Alarm monitoring device for synchronous digital hierarchy (SDH) equipment

Abstract

The invention discloses an alarm monitoring device for synchronous digital hierarchy (SDH) equipment, which comprises an alarm signal acquisition module, an alarm and a centralized alarm interface module, wherein the alarm signal acquisition module is arranged on the rack of the SDH equipment, and comprises a first optoelectronic isolator; the first optoelectronic isolator is used for sensing alarm signals from the SDH equipment; the alarm is electrically connected with an alarm signal photoelectric acquisition unit and used for generating alarm information in accordance with the output of the alarm signal acquisition module; the centralized alarm interface module is electrically connected with the alarm signal acquisition module, and comprises a second optoelectronic isolator; and the second optoelectronic isolator is used for transmitting the alarm signals to a remote comprehensive network management system. The alarm monitoring device is utilized to skillfully acquire alarm management information without protocols or information models, thus realizing remote alarm management.

Description

technical field [0001] The invention relates to SDH equipment, in particular to a centralized alarm device for SDH equipment. Background technique [0002] SDH (Synchronous Digital Hierarchy) is a comprehensive information transmission network that integrates multiplexing, line transmission and switching functions, and is operated by a unified network management system. SDH is a technology applicable not only to optical fiber but also to microwave and satellite transmission. It can realize multiple functions such as effective network management, real-time service monitoring, dynamic network maintenance, and intercommunication between equipment from different manufacturers, which can greatly improve network resource utilization and reduce Management and maintenance costs, flexible, reliable and efficient network operation and maintenance are the focus of the development and application of transmission technology in the information field in today's world, and they are widely v...

AI Technical Summary

Problems solved by technology

[0003] However, in industrial production, SDH-based information systems and various types of production management, monitoring and control are diverse. Because the existing communication equipment interface protocols are difficult to obtain or the cost is high, it is difficult to achieve centralized monitoring.
