集成微型自适应加速度测试仪研究

Study on an Integrated Micro Self Adaptive Sampling Acceleration Recorder

提供了一种采用硅微加速度计和ＡＳＩＣ构成的自适应采集和存储测试加速度信号波形的集成微型测试仪。该测试仪有１２８种采样频率随被测信号实时自适应改变，最高采样频率为１０ＭＨｚ，存储容量可达１Ｍ字节，单电源５Ｖ供电，采集时功耗５０ｍＷ，保存数据时的功耗为２０μＷ，测量范围±５００ｇ，抗过载能力为３０倍量程，具有系统自检功能，自带微机接口，而其整体体积仅有２．４ｃｍ３。

The paper presents an integrated micro acceleration waveform recorder that consists of a silicon accelerometer,a self adaptive sampling and storage memory and button batteries.A special IC has been developed for the recorder.
