Computer room monitoring system scheme based on TCP/IP network
----- You can use Oriental Digital 1 / 2 / 4 / 8 serial port networking server
I. Introduction
The centralized monitoring system for power environment is used for telemetering, remote sensing, and remote control of various parameters, images, sounds, etc. of switching power supplies, air conditioners, oil machines, batteries, high and low voltage power distribution, and other equipment and environments of distributed communication bureaus (stations). Real-time monitoring of its operating parameters, diagnosis and processing of faults, recording and analysis of relevant data, so as to achieve the purpose of a small or unattended communications bureau (station), and centralized monitoring of equipment, centralized maintenance and centralized management.
II Status of Existing Monitoring Systems
The main transmission methods of the local network monitoring system are DDN, Modem, ISDN, and 2 Mbit/s private lines, all of which are point-to-point transmissions. Considering that the DDN and 2 Mbit/s leased line resources in the access network are limited, the real-time monitoring performance of the Modem and ISDN transmission modes is not stable. If point-to-point transmission is used, there are too many central equipments and the operating and maintenance costs are too high. Therefore, most systems today are 2 Mbit/s extraction slot mode.

The network status of the control system is shown in the figure: 
III Monitoring System Based on TCP/IP Network Transmission
With the development of broadband networks, it becomes easier and easier to obtain broadband network resources at various access points. By using these broadband network resources and adopting the TCP/IP method, access points can easily establish contact with the monitoring and management center and the database, and at lower cost, the power equipment, room environment, security, and fire protection of access points can be used. The video and other information are monitored under a unified platform.
The system based on TCP/IP network transmission mode is shown in the figure:
On the site of the telecommunications access network equipment room, a TCP/IP-based on-site serialized networking server unified monitoring platform was set up to centrally monitor the power equipment, computer room environment, and security and fire protection systems in batches. The various devices, serial ports, and protocols of each system can be integrated. It is possible to directly access the access point network rooms through the serial port software to implement monitoring. Due to the establishment of a unified platform, after an investment, only gradually add external serial devices, you can gradually complete the power equipment, computer room environment, security and fire protection, the system based on the TCP / IP network structure of centralized monitoring.
IV Comparison between 2Mbit/s extraction time slot and TCP/IP network
Application category
Using 2Mbit/s extraction time slot
Using TCP/IP network
Price cost
The time slot card is relatively expensive, and both ends of the SU and the data collector are loaded with a time slot card, and the cost is relatively high.
Serial server is lower in price compared to serial server. Only one serial server can be loaded on the data collector to achieve communication between them.
transfer speed
Slower transmission
Faster transmission speed
Commissioning and maintenance
Can not determine the cause of the fault in a timely manner, it is not clear where the line and the line at both ends of the fault
Simple and convenient commissioning and maintenance
Networking
Network is not flexible
Flexible networking
Five East Digital Product C2000 Performance Features
1. Features:
C2000 can realize the function of directly converting serial port data transmission to TCP/IP data transmission. After packing the serial port data of the SM end of the system, it can be easily put on the network, and then it can be quickly and steadily transmitted to the SU end through the TCP/IP network, resulting in more transmission performance. Fast and stable.
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.
