【摘要】：随着光纤线路的普及,光纤通信的服务质量成为运营商们关注的焦点,因此设计一个可靠、高效的保护体系来保证光纤网络通信的安全、畅通运营对各个运营商来说非常重要。光保护设备以其快速可靠、安全灵活、业务恢复能力强等优点在光纤通信领域的应用,很大程度上解决了运营商的难题。光保护设备全称是光纤线路自动切换保护设备(OLP),两条光纤线路与两块光保护设备连接组成光保护传输系统,光保护传输系统选择其中的某条光纤线路作为主用光纤,另一条将作为系统备用光纤,备用光纤将传输次一级信号。当主用线路光纤发生故障或通信质量下降时,主用线路光保护设备的接收端会监测到光纤光功率下降,系统将自动将传输信息路由从原来的主用线路切换到备用路线,而系统另一端的光保护设备将同步的从主用线路切换到备用光纤线路上,从而保证了通信线路的正常工作,有效预防光纤或设备故障。然而大量光保护设备在光纤领域的应用对于设备管理人员和光纤维护人员来说是个不小的挑战。因此,根据光保护设备的特点,研究和设计光保护设备实时监控系统具有重要的现实意义。光保护设备实时监控系统,结合了多线程和线程池技术、Websocket实时通信技术和SVG矢量图形技术等,实现了光保护设备实时监控的设计功能。本文重点研究了多线程和线程池技术、Websocket实时通信技术和SVG矢量图形技术在光保护设备实时监控系统中的应用。首先,采用xml格式制定了光保护设备实时采集服务器和系统服务器之间的通信协议。其次,采用多线程和线程池技术实时处理采集服务器发往系统服务器的实时数据,同时将处理过的实时数据采用Websocket实时通信技术实时传输到客户端。再次,采用SVG矢量图形技术设计光保护设备、机箱等相关设备图元函数,同时和数据库中设备数据信息结合在客户端以图形方式显示。最后,实时数据和客户端SVG图元结合在客户端动态显示。通过光保护设备实时监控系统,可以实时了解到各段光纤的运行状态,为光纤维护人员提供了极大的便利。
[Abstract]:With the popularity of optical fiber lines, the quality of service of optical fiber communication has become the focus of attention of operators. Therefore, it is very important to design a reliable and efficient protection system to ensure the security of optical network communications. The application of optical protection equipment in the field of optical fiber communication with its advantages such as fast reliability, flexible security, strong service recovery ability and so on, has solved the problem of operators to a great extent. The full name of the optical protection equipment is the optical fiber line automatic switch protection equipment (OLP), two optical fiber lines are connected with two optical protection devices to form the optical protection transmission system. The optical protection transmission system selects one of the optical fiber lines as the main optical fiber. The other will be used as a backup fiber for the system, which will transmit the secondary signal. When the optical fiber of the main line fails or the communication quality drops, the receiver of the optical protection device of the main line will monitor the optical power drop of the optical fiber, and the system will automatically switch the transmission information route from the original main line to the standby route. The optical protection equipment at the other end of the system switches synchronously from the main line to the standby optical fiber line, which ensures the normal operation of the communication line and effectively prevents the fiber or equipment from malfunction. However, the application of a large number of optical protection devices in the field of optical fiber is a great challenge for equipment managers and optical fiber maintainers. Therefore, according to the characteristics of optical protection equipment, it is of great practical significance to study and design the real-time monitoring system of optical protection equipment. The real-time monitoring system of optical protection equipment, which combines multi-thread and thread pool technology, Websocket real-time communication technology and SVG vector graphics technology, realizes the design function of real-time monitoring of optical protection equipment. This paper focuses on the application of multi-thread and thread pool technology, Websocket real-time communication technology and SVG vector graphics technology in the real-time monitoring system of optical protection equipment. Firstly, the communication protocol between the real-time acquisition server and the system server of optical protection equipment is established with xml format. Secondly, multithreading and thread pool technology are used to process the real-time data sent from the server to the system server, and the processed real-time data is transmitted to the client by Websocket real-time communication technology. Thirdly, SVG vector graphics technology is used to design the image element function of optical protection equipment, chassis and other related equipment. At the same time, it combines with the equipment data information in the database to display in the client in a graphic way. Finally, the real-time data and the client-side SVG elements are dynamically displayed in the client. Through the real-time monitoring system of optical protection equipment, the operating state of each optical fiber can be realized in real time, which provides great convenience for the maintenance of optical fiber.
