 Sphere of application： |
| Power Grid Dispatching system of region, county, and the communication dispatching of large factory, transformer substation, power plant, LAN. |
| Main characteristic: |
(1) Design catering for the demand of large region dispatching flexible configuration，fully satisfied with the demands of larger, midst and small system, fit for the data collecting, analysis and control of factory monitor centre, strong function, low cost.
(2)Open structure with multi stages is convenient to connect with all kinds of RTU communication protocol internal and aboard. Double server front system, reliable running, double inter-exchange 100M net, safety and fast data transmission.
(3) Perfect connecting project, reliable protection: disconnector and firewall，which stop all direct exchange of data request and real-time data server. Support X.25 grouping exchange, WWW data browse, realize Internet free visit and connect with MIS or EMS system exchanging real-time data.
(4) Friendly interface, convenient operation, be able to output all kinds of report, curve, and chart, and easy to inquire device information. Flexible display way, provides multi-display, projection and LED hall show.
(5) Closely surround the newest demand of power system to design, mature system, strong pertinence, stable and reliable running, owning the experience of tens of operation in the field. |

| Introduction of main soft of system ： |
(1) Prefixed system:
It can deal with the transform data information, which the highest is 9600bps, 256 channels. It's basic on the CDT protocol, has abundant protocol library, can connect with several RTU home and abroad and use custom protocol. It owns the function of configuring on-line and modifying parameter, the function of double computer and double channels, provides several remote monitor and maintenance ways; transmits data by several channels, separates with backstage and uses TCP/IP agreement 100M to transmit data.
(2) System Main-control soft:
It can deal with all collecting, showing them with picture, form and text, collect all demand information, give a light and voice alarm, voice prompt, whe n the telecontrol is unusual or the switch is moved, and record them. It has the function of SOE return, control by telecontrol, remote regulating and Adjust-Time, modify and print all collecting and computational complexity on-line.
(3) Project soft:
It can edit all basic pixel and picture arbitrary in size( such as wiring diagram, device working status displaying，curve, bar graph), pass implication picture information directly to set and record data, have the picture to realize moving tidal current, provide several ways for picture transfer, show the picture automatically when events happen, utilize mouse to handle the information of telemetry, remote surveillance, running status and tap. All operation comes with detail prompt.
(4) Database
Commercial data SQL separate with real-time data and organic combine at the same time, which ensures the utility and standardization of data, provides a friend interface of building data ware house and recording data, which can set data warehouse according to the user demand. It can build and modify data content on-line, no effect of real-time running of system, support remote copy of data. After modify the data, each computer can transmi t them to others.
(5) WWW scan soft:
It supports X.25 Protocol's remote grouping exchange-net communication，realize net connect with remote computer and scan between nets using Internet. It adopts different net communication agreement according to user's specific demands, exchange information by net bridge and management net, show the real-time data system picture, form and running record on other side of the management net computer. |
