摘要
设计了电磁计程仪测速传感器微弱信号的检测电路,利用频谱分析、互相关运算等方法对信号进行了处理,与现有传感器信号处理方法相比,具有精度高、抑制噪声能力强、检测电路体积小、携带方便的优点。为检测传感器工作状态提供了有力的帮助。
Inspection circuits of electromagnetic signed. The signals are processed by spectrum analysis log velocity measurement sensor for weak signals are de- and cross correlation operation method. Comparing with the present methods of sensor signal process, the method has the characteristics of high accuracy, good noise suppres- sion, small inspection circuits and easy to carry. It is helpful to inspect the operation states of sensors.
