Drive-free quick response input device based on intelligent tablet computer

Abstract

The invention discloses a drive-free quick response input device based on an intelligent tablet computer and a method for connecting an Android tablet computer as a ps2 general keyboard into a computer system. The device and the method are used for solving the problem that the existing scheme utilizing an intelligent tablet computer system as an input device is low in response speed, the effect of plug and play cannot be achieved in a first-time use process, and large intelligent devices are often free of a wireless network accessing function. The device comprises a graphic interface, a human-computer interaction application program interface (API) and an input / output (I / O) mapping middle piece. The effect that an android embedded device is connected into the computer as a ps2 keyboard is achieved by adding a simple hardware circuit and combining corresponding software, so that relevant requirements of the large intelligent devices for flexible input means, friendly interaction modes, high response speed and good universality of the input device are met.

Description

technical field [0001] The invention relates to a technology for connecting a smart tablet to a computer as an external input device. The computer terminal does not need any driver and software support. Under any operating system, the computer terminal regards the device as an actual physical universal input device. In particular, it relates to a technology for connecting an Android tablet computer to a computer system as a ps2 universal keyboard. Background technique [0002] At present, large-scale digital intelligent equipment is widely used in the production and life of today's society, such as large-scale medical detection and treatment equipment, digital machine tools, assembly line robotic arms, etc. Due to the long time required for most of its development and the aging of its input and output equipment, most of them still use old-fashioned mechanical keyboard. In the process of updating these large smart devices, due to the complexity of their own con...
