Problems solved by technology

[0003] Now, under the Linux (Fedora14) diskless system used by the betting terminal, after the kernel sleeps, the system cannot be woken up through the USB keyboard input device. To end the sleep state, you can only use the PS2 keyboard to wake it up or restart it through "POWER ON" Press the key to restart the system, the computer will have redundant consumption during the startup process, and at the same time, it is related to the requirements of the ten-ring certification that the host computer meets the standard "HJ / T313-2006 Environmental Labeling Product Technical Requirements for Microcomputers and Displays" and items 3 and 5. The state of energy saving does not conform to the relevant provisions of the energy consumption index

Embodiment Construction

[0010] The present invention will be described in detail below with reference to the drawings and specific embodiments.

[0011] As shown in the figure, by writing a piece of code to patch the Linux (Fedora14) diskless system, the betting terminal will be awakened and loaded into the kernel when the betting terminal is produced. When the betting terminal in the sales hall is idle for a period of time, it will automatically enter the sleep state ; When the lottery player needs to use the terminal, he can wake it up through the USB keyboard without restarting the betting terminal; the terminal can operate normally after waking up.

[0012] The above implementation is only an example of the invention, not intended to limit the implementation of the invention and the scope of rights. All equivalent changes and modifications made according to the content described in the scope of protection of the invention application should be included in the invention application. Within range.

Abstract

The invention belongs the technical field of lottery machines, and relates to a USB keyboard input device of a Linux diskless system, in particular to a method for waking up the Linux diskless system through the USB keyboard input device. The method includes the step of patching the Linux (Fedora14) diskless system by editing a piece of code to wake up the Linux (Fedora14) diskless system through the USB keyboard. With the method of patching the Linux (Fedora14) diskless system by editing the piece of code to wake up the Linux (Fedora14) diskless system through the USB keyboard input device, system restart is not needed for waking up a dormant state, and therefore energy consumption can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of lottery machines, and relates to a Linux diskless system USB keyboard input device, in particular to a method for waking up a Linux diskless system USB keyboard input device. Background technique [0002] With the rapid development of computer technology, the USB protocol has transitioned from 1.1 to 2.0, and then developed to 3.0 today. Its most important indicator of device transmission speed has also been greatly improved, and its application in the computer field has also increased. Wider. As a hot spot in the field of computers and embedded systems in the past few years, USB has promoted the rapid development of computer peripherals and has occupied the PC and peripheral market. At present, the video-type lottery operation platform and betting terminal of the welfare lottery will also be widely used in USB keyboard input devices in response to the requirements of market development. [0003] Now, under th...
