Intercom capable of self-defining and broadcasting channel name and self-defining method thereof

Abstract

The invention relates to wireless intercoms, in particular to an intercom capable of self-defining and broadcasting a channel name and a self-defining method of the intercom. The intercom comprises a master control circuit, a baseband signal processing circuit, an RF transceiver circuit, an MIC voice collecting circuit, an antenna and a loudspeaker. The master control circuit is further connected with a channel broadcasting and decoding circuit, a channel broadcasting and amplifying circuit and the loudspeaker sequentially in series. The master control circuit is in bidirectional intercommunication with a channel broadcasting and storage circuit. The MIC voice collecting circuit is connected to the channel broadcasting and storage circuit after passing through a channel broadcasting and encoding circuit and the channel broadcasting storage circuit in sequence. Audio is edited to serve as the special channel name and stored to an appointed address by utilizing the MIC voice collecting circuit; afterwards, the corresponding channel audio address is selected according to a channel so that an audio file can be called out and played. In this way, the function of user-friendly self-defining channel name voice broadcasting is achieved, and therefore a user can more flexibly and quickly use a voice broadcasting functional zone branch channel and a special marking channel of the intercom.

Description

technical field [0001] The invention relates to a wireless walkie-talkie, in particular to a walkie-talkie capable of customizing channel names and broadcasting and a customizing method thereof. Background technique [0002] The walkie-talkie is a two-way mobile communication tool. You can talk without any network support, and there is no call fee. As long as the frequency of the walkie-talkie is the same, any walkie-talkie in the same organization can receive it from other walkie-talkies. Applicable For relatively fixed and frequent calls. In recent years, walkie-talkie technology has developed rapidly and matured. However, the fixed voice chip used for channel broadcasting of the existing walkie-talkie channel has a small storage space, and the voice data cannot be changed. Once you want to change the voice data of the channel broadcast, you need to replace it. The hardware circuit has a long product development cycle, and it is difficult to adapt to the rapidly changing ...

In recent years, walkie-talkie technology has developed rapidly and matured. However, the fixed voice chip used for channel broadcasting of the existing walkie-talkie channel has a small storage space, and the voice data cannot be changed. Once you want to change the voice data of the channel broadcast, you need to replace it. Hardware circuit, product development cycle is long, it is difficult to adapt to the rapidly changing needs of the market

In reality, in a large hotel, employees have different divisions of labor. Employees of different types of work can be divided into management, reception, logistics, security and other departments. Traditional walkie-talkies can only define the channels used by different departments as "channel 1", "Channel 2", "Channel 3", "Channel 4" and so on, although each channel has a name, but the function of each channel cannot be clearly distinguished, which brings a huge burden to the new employees who do not understand the hotel
