VDU2506 is a UWB positioning anchor that supports TWR two-way ranging. It complies with coal mine safety certification standards and is IP67 waterproof and dustproof. It has the characteristics of full channel ch1-5, standard POE power supply and so on.
VDU2506 anchor supports TWR/TDOA positioning algorithm. It has a positioning accuracy of less than 30 cm and a coverage radius of 400 meters.
SKU620 is a long-distance UWB ranging module covering a range of 500 meters. It is developed based on DW1000 solution, supports IEEE802.15.4-2011 UWB protocol, and integrates nRF52832 main control chip.
SKU620 ranging accuracy is 10cm-30cm, and supports 500m long-distance ranging. SKYLAB provides multiple interfaces, and customers can carry out secondary development of the module.
The helmet UWB positioning tag VDU1506 was developed and launched by SKYLAB. It is developed based on the DW1000 solution and supports up to 1000 meters TWR two-way ranging and positioning
VDU1506 integrates the SOS button, and the staff can alarm with one button when encountering a dangerous situation.
A card UWB positioning label VDU1501 launched by SKYLAB. It integrates DW1000 and nRF52832 chips and supports TDOA/TWR positioning algorithms.
VDU1501 supports UWB positioning and ranging applications with a positioning accuracy of 10-30 cm. It comes with a lanyard, has an SOS distress button, and is IP67 waterproof.
In order to achieve the best positioning effect, the following items should be paid attention to when installing the base station:
(1)Accurate calibration requires at least 4 labels to be installed, and the area enclosed by the labels is best for calibration.
(2)All labels should be at least 25 cm away from the wall. Do not block the antenna around the label. If there is a wall surrounding it, move it out as far as possible, and try to stay away from steel products.
(3) The label is placed on a horizontal plane, and there is no obstruction between the label and the base station.
(4)The plane coordinate error of label placement cannot exceed 20 cm.
(5) The positioning accuracy of the device in the three-dimensional interval enclosed by the label will be relatively high.
(1)Install 4 uwb labels on the top four corners of the positioning area.
(2)UWB anchors can be positioned in the three-dimensional space area enclosed by four uwb tags.
(3)The spacing between UWB tags is between 3 meters and 30 meters.
(1)Open the software
(2)Connect the device
(3)Configure the ID of the Tag tag
(4)Start coordinate conversion
(5)Positioning effect demonstration
