Currently, most rolling doors in malls are manual controlled or wireless controlled in short distance, which requires that the operators must be near the rolling doors. By using GSM technology to upgrade the original rolling door control system, operators can not only control rolling doors remotely by mobile phone, but also can grasp the working state of rolling doors, which greatly improves the management efficiency and security of malls.%目前大多商场卷帘门都是手动开关控制或近距离无线控制，这种控制方式需要工作人员必须在卷帘门附近。运用GSM技术，对原有的卷帘门控制系统进行升级，操作人员通过手机不仅能够远程控制卷帘门，还能实时了解卷帘门的工作状态，大大提高了商场的管理效率和安全。
