随着经济的不断发展和科学技术的不断进步，蔬菜大棚的数量越来越多，而收放蔬菜大棚的草帘是一项繁重的工作，有许多蔬菜大棚已使用电动卷帘机收放蔬菜大棚的草帘，但其操纵必须有人站在寒冷的棚外操作，且在工作过程中操作人员不得离开，同时大棚卷帘机卷死人事故也频繁的发生，因此这种卷帘机的使用方式方便、而且有危险性，满足不了现代农业高效率、自动化和安全方便快捷的要求。
With the continuous development of economy and the progress of science and technology, the number of vegetable greenhouses is increasing. It is a heavy work to put the curtain in vegetable greenhouses. Many vegetable greenhouses have used electric curtain rolling machine to put the curtain in vegetable greenhouses, but its operation must be operated by someone standing outside the cold greenhouse. Operators are not allowed to leave during the process, and accidents of curtain rollers in greenhouses occur frequently. Therefore, the use of curtain rollers is convenient and dangerous, which can not meet the requirements of high efficiency, automation and safety in modern agriculture.
现在的市面卷帘机遥控器都是不能跟倒顺开关并联使用的，而且没有保护措施，如果电机坏,控制器就烧毁，同时现在市面的遥控器都是手割码方式，这样极易重码有可能100栋大棚一个客户遥控的时候就会把同区别家的大棚卷起很容易出事故。
Nowadays, the remote controllers of market curtain rolling machine can not be used in parallel with the reverse switch, and there are no protective measures. If the motor is damaged, the controller will be burned down. At the same time, the remote controllers in the market are all hand-cut codes, so it is very easy to weigh 100 greenhouses and roll up the same greenhouse when one customer remotely controls it. It's very accident prone.
