Communication system for realizing analog intercom based on mobile phone terminal, and communication method

Abstract

The invention provides a communication system for realizing analog intercom based on a mobile phone terminal, and a communication method, wherein the communication system comprises an analog intercomcommunication module, a Bluetooth-to-TTL module, an intercom antenna and the mobile phone terminal; the mobile phone terminal comprises a mobile phone Bluetooth module and a built-in modulation and demodulation module; in a voice data transmitting stage of a mobile phone, the mobile phone terminal modulates received voice data to a first radio-frequency signal through the built-in modulation and demodulation module, sends the first radio-frequency signal to the analog intercom communication module through the mobile phone Bluetooth module and the Bluetooth-to-TTL module, generates a second radio-frequency signal after demodulating and modulating the first radio-frequency signal through the analog intercom communication module, and transmits the second radio-frequency signal through the intercom antenna; in a voice data receiving stage of the mobile phone, the intercom antenna receives the second radio-frequency signal, generates the first radio-frequency signal after demodulating and modulating the second radio-frequency signal through the analog intercom communication module, and sends the first radio-frequency signal to the mobile phone terminal through the Bluetooth-to-TTL module and the mobile phone Bluetooth module; and, after the first radio-frequency signal is demodulated through the built-in modulation and demodulation module, voice data is obtained and played.

Description

Technical field [0001] The invention relates to the field of wireless communication, and in particular to a communication system and a communication method based on a mobile phone terminal to realize analog intercom. Background technique [0002] With the rapid development of wireless communication technology, smart phone terminals have become very popular, and they are usually equipped with wireless modules to implement wireless signal transmission and reception. On the other hand, because walkie-talkies are not restricted by the network, they are more and more widely used in modern social life, such as property management, catering services, hotel services, police officers on duty patrols, and disaster relief. Current smart phone terminals generally do not support walkie-talkie applications. Therefore, to ensure normal communication, workers in the above-mentioned fields need to be equipped with walkie-talkies for intercom communication in addition to carrying mobile phones dur...

AI Technical Summary

Problems solved by technology

Current smartphone terminals generally do not support intercom applications. Therefore, in order to ensure normal communication, staff in the above-mentioned fields need to be equipped with intercoms for intercom communication in addition to carrying mobile phones during their duties, which will bring some inconvenience to the staff.
