投影设备10上电后，开机启动模块11接收到输入操作而输出启动信号至检测模组121，检测模组121在检测到启动信号后将所述启动信号输出至控制模组123，控制模组123输出对应的警示信号至驱动控制电路133，驱动控制电路133则将警示用语输出至显示屏131进行显示。
同时，检测模组121在检测到启动信号后将所述启动信号输出至控制模组123，控制模组123输出对应的控制信号至投影模块14，投影模块14则将自数据传输模组15接收到的待投影显示的图像数据信息输出至光机模块142，通过光源模块141的配合，将待投影显示的图像数据信息利用投影镜头进行投影显示。
当待投影显示的图像数据信息投影显示完毕，且开机启动模块11接收到输入操作而输出关闭信号时，检测模组121在检测到关闭信号后将所述关闭信号输出至控制模组123，控制模组123输出对应的停止警示信号至驱动控制电路133，驱动控制电路133则停止将所述警示用语的图像数据信息输出至显示屏131，换句话说，警示模块13停止显示警示用语，另外，投影模块14停止自数据传输模组15接收图像数据信息，也即是投影模块14停止进行图像投影显示。
所述投影设备10在投影设备上电开启工作时警示模块13方才开始工作，并且在投影设备10停止工作后，警示模块13停止工作，换言之，也即是投影设备10中的投影模块14进行投影光线的输出时警示模块13才开始显示工作，而投影模块14停止出射光线后，警示模块13则停止警示用语的显示，警示用语是随着投影设备10与图像显示同步，提高了警示用语显示警示效率的同时。较大的提高警示用语的显示效果与效率，同时提高了投射设备的使用安全性，保证了使用者的健康。
