The voltage value of detected first coupled signal of device is 5V, which is compared by comparator with a preset voltage value,
If preset voltage value is 3V, the preset voltage value is determined according to the performance of the wave detector, comparator and receiver
, further, wave detector is detected to be also possible to a continuous parameter signal, such as continuous voltage signal, can basis
Actual conditions are arranged, and in these cases, the voltage value of the first coupled signal is greater than preset voltage value, that is to say, that first coupling
The power for closing signal is greater than the predetermined power of predeterminated voltage, at this point, the decision level of comparator output is high level, correspondingly,
Voltage value as wave detector detects the first coupled signal of acquisition is 1V, is less than preset voltage value, then, the function of the first coupled signal
Rate is less than the predetermined power of predeterminated voltage, at this point, the decision level of comparator output is low level, it is of course also possible to first
When the power of coupled signal is greater than the predetermined power of predeterminated voltage, comparator exports high level, in the power of the first coupled signal
Less than predeterminated voltage predetermined power when export low level, the application is not specifically limited.
Second of implementation

20 further include processing unit, is connected with the analog-digital commutator, and the processing unit is for judging first digital parameters
The second relationship between signal and a preset number parameter signal obtains the first judging result；When the first judging result table
First power of bright first signal is less than the signal input power of receiver 30, at this point, generating for characterizing described in connection
First processing result of the first access；When first judging result shows that first power is greater than the signal input work
Rate, at this point, generating for characterizing the second processing result for being connected to the alternate path.
Specifically, wave detector can be envelope detector, lock detector, it is also possible to other kinds of wave detector, this
Field technical staff can select according to actual needs, and detected first coupled signal parameter of wave detector can be electricity
Pressure, electric current or other parameters, in the embodiment of the present application, by taking the first coupled signal parameter is voltage as an example, such as electricity of acquisition
Pressure is 5V, by the processing of analog-digital commutator, exports the first digital parameters signal 1, for another example the detected voltage of wave detector
For U (t)=ACos (ω t), the first digital parameters signal 1011 is exported by the processing of analog-digital commutator.
Next, the first digital parameters signal is sent to the processing unit, the processing unit is for judging
The second relationship between the first digital parameters signal and a preset number parameter signal, second relationship can be to compare
Size between first digital parameters signal and preset number parameter signal, or whether judge the first digital parameters signal
Match with preset number parameter signal.In the embodiment of the present application, by taking whether processing unit detection parameters match as an example, locating
It can store a presets list in reason unit, the letter for being less than receiver with first the first power of signal be stored in the presets list
Digital parameters corresponding to number input power, and/or be stored with the signal for being greater than receiver with first the first power of signal and input
Digital parameters corresponding to power, as show in the presets list the first power be less than receiver input power digital parameters be
0001,0010, the digital parameters for showing that the first power is greater than receiver input power are 1001,1010, when processing unit receives
When the first digital parameters signal to analog-to-digital conversion is 0010,0010 is compared with the digital parameters in the presets list, institute
The first result Corresponding matching is stated as a result, by comparing, can determine 0010 it is corresponding be that the first power is less than receiver input work
Rate, i.e., first are the result shows that the first signal will not cause receiver to block.
In the specific implementation process, described control unit can be switch, and when switch is single control switch, at least one is logical
Road 40 and the connection type of antenna 10 are as shown in Figure 4 A, when switch is double control switch, at least one access 40 and antenna 10
Connection type is as shown in Figure 4 B, and certainly, those skilled in the art can select the type or choosing of switch according to the actual situation
Other control units are selected, as long as being able to achieve switched path, the application is not specifically limited.
For the first implementation, when comparator output low level shows that the power of the first coupled signal is less than default electricity
When the predetermined power of pressure, antenna 10 is then connected to the first access by the switch, and then antenna 10 is made to pass through first access
It is connected to the receiver；When comparator output high level shows that the power of the first coupled signal is greater than the default function of predeterminated voltage
When rate, antenna 10 is then connected to the alternate path by the switch, and then is connected to antenna 10 by the alternate path
The receiver
It is used for for second of implementation when the processing result of the processing unit is first processing result
Antenna 10 is connected to first access, and then antenna 10 is made to be connected to the receiver by first access；Or work as
When the processing result of the processing unit is the second processing result, for antenna 10 to be connected to the alternate path, into
And antenna 10 is made to be connected to the receiver by the alternate path.
Specifically, when comparator output low level shows that the power of the first coupled signal is less than the default function of predeterminated voltage
When rate or the processing result of processing unit are the first processing result, the interference signal that the first signal is included is not enough to cause
Receiver generates obstruction, at this point, not needing to be filtered the first signal, the first signal is directly sent to receiver,
Therefore, it switchs in this case by the first access connection, so that antenna is connected directly with receiver；When comparator exports high electricity
The processing result of predetermined power or processing unit that the flat power for showing the first coupled signal is greater than predeterminated voltage is second processing
When as a result, it is meant that the interfering signal power that the first signal is included will lead to by force very much receiver and generate obstruction, at this time, it may be necessary to right
First signal is filtered, and switchs alternate path connection, filter is connected into receiving path, so that the first signal passes through
Receiver is being sent to after crossing filtration treatment.
