引言

生产过程质量数据采集系统主要应用于制造型企业的智能工厂中，能够对其生产车间的生产过程质

量数据进行实时监控和采集，并输入到系统内部的统一接口，不断对数据库进行充实，实现动态实时采

集和分析。由于生产过程质量数据采集系统可采用多种不同的采集方式和采集设备，因此对于生产过程

质量数据采集系统的性能评估和校准方法尚未形成统一规范。

生产过程质量数据采集系统（PQDAS）的性能是指在规定的工作条件和环境条件下，能够执行所

提供功能的程度。系统能在规定的响应时间内准确地执行系统所需的任务，如果系统执行多个任务，则

在不相互妨碍的情况下处理和执行这些任务。因此，指示在一个时间范围内可执行的任务数目的能力非

常重要。当一个系统要同时完成几项任务时，其性能会发生变化，这就需要分别对每一项任务的执行情

况进行分析。

因此，为了评估系统的性能，有必要以分层的方式对系统属性进行分类。性能的子特性包括：精确

度、响应时间、处理能力、可信性、智能化能力。

性能不能直接评估，需要通过分析和测试其子特性加以确定。为了能确定各种子特性，可通过信息

转换对系统进行分析，通过系统的每一条信息流检查子特性。

系统的性能首先取决于系统的设计，其次取决于在系绕的制造和集成阶段（通过硬件和软件）可能

引入的因素。

性能的各种子特性之间存在相互依存关系。系统的性能可能没有统一的衡量尺度，因为不同的任务

可有不同数量的信息转换。当这些信息转换合用公共设施时，它们之间存在相互依存关系。

有关性能的评定技术主要有分析法评定技术、试验法评定技术、影响条件下的试验。具体可按照

GB/T18272.4—2006第8章的要求进行。

本文件对生产过程质量数据采集系统的评估特性、影响因素进行了说明，给出了规范统一的性能评

估和校准方法，帮助实现生产过程中数据采集和分析的自动化和智能化。
