Description
Technical field
The present invention relates to intercom technical field, specifically a kind of mobile law enforcement multifunctional interphone.
Background technique
Intercom, it is a kind of bidirectional mobile communication instrument, in the case where not needing any network support, so that it may logical
Words are generated without telephone expenses, suitable for relatively fixed and frequently conversing occasion.Intercom has three categories at present: analog walkie-talkie,
Digital walkie-talkie, IP intercom.
The working principle of intercom is as follows: emitting portion: phaselocked loop and voltage controlled oscillator (VCO) generate the radio frequency emitted and carry
Wave signal, by Hyblid Buffer Amplifier, excitation amplification, power amplifier generate specified radio-frequency power, by antenna low-pass filter, inhibit
Then harmonic components are launched by antenna；Receiving portion: receiving portion is by the amplified signal from radio frequency and comes from locking phase
First local oscillation signal of ring frequency synthesizer circuit is mixed at the first frequency mixer and generates the first intermediate-freuqncy signal.First intermediate frequency letter
Number the noise signal of neighboring trace is further eliminated by crystal filter.Filtered first intermediate-freuqncy signal enters IF process core
Piece, is mixed again with the second local oscillation signal and generates the second intermediate-freuqncy signal, and the second intermediate-freuqncy signal is filtered out by a ceramic filter
It after useless spurious signal, is amplified and frequency discrimination, generates audio signal.Audio signal passes through amplification, bandpass filter, postemphasises
Circuit amplifies, drive the speaker, information needed for obtaining people into volume control circuit and power amplifier；Modulated signal
And modulation circuit: the speech of people is converted into the electric signal of audio by microphone；Signaling processing: CPU generates CTCSS/CDCSS letter
Number by amplification adjustment, be modulated into voltage controlled oscillator.The low frequency signal obtained after frequency discrimination is received, a part is by amplification
It is filtered shaping with infrasonic bandpass filter, into CPU, is compared with preset value, its result is controlled into audio function
Put the output with loudspeaker.It is i.e. if identical as preset value, loudspeaker is opened, if it is different, then mute speaker.
Traffic police personnel generally only use video recorder and carry out law enforcement record at present, record it is in the form of a single, can not be with other
Law enfrocement official carries out communication exchange, and video recorder is generally more heavy, not readily portable movement.Chinese patent (bulletin thus
Number: a kind of mobile law enforcement hand-held device based on Internet of Things CN109274911A) is disclosed, it includes seal cover board, information storage
Storage, message handler, view finder unit, anti-slip layer, protective shell, operator control panel, battery, battery allowance show table, signal antenna,
Signal adapter, intercom, camera, filter, orientation sounder resonator and angle demodulator, although the device is to a certain extent
Guarantee to be imaged while law enforcement operation is linked up, but in actual operation, need traffic police personnel using additional instrument into
Row test, the antenna setting for using inconvenient while current intercom is also unreasonable, needs further to change
Into.
