Adapt 3 g power environment centralized monitoring system features (1)

As China Mobile TD trial network bidding process starts, the domestic 3 g network construction entered a substantive stage.

During the Beijing Olympics 2008, China will have 10 cities enabled 3 g technology in the mobile network. With the 3 g network construction and put into operation, various data services, multimedia business application will become increasingly common, and the first two 3G equipment and equipment compared to the use of generations more advanced technology, the more integrated products; in this case, the device on which to run the environment made more stringent requirements. How to ensure the normal operation of the network devices, in-room, base station power equipment, environment of exceptional conditions, how to quickly and accurately locate and troubleshoot the network operation and maintenance, is the focus of all is that 3 g system an important prerequisite for successful development.

Power environment centralized monitoring system as an important means of network operation and maintenance, responsible for the equipment operation environment, power equipment health monitoring tasks, complete data storage and smart analysis, fault for fast and accurate positioning, providing early warning and advance an important basis for decision-making.

Ring monitoring system development, architecture and standards?

1 history

Power environment centralized monitoring system from the start of the 1990s, after ten years of development, has become the network operation and maintenance system.

From the initial development of dry contact way gradually to the current analog monitoring, video surveillance, data collection and automation, data analysis, intelligent, user-friendly user interface for network operation/maintenance downsize provides a strong guarantee. The major operators have had against the construction of the existing network ring centralized monitoring system, but between the various operators in the network size, system, application and network technology is also a difference.

2 framework features

Power environment centralized monitoring system consists of the acquisition subsystem, transport subsystem and the network management subsystem consisting of three parts.

Acquisition subsystem through the sensor and transmitter complete non-intelligent device signal acquisition and ADCs, through intelligent device interface complete smart device Protocol parsing; network management subsystem complete data analysis, storage, presentation, and other functions; transport subsystem is acquisition subsystem and the network management subsystem, a bridge between the data transfer.

Ring system monitor object can be divided into environment and power equipment two broad categories: environmental class including temperature, humidity, smoke, flooding, a magnetic belt, red outside ... etc; power equipment includes high-voltage power distribution, low-voltage distribution, combining power, battery, UPS, units, air conditioners, etc.

Ring monitoring system generally use three-level networking, and General construction in regional monitoring Center (LSC), direct access to the monitored base station on-site monitoring unit (FSU); at the provincial level construction centralized monitoring Center (CSC), complete the LSC's access, achieving a unified centralized monitoring throughout the province.

3 standard

Ring monitoring industry standards have two, one is the development of initial YDN 023-1996 communication power supply and conditioning monitoring system technical requirements (temporary provisions) Act, is to monitor the industry's first standard; the second is the 2005 information industry Ministry published YD/T 1363-2005 the communication Council (stations) power supply, air conditioning and environment centralized monitoring and management system ", the standard for standard series comprises four parts: the first part of the technical requirements for the system, the main provisions of the Constitution, the system monitor object and the content, functionality, requirements, system software and hardware reliability requirements; the second part of the Internet Protocol, the provisions of the interface and C, and D interface protocol; the third is divided into front end smart device Protocol, i.e. A interface protocol; the fourth part of the test method.

At the same time intelligent access control system, image monitoring system of the relevant industry standards are also developed.
