Abstract

The utility model discloses a portable wireless IP intercommunication device which includes intelligent handsets and an IP communication server. Multiple intelligent handsets are connected with the IP communication server via a wireless IP network. The portable wireless IP intercommunication device can provide the point-to-point voice intercommunication function based on the wireless IP network (3G/WiFi), and the data transmission of the voice intercommunication is totally IP-based, so the data transmission does not occupy the wireless network voice channel resource of a service provider, and does not generate the communication fee. Besides, the intercommunication between two parties can be carried out without using the telephone number, and the point-to-point direct IP voice communication between two parties can be carried out through selecting a target user at will in an acquired user list after logging in the server. The portable wireless IP intercommunication device is suitable for on-site command, scheduling, and remote rapid voice call.

Description

A kind of portable mobile wireless IP talkback unit

Technical field

The utility model relates to a kind of portable mobile wireless IP talkback unit.

Background technology

Along with the fast development of 3G technology and constantly perfect, be that the mobile radio communication system of core replaces the conventional fixed phone just fast and becomes main flow communication mode now with the mobile phone.Abroad the wireless application based on 3G technology is become better and approaching perfection day by day at present, especially in the public sphere and the large enterprise garden, wireless ip voice direct calling has begun progressively to be received and use by the user.Utilize the data, services ability of the 3G wireless network that operator provides, realize the point-to-point through ip voice calling of mobile phone terminal and mobile phone terminal, got around the legacy voice channel of carrier network fully with the IP technology; Can not produce telephone expenses; Can save a large amount of mobile communication expense costs, especially in metallurgical, manufacturing related application field, occasions such as lots of field production, commander, scheduling, repairing; Utilize mobile phone wireless IP intercommunication can greatly promote communication efficiency; Reduce communications cost, convenient to use, have better market prospect.

Summary of the invention

The utility model technical problem to be solved provides a kind of portable ip voice talkback unit; Satisfy under the environment such as industrial circle produced on-site, commander, scheduling the demand of quick real-time voice communication, can carry out voice data transmission, do not take operator's wireless network voice channel resource based on public 3G wireless network or inner WiFi wireless network; The dispense with telephone number; Do not produce telephone expenses, easy to use, with low cost.

For solving the problems of the technologies described above, the utility model provides a kind of portable ip voice talkback unit, it is characterized in that, comprises smart mobile phone, the IP communication server, and some said smart mobile phones connect the said IP communication server through Wireless IP network.

Said Wireless IP network is public 3G wireless network or inner WiFi wireless network.

Further, the said IP communication server connects said Wireless IP network through the Internet or intranet.

Said smart mobile phone is an Android operating system mobile phone.

Integrated centralized control module, voice acquisition module, data encapsulation module, data restoring module, network transmission module on the said Android smart mobile phone;

Centralized control module is used for voice acquisition module, data encapsulation module, data restoring module have been carried out concentrated multiple task management, two-way processing when realizing the voice transmission and receiving;

Voice acquisition module is used for controlling that the smart mobile phone microphone is accomplished the collection of user voice data and at the internal memory buffer memory;

The packet encapsulation module is used to utilize the smart mobile phone dsp chip to accomplish primary voice data boil down to IP packet;

The packet recovery module is used to utilize the smart mobile phone dsp chip to accomplish IP compressed voice packet and is reduced to the primary voice data bag and pushes to the mobile phone speaker playback;

Network transmission module is used to control smart mobile phone 3G network chip and accomplishes and to set up the TCP/IP network with the other side's mobile phone and be connected, and the transmission and the reception of completion IP packet, and its process adopts asynchronous input and output mode fully, and is clog-free.

The beneficial effect of the utility model:

1, can provide based on the point-to-point speech talkback function of Wireless IP network (3G/WiFi); The transfer of data of its speech talkback is complete IPization; Do not take the wireless network voice channel resource of operator; Can not produce telephone expenses, and intercommunication both sides dispense with telephone number, through to server log and obtain user list and can realize choosing at random the targeted customer and can begin the point-to-point through ip voice communication of both sides.Be applicable to various floor managers, scheduling, the quick voice call communication purposes in strange land.

2, stable performance is outstanding, and voice quality is clear, and real-time is good, and applicable to all kinds of production scenes, commander, dispatch application environment, portable capability is strong, to a certain extent instead of dedicated industry talk back equipment.

Description of drawings

Further specify below in conjunction with accompanying drawing and embodiment technical scheme the utility model.

Fig. 1 is the structural representation of the utility model.

Fig. 2 is the internal module theory diagram of IP wireless interspeaker.

Embodiment

As shown in Figure 1; Present embodiment has provided the Android smart mobile phone 1,2 that connects on public 3G wireless network or the inner WiFi wireless network 3; Public 3G wireless network or inner WiFi wireless network 3 are through the network switch 4 connection the Internets or intranet 6, and the communication server 5 is articulated on the Internet or the intranet 6.

In conjunction with Fig. 1, shown in 2; Reside in each Android smart mobile phone internal memory through centralized control module and to move; Be responsible for the multithreading task management; And control normally working alone of voice acquisition module, packet encapsulation module, packet recovery module simultaneously, the independent simultaneously transmission and the reception of the other side's speech data of accomplishing the local voice data, thereby realization Android smart mobile phone 1, the two way voice communication between 2.Voice acquisition module realizes the collection to user speech through control Android mobile microphone, and image data is pushed to the packet encapsulation module, is accomplished compression and is encapsulated as the IP packet by it.The Android mobile phone utilizes pre-assigned unique sign to sign in to the communication server and obtain the smart mobile phone user list.The IP packet is continuing to push to network transmission module, and this module controls Android cell phone network protocol stack and 3G network hardware device are connected local ip voice data are sent to the other side's mobile phone through setting up TCP/IP with the other side's mobile phone.On the other hand, network transmission module also receives the other side's ip voice data that the other side's mobile phone is sent simultaneously, and pushes to the packet recovery module.The packet recovery module is reduced to primary voice data with the other side's ip voice packet decompress(ion), and control Android speech chip and loud speaker come out the other side's audio playback.Finally, realize local Android mobile phone and the two-way intercommunication function of the IP-based real-time voice of the other side Android mobile phone.
