【摘要】：本文針對(duì)廣州蓄能水電廠視頻監(jiān)控系統(tǒng)展開研究與設(shè)計(jì)。本文設(shè)計(jì)的應(yīng)用于無(wú)人值守發(fā)電廠站的視頻監(jiān)控系統(tǒng),是根據(jù)視頻監(jiān)控的功能需求,按照“分層部署,逐層匯集”的設(shè)計(jì)原則,將系統(tǒng)結(jié)構(gòu)劃分成主站系統(tǒng)和站端系統(tǒng)。主站系統(tǒng)作為整個(gè)系統(tǒng)的集中管理平臺(tái),解決了遠(yuǎn)程監(jiān)控、分布存儲(chǔ)集中管理、報(bào)警提醒、多系統(tǒng)聯(lián)動(dòng)及系統(tǒng)管理等問題,實(shí)現(xiàn)了多功能、多業(yè)務(wù)集成的目標(biāo)。站端系統(tǒng)作為前端監(jiān)控設(shè)備的匯集點(diǎn),就近管理站內(nèi)前端設(shè)備,解決了集中存儲(chǔ)的瓶頸問題,實(shí)現(xiàn)了系統(tǒng)的分布式結(jié)構(gòu)和海量前端設(shè)備分區(qū)、分流管理,提高了系統(tǒng)的可靠性。由于視頻監(jiān)控系統(tǒng)在電力行業(yè)中具有重要作用,廣州蓄能水電廠對(duì)系統(tǒng)的穩(wěn)定性、實(shí)時(shí)性、存儲(chǔ)容量、供電可靠性等性能指標(biāo)提出了很高要求。根據(jù)電廠監(jiān)控范圍廣、現(xiàn)場(chǎng)環(huán)境復(fù)雜、數(shù)據(jù)存儲(chǔ)量巨大、生產(chǎn)場(chǎng)所電磁干擾大的現(xiàn)狀,本系統(tǒng)在設(shè)計(jì)和開發(fā)過程中需要重點(diǎn)解決存儲(chǔ)、傳輸和供電等問題。在系統(tǒng)存儲(chǔ)方面,本文采用基于iSCSI通信協(xié)議的IP-SAN網(wǎng)絡(luò)存儲(chǔ)技術(shù),提供儲(chǔ)備資源分配與管理,將現(xiàn)有的通信網(wǎng)與存儲(chǔ)網(wǎng)結(jié)合實(shí)現(xiàn)高速率傳輸和遠(yuǎn)距離數(shù)據(jù)共享;采用基于模塊化設(shè)計(jì)的SCSI-SATA磁盤陣列技術(shù)解決海量數(shù)據(jù)存儲(chǔ)和空間擴(kuò)展問題;通過合理的組網(wǎng)方式設(shè)計(jì)實(shí)現(xiàn)遠(yuǎn)程容災(zāi)備份,提高數(shù)據(jù)安全性。在系統(tǒng)傳輸和供電方面,根據(jù)施工場(chǎng)所現(xiàn)狀,本文提供了不同的選擇方式:長(zhǎng)距離使用光纖和收發(fā)器實(shí)現(xiàn)視頻信號(hào)傳輸,解決傳輸速率和電磁干擾問題;短距離使用普通雙絞線完成信號(hào)傳輸及控制,同時(shí)利用POE供電功能,降低施工難度;主站等設(shè)備集中的地方采用UPS不間斷電源集中供電,前端分散的設(shè)備采用POE供電或直接市電供電,提高系統(tǒng)供電穩(wěn)定性,減少系統(tǒng)建設(shè)和維護(hù)成本。通過對(duì)廣州蓄能水電廠視頻監(jiān)控系統(tǒng)的工程實(shí)踐和一年的試運(yùn)行驗(yàn)證,本系統(tǒng)運(yùn)行穩(wěn)定,年可用率≥99.9%,90%以上實(shí)時(shí)視頻畫面調(diào)出響應(yīng)時(shí)間≤2秒,視頻控制切換響應(yīng)時(shí)間≤2秒,前端設(shè)備控制延時(shí)≤2秒,數(shù)據(jù)存儲(chǔ)時(shí)間≥30天,信息處理準(zhǔn)確率達(dá)100%,并發(fā)訪問用戶數(shù)可達(dá)200人以上。系統(tǒng)具備高清視頻實(shí)時(shí)預(yù)覽、遠(yuǎn)程控制、環(huán)境信息監(jiān)測(cè)與報(bào)警、電子地圖、多系統(tǒng)聯(lián)動(dòng)和完善的系統(tǒng)管理等功能。經(jīng)過運(yùn)行效果評(píng)價(jià),本系統(tǒng)達(dá)到了設(shè)計(jì)目標(biāo),實(shí)現(xiàn)了通過現(xiàn)有的電力通信網(wǎng)對(duì)無(wú)人值守發(fā)電廠站進(jìn)行長(zhǎng)期有效的動(dòng)態(tài)監(jiān)控管理,提高了電廠運(yùn)行和維護(hù)的安全可靠性,為實(shí)現(xiàn)電網(wǎng)的可視化監(jiān)控和調(diào)度,建立無(wú)人值守發(fā)電廠站的遠(yuǎn)程維護(hù)、安全生產(chǎn)集中管控模式提供了基礎(chǔ)。
[Abstract]:This paper focuses on the research and design of video monitoring system for Guangzhou storage hydropower plant. The video monitoring system designed in this paper is based on the functional requirements of video monitoring, according to the "layered deployment," The system structure is divided into master station system and station end system. As the centralized management platform of the whole system, the master station system solves the problems of remote monitoring, distributed storage and centralized management, warning and warning. The multi-system linkage and system management have realized the goal of multi-function and multi-service integration. As the gathering point of front-end monitoring equipment, the station end system has solved the bottleneck problem of centralized storage by approaching the front-end equipment in the management station. The distributed structure of the system, the partition of massive front-end equipment, the distribution management and the reliability of the system are realized. Because the video surveillance system plays an important role in the electric power industry, the stability and real-time performance of the power plant in Guangzhou are analyzed. The storage capacity, power supply reliability and other performance indexes are very high. According to the current situation of wide monitoring scope, complex field environment, huge data storage and large electromagnetic interference in production sites, In the design and development of the system, it is necessary to solve the problems of storage, transmission and power supply. In the aspect of system storage, this paper adopts the IP-SAN network storage technology based on iSCSI communication protocol to provide the allocation and management of reserve resources. The existing communication network and storage network are combined to realize high-speed transmission and long-distance data sharing, and the SCSI-SATA disk array technology based on modular design is used to solve the problem of massive data storage and spatial expansion. The remote disaster recovery backup is realized by reasonable networking method, and the data security is improved. In the aspect of system transmission and power supply, according to the present situation of the construction place, This paper provides different options: long distance use of optical fiber and transceiver to achieve video signal transmission, to solve the transmission rate and electromagnetic interference problems, short distance using ordinary twisted pair to complete signal transmission and control, while using POE power supply function, In order to improve the stability of power supply system, UPS uninterruptible power supply is used in the place where the main station and other equipments are centralized, and the POE power supply or direct electricity supply is used in the front end scattered equipment, so as to improve the power supply stability of the system. The system construction and maintenance costs are reduced. Through the engineering practice of the video monitoring system of Guangzhou Pumped-storage Hydropower Plant and the test operation for one year, the system is running stably, the annual availability rate 鈮，
