基于地磁与红外双模探测的海洋浮标预警系统设计

Design of an Ocean Buoy Auto-Warning System Based on Geomagnetic-Infrared Detection

设计了一种基于地磁检测与红外感应相结合、可对浮标周围异常目标进行探测和预警的控制系统。系统采用芯片级的微型磁感线圈,以及高集成度、低功耗的数据采集与总线技术,通过探测船体磁性对地磁场的扰动,监测船舶对浮标的靠近;采用芯片级的热释电红外传感器,通过探测人体红外辐射,监测浮标在正常工作期间未知人员的入侵。系统的预警采用声光报警和图像远程传输相结合的方式,现场采集的图像数据经过压缩编码后通过无线数传电台发送至远程岸基监测站,实现海洋浮标的远程预警与现场取证功能。

This paper designs a kind of anomaly target detection and warning system based on geomagnetic detection combined with infrared induction technology. The system adopts chip level of micro magnetic induction coil, as well as the data acquisition and bus technology featured by high integration and low power consumption, so as to realize monitoring ship motion around buoy by detecting the ship magnetic disturbance of the geomagnetic field. The design uses chip level of pyroelectric infrared sensor to monitor invaded unknown persons during normal work by detecting the infrared radiation of human body. The early warning system adopts the combination of sound and light alarm and remote image transmission. The acquired image data on site are sent to the remote monitoring station via wireless digital shore-based station after compression coding, in order to achieve the function of ocean buoy remote warning and scene evidence obtaining.
