背景技术Background technique
在本专利申请中,部分术语定义如下:In this patent application, some terms are defined as follows:
量值传递(Volume Value Transmission,简称量传):通过对计量器具的检定或者校准,将计量基准或计量标准所复现的单位量值,通过各等级的计量标准传递到工作计量器具的活动,以保证测量所得的量值准确一致。Volume Value Transmission (Volume Value Transmission, abbreviated as Volume Transmission): Through the verification or calibration of measuring instruments, the unit quantity value reproduced by the measuring standard or the measuring standard is transmitted to the working measuring instrument through the measuring standard of each level. To ensure that the measured value is accurate and consistent.
量值溯源(Quantity Value Traceability,简称溯源):通过一条具有规定不确定度的不间断的比较链,使测量结果或测量标准的值能够与规定的参考标准(通常是与国家计量基准或国际计量基准)联系起来的特性。Quantity Value Traceability (Traceability for short): Through an uninterrupted comparison chain with a specified uncertainty, the value of a measurement result or measurement standard can be compared with a specified reference standard (usually with a national measurement standard or an international measurement standard). Benchmark).
量传与溯源互为逆过程:量传是自上而下地将国家计量基准器具所复现的量值逐级传递给各级计量标准器具直至工作计量器具的过程;而溯源则是自下而上地将工作计量器具或计量标准器具的测量值溯源至上级计量标准器具直至国家计量基准器具的过程,且可越级进行。Quantitative transmission and traceability are the inverse process of each other: Quantitative transmission is the process of transferring the value reproduced by the national measurement standard instrument to various levels of measurement standard instruments from top to bottom to the working measurement instrument; while traceability is from bottom to bottom. Shangdi traces the measured value of the working measuring instrument or measuring standard instrument to the superior measuring standard instrument to the national standard measuring instrument, and it can be carried out by skipping the level.
检定(Verification):查明和确认计量器具是否符合法定要求的活动,它包括检查、加标记和(或)出具检定证书等。只有符合要求的计量器具才为其出具检定证书和(或)加标记,也即赋予了该计量器具的法制特性,不符合要求的计量器具只能出具检定结果通知书。检定是量传的重要手段,包括首次检定、后续检定等。Verification: The activity to find out and confirm whether a measuring instrument meets statutory requirements. It includes inspection, marking and/or issuance of a verification certificate. Only the measuring instruments that meet the requirements will be issued with a verification certificate and/or marked, which means that the legal characteristics of the measuring instrument are given, and the measuring instruments that do not meet the requirements can only be issued with a verification result notification. Verification is an important means of mass transmission, including the first verification and subsequent verification.
首次检定(First Verification):计量器具生产出来以后使用之前,对其按检定规程的要求进行的一系列检查、加标记和(或)出具检定证书等操作。其目的是为了确定新生产或新购买的计量器具的计量性能是否符合型式批准时规定的要求。First Verification: A series of inspections, markings and/or issuance of verification certificates for measuring instruments before they are used after they are produced. Its purpose is to determine whether the measurement performance of newly produced or newly purchased measuring instruments meets the requirements specified in the type approval.
后续检定(Follow-up Verification):计量器具首次检定后的任何一种检 定,如强制性周期检定(简称“强检”)、有效期内的周期检定、修理后检定等。不论它是由用户提出请求还是由于某种原因使有效期内的封印失效而进行的检定均为后续检定。Follow-up Verification: Any type of verification after the first verification of a measuring instrument, such as mandatory periodic verification (referred to as "strong verification"), periodic verification within the validity period, and post-repair verification. Regardless of whether it is requested by the user or due to some reason, the verification performed by the seal within the validity period is a follow-up verification.
检验(Test):查明计量器具的检定标记或检定证书是否有效,保护标记是否损坏,检定后计量器具是否遭到明显改动,以及其误差是否超过使用中最大允许误差所进行的一种检查叫(使用中)检验。其主要是查明计量器具是否超差。Test: Check whether the verification mark or verification certificate of the measuring instrument is valid, whether the protection mark is damaged, whether the measuring instrument has been significantly changed after verification, and whether the error exceeds the maximum allowable error in use. A kind of inspection is called (In use) Inspection. Its main purpose is to find out whether the measuring instruments are out of tolerance.
强制检定(Compulsory Verification)(即“强制性周期检定”,简称“强检”):对社会公用计量标准器具,部门和企事业单位使用的最高计量标准器具,以及用于贸易结算、安全防护、医疗卫生、环境监测等四个方面的列入国家强检目录的工作计量器具,由县级以上人民政府计量行政部门指定的法定计量检定机构或授权计量技术机构,实行定点、定期的检定。“定点”是指实行“属地管理”,即行政区划上属于某区域的企事业单位的计量器具必须送到其区域内政府法定的计量检定机构或授权计量技术机构检定。“定期”是指计量器具的检定周期(或“有效检定时间间隔”)必须等于或小于国家颁布的计量检定规程中所规定的检定周期(或“有效检定时间间隔”)。Compulsory Verification (ie "Compulsory Verification", referred to as "Compulsory Verification"): For social public measurement standard equipment, the highest measurement standard equipment used by departments, enterprises and institutions, as well as for trade settlement, safety protection, Medical and health, environmental monitoring and other four aspects of work measurement instruments listed in the national compulsory inspection catalog, the statutory measurement verification agency or authorized measurement technology agency designated by the measurement administrative department of the people's government at or above the county level, implement fixed-point and regular verification. "Designated" refers to the implementation of "territorial management", that is, the measuring instruments of enterprises and public institutions belonging to a certain area in the administrative division must be sent to the government's statutory measurement verification agency or authorized measurement technology agency in the area for verification. "Periodic" means that the verification period (or "effective verification time interval") of measuring instruments must be equal to or less than the verification period (or "effective verification time interval") stipulated in the national metrological verification regulations.
首次强检(First Compulsory Verification):住宅建设中安装使用的电能表、水表、燃气表、热量表等工作计量器具,简称“民用四表”,在安装使用前必须实行首次强制检定,但由于其量大面广、装拆不便,实行首次强检后,不再进行后续检定,而是规定一定的使用期限,到期报废,相应安装位置用新的同类型计量器具取代。这种情况简称“首次强检,到期轮换”。First Compulsory Verification: Work measuring instruments such as electric energy meters, water meters, gas meters, and heat meters installed and used in residential construction, referred to as "civil four meters", must be first compulsory verification before installation and use, but due to their Large quantity and wide area, inconvenient assembly and disassembly, after the first mandatory inspection, no follow-up verification will be carried out, but a certain period of use will be stipulated, and the corresponding installation position will be replaced with a new measuring instrument of the same type. This situation is referred to as "first compulsory inspection, due rotation".
非强制检定(Non-mandatory Verification):由计量器具使用单位自己或委托具有社会公用计量标准或授权的计量检定机构,依法进行的一种检定。非强制检定计量器具的检定周期和检定方式由企业依法自行管理:检定周期或送检单位均由企业根据计量器具的实际使用情况,本着科学、经济和量值准确的原则自主确定。Non-mandatory verification (Non-mandatory Verification): a type of verification carried out in accordance with the law by the unit using the measuring instrument itself or entrusted by a measurement verification agency with social public measurement standards or authorization. The verification cycle and verification methods of non-compulsory verification measuring instruments are managed by the enterprise itself according to law: the verification period or the inspection unit is determined by the enterprise based on the actual use of the measuring instruments, based on the principles of science, economy and accuracy.
校准(标定)(Calibration):是溯源的主要手段,是在规定条件下的一组操作:先确定由测量标准所提供的量值与相应示值之间的关系,再用此信息确定由示值获得测量结果的关系,这里测量标准提供的量值与相应示值均具有测量不确定度。Calibration (Calibration): It is the main method of traceability. It is a set of operations under specified conditions: first determine the relationship between the value provided by the measurement standard and the corresponding indication, and then use this information to determine the indication The relationship between the measured value and the measurement result, where the measured value provided by the measurement standard and the corresponding displayed value have measurement uncertainty.
比对(Comparison):即比较、核对的意思,是指在规定条件下,对相同准确度等级或不确定度范围的同种计量器具复现的量值之间进行比较的过程。如果比对所用样品的量值或技术参数,比对参与者事先不知情,则我们称此种比对为盲样比对。计量器具的比对通常既包括实验室或拥有同类计量器具的企事 业单位之间的方法比对、人员比对、设备比对、环境条件比对,也包括实验室或拥有同类计量器具的企事业单位内部的方法比对、人员比对、设备比对、环境条件比对等。Comparison (Comparison): the meaning of comparison and verification, which refers to the process of comparing the recurring values of the same measuring instruments with the same accuracy level or uncertainty range under specified conditions. If the amount or technical parameters of the samples used for comparison are not known to the participants in advance, we call this comparison a blind sample comparison. The comparison of measuring instruments usually includes method comparison, personnel comparison, equipment comparison, and environmental condition comparison between laboratories or enterprises and institutions with similar measuring instruments, as well as laboratories or enterprises with similar measuring instruments. Internal method comparison, personnel comparison, equipment comparison, environmental condition comparison, etc. within the institution.
测试(测量)(Test):测量、试验的意思,是具有试验性质的测量,是测量和试验的综合。由于测试和测量密切相关,在实际使用中往往并不严格区分测试与测量。测试的基本任务就是借助专门的计量器具、设计合理的实验方法、进行必要的信号分析与数据处理,从而获得被测对象诸如性能和精度等有关信息。测试可以执行国家计量检定规程或校准规范中相应条款,也可以根据被测对象的性能和精度要求采用委托方与被委托方双方认可的技术依据进行。Test (Measurement) (Test): The meaning of measurement and experiment is a measurement with experimental nature, which is a combination of measurement and experiment. Since test and measurement are closely related, it is often not strictly distinguished between test and measurement in actual use. The basic task of testing is to use special measuring instruments, reasonably designed experimental methods, and necessary signal analysis and data processing to obtain relevant information such as performance and accuracy of the measured object. The test can be carried out in accordance with the corresponding provisions in the national metrological verification regulations or calibration specifications, or can be carried out according to the performance and accuracy requirements of the tested object using the technical basis recognized by both the client and the client.
期间核查(Intermediate Checks)[运行检查(Run check)]:为保持对计量器具检定/校准状态的可信度,在其两次检定/校准之间对其进行的核查,包括使用中的计量器具的期间核查和参考标准器的期间核查,二者合起来本质上相当于ISO/IEC导则25中的运行检查。这种核查应按规定的程序进行。通过期间核查可以增强实验室的信心,保证检测数据的准确可靠。Intermediate Checks [Run check]: In order to maintain the credibility of the verification/calibration status of measuring instruments, the verifications performed between two verifications/calibrations, including measuring instruments in use The period check of the reference standard device and the period check of the reference standard, the two together are essentially equivalent to the operation check in ISO/IEC Guide 25. Such verification shall be carried out in accordance with prescribed procedures. Passing the verification during the period can enhance the confidence of the laboratory and ensure the accuracy and reliability of the test data.
计量器具(Measuring Instruments):实施检定或校准的主要工具,泛指那些能单独或连同辅助设备一起,用以直接或间接测出被测对象量值的计量装置(如出租汽车计价器检定装置、高频微波功率计校准装置等)、仪器仪表(如心/脑电图机、压力表、流量计等)、传感器(各类计量装置或仪器仪表所配传感器、各类独立输入/输出的传感器、各类设备中组成负反馈闭环控制回路中的测量传感器或测量探头等)、量具(如量块、砝码等)和用于统一量值的标准物质(如一氧化碳气体标准物质、紫外光区透射比标准滤光片)等。根据国家《计量法》和计量器具相关管理条例的规定,计量器具在使用之前或在其有效检定周期或校准时间间隔内,必须由具有相关资质的计量技术机构按照相应的计量检定规程或校准规范的规定对其进行“检定”或“校准”。同时,在计量器具有效检定周期内,计量器具使用部门也可按照相应的计量检定规程或校准规范的规定,对计量器具进行使用中检验。Measuring Instruments (Measuring Instruments): The main tools for performing verification or calibration, generally refer to those measuring devices that can directly or indirectly measure the value of the measured object (such as taxi meter verification device, High-frequency microwave power meter calibration device, etc.), instrumentation (such as heart / EEG machine, pressure gauge, flowmeter, etc.), sensors (various measuring devices or sensors equipped with instrumentation, various independent input/output sensors , Various types of equipment constitute a negative feedback closed-loop control loop of measuring sensors or measuring probes, etc.), measuring tools (such as gauge blocks, weights, etc.), and standard materials for uniform measurement (such as carbon monoxide gas standard materials, ultraviolet light zone) Standard transmittance filter) etc. According to the national "Measuring Law" and the relevant regulations of measuring instruments, measuring instruments must be used by a qualified metrological technical institution in accordance with the corresponding metrological verification procedures or calibration specifications before they are used or within their effective verification period or calibration interval. It is “verified” or “calibrated” according to the regulations. At the same time, within the effective verification period of the measuring instrument, the user department of the measuring instrument can also perform the in-use inspection of the measuring instrument in accordance with the provisions of the corresponding measurement verification regulations or calibration specifications.
按计量学用途分类,计量器具主要包括计量基准器具、计量标准器具、工作计量器具等三类计量器具。其中:According to the classification of metrological purposes, measuring instruments mainly include three types of measuring instruments: standard measuring instruments, standard measuring instruments, and working measuring instruments. among them:
1)、计量基准器具(Measurement Base Instruments)(或称“基准计量器具”):在某个特定领域内,具有当代最高准确度等级的计量器具,既是量传的起点也是溯源的终点。经国际协议公认,在国际上作为给定量的其它所有标准定值依据的标准称为国际基准;经国家正式确认,在国内作为给定量的其它所有标准定值依据的标准称为国家基准。国家计量基准器具包括国家计量基准(主基准) 计量器具、国家副计量基准计量器具和国家工作基准计量器具三类。国家计量基准是一个国家量传的起点,也是一个国家溯源的终点,具有国内最高的计量学特性;国家的副计量基准用以代替国家计量基准的日常使用和验证国家计量基准的变化,一旦国家计量基准损坏,国家副计量基准可用来代替国家计量基准;国家工作计量基准主要是用以代替国家副计量基准的日常使用,检定/校准计量标准,以避免由于国家副计量基准频繁使用而丧失其应有的计量学特性或遭损坏。1) Measurement Base Instruments (or "benchmark measuring instruments"): In a certain field, the measuring instruments with the highest level of accuracy in the present age are both the starting point of measurement and the end of traceability. Recognized by international agreements, the standard that is used as the basis for the value of all other standards for a given amount in the world is called the international benchmark; after officially confirmed by the country, the standard that is the basis for all other standards for a given amount in the country is called the national benchmark. National benchmarking instruments include three categories: national benchmark (main benchmark) measuring instruments, national secondary benchmark measuring instruments and national working benchmark measuring instruments. The national measurement standard is the starting point of a national measurement and the end point of a national traceability. It has the highest domestic measurement characteristics; the national secondary measurement standard is used to replace the daily use of the national measurement standard and verify the change of the national measurement standard. If the measurement datum is damaged, the national secondary measurement datum can be used to replace the national measurement datum; the national working measurement datum is mainly used to replace the daily use of the national secondary measurement datum, and verify/calibrate the measurement standard to avoid losing it due to the frequent use of the national secondary measurement datum. The due metrological characteristics may be damaged.
2)、工作计量器具(Work Measuring Apparatus)(或称“工作用计量器具”、“普通计量器具”):一般日常工作中或产(商)品生产线上所用的计量器具(含生产现场所用的各类传感器等)。其准确度等级最低,既是量传的终点也是溯源的起点。本专利将具有负反馈自动控制功能的设备中的测量传感器也归于工作计量器具类。2) Work Measuring Apparatus (or “Working Measuring Apparatus”, “Ordinary Measuring Apparatus”): Measuring instruments used in general daily work or production (commercial) production lines (including those used at the production site) Various sensors, etc.). It has the lowest level of accuracy, which is both the end point of mass transmission and the starting point of traceability. This patent also classifies measuring sensors in equipment with negative feedback automatic control functions into the category of working measuring instruments.
3)、计量标准器具(Standards of Measurement)(或称“标准计量器具”):准确度等级介于计量基准器具和工作计量器具之间、处于量传或溯源中间的计量器具,既承接计量基准器具的量传并向下量传至工作计量器具,也接受工作计量器具的溯源并最终由其溯源至计量基准器具。3) Standards of Measurement (or "standard measuring instruments"): measuring instruments whose accuracy level is between the measurement reference instruments and the working measurement instruments, and are in the middle of quantity transmission or traceability, which not only undertakes the measurement standards The quantity of the instrument is transmitted and passed down to the working measuring instrument, and the traceability of the working measuring instrument is also accepted and finally traceable to the measuring standard instrument.
计量器具按其输出或输入方式分为两类:标准源(Standard Source)类或标准表(Standard Instrument)类。其量传或溯源的技术参量也有两种表现形式:或者是作为标准源的输出(Output)量,或者是作为被标准表测量的输入(Input)量:Measuring instruments are divided into two categories according to their output or input methods: Standard Source or Standard Instrument. The technical parameters of its quantity transmission or traceability also have two manifestations: either as an output quantity as a standard source, or as an input quantity measured by a standard meter:
1)、计量装置或计量仪器(Metrological Device or Instrument):参与量传或溯源的技术参量或者作为标准源类输出给被检校表而检定/校准被检校表的示值误差,或者作为标准表类去检定/校准输入至其输入口的被测源的示值误差,如美国FLUKE 5500A多功能校准器是源,而丹麦B&K公司3560型PULSE多分析仪系统是表也是源;1) Metrological Device or Instrument (Metrological Device or Instrument): technical parameters involved in measurement transmission or traceability, or output as standard source to the calibrated meter to verify/calibrate the displayed value error of the calibrated meter, or as a standard The meter class verifies/calibrates the indication error of the measured source input to its input port. For example, the United States FLUKE 5500A multi-function calibrator is the source, while the Danish B&K 3560 PULSE multi-analyzer system is the meter and the source;
2)、计量仪表(Measurement Apparatus):一般属于表类,如压力表、温度表等;2) Measurement Apparatus: generally belong to the meter category, such as pressure gauges, temperature gauges, etc.;
3)、传感器(Sensor or Transducer):传感器的输入端一般归于表类,例如各类计量装置或仪器仪表所配传感器的输入端、各类独立的传感器的输入端等,传感器的输出端一般归于源类(各类计量装置或仪器仪表所配传感器的输出端、各类独立的传感器的输出端等);3) Sensor (Sensor or Transducer): The input end of the sensor is generally classified as a meter, such as the input end of various measuring devices or instruments equipped with sensors, the input end of various independent sensors, etc. The output end of the sensor is generally classified into Sources (the output terminals of various measuring devices or sensors, the output terminals of various independent sensors, etc.);
4)、量具(Measuring Tool):既可以是源类也可以是表类,如量块是源而卡尺是表;4) Measuring Tool: It can be either a source type or a table type. For example, the gauge block is the source and the caliper is the table;
5)、标准物质(Standard Substances):一般属于源类,如标准pH溶液等。5) Standard Substances: generally belong to the source category, such as standard pH solutions.
目前,“量传”或“溯源”的方式主要有以下四种:At present, there are mainly four methods of "quantity transmission" or "tracing to the source":
一、用实物标准进行逐级量传或溯源1. Use physical standards for step-by-step measurement or traceability
这是一种传统的量传或溯源方式,也是目前我国在长度、温度、力学、电学等计量领域常用的一种量传或溯源方式,由计量检定/校准机构或授权有关部门或企事业单位的计量技术机构(以下简称“上级计量检定/校准机构”)实施,属于“检定”的出具“检定证书”或“结果通知书”,属于“校准”的出具“校准证书”并给出“测量结果的不确定度评定”,其基本步骤为:This is a traditional measurement transmission or traceability method, and it is also a measurement transmission or traceability method commonly used in the measurement fields of length, temperature, mechanics, electricity, etc. in our country. The measurement verification/calibration agency or authorized departments or enterprises and institutions are used The measurement technology institution (hereinafter referred to as the "superior measurement verification/calibration institution") implements the implementation of the "verification certificate" or "result notification" for the "verification", and the "calibration certificate" for the "calibration" and gives "measurement" Evaluation of Uncertainty of Results", the basic steps are:
1)、需量传/溯源的待检单位将其待检的计量器具(一般为“计量标准器具”或“工作计量器具”),采用人工搬运的方式,定期送至上级计量检定/校准机构进行检定/校准,对不便于拆卸或搬运的计量器具,则请上级计量检定/校准机构技术人员上门到该需量传/溯源机构现场进行检定/校准。1) The unit to be inspected for demand transmission/traceability sends its measurement instruments to be inspected (usually "standard measuring instruments" or "working measuring instruments") by manual handling and regularly sent to the higher-level measurement verification/calibration institution For verification/calibration, for measuring instruments that are not easy to disassemble or transport, please ask the technicians of the higher-level metrological verification/calibration institution to come to the site of the demand transmission/traceability institution for verification/calibration.
2)、上级计量检定/校准机构技术人员依照国家计量检定系统表、计量检定规程或校准规范对需量传/溯源单位的计量器具进行检定/校准。属于检定且检定结果合格的出具检定证书、检定结果不合格的出具检定结果通知书,属于校准的,出具“校准证书”并给出“测量结果的不确定度评定”。2) The technical personnel of the superior metrological verification/calibration institution shall verify/calibrate the measuring instruments of the required quantity transmission/traceability unit in accordance with the national metrological verification system table, metrological verification regulations or calibration specifications. A verification certificate is issued if the verification result is qualified, and a verification result notification is issued if the verification result is unqualified. If it is a calibration, a "calibration certificate" is issued and an "Uncertainty Evaluation of Measurement Results" is issued.
3)、需量传单位接到检定证书、并具有计量标准考核合格证时,才能进行量值传递或直接使用此计量器具进行测量;需量传单位接到检定结果通知时,可对被检(校)计量器具进行降级使用或报废处理。需溯源单位接到校准证书后,根据校准结果和测量不确定度评定数据,确定被校准计量器具是否符合自身开展工作需要。3). When the demand transfer unit receives the verification certificate and has the measurement standard assessment certificate, it can transfer the value or directly use this measuring instrument for measurement; when the demand transfer unit receives the notification of the verification result, it can (School) Measuring instruments are degraded for use or scrapped. After receiving the calibration certificate, the traceable unit determines whether the calibrated measuring instrument meets the needs of its own work according to the calibration result and measurement uncertainty evaluation data.
二、用发放标准物质(CRM)进行量传或溯源2. Use the issued standard material (CRM) for quantity transmission or traceability
标准物质就是在规定条件下具有高稳定的物理、化学或计量学特征,并经正式批准作为标准使用的物质或材料。它在计量领域的作用主要体现在以下几个方面:A standard substance is a substance or material that has highly stable physical, chemical or metrological characteristics under specified conditions and is officially approved for use as a standard. Its role in the field of measurement is mainly reflected in the following aspects:
1)、作为“控制物质”与被测试样同时进行分析质量。1) As a "control substance", analyze the quality at the same time as the tested sample.
2)、作为“标准物质”对新的测量方法和仪器的准确度和可靠性进行评价。2) As a "standard material", evaluate the accuracy and reliability of new measurement methods and instruments.
3)、作为“已知物质”对新的测量方法和仪器的准确度和可靠性进行评价。3) Evaluate the accuracy and reliability of new measurement methods and instruments as "known substances".
标准物质一般分为一级标准物质和二级标准物质。一级标准物质主要用于标定二级标准物质或检定/校准高精度计量器具,二级标准物质主要用于检定/校准一般计量器具。Standard materials are generally divided into primary and secondary standard materials. The primary reference materials are mainly used to calibrate secondary reference materials or to verify/calibrate high-precision measuring instruments, and the secondary reference materials are mainly used to verify/calibrate general measuring instruments.
这种量传或溯源方式是:由国家授权一些有能力的企事业单位生产检定/校准某些计量器具的标准物质,当需量传/溯源的单位有相应计量器具需要检定/ 校准时,需量传/溯源的单位将其待检计量器具送至上级计量检定/校准机构、或者邀请上级计量检定/校准机构的技术人员到自身现场,选用相应的标准物质来对待检计量器具进行检定/校准。This method of quantity transmission or traceability is: the state authorizes some capable enterprises and institutions to produce standard materials for verification/calibration of certain measuring instruments. When the unit that needs quantity transmission/traceability has corresponding measuring instruments that need verification/calibration, The unit of measurement transmission/traceability sends its measurement instruments to be inspected to the higher-level measurement verification/calibration institution, or invites technicians from the higher-level measurement verification/calibration institution to its own site, and selects the corresponding standard materials to verify/calibrate the measurement instruments to be inspected .
企事业单位或计量检定/校准技术机构均可根据量传或溯源的实际需要购买相应标准物质,作为“计量标准”用于检定/校准某些计量器具或评价计量方法,检定合格或校准符合要求的计量器具才能使用。这种方式目前主要应用于理化计量领域。Enterprises and institutions or metrology verification/calibration technical institutions can purchase corresponding reference materials according to the actual needs of measurement transmission or traceability, which can be used as "metric standards" to verify/calibrate certain measuring instruments or evaluate measurement methods. The verification is qualified or the calibration meets the requirements The measuring instruments can be used. This method is currently mainly used in the field of physical and chemical measurement.
这种方式在操作上与第一种方式差别不大,均是由人工(手工)的方式进行操作,只是用“标准物质”代替了第一种方法中所用的“计量标准器具”而已。This method is not much different from the first method in operation. It is operated manually (manually), except that the "standard material" used in the first method is replaced with the "standard measuring instrument" used in the first method.
三、用发播标准信号进行量传或溯源3. Use standard signals to transmit or trace the source
通过无线电台发播标准信号进行量传或溯源。目前,在我国,该方法主要用于时频或某些无线电计量领域。用户可现场直接接收标准信号并检定/校准相应时频或某些无线电计量器具。国家授权某些计量技术机构发播标准时间、频率或标准(电视)格式信号,需量传/溯源单位的待检计量器具若“预先”处于开机或接收状态时,待检计量器具捕捉并接收到欲接收的标准信号后,据相应检定规程或校准规范,对所接收到的标准信号进行“检定/校准”并产生相应“检定/校准”数据。需量传/溯源单位将该数据回传至上级计量检定/校准机构,上级计量检定/校准机构对该数据进行分析处理,求出被检校计量器具的检定误差/校准结果、系统误差与测量随机误差、测量结果的不确定度等,并出具检定证书(结果通知书)或校准证书。Broadcast standard signals through radio stations for quantitative transmission or traceability. At present, in my country, this method is mainly used in time-frequency or certain radio measurement fields. Users can directly receive standard signals on site and verify/calibrate corresponding time-frequency or certain radio measuring instruments. The state authorizes certain measurement technology institutions to broadcast standard time, frequency or standard (television) format signals. If the measurement instrument to be inspected in the unit of measurement transmission/traceability is "previously" turned on or received, the measurement instrument to be inspected will be captured and received After the standard signal to be received is received, the received standard signal is "verified/calibrated" and the corresponding "verified/calibrated" data is generated according to the corresponding verification regulations or calibration specifications. The demand transmission/traceability unit transmits the data back to the superior metrological verification/calibration agency, and the superior metrological verification/calibration agency analyzes and processes the data to obtain the verification error/calibration result, system error and measurement of the metrological instrument being calibrated Random error, uncertainty of measurement results, etc., and issue a verification certificate (result notice) or calibration certificate.
四、用“测量保证程序制”(MAPS)进行量传或溯源4. Use the "Measurement Assurance Program System" (MAPS) for mass transfer or traceability
美国国家标准局制订了一种“测量保证程序制(MAPS)”的量传或溯源新方案。具体方案虽因参数不同而异,但大体如下:由国家标准局制作一批一定准确度的“传递标准”(例如10个功率座),每年发两个给各下级实验室,同时规定测量方法。各下级实验室用自己的工作标准测量收到的“传递标准”,然后将测量结果连同“传递标准”一起寄回国家标准局。经数据处理后,国家标准局告知下级实验室的系统误差与测量误差等。下一年,由国家标准局另换两个“传递标准”给该实验室,重复前一年的操作过程。MAPS采用了闭环量传或溯源方式,在量传过程中,不但考核了下级实验室计量器具所能达到的测量准确度,而且考核了下级测量人员的技术水平和实验室工作现场条件引入的误差等。在我国,这种方式也在一些特定的现场检定、校准、测试领域有所应用,但“传递标准”不易获得,且重复劳动、费工又费时,因此,并没有大范围推广。The American National Bureau of Standards has developed a new program of "Measurement Assurance Program System (MAPS)" for quantity transmission or traceability. Although the specific scheme varies with different parameters, it is roughly as follows: The National Bureau of Standards produces a batch of "transfer standards" with a certain degree of accuracy (for example, 10 power sockets), and sends two to each lower-level laboratory every year, and specifies the measurement method. . Each lower-level laboratory measures the received "transfer standard" with its own working standards, and then sends the measurement results back to the National Bureau of Standards along with the "transfer standard". After data processing, the National Bureau of Standards informs the lower-level laboratories of the system errors and measurement errors. In the next year, the National Bureau of Standards will exchange another two "transfer standards" to the laboratory and repeat the operation process of the previous year. MAPS adopts a closed-loop measurement transmission or traceability method. In the measurement transmission process, it not only evaluates the measurement accuracy that can be achieved by the lower-level laboratory measuring instruments, but also evaluates the technical level of the lower-level measurement personnel and the errors introduced by the laboratory working conditions. Wait. In our country, this method is also applied in some specific on-site verification, calibration, and testing fields, but the "transfer standard" is not easy to obtain, and it is repetitive, labor-intensive and time-consuming. Therefore, it has not been widely promoted.
中国合格评定国家认可委员会(CNAS)为验证境内校准实验室的测量能力, 推出了“能力验证计划”或“测量审核”,要求各实验室进行盲样比对:即主持盲样比对的实验室先挑选一批性能稳定的“样品”,按照相应的检定规程/校准规范或比对规范,对该批“样品”进行测量,且测量数据存档,然后将已知测量数据的“样品”寄给与之比对的实验室,但该样品的相关测量数据对与之比对的实验室保密,然后要求与之比对的实验室按照相应的检定规程/校准规范或比对规范对同一样品进行测量,并将该样品及测量数据一同寄回主持比对的实验室,由主持比对的实验室对相关测量数据进行处理,从而对与之比对的实验室的测量能力进行验证,因为比对样品的相关数据在比对前后并未公开,故称盲样比对。CNAS推出的这种“能力验证计划”或“测量审核”方案与MAPS的量传或溯源方式大抵一致,故与MAPS方式同类。In order to verify the measurement capabilities of domestic calibration laboratories, the China National Accreditation Service for Conformity Assessment (CNAS) has launched a "proficiency testing plan" or "measurement audit", requiring each laboratory to conduct a blind sample comparison: that is, to host a blind sample comparison experiment The laboratory first selects a batch of “samples” with stable performance, measures the batch of “samples” according to the corresponding verification procedures/calibration specifications or comparison specifications, and archives the measurement data, and then sends the “samples” with known measurement data To the compared laboratory, but the relevant measurement data of the sample is kept confidential to the compared laboratory, and then the compared laboratory is required to compare the same sample in accordance with the corresponding verification procedures/calibration specifications or comparison specifications Perform measurement, and send the sample and measurement data back to the laboratory in charge of the comparison, and the laboratory in charge of the comparison will process the relevant measurement data to verify the measurement ability of the compared laboratory, because The relevant data of the compared sample is not disclosed before and after the comparison, so it is called blind sample comparison. The "proficiency testing plan" or "measurement audit" program launched by CNAS is roughly the same as the MAPS method of mass transmission or traceability, so it is similar to the MAPS method.
现有量传或溯源方式中的第一种、第二种、第四种量传或溯源方式虽然采用的计量器具、量传或溯源流程有所差别,但实质内容差异不大,均为用实物标准进行面对面的本地量传或溯源的方式。这类量传或溯源方式,无论是欲量传或溯源的单位将其待检计量器具送至上级计量检定/校准机构进行检定/校准(简称送检),还是欲量传或溯源的单位请上级计量检定/校准机构的技术人员到自身现场来对待检计量器具进行检定/校准(简称“下厂”),若从劳动生产率考虑,则其绝大多数量传或溯源过程均属于单件纯手工生产,加上送检或联系工程师下厂存在诸多不便因素,使得这类量传或溯源方式存在如下问题:Although the first, second, and fourth methods of mass transmission or traceability in the existing mass transmission or traceability methods are different in measuring instruments, mass transmission or traceability processes, the substantial content of them is not much different. The physical standard is a way of face-to-face local quantity transmission or traceability. For this type of measurement transmission or traceability method, whether it is the unit that wants measurement transmission or traceability to send its measurement instrument to be inspected to the higher-level measurement verification/calibration institution for verification/calibration (referred to as sending inspection), or the unit that wants measurement transmission or traceability, please The technicians of the higher-level metrological verification/calibration institutions come to their own site to perform verification/calibration of the measuring instruments to be inspected (referred to as "off the factory"). If considering the labor productivity, most of the measurement or traceability processes are single-piece pure manual Production, coupled with many inconvenience factors in sending inspection or contacting engineers to go to the factory, make this type of quantity transmission or traceability method have the following problems:
1)、整个量传或溯源过程几乎纯手工操作,不仅人工成本高,且准备和操作时间过长、效率低下、及时率低,完成某件计量器具的量传或溯源过程少则三五天、多则十几天、甚至一两个月,与现代社会自动化、智能或智慧化生产实时、高效的要求很不适应。1) The entire mass transfer or traceability process is almost purely manual operation, not only the labor cost is high, but also the preparation and operation time is too long, the efficiency is low, and the timely rate is low. The process of completing the mass transfer or traceability of a measuring instrument can take as little as three to five days , As long as ten days, or even one or two months, it is not suitable for the real-time and high-efficiency requirements of modern society's automation, intelligent or intelligent production.
2)、无论是请工程师下厂还是人工送检等均需人工搬运计量器具,不仅费工费时,而且因人工拆卸、搬运和路途运输造成的计量器具损坏事件时有发生。2). Whether it is to ask the engineer to go to the factory or send it for inspection manually, it is necessary to manually move the measuring instrument, which is not only time-consuming, but also damage to the measuring instrument caused by manual disassembly, handling and road transportation.
3)、现有量传方法是由计量基准器具逐级传递到各级的计量标准器具直至工作计量器具,各传递环节的测量数据得不到及时反馈,无法保证用户实验室传递数据的及时性、准确性和可靠性。3) The existing volume transmission method is from the measurement standard instrument to the measurement standard instrument at all levels to the working measurement instrument. The measurement data of each transmission link cannot be fed back in time, and the timeliness of the data transmitted by the user laboratory cannot be guaranteed. , Accuracy and reliability.
4)、送检计量器具的检定/校准结果是在上级计量技术机构的标准实验室的特定的环境条件下测得的,与客户现场实际使用环境条件往往差别很大。4) The verification/calibration results of the measuring instruments submitted for inspection are measured under the specific environmental conditions of the standard laboratory of the higher-level metrology technical institution, which are often very different from the actual use environmental conditions on the customer's site.
5)、目前,绝大多数计量器具均有个固定的检定周期或校准时间间隔。而在该固定的检定周期或校准时间间隔里,有些已经超差,有些性能完好仍然合格。超差的计量器具若不撤下来,仍向下量传,将造成极大危害;而性能良好未超差的计量器具再检(校)一遍又势必浪费了大量的人力物力。所以,政府的 要求是:宁愿牺牲人力物力也要保证计量器具按固定检定周期或校准时间间隔送检以保证量值的准确可靠;对那些关键的计量器具还要求在计量器具的一个检定周期或校准时间间隔内,在被检(校)计量器具现场再额外增加期间核查(运行检查)程序。期间核查(运行检查)程序虽然操作上比正规的检定或校准程序要简便很多,因为它只考核计量器具的稳定性,但因现场人员成本及技术问题,该期间核查(运行检查)程序基本上很难长期坚持下来。5) At present, most measuring instruments have a fixed verification period or calibration time interval. In the fixed verification period or calibration time interval, some are out of tolerance, and some are still qualified if their performance is intact. If measuring instruments that are out of tolerance are not removed, they will still be passed down, which will cause great harm; and re-inspection (calibration) of measuring instruments that have good performance and not out of tolerance will inevitably waste a lot of manpower and material resources. Therefore, the government’s requirement is: I would rather sacrifice manpower and material resources to ensure that the measuring instruments are sent for inspection at a fixed verification cycle or calibration interval to ensure the accuracy and reliability of the measurement; for those key measuring instruments, it is required to be in a verification cycle or During the calibration time interval, an additional period inspection (operation inspection) procedure is added at the site of the inspected (calibrated) measuring instrument. Although the periodical verification (operational inspection) procedure is much simpler in operation than the formal verification or calibration procedure, because it only assesses the stability of measuring instruments, due to on-site personnel costs and technical problems, the periodical verification (operational inspection) procedure is basically It is difficult to persist for a long time.
6)、作为MAPS的“传递标准”或CNAS“能力验证计划”的比对“盲样”均为量值稳定且便于携带或搬运的“实物量具”或实物标准,其应用局限性较大,只能在局部或特定条件下使用,而且在MAPS的标准传递或CNAS“能力验证计划”的“盲样”比对时,需要上下级计量技术机构工作人员对参与量传或溯源的计量器具进行多次重复测量且往返运输2次或2次以上,费工费时,此种方式用于管理部门或上级计量技术机构对相关(同级或下级)计量技术机构的能力验证(或考核)尚可,但不适合量大面广的计量器具尤其是工作计量器具的周期性的量传或溯源的需要。6). The “blind samples” used as the “transmission standard” of MAPS or the “proficiency testing plan” of CNAS are all “physical measuring tools” or physical standards that are stable in value and easy to carry or carry, and their application is limited. It can only be used under partial or specific conditions, and when the standard transmission of MAPS or the "blind sample" comparison of the CNAS "proficiency testing plan" is required, the staff of the upper and lower measurement technology institutions are required to conduct the measurement instruments participating in the measurement transmission or traceability. Repeated measurement for many times and round-trip transportation 2 or more times, which is time-consuming and labor-intensive. This method is acceptable for the proficiency verification (or assessment) of the relevant (same level or lower-level) measurement technical institution by the management department or higher-level measurement technical institution , But it is not suitable for measuring instruments with a large quantity and a wide range, especially the need for periodic measurement or traceability of working measuring instruments.
上述的第三种“用发播标准信号进行量传或溯源”的量传或溯源方式,虽然不需人工搬运计量器具,节省了运输成本,缩短了送检的准备时间,但目前这种量传或溯源方式:The above-mentioned third method of “quantity transmission or traceability by broadcasting standard signals” does not require manual handling of measuring instruments, which saves transportation costs and shortens the preparation time for inspection. Transmission or traceability method:
1)、只适合于不需借助实物量具来传递或溯源、且信号的传输路径不对其准确度产生较大影响的时频信号传输(如“GPS卫星共视法远程时频传递”、“飞秒激光频率梳时频远程校准”)或电视标准格式比率信号的无线远程量传或溯源等极少数情况,其它计量领域难以推广应用。1). It is only suitable for time-frequency signal transmission that does not require physical measuring tools for transmission or traceability, and the signal transmission path does not have a significant impact on its accuracy (such as "GPS satellite common-view method long-distance time-frequency transmission", "flying Second laser frequency comb time-frequency remote calibration") or wireless remote measurement or traceability of TV standard format ratio signals, etc. It is difficult to popularize and apply in other measurement fields.
2)、现有量传或溯源过程自动化程度低,信号捕捉、调试、稳定等诸多操作过程几乎纯手工操作,费工、费力又费时。2) The existing volume transmission or traceability process has a low degree of automation, and many operations such as signal capture, debugging, and stability are almost purely manual operations, which is laborious, laborious and time-consuming.

在优选实施例中,计量器具管理系统800还包括专家系统85。专家系统85是一个或一组能在某些特定领域内,应用大量的专家知识和推理方法求解复杂问题的一种人工智能计算机程序,属于人工智能的一个发展分支。专家系统85的研究目标是模拟人类专家的推理思维过程。一般是将领域专家的知识和经验,用一种知识表达模式存入计算机,系统对输入的事实进行推理,做出判断和决策。In a preferred embodiment, the measuring instrument management system 800 further includes an expert system 85. Expert system 85 is an artificial intelligence computer program or a group of artificial intelligence computer programs that can apply a large amount of expert knowledge and reasoning methods to solve complex problems in certain specific fields. It belongs to a development branch of artificial intelligence. The research goal of expert system 85 is to simulate the reasoning thinking process of human experts. Generally, the knowledge and experience of domain experts are stored in the computer using a knowledge expression mode, and the system makes inferences on the input facts, makes judgments and decisions.
专家系统85由以下组件组成:人机接口、知识获取机构、推理机、解释器、知识库及其管理系统、数据库及其管理系统等,其中基本结构中大部分为知识库、数据库和推理机。详述如下:The expert system 85 is composed of the following components: human-machine interface, knowledge acquisition mechanism, inference engine, interpreter, knowledge base and its management system, database and its management system, etc., among which most of the basic structures are knowledge base, database and inference engine . The details are as follows:
人机接口:是专家系统与用户进行交流的界面,与知识获取机构、推理机、解释器相联,一般由键盘、显示器和其它输入/输出设备组成。通过人机接口,用户向系统输入相应知识、必要数据、参数等信息,并回答系统提出的相关问题,系统则向用户输出推理结果及相关的解释等。Man-machine interface: It is the interface for the expert system to communicate with the user. It is connected with the knowledge acquisition mechanism, the reasoning machine, and the interpreter. It is generally composed of a keyboard, a display and other input/output devices. Through the man-machine interface, the user inputs the corresponding knowledge, necessary data, parameters and other information into the system, and answers related questions raised by the system, and the system outputs the reasoning results and related explanations to the user.
知识获取机构:与人机接口和知识库相联,是专家系统知识库是否优越的关键,通过知识获取,可以扩充和修改知识库中的内容,也可以实现自动学习功能。知识获取负责建立、修改和扩充知识库,是专家系统中把问题求解的各种专门知识从人类专家的头脑中或其他知识源那里转换到知识库中的一个重要机构。知识获取可以是手工的,也可以采用半自动知识获取方法或自动知识获取方法。Knowledge acquisition organization: It is connected with the human-computer interface and the knowledge base, which is the key to the superiority of the expert system knowledge base. Through knowledge acquisition, the content in the knowledge base can be expanded and modified, and the automatic learning function can also be realized. Knowledge acquisition is responsible for the establishment, modification and expansion of the knowledge base. It is an important institution in the expert system that converts various specialized knowledge of problem solving from the minds of human experts or other knowledge sources to the knowledge base. Knowledge acquisition can be manual, semi-automatic knowledge acquisition methods or automatic knowledge acquisition methods can also be used.
推理机:与人机接口、知识库、数据库相联,是实施问题求解的核心执行机构。它对知识库中的相关知识进行解释执行,并把结果记录到动态库的适当空间中。推理方式可以有正向和反向推理两种。正向推理是从条件(前件)匹配到结论(后件),反向推理则先假设一个结论成立,看它的条件有没有得到满足。推理机和知识库既相互分离又相辅相成:推理机的程序与知识库的具体知识内 容无关,使得对知识库的修改无须改动推理机程序,但不同知识类型的求解程序又根据不同知识类型的特征而编制,且相互印证。Inference engine: It is connected with human-machine interface, knowledge base, and database, and is the core executive body for problem solving. It interprets and executes the relevant knowledge in the knowledge base, and records the results in the appropriate space of the dynamic library. The reasoning method can be forward and backward reasoning. Forward reasoning is to match the condition (the antecedent) to the conclusion (the latter), while the reverse reasoning first assumes that a conclusion is established and sees whether its conditions are met. The inference engine and the knowledge base are both separate and complementary: the program of the inference engine has nothing to do with the specific knowledge content of the knowledge base, so that the modification of the knowledge base does not need to change the inference engine program, but the solving procedures of different knowledge types are based on the characteristics of different knowledge types And prepare, and mutually confirm.
解释器:与人机接口、数据库相联,用于对求解过程做出说明,并回答用户的提问。两个最基本的问题是“Why”和“How”。解释器让用户理解程序正在做什么和为什么这样做。为了回答“为什么”得到某个结论的询问,系统通常需要反向跟踪动态库中保存的推理路径,并把它翻译成用户能接受的自然语言表达方式。解释器能够根据用户的提问,对结论、求解过程做出说明。Interpreter: connected with the human-machine interface and database, used to explain the solution process and answer user questions. The two most basic questions are "Why" and "How". The interpreter allows the user to understand what the program is doing and why. In order to answer the question of "why" a certain conclusion is obtained, the system usually needs to backtrack the reasoning path stored in the dynamic library and translate it into a natural language expression acceptable to the user. The interpreter can explain the conclusion and the solution process according to the user's question.
知识库:用来存放专家提供的求解问题所需的领域知识的集合,是专家系统的核心组成部分。专家系统的问题求解过程是通过知识库中的知识来模拟专家的思维方式,因此,知识库中知识的质量和数量决定着专家系统的质量水平。知识的表示形式可以是多种多样的,包括框架、规则、语义网络等等。一般来说,专家系统中的知识库与专家系统程序是相互独立的,用户可以通过改变、完善知识库中的知识内容来提高专家系统的性能。知识库的建造需要知识工程师和领域专家相互合作把领域专家头脑中的知识整理出来,并用系统的知识方法存放在知识库中。当解决问题时,用户为系统提供一些已知数据,并可从系统处获得专家水平的结论。Knowledge base: It is used to store the collection of domain knowledge required to solve the problem provided by experts, and is the core component of the expert system. The problem-solving process of the expert system is to simulate the way of thinking of experts through the knowledge in the knowledge base. Therefore, the quality and quantity of knowledge in the knowledge base determine the quality level of the expert system. The representation of knowledge can be diverse, including frameworks, rules, semantic networks, and so on. Generally speaking, the knowledge base in the expert system and the expert system program are independent of each other, and users can improve the performance of the expert system by changing and perfecting the knowledge content in the knowledge base. The construction of the knowledge base requires the cooperation of knowledge engineers and domain experts to sort out the knowledge in the minds of the domain experts and store them in the knowledge base using systematic knowledge methods. When solving the problem, the user provides some known data to the system and can obtain expert-level conclusions from the system.

To the level of super first-class experts.
人工智能中的知识表示形式虽有产生式、框架、语义网络等,但在专家系统85中运用得较为普遍的知识是产生式规则。产生式规则以IF…THEN…的形式出现,就像BASIC等编程语言里的条件语句一样,IF后面跟的是条件(前件),THEN后面的是结论(后件),条件与结论均可以通过逻辑运算AND、OR、NOT进行复合。如果前提条件得到满足,就产生相应的动作或结论。Although the knowledge representation in artificial intelligence includes production, framework, semantic network, etc., the more common knowledge used in expert system 85 is production rules.
