Description

A locator that can acquire motion status and data Technical Field

[0001] This invention relates to the field of locator technology, specifically to a locator capable of acquiring motion status and data. Background Technology

[0002] Currently available wearable positioning devices only locate the wearer to prevent loss, offering limited functionality. For example, Chinese Utility Model Patent CN202121291364.1 discloses a wearable positioning tracker, including a locator with ring-shaped fasteners on both sides. The locator contains a circuit board, which includes at least a Bluetooth module, a GPS module, a wireless network module, a charging module, a storage module, and a main control MCU. All these modules are electrically connected to the main control MCU. This invention achieves positioning via a GPS module and reports the location information and movement trajectory to the user device via an LTE or Wi-Fi network through the wireless network module. This patent solves the technical problem of how to achieve wearable positioning and tracking.

[0003] Currently, users of existing wearable positioning devices typically install cameras in their homes to achieve visual monitoring and interaction with the wearer. However, once the wearer leaves the home or the camera's field of vision, the user will be unable to perform visual monitoring. Therefore, there is an urgent need to develop a positioning device that can obtain motion status and data to meet practical needs. Summary of the Invention

[0004] The purpose of this invention is to provide a locator that can obtain motion status and data, and to form autonomous data acquisition by combining the gyroscope and accelerometer in the locator, and to realize visual monitoring of the wearer by combining it with an APP including a digital clone display module and a digital clone database.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A locator capable of acquiring motion status and data includes a housing and a locator main unit. A mounting cavity is formed within the housing, and the locator main unit is mounted within the mounting cavity. The locator main unit includes a battery, a PCBA (Printed Circuit Board Assembly) electronic circuit board, and a chip. The battery is electrically connected to the PCBA electronic circuit board, and the chip is fixed to the PCBA electronic circuit board.

[0007] The PCBA electronic circuit integrated board is also equipped with a gyroscope and an accelerometer. The gyroscope is used to measure the displacement, velocity, speed, center of gravity, gravity and spatial coordinates of the wearer in relative space. The accelerometer is used to measure the acceleration of the wearer. Both the gyroscope and the accelerometer are electrically connected to the chip through the PCBA electronic circuit integrated board. The gyroscope and the accelerometer feed back the measured displacement, velocity, speed and acceleration to the chip.

[0008] The locator is equipped with a matching wearable device and an APP. The APP includes a digital clone display module and a digital clone database. Displacement, velocity, rate and acceleration data provided by the gyroscope and accelerometer are fused and matched with the data in the digital clone database through the MCU algorithm system, and can be displayed in the user's APP to reflect the movement status of the wearable device.

[0009] As a further embodiment of the above description, the shell is provided with a hole through which a wearable device passes. The wearable device is fixed around and fixed to the corresponding part of the wearer. The gyroscope inside the shell can obtain the displacement, velocity, and speed of the corresponding part of the wearer. The posture of the wearer can be determined by the data in the digital clone database. The accelerometer inside the shell can follow the movement of the wearer and obtain the displacement acceleration of the wearer. A 3D digital clone of the wearer is constructed through the digital clone display module in the APP.

[0010] As a further solution, the APP also includes a wearable positioning function, which consists of multiple positioning technologies, including Global Positioning System (GPS), BeiDou Navigation Satellite System (BDS), and Wi-Fi location analysis, to locate the wearer.

[0011] As a further solution, the APP also includes location data transmission and parsing capabilities, including GPS, BeiDou, and GLONASS data parsing. By parsing GPGGA and GPRMC commands, we can obtain all the data content we need, including but not limited to latitude and longitude, time, satellite search status, number of satellites, altitude, and speed.

[0012] As a further solution, the app also includes an emergency tracking function, which records the historical trajectory of the wearer's activities to enable location tracking and facilitate quick retrieval of the wearer.

[0013] As a further solution, the app also includes a sports management function, which records the wearer's activity history and data.

[0014] As a further solution, the APP also includes a fence warning function. Users can set a safe activity area for the wearer through this fence warning function. If the wearer leaves the safe activity area, the APP will immediately issue an alarm reminder.

[0015] As a further solution, the APP also includes an electronic traction function. Users can set a safe distance between the wearer and the terminal device where the APP is located through this electronic traction function. When the distance between the wearer and the terminal device where the APP is located exceeds the safe distance, the APP will immediately issue an alarm.

[0016] As a further embodiment of the above description, the PCBA electronic circuit integrated board is also electrically connected to an external power source. Several conductive posts are fixedly connected to the PCBA electronic circuit integrated board, and corresponding conductive post seats are provided within the mounting cavity. A charging interface is provided on the housing. Each conductive post passes through the conductive post seat, and the conductive post seat is housed within the charging interface. The external power source is inserted into the charging interface and electrically connects to the conductive post within the conductive post seat, thereby supplying power to the PCBA electronic circuit integrated board. A first magnetic element is provided around the conductive post seat, and a second magnetic element is also provided on the corresponding external power charging data line. The first and second magnetic elements are magnetically attracted to each other, thus facilitating the connection of the external power charging data line to the charging interface.

[0017] As a further solution, the housing is also equipped with an RGB light, which is electrically connected to the PCBA electronic circuit integrated board; the RGB light changes color to indicate that the wearable smart locator is in different states.

[0018] The beneficial effects of this invention are as follows:

[0019] The locator of this application, which can obtain motion status and data, internally uses gyroscopes and accelerometers to feed back the measured displacement, velocity, rate, and acceleration to the chip. At the same time, the digital clone database can compare and judge the wearer's motion posture and activity data based on the real-time changes in motion data such as displacement, velocity, rate, and acceleration. Thus, the digital clone display module in the APP forms a real-time 3D motion model and animation of the wearer, realizing all-round visual monitoring of the wearer without the assistance of external devices.

[0025] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0026] Please refer to Figures 1-5, which illustrate a specific implementation of a locator capable of acquiring motion status and data. The locator includes a housing 1 and a locator host 2. A mounting cavity 11 is formed within the housing 1, and the locator host 2 is installed within the mounting cavity 11. The locator host 2 includes a lithium-ion battery 3, a PCBA electronic circuit integrated board 4, and a chip 5. The lithium-ion battery 3 is electrically connected to the PCBA electronic circuit integrated board 4, and the chip 5 is fixed to the PCBA electronic circuit integrated board 4.

[0027] The PCBA electronic circuit integrated board 4 is also equipped with a gyroscope and an accelerometer. The gyroscope is used to measure the displacement, velocity, speed, center of gravity, gravity and spatial coordinates of the wearer in relative space. The accelerometer is used to measure the acceleration of the wearer. Both the gyroscope and the accelerometer are electrically connected to the chip 5 through the PCBA electronic circuit integrated board 4. The gyroscope and the accelerometer will feed back the measured displacement, velocity, speed and acceleration to the chip 5.

[0028] The locator is equipped with a matching wearable device and an APP. The APP includes a digital clone display module and a digital clone database. Displacement, velocity, rate, and acceleration data provided by the gyroscope and accelerometer are fused and matched with the data in the digital clone database through the MCU algorithm system. The motion state of the wearable device can be reflected in the user's APP. The housing 1 has a hole 7 through which a wearable device passes. The wearable device is fixed around the corresponding part of the wearable device. The gyroscope in the housing 1 can obtain the displacement, velocity, and rate of the corresponding part of the wearable device. The posture of the wearable device can be determined by the data in the digital clone database. The accelerometer in the housing 1 can follow the movement of the wearable device and obtain the displacement and acceleration of the wearable device. The digital clone display module in the APP constructs a 3D digital clone of the wearable device.

[0029] Specifically, the locator supports CATM1+NB2 communication, GPS / BeiDou / GLONASS satellite positioning, and trajectory viewing for both motion and stationary states. It features a 6-axis gyroscope inertial navigation capability, ultra-fast data sampling via algorithms, and long-term data storage. In conjunction with the platform, it supports WIFI-assisted positioning and base station-assisted positioning. It also features fast serial data transmission, motion data capture, and algorithm processing before transmission to the backend. Through artificial intelligence algorithms, other auxiliary algorithms, and scanning imaging technology, it automatically generates simulated 3D dynamic images. The locator has a WIFI and Bluetooth SOC as its main controller, communicating via UART and AT commands with the integrated GNSS positioning cellular module to obtain IMEI, ICCID, and signal strength, and to determine the longitude and latitude of the ground. The main controller communicates with the six-axis sensor via I2C / SPI, performing filtering, fusion, and other algorithmic processing. The computing box analyzes the motion attitude data to calculate the number of steps, distance, and spatial coordinates. The built-in WIFI in the main controller assists in positioning and simultaneously uploads battery voltage and charging detection data collected by the AD converter to the platform.

[0030] The app also includes a wearable positioning function, which consists of multiple positioning technologies, including Global Positioning System (GPS), BeiDou Navigation Satellite System (BDS), and Wi-Fi location analysis, to locate the wearer.

[0031] As a further solution, the APP also includes satellite positioning data transmission and analysis capabilities, including GPS, BeiDou, and GLONASS data analysis capabilities. These capabilities are used to analyze GPGGA and GPRMC commands to obtain all the data we need, including but not limited to latitude and longitude, time, satellite search status, number of satellites, altitude, and speed.

[0032] Further plans include the app also featuring emergency tracking, motion management, geofencing alerts, and electronic traction.

[0033] The emergency tracking function records the wearer's historical activity trajectory, enabling emergency tracking and location services to facilitate quick retrieval of the wearer. The motion management function records the wearer's activity history and data. Users can set a safe activity area for the wearer through the fence warning function. If the wearer leaves the safe activity area, the APP will immediately issue an alarm. Users can set a safe distance between the wearer and the terminal device where the APP is located through the electronic traction function. If the distance between the wearer and the terminal device where the APP is located exceeds the safe distance, the APP will immediately issue an alarm.

[0034] The aforementioned emergency tracking, motion management, fence warning, and electronic traction functions are all based on multi-positioning technology. After the GPS receiver is powered on, it automatically sends formatted data packets through the serial port to calculate various geographic location information, including location data, UTC time (hour, minute, second format), positioning status, valid positioning, invalid positioning, latitude, longitude, ground speed, ground heading (with true north as the reference, and the leading zeros will also be transmitted), magnetic declination, magnetic declination direction, mode indication, autonomous positioning, differential, estimation, and invalid data. Simultaneously, the built-in Wi-Fi can assist in positioning. Wi-Fi-assisted positioning is achieved by scanning the MAC addresses of nearby Wi-Fi networks. The device uploads the Wi-Fi MAC address to the server, which then deciphers the latitude and longitude corresponding to that Wi-Fi MAC address. The data comes from third-party platforms or is collected by the program itself.

[0035] As a further embodiment of the above description, the PCBA electronic circuit integrated board 4 is also electrically connected to an external power source. Several conductive posts 8 are fixedly connected to the PCBA electronic circuit integrated board 4, and a corresponding conductive post seat 9 is provided within the mounting cavity 11. A charging interface is provided on the housing 1. Each conductive post 8 passes through the conductive post seat 9, and the conductive post seat 9 is housed within the charging interface. The external power source is inserted into the charging interface and electrically connects to the conductive post 8 within the conductive post seat 9, thereby supplying power to the PCBA electronic circuit integrated board 4. A first magnetic element 6 is provided around the conductive post seat 9, and a second magnetic element is also provided on the corresponding external power charging data line. The first magnetic element 6 and the second magnetic element are magnetically attracted to each other, thus facilitating the connection of the external power charging data line to the charging interface.

[0036] As a further solution, the housing 1 is also provided with an RGB light 10, which is electrically connected to the PCBA electronic circuit integrated board 4; the RGB light 10 indicates the different states of the wearable smart locator through light changes.

[0037] The task execution process of a locator that can acquire motion state and data:

[0038] The system features a dual-system and background system design. The application operates in an infinite loop, with MCU1 and MCU2 working in coordination during normal operation. An embedded operating system enhances system reliability and improves application security. The embedded design divides the entire program into numerous independent tasks. Even if one task encounters a problem, it won't affect the operation of other tasks. This improves system reliability, simplifies program debugging and execution, and makes the system more convenient and faster. The SDK provides a series of APIs and libraries to help users easily utilize navigation resources. This locator also allows for easier system self-learning and intelligent in-depth application, as detailed in Figures 4-5.

[0039] The GPS chip acquires the wearable device's location information. MCU1 reads the data using a UART or SPI interface, parses the data to extract latitude and longitude coordinates, and sends the location information to the cloud server. This task manages the power consumption of the wearable positioning device. The power IC's management task mainly manages the power supply of the wearable positioning device, including battery charging, power detection, and low battery protection. MCU1 collects processed data from the Flash memory, packages it (packaging rules are detailed in the communication protocol), and uploads the data to the cloud server via the Cat-M / Nb-IOT network according to the MQTT protocol. SPI performs read / write operations, first caching the data in EEPROM before saving it to Flash memory all at once, avoiding frequent Flash erase / write operations and reducing Flash memory lifespan. This task is responsible for updating the firmware of the wearable positioning device via over-the-air (OTA) using the Cat-M or NB network. The implementation process may include configuring the OTA module to download firmware updates from a remote server. It has timer interrupt data upload functionality; serial UART execution of server commands; Bluetooth connectivity and gyroscope data processing capabilities.

[0040] Complete feature demonstration:

[0041] ① Enable Bluetooth and connect to the phone. ② Enable Wi-Fi, obtain the Wi-Fi MAC address, and store it in Flash. ③ Receive and process data from the six-axis gyroscope, using complementary filtering and Kalman filtering algorithms. ④ Detect abnormal situations and issue alarms.

[0042] Functional Logic Technical Description:

[0043] 1. There are two communication methods: narrowband channel and Bluetooth channel;

[0044] 2: To save power consumption and data usage, the interaction between the locator and the platform (various telecommunications platforms) is a request-response mode. The request reports the relevant data all at once, and the response sends the corresponding configuration.

[0045] 3: The device Bluetooth naming uses the company's custom rule: Dgns + _ + two-digit serial number + _ + the last 3 bytes of the device Bluetooth MAC address, such as Dgns_01_78d0d1 (the Bluetooth MAC address is be:32:55:78:d0:d1);

[0046] 4. The positioning modes are divided into tracking mode, search mode and normal mode. Regardless of the mode, Wi-Fi positioning and satellite positioning will be used. If Wi-Fi positioning fails (at least one location is detected or no location is detected), GPS and other satellite positioning data will be used.

[0047] 5. The search or tracking mode has a maximum duration, which can be set by the platform;

[0048] 6: In normal mode, when using Wi-Fi for location, if the device detects more than 3 identical Wi-Fi networks compared to the last time, the device considers that it does not need to report the location. However, there is a maximum limit to the number of times the location is reported. If this number is exceeded, the location needs to be reported once. This limit can be set by the platform.

[0049] 7: When in search or tracking mode, the locator will automatically light up and flash, indicating that the light is on. Users can turn it off via Bluetooth command.

[0050] 8: Once the device detects that Bluetooth has been connected and communication has occurred, the device does not need to be located or upload data through the narrowband channel; all communication is conducted via Bluetooth.

[0051] 9: The downlink UTC time and user time zone (device converted to user local time) of the APP (Bluetooth) or platform (general) are used. Except for step counting statistics, which need to report the date (user local date), other devices do not need to report the time and time zone.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present invention without departing from the scope of the present invention are within the scope of the present invention.
