Abstract
The invention is applicable to the field of communication technology, and provides an OTG-based (On-The-Go-based) intelligent terminal operation control method and an OTG-based intelligent terminal operation control device. The method includes the following steps: under the condition that the OTG function of an intelligent terminal is switched off, if a universal serial bus (USB) interrupt request is received, then the voltage value of a USB interface is acquired; when the voltage value of the USB interface is within a preset range, the intelligent terminal is charged by an external device connected with the USB interface. The OTG function of the intelligent terminal is switched off by default, the voltage value of the USB interface is acquired when the USB interrupt request is received, the intelligent terminal is charged by the external device connected with the USB interface when the voltage value of the USB interface is within the preset range, consequently, the intelligent terminal is prevented from being always in the OTG mode due to the corrosion of the USB interface, and the intelligent terminal still can be normally charged under the condition that the OTG USB interface is corroded.
