Embodiment Construction

[0023] The invention provides a method for realizing hot-plugging of an input interface. The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings to make it easier to understand and grasp.

[0024] The implementation method of PS / 2 interface hot swap in this case mainly uses the single-chip system to complete the equipment registration in the early stage, the back-end realizes the long-distance transmission of PS / 2 signals through the signal driver, and the power supply system of the single-chip computer directly uses the power supply of the PS / 2 port of the host computer Therefore, the single-chip microcomputer is required to have extremely low power consumption, and at the same time, in order to realize the hot swap of at least 10 PS / 2 interfaces, the single-chip microcomputer is required to have a certain number of I / Os.

[0025] In specific embodiments, such as figure 1 As shown, the PS / 2 interface circ...

Abstract

The invention discloses a hot plug implementation method for an input interface. The system comprises an STC single chip microcomputer, PS / 2 equipment, a panel switch, a plurality of HOST end equipment and a driver and switcher connected with the HOST end equipment, the STC single chip microcomputer is in communication connection with the PS / 2 equipment, the panel switch and the driver and switcher, and the hot plug implementation method comprises the steps of equipment registration and arbitrary communication establishment. According to the invention, the STC single-chip microcomputer is adopted; compared with the prior art, the single-chip microcomputer has the advantages of being good in expansibility, flexible in design and stable in performance, the single-chip microcomputer pin can be selected according to the number of PS / 2 computers which are externally hung, PS / 2 equipment registration among multiple computers can be achieved after the signal driver is additionally arranged, and the PS / 2 mouse and the keyboard can be switched in a hot plug mode subsequently to control any computer. The application range of PS / 2 equipment is widened, and convenience is brought to remote centralized control.

Description

technical field [0001] The invention relates to a method for realizing hot-plugging of a PS / 2 interface, and belongs to the technical field of hot-plugging of a PS / 2 interface. Background technique [0002] The PS / 2 interface is an input interface, not a transmission interface. Therefore, the PS2 port has no concept of transmission rate at all, only scan rate. In Windows environment, the default sampling rate of ps / 2 mouse is 60 times / sec, and the sampling rate of USB mouse is 120 times / sec. A higher sample rate can theoretically improve the accuracy of mouse movements. [0003] The PS / 2 interface first appeared on IBM's PS / 2 computer, from which it got its name. It is a dedicated interface for mouse and keyboard, a 6-pin circular interface commonly used on older computers. It has simple physical connection and two-way synchronous serial communication. The only disadvantage is that it does not support hot swapping, that is, when the computer starts up before the PS / 2 dev...
