Background
With the rapid development of communication technology, the limited communication resources are crowded, so in order to improve communication efficiency, some communication devices supporting the fifth Generation mobile communication technology (5 th-Generation, 5G) can use radio frequency signals in the millimeter wave band for communication. When the communication device performs 5G millimeter wave communication, a Time Division Duplex (TDD) duplex working mode is adopted, that is, the communication device transmits an uplink millimeter wave signal in a part of slots in a time domain frame and receives a downlink millimeter wave signal in another part of slots.
Radio frequency indexes such as adjacent channel rejection ratio (ACLR) and spectrum template (SEM) of the communication device are used for measuring the communication capability of the communication device, and in order to detect the radio frequency indexes of the communication device, a radio frequency index detection antenna may be controlled by a radio frequency index detector, a beam sphere formed by a radio frequency signal transmitted toward the communication device rotates, an Equivalent Isotropic Radiated Power (EIRP) of each grid point (measurement grid) on the beam sphere is obtained by scanning, and the EIRP is integrated to obtain a Total Radiated Power (TRP) power value of the whole beam sphere to obtain the radio frequency indexes such as ACLR and SEM. Meanwhile, the radio frequency index detector also needs to monitor the radio frequency signal transmitted by the communication equipment through the radio frequency index detection antenna, and when the power of the radio frequency signal is greater than a certain threshold value, it indicates that the communication equipment is transmitting the radio frequency signal at the moment, so that the radio frequency index detector can be triggered to detect the radio frequency index of the communication equipment at the time slot when the communication equipment transmits the signal.
However, since the radio frequency index detection antenna needs to rotate for detection, when the radio frequency index detection antenna rotates to some positions, the power of the radio frequency signal of the communication device received by the radio frequency index detection antenna is low, and the radio frequency index detector cannot be triggered to detect the radio frequency index of the communication device, so that the detection accuracy is low.

Detailed Description
Before formally introducing the embodiments of the present application, first, a description is given, with reference to the accompanying drawings, of a communication device provided in the embodiments of the present application and a problem in an existing technology for detecting a radio frequency index of a communication device, where fig. 1 is a functional schematic diagram of the communication device of the present application, and fig. 1 shows an application scenario in which the communication device performs millimeter wave communication in each embodiment of the present application. As shown in fig. 1, the communication device 110 provided by the present application may communicate with the network device 120, and particularly, both the communication device 110 and the network device 120 support receiving and transmitting of millimeter waves, so that the communication device 110 may communicate with the network device 120 or other communication devices through millimeter waves. When the communication apparatus 110 and the network apparatus 120 perform millimeter wave communication, communication performed by the network apparatus 120 transmitting millimeter waves (1) to the communication apparatus 110 is referred to as Downlink (DL) communication, and communication performed by the communication apparatus 110 transmitting millimeter waves (2) to the network apparatus 120 is referred to as Uplink (UL) communication. For example, in the scenario shown in fig. 1, the communication device 110 may be a handset supporting 5G communication, the network device 120 may be a 5G base station, and the handset and the 5G may communicate based on millimeter waves.
Specifically, millimeter wave refers to electromagnetic waves with a frequency range of 30GHz to 300GHz and a corresponding wavelength of 1mm to 10mm, and communication based on millimeter wave refers to communication performed with millimeter waves as carriers for transmitting information. With the rapid development of communication services, especially personal mobile communication, the low-end frequency of the radio spectrum that can be used by communication devices for communication is becoming saturated, and even if various technologies such as modulation and multiple access are used to expand the capacity of communication systems and improve the utilization rate of the spectrum, the requirements of future communication development cannot be met, so that new spectrum resources must be developed to the high-end of microwave to realize high-speed and broadband wireless communication. At this time, due to its short wavelength and wide frequency band, the millimeter wave can effectively solve many problems faced by high-speed broadband wireless access, thereby entering the field of people, and has a wide application prospect in communication devices supporting the fifth Generation mobile communication technology (5 th-Generation, 5G) and even communication devices updated in the future.
Alternatively, the communication device 110 and the network device 120 shown in fig. 1 may be applied to various communication systems in addition to the 5G communication system, for example: global System for Mobile communications (GSM) System, code Division Multiple Access (CDMA) System, wideband Code Division Multiple Access (WCDMA) System, general Packet Radio Service (GPRS), long Term Evolution (LTE) System, advanced Long Term Evolution (LTE-a) System, universal Mobile Telecommunications System (UMTS), or 5G System.
Optionally, the communication device 110 according to the embodiments of the present application may also be referred to as a User Equipment (UE), and the communication device 110 includes, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a handset (handset), or a portable device (portable Equipment). In the scenario shown in fig. 1, the communication device 110 is taken as a mobile phone for illustrative purposes, but is not limited thereto, for example, the communication device 110 may also be a mobile phone (or called "cellular" phone) or a computer with wireless communication function, and the user equipment may also be a portable, pocket, hand-held, computer-embedded or vehicle-mounted mobile device. In addition, the specific type of the network device 120 shown in fig. 1 is not limited, for example, the network device 120 may be a common base station (e.g., nodeB or eNB), a radio remote module, a micro base station (pico), a relay (relay), a Centralized network element (CU), a Distributed network element (DU), a Transmission Point (TP) or a Transmission Reception Point (TRP), a DU and a TP, or any other wireless access device.
In some applications, a provider of a communication device or other related detection mechanism may desire to obtain a radio frequency indicator based on a signaling definition test in order to measure communication performance of the communication device in millimeter wave communication. However, the communication devices, the testers, and the testing methods related to the millimeter waves are all mature, so that the existing communication devices can only perform detection in a non-signaling manner, for example, a test metric (test metric) based on a Total Radiation Power (TRP) can be used to obtain a radio frequency index for measuring the communication devices. The TRP mechanism is configured to scan a beam spherical surface formed by a millimeter wave radio frequency signal transmitted by the communication device, obtain an Equivalent Isotropic Radiated Power (EIRP) of the radio frequency signal at each grid point (measurement grid) on the spherical surface, integrate the EIRPs of all the grid points to obtain a radiation power (TRP) power value of the whole beam spherical surface, and calculate radio frequency indexes such as an (initial channel leakage ratio, ACLR), a spectrum template (spectrum emission mask, SEM) and the like of the communication device, so that the communication performance of the communication device during millimeter wave communication can be measured by the radio frequency indexes.
For example, fig. 2 is a schematic structural diagram of a radio frequency index detection apparatus in the prior art, where the radio frequency index detection apparatus 1 may be used to perform TRP mechanism detection on a communication device 2 placed in the apparatus, and obtain a radio frequency index of the communication device by scanning a beam spherical surface 21 formed by a radio frequency signal emitted by the communication device 2. As shown in fig. 2, the radio frequency index detection apparatus 1 includes: revolving stage 11, first rotating part 12, radio frequency index detection antenna 13 and radio frequency index detector 14, wherein, first rotating part 12 sets up on revolving stage 11, the one end and the revolving stage 11 fixed connection of first rotating part 12, the other end of first rotating part 12 is used for supporting the communication equipment 2 that the radio frequency index detection device 1 waited to detect, when circular shape revolving stage 11 rotates in a direction in the picture, drive the in-plane rotation that communication equipment 2 the diameter R place of wave beam sphere 21 in the picture through first rotating part 12.
The radio frequency index detection antenna 13 in the radio frequency index detection device 1 is used for scanning millimeter wave radio frequency signals sent by the communication equipment 2 on the beam spherical surface 21, the radio frequency index detection antenna 13 is connected with the radio frequency index detector 14, the radio frequency index detection antenna 13 sends data obtained by scanning to the radio frequency index detector 14, and the radio frequency index detector 14 further obtains radio frequency indexes. The position of the rf index detecting antenna 13 is not fixed, and the rf index detecting antenna 13 can rotate around the communication device 2 in the plane of fig. 2 in the direction of b in the drawing, and when the rf index detecting antenna 13 rotates, the whole range of the rf index detecting antenna faces the beam spherical surface 21 formed by the rf signals transmitted by the communication device 2. The turntable 11 rotates in the direction a and the rf index detection antenna 13 rotates in the direction b, so that the rf index detection antenna 13 can scan the EIRP at each grid point on the whole beam spherical surface 21. Alternatively, the rotating table 11 and the rf index detecting antenna 13 may be rotated regularly under the control of the rf index detector 14.
Meanwhile, for the communication device 2, a Time Division Duplex (TDD) duplex working mode is usually adopted when performing 5G millimeter wave communication, that is, the communication device 2 sends an uplink millimeter wave signal in a part of slots (slots) in a time domain frame, and receives a downlink millimeter wave signal in another part of slots. For example, fig. 3 is a time slot distribution diagram of radio frequency signals of a communication device, and in consecutive time slots (1) to (8) within time t of 5G millimeter wave communication by the communication device 2, in time slots (1), (2), (5), (6), and (7), it is necessary to receive millimeter wave radio frequency signals on the downlink DL, and in time slots (3), (4), and (8), it is necessary to transmit millimeter wave radio frequency signals on the uplink UL.
Therefore, the rf index detecting antenna 13 in the rf index detecting apparatus 1 shown in fig. 2 needs to scan the millimeter wave rf index transmitted by the communication device 2 on the beam spherical surface 21 when the communication device 2 transmits the millimeter wave rf signal. In some techniques, the power of the radio frequency signal transmitted by the communication device 2 may be detected by arranging a power meter and an amplifier at a position where the radio frequency index detection antenna 13 is located as in fig. 2, and after the power meter detects the power of the radio frequency signal transmitted by the communication device 2, the power meter is amplified by the amplifier, and the amplified power value is sent to the radio frequency index detector 14. When the amplified power value is greater than a certain threshold, for example, the threshold may be-30 to 10dBm, which indicates that the communication device 2 is transmitting the millimeter wave radio frequency signal on the uplink UL at this time, and the amplified power value transmitted by the radio frequency indicator detecting antenna 13 to the radio frequency indicator detector 14 at this time may be regarded as a trigger (trigger) signal. After receiving the trigger signal, the rf indicator detector 14 may control the rf indicator detecting antenna 13 to scan the beam spherical surface 21. Finally, after the radio frequency index detector 14 controls the radio frequency index detection antenna 13 according to the trigger signal to complete scanning of the EIPR of each grid point on the whole beam sphere, the radio frequency index detector 14 further integrates the EIRP of all the grid points to obtain the ACLR and SEM radio frequency indexes of the communication device 2.
However, when the communication device 2, such as a mobile phone, performs 5G millimeter wave communication in the frequency band range of 5G millimeter waves, the communication device 2 transmits 5G millimeter wave radio frequency signals in the form of directional electromagnetic wave beams through its radio frequency module (e.g., wires), so that the signal power of the communication device 2 at each grid point on the beam spherical surface 21 is not the same. For example, in fig. 2, it is assumed that the rf module of the communication device 2 is located at the upper right of the communication device 2, and the rf module is closest to a point B on the beam spherical surface 21, so that the power value of the rf signal transmitted by the communication device 2 is the largest at the point B. At this time, when the power meter disposed at the radio frequency index detection antenna 13 detects the transmission power of the communication device 2, the power can be obtained more directly and accurately according to the signal transmitted by the communication device 2. However, once the radio frequency module of the communication device 2 rotates to be closest to the point a on the beam spherical surface 21 when the communication device 2 is rotated by the first rotating part 12, the power value of the radio frequency signal emitted by the communication device 2 is the largest at the point a. At this time, when the power meter detects the transmission power of the communication device 2, the transmission power of the radio frequency signal transmitted by the communication device 2 cannot be directly and accurately detected due to a long distance and the blockage of the communication device 2. Therefore, the power value sent by the power meter to the radio frequency index detector 14 through the amplifier is always small, even if the communication device 2 sends a millimeter wave radio frequency signal through a power module of the communication device, the power value sent to the radio frequency index detector 14 cannot be larger than a threshold value and is used as a trigger signal, and then the radio frequency index detector 14 cannot control and trigger the radio frequency index detection antenna 13 to scan the beam spherical surface 21 according to the trigger signal, so that the detection efficiency and the detection accuracy of the radio frequency index detection device 1 are greatly reduced. In addition, in some setting modes, when the power meter and the amplifier are arranged at the position of the radio frequency index detection antenna 13 to detect the transmission power of the communication device 2, the distance from the communication device 2 is long, so that a higher requirement is put on the dynamic range of the set power meter and amplifier pair, and the complexity of the whole radio frequency index detection device 1 is higher.
The application provides a radio frequency index detection device and a radio frequency index detection method, which aim to solve the technical problem that in the prior art, the detection accuracy is low because a detection index detector cannot be triggered to detect radio frequency indexes of communication equipment in time. The technical means of the present application will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Example one
Fig. 4 is a schematic structural diagram of a first embodiment of the radio frequency index detection apparatus provided in the present application, wherein the radio frequency index detection apparatus 1 shown in fig. 4 can be used for performing detection based on a TRP mechanism on a communication device 2 in the apparatus, and obtaining a radio frequency index of the communication device by scanning a beam spherical surface 21 formed by a radio frequency signal emitted by the communication device 2.
As shown in fig. 4, the radio frequency index detection apparatus 1 provided in this embodiment includes: the device comprises a power detection module 15, a radio frequency index detector 14, a radio frequency index detection antenna 13 and a rotating assembly; the rotating component may be configured to rotate the communication device 2 to be detected placed in the radio frequency indicator detecting apparatus 1, so that the power detection antenna 13 can scan a beam spherical surface 21 formed by a radio frequency signal emitted by the communication device 2.
In the first embodiment, the rotating assembly includes: revolving stage 11, first rotating part 12 sets up on revolving stage 11, the one end and the revolving stage 11 fixed connection of first rotating part 12, and the other end of first rotating part 12 is used for supporting the communication equipment 2 that the radio frequency index detection device 1 waited to detect, and when circular revolving stage 11 rotated in a direction in the picture, the planar rotation at the diameter R place of beam sphere 21 in the picture was driven communication equipment 2 through first rotating part 12.
The power detection module 15 is also disposed on the rotating platform 11, and when the rotating platform 11 rotates in the direction a in the figure, in addition to the communication device 2 being driven to rotate in the direction a by the first rotating part 12, the power detection module 15 and the communication device 2 are also driven to rotate in the direction a synchronously in a first plane, which is a cross section parallel to the circular rotating platform 11 in the beam spherical surface 21 in the figure and has a cross-sectional diameter R shown in the figure. Also, the relative position between the power detection module 15 and the communication device 2 remains unchanged throughout the rotation. For example, in the example shown in fig. 4, the first rotating section 12 may be disposed at the center of the circular rotary table 11, and the power detection module 15 may be disposed at any position between the center of the circular rotary table 11 and the circumference, so that the distance between the power detection module 15 and the communication apparatus 2 supported by the first rotating section 12 at the center of the circle is constant when the rotary table 11 rotates. It should be noted that the positions of the first rotating unit 12 and the power detection module 15 on the rotating platform 11 shown in fig. 4 are only exemplary, and the present application is not limited to other possible arrangement modes on the rotating platform 11 that can keep the positions between the two relatively fixed.
In the first embodiment shown in fig. 4, the power detection module 15 may be a millimeter wave power probe. The power detection module 15 is configured to detect a power level of a radio frequency signal transmitted by the communication device 2, and since a relative position between the power detection module 15 and the communication device 2 is fixed, the power detection module 15 can detect the power level of the radio frequency signal of the communication device 2 on the beam spherical surface 21 relatively directly and accurately no matter the communication device 2 is driven by the rotating component to rotate to any position.
Alternatively, the millimeter wave power probe of the power detection module 15 may be aligned to a point on the beam spherical surface 21 where the power of the radio frequency signal transmitted by the communication device 2 is maximum, for example, in fig. 4, the shown mesh point of the radio frequency signal transmitted by the communication device 2 on the beam spherical surface 21 where the power is maximum is point c, the power detection module 15 may be disposed below point c, and the power detection module 15 is aligned to point c on the beam spherical surface 21. That is, in the present embodiment, the position of the power detection module 15 may be set according to the power maximum point of the radio frequency signal transmitted by the communication device 2. Alternatively, in other possible implementations, the power detection module 15 may not be disposed directly below the point c, but may be disposed at any other position on the rotating platform 11, and in this case, the orientation of the power detection module 15 needs to be adjusted so as to keep the power detection module 15 aligned with the point c.
The power detection module 15 in this embodiment may obtain a millimeter wave radio frequency signal on the beam spherical surface 21, convert the radio frequency signal in the form of an electromagnetic wave into an electrical signal for indicating the power of the electromagnetic wave, and send the electrical signal to the radio frequency index detector 14. The electrical signal sent by the power detection module 15 may be used to indicate, by the size of the power of the electromagnetic wave, whether the communication device 2 is transmitting a millimeter wave radio frequency signal, for example, when the communication device 2 transmits a millimeter wave radio frequency signal, the power of the c point where the power is the largest on the beam spherical surface 21 is-20 dBm, which may use-20 dBm as a preset threshold, and when the power detection module 15 detects that the power of the c point is-30 dBm and is smaller than the preset threshold, which indicates that the communication device 2 does not transmit a millimeter wave radio frequency signal at this time, the power detection module 15 may send the power smaller than the preset threshold to the radio frequency index detector 14 in the form of an electrical signal; when the power detection module 15 detects that the power at the point c is-10 dBM and greater than the preset threshold, which indicates that the communication device 2 is transmitting a millimeter wave radio frequency signal, the power detection module 15 sends the power greater than the preset threshold to the radio frequency index detector 14 in the form of an electrical signal.
Accordingly, for the radio frequency index detector 14, it needs to detect the communication device 2 when the communication device 2 is transmitting a millimeter wave radio frequency signal, and therefore, only when the received electrical signal is used to indicate that the power of the point c detected by the current power detection module 15 is-10 dBM and is greater than the preset threshold, that is, when it is determined that the communication device 2 is transmitting a millimeter wave radio frequency signal, the radio frequency index detection antenna 13 is further controlled to scan the radio frequency signal transmitted by the communication device 2 on the beam spherical surface 21, and the radio frequency index of the communication device 2 is determined according to the scanning result. In the embodiment of the present application, the specific implementation manner of scanning the beam spherical surface 21 by the radio frequency index detection antenna 13 to obtain the EIPR of each grid point, and further integrating the EIRPs of all grid points to obtain the ACLR and SEM radio frequency indexes of the communication device 2 is not limited, and reference may be made to the definitions of these radio frequency indexes in the prior art.
Optionally, the power detection module 15 may send indication information to the radio frequency index detector 14 after detecting that the power of the millimeter wave radio frequency signal transmitted by the communication device 2 is greater than a preset threshold, so as to indicate to the radio frequency index detector 14 that the communication device 2 is transmitting the millimeter wave radio frequency signal; alternatively, as described in the previous paragraph, the power detection module 15 may further send the detected power of the millimeter wave radio frequency signal transmitted by the communication device 2 to the radio frequency index detector 14 in the form of an electrical signal in real time, and the radio frequency index detector 14 further determines whether the power is greater than a preset threshold according to the electrical signal, and after determining that the power is greater than the preset threshold, may further scan the communication device 2, in which case, the electrical signal for indicating that the power is greater than the preset threshold may also be regarded as the indication information. The indication information may also be referred to as a trigger (trigger) signal in some implementations.
More specifically, the radio frequency index detecting antenna 13 and the radio frequency index detector 14 are connected as a detecting device, the radio frequency index detecting antenna faces a beam spherical surface 21 formed by a radio frequency signal transmitted by the communication device 2, and the radio frequency index antenna 13 can also rotate in a third plane as shown in the figure by taking the communication device 2 as a center of a circle according to a direction b in the figure, where the third plane is perpendicular to the first plane. Moreover, in the process that the communication device 2 is driven by the rotating component to rotate, the radio frequency index detection antenna 13 always faces the beam spherical surface 21, and under the condition that the rotating platform 11 rotates in the direction a and the radio frequency index detection antenna 13 rotates in the direction b to cooperate with each other, the radio frequency index detection antenna 13 can scan the EIRP of each grid point on the whole beam spherical surface 21 to obtain the radio frequency signal transmitted by the communication device 2. After receiving the indication information, the radio frequency index detector 14 may control the radio frequency index detection antenna 13 to scan the radio frequency signal transmitted by the communication device 2 on the whole beam spherical surface 21 in the time slot in which the communication device 2 transmits the millimeter wave radio frequency signal according to the indication information, and further determine the radio frequency index of the communication device 2 according to the scanning result after obtaining the scanning result of all grid points on the beam spherical surface 21.
In summary, in the radio frequency index detection apparatus 1 provided in this embodiment, the specially-arranged power detection module 15 is used to detect the power of the millimeter wave signal transmitted by the communication device 2, and particularly, in the process that the communication device 2 rotates during detection, the power detection module 15 can also keep stationary and fixed relative to the communication device 2, so that the power detection module 15 can detect the transmission power of the communication device 2 relatively directly and accurately, and then send instruction information to the radio frequency index detector 14 in time to trigger the radio frequency index detector 14 to detect the communication device 2 when the communication device 2 transmits the millimeter wave signal. Compared with the prior art as shown in fig. 2, the problem that the antenna for transmitting the directional electromagnetic wave beams is far away from the power detection module 15 due to the rotation of the communication device 2, so that the detection power is low and the radio frequency index detector 14 cannot be triggered can be effectively prevented, and the accuracy of whether the communication device 2 transmits the millimeter wave signals or not can be greatly improved. In addition, since the circularly polarized horn antenna 151 provided in this embodiment may be disposed on the same turntable 11 as the communication device 2, and the distance between the two is short, the requirements of the dynamic range of the modules such as the power detection module 15 in the form of a power meter are also reduced, and the complexity of the whole rf index detection apparatus 1 is further reduced.
Example two
Fig. 5 is a schematic structural diagram of a second embodiment of the radio frequency indicator detection apparatus provided in the present application. The radio frequency index detection apparatus 1 shown in fig. 5 can also be used for TRP mechanism-based detection of the communication device 2 in the apparatus, and a beam spherical surface 21 formed by radio frequency signals emitted by the communication device 2 is scanned to obtain a radio frequency index of the communication device.
As shown in fig. 5, the radio frequency index detection apparatus 1 provided in this embodiment includes: power detection module 15, radio frequency index detector 14, radio frequency index detection antenna 13 and rotating assembly. For the description of the communication device 2, the rf indicator detector 14, the rf indicator detecting antenna 13 and the rotating component, reference may be made to the description of the first embodiment shown in fig. 4, and the implementation manner and the principle are the same, and are not described again.
Specifically, the power detection module 15 in the radio frequency index detection apparatus 1 shown in the present embodiment includes: a circular polarization horn antenna 151 and a power meter 152, wherein the circular polarization horn antenna 151 is used for receiving the radio frequency signals transmitted by the communication device 2 and transmitting the received radio frequency signals in the form of electromagnetic waves to the power meter 152. The power meter 152 is configured to convert the received radio frequency signal in the form of electromagnetic wave into indication information in the form of electrical signal, and send the indication information in the form of electrical signal to the radio frequency index detector 14.
Therefore, the radio frequency index detection apparatus 1 provided in this embodiment can effectively prevent the problem that the antenna that emits the directional electromagnetic wave beam is far away from the power detection module 15 due to the rotation of the communication device 2, so that the detected power is low, and the radio frequency index detector 14 cannot be triggered, thereby greatly improving the accuracy of whether the communication device 2 emits the millimeter wave signal. In addition, since the circular polarization horn antenna 151 provided by this embodiment and the communication device 2 can be disposed on the same turntable 11 at a close distance, the power of the radio frequency signal detected by the circular polarization horn antenna 151 and transmitted to the power meter 152 is small, so that the requirements for the dynamic range of the antenna, the amplifier and other modules are reduced, and the complexity of the whole radio frequency index detection apparatus 1 is further reduced.
EXAMPLE III
In the first and second embodiments, the distributed-radio-frequency detection apparatus (distributed-antennas system) is taken as an example to explain the technical solution of the present application, and in other possible implementations, the technical solution of the present application may also be applied to a combined-radio-frequency detection apparatus (combined-antennas system).
For example, fig. 6 is a schematic structural diagram of another radio frequency index detection apparatus in the prior art, wherein the radio frequency index detection apparatus shown in fig. 6 includes: the method comprises the following steps: revolving stage 11, first rotating part 12, second rotating part 17, radio frequency index detect antenna 13 and radio frequency index detector 14, and wherein, first rotating part 12 sets up on revolving stage 11, and the one end and the revolving stage 11 fixed connection of first rotating part 12, the one end of second rotating part 17 is connected to the other end of first rotating part 11, and the other end of second rotating part 17 is used for supporting communication equipment 2. When the circular rotary table 11 rotates in the direction a in the figure, the communication device 2 is driven by the first rotating part 12 to rotate in a first plane parallel to the section of the rotary table 11 in the beam spherical surface 21, the diameter of the first plane is the plane of the second rotating part 17 in the figure, and the first rotating part 11 can be referred to as rotating on the "AZ axis" when rotating; when the second rotating part 17 rotates in the direction c in the figure, the second rotating part 17 can drive the communication device 2 to rotate in a second plane where the diameter R of the beam spherical surface 21 in the figure is located, where the first plane and the second plane are perpendicular, and when the second rotating part 17 rotates, the second rotating part may also be called to rotate on a "Roll axis". The radio frequency index detection antenna 13 is used for scanning millimeter wave radio frequency signals sent by the communication device 2 on the beam spherical surface 21, the radio frequency index detection antenna 13 is connected with the radio frequency index detector 14, the radio frequency index detection antenna 13 sends scanned data to the radio frequency index detector 14, and the radio frequency index detector 14 further obtains radio frequency indexes. For the specific implementation of the rf index detecting antenna 13 connected to the rf index detector 14, reference may be made to the embodiment shown in fig. 2. When the turntable 11 rotates the first rotating portion 12 in the direction a and the second rotating portion 17 in the direction c, the rf index detecting antenna 13 may remain stationary, and the first rotating portion 12 and the second rotating portion 17 may cooperate to enable the rf index detecting antenna 13 to scan the EIRP of each grid point on the whole beam spherical surface 21. Alternatively, when the rotating platform 11 drives the first rotating portion 12 to rotate in the direction a and the second rotating portion 17 to rotate in the direction c, the rf index detecting antenna 13 may also rotate in the direction c, and the first rotating portion 12, the second rotating portion 17 and the rf index detecting antenna 13 may cooperate together to enable the rf index detecting antenna 13 to scan the EIRP of each grid point on the whole beam spherical surface 21.
However, in the combined rf detection apparatus shown in fig. 6, the same technical problem as the distributed rf detection apparatus shown in fig. 2 exists, that is, when the communication device 2 rotates to a certain angle, for example, to L shown by a dotted line in fig. 6, when the communication device 2 detects the transmission power of the communication device 2, due to the obstruction of the communication device 2 itself and the first and second rotating portions 12 and 17, the transmission power of the rf signal transmitted by the communication device 2 cannot be directly and accurately detected, and even at the position L, the rf index detector 14 cannot be triggered in time to control and trigger the rf index detection antenna 13 to scan the beam spherical surface 21, so that the detection efficiency and the detection accuracy of the rf index detection apparatus 1 are greatly reduced.
Therefore, in the third embodiment of the present application, a combined radio frequency detection apparatus is provided to solve the technical problem that, in the prior art as shown in fig. 5, a detection index detector cannot be triggered in time to detect a radio frequency index of a communication device, so that the detection accuracy is low.
Fig. 7 is a schematic structural diagram of a third embodiment of the radio frequency index detection apparatus provided in the present application, wherein the radio frequency index detection apparatus 1 shown in fig. 7 includes: a radio frequency index detection antenna 13, a radio frequency index detector 14 and a power detection module 15; the rotating assembly in this embodiment includes: a rotary table 11, a first rotating unit 12, and a second rotating unit 17; regarding the working modes of the rotating platform 11, the first rotating portion 12, the second rotating portion 17, the rf index detecting antenna 13, the rf index detecting instrument 14, and the power detecting module 15, reference may be made to the description in the foregoing embodiments of the present application, and the implementation mode and principle thereof are the same, and are not repeated herein.
In particular, in the radio frequency index detecting apparatus 1 shown in fig. 7, the power detecting module 15 is also disposed on the rotating platform 11, when the rotating platform 11 rotates in the direction a in the figure, in addition to the communication device 2 being driven to rotate in the direction a by the first rotating portion 12, the power detecting module 15 and the communication device 2 are driven to rotate in the direction a synchronously in the first plane, and the relative position between the power detecting module 15 and the communication device 2 is kept unchanged during the whole rotation process. When the second rotating portion 17 rotates in the direction c in the drawing, the power detection module 15 is not driven to rotate together, but at this time, even after the point c rotates to the upper side in the drawing, compared with the position L shown in fig. 6, because the change of the relative position between the power detection module 15 and the communication device 2 is greatly reduced, the change of the power required by the power detection module 15 has a smaller dynamic range, and the situation that the power cannot be detected because the signal cannot be received at the position L does not occur, the power detection module 15 can detect the power of the rf signal of the communication device 2 on the beam spherical surface 21 more directly and accurately.
In summary, in the radio frequency index detection apparatus 1 provided in this embodiment, the specially-arranged power detection module 15 is used to detect the power of the millimeter wave signal transmitted by the communication device 2, and especially in the process that the communication device 2 rotates during detection, the power detection module 15 can directly and accurately detect the transmission power of the communication device 2, so as to send indication information to the radio frequency index detector 14 in time, so as to trigger the radio frequency index detector 14 to detect the communication device 2 when the communication device 2 transmits the millimeter wave signal. Compared with the prior art as shown in fig. 5, the problem that the antenna emitting the directional electromagnetic wave beam is far away from the power detection module 15 at the position L to cause low detection power and cannot trigger the radio frequency index detector 14 due to the rotation of the communication device 2 can be effectively prevented, and the accuracy of whether the communication device 2 emits the millimeter wave signal or not is greatly improved. In addition, the circularly polarized horn antenna 151 provided by this embodiment may be disposed on the same turntable 11 as the communication device 2, and the distance between the circularly polarized horn antenna 151 and the communication device 2 is short, so that the requirements of the dynamic ranges of the modules such as the power detection module 15 in the form of a power meter are reduced, and the complexity of the whole rf index detection apparatus 1 is further reduced.

In the embodiment shown in fig. 8, the radio frequency index detection apparatus 1 includes: power detection module 15, radio frequency index detector 14, radio frequency index detection antenna 13 and rotating assembly. For the description of the communication device 2, the rf index detector 14, the rf index detecting antenna 13 and the rotating component, reference may be made to the description of the third embodiment shown in fig. 7, and the implementation manner and principle thereof are the same, and are not described again.
Specifically, the power detection module 15 in the radio frequency index detection apparatus 1 shown in the present embodiment includes: a circular polarization horn antenna 151 and a power meter 152, wherein the circular polarization horn antenna 151 is used for receiving the radio frequency signals transmitted by the communication device 2 and transmitting the received radio frequency signals in the form of electromagnetic waves to the power meter 152. The power meter 152 is configured to convert the received radio frequency signal in the form of electromagnetic wave into indication information in the form of electrical signal, and send the indication information in the form of electrical signal to the radio frequency index detector 14.
Therefore, the radio frequency index detection apparatus 1 provided in this embodiment can effectively prevent the problem that the antenna that emits the directional electromagnetic wave beam is far away from the power detection module 15 due to the rotation of the communication device 2, so that the detection power is low, and the radio frequency index detector 14 cannot be triggered, thereby greatly improving the accuracy of whether the communication device 2 emits the millimeter wave signal. In addition, since the circular polarization horn antenna 151 provided by this embodiment and the communication device 2 can be disposed on the same turntable 11 at a close distance, the power of the radio frequency signal detected by the circular polarization horn antenna 151 and transmitted to the power meter 152 is small, so that the requirements for the dynamic range of the antenna, the amplifier and other modules are reduced, and the complexity of the whole radio frequency index detection apparatus 1 is further reduced.
