Embodiment 1

[0025] Embodiment one: see figure 1 , the community intelligent wireless voice message communication system, including a group of main controllers 1 and corresponding groups of user terminals 2, characterized in that the main controller 1 and the user terminals 2, between the user terminals 2 through wireless The exchange and transmission of voice signals is carried out in a manner, and a wireless multipoint-to-multipoint communication protocol is adopted to form a wireless voice signal communication network. The user terminal 2 has the function of storing and playing voice messages.

Embodiment 2

[0026] Embodiment 2: This embodiment is the same as Embodiment 1, and the special feature is: see figure 2 , the structure of the main controller 1: a wireless transceiver unit 101 is connected to a microprocessor 103 through an I / O port 102, and the microprocessor 103 is connected to a keyboard control unit 104 and a voice codec unit 105. This voice encoding unit 105 is connected with a built-in microphone 106 and a built-in loudspeaker 107, and a power supply circuit 108 provides operating power for each component unit; Input commands to the microprocessor 103 by the described keyboard control unit 104, and the microprocessor 103 controls the The working mode of the wireless transceiver unit 101, when the built-in microphone 106 has a voice signal input, the signal is transmitted to the voice codec unit 105 through the I / O port 102, and the voice codec unit 103 in the microprocessor 103 Under control, after the signal is processed a series of times, the coded signal is sent...

Abstract

The invention relates to an intelligent wireless voice mail communication system of a cell, which adopts a half-duplex wireless communication mode, processes voice signals by ADPCM (adaptive differential pulse code modulation) codec and comprises a group of main controllers and a plurality of groups of user terminals. The intelligent wireless voice mil communication system transmits digitized voice signals inside an area and realizes the intelligent wireless voice mail communication in the whole area by selecting voice real-time communication or voice main communication. Different from a common walkie-talkie, the intelligent wireless voice mail communication system can retain multiple voice mails, play repeatedly and move in a wireless mode, thereby being convenient. The system has the advantages of convenient use and strong practicality and can be used for places, such as office buildings, residential quarters, hotels, and the like.

Description

technical field [0001] The invention mainly relates to the fields of information transmission and wireless communication, in particular to a wireless voice message communication system which is convenient for community users and has the functions of real-time communication and storage of messages. technical background [0002] The existing residential building access control system, on the one hand, uses wired transmission, which is extremely inconvenient for wiring; on the other hand, this type of system has a single function and cannot meet many changing situations in reality. Contents of the invention [0003] The purpose of the present invention is to provide a set of community intelligent wireless voice message communication system capable of real-time communication and storage of messages. This system is easy to use and highly practical, and can be used in office buildings, residential quarters, hotels and other places. [0004] In order to achieve the above object,...
