[0002] With the development of science and technology, skin care has become an indispensable part of modern people's daily life, and more and more high-tech beauty equipment has gradually entered the daily life of the public. As one of them, electronic mask instruments use LED light therapy technology and micro-current penetration technology to improve skin conditions, such as sterilization, anti-aging, hydration, brightening, soothing and repairing, etc., and are deeply loved by the public.

[0003] In order to achieve better skin care effects for all areas of the skin, most electronic mask control devices have two controllers, which are used to control different areas of the face (such as the left and right face) to achieve comprehensive skin care for the face. However, in order to achieve the same skin care effects in the areas that the two controllers are responsible for, the controllers need to run synchronously. If they cannot run synchronously, the effects of the corresponding control areas will be affected, resulting in a reduced user experience. Although the two controllers in most current electronic masks can also work synchronously, there is still a lack of synchronization in the operating status and time during use, resulting in problems such as inconsistent experience when using the left and right areas of the face.

DETAILED DESCRIPTION

[0018] The following describes the embodiments of the present invention by specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0019] The present invention provides a synchronous control method of a beauty instrument, and the specific steps thereof include: Using wireless communication technology to connect the master device and the slave device; pairing the master device with the slave device based on the device address and device ID; If the devices are paired successfully, a unique communication address and frequency will be randomly assigned to each pair of devices; The master device encrypts the transmitted data using a data frame and then transmits it to the slave device to obtain the corresponding data. The slave device adjusts the current operating status according to the received data.

[0020] Specifically, the present invention uses wireless communication technology to achieve wireless transmission of data between the master and slave devices. Among them, the wireless communication technology used is 2.4G communication to ensure efficient communication between the master and slave devices. Before the master and slave devices communicate data, they use the address of the corresponding device and the unique device ID scanned and identified for pairing. Once the paired device is found, the master device sends a randomly generated address and frequency to the slave device, and the slave device records the address and frequency that are set to be consistent with the master device, and sends a successful reception instruction. The master device uses a random number generator (RTC timestamp randomness) to generate an address and frequency to ensure the uniqueness of the address and frequency, and the addresses and frequencies of different pairs of devices do not interfere with each other. Among them, the random address range is: 0x0000000000-0xFFFFFFFFFF, the frequency range is: 2400MHZ-2525MHZ, a total of 0~125 channels, and the channel interval is 1MHZ.

[0021] Among them, 2.4G communication can achieve lower power consumption and can be applied to devices with energy-saving requirements. The signal coverage area is large and can be fully used for short-distance transmission. It has low cost and can achieve two-way transmission with a single chip compared to 433. In a system using a synchronous control method for a beauty instrument, a wireless communication module is used to achieve data communication between the master and slave devices. Figure 1As shown, the wireless communication module includes: a power supply and a controller, a 2.4G chip, an impedance matching circuit, and an onboard antenna connected in sequence. The power supply supplies power to the controller and the 2.4G chip. The controller communicates with the 2.4G chip to read the data sent and received by the 2.4G chip. Impedance matching is to achieve maximum power transmission so that the transmission between the load impedance and the internal impedance of the signal source does not reflect or reflects very little. The onboard antenna can realize the miniaturization of the antenna, and there is no need to buy another antenna, which is cheap.

[0022] In the present invention, the master and slave devices ensure the security of data by identifying encrypted data frames when performing data transmission. When the data frames are identified, a CRC check algorithm is used to detect errors in data transmission to ensure data integrity.

[0023] The data frame structure includes: frame header, address, command, data field, CRC check and frame tail. The frame header can be set to identify the data frame, the address to identify the control operation, the command is the control operation of the corresponding address, and the data segment is the data to be transmitted (such as time, mode, gear position, etc.). When it is recognized that the data frame is not in the set range, the currently received data frame is discarded. When it is recognized that the data frame is in the set range, the data frame is CRC checked to ensure data security. The process of data interaction between the master and slave devices is as follows: Figure 2 shown.

[0024] like Figure 3 As shown, in the present invention, the master and slave devices coordinate the operation of the devices through timestamps and synchronization signals to ensure that the operation time difference is controlled within 10 milliseconds. Among them, the master device regularly sends synchronization signals (the regular time is within the time range where the error is less than 10ms, such as 1s will produce a time error of 1ms, then the synchronization time is set to 1s), and all slave devices adjust their own operating status according to the received synchronization signal. Among them, the beauty instrument is equipped with a simple user interface, which can display the pairing and synchronization status of the master and slave devices, i.e., the corresponding control devices. Users can easily start the pairing and synchronization functions of the device by pressing buttons.

[0025] In complex environments, the communication frequency and power can be adjusted dynamically to deal with potential wireless interference. The benefit of dynamic adjustment is that when there is interference with the same frequency in the environment, communication can be switched to other frequencies to eliminate interference from other useless frequencies. When no communication is detected, power communication is increased to ensure communication quality.

[0026] The invention provides a synchronous control method for a beauty instrument, which is applied to a beauty instrument system, and the system includes: a wireless communication module, a microcontroller, and a beauty instrument function output module (such as EMS, radio frequency, heating module, etc.). The system is set in each beauty instrument. Among them, the wireless communication module uses a 2Mbps 2.4G solution for communication to ensure low latency and high-efficiency communication between devices.

[0027] In the present invention, the operation process of the beauty instrument system is as follows: Device initialization: The user turns on the two beauty instruments and performs a unique key operation to automatically enter the pairing mode. The indicator light flashes to show the pairing status of the device.

[0028] Pairing process: The master device searches for other devices by broadcasting fixed addresses and frequency pairings. Once a paired device is found, the master device sends a randomly generated address and frequency to the slave device. The slave device records the address and frequency that are set to the same as the master device and sends a successful reception command. The master device uses a random number generator (RTC timestamp randomness) to generate addresses and frequencies to ensure the uniqueness of the addresses and frequencies. After the address and frequency exchange is completed, the master device will remember these paired addresses and frequencies so that these parameters can be used for communication in future communications.

[0029] Encrypted Communications: Face devices communicate by encrypting data packets. The data packet structure includes: frame header, device address, command, data field, CRC check, and frame tail. CRC check is used to ensure the integrity of data transmission.

[0030] Synchronization mechanism: The master device sends a synchronization signal containing timestamp information. The slave device receives the synchronization signal and adjusts the local clock to match the time of the master device. The master device uses a high-precision timer to ensure that the running time difference between devices is controlled within 10 milliseconds.

[0031] Running status synchronization: The master device periodically sends status updates and control commands, and the slave device adjusts operating parameters based on the received commands, such as operating time (in milliseconds), current operating status (such as EMS / RF frequency, voltage, etc.), to ensure that the operating status of all devices remains consistent and provide a synchronized somatosensory experience.

[0032] User interface: Users start and stop the device with a simple button, and the interface displays the current pairing status and synchronization status.

[0033] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
