An out-of-range signal indicates an overflow condition, which can be used with the most significant bit to determine low or high overflow. 超量程信号表示溢出状况,可由最高有效位来确定是下溢还是上溢。
In view of the uncertainty of the load and the randomness of the response signal, the wavelet analysis is used to process the collection of vibration signals, so as to avoid the observation overflow. 针对结构承受荷载的不确定性以及响应信号的随机性,运用小波分析对振动信号进行采集处理,避免了观测溢出。
Applying wavelet denoise to improve the test signal, the dynamic characteristic parameters of a overflow valve were obtained by selecting characteristic point of the signal. 此系统应用小波降噪的方法提高测试信号的质量,然后提取信号特征点,得到溢流阀动态特性的各项参数。
