Introduction to Skylab‘s Outdoor Waterproof UWB Precise Positioning Anchor VDU2503 and it‘s Application Scenarios

Skylab VDU2503 is an outdoor waterproof UWB positioning anchor. This article is a detailed introduction to it.

Technical Principles

Adopting the DW1000 solution: VDU2503 uses the DecawaveDW1000 UWB solution, which provides a foundation for its high-precision positioning. The DW1000 chip has excellent anti-interference ability and precise ranging performance, which can accurately measure the flight time of UWB signals in complex outdoor environments, thereby achieving accurate position calculation of positioning tags.

TDOA positioning algorithm: The software uses TDOA (Time Difference of Arrival) indoor positioning algorithm to determine the location of the positioning tag by measuring the time difference between UWB signals arriving at different anchor. This algorithm has high positioning accuracy and stability, and can achieve centimeter level positioning accuracy in various indoor and outdoor scenarios. When used in conjunction with UWB positioning tags, the highest positioning accuracy can reach 10 centimeters, with an error of about 30 centimeters based on actual positioning scenarios.

Performance Characteristics

Waterproof and dust-proof: It has IP67 waterproof and dust-proof grade, which can effectively prevent dust from entering, and can be soaked for 30 minutes in an environment with a water depth of 1 meter without affecting normal use. It is fully adapted to various outdoor adverse weather conditions, such as rainstorm, sand and dust, to ensure stable operation in a complex outdoor environment.

Coverage range: The anchor coverage range is greater than 50 meters, which can meet the positioning needs of larger areas, reduce the number of anchor deployed in outdoor environments, and lower system costs and complexity.

Data upload and clock synchronization: Supports 100m Ethernet data upload method, which can quickly transmit positioning data to the server for processing and analysis. At the same time, UWB wireless synchronization is used for anchor clock synchronization, without the need for additional synchronization cables, simplifying the system deployment process and improving the reliability and flexibility of the system.

Physical Characteristics

Power supply method: POE (Power over Ethernet) power supply method is adopted, which only requires one Ethernet cable to achieve data transmission and device power supply simultaneously, greatly reducing customer installation time and wiring difficulty, especially suitable for outdoor environments where it is inconvenient to lay power lines separately.

Equipped with fixed brackets: The anchor is equipped with fixed brackets, which facilitate the fixation of the anchor on outdoor facilities such as walls and utility poles. And the bracket can also flexibly adjust the positioning angle of the anchor to achieve the best positioning effect according to the actual environment and positioning requirements.

Application Scenarios

VDU2503 outdoor waterproof UWB positioning anchor can be widely used in the following scenarios:

Personnel and material vehicle positioning in tunnels and mines: In complex underground environments such as tunnels and mines, real-time positioning of personnel and vehicles can be achieved, improving operational safety and management efficiency.

Positioning of personnel in power plants and substations: Ensuring the safety of personnel in power plants, substations, and other places, achieving precise positioning and trajectory tracking of workers, and facilitating timely scheduling and management.

AGV car positioning in industrial sites: helping industrial enterprises achieve precise positioning and navigation of AGV cars, improving production automation level and logistics transportation efficiency.

Prison personnel positioning: Ensure the safety management of the prison premises, real-time access to the location information of inmates, and prevent the occurrence of unexpected events.
