Description
本发明涉及测量仪器远程校准的系统与实现方法，特别是涉及一种用于由计算机测控的测量仪器的远程校准系统与方法，依据校准规范，满足质量控制要求，确保远程校准行为、原始测量数据、电子校准证书可信可靠系统与方法。
为了确保测量的质量和量值的统一，测量仪器需要定期校准与检定。实验室的测量仪器往往采用两种方式，一是针对小型测量仪器，通常是把测量仪器送到有资质的仪器校准机构，依据校准规范和质量控制要求对测量仪器进行校准，出具校准证书。二是针对较大的测量仪器，通常是有资质的校准员携带标准器(或标准品)到仪器实验室对测量仪器依据校准规范和质量控制要求进行校准，出具校准证书。
随着社会发展与进步，需要定期检定校准的测量仪器越来越多，按照传统的工作方式需要大量的人力成本，特别是有疫情期间，人员出差流动不便，造成大量测量仪器难以按时定期校准与检定。
测量行业与计量机构都渴望可靠可信的远程校准系统。
为了实现远程校准，有如下几种解决方案：一是修改校准规范，重新制定远程校准规范，这周方案周期长，实验方案需要多轮测试与验证；二是在测量仪器上增加远程校准的模块或子系统，不同仪器需要定制开发不同的远程校准子系统，也需要修改校准规范，这种方案也存在周期长，实验方案需要多轮测试与验证的问题。
对于由计算机测控的测量仪器的校准，其校准活动是有资质的校准员采用 标准器(或标准品)到依据校准规范和质量控制要求操作仪器计算机对测量仪器进行校准，获得测量数据，形成测量报告。
这类由计算机测控的测量仪器的校准在实现远程校准的方案中，可以不修改校准规程，通过远程操控仪器的计算机，依据校准规范完成测量的工作。但是这种方案往往不符合校准的质量控制要求。问题如下：
1)难以确定是否对标准器(或标准品)进行测量
2)难以确定原始测试数据的完整性和真实性
3)难以确定测量环境参数的完整性和真实性
4)难以确定本次校准活动是由有资质的校准员校准的
5)难以确定本次校准的时间可信性
正是存在上述诸多质量控制要求难以满足，因此，由计算机测控的测量仪器的远程校准方案和系统一直没有解决。
如何在满足测量仪器校准规范、校准质量控制要求的提前下，对计算机测控的测量仪器实现远程校准，是测量行业与计量机构需要解决的难题。
发明内容
为了解决上述问题，本发明的目的在于提出一种用于由计算机测控的测量仪器的远程校准系统与方法，从而实现对由计算机测控的测量仪器远程校准，符合校准规范，确保远程校准行为、原始测量数据、电子校准证书可信可靠，满足质量控制要求。
相对于修改校准规范、在仪器上增加远程校准终端子系统的方法，本发明在实现时间周期、实现成本上具有显著优势。
相对于仅远程操控仪器的计算机方案，本发明具有测量数据完整性和安全 性，满足校准质量控制要求的显著优势。
1)校准过程中，确保被校准的仪器测量的确实是标准器(或标准品)，使用防伪二维码唯一标识的标准器(或标准品)。防伪二维码明确标准器的应用时间范围、校准对象、校准操作范围、校准员、校准机构与被校准机构等信息，只有当标准器监测摄像头获得的二维码识别后的信息与校准服务器一致才能确认为合格标准器。校准过程不仅全程录像，信息防伪、容易核验、便于质量核查，本发明对标准品质量控制要求具有显著优势。
2)每次校准测量的原始数据都自动上传服务器，并打时间戳，确保原始测量数据不能修改，确保数据的完整性和安全性，不仅作为校准报告的原始支撑材料，而且作为质量控制要求的基本组成部分。相对与手写或填报的原始测量数据表，具有显著的质量控制优势。
3)远程校准终端直接获取仪器校准环境的温度、湿度、位置参数，并打时间戳，不仅是数据点，而且是环境参数的健康曲线，不需要人员参与(避免数据造假和误写)，相对与手写或填报的环境参数，具有显著的质量控制优势。
4)校准员在远程校准前不仅需要输入账号密码，而且校准过程对其进行其人脸拍照和视频录像，并打时间戳，确保此操作为有校准资质人员操作，避免非合格人员生成校准证书。
5)远程校准终端、校准员用软件系统、远程校准服务器等都进行时间网络协同，开始校准、采集数据、结束校准、出证书都打时间戳，确保远程校准活动的时间可靠可信。具有明显优势。
