Abstract
Description
Technical Field
[0001] This utility model belongs to the field of positioning technology, specifically relating to a locator with altitude information output. Background Technology
[0002] GPS and base station positioning technologies basically meet users' location service needs in outdoor scenarios. However, in indoor scenarios, GNSS signals will attenuate rapidly or even be completely blocked due to the obstruction of buildings, making it impossible to meet the positioning needs in indoor scenarios.
[0003] Currently, most indoor positioning terminals can only perform two-dimensional planar positioning, lacking height data. Even UWB positioning technology, which can perform three-dimensional positioning, has extremely strict requirements during on-site installation and deployment. For example, when UWB obtains the height data of the positioning terminal carried by the user, some base stations need to be installed with a significant height difference along the Z-axis from the base stations on the upper plane to ensure accuracy on the Z-axis. This causes considerable inconvenience to installation and construction, and creates great difficulties for planning and installation. To address these issues, we propose a locator with height information output. Utility Model Content
[0004] The purpose of this invention is to provide a locator with altitude information output, which can solve the problem that existing positioning terminals on the market cannot directly output altitude data, reduce the construction difficulty of indoor three-dimensional positioning, and improve the accuracy of three-dimensional positioning.
[0005] The specific technical solution adopted by this utility model is as follows: A locator with altitude information output includes a locator housing, which is a hollow structure with openings at both ends communicating with the outside. Each end of the locator housing has a mounting cover that matches the opening. The locator housing contains a main control MCU, a temperature sensor, a pressure sensor, and an IMU sensor. The locator housing also contains a fixed main body that matches the main control MCU, temperature sensor, pressure sensor, and IMU sensor. A movable cooling main body is provided on the opposite sidewall of each of the two mounting covers.
[0006] In a preferred embodiment, the fixing body includes a horizontally arranged fixing plate with multiple slots, which are respectively matched with the main control MCU, temperature sensor, air pressure sensor and IMU sensor. Fixing rods are snapped into both ends of the fixing plate, and the opposite ends of the two fixing rods are arranged through the side wall of the locator housing. The two side walls of the locator housing are provided with movable buckles that match the fixing rods.
[0007] In a preferred embodiment, the mobile cooling body includes a mobile plate, on which a cooler is snapped. The output end of the cooler is fixedly connected to a hollow heat dissipation plate. The heat dissipation plate is connected to the side wall of the mobile plate by two symmetrically arranged snap-fit rods. The side wall of the heat dissipation plate is provided with an air outlet that communicates with the outside and is located away from the cooler. A dispersing mesh is snapped into the air outlet.
[0008] In a preferred embodiment, the movable plate is provided with an installation opening that extends through the side wall of the movable plate. The side wall of the mounting cover is provided with a driver, and the output end of the driver is connected to a gear. The gear is a half gear, and both inner walls of the mounting opening are provided with tooth grooves that mesh with the gear.
[0009] In a preferred embodiment, the temperature sensor is connected to the main control MCU to acquire the ambient temperature and transmit the ambient temperature data to the main control MCU. The barometric pressure sensor is connected to the main control MCU to calculate the current altitude value based on the barometric pressure value at the current location and transmit the altitude value to the main control MCU.
[0010] In a preferred embodiment, the IMU sensor is connected to the main control MCU, and a fusion algorithm combining the step frequency and step amplitude method and the time frequency conversion integral method is used to calculate the height of people indoors, and the calculated height-related data is transmitted to the main control MCU.
[0011] The technical effects achieved by this utility model are as follows: When the locator is in operation, its internal main control MCU, temperature sensor, barometric pressure sensor, and IMU sensor are first stably installed using the mounting plate. The mounting plate has slots that match each component; the main control MCU, temperature sensor, barometric pressure sensor, and IMU sensor are embedded into their respective slots. Then, the fixing rods at both ends of the mounting plate engage with the movable latches on the side wall of the locator housing, ensuring the components are securely held within the housing and providing a stable foundation for subsequent data acquisition. Next, each sensor begins data acquisition. The temperature sensor acquires real-time ambient temperature data around the locator and transmits the data to the main control MCU. The barometric pressure sensor detects the air pressure at its location, calculates the current altitude based on the correlation between air pressure and altitude, and simultaneously transmits the altitude value to the main control MCU. The IMU sensor uses a fusion algorithm combining step frequency and stride method with time-frequency conversion integration to calculate the altitude changes of people indoors, obtaining altitude-related data which is then transmitted to the main control MCU. After receiving the three types of data, the main control MCU performs comprehensive processing and fusion calculations to ultimately generate accurate altitude information.
[0012] During data acquisition and processing, the mobile cooling unit initiates cooling based on actual conditions. When the driver on the side wall of the mounting cover operates, it drives the gears of the half-gear structure to rotate. These gears mesh with the toothed grooves on the inner wall of the mounting opening of the mobile plate, thus driving the mobile plate to move within the positioner housing. Once the cooler on the mobile plate is activated, the generated cooling energy is transferred through the hollow heat sink. The cooling energy is then discharged through the air outlets on the side wall of the heat sink, and the distribution mesh evenly distributes the cooling energy inside the positioner housing, cooling components such as the main control MCU. Simultaneously, the movement of the mobile plate allows for more comprehensive cooling coverage inside the housing, ensuring that all components operate at suitable temperatures and guaranteeing the stability of data acquisition and processing. Throughout operation, the mounting covers at both ends of the positioner housing, through their matching design with the openings, protect the internal components, preventing external dust and impurities from entering and affecting component operation. All components work together to achieve the positioning function with high-information output. Attached Figure Description

The locator housing 1 is provided with a main control MCU 3, a temperature sensor 4, a pressure sensor 5, and an IMU sensor 6. The locator housing 1 is also provided with a fixed body that is matched with the main control MCU 3, the temperature sensor 4, the pressure sensor 5, and the IMU sensor 6. The side walls of the two mounting covers 2 on opposite sides are provided with movable cooling bodies.
[0017] The fixing body includes a horizontally arranged fixing plate 7. The fixing plate 7 has multiple slots, which are respectively matched with the main control MCU 3, temperature sensor 4, air pressure sensor 5, and IMU sensor 6. Fixing rods 8 are snapped into both ends of the fixing plate 7. The opposite ends of the two fixing rods 8 are set through the side wall of the positioner housing 1. The two side walls of the positioner housing 1 are provided with movable buckles 9 that match the fixing rods 8.
[0018] The mobile cooling unit includes a mobile plate 10, on which a cooler 11 is snapped. The output end of the cooler 11 is fixedly connected to a hollow heat dissipation plate 12. The heat dissipation plate 12 is connected to the side wall of the mobile plate 10 through two symmetrically arranged snap-fit rods 13. The side wall of the heat dissipation plate 12 is provided with an air outlet that communicates with the outside, and the air outlet is set away from the cooler 11. A dispersion net 14 is snapped into the air outlet.
[0019] The movable plate 10 is provided with an installation opening 15, which extends through the side wall of the movable plate 10. The side wall of the mounting cover 2 is provided with a driver 16, and the output end of the driver 16 is connected to a gear 17. The gear 17 is a half gear, and the inner walls on both sides of the installation opening 15 are provided with tooth grooves that mesh with the gear 17.
[0020] Temperature sensor 4 is connected to the main control MCU3 to acquire the ambient temperature and transmit the ambient temperature data to the main control MCU3. Barometric pressure sensor 5 is connected to the main control MCU3 to calculate the current altitude value based on the air pressure value at the current location and transmit the altitude value to the main control MCU3.
[0021] IMU sensor 6 is connected to the main control MCU3. It uses a fusion algorithm of step frequency and step amplitude method and time frequency conversion integral method to calculate the height of people in the room, and transmits the calculated height-related data to the main control MCU3.
[0022] In this invention, when the positioner is in operation, its internal main control MCU3, temperature sensor 4, air pressure sensor 5, and IMU sensor 6 are first stably installed through the fixing body. The fixing plate 7 of the fixing body is provided with slots that match each component. The main control MCU3, temperature sensor 4, air pressure sensor 5, and IMU sensor 6 are respectively inserted into the corresponding slots. Then, the fixing rods 8 at both ends of the fixing plate 7 are engaged with the movable buckles 9 on the side wall of the positioner housing 1, so that each component is kept stable inside the positioner housing 1, providing a stable foundation for subsequent data acquisition.
[0023] Next, each sensor initiates data acquisition. Temperature sensor 4 acquires real-time ambient temperature data around the locator and transmits the data to the main control MCU3; barometric pressure sensor 5 detects the air pressure at its location, calculates the current altitude based on the correlation between air pressure and altitude, and simultaneously transmits the altitude value to the main control MCU3; IMU sensor 6 uses a fusion algorithm combining stride frequency and stride amplitude methods with time-frequency conversion integration to calculate the altitude changes of people indoors, obtaining altitude-related data which is then transmitted to the main control MCU3. After receiving the three types of data, the main control MCU3 performs comprehensive processing and fusion calculations to ultimately generate accurate altitude information.
[0024] During data acquisition and processing, the mobile cooling unit initiates cooling based on actual conditions. When the driver 16 on the side wall of the mounting cover 2 operates, it drives the gear 17 of the half-gear structure to rotate. The gear 17 meshes with the tooth groove on the inner wall of the mounting opening 15 of the moving plate 10, thereby driving the moving plate 10 to move within the positioner housing 1. After the cooler 11 on the moving plate 10 is activated, the generated cooling energy is transferred through the hollow heat sink 12. The cooling energy is then sent out through the air outlet on the side wall of the heat sink 12, and the distribution net 14 evenly distributes the cooling energy into the interior of the positioner housing 1, cooling components such as the main control MCU 3. Simultaneously, the movement of the moving plate allows the cooling energy to more comprehensively cover the interior of the housing, ensuring that each component operates at a suitable temperature and guaranteeing the stability of data acquisition and processing. Throughout the entire operation, the mounting covers 2 at both ends of the positioner housing 1, through their matching configuration with the openings, protect the internal components, preventing external dust and impurities from entering and affecting component operation. All components work together to achieve the positioning function with high-information output.
