Send relief area BD, when CPU inquires reception buffering BD non-NULL, CPU be responsible for reading and walk appointed buffer data and by BD non-NULL
Identify clear 0；If it is full up to receive buffering, no longer receive other message until CPU will receive the non-NULL mark clear 0 of buffering BD；
When CPU needs to send message, it is necessary first to inquiry transmission buffering BD takies mark, is designated 1 if taken,
Then this transmission buffer data does not the most send and terminates, and CPU must not write data toward this relief area；
If having taken and being designated 0, then this transmission relief area does not has data to be sent, and CPU can write data toward this relief area, writes
Put 1 by CPU data are sent taking mark by FPGA after complete.
(3) configuration file being carried out type expansion, in configuration message type, first distribute access port, next defines light
Type IEC61850-9-2 of Ethernet interface and IEC60044-8256 point sampling rate, IEC61850-9-2 and IEC60044-880
Point sampling rate, channel type and the number of last opposed inlet configure, the type of configuration, number and electronic mutual inductor shape
State is consistent, to ensure that digital combining unit processes the accuracy of outgoing message after data.
In described step (1), each mouth carries out zoning by function and is divided into cascade district, 256 SV memory blocks, and FT3 deposits
Storage area, synchronizes time zone.
In described step (2), described certain time is 0.5ms.
Combining unit device support simultaneously IEC61850-9-2 and IEC60044-880 point harvester sample rate,
The input of IEC61850-9-2 and IEC60044-8256 point harvester sample rate message, supports output IEC61850-9-2 simultaneously
With IEC60044-880 point sampling value message and IEC61850-9-2256 point IEC61850-9-2 sampling value message.
Compatibility on combining unit device harvester input interface hardware, it is only necessary to change optical module the most changeable different types of
Harvester inputs.
Compared with prior art, the present invention is reached to provide the benefit that:
The functions such as the present invention has digital output, digital output, voltage switching, and clock synchronizes, voltage switching, can be convenient
Access various with IEC61850-9-2 stipulations or IEC60044-8 stipulations the electronic mutual inductor as source, there is the strongest compatibility
Property, solve current digital combining unit " one to one " customization the strongest compatible problem.
Accompanying drawing explanation
Fig. 1 is the systematic schematic diagram of the present invention.
Fig. 2 is the flow chart of the present invention.
Detailed description of the invention
Following example are only used for clearly illustrating technical scheme, and can not limit the present invention with this
Protection domain.

Time zone etc..
2. the data interaction of FPGA Yu CPU no longer uses interrupt mode, and changes CPU inquiry mode into.CPU is every 0.5ms
The reception of inquiry FPGA and transmission relief area BD.When CPU inquires reception buffering BD non-NULL, CPU it is responsible for reading and walks to specify slow
Rush district's data and BD non-NULL is identified clear 0, if it is full up to receive buffering, no longer receiving other message until reception is buffered by CPU
The non-NULL mark clear 0 of BD.When CPU need send message time firstly the need of inquiry send buffering BD take mark, if
Taking and be designated this transmission buffer data of 1 explanation and the most do not send and terminate, CPU must not write data, if toward this relief area
Taking and be designated this transmission relief area of 0 explanation and do not have data to be sent, CPU can write data in this relief area in the past, after writing by
CPU puts 1 data sent taking mark by FPGA.
3. pair configuration file carries out type expansion, in configuration message type, first distributes access port, secondly definition light with
The too type 9-2LE(SV electronic mutual inductor of network interface), 9-2(SV cascade), FT3(FT3 electronic mutual inductor), finally to access
Channel type and the number of mouth configure, and type and number must be digital to ensure with electronic mutual inductor state consistency
The accuracy of outgoing message after combining unit process data.
A kind of compatible to IEC 61850-9-2 harvester stipulations of the present embodiment and the numeral of IEC60044-8 harvester stipulations
The functions such as combining unit has digital output, digital output, voltage switching, and clock synchronizes, voltage switching, can connect easily
Enter various with IEC61850-9-2 stipulations or IEC60044-8 stipulations the electronic mutual inductor as source, there is the strongest compatibility
Property.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For Yuan, on the premise of without departing from the technology of the present invention principle, it is also possible to make some improvement and deformation, these improve and deformation
Also should be regarded as protection scope of the present invention.
