Description

一种核级安全显示装置及其组态-解析系统 技术领域
本发明涉及核安全级数字化仪控技术领域,具体涉及一种核级安全显示装置及其组态-解析系统。
背景技术
核级安全显示装置是一种应用于核电或核化工行业的、与安全级DCS配套的、用于为操作员提供参数监视和手动干预核电反应堆运行或核化工关键工艺过程功能的人机交互设备,同时也用于人员培训和操作考核。核级安全显示装置的基础功能包括组态、显示、通信、人机输入、存储和模拟仿真六个部分:
1)组态,通过组态工具离线设计工程页面、变量管理和参数配置;
2)显示,将工程页面以真实地或模拟的方式进行呈现;
3)通信,核级安全显示装置内部以及与安全级DCS之间的数据通信;
4)人机输入,允许手动输入控制指令以影响核级安全显示装置行为;
5)存储,对来自安全级DCS的工艺数据和自身状态信息的长周期记录;
6)模拟仿真,对核级安全显示装置工程组态页面的快速验证、运行过程数据的长周期记录、运行过程数据的加载回放等。
国内外核级安全显示装置组态功能设计一般采取将离线设计的人机交互工程页面、变量管理和参数配置转换为特定的计算机语言进而翻译为机器语言后在目标机上运行。这种方法中,工程组态信息翻译为目标代码的过程可信度计算是一个难题。通过形式化等数学方法可以进行翻译过程可信度验算,但这些方法较为复杂且工作耗时量巨大,验算通过后的结果也需要长时间的运行考证。
与此同时,国内外核级安全显示装置的运行环境一般为X86平台下的Linux环境或嵌入式环境。Linux环境下,各项应用开发容易但软件的确认验证工作复杂且困难,同时Linux环境下很难保证运行周期的稳定性,严重降低了核级安全显示装置的高确定性特征。嵌入式环境下,运行周期的稳定性能够较好保证,但各项应用功能开发相对复杂,同时由于嵌入式环境下处理器性能等制约因素,应用功能丰富程度不高,已不能满足日益增加的应用需求。
此外,国内外核级安全显示装置在设计模拟仿真功能时,采取了数值模拟的方式,仅实现行为模拟,无法通过模拟仿真功能对核级安全显示装置功能正确性和可靠性进行评估。
最后,国内外核级安全显示装置还存在着抗震特性不高、集成度低等不足,无法以一体化的解决方案同时兼顾工程应用、极高可靠性、培训教学、数字孪生、运行维护数据收集分析、预防性维修等发展性需求。
发明内容
为了解决现有技术存在的不足,本发明提供一种核级安全显示装置组态-解析系统以及基于该组态-解析系统设计的核级安全显示装置。
本发明的组态-解析系统不同于常规的图形组态方法即通过计算机语言翻译转换,而是采用了参数化的组态配置数据构造方法实现核级安全显示装置的工程组态编辑、编译,避免使用形式化等数学方法来验证翻译过程的可信度证明和验算活动巨大的工作量。
本发明基于组态配置数据构造方法设计的组态解析器、组态模拟器不同于多任务系统频繁的任务调度、堆栈操作、中断以及程序指针跳转,而是顺序的、单任务的执行工程组态相关功能,具有高确定性特征,即各功能项的执行顺序、执行时间以及执行结果是确定的且可预计。
本发明针对性设计了组态xml文件信息安全防范机制,即通过xml文件的加解密、CRC64校验等操作,有效防止非授权阅读、篡改xml文件现象的发生,从而消除了非法xml文件被编译导致实体机和模拟机运行异常的风险。
本发明核级安全显示装置的实体机和模拟机使用了相同的组态解析器,使得基础应用功能开发既可基于实体机也可基于模拟机,无本质上的区别。实体机和模拟机能够相互验证对方功能的正确性。
本发明通过实体机间的热备协同机制进一步提升了实体机的可靠性。该机制下主、备机权限自动生成,同时主机人机交互行为可在备机上同步复现,使得主、备机可部署在不同的物理空间而二者行为完全相同,提升了工程应用友好程度。
本发明采用数据差分存储与数据压缩存储结合的方法,解决了模拟机长周期运行过程数据存储的难题,为运行维护阶段实体机与模拟机长周期数字孪生奠定了基础。
本发明中的实体机和模拟机的仿真协同机制中,模拟机通过取得来自实体机故障自诊断数据和实体机转发的来自安全级DCS的网络变量数据,能够实时地对实体机进行数字孪生,即模拟机与实体机同步运行且运行行为一致。与此同时,模拟机能够对实体机进行故障诊断和预防性维修预警分析,避免了常规的数字孪生非实时性的缺点。此外,模拟机长周期记录的过程数据也有助于教学培训和事故后工况辅助分析和定位。
本发明中的实体机和模拟机均采用一体式抗震结构且外形相同,有利于安装使用和系统集成。

3、组态编译器
组态编译器遵照组态配置数据构造方法进行设计,将组态编辑器生成工程页面、变量等xml文件转换为组态配置数据,其执行过程中的显示窗如图10所示。
组态编译器执行期间,经过三个阶段处理生成组态配置数据,如图11所示。
图11中各阶段的功能和流程如下:
1)阶段1 ProjLoad
在本阶段,工程xml数据文件被装载到内存中,如图12所示。数据加载过程中同步进行xml数据文件的解密操作。
2)阶段2 CTCompile
在本阶段,将对“阶段1 ProjLoad”装载后的数据进行进一步的校验和检查,并根据组态配置数据构造方法约定的数据格式,将前述装载过程所得到的各类数据,转换成为可以保存在“组态配置数据”中的数据。本阶段的执行流程如图13所示。

4、组态解析器
组态解析器是根据组态配置数据构造方法设计的、可以部署在实体机或模拟机中、用于 组态配置数据解析的功能组件。组态解析器上电启动后的运行流程如图15所示。
组态解析器上电后,细分为2个过程:
1)初始化过程
上电后或维护模式转运行模式时执行初始化过程,进行硬件、配置等基础性初始化设置和工作模式判定。
2)执行过程
执行过程由维护模式和运行模式构成,这两种模式是互斥的,允许通过模式开关进行切换。具体地:
维护模式
维护模式提供简单的本地参数设置功能和组态配置数据下装,不进行模式转换时,是一个无限循环执行的功能。
运行模式
运行模式提供实体机和模拟机应用逻辑行为的控制调度,是一个无限循环功能。运行模式由开机初始态、页面准备态以及页面工作态三个阶段组成:
“开机初始态”执行组态页面配置初始化工作,执行结束无条件迁移至“页面准备态”。
“页面准备态”执行“将某页面切换成为当前页面”时的准备工作。执行完毕后无条件迁移到“页面工作态”。在“页面准备态”中,执行周期执行块、网络解包、配置数据载入、页面显示准备等工作,具体业务流程如图16所示。
“页面工作态”执行流程如图17所示。
无切换页面操作时,“页面工作态”无限循环运行直到切换页面操作发生并迁移到页面准备态。
无切换页面操作时,“页面工作态”周期性获取网络数据、人机输入,并将这些输入转换为数据存储、工程页面显示更新、网络数据输出等具体操作。
组态解析器对组态配置数据的解析流程如图18所示。
组态解析器按照图18所示流程,通过条件分支、周期循环、参数译码、参数传递等操作,实现对组态配置数据中的数据元素、功能Fun ID、功能Fun参数及调用关系的组合操作,最后由基础的功能Fun将工程组态页面显示及刷新、数据存取、逻辑控制、变量关联、网络变量收发等功能真实地、实时地还原。
5、组态模拟器
组态模拟器对组态编译器生成的组态配置数据进行解析并模拟运行。组态模拟器运行在普通个人计算机时,仅进行简单的工程组态页面验证;组态模拟器运行在特定的微型X86主 板且配套一体式抗震结构时,具备长时间记录模拟运行的过程数据的能力和实现对已模拟运行的历史过程进行重演的能力。由上述组态解析器与指令控制模块、数据管理模块、输入/输出缓冲区、网络变量xml解析模块和输入输出接口共同组成的组态模拟器整体架构如图19所示。其中,

数据管理模块提供长周期的组态解析器运行过程数据如人机输入、工程页面显示、趋势和故障日志、内存变量等数据的分区存储和管理,这些数据允许被重新加载到组态解析器中运行以再现历史运行过程。
4)网络变量xml解析
网络变量xml解析实现对组态编辑器生成的网络变量xml文件的解密并执行以下两种功能:将组态解析器产生的输出网络值以可视化列表呈现出来,实现输出网络变量监视功能;将输入网络变量以可视化列表呈现出来并允许输入,实现输入网络变量的模拟强制功能。
5)输入/输出缓冲区
输入缓冲区用于临时存储由数据管理模块合成的且能够被组态解析器理解的数据。输出缓冲区用于临时存储组态解析器周期性生成的过程或变量数据。
组态解析器产生的数据被细分为内部变量数据、工程页面数据以及人机操作。通过图20所示的差分存储方式实现对组态解析器周期性产生数据的长时间存储。
图20中,组态解析器产生的数据以15分钟为一个数据块,每个块包含了仿真时间戳、内部变量基础数据以及每分钟的变化数据、每分钟周期的工程页面数据、15分钟内每个运行周期捕获到的人机操作数据。
差分数据重新合成使用流程如下:
从某个15分钟时刻作为计算的起始点,通过该时刻的内部变量基础数据和每分钟的变化数据推算出某个具体地1分钟时刻内部变量的基础数据;
根据前一步推算出的某1分钟时刻的内部变量基础数据、工程页面数据以及逐周期记录的人机操作数据驱动组态模拟器进行历史运行过程的重演。
如图21所示,组态模拟器运行信息显示窗展示了组态模拟器运行过程中,对组态配置数据的解析运行详细过程信息,如页面编号、功能Fun、变量信息等。
如图22所示,组态模拟器运行视图展示了用于用于变量运行趋势监视的控件模拟。
组态模拟器具有工程组态页面验证和模拟机两种工作模式:
1)工程组态页面验证模式
本模式下,组态模拟器内部数据流向如图23所示。
本模式按以下流程执行:
“指令控制”发出“工程组态页面验证”工作指令;
“网络变量xml解析”将接收和发送网络变量列表以图形化的方式进行呈现,接收网络变量列表提供动态监视功能,发送网络变量列表提供模拟强制功能;
“输入输出接口”以软件和数据的形式模拟实体按键、电阻式触摸屏、网络通信以及数据存取访。
2)模拟机模式
本模式下,组态模拟器内部数据流向如图24所示。
本模式分为具有时间先后关系的模拟运行阶段和重演运行阶段。
a)模拟运行阶段
模拟运行时,组态模拟器与实体机具有相同的逻辑行为和时间特性,差异性体现在组态解析器周期性产生过程数据被送往输出缓冲区并存储。模拟运行阶段数据流如图25所示。
模拟运行时的流程为:
“指令控制”发出“模拟运行”工作指令;
“组态解析器”收到指令后,周期性解析并执行组态配置数据,其内存变量等过程数据周期性送往输出缓冲区存储;
“输入输出接口”收到指令后,读取一体式抗震结构人机输入和网络变量输入,并将网络变量送往组态解析器、人机输入送往组态解析器的同时送往“数据管理”,同时提供存储器访问模拟;
“数据管理”收到指令后,将人机输入和输出缓冲区数据周期性存储。
b)重演运行阶段
重演运行时,组态解析器重新加载模拟运行阶段存储的人机输入、内存变量等过程数据,实现对模拟运行阶段的历史过程、数据、操作的再现。重演运行阶段的数据流如图26所示。
重演运行时的具体流程为:
“指令控制”发出“重演运行”指令;
“数据管理”将存储的人机输入和内存变量等过程数据合成并周期性加载至在输入缓冲区;
“组态解析器”周期性载入输入缓冲区数据,并依赖这些数据实现对历史运行过程、状态、操作的重演。

通信协处理提供维护通信功能冷备用的维护通信链路管理,即通过参数设置可以选择光纤链路1、光纤链路2中的一条链路用于实体机与组态工具的维护通信;通信协处理提供隔离通信管理,通过RS485链路实现实体机与模拟机间的隔离通信。通信协处理提供热备通信链路管理,即通过两路光纤链路实现实体机与实体机间的热备通信。通信协处理提供安全通信链路管理,即通过两路热备冗余的光纤链路实现实体机与安全级DCS安全通信。
4、热备协同机制
热备协同机制由两台实体机通过热备通信、热备切换予以实现。实体机1、实体机2分别通过冗余的安全通信链路与安全级DCS连接;实体机1与实体机2通过热备通信链路连接,具体如图38所示。
图38中,实体机1或实体机2中的一台称为主机,另一台称为备机。主机和备机是一个相对概念,运行过程中主机和备机的工作权限允许切换。主、备机使用相同的硬件、软件、组态配置数据。
热备协同包括以下三个过程:
1)上电启动过程
上电启动过程中,通过先启动判定和实体机间故障互判定两种机制确定初始的主、备机权限,即先启动且无故障的实体机自动取得主机权限,具体过程如图39所示。
图39中,利用实体机1、实体机2上电启动时必然存在的时间差且该时间差大于诊断状态传输时间,结合实际诊断结果实现主、备机权限判定。以实体机1为例,说明主、备机权限确定判据:
实体机1自诊断结束时,自身状态正常且尚未收到实体机2的自诊断状态,实体机1取得主机权限;
实体机1自诊断结束时,自身状态正常且收到实体机2的自诊断状态为正常,此时根据时间戳判定实体机1是否取得主机权限,即自身时间戳小于对端,则取得主机权限,否则为备机权限;
实体机1自诊断结束时,自身状态正常且收到实体机2的自诊断状态为异常,实体机1取得主机权限;
实体机1自诊断结束时,自身状态异常,无论是否收到实体机2的自诊断状态,实体机1取得取得备机权限且报故障。
以上判据执行完毕后,仍有一定概率出现实体机1和实体机2均取得主机权限的可能。此时,设备ID号较大的实体机获得主机权限。
2)运行过程
运行过程包括实体机间的交互和实体机与安全级DCS间的交互两个部分。
实体机间的交互
主、备机权限确定后,运行过程中交互数据如图40所示。
主、备机周期性交换各自接收到的、来自安全级DCS的网络变量数据,用于自身的显示和存储。主、备机周期性交换自身的、输出到安全级DCS的网络变量数据。
主、备机周期性交换自身诊断状态,用于主、备切换。
主、备机周期性交换人机输入数据,用于自身的人机交互。
运行过程中,备机禁止响应自身的人机输入,使用主机发送的人机输入数据驱动页面切换、操作控制等行为,主机的工程页面显示、人机响应等行为会在备机同步复现,表现出“主机拖动备机运行”的效果。
主、备机与安全级DCS间的交互
运行过程中,主、备机与安全级DCS交换数据如图41所示。
主、备机均接受来自安全级DCS的网络变量,用于自身的显示和存储。
主、备机交换用于发送至安全级DCS的网络变量;主、备机送往安全级DCS的网络变量相同,且均由主机生成。
主、备机送往安全级DCS的网络变量末尾带主、从机数据标识,由安全级DCS选择性使用。
3)切换过程
当主机发生故障时,主、备机权限发生切换。切换过程中,主、备机之间、主、备机与安全级DCS交换数据的行为不受影响,具体过程如下:
探测到主机故障,进行权限切换时的确认;
确认备机具备升主机条件后,更新主、备机的数据标识;
备机使能自身人机输入、主机禁用自身人机输入;
切换结束。
当探测到主机故障,备机也故障时,整体报故障,不进行主备切换。
5、仿真协同机制
仿真协同机制由模拟机和实体机组成,以实现对实体机在运行维护阶段的数字孪生为目的,包括人机交互行为的同步复现、长周期过程数据记录与事故后工况分析、实体机故障自诊断数据监视与分析三种具体功能。以一台模拟机和一台实体机为例阐述仿真协同机制。
如图42所示,仿真协同机制下,实体机通过隔离通信链路与模拟机单向通信;实体机通过冗余的安全通信链路与安全级DCS双向通信。
如图43所示,实体机周期性将自身的人机输入数据和自诊断数据送往模拟机;实体机周期性将来自安全级DCS的网络变量数据送往模拟机。
仿真协同机制具备以下功能:
1)人机交互行为的同步复现
实体机与模拟机使用相同的组态配置数据时,实体机的人机输入数据和来自安全级DCS的网络变量被转发至模拟机。此时,模拟机通过禁用自身的人机输入并使用来自实体机的数 据,实时地将实体机上的人机交互如工程页面显示、人机响应等行为进行同步复现,表现出“实体机拖动模拟机运行”的效果。
2)长周期过程数据记录与事故后工况分析
结合模拟机海量数据存储能力和实施例1提出的组态模拟器的模拟机功能,模拟机与实体机同步运行且模拟机逐周期连续存储18个月的过程数据。
长周期过程数据记录的存储策略如图44所示。
长周期过程数据记录以实施例1提出的组态解析器生成数据的差分存储为基础进行设计,具体地:
以15分钟和1分钟数据的差分存储数据为基本数据单元;
在基本数据单元的基础上,构造出24小时内的基础数据的差分存储;
对24小时内的基础数据的差分存储进一步无损压缩。
数据调取使用时,逐级反向展开。
以上数据的使用方式如下:
A、培训教学
通过实施例1提出的模拟机“重演运行”的方式,为核电或核化工行业的操作和运维人员提供真实全面的关键工艺工程的状态监视和人机交互行为的重演回放。
B、事故后工况分析
基于模拟机硬件的计算和分析能力,通过调节其基准运行时钟定时器的方式,实现以1-10倍于实体机的运行速度,快速重演已获取到的过程数据记录,辅助事故后工况的快速分析和异常定位。
3)实体机故障自诊断数据监视与分析
实体机故障自诊断数据被送往模拟机进行分析和预防性维修判定,对以下几种典型的、反映实体机运行状态的数据进行监视和分析:
A、时钟相关的不稳定性分析
以下实体机数据被送往模拟机进行监视和分析:
每个周期的具体运行时间数值,以纳秒为单位;
周期内各数据块的具体运行时间数值,以纳秒为单位。

B、电源不稳定性分析

flash设备单个数据块单次写入数据前需要的重复擦除次数;
flash设备的单个数据块被重复擦除次数。
