some circuit unit in equipment normal course of operation in equipment
It breaks down suddenly, causes equipment to be unable to normal transmission signal, but equipment, also in power supply state, bypass function can not give birth to
Effect, also results in entire interrupted communication link.
Summary of the invention
The embodiment of the present invention is designed to provide a kind of circuit for realizing Ethernet power port redundant link, can be in system
When breaking down in start-up course or operational process, Ethernet power port redundant link function is provided, guarantees that equipment operates normally.

It connects device to be directly connected to, not influenced by failure switched circuit, guarantee the unimpeded of entire ethernet link.
Detailed description of the invention
Fig. 1 is the schematic block circuit diagram that the present invention realizes Ethernet power port redundant link.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Specific implementation of the invention is described in detail below in conjunction with specific embodiment:
As shown in Figure 1, a kind of circuit for realizing Ethernet power port redundant link, comprising:
Cpu control circuit, power circuit, switched circuit, power port Bypass circuit and two Ethernet power port connectors
(Ethernet power port connector 1 and Ethernet power port connector 2)；Power circuit respectively with cpu control circuit, switched circuit and electricity
Mouth Bypass circuit connection；Cpu control circuit respectively with switched circuit and power port Bypass circuit connection；One Ethernet power port
Connector is connected by a port (Port1 in figure) of power port Bypass circuit and switched circuit；Another Ethernet power port
Connector is connected by another port (Port2 in figure) of power port Bypass circuit and switched circuit；
The operating status of cpu control circuit monitoring switched circuit；
When switched circuit is in normal operating conditions, cpu control circuit gives power port Bypass circuit control signal, closes
Power port Bypass circuit, so that an Ethernet power port connector passes sequentially through power port Bypass circuit, one of switched circuit
Port, switched circuit, switched circuit another port connect with another Ethernet power port connector；
It does not work or when malfunction, cpu control circuit gives power port Bypass circuit control signal when switched circuit is in,
Enable power port Bypass circuit so that Ethernet power port connector by power port Bypass circuit directly with another ether
The connection of net power port connector.
The present invention increases cpu control circuit on the basis of traditional power port bypass system, is monitored by cpu control circuit
Running situation is enabled and is closed to control bypass circuit.When power circuit powers on, when switched circuit needs one section
Between starting could work normally, within this period cpu control circuit by control signal enable bypass circuit, ether
Net power port connector 1 and the direct connection of Ethernet power port connector 2, interrupt entire communication link not；When switched circuit is normal
After operation, cpu control circuit is further through control signal-off bypass circuit, Ethernet power port connector 1 and Ethernet electricity
Mouth connector 2 continues link communication by switched circuit connection.
In addition, cpu control circuit can monitor the operating condition of switched circuit, work as monitoring after switched circuit operates normally
To switched circuit it is faulty can not normal transmission signal when, cpu control circuit can pass through control signal enable bypass circuit, protect
The unimpeded of communication link is held, after switched circuit trouble shooting, cpu control circuit is further through control signal-off bypass electricity
Road continues link communication.
The present invention solves in special circumstances power port bypass function of the equipment in system starting process and the system failure
The problem of cannot coming into force and leading to interrupted communication link, reducing equipment can not work normally the loss caused by industry spot.
The embodiment of the present invention monitors the working condition of switched circuit by the cpu control circuit moment, so that power port Bypass
Circuit is enabled or is closed in real time, and switched circuit has been effectively ensured in failure or off position, and two Ethernet power ports connect
It connects device to be directly connected to, not influenced by failure switched circuit, guarantee the unimpeded of entire ethernet link.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to restrict the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
