Abstract

The invention relates to a multi-keyboard input system, multi-keyboard input equipment, a multi-keyboard input switching device and a control method. The multi-keyboard input switching device comprises a keyboard interface, a host PS / 2 interface, a programmable logic device and a microcontroller; and the microcontroller is used for scanning input information in real time, receiving the scanned input information, receiving the input information sent by external PS / 2 keyboards, decoding the input information of external matrix keyboards, and sending the input information sent by the external PS / 2 keyboards and the decoded input information of the external matrix keyboards to an external host through the programmable logic device. The multi-keyboard input switching device solves the problem that a plurality of standard PS / 2 keyboards and matrix keyboards are simultaneously connected to the host, and has simple structure, maintenance convenience and high cost performance; a main board andan operating system which can be compatible with the standard PS / 2 keyboards can directly use the multi-keyboard input equipment and the multi-keyboard input switching device without loading any drive; and the multi-keyboard input equipment and the multi-keyboard input switching device have small volume and good reliability, and are convenient to install.

Description

technical field [0001] The invention relates to an industrial control computer, more specifically, to a multi-keyboard input system, equipment, switching device and control method. Background technique [0002] In the industrial control industry, sometimes we not only need to use the standard PS / 2 keyboard, but also need a special keyboard for performing special functions, that is, a matrix keyboard customized by the user according to the needs. This kind of keyboard can be seen everywhere in our daily life, such as bank ATMs and hospital monitors, but in industrial sites, we often encounter situations where not only one custom matrix keyboard but multiple matrix keyboards are required. Generally, this kind of keyboard is embedded in the cabinet. Due to the structural requirements, we all want the area of ​​this kind of keyboard to be as small as possible on site, and it should be operated by several separate operators. Due to the structure of the keyboard itself, the keys ...
