Problems solved by technology

[0004] However, the requirements for the intercom system in many occasions do not require the intercom system to have a very powerful video intercom function. It only needs to be able to realize simple intercom and protect the privacy of customer intercom, while traditional intercom cannot implement a function like this

Embodiment 1

[0064] Signal collection, the sub-terminal collects the user's voice information through the pickup, and converts the voice signal into an analog signal, the single-chip microcomputer converts the received analog signal into a digital signal, and the digital frequency shift unit adjusts the frequency amplitude of the received digital signal In a straight line, the power amplifier unit amplifies the power of the received digital signal, and the terminal control module judges the key commands on the LCD touch screen. If the judgment result is broadcast mode, the terminal control module controls the second switch of all terminals on the line In the power-on state, the D / A converter converts the received digital signal into an analog signal and transmits it to each terminal, and repeats step 1, and the controller in the power amplifier system can also communicate with the terminal system through the second audio and microphone exchange information with users.

Embodiment 2

[0066] Signal collection, the sub-terminal collects the user's voice information through the pickup, and converts the voice signal into an analog signal, the single-chip microcomputer converts the received analog signal into a digital signal, and the digital frequency shift unit adjusts the frequency amplitude of the received digital signal into straight line, the power amplifier unit amplifies the power of the received digital signal, and the terminal control module judges the key commands on the LCD touch screen. If the judgment result is a discussion group mode, the terminal control module receives the name of the designated terminal input by the user, And control the second switch of the user-designated terminal on the line to be in the power-on state, and the other terminals to be in the power-off state. The digital / analog converter converts the received digital signal into an analog signal and transmits it to the user-designated terminal, and repeats step 1.

Abstract

The invention discloses a multi-party real-time intercom system which comprises a terminal system, an amplification system, a second loudspeaker and a microphone. The invention further discloses a data flow of the multi-part real-time intercom system. The intercom system which is as low in price as an interphone but is different from other intercom systems, can be installed through one wire, can communicate in a talk-back mode through radio and can also build a discussion group capable of protecting privacy of customers is developed and achieved, and the intercom system can be conveniently used in the fields of bull sessions, villas, production lines and the like and is worthy of being widely popularized.

Description

technical field [0001] The invention relates to an intercom system, in particular to a multi-party real-time intercom system and its data flow. Background technique [0002] At present, the intercom systems on the market generally use walkie-talkies. Traditional walkie-talkies have the advantages of small size and easy portability, but they also have the disadvantages of low power, high noise, howling, and current sound during daily use. For other intercom systems, such as the visual intercom system using WIFI, the quality of the call depends on the quality of the WIFI signal, which is high in cost and low in reliability, which is not conducive to realization; but if the intercom system using wired transmission mode, It generally adopts a multi-wire system, and there are many difficulties in its installation and maintenance, which is not conducive to system optimization. [0003] The one-line intercom system is easy to install, easy to maintain, reliable in quality, and low...
