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.
The status of the existing monitoring system
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 current status of the monitoring system network is shown in the figure:
Three monitoring systems 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 extracted time slot and TCP/IP network
The application class uses 2 Mbit/s to extract time slots. It adopts TCP/IP network. The price and cost of the time slot card are relatively high. Moreover, both ends of the SU and the data collector must be loaded with the time slot card. The cost is relatively high. Lower than the price, in the data collector side only need to load a serial server to achieve the communication speed between them. The transmission speed is slower. The transmission speed is faster. The debugging and maintenance cannot determine the cause of the fault in time. It is not clear whether the line and the line are two. End-of-Site Troubleshooting Debugging and Maintenance Simple and Efficient Networking Modes Networking Modes Inflexible Networking Flexibility Performance Features of C2000 Digital Products
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.
reliability:
(1) Dongfang digital product C2000 adopts double watchdog circuit design, which ensures safer operation of the converter and is more reliable.
