摘要
设计了基于皮托管原理的风速传感器,主要围绕皮托管原理测量风速的方法,通过对风压的获得,将微小信号经过放大去噪声转化成可以提取的电信号,结合风速与风压的转换模型获得风速测量数据并通过通讯接口传输出去,电路符合本质安全设计工作稳定性,抗电磁干扰能力更强。
A wind speed sensor based on the principle of pitot tube is designed. This paper mainly focuses on the method of measuring wind speed by the principle of pitot tube. Through the acquisition of wind pressure, the small signal is transformed into an electrical signal that can be extracted by amplifying and removing noise. Combined with the wind speed and wind pressure conversion model, the wind velocity measurement data is obtained and transmitted through the communication interface. The electric circuit is consistent with the stability of the essential safety design work, and anti-electromagnetic interference ability is stronger.
