| 摘 要： | 针对现今出现的越来越多的燃气使用安全问题,介绍了燃气表气密性检测在日常生活中的必要性以及重要意义,并且设计了基于直压法原理的以C8051F350单片机为控制核心的气密性检测仪系统.该系统采用主、副控制板分级控制的形式,在检测时更具有灵活性.同时利用高精度差压变送器测量压力,并通过24位A/D转换器对检测信号进行处理,从而实现对微小信号的捕获和放大.最后通过不确定度分析证实所得实验数据满足要求.

| Abstract: | According to the more and more safety problems appeared in the use of fuel gas currently,the necessity and significance of air-tightness detection for the gas meter in daily life were introduced.An air-tight property detector based on the principle of direct pressure with the C8051F350 MCU as the control core was designed.It was controlled in the form of hierarchical by lord vice panel,and was with more flexible in detecting.The pressure was measured by the high accuracy differential pressure transmitter an... |
