Detailed Description

To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element and be integral therewith, or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Mobile communication technology has penetrated all around into people's lives, and the demand of base stations is increasing; however, the conventional base station test system only tests a single base station to be tested, and after the test of one base station to be tested is completed, the next base station to be tested needs to be interrupted and manually replaced, so that the next test can be performed. Under the condition that the number of the base stations to be tested is large, the testing efficiency of the base stations is low, a testing engineer needs to work repeatedly, and the testing cost is high. Moreover, due to the particularity of base station products, preheating and presetting values are required to be carried out every time a new product is replaced for testing, and normal testing can be carried out only when stable testing conditions are achieved, so that the time utilization rate is not high; for example, in a high-temperature environment and a low-temperature environment, frequent replacement of the base station may cause changes in environmental conditions, affect the test environment, and cause a waiting time to be required for stabilization, thereby consuming a certain waiting time.

However, in the scheme of continuously testing a plurality of base stations to be tested, there are problems that the test signals received by the base stations to be tested do not correspond, the communication signals of the base stations to be tested conflict with each other, and the cost of the test equipment is high (for example, a corresponding test equipment needs to be configured for each base station to be tested). Therefore, the embodiment of the application provides an automatic test system for the base station, which can continuously and automatically test a plurality of base stations, can improve the test timeliness and reduce the test cost.

In one embodiment, as shown in fig. 1, fig. 1 is a first schematic structural diagram of a base station automation test system in an embodiment, and the base station automation test system 100 includes: a multi-port extension unit 110 for connecting to each base station 200 to be tested, respectively, a spectrometer 120 for connecting to the multi-port extension unit 110, a signal source 130 for connecting to the multi-port extension unit 110, and a computer device 140 for connecting to the spectrometer 120, the signal source 130 and each base station 200 to be tested, respectively.

The computer device 140 is configured to run a base station test script, send a running instruction to any base station 200 to be tested, send a test instruction to the signal source 130, and send a demodulation instruction to the spectrum analyzer 120; the signal source 130 sends a test signal to the base station 200 to be tested through the multi-port extension unit 110 based on the test instruction; the base station 200 to be tested sends a first result obtained by processing the test signal to the computer device 140; the multi-port extension unit 110 transmits the acquired communication signal to the spectrum analyzer 120; the communication signal is generated by the base station 200 to be tested based on the operation instruction; the spectrometer 120 processes the communication signal based on the demodulation instruction, obtains a second result, and sends the second result to the computer device 140.

Specifically, the computer device 140 is respectively connected to the spectrometer 120, the signal source 130 and each base station 200 to be tested; the spectrum analyzer 120 and the signal source 130 are connected to the multi-port extension unit 110 and are respectively connected to each base station 200 to be tested. The computer device 140 runs the base station test script and transmits signals to other devices based on the base station test script; specifically, the computer device 140 sends an operation instruction to any base station 200 to be tested, so that the base station to be tested enters an operation state, and generates and transmits and receives signals. Simultaneously with sending the operating instructions, the computer device 140 also sends test instructions to the signal source 130 and demodulation instructions to the spectrometer.

The test instruction may be used to instruct the signal source 130 to send a test signal to the base station 200 to be tested through the multi-port extension unit; the base station to be tested 200 processes the test signal to obtain a first result and transmits the first result to the computer device 140.

The operation instruction may be used to instruct the base station 200 to be tested to generate a communication signal and transmit the communication signal to the multi-port extension unit 110; the multi-port extension unit 110 forwards the communication signal to the spectrometer 120; the spectrometer 120 processes the communication signal based on the demodulation instruction to obtain a second result, and sends the second result to the computer device 140.

It should be noted that the number of the base stations to be tested is at least two. The computer equipment sends an operation instruction to any base station equipment to be tested, only the base station to be tested which receives the operation instruction enters an operation state, can process and analyze the test signal generated by the received signal source, and can send the result obtained by the processing and analysis to the computer equipment; meanwhile, the base station to be tested can also generate a communication signal and transmit the communication signal to the frequency spectrograph through the multi-port extension unit. Based on the method, the multiple base stations can be tested one by one, and the situation that the multiple base stations to be tested simultaneously analyze the received test signals and influence the analysis result fed back to the computer equipment by the base stations to be tested is avoided; moreover, the influence on the processing of the frequency spectrograph and the accuracy of the test result caused by the fact that the frequency spectrograph receives communication signals generated by a plurality of base stations to be tested at the same time is avoided.

It should be noted that after the base station to be tested completes the test, it is determined that the base station to be tested is the tested base station, the computer device does not send an operation instruction to the tested base station any more, and the tested base station does not process and analyze the test signal and generate the communication signal.

The base station to be tested may be a single antenna base station, a dual antenna base station, or a multi antenna base station, and meanwhile, the standard of the base station to be tested may be an LTE standard, a TD-SCDMA standard, a WCDMA standard, a CDMA standard, or a CDMA2000 standard, etc., which is not limited herein.

The multi-port expansion unit can be used for dividing one path of input signals into two or more paths of equal or unequal signal outputs and/or synthesizing the multiple paths of input signals into one path of output devices. Specifically, the multi-port extension unit may be mainly composed of a combiner and/or a power divider. The multi-port extension unit is used for signal transmission between the signal source and the base station to be tested and also used for signal transmission between the base station to be tested and the frequency spectrograph. Specifically, the signal source can send a test signal to each base station to be tested through the multi-port extension unit; the communication signal generated by the base station to be tested can be transmitted to the frequency spectrograph through the multi-port extension unit.

In particular, the multi-port expansion unit may include a plurality of split ports; the multi-port expansion unit comprises a multi-port expansion unit, a frequency spectrograph and a multi-port expansion unit, wherein a first shunt port of the multi-port expansion unit is used for connecting a signal source, a second shunt port of the multi-port expansion unit is used for connecting the frequency spectrograph, and a third shunt port of the multi-port expansion unit is used for connecting a base station to be tested. The test signal generated by the signal source can be transmitted to the base station to be tested through the first branch port and the third branch port in sequence; and the communication signal generated by the base station to be tested can be transmitted to the frequency spectrograph through the third shunt port and the second shunt port in sequence.

The structure of the multi-port expansion unit can be designed according to the frequency spectrograph, the signal source and the number of the base stations to be tested. It should be noted that the split ports of the multi-port expansion unit may enable bidirectional transmission of signals; the uplink and downlink radio frequency indexes can be simultaneously satisfied in the multiport extension unit.

The frequency spectrograph can be used for testing the performance of the transmitter of the base station to be tested, and can realize power measurement, occupied bandwidth measurement, spectrum measurement, total power dynamic range measurement, frequency error measurement, vector magnitude error measurement, time delay measurement and the like, without limitation. And the frequency spectrograph demodulates and analyzes the communication signal generated by the base station to be tested according to the demodulation instruction to generate a test result, and transmits the test result to the computer equipment, and the computer equipment further processes the test result. It should be noted that the demodulation instruction may correspond to the operation instruction, and different demodulation instructions and operation instructions may be set for different base stations to be tested, so that the base stations to be tested generate communication signals of corresponding frequency bands or frequency points. The communication signal received by the frequency spectrograph is a signal generated by a base station to be tested entering into a running state, and only one base station to be tested can generate and transmit the communication signal in the same test period.

The signal source may be used for a receiver performance test of a base station to be tested, and may implement sensitivity measurement, blocking characteristic measurement, intermodulation measurement, and the like by generating a specific useful signal, an interference signal, or an intermodulation signal, which is not limited herein. The signal source can send a test signal to the base station to be tested according to the test instruction of the computer equipment. It should be noted that the signal source may send a test signal to all base stations to be tested connected to the multiport extension unit, but only the base station to be tested that has received the operation instruction may receive the test signal, generate and transmit the first result to the computer device; or the test instruction sent by the computer equipment corresponds to the base station to be tested which receives the operation instruction, based on the test instruction, the signal source can send out a corresponding test signal, and only the base station to be tested which corresponds to the signal source can receive the test signal and carry out demodulation analysis.

The computer device may be used to run an automated test platform, execute various test scripts, control and operate the spectrometer and signal generator, and select the base station to be tested. Meanwhile, the computer equipment can also realize the functions of automatically correcting line loss, storing test data, displaying test logs, prompting test states and the like. Specifically, the computer device may send an operation instruction to any one of the base stations to be tested, and may also send the operation instruction to the corresponding base stations to be tested one by one according to a preset test period and sequence according to the base station test script. Based on the base station test script, the computer equipment sends an operation instruction to the next base station to be tested after completing the test of one base station to be tested, so that the mutual interference among the base stations to be tested is avoided, and the continuous operation of the automatic test is ensured. In particular, the computer device may be, but is not limited to, various personal computers, notebook computers, and tablet computers.

Further, when all base stations to be tested are base stations of the same type, the computer equipment can send the same operation instruction for different base stations to be tested; correspondingly, the computer device may send the same test instructions to cause the signal sources to send the same test signals. When there are at least two types of base stations in the base stations to be tested, the computer device can generate and send corresponding operation instructions, test instructions and demodulation instructions for the different types of base stations to be tested, so that the corresponding base stations to be tested enter an operation state, and the signal source sends corresponding test signals and the frequency spectrograph demodulates correspondingly. It should be noted that different types of base stations to be tested can correspond to different test flows, and the computer device can send corresponding test instructions to the signal source based on the base station test script, so that the signal source generates a corresponding test flow; and a corresponding demodulation instruction can be sent to the frequency spectrograph, so that the frequency spectrograph demodulates the corresponding frequency band or frequency point. Specifically, the base station test script may be generated according to at least one parameter of the number, type, and sequence of the base stations to be tested. The signal source and the spectrometer can independently complete respective test items and can also complete the test items in a matching way; specifically, the signal source may test receiver indexes of the base station to be tested, such as reference sensitivity; the spectrometer may test transmitter indicators of the base station to be tested, such as maximum output power, error vector magnitude, etc.

Based on the system structure, the embodiment of the application can realize the automatic test of a plurality of base stations, effectively improve the test efficiency, reduce the test cost and reduce the repeated work of test engineers. In addition, according to the number, types and sequencing of the base stations to be tested in actual test, the embodiment of the application can adopt the corresponding multi-port extension units and the base station test scripts, can be flexibly configured, and improves the flexibility of automatic test. Moreover, the embodiment of the application can realize continuous and automatic testing of a plurality of base stations, even different types of base stations, by only configuring one signal source and one frequency spectrograph, thereby greatly reducing the testing cost and effectively improving the testing efficiency.

Compared with a traditional radio frequency test mode, the embodiment of the application connects a plurality of base stations to be tested together and powers on the base stations simultaneously, can fully preheat equipment, achieves a stable state, reduces waiting time, can avoid frequent influence on test environment in the process of replacing the base stations, and can realize long-time unattended operation. Compared with other base station radio frequency test systems in batches, the embodiment of the application is flexible and convenient to build, does not need to be additionally designed, processed and manufactured, only uses a common power divider, an isolator and the like to carry out matching combination, reduces the use of complex passive devices, can also prevent signal interference, and improves the accuracy of the radio frequency performance test of the small base station.

In a specific example, when it is confirmed that each base station to be tested establishes communication connection with the computer device and the multi-port expansion unit, the computer device sends a first operation instruction to the first base station to be tested based on the base station test script, so that the first base station to be tested enters an operation state, and generates and receives signals. The computer equipment also sends a corresponding first test instruction to the signal source so that the signal source sends a first test signal to the first base station to be tested through the multi-port extension unit. The first base station to be tested processes and analyzes the first test signal to obtain a test result (belonging to the first result) of the first receiver, and sends the test result to the computer equipment.

The first base station to be tested generates a first communication signal based on the first operation instruction, and sends the first communication signal to the frequency spectrograph through the multi-port expansion unit. The frequency spectrograph demodulates the first communication signal to obtain a test result (belonging to a second result) of the first transmitter, and sends the test result to the computer device. After the computer equipment obtains the test results of the first receiver and the first transmitter, the first base station to be tested can be confirmed as the tested base station, and the test of the first base station to be tested is completed.

When the test of the first base station to be tested is finished, the computer equipment sends a second operation instruction to the second base station to be tested based on the base station test script so that the second base station to be tested enters an operation state to realize the generation, receiving and sending of signals. And the computer equipment also sends a corresponding second test instruction to the signal source so that the signal source sends a second test signal to a second base station to be tested through the multi-port extension unit. And the second base station to be tested processes and analyzes the second test signal to obtain a test result (belonging to the first result) of the second receiver, and sends the test result to the computer equipment.

And the second base station to be tested generates a second communication signal through the operation instruction, and sends the second communication signal to the frequency spectrograph through the multi-port extension unit. And the frequency spectrograph processes the second communication signal to obtain a test result of the second transmitter, and sends the test result to the computer equipment. After the computer equipment obtains the test results of the second receiver and the second transmitter, the second base station to be tested can be confirmed as the tested base station, the test of the second base station to be tested is completed, and the test of all the base stations to be tested is continuously and automatically completed by recursion in sequence.

In one embodiment, the signal sources may include a first signal source for generating a desired signal, a second signal source for generating an interference signal, and a third signal source for generating an intermodulation signal. The first signal source can send useful signals to the base station to be tested through the multi-port extension unit; the second signal source can send interference signals to the base station to be tested through the multi-port extension unit; the third signal source can send intermodulation signals to the base station to be tested through the multi-port extension unit.

In one embodiment, the computer device may send a reset signal to the corresponding base station to be tested when receiving the test result; the reset signal is used for instructing the base station to be tested to stop running so as to enter the test of the next base station to be tested.

In one embodiment, as shown in fig. 2, fig. 2 is a second schematic block diagram of a base station automation test system in one embodiment, and the multi-port expansion unit includes a first combiner and a second combiner.

The branch port of the first combiner is respectively connected with the frequency spectrograph and the signal source, and the combining port is connected with the combining port of the second combiner. And the shunt port of the second combiner is used for connecting the corresponding base station to be tested.

Specifically, the frequency spectrograph and the signal source are connected with a shunt port of the first combiner; each base station to be tested is correspondingly connected with the shunt port of the second combiner; the combining port of the first combiner is connected with the combining port of the second combiner.

It should be noted that, bidirectional transmission of signals can be realized between the branch port and the combining port of the combiner, that is, the combiner has both the branch characteristic and the combining characteristic. The signal transmission relation can be cut off among all the branch ports of the combiner; the uplink and downlink radio frequency indexes can be simultaneously performed in the combiner.

The branch port of the first combiner is used for connecting a test instrument, wherein the test instrument comprises a frequency spectrograph and a signal source.

And the shunt port of the second combiner is used for connecting the radio frequency port of the base station to be tested. The signal source may transmit the test signal to the base station to be tested sequentially through the branch port of the first combiner, the combining port of the second combiner, and the branch port of the second combiner.

The base station to be tested can send communication signals to the frequency spectrograph through the shunt port of the second combiner, the combining port of the first combiner and the shunt port of the first combiner in sequence.

According to the number of the base stations to be tested, the number of the branch ports of the second combiner can be adjusted, so that each branch port of the second combiner is correspondingly connected with one base station to be tested.

It should be noted that a power divider may be used instead of the combiner; the power divider has a branching characteristic and a combining characteristic, and the branching port and the combining port of the power divider can realize bidirectional transmission of signals, namely, the power divider has the branching characteristic and the combining characteristic. The relation of signal transmission can be cut off among all branch ports of the power divider; the uplink and downlink radio frequency indexes can be simultaneously performed in the power divider.

In one embodiment, as shown in fig. 2, the first combiner is a two-in-one combiner; the second combiner is two unification combiners, trinity combiner, four unification combiners or eight unification combiners.

The first shunt port of the first combiner is connected with the frequency spectrograph, and the second shunt port of the first combiner is connected with the signal source.

Specifically, the branch ports of the two-in-one first combiner are respectively connected with the frequency spectrograph and the signal source; the two-in-one second combiner can be connected with two base stations to be tested, the three-in-one second combiner can be connected with three base stations to be tested, and the eight-in-one second combiner can be connected with eight base stations to be tested. According to actual test requirements, different types of second combiners can be configured, and different test plans can be adapted. For example, when 8 base stations to be tested are automatically tested, the second combiner may be an eight-in-one combiner connected to the corresponding base station to be tested through eight branch ports.

In one embodiment, the first combiner is a four-in-one combiner; the first shunt port of the first combiner is connected with the frequency spectrograph, the second shunt port is connected with the first signal source, the third shunt port is connected with the second signal source, and the fourth shunt port is connected with the third signal source.

In one embodiment, as shown in fig. 3, fig. 3 is a third schematic block diagram of a base station automation test system in one embodiment, and the multi-port extension unit further includes a third combiner; the number of the second combiners is at least two;

the combining port of the third combiner is connected with the combining port of the first combiner, and the shunting port is connected with the corresponding combining port of the second combiner.

Specifically, the multi-port extension unit further includes a third combiner connected between the first combiner and the second combiner. The combining port of the third combiner is connected with the combining port of the first combiner, and the combining ports of the second combiners are correspondingly connected with the shunting ports of the third combiner.

It should be noted that the third combiner may be used to expand the splitting port of the combiner, so as to implement the function of further expanding the connection port of the multi-port expansion unit. When the number of the base stations to be tested is further increased, the multi-port expansion unit can be expanded, and the third combiner is used for switching expansion between the first combiner and the second combiner; the number of the branch ports of the third combiner, the number of the second combiners and the number of the branch ports of the second combiners can be configured according to actual test requirements. Specifically, the third combiner may be a two-in-one combiner, a three-in-one combiner, a four-in-one combiner, or an eight-in-one combiner.

For example, when 16 base stations to be tested are tested, the third combiner may adopt a two-in-one combiner, and the second combiner may adopt an eight-in-one combiner; the two branch ports of the two-in-one combiner are respectively connected with an eight-in-one combiner, and the branch ports of the two eight-in-one combiners can realize the communication connection of 16 base stations to be tested. Or the second combiner and the third combiner both adopt four-in-one combiners; the four branch ports of one fourth-in-one third combiner are respectively connected with one fourth-in-one second combiner; the four-in-one second combiners can realize the communication connection of 16 base stations to be tested.

In one embodiment, the base station automation test system may further include an isolator, a first attenuator, and at least two second attenuators. The branch port of the first combiner is connected with a signal source through an isolator and is connected with a frequency spectrograph through a first attenuator. And the branch port of the second combiner is connected with the corresponding base station to be tested through the second attenuator.

It should be noted that, the isolator is connected to the output port of the signal source, and can be used to prevent the reflected signal from entering the signal source.

The first attenuator can be connected with a radio frequency port of a base station to be tested through a radio frequency cable, and can be used for reducing the transmitting signal power of the base station and preventing a large signal from entering the multi-port extension unit to generate interference.
