| 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。

| 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 i.he PC to the deck so that we can observe underwater data of real-time. |
