UWB-based short-distance information publishing and receiving system

Abstract

The invention discloses a close-range information publishing and receiving system based on UWB. The close-range information publishing and receiving system comprises an information sending module and an information receiving module. The information sending module comprises an upper PC, a PPM modulation circuit, a pulse generation circuit, a square wave signal source, a drive generation circuit and a UWB transmitting antenna, wherein the output end of the upper PC is connected with the first input end of the PPM modulation circuit, the input end of the pulse generation circuit is connected with the output end of the square wave signal source, the output end of the pulse generation circuit is connected with the second input end of the PPM modulation circuit, the output end of the PPM modulation circuit is connected with the input end of the drive generation circuit, and the output end of the drive generation circuit is connected with the input end of the UWB transmitting antenna. The information receiving module comprises a UWB receiving antenna, a PPM demodulation circuit and an intelligent terminal, wherein the output end of the UWB receiving antenna is connected with the input end of the PPM demodulation circuit, and the output end of the PPM demodulation circuit is connected with the input end of the intelligent terminal. The close-range information publishing and receiving system has the advantages that information is abundant, the publishing range is wide, and obtaining time is short.

Description

technical field [0001] The invention relates to an information publishing and receiving technology, in particular to a UWB-based short-distance information publishing and receiving system. Background technique [0002] The existing short-distance information release system is very popular in our daily life. Such as railway stations and subway stations, etc., for passengers, it is necessary to inquire about some information, usually through the electronic display screen, to consult at the manual desk to obtain the information we want to know. Places such as stores, hotels or restaurants, in order to promote their own products or preferential activities, merchants in these places generally inform consumers in the place by posting advertisement posters and sending leaflets. For example, in a certain area, in order to announce certain events, the government generally adopts television and newspapers to inform the masses in the area. For example, in museums, cultural attraction...

AI Technical Summary

Problems solved by technology

[0003] These existing broadcast information dissemination methods have some disadvantages: the information displayed on the display screen is limited, workers need to wait in line for consultation, time-consuming, and the leaflets sent are polluted by paper; the paper distributed to passers-by is limited, so the scope of information dissemination is narrow, and the information disseminated by TV and newspapers is limited. The information is not timely, manual explanations have high requirements for the instructors, and the knowledge of the explanations may not be comprehensive, etc.
