【摘要】 为了精确测量海水温度,该文设计了一种基于铂电阻的多路海水检测系统。系统前端采用内置PGA的24位高精密的模数转换器ADS1256对来自铂电阻的信号进行放大以及AD转换。主控制器采用的是ST公司的32位ARM内核微处理器STM32F103。系统把采集到的数据预处理后存放到大容量SD中。连接水上甲板单元时,水下系统通过串口把数据传输到甲板PC上,以便实时观测到水下采集数据。更多还原

【Abstract】 To measure seawater temperature accurately,this paper designed based on multi-platinum resistance seawater detection system.The front of the system with built-in 24 PGA ADC ADS1256 high-precision platinum resistance from the signal amplification and AD conversion.Master controller is ST’s 32-bit ARM core microprocessor STM32F103.The system stores the collected data to high-capacity SD as a backup.When connected to deck unit,underwater system can also transfer the data through the serial port on the PC to the deck so that we can observe underwater data of real-time.更多还原
