摘要
目前传统视频监控系统投资较大,不能及时发现偷盗情况并报警且不能进行智能跟踪。该项目运用超声波定位技术,在单片机指令信号的作用下向位置固定的应答器发射同频率的红外信号,应答器在收到红外信号后向主测距器发射超声波信号,得到主测距器与各个应答器之间的距离。根据相关计算确定出被测物体所在的二维坐标系下的位置。运用该技术在被测物体上安装超声波传感器,实现全面智能监控人员活动情况,发现偷盗情况并进行智能跟踪,并及时报警的功能。
Traditional video monitoring system can not find out the stealing situation in time and can not be intelligent tracking. The project uses ultrasonic positioning techniques to transmit an infrared signal of the same frequency to the fixed location transponder. The transponder transmits ultrasonic signals to the primary ranging. It obtains the distance between the respective transponder. The position is defined in accordance with the relevant calculations. Ultrasonic sensors are installed in the cart, which can monitor staff activities intelligently, find out and track the theft, and alarm timely.
