Problems solved by technology

[0004] According to the above proposal, there are many closed or semi-closed areas such as mines, basements, crowded and remote venues, etc., which cannot cover the network, resulting in technical problems that make non-face-to-face communication difficult, and provide a file transfer and chat for areas without cellular network signals System and method
The invention is mainly developed by using Wi-Fi technology to realize picture sharing, chatting, and downloading and playing of videos in a relatively large range in places that cannot be covered by wireless cellular networks. It has the advantages of no traffic consumption and wide application , strong practicability, novel form, strong scalability, broad prospects, etc., can solve the problem that people have difficulty in communicating in large places with poor signals, and can use the present invention for real-time communication even when mobile phones cannot be connected. Text communication and real-time file transmission have very good synchronization, so it can be used for real-time communication, emergency contact, data sharing in a wide range, and can be extended to emergency rescue and other scenarios, with strong practicability

Abstract

The invention provides a file transmission and chatting system and method for a cellular-network-free signal area, and the system comprises an implementation unit and a mobile phone unit. The implementation unit comprises an equipment interconnection module, a file sending module, a file receiving module, a storage module, a real-time chatting module, a camera module and a flashlight module basedon a Wi-Fi module. The mobile phone unit is equipped with the mobile phone Wi-Fi module and preinstalled with an Android 4.0 or above operating system; the mobile phone unit is in wireless connectionwith the implementation unit by the mobile phone Wi-Fi module to realize file sending, file receiving and chatting functions. The file transmission and chatting system and method are developed based on the Wi-Fi technology, operations such as picture sharing, chatting and playing under the edge of a video can be carried out in a relatively large range in places which cannot be covered by a wireless cellular network, the method has the advantages of no traffic consumption, wide application range, high practicability, novel form, high expandability, wide prospect and the like, and the problem ofdifficulty in communication of people in large places with poor signals can be solved.

Description

technical field [0001] The present invention relates to the technical field of life and industry, in particular, to a system and method for file transmission and chatting in areas without cellular network signals. Background technique [0002] At present, the mobile cellular network is developing rapidly and has covered more and more areas, and the price has gradually dropped, but there are still many closed or semi-closed areas such as mines, basements, crowded and remote venues, etc., which cannot cover the network, resulting in abnormal Difficulties in face-to-face communication. Based on Wi-Fi direct connection technology, this system designs and implements a file transfer and chat system that does not depend on basic network facilities, and can realize functions such as picture sharing, chatting, and side-by-side broadcasting of videos. [0003] WIFI direct connection technology: Wi-Fi Direct, previously known as Wi-Fi Peer-to-Peer, is a new D2D protocol proposed by th...
