The invention provides an all-in-one machine and a method for simultaneously touching an external device and a built-in system. The all-in-one machine comprises a touch frame, a universal serial bus (USB) switch, a built-in personal computer (PC) template, a main board and a microprogrammed control unit (MCU), wherein the touch frame is connected with the USB switch through a USB, the USB switch is connected with the built-in PC template, the main board and an external device through the USB, the MCU is connected with the touch frame through a serial port, and the MCU is connected with the main board through the USB. By the aid of the all-in-one machine and the method for simultaneously touching the external device and the built-in system, time waste caused by recognition of the USB can be prevented, and the touch operation can be conducted immediately after switching is conducted through the USB switch.
Description
technical field [0001] The invention relates to the field of electronic information, in particular to an all-in-one machine and a method for realizing simultaneous touch of an external device and a built-in system in the all-in-one machine. Background technique [0002] Interactive smart tablet, referred to as all-in-one machine, is an integrated device that integrates TV technology, computer technology, touch technology, and audio technology to realize human-computer interaction. It not only has the function of high-definition display of traditional LCD TVs, but also through The built-in computer module is configured so that it also has computing power, and the computer can be controlled through touch technology to obtain a convenient human-computer interactive experience. The all-in-one machine integrates the display functions of TV, built-in PC, and multiple channels such as VGA, HDMI, AV, and YPBPR. Among these multiple channels, the remote control or physical buttons ar...
