摘　　要：传统的补偿式微压计测量采用手动测量、人眼读数的方式实现数据的获取,人眼读数误差所引入的不确定度在装置整体不确定度中占有很大比重。本文研制了一种全自动补偿式微压计,利用高清摄像头代替人眼读数,利用软件对所采集的图片进行逻辑分析,同时增加传统补偿式微压计不具备的实时液相温度测量、实地重力加速度测量及大气压测量功能,有效减小各影响量对测量结果的干扰。采用滑台电机控制位移,进一步提高测量准确度。经实验证明,本文研制的全自动补偿式微压计具有很好的准确性与可靠性。The traditional measurement method of compensated micro-manometer adopts manual measurement and human eye reading mode to achieve data acquisition.The uncertainty introduced by human eye reading error accounts for a large proportion in the overall uncertainty of the device.In this paper,a full-automatic compensation type micro manometer is developed.A high-definition camera is used to replace the human eye reading,and the software is used to make logical analysis of the collected pictures.At the same time,the functions of real-time liquid phase temperature measurement,field gravity acceleration measurement and atmospheric pressure measurement,which are not available in the traditional compensation type micro-manometer,are added to effectively reduce the interference of each influence on the measurement results.The sliding table motor is used to control the displacement to further improve the measurement accuracy.The experimental results show that the automatic compensation type micro-manometer developed in this paper has high accuracy and reliability.
