Secondly, still can damage the antenna system in the dismantlement process, the antenna system impedance value after the change can not perfectly match with wireless communication equipment, influences wireless communication equipment's signal transmission and signal reception, has reduced the signal transmission effect.

And S105, if the consistency of the reflected signal and the reference signal is successfully verified, determining that the impedance value of the transmission line is matched with the signal parameter.
Specifically, according to the signal parameters of the wireless communication device, for example, the signal parameters of the wireless communication device are input at a human-computer interaction interface, or the signal parameters are directly obtained by connecting the wireless communication device. Two paths of signals are established by the same signal source, wherein one path is a reference signal, and the other path is a test signal, so that the wavelength, the frequency and the like of a reflected signal of an emission signal are consistent with those of the reference signal. Alternatively, the reference signal may be a slightly powered signal.
Optionally, before the reference signal and the test signal are established according to the signal parameter of the wireless communication device, the impedance value of the transmission line is set according to the signal parameter of the wireless communication device, so as to reduce the number of traversals and save time.
Furthermore, the test signal is sent to the transmission line of the antenna system and is sent out after the impedance value of the antenna system is adjusted, and the reflected signal of the test signal is transmitted to the wireless communication equipment all the way and is transmitted to the antenna debugging equipment all the way after the impedance value of the transmission line is adjusted, so that the influence degree of the reflected signal on the wireless communication equipment can be obtained by testing the intensity of the reflected signal.
Optionally, the consistency check of the reflected signal and the reference signal may be to perform spectrum analysis on the reflected signal and the reference signal, or to directly coincide the reflected signal and the reference signal, so as to determine whether the consistency check of the reflected signal and the reference signal is successful according to a coincidence degree.

Wherein, human-computer interaction interface can also set up warning light, warning sound etc. for remind operating personnel.
The method comprises the steps of establishing a reference signal and a test signal according to signal parameters of the wireless communication equipment, sending the test signal and receiving a reflection signal of the test signal, further, carrying out consistency check on the reflection signal and the reference signal, and if the consistency check on the reflection signal and the reference signal is successful, determining that the impedance value of the transmission line is matched with the signal parameters. Therefore, the impedance value of the transmission line can be conveniently debugged on site, the installation environment which is too critical in construction is avoided, the antenna system does not need to be repeatedly installed and disassembled, the human resources and time are saved, and the impedance value of the antenna system can be conveniently adjusted. In addition, the impedance value of the transmission line can be perfectly matched with the wireless communication equipment, and the signal transmission effect of the wireless communication equipment is improved.
In one possible implementation manner, the performing consistency check on the reflected signal and the reference signal includes:
performing phase shift modulation on the reflected signal according to the phase difference between the reflected signal and the reference signal so as to enable the reflected signal and the reference signal to be in phase;
calculating the difference value of the reflected signal after phase shift modulation and the reference signal;

and if the difference value of the reflected signal after the phase shift modulation and the reference signal is within a preset threshold range, determining that the consistency check of the reflected signal and the reference signal is successful.
Fig. 2 is a flow chart illustrating another method of antenna tuning according to an example embodiment. As shown in fig. 2, the method includes:
s201, establishing a reference signal and a test signal according to signal parameters of wireless communication equipment, wherein the reference signal and the test signal are established according to the same signal source.
And S202, sending the test signal.
And S203, receiving the reflected signal of the test signal.
S204, according to the phase difference between the reflected signal and the reference signal, performing phase shift modulation on the reflected signal so as to enable the reflected signal and the reference signal to be in the same phase.
S205, calculating the difference value between the reflection signal after phase shift modulation and the reference signal.
S206, if the difference value of the reflected signal after the phase shift modulation and the reference signal is within a preset threshold range, determining that the consistency check of the reflected signal and the reference signal is successful.
In particular, the reflected signal is phase-shifted modulated according to the phase difference between the reflected signal and said reference signal, e.g. typically the reflected signal is delayed from the reference signal, the reflected signal is adjusted forward by the phase difference between the reflected signal and said reference signal. Illustratively, the phase difference between the reflected signal and the reference signal is 90 °, i.e., the reflected signal lags the reference signal by 90 °, then the reflected signal is adjusted forward by one quarter of a cycle, depending on the signal cycle, so that the reflected signal is in phase with the reference signal.
After the reflected signal and the reference signal are in phase, a difference value can be directly obtained between the reflected signal and the reference signal, and if the difference value between the reflected signal after phase shift modulation and the reference signal is within a preset threshold range, it is determined that the consistency verification is successful on the reflected signal and the reference signal. For example, if the time is the same, the reflected signal is greater than the reference signal, that is, the difference between the reflected signal and the reference signal is 5, and the positive value is smaller than the preset threshold 6, it is determined that the consistency check is successful on the reflected signal and the reference signal. For another example, if the time is the same, the reflected signal is smaller than the reference signal, that is, the difference between the reflected signal and the reference signal is-5, and the positive value is greater than a preset threshold value of-6, it is determined that the consistency check of the reflected signal and the reference signal is successful.
Optionally, an absolute value of a difference between the reflected signal and the reference signal may be checked, and if the absolute value of the difference is smaller than a threshold, it is determined that the consistency check of the reflected signal and the reference signal is successful.
By the above method, the consistency between the reflected signal and the reference signal can be determined to determine whether the impedance value deviation of the transmission line satisfies the signal parameter of the wireless communication device.
In another possible implementation manner, the performing consistency check on the reflected signal and the reference signal includes:
filtering the reflected signal to obtain a target signal;
and carrying out consistency check on the target signal and the reference signal.

s301, establishing a reference signal and a test signal according to signal parameters of the wireless communication equipment, wherein the reference signal and the test signal are established according to the same signal source.
And S302, sending the test signal.
And S303, receiving the reflected signal of the test signal.
S304, filtering the reflected signal to obtain a target signal.
S305, carrying out consistency check on the target signal and the reference signal.
S306, if the consistency of the reflected signal and the reference signal is successfully verified, determining that the impedance value of the transmission line is matched with the signal parameter.
Specifically, since the reflected signal of the test signal is reflected by another object, another signal may be mixed, and when the consistency check is performed on the reflected signal and the reference signal, the mixed other signal may affect the check result, so that the reflected signal may be subjected to processing such as filtering in advance, the filtering processing is performed to obtain the target signal, and the consistency check is performed on the target signal and the reference signal.
For example, a signal a is received, a reflected signal of an actual test signal is a signal B, the signal a further includes a signal C in addition to the signal B, and when the signal C is used for verifying the consistency of the signal B and a reference signal, the signal B is interfered, so that the verification result is not accurate enough. If the signal C improves the consistency between the signal B and the reference signal, the signal B may affect the communication performance of the wireless communication device, and if the signal C reduces the consistency between the signal B and the reference signal, the number of times of adjusting the impedance value may increase, which may increase the data size of the debugging, thereby affecting the debugging efficiency.
Optionally, the matching of the impedance value of the transmission line with the signal parameter means that the impedance value including the phase parameter and the capacitance parameter of the transmission line is matched with the signal parameter.
Specifically, the impedance value of the transmission line is provided by the phase parameter module and the capacitance parameter module of the transmission line, the impedance value of the transmission line is matched with the signal parameter of the wireless communication device, that is, the reflected signal processed by the phase parameter module and the capacitance parameter module of the transmission line has a small influence on the wireless communication device, and the phase parameter module and the capacitance parameter module of the transmission line can normally send and receive signals without influencing the normal communication of the wireless communication device.
Optionally, before the establishing the reference signal and the test signal according to the signal parameter of the wireless communication device, the method further includes:
and setting the phase parameter and the capacitance parameter according to the signal parameter of the wireless communication equipment.
Optionally, fig. 4 is a flowchart illustrating another antenna tuning method according to an exemplary embodiment. As shown in fig. 4, the method further comprises:
s401, if the consistency of the reflected signal and the reference signal is not successfully verified, adjusting the transmission line phase parameter and/or the transmission line capacitance parameter.
S402, receiving a first reflection signal of the test signal.
And S403, performing consistency check on the first reflection signal and the reference signal.
S404, if the consistency of the first reflection signal and the reference signal is successfully verified, the impedance value of the transmission line after adjustment is determined to be matched with the signal parameter.
Specifically, if the transmission line phase parameter and the transmission line capacitance parameter set according to the signal parameter of the wireless communication device cannot provide a good impedance deviation value, so that the impedance value of the antenna system is well matched with the wireless communication device, the transmission line phase parameter and/or the transmission line capacitance parameter is/are adjusted. For example, the phase parameter is increased to receive the first reflection of the test signal, or the capacitance parameter is increased to receive the first reflection of the test signal. It should be noted that the means for providing the phase parameter may be a variable phase adjustment module, and the means for providing the capacitance parameter may be a variable capacitor. Adjusting the impedance value of the antenna system may be achieved using electromechanical or microelectromechanical systems.
Further, consistency check is carried out on the first reflection signal and the reference signal, and after the check is successful, the impedance value of the transmission line after adjustment is determined to be matched with the signal parameter.
Therefore, the impedance value of the antenna system can be repeatedly adjusted, so that the impedance deviation value and the wireless communication equipment can achieve a better matching degree, and the communication effect of the wireless communication equipment is further improved. In addition, the adjustment process is fully automatic, the operation is simple, and the impedance value of the antenna system can be conveniently adjusted.
