Specific implementation mode
Embodiments of the present invention are described below in detail, the example of embodiment is shown in the accompanying drawings, wherein identical or class
As label indicate same or similar element or element with the same or similar functions from beginning to end.Below with reference to attached
The embodiment of figure description is exemplary, and can only be used to explain embodiments of the present invention, and should not be understood as to the present invention
Embodiment limitation.
As shown in Figure 1, being all independent from each other before being connected to 2M interface communication adapting appts per pole pole control system.
Each pole is required for two channels, respectively as main channel and alternate channel.In order to ensure two pole telecontrol system it is reliable
Property, the main channel of a pole and the alternate channel of another pole can generally be walked with optical fiber all the way.In this way when certain optical fiber event all the way
When barrier, only there are one the main channels of pole to be affected.
Polar control system is made of the dual system of redundancy, and switch logic ensures that each moment is only there are one healthier
System is in duty system.When with being communicated to station, the on duty and back-up system of each pole can be received to the on duty of same pole that stand
The data that system is sent；On the other hand, two systems are all sending out data outward, and it is logical that the data that they send out are sent to PCS-9518
Road switching device, on the apparatus by the signal on duty of system, i.e. " Active " signal is selected.After selection, only
There are the data of duty system that can just be sent to station.
Communication refers to a certain time (or pole 2) pole control system of pole 1 of common-tower double-return current conversion station and the opposite end change of current between pole control system station
The communication stood between the control system of 1 pole of same time pole (or pole 2), or conventional 1 (or pole 2) pole control system of current conversion station pole and opposite end current conversion station
Communication between the control system of 1 pole of same time pole (or pole 2).That is the communication of the same direct current pole pole control system in current conversion station both ends.
The communication of pole control system interpolar refers to logical between a certain time 1 pole control system of pole of common-tower double-return current conversion station and 2 pole of pole control system
Communication between news, or conventional a certain time 1 pole control system of pole of current conversion station and 2 pole of pole control system.
In the prior art, communication controls A operations on duty in pole between pole control station, and pole controls B system and catastrophe failure, emergency occurs
Situations such as switch to during trystate overhauled, Communication Card causes pole to be controlled extremely between the station of control A system hosts in pole on duty
Complete failure is communicated between standing.The present invention will propose new current conversion station pole control system interpolar according to this, stand between communication redundant apparatus and
Pole control system interpolar, stand between the means of communication.
Embodiment 1
The present invention proposes a kind of current conversion station pole control system interpolar, stand between communicate redundant apparatus, be applied to high direct voltage or
Extra-high voltage Control protection system, the current conversion station pole control system interpolar, stand between communication redundant apparatus include duty system and spare system
System two parts, each pole include main channel and alternate channel, and duty system includes the first Communication Card on duty, and back-up system includes
First spare Communication Card, duty system also include the second Communication Card on duty.
Specifically, the first Communication Card on duty and the second Communication Card on duty all include the first communication port and the second communication
Mouthful, it is communicated between pole control system station and first passage completion is used as by the first communication port of the first Communication Card on duty and by second
First communication port of Communication Card on duty is completed as second channel, the first Communication Card on duty and second communication board on duty
Second communication port of card is arranged to the alternate channel communicated between station.
Specifically, the first Communication Card on duty and second Communication Card on duty all include third communication port and four-way
Interrogate mouth, the communication of pole control system interpolar by the third communication port of the first Communication Card on duty is used as first passage completion and by the

As shown in Fig. 2, communicating the 1st and No. 2 mouth by controlling Communication Card NR1127A in host positioned at pole between pole control system station
It is completed as two channels communicated between pole control system station.The communication of pole control system interpolar is by being located at Communication Card in pole control host
The the 3rd and No. 4 mouth of NR1127A is completed as two channels that pole control system interpolar communicates.Wherein, PCS9518 indicates channel switching
Device, MUX-2MM indicate that interface arrangement, NR0212 indicate interior communication interface unit.
Since general fiber optic communications devices fault distinguishing principle is to sentence receipts not sentencing hair, when present apparatus receiving terminal RX can not receive pair
When the optical signal that side transmitting terminal TX is sent, the present apparatus can send out alarm signal, and when present apparatus transmitting terminal TX cannot normally be sent out,
And receiving terminal RX, when can be normally received the light that offside is sent, the present apparatus does not send out alarm signal.Communications equipment room goes back to two direct current stations
Between in communication interface cabinet B MUX-2MM interface arrangements B corresponding interior communication interface lists in channel between going back to two direct current pole, 1 pole control station
Optical port FLOS alerts red light and is always in first NR0212, and power port ELOS warning lights are not bright, and operation RUN run indicator is extinguished.Accordingly
It can determine whether the pole control B cabinet communication port switch units of MUX-2MM interface arrangements in fiber direct connection communications equipment room communication interface cabinet B
NR0211 failures lead to 1 pole control system A/B host interior communication channel B failures of direct current pole.
Redundancy dual system is controlled when with being communicated to station in pole, and pole control value class and back-up system can receive the value to same pole of standing
The data that class's system is sent；On the other hand, control redundancy dual system in our station pole is all sending out data outward, and the data that they send out are sent
To PCS-9518 channel switching devices by selection after, only the data of duty system can just be sent to station.Pole communicates between control station
Experiment shape is switched in situations such as pole control system host A operation on duty, pole control system host B generation catastrophe failure, emergency
During state is overhauled, there are once any exception can cause Communication Card NR1127A between the station that A system hosts are controlled in pole on duty
Pole communicates complete failure between control station, so can rectification side and inverter side jointly control, both sides unblock the hidden danger of coordinated manipulation etc.,
I.e. completely redundant design is not implemented in order circuit between pole control system station.
To solve the problems, such as this, B10 slots position increases Communication Card NR1127A between station on two station pole control system A/B hosts
As the redundancy board communicated between the control station of pole.As shown in figure 3, communication controls first, host by being located at pole between pole control system station
