Industrial field communication system and method based on uwb technology

Abstract

The invention discloses an industrial field communication system and method based on UWB technology. The system includes an industrial PDA, a UWB back clip, an instant messaging APP, a UWB base station and a background data forwarding system. Based on the existing industrial PDA, the present invention adds a UWB back clip, deploys a UWB base station on the industrial site, uses the mature functional modules of the industrial PDA for recording and voice playback, uses the side buttons of the industrial PDA as instant intercom buttons, and develops corresponding dedicated APK application, after setting the default intercom object and group, the user can realize the clear and reliable instant voice intercom function after pressing the intercom button. The coverage radius of the UWB base station can reach more than 300 meters. Enough to cover general industrial site workshops.

Description

technical field [0001] The invention belongs to the technical field of voice communication, in particular to an industrial field communication system and method based on UWB technology. Background technique [0002] With the rapid development of the integrated circuit industry and communication technology and the continuous upgrading and improvement of communication interface protocol specifications, communication technology has made great progress. From the past wired phone to wireless cellular phone, and then to the later data and voice communication, it has been used in various mobile phones. Terminals have been widely popularized, which has brought great convenience to the people's daily life and travel, especially in recent years, instant voice communication, such as: WeChat voice, QQ voice and other communication methods have greatly shortened the communication between people Distance avoids the communication barriers brought about by time and space. [0003] However,...

Problems solved by technology

[0003] However, because its communication technology usually relies on the basic communication network of the operator, the communication effect is relatively good when the network signal is good, but in some special applications, such as industrial sites with complex electromagnetic environments and remote urban areas, The base station covers an unstable area, and the communication signal becomes very poor. The instant messaging effect based on this is also stretched, and it is difficult to realize the real-time and clear voice communication function; in addition, because the current commercial real-time data voice communication is based on the public network frequency band , and various data acquisition and transmission equipment will be deployed on the industrial site, and they basically use the public network communication frequency band, which is easy to interfere with real-time data voice communication; secondly, some special departments in the industrial site are concerned about communication reliability, The confidentiality requirements are very high, which greatly limits the application scope of civil data and voice communication technology
