摘　　要：全自动卸砖打包机已成为砖瓦建材生产线的标准配置,作业期间闲杂人员非法进入工作区域极易引发安全事故。监测到非法人员进入危险区域后自动报警,并在紧急情况下自动停机处理已成为卸砖打包机升级改造的重点。现有基于红外传感器检测或超宽带技术建立虚拟电子围栏的方法存在检测精度低、预警方式单一以及事故发生后责任难以界定等问题。为此,研发一种基于单目视觉与目标检测算法YOLOv5的全自动卸砖打包机工作区非法入侵检测系统。该系统由摄像头、单片机、报警器、继电器以及控制软件等组成,采用单目摄像头进行图像获取与定位测距,利用目标检测算法YOLOv5进行目标检测与识别;检测到闲杂人员非法进入工作区时会发送相应指令给单片机,由控制传感器进行报警、停机等处理。仿真实验结果表明,该系统能有效完成拍照、定位测距、检测识别、告警、紧急停机等功能,准确度达到94%以上,与现有方法相比功能更强、成本更低,可有效解决工作区域内闲杂人员非法进入等安全问题。The fully automatic brick unloading and packaging machine has become a standard configuration for brick and tile building materi-als production lines.During operation,unauthorized entry into the work area by idle personnel can easily lead to safety accidents.The automat-ic alarm upon detecting illegal personnel entering the dangerous area and the automatic shutdown in emergency situations have become the fo-cus of upgrading and renovating the brick unloading and packaging machine.The existing methods for establishing virtual electronic fences based on infrared sensor detection or ultra wideband technology have problems such as low detection accuracy,single warning methods,and difficulty in defining responsibilities after accidents occur.To this end,a fully automatic brick unloading and packaging machine work area il-legal intrusion detection system based on monocular vision and object detection algorithm YOLOv5 has been developed.The system consists of a camera,a microcontroller,an alarm,a relay,and control software.It uses a monocular camera for image acquisition,positioning,and dis-tance measurement,and uses the object detection algorithm YOLOv5 for object detection and recognition;When it is detected that unauthor-ized personnel have entered the work area,corresponding instructions will be sent to the microcontroller,which will be controlled by the sen-sor for alarm,shutdown,and other processing.The simulation experiment results show that the system can effectively complete functions such as photography,positioning and distance measurement,detection and recognition,alarm,emergency shutdown,etc.,with an accuracy of over 94%.Compared with existing methods,it has stronger functions and lower costs,and can effectively solve security problems such as unau-thorized entry of idle personnel in the work area.
