ST3000智能变送器与TPS系统通讯及维护[摘要]:阐述了智能变送器的结构及通讯原理,给出st3000智能变送器与tps系统间的通讯及其中维护心得体会。

[关键词]:智能变送器结构通讯中图分类号:tj768.4 文献标识码:tj 文章编号:1009-914x(2012)12- 0002–011、智能变送器结构st3000智能变送器由复合传感器和微处理器组成。

复合传感器是将差压、温度、静压三个传感器采用集成电路的扩散工艺生成在一个单晶硅片上,三个传感器的检测信号周期地读入微处理器,综合运算处理完成精确的压力、差压计算,一路经d/a数模转换器转换输出4—20ma,另一路经数字输入/输出部分与tps进行数据通讯。

2、t3000智能变送器与tps闸的通讯st3000智能变送器的两种输出方式可以通过现场智能通讯器(sfc)进行改变。

模拟量通讯模式用在智能变送器输出为模拟量,但需要和sfc进行通讯。

通讯模式采用半双工通讯方式,即“一问一答”不能同时进行。

数字量通讯模式用于智能变送器与tps的智能接品(sti)进行通讯,也用在智能变送器输出为数字量时与sfc 进行通讯。

2.1连接智能变送器用两芯屏蔽电缆接到tps系统高性能处理器hpm的接口模件(sti)所对应的现场端子(fta)上,fta向st3000现场表提供24vdc电源,电缆的屏蔽层接到机柜中的接地汇流条上,该汇流条与tps系统的工作地级相连。

2.2通讯变送器的发展方向是现场总线变送器,它与控制系统之间的通讯是数字化、双向的、多站的,是多台变送器共用二根传输线接到控制室。

honeywell11公司开发de数字增强协议,它采用波特率为220hz的低频电流脉冲,信号使用两个独立的电流脉冲4 ma、20 ma,分别代表逻辑“1”、“0”,数据用浮点的形式送入标准的双绞线,进行数字通讯时,回路中电流没有实际意义,不代表测量值。

它的特点是主从管理模式,即运行一台主机与一台现场仪表,它们之间实际数据双向传输。

智能变送器的应用特点及与HART协议通讯的互联分析

智能变送器的应用特点及与HART协议通讯的互联分析

智能变送器的应用特点(二)
♦ 智能变送器可以在手持通讯器上设定仪
表的零点和量程,因此仪表可以在不通 信号压力的情况下更改测量范围,这对 于现场情况较复杂的环境尤为方便;
♦ 智能变送器和DCS控制系统之间可实现
数字通讯,这就为全数字化的现场总线 控制系统提供了条件。
智能变送器的定义
在变送器中,仅仅增加了微处理器,是不能称 之为智能变送器的,只有当微处理器产生下列 功能后才能称为智能变送器:
♦ 具有双向通讯能力; ♦ 完善的自诊断功能; ♦ 优良的技术性能,包括可靠的传感器技术,宽
广的量程范围,以及稳定的压力和温度补偿。
智能变送器在现场的应用概况
♦ 中石化沧州分公司现场装置中应用的智
能变送器基本以富士FCX-AX、FCX-AII 系列、罗斯蒙特1151S、3051系列为主, 也有少量的横河EJA智能变送器在使用。
特殊应用场合下的注意事项
♦ 根据现场的特殊应用情况使用不同的FC
变送器,例如在中石化沧州分公司临氢 装置测量气液分离罐的液位,由于氢渗 透非常严重,而氢原子具有最小的原子 半径,容易在钢、铜等金属中扩散, 氢向应 力集中的部位扩散聚集,最终导致不锈钢 隔离膜片失去弹性,使得仪表最终无法 测量跟踪液位的变化。所以一般测量临 氢 介 质 应 选 择 3 1 6 L+ 镀 金 或 陶 瓷 + 镀 金 +316L的隔离膜片,避免氢脆现象的发生。
♦ 在现场中,一般冲洗油压力在4Mpa—8Mpa之间,不正
确的停表或不停表直接冲洗对变送器的膜盒冲击力是 不言而喻的。即使浮动膜盒会消减部分冲击力,但由 于大部分差压变送器最大量程范围在Kpa量级,所以仍 会对隔离膜片、保护膜片、测量膜片造成不可逆的损 伤,因此对于FC变送器在现场冲表时必须养成正确停 表的工作习惯,以避免不必要的损失。

ST 3000 Smart Pressure TransmitterSeries 900 Differential Pressure ModelsSTD9240 to 400 inH 2O 0 to 1,000 mbar STD930 0 to 100 psi 0 to 7,000 mbarSTD974 0 to 3000 psi0 to 210,000 mbar34-ST-03-652/08Specification and Model SelectionGuideIn 1983, Honeywell introduced the first Smart Pressure Transmitter ― the ST 3000®. In 1989, Honeywell launched for smart field devices. Today, its ST 3000 Series 900 Differentialproven “smart” technology to a wide spectrum of pressure measurement applications, from furnace combustion airflow rate to hydrostatic tank gauging. The ST 3000 S900 DifferentialPressure Transmitter can be used with any primary flow element to provide proven, repeatable flow measurement.All ST 3000 transmitters can provide a 4-20 mA output, Honeywell DigitallyEnhanced (DE) output, HART ®output, or F OUNDATION™ Fieldbus output. When digitally integrated with Honeywell’s Process Knowledge System™, EXPERION PKS™,ST 3000 instruments provide a more accurate process variable as well as advanced diagnostics.Honeywell’s cost-effective ST 3000 S900 transmitters lead the industry in reliability and stability:• Stability = ±0.01% per year • Reliability = 470 years MTBFFigure 1—Series 900 Differential Pressure Transmitters feature proven piezoresistive sensor technology.The devices provide comprehensive self-diagnostics to help users maintain high uptime, meet regulatory requirements, and attain high quality standards. S900 transmitters allow smart performance at analog prices. Accurate, reliable and stable, Series 900 transmitters offer greater turndown ratio than conventional transmitters."Honeywell transmitters operating in the digital mode usingHoneywell's Digitally Enhanced (DE) protocol make diagnostics available right at the control system's human interface. Equallyimportant, transmitter status information is continuously displayed to alert the operator immediately of a fault condition. Because the process variable (PV) status transmission precedes the PV value, we are guaranteed that a bad PV is not used in a control algorithm. In addition, bi-directional communication provides for remotetransmitter configuration directly from the human interface, enabling management of the complete loop.”Maureen Atchison, DuPontSite Electrical & Instrumentation LeaderIntroduction34-ST-03-65Page 2DescriptionFeaturesThe ST 3000 transmitter can replace any 4 to 20 mA output transmitter in use today and operates over a standard two-wire system.The measuring means is a piezoresistive sensor, which actually contains three sensors in one. It contains a differential pressure sensor, a temperature sensor, and a static pressure sensor.Microprocessor-based electronics provide higher span-turndown ratio, improved temperature and pressure compensation, and improved accuracy.The transmitter’s meter body and electronics housing resist shock, vibration, corrosion, and moisture. The electronics housing contains a compartment for the single-board electronics, which is isolated from an integral junction box. The single-board electronics is replaceable and interchangeable with any other ST 3000 Series 100 or Series 900 model transmitter.Like other Honeywell transmitters, the ST 3000 features two-way communication and configuration capability between the operator and the transmitter through several Honeywell field-rated portable configuration devices, including the Smart Field Communicator (SFC) and the Multiple Communication Configurator (MC ToolKit). While both are made for in-field use, the MC Toolkit also can be ordered for use in intrinsically safe environments.The SCT 3000 Smartline® Configuration Toolkit provides an easy way to configure instruments using a personal computer. The toolkit enables configuration of devices before shipping or installation. The SCT 3000 can operate in the offline mode to configure an unlimited number of devices. The database can then be loaded down-line during commissioning. •Choice of linear or square root output conformity is asimple configuration selection. •Direct digital integration with Experion PKS and othercontrol systems provides localmeasurement accuracy to thesystem level without addingtypical A/D and D/A converterinaccuracies.•Unique piezoresistive sensor automatically compensatesinput for temperature andstatic pressure. Added “smart”features include configuringlower and upper rangevalues, simulating accurateanalog output, and selectingpreprogrammed engineeringunits for display.•Smart transmitter capabilities with local or remoteinterfacing means significantmanpower efficiencyimprovements incommissioning, start-up, andongoing maintenancefunctions.34-ST-03-65Page 3SpecificationsOperating Conditions – All ModelsParameterReference Condition (at zero static)Rated ConditionOperative LimitsTransportation andStorage°C °F °C °F °C °F °C °F Ambient Temperature25 ±1 77 ±2-40 to 85-40 to 185 -40 to 85 -40 to 185 -55 to 125-67 to 257Meter Body Temperature 25 ±177 ±2 -40 to 1101-40 to 2301-40 to 125-40 to 257 -55 to 125-67 to 257Humidity %RH10 to 55 0 to 100 0 to 100 0 to 100Vacuum Region - Minimum Pressure mmHg absolute inH 2O absolute Atmospheric Atmospheric25 132 (short term 2) 1 (short term 2)Supply Voltage, Current, and Load ResistanceVoltage Range: 10.8 to 42.4 Vdc at terminals Current Range: 3.0 to 21.8 mALoad Resistance: 0 to 1440 ohms (as shown in Figure 2)Maximum Allowable Working Pressure (MAWP) 4(ST 3000 products are rated to Maximum Allowable Working Pressure.

TDC3000(TPS)系统简介
TDC3000X开放而安全的生产与过程控制系统:
•强大与多样性
TDC3000集散控制系统,它是TotalPlant全厂一体化开放概念里的一个平台。

通过一个创新的系统结构和开放的通讯环境,TDC3000将过程和现场仪表的管理(控制层)与生产和信息的管理(信息
层)集成在一起,形成一个信息与控制的集成系统。

由此,通过一个单一窗口就可以为企业管理者提供各类数据,辅助他们及时地作出经营决策;同时,系统的通用性和可靠性确保了过程运作的安全进行。

•开放与安全性
控制层与信息层的结合,主要是靠系统内的两种双处理器模件--------万能工作站(UxS)与应用模件(AxM)来实现。

这两种模件形成了TDC3000结构中称为X-LAYER的X层。

UxS是TDC3000系统的用户界面,符合X WINDOWS/MOTIF工业标准,它向操作者和工程师提供了一
个面向现场过程控制与全厂信息的统一窗口;AxM是TDC3000系统内一个高性能且可靠的应用平台,可执行专用的或开放的应用软件。

这两种模件均使用RISC处理器工作站技术,运行UNIX操作系统。

由于使用标准的开放通讯协议,可以连接于信息层,它们同时支持Honeywell及其它厂家和用户自行开放的应用软件,也保证对未来硬件平台的迁移性。

对于安全性,UXS和AXM可对全厂信息网络(PIN)可能发生的问题对控制层进行保护。

例如,它们可以防止未经授权而进入系统,避免无意的改变数据库信息,阻止通讯或网络节点故障以及信息层内软件错误影响控制程。

TDC3000组成:
TDC3000系统由三大通讯网组成:LCN局域控制网,UCN通用控制网,DATA HIWAY高速数据公路。

每种网上挂有不同功能的模件,如CG、PLNM、AM、US、UXS、HM、UWS、HG、NIM、PLCG、NG、PM、PLC、APM、LM,实现了分散控制集中管理的控制系统。

•LCN网是TDC3000系统的主干网,该网符合IEEE802.4标准,采用“令牌总线”协议。

挂接在LCN 网上的模件主要有:
US 通用操作站,主要功能分为操作员功能、工程师功能和维护人员功能。

操作员功能是,监视或控制生产过程,处理报警,显示、打印报表报告趋势,监视系统状态,流程画面显示。

工程师功能是系统网络组态、过程组态、区域数据库组态,流程图绘制,编制自由报表,编写控制程序。

•UWS 通用工作站,是TDC3000系统的又一个人-机接口,具有US 的全部功能,它主要为工厂办公室管理设计的。

UXS 带UNIX系统的通用操作站,其功能与 US 基本相同,它是多窗口开放式的操作站。

可与上层的PIN工厂信息网通讯。

AM 应用模块,是用来完成UCN和 DATA HIWAY 网络上所连接的模件不能完成的高级控制功能、复杂及多变量运算功能,提高过程控制及管理水平。

•HM历史模块,是TDC3000系统的存储单元,它可存储过程报警、操作员状态改变、操作员信息,系
统状态改变、系统维护及提示信息,连续过程历史数据等。

另外,还存储系统文件,确认点文件及在线维护信息。

NIM网络接口模块、HG高速通道接口、CG计算机接口,是LCN网络与UCN网络DATA HIWAY 网络以及上位计算机(如DEC VAX 等)进行通信的接口模件。

•PLNM 工厂信息网络接口,是LCN与PIN网络进行通信的接口模件。

•PLCG 可编程控制器接口,是LCN与PLC可编程控制器进行通信的接口模件。

•UCN通用控制网络和逻辑管理站(LM)、过程管理站(PM)、先进过程管理站(APM),是新型的过程控制和数据采集系统,采用IEEE802.4标准通讯协议。

通用控制网络(UCN),它遵循IEEE802.2和802.4标准,具有5兆的传输速率,采用令牌总线通讯方式,是一个高性能的、实时的MAP协议基础上的过程控制网络,它提供工业生产所要求的冗余性、、可靠性和安全性。

UCN与LCN的时钟同步,并在UCN网上广播,这就保证了APM所具有的功能,如每毫秒事件顺序(DI SOE)数字输入的监测功能,有高精度时间分辨率。

全部监控点都在US、UxS上显示。

UxS、US采用触摸屏方式以及专用工程师键盘来操作,操作台有报警提示。

局域控制网(LCN)为冗余结构,从UxS接出的LAN 网用于不同地点监视一个集成系统提供方便。

冗余的过程控制网(UCN)连接控制设备和控制器。

模拟量输入,模拟量输出,数字量输入,数字量输出I/O板处理器用于将现场设备的监控信号接入APM。

串行I/O处理器(SIOP)用于子系统接口,如壳装设备的PLC和低压开关柜。
