摘要
对标度变换技术进行了介绍,并基于某弹载数据采集系统的研制过程,给出了利用标度转换技术对弹体表面压力传感器信号的处理方法。建立了传感器输出信号与模数转换数据之间的对应关系,并利用活塞式压力计对数据处理结果进行了验证。给出了采用此压力传感器取得的弹射试验相关监测参数的记录曲线。结果表明:由压力传感器和弹载数据采集系统组成的测量装置完全能够再现弹体外部压力变化。
The technology of scale conversion is introduced. Based on R ＆ D process of a missile-borne data acquisition system, scale conversion technology is used to process the surface pressure signal. The specific methods on the data processing of establishing the relationship between the sensor output signal and analog-to-digital conversion of data are given, and are verified by using piston-type pressure gauge. Given the relavant curve of a ejection test is given by using pressure sensor.
