Abstract

The invention discloses a networking method for an ultra-wideband wireless communication indoor positioning system. A time slice period is initiated by a networking base station module: a scheduling of the time slice period, the time increases from left to right, 16 base station broadcast time slices are reserved, zero base station broadcast time slice-15th base station broadcast time slice, respectively; one network service time slice and 10 tag ranging time slices are number zero tag ranging time slice-number nine tag ranging time slice, respectively; and one data communication time slice. In the method in the invention, the time slice method is adopted to realize time-sharing operation of different functions, thereby greatly reducing the communication conflict problem of multiple modules in an Ultra-Wideband (UWB) local area network; all the modules in the application scenario are connected into the unified UWB local area network, interconnection and mutual understanding are achieved between the modules in the network, and interfaces such as WiFi and Ethernet are provided to the outside, thereby realizing a remote management function of the UWB local area network.

Description

Technical field [0001] The invention relates to the technical field of wireless communication, in particular to a networking method of an ultra-wideband wireless communication indoor positioning system. Background technique [0002] UWB (Ultra-wideBandwidth) ultra-wideband wireless communication is a technology that does not use a carrier and uses nanosecond pulses with very short time intervals for communication. Compared with communication technologies such as WiFi and Bluetooth, UWB has the following advantages: [0003] 1. Low power consumption: use intermittent pulses to send data, the pulse duration is short, and the system consumes low power. 2. Strong multipath resolution capability: Since UWB radio transmits a single-period pulse and has a very low duty cycle, multipath signals are separable in time, and it is easy to separate multipath components to eliminate interference. 3. High positioning accuracy: Ultra-wideband has strong penetrating ability. For common indoor plas...
