Problems solved by technology

The above general limitations have also brought a lot of trouble to the promotion and use of walkie-talkies and daily maintenance.
The reason for the above-mentioned problems is mainly that the RF frequencies between the walkie-talkies with general limitations are inconsistent, and the sub-audio frequency is inconsistent.
[0003] In addition, the existing professional channel walkie-talkies generally do not have a display screen, cannot display frequency information, and cannot directly understand the frequency information of the other party's walkie-talkie and make corresponding settings, resulting in the inability to communicate with most walkie-talkies

Embodiment Construction

[0017] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0018] Such as figure 1 As shown, the present invention provides a walkie-talkie, including a walkie-talkie body, the walkie-talkie body has a shell, and an MCU controller 1, a baseband processor 2, a high frequency divider 3, a MIC microphone 4 and a loudspeaker integrated in the shell Speaker 5. The walkie-talkie body receives and sends signals through the antenna. The MCU controller 1 is bidirectionally connected to the baseband processor 2 and the high-frequency divider 3 respectively, and the antenna is connected to the input end of the baseband processor through a low-pass filter, a TX / RX switching module and a high-frequency amplification module in turn, and the antenna It is also connected to the input terminal of the high-frequency divider through a low-pass filter. The output end of the MCU control...

Abstract

The invention discloses an interphone. The interphone comprises an interphone body. The interphone body is equipped with a shell, and an MCU controller, a baseband processor, an MIC microphone and a loudspeaker which are integrally mounted in the shell. The interphone body also comprises a memory, and an LCD screen for displaying radio frequency information and mute audio information. Bidirectional connection is carried out between the memory and the MCU controller. The LCD screen is connected with the output end of the MCU controller. Compared with a traditional technology, the interphone has the advantages that the interphone is equipped with the LCD screen for directly displaying the radio frequency information and the mute audio information from the interphone. Conditions are provided for normal communication among different interphones. The other interphones can carry out corresponding settings through the radio frequency information and mute audio information, and carry out conversations with the interphone.

Description

technical field [0001] The invention relates to the technical field of walkie-talkies, in particular to a walkie-talkie capable of displaying frequency information. 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. At present, walkie-talkies are widely used in security and other fields. However, walkie-talkies with different brands, models, or communication frequencies cannot be used in common use. Sometimes even walkie-talkies of the same brand cannot be used universally if they are not of the same frequency. In conclusion, there are great common limitations between different walkie-talkies. The problem of the above-mentioned general limitations has also brought a lot of troubles to the popularization and use and daily maintenance of walkie-talkies. The reason for the above-mentioned problems is mainly ...
