The invention provides a remote cross-region intercom system based on the cooperative networking of the Internet and a software interphone 4, which comprises the following components: the system comprises a software intercom control system 1, a hardware intercom gateway 2, a traditional wireless intercom 3 and a software intercom 4.
The software intercom control system 1 is used for performing intercom group configuration and intercom right arbitration on a software level, processing an audio stream and then distributing the processed audio stream to the hardware intercom gateway 2 and/or the software intercom 4.
The hardware intercom gateway 2 is used for communicating with the traditional wireless intercom 3 and establishing a call with the software intercom control system 1, and transmitting an audio stream and a behavior request sent by the traditional wireless intercom 3 to the software intercom control system 1.
The conventional wireless intercom 3 is used for being interconnected with other interphones and the hardware intercom gateway 2 in the frequency modulation channel where the wireless intercom is located.
The software interphone 4 is used for establishing a call with the software interphone control system 1 and sending an audio stream and a behavior request.
Specifically, the software intercom control system 1 is developed based on a Linux operating system and is used for realizing the work of intercom group configuration, intercom right arbitration, audio stream processing and the like at a software level. The device may access the talkback group via SIP protocol or proprietary protocol.
Further, the hardware intercom gateway 2 includes: a gateway upper link side and a gateway lower link side.
The gateway uplink side is used for establishing a call with the software type intercom control system 1 by utilizing the SIP communication protocol by using the Internet.
A gateway lower link side for communicating with the conventional wireless intercom 3 using a radio communication means.
Specifically, the hardware intercom gateway 2 implements two types of connections:
(1) The gateway underside communicates with the conventional wireless intercom 3 by means of radio communication, and the communication distance of this part is limited by the radio transmission distance.
(2) The gateway uplink side establishes a call with the software intercom control system 1 by using an internet and utilizing an SIP communication protocol, and utilizes an RTP protocol to send an audio stream sent by the traditional wireless intercom 3 connected below the gateway uplink side to the software intercom control system connected above, and a DTMF signal appointed by the RTP protocol sends a behavior request of applying for speaking and stopping speaking to the software intercom control system 1; and the audio stream sent by the hardware intercom gateway 2 from other APP (software intercom 4) or other networking is converted into the radio signal used by the traditional intercom and sent to the traditional wireless intercom 3 connected with the wireless intercom. This part of the communication relies on the internet and is not limited by the radio transmission distance.
Specifically, the conventional wireless intercom 3 is interconnected with other intercom and the hardware intercom gateway 2 in the frequency modulation channel where it is located, and their voices are transmitted by radio.
Further, the software interphone 4 is used for establishing a call and transmitting an audio stream with the software interphone control system 1 through the SIP protocol and the RTP protocol; and for transmitting its behavior request using a proprietary protocol.
Specifically, the software interphone 4 is software developed by software and capable of running on a smart phone, a tablet and a computer, and the software is cross-platform based on Linux, windows, android, iOS. The use habit of the wireless interphone is simulated. The software interphone 4 establishes a call and transmits an audio stream with the software interphone control system 1 through a SIP protocol and an RTP protocol; the private protocol is used to transmit the behavior requests of 'apply for talk' and 'stop talk'. This part of the communication is internet dependent and is not limited by the radio transmission distance.
The deployment and communication modes between the above main components are shown in fig. 2.
The invention also provides the following additional technical proposal to improve the reliability and high performance of the whole proposal:
(1) By utilizing the characteristic that a few people usually speak a plurality of people to listen in an intercom scene, the audio stream of a listener adopts a one-time coding and multiplexing distribution strategy to reduce the coding pressure of audio output so as to greatly enlarge the number of users which can be supported by the system;
(2) Because only one person can take the speaking right at a time in the intercom scene, aiming at the problem that communication cannot be continued due to abnormal occupation of the speaking right, which is easy to occur in the scene, an RTP audio stream active monitoring, audio stream volume change detecting and software intercom 4 speaking right keep-alive mechanism is provided, the health of the speaking right is monitored, and when the speaking right is found to be abnormally occupied, the speaking right is automatically released by a system, so that other users can normally apply for the speaking right;
(3) Because the hardware intercom gateway 2 may be deployed at any position, the network and the environment of the area where the hardware intercom gateway 2 is located may be unstable, and the software intercom system can automatically recall the hardware gateway under several conditions aiming at the situations of disconnection, abnormality and the like of the hardware gateway so as to complete reconnection as soon as possible.
1. Implementation of listener audio stream "one-time encoding, multiplexed distribution
Because only one speaker exists in the intercom scene, the rest people are listeners, and the voice contents heard by the listeners at the same time are unified, the voice contents can be considered to be cached, and the voices in the same period are multiplexed and sent to the sending stream of the listeners to be sent to the listeners during sending. In the specific implementation, however, there are some variations in detail: because the software interphone 4 (APP) and the hardware interphone gateway 2 both use the SIP protocol to establish a call at the voice connection level with the software interphone control system, different devices may use different voice coding formats (common voice coding includes G711, G722, G729, OPUS, etc.). When the audio stream is sent to the listener terminal, the audio stream needs to adopt the coding format which accords with the terminal requirement and is negotiated in the SIP protocol, and thus, when the audio stream is multiplexed, the audio stream needs to be coded in a plurality of coding formats and needs to be coded in a plurality of times.
The invention thus introduces the concept of a "coded channel", each talkback group, when negotiating a new coding format with the terminal device, establishes a corresponding "coded channel" which codes the sound of the speaker into its own corresponding coding format, and then multicasts the coded channel to the corresponding listener's device using this coding, as shown in fig. 3.
The one-time coding, multiplexing distribution strategy provided by the invention greatly reduces the number of coding processes which consume the most calculation force in the audio processing process, and even if thousands of people exist in the whole intercom group, the number of times of coding in each time slice is only several times.
2. Monitoring of abnormal occupation of speaking right
Due to network fluctuation, abnormal equipment and other reasons, the situation that a certain equipment always occupies the speaking right and other equipment cannot speak may occur. For this reason, a method of automatically detecting abnormal occupation of speaking right and depriving speaking right is required. The invention provides three methods for common use, and the three methods are different for different scenes.
2.1 RTP Audio stream Activity monitoring
The software intercom 4 or the hardware intercom gateway 2 transmits an RTP audio stream to the software intercom control system after being connected to intercom (when speaking, the audio stream is speaking content, and when not speaking, the audio stream is mute packet). The software intercom control system monitors the received RTP audio stream, and if no RTP audio stream is sent by a certain device for 30 seconds, the device is abnormal, or a network between the device and the software intercom control system is abnormal. At this time, if the device is in the speaking state, the software intercom control system releases the speaking right so that other devices apply for speaking. Such anomalies typically occur in the event of network anomalies in the terminal equipment.
2.2 Audio stream volume Change detection
For the audio stream sent by the speaker to the software intercom control system, the software intercom control system monitors and evaluates the volume of the audio stream, and if the volume of the audio stream is found to be unchanged beyond 15 seconds, the user using the device is considered not to be speaking, and the speaking right of the user is relieved, so that other devices apply for the speaking right. The above-described flow is shown in fig. 4. Such a scenario typically occurs in human error operations, such as a person having touched the talk button when he or she does not need to speak, but is not aware of himself or herself, and is always engaged in speaking.
2.3 software interphone 4 speaking right keep-alive
This solution is specific to the software interphone 4 installed on the smart device. Because such devices have proprietary protocols in addition to SIP and RTP that can interact with the software talk control system. When the software intercom 4 applies for speaking right, it will send a request for speaking right keep-alive to the control system by using the private protocol every 3 seconds, if the software intercom control system finds that no two keep-alive periods (6 seconds) are sent for intercom keep-alive, it is considered that the device has network abnormality, and the speaking right is released, so that other devices apply for speaking right. The above-described flow is shown in fig. 5.
Such a scenario is easily presented to a user using a mobile phone terminal, and due to the complexity of the mobile network used by the mobile phone, a sudden network outage situation easily occurs when an application for speaking right is speaking. At this time, even if the user sends a request for "end talk", the software talk control system may not receive the request due to network interruption. After the mechanism is added, the software intercom control system can timely detect network abnormality of the terminal and release speaking right as soon as possible.
3. Hardware intercom gateway 2 is very heavy
The hardware intercom gateway 2 carries out equipment registration and conversation through the SIP protocol, and when the abnormal disconnection of the conversation occurs, the intercom control system can try several times to automatically recall the hardware intercom gateway 2. If the hardware intercom gateway 2 does not reply within the preset time, the re-calling is unsuccessful, and the software intercom control system records which hardware intercom gateway 2 in which intercom group is abnormal. When the hardware intercom gateway 2 performs SIP registration again (at this time, the hardware intercom gateway 2 should have recovered to be normal), if the intercom group in which it is located is still not disassembled, the hardware intercom gateway 2 is called again. The above-described flow is shown in fig. 6.
The above embodiments are only preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present invention are intended to be within the scope of the present invention as claimed.
