摘要
针对传统的压力变送器,给出了一种超低功耗无线智能压力变送器的设计方案。详细介绍了变送器中压力传感器的测量电路原理,同时给出了该测量电路的可行性的分析过程;并在此基础之上给出了一种用曲面拟合实现二传感器的数据融合的方法,从而实现对电容式压力传感器的标定。
In view of the traditional pressure transmitter, a design of uhralow power wireless intelligent pressure transmitter is presented, and the principle of sensor measuring circuit is introduced in detail. At the same time, it gives the feasibility analysis process of measurement circuit. A curve surface consolidation data fusion method is applied to solve the problem of calibrating the value of the capacitive pressure sensor.
