Before the fault detection method provided by the application is described in detail, related elements, application scenes and implementation environments related to the application are simply described.
Phased array antenna
Phased array antennas have evolved from array antennas, relying primarily on phase changes to effect movement or scanning of the antenna beam pointing in space, also known as Electronic Scanning Array (ESA) antennas. The antenna elements may be individual waveguide horns, dipoles, patch antennas, etc.
A phase shifter is provided at the rear end of each antenna element for changing the phase relationship of the signals between the elements, the amplitude variation of the signals being achieved by a power splitting/summing network or an attenuator.
Linear phased array antenna scanning principle
Linear phased array antennas are widely used in phased array radars for one-dimensional phased scanning. Linear phased array antennas can be divided into broadside and end-fire arrays, depending on the basic array type.
The maximum radiation direction of the vertical array is perpendicular to the array axial direction, and the antenna beam scans left and right sides of the linear array normal direction. Instead, the end-fire array main lobe direction is along the array axis. The antenna beam maximum pointing can be changed by changing the intra-array phase shift values between adjacent elements in the array.
Planar phased array antenna scanning principle
The planar phased array antenna refers to an array antenna in which antenna units are distributed on a plane, and antenna beams can be scanned in a phased manner in both azimuth and elevation directions.
The arrangement modes of the planar phased array antenna units mainly comprise two types: rectangular lattice arrangement and triangular lattice arrangement, the latter can be seen as being made up of two planar phased array antennas arranged in a rectangular lattice with a larger cell spacing.
Basic constitution of phased array antenna
Phased array antennas vary widely in circuit design, structural form, microwave elements, control methods, and the like. In general, a phased array antenna is composed of an antenna array plane, a phase shifter, a feeder line network, a corresponding control circuit and the like.
A passive phased array antenna is one if the feed network of the phased array antenna does not contain active circuitry. An antenna is referred to as an active phased array antenna if each element path of the antenna contains active devices, such as signal power amplifiers, low noise amplifiers, mixers, etc.
Antenna array surface
Phased array antenna arrays are typically made up of hundreds to tens of thousands of unequal phase-controlled channel excitation radiating elements. These radiating elements may be individual waveguide horns, dipoles, patch antennas, etc.
When these radiating elements are distributed on a plane, they are called planar phased array antennas; distributed on a curved surface, called a curved surface phased array antenna; if the curved surface conforms to the shape of the radar mounting platform, then a conformal phased array antenna is formed.
Feeder network
Phased array antennas are a multi-channel system, typically comprising a large number of antenna elements, with a multiple feed network between the transmitter, receiver and antenna array elements.
The process of delivering signals to each radiating element in the antenna array plane through the transmitter output or delivering signals received by each radiating element in the antenna array plane to the receiver input is referred to as feeding, and the phase distribution required to provide the individual antenna element channels in the array to achieve beam scanning or change beam shape is referred to as feeding.
Phase shifter
Various types of phase shifters are key devices for realizing phase feeding of a phased array antenna feeder network, and requirements for the phase shifters are that: the phase shift value is accurate and the performance is stable; broadband and high-power capacity; and the rapid control is convenient.
Phase shifters are largely divided into two categories, field Effect Transistor (FET) analog phase shifters using voltage-controlled varactors and pass digital phase shifters using PIN diodes as switching devices.
The common planar array has some basic types, and the following division can be performed according to a grid form: rectangular grids, triangular grids, concentric circular rings, elliptical ring grids and the like; the following divisions may be made in boundary form: rectangular, hexagonal (rectangular chamfer forming), circular, oval, etc.
The appearance of the planar array formed by the rectangular grid and the triangular grid can be rectangular, hexagonal, circular and the like. The planar array of the triangular grid arrangement needs less units under the condition of meeting the same antenna index. The sidelobe levels of uniformly distributed circular planar arrays and hexagonal arrays are lower than those of planar rectangular arrays. And hollowing out the middle array element of the planar array to form a hollow planar array for placing other devices or arrays, wherein hollowing out the middle element can cause the side lobe level of the array antenna pattern to be raised.
For example, a uniformly distributed circular planar array of cell numbers 1264 is shown in FIG. 1.
With the development of communication technology, the future mobile communication technology (e.g., 6G) uses array antennas in a large amount.
However, the array antenna has the problems of large volume, inconvenient carrying and installation, and the like. Particularly for low frequency bands, the array antenna is large in size and particularly inconvenient, and is subject to many limitations in some extreme communication scenarios, such as space-to-ground communication scenarios.
In view of the above problems, the present application provides a communication method applied to a base station including a strip-shaped baseband board; an antenna oscillator is arranged on the strip-shaped baseband board; a strip baseband board rotates through a center point of the strip baseband board, the communication method comprising: acquiring a rotation period and a rotation angular velocity of the strip-shaped baseband board; acquiring the distance between the antenna element and the center point and the rotation time of the antenna element; determining the position of the antenna element according to the rotation period, the rotation angular velocity, the distance and the rotation time; and processing the communication signal according to the position of the antenna element.
Therefore, the method can replace the circular array with the strip-shaped baseband board which is rotatable and is convenient to install, transport or carry, and reduces the difficulty of installation and carrying. Secondly, since each antenna element on the plane formed by the rotated strip-shaped baseband board is actually in a time-sharing manner, the application can acquire the rotation period and rotation angular velocity of the strip-shaped baseband board, the distance between the antenna element and the center point and the rotation time of the antenna element, and determine the position of the antenna element according to the rotation period, the rotation angular velocity, the distance and the rotation time. Thus, the communication signals can be processed according to the positions of the antenna elements, and the array antenna communication is realized.
The communication method is suitable for the base station. Fig. 2 shows a structure of the base station. As shown in (a) of fig. 2, the base station includes: antenna, feeder, base station, holding pole, antenna adjustment support etc.. The antenna is used for converting radio frequency signals of the base station into electromagnetic waves and radiating the electromagnetic waves in a specific mode and direction, or converting the received electromagnetic waves into radio frequency signals and feeding the radio frequency signals back to the base station through a specific channel, and the antenna comprises a feed network for providing radio frequency energy for a radiating unit in the antenna. The feed lines are used for connecting the antennas with the base station and also for connecting the radiating elements with a feed network (not shown in the figure). The base station is used for processing baseband and radio frequency signals, providing channels and system capacity, and realizing uplink and downlink communication functions. The holding pole is used for supporting the antenna. The antenna adjusting bracket is used for fixing the antenna and adjusting the beam declination angle of the antenna so as to adjust the coverage area of the beam.
The antenna may include an antenna array composed of a plurality of antenna elements (which may also be referred to as antenna elements). As shown in (b) of fig. 2, the antenna element may be fixed to a strip-shaped baseband board, that is, the antenna element is mounted on the strip-shaped baseband board. The strip baseband board may be rotated by a center point of the strip baseband board.
Alternatively, the base station may be a base station or a base station controller for wireless communication, or the like. In the embodiment of the present application, the base station may be a base station (base transceiver station, BTS) in a global system for mobile communications (global system for mobile communication, GSM), a base station (base transceiver station, BTS) in a code division multiple access (code division multiple access, CDMA), a base station (node B) in a wideband code division multiple access (wideband code division multiple access, WCDMA), a base station (eNB) in an internet of things (internet of things, ioT) or a narrowband internet of things (NB-IoT), a base station in a future 5G mobile communication network or a future evolved public land mobile network (public land mobile network, PLMN), which is not limited in this embodiment of the present application.

The processor 21, when calling and executing instructions or program code stored in the memory 22, is capable of implementing the communication method provided in the following embodiments of the present application.
In the embodiment of the present application, the software program stored in the memory 22 is different for the base station, so the functions realized by the base station are different.

It should be noted that the structure shown in fig. 3 (or fig. 4) does not constitute a limitation of the communication apparatus, and the communication apparatus may include more or less components than those shown in fig. 3 (or fig. 4), or may combine some components, or may be arranged in different components.
The following describes in detail the communication method provided by the embodiment of the present application with reference to the accompanying drawings.
The communication method provided by the embodiment of the application is applied to the base station in the communication system shown in fig. 2 and is applied to the base station comprising the strip-shaped baseband board; an antenna oscillator is arranged on the strip-shaped baseband board; the strip-shaped base band plate rotates through the center point of the strip-shaped base band plate. As shown in fig. 5, the communication method provided by the embodiment of the present application includes:
s501, the base station acquires the rotation period and the rotation angular velocity of the strip-shaped baseband board.
Specifically, because the array antenna has the problems of large volume, inconvenient carrying and installation and the like, the base station provided by the embodiment of the application can comprise a strip-shaped baseband board.
That is, after the antenna element is mounted on the strip-shaped baseband board with a smaller area, the strip-shaped baseband board can continuously rotate at a constant speed to form a plane, so that the space diversity of the array antenna is increased. However, each antenna element on the plane formed by the rotated antenna is actually time-shared, and therefore, when determining the position of the antenna element, the base station needs to algorithmically superimpose a time function.
In this case, the base station can acquire the rotation period and the rotation angular velocity of the strip-shaped baseband board.
Alternatively, the rotation period may be the time taken for the strip baseband plate to rotate once, for example, 10 seconds for the strip baseband plate to rotate once. The rotational angular velocity refers to the angle of rotation per unit time when an object rotates around a certain axis. In the embodiment of the application, in order to increase the space diversity of the array antenna, the strip baseband board generally takes the center point of the strip baseband board as a rotation point. In this case, the precession angular velocity is an angle of rotation per unit time when the strip-shaped base band plate rotates at the center point of the strip-shaped base band plate.
S502, the base station obtains the distance between the antenna element and the center point and the rotation time of the antenna element.
Specifically, a plurality of antenna elements can be uniformly mounted on the strip-shaped baseband board. In order to accurately determine the position of the antenna element, the base station may acquire the distance between the antenna element and the center point, and the rotation time of the antenna element.
For example, when the position of the antenna element at the current time needs to be determined, the base station may acquire the current time, the distance between the antenna element and the center point, and the rotation time of the antenna element from the beginning rotation time to the current time.
S503, the base station determines the position of the antenna element according to the rotation period, the rotation angular velocity, the distance and the rotation time.
In some embodiments, in S503, the method for determining the position of the antenna element by the base station according to the rotation period, the rotation angular velocity, the distance, and the rotation time specifically includes:
and the base station determines the rotation time of the antenna element in the current rotation period according to the rotation period and the rotation time.
And the base station determines the position of the antenna element according to the rotation duration, the rotation angular velocity and the distance. The position of the antenna element comprises an abscissa X and an ordinate Y. The abscissa X and the ordinate Y satisfy the following formula:
X＝R*cos(ω*t)；
Y＝R*sin(ω*t)；
wherein R is distance, ω is rotational angular velocity, and t is rotational duration.
Specifically, when the base station determines the position of the antenna element according to the rotation period, the rotation angular velocity, the distance and the rotation time, it can be regarded as algorithmically superimposing a time function. The time function is that the corresponding relation between the antenna element in rotation and the element of the virtual plane array antenna changes with time.
Illustratively, taking a uniformly distributed circular planar array of cell numbers 1264 as an example, the radius of the circle of the planar array is 1000 millimeters, one antenna element is mounted within one square of 50 millimeters by 50 millimeters, assuming an array center coordinate of (0, 0).
For a substrate length of 2000 mm, the rotation center selects a rotation antenna at the center point, and assuming that the angular speed of rotation of the antenna is ω, the position of the antenna unit at the radius R on the rotation antenna satisfies the trigonometric function relationship, that is, the position of the antenna element includes an abscissa X and an ordinate Y, which satisfy the trigonometric function relationship.
The abscissa X and ordinate Y may vary continuously periodically, overlapping the antenna elements of the virtual planar array once per revolution.
Optionally, the standard for the base station to determine that the antenna element positions overlap may be set as follows: assuming that the center point coordinates of a certain cell on the planar array are (X0, Y0), then (X-X0)/(2+ (Y-Y0)/(2), i.e., the cell with the shortest center point distance is selected as the position overlapping cell.
In some embodiments, in S503, the method for determining the position of the antenna element by the base station according to the rotation period, the rotation angular velocity, the distance, and the rotation time specifically includes:
the base station inputs the rotation period, the rotation angular velocity, the distance and the rotation time into a pre-trained prediction model to obtain the position of the antenna element.
