摘要:
针对大学物理实验中的压力传感器特性测量实验存在测量精确度低、计算复杂、特性描述差等问题,文章基于单片机控制与计算机分析相结合的方案,设计了压力传感器特性测量实验系统。通过利用精密仪表放大器AD620、模数转换器ADC0809、MCS-51单片机和电平转换电路MAX232等构成的主体电路采集压力非平衡电桥的电压值,采用计算机对数据进行处理分析,从VB编译的人机交互界面中得到传感器灵敏度,非线性度及滞后误差等特性结果。此系统测量压力传感器特性的准确率更高,特性曲线更直观。
Abstract:
The original experimental instrument for measuring the pressure transducers characteristics have some problems, such as low accuracy, complexity and poor description. Based on singlechip microcomputer and computer analysis, a system for measuring the characteristics of pressure transducer is designed. The main circuit consists of precision instrument amplifier AD620, ADC0809,MCS51 SCM and MAX232 etc. By collecting the voltage of nonbalanced electric bridge and analyzing the data by computer, characteristic results such as sensitivity, linearity and hysteresis error will show up in the computer interface which is compiled by VB. Results show that the system can give higher accuracy and more intuitive characteristic curve.
