Technical field
The utility model relates to a kind of automatic switching control equipment, particularly a kind of data network link monitoring automatic switching control equipment.
Background technology
Transformer station's two routers of data dispatching net configuration are as pe router, by GE interface inter-link, standby each other between two routers.The business realizing vlan subregion that two routers connect, realizes VRRP to safe I district and backs up mutually, and respectively by special-purpose 2M line access dispatching data backbone network, and the interface by a switch is connected to safe I district business respectively.On two switches, all realize vlan subregion, between switch, by link-aggregation, realize trunking.According to the corresponding safe class of business in station, the corresponding vlan interface of access switch.
According to safe class, the safe I district in the docking station of transformer station's data dispatching net controlled area, the business in safe I district comprises remote terminal unit (RTU), AVC substation, five-preventing system, phasor measuring set (PMU) etc.At the special-purpose longitudinally encrypting and authenticating device of two electric power of safe I district deploy, be plugged between router and switch.Two encrypting and authenticating devices are active and standby relation.Consider the authentication of arriving at a station between end and two systems of dispatching terminal, longitudinal communication process in safe I district adopts between longitudinal encrypting and authenticating device and authenticates and realize.
When normal, the vrrp interface priority of active router is higher than standby router corresponding interface, and safe I district business datum is by after main encryption devices encrypt, and through router forwarding data, standby encryption device and standby router are in stand-by state.When active router fault, standby router monitors active router interface fault by vrrp vrid track interface, the vrrp interface priority of active router is reduced, make the vrrp interface priority of standby router higher than active router, data link switches on standby router and standby encryption device, switches to standby link while realizing primary link failure.But actual motion is found, when main encryption plant failure or active router interface are when seemingly-dead, primary data link is interrupted, but active router vrrp interface is at UP state, standby router is still in stand-by state, can not start link and automatically switch, while can only the personnel of Shi main website finding link failure, carry out that link is manual to be switched.In this case, can not realize link failure finds in time.Before manual switching, the business datum communicating interrupt in safe I district.
Summary of the invention
The purpose of this utility model is to provide a kind of switching reliable according to the deficiencies in the prior art part, without the data network link monitoring automatic switching control equipment that interrupts data communication.
The purpose of this utility model realizes by following approach:
Data network link monitoring automatic switching control equipment, its structural feature is, includes the signal gathering unit, data processing unit and the handover trigger unit that sequentially connect; Wherein signal gathering unit connects respectively the data-interface of active router, standby router, main encryption authenticate device and standby encrypting and authenticating device, and the output control terminal of handover trigger unit connects respectively active router and standby router.
Signal gathering unit connects respectively active router, standby router, the data-interface of main encryption authenticate device and standby encrypting and authenticating device is in order to gather the data-interface state of active router and standby router, and the Data Packet Encryption number of times of main encryption authenticate device or standby encrypting and authenticating device, data processing unit is processed and judges above-mentioned data respectively, if the data-interface of active router is seemingly-dead, or the Data Packet Encryption number of times of encrypting and authenticating device does not increase, judge that primary data link is in malfunction, now extract the data-interface state of standby router, if its Interface status un-activation, still when stand-by state, send switching command to handover trigger unit, handover trigger unit activating is for router, carry out the automatic switchover of data link.Like this, just can guarantee the reliability that data link is switched, avoid magnifying because not switching in time the fault causing, guarantee the reliable and stable operation of data link.
The utility model can further be specially:
Also include signal Alarm Unit, it is connected with data processing unit.
In order to realize the timely discovery to data link failure, when data processing unit judges primary data link in malfunction, triggering signal Alarm Unit sends alarm signal simultaneously, notifies attendant to process in time, guarantees data link reliability of operation.
Described signal gathering unit is communication interface modules, and data processing unit is programmable processor.
Communication interface modules is as RS485 interface module etc., and programmable processor is the data processors such as computer or single-chip microcomputer, can some data of data handling procedure be set and be processed.
In sum, the utility model provides a kind of data network link monitoring automatic switching control equipment, by the data of data link are carried out to monitoring analysis, when primary data link breaks down, and owing to being that the interface of main encryption plant failure or active router is seemingly-dead, cause standby link not start while switching.By data network link monitoring automatic switching control equipment, send switching command, realize the automatic switchover to data link, send the alarm signal of primary link failure simultaneously.This device is arranged on encryption Intranet, does not change legacy data web frame, and occupied bandwidth is little, does not affect original data communication, and test bandwidth redundancy reaches requirement.Can guarantee reliability and stable operation that data link is switched.
Accompanying drawing explanation
Figure 1 shows that the structural representation of data network link monitoring automatic switching control equipment described in the utility model in data link.
Figure 2 shows that the principle framework schematic diagram of data network link monitoring automatic switching control equipment.
Below in conjunction with embodiment, the utility model is described further.
Embodiment
Most preferred embodiment:
With reference to accompanying drawing 1, the version of data link first, transformer station's two routers of data dispatching net configuration are as pe router, be respectively active router and standby router, by GE interface inter-link, standby each other between the two, and respectively by special-purpose 2M line access dispatching data backbone network.The two also disposes respectively an encrypting and authenticating device, correspond to respectively main encryption authenticate device and standby encrypting and authenticating device, two encrypting and authenticating devices are connected to safe I district business by the interface (being respectively safe I district's interface of switch 1 and the safe I district interface of switch 2) of a switch respectively.The data link at active router place is primary data link, and the data link at standby router place is standby data link.
Data network link monitoring automatic switching control equipment described in the utility model, includes signal gathering unit, data processing unit, the handover trigger unit sequentially connecting and the signal Alarm Unit being connected with data processing unit; Wherein signal gathering unit connects respectively the data-interface of active router, standby router, main encryption authenticate device and standby encrypting and authenticating device, and the output control terminal of handover trigger unit connects respectively active router and standby router.Described signal gathering unit is communication interface modules, and data processing unit is programmable processor.
