摘要
针对深海探测领域温深数据获取实时性要求不高但精确度要求很高的应用需求,现选取24位多通道高精度A/D转换芯片ADS1258结合STM32F103 ARM控制器芯片,实现多通道温深监测装置采集功能。另外,通过降低AD芯片采样率使用,还提出了一种采样点数据/每秒求平均值方法,这样在减少了数据传输吞吐量情况下保证了采集数据传输的稳定性和精确度。文中阐述了系统工作基本原理、多通道高精度数据采集软硬件设计、采集数据平均处理并给出了典型的实验室验证结果。
In the deep sea test field, the real-time requirements of temperature and depth data acquisition are not high but high precision application. The 24-bit multi-channel high precision A/D conversion chip ADS1258 and STM32F103 ARM control ship are selected to realize the acquisition function of multi-channel temperature and depth monitoring device. In addition,by reducing AD the sampling rate, a sampling point data per second in averaging method is proposed,this ensures the stability and accuracy of the collected data transmission while reducing the data number. This paper describes the basic principle, multichannel high precision data collecting system design, average processing and typical test results are given.
