It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the following description will be made by way of specific embodiments with reference to the accompanying drawings.
Fig. 1 is a flowchart of an implementation of a method for automatically aligning antennas of a beyond-view wireless communication system according to an embodiment of the present invention, where the method includes a master end antenna and a slave end antenna, and the master end antenna and the slave end antenna are opposite end antennas, and the method for automatically aligning antennas of a beyond-view wireless communication system may include: coarse alignment, frequency correction, synchronization, timing correction, fine alignment, initial communication verification and other steps are described in detail as follows:
Step 101, the main control end antenna and the subordinate control end antenna respectively determine the initial azimuth angle of the local end according to the longitude and latitude of the opposite end and the longitude and latitude of the local end, and control the local end antenna to turn to the determined initial azimuth angle.
Optionally, the coarse alignment stage includes calculating an initial azimuth from the longitude and latitude of the two ends of the communication. In this step, the main control end antenna and the subordinate control end antenna determine an initial azimuth angle of the local end according to the longitude and latitude of the opposite end and the longitude and latitude of the local end, and control the local end antenna to turn to the determined initial azimuth angle, which may include:
the main control end antenna and the subordinate control end antenna obtain longitude and latitude height information and direction angle information of the local end according to the Beidou of respective positioning and orientation; the main control terminal antenna and the subordinate control terminal antenna respectively send Beidou messages to the opposite terminal, wherein the Beidou messages comprise longitude and latitude height information of the local terminal; after the main control terminal antenna and the subordinate control terminal antenna respectively receive Beidou messages of the opposite terminal, calculating to obtain an initial azimuth angle of the local terminal according to longitude and latitude height information of the opposite terminal, longitude and latitude height information and azimuth angle information of the local terminal; the main control end antenna and the subordinate control end antenna respectively control the local end antenna controller to turn the antenna azimuth to the initial azimuth position corresponding to the local end.
In the process of transmitting the Beidou messages by the master control end antenna and the slave control end antenna, the sequence of transmitting the messages is not limited, and the master control end antenna can transmit to the slave control end antenna first, or the slave control end antenna can transmit to the master control end antenna first.
Step 102, the main control end antenna and the subordinate control end antenna detect signal intensity through single carrier signals at corresponding initial azimuth angles, and meanwhile, a first pitching angle pre-scanning is adopted, and according to the received single carrier signal intensity, the coarse alignment angle of the antennas is determined and a communication control link is started to be established.
The coarse alignment stage also includes pre-scanning the search signal by pitch angle at both ends. And after the initial azimuth angles of the two ends are determined, the two ends are respectively rotated to the initial azimuth angle positions determined by the two ends to perform coarse alignment of the pitch angle.
Optionally, in this step, at the corresponding initial azimuth angles of the master control end antenna and the slave control end antenna, signal strength detection is performed through a single carrier signal, and meanwhile, a first pitching angle is adopted for pre-scanning, and according to the received single carrier signal strength by comparison, a coarse alignment angle of the antennas is determined, and a communication control link is started to be established, which may include:
the main control end antenna sends a first single carrier signal to the subordinate control end antenna and scans by adopting a first pitching angle, and meanwhile the subordinate control end antenna scans by adopting the first pitching angle and searches for the first single carrier signal; if the slave control end antenna captures a first single carrier signal, performing frequency calibration; the slave control end antenna stops scanning after the frequency calibration is completed, and sends a second single carrier signal to the master control end antenna; and if the main control end antenna captures the second single carrier signal, performing frequency calibration, stopping scanning after the frequency calibration is completed, and sending a synchronous signal to the subordinate control end antenna so as to realize the initial synchronization of the main control end antenna and the subordinate control end antenna, and starting to establish a communication control link.
Optionally, when the master control end antenna sends the first single carrier signal to the slave control end antenna and performs the first pitching angle pre-scanning, the residence time of the master control end antenna at each standing point is the time of the slave control end antenna adopting the first pitching angle to pre-scan for one period, and enough time is reserved for the slave control end antenna, so that the full coverage of each standing point scanning of the slave control end antenna is ensured, the first single carrier signal sent by the master control end antenna is prevented from being unsuccessfully scanned due to missing scanning points, and the success rate of signal capturing is ensured.
Optionally, when the slave-end antenna performs the first pitch angle pre-scanning and searches for the first single carrier signal, the residence time of the slave-end antenna at each residence point is 1/n of the residence time of the master-end antenna at each residence point, where n represents the residence number of the slave-end antenna performing the first pitch angle pre-scanning.
It should be noted that, the main control end antenna needs to continuously transmit the first single carrier signal and the pre-scan until the second single carrier signal transmitted by the sub control end antenna is scanned and frequency calibration is completed, and then stops, and transmits a synchronization signal to the sub control end antenna to perform time domain synchronization.
The first single carrier signal and the second single carrier signal may be the same single carrier signal, and herein the terms "first" and "second" are used for distinguishing between the antenna ends transmitting the single carrier signals.
Optionally, the frequency calibration is a frequency calibration stage, when the master control end antenna and the slave control end antenna receive the single carrier signal sent by the opposite end, the received single carrier information is subjected to FFT (fast Fourier transform), so that the frequency domain error caused by clock deviation of the system is eliminated, and the frequency calibration is completed.
Optionally, the synchronization stage completes time domain synchronization of the master control end antenna and the slave control end antenna through the synchronization signal, so that the master control end antenna and the slave control end antenna can establish a basic communication control link.
Optionally, after the slave-end antenna stops scanning after the frequency calibration is completed and sends the second single carrier signal to the master-end antenna, the method further includes:
setting an overtime time;
when the slave-end antenna does not receive the synchronous signal sent by the master-end antenna within the timeout time, the master-end antenna is not successfully frequency-calibrated, and the step of jumping to the slave-end antenna to perform the first pitching angle pre-scanning and searching for the first single carrier signal is executed.
It should be noted that 1) if the first single carrier signal is successfully captured and frequency calibration is completed in the pitching pre-scanning process of the slave-end antenna, the slave-end antenna immediately stops pitching scanning and transmits the second single carrier signal to the master-end antenna, and the master-end antenna can complete frequency calibration with high probability at the moment due to certain symmetry of the channel. 2) The setting of the timeout time is that the slave-end antenna counts 30 seconds from the completion of frequency calibration, if the master-end antenna synchronization signal is not received in 30, the slave-end antenna considers that the timeout is considered, the slave-end antenna stops sending the second single carrier signal to restart pitching pre-scanning, and the pitching pre-scanning state of the master-end antenna is kept unchanged. This process loops until the system successfully enters the synchronization phase.
Optionally, at the corresponding initial azimuth angles, the main control end antenna and the subordinate control end antenna detect signal intensity through a single carrier signal, and simultaneously adopt a first pitching angle pre-scan, determine a coarse alignment angle of the antennas according to the received single carrier signal intensity by contrast, and after starting to establish a communication control link, the method further comprises the following steps:
the master control end antenna sends a timing instruction to the slave control end antenna, wherein the timing instruction comprises timing time; after receiving the timing instruction, the slave-end antenna feeds back to the master-end antenna; when the time correction time arrives, the master control end antenna and the slave control end antenna respectively clear the cyclic second timer.
The timing time is controlled by the antenna of the main control end, the whole interaction process is ensured to be completed within 1 second, and after the timing interaction is completed, the two ends are respectively cleared to the circulation second timer, so that time reference is provided for the subsequent link control instruction.
When the antenna coarse alignment is carried out, the application does not depend on an elevation map, and by adopting an initial pitch angle pre-scanning method, the application gets rid of the dependence on the elevation map when the beyond-line-of-sight wireless directional communication system is opened, and improves the coarse alignment efficiency. After the timing phase is completed, the communication control link is established, but the antennas at the two ends are not at the optimal communication angle, and the antenna fine alignment phase needs to be entered.
Step 103, after the primary control end antenna and the secondary control end antenna complete initial synchronization, the primary control end antenna and the secondary control end antenna interact through synchronization signals on a communication control link, and meanwhile, a second pitching angle fine scanning is adopted, and the antenna fine alignment angle is determined according to measurement of the signal median of the received synchronization signals.
The second pitch angle search range is smaller than the first pitch angle search range to perform fine scanning in a smaller range.
And in the antenna fine alignment stage, a granularity scanning method is adopted to resist channel fading interference, so that accurate measurement of a median value of received signals under fading channel conditions is realized, and accurate and reliable antenna automatic alignment of a wireless communication system is realized.
Optionally, in this step, after the primary synchronization is completed by the primary control end antenna and the secondary control end antenna, the primary control end antenna and the secondary control end antenna interact through synchronization signals on the communication control link, and simultaneously, a second pitch angle fine scanning is adopted, and an antenna fine alignment angle is determined according to measurement of a signal median of the received synchronization signals, including:
after the main control end antenna sends a pitching fine scanning instruction to the subordinate control end antenna through a communication control link, continuously sending a synchronous signal; after receiving the pitching fine scanning instruction, the slave-end antenna performs fine scanning by adopting a second pitching angle at all standing points, and after scanning is completed, determining the position of the median maximum point of the synchronous signals received in all the standing points as the pitch angle position of the slave-end antenna; the slave control end antenna is switched to the determined pitch angle position, and pitch fine scanning completion information is sent to the master control end antenna; after the main control end antenna receives the pitching fine scanning completion information, the pitching angle position of the main control end antenna is determined in the same mode that the subordinate control end antenna determines the pitching angle position; the antenna of the main control end is switched to the determined pitch angle position; the main control end antenna and the subordinate control end antenna adopt a pitch angle position determining mode to determine azimuth angles; and after the azimuth angle is determined, finishing the antenna angle fine alignment.
It should be noted that, the first pitch angle and the second pitch angle are both within a preset scanning range.
Optionally, signal fading phenomenon commonly exists in the beyond-view wireless communication system, and the signal fading phenomenon can be classified into fast fading and slow fading according to the length of a fading period, and the signal fading phenomenon has different statistical rules, and the antenna is mainly influenced by fast fading interference in an automatic antenna alignment process, so that the receiving level under the current antenna angle is estimated inaccurately, and the antenna alignment effect is poor. The median value of the received signal is an important index for measuring the intensity of the received signal, and can be used as a judgment standard of the size of the received signal.
In the process of acquiring the median value of the signals by the antenna alignment, the antenna signal acquisition time is theoretically at least longer than one fast fading period. Meanwhile, it should be noted that if the signal acquisition contains fewer fading cycles, there is interference of the sampled signal less than one complete cycle when the average power of the signal is calculated, so that a larger error exists in the calculated median of the signal. Therefore, when the median value of the signal in a short time under a certain antenna attitude is acquired, the more signal samples are collected in a certain time interval, the more accurate the estimation of the median value of the signal is. But the longer the signal is acquired, the less efficient the antenna alignment is, and thus the time consuming problem of antenna alignment needs to be measured simultaneously. The signal sampling period is not preferably less than 30 fast fading periods when the antenna is aligned.
In fine scanning, the dwell time of each dwell point is x seconds, the interval of each point is y degrees, and z points are scanned altogether. If the maximum point of the signal value in the z points is at the middle part, returning the antenna angle to the maximum point position after the scanning is finished; if the maximum point of the signal median among the z points is at the boundary, one point is further extended to the direction, and then the signal median results are compared, and the like.
And determining the position of the median maximum point of the synchronous signals received in all the resident points as the pitch angle position of the slave-end antenna, wherein the method comprises the following steps:
if the median maximum point of the synchronous signals received in all the standing points is located at the middle position of all the standing points, determining the position of the median maximum point as the pitch angle position of the slave-end antenna;
if the median maximum point of the synchronous signals received in all the resident points is located at the boundary position of all the resident points, expanding one resident point towards the boundary direction of all the resident points, comparing the signal median value of the expanded resident point and the current signal median maximum point until the determined position of the signal median maximum point is not located at the boundary position of all the resident points, and taking the position of the current median maximum point as the pitch angle position of the subordinate control terminal antenna.
After the antennas are precisely aligned, the antennas at the two ends are at the optimal communication angle, at the moment, the communication control link state after the antennas are precisely aligned can be confirmed through initial communication verification, the antennas at the two ends judge the link state through detecting the verification result of the communication at the local ends, if the antennas at the two ends are correctly verified in a certain observation window, the communication link is confirmed to be successfully opened, otherwise, the current communication link is insufficient to support the operation of the service, and the antennas at the two ends are re-aligned.
According to the method for automatically aligning the antennas of the beyond-view wireless communication system, the signals are captured in the pitching pre-scanning mode in the coarse alignment stage, the requirement on a storage space is reduced without depending on an elevation map, the residence time of the pre-scanning residence point is determined according to the distinction between the main control end antenna and the subordinate control end antenna, the full coverage of each scanning point of the main control end antenna and the subordinate control end antenna is ensured, and the success rate of signal capturing is ensured. Adopting a granularity scanning method in the fine alignment stage, covering a certain number of fading cycles through signal statistics of fixed positions, and ensuring the accuracy of receiving level estimation; the signal median is used as a measurement index of the received signal strength, so that measurement deviation caused by special sampling points can be avoided, the accuracy and reliability of signal detection are ensured, and the antenna alignment accuracy is improved. The scheme can realize automatic alignment of the antenna, really realize one-key opening and improve the alignment efficiency of the antenna.
It should be understood that the sequence number of each step in the foregoing embodiment does not mean that the execution sequence of each process should be determined by the function and the internal logic, and should not limit the implementation process of the embodiment of the present invention.
