[0043] The RC filter circuit includes a fourteenth resistor R14, a fifteenth resistor R15, a sixteenth resistor R16, a twelfth capacitor C12, a thirteenth capacitor C13 and a fourteenth capacitor C14. The TM13638 chip is connected to the STM32F103C8T6 serial port through the RC filtering circuit: the STB pin of the TM13638 chip is connected to the STB pin of the STM32F103C8T6 chip, and the STB pin of the TM13638 chip is connected to the 3.3V voltage through the fourteenth resistor R14, and the pin is also grounded through the twelfth capacitor C12; the CLK pin of the TM13638 chip is connected to the CLK pin of the STM32F103C8T6 chip, and the CLK pin of the TM13638 chip is connected to the 3.3V voltage through the fifteenth resistor R15, and the pin is also grounded through the thirteenth capacitor C13; the DIO pin of the TM13638 chip is connected to the DIO pin of the STM32F103C8T6 chip, and the DIO pin of the TM13638 chip is connected to the 3.3V voltage through the sixteenth resistor R16, and the pin is also grounded through the fourteenth capacitor C14.

[0044] Figure 6 4 is a circuit diagram of one of the keys of the key unit according to an embodiment of the present invention.

[0045] The key unit includes a plurality of keys, which are: a first-order key, a second-order key, a third-order key, a fourth-order key, a fifth-order key, a sixth-order key, a seventh-order key, an eighth-order key, a ninth-order key, a tenth-order key, and an eleventh-order key. The structures of the keys are the same. Figure 6The first-order keys are shown as an example.

[0046] Furthermore, the first-order button receives a level signal from the light driving unit (the first ULN2003N driving chip). When the first-order level receives a low-level signal, the light-emitting diode in the first-order button does not light up, and when the first-order level receives a high-level signal, the light-emitting diode in the first-order button lights up.

[0047] Furthermore, the first-order key is connected to the K1 pin and SEG1 pin of the TM1638 chip, the second-order key is connected to the K2 pin and SEG1 pin of the TM1638 chip, the third-order key is connected to the K3 pin and SEG1 pin of the TM1638 chip, the fourth-order key is connected to the K1 pin and SEG2 pin of the TM1638 chip, the fifth-order key is connected to the K2 pin and SEG2 pin of the TM1638 chip, the sixth-order key is connected to the K3 pin and SEG2 pin of the TM1638 chip, the seventh-order key is connected to the K1 pin and SEG3 pin of the TM1638 chip, the eighth-order key is connected to the K2 pin and SEG3 pin of the TM1638 chip, the ninth-order key is connected to the K3 pin and SEG3 pin of the TM1638 chip, the tenth-order key is connected to the K1 pin and SEG4 pin of the TM1638 chip, and the eleventh-order key is connected to the K2 pin and SEG4 pin of the TM1638 chip.

When the corresponding key is pressed, the state of the electrical signal on the pin connected to it changes. For example, when a person presses a first-order key, the level state of the K1 pin and the SEG1 pin changes, and this state change will continue until the key is released. Once the first-order key is released, the electrical signal state of the K1 pin and the SEG1 pin will return to the original level state, indicating that the key has been released. Based on this, the TM1638 chip can collect information about any key being pressed or released.

[0048] Figure 7 4 is a circuit diagram of a first ULN2003N driver chip according to an embodiment of the present invention.

[0049] like Figure 7 As shown, the input pin of the first ULN2003N driver chip is connected to the STM32F103C8T6 chip through the Button pipeline, and the output pin thereof is connected to the button unit.

[0051] Figure 8 is a circuit diagram of a second ULN2003N driver chip according to an embodiment of the present invention.

[0052] like Figure 8 As shown, the input pin of the second ULN2003N driver chip is connected to the STM32F103C8T6 chip through the Button pipeline, and the output pin thereof is connected to the button unit.

[0053] The input pins of the second ULN2003N driver chip connected to the STM32F103C8T6 chip include: a second I1 pin, a second I2 pin, a second I3 pin, and a second I4 pin.

[0054] Fig. 9 is a circuit diagram of a Bluetooth communication unit according to an embodiment of the present invention.

[0055] like Fig. 9 As shown, the Bluetooth communication unit includes a HY-40R204 chip and an LED light.

[0056] Among them, the HY-40R204 chip is connected to the STM32F103C8T6 chip through the TXD pin and the RXD pin, so that the HY-40R204 chip and the STM32F103C8T6 chip exchange data with the controller through the serial port, so that the MCU (i.e., the STM32F103C8T6 chip) obtains the instructions conveyed by the host computer. When the HY-40R204 chip and the STM32F103C8T6 chip exchange data, the LED light flashes to indicate the status. The host computer can be a computer, a mobile phone, a tablet computer and other devices.

[0057] Furthermore, the HY-40R204 chip also receives data from the STM32F103C8T6 chip, which includes data on the keys pressed by the person (patient). After receiving the data, the HY-40R204 chip transmits the data to the host computer.

[0058] Fig.10 is a circuit diagram of a power control circuit according to an embodiment of the present invention.

[0059] like Fig.10 As shown, the power control circuit includes a first MOS transistor Q1 and a second MOS transistor Q2.

[0060] Among them, the first MOS tube Q1 is a P-channel MOS tube, and the second MOS tube Q2 is an N-channel MOS tube.

The source of the first MOS tube Q1 is the power output terminal; the drain of the first MOS tube Q1 is the power input terminal, which is connected to the power supply interface of USB-A. The two ends of the twenty-third resistor R23 are respectively connected to the gate and source of the first MOS tube Q1.

[0061] It should be noted that when the SYS_POW_CTR pin of the DOXGS02S chip outputs a low level, the second MOS tube Q2 is turned off. At this time, the voltage difference between the gate and the source of the first MOS tube is small, and the first MOS tube is also turned off. When the SYS_POW_CTR pin outputs a high level, the second MOS tube Q2 is turned on. At this time, the gate of the first MOS tube is grounded, the voltage difference between the gate and the source is large, and the gate voltage of the first MOS tube is small. The first MOS tube Q1 is turned on, and the MCU and the keyboard scanning unit are both connected to the power supply. In particular, the SYS_POW_CTR power-on defaults to a low level, and after waking up, it is a high level, which is used to control the subsequent MCU and keyboard scanning unit to power on. Therefore, the DOXGS02S chip is first connected to the power supply, and then controls the MCU and the keyboard scanning unit to power on, thereby realizing time-sharing power-on.

[0062] In the above description of this specification, unless otherwise clearly specified and limited, the terms "fixed", "installed", "connected" or "connected" should be understood in a broad sense. For example, with regard to the term "connection", it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise clearly defined in this specification, those skilled in the art can understand the specific meanings of the above terms in this utility model according to the specific circumstances.

[0063] In addition, the terms "first" or "second" used in this specification to refer to numbers or ordinals are only used for descriptive purposes and cannot be understood as explicitly or implicitly indicating relative importance or implicitly indicating the number of technical features indicated.
