[0041] Example 1

[0042] An integrated indoor and outdoor positioning device includes a main control module 1, a satellite signal receiving module, a short-distance positioning module, a latitude and longitude information calculation module, a long-distance communication module and a server module. The satellite signal receiving module is used to receive satellite information for outdoor positioning, the longitude and latitude information calculation module is used to calculate the longitude and latitude information corresponding to the satellite information, the long-distance communication module is used to transmit the longitude and latitude information to the server module, and the short-distance positioning module is used for indoor positioning. The connection relationship between the various components of this embodiment is as follows: Figures 1 to 4 shown.

[0043] This utility model integrates multiple positioning technologies, covering both indoor and outdoor positioning scenarios. The satellite signal receiving module uses a traditional GNSS positioning module, which supports multiple positioning systems such as GPS, Glonass, Galileo, Beidou, QZSS, etc. When the device is in an open outdoor environment, it can obtain accurate latitude and longitude information worldwide for outdoor positioning.

[0044] Indoor positioning uses Bluetooth Beacon positioning. The device can search for nearby Bluetooth Beacon MAC addresses. By uploading the Bluetooth Beacon MAC address to the background, the device's location information can be obtained for indoor positioning.

[0045] WiFi positioning can also be used for indoor positioning. The device can search for nearby WiFi MAC addresses and upload the searched MAC address information to the background to obtain the device's location information, which can also be used for indoor positioning.

[0046] There are two versions of the utility model device, the difference is that they respectively adopt two GNSS positioning technologies. Specifically, version A adopts Dafa Technology's low-power GNSS positioning chip 3. After the GNSS positioning chip 3 receives satellite information through the antenna, it locally calculates the longitude and latitude information. The longitude and latitude information is transmitted to the server through the LoRaWAN network. Version B adopts Semtech's new generation LoRa chip 2, which has a built-in GNSS receiving function. It can receive satellite information through the antenna, and then transmit it to the server through the LoRaWAN network. The server calculates the longitude and latitude information, further reducing the power consumption of the device. In this embodiment, the above-mentioned version B is adopted, that is, the satellite signal receiving module is built into the LoRa chip 2, that is, the positioning module of Example 2 is the positioning module in the LoRa chip 2, such as Figure 1 As shown. The new generation LoRa chip 2 from Semtech is used, which has a built-in GNSS receiving function. After receiving satellite information through the antenna, it is transmitted to the server through the LoRaWAN network. The server calculates the longitude and latitude information, further reducing the power consumption of the device. The new generation LoRa transceiver has built-in WiFi receiving function and GNSS receiving function, which is used for LoRa communication, WiFi positioning function, and GNSS signal receiving function in version B. The satellite signal receiving module is built into the LoRa chip 2, and the long-distance communication module is a LoRaWAN communication module. GNSS positioning supports multiple positioning systems such as GPS, Glonass, Galileo, Beidou, QZSS, etc. When the device is in an open outdoor environment, accurate longitude and latitude information can be obtained globally.

[0047] The main control module 1 is the main control chip of the device, and has a built-in BLE function. It serves as the processor of the entire device and is responsible for connecting to the mobile phone APP via Bluetooth to configure the device.

[0048] In some embodiments, the positioning device further includes an offline storage module, which is used to store the positioning information of the positioning device inside the device when the positioning device is not within the coverage of the long-distance communication module, and upload the positioning information stored in the offline storage module to the server through the long-distance communication module when the device re-enters the coverage of the long-distance communication module. If the device is temporarily out of the coverage of the LoRaWAN network, the positioning information can be stored inside the device and uploaded to the background after the device is back online.

[0049] In some embodiments, the positioning device further includes a three-axis accelerometer for real-time monitoring of the motion state of the positioning device, and triggering a positioning action and recording an event when a preset motion state is detected. A three-axis acceleration sensor chip 15 is used to measure three-axis acceleration data, and can distinguish the motion state of the device, device motion, device stop motion, device fall, etc., so as to perform a positioning action.

[0050] Optionally, the positioning device also includes a temperature sensor and a light sensor 11 for detecting the ambient temperature and light brightness of the device. The temperature sensor and the light sensor 11 can detect the environment of the device at regular intervals, trigger positioning actions, and regularly measure the ambient temperature and light brightness, which can be used in cold chain transportation and express delivery industries. An NTC thermistor 13 is used in conjunction with a circuit to sense the external ambient temperature. The temperature data can be uploaded to the server, and can also be configured with an APP to realize a specific temperature trigger positioning function, etc. The light sensor 11 is used to sense the brightness of the external ambient light, and can be configured with an APP to realize a specific brightness trigger positioning function, etc.

[0051] Furthermore, the positioning device also includes a buzzer, which is used to indicate the device status, call for help or search through prompt sounds of different tones. The positioning device has a built-in buzzer device, which can generate prompt sounds of different tones in conjunction with software control, and is used to indicate the current device status in conjunction with the LED indicator 12, SOS for help or sending a ringing command through the server to find the lost device and other functions. The buzzer driver chip 14 is used to generate a driving voltage higher than the power supply voltage, and the regular frequency signal provided by the MCU is boosted to a higher voltage to drive the buzzer to emit a prompt sound. The buzzer is fixed in the housing.

[0052] In order to take into account both waterproof performance and charging convenience, a magnetic charging method is adopted. The device can be easily charged using the charging cable provided, and the device is sealed to improve waterproof performance. It can be used in outdoor environments and even in some underwater scenes, expanding the use scenarios of the device. The charging chip 4 of the device of this embodiment is used to receive external power and charge the battery. It also has a charging protection function. Charging will be prohibited when the ambient temperature exceeds the allowable charging temperature range. The external charging power interface 5 is connected to the spring pin on the shell structure, and the magnetic charging cable connects the external power supply to the charging chip 4 through the spring pin through this interface.

[0053] In addition, the device of this embodiment is further provided with a WiFi antenna 6 for receiving WiFi signals, a BLE antenna 7 for communicating with a mobile phone APP via BLE, a LoRa antenna 8 for LoRa communication, and a GNSS antenna 9 for receiving GNSS signals.

[0054] Example 2

[0055] The difference between Example 2 and Example 1 is that the above-mentioned version A is adopted, and the low-power GNSS positioning chip 3 of Dafa Technology is adopted. After the GNSS positioning chip 3 receives satellite information through the antenna, the longitude and latitude information is locally calculated. That is, the positioning module of Example 2 adopts a special positioning module-GNSS positioning chip 3. The long-distance communication module is a LoRaWAN communication module. After the longitude and latitude information is locally calculated, the longitude and latitude information is transmitted to the server through the LoRaWAN network.

[0056] In some embodiments, the positioning device further includes an offline storage module, which is used to store the positioning information of the positioning device inside the device when the positioning device is not within the coverage of the long-distance communication module, and upload the positioning information stored in the offline storage module to the server through the long-distance communication module when the device re-enters the coverage of the long-distance communication module. If the device is temporarily out of the coverage of the LoRaWAN network, the positioning information can be stored inside the device and uploaded to the background after the device is back online.
