基于毫米波雷达的人体运动存在传感器设计

Design of Human Motion Presence Sensor Based on Millimeter Wave Radar

介绍了基于毫米波雷达技术设计的人体运动存在传感器。方案使用PCR脉冲相干毫米波雷达传感器,结合主控MCU完成了雷达数据采集、处理和分析;采用了ZigBee网络的接入本地网关方式,能对人体存在事件进行及时上报,进而能实时完成报警、消息推送到用户或者启动相关的情景模式。重点对系统硬件、外壳结构、软件检测算法等设计要点进行了阐述。

The human motion presence sensor designed based on millimeter wave radar technology is introduced.The PCR pulse coherent millimeter wave radar sensor and main control MCU are used to complete radar data acquisition,processing and algorithm analysis.With the ZigBee network access to the local gateway,it can timely report the human body events and then complete the alarm in real time,and push the message to the user or start the relevant scenario mode.The design key points of system hardware,shell structure and software detection algorithm are expounded.
