航空系统目前使用的数字多用表涉及的厂家和型号各不相同,准确度等级也不一样。为了保障工作过程的可靠和安全,必须定期对这些数字多用表进行检定。为此,本文引进了福禄克公司的多功能标准器FLUKE5720作为检定源表,设计了一款全新的数字多用表校准软件。软件引入可扩展标记语言XML技术,且以XML作为软件的配置管理文件,实现了用一套软件检定厂家各异、品牌各异的数字多用表,可使检定系统兼容性大幅提高。
The current multimeter used in aviation systems is different in terms of manufacturer and model, and the accuracy level is also different. In order to ensure the reliability and safety of the work process, these DMMs must be checked regularly. To this end, this article introduced the Fluke company’s multi-function standard FLUKE5720 as a verification source table, designed a new digital multimeter calibration software. The software introduces extensible markup language XML technology, and takes XML as the configuration management file of the software, and realizes the digital multimeter with different brands and manufacturers’ approval by a set of software, which can greatly improve the compatibility of the verification system.
