Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a schematic diagram of a prior art radiosphere measurement point. Referring to fig. 1, in the microwave darkroom, when the turntable rotates to each measuring point on the radiation sphere corresponding to the measured piece, the turntable is stopped, the measuring instrument is adopted to measure, and after the measurement is finished, the turntable is restarted to continue to rotate to the next measuring point to measure, so that the transmitting power of the measured piece in all directions in the three-dimensional space is tested. In the existing TRP test, the number of measurement points is usually small, the interval between the measurement points is usually about 15 degrees, and the total number of the measurement points is about 200-300. Although the rotating speed of the turntable can reach 40-80 degrees/second at present, because each test point needs to be stopped, the turntable needs to continuously undergo the acceleration and deceleration processes, and therefore, in practical application, the interval between every two test points is generally about 2-5 seconds, and the time for measuring the TRP once is usually several minutes to tens of minutes.
However, with the development of technology, when more measurement points are added to perform measurement to improve measurement accuracy, the current TRP measurement scheme can result in a problem that measurement time is too long and test efficiency is seriously affected. According to the invention, when the turntable is controlled to rotate to the spherical scanning measuring point, the measuring signal is automatically sent to the measuring instrument, and the measuring instrument is controlled to perform power measurement when the measuring signal is received, so that real-time automatic cooperative measurement between the turntable and the measuring instrument is realized based on the measuring signal, the turntable can perform power measurement without stopping when the turntable rotates to the measuring point, the problem of overlong measuring time caused by the fact that the turntable is stopped to be continuously subjected to acceleration and deceleration when the turntable is started is avoided, and the testing efficiency is improved.
Fig. 2 is a flow chart of a power measurement method according to an embodiment of the present invention. Referring to fig. 2, an embodiment of the present invention provides a power measurement method, which is applied to a controller, and the method specifically includes the following steps:
In the embodiment of the invention, the control machine is connected with the turntable in the microwave dark room through one end of the measuring instrument, the turntable is provided with the measured piece which rotates along with the turntable, and the control machine is connected with the measuring antenna in the microwave dark room through the other end of the measuring instrument. In the specific implementation, the control machine can be an upper computer, system test software can be run on the upper computer, and the turntable can be controlled to rotate at a constant speed by adopting the system test software, so that the measuring antenna can perform spherical scanning on a measured piece, and the turntable can rotate at a constant speed in the spherical scanning process. In one example, the control may control the turntable to rotate at a constant speed of 30 degrees/second. It should be noted that the above rotation speed of the turntable at a constant speed is merely an example of the present invention, and those skilled in the art may control the turntable to rotate at a constant speed at other rotation speeds according to actual needs, which is not limited herein.
Specifically, the control machine can directly control the turntable to rotate at a constant speed; the control machine can also control the measuring instrument to enable the measuring instrument to control the turntable to rotate at a constant speed, so that the turntable is indirectly controlled to rotate at a constant speed.
The test piece may be a terminal with a large number of measurement points, and the test piece may be a 5G millimeter wave terminal, for example. Because the 5G millimeter wave terminal adopts a solution of a package Antenna (AiP), the system architecture of deep fusion of the multi-channel radio frequency module and the antenna array means that there is no test port for a connectable instrument between the antenna and the radio frequency link, so that the system cannot be applied to conventional conduction test, i.e. cannot test by directly connecting a tested piece with a test instrument through a radio frequency line. Therefore, in the 5G millimeter wave terminal test, an OTA test is generally used, that is, a tested piece is placed in a microwave darkroom, and the tested piece and the test equipment transmit and receive signals and measure signals through an antenna.
Before the advent of 5G millimeter wave technology, the test standard defined fewer TRP measurement points, since the terminal antennas were typically designed as omni-directional antennas. The 5G millimeter wave terminal supports the beamforming technology, so the number of measurement points needs to be multiplied, taking the test standard given by the wireless communication standard organization 3GPP (3 rd Generation Partnership Project) as an example, 1106 point measurement needs to be performed, in order to improve the test precision in research and development tests, 2 degrees of stepping needs to be performed, and the total spherical scanning of 16200 points is required, if the traditional OTA measurement method is adopted, the one-time test time can reach several hours, and the test efficiency of the 5G millimeter wave terminal is affected.
According to the invention, the turntable is controlled to rotate at a constant speed, so that the turntable does not stop to perform power measurement when rotating to each spherical scanning measurement point, and the problem of overlong measurement time caused by the fact that the turntable is required to continuously undergo acceleration and deceleration processes when the measurement points are more can be avoided, thereby improving the test efficiency.
And 202, controlling the turntable to send a measurement signal to a measuring instrument when the turntable rotates to a spherical scanning measurement point.
Specifically, the turntable can be controlled to send measurement signals to the measuring instrument every time the turntable rotates to a spherical scanning measurement point. In the embodiment of the invention, the turntable is controlled to automatically send the measurement signal to the measuring instrument when rotating to the spherical scanning measurement point in the uniform rotation process, so that the turntable can be measured without stopping.
And 203, controlling the measuring instrument to perform power measurement when the measuring signal is received.
Specifically, each time the turntable rotates to a measurement point, the measuring instrument can receive a measurement signal sent by the turntable. For example, in a spherical scanning process, if there are n measuring points, the measuring instrument can receive n measuring signals sent by the turntable, and can be controlled to perform power measurement each time the measuring instrument receives the measuring signals.
And 204, reading power measurement data from the measuring instrument, and determining a radiation performance parameter measurement result of the measured piece.
Specifically, after one spherical scan is completed, all power measurement data, that is, the power measurement data corresponding to each measurement point, can be read at one time from the test instrument, and weighting operation is performed to obtain a radiation performance parameter measurement result, that is, a TRP measurement result, of the measured piece.
According to the embodiment of the invention, when the turntable is controlled to rotate to the spherical scanning measuring point, the measuring signal is automatically sent to the measuring instrument, and the measuring instrument is controlled to perform power measurement when the measuring signal is received, so that real-time automatic cooperative measurement between the turntable and the measuring instrument is realized based on the measuring signal, the turntable can perform power measurement without stopping when the turntable rotates to the measuring point, the problem of overlong measuring time caused by the fact that the turntable is stopped to be continuously subjected to acceleration and deceleration when the turntable is started is avoided, and the testing efficiency is improved.
In an alternative embodiment, before the control turntable rotates at a constant speed, the method may further include: acquiring a preset spherical scanning step; and configuring the turntable scanning step of the turntable according to the preset spherical scanning step, so that the turntable rotates to a measuring point according to the turntable scanning step.
In a specific implementation, a user can set a spherical scanning step on system test software, the system test software can take the spherical scanning step set by the user as a preset spherical scanning step, and configure the scanning step of the turntable in the microwave dark room according to the spherical scanning step set by the user, so that the turntable rotates to a measuring point according to the configured scanning step.
In one example, a spherical scan step may be set to 5 degrees and a turret scan step may be configured to 5 degrees, thus requiring a total of 2592 points to be measured in one TRP test. In the conventional test scheme, the measurement time required by each measurement point is about 3 seconds, so that one test requires 129 minutes, and the test time is too long; according to the invention, the real-time automatic cooperative measurement between the turntable and the measuring instrument is realized based on the measurement signal, so that the turntable does not need to stop to perform power measurement when rotating to a measuring point, and the turntable is supposed to rotate at a constant speed of 30 degrees/second, and the test time is about 9 minutes only for one test and is far less than the test time required by adopting a traditional test scheme, so that the test efficiency is improved.
In an alternative embodiment, after configuring the turntable scan step of the turntable according to the preset spherical scan step, the method may further include: and setting the turntable into a triggering mode, so that when the turntable rotates to a measuring point according to the scanning stepping of the turntable, a measuring signal is triggered and sent to the measuring instrument.
In the specific implementation, after the system test software configures the scanning stepping of the microwave darkroom turntable, the turntable can be set to a trigger mode at the same time, so that after the turntable reaches a measuring point, a measuring signal can be automatically triggered and the triggered measuring signal can be sent to a measuring instrument, and the turntable can be measured without stopping when the turntable reaches the measuring point.
In an alternative embodiment, the measuring instrument is connected to the turntable by a trigger line, so that the turntable transmits the measuring signal to the measuring instrument by the trigger line.
Specifically, a trigger line can be arranged between the measuring instrument and the turntable for connection, so that after the turntable reaches a measuring point to trigger a measuring signal, the measuring signal can be sent to the measuring instrument through the trigger line to trigger the measuring instrument to measure. In the embodiment of the invention, because the turntable does not need to stop when rotating to a measuring point, the time interval between the turntable and the two measuring points is very short, taking the rotating speed of the turntable as 30 degrees/second and the scanning stepping as 5 degrees as an example, the time interval between the two measuring points is about 167ms, and the measuring instrument needs to receive the measuring signal as soon as possible for measuring.
In an alternative embodiment, after configuring the turntable scan step of the turntable according to the preset spherical scan step, the method may further include: calculating total measurement points according to the preset spherical scanning steps; configuring the total measurement points into the measuring instrument; and setting a triggering mode of the measuring instrument to an external signal triggering mode so that the measuring instrument triggers power measurement when receiving the measuring signal and saves power measurement data.
Specifically, the total measurement point number= (360 degrees/preset spherical scan step) may be adopted 2 And/2, calculating the total measurement points. For example, when the preset spherical scanning step is 2 degrees, the total measurement point number can be calculated to be 16200; when the preset spherical scanning step is 5 degrees, the total measurement point number can be calculated to be 2592.
In a specific implementation, the system test software can calculate the total measurement point number according to a preset spherical scanning step, configure the total measurement point number into the measuring instrument, and set a measurement triggering mode of the measuring instrument to an external signal triggering mode, so that the measuring instrument triggers power measurement and automatically saves power measurement data after receiving a measurement signal triggered by the turntable.
In the embodiment of the invention, when the power measurement times of the measuring instrument reach the total measurement points, the measurement of all the measurement points is finished, and the turntable can be controlled to stop rotating at the moment, so that the test is finished.
In an alternative embodiment, the measuring instrument includes a programmable device FPGA, and the controlling the measuring instrument to perform power measurement when the measuring signal is received includes: and controlling the measuring instrument to adopt the FPGA to measure power when receiving the measuring signal.
In conventional testing methods, the turret is stopped when it is turned to the measuring point, typically with a power measurement on the central processor (Central Processing Unit, CPU) of the meter, and restarted after the measurement is completed.
In the embodiment of the invention, the turntable does not stop giving enough time for the instrument and the test software to measure and read data, and the time interval between the turntable and two measuring points is very short, so that the instrument is required to be capable of quickly measuring power and recording data. Taking the rotation speed of the turntable as 30 degrees/second and the scanning stepping as 5 degrees as an example, the time interval between two measuring points is about 167ms, the measuring instrument needs to finish capturing, measuring and outputting or storing the test data in the time, and the processing time of each time can hardly have any fluctuation, otherwise, the measuring of the next point is influenced, so that the measuring instrument needs to receive the measuring signal and then carry out quick measurement, and the measuring time of the measuring instrument is shortened. In the embodiment of the invention, when the measuring instrument is controlled to receive the measuring signal sent by the turntable, the FPGA is adopted to carry out power measurement, and because the processing time delay of the FPGA is taken as a unit of a sampling clock 983.04MHz of the system, the once sampling measuring time can be ensured to be completed within 1ms, thereby meeting the real-time requirement of the system scheme, realizing near-real-time cooperative measurement between the turntable and the measuring instrument and shortening the measuring time of the measuring instrument.
According to the embodiment of the invention, when the turntable is controlled to rotate to the spherical scanning measuring point, the measuring signal is automatically sent to the measuring instrument, and the measuring instrument is controlled to perform power measurement when the measuring signal is received, so that real-time automatic cooperative measurement between the turntable and the measuring instrument is realized based on the measuring signal, the turntable can perform power measurement without stopping when the turntable rotates to the measuring point, the problem of overlong measuring time caused by the fact that the turntable is stopped to be continuously subjected to acceleration and deceleration when the turntable is started is avoided, and the testing efficiency is improved.
