Abstract
A four-waveband transmission vehicle-borne interphone is composed of transmission units, a transmission switching unit and a call sending unit, wherein the transmission units are electrically connected with the transmission switching unit and are connected with an antenna, and the transmission switching unit is electrically connected with the call sending unit. The transmission units include a transmission unit One, a transmission unit Two, a transmission unit Three and a transmission unit Four and respectively transmit carrier signals of different frequency bands. The four-waveband transmission vehicle-borne interphone of the invention can transmit carrier signals of four different frequency bands, overcomes the defect that the prior interphone can only transmit carrier signals of a single frequency band and helps to avoid repeated purchases, save communication cost and enable communication to be more convenient, more flexible and more timely.
Description
Technical field
The invention belongs to Vehicular intercom technical field, what be specifically related to is a kind of Vehicular intercom with four band emission frequencies.
Background technology
Intercom has hand-held set, the various ways such as vehicular and Backpack type, it is a kind of professional communication tool of mobile communication, extensively employ in traffic, security protection, forestry, water conservancy, in the multiple industry such as disaster prevention and control, its feature is to make many people interchange of simultaneously conversing, can make many people receive the call audio frequency of the transmitter in the some frequencies of same frequency range simultaneously, it is a kind of instant messaging, get ready to go into action in hundreds, do not expend communication fee, operating cost is extremely low easy to usely has that group calling is logical to be broadcast simultaneously in addition, system is logical calls out, secret calling waits various functions, it is a kind of main communication tool of emergent call.
It is the intercom of single wave band that current Vehicular intercom on the market has, the Vehicular intercom that is reception room system only has a single reflector, although it can launch many different frequencies, fill must be in a wave band falls scope to set frequency, and frequency is single immutable.
Above-mentioned traditional intercom is as need to be just purchased the machine of saying of other frequency range with the intercom communication of other frequency range again, as need to be just purchased again the intercom of 3 other frequency ranges with the communication of 4 frequency range intercoms, and 4 intercoms complete with 4 wave bands on intercom carry out communication, this communication modes can cause communication cost to increase, inconvenience is installed, the inconveniences such as the wasting of resources.
Summary of the invention
The object of the invention is the deficiency for above technology, a kind of four band emission Vehicular intercoms of launching multi-frequency section are provided.
The present invention is achieved by the following technical solutions: four band emission Vehicular intercoms, by transmitter unit, transmitting switch unit and telecommunication unit, formed, this transmitter unit is electrically connected with transmitting switch unit, transmitter unit also couples together with antenna, and transmitting switch unit and telecommunication unit are electrically connected.
This transmitter unit comprises transmitter unit one, transmitter unit two, transmitter unit three and transmitter unit four, and this transmitter unit is launched respectively the carrier signal of different frequency range separately.
Described transmitter unit one is also provided with switching device between being connected with transmitting switch unit.
Described transmitter unit two is also provided with switching device between being connected with transmitting switch unit.
Described transmitter unit three is also provided with switching device between being connected with transmitting switch unit.
Described transmitter unit four is also provided with switching device between being connected with transmitting switch unit.
Beneficial effect of the present invention embodies and is: compared with prior art, the present invention launches the different carrier signal that intercom one machine can be launched four frequency ranges, solve current intercom and can only launch the carrier signal defect of single audio range frequency, avoided repeating to purchase, saved communication cost, made that communication is more convenient makes communication more flexibly in time flexibly.

Embodiment
As shown in Figure 1, four band emission Vehicular intercoms, are comprised of transmitter unit, transmitting switch unit 5 and telecommunication unit 6, and this transmitter unit is electrically connected with transmitting switch unit 5, transmitter unit also couples together with antenna 7, and transmitting switch unit 5 is electrically connected with telecommunication unit 6.
This transmitter unit comprises transmitter unit 1, transmitter unit 22, transmitter unit 33 and transmitter unit 44, and this transmitter unit is launched respectively the carrier signal of different frequency range separately.
Between described transmitter unit and transmitting switch unit 5, be connected with separately control switch.
Described transmitter unit 1, transmitting switch unit 5 and telecommunication unit 6 are operated in wave band one scope, transmitter unit 22, transmitting switch unit 5 and telecommunication unit 6 are operated in wave band two scopes, transmitter unit 33, transmitting switch unit 5 and telecommunication unit 6 are operated in wave band three scopes, transmitter unit 44, transmitting switch unit 5 and telecommunication unit 6 are operated in wave band four scopes, and wave band one to wave band four is four wave bands of different frequency scope.
As shown in Figures 1 to 5, the specific works process of intercom of the present invention is: by saying that with Vehicle mounted station knot the software frequently of writing that machine matches sets four Frequency points as the tranmitting frequency of intercom transmitter unit 1, transmitter unit 21, transmitter unit 31, transmitter unit 41, or set the frequency of four different-wavebands as the tranmitting frequency of four transmitter units by the keyboard of Vehicular intercom.
As shown in Figures 2 to 5, shown in the panel of Vehicular intercom divide left and right two regions, left area can arrange four kinds of different-wavebands frequency that falls, and as the tranmitting frequency of four transmitter units of Vehicular intercom.
One, preparation is set
First by button, choosing the region on the left side is setting area, chooses rear left area to have " ▼ " symbol to show.
Two, frequency is set
(1) select keyboard and enter interface is set by [2], now shake and show 8 road whippletrees in this district, and it is bright that the symbol that simultaneously " has F " is handed over, at this moment please export successively and make front 6 bit digital of required frequency, after the digital value Lookup protocol of two.
(2) repeating step (1) arranges 3 frequencies of other 3 wave bands.
Three, transmitting carrier signal
Button [3] is that wave band switches shortcut, often by once convert a wave band, the frequency of the last storage of this wave band or use is recalled and as the shave one's head transmitting frequency of emitter of this wave band simultaneously.
(1) first by button, choosing middle left area is emitter region, and now the left side is that " ▼ " symbol shows.
(2) by button [3], choose after the frequency of selecting wish transmitting, by [PTT] emission key, converse.
