[0001] The present invention relates to the field of equipment testing, and in particular to a production testing method, device and system for reducing the number of tests. Background Art

[0002] After production, communication equipment needs to go through a series of factory tests, among which the wireless connection function test of communication equipment is a very critical test item. The wireless connection function test of communication equipment generally involves the test equipment communicating with the device under test and performing data communication, and judging whether the wireless connection function of the device under test is qualified based on the results of data communication.

[0003] Currently, a common method for testing the wireless connection function of a communication device is to divide the frequency band supported by the communication device into several sub-frequency bands and perform multiple tests on each sub-frequency band.

[0004] Using this method to test all communication equipment is very inefficient and requires high testing costs. If this method is used to conduct random inspections of communication equipment, only product problems caused by production system failures or defects in the production process can be determined. The qualified quality of the wireless connection function test of the communication equipment itself cannot be guaranteed. Therefore, there is a problem that efficiency and quality cannot be taken into account during the testing process of communication equipment. Summary of the invention

[0009] Target frequency band update process: determine whether the cumulative number of new devices detected has reached a first preset number. If so, update the target frequency band according to the communication detection results of the target frequency band and the sampling frequency band of each new device.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] It is understood that the terms "first", "second", etc. used in the present invention may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script without departing from the scope of the present invention.

[0026] like Figure 1 , Figure 2 As shown, in one embodiment, a production test method for reducing the number of tests is proposed, which may specifically include the following steps:

[0027] Target frequency band determination process: perform communication detection on the frequency band supported by the device and determine several sub-frequency bands; calculate the value of each communication indicator of each sub-frequency band of each device according to the communication detection result of each device; determine the target frequency band and non-target frequency band according to the value of each communication indicator of each sub-frequency band of each device;

[0028] Target frequency band detection process: After determining the target frequency band, perform communication detection on all target frequency bands of the new device; select a non-target frequency band interval that is not completely the same as the non-target frequency band interval of the previous new device from the non-target frequency band of the new device and record it as the sampling frequency band; perform communication detection on the sampling frequency band of the new device;

[0029] Target frequency band update process: determine whether the cumulative number of new devices detected has reached a first preset number. If so, update the target frequency band according to the communication detection results of the target frequency band and the sampling frequency band of each new device. If not, perform the target frequency band detection process on the next new device and determine whether the cumulative number of new devices detected has reached the first preset number.

[0030] Detection process stop process: Repeat the target frequency band detection process and the target frequency band update process until the setting parameters of the device are changed or the detection process is completed.

[0031] In this embodiment, the device refers to a device that needs to be tested for communication. In the actual testing process, the devices can be considered to be tested one by one in sequence, similar to an assembly line.

[0032] In this embodiment, if the setting parameters of the device have not changed, the entire detection process is regarded as a detection cycle until there is no device to be detected, that is, the detection process is completed. The target frequency band determination process, the target frequency band detection process, the target frequency band update process, and the detection process stop process represent four stages. The next stage will be executed only after the previous stage is completed.

[0033] In this embodiment, in the process of determining the target frequency band, the sequence is as follows: first, a communication detection is performed on the first device, and then the value of each communication index of each sub-frequency band of the first device is calculated, and then the target frequency band and the non-target frequency band are determined according to the value of each communication index of each sub-frequency band of the first device. If the target frequency band cannot be determined, a communication detection is performed on the second device, and then the value of each communication index of each sub-frequency band of the second device is calculated, and then the target frequency band and the non-target frequency band are determined according to the value of each communication index of each sub-frequency band of the first device and the second device. If the target frequency band cannot be determined, the communication detection is continued on the next device until the target frequency band is determined. Generally speaking, at least two devices are required to obtain the target frequency band. In S101, for a device, generally only one step of performing communication detection on the frequency band supported by the device and determining several sub-frequency bands is required. If the target frequency band is not determined, only the next device needs to perform communication detection on the frequency band supported by the device and determine several sub-frequency bands, and there is no need to repeatedly detect the device that has been detected for communication.

[0034] In this embodiment, the communication detection is performed through data transmission, so the communication index can be an index such as packet loss rate, delay, transmission speed, etc. The value of the communication index of each sub-band of each device is independent and determined by the communication detection at that time.

[0035] In this embodiment, the target frequency band is determined, and the remaining frequency bands are non-target frequency bands, that is, the non-target frequency bands are determined based on the target frequency bands. The number of target frequency bands is indefinite, and the number of non-target frequency bands is also indefinite.

[0036] In this embodiment, after the target frequency band is determined, the subsequent devices that need to perform communication detection are all called new devices. The new devices are only different from the devices in the target frequency band determination process, and the setting parameters remain unchanged. In the target frequency band detection process, only one new device is targeted. This is different from the target frequency band determination process. The target frequency band determination process is to perform communication detection on each device one by one until the target frequency band is determined. The entire target frequency band determination process includes several devices, while the target frequency band detection process only performs communication detection on all target frequency bands and some non-target frequency bands of a new device.

[0037] In this embodiment, if the new device is the first new device after the target frequency band is determined, the new device does not exist as the previous new device. At this time, it is not necessary to select a non-target frequency band interval that is not completely the same as the non-target frequency band interval of the previous new device. Generally, the non-target frequency band interval is directly selected. Not completely the same means that there are parts that are the same and parts that are not the same. Since the first new device has no reference, the selected sampling frequency band does not need to meet the setting of not completely the same. The bandwidth of the sampling frequency band of the new device is the same.

[0038] In this embodiment, the first preset number can be set to 10 or any other integer. For example, if it is set to 10, it can be understood that the target frequency band will be updated after executing 10 target frequency band detection processes. Updating the target frequency band means redefining the target frequency band. At this time, the detection process stops, and all detected devices will no longer be considered new devices. After the target frequency band is redetermined, the subsequent devices that need to perform communication detection are called new devices. It should be noted that updating the target frequency band is only a step. Even if the updated target frequency band is still the original target frequency band, it still means that the target frequency band has been redetermined.

[0039] In this embodiment, the setting parameters of the device may be process parameters, such as the rated power and frequency band of the device. The values ​​of the device housing, volume, etc. that are not related to communication do not belong to the setting parameters. The completion of the detection process can be understood as no new device needs to be tested for communication.

[0040] The embodiment of the present invention provides a production test method for reducing the number of tests by performing communication detection on the frequency bands supported by the device; determining the target frequency band and the non-target frequency band according to the result of the communication detection; after determining the target frequency band, performing communication detection on all the target frequency bands of the new device; selecting a non-target frequency band interval that is not completely the same as the non-target frequency band interval of the previous new device from the non-target frequency band of the new device, and recording it as a sampling frequency band; performing communication detection on the sampling frequency band of the new device; when the cumulative detection number of the new device reaches the first preset number, the target frequency band is updated according to the communication detection results of the target frequency band and the sampling frequency band of each new device, and after updating the target frequency band, the communication detection of the subsequent device is continued until the setting parameters of the device change or the detection process is completed. In this way, the frequency bands supported by a small number of devices are detected first, and after determining the target frequency band, all the target frequency bands of the subsequent devices are detected, and the sampling frequency bands of the subsequent devices are selected from the non-target frequency bands, and the sampling frequency bands detected by each subsequent device are not completely the same so that the non-target frequency band intervals in the entire non-target frequency band can be sampled. This greatly reduces the number of tests and improves efficiency. At the same time, all equipment is tested to ensure the quality of the test, solving the problem of both efficiency and quality being incompatible during the testing process of communication equipment.

[0041] In one embodiment, the performing communication detection on the frequency band supported by the device and determining a plurality of sub-frequency bands includes:

[0042] S201, for each device, obtaining an arbitrary value within a preset range as a selected bandwidth, and selecting a communication frequency band from the starting point of the frequency band supported by the device according to the selected bandwidth;

[0043] S202, reacquiring an arbitrary value within a preset range as a selected bandwidth, and selecting a communication frequency band according to the selected bandwidth as a starting point at the end point of the previous communication frequency band;

[0044] S203, repeat S202 until the end point of the communication frequency band is the end point of the frequency band supported by the device;

[0045] S204, for each communication frequency band, sending detection data to the device through the communication frequency band, receiving the return data of the device to form a communication detection result;

[0046] S205, dividing the frequency band supported by the device into a plurality of sub-frequency bands according to the first preset bandwidth;

[0047] S206: For each sub-frequency band, record the result of the communication detection of the communication frequency band into which the sub-frequency band is placed as the result of the communication detection of the sub-frequency band.

[0048] In this embodiment, S201-S203 essentially divides the frequency band supported by the device into several communication frequency bands, and the bandwidth of the communication frequency band is the selected bandwidth. The preset range can be set to a range between the minimum operating communication bandwidth and five times the minimum operating communication bandwidth.

[0049] In this embodiment, the frequency bands supported by the device may be continuous or discontinuous. If they are discontinuous, S201 to S203 are performed separately for each continuous frequency band.

[0050] In this embodiment, in S203, the communication frequency band can only be an interval of the frequency bands supported by the device. If the last remaining frequency band of the frequency bands supported by the device is smaller than the selected bandwidth of the last communication frequency band, the last remaining frequency band of the frequency bands supported by the device is directly set as the last communication frequency band.

[0051] In this embodiment, the return data includes the time and data volume of the device receiving the detection data, the time and data volume of the device sending the return data, etc. The process of communication detection is to send the detection data and receive the return data. Therefore, the result of the communication detection is the received return data.

[0052] In this embodiment, the first preset bandwidth is the minimum operating communication bandwidth, so the bandwidth of the sub-band obtained is the minimum operating communication bandwidth, and the bandwidths of the sub-bands are the same, except for the last sub-band. The last sub-band may be smaller than the normal sub-band because the remaining bands of the bands supported by the device are insufficient.

[0053] In this embodiment, the bandwidth of the communication frequency band must be greater than or equal to the bandwidth of the sub-frequency band. For example, communication frequency band 1 includes 2 sub-frequency bands. The advantage of this is that it is not necessary to perform communication tests on both sub-frequency bands. Only communication test on communication frequency band 1 is required. The result of communication test on communication frequency band 1 can be regarded as the result of communication test on 2 sub-frequency bands, which indirectly reduces the number of detection times of a device. If the sub-frequency band is between two communication frequency bands, the average value of the communication test results of the two communication frequency bands is used as the result of communication test on the sub-frequency band.

[0054] In one embodiment, the step of calculating the values ​​of each communication indicator for each sub-band of each device according to the communication detection result of each device includes:

[0055] For each sub-band of each device, determine the time t1 and data volume B1 of sending detection data to the device, the time t2 and data volume B2 of receiving the return data of the device, the time t3 and data volume B3 of the device receiving the detection data, and the time t4 and data volume B4 of sending the return data by the device according to the result of the communication detection of the sub-band;

[0056] Depend on Determine the packet loss rate of the sub-band of the device;

[0057] Depend on Determine the latency of the device in the sub-band;

[0058] Depend on Determines the transmission speed of this device for this sub-band.

[0059] In this embodiment, the packet loss rate, delay, and transmission speed are all independent communication indicators, and the number of communication indicator values ​​of a device is the number of frequency bands multiplied by the number of communication indicators.

[0060] In this embodiment, for sub-bands in the same communication frequency band, since the same data is used, the packet loss rate, delay, and transmission speed are all the same. For a sub-band falling between two communication frequency bands, the packet loss rate of the sub-band can be the average of the packet loss rates, delays, and transmission speeds of the two adjacent sub-bands.

[0061] In one embodiment, determining the target frequency band and the non-target frequency band according to the value of each communication indicator of each sub-frequency band of each device includes:

[0062] S401, for each sub-band, by Get the first fluctuation value of the sub-band, by The second fluctuation value of the sub-band is obtained by Obtaining the third fluctuation value of the sub-frequency band;

[0063] S402, by The first volatility of the sub-band is obtained by The first deviation rate of the sub-band is obtained by The second volatility of the sub-band is obtained by The second deviation rate of the sub-band is obtained by The third volatility of the sub-band is obtained by Obtaining a third deviation rate of the sub-frequency band;

[0064] S403, determining whether the first volatility, the second volatility or the third volatility is greater than a preset volatility, if so, marking the sub-frequency band as a key frequency band, if not, determining whether the first deviation rate, the second deviation rate or the third deviation rate is greater than a preset deviation rate;

[0065] S404, if the first deviation rate, the second deviation rate or the third deviation rate is greater than a preset deviation rate, marking the sub-frequency band as a key frequency band;

[0066] S405, determining whether all sub-bands of the device have been determined, and if so, determining whether a key frequency band appears;

[0067] S406, if a key frequency band appears, starting from the first key frequency band, determine whether the key frequency band and the next key frequency band overlap, and if so, merge the overlapping key frequency bands into one key frequency band;

[0068] S407, if the key frequency band and the next key frequency band do not intersect, determine whether the bandwidth between the key frequency band and the next key frequency band is less than the second preset bandwidth, if so, retain the key frequency band corresponding to the largest volatility among the first volatility, the second volatility and the third volatility of the key frequency band and the next key frequency band as the key frequency band, and unmark the other key frequency band;

[0069] S408, repeat S406-S407 until all the key frequency bands are judged;

[0070] S409, if the key frequency band does not appear, wait for the next device to perform communication detection and then execute S401-S408;

[0071] S410, determining the key frequency band as the target frequency band, and determining the frequency bands other than the target frequency band as non-target frequency bands;

[0072] Where n is the number of devices that have been tested for communication, i is the serial number of the device that has been tested for communication, j is the serial number of the sub-band, j starts counting from 1, and a ij is the packet loss rate of the jth sub-band of the i-th device, T ij is the delay of the jth sub-band of the ith device, v ij is the transmission speed of the jth sub-band of the i-th device, x 1j is the average packet loss rate of the jth sub-band, x 2j is the average delay of the jth sub-band, x 3j is the average transmission speed of the jth sub-band, is the first fluctuation value of the jth sub-band, is the second fluctuation value of the jth sub-band, is the third fluctuation value of the j-th sub-frequency band.

[0073] In this embodiment, Get the average packet loss rate of the jth sub-band, by Get the average value of the delay of the jth sub-band, by The average value of the transmission speed of the j-th sub-frequency band is obtained.

[0074] In this embodiment, the volatility is the degree of data fluctuation. The greater the volatility, the higher the degree of fluctuation. The deviation rate is the degree of deviation of the nth device from the fluctuation value. The nth device is the device that has recently performed communication detection. nj is the packet loss rate of the jth sub-band of the nth device, T nj 、v nj Similarly. If the fluctuation of the sub-band is low and the deviation of the nth device is low, it means that the stability rate of the communication detection of the sub-band is very high. In subsequent devices, it is not necessary to frequently detect the sub-band. A random inspection method can be used, that is, the sub-band is a non-target band; if the fluctuation of the sub-band is high or the deviation of the nth device is high, it means that the stability rate of the communication detection of the sub-band is not high. In subsequent devices, it is necessary to frequently detect the sub-band. A full inspection method can be used, that is, the sub-band is a target band.

[0075] In this embodiment, for a sub-frequency band, as long as one of the first volatility, the second volatility and the third volatility is greater than the preset volatility, the sub-frequency band can be recorded as a key frequency band, and as long as one of the first deviation rate, the second deviation rate or the third deviation rate is greater than the preset deviation rate, the sub-frequency band can also be recorded as a key frequency band. The preset volatility can be set to any value between 5% and 10%, and the preset deviation rate can be set to any value between 5% and 10%. The difference between the volatility and the deviation rate is that the volatility is for all devices that have undergone communication detection, while the deviation rate is only for the device that has undergone the latest communication detection.

[0076] In this embodiment, in S406, the crossed key frequency bands will only have one end point of the two key frequency bands that is the same, that is, the end point of the previous key frequency band is the starting point of the next key frequency band. If they are merged into one key frequency band, the first volatility, the second volatility and the third volatility of this key frequency band need to be recalculated.

[0077] In this embodiment, there can be multiple target frequency bands, but the target frequency bands cannot be too close, so a second preset bandwidth needs to be set, and the second preset bandwidth can be set between 1-5 times of the first preset bandwidth, and is generally set to 2 times. After the key frequency band is unmarked, the frequency band is no longer a key frequency band.

[0078] In this embodiment, if the key frequency band does not appear, S409 is executed until the key frequency band appears. Each time S409 is executed, the number of devices that have been detected for communication is increased by 1, that is, n plus 1.

[0079] In one embodiment, the performing communication detection on all target frequency bands of the new device includes:

[0080] For each target frequency band, setting a plurality of first test frequency points in the target frequency band according to a third preset bandwidth;

[0081] Numbering the first test frequency point;

[0082] Determine whether the new device is the first new device, if so, select the first first test frequency point and select a first test frequency point every other preset value, and record the selected first test frequency point as the target frequency point;

[0083] If the new device is not the first new device, the number of the target frequency point of the target frequency band of the last new device is obtained, and the first test frequency point corresponding to the number plus 1 is obtained as the target frequency point;

[0084] Send detection data to new devices via target frequency;

[0085] Receive the return data of the new device through the target frequency.

[0086] In this embodiment, the third preset bandwidth may be the first preset bandwidth. Generally speaking, the starting frequency point and the ending frequency point of the target frequency band are also recorded as test frequency points, so the number of test frequency points is the number of sub-frequency bands plus 1.

[0087] In this embodiment, the preset value can be set according to the number of first test frequencies. Generally, one third of the number of first test frequencies can be subtracted from 1 and rounded. For example, if there are 9 first test frequencies, the preset value can be set to 2. Then the first test frequencies selected by the first new device are numbered 1, 4, and 7. The first test frequencies selected by the second new device are numbered 2, 5, and 8. The first test frequencies selected by the third new device are numbered 3, 6, and 9. The first test frequencies selected by the fourth new device are numbered 1, 4, and 7. And so on for new devices thereafter. To obtain the first test frequency corresponding to the number plus 1, it is necessary to determine whether the number plus 1 exists. If not, the cycle is restarted from the first number. For example, the first test frequency numbered 9 is selected by the third new device, and the first test frequency numbered 10 should be selected by the fourth new device, but the first test frequency numbered 10 does not exist, so the cycle is restarted from the first test frequency numbered 1.

[0088] In one embodiment, selecting a non-target frequency band interval that is not completely the same as the non-target frequency band interval of the previous new device from the non-target frequency band of the new device, recorded as a sampling frequency band, includes:

[0089] Setting a plurality of non-target sub-frequency bands in the non-target frequency band according to the fourth preset bandwidth;

[0090] Numbering non-target sub-bands;

[0091] Determine whether the new device is the first new device. If so, select a second preset number of consecutive non-target sub-frequency bands according to the numbering sequence to form a non-target frequency band interval, and record the non-target frequency band interval as a sampling frequency band;

[0092] If the new device is not the first new device, a preset proportion of non-target sub-frequency bands in the non-target frequency band interval of the previous new device is retained, and several non-target sub-frequency bands that are completely different from the non-target sub-frequency bands of the previous new device are selected according to the numbering sequence to make the number of non-target sub-frequency bands reach a second preset number, and a non-target frequency band interval is established based on the selected non-target sub-frequency bands, and the non-target frequency band interval is recorded as the sampling frequency band.

[0093] In this embodiment, the fourth preset bandwidth may be the same as the second preset bandwidth.

[0094] In this embodiment, the second preset number is determined according to the number of sub-frequency bands and the first preset number to ensure that new devices within the first preset number can perform at least one communication detection on the non-target frequency band. For example, if the number of device sub-frequency bands is 15 and the first preset number is 10, excluding the target frequency band, the bandwidth of the non-target frequency band must be less than the bandwidth of 15 sub-frequency bands. In this case, the second preset number can be set to 3, so that at least one communication detection can be performed on the non-target frequency band in 10 new devices. Since the next new device needs to retain the preset proportion of non-target sub-frequency bands of the previous new device, the second preset number is at least 2. The second preset number can usually be set to 5.

[0095] In this embodiment, for example, the non-target sub-frequencies numbered 1, 2, and 3 selected by the first new device form a non-target interval as a sampling frequency band. Assuming the retention ratio is 1 / 3, the second new device retains the non-target sub-frequency numbered 3, and then selects the non-target sub-frequencies numbered 4 and 5 as the sampling frequency band. The third new device can retain the non-target frequency numbered 5, and so on. The non-target frequency bands that retain a preset ratio can generally select the non-target frequency bands with later numbers in the newly selected numbers. For example, for the second new device, the newly selected numbers are 4 and 5, and the latter number is 5.

[0096] In this embodiment, the preset ratio is set according to the second preset number to ensure that the value after the preset ratio is multiplied by the second preset number is an integer and does not exceed half of the second preset number. The simplest method is to use 1 divided by the second preset number as the preset ratio.

[0097] In one embodiment, performing communication detection on the sampling frequency band of the new device includes:

[0098] Setting a plurality of second test frequency points within the sampling frequency band according to the fifth preset bandwidth;

[0099] Sending detection data to the new device via a second test frequency point;

[0100] The return data of the new device is received via the second test frequency.

[0101] In this embodiment, the fifth preset bandwidth may be the same as the first preset bandwidth.

[0102] In this embodiment, since there are some non-target sub-frequency bands in the sampling frequency band that are the same as those in the previous new device, there are also some second test frequency points that are the same as the second test frequency points in the previous new device. This ensures the coordination of detection continuity and generation process continuity, and avoids the situation where the detection results are based on beat detection due to production progress.

[0103] In one embodiment, updating the target frequency band according to the communication detection result of the target frequency band and the sampling frequency band of each new device includes:

[0104] Combining the communication test results of the target frequency band and the sampling frequency band of each new device with the communication test results of each device in the target frequency band determination process;

[0105] Whether a new target frequency band is determined is determined according to the value of each communication indicator of each frequency band of each device. If so, the new target frequency band is updated and the non-target frequency band is updated synchronously.

[0106] In this embodiment, the combining process is the process of recalculating the supplementary data.

[0107] In this embodiment, if no new target frequency band appears, the original target frequency band is still used as the target frequency band, that is, no operation is performed, but the step of updating the target frequency band is also completed. Therefore, even if the target frequency band does not change, it is considered to be updated.

[0108] like Figure 3 As shown, in one embodiment, a production test device for reducing the number of tests is provided, which may specifically include:

[0109] Target frequency band determination module: performs communication detection on the frequency band supported by the device and determines several sub-frequency bands; calculates the value of each communication indicator of each sub-frequency band of each device according to the communication detection result of each device; determines the target frequency band and non-target frequency band according to the value of each communication indicator of each sub-frequency band of each device;

[0110] Target frequency band detection module: after determining the target frequency band, perform communication detection on all target frequency bands of the new device; select a non-target frequency band interval that is not completely the same as the non-target frequency band interval of the previous new device from the non-target frequency band of the new device, and record it as a sampling frequency band; perform communication detection on the sampling frequency band of the new device;

[0111] Target frequency band update module: determine whether the cumulative number of detections of new devices reaches a first preset number. If so, update the target frequency band according to the communication detection results of the target frequency band and the sampling frequency band of each new device. If not, execute the target frequency band detection module for the next new device and determine whether the cumulative number of detections of the new device reaches the first preset number.

[0112] Detection process stop module: Repeat the target frequency band detection module and the target frequency band update module until the setting parameters of the device are changed or the detection process is completed.

[0113] In this embodiment, each module of the production test device for reducing the number of tests is modularized in the method part of the present invention. For the specific explanation of each module, please refer to the corresponding content of the method part of the present invention, and the embodiment of the present invention will not be repeated here.

[0114] In one embodiment, a production test system for reducing the number of tests is provided, which may specifically include: a computer device and a product device;

[0115] The computer device is connected to the product device and is used to perform the steps of the above-mentioned production test method for reducing the number of tests;

In this way, the frequency bands supported by a small number of devices are detected first, and after determining the target frequency band, all the target frequency bands of the subsequent devices are detected, and for the non-target frequency band of the subsequent device, the sampling frequency band is selected from the non-target frequency band, and the sampling frequency band detected by each subsequent device is not completely the same so that the non-target frequency band interval in the entire non-target frequency band can be sampled. This greatly reduces the number of tests and improves efficiency. At the same time, all equipment is tested to ensure the quality of the test, solving the problem of both efficiency and quality being incompatible during the testing process of communication equipment.
