ADS1255及其在数字地震检波器中的应用
|
摘要
针对煤矿井下地震勘探检波器要求全空间、高速、高精度的特点,选用ADS1255模数转换器作为数字地震检波器的核心部件。文中介绍了ADS1255的主要特点、构成、工作原理,及其在数字检波器中硬件实现和软件设计流程、试验。所设计的数字检波器达到了煤矿井下微型化、低功耗、高速、高精度的要求。
According to the reguirements of whole space,high-speed and high precision detector in seismic exploration for coal mine,the ADS1255 ADC is choiced as the core component of digital geophone.This paper introduces the main features,composition,working principle of the ADS1255,the hardware and software design process of the digital detector.The designed digital detectors meet the requirements such as miniaturization,low power,high-speed and high-precision coal mine exploration.
