ir-uwb positioning and ranging module indoor personnel high precision positioning

2023-02-01 405

How does ir-uwb positioning and ranging module achieve high precision positioning of personnel in indoor positioning? Among many indoor positioning technologies, UWB is currently a commercial positioning system with high precision, which realizes the realization of personnel. Material and vehicle real-time positioning and positioning capacity, accuracy up to 10cm. However, the positioning accuracy of RFID, ibeacon, GPS and other positioning technologies is limited. Even if the positioning accuracy of UWB is the same, the complexity and cost of the system are too high. So, how does UWB achieve high precision positioning?

How does ir-uwb positioning and ranging module realize accurate positioning of indoor positioning technology? ir-uwb positioning and ranging module adopts broadband narrow pulse communication technology (high time resolution, reduce positioning error). Multi-source data integration (effectively improve the anti-interference ability of the positioning system) and time series signal processing technology (extract the first path signal in the strong multi-path complex environment) to achieve accurate positioning of the positioning target.


What kind of indoor positioning technology does ir-uwb positioning and ranging module adopt? The ir-uwb positioning and ranging module system adopts TOA and TOATDOA to ensure the high-precision positioning effect, while the two positioning methods greatly reduce the power consumption of positioning tags. These two localization methods belong to ranging localization algorithm.


Through the time difference of signal arrival, the ultra wiband system consists of generating transmission, receiving and radio systems to process extremely narrow pulse signals through hyperbolic cross positioning. The positioning system of ir-uwb ranging module includes UWB receiver, UWB reference tag and active UWB tag. The UWB receiver receives the UWB signal sent by the label in the positioning process, and obtains the signal of effective information by filtering various noise interference in the electromagnetic wave transmission process, and then carries out the ranging and positioning calculation and analysis through the central processing unit.


Because different industries have different requirements on positioning system hardware and software functions, different solutions are proposed for various industries to help enterprises achieve personnel security management.


What equipment does UWB need to achieve indoor positioning technology?

1. Locate labels

2. Locate the base station


What industry problems does ir-uwb positioning and ranging module solve?

1. Real-time personnel positioning management: visually inspect the location distribution of personnel, materials and vehicles, which is more effective in work scheduling;

2. Tracking of moving track: you can specify the real-time moving position of any person and query the moving track by playback;

3. Video high-speed linkage: Combining the positioning system of ir-uwb positioning and ranging module with monitoring equipment, video linkage function can also be realized;

4. Intelligent inspection: Enterprises can customize inspection points and inspection routes according to inspection requirements of production equipment.

5. Electronic fence: the function of electronic fence ensures the production safety of special areas, enables the normal and smooth operation of enterprises, and improves the production efficiency and management level of enterprises;

6. Long-term static warning: If the static time exceeds the set time, the system will send an early warning message to remind the manager of timely rescue;

7.SOS alarm: in case of an accident, the personnel can immediately press the button to call for help, and the background can carry out rescue according to the distress position to reduce accident losses and casualties.


With the continuous maturity and development of indoor positioning technology, the market demand is increasing, ir-uwb positioning ranging module it will also usher in rapid development. It is believed that positioning technology will soon be fully commercialized and precise positioning systems will be widely used.
