Embodiment 1

[0025] see figure 1 , in the embodiment of the present invention: a walkie-talkie system, including an MCU control module for controlling the coordinated work among various modules, a short message communication module for collecting and sending position information and short message information, and a short message communication module for collecting Beidou positioning module for location information, baseband processing module for data processing core, CODEC module for digital-to-analog and analog-to-digital conversion of audio signals, radio frequency transceiver module for receiving and sending radio frequency signals of walkie-talkies, and frequency configuration for walkie-talkies Frequency writing module, power supply module for powering the whole machine, buttons, LCD display, speaker, microphone; short message communication module, Beidou positioning module and baseband processing module are all bidirectionally connected to the MCU control module, and the MCU control m...

Embodiment 2

[0031] see figure 2 , Based on the description of the first embodiment above: the present invention provides a method for using the walkie-talkie system, comprising the following steps:

[0032] Step 1: When sending a signal, the sound is transmitted from the microphone, and the microphone converts the voice signal into an electrical signal through the MCU control module, and the MCU control module sends the electrical signal to the baseband processing module;

[0033] Step 2: The baseband processing module compiles the received electrical signal into a baseband code for transmission, and performs digital-to-analog conversion through the CODEC module, that is, converts the digital baseband code into an analog baseband code;

[0034] Step 3: The RF transceiver module sends the converted analog baseband code to the other party's walkie-talkie;

[0035] Step 4: When the other party's walkie-talkie receives the signal, the RF transceiver module receives the baseband code from th...

Abstract

The invention discloses an interphone system and a use method thereof. The interphone system comprises an MCU control module, a short message communication module, a Beidou positioning module, a baseband processing module, a CODEC module, a radio-frequency receiving-transmitting module, a frequency writing module, buttons, an LCD (Liquid Crystal Display) screen, a loudspeaker and a microphone, wherein the MCU control module is connected with the other modules, and used for controlling the other modules to work cooperatively. The position information of an interphone can be acquired through theBeidou positioning module, and displayed through the LCD screen, and a user can transmit the position information to a background server in real time, so that an operator of the background server canknow the position distribution of the interphone visually. Meanwhile, the interphone can send short message information through the short message communication module during remote communication, sothat positioning can be realized; the position information of the user can be transmitted; remote communication is realized; and the problems of single function, low communication efficiency and shortcommunication distance existing in a traditional interphone are solved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a walkie-talkie system and a method for using the same. Background technique [0002] The walkie-talkie is a two-way mobile communication tool. It can make calls without any network support, and there is no call charge. It is suitable for relatively fixed and frequent calls. With the continuous development of communication technology, the application fields of walkie-talkies are becoming more and more extensive. They are not only widely used in fire monitoring, flood control command, vehicle dispatching, transportation and other fields, but also began to enter the civilian market. Start using walkie-talkies more and more. [0003] At present, the traditional walkie-talkie can only realize the intercom function, and it is mainly used as a small-scale communication tool between group members to realize short-distance wireless communication. For example, when the walkie-talk...
