Description
Technical field
The invention belongs to intercom technical fields, are related to a kind of multiband intelligence intercom, are operated in intercom
Amateur band and public's intercom frequency range make different use legal can use intercommunication machine equipment per family.
Background technology
Existing communication equipment, especially intercommunication machine equipment, it is a kind of bidirectional mobile communication instrument, is not needing to be any
In the case of network support, it is possible to converse, be generated without telephone expenses, suitable for being relatively fixed and the occasion of frequently conversing, in day
Often in life and in terms of outdoor sports and emergency relief, there is highly important effect.But due to there is no the relaying of base station
Effect, the radio-frequency transmissions for relying solely on unit communicate so that the water of mobile phone is much not achieved in intercom on communication distance
It is flat.Simultaneously as using High power radios, other may be interfered with the equipment of frequency range, therefore, country is right
Use frequency range, the transmission power of intercom are limited, simultaneously, it is desirable that use the people of relatively powerful wireless device
Hold license, therefore, for amateurish intercom, since its transmission power is mostly 5W or so, ordinary user needs to be admitted to nothing
The electrically operated grade card of line, intercom put on record and can use, therefore ordinary user is illegal using this kind of intercom.
But for public's intercom, transmission power 0.5W, country is not restricted to the use of this kind of intercom, i.e.,
It can be used without accredited；But due to its fixed frequency point and smaller transmission power so that its experience is poor.When user takes
After obtaining legal license, when wanting to experience powerful talk back equipment, it has to purchase of equipment again, moreover, to use simultaneously
The two frequency ranges then need to carry different intercoms.
For such case, the present invention provides a kind of multiband intelligence intercom, including the shell with three-proof design,
Installation master control borad inside the shell, installation inside the loudspeaker of master control borad electrical connection, fixing shell inside the housing with giving
The battery of master control borad power supply, the knob for being installed on for the first knob of channel switching on shell and adjusting for audio and use
In the PTT button of voice exhalation control；Include Power Management Unit, processor unit, radio frequency unit, power amplifier list on master control borad
Member, battery are connected to the corresponding position of Power Management Unit, and radio frequency unit is electrically connected with processor unit, and power amplifier unit is with penetrating
Frequency unit is electrically connected；Further include the bluetooth unit being placed on master control borad, the bluetooth unit and the processor list on master control borad
The corresponding electrical connection of member.By a radio circuit, switching antenna is so as to fulfill in multiple band operations so that intercom can
To be adapted to different crowds.
Invention content
It is an object of the invention to existing amateurish intercom is overcome not have public's intercom pattern, the personage without operation card
Operate the problem of illegal.
For this purpose, the invention discloses a kind of multiband intelligence intercom, including the shell with three-proof design, mounted on outer
Master control borad, installation in shell inside the microphone of master control borad electrical connection and loudspeaker, fixing shell inside the housing with giving

The corresponding electrical connection of member.By bluetooth unit, intercom may be coupled to the smart machines such as mobile phone or tablet computer, pass through intelligence
Energy equipment carries out relevant configuration to intercom.
Above-mentioned intelligence intercom at least two antennas；Wherein, first antenna is fixedly welded on master control borad, which is public affairs
The antenna of many intercoms, because being provided according to national policy, public's intercom is fixed as 20 channels, and transmission power must not exceed
0.5W, antenna do not allow to change.Therefore, when intercom is operated in public's intercom pattern, first antenna is switched on, due to
One natural barrier is welded on master control borad, so non-exchange.Other antenna（7X）Pacified by the antennal interface installed on the shell
Dress, antennal interface electrical connection corresponding with master control borad；The antennal interface can be compatible with city using ripe SMA interfaces
Antenna on field, user can be replaced according to demand.When only intercom is linked into non-public intercom pattern, the antenna
Interface is just switched on, and could use the channel.Switching between first antenna and other antennas, by being located at master control on-board switching list
Member control.
A kind of above-mentioned multiband intelligence intercom, further includes the display screen for being embedded in case surface；The display screen with
Processor unit on master control borad corresponds to electrical connection.The information such as electricity, signal, pattern and frequency point can be shown on display screen.This
In processor STM32 series processors can be used, for using STM32 processors complete display screen driving, switch control etc. journeys
Sequence, for the those skilled in the art, the easy acquisition of energy belongs to known technology.
Above-mentioned a kind of multiband intelligence intercom, due to can at least be operated in public's intercom pattern and amateurish intercom
Under pattern, radio frequency unit used in various patterns is shared module, so, radio frequency unit can at least be operated in two frequency ranges
In the range of；Except of course that public intercom frequency range 409.75MHZ-409.9875MHZ, amateur band have it is multiple, except 430MHZ-
Outside 440MHZ, also 144MHZ-146MHZ, therefore radio frequency unit can be operated in multiple frequency ranges.
A kind of above-mentioned multiband intelligence intercom, the bluetooth unit are low-power consumption bluetooth.Its connection can be compatible with general
Logical Android device and ios device.To ensure the aesthetics of display, display screen here is color screen, using the finished product of outsourcing.
The beneficial effects of the invention are as follows：Intercom is configured by smart machine, the hardware of intercom can be simplified
Structure, meanwhile, the cost of intercom can be reduced by means of some hardware devices of mobile phone；Meanwhile setting using multiband
Meter for the people of no radio license, can use public's intercom, for the people with license, can make
With high-power amateurish intercom, so that intercom is adapted to more crowds.
The invention will be further described below in conjunction with the accompanying drawings.
