Description

Technical Field

[0001] The present invention relates to the field of wireless communication technology, and more particularly, to a wireless communication module inspection method and system for improving inspection efficiency. Background Art

[0002] Quality inspection of wireless modules primarily examines the signal spectrum quality of RF signals, testing indicators such as transmit power, frequency offset, multiple harmonics, and receiver sensitivity. Traditionally, wireless communication module or product inspections have been conducted using automated machines or semi-automated tooling. Wireless signal detection is achieved through air interface control signaling or modulation chip control. The RF detection terminal is connected to an RF instrument or RF testing tooling.

[0003] Prior to the technology of this invention, traditional wireless communication module spectrum template inspections required the use of expensive RF instruments to test whether the spectrum profile of the transmitted signal was at risk of exceeding the standard and whether there was excessive signal power leaking outside the main channel. During the inspection, testing each RF indicator item by item would take up a long inspection time, and the high price of RF instruments increased the cost of inspection. In addition, traditional wireless communication module inspection tooling only has the self-inspection function of the instrument itself, and lacks regular automated inspection methods for the link communication quality of the tooling. Long-term use may cause contact degradation, leading to the risk of batch quality inspection abnormalities. Summary of the Invention

[0062] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0063] Quality inspection of wireless modules primarily examines the signal spectrum quality of RF signals, testing indicators such as transmit power, frequency offset, multiple harmonics, and receiver sensitivity. Traditionally, wireless communication module or product inspections have been conducted using automated machines or semi-automated tooling. Wireless signal detection is achieved through air interface control signaling or modulation chip control. The RF detection terminal is connected to an RF instrument or RF testing tooling.

[0064] Prior to the technology of this invention, traditional wireless communication module spectrum template inspections required the use of expensive RF instruments to test whether the spectrum profile of the transmitted signal was at risk of exceeding the standard and whether there was excessive signal power leaking outside the main channel. During the inspection, testing each RF indicator item by item would take up a long inspection time, and the high price of RF instruments increased the cost of inspection. In addition, traditional wireless communication module inspection tooling only has the self-inspection function of the instrument itself, and lacks regular automated inspection methods for the link communication quality of the tooling. Long-term use may cause contact degradation, leading to the risk of batch quality inspection abnormalities.

[0065] In one embodiment of the present invention, a wireless communication module inspection method and system with improved inspection efficiency are provided. This solution addresses the reliance of traditional wireless module quality inspection methods on expensive radio frequency (RF) inspection instruments, enabling the use of ultra-low-cost RF testing equipment to meet wireless module quality inspection requirements.

[0066] According to a first aspect of an embodiment of the present invention, a wireless communication module inspection method with improved inspection efficiency is provided.

[0067] Figure 1 The present invention is a flowchart of a wireless communication module inspection method for improving inspection efficiency according to an embodiment of the present invention.

[0068] In one or more embodiments, preferably, the wireless communication module inspection method for improving inspection efficiency includes:

[0069] S101, sending four radio frequency signals with intervals of more than 10 MHz through a radio frequency power splitter;

[0070] S102: Detecting whether the fundamental wave power is normal based on a first signal among the four radio frequency signals;

[0071] S103, detecting whether there is severe frequency leakage based on the second signal and the third signal among the four radio frequency signals;

[0072] S104, judging whether harmonics meet standards based on a fourth signal among the four radio frequency signals;

[0073] S105, detecting signal quality by a minimum power generator, and detecting the receiving performance of the wireless communication module to be detected according to the minimum receiving RSSI value of the wireless communication module to be detected in the corresponding mode;

[0074] S106: Implement regular self-check of the radio frequency link by adding a standard radio frequency signal detection unit.

[0075] In an embodiment of the present invention, by using frequency division detection, the wireless modules to be tested in parallel are separated by a frequency of more than 10Mhz, and the performance test of the reception or transmission of multiple RF modules is carried out at the same time, thereby solving the problem of same-frequency time conflict during parallel detection. A RF power splitter is used to divide the RF signal to be tested into multiple parts, and multiple groups of RF detection channels are used to realize the multi-channel simultaneous detection function. The inspection tooling is extended to include a standard signal generating unit for self-test, which automatically self-tests the error of the tooling at regular intervals to see if there is any change, and automatically calibrates according to the deviation value. Compared with traditional wireless module production that mainly focuses on the control process, this solution focuses on upgrading the working methods of wireless RF quality inspection tooling, improving inspection efficiency and quality inspection accuracy without increasing costs.

[0076] Figure 2 The present invention is a flowchart of a wireless communication module inspection method for improving inspection efficiency in one embodiment of the present invention, in which four radio frequency signals with intervals of more than 10 MHz are sent through a radio frequency power splitter.

[0077] like Figure 2 As shown, in one or more embodiments, preferably, the sending of four RF signals with intervals of more than 10 MHz through the RF power splitter specifically includes:

[0078] S201, issuing a command to fix the wireless communication module on the test fixture;

[0079] S202 , transmitting the radio frequency signal to the radio frequency power splitter through the radio frequency probe, and multi-transmitting four radio frequency signals at a frequency interval of more than 10 MHz, wherein the four radio frequency signals include a first signal, a second signal, a third signal, and a fourth signal.

[0080] In an embodiment of the present invention, the wireless communication module is fixed on a test tool or related test fixture equipment, and the radio frequency signal is transmitted with low loss through a radio frequency probe or radio frequency connector, and the radio frequency signal is evenly divided into multiple paths through a radio frequency power splitter. Then, after passing through the radio frequency power splitter, the radio frequency signal is transmitted to several corresponding radio frequency signal test modules.

[0081] Figure 3 The present invention is a flowchart of a method for inspecting a wireless communication module to improve inspection efficiency, for detecting whether the fundamental wave power is normal based on a first signal among four radio frequency signals in accordance with an embodiment of the present invention.

[0082] like Figure 3 As shown, in one or more embodiments, preferably, detecting whether the fundamental wave power is normal according to the first signal of the four radio frequency signals specifically includes:

[0083] S301: Perform power compensation on the first signal to form a compensated first signal;

[0084] S302: Testing the center frequency of the compensated first signal to determine whether the corresponding power is greater than a preset fundamental wave power.

[0085] In an embodiment of the present invention, fundamental power spectrum detection is to detect the center frequency of the transmission frequency of the wireless communication module to be tested in this test item, and to detect whether the fundamental power is normal by testing the center frequency. The loss part of the RF power splitter needs to be compensated for with corresponding power, and the RF compensation should also include the loss of the RF probe contact part of the wireless communication module and the power loss at the transmission line and RF connector. For example, if the initial maximum transmission power is 20dBm, the insertion loss and line loss are 1dBm, and the power splitter loss is 14dBm, then the fundamental power after receiving the allowable fluctuation range should be greater than 4.5dBm to be qualified.

[0086] Figure 4 This is a flowchart of detecting whether there is severe frequency leakage based on the second signal and the third signal among the four radio frequency signals in a wireless communication module inspection method for improving inspection efficiency according to an embodiment of the present invention.

[0087] like Figure 4 As shown, in one or more embodiments, preferably, detecting whether there is severe frequency leakage based on the second signal and the third signal among the four RF signals specifically includes:

[0088] S401, taking a preset frequency upward from the center frequency point as a high-frequency adjacent frequency interval;

[0089] S402, taking a preset frequency downward from the center frequency point as a low-frequency adjacent frequency interval;

[0090] S403: Perform high-frequency monitoring based on the second signal, monitor the leakage power of adjacent frequency intervals of the high frequency, and determine whether it is lower than a preset power;

[0091] S404: Perform low-frequency monitoring according to the third signal, monitor the leakage power of the adjacent frequency interval of the low frequency, and determine whether it is lower than a preset power.

[0092] In an embodiment of the present invention, high and low frequency template detection is performed to determine whether the quality of the radio frequency spectrum meets the design requirements by detecting the adjacent frequency leakage power. Generally, the selection of high and low frequency points is related to the bandwidth of the transmitted signal. For example, in the example of the present invention, a bandwidth of 125kHz is selected, and the power of the center frequency ±500kHz is judged to be less than -40dBm to be qualified. The actual power should be determined by the characteristics of the detected signal. This method can be used to detect its key adjacent frequency leakage indicators. Note that this item can add more radio frequency detection modules to detect a more accurate template range.

[0093] Figure 5 The present invention is a flowchart of a method for inspecting a wireless communication module to improve inspection efficiency, for determining whether harmonics meet standards based on a fourth signal among four radio frequency signals, according to an embodiment of the present invention.

[0094] like Figure 5 As shown, in one or more embodiments, preferably, judging whether the harmonics meet the standards based on the fourth signal of the four RF signals specifically includes:

[0095] S501, determining all harmonics corresponding to the center frequency, and retaining the second harmonic therein;

[0096] S502: Perform a power analysis of the second harmonic according to the fourth signal to determine whether the second harmonic power meets the standard. If not, issue an event record.

[0097] In embodiments of the present invention, harmonic power detection utilizes this approach to detect multiple harmonic powers. For example, in this embodiment, the second harmonic of the signal to be detected is the frequency point that has the greatest impact on the fundamental signal. Therefore, the primary focus is on detecting the second harmonic power, with a passing requirement of 50dBm. The actual passing value for harmonic detection depends on the characteristics of the signal being detected. This method can be used to assess the quality of harmonics in mass production. Note that this option can also include signals of higher harmonics, such as the third and fourth harmonics.

[0098] Figure 6 This is a flowchart of a wireless communication module inspection method for improving inspection efficiency in an embodiment of the present invention, in which signal quality is detected by a minimum power generator, and the reception performance detection of the wireless communication module to be detected is implemented according to the minimum receiving RSSI value under the corresponding mode of the wireless communication module to be detected.

[0099] like Figure 6 As shown, in one or more embodiments, preferably, the signal quality is detected by a minimum power generator, and the reception performance detection of the wireless communication module to be detected is implemented according to the minimum received RSSI value in the corresponding mode of the wireless communication module to be detected, specifically including:

[0100] S601, according to the minimum receiving RSSI value in the corresponding mode of the wireless communication module to be detected;

[0101] S602: Add the minimum receiving RSSI value to the insertion loss, line loss, and power splitter loss in sequence to form the minimum generated signal output power;

[0102] S603, enabling the minimum power generator to emit the minimum generation signal output power to the radio frequency power splitter;

[0103] S604: The radio frequency power splitter feeds back the minimum generated signal output power to the wireless communication module.

[0104] In an embodiment of the present invention, a minimum power generator is used to test signal quality. Based on the minimum receive RSSI value of the wireless communication module under test in the corresponding mode, combined with insertion loss, line loss, and power splitter loss, the minimum power generator generates a corresponding output power to test the receiving performance of the wireless communication module under test. For example, in this embodiment of the present invention, the minimum signal receiving capability of the signal under test is -129dBm. With an allowable measurement error of 1dBm, the minimum power generator should output a test signal of -113dBm. To save costs, the wireless communication module can generate a minimum output power of -20dBm, placed in a mother-and-child shielding box, and attenuated to -113dBm by a power attenuator in the mother box. The actual harmonic detection is qualified.

[0105] Figure 7 This is a flowchart of a wireless communication module inspection method for improving inspection efficiency in one embodiment of the present invention, which implements periodic self-inspection of a radio frequency link by adding a standard radio frequency signal detection unit.

[0106] like Figure 7 As shown, in one or more embodiments, preferably, the periodic self-check of the radio frequency link is realized by adding a standard radio frequency signal detection unit, specifically including:

[0107] S701: When no wireless module to be detected is inserted, a standard radio frequency signal is sent through a radio frequency standard detection unit;

[0108] S702. Detect the receiving and transmitting performance of the full communication link of the quality inspection equipment through a stable feeder connection. The receiving and transmitting performance of the full communication link includes a stability test of the fundamental wave power and frequency, a test of the RF signal template detection capability, a harmonic detection function test, and a minimum power signal reception test.

[0109] S703. If the performance of the receiver and transmitter of the full communication link is normal, after the RF standard signal is detected, the calibration module is placed in the tooling to detect the contact error of the RF probe. The inspection of the transmission and reception signals is completed through the automated process of the host computer. If it is abnormal, an event record is issued.

[0110] In an embodiment of the present invention, a standard RF signal detection unit is added to achieve regular self-test of the RF link. The specific implementation process is that when the wireless module to be tested is not placed, a standard RF signal is sent through the RF standard detection unit, and the connection 5 is connected through a stable feeder to detect the receiving and transmitting performance of the full communication link of the quality inspection equipment, including the stability test of the fundamental power and frequency, the RF signal template detection capability test, the harmonic detection function test, the minimum power signal reception test, etc. After passing the RF standard signal detection, the calibration module is placed in the tooling, the contact error of the RF probe is detected, and the detection of the transmission and reception signals is completed through the host computer automation process.

[0111] According to a second aspect of an embodiment of the present invention, a wireless communication module inspection system with improved inspection efficiency is provided.
