Description

Technical Field

[0001] This invention belongs to the field of kitchen appliance technology, specifically relating to an interrupt wake-up system, control method, and smart stove that integrates a Bluetooth module and a display module. Background Technology

[0002] Against the backdrop of the rapid upgrading of the smart home industry, household cooktops (such as gas stoves) are gradually moving away from their traditional, single cooking function and undergoing a profound transformation towards intelligence, wireless connectivity, and convenient control. Currently, Bluetooth wireless communication has become a standard feature in smart gas stoves. By integrating a Bluetooth module into the device, it enables diverse intelligent functions such as remote flame control via mobile app, real-time data synchronization, intelligent fault reporting, and timed start / stop, effectively improving the user experience and facilitating intelligent maintenance for manufacturers. Furthermore, as the intelligent upgrade continues, modules for user interaction, such as touch controls and digital status displays, are gradually being integrated into cooktops.

[0003] However, among the mainstream smart gas stove products on the market, the display module and Bluetooth module generally adopt a hardware separate layout design. The two modules are laid out on separate boards and independently selected and developed. This has inherent design shortcomings in many aspects such as overall structure assembly, power distribution, and signal docking, making it difficult to adapt to the harsh operating conditions such as the small gas stove cavity, large temperature and humidity fluctuations, and dry battery power supply. For example, the separate layout of the dual modules results in low device integration and wasted space and wiring resources. The display module and Bluetooth module need to be fixed with separate circuit boards, which compresses and occupies the limited installation space around and below the stove valve body. The separate setting of the display module and Bluetooth module also requires separate control logic design, lacking integrated power consumption design and sleep coordination management logic. The power consumption of the whole machine is relatively high under static conditions. The display module is often kept in standby mode with the screen constantly lit or refreshed at high frequency. The Bluetooth module mostly relies on software polling to monitor wake-up commands. There is no matching hierarchical sleep strategy for the two modules, so they cannot enter a low-power sleep mode during idle periods. The static power consumption of the whole machine remains high. Gas stoves mostly rely on disposable dry batteries as the power source for the whole machine. Excessive power consumption will significantly shorten the battery replacement cycle, making it difficult to achieve the product's long battery life design goal and failing to meet the low-cost and low-maintenance usage requirements of household stoves.

[0004] To solve the above problems, it is necessary to design an interrupt wake-up system and control method for a highly integrated Bluetooth module and display module that is low in power consumption and applied to cooktops. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide an interrupt wake-up system, control method, and smart stove with high integration and low power consumption of integrated Bluetooth module and display module.

[0006] This invention provides an interrupt wake-up system integrating a Bluetooth module and a display module, comprising a display module unit and a Bluetooth module unit, wherein the Bluetooth module unit is integrated inside the display module unit, and the display module unit is electrically and signal-connected to the Bluetooth module unit;

[0007] The display module unit includes a display MCU module, a display driver circuit, and a display panel. The display driver circuit is integrated in the display MCU module. The display MCU module and the display driver circuit control the operating conditions of the display panel. The display MCU module is provided with a first communication pin, and the Bluetooth module unit is provided with a second communication pin. The first communication pin and the second communication pin are connected to establish a UART bidirectional communication link between the display module unit and the Bluetooth module unit for bidirectional data interaction and bidirectional mutual wake-up.

[0008] Preferably, the Bluetooth module unit is provided with an external antenna module, an interrupt receiving pin, and an output pin. The external antenna module is used to receive remote signals, and the interrupt receiving pin is used to receive an interrupt wake-up signal. The Bluetooth module unit is in a deep sleep state under normal conditions. When the external antenna module or the interrupt receiving pin receives an interrupt wake-up signal, the Bluetooth module unit sends an interrupt signal to the display module unit through the output pin to wake up the deeply sleep-bound display module unit and establish a bidirectional communication link with it. When the display module unit establishes a connection with the Bluetooth module unit in deep sleep, the display module unit sends an interrupt signal to the interrupt receiving pin of the Bluetooth module unit to wake up the Bluetooth module unit and establish a bidirectional communication link with it.

[0009] Preferably, the interrupt wake-up system further includes a touch wake-up adapter unit. The display module unit is provided with a first interrupt interface. The output terminal of the touch wake-up adapter unit is connected to the first interrupt interface, and the input terminal of the touch wake-up adapter unit is connected to external touch wake-up hardware. The display module unit is in a deep sleep state under normal conditions. When the external touch wake-up hardware wakes up the display module unit, the display module unit outputs display functions or other setting functions. If it is necessary to connect to the Bluetooth module unit, an interrupt signal is sent to the Bluetooth module unit through the output pin of the display module unit, and a bidirectional communication link is established with the Bluetooth module unit.

[0010] Preferably, the touch wake-up adapter unit is further provided with a buffer circuit, which is connected to the input terminal of the touch wake-up adapter unit and is used to filter out noise from the signal input by the external touch wake-up hardware to obtain a stable wake-up signal and transmit it to the display module unit.

[0011] Preferably, the interrupt wake-up system integrating the Bluetooth module and the display module further includes a power supply unit and a power consumption isolation unit. The input terminal of the power consumption isolation unit is connected to the power supply unit, and the output terminal is connected to the display module unit, for supplying power to the display module unit and the Bluetooth module unit.

[0012] Preferably, the power consumption isolation unit includes a boost module and a power consumption control switch. The boost module is connected to the power supply unit and is used to boost the output voltage of the power supply unit to 3.3V or 5V before supplying power to the power consumption module. The power consumption control switch is located between the boost module and the display module unit. The power consumption control switch is normally open, and retains the interrupt wake-up detection power supply function in the open state. When the display module unit or the Bluetooth module unit is woken up, the power consumption control switch is set to the connected state and supplies power to the power consumption module normally.

[0013] Preferably, the interrupt wake-up system further includes a main controller unit, and the power consumption isolation unit is provided with two independent power supply branches. The first independent power supply branch is electrically connected to the display module unit, and the second independent power supply branch is electrically connected to the main controller unit. The power supply unit supplies power to the display module unit and the Bluetooth module unit respectively from the 3.3V power directly input from the main controller unit.

[0014] The main controller unit is also connected to the display module unit via a bidirectional communication link.

[0015] The present invention also provides a bidirectional interrupt wake-up control method based on a Bluetooth module and a display module, which is applied to the interrupt wake-up system integrating a Bluetooth module and a display module as described in any of the above claims, and includes the following steps:

[0016] Step S1: System Initialization: After power-on, the display module unit and the Bluetooth module unit establish a UART bidirectional communication link. The display module unit connects to and adapts to the external touch wake-up hardware. The display module unit presets the wake-up priority, where the touch wake-up priority is greater than the remote wake-up priority. The display module unit configures interrupt wake-up and emergency parameters. The power consumption isolation unit completes the boost initialization parameter settings. After the display module unit and the Bluetooth module unit complete the initialization settings, they are configured to enter deep sleep mode.

[0017] Step S2: Normal Sleep Collaborative Control: The display module unit and the Bluetooth module unit retain the interrupt detection function in deep sleep mode; the power control switch of the power isolation unit remains in the off state, and is reserved to power the interrupt detection circuit and the touch wake-up adapter unit.

[0018] Step S3: Bidirectional Interrupt Wake-up and Communication: After the display module unit is woken up by the touch signal, the display module unit outputs display functions or other setting functions. When it is necessary to connect to the Bluetooth module unit, the display module unit sends an interrupt signal to the interrupt receive pin of the Bluetooth module unit to wake up the Bluetooth module unit from deep sleep; or the Bluetooth module unit is woken up remotely, and the Bluetooth module unit sends an interrupt signal to the display module unit through its output pin to wake up the display module unit from deep sleep; after the display module unit and the Bluetooth module unit are woken up synchronously, the two modules establish a bidirectional communication link.

[0019] Step S4: Wake-up conflict control: When multiple wake-up signals are triggered simultaneously, they are executed according to the preset wake-up priority, and low-priority wake-up signals are temporarily stored; if the Bluetooth module unit and the display module unit do not have a valid operation command after being woken up, the Bluetooth module unit and the display module unit will automatically enter a deep sleep state after 3-5 seconds.

[0020] Step S5: Emergency Handling: When the display module unit or Bluetooth module unit detects an abnormal wake-up signal or communication abnormality, it triggers an emergency wake-up and attempts to reconnect 3-5 times; if the reconnection fails, the display module unit enters standby mode, and the Bluetooth module unit records the abnormality log and enters sleep mode.

[0021] Step S6: Loop Control: Repeat steps S2-S5 to perform closed-loop control of hibernation-wake-communication-hibernation.

[0022] Preferably, in step S1, the preset wake-up priority also includes main controller wake-up, and the touch wake-up priority > main controller wake-up priority > remote wake-up priority, wherein touch wake-up, main controller wake-up, and remote wake-up are respectively:

[0023] S11: Touch Wake-up: The touch signal from the external touch wake-up hardware is filtered for noise by the touch wake-up adapter unit and then sent to the display module unit to wake up the display MCU module. The display MCU module controls the power consumption control switch to turn on and controls the power consumption isolation unit to start voltage boost and power supply. The display module unit establishes a UART bidirectional communication link with the Bluetooth module unit and wakes up the Bluetooth module unit. The display module unit interacts with the Bluetooth module unit and / or with the main controller unit. When the data interaction is completed, the display module unit and the Bluetooth module unit enter sleep mode synchronously.

[0024] S12: Remote Wake-up: The Bluetooth module unit wakes up after receiving a remote command. The Bluetooth module unit sends an interrupt signal to wake up the display module unit. The display module unit connects the display panel and supplies power. The Bluetooth module unit and the display module unit establish a two-way communication link and execute the remote command. After the remote command operation is completed, the Bluetooth module unit and the display module unit enter sleep mode synchronously.

[0025] S13: Main controller wake-up: After receiving the interrupt wake-up signal, the main controller unit establishes a bidirectional communication link with the display module unit. The main controller unit wakes up the display module unit and sends operation commands. The display module unit interacts with the Bluetooth module unit. After the display module unit and the Bluetooth module unit complete the command operation, the Bluetooth module unit and the display module unit enter sleep mode synchronously.

[0026] The present invention also provides a smart stove, which uses the bidirectional interrupt wake-up control method based on Bluetooth module and display module as described above.

[0027] Compared with existing technologies, the interrupt wake-up system and control method integrating the Bluetooth module and display module in this solution have at least the following advantages:

[0028] 1. This solution provides an interrupt wake-up system integrating a Bluetooth module and a display module. By integrating the Bluetooth module unit into the display module unit, compared to the traditional separate structure where the display and Bluetooth circuit boards are assembled separately, the hardware structure is simplified, reducing the space occupied inside the stove. Correspondingly, the number and layout of external leads for the display module unit and Bluetooth module unit are simplified. In environments where the stove is subject to long-term oil fume adhesion and large temperature fluctuations, it can effectively reduce the risk of short circuits due to moisture in the insulation between circuits and corrosion of circuits by oil fumes. It also reduces electromagnetic interference from the external environment to the communication lines and signal links, thus improving the long-term stability of the entire system.

[0029] 2. This solution provides an interrupt wake-up system integrating Bluetooth and display modules, further featuring a power isolation unit and sleep mode co-control. Under normal operating conditions, i.e., when the stove is in standby mode and not in use, the display module and Bluetooth module are in low-power sleep mode. The system only maintains power supply to the interrupt signal detection branch. Compared to traditional smart stoves, it does not perform high-power-consuming operations such as screen refresh, Bluetooth RF always-on, and software polling and inspection, which significantly reduces the system's power consumption. For stoves powered by dry cell batteries, it can achieve a long battery life.

[0030] 3. The bidirectional interrupt wake-up control method based on the Bluetooth module and display module provided in this solution applies the above-mentioned interrupt wake-up system to realize dual wake-up control of the Bluetooth module unit and the display module unit. The dual wake-up has strong coordination, realizes the synchronization of touch and remote wake-up, and avoids communication failure by preset wake-up priority; and adopts interrupt-triggered wake-up, which has fast response speed and low daily power consumption.

[0035] It should be noted that when one element is considered to be "connected" to another element, it can be directly connected to and integrated with the other element, or there may be an intervening element present. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0036] Please refer to Figure 1This invention provides an interrupt wake-up system integrating a Bluetooth module and a display module, suitable for low-power smart devices such as smart gas stoves powered by dry batteries. It achieves a highly integrated layout of display and Bluetooth wireless communication functions, while also providing bidirectional interrupt wake-up and sleep-coordination capabilities. The system includes a display module unit and a Bluetooth module unit, with the Bluetooth module unit integrated within the display module unit. The display module unit and the Bluetooth module unit are electrically and signal-connected, enabling bidirectional signal transmission, status interaction, and mutual wake-up control. In this embodiment, the display module unit includes a display MCU module, a display driver circuit, and a display panel. The display driver circuit is integrated within the display MCU module, and the display MCU module and display driver circuit control the operating conditions of the display panel. As can be understood, the MCU is a microcontroller; the display MCU module is electrically connected to the display driver circuit, which outputs drive signals to precisely control the display panel's operation, including lighting, extinguishing, parameter display, and interface switching, thus achieving a visual display of the device's status. The display MCU module has a first communication pin, and the Bluetooth module unit has a second communication pin. The first and second communication pins are connected to establish a UART bidirectional communication link between the display module unit and the Bluetooth module unit, enabling bidirectional data exchange and mutual wake-up. As can be understood, a UART bidirectional communication link refers to a connection method that enables bidirectional, asynchronous, serial data transmission between two devices via the UART serial port protocol. UART stands for Universal Asynchronous Receiver / Transmitter. Based on this communication link, the display module unit and the Bluetooth module unit can achieve bidirectional data exchange, status synchronization, and bidirectional mutual wake-up, effectively solving the technical defects of communication delay and asynchronous wake-up in traditional separate modules.

[0037] In this embodiment, the Bluetooth module unit is equipped with an external antenna module, an interrupt receive pin, and an output pin. The external antenna module is used to receive remote signals, and the interrupt receive pin is used to receive interrupt wake-up signals. Under normal conditions, the Bluetooth module unit is in a deep sleep state. When the external antenna module or the interrupt receive pin receives an interrupt wake-up signal, the Bluetooth module unit wakes up the display module unit from its deep sleep state by sending an interrupt signal to the display module unit via the output pin and establishes a bidirectional communication link with it. It can be understood that the external antenna module is responsible for receiving remote wireless control signals from the mobile terminal, realizing the remote control function of the stove, while the interrupt receive pin serves as the wake-up trigger port for the Bluetooth module unit. Under normal operating conditions, the Bluetooth module unit maintains a deep sleep state, disabling high-power functions such as RF transmission, high-frequency detection, and redundant protocol stacks, retaining only the basic link layer handshake and interrupt signal detection functions. When the external antenna module receives a remote control command or the interrupt receive pin detects a valid wake-up signal, the Bluetooth module unit is woken up and quickly establishes a bidirectional communication link with the display module unit, waking up the display module unit to work collaboratively. Similarly, when the display module unit needs to establish a connection with the Bluetooth module unit which is in a deep sleep state, the display module unit sends an interrupt signal to the interrupt receive pin of the Bluetooth module unit to wake up the Bluetooth module unit and establish a two-way communication link with it.

[0038] Furthermore, the Bluetooth module unit includes a Bluetooth chip module and a link layer sleep module. The Bluetooth chip module and the link layer sleep module are electrically connected. The link layer sleep module is used to control the Bluetooth chip module to enter a deep sleep state under normal conditions. Understandably, when the link layer sleep module controls the Bluetooth module unit to enter a deep sleep state under normal conditions, the Bluetooth chip module only retains interrupt reception and link layer handshake functions. Interrupt reception means that under normal conditions, the Bluetooth chip module does not need to repeatedly poll; it only processes data when it is available. The link layer handshake function refers to the communication interaction logic of the Bluetooth module unit's basic connection verification, status interaction, and keep-alive interaction. After the Bluetooth chip module enters deep sleep and disables data transmission, reception, and radio frequency broadcasting, it is woken up by an external interrupt. The link layer handshake only performs lightweight, low-power low-level link interaction and does not handle business data transmission. When the controller unit initiates a wake-up or connection request, the Bluetooth module unit's link layer sleep module completes the simplest response interaction, that is, confirms that it can respond normally and that the link channel is valid, completes the initial docking, and paves the way for subsequent communication; or in the sleep state, it periodically or as needed performs a very simple response to detect whether the link layer is in a normal connectivity state, to avoid the link being dead or disconnected without being detected, and only transmits very short low-level status frames throughout the process, with very low power consumption.

[0039] In this embodiment, the interrupt wake-up system integrating the Bluetooth module and the display module further includes a touch wake-up adapter unit. The display module unit is equipped with a first interrupt interface, the output of the touch wake-up adapter unit is connected to the first interrupt interface, and the input of the touch wake-up adapter unit is connected to the external touch wake-up hardware to achieve standardized access of touch signals. The display module unit is normally in a deep sleep state. When the external touch wake-up hardware wakes up the display module unit, the display module unit outputs display functions or other setting functions; that is, the display module unit first lights up the screen for user operation. If a connection to the Bluetooth module unit is required, the display module unit sends an interrupt signal to the Bluetooth module unit through its own output pin to wake up the Bluetooth module unit and establish a bidirectional communication link with it. Under normal circumstances, both the display module unit and the Bluetooth module unit remain in a deep sleep state, retaining only the interrupt detection function. When the user triggers the external touch wake-up hardware to generate a touch signal, the touch wake-up adapter unit processes the signal and accurately wakes up the display module unit. Subsequently, the display module unit wakes up the Bluetooth module unit by sending an interrupt signal to the interrupt receiving pin of the Bluetooth module unit, achieving collaborative startup and data interaction between the two modules.

[0040] In this embodiment, the touch wake-up adapter unit also includes a buffer circuit. The buffer circuit is connected to the input terminal of the touch wake-up adapter unit and is used to filter out noise from the signal input by the external touch wake-up hardware, obtaining a stable wake-up signal and transmitting it to the display module unit. It is understood that interference signals such as ignition pulse interference, power grid noise, and radio frequency glitches exist in the working environment of the stove. The buffer circuit can filter and shape the input raw touch signal, remove noise, and optimize the waveform, eliminating invalid interference signals and outputting a stable, standard, and valid wake-up signal for transmission to the display module unit. This avoids false wake-ups and wake-up failures caused by interference signals at the hardware level, significantly improving the stability and anti-interference capability of touch wake-up.

[0041] In a preferred embodiment, the interrupt wake-up system integrating the Bluetooth module and display module further includes a power supply unit and a power consumption isolation unit. The input terminal of the power consumption isolation unit is connected to the power supply unit, and the output terminal is connected to the display module unit, for supplying power to the display module unit and the Bluetooth module unit. It is understood that the power supply unit in the cooktop industry is often a 1.5V dry cell battery, which needs to provide power to the entire system and is also connected to the pulse ignition circuit and the gas valve drive circuit respectively to directly supply power to them. The power consumption isolation unit is located between the power supply unit and the display module unit to isolate the power supply circuit of the power supply unit, forming multiple power supply branches to different modules. This power supply branch isolation achieves isolation between different modules and branches, preventing abnormalities or malfunctions in one module from affecting other modules, thereby improving the safety and stability of the system.

[0042] In this embodiment, the power consumption isolation unit includes a boost module and a power consumption control switch. The boost module is connected to the power supply unit and is used to boost the output voltage of the power supply unit to 3.3V or 5V to supply power to the power consumption module. The power consumption control switch is located between the boost module and the display module unit. The power consumption control switch is normally open, but retains the interrupt wake-up detection power supply function in the open state. When the display module unit or Bluetooth module unit is woken up, the power consumption control switch is set to the connected state and supplies power to the power consumption module normally. For example, the boost module has a built-in boost chip and boost circuit, such as a DC-DC boost chip, specifically referring to DC-DC boost (Direct Current to Direct Current), which stably converts a lower DC voltage into a higher DC voltage. In gas stove products, dry batteries are generally used as the starting power source, but the voltage of dry batteries is generally a low voltage of 1.5V. When it is necessary to supply power to components such as chips, display modules, or relays, the voltage needs to be boosted to 3.3V or 5V to meet normal operating conditions. The power control switch is located between the boost module and the display module, specifically at the rear end of the boost module. Normally, the power control switch remains open. In this open state, the system only supplies power to low-power components or circuits such as the interrupt detection circuit, touch wake-up adapter unit, and link layer handshake, maintaining microamplitude standby power consumption for the entire system. When the display module or Bluetooth module receives a valid wake-up signal and is triggered to wake up, the power control switch simultaneously closes, providing power to each functional module for normal operation and ensuring the normal functioning of display, communication, and data interaction.

[0043] In a preferred embodiment, the interrupt wake-up system integrating the Bluetooth module and the display module further includes a main controller unit. The power isolation unit has two independent power supply branches. The first independent power supply branch is electrically connected to the display module unit, and the second independent power supply branch is electrically connected to the main controller unit. The power supply unit supplies power to the display module unit and the Bluetooth module unit respectively from the 3.3V power directly input from the main controller unit. It can be understood that the main controller unit is the main controller of the system, enabling control over each module. The first and second independent power supply branches achieve electrical isolation between the main controller unit and the display module unit, avoiding problems such as power supply crosstalk, voltage fluctuations, and fault propagation between the two module units. In this embodiment, the main controller unit also has a bidirectional communication link with the display module unit. It can be understood that the main controller unit has connection pins for signal connection to the display module unit, used to implement interactive functions such as issuing main control commands, transmitting device status, reporting fault information, and functional collaborative control, achieving collaborative control of multiple units within the entire system.

[0044] Please refer to Figure 2The present invention also provides a bidirectional interrupt wake-up control method based on a Bluetooth module and a display module, which is applied to an interrupt wake-up system integrating a Bluetooth module and a display module as described above, and includes the following steps:

[0045] Step S1: System Initialization: After power-on, the display module unit and Bluetooth module unit establish a UART bidirectional communication link. The display module unit connects to and adapts to the external touch wake-up hardware. The display module unit presets wake-up priorities, where touch wake-up priority > remote wake-up priority. The display module unit configures interrupt wake-up and emergency parameters. The power isolation unit completes the boost initialization parameter settings. After the display module unit and Bluetooth module unit complete the initialization settings, they are configured to enter deep sleep mode. It is understood that the power supply unit supplies power to the entire system, and the power isolation unit completes initialization work such as boost parameter calibration and power supply threshold configuration. The power isolation unit boosts the power supply voltage to 3.3V or 5V and forms different independent power supply branches. After the system powers on, the display module unit and Bluetooth module unit automatically establish a stable UART bidirectional communication link, completing communication parameter matching and link binding. Simultaneously, the display module unit automatically completes interface adaptation and signal calibration with the external touch wake-up hardware. The display module unit also uniformly configures interrupt wake-up parameters, communication thresholds, and emergency retry parameters. After all initialization configurations are completed, the display module unit and Bluetooth module unit are configured to enter deep sleep mode, entering a low-power standby state.

[0046] Step S2: Normal Sleep Collaborative Control: The display module unit and Bluetooth module unit retain interrupt detection functionality in deep sleep mode; the power control switch of the power isolation unit remains open, reserving power for the interrupt detection circuit and touch wake-up adapter unit. Understandably, during normal system operation, the display module unit and Bluetooth module unit always maintain a deep sleep state, retaining only core low-power functions such as interrupt signal detection and link layer handshake, while shutting down other high-power units. Simultaneously, the power control switch of the power isolation unit remains open, providing power only to necessary detection modules such as the interrupt detection circuit and touch wake-up adapter unit, minimizing the overall static standby power consumption and meeting the long-term battery life requirements.

[0047] Step S3: Bidirectional Interrupt Wake-up and Communication: After the display module unit is woken up by touch, it outputs display functions or other setting functions. When the display module unit needs to connect to Bluetooth, it sends an interrupt signal to the interrupt receive pin of the Bluetooth module unit to wake up the Bluetooth module unit from deep sleep; or it wakes up the Bluetooth module unit remotely, and the Bluetooth module unit sends an interrupt signal to the display module unit through its output pin to wake up the display module unit from deep sleep. After the display module unit and the Bluetooth module unit are woken up synchronously, the two modules establish bidirectional data interaction. It can be understood that the system supports a bidirectional linkage wake-up mechanism, including the display module unit waking up the Bluetooth module unit and the Bluetooth module unit waking up the display module unit. Specifically, the former wakes up the display module unit through an external touch signal, and the display module unit can output an interrupt wake-up signal after being triggered, triggering the Bluetooth module unit to complete the collaborative wake-up; the latter is triggered when the Bluetooth module unit receives a wireless command from a remote terminal and wakes up the display module unit in reverse through an interrupt signal. After the two modules are woken up synchronously, bidirectional data interaction is established, completing tasks such as command parsing, function execution, and status feedback.

[0048] Step S4: Wake-up Conflict Management: When multiple wake-up signals are triggered simultaneously, they are executed according to the preset wake-up priority, while lower-priority wake-up signals are temporarily stored. If the Bluetooth module unit and display module unit are woken up but no valid operation command is received, they will automatically enter deep sleep mode after 3-5 seconds. Understandably, if touch wake-up, remote wake-up, or other wake-up signals are triggered simultaneously during operation, the response action will be executed according to the preset priority logic, and lower-priority wake-up signals will be temporarily stored and queued, responding sequentially after the current high-priority task is completed. This avoids system instability, command loss, and module freezing caused by multiple signal conflicts. Furthermore, an intelligent sleep fallback mechanism is set up. If no valid operation command or data interaction task is detected within a preset 3-5 seconds after the Bluetooth module unit and display module unit are successfully woken up, they will automatically enter deep sleep mode, avoiding unnecessary standby power consumption and further optimizing overall power consumption control.

[0049] Step S5: Emergency Handling: When the display module unit or Bluetooth module unit detects an abnormal wake-up signal or communication abnormality, it triggers an emergency wake-up and attempts to reconnect 3-5 times. If the reconnection fails, the display module unit enters a standby state, and the Bluetooth module unit records an abnormality log and enters a sleep state. Understandably, the system will check the integrity of the wake-up signal, the UART communication link status, and the power supply status of each module. When faults such as wake-up signal distortion, signal interruption, communication packet loss, or link abnormality are detected, the emergency reconnection mechanism is automatically triggered, continuously performing 3-5 interrupted wake-up retries and communication link reconstruction operations. Multiple retries eliminate intermittent faults caused by momentary interference. If multiple retries still fail to establish normal communication and the fault cannot be eliminated, the display module unit is controlled to enter a low-power standby state, while the Bluetooth module unit records the fault code and abnormality log for subsequent equipment maintenance and tracing. Subsequently, both module units simultaneously enter a sleep state to prevent the fault from continuing to cause power consumption and system abnormalities.

[0050] Step S6: Loop Control: Repeat steps S2-S5 to perform closed-loop control of sleep-wake-communication-sleep. By forming a closed-loop intelligent control logic, the device can achieve stable, low-power, and uninterrupted operation around the clock, ensuring the continuity and reliability of the whole machine control.

[0051] In this embodiment, in step S1, the preset wake-up priority also includes main controller wake-up, and the touch wake-up priority > main controller wake-up priority > remote wake-up priority, wherein touch wake-up, main controller wake-up, and remote wake-up are respectively:

[0052] S11: Touch Wake-up: The touch signal from the external touch wake-up hardware is filtered for noise by the touch wake-up adapter unit and then sent to the display module unit to wake up the display MCU module. The display MCU module controls the power consumption control switch to turn on and controls the power consumption isolation unit to start voltage boosting and power supply. The display module unit establishes a UART bidirectional communication link with the Bluetooth module unit and wakes up the Bluetooth module unit. The display module unit interacts with the Bluetooth module unit and / or with the main controller unit. After the data interaction is completed, the display module unit and the Bluetooth module unit enter sleep mode synchronously. In essence, when a user triggers the external touch wake-up hardware, the original touch signal is first input to the touch wake-up adapter unit, where internal buffer circuitry filters out noise and shapes the signal, outputting a standard and stable wake-up signal which is then transmitted to the display module unit. After being woken up, the display MCU module controls the power consumption control switch to close and turn on, starting the power consumption isolation unit to boost voltage and provide normal operating voltage for all functional modules. The display module unit establishes a bidirectional communication link with the Bluetooth module unit and synchronously wakes up the Bluetooth module unit, completing data interaction between the two modules as needed, or linking with the main controller unit to complete device function operations. After all data interaction and function command execution are completed, the display module unit and the Bluetooth module unit simultaneously shut down their working modes and enter a deep sleep state.

[0053] S12: Remote Wake-up: The Bluetooth module unit wakes up after receiving a remote command. It sends an interrupt signal to wake up the display module unit, which then powers on the display panel. A bidirectional communication link is established between the Bluetooth and display modules to execute the remote command. After the remote command operation is completed, both the Bluetooth and display modules enter sleep mode synchronously. In essence, the Bluetooth module unit wakes up autonomously after receiving a remote control command from the mobile terminal via its external antenna module, and then outputs a hardware interrupt signal to the display module unit, triggering it to wake up synchronously and power on the display panel and illuminate the interface. The Bluetooth and display modules establish a bidirectional communication link, collaboratively parse and execute remote control commands, and perform operations such as remote fire control, status query, parameter setting, and fault reporting.

[0054] S13: Main controller wake-up: After receiving the interrupt wake-up signal, the main controller unit establishes a bidirectional communication link with the display module unit. The main controller unit wakes up the display module unit and sends operation commands. The display module unit interacts with the Bluetooth module unit. After the display module unit and the Bluetooth module unit complete the command operation, the Bluetooth module unit and the display module unit enter sleep mode synchronously.
