智能定位器调节阀通过HART通讯实现运行监控

智能定位器调节阀通过HART通讯实现运行监控

智能定位器调节阀通过HART通讯实现运行监控发布时间:2021-08-03T06:41:09.914Z 来源:《电力设备》2021年第5期作者:刘卓[导读] 可以大大提高维修效率,减少维修及停机时间,降低维修成本。

(中国石油哈尔滨石化分公司仪电车间)摘要:智能定位器调节阀在线监测、诊断、组态、校验等,实行一体化管理方案,对调节阀的实际状况进行实时性监控及处理,能够提供准确有效的数据,编制有针对性的维修策略。

以Honeywell的PKS系统模拟量输出AO卡为基础,通过HART通讯,采集智能定位器实时运行数据,实现调节阀在线监测与诊断,达到调节阀预知维修的目的。

中关键词:预知维修;智能定位器;调节阀;HART通讯;模拟量输出AO卡;阀门监控前言工业4.0时代下,利用大数据以及智能仪表的数据分析而推出的预知性维修,已经成为发展趋势。

智能定位器调节阀在线监测、诊断、组态、校验等,实行一体化管理方案,对调节阀的实际状况进行实时性监控及处理,能够提供准确有效的数据,编制有针对性的维修策略,使调节阀的维护更加方便可靠。

可以大大提高维修效率,减少维修及停机时间,降低维修成本。

一、调节阀专业维修存在的短板现阶段,调节阀专业维修工作主要以“事后维修”为主,“预防维修”为辅,不能有效开展预知维修工作。

主要体现在以下方面:1.机械式定位器调节阀,通过DCS系统完成基本的调节控制。

缺乏对调节阀本体的实时监测功能,缺乏对调节阀运行状况变化的分析与预测功能。

对于调节阀卡涩、动作偏差、运行缓慢故障等不能进行预警。

2.智能定位器调节阀,虽然支持HART协议,但未能实现与DCS系统的实时通讯,缺乏对调节阀本体的实时监测功能。

在日常工作中,维护人员只能以“点对点”模式进行维护。

利用手操器,在现场对单台智能定位器进行参数整定、自动校验等操作,效率低下。

而且,智能定位器的自诊断、在线组态、在线校验等功能,未能与DCS系统相互融合,未能充分发挥智能定位器的作用,DCS系统缺乏对整套装置智能定位器集中监测管理的功能。

什么是无线HART?
无线HART 是基于IEEE 802.15.4,可在全球应用的 2.4GHz 频带,具有信道跳频、Mesh网络拓扑鲁棒性和 信息安全的低功耗无线通信规范。它旨在为过程测量和控 制提供有足够确定性、并具有可互操作性的无线通信标准。
将无线通信纳入HART规范,将在HART原有一切功能的 基础上进一步提升具有HART功能的现场仪表和主系统的 技术能力。 这就是说,有线HART和无线HART除了通信介质不同而 产生的必要规范而外,它们运用同样的HART命令结构、 同样的软件工具。

H A RT技术指南12smar在智能设备系统中,H A RT 通讯协议的好处介绍H A RT 现场通讯协议是工业界广泛认可的标准,在4-20mA 智能设备的基础上增加了数字通讯能力。

该技术的普及使用非常迅速,目前,事实上所有主要设备供应商都H A RT 提供协议产品。

H A RT 协议是唯一向后兼容的智能仪表解决方案,在一条电缆上可以同时传递4-20mA 模拟信号和数字信号。

H A RT 在提供现场总线的好处时,保留对现有4-20mA 系统的兼容性。

本文进行H A RT 协议的概要介绍及该项技术的主要优势。

具统计,每台设备在安装调试初期节约成本 $300-500,并且在每年节约维护和运行成本 $100-200。

模拟 + 数字通讯许多年以来,过程自动化设备使用的现场通讯标准是毫安模拟电流信号。

在大多数应用中,正比于所代表的过程参数,毫安信号在4-20mA 之间变动。

事实上,所有已安装的工厂仪表系统都使用这一国际标准同过程变量信息通讯。

H A RT 现场通讯协议扩展了4-20mA 标准,在智能测量和控制仪表的基础上提高了通讯能力。

作为过程控制演变的重要一步,HART 协议促进了过程仪表功能的大幅度革命。

该技术增强的通讯特性反应在其协议名称上,HART ”H i g h w a y A d d r e s s a b l e R e m o t e T r a n s d u c e r ”(高速远程可寻址转换器)。

H A RT 协议智能仪表在不干扰4-20mA 模拟信号的同时允许双向数字通讯。

4-20mA 模拟和 HART 数字通讯信号能在一条线对上同时传递。

主要变量和控制信号信息由4-20mA 传送 (如果需要),而另外的测量、过程参数、设备组态、校准及诊断信息在同一线对、同一时刻通过HART 协议访问。

与其他过程仪表“开放”的数字通讯技术不同的是,HART 兼容现有系统。

hart,协议,如何实现模拟信号与数字信号的混合传输

竭诚为您提供优质文档/双击可除hart,协议,如何实现模拟信号与数字信号的混合传输篇一:haRt和4-20ma仪表输出信号为什么选择4-20ma电流的原因仪表输出信号为什么选择4-20ma电流的原因?变送器的传统输出直流电信号有0-5V、0-10V、1-5V、0-20ma、4-20ma 等,目前最广泛采用的是用4~20ma电流来传输模拟量。

工业上最广泛采用的是用4~20ma电流来传输模拟量。

采用电流信号的原因是不容易受干扰。

并且电流源内阻无穷大,导线电阻串联在回路中不影响精度,在普通双绞线上可以传输数百米。

上限取20ma是因为防爆的要求:20ma的电流通断引起的火花能量不足以引燃瓦斯。

下限没有取0ma的原因是为了能检测断线:正常工作时不会低于4ma,当传输线因故障断路,环路电流降为0。

常取2ma作为断线报警值。

电流型变送器将物理量转换成4~20ma电流输出,必然要有外电源为其供电。

最典型的是变送器需要两根电源线,加上两根电流输出线,总共要接4根线,称之为四线制变送器。

当然,电流输出可以与电源公用一根线(公用Vcc或者gnd),可节省一根线,称之为三线制变送器。

其实大家可能注意到,4-20ma电流本身就可以为变送器供电,如图1c所示。

变送器在电路中相当于一个特殊的负载,特殊之处在于变送器的耗电电流在4~20ma之间根据传感器输出而变化。

显示仪表只需要串在电路中即可。

这种变送器只需外接2根线,因而被称为两线制变送器。

工业电流环标准下限为4ma,因此只要在量程范围内,变送器至少有4ma供电。

这使得两线制传感器的设计成为可能。

在工业应用中,测量点一般在现场,而显示设备或者控制设备一般都在控制室或控制柜上。

两者之间距离可能数十至数百米。

按一百米距离计算,省去2根导线意味着成本降低近百元!因此在实际使用中两线制传感器得到越来越多的应用。

仪表输出信号为什么选择4-20ma电流的原因:远传信号用电流源优于电压源的原因:因为现场与控制室之间的距离较远,连接电线的电阻较大时,如果用电压源信号远传,由于电线电阻与接收仪表输入电阻的分压,将产生较大的误差,而用恒电流源信号作为远传,只要传送回路不出现分支,回路中的电流就不会随电线长短而改变,从而保证了传送的精度。

HART技术及原理

HART技术及原理

HART技术一、HART概述目前在世界各地所安装的大多数智能现场设备均具有HART功能。

但是,初次接触自动化领域的一些朋友可能需要重温这项强有力的技术。

简而言之,HART(高速可寻址远程传感器)协议是在智能设备与控制或监测系统之间的模拟线缆上发送和接收数字信息的全球标准。

更具体地说,HART是一个双向通信协议,提供智能现场仪表和主机系统之间的数据访问。

主机可以是任何软件应用程序,从技术人员的手持设备或笔记本电脑,到工厂中使用任何控制平台的过程控制、资产管理、安全或其他系统。

为现有工厂提供数字化升级HART技术为下述这些工厂的运营者提供了一项可靠的、长远的解决方案,他们努力寻求发挥拥有数字通信功能的智能设备的优势–该数字通信功能在大多数安装设备中都已存在。

然而在许多情况下,大多数应用程序无法为其现有的自动化系统加装能够接受HART协议所提供数字数据的系统。

由于目前运行的大多数自动化网络,均基于传统的4 - 20mA模拟线路,从而HART技术便可以发挥重要的作用,因为数字信息是与4 - 20mA信号同步通信的。

没有它,就不会有数字通信。

重要的、数字化作用当用于智能设备的调试投产和校准以及连续在线诊断时,HART技术易于使用且非常可靠。

有几个原因使得我们需要拥有可与智能设备通信的主机。

包括:∙设备的配置或重新配置∙设备诊断∙设备故障排除∙读取设备所提供的额外测量值∙设备状况和状态∙其它原因:使用HART技术拥有诸多好处,而且不断有更多的用户在他们的项目中报告其所带来的好处。

欲了解更多信息,请访问成功故事利用这些优势的成功经验解释了为什么HART技术能够成为所有通信协议中最大的协议,并安装于世界各地3千多万台设备之中。

如果您曾经使用座机电话,通过观察来电显示来了解打电话的是谁,您已经知道了HART协议所做的一半工作,即它告诉“谁”在打电话。

在工业自动化网络中,这个“谁”便是基于微处理器的智能现场设备。

除了让这种智能现场设备“给家打电话”之外,HART通信还让主机系统向智能仪表发送数据。

对于这篇文章,概述部分可以采用以下内容:概述Hart协议是一种常用于工业自动化领域的通信协议,它允许数字和模拟设备与监测和控制系统进行双向通信。

这种协议在工业过程控制领域有着广泛的应用,因为它可以实现高效、可靠的数据传输,并方便诊断和维护工业设备。

Wireless HART

Wireless HART的架构


公共密钥:被加入设备使用生成MAC层的MIC。 网络密钥:被所有网络设备共享,并且被网络中现有设备使 用来生成MAC层的MIC。 加入密钥:每个网络设备唯一,并在加入过程中由网络管理 器验证加入设备。 会话密钥:由网络管理器生成的在两个网络设备的端—端的 连接中是唯一的。提供了端-端的保密性和数据完整性。
Wireless HART的构建
通过改变TPM模块的内部分频器,我们可以改变 定时器的时钟频率 如下面公式:
ftimerclock = fbusclock / prescaler
预分频器设置为16。因此,每个定时器的精度 是1us,已经足够精确满足无线HART的MAC层的 需求 。

Wireless HART的构建
大部分状态机中的代码与一个执行的事务相关联。我们 在状态机中定义了六种状态:



加入:在这种状态下,设备尚未得到网络管理器的授权。当成功加入网 络后,它便进入空闲状态。 空闲:当设备成功加入网络,或者结束传递/接收数据包时,它进入这种 状态。 会话:当准备好发送数据包时,状态机进入此状态,并调用XMIT(发送) 引擎。 等待应答:当一个非广播的数据链路协议数据单元成功地传输,状态机 进入这种模式。 监听:此状态下,状态机调用RECV(接受)引擎等待即将传入的数据 链路协议数据单元。 应答:在此状态,状态机构造并发送一个与与之前监听状态接收到的 DLPDU相应的DLPDU。

计时器和定时器中断
无线HART对每个网络设备都有非常严格的时序要求。 一个10ms的时隙又进一步被划分成几个时间间隔。每个长 度从100us到4.5ms不等。 我们使用一个单独的16位TPM(定时器/脉宽调制模块) 模块来实现计时器。TPM模块的输入时钟被设置到总线时钟 (16MHz)。TPM模块包含一个自由运行计数器和一个比较 计数器。每当自由运行计数器等于比较计数器,一个定时器 中断就被触发 。

HART协议说明

HART协议说明

HART协议说明1 引言HART协议自1983年成为开放协议以来已经整整走过20年。

鉴于当时的技术状况,具备HART协议通讯能力的现场仪表(以下称HART仪表)比较昂贵,使用量不大。

另外,当时能够与HART仪表进行通讯的也只有手持器,能够与HART协议通讯配套的硬件和软件产品很少。

因此,用户中逐步形成了一种看法,似乎HART仪表中数字信号的作用仅仅只是进行零点、量程远方整定和故障诊断,其它没有什么用处。

经过近二十年的发展,HART协议已经成为过程自动化领域的一个事实上的标准。

现在支持HART协议的仪表制造商超过130家,其中45%在欧洲,43%在北美,12%在亚洲,是目前开放通讯协议中支持厂家最多的协议。

通过HART基金会认证的HART仪表品种已经达到近500种。

其中,压力仪表61种,温度仪表48种,流量仪表91种,物位仪表84种,分析仪表99种,执行器12种,阀门定位器33种。

同时,HART仪表的价格也大幅度地下降,在国内已经与模拟仪表的价格十分接近。

HART仪表已经不再是“奢侈品”。

支持HART仪表与上位计算机通讯的配套硬件和软件也十分丰富。

因此,现在可以在新的形势下重新评估一下HART协议数字信号的作用。

为此,HART协议基金会最近发动了一个活动,叫做“释放潜力”(Unleash the Power)。

借此引起用户们对HART协议的再次重视。

在当今现场总线技术已经十分火爆的时候,对HART协议的这种评估是否有实际意义呢?事实上,一项先进技术被用户接受是要相当长的时间的。

DCS系统从1975年问世到在中国普遍采用几乎花了15年的时间。

现场总线技术肯定比HART协议更加完整、更加先进、功能更加丰富,但是它的推广也同样需要时间。

而现在在HART仪表已经相当普及的情况下,用户只要花很少的投资,就可以享受到许多实实在在的好处。

我们为什么不去做呢?2 HART协议能够给用户带来什么好处每一个HART仪表的数字信号中平均能提供35~40项信息。

WirelessHart简介

WirelessHart简介

Wireless hart简介及与Zigbee的比较1无线HART 技术的基本特性无线技术的发展因为标准之争,至少延缓了两三年的时间。

而WirelessHART已经很明显地从标准之争中胜出。

2010年3月,WirelessHART通讯规范被国际电工标准委员会批准成为一个完整的国际标准(IEC 62591Ed.1.0),也是全球第一个获得这一级别国际认证的工业无线通讯技术。

” WirelessHART的成功源于广泛的用户基础,全球流程工业已经使用的HART设备超过了5000万台,可以说70%以上的现场设备都是通过HART连接的。

WirelessHART是HART的进一步延伸,能与原有仪表和控制系统完全兼容,只要是基于HART的设备、工具、培训、应用软件和工作流程都可继续保留使用。

这对保护用户的原有投资是非常重要的。

目前已经有上万台的WirelessHART设备在全球的过程工厂中应用。

WirelessHART是一种过程自动化应用领域的无线网状网络通信协议。

它给HART 协议增添了无线功能,同时保持了与现有HART设备、命令和工具的兼容性。

每个WirelessHART网络包括三个主要部分:l与过程或工厂设施连接的无线现场设备。

此设备可以是一台具有内置WirelessHART的设备;或者现有安装的拥有HART功能的设备,并且有一个WirelessHART适配器与之相连。

l网关使得这些设备能够与连接高速骨干网或其他现有工厂通信网络的主机应用程序通信。

l网络管理器负责配置网络、调度设备之间的通信、管理邮件路径以及监测网络的状态。

网络管理器可以集成到网关、主机应用程序或过程自动化控制器之中。

网络使用IEEE 802.15.4兼容无线信号,在2.4GHz工业、科学和医疗无线电频段工作。

无线信号采用直接序列展频技术和信道跳频以保证通信的安全性和可靠性,而且网络上设备之间使用TDMA同步、延时控制通信。

这项技术通过在范围广泛的过程控制行业,进行现场试验和实际的工厂安装,其成功已经被证明。

AMS Wireless Configurator组态软件的设置
双击点击想要组态的仪表位号,进行组态(以无线压力变送器为例)
AMS Wireless Configurator组态软件的设置
在路径System settings→Protocols→Protocols And Ports中可选择、设置通讯协议,选择会使用的通讯协议。点击Save Changes即可。
无线仪表操作说明
在路径System settings→Protocols→Modbus下可设置选择设备寄存位置和设备PV、QV、TV、SV、电池电压等。
在网关运行一段时间后,如果网关没有扫描的新的设备网关会自动把Active Advertising改为NO,此时网关扫描设备的周期会默认为半个小时,如果此时我们需要添加新设备,必须把Active Advertising重新改为YES,这样才能快速扫描到设备。(在设备突然断线时,也可使用此办法)
无线仪表操作说明
二、将智能预测技术扩展到之前因技术或经济原因无法使用的区域: 1.使任何 HART 设备具备无线功能,以获得新的测量点 2.使用高级仪表诊断功能 3.远程管理设备并监控设备运行状况 4.有效地从多变量设备收集数据 5.增强阀门的功能
无线仪表操作说明
1.无线网关设置 打开控制面板→网络和Internet→网络连接→本地连接内修改Internet 协议版本(TCP/IPV4)属性。更改IP地址(I)为192.168.1.20(不能与网关的IP地址相同),子网掩码(U)为255.255.255.0。如下图所示:
