Description

Technical Field

[0001] This invention relates to the field of smart home control technology, and more specifically, to a remote control method, control system, and control device. Background Technology

[0002] With the widespread adoption of smart homes and IoT devices, remote controls, as a crucial human-computer interaction interface, are becoming increasingly complex, often integrating displays, sensors, and other components, leading to increased power consumption. To extend battery life, remote controls typically feature low-power modes (such as deep sleep mode), disabling most functions during non-use periods to save energy. Currently, waking up a remote control in low-power mode generally relies on physical buttons. This results in an awkward situation where, upon picking up the remote, the device is not ready: because the remote is still in sleep mode, the first button press is ineffective or delayed, leading to a poor user experience. Furthermore, even solutions that eliminate the need for buttons to wake the remote mostly only perform the "wake-up" process and do not automatically connect the device. Users still need to connect the controlled device via buttons, failing to achieve seamless, ready-to-use control.

[0003] Therefore, how to design a remote control method that can intelligently sense user intent and achieve touch-to-wake and wake-to-connect is an urgent problem to be solved. Summary of the Invention

[0004] The present invention aims to at least solve the problem in the related art where the remote control response delay prevents it from being used immediately upon picking it up.

[0005] Therefore, a first aspect of the present invention provides a remote control method.

[0006] A second aspect of the present invention provides a remote control control system.

[0007] A third aspect of the present invention provides a remote control device.

[0008] In view of this, the first aspect of the present invention provides a remote control method, comprising: detecting contact between a human body and the remote control when the remote control is in a low power mode; in response to detecting contact, exiting the low power mode, entering an active mode, and simultaneously automatically establishing a communication connection with the controlled device.

[0009] According to the remote control method provided by this invention, when the remote control is in low-power mode, it operates with extremely low power consumption and continuously detects whether a human body is in contact with it. Once contact is detected, the remote control immediately responds, exiting the low-power mode and entering the full-function active mode. Simultaneously, it automatically establishes a communication connection with the controlled device. It is understood that the remote control normally only operates the human contact detection function in low-power mode to maintain extremely low power consumption. When a human contact event is detected, the remote control uses this as a wake-up signal and immediately executes three consecutive actions: exiting the low-power mode, switching to the full-function active mode, and simultaneously initiating the communication connection establishment process with the controlled device. This design allows the wake-up ready process of the remote control to overlap in time with the user's natural action of picking up the remote control. The user does not need to perform a special wake-up operation; the remote control has already completed function activation and communication preparation when the user picks it up, thus achieving a zero-delay control response that is ready upon contact. Since the communication connection is established automatically and synchronously when entering activation mode, the communication link between the remote control and the device is ready the moment the user picks up the remote control. The user can directly trigger the function keys to operate, which eliminates the steps of waiting for connection or manually establishing connection after waking up in the traditional way, and brings a seamless control experience that can be used immediately after picking up the device.

[0010] In some embodiments, optionally, after exiting the low-power mode and entering the activation mode in response to detecting contact, and simultaneously automatically establishing a communication connection with the controlled device, the method further includes: in response to triggering a function key on the remote control, sending the function command corresponding to the function key to the controlled device through the communication connection; and in response to detecting that the human body has lost contact with the remote control, exiting the activation mode and entering the low-power mode.

[0011] In these embodiments, in active mode, when a user triggers any function button on the remote control, the remote control generates a function command corresponding to that button and sends the command to the controlled device via the established communication connection to execute the corresponding operation. Finally, when the remote control detects that the human body has disconnected from it, it responds again, automatically exiting active mode and re-entering low-power mode. When the remote control detects that the human body has disconnected, the system determines that use is complete, automatically exits active mode, and returns to low-power mode. This mode management, which uses the user's physical contact as a switch, ensures that the remote control immediately shuts off power to most functional circuits after being removed from the user's hand, minimizing unnecessary standby power consumption and effectively reducing the overall energy consumption of the remote control, significantly extending the battery life after a single charge or battery replacement.

[0012] In some embodiments, optionally, in the activation mode, after the function instruction corresponding to the function key is sent to the controlled device via a communication connection in response to the triggering of the function key on the remote control, the method further includes: displaying the function instruction on the display screen of the remote control; receiving the execution result of the function instruction from the controlled device; and displaying the execution result on the display screen.

[0013] In these embodiments, when the remote control is in active mode and sends a function command to the controlled device in response to a function button press, the remote control further executes a closed-loop feedback process. Specifically, simultaneously with or immediately after sending the function command via the communication connection, the remote control immediately displays the relevant indication of the function command on its built-in display screen, such as indicating in text, icon, or code form that the currently sent command is "volume up" or "channel switch". Subsequently, the remote control receives the execution result of the function command from the controlled device. The execution result can be a confirmation signal of successful operation or updated device status data after execution. The remote control finally updates and displays this execution result on the display screen. For example, after the user presses the volume up button, the display screen first displays a "volume +" prompt, and then receives and displays "volume adjusted to 25". The effect of this process is that it provides instant, visual local confirmation and remote result feedback for each user control operation. Displaying the sent function command on the remote control's display screen allows the user to immediately confirm that the remote control has correctly responded to their button operation, eliminating concerns about misoperation caused by wireless transmission delays or uncertainties. Following this, the system receives and displays the execution results from the controlled device, bringing the user a clear picture of the remote device's actual response. This achieves a complete control loop from command issuance and device execution to result feedback. This design allows users to confirm the success or failure of command execution and the specific execution effect simply by using the remote control, without having to turn to look at the main display screen of the controlled device or rely on other prompts. This greatly enhances the transparency, reliability, and completeness of human-machine interaction.

[0014] In some embodiments, optionally, after exiting the low-power mode and entering the activation mode in response to detecting a contact, and simultaneously automatically establishing a communication connection with the controlled device, the method further includes: receiving status information of the controlled device from the controlled device; and displaying the status information on the display screen of the remote controller.

[0015] In these embodiments, after establishing a communication connection with the controlled device, the remote control automatically obtains and displays status information from the controlled device. This step allows the user to directly and intuitively read the device status, such as the current volume level or environmental parameter information, on the remote control display screen without operating the controlled device itself or waking up its main screen. This provides the user with a direct and convenient status query channel, improving the efficiency and convenience of human-computer interaction.

[0016] In some embodiments, optionally, receiving the status information of the controlled device from the controlled device includes: receiving a first broadcast data packet from the controlled device, the first broadcast data packet containing at least the basic status information of the controlled device.

[0017] In these embodiments, after the remote controller establishes a communication connection with the controlled device, it initiates a status information synchronization process. Specifically, the step of receiving status information from the controlled device can be achieved by receiving a first broadcast data packet actively sent by the controlled device. The first broadcast data packet contains at least the basic status information of the controlled device, such as device information, beacons, remote control key values, sensor values, and other key states. After entering the active mode and establishing a communication connection, the remote controller continuously listens for or directly receives such broadcast data packets. This broadcast-based communication method allows the controlled device to periodically or actively send data when its state changes, without requiring the remote controller to initiate an additional request each time. After capturing the first broadcast data packet, the remote controller can quickly parse and obtain the basic status information within it. The effect of this mechanism is that it achieves low-power and fast synchronization of status information. The remote controller does not need to perform multiple handshakes and request-response communications with the controlled device to obtain the basic status, reducing communication overhead and latency. This allows the remote controller to be ready in a very short time after the user picks it up, and can also present the basic status of the controlled device to the user, further enhancing the seamless experience of "pick up and use, information synchronization". Users can instantly understand the current status of the controlled device before pressing any function key.

[0018] In some embodiments, optionally, after receiving a first broadcast data packet from a controlled device, the method further includes: determining whether the first broadcast data packet comes from an authorized controlled device; and after identifying that the first broadcast data packet comes from an authorized controlled device, initiating a direct connection request to the controlled device to attempt to establish a one-to-one bidirectional data communication channel.

[0019] In these embodiments, after receiving the first broadcast data packet from the controlled device, the remote controller does not immediately process the status information within it. Instead, it first executes a device authorization verification process. The remote controller parses the first broadcast data packet, extracting device identification information, such as the device's unique MAC address or encrypted device code. This information is then compared with a pre-stored or paired list of authorized devices within the remote controller to determine whether the first broadcast data packet originates from an authorized and trustworthy controlled device. Only after identifying and confirming that the first broadcast data packet originates from an authorized controlled device will the remote controller proactively initiate a direct connection request to this specific controlled device. The purpose of this direct connection request is to attempt to establish a stable, one-to-one, bidirectional data communication channel with the target controlled device, such as a classic Bluetooth connection or a directional Bluetooth Low Energy connection. Compared to broadcast communication, this dedicated channel provides a more reliable, private, and higher bandwidth data link. The effect of this mechanism is that it strikes a balance between convenience and security. By verifying the authorized identity of the broadcast source first, the remote controller can effectively filter broadcast interference from other unauthorized devices in the environment, avoiding the risk of misconnection or information leakage, and ensuring the accuracy and security of control. After successful verification, a dedicated one-to-one connection is established, enabling bidirectional, low-latency, and interference-free exchange of commands and data between the remote control and the controlled device. This not only improves the reliability of control command transmission but also lays the communication foundation for subsequent transmission of more complex commands or large amounts of status information (such as user interface data), enhancing the overall functionality and interaction depth of the system.

[0020] In some embodiments, optionally, when a two-way data communication channel is successfully established, the function commands generated by the remote controller and the status information from the controlled device are transmitted in real time through the two-way data communication channel; when a two-way data communication channel is not successfully established, a second broadcast data packet containing command data is periodically sent, the function commands are transmitted through the periodically sent second broadcast data packet containing command data, and / or the status information is received through a plurality of first broadcast data packets periodically sent by the controlled device.

[0021] In these embodiments, after the remote controller attempts to establish a one-to-one bidirectional data communication channel, the system automatically selects two different communication strategies based on the connection result to ensure control reliability. When a bidirectional data communication channel is successfully established, all function commands generated by the remote controller and status information sent by the controlled device are transmitted in real-time and efficiently through this dedicated and stable bidirectional data communication channel. This mode supports instantaneous and continuous bidirectional data exchange. When a bidirectional data communication channel cannot be successfully established, such as in a complex wireless environment or when device resources are temporarily limited, the system switches to a broadcast-based fault-tolerant communication mode. In this mode, the remote controller periodically sends a second broadcast data packet containing specific command data; function commands are transmitted through this periodic broadcast. Simultaneously, status information is obtained by continuously listening to and receiving multiple first broadcast data packets periodically sent by the controlled device. The direct effect of this design is a significant improvement in the system's robustness and availability in complex environments. Successfully establishing a dedicated channel ensures that, under ideal conditions, command transmission has the advantages of low latency, high reliability, and strong interactivity, suitable for operations requiring rapid response. When a dedicated connection cannot be established, the system automatically degrades to broadcast communication mode. While this mode may be slightly less real-time, it does not rely on a complex connection handshake process, preventing complete control failure due to connection failure. The remote controller can still send commands via unidirectional broadcast and obtain basic status information by listening to broadcasts, maintaining basic control functions and achieving high fault tolerance. This dual-mode communication mechanism allows the remote controller to dynamically select the optimal communication strategy based on real-time network conditions, thus providing users with continuous and usable control services in various practical application scenarios.

[0022] In some embodiments, optionally, after receiving the first broadcast data packet from the controlled device, the method further includes: performing deduplication and reassembly processing on the received duplicate first broadcast data packets to restore the complete state information of the controlled device.

[0023] In these embodiments, after the remote controller receives the first broadcast data packet from the controlled device, it further executes a data packet processing procedure. Specifically, due to the wireless environment or the device's own broadcast strategy, the remote controller may receive multiple identical or partially overlapping first broadcast data packets within a short period of time. The processing unit inside the remote controller parses the received series of first broadcast data packets, identifying the sequence number, timestamp, or data segment identifier contained in each data packet. Based on these identifiers, the processing unit performs deduplication processing on the received duplicate first broadcast data packets, i.e., filtering out redundant data packets with identical content. Simultaneously, if the complete status information is divided into multiple parts and sent through multiple consecutive or spaced first broadcast data packets, the processing unit also sorts and reassembles these data packets according to the data segment identifiers to piece together and reconstruct the complete status information of the controlled device. For example, a detailed settings list of the controlled device may be sent in several broadcast packets, and the remote controller needs to correctly assemble them to obtain a readable complete list. Conversely, without such processing, the remote controller may display duplicate, outdated, or incomplete status information. The effect of deduplicating duplicate packets is to avoid the remote control repeatedly processing and updating the same status information, saving processor computing resources and power consumption, and preventing the display interface from flickering or unnecessary updates due to repeated refreshes. The effect of reassembling segmented broadcast packets is to ensure that the remote control can accurately recover the complete and ordered status information sent by the controlled device from multiple data packets that may arrive out of order, thus ensuring that the information presented on the display screen is accurate and comprehensive. This mechanism improves the reliability and efficiency of the status information synchronization process overall, ensuring that the device status viewed by the user through the remote control is always up-to-date and complete, improving the accuracy of status feedback and user experience.

[0024] In some embodiments, the remote control may optionally include a capacitive sensor disposed in the grip area of ​​the remote control, which detects contact between a human body and the remote control, including: detecting the change in capacitance value generated after the human body contacts the grip area of ​​the remote control through the capacitive sensor; and determining that the human body is in contact with the remote control when the change in capacitance value reaches a preset threshold.

[0025] In these embodiments, the specific implementation of human contact detection by the remote control involves integrating a capacitive sensor within the grip area of ​​the remote control's casing. The step of detecting human contact with the remote control includes continuously or intermittently detecting the capacitance value within its sensing area. When a human body (e.g., a user's palm or fingers) touches or grips the grip area of ​​the remote control, the capacitance value detected by the sensor changes due to the influence of the human body's electrical characteristics. The detection circuit inside the remote control continuously compares the current capacitance value with a reference capacitance value. When the detected capacitance change reaches or exceeds a preset threshold, the remote control's control logic determines that a valid human contact event has occurred, thereby triggering the subsequent mode switching process. Compared to using physical buttons or simple pressure sensors, capacitive detection can sense more subtle pre-contact movements. The advantage of this detection mechanism is that it achieves a balance between high sensitivity and low power consumption. The capacitive sensor itself has extremely low power consumption, making it ideal for continuous operation in low-power mode, providing the remote control with all-weather contact sensing capabilities. The preset threshold effectively filters out minute fluctuations in capacitance caused by changes in ambient humidity or slight object contact, thus preventing false triggers and ensuring that only explicit human contact will wake the remote control, improving detection accuracy and reliability. This design eliminates the need for users to search for or press a specific wake-up button; the remote control is recognized the moment the user naturally holds it, providing a precise triggering basis for the subsequent "touch-ready" experience.

[0026] In some embodiments, optionally, after the function instruction corresponding to the function key is sent to the controlled device via a communication connection in response to the triggering of the function key on the remote control, the method further includes: in response to detecting that the human body and the remote control have not disconnected from each other, and detecting that the remote control has been inactive for a preset time, exiting the activation mode and entering the low power mode.

[0027] In these embodiments, the operating logic of the remote control in active mode has been further optimized, adding a power-saving judgment based on no-operation timeout. Specifically, in active mode, after triggering a function button and sending a function command, the remote control will simultaneously start or reset a no-operation timer. The remote control continuously monitors two conditions: first, it continuously confirms that the human body and the remote control are not disconnected through a capacitive sensor; second, it monitors whether a new function button is triggered or any user operation is performed. When both conditions of "human body contact maintained" and "no operation on the remote control for a preset time" are met simultaneously, the remote control's control logic will determine that the user may have no intention to operate temporarily, and will automatically respond by exiting active mode and re-entering low-power mode. For example, the preset time may be set to 30 seconds. After the user picks up the remote control to change channels, if they continue to hold the remote control but do not perform any operation for more than 30 seconds, the remote control will also automatically go into sleep mode. The direct effect of this supplementary mechanism is that it further refines and optimizes the power management strategy, improving energy-saving efficiency. The original method, which relied solely on "disconnection" as the condition for returning to low power, would keep the remote control in a high-power active state if the user continued to hold the remote control but paused operation. The newly added timeout return mechanism allows the remote control to more intelligently determine the user's actual usage intentions. When it senses that the user may not need to operate it temporarily, it automatically enters a low-power state even while still being held, thus saving ineffective energy consumption during this inactive holding period and extending the overall battery life. This represents a significant improvement to the "power saving after use" logic while maintaining the convenience of "pick up and use," making power consumption control more aligned with actual usage habits.

[0028] A second aspect of the present invention provides a remote control control system, comprising: a remote control control method as described in any of the technical solutions of the first aspect, the remote control control system comprising: a capacitive sensor for detecting whether a human body is in contact with the remote control; a transceiver for establishing a communication connection with a controlled device in an active mode; and a main control processor connected to the capacitive sensor and the transceiver respectively, for causing the remote control to enter a low-power mode or an active mode based on the detection result of the capacitive sensor, and for controlling the transceiver to establish a communication connection with the controlled device in the active mode.

[0029] The remote control system provided by the present invention is used to implement the remote control control method as described in any of the technical solutions of the first aspect. The remote control system includes a capacitive sensor, a transceiver, and a main control processor. The capacitive sensor, typically integrated under the outer shell of the remote control's grip area, is used to continuously or intermittently detect whether a human body is in contact with the remote control; it operates by sensing changes in capacitance caused by human proximity or touch. The transceiver, such as a Bluetooth or infrared transceiver module, is used to establish and maintain a communication connection with the target controlled device according to instructions after the remote control enters active mode, and is responsible for transmitting and receiving wireless signals. The main control processor, as the control core, is electrically connected to both the capacitive sensor and the transceiver. The main control processor runs a basic program in low-power mode, receiving and processing detection signals from the capacitive sensor. When the detection result of the capacitive sensor indicates that a human body is in contact with the remote control, the main control processor accordingly controls the remote control to exit low-power mode and switch to full-function active mode. In active mode, the main control processor further controls the transceiver to initiate and establish a communication connection with the controlled device. In addition, the main control processor is also responsible for processing the input of function keys, generating corresponding function commands, and sending them through the transceiver, as well as processing feedback information received from the controlled device through the transceiver. This system, through the collaboration of dedicated hardware components, operates on the principle that a capacitive sensor provides a contact detection signal as the trigger source for system state switching. The main control processor, as the decision-making and coordination center, controls the power management mode and the start / stop of functional modules based on this trigger source, and directs the transceiver to establish a communication link. This hardware architecture realizes an automated pipeline from detection to readiness. Distributing detection, connection establishment, and mode management functions to dedicated units such as the capacitive sensor, transceiver, and main control processor directly improves the system's response speed and energy efficiency. The capacitive sensor is specifically responsible for high-sensitivity, low-power contact sensing, allowing the remote control to maintain its "sensing" capability with extremely low power consumption when in sleep mode. The main control processor, as the central controller, can efficiently and reliably execute complex mode switching and task scheduling logic. The transceiver is precisely started and stopped when needed, avoiding idle power consumption in a disconnected state. This clearly defined hardware system ensures, at the physical level, that the "contact detection, detection wake-up, wake-up connection" process can be executed with extremely high reliability and extremely short latency, thereby supporting zero-latency response and seamless control experience at the hardware level, while minimizing the overall power consumption of the system.

[0030] A third aspect of the present invention provides a remote control device, including a contact detection module and a mode switching and connection module. The contact detection module is used to detect contact between a human body and the remote control when the remote control is in a low-power mode. The mode switching and connection module is used to exit the low-power mode and enter the active mode in response to the detection of contact, and simultaneously automatically establish a communication connection with the controlled device.

[0031] The remote control device provided by this invention includes a contact detection module and a mode switching and connection module. The contact detection module is the basic sensing unit that operates continuously in the device. When the remote control is in low-power mode, this module operates continuously with extremely low power consumption. It detects the contact between the human body and the remote control casing through detection elements such as a capacitive sensor integrated in the remote control's grip area. For example, it determines whether a valid grip has occurred by monitoring whether the capacitance value change exceeds a preset threshold. The mode switching and connection module is the control and coordination core of the device. Responding to a valid contact signal from the contact detection module, it immediately generates a control command, causing the remote control's power management unit and main control processor to exit low-power mode and enter a full-function active mode. Simultaneously, this module synchronously drives the wireless communication unit to automatically initiate and complete the communication connection establishment process with the controlled device. This device improves system reliability and maintainability by decomposing functions into dedicated modules. The clear responsibilities of each module allow for independent optimization and efficient execution of tasks such as detection and connection. The specialized design of the contact detection module ensures detection sensitivity and low power consumption, providing a foundation for zero standby power consumption of the entire system. The mode switching and connection module binds the wake-up and connection actions into an automated, continuous process, eliminating user waiting at the system level and achieving a seamless, ready-to-go experience.

[0032] A third aspect of the present invention provides a remote control device, including a memory and a processor. The memory stores a program or instructions, and when the program or instructions are executed by the processor, the steps of the remote control method in any of the technical solutions of the first aspect are implemented.

Detailed Implementation

[0057] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0059] The following reference Figures 1 to 16 This invention describes a remote control method, control system, and control device proposed according to some embodiments of the present invention.

[0060] like Figure 1 As shown, according to an embodiment of the first aspect of the present invention, a remote control method is provided, comprising:

[0061] S102, when the remote control is in low power mode, detects contact between a human body and the remote control;

[0062] S104, in response to the detection of contact, exits the low-power mode and enters the activation mode, and at the same time automatically establishes a communication connection with the controlled device.

[0063] According to the remote control method provided by this invention, when the remote control is in low-power mode, it operates with extremely low power consumption and continuously detects whether a human body is in contact with it. Once contact is detected, the remote control immediately responds, exiting the low-power mode and entering the full-function active mode. Simultaneously, it automatically establishes a communication connection with the controlled device. It is understood that the remote control normally only operates the human contact detection function in low-power mode to maintain extremely low power consumption. When a human contact event is detected, the remote control uses this as a wake-up signal and immediately executes three consecutive actions: exiting the low-power mode, switching to the full-function active mode, and simultaneously initiating the communication connection establishment process with the controlled device. This design allows the wake-up ready process of the remote control to overlap in time with the user's natural action of picking up the remote control. The user does not need to perform a special wake-up operation; the remote control has already completed function activation and communication preparation when the user picks it up, thus achieving a zero-delay control response that is ready upon contact. Since the communication connection is established automatically and synchronously when entering activation mode, the communication link between the remote control and the device is ready the moment the user picks up the remote control. The user can directly trigger the function keys to operate, which eliminates the steps of waiting for connection or manually establishing connection after waking up in the traditional way, and brings a seamless control experience that can be used immediately after picking up the device.

[0064] In some embodiments, optionally, such as Figure 2 As shown, after responding to the detection of contact, exiting the low-power mode, entering the activation mode, and simultaneously automatically establishing a communication connection with the controlled device, the method further includes:

[0065] S106, in response to the triggering of the function button on the remote control, sends the function command corresponding to the function button to the controlled device through the communication connection.

[0066] S108, in response to detecting that a human body has lost contact with the remote control, exits the activation mode and enters the low power mode.

[0067] In these embodiments, in active mode, when a user triggers any function button on the remote control, the remote control generates a function command corresponding to that button and sends the command to the controlled device via the established communication connection to execute the corresponding operation. Finally, when the remote control detects that the human body has disconnected from it, it responds again, automatically exiting active mode and re-entering low-power mode. When the remote control detects that the human body has disconnected, the system determines that use is complete, automatically exits active mode, and returns to low-power mode. This mode management, which uses the user's physical contact as a switch, ensures that the remote control immediately shuts off power to most functional circuits after being removed from the user's hand, minimizing unnecessary standby power consumption and effectively reducing the overall energy consumption of the remote control, significantly extending the battery life after a single charge or battery replacement.

[0068] In some embodiments, optionally, in the activation mode, after the function instruction corresponding to the function key is sent to the controlled device via a communication connection in response to the triggering of the function key on the remote control, the method further includes: displaying the function instruction on the display screen of the remote control; receiving the execution result of the function instruction from the controlled device; and displaying the execution result on the display screen.

[0069] In these embodiments, when the remote control is in active mode and sends a function command to the controlled device in response to a function button press, the remote control further executes a closed-loop feedback process. Specifically, simultaneously with or immediately after sending the function command via the communication connection, the remote control immediately displays the relevant indication of the function command on its built-in display screen, such as indicating in text, icon, or code form that the currently sent command is "volume up" or "channel switch". Subsequently, the remote control receives the execution result of the function command from the controlled device. The execution result can be a confirmation signal of successful operation or updated device status data after execution. The remote control finally updates and displays this execution result on the display screen. For example, after the user presses the volume up button, the display screen first displays a "volume +" prompt, and then receives and displays "volume adjusted to 25". The effect of this process is that it provides instant, visual local confirmation and remote result feedback for each user control operation. Displaying the sent function command on the remote control's display screen allows the user to immediately confirm that the remote control has correctly responded to their button operation, eliminating concerns about misoperation caused by wireless transmission delays or uncertainties. Following this, the system receives and displays the execution results from the controlled device, bringing the user a clear picture of the remote device's actual response. This achieves a complete control loop from command issuance and device execution to result feedback. This design allows users to confirm the success or failure of command execution and the specific execution effect simply by using the remote control, without having to turn to look at the main display screen of the controlled device or rely on other prompts. This greatly enhances the transparency, reliability, and completeness of human-machine interaction.

[0070] In some embodiments, optionally, after exiting the low-power mode and entering the activation mode in response to detecting a contact, and simultaneously automatically establishing a communication connection with the controlled device, the method further includes: receiving status information of the controlled device from the controlled device; and displaying the status information on the display screen of the remote controller.

[0071] In these embodiments, after establishing a communication connection with the controlled device, the remote control automatically obtains and displays status information from the controlled device. This step allows the user to directly and intuitively read the device status, such as the current volume level or environmental parameter information, on the remote control display screen without operating the controlled device itself or waking up its main screen. This provides the user with a direct and convenient status query channel, improving the efficiency and convenience of human-computer interaction.

[0072] In some embodiments, optionally, receiving the status information of the controlled device from the controlled device includes: receiving a first broadcast data packet from the controlled device, the first broadcast data packet containing at least the basic status information of the controlled device.

[0073] In these embodiments, after the remote controller establishes a communication connection with the controlled device, it initiates a status information synchronization process. Specifically, the step of receiving status information from the controlled device can be achieved by receiving a first broadcast data packet actively sent by the controlled device. The first broadcast data packet contains at least the basic status information of the controlled device, such as device information, beacons, remote control key values, sensor values, and other key states. After entering the active mode and establishing a communication connection, the remote controller continuously listens for or directly receives such broadcast data packets. This broadcast-based communication method allows the controlled device to periodically or actively send data when its state changes, without requiring the remote controller to initiate an additional request each time. After capturing the first broadcast data packet, the remote controller can quickly parse and obtain the basic status information within it. The effect of this mechanism is that it achieves low-power and fast synchronization of status information. The remote controller does not need to perform multiple handshakes and request-response communications with the controlled device to obtain the basic status, reducing communication overhead and latency. This allows the remote controller to be ready in a very short time after the user picks it up, and can also present the basic status of the controlled device to the user, further enhancing the seamless experience of "pick up and use, information synchronization". Users can instantly understand the current status of the controlled device before pressing any function key.

[0074] In one specific embodiment, such as Figure 7 As shown, the broadcasting device does not need to be continuously active; it sends broadcasts at time intervals and can transmit information without connecting to other devices. It supports multiple devices receiving broadcast data simultaneously, achieving one-to-many unidirectional data transmission. After sending the data packet, the broadcaster immediately enters a low-power standby mode, waiting for the next broadcast time before waking up again to send broadcast data.

[0075] In some embodiments, optionally, after receiving a first broadcast data packet from a controlled device, the method further includes: determining whether the first broadcast data packet comes from an authorized controlled device; and after identifying that the first broadcast data packet comes from an authorized controlled device, initiating a direct connection request to the controlled device to attempt to establish a one-to-one bidirectional data communication channel.

[0076] In these embodiments, after receiving the first broadcast data packet from the controlled device, the remote controller does not immediately process the status information within it. Instead, it first executes a device authorization verification process. The remote controller parses the first broadcast data packet, extracting device identification information, such as the device's unique MAC address or encrypted device code. This information is then compared with a pre-stored or paired list of authorized devices within the remote controller to determine whether the first broadcast data packet originates from an authorized and trustworthy controlled device. Only after identifying and confirming that the first broadcast data packet originates from an authorized controlled device will the remote controller proactively initiate a direct connection request to this specific controlled device. The purpose of this direct connection request is to attempt to establish a stable, one-to-one, bidirectional data communication channel with the target controlled device, such as a classic Bluetooth connection or a directional Bluetooth Low Energy connection. Compared to broadcast communication, this dedicated channel provides a more reliable, private, and higher bandwidth data link. The effect of this mechanism is that it strikes a balance between convenience and security. By verifying the authorized identity of the broadcast source first, the remote controller can effectively filter broadcast interference from other unauthorized devices in the environment, avoiding the risk of misconnection or information leakage, and ensuring the accuracy and security of control. After successful verification, a dedicated one-to-one connection is established, enabling bidirectional, low-latency, and interference-free exchange of commands and data between the remote control and the controlled device. This not only improves the reliability of control command transmission but also lays the communication foundation for subsequent transmission of more complex commands or large amounts of status information (such as user interface data), enhancing the overall functionality and interaction depth of the system.

[0077] In direct connection mode, two devices achieve one-to-one bidirectional data communication, with each device continuously and actively monitoring the other's data. Compared to broadcast mode, this mode can transmit more data, but consumes more power. Figure 8 As shown, the device consists of a master device (remote controller) and a slave device (controlled device). The slave device must be in broadcast mode beforehand. After the master device scans the broadcast information packet of the slave device, if it confirms that the other party is a paired (authorized) device, it will actively initiate a direct connection with the slave device. After the master and slave devices establish a stable connection, they can send and receive data to each other. This mode is suitable for scenarios that require bidirectional communication, large data volume, and low latency.

[0078] In some embodiments, optionally, when a two-way data communication channel is successfully established, the function commands generated by the remote controller and the status information from the controlled device are transmitted in real time through the two-way data communication channel; when a two-way data communication channel is not successfully established, a second broadcast data packet containing command data is periodically sent, the function commands are transmitted through the periodically sent second broadcast data packet containing command data, and / or the status information is received through a plurality of first broadcast data packets periodically sent by the controlled device.

[0079] In these embodiments, after the remote controller attempts to establish a one-to-one bidirectional data communication channel, the system automatically selects two different communication strategies based on the connection result to ensure control reliability. When a bidirectional data communication channel is successfully established, all function commands generated by the remote controller and status information sent by the controlled device are transmitted in real-time and efficiently through this dedicated and stable bidirectional data communication channel. This mode supports instantaneous and continuous bidirectional data exchange. When a bidirectional data communication channel cannot be successfully established, such as in a complex wireless environment or when device resources are temporarily limited, the system switches to a broadcast-based fault-tolerant communication mode. In this mode, the remote controller periodically sends a second broadcast data packet containing specific command data; function commands are transmitted through this periodic broadcast. Simultaneously, status information is obtained by continuously listening to and receiving multiple first broadcast data packets periodically sent by the controlled device. The direct effect of this design is a significant improvement in the system's robustness and availability in complex environments. Successfully establishing a dedicated channel ensures that, under ideal conditions, command transmission has the advantages of low latency, high reliability, and strong interactivity, suitable for operations requiring rapid response. When a dedicated connection cannot be established, the system automatically degrades to broadcast communication mode. While this mode may be slightly less real-time, it does not rely on a complex connection handshake process, preventing complete control failure due to connection failure. The remote controller can still send commands via unidirectional broadcast and obtain basic status information by listening to broadcasts, maintaining basic control functions and achieving high fault tolerance. This dual-mode communication mechanism allows the remote controller to dynamically select the optimal communication strategy based on real-time network conditions, thus providing users with continuous and usable control services in various practical application scenarios.

[0080] Among them, such as Figure 9 As shown, when the remote control senses that it has been picked up, it automatically wakes up its other peripherals and simultaneously scans for broadcast packets in the vicinity. After scanning for broadcast packets from authorized devices, the remote control parses the information within the packets and displays it on the screen, while simultaneously initiating a direct connection to the device. Upon receiving the direct connection request, the controlled device wakes up its other peripherals, transitioning from a low-power standby state to a normal operating state. For example, sensors refresh their collected values, and a handshake attempt is made to establish a connection. If the direct connection is successful, the device sends more complete and up-to-date data to the remote control, which analyzes and processes it before displaying it on the screen. When the user presses a button, the remote control sends the corresponding key value to the controlled device via direct connection. Upon receiving the key value, the device executes the corresponding command. If the information that the device needs to interact with changes, it will proactively send this information to the remote control to ensure that the remote control can display the latest information in real time.

[0081] In some embodiments, optionally, after receiving the first broadcast data packet from the controlled device, the method further includes: performing deduplication and reassembly processing on the received duplicate first broadcast data packets to restore the complete state information of the controlled device.

[0082] In these embodiments, after the remote controller receives the first broadcast data packet from the controlled device, it further executes a data packet processing procedure. Specifically, due to the wireless environment or the device's own broadcast strategy, the remote controller may receive multiple identical or partially overlapping first broadcast data packets within a short period of time. The processing unit inside the remote controller parses the received series of first broadcast data packets, identifying the sequence number, timestamp, or data segment identifier contained in each data packet. Based on these identifiers, the processing unit performs deduplication processing on the received duplicate first broadcast data packets, i.e., filtering out redundant data packets with identical content. Simultaneously, if the complete status information is divided into multiple parts and sent through multiple consecutive or spaced first broadcast data packets, the processing unit also sorts and reassembles these data packets according to the data segment identifiers to piece together and reconstruct the complete status information of the controlled device. For example, a detailed settings list of the controlled device may be sent in several broadcast packets, and the remote controller needs to correctly assemble them to obtain a readable complete list. Conversely, without such processing, the remote controller may display duplicate, outdated, or incomplete status information. The effect of deduplicating duplicate packets is to avoid the remote control repeatedly processing and updating the same status information, saving processor computing resources and power consumption, and preventing the display interface from flickering or unnecessary updates due to repeated refreshes. The effect of reassembling segmented broadcast packets is to ensure that the remote control can accurately recover the complete and ordered status information sent by the controlled device from multiple data packets that may arrive out of order, thus ensuring that the information presented on the display screen is accurate and comprehensive. This mechanism improves the reliability and efficiency of the status information synchronization process overall, ensuring that the device status viewed by the user through the remote control is always up-to-date and complete, improving the accuracy of status feedback and user experience.

[0083] In some embodiments, the remote control may optionally include a capacitive sensor disposed in the grip area of ​​the remote control, which detects contact between a human body and the remote control, including: detecting the change in capacitance value generated after the human body contacts the grip area of ​​the remote control through the capacitive sensor; and determining that the human body is in contact with the remote control when the change in capacitance value reaches a preset threshold.

[0084] In these embodiments, the specific implementation of human contact detection by the remote control involves integrating a capacitive sensor within the grip area of ​​the remote control's casing. The step of detecting human contact with the remote control includes continuously or intermittently detecting the capacitance value within its sensing area. When a human body (e.g., a user's palm or fingers) touches or grips the grip area of ​​the remote control, the capacitance value detected by the sensor changes due to the influence of the human body's electrical characteristics. The detection circuit inside the remote control continuously compares the current capacitance value with a reference capacitance value. When the detected capacitance change reaches or exceeds a preset threshold, the remote control's control logic determines that a valid human contact event has occurred, thereby triggering the subsequent mode switching process. Compared to using physical buttons or simple pressure sensors, capacitive detection can sense more subtle pre-contact movements. The advantage of this detection mechanism is that it achieves a balance between high sensitivity and low power consumption. The capacitive sensor itself has extremely low power consumption, making it ideal for continuous operation in low-power mode, providing the remote control with all-weather contact sensing capabilities. The preset threshold effectively filters out minute fluctuations in capacitance caused by changes in ambient humidity or slight object contact, thus preventing false triggers and ensuring that only explicit human contact will wake the remote control, improving detection accuracy and reliability. This design eliminates the need for users to search for or press a specific wake-up button; the remote control is recognized the moment the user naturally holds it, providing a precise triggering basis for the subsequent "touch-ready" experience.

[0085] In some embodiments, optionally, after the function instruction corresponding to the function key is sent to the controlled device via a communication connection in response to the triggering of the function key on the remote control, the method further includes: in response to detecting that the human body and the remote control have not disconnected from each other, and detecting that the remote control has been inactive for a preset time, exiting the activation mode and entering the low power mode.

[0086] In these embodiments, the operating logic of the remote control in active mode has been further optimized, adding a power-saving judgment based on no-operation timeout. Specifically, in active mode, after triggering a function button and sending a function command, the remote control will simultaneously start or reset a no-operation timer. The remote control continuously monitors two conditions: first, it continuously confirms that the human body and the remote control are not disconnected through a capacitive sensor; second, it monitors whether a new function button is triggered or any user operation is performed. When both conditions of "human body contact maintained" and "no operation on the remote control for a preset time" are met simultaneously, the remote control's control logic will determine that the user may have no intention to operate temporarily, and will automatically respond by exiting active mode and re-entering low-power mode. For example, the preset time may be set to 30 seconds. After the user picks up the remote control to change channels, if they continue to hold the remote control but do not perform any operation for more than 30 seconds, the remote control will also automatically go into sleep mode. The direct effect of this supplementary mechanism is that it further refines and optimizes the power management strategy, improving energy-saving efficiency. The original method, which relied solely on "disconnection" as the condition for returning to low power, would keep the remote control in a high-power active state if the user continued to hold the remote control but paused operation. The newly added timeout return mechanism allows the remote control to more intelligently determine the user's actual usage intentions. When it senses that the user may not need to operate it temporarily, it automatically enters a low-power state even while still being held, thus saving ineffective energy consumption during this inactive holding period and extending the overall battery life. This represents a significant improvement to the "power saving after use" logic while maintaining the convenience of "pick up and use," making power consumption control more aligned with actual usage habits.

[0087] like Figure 3 As shown, according to an embodiment of the first aspect of the present invention, a remote control method is provided, comprising:

[0088] S202, detect whether the remote control has been picked up.

[0089] S204 wakes up the entire unit when the remote control is picked up.

[0090] S206, actively connect to the controlled device.

[0091] S208, synchronize controlled device information.

[0092] S210 displays the status information of the controlled device on the screen.

[0093] According to the remote control method provided by this invention, once the remote control is detected to be picked up, it immediately responds, wakes up the entire device, exits the low-power mode, and enters the full-function activation mode. Simultaneously, it automatically establishes a communication connection with the controlled device. After establishing the communication connection, the remote control automatically obtains and displays status information from the controlled device. This step allows the user to directly and intuitively read the device status, such as the current volume level or environmental parameter information, on the remote control's display screen without operating the controlled device itself or waking up its main screen. This provides users with a direct and convenient status query channel, improving the efficiency and convenience of human-computer interaction.

[0094] Meanwhile, since the communication connection is established automatically and synchronously upon wake-up, the communication link between the remote control and the device is ready the moment the user picks up the remote control. The user can directly trigger the function keys to operate, which eliminates the steps of waiting for connection or manually establishing connection after wake-up in the traditional way, bringing a seamless control experience that can be used immediately upon picking up the device.

[0095] like Figure 4 As shown, according to an embodiment of the first aspect of the present invention, a remote control method is provided, comprising:

[0096] S302, the remote control was picked up.

[0097] S304, wake up the machine.

[0098] S306, No operation timeout, proceed to S308.

[0099] S308, delayed display.

[0100] S310 enters hibernation mode.

[0101] S312, the remote control is put down, and S308 and S310 are executed in sequence.

[0102] S314, button operation, executes S316.

[0103] S316, wireless transceiver.

[0104] S318, Information Echo.

[0105] According to the remote control method provided by this invention, when the remote control is in wake-up mode and sends a function command to the controlled device in response to the triggering of a function key, the remote control further executes a closed-loop feedback process. Specifically, while or immediately after sending a function command via the communication connection, the remote control immediately displays the relevant indication of the function command on its built-in display screen, such as indicating in text, icon, or code form that the currently sent command is "volume increase" or "channel switch". Subsequently, the remote control receives the execution result of the function command from the controlled device. The execution result can be a confirmation signal of successful operation or updated device status data after execution. The remote control finally updates and displays this execution result on the display screen. For example, after the user presses the volume up button, the display screen first displays a "volume +" prompt, and then receives and displays "volume adjusted to 25". The effect of this process is that it provides instant, visual local confirmation and remote result feedback for each control operation by the user. Displaying the sent function command on the remote control's display screen allows the user to immediately confirm that the remote control has correctly responded to its button operation, eliminating concerns about misoperation caused by wireless transmission delays or uncertainties. Following this, the system receives and displays the execution results from the controlled device, bringing the user a clear picture of the remote device's actual response. This achieves a complete control loop from command issuance and device execution to result feedback. This design allows users to confirm the success or failure of command execution and the specific execution effect simply by using the remote control, without having to turn to look at the main display screen of the controlled device or rely on other prompts. This greatly enhances the transparency, reliability, and completeness of human-machine interaction.

[0106] like Figure 5 The diagram shown is a flowchart illustrating the interaction between the remote controller and the controlled device in one embodiment of this application, including:

[0107] S402, Controlled device: Low power standby.

[0108] S404 wakes up peripherals such as sensors and displays when it receives a direct connection request.

[0109] S406, sensor refresh data.

[0110] S408, attempting a direct handshake connection with the remote control.

[0111] S410: If the connection is successful, send complete data to the remote control.

[0112] S412, the remote control analyzes and displays the data.

[0113] S414, Does the user press a key? If the user presses a key, execute S416; if the user does not press a key, execute S426.

[0114] S416, send key values ​​to the controlled device.

[0115] S418, the controlled device executes the instruction.

[0116] S420: Has the state changed? If the state has changed, execute S424; if the state has not changed, execute S422.

[0117] S422, awaiting the next instruction.

[0118] S424 actively pushes new data to the remote control.

[0119] S426, keep listening.

[0120] like Figure 6 The diagram shown is a flowchart illustrating the interaction between the remote controller and the controlled device in one embodiment of this application, including:

[0121] S502, remote control button operation.

[0122] S504: Is the direct connection stable? If the direct connection is unstable, proceed to S506; if the direct connection is stable, proceed to S520.

[0123] S506, Remote Control: Segmented key value broadcast packets.

[0124] S508, Device: Monitors broadcast channel.

[0125] Upon receiving a key-value broadcast packet, the S510 device performs deduplication and executes the corresponding operation.

[0126] S512, Device: Sends full data broadcast packets in segments.

[0127] S514, Remote Control: Monitors broadcast channels.

[0128] S516, upon receiving a data broadcast packet, the remote control deduplicates and reassembles the data.

[0129] S518 analyzes and refreshes the display.

[0130] S520, normal direct communication.

[0131] This invention provides a wireless remote control and its control method. Addressing the issues of lack of status feedback (users cannot know the execution results of commands such as the actual air conditioner temperature) caused by the common use of infrared or RF (Radio Frequency) unidirectional communication in existing remote controls, and the inefficiency, latency, high power consumption, and high cost of traditional button or motion sensor wake-up methods, a systematic solution is proposed. For example, traditional remote controls have an inherent response time when waking from sleep mode to full-function operation. If a user immediately presses a button after picking up the remote, before the system has completed startup, wireless connection, and data synchronization, the button commands cannot be responded to in time, or the screen information display is delayed, leading to an interrupted user experience and user confusion. The remote control in this application is required to enter a low-power mode when there is no operation, and to respond immediately when the user uses it, completing information synchronization and display with the device, thereby enhancing operational visualization and responsiveness while reducing overall power consumption.

[0132] To achieve the above objectives, such as Figure 11 As shown, the hardware architecture of the remote control (remote control body 114) includes a main control processor 106, a two-way transceiver 104 supporting protocols such as Bluetooth / Wi-Fi (Wireless Fidelity), a display screen 108, such as an LCD (Liquid Crystal Display) or OLED (Organic Light-Emitting Diode), a button array 110, a multi-area capacitive sensor 102, and a power supply battery 112. The transceiver is used to establish a two-way channel with the controlled device (such as a television or air conditioner) to enable the issuance of control commands and the transmission of device status. The display screen is used to display the current operating parameters of the device in real time (such as channel, volume, and playback progress). The capacitive sensor covers the remote control's grip area, specifically through a specially arranged copper foil (such as...) arranged on the inner side of the casing. Figure 10 (As shown by the dashed line in the middle), a distributed touch sensing network is formed by connecting capacitive sensors on the motherboard via wires. This network detects the gradient changes in global capacitance caused by hand contact, thereby accurately determining the user's gripping action. The main control processor coordinates the various modules and executes low-power scheduling algorithms. The display and buttons are integrated into a single layout and remain off in standby mode to save power.

[0133] This application uses a capacitive sensor to detect human contact in real time, replacing physical buttons for wake-up. In sleep mode (low-power mode), when the user picks up the remote control, the hand surrounding the remote control causes a change in capacitance. The system determines this as a valid grip within milliseconds and triggers a zero-latency full-device wake-up, simultaneously activating the wireless module. At this time, the remote control automatically searches for and attempts to connect to the controlled device. The controlled device is in broadcast mode by default, periodically sending broadcast packets containing basic status information (such as operating status). After the remote control scans a broadcast packet from a bound device (both parties are pre-paired and have their MAC (Media Access Control Address) addresses saved), it immediately parses the packet and displays the information synchronously on the screen, achieving rapid initial feedback. Simultaneously, the remote control initiates a direct connection request to the device. After establishing a stable one-to-one bidirectional connection, the device sends more complete and up-to-date full data to the remote control to update the display. The entire "connection-synchronization-display" process is completed instantaneously within the time interval from when the user picks up the remote control to when they hold it in front of them, achieving "screen wake-up upon picking up," ensuring that the information is updated in real time when the user sees the screen.

[0134] like Figure 15 As shown, in the current scenario, the remote control 114 is placed on a table, positioned diagonally below and in front of the user's line of sight at a considerable distance, making it difficult for the user to clearly discern the displayed content on the remote control 114. Therefore, the display screen 108 does not need to be turned on at this time and can remain off to save power. When the user touches the remote control 114, the capacitive sensor 102 detects the human contact signal. After signal analysis and filtering, the system is activated when a preset threshold is reached.

[0135] like Figure 16 As shown, when the user picks up the remote control body 114 and brings it into their line of sight, the remote control body 114 automatically completes the connection with the controlled device and displays the device status information in real time. This design cleverly integrates device connection, information synchronization, and status display into the user's natural picking action, achieving a seamless user experience.

[0136] In low-power standby mode, the controlled device (such as a television or air conditioner) typically only maintains the operation of its wireless broadcast module and basic monitoring circuitry. Upon receiving a direct connection request from an authorized remote controller, the device's main controller is awakened and subsequently activates other necessary peripherals and functional modules within the device (e.g., waking up the display driver circuit, activating environmental sensors such as temperature / humidity for refresh sampling, and initializing the audio / video processing unit), transitioning the device from low-power standby mode to full normal operation. Subsequently, the device and remote controller establish a connection handshake, and only after a stable direct connection channel is established can the device send a complete status data packet, including the latest sampled values ​​and setting parameters, to the remote controller.

[0137] In activation mode, users operate via buttons, and the remote control sends the key values ​​to the device through a direct connection channel. The device executes the commands and projects the latest status back to the remote control screen in real time, eliminating the need for user look-up confirmation. If a stable direct connection cannot be established or maintained due to environmental interference, the system automatically switches to broadcast mode for degraded communication. After a user presses a button, the remote control periodically sends broadcast packets containing the corresponding key values ​​multiple times. The device deduplicates these packets before execution. The device's full information is also split into multiple broadcast packets and sent multiple times, which are then reassembled and deduplicated by the remote control before display. This ensures controllability and display while handling complex environments.

[0138] The display screen and physical buttons are integrated into a single layout. In standby (sleep) mode, the display screen operates at extremely low power consumption, either off or at ultra-low brightness, displaying no content to conserve energy. Only when the capacitive sensor wakes the system and the wireless module begins receiving data, or when a user touches a physical button, is the corresponding area (or the entire display) dynamically and instantly illuminated. During button operation, the screen not only displays the device's feedback status (such as volume and temperature values) but also provides real-time visual cues relevant to the current operation context, such as highlighting the function icon of the pressed button, animated feedback of successful command transmission, or indicators of currently adjustable parameters. This design ensures that the screen consumes power only when necessary, while providing rich visual operational feedback.

[0139] When the capacitive sensor detects that the remote control has been placed down (capacitance value restored) or has been inactive for an extended period, the system determines that use has ended. After a short delay, it automatically turns off the screen and controls all modules to enter deep sleep mode, forming a closed-loop low-power management system of "power off upon placement". This embodiment achieves zero-delay wake-up through capacitive sensing, combining a hybrid communication mode of broadcast (for rapid discovery, initial synchronization, and redundant communication) and direct connection (for real-time, full-volume bidirectional interaction), and relying on intelligent power consumption scheduling, systematically solving four core problems: response delay, information asynchrony, high ineffective power consumption, and the contradiction between visualization and energy consumption. It achieves a balance between zero-delay operation visualization and high efficiency and low power consumption with a low-cost capacitive solution.

[0140] like Figure 12As shown, a second aspect of the present invention provides a remote control control system 10, comprising: a remote control control method as described in any embodiment of the first aspect, the remote control control system 10 comprising: a capacitive sensor 102 for detecting whether a human body is in contact with the remote control; a transceiver 104 for establishing a communication connection with a controlled device in an active mode; and a main control processor 106 connected to the capacitive sensor 102 and the transceiver 104 respectively, for causing the remote control to enter a low-power mode or an active mode based on the detection result of the capacitive sensor 102, and for controlling the transceiver 104 to establish a communication connection with the controlled device in the active mode.

[0141] The remote control system 10 provided by the present invention is used to implement the remote control control method as described in any embodiment of the first aspect. The remote control system 10 includes a capacitive sensor 102, a transceiver 104, and a main control processor 106. The capacitive sensor 102, typically integrated under the outer shell of the grip area of ​​the remote control, is used to continuously or intermittently detect whether a human body is in contact with the remote control. It operates by sensing changes in capacitance caused by the proximity or touch of a human body. The transceiver 104, such as a Bluetooth or infrared transceiver module, is used to establish and maintain a communication connection with the target controlled device according to instructions after the remote control enters the active mode, and is responsible for transmitting and receiving wireless signals. The main control processor 106, as the control core, is electrically connected to both the capacitive sensor 102 and the transceiver 104. The main control processor 106 runs a basic program in low-power mode, receiving and processing detection signals from the capacitive sensor 102. When the detection result of the capacitive sensor 102 indicates that a human body is in contact with the remote control, the main control processor 106 controls the remote control to exit the low-power mode and switch to the active mode for full-function operation. In active mode, the main control processor 106 further controls the transceiver 104 to initiate and establish a communication connection with the controlled device. In addition, the main control processor 106 is also responsible for processing function key inputs, generating corresponding function commands, and sending them through the transceiver 104, as well as processing feedback information received from the controlled device through the transceiver 104. This system, through the collaboration of dedicated hardware components, operates on the principle that the capacitive sensor 102 provides a contact detection signal as the trigger source for system state switching. The main control processor 106, as the decision-making and coordination center, controls the power management mode and the start / stop of functional modules based on this trigger source, and directs the transceiver 104 to establish a communication link. This hardware architecture realizes an automated pipeline from detection to readiness. Assigning detection, connection establishment, and mode management functions to dedicated units such as the capacitive sensor 102, transceiver 104, and main control processor 106 directly improves the system's response speed and energy efficiency. The capacitive sensor 102 is specifically responsible for high-sensitivity, low-power contact sensing, allowing the remote control to maintain its "sensing" capability with extremely low power consumption when in sleep mode. The main control processor 106, acting as the central controller, can efficiently and reliably execute complex mode switching and task scheduling logic. The transceiver 104 is precisely started and stopped when needed, avoiding wasted power in the non-connected state. This clearly defined hardware system ensures, at the physical level, that the "contact detection, detection wake-up, wake-up connection" process can be executed with extremely high reliability and extremely low latency, thereby supporting zero-latency response and seamless control experience at the hardware level, while minimizing the overall power consumption of the system.

[0142] like Figure 13As shown, a third aspect of the present invention provides a remote control device 20, including a contact detection module 202 and a mode switching and connection module 204. The contact detection module 202 is used to detect contact between a human body and the remote control when the remote control is in a low power mode. The mode switching and connection module 204 is used to exit the low power mode and enter the active mode in response to the detection of contact, and at the same time automatically establish a communication connection with the controlled device.

[0143] The remote control device 20 provided by this invention includes a contact detection module 202 and a mode switching and connection module 204. The contact detection module 202 is the basic sensing unit that is always running in the device. When the remote control is in low-power mode, this module operates continuously with extremely low power consumption. It senses the contact between the human body and the remote control casing through detection elements such as a capacitive sensor integrated in the remote control's gripping area. For example, it determines whether a valid grip has occurred by monitoring whether the change in capacitance value exceeds a preset threshold. The mode switching and connection module 204 is the control and coordination core of the device. In response to the valid contact signal issued by the contact detection module 202, it immediately generates a control command, causing the remote control's power management unit and main control processor to exit the low-power mode and enter the full-function active mode. Simultaneously, this module synchronously drives the wireless communication unit to automatically initiate and complete the communication connection establishment process with the controlled device. This device improves the system's reliability and maintainability by decomposing functions into dedicated modules. The clear responsibilities of each module allow for independent optimization and efficient execution of tasks such as detection and connection. The specialized design of the contact detection module 202 ensures high detection sensitivity and low power consumption, laying the foundation for zero standby power consumption of the entire system. The mode switching and connection module 204 binds the wake-up and connection actions into an automated, continuous process, eliminating user waiting at the system level and achieving a seamless ready experience.

[0144] In some embodiments, the remote control device may optionally include: an instruction sending module, configured to, in active mode, send function instructions corresponding to function keys on the remote control to the controlled device via a communication connection in response to triggering of function keys on the remote control; and a sleep control module, configured to exit active mode and enter low-power mode in response to detecting that a human body has lost contact with the remote control.

[0145] In this embodiment, the remote control device also includes a command sending module and a sleep control module. The command sending module is the main execution unit in the active mode. When a user triggers a function button on the remote control, this module responds by converting the electrical signal of the function button into corresponding function command data that can be recognized by the controlled device, and then sends this function command data to the controlled device through the established communication connection. The sleep control module is the energy-saving management unit of the device. It continuously monitors the contact status. When it detects that the human body has disconnected from the remote control, for example, when the capacitance value returns to the reference level, the module generates a control command to cause the remote control to exit the active mode, shut down the power supply to most functional circuits, and re-enter the low-power mode. This device improves system reliability and maintainability by decomposing functions into dedicated modules. The clear responsibilities of each module allow for independent optimization and efficient execution of tasks such as command processing and power management. The independent existence of the command sending module ensures the immediacy and stability of control command generation and transmission. The automatic management of the sleep control module ensures strict execution of power control strategies, guaranteeing rapid entry into energy-saving mode during any non-use intervals, thereby effectively extending battery life at the system architecture level.

[0146] In some embodiments, the remote control device may optionally include a receiving and display module for receiving status information of the controlled device from the controlled device and displaying the status information on the display screen of the remote control.

[0148] In some embodiments, the remote control device may optionally include a filtering and reassembly module for deduplicating and reassembling the received duplicate first broadcast data packets to restore the complete status information of the controlled device.

[0149] In some embodiments, the receiving and display module is optionally further configured to display function instructions on the display screen of the remote controller; receive the execution result of the function instructions from the controlled device; and display the execution result on the display screen.

[0150] In some embodiments, optionally, the sleep control module is further configured to exit the activation mode and enter the low power mode in response to detecting that the human body and the remote control have not been disconnected and that the remote control has been inactive for a preset time.
