Embodiment Construction

[0069] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0070] Embodiments of the present invention provide a keyboard data transmission method and device, which are used to solve the problem of repeated keyboard data transmission in the prior art due to unstable network and high message delay. Wherein, the method and the device are based on the same inventive concept, and since the principles of the method and the device to solve problems are similar, the implementation of the device and the...

Abstract

The invention discloses a keyboard data transmission method and device which are used for solving the problem that in the prior art, due to the situations that network is not stable and the message delay is long, keyboard data are repeatedly transmitted. The method includes the steps that when a key on a keyboard of a client side is detected to be pressed, key information used for indicating that the key is pressed is generated and sent to a server, and the key information carries the key value corresponding to the pressed key; before the key is detected to be released, when the time interval between the current time to the time when the key information is sent last time exceeds the preset duration threshold value in each time of judgment, the generated key information stops being sent to the server again till the key is detected to be released; the preset duration threshold value is the experience duration value needed when the key is recognized to be normally pressed.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a keyboard data transmission method and device. Background technique [0002] Remote KVM (abbreviation of Key, Vedio and Mouse, keyboard, mouse and monitor) technology is KVM Over IP technology, which encapsulates the video data of the server into IP data packets and transmits them to the remote client. The original KVM data is displayed, so that the client can achieve the purpose of monitoring. The client returns the mouse and keyboard data operated by the user to the server in the same way, thereby completing the data interaction function. [0003] Existing KVM transmits keyboard data by simulating the local hardware keyboard, and transmitting a complete key needs to rely on two messages, one is the press message of the key value, and the other is the release message of the key value. The remote server determines the number of characters input by the user according to t...
