| 摘 要： | 提出一种抛弃式海水温度测量仪数据传输系统的设计方案。针对传输信道距离长,波形畸变大的特点,采用频率调制的方法克服传输信道自身和海洋环境的不利条件。系统选用单片调制解调芯片MSM7512B对信号进行FSK调制和解调,实现了水下探头和水面控制单元的通信。采用低功耗的MSP430单片机作为运算处理器,软件设计上充分利用其多种低功耗工作模式,降低了系统的功耗。

| Abstract: | A design approach of data transmission system for the expendable seawater temperature measurer is proposed.According to the characteristics of long transmission distance and great waveform distortion,the frequency modulation method was adopted to overcome unfavorable conditions about transmission channel and marine environment.The communication between underwater probe and control unit on water surface was realized by modem chip MSM7512B used in FSK modulation and demodulation of signal.MSP430 single chip microcontroller with low power was chosen as the operational processor.The system power dissipation was reduced through various low power working modes provided by MSP430 in software design. |
