摘要
为实现气相色谱仪温度参数的自动化检定,设计了一套新型的温度自动检定系统。给出了温度数据采集仪的组成和模块设计,采用Android Studio开发环境,串口通信技术,完成了Java编程的Android手机端应用软件,实现了温度的测量和气相色谱仪的柱箱温度稳定性、程序升温重复性的自动检定。最后对温度数据采集仪准确性进行验证,在测量范围内示值误差均小于0. 30℃,证明了该设计的可行性。与传统的检定方法相比,本文设计的气相色谱仪温度自动检定系统提高了工作效率,为检定人员减负减压。
In order to automatically verify the temperature parameters of the gas chromatograph,a new automatic temperature verification system is designed.This paper presents the composition and module design of the temperature data acquisition instrument.The Android mobile phone terminal application software by Java programming is completed by the Android Studio development environment and the serial communication technology.The temperature measurement using and automatic verification of the column box temperature stability and the program temperature repeatability of the gas chromatograph are realized.Finally,the accuracy of the temperature data acquisition instrument is verified by the measurement and calibration.The error of the indicated value within the measurement range is less than 0.30℃,which proves the feasibility of the design.Compared with the traditional method,the automatic temperature verification system of gas chromatograph designed in this paper improves the working efficiency and reduces the buraden and pressure for the verifier.
