[0003] Current trackers are limited by size and weight requirements, resulting in generally small battery capacities and limited lifespans. Furthermore, trackers may traverse areas with poor GPS and wireless communication signal coverage during movement; uploading data in these areas further increases power consumption, significantly shortening the tracker's battery life.

By setting the GNSS module to periodically sleep to reduce energy consumption, and the GNSS module receiving GNSS signals in the non-sleep state while simultaneously checking the network environment through the CAT1 module, the excess computing power of the GNSS module is fully utilized to identify whether the measured object is resting and whether the network environment is suitable for data transmission.

[0033] like Figures 1 to 2 As shown, this application provides a tracking and positioning device, which is disposed on the object being measured. The tracking and positioning device includes:

[0034] Battery module 100;

[0035] A GNSS module 200 connected to the battery module 100 is configured to periodically hibernate to receive GNSS signals when not in hibernation, and to output a start signal when the measured object is determined to be in a preset resting state based on the GNSS signals; and

[0036] CAT1 module 300 is connected to the power module and GNSS module 200 and is used to perform network check and output network check information when a start signal is received.

[0037] GNSS module 200 is also used to upload positioning data via CAT1 module 300 when the network environment is determined to be suitable for data transmission based on network inspection information.

[0038] In practice, the battery module 100 is used to supply power to the GNSS module 200 and the CAT1 module 300. The battery module 100 may be any one of, including but not limited to, a disposable battery or a rechargeable battery 110.

[0039] For example, the battery module 100 includes a rechargeable battery 110 and a charging interface 120. The rechargeable battery 110 is connected to the GNSS module 200 and the CAT1 module 300 to supply power to them. The charging interface 120 is connected to the rechargeable battery 110. In some embodiments, the charging interface 120 may be at least one of, but not limited to, a USB charging interface 120 and a Type-C interface.

[0040] As one possible implementation, the rechargeable battery 110 is a solar cell that directly generates and stores electricity from sunlight, effectively improving battery life.

[0041] The GNSS (Global Navigation Satellite System Receiver) module can receive signals from multiple global navigation satellite systems (such as GPS, GLONASS, Galileo, or BeiDou) and determine the user's location, speed, and time information by calculating the signal transmission time difference.

[0042] Optionally, the GNSS module 200 can use a commercially available GNSS receiver, as long as it can provide positioning, low-power sleep / wake-up, and OpenCPU functions, without limitation. Optionally, the GNSS module 200 has a data interface, which includes, but is not limited to, at least one interface such as RS232, RS485, RS422, TTL, SPI, and I2C, without limitation.

[0043] In some embodiments, the GNSS module 200 includes a GNSS chip 210 and a GNSS antenna 220. The GNSS chip 210 has a power supply port, an antenna connection port, and a data transmission port. The power supply port is connected to the battery module 100, the antenna connection port is connected to the GNSS antenna 220, and the data transmission interface is connected to the CAT1 module 300. In addition to receiving GNSS signals, this application further utilizes the spare computing power and storage space of the GNSS chip 210. That is, the GNSS chip provides the functions of a main control MCU while also handling positioning.

[0044] The GNSS chip 210 stores the positioning data in its internal flash memory. Optionally, the GNSS module 200 also compresses and saves the latitude and longitude data of the GNSS signal according to a preset compression algorithm.

[0045] Optionally, the compression algorithm includes at least one of LZM and LZMA.

[0046] Based on the regularity of the latitude and longitude data carried by GNSS signals, the latitude and longitude are first converted from degree-minute format to degree format. Then, a specific compression algorithm is used to compress the latitude and longitude data before saving it to the internal flash memory of the GNSS chip 210. For example, the GNSS chip 210 can provide 512KB of flash space. Combined with the compression algorithm, 512KB of space can store data for more than 480,000 positioning points, eliminating the need for additional storage area to store offline data, thus controlling cost and size.

[0047] The GNSS module 200 is configured to sleep at regular intervals. For example, the GNSS chip 210 can be periodically woken up by an RTC (Real-Time Clock). An RTC is an integrated circuit that provides a precise time reference through a crystal oscillator to enable rapid positioning in a hot-start manner.

[0048] The GNSS module's 200-cycle wake-up function primarily relies on the GNSS chip 210. In 3.3V mode, the GNSS chip 210 consumes 9uA in DataBackup mode and 34mA in normal operation. When the GNSS chip 210 enters DataBackup mode, only the RTC function and backup RAM power are retained. The RTC wakes up the GNSS chip 210 at a preset time, relying on the ephemeris stored in the backup RAM to achieve rapid positioning, approximately 25 seconds faster than a pure cold start. With the same battery capacity, actual tests show that this can extend the device's battery life by 40% to 50%.

[0049] In practice, tracking and positioning devices are typically mounted on moving objects, such as cars, drones, birds, wild animals, and various pets, which carry the devices with them. For example, if mounted on a bird, the bird will pass by various base stations during flight. If the tracking and positioning device is constantly uploading data, it will switch between base stations, increasing power consumption.

[0050] This application configures the GNSS module 200 to periodically wake up. During the wake-up period, the GNSS module 200 determines whether the measured object is in a stationary state based on positioning data. If the measured object is determined to be in a stationary state, the CAT1 module 300 is activated for network access detection. The CAT1 module 300 is a classification standard for user terminal equipment under 4G communication networks (LTE), defined by the 3GPP organization, and mainly used for low-speed scenarios such as the Internet of Things (IoT). The CAT1 module 300 supports basic communication and GPS positioning, TCP / IP, HTTP, MQTT, and other protocols, meeting the networking needs of smart devices.

[0051] In some embodiments, a resting state refers to the measured object moving within a specified range within a specified time. For example, if the measured object is a bird, the bird can be considered to be in a resting state if the bird's movement within 5 seconds does not exceed 5 meters.

[0052] It should be noted that the specified time of 5 seconds and the specified range of 5 meters mentioned above are illustrative examples of embodiments of this application, and not specific limitations on this application. In some other embodiments, the specified time and specified range can be set according to the actual environment and usage requirements. For example, the specified time can be 3 seconds, 4 seconds, 6 seconds, 7 seconds or other time values, and the specified range can be 2 meters, 3 meters, 4 meters, 6 meters, 10 meters or other distance range values, without limitation.

[0053] Optionally, the CAT1 module 300 can be a common CAT1 module 300 on the market, as long as it can provide wireless communication data interaction function, without being limited to a specific model or 2G / 3G / 4G / 5G or other wireless communication technologies.

[0054] Optionally, the tracking and positioning device also includes a built-in network antenna 310, which is connected to the CAT1 module 300. The built-in network antenna 310 can enhance the directionality or focusing of the signal, improve connection stability and signal coverage, and reduce power outages.

[0055] When it is determined that the environment of the object being measured is suitable for uploading data, the GNSS module 200 uploads the stored positioning data through the CAT1 module 300, for example, to the backend server 500.

[0056] The tracking and positioning device provided in this application includes a battery module 100; a GNSS module 200 connected to the battery module 100, the GNSS module 200 being configured to periodically go into sleep mode to receive GNSS signals when not in sleep mode, and output a start signal when it is determined based on the GNSS signals that the measured object is in a preset resting state; and a CAT1 module 300, the CAT1 module 300 being connected to the power module and the GNSS module 200, used to perform a network check and output network check information when the start signal is received; the GNSS module 200 is also used to upload positioning data through the CAT1 module 300 when it is determined based on the network check information that the network environment is suitable for data transmission. By setting the GNSS module to sleep periodically to reduce energy consumption, the GNSS module 200 receives GNSS signals when it is not in sleep mode. At the same time, the CAT1 module 300 checks the network environment and makes full use of the spare computing power of the GNSS module 200 to identify whether the measured object is stationary and whether the network environment is suitable for data transmission. Positioning data is uploaded only when the network environment is good and suitable for data transmission, avoiding uploading data when the network environment is not suitable for data transmission, which would increase energy consumption. This achieves low power consumption, saves costs, and increases the reliability and service life of the tracking and positioning device.

[0057] In some embodiments, the CAT1 module 300 is provided with a card slot for inserting a SIM card and / or an eSIM card. A SIM (Subscriber Identity Module) card is an IC card held by a mobile user in the GSM system, and an eSIM card is an electronic SIM card. The CAT1 module 300 can only connect to the GSM network and then connect to the backend server 500 through a SIM card and / or an eSIM card.

[0058] Secondly, this application also provides a positioning system, comprising:

[0059] Backend server 500; and

[0060] The aforementioned tracking and positioning device is wirelessly connected to the backend server 500.

[0061] The tracking and positioning device includes a GNSS module 200, a CAT1 module 300, and a battery module. The GNSS module 200 has a GNSS chip 210. For the sake of convenience and brevity, the structure and implementation principle of the GNSS module 200, CAT1 module 300, and battery module described above can be referred to the corresponding structure and implementation principle in the foregoing embodiments, and will not be repeated here.

[0062] The GNSS chip 210 serves as the main controller of the system, primarily responsible for functions such as positioning, periodic wake-up, data compression, data storage, motion state detection, waking up the CAT1 module 300, deciding when to transmit data to the background, and controlling the CAT1 module to transmit data.

[0063] This application fully utilizes the surplus computing power and storage space of the GNSS chip 210. While providing positioning capabilities, the GNSS chip 210 also provides the functions of a main control MCU. The GNSS chip 210 uses RTC for periodic wake-up, achieving rapid positioning via a hot-start method. The positioning data is compressed using a compression algorithm and stored in the internal flash memory of the GNSS chip 210. When the algorithm detects that the object being measured has stopped and the wireless network signal is good, the CAT1 module 300 is then activated to transmit offline data to the background service. This achieves the goals of saving power consumption, extending battery life, and ensuring the integrity of data transmission.

[0064] Optionally, the specific functions of each module in the system are described as follows:

[0065] Device self-test: The self-test includes GPS satellite search check, CAT1 network connection check, battery power check, etc. The self-test results are uploaded to the backend server 500 via wireless network, and also output via debug serial port.

[0066] GPS Positioning: The main function of the GPS positioning module is to quickly provide information such as latitude, longitude, altitude, and speed. Because it uses the OpenCPU solution of the GNSS chip 210, the positioning information is not output to the serial port but is stored in memory.

[0067] Data compression: Based on the regularity of latitude and longitude data, the latitude and longitude are first converted from degree format to degree format, and then a specific compression algorithm is used to compress the latitude and longitude data.

[0068] Data storage: The GNSS chip 210 has ample internal flash space, providing an additional 512KB of flash space on top of the OpenCPU. Combined with compression algorithms, this 512KB space can store over 480,000 location point data points.

[0069] On-site inspection: The main function of on-site inspection is to quickly check the network environment and provide feedback on the current network status and CSQ.

[0070] Data Upload: This section includes two parts: decision-making and data upload. The decision-making process primarily uses GPS-provided speed and latitude / longitude information to determine if the measured object is in a stationary state. If it is stationary, the CAT1 module 300 is activated to check network connectivity and CSQ (Customer Service Queues) to further determine if data transmission is suitable. The main rationale is that the CAT1 module 300's communication is a major load on the power supply; to extend battery life, data transmission should be avoided as much as possible when network signal is poor. This application uses GPS speed and location checks, as well as network connectivity checks, to select a time when the measured object is stationary in an area with good network signal for data transmission, achieving an optimal solution for power consumption and functionality.

[0071] The tracking and positioning device provided in this application includes a battery module 100; a GNSS module 200 connected to the battery module 100, the GNSS module 200 being configured to periodically go into sleep mode to receive GNSS signals when not in sleep mode, and output a start signal when it is determined based on the GNSS signals that the measured object is in a preset resting state; and a CAT1 module 300, the CAT1 module 300 being connected to the power module and the GNSS module 200, used to perform a network check and output network check information when the start signal is received; the GNSS module 200 is also used to upload positioning data through the CAT1 module 300 when it is determined based on the network check information that the network environment is suitable for data transmission. By setting the GNSS module to sleep periodically to reduce energy consumption, the GNSS module 200 receives GNSS signals when it is not in sleep mode. At the same time, the CAT1 module 300 checks the network environment and makes full use of the spare computing power of the GNSS module 200 to identify whether the measured object is stationary and whether the network environment is suitable for data transmission. Positioning data is uploaded only when the network environment is good and suitable for data transmission, avoiding uploading data when the network environment is not suitable for data transmission, which would increase energy consumption. This achieves low power consumption, saves costs, and increases the reliability and service life of the tracking and positioning device.

[0072] Thirdly, this application also provides an electronic device, including the tracking and positioning device as described above.

[0073] Those skilled in the art will clearly understand that, for the sake of convenience and brevity, the structure and implementation principle of the electronic device described above can be referred to the corresponding structure and implementation principle in the foregoing embodiments, and will not be repeated here.
