Description

Technical Field

[0001] The present invention relates to the technical field of computer peripherals, and more particularly to a keyboard and mouse backlight linkage method, device, computer equipment and medium. Background Art

[0002] In the field of modern computer input devices, keyboards and mice are essential tools for users to interact with computers, and optimizing their functionality and user experience has always been a key research and development focus. Backlighting has also become a common feature of keyboards and mice. Backlighting not only helps users more clearly identify keyboard keys and mouse outlines in dimly lit environments, improving operational accuracy, but also adds a personalized and aesthetic element to the product, meeting the diverse needs of different users for device appearance. For example, backlighting can significantly enhance user convenience when working at night or gaming.

[0003] However, the backlight control methods for most keyboards and mice currently on the market have certain limitations. Common control methods include manually turning the backlight on or off using specific key combinations, or setting several preset modes such as constant on and flashing, which the user needs to manually switch between. This traditional control method lacks intelligence and connectivity, and cannot automatically respond to actual usage scenarios. For example, when a user uses a device in a well-lit environment and then enters a darker environment, they often need to manually turn on the backlight. This process may interrupt the user's operating process and cause inconvenience. Conversely, when the light becomes brighter, users may easily forget to turn off the backlight, resulting in energy waste.

[0004] Furthermore, existing keyboard and mouse backlights are typically controlled independently, lacking an effective synchronization mechanism. This can lead to inconsistent lighting conditions between the two during use, impacting the overall visual experience and user experience. For example, in games or personalized scenarios that require coordinated lighting effects, the keyboard and mouse backlights may not light up or turn off synchronously, or their color, brightness, and other parameters may not be consistent, disrupting overall coordination.

[0005] Although there is currently a way to synchronously control the backlight of the mouse and keyboard through the computer's control chip, this method is relatively rigid and requires the user to enter the corresponding setting page to make settings. It is not only inconvenient to operate, but also cannot automatically respond according to actual conditions. Summary of the Invention

[0006] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a method, device, computer equipment and medium for backlight linkage of a keyboard and a mouse.

[0007] To achieve the above object, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a backlight linkage method for a keyboard and a mouse. The keyboard is wirelessly communicatively connected to the mouse. The keyboard is provided with a first induction coil and a first backlight, and the mouse is provided with a second induction coil and a second backlight. The method includes:

[0009] Monitoring the first induction coil and the second induction coil;

[0010] When the first backlight and the second backlight are in the sleep state, if an induction trigger object is detected within the induction range of the first induction coil or the second induction coil, the first backlight and the second backlight will be synchronously awakened to switch from the sleep state to the lit state.

[0011] Further, the method further includes:

[0012] When the first backlight and the second backlight are in the lit state, if no induction trigger object is detected within the induction range of the first induction coil or the second induction coil for a duration exceeding a set time, the first backlight and the second backlight will switch from the lit state to the sleep state.

[0013] Further, when the first backlight and the second backlight are in the lit state, the backlight colors of the first backlight and the second backlight remain the same.

[0014] Further, when the first backlight and the second backlight are in the lit state, the backlight color change frequencies of the first backlight and the second backlight remain the same.

[0015] Further, when both the first backlight and the second backlight are in a non-sleep state, if one of the first backlight and the second backlight is not lit, the lit backlight emits a maintenance prompt message.

[0016] Further, the maintenance prompt message is a light prompt emitted by the lit backlight.

[0017] Further, the light prompt is a high-speed flicker at a set frequency.

[0018] In a second aspect, the present invention further provides a backlight linkage device for a keyboard and a mouse. The keyboard is wirelessly communicatively connected to the mouse. The keyboard is provided with a first induction coil and a first backlight, and the mouse is provided with a second induction coil and a second backlight. The device includes:

[0019] A monitoring unit for monitoring the first induction coil and the second induction coil;

[0020] The synchronous lighting unit is used to synchronously wake up the first backlight and the second backlight when they are in the sleep state if an induction trigger object is detected within the induction range of the first induction coil or the second induction coil, so as to switch from the sleep state to the lighting state.

[0021] In a third aspect, the present invention also provides a computer device, including a memory, a processor, and a computer program stored on the memory and executable on the processor. When the processor executes the computer program, the backlight linkage method of the keyboard and mouse as described above is implemented.

[0022] In a fourth aspect, the present invention also provides a computer-readable storage medium. The storage medium stores a computer program, and the computer program includes program instructions. When the program instructions are executed by a processor, the processor is caused to execute the backlight linkage method of the keyboard and mouse as described above.

[0023] The beneficial effects of the present invention compared with the prior art are as follows: For the backlight linkage method of the keyboard and mouse, the keyboard and the mouse are wirelessly communicatively connected. The keyboard is provided with a first induction coil and a first backlight, and the mouse is provided with a second induction coil and a second backlight. The method includes: monitoring the first induction coil and the second induction coil; when the first backlight and the second backlight are in the sleep state, if an induction trigger object is detected within the induction range of the first induction coil or the second induction coil, the first backlight and the second backlight will be synchronously woken up to switch from the sleep state to the lighting state. The present invention can automatically control the backlight state based on the actual usage scenario of the user. When an induction trigger object (such as the user's hand approaching) is detected by either the keyboard or the mouse, the two-way backlights can be synchronously woken up without manual operation, solving the problem that the traditional manual control method needs to interrupt the operation process, and avoiding the problem of inconsistent light states (such as the keyboard being lit while the mouse is not lit) that may occur in the traditional independent control mode. In addition, when neither of them detects a trigger object, they will synchronously enter the sleep state, reducing the ineffective standby power consumption compared with the independent control mode.

As used in the specification of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are intended to include the plural forms.

[0033] It should be further understood that the term " / and / " used in the specification of the present invention and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0034] The embodiments of the present invention provide a backlight linkage method for a keyboard and a mouse. The keyboard is wirelessly communicatively connected to the mouse. The keyboard is provided with a first induction coil and a first backlight lamp, and the mouse is provided with a second induction coil and a second backlight lamp.

[0035] Both the keyboard and the mouse are built-in with an MCU, such as STM32F103, and the keyboard and the mouse communicate via the Bluetooth protocol. Both the first induction coil and the second induction coil adopt micro planar spiral coils. The first induction coil is built into the keyboard housing and arranged around the keys of the keyboard. The second induction coil is built into the mouse housing and arranged around the contour of the mouse. The first backlight and the second backlight are each connected to the MCU. The first backlight and the second backlight use WS2812B programmable colorful LEDs and receive the RGB data of the MCU through a single bus. Both the first induction coil and the second induction coil are connected to an LC oscillation circuit (such as an oscillator composed of an NE555 timer), and it is judged whether a metal object (such as a human finger) is approaching by detecting the inductance change of the first induction coil and the second induction coil. When the induction trigger object (such as a human finger) enters the coil induction range, the human equivalent capacitance is coupled to the coil, resulting in a shift in the resonant frequency of the LC circuit. The frequency change is converted into a voltage signal and input to the ADC pin of the MCU, and the MCU controls the first backlight and the second backlight.

[0036] Such as Figure 1 As shown, the backlight linkage method for the keyboard and the mouse includes the following steps: S10 - S20.

[0037] S10. Monitor the first induction coil and the second induction coil.

[0038] The MCU of the keyboard samples the output voltage V1 of the oscillation circuit of the first induction coil at a frequency of 100 Hz. When the output voltage V1 of 5 consecutive sampling points exceeds the trigger threshold Vth1 (such as 2.5 V), it is determined that the first induction coil has detected the induction trigger object. Similarly, the MCU of the mouse samples the output voltage V2 of the oscillation circuit of the second induction coil at a frequency of 50 Hz. When the output voltage V2 of 3 consecutive sampling points exceeds the trigger threshold Vth2 (such as 2.3 V), it is determined that the second induction coil has detected the induction trigger object.

[0039] S20. When the first backlight and the second backlight are in the sleep state, if an induction trigger object is detected within the induction range of the first induction coil or the second induction coil, the first backlight and the second backlight will be synchronously awakened to switch from the sleep state to the lit state.

[0040] When the backlights of the keyboard and the mouse are in the sleep state (i.e., both the first backlight and the second backlight are turned off and the MCU enters the low-power mode). If the keyboard detects the triggering of the first induction coil (such as a user's finger approaching the key area), the MCU immediately exits the low-power mode, generates a wake-up instruction frame, and the first backlight is turned on. After the mouse receives the wake-up instruction, it wakes up the second backlight through the MCU. In this way, the first backlight and the second backlight are lit synchronously. Similarly, if the mouse detects the triggering of the second induction coil (such as a user's finger approaching the key area), the MCU immediately exits the low-power mode, generates a wake-up instruction frame, and the second backlight is turned on. After the keyboard receives the wake-up instruction, it wakes up the first backlight through the MCU. In this way, the first backlight and the second backlight are lit synchronously.

[0041] As Figure 2 shown, in an embodiment, the backlight linkage method for the keyboard and the mouse further includes the following steps: S30.

[0042] S30. When the first backlight and the second backlight are in the lit state, if no induction trigger object is detected within the induction range of the first induction coil or the second induction coil for a duration exceeding the set time, the first backlight and the second backlight will switch from the lit state to the sleep state. The set time can be set according to requirements, for example, set to 30 seconds or 60 seconds.

[0043] The keyboard and the mouse each have an independent timer Timer_K and Timer_M, which start timing when the trigger object is detected to disappear. If Timer_K > T and Timer_M > T (synchronize the timing values of both parties through wireless instructions), it is determined that "no trigger object has been detected for a duration exceeding the set time". At this time, the MCU sends a sleep instruction to the mouse and the keyboard. After the mouse and the keyboard receive the instruction, they synchronously turn off the first backlight and the second backlight.

[0044] In an embodiment, when the first backlight and the second backlight are in the lit state, the backlight colors of the first backlight and the second backlight are the same.

[0045] Specifically, the MCU of the keyboard and the MCU of the mouse both output a single-bus signal through the GPIO pin, and the signal frequency is uniformly 800 kHz. Both the keyboard MCU and the mouse MCU have a built-in global color register. For example, when the user sets the color of the backlight to red, the MCU of the keyboard updates the global color register to [255, 0, 0] and synchronizes it to the mouse through a wireless instruction, or when the user sets the color of the backlight to red, the MCU of the mouse updates the global color register to [255, 0, 0] and synchronizes it to the keyboard through a wireless instruction.

[0046] In one embodiment, when the first backlight and the second backlight are in the lit state, the backlight color change frequencies of the first backlight and the second backlight remain the same.

[0047] Both the keyboard and the mouse are equipped with a 32.768 kHz high-precision crystal oscillator (such as Epson TG-5035CA, with an error of ±20 ppm) to provide a reference clock signal for the MCU. Clock synchronization is achieved in the following way:

[0048] The MCU of the keyboard serves as the master clock source and sends a clock calibration packet (including the crystal oscillator count value) to the mouse via a wireless instruction every second; after receiving the calibration packet, the MCU of the mouse adjusts the value of the internal timer register to ensure that the clock deviation between the two sides is < 500 μs. The parameters related to the color change frequency (such as the fade period, blink frequency) are all based on the timer timing to ensure that the frequency calculation benchmarks are consistent.

[0049] In one embodiment, when both the first backlight and the second backlight are in the non-sleep state, if one of the first backlight and the second backlight is not lit, the lit backlight emits a maintenance prompt message. The maintenance prompt message is a light prompt emitted by the lit backlight. The light prompt is a high-speed blink according to a set frequency.

[0050] When in the non-sleep state, if the MCU of the keyboard detects that the first backlight is lit normally, but obtains the status of the second backlight fed back by the mouse via a wireless instruction as "not activated", it indicates that the second backlight has a fault. At this time, the first backlight blinks at a high speed according to a set frequency (such as a 5 Hz high-speed blink) to remind the user. Similarly, if the MCU of the mouse detects that the second backlight is lit normally, but obtains the status of the first backlight fed back by the keyboard via a wireless instruction as "not activated", it indicates that the first backlight has a fault. At this time, the second backlight blinks at a high speed according to a set frequency (such as a 5 Hz high-speed blink) to remind the user.

[0051] In summary, the present invention can automatically control the backlight state based on the actual usage scenario of the user. When either the keyboard or the mouse detects an induction trigger object (such as the user's hand approaching), the two-way backlights can be synchronously awakened without manual operation, solving the problem that the traditional manual control method requires interrupting the operation process, and avoiding the problem of inconsistent light states (such as the keyboard being lit while the mouse is not lit) that may occur in the traditional independent control mode. In addition, when neither of them detects the trigger object, they synchronously enter the sleep state, which can reduce the invalid standby power consumption compared to the independent control mode.

[0052] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution is prior or subsequent. The execution order of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
