摘　　要：为了有效地在水下环境中长期测量海浪水压场信号,研制了基于高精度US10000型压阻式压力传感器和MSP430F2618低功耗单片机的水压场测量系统;针对传感器功耗较大的问题,提出了基于脉冲供电技术的压力传感器供电方式,该方法采用间歇供电的方式使传感器工作,以解决因传感器功耗大而带来的系统功耗较大的问题;最后,对整套系统的功耗进行了测试,并利用海上试验对系统的性能进行了检验,结果表明:该系统总功耗不足15mW,一节3.6V/19Ah型号的锂电池可保证整套系统水下连续工作190余天。Pressure sensor US10000 is widely used in the signal measurement system of the ocean wave hydrodynamic pressure field in view of its high stability, high-precision, and big destruction pressure specialties. In order to ensure the system can measure the ocean wave hydrodynamic pressure field signal in the underwater environment for a long time, a method of pressure sensor power supply was proposed based on pulse power supply technology. And a water pressure field collection system was based on MSP430F2618 by this method. The power consumption of this system is less than 15 mW and one 3.6 V/19 Ah lithium battery can ensure the continuous 190 days＇ work of the system.
