Dual Power Automatic Switch Device Design

In this paper, we designed dual power automatic switch device, which is based on one of microcontrollers named STM8S105K4, and objected to non_contract electric switch. The device makes fully use of microcontroller's inner resources, which has ability to push_button, display, monitoring, switch, communication. Tests have proved that the device has the advantage of reliable to work, stable performance and high reliability.
