Abstract
It is to utilize the squelch circuit of ultrashort wave full duplex transceiver to control short-wave transceiver automatically and the ultrashort wave transceiver replaces forward relay that shortwave/ultrashort wave provided by the invention does not have letter communication automatic forwarding method and multifunctional equipment, make the fully independently automatic connected network communication of communication network of modulation system two classes different with working frequency range, the design feature of its multifunctional equipment is that the radio reception frequency output of a radio station receiver links to each other with the sender modulation input of another radio station or self radio station (to ultrashort wave) through voice-grade channel.Realize that with microphone the conversation of shortwave ultrashort wave chips in, also have the ultrashort wave multiple functions such as relaying, the automatic dialing interface of ultrashort wave, shortwave data transmission terminal interface of transferring automatically simultaneously.
Description
The invention provides a kind of shortwave (monolateral band, amplitude modulation, frequency modulation, continuous wave etc.) and automatic method and the multifunctional equipment of transferring of ultrashort wave (frequency modulation, phase modulation) radio communication.
Existing wireless retransmission technique generally adopts alien frequencies switching trunking method, form wireless transmitting system by built-up circuit and two transceivers, utilize interior mute control circuit of receiver or squelch circuit control audio to amplify the switch of controlling the other side's sender mutually that has or not of output signal, realize transmitting automatically communicating by letter.In these two transceivers, one one is the ultrashort wave transceiver, and another one is a short-wave transceiver.Because the short wave communication channel is a variable element channel, decline changes that big communication quality is relatively poor and fast, and therefore, the squelch control poor performance can not guarantee that generally shortwave/ultra short wave communication reliably transfers.
The circuit of monolateral band of existing shortwave and the automatic networking interface equipment of frequency modulation communication is to utilize the muting control signal of frequency modulation and shortwave single side-band receiver to finish networking, only has the single function of networking, can't solve transceiver and automatic dialing system, data transmission terminal machine interface problem, and when communication needs two external microphones.
The objective of the invention is to design a kind of simple, practical, be not subjected to short wave communication quality influence, the forwarding method and the multifunctional equipment of the shortwave that under any circumstance can both transmit reliably/ultrashort wave radio communication.
Forwarding method of the present invention is with a ultrashort wave (VHF, UHF) full duplex (alien frequencies duplex) transceiver, a short-wave transceiver adds interconnecting device composition shortwave/ultra short wave communication repeater system (as shown in Figure 1), utilizing the good squelch control characteristic of ultrashort wave full duplex transceiver to control ultrashort wave and short-wave transceiver alternately transmits and communicates by letter: when needs shortwave and ultrashort wave connected network communication, open the external modulation door of two voice-grade channels with the changer in artificial or the dialing auto-closing interconnecting device, and startup ultrashort wave sender work, when the short wave communication network subscriber board is posted a letter, the short-wave receiver machine receive radio reception behind the signal frequently the voice-grade channel external modulation door of signal in interconnecting device send into the modulation input modulation of ultrashort wave sender, send after the amplification; When ultra short wave communication network users platform is posted a letter, after the ultrashort wave receiver is received signal, the output signal control electronic switch of the squelch circuit of (or outer) cuts out the ultrashort wave sender in the receiver, open short wave transmitter work simultaneously, the radio reception of ultrashort wave receiver signal another voice-grade channel external modulation door in interconnecting device frequently sends after sending into the modulation of short wave transmitter modulation input, amplification.When the ultrashort wave user did not post a letter in the radio station, the squelch circuit output signal of ultrashort wave receiver control electronic switch was opened the work of ultrashort wave sender, closes short wave transmitter simultaneously, thereby realized that shortwave/ultrashort wave radio communication replaces forward relay automatically.
In order to realize transfer the automatically method of connected network communication of above-mentioned shortwave and ultrashort wave radio communication, the invention provides a kind of multi-functional automatic transfer equipment, it have shortwave and ultra short wave communication transfer automatically networking, the automatic forward relay of ultrashort wave, dialing interface passes interface, ultrashort wave/shortwave conversation with the shortwave number automatically, switching is chipped in and multiple function such as program control accordingly.This multifunctional equipment is made up of input/output interface circuit, switch control circuit and voice-grade channel circuit three parts, wherein, input/output interface circuit is by ultrashort wave full duplex transceiver interface, and ultrashort wave automatic dialing system interface, this machine microphone interface, short-wave transceiver interface and shortwave data transmission terminal machine interface constitute; Switch control circuit is made of stabilized voltage power supply, control switch, function indication, electronic switch and logical circuit; The voice-grade channel circuit is made of coupling circuit and external modulation door.There is one can open two voice-grade channel external modulation doors and start can being connected with logical circuit control corresponding input of ultrashort wave sender work in the control switch circuit by switch artificial or automatic dialing system control.Logic control circuit is a gate array GAL logical circuit.Have in the stabilized voltage power supply one make the short wave transmitter microphone lost efficacy, through the short-wave transceiver interface obtain the external modulation input can be by artificial or dial system the external modulation control power supply and the external modulation control mains switch of control automatically.
