Description

Technical Field

[0001] This invention relates to the field of dental equipment control technology, and in particular to a processing method, apparatus and system for control based on multi-band fusion communication. Background Technology

[0002] Dental foot switches, as core control components of dental treatment equipment, are currently mainly divided into two types: wired and wireless. Specifically, wired switch control transmits the collected analog electrical signals directly to the dental chair's control board via shielded cables. The control board converts the analog signals into 0-10V voltage values ​​and then triggers an emergency stop command directly through hardwiring. Wireless switch control quantizes the pedal travel into a digital value of 0-255 and sends it to the dental control terminal via Bluetooth data packets. The dental control terminal parses the data and converts it into device control commands. Alternatively, it uses a "command-response" interaction mechanism, waiting for confirmation from the dental control terminal after each control command is sent; if no confirmation is received, the command is automatically retransmitted.

[0003] However, in practice, it has been found that wired switch control restricts the doctor's position, the cables are easy to trip over and difficult to clean. While wireless switch control solves the shortcomings of wired switch control, existing wireless switch control uses a single communication method, and the clinic environment is complex with many 2.4GHz signal sources such as WiFi, mobile phone Bluetooth, and wireless monitoring devices, which can easily cause channel congestion, resulting in delays or loss of foot pedal commands, i.e., poor anti-interference ability. In addition, dental treatment equipment and peripheral equipment contain a lot of metal parts, and the diffraction ability of a single high-frequency signal (such as 2.4GHz) is weak, which can easily be blocked by metal and create signal blind spots, i.e., insufficient penetration.

[0004] Therefore, it is particularly important to propose a new dental foot switch control method to improve communication anti-interference capability and enhance communication penetration, thereby improving the success rate, stability, accuracy and reliability of dental control data transmission, and ultimately improving the control accuracy, efficiency and safety of dental equipment. Summary of the Invention

[0005] This invention provides a processing method, device, and system for control based on multi-band fusion communication, which can improve communication anti-interference capability and enhance communication penetration, thereby improving the success rate, stability, accuracy, and reliability of dental control data transmission, and further improving the control accuracy, efficiency, and safety of dental equipment.

[0006] The first aspect of this invention discloses a processing method for control based on multi-band fusion communication, the method being applied to a dental control terminal, the method comprising: The dental control terminal monitors the dental control data transmitted from the dental transmitter in real time through each of the multiple communication channels, and obtains the data monitoring results. The dental control terminal communicates with the dental transmitter through all the communication channels. The dental control data matched by each communication channel is obtained by the dental transmitter modulating the dental control parameters using the modulation frequency matched by the communication channel. The modulation frequencies corresponding to all the communication channels are different. The dental control parameters are obtained by the dental transmitter monitoring the status of the dental foot switch. The dental control terminal performs channel parsing on the data monitoring results to obtain the channel parsing results; The dental control terminal determines the target dental control data for controlling the dental equipment based on the channel parsing results and the data monitoring results.

[0007] As an optional implementation, in a first aspect of the present invention, the dental control terminal determines target dental control data for controlling the dental device based on the channel parsing result and the data monitoring result, including: The dental control terminal determines, based on the channel parsing result, whether there is dental control data corresponding to a preset communication channel in the data monitoring result monitored at the current monitoring time. The preset communication channel is one of the communication channels, and the modulation frequency corresponding to the preset communication channel is greater than the modulation frequency corresponding to the communication channel with the smallest modulation frequency among all the communication channels. When it is determined that dental control data corresponding to the preset communication channel exists, the dental control terminal verifies the dental control data corresponding to the preset communication channel and obtains the data verification result of the preset communication channel. When the data verification result of the preset communication channel indicates that the dental control data corresponding to the preset communication channel has passed verification, the dental control terminal determines the dental control data corresponding to the preset communication channel as the target dental control data for controlling the dental equipment.

[0008] As an optional implementation, in a first aspect of the present invention, the method further includes: When it is determined that there is no dental control data corresponding to the preset communication channel, or when the data verification result of the preset communication channel is used to indicate that the dental control data corresponding to the preset communication channel has failed verification and the data monitoring result is used to indicate that dental control data of other communication channels are being monitored at the current time, the dental control terminal verifies the dental control data of other communication channels being monitored at the current time to obtain the data verification result of the other communication channels. When the data verification result of the other communication channel indicates that the dental control data corresponding to the other communication channel has passed the verification, the dental control terminal determines the dental control data corresponding to the other communication channel as the target dental control data for controlling the dental equipment.

When it is determined that other dental control data exists, the dental control terminal deletes the other dental control data.

[0010] As an optional implementation, in a first aspect of the present invention, the dental control terminal verifies the dental control data corresponding to the preset communication channel to obtain the data verification result of the preset communication channel, including: The dental control terminal parses the dental control data corresponding to the preset communication channel to obtain the target verification parameter of the dental control data, and determines whether the target verification parameter matches the signal verification parameter in the dental control data corresponding to the preset communication channel. When it is determined that the two match, the dental control terminal determines whether the time stamp of the dental control data corresponding to the preset communication channel is used to indicate that the time step of the dental control data is more than the time step of the dental control data used to control the dental device by a preset time step. When it is determined that the time step of the time identifier used to indicate the dental control data is more than a preset time step than the time step of the previous dental control data used to control the dental device, the dental control terminal determines the data verification result of the preset communication channel to indicate that the dental control data corresponding to the preset communication channel has passed the verification.

The dental transmitter modulates the dental control parameters into dental control data that matches the communication channel through the modulation frequency corresponding to each of the multiple communication channels; wherein the modulation frequency corresponding to each communication channel is different. The dental transmitter transmits its corresponding dental control data to the dental control terminal through each of the communication channels, so that the dental control terminal can listen to the dental control data through each of the communication channels.

[0012] As an optional implementation, in a second aspect of the invention, the method further includes: During the transmission of dental control data, the dental transmitter monitors the link status of all communication channels and obtains the link status monitoring results. When the link status monitoring result indicates that no feedback response is received from the dental control terminal after sending heartbeat packets to the dental control terminal for a preset number of consecutive times, the dental transmitter determines that data loss has occurred in all the communication channels; The dental transmitter caches the dental control data corresponding to each communication channel and sorts the cached dental control data corresponding to each communication channel according to a preset priority. The dental transmitter performs an adjustment operation on the communication parameters of each of the communication channels and performs a retransmission operation on the dental control data corresponding to each of the sorted communication channels.

When the data verification result of the other communication channel indicates that the dental control data corresponding to the other communication channel has passed the verification, the dental control data corresponding to the other communication channel is determined as the target dental control data for controlling the dental equipment.

The deletion module is used to delete the other dental control data when it is determined that the other dental control data exists.

[0017] As an optional implementation, in a third aspect of the present invention, the specific method by which the first determining module verifies the dental control data corresponding to the preset communication channel to obtain the data verification result of the preset communication channel includes: The dental control data corresponding to the preset communication channel is parsed to obtain the target verification parameter of the dental control data, and it is determined whether the target verification parameter matches the signal verification parameter in the dental control data corresponding to the preset communication channel. When it is determined that the two match, it is determined whether the time stamp of the dental control data corresponding to the preset communication channel is used to indicate that the time step of the dental control data is more than the time step of the dental control data used to control the dental device by a preset time step. When it is determined that the time step of the time identifier used to indicate the dental control data is more than a preset time step than the time step of the previous dental control data used to control the dental device, the data verification result of the preset communication channel is determined to indicate that the dental control data corresponding to the preset communication channel has passed the verification.

[0018] A fourth aspect of the present invention discloses another processing device for control based on multi-band fusion communication, the device being applied to a dental transmitter, the device comprising: The generation module is used to generate dental control parameters that match the acquired dental control signals based on the type of the dental control signals.

[0021] The sixth aspect of the present invention discloses a dental control system, which includes a dental transmitter and a dental control terminal.

[0028] This invention discloses a processing method, apparatus, and system for control based on multi-band fusion communication. It converts acquired dental control parameters into dental control data in different frequency bands, then monitors this data through corresponding communication channels, performs channel and data analysis on the monitoring results, and finally selects the appropriate communication channel for dental control data to control the dental treatment equipment. This multi-channel communication architecture achieves frequency domain complementarity, improves communication anti-interference capability and enhances communication penetration, thereby improving the success rate, stability, accuracy, and reliability of dental control data transmission, and ultimately enhancing the accuracy, efficiency, and safety of dental equipment control. Detailed descriptions follow.

[0029] To better understand the processing method, apparatus, and system for control based on multi-band fused communication described in this invention, a schematic diagram of its system architecture is first described. Optionally, the schematic diagram of the system architecture can be as follows: Figure 1 As shown, Figure 1 This is a schematic diagram of the system architecture corresponding to a processing method for control based on multi-band fusion communication disclosed in an embodiment of the present invention. Figure 1 As shown in the diagram, the system architecture includes a dental transmitter (corresponding to a wireless foot pedal), a dental control unit (corresponding to the dental chair unit), and a communication channel (also known as a spatial channel) between the two. The dental transmitter comprises a switch acquisition unit, a core processing unit, and a multi-mode wireless communication module. The switch acquisition unit includes a push-button switch and a foot switch. The push-button switch is used to switch functions, such as water spray and air spray, while the foot switch controls the range of each function, such as the air spray volume. The core processing unit includes an MCU and a communication detection unit. The communication detection unit acquires dental control signals, and the MCU analyzes the acquired signals to obtain the corresponding dental control parameters. The multi-mode wireless communication module includes multiple communication modules, such as BLE and LoRa modules, used to modulate the dental control parameters into dental control data based on the corresponding modulation frequency. Furthermore, the dental transmitter also includes a power management unit (such as a lithium battery and battery IC) to power the transmitter. Each multi-mode wireless communication module has a unique corresponding communication channel for transmitting the dental control data to the dental control unit. The dental control unit includes a main unit processing unit and a multi-mode wireless communication module. The multi-mode wireless communication module, such as a BLE module or a LoRa module, is used for monitoring dental control data. The main unit processing unit parses and analyzes the monitored dental control data to obtain the final target dental control data used to control the dental equipment. It should be noted that... Figure 1 The system architecture diagram shown is for illustrative purposes only and does not represent that the system architecture of this invention is limited to this specific architecture. Figure 1 As shown, other system architectures that can achieve the same function are also within the scope of protection of this invention.

[0030] Example 1 Please see Figure 2 , Figure 2 This is a flowchart illustrating a control method based on multi-band fusion communication disclosed in an embodiment of the present invention. Figure 2 The described method can be applied to dental medical scenarios requiring dental control data transmission, such as molar reduction and cutting scenarios. Figure 2 As shown, the method may include the following operations: 101. The dental control terminal monitors the dental control data transmitted from the dental transmitter in real time through each of the multiple communication channels that is matched with that communication channel, and obtains the data monitoring results.

[0031] In this embodiment of the invention, the dental control terminal communicates with the dental transmitter through all communication channels. Dental control data matched to each communication channel is obtained by the dental transmitter modulating the dental control parameters using the modulation frequency matched to that communication channel. The modulation frequencies corresponding to all communication channels are different. The dental control parameters are obtained by the dental transmitter monitoring the state of the dental foot switch. Specifically, the dental transmitter monitors the state of the dental foot switch to obtain the dental control parameters. The dental wireless foot switch is equipped with a linear sensor (such as a Hall sensor) and a microswitch. The dental transmitter acquires the analog signal (e.g., 0-3.3V, i.e., the pedal depth control signal) from the linear sensor at a first preset frequency (e.g., 1kHz), and the digital signal (e.g., high / low level, i.e., the function control signal) from the microswitch at a second preset frequency (e.g., 200Hz). The acquired analog and digital signals are stored in their respective buffers. For the pedal depth control signal, the dental transmitter, based on a preset data filtering window (e.g., 10 sampling points, corresponding to a 10ms time window, balancing real-time performance and stability), acquires multiple pedal depth control signals from the pedal depth control signal buffer and calculates the average of all pedal depth control signals to obtain the dental pedal depth control signal mean. Optionally, after acquiring a new pedal depth control signal, a preset number (e.g., 1 or 2) of the pedal depth control signals stored first in the corresponding buffer can be deleted from the buffer to allow the new data to be stored and reduce data storage congestion. Further optionally, if the difference between a single sampled pedal depth control signal and the average of the previous dental pedal depth control signal exceeds a preset threshold (e.g., 0.2V), it is determined to be an abnormal change. In this case, the average of the previous dental pedal depth control signal is directly used to reduce signal jumps caused by mechanical vibration, thereby improving the control stability of the dental treatment equipment. For the function control signal, the dental transmitter starts delaying for a preset time (e.g., 20ms) after detecting a change in the microswitch level (i.e., a change in the function control signal from high to low or low to high) to accommodate the rebound time of the foot pedal mechanical action. At the end of the preset time, the foot pedal function switch level is acquired again to obtain the target foot pedal function switch level. This target level is then compared with the level before the delay to obtain a comparison result. If the comparison result indicates that the two are the same, the target foot pedal function switch level is determined to be the required function control signal; otherwise, it is a jitter signal, and no function switching is required, maintaining the original function state. The dental transmitter synchronously sends the filtered linear pedal depth control signal (now converted to 0~100% pedal travel value) and the de-jittered function control signal (press / release) to the data encapsulation module.The dental transmitter reads the filtered linear pedal depth control signal and the debounced function control signal from the buffer, generates the corresponding function code, such as 0x03 for high-speed rotation + water spray. It then splices the device ID, function code, linear pedal depth control signal and time identifier according to the preset frame structure splicing method (such as device ID + function code + data + time identifier (such as serial number)). It then calculates the signal verification parameters of the spliced ​​frame structure, adds a fixed length (such as 2) frame header and frame tail before and after the data segment to form a communication frame of a preset number of bytes (such as 14 bytes), and converts the communication frame into a binary stream to obtain the dental control data.

[0032] In this embodiment of the invention, the dental transmitter has multiple communication modules, each with its own communication channel. After obtaining the dental control parameters, the dental transmitter simultaneously drives the corresponding communication module through its communication interface. This allows the communication module to modulate the dental control parameters into dental control data that matches its corresponding modulation frequency. Each communication module has a different modulation frequency. The corresponding dental control data is then transmitted to the dental control terminal through its respective communication channel, enabling the dental control terminal to monitor the dental control data through each communication channel.

[0033] Taking the BLE5.2 module and LoRa module as examples, for the BLE5.2 module, the dental transmitter sends configuration commands to the BLE5.2 module via the UART interface to set parameters for module initialization, such as operating frequency band: 2.402~2.480GHz (BLE standard frequency band); modulation method: GFSK (Gaussian Frequency Shift Keying), frequency offset ±250kHz; baud rate: 1Mbps, encoding method NRZ-I; transmit power: 0dBm (balancing power consumption and short-range communication stability). After the module initialization is completed, the constructed 14-byte dental control parameters are sent to the BLE5.2 module's transmit buffer via the UART interface, and a start transmit command (such as 0x01) is sent. The BLE5.2 module modulates the binary frame data into a GFSK high-frequency signal and radiates it out through the built-in antenna. The BLE5.2 module sends a modulation completion signal (0x00) to the dental transmitter, waiting for the next data input. In this way, the continuously changing pedal travel data can be transmitted quickly through the high-bandwidth communication channel. For the LoRa module, the dental transmitter sends configuration commands to the LoRa module via the SPI interface to set parameters for module initialization. Operating frequency: 433MHz (unlicensed band, suitable for penetration requirements in medical scenarios); Modulation method: CSS (chirped spread spectrum), spreading factor SF=12, bandwidth 125kHz; Encoding method: convolutional coding (code rate 4 / 5), forward error correction (FEC) enabled; Transmit power: 17dBm (enhanced penetration, covering scenarios with metal obstructions in dental clinics). After module initialization, and simultaneous data loading synchronization with the BLE5.2 module, the dental transmitter writes the same 14 bytes of dental control parameters to the LoRa module via the SPI interface. The LoRa module transmits a buffer to ensure complete consistency between the two data streams. The dental transmitter simultaneously sends trigger signals (active high) to both the BLE5.2 and LoRa modules via GPIO pins, ensuring concurrent transmission of the two modulated signals. The LoRa module modulates the frame data into a CSS low-frequency spread spectrum signal, which is then radiated out through an external antenna. Upon completion, it sends a completion signal back to the dental transmitter. This communication channel, with its strong diffraction and anti-interference characteristics, modulates the same data frames as the BLE5.2 module into low-frequency wireless signals for transmission, ensuring data delivery even when obstructed by metal or congested in the 2.4G channel. This improves the success rate and stability of dental control data transmission.

[0034] In this embodiment of the invention, the dental control terminal has the same number of receiving modules with the same modulation parameters as the dental transmitter. Again, using BLE5.2 and LoRa modules as examples, the dental control terminal initializes the BLE5.2 and LoRa modules by setting parameters identical to those of the BLE5.2 module in the dental transmitter (2.4GHz frequency band, GFSK demodulation, 1Mbps baud rate), enabling the receive interrupt function (i.e., triggering an interrupt when a valid signal is detected), and continuously monitoring the 2.4GHz frequency band. Simultaneously, it sets parameters identical to those of the LoRa module in the dental transmitter (433MHz frequency band, CSS demodulation, SF=12), enables forward error correction decoding and receive interrupt functions, and continuously monitors the 433MHz frequency band. Both communication modules are in a low-power receiving state.

[0035] 102. The dental control terminal performs channel analysis on the data monitoring results to obtain the channel analysis results.

[0036] In this embodiment of the invention, the channel resolution result is used to indicate the type of communication channel being monitored, or which communication channel is monitoring the corresponding frequency band. Specifically, different communication modules of the dental control terminal, when detecting a wireless signal matching their own modulation parameters, initiate a demodulation process. For example, the BLE5.2 receiving module performs carrier recovery and bit synchronization on the dental control data of the GFSK signal, demodulates it into binary frame data, and sends it to the dental control terminal through the UART interface; the LoRa receiving module performs spread spectrum despreading and FEC decoding on the dental control data of the CSS signal, demodulates it into binary frame data, and sends it to the dental control terminal through the SPI interface. After demodulation, the receiving module sends an interrupt signal to the dental control terminal through the GPIO pin (where the interrupt pin INT1 corresponds to the BLE5.2 receiving module, and INT2 corresponds to the LoRa receiving module), requesting the dental control terminal to read the corresponding dental control data. The dental control terminal responds to the interrupt, reads the demodulated dental control data from the BLE5.2 receiving module and the LoRa receiving module respectively, stores it in their respective independent buffers, and marks the reception timestamp (accurate to 1ms).

[0037] 103. Based on the channel analysis results and data monitoring results, the dental control terminal determines the target dental control data for controlling the dental equipment.

[0038] In this embodiment of the invention, after obtaining the target dental control data, the target dental control data is parsed to obtain the corresponding control commands. The main control board drives the motor to operate at a specified speed and torque according to the commands, controlling functions such as water and air supply, thereby achieving precise control of the dental equipment. The function commands and function range commands in the control commands can be separate or combined. For example, in a combined case, the first 50% of the pedal stroke only involves air jetting, while beyond 50%, water jetting and rotation occur simultaneously. This combination logic (such as pedal + side button) reduces the risk of the dentist accidentally triggering drill rotation when moving the pedal, improving the control safety of the dental equipment.

[0039] It is evident that implementation Figure 2 The described method converts the collected dental control parameters into dental control data in different frequency bands, then monitors the dental control data in different frequency bands through corresponding communication channels, and performs channel and data analysis on the data monitoring results. Finally, based on the analysis results, it selects the dental control data corresponding to the appropriate communication channel for controlling dental treatment equipment. In other words, through a multi-communication channel communication architecture, frequency domain complementarity is achieved, which improves the anti-interference capability and enhances the communication penetration, thereby improving the transmission success rate, stability, accuracy, and reliability of dental control data, and reducing the packet loss rate of dental control data. This is conducive to improving the control accuracy, efficiency, and safety of dental equipment. For example, in high-risk operations such as tooth grinding and cutting, it reduces communication interruptions, enables timely cessation, and reduces medical accidents.

[0040] In this embodiment of the invention, optionally, the dental control terminal determines the target dental control data for controlling the dental device based on the channel parsing results and data monitoring results, including: Based on the channel parsing results, the dental control terminal determines whether there is dental control data corresponding to the preset communication channel in the data listening results at the current listening time. The preset communication channel is one of the communication channels, and the modulation frequency corresponding to the preset communication channel is greater than the modulation frequency corresponding to the communication channel with the smallest modulation frequency among all communication channels. When it is determined that dental control data corresponding to a preset communication channel exists, the dental control terminal verifies the dental control data corresponding to the preset communication channel and obtains the data verification result of the preset communication channel. When the data verification result of the preset communication channel indicates that the dental control data corresponding to the preset communication channel has passed the verification, the dental control terminal determines the dental control data corresponding to the preset communication channel as the target dental control data for controlling the dental equipment.

[0041] In this embodiment of the invention, optionally, the number of all communication channels is greater than or equal to 2. When it is equal to 2, the modulation frequency corresponding to the preset communication channel is greater than the modulation frequency corresponding to the other communication channel, i.e., the operating frequency band of the communication module. For example, if there are two communication modules, namely the BLE 5.2 module and the LoRa module, then the communication channel corresponding to the BLE 5.2 module is the preset communication channel. When it is greater than 2, the division of each communication channel will be more detailed. Taking 3 communication channels as an example, the first communication channel, the second communication channel, and the third communication channel are respectively the communication channel corresponding to the BLE 5.2 module, the communication channel corresponding to the LoRa module, and the communication channel corresponding to the WiFi 6 module. Among them, the communication channel corresponding to the BLE 5.2 module is the core link, transmitting linear pedal travel and conventional function control commands (such as water spray and air jet), and has the highest priority; the communication channel corresponding to the LoRa module is the backup link, transmitting critical commands such as emergency stop and mode switching, and has the second highest priority; the communication channel corresponding to the WiFi 6 module is the redundant backup link, transmitting all commands, i.e., the control commands of the aforementioned two communication channels, adapting to unobstructed and multi-device scenarios, and has the lowest priority. At this point, the dental control terminal calculates the RSSI value and packet loss rate for each communication channel in real time, and obtains a channel score value according to a preset algorithm. The stronger the signal and the lower the packet loss rate, the higher the score. Based on all channel scores, the matching communication channel with the highest score is selected, and the dental control data corresponding to the matching communication channel is verified. If the verification passes, the dental control data corresponding to the matching communication channel is determined as the target dental control data for controlling the dental equipment. If the verification fails, the dental control data corresponding to the highest priority communication channel is selected from the remaining communication channels based on priority and verified. If the verification passes, it is used as the target dental control data for controlling the dental equipment. If all channel scores are equal, the dental control data corresponding to the highest priority communication channel is selected from all communication channels based on priority and verified. If the verification passes, it is used as the target dental control data for controlling the dental equipment. This approach, by expanding multiple communication channels to transmit dental control data in a more detailed manner, achieves complementary transmission of dental control data in different situations. For example, 5GHz WiFi 6 can avoid WiFi interference in the 2.4GHz band, forming a triple complement with LoRa's penetration and BLE's low power consumption. This further reduces the packet loss rate of dental control data, increases the probability of successful transmission, and consequently improves the smoothness and accuracy of dental equipment control. It also expands the applicable scenarios, such as adapting to the complex environment of large dental clinics (multiple treatment rooms and multiple devices).

[0042] It should be noted that for details regarding dental control data verification, please refer to the verification instructions for the dental control data corresponding to the preset communication channels below, which will not be repeated here. Furthermore, if all communication channels fail to transmit dental control data, it indicates that dental control data packet loss has occurred, signifying an anomaly. For a detailed description of this anomaly, please refer to the anomaly process description below.

[0043] As can be seen, when the embodiment of the present invention determines that there is a communication channel with the highest modulation frequency among all the communication channels monitored, the dental control data corresponding to the communication channel is verified, and when the verification is successful, the dental control data is directly used to control the dental equipment. That is, under normal conditions, the high-speed characteristics (high bandwidth characteristics) of the communication channel corresponding to the high modulation frequency are used to stably and efficiently transmit dental control data, that is, to quickly transmit continuously changing pedal travel data, so as to improve the control accuracy and reliability of the dental equipment.

[0044] In a further optional embodiment of the present invention, the dental control terminal verifies the dental control data corresponding to the preset communication channel to obtain the data verification result of the preset communication channel, including: The dental control terminal parses the dental control data corresponding to the preset communication channel, obtains the target verification parameters of the dental control data, and determines whether the target verification parameters match the signal verification parameters in the dental control data corresponding to the preset communication channel. When the two are determined to match, the dental control terminal determines whether the time stamp of the dental control data corresponding to the preset communication channel is used to indicate that the time step of the dental control data is more than the preset time step of the dental control data used to control the dental equipment. When it is determined that the time step of the dental control data is more than the time step of the previous dental control data used to control the dental equipment by a preset time step (e.g., 1), the dental control terminal determines the data verification result of the preset communication channel to indicate that the dental control data corresponding to the preset communication channel has passed the verification.

[0045] In this embodiment of the invention, each transmitted dental control data has a unique corresponding time identifier. Optionally, the time identifier can be any marker that can identify time, such as a serial number. Furthermore, after the dental control data is executed by the dental device, the dental control data itself or the time identifier within the dental control data is recorded separately for time step verification of the next dental control data.

[0046] In this embodiment of the invention, optionally, when it is determined that the two do not match, such as the target verification parameter and the signal verification parameter being different, it indicates that the current dental control data is incomplete, that is, the data verification result of the preset communication channel is used to indicate that the dental control data corresponding to the preset communication channel fails verification. Alternatively, when it is determined that the time step of the time identifier used to indicate the dental control data is less than or greater than the preset time step compared to the time step of the dental control data used to control the dental device last time, such as the time step of the current dental control data being Seq ID=156 being greater than the time step of the dental control data used to control the dental device last_Seq_ID=155, it indicates that the data verification result of the preset communication channel is used to indicate that the dental control data corresponding to the preset communication channel fails verification.

[0047] As can be seen, by implementing the embodiments of the present invention, the accuracy and reliability of dental control data verification are improved by sequentially verifying the integrity and time step of the dental control data corresponding to the selected communication channels. Furthermore, when either the integrity or time step condition is not met, the system can quickly switch to the dental control data parsing of another communication channel, ensuring that the dental device can successfully obtain the corresponding dental control data. This increases the probability of using accurate and reliable dental control data, thereby improving the control accuracy and stability of the dental device.

[0048] In an optional embodiment, the method may further include the following steps: When it is determined that there is no dental control data corresponding to the preset communication channel, or when the data verification result of the preset communication channel is used to indicate that the dental control data corresponding to the preset communication channel has failed verification and the data monitoring result is used to indicate that dental control data of other communication channels are being monitored at the same time, the dental control terminal verifies the dental control data of other communication channels being monitored at the same time and obtains the data verification result of other communication channels. When the data verification results of other communication channels are used to indicate that the dental control data corresponding to other communication channels has passed verification, the dental control terminal determines the dental control data corresponding to other communication channels as the target dental control data for controlling the dental equipment.

[0049] In this embodiment of the invention, the process of verifying dental control data of other communication channels is detailed in the above-mentioned description and will not be repeated here.

[0050] In this embodiment of the invention, the modulation frequency corresponding to other communication channels is lower than the modulation frequency corresponding to the preset communication channel. Optionally, if the data monitoring result indicates that dental control data from other communication channels is not simultaneously monitored at the current time, then it indicates that dental control data packet loss has occurred, which indicates an anomaly. In this case, the following operations are performed: During the transmission of dental control data, the dental transmitter monitors the link status of all communication channels and obtains the link status monitoring results. When the link status monitoring results indicate that no feedback response is received from the dental control terminal after sending heartbeat packets to the dental control terminal for a preset number of consecutive times, the dental transmitter determines that data loss has occurred in all communication channels. The dental transmitter caches the dental control data corresponding to each communication channel and sorts the cached dental control data corresponding to each communication channel according to a preset priority. The dental transmitter performs adjustment operations on the communication parameters of each communication channel and performs a retransmission operation on the dental control data corresponding to each sorted communication channel. For example, the dental transmitter uses a heartbeat mechanism, such as sending an empty data frame every 100ms, to monitor the link status of all communication channels. If it fails to receive an ACK response from the dental control end for three consecutive times (e.g., an ACK frame is 1 byte, 0x0A indicates successful reception), it determines that packet loss has occurred on all communication channels. The dental transmitter automatically adjusts the LoRa module parameters (e.g., increasing the spreading factor SF from 12 to 14 to enhance anti-interference capability) and the BLE5.2 module transmit power (e.g., increasing from 0dBm to 4dBm), while reducing the transmission rate of dental control data (e.g., reducing from 1kHz to 500Hz) to improve the success rate of dental control data transmission. The dental transmitter buffers the five most recent unacknowledged control commands, sorts them according to the priority of emergency stop > mode switching > parameter adjustment, and retransmits them sequentially after parameter adjustment until an ACK is received or the maximum number of retransmissions is reached, such as 10 times. Furthermore, if the dental control data transmission still fails after the maximum number of retransmissions, the dental transmitter or control unit triggers an audible and visual alarm (e.g., flashing LED light in the foot switch + buzzer sound), and simultaneously sends an emergency stop command to the dental equipment to reduce medical risks. By sending heartbeat packets at intervals, all communication channel packet loss can be accurately identified in a short time, reducing the risk of dental equipment malfunction due to communication delays. Additionally, by adjusting a combination of parameters—increasing the spreading factor of low-speed communication channels, enhancing the transmission power of high-speed communication channels, and reducing the transmission rate—the transmission of dental control data can be effectively penetrated through obstructions such as metal X-ray machines and lead shielding walls, significantly improving the success rate of dental control data transmission in complex scenarios. Furthermore, through tiered security, control commands are prioritized for retransmission and buffering, ensuring high-risk operations are executed first. And when multiple retransmission failures occur, i.e., prolonged packet loss, an early warning is issued, forming a closed-loop protection system from fault detection to risk prevention. This significantly reduces the probability of communication-related medical accidents during dental operations and improves the control safety and reliability of dental equipment.

[0051] As can be seen, implementing this optional embodiment allows for the verification of dental control data transmitted from other low-speed communication channels when the high-speed communication channel fails to transmit dental control data, or when packet loss occurs, or when data verification fails even after transmission. Upon successful verification, this dental control data is used to control the dental equipment. This utilizes the diffraction and anti-interference capabilities of the low-speed communication channel to compensate for the signal blind spots of the high-speed communication channel in metal-dense environments, immediately compensating for the data loss and ensuring data delivery even when metal obstructions or high-speed communication channel congestion. Furthermore, the use of multi-channel redundant transmission ensures successful transmission of dental control data even if one channel is completely interfered with, significantly reducing the packet loss rate and guaranteeing the normal operation of the dental equipment. In emergency situations, the multi-communication channel mechanism guarantees the delivery of dental control data while also considering battery life.

[0052] In another optional embodiment, each communication channel transmits dental control data with a unique timestamp each time; after the dental control terminal determines the target dental control data for controlling the dental device based on the channel parsing results and data monitoring results, the method may further include the following steps: Based on the data monitoring results, the dental control terminal determines whether there is other dental control data with the same timestamp as the dental control data corresponding to the target communication channel. The target communication channel is either a preset communication channel or another communication channel. When other dental control data is detected, the dental control terminal deletes the other dental control data.

[0053] In this optional embodiment, each dental control parameter has a unique corresponding time identifier. When the dental control parameter is modulated into corresponding dental control data by the communication module corresponding to each communication channel, the dental control data corresponding to each communication channel will carry the same unique time identifier. In this way, the dental control terminal can seamlessly receive dental control data, improving the smoothness and efficiency of dental equipment operation, so that the staff will not feel any interruption or delay. Specifically, when the target communication channel is a preset communication channel, other dental control data with the same time identifier as the dental control data corresponding to the target communication channel are dental control data of other communication channels besides the preset communication channel; when the target communication channel is another communication channel, other dental control data with the same time identifier as the dental control data corresponding to the target communication channel are dental control data of the preset communication channel or other communication channels (different from other communication channels). In this case, since the dental equipment has already executed the dental control data with that time identifier, when dental control data with the same time identifier is received, it indicates that the dental control data is redundant data and is deleted. For details on the time identifier, please refer to the above description, which will not be repeated here.

[0054] In this optional embodiment, if it is determined that no other dental control data exists, step 101 is continued.

[0055] As can be seen, implementing this optional embodiment, by setting the same and unique timestamp for dental control data synchronously transmitted through each communication channel, accurately identifies duplicate dental control data, thereby improving the accuracy and efficiency of data redundancy deduplication. Furthermore, by retaining and executing only the first received valid dental control data and deleting other redundant data with the same timestamp, it significantly reduces the risk of erroneous operations such as secondary acceleration and repeated start-stop of dental equipment, thus improving the control safety of dental equipment. Additionally, data redundancy deduplication reduces the data analysis load on the dental control end, greatly improving the control response speed of dental equipment.

[0056] Example 2 Please see Figure 3 , Figure 3 This is a flowchart illustrating another processing method for control based on multi-band fusion communication disclosed in an embodiment of the present invention. Figure 3 The described method can be applied to dental medical scenarios requiring dental control data transmission, such as molar reduction and cutting scenarios. Figure 3 As shown, the method may include the following operations: 201. The dental transmitter generates dental control parameters that match the type of dental control signal acquired. The types of dental control signals include pedal depth control signal type and / or function control signal type.

[0057] 202. The dental transmitter modulates the dental control parameters into dental control data that matches the communication channel through the modulation frequency corresponding to each of the multiple communication channels; wherein, the modulation frequency corresponding to each communication channel is different.

[0058] 203. The dental transmitter transmits its corresponding dental control data to the dental control terminal through each communication channel, so that the dental control terminal can listen to the dental control data through each communication channel.

[0059] It is evident that implementation Figure 3 The described method generates corresponding dental control parameters from the acquired dental control signals. Then, it modulates these parameters using the modulation frequency (operating frequency band) of the communication module corresponding to each communication channel, obtaining dental control data that matches the frequency domain of the corresponding communication channel. This modulated dental control data is then transmitted to the dental control terminal via the corresponding communication channel. The dental control terminal listens to the corresponding dental control data through each communication channel and controls the dental equipment based on the data listening results. This multi-communication channel architecture modulates and transmits dental control parameters, achieving frequency domain complementarity, improving communication anti-interference capabilities and enhancing communication penetration. This improves the success rate, stability, accuracy, and reliability of dental control data transmission, reduces the packet loss rate, and ultimately enhances the accuracy, efficiency, and smoothness of dental equipment control.

[0060] In an optional embodiment, the method may further include the following steps: During the transmission of dental control data, the dental transmitter monitors the link status of all communication channels and obtains the link status monitoring results. When the link status monitoring result indicates that no feedback response has been received from the dental control terminal after sending heartbeat packets to the dental control terminal for a preset number of consecutive times, the dental transmitter determines that data loss has occurred in all communication channels. The dental transmitter caches the dental control data corresponding to each communication channel and sorts the cached dental control data corresponding to each communication channel according to a preset priority. The dental transmitter performs adjustment operations on the communication parameters of each communication channel and retransmits the dental control data corresponding to each sorted communication channel.

[0061] As can be seen, this optional embodiment can accurately identify all communication channel packet loss in a short time by sending heartbeat packets at intervals, reducing the risk of dental equipment malfunction due to communication delays; and by adjusting the combined parameters of increasing the spreading factor of the low-speed communication channel, increasing the transmission power of the high-speed communication channel, and reducing the transmission rate, it can effectively penetrate obstructions such as metal dental X-ray machines and lead protective walls, greatly improving the transmission success rate of dental control data in complex scenarios; and through hierarchical security, it prioritizes and retransmits control commands to ensure that high-risk operations are executed first, and provides early warning after multiple failed retransmissions, i.e., when packet loss occurs for a long time, forming a closed-loop protection from fault detection to risk prevention, greatly reducing the probability of communication-related medical accidents in dental operations and improving the control safety and reliability of dental equipment.

[0062] It should be noted that for a detailed description of other related content in Embodiment 2, please refer to the relevant detailed description in Embodiment 1 above, and it will not be repeated here.

[0063] Example 3 Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of a processing device for control based on multi-band fusion communication disclosed in an embodiment of the present invention. Figure 4 The described device can be applied in dental medical scenarios requiring dental control data transmission, such as tooth grinding and cutting. Figure 4 As shown, the device may include: The monitoring module 301 is used to monitor the dental control data transmitted from the dental transmitter in real time through each of the multiple communication channels that matches the communication channel, and obtain the data monitoring results. The dental control terminal communicates with the dental transmitter through all communication channels. The dental control data matched by each communication channel is obtained by the dental transmitter using the modulation frequency matched by the communication channel to modulate the dental control parameters. The modulation frequencies corresponding to all communication channels are different. The dental control parameters are obtained by the dental transmitter monitoring the status of the dental foot switch. The parsing module 302 is used to perform channel parsing on the data monitoring results to obtain the channel parsing results; The first determining module 303 is used to determine the target dental control data for controlling the dental equipment based on the channel parsing results and data monitoring results.

[0064] It is evident that implementation Figure 4The described device converts the collected dental control parameters into dental control data in different frequency bands, then listens to the dental control data in different frequency bands through corresponding communication channels, and performs channel and data analysis on the data listening results. Finally, based on the analysis results, it selects the dental control data corresponding to the appropriate communication channel for controlling the dental treatment equipment. That is, through the multi-communication channel communication architecture mode, frequency domain complementarity is achieved, which improves the communication anti-interference capability and enhances the communication penetration, thereby improving the transmission success rate, stability, accuracy and reliability of dental control data, and thus improving the control accuracy, efficiency and safety of dental equipment.

[0065] In this embodiment of the invention, optionally, the first determining module 303 determines the specific method for controlling the target dental control data for the dental device based on the channel parsing results and data monitoring results, including: Based on the channel parsing results, it is determined whether there is dental control data corresponding to the preset communication channel in the data listening results at the current listening time. The preset communication channel is one of the communication channels among all communication channels. The modulation frequency corresponding to the preset communication channel is greater than the modulation frequency corresponding to the communication channel with the smallest modulation frequency among all the communication channels. When it is determined that dental control data corresponding to a preset communication channel exists, the dental control data corresponding to the preset communication channel is verified to obtain the data verification result of the preset communication channel. When the data verification result of the preset communication channel indicates that the dental control data corresponding to the preset communication channel has passed the verification, the dental control data corresponding to the preset communication channel is determined as the target dental control data for controlling the dental equipment.

[0066] It is evident that implementation Figure 4 When the device determines that there is a communication channel with the highest modulation frequency among all the communication channels monitored, it verifies the dental control data corresponding to that communication channel. If the verification is successful, it directly uses the dental control data to control the dental equipment. That is, under normal conditions, it uses the high-speed characteristics (high bandwidth characteristics) of the communication channel corresponding to the high modulation frequency to transmit dental control data stably and efficiently, that is, to quickly transmit continuously changing pedal travel data, so as to improve the control accuracy and reliability of the dental equipment.

[0067] In this embodiment of the invention, optionally, the first determining module 303 determines the specific method of the target dental control data used to control the dental device based on the channel parsing result and the data monitoring result, and further includes: When it is determined that there is no dental control data corresponding to the preset communication channel, or when the data verification result of the preset communication channel is used to indicate that the dental control data corresponding to the preset communication channel has failed verification and the data monitoring result is used to indicate that dental control data of other communication channels are monitored at the same time, the dental control data of other communication channels monitored at the same time are verified to obtain the data verification result of other communication channels. When the data verification results of other communication channels are used to indicate that the dental control data corresponding to other communication channels has passed verification, the dental control data corresponding to other communication channels is determined as the target dental control data for controlling the dental equipment.

[0068] It is evident that implementation Figure 4 The described device verifies dental control data transmitted from other low-speed communication channels when the high-speed communication channel fails to transmit dental control data, or when packet loss occurs, or when data verification fails even after transmission. Upon successful verification, this dental control data is used to control the dental equipment. This utilizes the diffraction and anti-interference capabilities of the low-speed communication channel to compensate for the signal blind spots of the high-speed communication channel in metal-dense environments, immediately compensating for the data loss and ensuring data delivery even when metal obstructions or high-speed communication channel congestion. Furthermore, the use of multi-channel redundant transmission ensures successful transmission of dental control data even if one channel is completely interfered with, significantly reducing packet loss and guaranteeing normal operation of the dental equipment. In emergency situations, the multi-communication channel mechanism guarantees the delivery of dental control data while also considering battery life.

[0069] In this embodiment of the invention, optionally, the first determining module 303 verifies the dental control data corresponding to the preset communication channel to obtain the data verification result of the preset communication channel, including the following specific methods: Parse the dental control data corresponding to the preset communication channel to obtain the target verification parameters of the dental control data, and determine whether the target verification parameters match the signal verification parameters in the dental control data corresponding to the preset communication channel. When the two are determined to match, it is determined whether the time stamp of the dental control data corresponding to the preset communication channel is used to indicate that the time step of the dental control data is more than the preset time step of the dental control data used to control the dental equipment. When it is determined that the time step of the time identifier used to represent the dental control data is more than the time step of the previous dental control data used to control the dental equipment by a preset time step, the data verification result of the preset communication channel is determined to indicate that the dental control data corresponding to the preset communication channel has passed the verification.

[0070] It is evident that implementation Figure 4 The described device improves the accuracy and reliability of dental control data verification by sequentially verifying the integrity and time step of the dental control data corresponding to the selected communication channels. When either the integrity or time step condition is not met, it can quickly switch to the dental control data parsing of another communication channel, ensuring that the dental device can successfully obtain the corresponding dental control data. This increases the probability of using accurate and reliable dental control data, thereby improving the control accuracy and stability of the dental device.

[0071] In an optional embodiment, each communication channel transmits dental control data with a unique timestamp each time; such as Figure 5 As shown, the device may also include; The judgment module 304 is used to determine, after the first determination module 303 determines the target dental control data for controlling the dental device based on the channel parsing result and the data listening result, whether there is other dental control data with the same time identifier as the dental control data corresponding to the target communication channel, and the target communication channel is a preset communication channel or other communication channels. The deletion module 305 is used to delete other dental control data when it is determined that other dental control data exists.

[0072] It is evident that implementation Figure 5 The described device accurately identifies duplicate dental control data by setting the same and unique timestamp for dental control data transmitted synchronously through each communication channel. This improves the accuracy and efficiency of data redundancy deduplication, and allows for the retention and execution of only the first received valid dental control data while deleting other redundant data with the same timestamp. This significantly reduces the risk of erroneous operations such as secondary acceleration and repeated start-stop of dental equipment, thereby improving the control safety of dental equipment. Furthermore, data redundancy deduplication reduces the data analysis load on the dental control end, greatly improving the control response speed of dental equipment.

[0073] Example 4 Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of another processing device for control based on multi-band fusion communication disclosed in an embodiment of the present invention. Figure 6 The described device can be applied in dental medical scenarios requiring dental control data transmission, such as tooth grinding and cutting. Figure 6 As shown, the device may include: The generation module 401 is used to generate dental control parameters that match the acquired dental control signals based on the type of dental control signals. The types of dental control signals include pedal depth control signal type and / or function control signal type. The modulation module 402 is used to modulate dental control parameters into dental control data that matches the communication channel by using the modulation frequency corresponding to each of the multiple communication channels; wherein the modulation frequency corresponding to each communication channel is different from each other; The transmitting module 403 is used to transmit the corresponding dental control data to the dental control terminal through each communication channel, so that the dental control terminal can listen to the dental control data through each communication channel.

[0074] It is evident that implementation Figure 6 The described device generates corresponding dental control parameters from the acquired dental control signals. Then, it modulates these parameters using the modulation frequency (operating frequency band) of the communication module corresponding to each communication channel, obtaining dental control data that matches the frequency domain of the corresponding communication channel. This modulated dental control data is then transmitted to the dental control terminal via the corresponding communication channel. The dental control terminal listens to the corresponding dental control data through each communication channel and controls the dental equipment based on the data listening results. This multi-communication-channel architecture modulates and transmits dental control parameters, achieving frequency domain complementarity, improving communication anti-interference capabilities and enhancing communication penetration. This improves the success rate, stability, accuracy, and reliability of dental control data transmission, reduces the packet loss rate, and ultimately enhances the accuracy, efficiency, and smoothness of dental equipment control.

[0075] In an optional embodiment, such as Figure 7 As shown, the device may also include; The monitoring module 404 is used to monitor the link status of all communication channels during the transmission of dental control data and obtain the link status monitoring results. The second determining module 405 is used to determine that all communication channels have lost data when the link status monitoring result indicates that no feedback response has been received from the dental control terminal after sending heartbeat packets to the dental control terminal for a consecutive preset number of times. The caching module 406 is used to cache the dental control data corresponding to each communication channel; The sorting module 407 is used to sort the dental control data corresponding to each communication channel in the cache according to a preset priority; The adjustment module 408 is used to perform adjustment operations on the communication parameters of each communication channel; The transmitting module 403 is also used to perform a retransmission operation on the dental control data corresponding to each sorted communication channel.

[0076] It is evident that implementation Figure 7 The described device can accurately identify packet loss in all communication channels within a short time by sending heartbeat packets at intervals, reducing the risk of dental equipment malfunction due to communication delays. Furthermore, by adjusting a combination of parameters—increasing the spreading factor of low-speed communication channels, enhancing the transmission power of high-speed communication channels, and reducing the transmission rate—it effectively penetrates obstructions such as metal dental X-ray machines and lead shielding walls, significantly improving the success rate of dental control data transmission in complex scenarios. Additionally, through hierarchical security, it prioritizes and retransmits control commands, ensuring high-risk operations are executed first. Moreover, it provides early warnings after multiple failed retransmissions, i.e., prolonged packet loss, forming a closed-loop protection system from fault detection to risk prevention. This significantly reduces the probability of communication-related medical accidents during dental procedures and improves the control safety and reliability of dental equipment.
