The VDU 1506 is a safety helmet type UWB positioning tag that is used by screws or 3M glue.VDU1506 has built-in high-gain PA and LNA. It is a transceiver enhanced uwb positioning tag and uwb ranging tag that supports TWR ranging. The main control chip adopts Nordic nRF52832 to realize low-power standby, and the transceiver control of positioning packets. The radio frequency chip adopts DW1000 to send or receive TDOA/TWR data packets of UWB. VDU1506 can realize high-precision ranging or positioning of wearing personnel under the analysis of uwb base station.

The uwb Tag VDU1506 integrates an acceleration speed sensor inside. Intelligently switch the positioning frequency when people are moving and stationary to achieve lower power consumption. This uwb label is also equipped with an SOS button, which can realize the emergency call function. It is used for safety monitoring occasions, such as personnel positioning and monitoring in factories, mining areas and other places. The uwb label VDU1506 shell adopts ultrasonic lamination technology to achieve IP66 waterproof design. And it is equipped with a white buckle, which can be locked with the main body of the uwb label, which is convenient for personnel to wear.

In addition, there is a motor inside the tag, which can be used with the electronic fence on the uwb base station to realize the safety warning function of approaching/entering a specific area, the social distance warning function of personnel, and it can also be used to receive the emergency evacuation information sent by the base station to realize smart construction sites and factory workers Location security monitoring, etc.
