Therefore, reasonable and efficient installation and testing of millimeter wave base stations are important challenges to realize the engineering application of high-speed maglev system. Due to environmental factors such as stations, high-rise buildings and warehouses along the high-speed maglev track, the field strength distribution on the track usually shows periodic fading. In order to improve the communication distance and anti-interference performance of the system, the existing high-speed maglev millimeter wave wireless communication system usually uses diversity antennas to improve the signal quality received by the vehicle-mounted mobile base station. Since the environmental factors on both sides of the line are difficult to simulate in a laboratory environment, the diversity characteristics of the designed antenna are usually not perfectly adapted to each track area. In severe cases, the field strength coverage effect of some sections cannot meet the minimum requirements of the system, affecting the normal operation of the system. However, it is not possible to detect the adaptability of the diversity characteristics of the antenna, which affects the debugging accuracy of the system.

[0053] The embodiments of the present invention provide a method, device, electronic device and computer-readable storage medium for testing the diversity antenna of a magnetic levitation millimeter wave vehicle-mounted mobile base station. During use, the diversity performance of the antenna of the magnetic levitation millimeter wave vehicle-mounted mobile base station can be detected, which is beneficial to improving the system debugging accuracy.

[0054] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Please refer to Figure 1 , Figure 1 A flow chart of a method for testing a diversity antenna of a magnetic levitation millimeter wave vehicle-mounted mobile base station provided in an embodiment of the present invention. The method comprises:

[0056] S110: Acquire electromagnetic wave signals and position information received by a test device disposed on the rail tractor, and obtain field strength information according to the electromagnetic wave signals; wherein the electromagnetic wave signals are collected by a diversity antenna on the test device during movement of the rail tractor;

[0057] It should be noted that the test device in the embodiment of the present invention can be set on a rail tractor, and the rail tractor is used to replace the actual train operation, thereby shortening the test time and test difficulty. A diversity antenna (that is, a diversity antenna for being set on a magnetic levitation millimeter wave vehicle-mounted mobile base station) can be set on the test device, and can be specifically set on the diversity antenna mounting frame of the test device, and the diversity antenna can be lifted to the same height as the installation position of the diversity antenna of the vehicle-mounted mobile base station of the train through the diversity antenna mounting frame. The rail tractor can move along the track, specifically from one end of a wireless partition to the other end. During the movement of the rail tractor, the diversity antenna on the test device can receive the electromagnetic wave signal sent by the ground base station, and the speed measurement and positioning module on the test device can obtain the corresponding position information. The test device sends the electromagnetic wave signal and position information corresponding to the electromagnetic wave signal to the main control unit, and the main control system obtains the corresponding field strength information according to the electromagnetic wave signal.

[0058] It can be understood that in practical applications, the test device in the embodiment of the present invention may include a diversity antenna mounting bracket, a millimeter wave receiving front end, a positioning unit, a 5G transceiver unit, a clock synchronization unit, and a power supply unit. Of course, the active unit may also be integrated in the test device (such as Figure 2 As shown), it can also be set on other equipment, the diversity antenna is installed on the diversity antenna mounting frame, and the diversity antenna mounting frame is responsible for carrying the millimeter wave planning on the mobile base station RF front end and the reflector antenna. The 5G transceiver unit in the test device in the embodiment of the present invention can send out the RF signal of the electromagnetic wave signal obtained by the RF front end and the position information obtained by the positioning module, and the active unit can obtain the electromagnetic wave signal and position information received by the test device set on the rail tractor by wireless means.

[0059] S120: constructing a relationship curve between field strength and position according to the field strength information and the position information;

[0060] It should be noted that the test device in the embodiment of the present invention may also be provided with a clock synchronization unit, so that the acquired field strength information and position information are synchronized, so that a field strength and position relationship curve can be constructed according to the field strength information at different times and the corresponding position information.

[0061] S130: Analyze the relationship curve between the field strength and the position to determine whether the diversity antenna meets the preset diversity requirement.

[0062] It is understandable that after obtaining the relationship curve between the field strength and the position, the relationship curve between the field strength and the position can be further analyzed to determine whether the diversity antenna of the millimeter wave vehicle-mounted base station meets the preset diversity requirements.

[0063] In one implementation, the process of constructing a field strength-position relationship curve according to the field strength information and the position information in S110 may include:

[0064] Determine first field strength information corresponding to the first channel and second field strength information corresponding to the second channel from the field strength information;

[0065] Constructing a relationship curve between the first field strength and the position according to the first field strength information and the position information;

[0066] A relationship curve between the second field strength and the position is constructed according to the second field strength and the position information.

[0067] It should be noted that, in the embodiment of the present invention, since the diversity antenna has two receiving channels (i.e., two channels), two diversity signals will be formed, that is, there are two field strength information at each orbital position, so the first field strength information corresponding to the first channel and the second field strength information corresponding to the second channel can be determined based on the acquired field strength information, wherein, since the first channel and the second channel are connected to the main control system via different radio frequency lines, the field strength information corresponding to the channel can be determined based on the signals received by different radio frequency lines, so that the first field strength information corresponding to the first channel and the second field strength information corresponding to the second channel can be obtained, and then a first field strength and position relationship curve is constructed based on the first field strength information and the position information, and a second field strength and position relationship curve is constructed based on the second field strength information and the position information.

[0068] In one implementation, the process of analyzing the relationship curve between field strength and position in S130 to determine whether the diversity antenna meets the preset diversity requirement may include:

[0069] Determine each first deep decay point according to the relationship curve between the first field strength and the position;

[0070] Determine each second deep decay point according to the relationship curve between the second field strength and the position;

[0071] When the second field strength at the position corresponding to each first deep decay point in the relationship curve between the second field strength and the position is greater than or equal to the preset field strength, determining that the diversity antenna meets the preset diversity requirement;

[0072] Or, when the first field strength at the position corresponding to each second deep decay point in the first field strength-position relationship curve is greater than or equal to the preset field strength, it is determined that the diversity antenna of the vehicle-mounted mobile base station meets the preset diversity requirement.

[0073] It should be noted that, according to the fluctuation of the first field strength and position relationship curve, each first deep decay point in the first field strength and position curve can be determined. Considering that only points with field strength less than the preset field strength can better reflect the diversity antenna characteristics, in the embodiment of the present invention, each trough point in the relationship curve can be specifically determined according to the first field strength and position relationship curve as each first trough point, and then each first target trough point with a field strength value less than the preset field strength is determined from each first trough point, and each first target trough point is used as each first deep decay point, thereby determining each first deep decay point.

[0074] Then, each second deep decay point is determined according to the fluctuation of the relationship curve between the second field strength and the position. Considering that only the point with a field strength less than the preset field strength can better reflect the diversity antenna characteristics, in the embodiment of the present invention, each trough point in the relationship curve can be determined according to the relationship curve between the second field strength and the position, and each trough point is used as each second trough point, and then each second target trough point with a field strength value less than the preset field strength is determined from each second trough point, and each second target trough point is used as each second deep decay point, thereby determining each second deep decay point.

[0075] Specifically, after obtaining each first deep decay point and each second deep decay point, it can be determined that the diversity antenna meets the preset diversity requirement when the second field strength at the position corresponding to each first deep decay point in the relationship curve between the second field strength and the position is greater than or equal to the preset field strength; or, when the first field strength at the position corresponding to each second deep decay point in the relationship curve between the first field strength and the position is greater than or equal to the preset field strength, it can be determined that the diversity antenna of the vehicle-mounted mobile base station meets the preset diversity requirement. The test result effect diagram is shown in FIG. Figure 3 shown.

[0076] That is, at each deep attenuation point in the first field strength vs. position curve, if the field strength information at the corresponding position in the second field strength vs. position curve is greater than or equal to the preset field strength, it means that the diversity characteristics of the vehicle-mounted mobile base station antenna meet the actual needs, otherwise it does not meet the requirements; similarly, at each deep attenuation point in the second field strength vs. position curve, if the field strength information at the corresponding position in the first field strength vs. position curve is greater than or equal to the antenna's receiving sensitivity, if it is greater than or equal to, then the diversity characteristics of the vehicle-mounted mobile base station antenna meet the actual needs, otherwise it does not meet the requirements. That is, when the preset diversity requirements are met, it means that the two receiving channels of the diversity antenna are complementary and have two channels with different fading characteristics.

[0077] It should also be noted that the preset field strength in the embodiment of the present invention is determined according to the receiving sensitivity of the diversity antenna.

[0078] In one embodiment, the method may further include:

[0079] The first field strength versus position relationship curve and the second field strength versus position relationship curve are sent to a ground terminal for display.

[0080] It should also be noted that in actual applications, after obtaining the first field strength and position relationship curve and the second field strength and position relationship curve, the first field strength and position relationship curve and the second field strength and position relationship curve can be sent to the ground terminal for display, and the field strength information and position information can be sent to the ground terminal at the same time, and the data can be stored through the ground terminal so that ground staff can more intuitively observe the data collected by the diversity antenna and analyze it.

[0081] In one embodiment, the height of the diversity antenna on the test device is consistent with the height of the diversity antenna on the vehicle-mounted base station.

[0082] Specifically, in order to ensure the accuracy of the test, in actual applications, the diversity antenna can be lifted to the same height as the installation position of the diversity antenna of the train's onboard mobile base station through a diversity antenna mounting bracket, so that the installation height of the diversity antenna on the test device is consistent with the diversity antenna of the onboard base station on the actual train, thereby improving the test accuracy.

[0083] It can be seen that in the embodiment of the present invention, the diversity antenna on the test device arranged on the rail tractor can receive the electromagnetic wave signal sent by the ground base station and collect the position information while moving with the rail tractor, and send the received electromagnetic wave signal and position information to the active device. The main control device obtains the corresponding field strength information according to the received electromagnetic wave signal, and constructs a relationship curve between the field strength and the position according to the field strength information and the position information, and analyzes the relationship curve to determine whether the diversity antenna meets the preset diversity requirements; the present invention can detect the diversity performance of the magnetic levitation millimeter wave vehicle-mounted mobile base station antenna, which is beneficial to improving the system debugging accuracy.

[0084] The present invention also provides a corresponding device for the magnetic levitation millimeter wave vehicle-mounted mobile base station diversity antenna test method, which further makes the method more practical.
