Description
Technical field
The utility model is related to power system conversion equipment, specially a kind of transformer station's multi-function printer converting means
Put.
Background technology
At present, intelligent substation protection screen does not configure printer, due to each producer's protective relaying device printing interface, beat
Print data wire disunity, and intelligent substation network printing technology and immature, the data-printing of protection device relies primarily on biography
It is unified to be printed to one, therefore the protective relaying device of each producer must use each special printer and print wire, from
And cause to print the work such as definite value and fault oscillograph in transformer station and become cumbersome, have a strong impact on operating efficiency.
The content of the invention
The utility model is in order to solve existing transformer station's printer and print data line is not general causes each producer protection dress
Putting must have the influence operating efficiency that wastes time and energy using special printer and print wire, there is provided a kind of transformer station
Multi-function printer conversion equipment.
The utility model adopts the following technical scheme that realization：Transformer station's multi-function printer conversion equipment, including connect
Mouth converter, printer parallel port, device serial port, device printing external interface；One end of interface convertor is serial with device
Mouth, device printing external interface connection, the other end of interface convertor are connected with printer parallel port.
After printer start, printer standard is sent to each protective relaying device by interface convertor from printer parallel port
The signal got ready, protective relaying device sends print data after interface convertor is changed to printer parallel port, overcomes
Existing substation data printing there is a problem of wasting time and energy and influences operating efficiency.
Interface convertor inside includes TD lines, RD lines, GND lines, DTR lines, and the TD lines in interface convertor are serial with device
TD, TXD line connection of mouth pin sequence number 3, device printing external interface, and TD lines and printer parallel port in interface convertor
Pin sequence number 3 connect；RD lines in interface convertor are connected with the RD lines of device printing external interface, and interface convertor
RD lines are connected with the pin sequence number 2 of printer parallel port；GND lines and device serial port pin sequence number 5, dress in interface convertor
Put GND, SGND line connection of printing external interface, and GND lines and the pin sequence number 7 of printer parallel port in interface convertor
Connection；The pin sequence number 8 of DTR lines and device serial port in interface convertor, pin sequence number 6, device print external interface
RTS lines are connected, and DTR lines in interface convertor are connected with the pin sequence number 20 of printer parallel port.
The utility model reasonable in design reliability, can be entered using a printer to the protective relaying device of each producer
Row printing, facilitates the printing of relay protection personnel, improves operating efficiency, investment of substations cost is reduced, with making
With convenient, simple structure and practical advantage.
