In the era of the Internet of Things, most applications are more or less associated with location services, especially for mobile objects, the positioning requirements are more obvious, so positioning technology has received extensive attention . Against this background, a large number of positioning technologies have also emerged. The more common positioning technologies include GPS, Beidou and other satellite positioning technologies, WiFi/Bluetooth/RFID/UWB small-range positioning technologies, and base station positioning and positioning technologies.
The application scenarios of location-based services are almost everywhere, and the most typical ones are personnel asset management and direction-finding navigation applications based on location information, which have broad market potential in practical applications. Let's focus on the typical positioning application scenarios below .
1. Care for the elderly/children and pets
The characteristic of this type of application is that people and pets have autonomous consciousness, and their actions are highly accidental and cannot be predicted in advance, so it is necessary to collect their location information in real time. GNSS and Bluetooth positioning are more suitable for such application scenarios . GNSS positioning solutions are suitable for outdoor environments, while Bluetooth positioning can meet the Bluetooth indoor positioning solutions suitable for layout of Bluetooth gateways such as nursing homes, nurseries, pet trusteeships/pet hospitals, etc.
2. Internet of Vehicles/UAV
At present, satellite positioning has long been the standard configuration of cars, and new concepts such as drones and autonomous driving also require very accurate location information to be realized. Cars are the most mature application of positioning technology. In recent years, the positioning of the Internet of Vehicles The demand has extended from outdoors to indoors. For example, when entering an underground parking lot, it is necessary to switch between indoor and outdoor positioning scenarios. Therefore, the combination of high-precision GNSS and Bluetooth indoor positioning solutions is more suitable for such application scenarios . For Internet of Vehicles/UAVs with high precision requirements, ordinary GNSS modules cannot meet their location service requirements. They need to support RTK, high-precision GNSS outdoor positioning solutions with centimeter-level positioning accuracy, and reception systems such as underground parking lots The complex environment without satellite signals requires a Bluetooth indoor positioning solution with high adaptability to the positioning environment to provide location services.
3. Personnel/asset management
This type of application scenario covers a wide range of content, such as personnel access in factories and laboratories, hospital patient monitoring and medical equipment management, personnel supervision in prisons, etc. Although in general terms, they are all personnel or asset management, but different application scenarios have different specific requirements, and the desired technologies are also different. Bluetooth/UWB positioning is more suitable for such application scenarios . For example, general asset management can be achieved by using RFID/Bluetooth indoor positioning solutions; and many prison guarding scenes with high precision requirements use UWB; Bluetooth is also more suitable for shopping malls or office buildings where precision requirements are not very high.
4. Personnel and equipment management in high-risk environments
Although the scope of such application scenarios is small, due to the particularity of the environment, the demand for positioning technology is relatively strong, such as mines, construction in tunnels, high-temperature environment operations, power inspections, etc. UWB positioning is more suitable for such application scenarios . This is also a scenario where positioning technology is naturally applicable.
5. Shared mobile devices
The sharing economy has risen rapidly in recent years. For sharing platforms, the core is to manage their devices in real time in order to realize commercial value, including shared bicycles and shared cars. For mobile shared equipment, positioning management is very important, so GNSS and base station positioning are more suitable for the management of large-scale mobile shared equipment .
