Abstract
A vehicle-mounted interphone conducting receiving at two frequency bands simultaneously is mainly composed of a first receiving unit, a second receiving unit, a first speech receiving unit, a second speech receiving unit, a voice frequency switching unit and a speech sending unit. The first receiving unit and the second receiving unit are used for receiving carrier wave signals at different frequency bands, electrically connected with the voice frequency switching unit through wires and connected with an antenna. The first speech receiving unit and the second speech receiving unit are electrically connected with the voice frequency switching unit, and the speech sending unit is electrically connected with the voice frequency switching unit. The interphone can receive carrier waves signals at two different frequency bands simultaneously, the problem that an existing vehicle-mounted interphone is only provided with a single-frequency-band receiver, and the conversation content of two different frequency bands can be received simultaneously only by additionally arranging a vehicle-mounted interphone of the other frequency band is solved, communication cost is saved, repeated purchase is avoided, and communication can be more flexible and more timely.
Description
The application is the divisional application of " having the Vehicular intercom that two-band can receive simultaneously ", and the application number of original application is 201210113598.6, and the applying date is 2012/04/18.
Technical field
The present invention relates to Vehicular intercom, what be specifically related to is the Vehicular intercom that a kind of two-band receives simultaneously.
Background technology
Intercom is commonly called as, and " walkie-talkie, walkie-talkie are the communication tools of a kind of specialty of mobile communication, and it has can make to put many people and carry out call simultaneously and exchange, and it can make many people can receive the call audio frequency of the transmitter of same frequency range simultaneously.Its feature is: instant messaging, gets ready to go into action in hundreds, and operation cost is extremely low, does not expend communication fee, easy to use, also has that group calling is logical to be broadcast simultaneously, and system calling, confidential calls various functions is a kind of main communication tool of emergency communication.
Current Vehicular intercom is on the market all the intercom of single frequency band, namely traditional Vehicular intercom only has a receiver, although it receives the receiver that can be set to many different frequent points, set frequency can only be same frequency range, the frequency range of work is single, unmodifiable.As the intercom of VHF (30-300MHz) frequency range intercom or UHF (300-3000MHz) frequency range.
Above-mentioned traditional intercom receives the communication of other frequency range as needed, just must purchase the intercom of other frequency range simultaneously.Use the intercom of two different frequency ranges to realize receiving while two frequency ranges, this means of communication cause communication cost to increase, and install inconvenience, other inconveniences such as data waste.
Summary of the invention
The object of the invention is the deficiency for above technology, the Vehicular intercom that a kind of two-band that can simultaneously receive two different frequency range carrier signals receives simultaneously is provided.
The present invention is achieved by the following technical solutions:
The Vehicular intercom that two-band receives simultaneously, is mainly made up of receiving element one, receiving element two, called unit one, called unit two, audio switching unit and telecommunication unit.
Described receiving element one and receiving element two receive the carrier signal of different frequency ranges respectively, and receiving element one and receiving element two are electrically connected respectively by wire and audio switching unit, receiving element one and receiving element two couple together with antenna respectively.
Also be provided with switching device between above-mentioned receiving element one and audio switching unit, between receiving element two and audio switching unit, be also provided with switching device.
Described called unit one and called unit two are electrically connected with audio switching unit respectively, and telecommunication unit and audio switching unit are electrically connected.
Be provided with switching device between above-mentioned called unit one and audio switching unit, between called unit two and audio switching unit, be also provided with switching device.
Above-mentioned receiving element one, audio switching unit and called unit one and receiving element two, audio switching unit and called unit two are operated in respective band limits respectively; And receiving element one and receiving element two are operated in reception state simultaneously, called unit one and called unit two are operated in audio frequency simultaneously and amplify operating state.
Beneficial effect of the present invention embodies and is: compared with prior art, intercom of the present invention can receive the carrier signal of two different frequency ranges simultaneously, solve the receiver that current Vehicular intercom only has single frequency band, only has the dialog context simultaneously could listening to two different frequency ranges by putting other frequency range Vehicular intercom again, save communication cost, avoid purchasing of repetition, make communication more flexibly in time.
