Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Therapeutic devices typically include display components, energy output components, and communication interaction components. Therefore, each device requires a corresponding control component to achieve coordinated control between these components. Existing control components for therapeutic devices are usually designed specifically for the type of device. This forces manufacturers to redesign the control components when designing similar products to ensure they can effectively perform their functions on that particular device. Furthermore, some therapeutic devices require encrypted identification, a function also integrated into the control component. Therefore, the encrypted identification methods differ even for different categories of the same type of therapeutic device, further increasing the complexity of the control component design.

[0037] Therefore, refer to Figures 1 to 5 This utility model proposes a core board for use in the control device of a treatment host. The control device includes a control base plate, on which a first interface and a functional circuit electrically connected to the first interface are provided. The core board includes:

[0038] A substrate, wherein a second interface is provided on the substrate, and the substrate is used to establish an electrical connection path with the control base plate via the second interface and the first interface;

[0039] Main control circuit 10, which is disposed on the substrate and electrically connected to the second interface;

[0040] A communication identification circuit 20 is disposed on the substrate and electrically connected to the main control circuit 10.

[0041] The core board encryption circuit 30 is disposed on the substrate and electrically connected to the main control circuit 10.

[0042] Wherein, when the substrate and the control base plate establish an electrical connection path through the first interface and the second interface, the main control circuit 10 is electrically connected to the functional circuit through the second interface and the first interface.

[0043] Understandably, in existing treatment units, the control unit is typically designed as an integrated unit. Therefore, when dealing with the same type of product, it is often necessary to design and manufacture multiple control units. For example, if product A has an additional authorization identification function compared to product B, then the control unit in product A will have additional authorization identification-related control functions compared to the control unit in product B. Because the control unit uses an integrated design, in addition to re-adding the authorization identification control program to the control module, the overall circuit layout also needs to be adjusted. Therefore, this approach suffers from a lack of flexibility.

[0044] It is understood that in this embodiment, the control device is divided into a core board and a control baseboard. The control baseboard has a first interface and functional circuits electrically connected to the first interface, including circuits required by the corresponding treatment host. The core board has a second interface for connecting to the first interface on the control baseboard, establishing an electrical connection path between the core board and the control baseboard when the first and second interfaces are electrically connected. The first and second interfaces can be connected using a surface-mount plug-in method or a gold-finger plug-in method. The plug-and-play connection effectively improves the flexibility of the connection between the core board and the control baseboard. Researchers can freely plug and unplug the second interface on the core board and the first interface on the control baseboard during research and testing.

[0045] In this embodiment, the main control circuit 10 can be implemented using a main controller, such as a System-on-Chip (SoC), Microcontroller Unit (MCU), Digital Signal Processor (DSP), or Field Programmable Gate Array (FPGA). Optionally, the main control circuit 10 can be implemented using an RK3568J chip.

[0046] In this embodiment, the communication identification circuit 20 can be implemented using a communication identification storage circuit. This circuit stores unique identifiers that allow network access. These identifiers are read when the communication network accesses the treatment host for authentication or loading configuration information, thereby confirming whether the desired communication network is permitted. If the identifier stored in the communication identification circuit 20 does not match the desired communication network, access to that network will be rejected to ensure the communication security of the treatment host. Further, the communication identification circuit 20 includes an identification chip U1, a first resistor R1, a second resistor R2, and a first capacitor C1. The power supply pin of the identification chip U1 is electrically connected to the power supply terminal and the first terminal of the first capacitor C1; the second terminals of the first resistor R1 and the second resistor R2 are electrically connected to the main control circuit 10; the protection pin of the identification chip U1 is electrically connected to the second terminal of the first capacitor C1 and the ground terminal; the clock pin of the identification chip U1 is electrically connected to the first terminal of the first resistor R1; and the data pin of the identification chip U1 is electrically connected to the first terminal of the second resistor R2. The identification chip U1 can be implemented using an AT24C02 chip and is electrically connected to the main control circuit 10 via an I2C bus to achieve data interaction. Furthermore, the AT24C02 chip has write protection and long-term data retention capabilities, effectively storing the identification information of the communication network. Additionally, the first capacitor C1 is used to filter the input voltage to ensure a stable power supply voltage for the identification chip U1. The first resistor R1 and the second resistor R2 are pull-up resistors to ensure stable transmission of data and clock signals.

[0047] In this embodiment, the core board encryption circuit 30 can be implemented using a hardware encryption coprocessor. The core board encryption circuit 30 includes an encryption chip U2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a sixth resistor R6, and a second capacitor C2. The power supply pin of the encryption chip U2 is electrically connected to the power supply terminal and the first terminal of the second capacitor C2; the second terminal of the second capacitor C2 is electrically connected to the ground terminal; the clock pin of the encryption chip U2 is electrically connected to the first terminal of the third resistor R3; the data pin of the encryption chip U2 is electrically connected to the first terminal of the fourth resistor R4; the second terminal of the third resistor R3 is electrically connected to the first terminal of the fifth resistor R5; the second terminal of the fourth resistor R4 is electrically connected to the first terminal of the sixth resistor R6; the second terminal of the fifth resistor R5 is electrically connected to the main control circuit 10; and the second terminal of the sixth resistor R6 is electrically connected to the main control circuit 10. The encryption chip U2 can be implemented using an ATECC608B-SSHDA-T to support various encryption algorithms, such as AES, ECC, and SHA. The encryption chip U2 is electrically connected to the main control circuit 10 via a UART bus for data exchange. The second capacitor C2 filters the input voltage to ensure a stable power supply voltage for the identification chip U1. It's important to note that the encryption process of the core board's encryption circuit 30 involves specific software programming and API calls. In practical applications, developers need to write code to interact with the encryption chip U2 to set keys, select appropriate encryption algorithms, and send and receive data. Understandably, the encryption chip U2 itself does not directly encrypt data; rather, it acts as a hardware accelerator, helping the main control circuit 10 perform encryption operations faster and more securely.

[0048] Optionally, the core board encryption circuit 30 also includes a tag circuit for storing information such as the batch number, serial number, and production date of the core board. This tag circuit can be implemented using an RFID tag circuit, a short-range communication tag circuit, or a tag storage circuit. Taking an RFID tag circuit as an example, a sensing chip is set on the core board, and the relevant information of the core board can be obtained by using an identification device with an RFID chip. If a tag storage circuit is used, the relevant information of the core board can be displayed on the display component of the treatment host by controlling it.

[0049] Optionally, the functional circuit includes a baseboard encryption circuit 70, which is electrically connected to the main control circuit 10 via the first interface and the second interface.

[0050] In this embodiment, the baseboard encryption circuit 70 can be implemented using a hardware encryption coprocessor, a secure microcontroller, a cryptographic accelerator, etc. The control baseboard is equipped with functional circuits, including various working circuits with different functions. These different working circuits generate various types of data during operation and input them to the main control circuit 10 via the first and second interfaces. Therefore, to encrypt the data generated by the control baseboard, a baseboard encryption circuit 70 needs to be installed on the control baseboard to encrypt the baseboard's working data. The baseboard encryption circuit 70 is electrically connected to the first interface via a UART bus, and is electrically connected to the main control circuit 10 via the first and second interfaces.

[0051] In this embodiment, a core board with a second interface on its substrate is used, allowing the core board to be electrically connected to a first interface on the control base plate via the second interface, facilitating plug-in / plug-out testing between the core board and the control base plate. The control base plate also includes functional circuits electrically connected to the first interface. The main control circuit 10, mounted on the substrate, establishes an electrical connection with the functional circuits via the first and second interfaces, enabling the main control circuit 10 on the core board to control the functional circuits on the control base plate and acquire data. Furthermore, the core board includes a communication identification circuit 20 and a core board encryption circuit 30. The communication identification circuit 20 verifies whether the accessed network conforms to the identification information to ensure network access security; the core board encryption circuit 30 encrypts the core board's operating data to improve data security and reliability. Therefore, the core board proposed in this invention can effectively improve the security and flexibility of the control device in the treatment host.

[0052] refer to Figure 4 In one embodiment of the present invention, the core board further includes a voltage conversion circuit 40, which is electrically connected to the main control circuit 10. The voltage conversion circuit 40 is used to convert the input first voltage into a second voltage and output it.

[0053] In this embodiment, the voltage conversion circuit 40 can be implemented using an AC / DC circuit, a DC / DC circuit, or a low-dropout linear regulator. It is understood that the main power supply connected to the treatment unit is 220V AC mains voltage. The treatment unit can first rectify and step down the input 220V AC voltage using a power adapter or its internal power management device before outputting it. The input terminal of the voltage conversion circuit 40 on the core board is electrically connected to the processed power input terminal to obtain the processed first voltage. By converting the input first voltage, a second voltage is output to the main control circuit 10 and other circuits on the core board that require power. Examples include the communication identification circuit 20 and the core board encryption circuit 30. Furthermore, the voltage conversion circuit 40 can be implemented using a PMIC circuit. The PMIC circuit can start and stop different power rails in the correct sequence to ensure correct start-up and shutdown of various circuits on the core board. In addition, the PMIC circuit provides overvoltage protection, undervoltage lockout, and overcurrent protection functions to prevent power failure from damaging the core board. Furthermore, PMIC circuits integrate multiple power management functions into a single chip, reducing the number of external components, saving substrate space, and simplifying the design process.

[0054] refer to Figure 4 In one embodiment of this utility model, the core board further includes a storage circuit 50, which is electrically connected to the main control circuit 10.

[0055] In this embodiment, the main control circuit 10 needs to quickly access a large amount of data to perform tasks and run the operating system and applications when processing data, and sets up corresponding storage space to store a large amount of data for easy access when needed. Optionally, there are multiple storage circuits 50, and the multiple storage circuits 50 include at least an LPDDR4 circuit 51 and an eMMC circuit 52. It is understood that in order to assist the main control circuit 10 to work quickly and stably, multiple storage circuits 50 need to be set in the control board. Among them, the LPDDR4 circuit 51 is a high-speed synchronous dynamic random access memory used to store running programs and data. In the core board, LPDDR4 is a low-power version of the fourth-generation DDR memory standard, which has faster speed and lower power consumption. For a SoC like the RK3568J chip, memory is a very important component because it needs to quickly access a large amount of data to perform tasks and run the operating system and applications. The LPDDR4 circuit can meet the high-speed data exchange requirements of the RK3568J chip while reducing overall power consumption. The eMMC circuit 52 is an integrated flash memory that integrates NAND flash memory and a controller. Within the core board, the EMMC circuit 52 provides a large capacity of non-volatile storage space for storing operating system images, applications, files, and other persistent data.

[0056] refer to Figure 4 and Figure 5 In one embodiment of the present invention, the core board further includes a core board communication circuit 60, which is electrically connected to the main control circuit 10.

[0057] In this embodiment, the core board communication circuit 60 can be implemented using an Ethernet transceiver circuit, a wireless network communication circuit, etc. Taking an Ethernet transceiver circuit as an example, the core board communication circuit 60 is electrically connected to the main control circuit 10 via an I2C bus. The Ethernet transceiver circuit is mainly used to convert digital signals into a form suitable for transmission over a physical medium and to convert received physical signals into digital signals. When the main control circuit 10 needs to send data to the network, it passes the data packet to the MAC layer. The MAC layer is responsible for encapsulating the data packet into a frame format and sending it to the PHY layer through interfaces such as MII / RMII / GMII. The PHY layer then converts the data frame into an electrical signal that can be transmitted over a cable. The process of receiving signals is the reverse: the PHY layer converts the received electrical signal back into a data frame, and then the MAC layer decapsulates the data frame and passes it to the main control circuit 10. Furthermore, the Ethernet transceiver circuit can also electrically connect its first end to the wireless communication module in the control baseboard and its second end to the main control circuit 10, thereby achieving the technical effect of wireless communication.

[0058] Optionally, the functional circuit further includes a baseboard communication circuit 90, which is electrically connected to the main control circuit 10 via the first interface and the second interface.

[0059] In this embodiment, the baseboard communication circuit 90 can be implemented using either a wireless communication circuit or a wired communication circuit. By providing a communication circuit on the control baseboard, various communication needs of the treatment host can be met. For example, when the core board communication circuit 60 in the core board uses an Ethernet transceiver circuit, the baseboard communication circuit 90 can be implemented using a WIFI communication circuit 91 and a 4G communication circuit 92 module, thereby enabling free selection between wired and wireless communication. Optionally, there can be multiple baseboard communication circuits 90, each including at least a WIFI communication circuit 91 and a 4G communication circuit 92. By employing multiple baseboard communication circuits 90, the problem of communication interruption caused by the communication quality of one method failing to meet communication requirements can be avoided. For example, when the WIFI communication circuit 91 has poor communication quality, it will automatically switch to the 4G communication circuit 92 to ensure data interaction between the treatment host and other terminals or the cloud; when the communication quality of the WIFI communication circuit 91 recovers, it will switch back to the WIFI communication circuit 91 from the 4G communication circuit 92.

[0060] refer to Figure 4 In one embodiment of this utility model, the second interface includes a gold finger.

[0061] In this embodiment, the second interface on the substrate is a gold finger. Therefore, the first interface in the control base plate can be a slot for the corresponding contact, so as to facilitate data interaction and plug-in connection between the core board and the control base plate.

[0062] This utility model also proposes a control device, which includes a control base plate and a core board as described in any of the above claims; wherein, the control base plate is provided with a first interface and a functional circuit electrically connected to the first interface. It is worth noting that, since the control device of this utility model is based on the aforementioned core board, the embodiments of the control device of this utility model include all the technical solutions of all the embodiments of the aforementioned core board, and the achieved technical effects are exactly the same, and will not be repeated here.

[0063] refer to Figure 5 Optionally, the functional circuit includes an authorization identification circuit 80, which is electrically connected to the main control circuit 10 via the first interface and the second interface.

[0064] In this embodiment, the authorization identification circuit 80 can be implemented using a radio frequency identification (RFID) circuit, a near-field communication (NFC) circuit, or the like. The treatment host has a corresponding authorization identification area to allow operators to use authorization cards or devices for identification, thereby activating the treatment host. Taking the RFID circuit 80 as an example, an authorization card is provided. The authorization card contains a sensing chip, and the authorization identification circuit 80 on the control board of the treatment host has a reader. When the authorization card approaches the authorization identification area, the sensing chip inside the card receives an electromagnetic wave signal. The energy obtained from the induced current activates the sensing chip circuit, and the information stored in the sensing chip is then sent to the reader in the form of electromagnetic waves. This allows the treatment host to confirm whether the information on the authorization card corresponds to the authorization information in the treatment host.

[0065] Optionally, the functional circuit further includes an audio power amplifier circuit 100, which is electrically connected to the main control circuit 10 via the first interface and the second interface.

[0066] In this embodiment, the audio amplifier circuit 100 can be implemented using a Class A amplifier, Class B amplifier, Class D amplifier, etc. The audio amplifier circuit 100 is primarily used to amplify the amplitude or power of the input signal so that it can drive a speaker or other load device to output a speech signal. The audio amplifier circuit 100 receives audio signals from the audio source device and amplifies these signals to a level sufficient to drive a speaker. It is understood that the original audio signal is usually a weak electrical signal, insufficient to drive a speaker to produce a sufficiently loud sound. Furthermore, the audio amplifier circuit 100 may also include signal processing functions such as equalizers and filters, which help adjust the audio spectrum to make the output sound clearer. By incorporating the audio amplifier circuit 100 into the control panel, the accuracy of human-machine interaction between the treatment host and the operator is improved.

[0067] Optionally, the functional circuit further includes a touch display circuit 110, which is electrically connected to the main control circuit 10 via the first interface and the second interface.

[0068] In this embodiment, the touch display circuit 110 can be implemented using both a touch circuit and a display circuit. The touch circuit receives touch signals and outputs them to the main control circuit 10. After processing by the main control circuit 10, the signals are output to the display circuit, enhancing the interactivity between the operator and the treatment host. The operator can issue various operation commands through the touch circuit and obtain corresponding information, such as the working status of the treatment host, through the display circuit.

[0069] Optionally, the functional circuit further includes a clock circuit 120, which is electrically connected to the main control circuit 10 via the first interface and the second interface.

[0070] In this embodiment, the clock circuit 120 can be implemented using a crystal oscillator, an RC oscillator, an RTC circuit, etc. Taking the clock circuit 120 using an RTC circuit as an example, the RTC circuit can continue to operate when the main power is off or the main control circuit 10 enters a low-power mode, ensuring the continuity and accuracy of time information. The RTC circuit provides an uninterrupted time reference, maintaining time continuity even when the device is powered off or in sleep mode. This is crucial for applications requiring continuous time tracking, such as logging, scheduled tasks, and alarm clock functions. Furthermore, when the treatment host starts up, the RTC circuit can provide accurate time information to help the operating system or other application software perform initialization settings. For example, a file system may need the current time to record the creation or modification time of files.

[0071] This utility model also proposes a treatment host, which includes the control device as described above. It is worth noting that since the control device of this utility model is based on the aforementioned control device, the embodiments of the treatment host of this utility model include all the technical solutions of all embodiments of the aforementioned control device, and the achieved technical effects are completely the same, and will not be repeated here.
