Keyboard matched with multiple receiving devices

Abstract

The invention relates to a keyboard matched with multiple receiving devices, which comprises a keyboard input area, a first wireless communication module, a second wireless communication module, a wired transmission communication module, a fling-cut switch, a selection controller, a power supply selection module and an attitude detection receiving module; the attitude detection receiving module receives an attitude detected by an external attitude detection module and transmits the attitude to the selection controller, and the selection controller analyzes the attitude, outputs a first selection control instruction, transmits the first selection control instruction to the fling-cut switch, controls the fling-cut switch to be selectively connected with one of the first wireless communication module, the second wireless communication module and the wired transmission communication module; the working frequencies of the first wireless communication module and the second wireless communication module are different; and the power supply selection module is used for supplying power to at least one of the first wireless communication module, the second wireless communication module and the wired transmission communication module according to a second selection control instruction of the selection controller.

Description

technical field [0001] The invention relates to the technical field of intelligent control devices, in particular to a keyboard matched with multiple receiving devices. Background technique [0002] In the prior art, in many cases, one keyboard controls one receiving device. With the improvement of technology, a keyboard is controlled by a mechanical switch to switch between multiple receiving devices. When switching, it is necessary to manually toggle the mechanical switch every time, which is very convenient when multiple receiving devices need to be controlled at the same time; in the existing patented technology, there is also a device for automatically switching the receiving device controlled by the keyboard, such as patent application CN201610389693. In the technical solution disclosed in 7, the actual state of the user is obtained by the image acquisition unit, and the receiver is automatically switched according to the actual state of the user, which improves the sw...

Problems solved by technology

[0002] In the prior art, in many cases, one keyboard controls one receiving device. With the improvement of technology, a keyboard is controlled by a mechanical switch to switch between multiple receiving devices. When switching, it is necessary to manually toggle the mechanical switch every time, which is very convenient when multiple receiving devices need to be controlled at the same time; in the existing patented technology, there is also a device for automatically switching the receiving device controlled by the keyboard, such as patent application CN201610389693. In the technical solution disclosed in 7, the actual state of the user is obtained by the image acquisition unit, and the receiver is automatically switched according to the actual state of the user, which improves the switching efficiency of the keyboard control to a certain extent and improves the user experience. However, the The patent application uses one transmitter corresponding to multiple receivers. By changing the frequency of the transmitter to change the corresponding connector according to the user's status, this method of switching frequency needs to temporarily adjust the frequency, and there is a certain period of time when adjusting the frequency Delay

[0003] For example, the patent application CN201110067638.3 also switches the receiving device by switching the frequency. Although the switching between the pre-stored first operating frequency and the second operating frequency in this technical solution can quickly respond to the frequency switching to a certain extent, it is still through A sending module performs frequency switching. During frequency switching, there is a handover device from the first working frequency to the second working frequency. This handover device may have two operating frequencies in the propagation space, resulting in bugs in the keyboard control. Causes a defect in switching timeliness

The above two devices can only be controlled wirelessly, and cannot achieve wireless and wired compatible control. When the keyboard control object is a notebook and a desktop computer, it cannot be effectively controlled

[0004] In the prior art, there is no better control of the timeliness of keyboard switching, nor is there a better setting when the keyboard is connected, and it is necessary to temporarily analyze the user's perspective or posture. This is an important difficulty in improving user experience
