Detection System of Ship’s Magnetic Field Signal Based on PNI Magnetic Sensor

摘要:

针对舰船磁场检测这一问题,提出了一种利用 PNI 磁传感器测量的方案,并设计了一套由 STC15 单片机控制的舰船磁场检测系统。 系统由 PNI 磁传感器、STC15 单片机、串口通讯模块、电源分配模块和上位机组成,实现了信号的采集、调理、传输和分析处理的过程。 最后,通过水池船模试验证明了该测量系统能够实现对舰船磁场信号进行检测。

Abstract:

For the issue of ship magnetic field measurement, a method based on PNI magnetic sensor is proposed, and a de- tection system of ship’s magnetic field controlled by STC15 MCU is designed. The system consists of PNI magnetic sensor, STC15 MCU, serial communication module, power distribution module and host computer, which realizes the process of acquisition, pro- cessing, transmitting and analytical processing. Finally, it is verified that the measurement system can detect ship’s magnetic field signal by ship model test in tank.
