Problems solved by technology

[0005] The above-mentioned networking method has the following disadvantages: 1. The tags cannot predict the distribution of surrounding base stations in advance, and adopt a fixed sequence of ranging and positioning, so it is impossible to make a better choice according to the actual situation
2. The number of base stations cannot be increased. When there are many objects in the application scene and there are many occlusions, the UWB coverage of the scene cannot be improved by adding base stations; when the application scene site is large, the UWB coverage area cannot be increased by adding base stations

Embodiment

[0052] See image 3 , a networking method for an ultra-broadband wireless communication indoor positioning system, the ultra-broadband wireless communication indoor positioning system includes a networking base station module, three common base station modules, a mobile tag module and a remote monitoring terminal; according to the horizontal axis t In chronological order, the networked base station module that occupies the broadcast time slice of the zero base station initiates broadcasting, and other modules monitor the signals of the networked base station module to maintain time synchronization; then the one that occupies the broadcast time slice of the first base station - the broadcast time slice of the third base station is common The base station module-No. 3 ordinary base station module broadcasts its own information respectively; broadcast time slice at No. 0 base station-No. 15 base station broadcast time slice. The information of the No. 3 ordinary base station modu...

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 for an ultra-broadband wireless communication indoor positioning system. Background technique [0002] UWB (Ultra-wideBandwidth) ultra-wideband wireless communication is a technology that uses nanosecond pulses with extremely short time intervals for communication without using a carrier. 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 less power. 2. Strong multipath resolution ability: Since the UWB radio transmits a single-cycle pulse and the duty cycle is extremely low, the multipath signal is separable in time, and it is easy to separate the multipath component to eliminate interference. 3. High positioning accuracy: Ultra-wideband has strong penetrating ability....
