Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention
In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is
Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.
Embodiment one
Fig. 1 is please referred to, Fig. 1 is the flow chart for the process that a kind of antenna tuner provided by the invention accesses recognition methods,
This method includes：
Step s101：After the power is turned on, radio station sends the identification code of preset time with predeterminated frequency to attachment device in radio station；
It is understood that when whether pair attachment device being connect with radio station is that antenna tuner judges, first
It is powered on to radio station, the duplexer acquiescence on radio station is connected to narrow-band antenna pattern at this time, at this time the electricity of radio station and antenna tuner
Source disconnects.In addition, because do not know that the attachment device being connect with radio station is antenna tuner or broad-band antenna or tester
Device etc., therefore, after the power-up, radio station sends the identification code of preset time with predeterminated frequency to attachment device at once in radio station.
Wherein, predeterminated frequency here can be 76.8kHz, in fact, predeterminated frequency here is when being sent with radio station
The agreement used is related, that is to say, that the agreement that uses is different when radio station sends identification code, and predeterminated frequency here is not yet
Together, therefore, the present invention is not particularly limited the concrete numerical value of predeterminated frequency, is determined according to actual conditions.
In addition, preset time here is also artificially to be set by parameter, filled when being configured to preset time
Divide the initialization time of each unit for taking into account radio station when just powering on etc. so that attachment device can receive radio station hair
The identification code sent.
Step s102：When attachment device receives identification code, and identification code is handled to obtain identification conditioned signal, and will
Identification conditioned signal is sent to radio station；Radio station receives identification conditioned signal, and judges according to preset reference level and identification code
When identification conditioned signal meets default identification condition, radio station judges attachment device for antenna tuner；
Step s103：Radio station powers for antenna tuner.
It is understood that if attachment device receives identification code, and identification code is handled to obtain identification conditioning letter
Number, and identification conditioned signal is sent to radio station；Radio station receives identification conditioned signal, and according to preset reference level and identification
Code judges to identify whether conditioned signal meets default identification condition, if identification conditioned signal meets default identification condition, electricity
Platform can determine whether that the attachment device is exactly antenna tuner, and radio station will start power supply state, for antenna tuner power, radio station with
Antenna tuner carries out operating mode；Otherwise, radio station then judges that the attachment device is not antenna tuner, then radio station will be kept
In not power supply state.
The present invention provides a kind of antenna tuners to access recognition methods, and radio station after the power is turned on can be to the connection being connect with radio station
Device sends the identification code for being used for verifying identification, when attachment device receives identification code and identification code is handled to obtain identification tune
Signal is managed, and identification conditioned signal is sent to radio station, and radio station judges that identification is adjusted according to preset reference level and identification code
When reason signal meets default identification condition, then illustrate the attachment device for antenna tuner, radio station just starts to antenna tune at this time
The power supply of humorous device, it is seen then that radio station disclosed in the present application have automatic identification access attachment device whether be antenna tuner work(
Can, it avoids since maloperation prevents radio station to be in power supply state from normally connecting work with broad-band antenna or to other surveys
Test instrument damages or causes the damage of radio station associated components itself, improves the security performance of radio station power supply.
Embodiment two
Present embodiment discloses another antenna tuners to access recognition methods, and this method is on the basis of embodiment one：
Preferably, radio station is specially with the process of predeterminated frequency to the identification code of attachment device transmission preset time：

To feeder line, feeder line will identify that conditioned signal passes back to radio station.
Preferably, radio station receives identification conditioned signal, and judges identification according to preset reference level and identification code
When conditioned signal meets default identification condition, radio station judges that attachment device is specially for the process of antenna tuner：
The power-supply filter in radio station filters out the identification code on feeder line, and identification conditioned signal is only sent to the voltage in radio station
Comparator；
Voltage comparator will identify that conditioned signal and preset reference level are compared processing, obtain identification signal,
And identification signal is sent to the processing unit in radio station；
Identification signal is compared by processing unit with identification code, when comparison result meets default identification condition,
Then processing unit judges to obtain attachment device as antenna tuner.
It is understood that radio station is filtered out the identification code of the predeterminated frequency on feeder line by power-supply filter, will only know
Other conditioned signal is sent to the voltage comparator in radio station, and voltage comparator will identify that conditioned signal compares with preset reference level
Compared with obtaining identification signal.
Wherein, preset reference level here can be level only bigger than low level, therefore, if identification conditioning
Signal is square wave detection signal, then obtained identification signal remains square-wave signal.
Processing unit by be square-wave signal identification signal be also square-wave signal identification code be compared, when than
When relatively result meets default identification condition, then processing unit judges to obtain attachment device as antenna tuner.
It is worth noting that, it can be when identification signal and identification that comparison result here, which meets default identification condition,
The similarity of code meets certain threshold value, is also not necessarily limited to this certainly, is determined according to actual conditions.
Preferably, radio station is specially for the process of antenna tuner power supply：
Processing unit controls power-supply filter to be connect with power supply by first switch selecting unit, and power supply passes through power filter
Day tune control device power supply of the device for antenna tuner.
The present invention provides a kind of antenna tuners to access recognition methods, does not need to manually set radio station after use
It puts, it is only necessary to normally start radio station, in the case of physical connection day tune, radio station is connect automatically with day tune.In no day tune
In the case of, radio transmitter identification is not connected with day tune, and radio station delivery outlet does not export direct current signal, ensures the phase in the instrument and radio station of connection
Component is closed not damage.
