The technology adopted by huaxing intelligent control UWBLOC positioning system is a positioning technology based on UWB carrier-free communication principle. The UWBLOC technology USES nanosecond to microsecond non-sinusoidal narrow pulse to transmit data. By transmitting extremely low-power signals over a wide spectrum, the UWBLOC can achieve data transmission rates of hundreds of Mbit/s to several Gbit/s over a range of about 100 meters.
UWBLOC technology has strong anti-interference performance, high transmission rate, large system capacity and very small transmission power. The transmission power of the UWBLOC system is very small, and the communication equipment can communicate with the transmission power of less than 1mW. Low transmission power can greatly extend the working time of system power supply. Moreover, the emission power is small, its electromagnetic wave radiation to the human body will be very small. The positioning precision of huaxing intelligent control personnel positioning system can be up to 10cm, millisecond delay real-time display of personnel position.
UWBLOC signal almost does not work in the same frequency of wireless equipment interference, UWBLOC signal has a strong ability to penetrate, can be in indoor and underground space such as tunnels, pipe gallery, accurate positioning, and GPS positioning system can only work in the visible range of GPS positioning satellites; Unlike the absolute geographic position provided by GPS, the UWBLOC pulse-positioner can give a relative position with a positioning accuracy of up to centimetres. In addition, the UWBLOC wireless positioner is cheaper.
Need UWBLOC installed in the base station in the factory, equipped with UWBLOC labels, tags are active beacon, label according to certain frequency signal pulse, the base station is responsible for receiving a pulse signal, through the pulse time of arrival in the base station can compute the distance of labels and base station, in the final can get through the complexity of signal processing personnel real-time position; It should be noted that the antenna of the signal base station should be far away from the metal shielding object, because the metal object will reflect the pulse signal and the base station will not be able to receive the signal pulse sent by the tag, which will cause the signal loss, resulting in positioning failure. When installing base stations, it is necessary to determine the X,Y and Z coordinates of each base station (this coordinate is determined by the customized rectangular coordinate system), so as to calculate the accurate position of personnel in real time.
The base station is connected with the POE switch through the network cable (POE switch can realize data communication and power supply of the base station), and the POE switch transmits the data to the positioning engine server, which calculates the real-time position of the personnel wearing the beacon through the installed positioning software and complex algorithm. UWBLOC pulse-radio communication is used between the beacon and the base station, and the personnel can wear the beacon on the hand or fix it on the hard hat.
