Design and exploration of a remote metrology system for environmental test equipment in accordance with JJF 1101-2019
基于JJF1101-2019的环境试验设备远程计量系统设计与探索

摘要

环境试验设备是工业产品可靠性检测、材料性能验证的核心装备，其温度、湿度参数的计量准确性直接决定试验结果的可信度。JJF1101-2019《环境试验设备温度、湿度参数校准规范》为传统现场计量提供了标准化依据，但传统计量模式存在效率低下、多设备同步校准困难的痛点。本文以该规范为基础，设计一套环境试验设备远程计量系统，通过增设远程数据传输模块，实现计量数据的远程实时接收与分析；结合两大创新点，即数据传输安全防护机制与自设计快速模块组装支架，实现多实验室、多台设备的同步计量。为环境试验设备远程计量方法的后续推广与优化提供理论支撑与实践参考。

Abstract

Environmental test equipment serves as core facilities for reliability testing of industrial products and performance verification of materials. The metering accuracy of its temperature and humidity parameters directly affects the credibility of test results. JJF 1101-2019 Calibration Specification for Temperature and Humidity Parameters of Environmental Test Equipment provides a standardized basis for conventional on-site metering. Nevertheless, the traditional metering mode suffers from low efficiency and difficulties in synchronous calibration of multiple devices. Based on the above specification, this paper develops a remote metering system for environmental test equipment. By equipping a remote data transmission module, the system realizes real-time remote reception and analysis of metering data. With two innovative designs—a data transmission security protection mechanism and a self-developed rapid modular assembly bracket—synchronous metering for multiple laboratories and devices is achieved. This study offers theoretical support and practical references for the further promotion and optimization of remote metering methods for environmental test equipment.
