Description

Technical Field

[0001] This application relates to the field of electrical stimulation therapy equipment technology, and more specifically, to an electrical stimulation control system, method, and device based on a dual-stimulation source architecture. Background Technology

[0002] Electrical stimulation therapy devices are a type of health therapy device that applies low- or mid-frequency electrical pulse signals to the ear area through specific electrodes to regulate nerve or muscle activity, relieve fatigue, or assist in treatment. Existing ear electrical stimulation products are generally classified into wired and wireless types based on their signal transmission and control methods. Their operational logic is mostly based on a centralized control model of "single host – single slave": the host has a built-in unique stimulation signal generation unit that sends parameter commands to the electrode output component at the earpiece end via a wired cable or wireless link such as Bluetooth. The earpiece itself only acts as a signal receiver and conduction load and does not participate in the independent generation of waveforms.

[0003] While some existing technologies offer compatibility between wired and wireless modes, these so-called dual-mode devices only achieve simple interface-level compatibility. A unified scheduling logic and state inheritance mechanism are lacking between the wired and wireless modes. This failure to achieve distributed collaboration and offline autonomy between devices results in significant shortcomings in flexibility, reliability, and user experience, making it difficult to cover users' diverse and highly flexible physiotherapy needs across all scenarios. Summary of the Invention

[0004] To address the aforementioned technical problems, this application discloses an electrical stimulation control system, method, and device based on a dual-stimulation source architecture. By deploying independent stimulation modules in both the remote controller and the ear stimulator, and coordinating them with unified scheduling logic, it achieves dual-mode collaborative output, seamless scene switching, and independent autonomous operation of the ear stimulator after it is disconnected from the host computer. Specifically, the technical solution of this application is as follows: In a first aspect, this application discloses an electrical stimulation control system based on a dual-stimulatory-source architecture, comprising: The remote control is equipped with a first stimulation module, which is used to independently generate a first electrical stimulation signal in wired mode. A wired earphone is pluggable to the wired interface of the remote control. The wired earphone is provided with a first stimulation electrode, which is used to transmit the first electrical stimulation signal to the human ear. An ear stimulator, which includes a second stimulation module, which is used to independently generate a second electrical stimulation signal in wireless or offline mode. The remote control and the ear stimulator are connected via a wireless communication link to achieve bidirectional sharing and synchronization of status data; The control system is configured to use distributed scheduling logic, allowing only one of the first stimulation module or the second stimulation module to output an electrical stimulation signal at any given time. In offline mode, the ear stimulator is detached from the remote control and independently controls the generation of the second electrical stimulation signal based on locally stored historical parameters.

[0005] In some embodiments, the remote control specifically includes: a first Bluetooth module, a first power management module, a display module, and a screen driver integrated circuit; The first Bluetooth module is communicatively connected to the first stimulation module and the screen driver integrated circuit via a first universal asynchronous transceiver. The first stimulation module is used to receive the first electrical stimulation parameters sent by the first Bluetooth module through the first universal asynchronous transceiver, and generate the first electrical stimulation signal; The screen driver integrated circuit is used to display the working mode, stimulation level, battery level, and connection status; The first power management module provides regulated power to each module and is controlled by the first Bluetooth module to perform power-on or power-off operations.

[0006] In some implementations, the wired interface is a TYPE-C interface; The wired interface serves as an output channel in wired mode, used to transmit the first electrical stimulation signal generated by the first stimulation module to the wired earphone; the wired interface also serves as a charging input channel, providing charging input to the first power management module.

[0007] In some embodiments, the ear stimulator specifically includes a second Bluetooth module, a second stimulation electrode, a button module, and a second power management module; The second Bluetooth module communicates with the second stimulation module via a second universal asynchronous transceiver. The second stimulation module is used to receive the second electrical stimulation parameters transmitted by the second Bluetooth module through the second universal asynchronous transceiver, and generate the second electrical stimulation signal; The second stimulation electrode is used to transmit the second electrical stimulation signal to the human ear; The button module provides local control signals to the second Bluetooth module; The second power management module provides regulated power to each module of the ear stimulator and is controlled by the second Bluetooth module to perform power-on or power-off operations.

[0008] In other embodiments, the remote control and the ear stimulator are each provided with a non-volatile storage unit for synchronously storing the user's historical physiotherapy prescriptions, electrical stimulation parameters, and usage logs; The electrical stimulation parameters include the frequency, intensity, and duty cycle of the electrical stimulation signal.

[0009] Secondly, this application also discloses an electrical stimulation control method based on a dual-stimulatory-source architecture, wherein the control method is implemented based on the control system described in any of the above embodiments; including: The remote control detects whether the wired headphones are connected to the wired interface; When the wired headphones are detected to be connected, the remote control activates the first stimulation module to generate the first electrical stimulation signal and outputs it through the wired interface. At the same time, it sends a lockout command to the ear stimulator through the wireless communication link, so that the second stimulation module enters a dormant standby state and synchronizes the current electrical stimulation parameters in real time. When the wired headphones are not connected, the remote control sends a start command to the ear stimulator through the wireless communication link. The ear stimulator receives and responds to the start command, and the second stimulation module locally generates the second electrical stimulation signal and outputs it through the second stimulation electrode. At the same time, the first stimulation module enters a sleep standby state and synchronizes the current electrical stimulation parameters in real time. When the wireless communication link is interrupted, the ear stimulator automatically switches to offline mode after disconnecting from the remote control. Based on the historical parameters stored locally, it independently controls the second stimulation module to continuously generate the second electrical stimulation signal, and the intensity can be adjusted and the start / stop can be controlled by local buttons.

[0010] In some implementations, the ear stimulator continuously monitors the wireless signal in offline mode. When a pairing request from the remote control is detected and the signal strength is higher than a preset threshold, the ear stimulator exits offline mode and re-establishes the connection.

[0011] Optionally, after the ear stimulator re-establishes a wireless connection with the remote controller, the ear stimulator transmits the usage log stored during the offline phase and the current changes in electrical stimulation parameters back to the remote controller; the remote controller merges the offline data and local data and synchronously updates the storage unit of the ear stimulator, completing bidirectional data synchronization.

[0012] In other embodiments, the control method further includes: when the ear stimulator is in wireless operation and the remote controller detects the wired headphones being inserted, the remote controller sends a switching command to the ear stimulator; the ear stimulator responds to the switching command by cutting off the output of the second stimulation module and sending the current electrical stimulation parameters to the remote controller; the remote controller enables the first stimulation module to continue outputting according to the current electrical stimulation parameters.

[0013] Thirdly, this application also discloses an electrical stimulation device based on a dual-stimulus source architecture, the electrical stimulation device including the electrical stimulation control system based on the dual-stimulus source architecture described in any of the above embodiments.

[0014] Compared with the prior art, this application has at least one of the following advantages: 1. This application utilizes a distributed dual-stimulation source architecture, deploying independently operating first and second stimulation modules in the remote control and ear stimulator respectively, achieving complete coverage of wired, wireless, and offline modes. The remote control, in conjunction with wired headphones, can achieve stable output in fixed scenarios, while the ear stimulator can independently perform wireless connection and offline self-treatment, without always relying on the host or remote control, significantly improving the flexibility and portability of the device in different usage scenarios.

[0015] 2. This application utilizes a state inheritance mechanism within the architecture's collaborative logic to enable the device to automatically read and directly use historical physiotherapy formulas and intensity parameters stored locally when switching between wired, wireless, and offline modes, eliminating the need for users to repeatedly configure them. Simultaneously, usage logs and parameter changes generated during the offline phase are automatically transmitted back and synchronized to both ends of the storage upon reconnection, achieving a closed-loop data flow and resolving the issues of fragmented parameters and inconsistent user experience inherent in existing devices.

[0016] 3. This application employs a secure interlocking and collaborative mechanism to ensure that only one stimulus module has valid output access at any given time, eliminating the security risk of concurrent dual-source output. This mechanism can still monitor the output module in real time during dynamic processes such as mode switching, wired plugging / unplugging, or Bluetooth disconnection, ensuring user safety and providing reliable underlying support for smooth and seamless switching between multiple modes.

[0017] 4. The ear stimulator described in this application possesses complete offline autonomy after being disconnected from the remote control. When the Bluetooth signal is interrupted or the remote control is turned off, the ear stimulator can automatically retrieve locally stored historical parameters and use its own buttons to turn on / off, adjust intensity, and switch modes, continuing the physiotherapy process without needing to reconnect. This function overcomes the technical limitation of traditional wireless devices that must rely on a host device to operate, greatly enhancing the device's practical value and user experience in outdoor, sports, and other scenarios.

However, those skilled in the art will understand that this application may also be implemented in other embodiments without these specific details.

[0024] It should also be further understood that the term “and / or” as used in this application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the specific implementation methods of this application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0028] In existing technologies, common electrostimulation therapy devices typically adopt a single communication mode architecture design. Either they only support wired connections, meaning the stimulator must be connected to a fixed host or remote control via a physical cable, with the stimulation source inside the host generating waveforms and transmitting them to the earphone electrodes via the cable; or they only support wireless connections, where the ear stimulator acts as a purely passive receiver, relying on wireless links such as Bluetooth to receive real-time commands from a mobile app or dedicated remote control. All parameter adjustments, mode switching, and start / stop control depend on external host commands, and the earphone itself does not have independent waveform generation and decision-making capabilities.

[0029] The few devices with "dual-mode" functionality are essentially just physical switching between wired and wireless communication channels. They do not redeploy the distribution of the stimulus source at the system level. They still only have one stimulus signal generation unit inside. Regardless of whether it is wired or wireless mode, the source of the stimulus signal still depends solely on the host. The earphone does not have the ability to generate waves autonomously and operate independently.

[0030] In practical applications, this existing technical architecture has significant flaws.

[0031] First, the usage scenarios are severely limited. While the wired mode offers stable signal, it restricts user movement. While the wireless mode offers freedom, the main unit or remote control must be carried at all times. Once removed from the main unit, the headphones are completely unable to produce any stimulation output, failing to meet the needs of purely portable scenarios such as sports, going out, or lightweight wearables.

[0032] Second, the so-called dual-mode devices are only simple compatibility at the interface level. There is a lack of unified scheduling logic and state inheritance mechanism between wired and wireless modes. When switching, it is often necessary to re-pair and reset parameters, resulting in a fragmented experience and an inability to achieve a smooth transition between modes.

[0033] Third, security relies on a single control terminal. If the communication between the host and the headset is interrupted or the host is unexpectedly shut down, the stimulation process in wireless mode will immediately terminate, lacking local emergency maintenance capabilities.

[0034] Fourth, user history parameters and physiotherapy records are usually only stored on the host device. When the host device is lost or replaced, personalized configurations are difficult to transfer, and the headphones cannot independently memorize and reuse user habits.

[0035] Overall, existing technologies, due to their use of a single stimulus source and host-dependent architecture, fail to achieve distributed collaboration and offline autonomy between devices, resulting in significant deficiencies in flexibility, reliability, and user experience, making it difficult to cover users' full-scenario, high-degree-of-freedom physiotherapy needs.

[0036] This solution adopts a dual-unit distributed architecture with wired and wireless stimulus sources. The two stimulus generation units are hardware-independent and their waveform generation does not interfere with each other. They rely on unified control logic to achieve collaborative linkage and interlocking, thereby supporting cross-terminal collaborative operation in wired, wireless, and offline scenarios.

[0037] Reference manual attached Figure 1 As shown, one embodiment of an electrical stimulation control system based on a dual-stimulus source architecture according to this application specifically includes: The remote controller 01 has a first stimulation module inside, which is used to independently generate a first electrical stimulation signal in wired mode.

[0038] The wired earphone 03 is pluggably connected to the wired interface of the remote control 01. The wired earphone is provided with a first stimulation electrode, which is used to transmit the first electrical stimulation signal to the human ear.

[0039] The ear stimulator 02 has a second stimulation module inside, which is used to independently generate a second electrical stimulation signal in wireless mode or offline mode.

[0040] The remote control and the ear stimulator are connected via a wireless communication link to achieve bidirectional sharing and synchronization of status data.

[0041] The control system is configured to employ distributed scheduling logic, allowing only one of the first stimulation module or the second stimulation module to output an electrical stimulation signal at any given time.

[0042] In offline mode, the ear stimulator is detached from the remote control and independently controls the generation of the second electrical stimulation signal based on locally stored historical parameters.

[0043] Specifically, the control system mainly consists of three components: a remote control, wired headphones, and an ear stimulator. The remote control, as the core control unit of the system, contains a first stimulation module. This module is specifically designed to independently generate the first electrical stimulation signal in wired operation mode, ensuring stable output in fixed scenarios. The wired headphones connect to the remote control's wired interface via a pluggable connection. These headphones are equipped with first stimulation electrodes, which effectively transmit the first electrical stimulation signal generated by the remote control to the human ear, achieving electrical stimulation therapy output.

[0044] As an independent wearable device, the ear stimulator has a built-in second stimulation module. This module is specifically designed to generate a second electrical stimulation signal in wireless online mode or offline independent mode, so that the ear stimulator still has complete signal generation and output capabilities when it is disconnected from the remote control.

[0045] The remote control and the ear stimulator are connected bidirectionally via a wireless communication link such as Bluetooth. This link is mainly used for bidirectional sharing and synchronization of status data between the two, including the interactive transmission of information such as historical parameters, usage logs and real-time working status.

[0046] The control system adopts a distributed scheduling logic for unified management. The core of this logic is that at any given time, only one of the first stimulation module or the second stimulation module is allowed to output an electrical stimulation signal, thereby avoiding the safety risks caused by dual-source concurrent output.

[0047] In some implementations, the system is also equipped with a safety interlocking mechanism, including dual protection of hardware interlocking loops and software flag interlocking.

[0048] Optionally, the hardware interlocking circuit controls the output enable terminal of the first stimulation module through the level detection signal of the wired interface of the remote controller, and simultaneously controls the output enable terminal of the second stimulation module through the connection status signal of the wireless communication link.

[0049] The software flag interlock maintains an output permission flag in both the remote control and the ear stimulator's control unit. At any given time, only a single stimulation module is allowed to obtain valid output permission. The hardware interlock circuit operates in parallel with the software flag interlock; if any layer of protection determines that the current stimulation module is not authorized to output, the output path of the corresponding stimulation module is forcibly cut off.

[0050] When the system is in offline mode, the ear stimulator operates completely independently of the remote control. At this time, it autonomously controls the second stimulation module to generate the required electrical stimulation signal and output it to the human body based on the historical parameters pre-saved in the local storage unit, without relying on the remote control or external commands.

[0051] Based on the above embodiments, this application discloses another embodiment of an electrical stimulation control system based on a dual-stimulus source architecture, as detailed in the appendix. Figure 2 As shown, the remote control 01 specifically includes: a first Bluetooth module 102, a first power management module 103, a display module 104, and a screen driver integrated circuit 105.

[0052] The first Bluetooth module 102 is communicatively connected to the first stimulation module 106 and the screen driver integrated circuit 105 via a first universal asynchronous transceiver (UART).

[0053] The first stimulation module 106 is used to receive the first electrical stimulation parameters sent by the first Bluetooth module 102 through the first universal asynchronous transceiver and generate the first electrical stimulation signal.

[0054] The screen driver integrated circuit 105 is used to display the working mode, stimulation level, battery level, and connection status.

[0055] The first power management module 103 provides regulated power to each module and is controlled by the first Bluetooth module 102 to perform power-on or power-off operations.

[0056] Specifically, the first Bluetooth module 102 serves as the core control and communication unit of the remote control 01. It establishes communication connections with the first stimulation module 106 and the screen driver IC 105 via a first universal asynchronous transceiver. This module is responsible for establishing a wireless connection with the ear stimulator 02 and sending parameter commands to the first stimulation module 106 via UART, while simultaneously sending display data to the screen driver IC, thus realizing overall command scheduling and data interaction.

[0057] The first stimulation module 106 is used to receive the first electrical stimulation parameters, including frequency, duty cycle and intensity, sent by the first Bluetooth module 102 through the first universal asynchronous transceiver, and independently generate a first electrical stimulation signal that meets the index requirements according to the above parameters, and output it to the wired headphones through the wired interface 108.

[0058] The screen driver integrated circuit 105 receives display data sent by the first Bluetooth module 102 via UART, and drives the display module 104 to refresh after decoding and timing control. This is used to display information such as the current working mode, stimulation level, battery level, and connection status in real time, providing users with an intuitive human-computer interaction interface.

[0059] The first power management module 103 is responsible for the power distribution and management of the whole machine. It is connected to the built-in first lithium battery 101 and provides a stable regulated power supply for the first Bluetooth module 102, the first stimulation module 106 and the screen driver IC and other modules. At the same time, it is controlled by the first Bluetooth module 102 to perform the power-on or power-off operations of each module, so as to realize the power-on and power-off and low-power mode management of the whole machine.

[0060] Based on the above embodiments, this application discloses another embodiment of an electrical stimulation control system based on a dual-stimulation source architecture, wherein the wired interface 108 is a TYPE-C interface.

[0061] The wired interface 108 serves as an output channel in wired mode, used to transmit the first electrical stimulation signal generated by the first stimulation module 106 to the wired earphone. The wired interface 108 also serves as a charging input channel, providing charging input to the first power management module 103.

[0062] In other embodiments, the remote controller 01 further includes a first charging management module 107, which is used to receive external power input, provide constant current and constant voltage charging management for the built-in lithium battery of the remote controller 01, and has safety protection functions such as overcharge, over-discharge, overcurrent and over-temperature to ensure battery safety.

[0063] Based on the above embodiments, this application discloses another embodiment of an electrical stimulation control system based on a dual-stimulus source architecture, as detailed in the appendix. Figure 3 As shown, the ear stimulator 02 specifically includes a second Bluetooth module 202, a second stimulation electrode 207, a button module 203, and a second power management module 204.

[0064] The second Bluetooth module 202 is communicatively connected to the second stimulation module 205 via a second universal asynchronous transceiver (UART).

[0065] The second stimulation module 205 is used to receive the second electrical stimulation parameters sent by the second Bluetooth module 202 through the second universal asynchronous transceiver, and generate the second electrical stimulation signal.

[0066] The second stimulation electrode 207 is used to transmit the second electrical stimulation signal to the human ear.

[0067] The button module 203 provides local control signals to the second Bluetooth module 202.

[0068] The second power management module 204 provides regulated power to each module of the ear stimulator and is controlled by the second Bluetooth module 202 to perform power-on or power-off operations.

[0069] Specifically, the second Bluetooth module 202, as the core control and communication unit of the ear stimulator, establishes a communication connection with the second stimulation module 205 through a second universal asynchronous transceiver. The second Bluetooth module 202 establishes a wireless connection with the remote control to receive parameter commands, and also receives local control signals from the button module 203. It then sends operating parameters and start / stop commands to the second stimulation module 205 via UART, achieving unified scheduling in both online controlled and offline autonomous modes.

[0070] The second stimulation module 205 is used to receive the second electrical stimulation parameters, including frequency, duty cycle and intensity, sent by the second Bluetooth module 202 through the second universal asynchronous transceiver, and locally generate a second electrical stimulation signal that meets the index requirements based on the above parameters, and independently complete waveform generation and output drive.

[0071] The second stimulation electrode 207 is disposed at the contact point between the ear stimulator and the human body. It is electrically connected to the output end of the second stimulation module 205 and is used to directly transmit the electrical stimulation signal generated by the second stimulation module 205 to the human ear tissue, thereby realizing the final bioelectric coupling input of electrical stimulation therapy.

[0072] The button module 203 serves as the local control unit for the ear stimulator, providing physical buttons for users to perform operations such as power on / off, intensity adjustment, and mode switching, and sending corresponding local control signals to the second Bluetooth module 202. In offline mode, this module enables the ear stimulator to achieve full-function control without relying on a remote control, giving the device complete independent working capability.

[0073] The second power management module 204 is responsible for the power distribution and management of each module inside the ear stimulator. It is connected to the second lithium battery 201 and provides a stable regulated power supply for the second Bluetooth module 202, the second stimulation module 205 and the button module 203. It is also controlled by the second Bluetooth module 202 to perform the power-on or power-off operations of each module, and cooperates to realize the overall power-on and power-off and low-power mode management of the ear stimulator.

[0074] In some alternative embodiments, the ear stimulator further includes a second charging management module 206, used to receive external power input, provide constant current and constant voltage charging management for the ear stimulator's built-in lithium battery, and have safety protection functions such as overcharge, over-discharge, overcurrent, and over-temperature protection to ensure the power supply safety and battery life reliability of the ear stimulator during independent use cycles. Optionally, the ear stimulator is charged via a charging case.

[0075] This application provides another embodiment of an electrical stimulation control system based on a dual-stimulation source architecture. Based on any of the above-described embodiments, the remote controller and the ear stimulator are respectively provided with non-volatile storage units for synchronously storing the user's historical physiotherapy prescriptions, electrical stimulation parameters, and usage logs.

[0076] The electrical stimulation parameters include the frequency, intensity, and duty cycle of the electrical stimulation signal.

[0077] Specifically, the non-volatile storage unit is used to synchronously store key data such as the user's historical physiotherapy prescriptions, settings, parameters, and usage logs.

[0078] Optionally, when the system switches between wired and wireless modes, the device after switching automatically reads the latest parameter configuration synchronously written by the device before switching from its local storage unit and directly uses this configuration to continue outputting without requiring user reconfiguration. When the ear stimulator resumes its wireless connection with the remote control from offline mode, the ear stimulator sends back all usage logs and parameter change records stored during the offline phase to the remote control. The remote control then summarizes and synchronously updates the storage units of both devices, achieving a closed-loop data transmission throughout the entire process.

[0079] Based on the same concept, this application also discloses an electrical stimulation control method based on a dual-stimulus source architecture. The method is implemented based on the control system described in any of the above embodiments. Specifically, one embodiment of the electrical stimulation control method based on a dual-stimulus source architecture of this application includes: The remote control detects whether the wired headphones are connected to the wired interface.

[0080] When the wired headphones are detected to be connected, the remote control activates the first stimulation module to generate the first electrical stimulation signal and outputs it through the wired interface. At the same time, it sends a lockout command to the ear stimulator through the wireless communication link, causing the second stimulation module to enter a sleep standby state and synchronize the current electrical stimulation parameters in real time.

[0081] When the wired headphones are not connected, the remote control sends a start command to the ear stimulator through the wireless communication link. The ear stimulator receives and responds to the start command, and the second stimulation module locally generates the second electrical stimulation signal and outputs it through the second stimulation electrode. At the same time, the first stimulation module enters a sleep standby state and synchronizes the current electrical stimulation parameters in real time.

[0082] When the wireless communication link is interrupted, the ear stimulator automatically switches to offline mode after disconnecting from the remote control. Based on the historical parameters stored locally, it independently controls the second stimulation module to continuously generate the second electrical stimulation signal, and the intensity can be adjusted and the start / stop can be controlled by local buttons.

[0083] In some implementations, in wired access scenarios, after the user plugs the wired headphones into the remote control, the remote control powers on and triggers distributed scheduling logic, prioritizing the first stimulation module as the output. The remote control automatically reads the historical therapy formulas and intensity parameters from the ear stimulator's local storage unit and directly uses them as the default configuration for the current wired mode.

[0084] Optionally, the remote controller synchronously sends a safety interlock command via the wireless communication link, locking the software flag inside the ear stimulator to an output-disabled state. Simultaneously, the hardware interlock circuit inside the remote controller locks the output enable terminal of the second stimulation module based on the level signal of the wired interface. At any given time, only the remote controller has one valid output, and the ear stimulator only performs parameter backup and standby monitoring functions. Any parameter changes used in this wired connection are synchronized bidirectionally in real time to the local storage units of both the remote controller and the ear stimulator.

[0085] In other embodiments, in a wired-to-wireless connection scenario, when the remote controller detects that the wired headphones have been disconnected from the wired interface, it detects a wired link disconnection signal and triggers distributed scheduling to automatically switch the output entity. The remote controller shuts down the output channel of the first stimulation module and sends a wireless mode switching command and the latest physiotherapy parameters for the current wired mode to the ear stimulator via Bluetooth. After receiving the switching command, the ear stimulator automatically retrieves historical parameters synchronously written to the wired mode from its local storage unit, and the second stimulation module locally generates an electrical stimulation waveform, which is then output through its electrodes.

[0086] Optionally, the remote control locks the output permissions of the first stimulation module through a software flag, retaining only the functions of issuing commands and displaying data. The wired headphones are idle and do not participate in operation, while the ear stimulator records the wireless therapy log and intensity changes in real time and temporarily stores them in the local storage area.

[0087] In other implementations, in an offline autonomous scenario following an unexpected Bluetooth disconnection, when the ear stimulator detects an interruption in the Bluetooth communication link with the remote control or when the remote control is powered off, the ear stimulator triggers offline switching logic in distributed scheduling. The ear stimulator directly calls historically stored user habit parameters in its local non-volatile storage unit, enabling the second stimulation module to enter a purely offline independent working state. The user can perform local control of power on / off, intensity adjustment, and mode switching via the button module on the ear stimulator, without needing to connect to the remote control throughout the process.

[0088] Optionally, the first stimulation module of the remote control remains in a locked sleep state, and the ear stimulator exclusively has the output privileges. All usage records, parameter changes, and timestamp information during offline therapy are stored in the local storage unit of the ear stimulator, awaiting transmission after reconnection to the remote control.

[0089] Based on the above embodiments, this application discloses another embodiment of an electrical stimulation control method based on a dual-stimulation source architecture. The ear stimulator continuously monitors the wireless signal in offline mode. When a pairing request from the remote control is detected and the signal strength is higher than a preset threshold, the ear stimulator exits the offline mode and re-establishes the connection.

[0090] After the ear stimulator re-establishes a wireless connection with the remote controller, the ear stimulator sends back the usage log stored during the offline phase and the current changes in electrical stimulation parameters to the remote controller. The remote controller then merges the offline data with the local data and synchronously updates the ear stimulator's storage unit, completing bidirectional data synchronization.

[0091] Specifically, once the ear stimulator re-establishes a Bluetooth connection with the remote control, a data closed-loop collaboration mechanism is triggered. The ear stimulator automatically transmits all usage logs, custom parameter change records, and cumulative usage time data stored during the offline phase back to the remote control. After receiving and parsing the transmitted data, the remote control merges the offline data with its own stored online data and handles any conflicts, generating an updated full user profile. The remote control then synchronously writes the updated full parameters into the ear stimulator's local storage unit, completing the bidirectional synchronous update of the data stored by both devices. The system optimizes the recommended values ​​for subsequent physiotherapy parameters based on the merged full-cycle historical data and synchronously displays the recommended results on the remote control's display module and applies them to the next stimulation output.

[0092] This application provides another embodiment of an electrical stimulation control method based on a dual-stimulatory-source architecture. Based on any embodiment of the above system, the control method further includes: When the ear stimulator is in wireless operation, and the remote control detects the wired headphones being inserted, the remote control sends a switching command to the ear stimulator. In response to the switching command, the ear stimulator cuts off the output of the second stimulation module and sends the current electrical stimulation parameters to the remote control. The remote control then activates the first stimulation module to continue outputting based on the current electrical stimulation parameters.

[0093] Specifically, in a scenario where wireless operation is temporarily switched to wired mode, while the ear stimulator is in wireless mode and continuously outputting electrical stimulation signals, the remote control detects that a wired headset is plugged into its wired interface. The remote control immediately sends an emergency switch command to the ear stimulator via Bluetooth. Responding to the emergency switch command, the ear stimulator cuts off the output path of the second stimulation module within a preset safety response time and packages and sends the current operating parameters and cumulative output to the remote control. Upon receiving the operating parameters, the remote control activates the first stimulation module and continuously generates electrical stimulation signals according to the received parameters, outputting them to the wired headset through the wired interface. Throughout the entire switching process, the electrical stimulation output interruption time does not exceed a preset safety threshold, and no manual parameter reset by the user is required.

[0094] Through this application, the remote control, wired headphones, and ear stimulator rely on four collaborative mechanisms: distributed scheduling to determine the main output, state inheritance to ensure parameter continuity, dual interlocking to control output safety, and data closed-loop for iterative optimization. This enables data interoperability, output mutual exclusion, and seamless mode transition among the three devices, truly achieving controlled online connection, autonomous disconnection, and synchronized reconnection.

[0095] Based on the same technical concept, this application also discloses an electrical stimulation device based on a dual-stimulus source architecture. The electrical stimulation device includes the electrical stimulation control system based on the dual-stimulus source architecture described in any of the above embodiments, wherein the remote controller, ear stimulator, and wired headphones are attached with reference to the accompanying specification.

[0096] The electrical stimulation control system, method, and device based on a dual-stimulation source architecture of this application have the same technical concept, and the technical details of the embodiments of the three are mutually applicable. To reduce repetition, they will not be described again here.

In practical applications, the above functions can be assigned to different program modules as needed, that is, the internal structure of the device can be divided into different program units or modules to complete all or part of the functions described above.
