Detailed Implementation

[0031] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0032] Please see Figure 1The positioning tracking device 10 in this application includes a network communication module 11 and a positioning module 12. The network communication module 11 is configured to communicate with the positioning module 12 and the electronic device used by the user. The positioning module 12 is used to obtain the current location information of the positioning tracking device 10.

[0033] The network communication module 11 includes a Bluetooth communication device, which is used to communicate with electronic devices to determine whether the positioning and tracking device 10 has left a preset range based on the communication quality.

[0034] Specifically, the positioning and tracking device 10 in this application is generally installed on a carrier such as a pet or other creature or object that needs to be tracked. Its main purpose is to locate and track the current position of the carrier by performing its own positioning. If the carrier gets lost or leaves a preset range, it communicates with the user's electronic device to notify the user of the carrier's current status. Through the communication between the electronic device and the positioning and tracking device 10, the user can promptly learn whether the carrier has gotten lost or left the preset range, and also promptly obtain the carrier's current location information.

[0035] Furthermore, the electronic device includes a network communication module 11 and a positioning module 12. The main function of the network communication module 11 is to communicate with the user's electronic device, while the main function of the positioning module 12 is to obtain the positioning information of the positioning tracking device 10 itself. Since the positioning tracking device 10 is installed on the mounting carrier, the function of the positioning module 12 is equivalent to obtaining the current positioning information of the mounting carrier. The aforementioned positioning information can be transmitted to the electronic device through communication between the network communication module 11 and the electronic device, and the electronic device can also send relevant configuration information for tracking the mounting carrier to the positioning tracking device 10 through the aforementioned communication relationship.

[0036] Specifically, the network communication module 11 includes a Bluetooth communication device, which establishes a Bluetooth wireless connection with the user's electronic device. It should be noted that the aforementioned Bluetooth wireless connection is only one type of communication connection between the network communication module 11 and the user's electronic device. Even when the Bluetooth wireless connection is lost, other types of communication connections will still be maintained between the network communication module 11 and the user's electronic device. On one hand, the Bluetooth wireless connection between the electronic device and the Bluetooth communication device can be used to transmit data between the electronic device and the positioning and tracking device 10. That is, on the one hand, the positioning information obtained by the positioning and tracking device 10 can be sent to the electronic device via the Bluetooth communication device through the Bluetooth wireless connection; on the other hand, the electronic device can send tracking configurations to the positioning and tracking device 10 via the Bluetooth communication device through the Bluetooth wireless connection. The aforementioned tracking configurations generally include parameters such as the signal amplification and transmission power and receiving sensitivity of the Bluetooth communication device, used to control the communication distance of the Bluetooth communication.

[0037] Furthermore, since Bluetooth connectivity is significantly affected by the communication quality of Bluetooth wireless communication, and the communication quality of Bluetooth wireless communication is generally negatively correlated with the communication distance, the Bluetooth connection will be interrupted when the communication distance is too long. Therefore, the impact of whether the Bluetooth wireless connection is broken can be used to indicate whether the current installation carrier is within the preset range. If the Bluetooth connection between the electronic device and the Bluetooth communication device in the positioning and tracking device 10 is normal, the current installation carrier can be considered to be within the preset range. If the Bluetooth connection between the electronic device and the Bluetooth communication device is broken, the current installation carrier can be considered to have left the preset range. At this time, the electronic device can directly report the information that the installation carrier is missing to the user, so that the user can obtain the current location of the positioning and tracking device 10 based on other communication connections between the electronic device and the network communication module 11, thereby finding the location of the installation carrier.

[0038] Thus, the positioning and tracking device 10 in this embodiment can, on the one hand, obtain the current location information of the positioning and tracking device 10 in real time through the setting of the positioning module 12, thereby realizing the positioning of the pet's current location; on the other hand, it can communicate with the user's electronic device through the setting of the network communication module 11 to realize the parameter setting of the positioning process; and further, through the setting of the Bluetooth communication device, it can directly determine whether the pet is lost by using the quality of Bluetooth communication, without the need for judgment through the cloud server, thus improving the efficiency of judging whether the pet is lost.

[0039] Please see Figure 2 In some embodiments, the network communication module 11 includes a cellular network device CAT1, which is equipped with an embedded SIM device eSIM. The cellular network device CAT1 communicates with the cloud server through the embedded SIM device eSIM.

[0040] The Bluetooth communication device BLE and the cellular network device CAT1 communicate with each other via a preset protocol.

[0041] Specifically, based on the above embodiments, the network communication module 11, exemplarily, also includes a cellular network device CAT1. The cellular network device CAT1 is the core component of the network communication module 11 and even the entire positioning and tracking device 10. The cellular network device CAT1 has two main functions. One is to communicate with the cloud server via a cellular network to access the internet, so as to upload the positioning information of the positioning and tracking device 10 obtained by the positioning module 12 to the cloud server. Users can then obtain the positioning information of the positioning and tracking device 10 from the cloud server through an electronic device connected to the internet, thereby determining the location of the installation carrier.

[0042] Another function of the cellular network device CAT1 is to act as the main controller of the positioning and tracking device 10, coordinating the working states of the Bluetooth communication device BLE and the positioning module 12, thereby controlling the workflow of the positioning and tracking device 10. For example, in the above embodiment, the Bluetooth communication device BLE and the cellular network device CAT1 can establish a communication connection through a preset communication protocol. The cellular network device CAT1 controls the working state of the Bluetooth communication device BLE, such as controlling the opening and closing of the Bluetooth communication device BLE, and controlling whether the installation carrier has left the preset range by determining whether the Bluetooth connection needs to be switched on or off. The preset communication protocol is exemplarily the Universal Asynchronous Receiver / Transmitter (UART).

[0043] For example, the cellular network device CAT1 is equipped with an embedded SIM (eSIM) device, which communicates with the cloud server via cellular network signals. Generally, the eSIM is directly embedded as a chip onto the motherboard of the positioning and tracking device 10, and the cellular network device CAT1 is electrically connected to the eSIM. Before application, the operator service provider needs to be activated to access the internet via cellular signals by preloading a configuration file to the eSIM.

[0044] In some embodiments, the positioning module 12 includes a satellite positioning device GNSS, which is connected to the cellular network device CAT1 in the network communication module 11 via a preset protocol. The satellite positioning device GNSS is used to obtain the satellite positioning information of the positioning tracking device 10.

[0045] In some embodiments, the positioning module 12 further includes an ultra-wideband positioning device (UWB), which is connected to the cellular network device CAT1 in the network communication module 11 via a preset protocol. The UWB is used to obtain the positioning information of the positioning tracking device 10 when the satellite positioning signal is lower than expected.

[0046] In some embodiments, the positioning module 12 further includes an acceleration sensor G-sensor, which is connected to the cellular network device CAT1 in the network communication module 11 via a preset protocol. The acceleration sensor G-sensor is used to determine whether the positioning and tracking device 10 is currently moving.

[0047] Specifically, based on the above embodiments, the positioning module 12, exemplarily, includes three parts: a GNSS satellite positioning device, an UWB ultra-wideband positioning device, and a G-sensor. The GNSS satellite positioning device is used to obtain the satellite positioning of the positioning tracking device 10; the UWB ultra-wideband positioning device is used to obtain the ultra-wideband location information of the positioning tracking device 10 when the satellite signal is lower than expected; and the G-sensor is mainly used to supplement the positioning information obtained by the GNSS satellite positioning device and the UWB ultra-wideband positioning device. Its main function is to determine whether the positioning tracking device 10 is moving by measuring the acceleration of the positioning tracking device 10, which can be combined with the positioning information to improve the user's understanding of the actual location of the installation carrier.

[0048] Furthermore, the GNSS satellite positioning device is coordinated and controlled by the cellular network device CAT1 in the above embodiment. Its communication connection with CAT1 is similar to that of Bluetooth communication device BLE, relying on the UART protocol. The interval at which the GNSS acquires positioning information and its own operating status are coordinated and controlled by CAT1 via the UART protocol. The satellite positioning information acquired by the GNSS is also sent to CAT1 via the UART protocol. CAT1 then transmits the satellite positioning information to a cloud server via the internet through cellular network signals. Users can access the cloud server on their electronic devices via the internet to obtain the aforementioned satellite positioning information, thereby indirectly determining the satellite positioning information of the installation carrier.

[0049] The Ultra-Wideband (UWB) positioning device is also coordinated and controlled by the cellular network device CAT1 in the above embodiments. Its communication connection with CAT1 is similar to that of the Bluetooth communication device (BLE), relying on the UART protocol. The interval at which the UWB acquires positioning information and its own operating status are coordinated and controlled by CAT1 via the UART protocol. Furthermore, the UWB's acquired UWB positioning information is also transmitted to CAT1 via the UART protocol. CAT1 then transmits the UWB positioning information to a cloud server via the internet through cellular network signals. Users can access the cloud server on their electronic devices via the internet to obtain the aforementioned satellite positioning information, thereby indirectly determining the UWB positioning information of the installation carrier.

[0050] Ultra-wideband (UWB) positioning devices are primarily used for indoor or short-range positioning where satellite positioning signals are insufficient for the intended application. Generally, UWB positioning accuracy can reach the decimeter level. However, UWB functionality typically requires communication with the user's electronic devices. On some electronic devices that do not support UWB, UWB functionality can be extended by using external UWB devices. In areas with weak satellite positioning signals, such as inside buildings or indoors, communication between the user's electronic devices and the UWB on the positioning and tracking device 10 allows for the acquisition of UWB positioning information from the device, achieving decimeter-level or even centimeter-level positioning accuracy.

[0051] As for the G-sensor, it is also coordinated and controlled by the cellular network device CAT1 in the above embodiment. The communication connection between the G-sensor and the cellular network device CAT1 is generally achieved through the Inter-Integrated Circuit (I2C) protocol. Besides supplementing satellite positioning information or ultra-wideband positioning information by acquiring the acceleration of the positioning and tracking device 10, as described in the above example, the cellular network device CAT1 can also coordinate and control the operating frequencies of the Bluetooth communication device (BLE), the GNSS satellite positioning device, the UWB ultra-wideband positioning device, and itself based on the acquired acceleration information. For example, when the acceleration information acquired by the cellular network device CAT1 is 0, it indicates that the positioning and tracking device 10 is not currently moving. In this case, the cellular network device CAT1 can coordinate and control the Bluetooth communication device (BLE), the GNSS satellite positioning device, the UWB ultra-wideband positioning device, and itself to reduce their operating frequencies to save energy.

[0052] In some embodiments, the location tracking device 10 further includes a prompting module 13, which is controlled by the network communication module 11. The prompting module 13 is used to send a prompting message to the user when the location of the location tracking device 10 does not meet the preset conditions.

[0053] Specifically, based on the above embodiments, the location tracking device 10, exemplarily, further includes a prompting module 13 for sending a prompt message to the user when the location of the location tracking device 10 does not meet preset conditions. The preset conditions may be that the location of the location tracking device 10 is outside a preset range, or that the distance between the location tracking device 10 and the user's electronic device exceeds a preset threshold. That is, it can be understood that the main function of the prompting module 13 is to inform the user of the loss of the installation carrier or its location exceeding the preset range by sending a prompt message when the current location of the installation carrier exceeds the preset range, thereby improving the efficiency of the user in obtaining information about the loss of the installation carrier. Furthermore, the user can also indirectly control the prompting module 13 via control commands through a cloud server and a network communication module 11, increasing the visibility of the location tracking device 10 in the environment through sound and light, thereby improving the efficiency of the user in finding the installation carrier.

[0054] Furthermore, the operating state of the prompting module 13 is also controlled by the network communication module 11, specifically by the cellular network device CAT1 in the above embodiment. For example, when the Bluetooth connection between the Bluetooth communication device BLE and the user's electronic device is lost due to excessive distance, the cellular network device CAT1 directly controls the prompting module 13 to start working. As another example, when the user obtains the location information from the location tracking device 10 from the cloud server, the user can use their electronic device to send control commands to the cellular network device CAT1 for the prompting module 13 through the cloud server. After receiving the control commands, the cellular network device CAT1 controls the prompting module 13 to operate according to the commands.

[0055] In some implementations, the prompting module 13 includes a light-emitting diode (LED) and a buzzer (Beep). The LED is used to send prompt information to the user by emitting light, and the buzzer (Beep) is used to send prompt information to the user by emitting sound.

[0056] Specifically, based on the above implementation method, the prompting module 13 includes, for example, a light-emitting diode (LED) and a buzzer (Beep). The LED sends a prompt message to the user by emitting light, while the buzzer sends a prompt message to the user by emitting sound. It should be noted that the LED's light emission mode (e.g., whether it flashes, the frequency of flashing, the duration of continuous illumination, etc.) is affected by the control commands sent by the user. Similarly, the buzzer's sound emission mode (e.g., intermittent or continuous sound emission, the interval between intermittent sound emission, whether the pitch changes, the frequency of the sound, etc.) is also affected by the control commands sent by the user. The user can add LED light emission mode configurations and / or buzzer sound emission mode configurations in the sent control commands to increase the diversity of audio-visual information, thereby adapting to various situations in locating the installation carrier of the positioning and tracking device 10.

[0057] In some embodiments, the positioning and tracking device 10 further includes a power supply module 14, which provides power to the network communication module 11 and the positioning module 12.

[0058] In some embodiments, the power supply module 14 includes a battery device (Battery) and a voltage conversion device (LDO). The battery device (Battery) is used to directly power the cellular network device (CAT1) in the network communication module 11, and the voltage conversion device (LDO) is used to perform voltage conversion based on the battery device (Battery) to power the Bluetooth communication device (BLE) and the positioning module 12 in the network communication module 11.

[0059] In some implementations, the battery device is a rechargeable battery, which is connected to an external power source via a compatible charger.

[0060] The charger is connected to an external power source via a first preset interface;

[0061] The cellular network device CAT1 is equipped with a first preset interface.

[0062] Specifically, in the above embodiments, in addition to the above modules, in some examples, the positioning and tracking device 10 also includes a power supply module 14, which mainly supplies power to the network communication module 11 and the positioning module 12 to ensure the normal operation of the positioning and tracking device 10.

[0063] Generally, the power supply module 14 includes a battery device, which is directly connected to the cellular network device CAT1 in the network communication module 11 to directly power the cellular network device CAT1. However, since the power supply parameters of the satellite positioning device GNSS, the ultra-wideband positioning device UWB in the positioning module 12, and the Bluetooth communication device BLE in the network communication module 11 are generally different from those of the cellular network device CAT1, the battery device also includes a voltage converter LDO, which is connected to the battery device to transform the output voltage of the battery device and supply the transformed output voltage to the satellite positioning device GNSS, the ultra-wideband positioning device UWB, and the Bluetooth communication device BLE.

[0064] Further, please refer to Figure 2 ,exist Figure 2 In the illustrated scenario, the rated operating voltages of the GNSS satellite positioning device, the UWB ultra-wideband positioning device, and the BLE Bluetooth communication device are all 3.3V. The voltage conversion device LDO converts the output voltage of the battery device to 3.3V. The GNSS satellite positioning device, the UWB ultra-wideband positioning device, and the BLE Bluetooth communication device are connected in parallel to the voltage conversion device LDO.

[0065] Specifically, since the power supply parameters of the G-sensor are generally different from those of GNSS, UWB, and BLE, the G-sensor, for example, draws power directly from its connection to the cellular network device CAT1. Please continue reading. Figure 2 , Figure 2 In the case shown, the accelerometer G-sensor has a rated operating voltage of 1.8V, which is powered by the 1.8V voltage through its connection with the cellular network device CAT1.

[0066] Furthermore, the battery device is a rechargeable battery that can be charged via an external charger, external photovoltaic device, etc. Figure 2 In the example shown, the external charger Charger connects to an external power supply line or other external power source via a USB Type-C interface (corresponding to the first preset interface), thereby drawing power from the external power source and charging the battery device.

[0067] In particular, the cellular network device CAT1 is also equipped with a USB Type-C interface to facilitate connection between the cellular network device CAT1 and devices such as computers, so as to download and debug the operating program of the positioning and tracking device 10.

[0068] Based on the above embodiments, for the circuit structures of the USB Type-C interface, external charger charger, voltage conversion device LDO, light-emitting diode (LED), buzzer, embedded SIM device (eSIM), and cellular network device (CAT1) in the above embodiments, please refer to [link to relevant documentation]. Figures 3-9 .

[0069] For example, please refer to Figure 3 , Figure 3 The circuit structure of a USB Type-C interface is shown, using the MUP-U20401-2 model. On side B, the data communication pins DP2 / DN2 are connected to the negative terminal (USB_DP) and positive terminal (USB_DM) of the differential signal in USB data transmission via a connecting resistor. On side A, symmetrically, the data communication pins DP1 / DN1 are connected to the positive terminal (USB_DP) and negative terminal (USB_DM) of the differential signal in USB data transmission via a connecting resistor. The parameters of these connecting resistors are 0Ω ± 5% 1 / 16W, meaning a nominal value of 0Ω, a resistance tolerance of ±5%, and a rated power of 1 / 16W. The power supply pins VBUS1 to VBUS4 are all connected to the USB power supply terminal USB_VBUS. Pins CC1 and CC2 are grounded via preset CC resistors, with the CC resistor in this example having a parameter of 5.1kΩ + / -5% 1 / 16W.

[0070] Please see Figure 4 , Figure 4The circuit diagram of the charger charger is shown. The charger charger uses an ETA4056D6I charger control chip. Pin 1, VIN, is the power input pin, which receives the input voltage from the USB power supply terminal, USB_VBUS. The input voltage signal from USB_VBUS is filtered by a capacitor with parameters of 4.7μF±20% 6.3V and a capacitor with parameters of 100nF±10% 50V before being input to pin 1, VIN. The purpose of setting up two sets of capacitors with different capacitances and rated voltages is to adapt to input voltage signals with different parameters. Pin 2, STDBY, is the standby mode control pin, which can be used to control the chip to enter a low-power standby state. A light-emitting diode (LED) of model LTST-C193KGKT-5A is also connected to it to indicate the low-power standby state. A current-limiting resistor with parameters of 1kΩ±5% 1 / 16W is connected in series to prevent the LED from being burned out. Pin 3, STAT, is the status indicator pin. It indicates the current charging status by connecting an external LED (model LTST-C193KGKT-5A). A current-limiting resistor (1kΩ ± 5% 1 / 16W) is connected in series to prevent the LED from burning out. Pin 4, EN, is the enable pin, used to turn the charging function of the control chip on or off. Figure 4 As shown, pin 4 typically obtains the enable signal from the USB power supply terminal, USB_VBUS. Pin 5, GND, is the ground pin, providing an electrical reference ground for the chip. Pin 6, NTC, is the battery temperature monitoring pin, typically used to connect a negative temperature coefficient thermistor to prevent the battery from charging at excessive temperatures. Pin 7, ISET, is the charging current setting pin, which connects to a resistor with parameters of 22kΩ ± 5% 1 / 16W to set the charging current. Pin 8, BAT, is the charging pin, connected to the positive terminal of the battery assembly to charge the battery.

[0071] Please see Figure 5 , Figure 5The diagram illustrates the circuit structure of a voltage converter (LDO), which uses a WR1008-ADC06R control chip. Pin A1 is the output pin (OUT), which outputs a stable 3.3V voltage after conversion, providing this voltage to Bluetooth LTE (BLE), GNSS (GNSS), and UWB (UWB) communication devices. Pin A2 is the power input pin (IN), which draws the input voltage VBAT from the positive terminal of the battery. Pin B2 is the enable pin (EN), which draws the input voltage VBAT from the positive terminal of the battery as an enable signal to control the chip's operation. Pin C1 is the ground pin (GND), providing an electrical reference ground for the chip. Pin C2 is the bias pin (BIAS), which provides a suitable bias voltage to the chip's internal circuitry via an external capacitor. For example, the capacitor connected to the bias pin (BIAS) has parameters of 1μF ± 10% 6.3V. Pin B1 is the voltage adjustment pin (ADJ), which uses an external voltage divider resistor to form a voltage divider circuit, thereby adjusting the output voltage. For example, the voltage divider circuit connected to the voltage regulation pin mentioned above includes two branches. One branch includes a resistor with parameters of 20kΩ±1% 1 / 16W, which is ultimately connected to the output pin OUT. The other branch includes two resistors connected in series, which are ultimately grounded. The parameters of the two series resistors are 3.3kΩ±1% 1 / 16W and 270Ω±1% 1 / 16W, respectively. Furthermore, the battery voltage introduced by VBAT is filtered by a capacitor with parameters of 4.7μF±20% 6.3V and a capacitor with parameters of 100nF±10% 50V before being introduced to the input pin IN and the enable pin EN. The parallel capacitors of 120pF±5% 50V, 10μF±20% 6.3V, and 100nF±10% 50V work together to further filter out noise in the output voltage, making the output voltage smoother and more stable, thus meeting the power quality requirements of subsequent circuits.

[0072] Please see Figure 6 , Figure 6 A schematic diagram of the circuit structure of a light-emitting diode (LED) is shown. It should be noted beforehand that the positioning and tracking device 10 in the above embodiment generally includes three LEDs, and the circuit structure of each LED is as follows... Figure 6As shown. The light-emitting diode (LED) draws the battery voltage VBAT from the battery assembly via a current-limiting resistor. The parameters of the current-limiting resistor are 1kΩ ± 5% 1 / 16W. The LED device used is model LTST-C193KGKT-5A. The anode of the LED device is connected to the current-limiting resistor, and the cathode is connected to the collector of a transistor of model DTC043ZEBTL. The emitter of the transistor is grounded, and the base is connected to the LED ports LED1 / LED2 / LED3 on the cellular network device CAT1.

[0073] Please see Figure 7 , Figure 7 The circuit structure of the buzzer (Beep) is shown. The first terminal of the buzzer device in the Beep is connected to the battery pack (Battery) to obtain the battery voltage VBAT. The buzzer device is model HD-752501. A diode (model WSR4020D3A) is connected in reverse parallel across the buzzer device. This diode is used to prevent reverse current flow and protect the buzzer device.

[0075] Please see Figure 9 , Figure 9 The circuit structure of the cellular network device CAT1 is shown. The cellular network device CAT1 uses a control chip of model EG800Z_QuecOpen. This chip includes multiple pins. In the positioning and tracking device 10 of the above embodiment, the multiple pins not used in the control chip are all set to ground. The used pins can be divided into seven groups:

[0076] The first group corresponds to the UART communication function of CAT1 cellular network device, which is mainly used to establish communication relationships with Bluetooth communication device (BLE), satellite positioning device (GNSS), and ultra-wideband positioning device (UWB).

[0077] Specifically, the DBG_RXD pin is connected to the UWB_RXD port via a cross-line resistor with a parameter of 0Ω±5% 1 / 16W, and the DBG_TXD pin is connected to the UWB_TXD port via a cross-line resistor with a parameter of 0Ω±5% 1 / 16W, so as to establish a UART communication relationship with the ultra-wideband positioning device UWB.

[0078] The AUX_RXD pin is connected to the GNSS_RXD port via a jumper resistor with parameters of 0Ω±5% 1 / 16W, and the AUX_TXD pin is connected to the GNSS_TXD port via a jumper resistor with parameters of 0Ω±5% 1 / 16W, so as to establish a UART communication relationship with the satellite positioning device GNSS.

[0079] The MAIN_RXD pin is connected to the BLE_RXD port via a cross-line resistor with parameters of 0Ω±5% 1 / 16W, and the MAIN_TXD pin is connected to the BLE_TXD port via a cross-line resistor with parameters of 0Ω±5% 1 / 16W, so as to establish a UART communication relationship with the Bluetooth communication device BLE.

[0080] The second group corresponds to the connection relationship between the cellular network device CAT1 and the USB Type-C interface.

[0081] Specifically, the USB_DP pin connects to the positive differential signal terminal USB_DP in USB data transmission, thus connecting to the data communication pin DP in the USB Type-C interface. The USB_DM pin connects to the negative differential signal terminal USB_DM in USB data transmission, thus connecting to the data communication pin DM in the USB Type-C interface. Additionally, the USB_VBUS pin connects to the USB power supply terminal USB_VBUS to draw power within the Universal Serial Bus (USB) connection.

[0082] The third group corresponds to the connection relationship between the cellular network device CAT1 and the embedded SIM module eSIM. The USIM1_DATA pin corresponds to the USIM1_DATA port and is connected to the data input / output (IO) pin of the embedded SIM module eSIM. The USIM1_RST pin corresponds to the USIM1_RST port and is connected to the reset pin (RST) of the embedded SIM module eSIM. The USIM1_CLK pin corresponds to the USIM1_CLK port and is connected to the clock pin (CLK) of the embedded SIM module eSIM. The USIM1_VDD pin corresponds to the USIM1_VDD port and is connected to the power supply pin (VCC) of the embedded SIM module eSIM.

[0083] The fourth group corresponds to the connection relationship between the cellular network device CAT1, the LED, and the buzzer (Beep). The NET_STATUS pin is connected to the LED1 port, indicating the network connection status of CAT1 through the corresponding LED. The STATUS pin is connected to the LED2 port, indicating the current operating status of CAT1 through the corresponding LED. The PCM_DOUT pin is connected to the LED3 port, representing the pulse signal on the pin as light through the corresponding LED, thus indirectly indicating the pulse code data modulation status of CAT1. The MAIN_RI pin is connected to the BEEP port, and is used to indicate the ringing signal (Ring Indicator) to convert the ringing electrical signal into sound through the buzzer corresponding to the BEEP port.

[0084] The fifth group corresponds to the I2C communication connection between the cellular network device CAT1 and the accelerometer G-sensor. The I2C_SDA pin corresponds to the data transmission link, and the I2C_SCL pin corresponds to the clock information link.

[0085] The sixth group corresponds to the power supply of the cellular network device CAT1. Both VBAT1 and VBAT2 pins are connected to the battery module (Battery) and introduce the battery voltage VBAT. Before introducing the battery voltage VBAT, multiple capacitors filter the introduced voltage to remove power supply noise and achieve stable power supply. The capacitor parameters are 100μF±20% 10V, 100μF±10% 16V, 33pF±5% 50V, and 10pF±5% 50V, respectively.

[0086] The seventh group corresponds to the functions of the CAT1 cellular network device itself. The PWRKEY pin is used for power button control, controlling the CAT1's power on / off operation. The ANT_MAIN pin connects to the main antenna for wireless signal transmission and reception. When connected to the main antenna, two sets of 10pF±5% 50V filter capacitors and a 0Ω±5% 1 / 16W cross-line resistor are used as a filter circuit to filter the received wireless signal and ensure signal stability. The ADC0 pin is used for analog-to-digital conversion, enabling the acquisition of external analog signals. The VDD_EXT pin is the external power supply pin, used for the CAT1 cellular network device to supply power to external devices.
