Abstract
The invention relates to a double-set CDT (Cycle Distance Transmission) protocol-based two-way communication method in an intelligent substation. The method comprises the following steps of: (1) respectively installing CDT protocols on an integrated platform host computer and a remote viewing host computer; (2) performing serial port arrangement on the integrated platform host computer and the remote viewing host computer; (3) connecting an intelligent receiving port of the integrated platform host computer with a remote viewing sending port of the remote viewing host computer through a twisted pair, and connecting an intelligent sending port of the integrated platform host computer with a remote viewing receiving port of the remote viewing host computer through the twisted pair; (4) setting parity check bits of the integrated platform host computer and the remote viewing host computer as being null and setting baud rate as 1200bps; and (5) connecting the remote viewing host computer with a remote viewing camera. The method provided by the invention is simple and is easily used. According to the method, the two-way communication of the integrated platform host computer and the remote viewing host computer in the intelligent substation is efficiently performed, a real-time image of a remote viewing system is sent to an integrated platform and is monitored, and the remote viewing camera is correctly rotated to a shifting switch.
Description
Technical field
The invention belongs to the intelligent substation field, in especially a kind of intelligent substation based on the two-way communications of two cover CDT stipulations.
Background technology
At present, electrical network develops toward the intelligent grid direction, requires electrical network to possess informationization, automation, interactive, and corresponding transformer station also should develop into intelligent substation.Intelligent substation is to combine the further lifting on transformer station and digital transformer substation basis in tradition.From combining from transformer station to digital transformer substation, arrive intelligent substation again, the effect of network service in transformer station strengthens day by day.The IEC61850 standard is introduced in the network service between primary equipment and the secondary device; Caused the great variety of electric substation automation system; Comprise unified platform main frame, remote viewing main frame and remote viewing camera in the intelligent substation, in intelligent substation, be provided with switch cubicle, each switch cubicle is provided with a killer switch; The variable condition of each killer switch needs the monitoring of remote viewing camera; When especially circuit breaker switch state changed, the interlock function of remote viewing camera in the time of can't realizing the killer switch displacement at present promptly can't realize the two-way communication of unified platform main frame and remote viewing main frame in the intelligent substation.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art; Two-way communication based on two cover CDT stipulations is provided in a kind of intelligent substation; This method is simple and easy to the two-way communication that can effectively carry out unified platform main frame and remote viewing main frame in the intelligent substation, thereby the remote viewing camera is linked.
The present invention solves its technical problem and realizes through following technical scheme:
Based on the two-way communication of two cover CDT stipulations, the step of its method is in a kind of intelligent substation:
(1), on unified platform main frame and remote viewing main frame, the CDT stipulations is installed respectively;
(2), unified platform main frame and remote viewing main frame are carried out serial port setting;
(3), the intelligent receiving port of unified platform main frame is connected the remote viewing transmit port of remote viewing main frame through twisted-pair feeder, the intelligent transmit port of unified platform main frame is connected the remote viewing receiving port of remote viewing main frame through twisted-pair feeder;
(4), the parity check bit of unified platform main frame and remote viewing main frame is set to not have, baud rate is set to 1200bps;
(5), the remote viewing main frame is connected with camera.
Advantage of the present invention and beneficial effect are:
1, realized intelligent substation unified platform The Application of Technology based on the two-way communication of two cover CDT stipulations in this intelligent substation; Should realize the interlock function of remote viewing camera when having realized the circuit breaker switch changed position; Realize the bidirectional data transfers between two main frames smoothly, realized the effect of two-way communication.
2, the inventive method is simple and easy to use; Can effectively carry out the two-way communication of unified platform main frame and remote viewing main frame in the intelligent substation; Thereby the remote viewing camera is linked, and is based on the two-way communication of two cover CDT stipulations in a kind of safe and reliable intelligent substation.

Embodiment
Through specific embodiment the present invention is made further detailed description below, following examples are descriptive, are not determinate, can not limit protection scope of the present invention with this.
Based on the two-way communication of two cover CDT stipulations, the step of its method is in a kind of intelligent substation:
(1), on unified platform main frame 1 and remote viewing main frame 5, the CDT stipulations is installed respectively;
(2), unified platform main frame and remote viewing main frame are carried out serial port setting, be provided with on the unified platform main frame serial ports 2 as receiving port, serial ports 3 as transmit port; With serial ports 7 on the remote viewing main frame as receiving port, serial ports 6 as transmit port;
(3), the intelligent receiving port of unified platform main frame is connected the remote viewing transmit port of remote viewing main frames through twisted-pair feeder 4, the intelligent transmit port of unified platform main frame is connected the remote viewing receiving port of remote viewing main frame through twisted-pair feeder;
(4), the parity check bit of unified platform main frame and remote viewing main frame is set to not have, baud rate is set to 1200bps;
(5), the remote viewing main frame is connected with remote viewing camera 8.
Described CDT stipulations are circulation telemechanical stipulations.
Two computers main frame of the present invention is respectively unified platform main frame in the transformer station, and the remote viewing main frame in the transformer station, routine; Two host computer using one cover CDT stipulations transmission data; The CDT stipulations are the one-way transmission stipulations, and unified platform only need be accepted the image that sends over from the remote viewing main frame as information terminal; Promptly only as the main frame of CDT stipulations, and the remote viewing main frame is as the slave of CDT stipulations.But the unified platform project demand is realized Premium Features, the function that promptly " should realize the interlock of remote viewing camera during the killer switch displacement ".This just requires when certain switch changed position, and unified platform sends a displacement infomational message should for the remote viewing main frame.This method has realized, with the slave of unified platform main frame as the CDT stipulations, and the remote viewing main frame has been solved the two-way communication problem as receiving main frame, should realize the interlock of remote viewing camera when having realized the circuit breaker switch changed position.
Claims (1)
- In the intelligent substation based on the two-way communications of two cover CDT stipulations, it is characterized in that: steps of the method are:(1), on unified platform main frame and remote viewing main frame, opens the CDT stipulations respectively;(2), unified platform main frame and remote viewing main frame are carried out serial port setting;(3), the intelligent receiving port of unified platform main frame is connected the remote viewing transmit port of remote viewing main frame through twisted-pair feeder, the intelligent transmit port of unified platform main frame is connected the remote viewing receiving port of remote viewing main frame through twisted-pair feeder;(4), the parity check bit of unified platform main frame and remote viewing main frame is set to not have, baud rate is set to 1200bps;(5), the remote viewing main frame is connected with the remote viewing camera.
