Abstract
A kind of fire-fighting group wireless communication talkback system, it comprises intercom and group control end, described intercom comprises central processing unit, the audio frequency transceiver module be connected with central processing unit, wireless communication module, SIM card, digital signal transceiver module and power module, and described intercom is connected with described group control end communication by wireless communication module.The utility model solves that traditional intercom call overlay area is limited, call crosstalk and the clear problem of aphthenxia, and solve again mobile communication intercom covers without cellular network when there is natural calamity can the problem of normal talking simultaneously.
Description
Technical field
The utility model relates to a kind of intercom, is specifically related to a kind ofly can to carry out by the network coverage restriction talkback system conversed again having network coverage area domain call.
Background technology
Present stage, intercom is widely used in the industries such as public security, security personnel, civil aviaton, logistics, railway, water conservancy, tourism, tradition intercom is a kind of bidirectional mobile communication instrument, when without any need for network support, just can converse, there is no the generation of telephone expenses, be applicable to relatively fix and the occasion of frequent call.But traditional intercom can only carry out communication session in limited distance, and same frequency spectrum often occurs crowded, the problem of crosstalk and speech intelligibility difference, the number of users therefore on same frequency spectrum is often limited, well can not improve the availability of frequency spectrum.
Along with the shortcoming that traditional intercom appears gradually, existing mobile communication intercom then solves a series of shortcomings of traditional intercom, mobile communication intercom is the one specialty wireless communication facility in mobile communication, can with the same call carrying out long distance in cellular network coverage area of mobile phone, it a kind ofly wireless in movement, can carry out the terminal equipment communicated by point to multi--point, many people can be heard simultaneously, and same people speaks, but can only have a speech at synchronization.Therefore traditional interphone communication crosstalk and the clear problem of aphthenxia is solved.But, a large amount of uses of mobile communication intercom, also its deficiency has been manifested in certain situation, such as at generation City Disasters, earthquake disaster, during dark woods big fire, most communication signal all will be forced to interrupt, and mobile communication intercom loses the covering of communication network and can not converse, thus has a strong impact on the carrying out of rescue work.
Summary of the invention
The utility model provides a kind of fire-fighting group wireless communication talkback system, technical problem of the present utility model be solve that intercom can converse in the region having cellular network to cover again can without the call carried out in cellular network coverage area.
A kind of fire-fighting group wireless communication of the utility model talkback system, it comprises intercom and group control end, described intercom comprises central processing unit, the audio frequency transceiver module be connected with central processing unit, wireless communication module, SIM card, digital signal transceiver module and power module, described digital signal transceiver module comprises transmitter unit, voice recognition unit, receiving element and signal processing unit, the two ends of described voice recognition unit are connected with one end of described transmitter unit and receiving element respectively, described signal processing unit is connected with the other end of described transmitter unit and receiving element respectively, described signal processing unit and described central processing unit are bi-directionally connected, described intercom is connected with described group control end communication by wireless communication module.
Furtherly, the output of described transmitter unit is connected with the input of described voice recognition unit, the input of described transmitter unit is connected with the output of described signal processing unit, the input of described receiving element is connected with the output of described voice recognition unit, and the output of described receiving element is connected with the input of described signal processing unit.
Furtherly, the group control end be connected with described intercom communication comprises master server, and described master server is connected with at least one intercom communication by communication.
Furtherly, described intercom is divided into some groups by described group control end, and the intercom in described same a small group is connected with described master server wireless telecommunications by a child servers.
A kind of fire-fighting group wireless communication of the utility model talkback system by arranging digital signal transceiver module and wireless communication module in intercom, judge that current environment is applicable to the pattern conversed by central processing unit, select suitable call mode, thus solve that traditional intercom call overlay area is limited, call crosstalk and the clear problem of aphthenxia, solve again mobile communication intercom covers without cellular network when there is natural calamity can the problem of normal talking simultaneously, substantially increases the scope of application of the utility model intercom.
Accompanying drawing explanation
Fig. 1 is the structure chart of a kind of fire-fighting group wireless communication of the utility model talkback system.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, execution mode of the present utility model is described in further detail.
Refer to Fig. 1 to illustrate, talkback system of the present utility model, comprise intercom 10 and group control end 20, described intercom 10 comprises central processing unit 100, the audio frequency transceiver module 200 be connected with central processing unit 100, wireless communication module 300, SIM card 400, digital signal transceiver module 500 and power module 600, described digital signal transceiver module 500 comprises transmitter unit 510, voice recognition unit 520, receiving element 530 and signal processing unit 540, the two ends of voice recognition unit 520 are connected with one end of transmitter unit 510 and receiving element 530 respectively, signal processing unit 540 is connected with the other end of transmitter unit 510 and receiving element 530 respectively, signal processing unit 540 and central processing unit 100 are bi-directionally connected, intercom 10 is connected with group control end 20 communication by wireless communication module.
Wherein, the output of transmitter unit 510 is connected with the input of voice recognition unit 520, the input of transmitter unit 510 is connected with the output of signal processing unit 540, the input of receiving element 530 is connected with the output of voice recognition unit 520, and the output of receiving element 530 is connected with the input of signal processing unit 540.
The group control end 20 be connected with intercom 10 communication comprises master server, master server is connected with at least one intercom 10 communication by communication, intercom 10 is divided into some groups by group control end 20, be connected with master server wireless telecommunications by a child servers with the intercom 10 in a small group, master server obtains the situation of interphone terminal in real time by child servers, namely master server realizes grouping management, with in a small group intercommunication function realize one to one by or one-to-many converse simultaneously.
Although by referring to some preferred implementation of the present utility model, the utility model illustrated and describe, but those of ordinary skill in the art should be understood that and can do various change to it in the form and details, and does not depart from spirit and scope of the present utility model.
