Demonstrator system file protection method and device, storage medium and demonstrator

The invention provides a demonstrator system file protection method and device, a storage medium and a demonstrator. The demonstrator is provided with a main power supply and a wireless power supply module. The system file protection method comprises the steps that whether the main power supply of the demonstrator is powered off abnormally or not is detected; and when it is detected that the main power supply is powered off abnormally, the demonstrator is powered on through the wireless power supply module, so that the demonstrator is not powered off, and system files are stored. According to the above scheme, the reliability of the industrial demonstrator can be effectively improved. 本发明提供一种示教器系统文件保护方法、装置、存储介质及示教器。所述示教器具有主供电源和无线供电模块，所述系统文件保护方法，包括：检测所述示教器的主供电源是否异常断电；当检测到所述主供电源异常断电时，通过所述无线供电模块给所述示教器供电，使所述示教器不掉电，以进行系统文件保存。根据本发明的上述方案，能有效提高工业示教器的可靠性。
