The railway station is a crowded place. Through the Huaxing intelligent control UWBLOC positioning technology, the real-time accurate positioning of the staff can be realized. The management personnel can know the real-time location distribution of the relevant staff through the management platform at a glance, facilitating unified scheduling and work management, and improving Management level and efficiency. The following figure shows the positioning effect of a train station personnel.
UWBLOC positioning technology is a wireless pulse communication technology. By wearing a pulse transmitting beacon, a pulse receiving device is installed in the railway station hall to realize the positioning management of the target management object. The technology can realize accurate positioning of 30 cm precision in real time. The original definition of UWB is from the pulse communication technology that emerged in the 1960s, also known as Impulse Radio technology. Unlike carrier modulation techniques, which are widely used in today's communication systems, this technique communicates directly with baseband pulses that have steep rising and falling edges, so it is also known as baseband transmission or carrierless. The pulse length of pulsed UWB technology is usually on the order of sub-nanoseconds, and the signal bandwidth is often several gigahertz, which is much larger than the bandwidth of any existing wireless communication technology, so it was eventually called super by the US Department of Defense in 1989. Broadband technology.
The positioning system architecture of Huaxing Zhikong Railway Station personnel is shown in the figure below. The UWBLOC base station selects the wireless transmission type, and only needs to supply the equipment through the power supply. The base station and the positioning engine server transmit wireless data.
