摘　　要：针对目前国内生产的钟罩装置多采用人工操作,在检测中需要测得被检表前和标准装置内部的温度、压力以及标定时间、体积流量、累计流量等一系列数据,再进行计算,其工作量大、数据多,且原有装置的同步控制由人工操作来保证,检定过程中存在效率低、操作繁琐等弊端,容易因人为的失误增大检定误差甚至产生错误,并且数据查询困难。因此,笔者研制了由ARM7微处理器为下位机和计算机为上位机的钟罩气体流量标准装置控制自动检定系统,以实现对检定过程的自动控制及数据处理。The bell prover produced by enterprise in China almost operate by human, in the process of calibrating, operator must measure the temperature、pressure,time,cumulative flow and instantaneous flow data and to note and calculate them, it has a lot of data and takes a lot of time to calculate and cassette. The synchronization in the original equipment operated by human, it has shortcoming of low detection efficiency and hard to operate, it can cause mistake or error because of human operating and it hard to inquire. So a system designed by author composed by ARM7 and computer to achieve the automatic control and data process.
