Description

More PTT intercoms

Technical field

The utility model is related to field of communication technology, specially more PTT intercoms.

Background technology

Intercom is a kind of bidirectional mobile communication instrument, in the case where not needing to any network support, it is possible to it converses, There is no telephone expenses generation, suitable for being relatively fixed and the occasion of frequently conversing, intercom there are three categories at present：Analog walkie-talkie, number Word intercom, IP intercoms, wireless tranceiver is the mobile radio communication device used earliest by the mankind, early in twentieth century The '30s begin to be applied, it is the terminal that a kind of wireless point to multi--point that can be used on the move communicates Equipment can make many people while exchange each other, and many people is enable to hear that same person is spoken simultaneously, but can only in synchronization The characteristics of there are one people to talk, this communication mode and different other communication modes：Immediately it links up, get ready to go into action in hundreds, is economical real With, operation cost is low, does not expend cost of the phone call, easy to use, while also have group call through broadcast, system calling, confidential calls etc. Function, in urgent accident is handled, its effect is that other meanss of communication are irreplaceable in commander is scheduled, number Word intercom is compared with traditional analog walkie-talkie, strong antijamming capability, good confidentiality, and channel occupied bandwidth is narrower, transmits number According to ability it is stronger the advantages that, cooperation digital junction and GSM the telephone systems difference of present digital walkie-talkie is little, can send Short message, sends GPS information, and relaying roaming is generally called, group is exhaled, individual calling etc..

The one kind for the intercom that PTT intercoms belong to, but button is operable there are one existing PTT intercoms, it is not square Just user is modified the type of call of intercom, malfunction, it has not been convenient to which the use of user reduces PTT pairs Say the practicability of machine.

Utility model content

(1) the technical issues of solving

In view of the deficiencies of the prior art, the utility model provides more PTT intercoms, has the advantages that operability is flexible, It solves existing PTT intercoms only to be operated there are one button, it has not been convenient to which user carries out more the type of call of intercom Change, the problem of malfunction.

(2) technical solution

To realize the flexible purpose of aforesaid operations, the utility model provides following technical solution：More PTT intercoms, packet PTT key-press modules are included, the PTT key-press modules include PTT buttons one, PTT buttons two and PTT buttons three, the PTT buttons one Output terminal be electrically connected with MCU modules, the output terminal of the PTT buttons two and PTT buttons three with the input terminal of MCU module Electrical connection, the output terminal of the MCU module are electrically connected with radio-frequency module.

Preferably, the PTT key-press modules have multiple PTT buttons, and each PTT buttons are programmable, independent control.

Preferably, the MCU module sets corresponding type of call to each PTT buttons.

Preferably, the radio-frequency module includes receiving and transmitting signal module and speech processing module.

(3) advantageous effect

Compared with prior art, the utility model provides more PTT intercoms, has following advantageous effect：

1st, more PTT intercoms, pass through PTT key-press modules, PTT buttons one, PTT buttons two, PTT buttons three, MCU module With being used cooperatively for radio-frequency module, solve existing PTT intercoms and only operated there are one button, it has not been convenient to user couple The problem of type of call of intercom is modified, malfunction has the advantages that operability is flexible, multiple PTT is set to press The type of calls such as key, respectively intercom generally call, group is exhaled, individual calling provide calling shortcut key, convenient in different type of calls Realization is switched fast, the use for the person of being convenient to use, and improves the practicability of PTT intercoms.

2nd, more PTT intercoms, by the setting of PTT key-press modules, PTT buttons one, PTT buttons two, PTT buttons three, User can be modified the type of intercom call by each button, and operability is flexibly, user-friendly, By the setting of MCU module, each keystroke interface level change is detected, and then changes the type of call said machine, is led to The setting of radio-frequency module is crossed, plays the role of receiving and transmitting signal and speech processes.

Description of the drawings

Fig. 1 is the utility model software and hardware functional block diagram.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

Referring to Fig. 1, more PTT intercoms, including PTT key-press modules, PTT key-press modules include PTT buttons one, PTT is pressed Key two and PTT buttons three, PTT key-press modules have multiple PTT buttons, and each PTT buttons are programmable, independent control, lead to The setting of PTT key-press modules, PTT buttons one, PTT buttons two, PTT buttons three is crossed, user can be by each button to right Say that the type of machine calling is modified, flexibly, user-friendly, the output terminal of PTT buttons one is electrically connected with operability MCU module, MCU module set corresponding type of call to each PTT buttons, by the setting of MCU module, to each by bonded Mouthful level change is detected, and then changes the type of call said machine, the output terminal of PTT buttons two and PTT buttons three with The input terminal electrical connection of MCU module, the output terminal of MCU module are electrically connected with radio-frequency module, and radio-frequency module includes receiving and transmitting signal mould Block and speech processing module by the setting of radio-frequency module, play the role of receiving and transmitting signal and speech processes.

When in use, user is by being programmed PTT buttons one, PTT buttons two and PTT buttons three so that each Button can then press PTT buttons one, PTT buttons two and PTT buttons three respectively, then MCU detects phase with independent control Keystroke interface level change is answered, and then has changed the type (generally calling, group is exhaled, individual calling etc.) for saying machine calling, then passes through radio frequency mould Block receiving and transmitting signal is simultaneously handled voice, so as to reach the flexible effect of more PTT intercoms operability.
