Judged by the microcomputer in the power amplifier, if the ratio of forward and reverse detection voltage faces more than standing-wave ratio
Dividing value, 80C552 microcontrollers close the radio frequency amplifier excitation inside short-wave transceiver, and generate control and protection electricity accordingly
The protection information is sent to control box and shown by the corresponding protection information in road, and the mesh of protection short-wave radio set is reached with this
, and user's short-wave radio set is prompted to be in transmitting guard mode.
According to the inverse detection voltage set protection thresholding, the protection door be limited to the inverse detection voltage for P when
Sampling voltage, and detect backward voltage in real time；When the backward voltage detected is more than the sampling voltage, short-wave radio set opens
Dynamic protected mode.
Specifically, the setting for protecting thresholding is protection of the short-wave radio set to short-wave transceiver, is existed in power amplifier
Backward power is sampled in microcomputer, protection thresholding is set, which is arranged to the sampling when inverse detection voltage is P
Voltage, select the inverse detection voltage for P when sampling voltage be due to during short-wave radio set use radiofrequency signal it is anti-
Power is penetrated generally in 20W or so, the reflection power when inverse detection voltage is P leaves remaining to short-wave radio set normal transmission
Amount so that be not in frequent protection during short-wave radio set use；In addition during short-wave radio set use radiofrequency signal it is anti-

It is close to automatic antenna tune using ceramic skeleton, the ceramic skeleton inside automatic antenna tuner in the present embodiment
For balancing the internal heat of automatic antenna tuner, short-wave radio set is completed with this for the metal base plate of humorous device or surrounding frame
Transmitting protection.
Specifically, automatic antenna tuner completes short-wave transceiver and the resonance matching of aircraft antenna works, but described
After the completion of resonance matching work during transmitting high-power RF signal, automatic antenna tuner can be tuned in sampling microwave network and connect
The matching high-frequency inductor coil entered passes through high current so that automatic antenna tuner itself generates larger heat, and temperature drastically rises
Height in turn results in the good impedance parameter mismatch of initial resonance matching, and short-wave transceiver and short-wave antenna are detuning, short-wave antenna
The backward power of the radiofrequency signal of transmitting is more than 40W, and transmitting protection phenomenon occurs in short-wave radio set, therefore automatic antenna tuner is being set
Meter needs to consider high temperature resistant, the heat dissipation design of internal network.
Automatic antenna tuner completes short-wave transceiver and the resonance matching of short-wave antenna works, that is, automatic antenna
The tuning process of tuner, the automatic antenna tuner inside of the present embodiment include inductor, capacitor, standing-wave ratio detection electricity
Road；The inductor, capacitor and short-wave antenna composition matching network, the inductor and capacitor according to matching network tune
When humorous track access or disengaging matching network, the network state of matching network constantly changes, and standing-wave ratio detection circuit again will
It detects that the standing-wave ratio of real-time change gives microprocessor P89C51RD+, so constantly cycles, until short-wave radio set and shortwave day
Line realizes matching.
During actually tuning, the RF signal power detected is only 20W, and the radiofrequency signal of short-wave antenna transmitting
Power is maintained at more than 200W, and the matching network temperature of automatic antenna tuner occurs huge after continuous wave high power emits 5min
Change, the corresponding magnitude of inductor and capacitor used in matching network, which is affected by temperature hair respectively, to be changed so that
Short-wave radio set and short-wave antenna matching status are detuning.
For a long time during transmitting high-power RF signal, automatic antenna tuner persistently generates heat, but due to increasing
The ceramic skeleton added is close to the metal base plate of automatic antenna tuner or surrounding frame in installation process, can be ceramic skeleton
Heat be transmitted on the metal base plate or surrounding frame of automatic antenna tuner, reduce the internal network of automatic antenna tuner
Temperature, and then thermal equilibrium state do not interfere with the matching status of automatic antenna tuner and the power of short-wave radio set
Launch time.
A kind of transmitting guard method based on short-wave radio set of the present invention is more demanding to accuracy, and forward and reverse work(
Rate sampling is the basis of short-wave radio set transmitting protective device, therefore the component reliability in forward and reverse power sample circuit is higher than
The reliability of resistance, capacitance or integrated circuit；In addition, when setting protection threshold voltage, backward power must not be taken less than 40W
Otherwise power can frequently occur short-wave radio set transmitting guard mode, and then influence the normal use of short-wave radio set；When there is shortwave
It after radio station transmitting guard mode, also needs to check short-wave antenna, cable, because the short-wave antenna of damage, cable equally can
There is short-wave radio set transmitting guard mode, can release short-wave radio set by the operation of control box emits guard mode.Therefore, automatically
After antenna tuner considers high temperature resistant, heat dissipation, it is also necessary to the installation of increased ceramic skeleton, and when installing must and automatic antenna
The metal base plate or surrounding frame of tuner completely attach to.
The transmitting guard method based on short-wave radio set of the present invention is in mating Air Force-Navy 4-5 model of plant produced
The airborne short-wave radio sets of 200W are widely applied, and are largely equipped on series aircraft, are not used largely in data-link
In the case of, the protective device of short-wave radio set transmitting effectively solves short-wave antenna because of environmental factors such as ambient pressure, temperature
The variation of caused antenna parameter causes short-wave radio set detuning, and with short-wave radio set data-link large-scale use after, automatic day
The design protection of line tuner efficiently solve the problems, such as short-wave radio set for a long time, it is easily detuning after high-power transmitting.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
God and scope；In this way, if these modifications and changes of the present invention belongs to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these modification and variations.
