Power Distribution Automation System Solution
I. Introduction
Power distribution automation refers to the remote monitoring of the operating status of the entire power system. Thanks to the remote monitoring method, real-time performance and controllability are greatly enhanced, and the workload is greatly reduced.
II. Current situation
However, the traditional power distribution automation system uses RS485/422 network to transmit data to computer terminals. The theoretical transmission distance of RS485/422 network is 1200M, and it is often affected by factors such as cables and construction. Transmission distance is greatly reduced
Traditional power distribution automation system, as shown below:
III. Power Distribution Automation Based on TCP/IP Network
In order to enable the monitor to monitor anytime, anywhere, the best solution is to monitor through the TCP/IP network. Because the monitoring based on TCP/IP network is not limited by the transmission distance.
Power distribution automation based on TCP/IP network, as shown below:

Five East Digital Product C2000 Performance Features
1. Features:
The C2000 can realize the function of directly converting serial port data transmission to TCP/IP data transmission. The data collected by the collection device from the serial port can be easily packaged on the network, and then quickly and steadily transmitted to the console terminal through the TCP/IP network. The transmission performance is fast and stable, completely freeing the serial port from the limitation of the communication distance. Support dynamic IP and static IP, support gateway and proxy server, parameters can be set through browser.
Provides four 232/485/422 serial ports, eight DI channels, eight AI channels, six DO channels, and two Wiegand interfaces.
2. reliability:
(1) Dongfang digital product C2000 adopts double watchdog circuit design, which ensures safer operation of the converter and is more reliable.
(2) Eastern Digital's C2000's low work consumption, such low power will make the converter run without heat, so that the system and peripheral equipment without any influence, more stable operation;
(3) Dongfang Digital actively provides test software with automatic sending and receiving functions to customers, and urges users to continue testing the converters through the computer for a period of time. It promises that even if data of several tens or even hundreds of megabytes are transmitted, no data loss or error will be lost. ;
(4) Dongfang Digital provides three-month free replacement and five-year quality warranty service for the product C2000.
3. Ease of use:
(1) Dongfang Digital Products C2000 has a virtual serial port driver, the user's software can be used without any modification;
(2) Dongfang Digital provides communication dynamic libraries and dynamic libraries for users with high integration requirements, and the method of operation is simple, making the C2000 more user-friendly;
(3) Dongfang Digital can also provide users with a variety of development tools under the program source code, so as to facilitate the user's secondary development of the product.
