【摘要】：本文論述了SDH傳輸設(shè)備在煤礦等特種行業(yè)的應(yīng)用實現(xiàn),SDH可以承載的通用數(shù)據(jù)信號包括以太網(wǎng)、CAN、RS232、RS485、語音業(yè)務(wù)以及SDH的基本傳輸單元E1信號等,基本可以涵蓋目前特種通信行業(yè)內(nèi)使用的數(shù)據(jù)信號種類。SDH是一種將數(shù)據(jù)復(fù)接、線路傳輸及交換功能融為一體、并由統(tǒng)一網(wǎng)管系統(tǒng)操作的綜合信息傳送網(wǎng)絡(luò)。SDH具有如下優(yōu)點：業(yè)務(wù)的實時監(jiān)控、網(wǎng)絡(luò)的動態(tài)維護、各個廠商設(shè)備間的網(wǎng)絡(luò)互通等,已在我國電信級骨干網(wǎng)絡(luò)中被廣泛采用,且價格越來越低。而目前煤礦等特種通信行業(yè)采用的主干網(wǎng)絡(luò)通信方式依舊是傳統(tǒng)的以太網(wǎng),隨著越來越多高質(zhì)量信號例如高清視頻的引入,以太網(wǎng)容易產(chǎn)生數(shù)據(jù)沖突的弊端越來越明顯,信號傳輸?shù)牟患皶r就可能帶來不必要的安全隱患,如果這類特種通信行業(yè)也能將SDH應(yīng)用到主干網(wǎng)絡(luò)通信中,那不僅實時性更好,安全性更高,同時也能非常方便的接入電信級主干網(wǎng)絡(luò),構(gòu)成物聯(lián)網(wǎng),極大的方便整體調(diào)度。本文主要內(nèi)容有：SDH技術(shù)應(yīng)用于煤礦等特種通信行業(yè)的研究背景、研究現(xiàn)狀和技術(shù)發(fā)展趨勢,SDH的基本原理；應(yīng)用于特種通信行業(yè)的SDH設(shè)備的設(shè)計目標(biāo)、技術(shù)指標(biāo)和整體設(shè)計方案；應(yīng)用于特種通信行業(yè)的SDH設(shè)備的硬件設(shè)計方法,選用意法半導(dǎo)體公司的STM32-ARM芯片作為主要管理芯片、Alter公司主流的Cyclone Ⅳ E系列EP4CE30-FPGA作為核心芯片進行電路功能設(shè)計,接口部分采用隔離模塊實現(xiàn)特種通信行業(yè)對于接口的要求；應(yīng)用于特種通信行業(yè)的SDH設(shè)備的嵌入式程序設(shè)計,包括操作系統(tǒng)、軟件架構(gòu)、功能實現(xiàn)等內(nèi)容；應(yīng)用于特種通信行業(yè)的SDH設(shè)備的網(wǎng)絡(luò)管理軟件設(shè)計方法,包括網(wǎng)元管理系統(tǒng)(EMS)、功能定義和實現(xiàn)、人機界面等內(nèi)容；應(yīng)用于特種通信行業(yè)的SDH設(shè)備的實現(xiàn)和調(diào)試等。本文設(shè)計實現(xiàn)的應(yīng)用于特種行業(yè)的SDH傳輸設(shè)備,具有實時性好,安全性高,容易接入電信級主干通信網(wǎng)絡(luò)等特點。
[Abstract]:This paper discusses the application and implementation of SDH transmission equipment in coal mine and other special industries. The general data signals that SDH can carry include Ethernet, CAN,RS232,RS485, voice service and E1 signal of basic transmission unit of SDH, etc. It can basically cover the types of data signals used in the current special communication industry. SDH is a kind of integration of data multiplex, line transmission and switching functions. The integrated information transmission network operated by the unified network management system. SDH has the following advantages: real-time monitoring of services, dynamic maintenance of the network, network interworking between the equipment of various manufacturers, and so on, which have been widely used in the telecommunications backbone network of our country. And the price is getting lower and lower. At present, the backbone network communication method used in coal mine and other special communication industries is still the traditional Ethernet. With the introduction of more and more high-quality signals such as high-definition video, the disadvantages of Ethernet data conflict are becoming more and more obvious. If the signal transmission is not timely, it may bring unnecessary security hidden dangers. If this kind of special communication industry can also apply SDH to the backbone network communication, it will not only have better real-time performance, but also have higher security. At the same time, it can also be very convenient to access the telecommunications level backbone network, forming the Internet of things, which is very convenient for overall scheduling. The main contents of this paper are as follows: the research background, research status and technical development trend of SDH technology applied in coal mine and other special communication industries, and the basic principles of SDH; The design goal, technical index and overall design scheme of SDH equipment used in special communication industry. The hardware design method of SDH equipment in special communication industry is carried out. The STM32-ARM chip of Italian semiconductor company is selected as the main management chip, and the mainstream Cyclone IV E series EP4CE30-FPGA of Alter company is used as the core chip to design the circuit function. In the interface part, the isolation module is used to realize the interface requirements of the special communication industry. Embedded program design of SDH devices used in special communication industry, including operating system, software architecture, function realization and so on. The design method of network management software for SDH equipment used in special communication industry includes the definition and implementation of (EMS), function of network element management system, man-machine interface and so on, and the realization and debugging of SDH equipment applied in special communication industry. The SDH transmission equipment designed and implemented in this paper has the characteristics of good real-time, high security and easy access to telecom backbone communication network.
