【正文】 全線數(shù)據(jù)采集和監(jiān)控系統(tǒng)采用光纜通信信道作為主信道，租用郵電公網(wǎng)作為調(diào)度控制中心與 SCS 的備用信道。 *MCC and SCC will municate with each SCS and RTU by optical fiber munications system（ DDN is standby munication system）， MCC will municate with SCC using optical fiber munications system as main channel and DDN as standby channel and sent the relevant realtime information to SCC at the same time (using optical fiber cable as main channel and DDN as standby channel). The data adoption and supervision system adopt fiber munications as main channel and DDN as standby channel. There are not standby channel between control center with RTU. RTU facilities must have the function of transporting data to the control system of process station upstream and downstream as to carry out the standby munication. *烏魯木齊調(diào)度控制中心和蘭州備用調(diào)控中心通過(guò)光纖通信系統(tǒng)（ DDN 為備用通信系統(tǒng)）與各個(gè)工藝站場(chǎng)的站控系統(tǒng)（ SCS）和 RTU 互聯(lián)，各個(gè)工藝站場(chǎng)的站控系統(tǒng)（ SCS）和 RTU 同時(shí)將數(shù)據(jù)實(shí)時(shí)傳送到烏魯木齊調(diào)度控制中心和蘭州備用調(diào)控中心。 SCS mainly consists of puter work system, PLC, operator workstations and munication facilities. 站控系統(tǒng)（ SCS）主要由計(jì) 算機(jī)網(wǎng)絡(luò)系統(tǒng)、可編程邏輯控制器（ PLC——Programmable Logical Controller）、操作員工作站及進(jìn)行數(shù)據(jù)傳輸?shù)耐ㄐ旁O(shè)備組成。 SCS and RTU are served as a remote control unit of SCADA system and they are a base which guarantees the normal running of SCADA system. They are the remote actuators of MCC used for dispatching, managing, control mands, therefore they are the most important 第 18 頁(yè) 共 144 頁(yè) monitoring level of SCADA system. SCS and RTU independently collect data and control at the technological stations, but also transfer the relevant message to MCC and receive the mands from it. SCS 和 RTU 作為 SCADA 系統(tǒng)的遠(yuǎn)方控制單元，是保證 SCADA 系統(tǒng)正常運(yùn)行的基礎(chǔ)，為調(diào)度控制中心調(diào)度、管理與控制命令的遠(yuǎn)方執(zhí)行單元，是 SCADA 系統(tǒng)中最重要的監(jiān)控級(jí)。 Station Control System (SCS) of SCADA system is used for the station by man on duty and Remote Terminal Unit (RTU) for the station by no one on duty. 管道沿線有人值守的工藝站場(chǎng)設(shè) SCADA 站控系統(tǒng)（ SCS—— Station Control System）。調(diào)度控 制中心位于新疆烏魯木齊市，后備控制中心位于甘肅省蘭州市。 PROJECT OVERVIEW 工程概況 Automation control system is based on SCADA system in order to assure that the pipeline performance will be in a status of high safety, credibility, stability, efficiency, and economy. The pipeline is offering a SCADA system with a Master/Main control center (MCC) in Urumchi and a Standby control center (SCC) in Lanchow. 為了保證該輸油管道安全、可靠、平穩(wěn)、高效、經(jīng)濟(jì)地運(yùn)行，對(duì)于該輸油管道的自動(dòng)控制系統(tǒng)采用以計(jì)算機(jī)為核心的全線監(jiān)控和數(shù)據(jù)采集（ SCADA）系統(tǒng)。 Standards and codes of (including standard and codes issued by relevant ministries) 中華人民共和國(guó)標(biāo)準(zhǔn)和規(guī)范 （ 包括部頒標(biāo)準(zhǔn)和規(guī)范 ） No. 標(biāo)準(zhǔn)號(hào) Title 題目 GB501831993 原油和天然氣工程設(shè)計(jì)防火規(guī)范 GB502532020 輸油管道工程設(shè)計(jì)規(guī)范 GB500581992 爆炸和火災(zāi)危險(xiǎn)環(huán)境電力裝置設(shè)計(jì)規(guī)范 GB 爆炸性氣體環(huán)境用電氣設(shè)備 第 1 部分：通用要求 GB 爆炸性氣體環(huán)境用電氣設(shè)備 第 2 部分：隔爆型“ d” GB 爆炸性氣體環(huán)境用電氣設(shè)備 第 4 部分：本質(zhì)安全型“ i” GB 42081993 外殼防護(hù)等級(jí)的分類 GB 28872020 計(jì)算站場(chǎng)地技術(shù)條件 GB/T 93611988 計(jì)算站場(chǎng)地安全要求 GB 72602020 不間斷電源設(shè)備 GB 501161998 火災(zāi)自動(dòng)報(bào)警系統(tǒng)設(shè)計(jì)規(guī)范 GB 501741993 電子計(jì)算機(jī)機(jī)房設(shè)計(jì)規(guī)范 GB 500932020 工業(yè)自動(dòng)化儀表工程施工及驗(yàn)收規(guī)范 GBJ 1311990 自動(dòng)化儀表安裝工程質(zhì)量檢驗(yàn)評(píng)定標(biāo)準(zhǔn) 其他國(guó)家和機(jī)構(gòu)的標(biāo)準(zhǔn)和規(guī)范 ： No. 標(biāo)準(zhǔn)號(hào) Title 題目 ANSI/ Instrumentation Symbols and Identification Instrument Loop Diagrams Graphic Symbols for DCS/Shared display Instrumentation Logic and Computer system API 1130 Computational Pipeline Monitoring for Liquid Pipelines 第 16 頁(yè) 共 144 頁(yè) API RP 1119 Training and Qualification of Liquid Pipeline Operators API PUBL 1149 Pipeline Variable Uncertainties and Their Effects on Leak Detectability API PUBL 1155 Evaluation Methodology for Software Based Leak Detection Systems NFPA70 National Electric Code (NEC) ISA RP Hardware testing of digital process puters ISA S Environmental conditions for process measurement and control systems: Airborne contaminants IEC600529 Degree of protection provided by enclosure (IP Code) IEC60079 Electrical apparatus for explosive gas atmospheres IEC 60068 SET Environmental testing IEC6006821.
