HART协议简介及在智能电磁流量计中的应用
HART协议简介及在智能电磁流量计中的应用
1.引言HART，即Highway Addressable Remote Transducer，是可寻址远程传感器高速公路的简称，最早由美国Rosemount 公司开发并得到八十多家
著名仪表公司的支持,其特点是在不干扰4～20mA 模拟信号的同时允许双向数
字通讯。
符合HART 协议的智能电磁流量计不仅可以实现各种流量的检测和就地显示，还可以通过上位计进行远程设定，改变流量计的零点、量程，以及完成自诊断
等功能，在很大程度上方便了流量计的使用和维护，因而具有较强的市场竞争
力。
[1]本文讨论基于HART 协议智能电磁流量计具体实现的技术问题,一是要
解决硬件电路的设计问题，二是要讨论实现HART 协议命令集编程及上位机软
件的实现。
2 HART 协议简介
HART 协议遵循ISO 制订的OSI 开放式系统互连参考模型，采用了OSI
模型的第一层、第二层和第七层，即物理层、数据链路层和应用层。
2.1 物理层规范
HART 协议采用美国电话通讯系统Bell202 频移键控(FSK)标准，在4～20mA 的模拟±0.5mA 的正弦波，波特率是1200bps。
因为所叠加的正弦信号平均值为0，而且相位连续频移键控技术要求在波特率为1200Hz 的
数据位 1 和0 的边界的相位角是连续的，所以数字通讯信号不会影响
4～20mA 的模拟信号。
2.2 数据链路层规范[2][3]
这一部分协议规定了HART 帧的格式，实现建立、维护、数据链路通
讯功能，HART 协议根据冗余检错码信息，通过差错检测机制和采用自动重发。

罗斯蒙特质量流量计中国总代理(网址:)，德莱美（北京）国际贸易有限公司中国总代理(网址:)罗斯蒙特质量流量计工作特性及原理，罗斯蒙特质量流量计中国总代理，罗斯蒙特质量流量计广泛应用于石化等领域，是当今世界上最先进的流量测量仪表之一，在我厂主要产品如乙烯、丙烯和主要原料轻烃等的测量中使用可靠，精度高达1.7‰，为我厂的能源、物料的流量测量提高了准确度，避免了不必要的损失，创造了可观的经济效益。
质量流量测量原理一台质量流量计的计量系统包括一台传感器和一台用于信号处理的变送器。
Rosemount质量流量计依据牛顿第二定律：力=质量×加速度（F=ma）如图1所示，当质量为m的质点以速度V在对P轴作角速度ω旋转的管道内移动时，质点受两个分量的加速度及其力：（1）法向加速度，即向心加速度αr，其量值等于2ωr，朝向P轴；（2）切向角速度αt，即科里奥利加速度，其值等于2ωV，方向与αr垂直。
由于复合运动，在质点的αt方向上作用着科里奥利力Fc=2ωVm，管道对质点作用着一个反向力-Fc=-2ωVm。
当密度为ρ的流体在旋转管道中以恒定速度V流动时，任何一段长度Δx的管道将受到一个切向科里奥利力ΔFc：ΔFc=2ωVρAΔx （1）式中，A—管道的流通截面积。
由于存在关系式：mq=ρV A所以：ΔFc =2ωqmΔx （2）因此，直接或间接测量在旋转管中流动流体的科里奥利力就可以测得质量流量。
传感器内是U型流量管（图2），在没有流体流经流量管时，流量管由安装在流量管端部的电磁驱动线圈驱动，其振幅小于1mm，频率约为80Hz，流体流入流量管时被强制接受流量管的上下垂直运动。
在流量管向上振动的半个周期内，流体反抗管子向上运动而对流量管施加一个向下的力；反之，流出流量管的流体对流量管施加一个向上的力以反抗管子向下运动而使其垂直动量减少。
这便导致流量管产生扭曲，在振动的另外半个周期，流量管向下振动，扭曲方向则相反，这一扭曲现象被称之为科里奥利(Coriolis)现象，即科氏力。
Hart_Protocol
HART 协议1.HART 协议概况HART 协议是美国Rosemount 公司于1986年提出的一项标准通讯协议，其全称为Highway Addressable Remote Transducer，即可寻址远程传感器数据公路。
就现场总线的意义上说，HART 协议的特点是具有与现场总线类似的体系结构，具有总线式的数字通讯，但HART 并不是真正的现场总线，它只是现场总线的雏形，是从模拟控制系统向现场总线过渡的一块踏脚石。
所谓“过渡”，是指它在4~20mA模拟信号上叠加FSK（Frequency Shift Keying，频移键控，详见第二节）数字信号，既可进行4~20mA 模拟信号的传输，又能进行数字通讯，同时，数字通讯信号不影响模拟信号的传输。
显然，这是一项4~20mA模拟信号与数字通讯相兼容的标准。
作为一个开放性协议，经过十多年的发展，HART 协议已成为智能仪表事实上的工业标准。
HART 通讯协议参照“ISO/OSI”的模型标准，简化并引用其中的1，2，7三层制定而成，即：物理层，数据链路层和应用层，对应关系如下：2．HART 协议的物理层本节主要描述了HART 协议的物理层的信号模式和传输介质等，这些都是与OSI 协议参考模型的物理层的规定相一致的。
（1）FSK 频移键控HART 协议采用了Bell202 标准的FSK 频移键控信号。
它在4~20mA的模拟信号上叠加幅度为0.5mA的正弦调制波，1200Hz 代表逻辑“1”，2200Hz代表逻辑“0”，如下图所示。
由于所叠加的正弦信号平均值为0，所以不会影响4-20mA的输出电流。
因此，模拟仪表在数字通讯时仍可以照常工作，这是HART标准的重要优点之一。
二进制数据传送的速率为1200波特。
这就意味着“1”由1200Hz 的一个周期表示，而“0”大约由2200Hz 的两个周期表示。
信号频率和传送速率的选择依据美国Bell202标准，该标准用于在电话网上传送数字信息。
hart,协议,变量
竭诚为您提供优质文档/双击可除hart,协议,变量篇一：haRt协议简介haRt协议是由Rosemount（罗斯蒙特）公司提出的一种用于现场智能仪表和控制室设备之间的通信协议，它是4~20ma模拟信号向全数字信号过渡的一种协议，在4~20ma标准的模拟信号上叠加一个数字信号，原模拟信号仍然有效，且数字信号和模拟信号互不影响。
haRt协议的有线部分参照了iso的osi七层模型中的标准物理层、数据链路层和应用层这三层。
haRt协议有线部分的物理层规定了信号的传输方法和传输媒介，它采用基于bell202标准的频移键控技术(Fsk)来把数字信号叠加到4~20ma电流回路中。
它用1200hz的正弦波代表逻辑1，用2200hz的正弦波代表逻辑0，电流峰峰值为正负0.5ma。
如下图所示：+0.5ma0ma–0.5maa啊haRt协议有线部分的数据链路层规定了haRt有线协议帧的格式。
请求帧和响应帧格式如下所示：图1haRt帧格式haRt协议的应用层包括三个类别的haRt命令，用haRt 命令来操作数据，包括通用命令、常用命令和特殊命令，目前最新版本haRt协议的各类命令的命令号范围如下表所示：文章转载自沈阳中科博微自动化技术有限公司工业通讯大课堂篇二：haRt协议简介haRt转Rs-232串行口适配器haRt协议简介现代工业生产中存在着多种不同的主机和现场设备，要想很好地使用他们，完善的通讯协议是必须的。
haRt协议最初是由美国Rosemount公司开发，已应用了多年。
haRt协议使用Fsk技术，在4~20ma信号过程量上叠加一个频率信号，成功地把模拟信号和数字信号双向同时通讯，而不互相干扰。
haRt协议参照了国际标准化组织的开放性互连模型，使用osi标准的物理层、数据链路层、应用层。
haRt协议规定了传输的物理形式、消息结构、数据格式和一系列操作命令，是一种主从协议。
当通讯模式为“问答式”的时候，一个现场设备只做出被要求的应答。

2.2数据链路层
定义了一项主从协议 - 在正常使用下，现场设备只在收 到信号时才作回答。可以有两个主设备，例如，控制系统 作为第一主设备，而手持HART通信器作为第二主设备。时 序规则定义每个主设备可以开始通信事务的时间。单个多 点线缆对可以连接多达15个或更多的从设备。

物理层：HART协议的物理层规定了信号的传输方法、传输介质，HAR T支持模拟信号和数字信号在同一线路上传输。以贝尔202标准为基 础，采用频移键控（FSK），以1200bps的速率通信。代表0和1位值 的信号频率分别为2200和1200Hz。该低电平信号叠加在4到20mA的模 拟测量信号之上，而不会对模拟信号造成任何干扰。

1.简介
HART(Highway Addressable Remote Transduc er)，可寻址远程传感器高速通道的开放通信 协议，是美国ROSEMOUNT公司于1985年推出的 一种用于现场智能仪表和控制室设备之间的通 信协议。 HART装置提供具有相对低的带宽， 适度响应时间的通信，经过10多年的发展，HA RT技术在国外已经十分成熟，并已成为全球智 能仪表的工业标准。
3.2常用重要命令
（1）0号和11号命令用于识别现场设备。我们知道无论 采用长结构还是短结构都可以标识现场设备，应答0号命 令的信息中就包含了对不同设备的标识；然后，主机建 立不同的标志，为随后的长结构命令做准备。在HART4.0 版本及以前，传输类型码分为2字节:一个是生产厂商代 码，另一个是设备类型代码。而两个字节还可以节略。 到了HART5.0版本就必须使用充扩的代码表示设备信息， 还用ID号代替了最终流水线号。一个主机通常以0号命令 开始通讯，赋予随选地址0，然后扫描1～15地址，看谁 期待操作，显然由于HART5.0版本后的设备，主机可以使 用11号命令，再带一个全0的广播地址，外加命令中的标 志作为数据，等待着具有相同标志的从机响应，而应答 的11号命令等同于0号命令。

Refer to the Rosemount 248R Temperature TransmitterReference Manual for more instruction. The manual and this guide are alsoavailable electronically at /Rosemount.1.1Safety messagesWARNINGExplosionsExplosions could result in death or serious injury.Installation of device in an explosive environment must be in accordancewith appropriate local, national, and international standards, codes, andpractices.Review the Hazardous Locations Certifications for any restrictionsassociated with a safe installation.Process leaksProcess leaks could result in death or serious injury.Install and tighten thermowells and sensors before applying pressure.Do not remove the thermowell while in operation.Electrical shockElectrical shock could cause death or serious injury.Avoid contact with the leads and terminals. High voltage that may bepresent on leads can cause electrical shock.Unless marked, the conduit/cable entries in the housing use a ½–14 NPTthread form. Entries marked “M20” are M20 × 1.5 thread form. Ondevices with multiple conduit entries, all entries will have the samethread form. Only use plugs, adapters, glands, or conduit with acompatible thread form when closing these entries.When installing in a hazardous location, use only appropriately listed orEx certified plugs, glands, or adapters in cable/conduit entries.Quick Start Guide3Quick Start Guide June 2022 WARNINGPhysical accessUnauthorized personnel may potentially cause significant damage to and/ormisconfiguration of end users’ equipment.

(VR虚拟现实)HART协议
HART协议1、HART(Highway Addressable Remote Transducer)，可寻址远程传感器高速通道的开放通信协议，是美国ROSEMOUNT公司于1985年推出的一种用于现场智能仪表和控制室设备之间的通信协议。
HART装置提供具有相对低的带宽，适度响应时间的通信，经过10多年的发展，HART技术在国外已经十分成熟，并已成为全球智能仪表的工业标准。
HART协议采用基于Bell202标准的FSK频移键控信号，在低频的4-20mA 模拟信号上叠加幅度为0.5mA的音频数字信号进行双向数字通讯，数据传输率为1.2Mbps。
由于FSK信号的平均值为0，不影响传送给控制系统模拟信号的大小，保证了与现有模拟系统的兼容性。
在HART协议通信中主要的变量和控制信息由4-20mA传送，在需要的情况下，另外的测量、过程参数、设备组态、校准、诊断信息通过HART协议访问。
HART通信采用的是半双工的通信方式，其特点是在现有模拟信号传输线上实现数字信号通信，属于模拟系统向数字系统转变过程中过渡性产品，因而在当前的过渡时期具有较强的市场竞争能力，得到了较快发展。
HART 规定了一系列命令，按命令方式工作。
它有三类命令，第一类称为通用命令，这是所有设备都理解、都执行的命令；第二类称为一般行为命令，所提供的功能可以在许多现场设备（尽管不是全部）中实现，这类命令包括最常用的的现场设备的功能库；第三类称为特殊设备命令，以便于工作在某些设备中实现特殊功能，这类命令既可以在基金会中开放使用，又可以为开发此命令的公司所独有。
在一个现场设备中通常可发现同时存在这三类命令。
HART采用统一的设备描述语言DDL。
现场设备开发商采用这种标准语言来描述设备特性，由HART基金会负责登记管理这些设备描述并把它们编为设备描述字典，主设备运用DDL技术来理解这些设备的特性参数而不必为这些设备开发专用接口。
但由于这种模拟数字混合信号制，导致难以开发出一种能满足各公司要求的通信接口芯片。
