[0052] Please refer to Figure 1 , Figure 1 A flow chart of a method for testing a magnetic levitation millimeter wave ground base station antenna provided by an embodiment of the present invention. The method comprises:
[0053] S110: Acquire positioning information collected by a positioning module in a millimeter wave test device; the millimeter wave test device includes multiple antennas and a positioning module;
[0054] It should be noted that the millimeter wave test device in the embodiment of the present invention is provided with multiple antennas and positioning modules, wherein each antenna constitutes an antenna array, and the antenna array constitutes a millimeter wave radio frequency receiving unit. In addition, the millimeter wave receiving unit in the millimeter wave test device may also include a receiving front end and a servo motor action unit. After the millimeter wave ground base station is fixed, a millimeter wave test device can be deployed on the center line of the high-speed maglev track, and the millimeter wave receiving unit of the millimeter wave test device can be kept horizontal with the on-board mobile base station of the high-speed maglev train.

For example, the positioning module is a GPS (Global Positioning System) module, and the collected positioning information is a GPS signal.
[0055] In practical applications, the outer shapes of the multiple antennas in the millimeter wave test device in the embodiment of the present invention are the same as the cross-sectional shape of the electromagnetic wave beam emitted by the ground base station. Specifically, the cross-sectional shape of the electromagnetic wave beam emitted by the ground base station is a rectangular cross-sectional shape. Please refer to Figure 2 The millimeter wave test device includes a central antenna (antenna 1) and four peripheral antennas (antenna 2 to antenna 5), the four peripheral antennas are distributed on different sides of the rectangle, the central antenna is located at the center of the rectangle, and the central antenna is connected to each peripheral antenna through a corresponding servo motor and a mechanical arm.

The millimeter wave receiving unit of the millimeter wave test device can be kept horizontal with the mobile base station on the high-speed maglev train through the antenna 1 supported by the rod-shaped structure.
[0057] S120: Determine a distance parameter of the millimeter wave test device relative to the ground base station according to the positioning information;
[0058] It can be understood that after obtaining the positioning information, the distance parameter of the millimeter wave testing device relative to the ground base station can be obtained according to the positioning information.
[0059] In one implementation, the process of determining the distance parameter of the millimeter wave testing device relative to the ground base station according to the positioning information in the above S120 may include:
[0060] Determine the vertical distance of the millimeter wave test device relative to the ground base station according to the positioning information;
[0061] Obtain the horizontal distance between the center of the ground base station and the center line of the track, the center height of the ground base station antenna and the height of the track surface;
[0062] Calculate the first horizontal distance between the first vertical side of the electromagnetic wave beam emitted by the ground base station and the center line of the track according to the vertical distance of the millimeter wave test device relative to the ground base station and the horizontal distance between the center of the ground base station and the center line of the track;
[0063] According to the vertical distance of the millimeter wave test device relative to the ground base station, the center height of the ground base station antenna and the height of the track surface, the second horizontal distance between the second vertical edge of the electromagnetic beam and the center of the track, the first vertical distance between the first horizontal edge of the electromagnetic beam and the center of the track, and the second vertical distance between the second horizontal edge of the electromagnetic beam and the center of the track are calculated.
[0064] It should be noted that, in the embodiment of the present invention, the vertical distance d1 (such as Figure 3 As shown in the figure), obtain the horizontal distance d2 between the center of the ground base station and the center line of the track (as shown in the figure Figure 4 As shown), the center height h2 of the ground base station antenna and the track surface height h1, and according to the vertical distance d1 of the millimeter wave test device relative to the ground base station and the horizontal distance d2 between the center of the ground base station and the center line of the track, calculate the first horizontal distance D1 between the first vertical side of the electromagnetic beam emitted by the ground base station and the center line of the track, and the second horizontal distance D2 between the second vertical side of the electromagnetic beam and the center of the track;
[0065] According to the vertical distance d1 of the millimeter wave test device relative to the ground base station, the center height h2 of the ground base station antenna and the height h1 of the track surface, the first vertical distance H1 between the first horizontal edge of the electromagnetic beam and the center of the track and the second vertical distance H2 between the second horizontal edge of the electromagnetic beam and the center of the track are calculated.
[0066] Specifically, in practical applications, the first horizontal distance D1 between the first vertical side of the electromagnetic wave beam emitted by the ground base station and the center line of the track can be calculated based on the vertical distance d1 of the millimeter wave test device relative to the ground base station and the horizontal distance d2 between the center of the ground base station and the center line of the track, in combination with the first calculation formula, wherein the first calculation formula is:
[0067] ;in, Indicates the half-power angle of the ground base station in the horizontal direction (such as Figure 5 as shown).
[0068] According to the vertical distance d1 of the millimeter wave test device relative to the ground base station and the horizontal distance d2 between the center of the ground base station and the center line of the track, the second horizontal distance D2 between the second vertical side of the electromagnetic beam and the center of the track is calculated in combination with the second relationship; wherein the second relationship is:
[0069] ;
[0070] According to the vertical distance d1 of the millimeter wave test device relative to the ground base station, the center height h2 of the ground base station antenna and the track surface height h1, the first vertical distance H1 between the first horizontal side of the electromagnetic beam and the track center is calculated in combination with the third relationship; wherein the third relationship is:
[0071] ;in, Indicates the half-power angle in the vertical direction of the ground base station (such as Figure 6 as shown).
[0072] According to the vertical distance d1 of the millimeter wave test device relative to the ground base station, the center height h2 of the ground base station antenna and the track surface height h1, the second vertical distance H2 between the second horizontal side of the electromagnetic beam and the track center is calculated in combination with the fourth relationship; wherein the fourth relationship is:
[0073] .
[0074] It should be noted that in actual use, the high-speed maglev millimeter wave wireless communication system will process the electromagnetic wave beam emitted by the ground base station into a right pyramid with a pitch angle of 5° and a horizontal angle of 20° (or a pitch angle of 5° and a horizontal angle of 30°) to improve the communication distance and anti-interference performance of the system. Therefore, the mathematical model of the electromagnetic wave beam emitted by the ground base station is:
[0075] ; This relationship describes the radio signal coverage model of the high-speed maglev millimeter wave ground base station, where Indicates the radio signal coverage range of the millimeter wave ground base station, in m 3 ; Indicates the half-power angle of the ground base station in the vertical direction; It represents the half-power angle of the ground base station in the horizontal direction; d represents the maximum distance when the radio signal power transmitted by the ground base station is higher than the available standard for reception by the vehicle-mounted base station.
[0076] From the above data model, the mathematical expression of the cross-sectional area of the electromagnetic beam of the ground base station at a fixed vertical distance d1 from the base station can be obtained as follows:
[0077] ;in, Indicates the radio signal coverage range of the millimeter wave ground base station, in m 3 , d1 represents the height of the right pyramid formed by the electromagnetic beam.
[0078] The cross section of the electromagnetic beam transmitted by the ground base station is a rectangle perpendicular to the ground, wherein the two sides perpendicular to the ground are the first vertical side and the second vertical side, and the two sides parallel to the ground are the first horizontal side and the second horizontal side. In practical applications, the horizontal distance d2 between the center of the ground base station and the center line of the track can be obtained by measurement. When the height of the right pyramid formed by the electromagnetic beam at a vertical distance to the ground base station is d1, the horizontal distance between the first vertical side of the cross section of the electromagnetic beam transmitted by the ground base station and the center line of the track is D1, and the horizontal distance between the second vertical side of the cross section of the electromagnetic beam transmitted by the ground base station and the center line of the track is D2, thereby obtaining the first calculation relationship and the second calculation relationship:
[0079] ;
[0080] .
[0081] Considering that the center height of the ground base station antenna is h2 and the height of the track surface is h1, the height of the right pyramid formed by the electromagnetic beam at a vertical distance from the ground base station is When , the vertical distance between the first horizontal side of the electromagnetic beam cross section transmitted by the ground base station and the track surface is H1, and the vertical distance between the second horizontal side of the electromagnetic beam cross section transmitted by the ground base station and the track surface is H2, thereby obtaining the third calculation relationship and the fourth calculation relationship:
[0082] ;
[0083] .
[0084] S130: adjusting the positions of the antennas of the millimeter wave test device according to the distance parameter so that each antenna coincides with each side of the cross section of the electromagnetic beam emitted by the ground base station at a corresponding height;
[0085] In practical applications, the obtained d1, D1, D2, H1 and H2 can be fed back to the millimeter wave test device, and the millimeter wave test device can adjust each antenna according to various parameters.
[0086] In one implementation, the height of the central antenna in the millimeter wave test device in the embodiment of the present invention is the same as the height of the onboard mobile base station of the high-speed maglev train, and the millimeter wave test device is located on the vertical plane where the center line of the track is located;
[0087] Then, the process of adjusting the positions of the antennas of the millimeter wave test device according to the distance parameter in the above S130 so that each antenna coincides with each side of the cross section of the electromagnetic beam emitted by the ground base station at the corresponding height may include:
[0088] According to the first horizontal distance between the first vertical edge of the electromagnetic beam and the center line of the track, the second horizontal distance between the second vertical edge of the electromagnetic beam and the center of the track, the first vertical distance between the first horizontal edge of the electromagnetic beam and the center of the track, and the second vertical distance between the second horizontal edge of the electromagnetic beam and the center of the track, the servo motors corresponding to each peripheral antenna are respectively controlled to adjust the length of the corresponding mechanical arm, so that each peripheral antenna coincides with each side of the cross section of the electromagnetic beam emitted by the ground base station at the corresponding height.
[0089] It should be noted that, after obtaining the various parameters d1, D1, D2, H1 and H2, the millimeter wave testing device in the embodiment of the present invention can control the servo motor to extend or shorten the robotic arm so that the centers of the peripheral antennas around the antenna array coincide with the four sides of the cross-section of the electromagnetic wave beam transmitted by the ground base station, that is, the projections of the peripheral antennas of the adjusted antenna array on the cross-section of the electromagnetic wave beam transmitted by the ground base station coincide with the four sides of the cross-section.
[0090] S140: Determine whether the installation of the ground base station meets preset requirements based on the field strength information collected by each antenna after adjustment.
[0091] Specifically, after each peripheral antenna coincides with each side of the electromagnetic beam cross section at the corresponding height emitted by the ground base station, each antenna in the antenna array receives the electromagnetic wave signal and determines the effective electromagnetic wave signal sent by the ground base station. For each antenna, corresponding field strength information can be obtained based on the effective electromagnetic wave signal received by the antenna, and then a corresponding field strength curve can be obtained based on the field strength information, that is, each antenna corresponds to a field strength curve. In an embodiment of the present invention, it is possible to identify whether the installation of the ground base station meets the preset requirements through the field strength information received by the adjusted antenna array.
[0092] In one implementation, the process of determining whether the installation of the ground base station meets the preset requirements according to the adjusted field strength information respectively collected by each antenna in the above S130 may include:
[0093] A field strength curve corresponding to each antenna is obtained according to the field strength information collected by each antenna;
[0094] When it is determined based on the field strength curves corresponding to each peripheral antenna that the amplitude of the field strength curve of each peripheral antenna is greater than the sensitivity of the vehicle-mounted mobile base station, and the amplitude of the field strength curve of the central antenna is higher than the amplitude of the field strength curve of each peripheral antenna, it is determined that the installation of the ground base station meets the preset requirements.
[0095] It should be noted that after obtaining the corresponding field strength curves of each antenna, the amplitude of the field strength curve of each peripheral antenna can be compared with the sensitivity of the vehicle-mounted mobile base station. When the amplitude of the field strength curve of each peripheral antenna is greater than the sensitivity of the vehicle-mounted mobile base station, if the amplitude of the field strength curve of the central antenna is higher than the amplitude of the field strength curve of each peripheral antenna, it means that the electromagnetic wave beam emitted by the ground base station is consistent with expectations according to the symbol preset requirements.
[0096] In one embodiment, the method may further include:
[0097] The field strength information collected by each antenna is marked separately and sent to the ground display device.
[0098] It should also be noted that the field strength information collected by the five antennas on the millimeter wave test device can be marked and sent to the ground display screen or handheld terminal for display, which is convenient for test personnel to view. The field strength curve corresponding to each antenna can also be displayed on the ground display screen or handheld terminal, so that the staff can intuitively analyze each field strength curve to determine whether the installation of the ground base station meets the preset requirements.
[0099] In practical applications, the millimeter wave test device in the embodiment of the present invention is provided with multiple antennas and positioning modules, and may also include a 5G transceiver unit, a positioning unit, a clock synchronization unit, a main control unit and a power supply unit (such as Figure 7 As shown in the figure), the millimeter wave test device can use the clock synchronization unit to maintain μs-level clock synchronization with the ground base station. Therefore, the millimeter wave test device can generate a local carrier signal with the same frequency and phase as the ground base station and is strictly synchronized. After receiving the signal from the outside world, the millimeter wave test device can determine whether the received signal is a valid electromagnetic wave signal based on whether the received signal is in the same frequency and phase as the local carrier signal, and then extract the effective received signal power from the effective electromagnetic wave signal. As the speed measurement and positioning unit of the millimeter wave test device, the wireless field strength of the location is analyzed, and then the coverage of the line by the ground base station can be judged whether it meets the preset requirements. At the same time, the millimeter wave test device can send the collected field strength information and location information to the ground display screen or the handheld terminal in the hands of the base station installer through the 5G transceiver unit, so that the tester and the installer can check in real time whether the installation of the base station is accurate and qualified. Among them, the speed measurement and positioning unit and the time synchronization unit use the GPS module to obtain GPS positioning data and PPS second pulse data to realize the function.
[0100] It can be seen that in the embodiment of the present invention, the positioning information collected by the positioning module in the millimeter wave testing device can be used, and the distance parameter of the millimeter wave testing device relative to the ground base station can be determined based on the positioning information, and the position of each antenna of the millimeter wave testing device can be further adjusted based on the distance parameter, so that each antenna coincides with each side of the electromagnetic beam cross-section at the corresponding height of the electromagnetic beam emitted by the ground base station. Since the adjusted antennas coincide with each side of the electromagnetic beam cross-section at the corresponding height of the electromagnetic beam emitted by the ground base station, the field strength information collected by the adjusted antennas can be used to determine whether the installation of the ground base station meets the preset requirements, thereby determining whether the electromagnetic beam emitted by the ground base station is consistent with expectations.
