防人身伤害温室卷帘机智能控制器研制

摘要

提出了一种防人身伤害温室卷帘机智能控制器.采用单片机AT89S52作为控制主体,配置水平板靠近卷帘机卷轨边缘,人员卷入卷轨后平板位置随之变动.利用超声波传感器对平板进行实时定位,位置信息输入单片机以判断是否执行紧急制动.兼具每日按时收放帘功能、过温监测功能以及全球移动通信系统(GSM)网络短信通知功能.从硬件和软件介绍了控制系统的组成结构,并制作样机.实验结果验证了方案的有效性.%To avoid personal injury,a new intelligent controller for greenhouse rolling machine is developed.Using MCU chip AT89S52 as the kernel of the system,a fiat plate is placed horizontally close to the edge of the rolling track whose position will be altered when human body get entangled in.Ultrasonic senor is adopted for real-time positioning of the flat plate,location information is collected by MCU to judge whether the emergency brake should be carried out.The controller also possesses the function of daily rolling,over-temperature monitoring and SMS notification through GSM network.The composition and structure of the control system is described from the viewpoint of hardware and software.Experimental results verify the effectiveness of the design.
