大棚卷帘机防越位与走偏系统设计

Design of the anti-offside and deviation system of canopy shutter

我国设施农业面积占世界设施农业总面积80%以上,设施农业主要指温室大棚的利用,温室大棚使用的主要机械装备是大棚卷帘机。定时器或手机短信控制的大棚卷帘机在卷放帘时,人通常不在现场,所以可能出现卷帘越位、走偏等问题。对大棚卷帘机越位与走偏的情况进行了研究,通过霍尔传感器、压力传感器及单片机设计了大棚卷帘机防越位与走偏系统,当大棚卷帘越位或走偏时,传感器发出信号通过单片机处理后控制继电器使大棚卷帘机停止工作,可有效地防止卷帘滚落、电机烧毁、人员受伤等事件的发生。

Facilities agricultural area in China accounted for over 80% of the total area of the world facility agriculture,facilities agriculture mainly refers to the use of greenhouses,greenhouse to use rolling machine is the main mechanical equipment of the greenhouse.Timer or SMS control of greenhouse in volume curtain shutter machine people are usually not in the scene,so the possible shutter offside,such problems as deviate.To deviate the offside and canopy shutter machine was studied,the canopy by hall sensor,pressure sensor and single-chip microcomputer shutter writers offside and partial system,when canopy shutter offside or partial,sensor signal by single chip microcomputer control relay after processing the greenhouses shutter machine to stop working,and can effectively prevent the shutter tumble motor burn injuries.
