When hot stand-by duty.Primary channel is all made of 104 network communication modes after SCADA system construction, and the telemechanical of electric substation
Master control then uses dual master control mode.
In today of power automation high speed development, SCADA system has become the core of power automation construction, in fact
Shi Xing, accuracy, stability and continuity are the emphasis of automatically working, therefore we need to spend a large amount of resource to it
It is safeguarded.The guarantee that SCADA system operates normally is exactly the unimpeded of data channel, this is also automated maintenance person works
Emphasis and difficult point, it is wide that the professional knowledge being related to is crossed in channel maintenance work, and work region span is big, the spies such as problem crypticity height
Point, needing each department to cooperate just can make grid operation data accurately be sent to SCADA system.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of SCADA dispatching system data acquisition primary channel is online
Compare device and method, realize on-line monitoring SCADA system primary channel quality, and online compare primary channel receive it is distant
Survey, remote signalling data can in time alert the problem on channel to judge channel and telecontrol device operation conditions, be
SCADA system normal operation provides safeguard.
In order to solve the above technical problems, the present invention adopts the following technical scheme: SCADA dispatching system data acquisition is active and standby logical
Road compares device online, comprising:
The active and standby interchanger of data network, by all-network channel mirror image to a specific network mouth, so that channel data is adopted
Acquisition means can collect the data message in all channels；
Primary channel compares device, and the data message that channel data acquisition device acquires is compared one by one；
Channel compares terminal, and primary channel comparing result compares terminal in channel and shows.
Optionally, the data message includes telemetering, remote signalling, alarm signal.
The present invention also provides a kind of online control methods of SCADA dispatching system data acquisition primary channel, including it is as follows
Step:
Step S1 obtains primary channel information in the same period of setting in such a way that Network Mirror mouth is monitored；
Step S2 carries out protocol analysis to the primary channel information of acquisition in real time, formed about primary channel event simultaneously
The event of the primary channel is saved in the database；
Step S3 carries out automatic comparison to the event of the primary channel, generates comparison result；
Step S4 triggers generation alarm event if comparison result is abnormal, saves alarm event in the database, and real
When display alarm event.
The present invention by adopting the above technical scheme, has the following technical effect that
1, channel comparison device receives backbone exchanging network data, and backstage is passed to after safety insulating device and carries out message solution
Analysis and comparison, real-time judge primary channel operating condition find channel failure in time.
2, customized, deep monitoring.The standard of channel quality, monitoring are formulated for the characteristics of channel maintenance management work
In the consistency of line passage and the transmitted data of alternate channel, it is ensured that the telemetering of primary channel transmission, remote signalling data are accurate
It is errorless.
3, the more protocol synthesis monitorings of multichannel.Suitable for SCADA dispatching system use it is each simulation, number, network channel,
The specification of CDT, 101,104, facilitate automatic operating maintenance personnel and communicate maintenance personnel work, improve data real-time and
Stability.
The specific technical solution of the present invention and its advantages will in the following detailed description in conjunction with attached drawing into
Row detailed description.
Detailed description of the invention
Present invention will be further described below with reference to the accompanying drawings and specific embodiments:
Fig. 1 is that SCADA dispatching system data acquisition primary channel of the present invention compares apparatus structure schematic diagram online.
Specific embodiment
The present invention mainly applies switch port mirror image technology.
Port Mirroring function is by the way that in switch or router, the data traffic of one or more source ports is forwarded to
Some designated port realizes the monitoring to network, and designated port is referred to as " mirror port " or " destination port ", not tight
Ghost image sound source port is normally handled up in the case where flow, and analysis can be monitored by flow of the mirror port to network.?
Image feature is used in enterprise, management can be monitored to the network data of enterprises well, when network is out of order
It waits, failure can be quickly located.
The effect of switch port mirror image is primarily to provide message information to primary channel comparison device.It both can be with
Realize that several source ports can also be monitored to a monitoring port mirror image data from several VLAN to one in a VLAN
Port Mirroring data.Shown in figure network topological diagram as above, what is circulated on the all-network channel of the active and standby interchanger of data network is all
Data flow is mirrored to some specified monitoring port of the active and standby interchanger of data network, and primary channel comparison device passes through monitoring
Port has received all data flows to circulate on all all-network channels from the active and standby interchanger of data network.In Port Mirroring
During task, user can be by state modulator, to indicate data flow type that needs monitor；It can also will be one or more
End, mouth, one or more VLAN are spread as source port, and by the one-way or bi-directional data sent or received from these ports
Send to monitoring port, but no matter which kind of situation, in a port mirror image task, the monitored direction of all source ports is all necessary
It is consistent.Port Mirroring task will not influence the normal work of interchanger.After a port mirror image task is established, according to
Different state or operation locating for interchanger, task can be logged into day in activation or unactivated state, simultaneity factor
Will.By " show monitor session " order can display port mirror image current state.
Embodiment one
