Description
Technical Field
The invention relates to the technical field of interphones, in particular to a method for realizing duplex talkback by a POC cluster communication module.
Background
As is well known, through the development of the last century, the application of the interphone is very common, and the interphone goes from the specialized field to the common consumption and extends from military use to civil use. It is a professional wireless communication tool in mobile communication, and is a consuming tool with the characteristics of consumer products, which can meet the living needs of people. An intercom is a terminal device that communicates from point to multipoint, allowing many people to communicate with each other at the same time, but only one person can talk at the same time. Compared with other communication modes, the communication mode has the characteristics that: instant communication, one-click, economy and practicality, low operation cost, no consumption of call charge, convenient use, and the functions of group calling broadcasting, system calling, confidential calling and the like. In the process of handling emergency accidents or carrying out dispatching commands, the role of the emergency communication system is not replaced by other communication tools.
At present, the transmission mode of data on a line can be divided into simplex communication, half-duplex communication and full-duplex communication, namely, a receives and B sends and receives simplex communication; when A sends to B, it can receive the signal that B sends to A at the same time and call the duplex; a can receive B and B can receive A and send, but can't carry on the half duplex of the call at the same time. In data communication, the conventional interphone generally adopts half-duplex transmission, and information receiving and information sending cannot be performed simultaneously. When using the interphone, one person speaks, and other people can not insert the phone. If someone speaks, the person wants to speak only after he finishes speaking, or has a higher priority to interrupt.
Disclosure of Invention
In view of the above disadvantages in the prior art, the present invention provides a method for implementing duplex talkback by a POC trunking communication module.
In order to achieve the purpose, the invention adopts the following technical scheme:
a method for realizing duplex talkback by a POC cluster communication module comprises the following steps:
the method comprises the following steps:
s1, establishing a group, arranging interphones needing group communication into a communication cluster according to IDs distributed by a server, logging in an ID for each interphone, defining each interphone as a subunit and binding corresponding IDs;
s2, single-person conversation processing, wherein an interphone A is pressed down a ppt speech key, the interphone sends a speech starting signaling to a server, then the subunit records the speech of a speaker by means of a microphone, obtains PCM format speech data and encodes the PCM format speech data, then continuously packs the data and sends the data to the server, each data packet carries ID information of a sender, the step S4 is entered, when the ppt speech key is released, a speech ending signaling is sent to the server, and a receiver judges that one speech is ended after receiving the data;
s3, multi-person conversation processing, wherein when the interphone A does not finish speaking, the interphone B presses a ppt speaking key to send a speech starting signal to the server, the interphone B also records PCM format voice data of a speaker by means of a microphone of the interphone B, echo cancellation is carried out on the recorded PCM format data, sound played by a loudspeaker of a microphone bar is prevented from being recorded from the microphone, the voice data is subjected to voice coding the same as that in the step 2, then the voice data is packaged and sent to the server, each data packet carries ID information of the interphone B and simultaneously enters the step S5, when the ptt speaking key is released, a speech finishing signal is sent to the server, and the server and a receiver judge that the interphone B finishes speaking for one time after receiving the data;
s4, single-person conversation processing is carried out on the server, the server receives the voice data packet sent by the interphone A and distributes the data packet to other members in the group, the interphones of the other members firstly analyze the data packet after receiving the data packet, the ID information and the voice data of the sender are extracted and then play is carried out, and the A is displayed when talking;
s5, carrying out multi-person mixed call processing by a server, simultaneously receiving data packets sent by the butt-joint machines A and B by the server, screening the data packets, preventing the butt-joint machines A and B from receiving own data packets again, simultaneously distributing the voice packets of the butt-joint machines A and B to other members in a group by the server, simultaneously receiving the data packets of the butt-joint machines A and B by the other members, then decoding the data packets, synthesizing and playing decoded PCM data, and displaying the talking of the butt-joint machines A and B, wherein for the interphone A and the B, the server can remove the data packets corresponding to the interphone A or the B and only receives the data packets except the interphone A and the interphone B;
s6, standby, waiting for the interphone to press the ppt talk button, if yes, entering the step S2 or the step S3, and if no, keeping the standby state.
Preferably, in the steps S4 and S5, when the intercom packs the data and sends the data to the server, the intercom selects an appropriate number of frames according to the current network quality to perform packetization and numbering, and then sends the packetized data to the server, and the server distributes the packetized data to members in the group, and after the intercom for receiving the data receives the data packets, the intercom for receiving the data combines the sequentially received packetization in sequence.
Preferably, when the group member is a member of the receiving party, the group member receives a signal for starting speech from the sending party, and the receiving party opens the loudspeaker to prepare for playing; and then receiving the data packet, analyzing the data packet, extracting ID information, data packet numbers and voice data of a sender from the data packet, decoding the voice data according to IDs of different speakers, selectively carrying out voice synthesis and noise reduction when a plurality of speakers speak, finally broadcasting through a loudspeaker, and simultaneously displaying the names of all the speakers to an interface with a UI.
By adopting the scheme, the invention mainly depends on the server to receive the voice data of all speakers at the same time, so that the speakers receive the voice data of all speakers and the speakers receive the voice data of other speakers except the speakers, thereby the whole interphone can realize duplex talkback and increase communication efficiency.
