【摘要】：隨著光纖線路的普及,光纖通信的服務(wù)質(zhì)量成為運(yùn)營(yíng)商們關(guān)注的焦點(diǎn),因此設(shè)計(jì)一個(gè)可靠、高效的保護(hù)體系來保證光纖網(wǎng)絡(luò)通信的安全、暢通運(yùn)營(yíng)對(duì)各個(gè)運(yùn)營(yíng)商來說非常重要。光保護(hù)設(shè)備以其快速可靠、安全靈活、業(yè)務(wù)恢復(fù)能力強(qiáng)等優(yōu)點(diǎn)在光纖通信領(lǐng)域的應(yīng)用,很大程度上解決了運(yùn)營(yíng)商的難題。光保護(hù)設(shè)備全稱是光纖線路自動(dòng)切換保護(hù)設(shè)備(OLP),兩條光纖線路與兩塊光保護(hù)設(shè)備連接組成光保護(hù)傳輸系統(tǒng),光保護(hù)傳輸系統(tǒng)選擇其中的某條光纖線路作為主用光纖,另一條將作為系統(tǒng)備用光纖,備用光纖將傳輸次一級(jí)信號(hào)。當(dāng)主用線路光纖發(fā)生故障或通信質(zhì)量下降時(shí),主用線路光保護(hù)設(shè)備的接收端會(huì)監(jiān)測(cè)到光纖光功率下降,系統(tǒng)將自動(dòng)將傳輸信息路由從原來的主用線路切換到備用路線,而系統(tǒng)另一端的光保護(hù)設(shè)備將同步的從主用線路切換到備用光纖線路上,從而保證了通信線路的正常工作,有效預(yù)防光纖或設(shè)備故障。然而大量光保護(hù)設(shè)備在光纖領(lǐng)域的應(yīng)用對(duì)于設(shè)備管理人員和光纖維護(hù)人員來說是個(gè)不小的挑戰(zhàn)。因此,根據(jù)光保護(hù)設(shè)備的特點(diǎn),研究和設(shè)計(jì)光保護(hù)設(shè)備實(shí)時(shí)監(jiān)控系統(tǒng)具有重要的現(xiàn)實(shí)意義。光保護(hù)設(shè)備實(shí)時(shí)監(jiān)控系統(tǒng),結(jié)合了多線程和線程池技術(shù)、Websocket實(shí)時(shí)通信技術(shù)和SVG矢量圖形技術(shù)等,實(shí)現(xiàn)了光保護(hù)設(shè)備實(shí)時(shí)監(jiān)控的設(shè)計(jì)功能。本文重點(diǎn)研究了多線程和線程池技術(shù)、Websocket實(shí)時(shí)通信技術(shù)和SVG矢量圖形技術(shù)在光保護(hù)設(shè)備實(shí)時(shí)監(jiān)控系統(tǒng)中的應(yīng)用。首先,采用xml格式制定了光保護(hù)設(shè)備實(shí)時(shí)采集服務(wù)器和系統(tǒng)服務(wù)器之間的通信協(xié)議。其次,采用多線程和線程池技術(shù)實(shí)時(shí)處理采集服務(wù)器發(fā)往系統(tǒng)服務(wù)器的實(shí)時(shí)數(shù)據(jù),同時(shí)將處理過的實(shí)時(shí)數(shù)據(jù)采用Websocket實(shí)時(shí)通信技術(shù)實(shí)時(shí)傳輸?shù)娇蛻舳�。再�?采用SVG矢量圖形技術(shù)設(shè)計(jì)光保護(hù)設(shè)備、機(jī)箱等相關(guān)設(shè)備圖元函數(shù),同時(shí)和數(shù)據(jù)庫(kù)中設(shè)備數(shù)據(jù)信息結(jié)合在客戶端以圖形方式顯示。最后,實(shí)時(shí)數(shù)據(jù)和客戶端SVG圖元結(jié)合在客戶端動(dòng)態(tài)顯示。通過光保護(hù)設(shè)備實(shí)時(shí)監(jiān)控系統(tǒng),可以實(shí)時(shí)了解到各段光纖的運(yùn)行狀態(tài),為光纖維護(hù)人員提供了極大的便利。
[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.
