Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a passive intermodulation positioning method and computer equipment. Background Art

[0002] Passive intermodulation refers to the nonlinear interaction between signals of different frequencies in electronic devices, which generates new frequency combinations. These new frequency combinations may be close to the frequencies of signals that the electronic devices need to receive, thus causing noise problems, reducing the signal-to-noise ratio of the received signal, causing the received signal to become blurred or distorted, and ultimately affecting the quality of signal reception. For example, as a complex electronic device, the internal circuits and components of a mobile phone often exhibit nonlinear characteristics. When signals of different frequencies exist at the same time, passive intermodulation noise is easily generated. In addition, during the development of mobile phones, the distance between the internal circuits and components of mobile phones is often very close and placed in a compact space. Such a design makes the interaction between different circuits and components inside the mobile phone more intensive and complex, increasing the probability and impact of passive intermodulation, and affecting the reception quality of mobile phone signals.

[0003] In related solutions, it is usually necessary to spend a lot of manpower and material resources to conduct a large number of tests and analyses to determine which circuits or components in the mobile phone may produce passive intermodulation, and it is also necessary to find the specific location where the passive intermodulation is produced to eliminate the noise impact of the passive intermodulation on the received signal. For example, by isolating the contact position or increasing the contact pressure to verify and eliminate the impact one by one, this passive intermodulation positioning method is inefficient.

[0018] It should be noted that the terms "first" and "second" in the specification, claims and drawings of the present application are used to distinguish similar objects rather than to describe a specific order or sequence.

[0019] It should also be noted that the method disclosed in the embodiments of the present application or the method shown in the flowchart includes one or more steps for implementing the method. Without departing from the scope of the claims, the execution order of multiple steps can be interchangeable with each other, and some of the steps can also be deleted.

[0020] Some embodiments will be described below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0021] During the circuit design or system design of electronic devices such as mobile phones and tablets, factors such as the presence of nonlinear devices in the circuit and poor circuit connections (for example, loose connections, poor contact, or oxidation in the circuit) may cause passive intermodulation. The noise caused by passive intermodulation may seriously affect the reception quality of electronic equipment signals. Among them, the generation of passive intermodulation requires the simultaneous satisfaction of nonlinear characteristics and frequency intermodulation conditions. The generation mechanism of passive intermodulation is that two (or more) transmission signals pass through nonlinear devices to generate intermodulation products (such as third-order intermodulation, fifth-order intermodulation, etc.). The intermodulation products fall into the receiving frequency band and interfere with the receiving signal of the electronic device. For example Figure 1As shown, the frequency range of the transmission band of the electronic device is 930MHz to 960MHz, wherein two different frequency transmission signals 930MHz and 950MHz pass through nonlinear devices to generate intermodulation products of third-order intermodulation (frequency is 910MHz). Since the frequency range of the receiving band of the electronic device is 890MHz to 915MHz, the transmission signals 930MHz and 950MHz pass through nonlinear devices to generate third-order intermodulation (frequency is 910MHz) and fall into the receiving band, generating passive intermodulation noise, thereby affecting the reception quality of the electronic device signal.

[0022] In the related passive intermodulation positioning scheme, it is often necessary to isolate the contact parts in the electronic device one by one, or to increase the contact pressure of the contact parts one by one, to verify whether each contact part in the electronic device is the part that causes passive intermodulation. This positioning method is time-consuming, requires a lot of manpower and material resources, and is inefficient.

[0023] In order to solve the problem of low efficiency of passive intermodulation positioning in related passive intermodulation positioning solutions, an embodiment of the present application provides a passive intermodulation positioning method and a computer device. The computer device divides the device under test into multiple partitions. In order to verify whether each partition is a part that is prone to passive intermodulation, for each partition, the computer device controls the device under test to transmit a first signal, and controls the preset signal generating device to transmit a second signal through a directional antenna to simulate the transmission of signals of different frequencies to each partition, and receives the first received signal fed back by the device under test, and establishes a first corresponding relationship between the first received signal and the corresponding partition. The computer device performs noise detection on the first received signal corresponding to each partition. If there is passive intermodulation noise in the first received signal, it is determined that the partition corresponding to the first received signal is the passive intermodulation generating part. The embodiment of the present application does not need to consume a lot of manpower and material resources to carry out a large number of tests, which effectively improves the efficiency of passive intermodulation positioning.

[0024] In some embodiments, the computer device includes one or more of a computer, a laptop, a PDA, a cloud server, etc. The device under test includes but is not limited to any one of a mobile phone, a tablet, and a laptop. The preset signal generating device includes but is not limited to any one of a signal generator and a signal conditioner, wherein the signal conditioner includes but is not limited to any one of a signal amplifier and a signal attenuator.

[0025] See also Figure 2 As shown in FIG. 1 , an example diagram of an application scenario of the passive intermodulation positioning method provided in an embodiment of the present application is shown. In some embodiments, the preset signal generating device may be a signal conditioner 300. Figure 2As shown, the computer device 100 is respectively connected to the device under test 200, the signal conditioner 300, and the directional antenna 400. The signal conditioner 300 and the directional antenna 400 are connected by cables or the like. In the process of implementing the passive intermodulation positioning of the device under test 200, the computer device 100 determines multiple partitions of the device under test 200 according to the preset partitioning rules. The computer device 100 controls the device under test 200 to transmit a first signal to each partition and the signal conditioner 300. Figure 2 As shown, the computer device 100 can control the built-in antenna in the device under test 200 to transmit the first signal A to the C partition of the device under test 200. The signal conditioner 300 receives the first signal and amplifies or attenuates the first signal to obtain a second signal. For each partition, the computer device 100 controls the signal conditioner 300 to send the second signal to the directional antenna 400. Then the computer device 100 can control the directional antenna 400 to send the second signal to each partition. Figure 2 As shown, the computer device 100 can control the directional antenna 400 to send the second signal B to the C partition of the device under test 200 .

[0026] In some embodiments, the directional antenna 400 is fixed to the slide rail 500, and the computer device 100 is in communication connection with the slide rail 500. The computer device 100 can control the slide rail 500 to move, thereby driving the directional antenna 400 to move, so as to control the directional antenna 400 to transmit the second signal to each partition.

[0027] In other embodiments, the computer device 100 may also drive the directional antenna 400 to move only by controlling the movement of the slide rail 500 to transmit the second signal to each partition without establishing a communication connection between the computer device 100 and the directional antenna 400.

[0028] In other embodiments, the directional antenna 400 may also be movably connected to the slide rail 500, and the computer device 100 may control the directional antenna 400 to move along the slide rail 500, so as to control the directional antenna 400 to transmit the second signal to each partition.

[0029] In some embodiments, the communication connection includes any one of a wired communication connection and a wireless communication connection. In the embodiments of the present application, the communication connection modes of the computer device 100 and the device under test 200, the signal conditioner 300, the directional antenna 400 and the slide rail 500, and the connection mode between the signal conditioner 300 and the directional antenna 400 are not limited.

[0030] In some embodiments, considering that the size of the device under test 200 may be relatively small, in order to improve the accuracy of passive intermodulation positioning, the directional antenna 400 may be a small directional mini antenna with relatively strong directional performance.

[0031] See also Figure 3 As shown, it is another example diagram of an application scenario of the passive intermodulation positioning method provided in an embodiment of the present application. In some embodiments, the preset signal generating device can also be a signal generator 600. Figure 3 As shown, the computer device 100 is respectively connected to the device under test 200, the signal generator 600, the directional antenna 400 and the slide rail 500. The signal generator 600 is connected to the directional antenna 400 via a cable or the like. The directional antenna 400 is fixedly connected to the slide rail 500. In the process of implementing the passive intermodulation positioning of the device under test 200, the computer device 100 determines multiple partitions of the device under test 200 according to the preset partitioning rules. Then, the computer device 100 controls the device under test 200 to transmit a first signal to each partition, such as Figure 3 As shown, the computer device 100 can control the built-in antenna in the device under test 200 to transmit the first signal A to the C partition of the device under test 200. The computer device 100 controls the signal generator 600 to generate a second signal and sends the second signal to the directional antenna 400. Then, the computer device 100 can control the directional antenna 400 to send the second signal to each partition of the device under test 200. Figure 3 As shown, the computer device 100 can control the directional antenna 400 to send the second signal B to the C partition of the device under test 200 .

[0032] In other embodiments, the computer device 100 may also drive the directional antenna 400 to move only by controlling the movement of the slide rail 500 to transmit the second signal to each partition without establishing a communication connection between the computer device 100 and the directional antenna 400.

[0033] See also Figure 4 As shown in FIG. 1 , it is a flowchart of the implementation of the passive intermodulation positioning method provided in an embodiment of the present application. The method is applied to a computer device. Figure 2 or Figure 3 Taking the computer device 100 in FIG. 1 as an example, the method includes the following steps.

[0034] S11: Determine multiple partitions of the device under test according to a preset partition rule.

[0035] In some embodiments, the preset partitioning rule may be to divide the device under test into M*N partitions, wherein M and N are both positive integers and M and N may be user-defined and may be the same value or different values.

[0036] In the process of realizing passive intermodulation positioning of mobile phones and other devices, since mobile phones and other devices have many internal parts and complex structures, it is difficult to easily locate which part is the passive intermodulation generating part. If each part is tested and verified one by one, missed detection and repeated detection may occur, thereby affecting the efficiency of passive intermodulation positioning. Therefore, the embodiment of the present application partitions the device to be tested according to preset partitioning rules, determines multiple partitions of the device to be tested, and can accurately and quickly realize passive intermodulation positioning of mobile phones and other devices by testing and verifying each partition, effectively reducing missed detection and repeated detection, and improving the efficiency of passive intermodulation positioning.

[0037] As an example, Figure 5 As shown, both M and N are 20, that is, the device under test is divided into 20*20 partitions. In some embodiments, (m, n) can be used to represent the position of any partition in the M*N partitions, where m∈(0, M), n∈(0, N), and m and n are both integers. For example, Figure 5 The position of the C partition in can be represented as (6, 8). In some embodiments, the C partition can also be represented by a (6, 8) partition.

[0038] S12: For each partition, control the device under test to transmit a first signal and control the preset signal generating device to transmit a second signal through a directional antenna, receive a first receiving signal fed back by the device under test, and establish a first corresponding relationship between the first receiving signal and the corresponding partition.

[0039] In some embodiments, the device under test itself has a wireless communication function, which can convert electrical signals into wireless signals and transmit them to each partition through a built-in antenna, processor, radio frequency module, etc. The preset signal generating device is used as an excitation source to generate a passive intermodulation excitation signal, that is, a second signal, which can be used to assist passive intermodulation positioning, etc.

[0040] In some embodiments, to ensure the accuracy of passive intermodulation positioning, for each partition, the computer device controls the first signal transmitted by the device under test and controls the preset signal generating device to transmit the second signal through the directional antenna as a transmission signal of the same frequency band.

[0041] In some embodiments, the preset signal generating device includes but is not limited to any one of a signal generator, a signal amplifier, and a signal attenuator. Considering the size of the device to be tested (such as a mobile phone), in order to avoid the second signal generating an impact area that is too large and affects the accuracy of passive intermodulation positioning, the directional antenna can be a small directional mini antenna with strong directional performance.

[0042] In some embodiments, the computer device may send a control instruction to the directional antenna to adjust the directional angle, parameters, etc. of the directional antenna so that the directional antenna transmits the second signal to each partition.

[0043] In some embodiments, the partitions in the device under test that produce passive intermodulation are located. For each partition, the computer device controls the device under test to transmit a first signal, and controls the preset signal generating device to transmit a second signal in the same frequency band as the first signal through a directional antenna to simulate transmitting signals of different frequencies to each partition. It is detected whether any partition is a location where passive intermodulation is produced, that is, after the computer device controls the device under test to transmit a first signal to any partition, and controls the preset signal generating device to transmit a second signal to any partition through a directional antenna, whether there is passive intermodulation noise in the first received signal of the device under test. Therefore, the computer device needs to establish a corresponding relationship between the first received signal and the corresponding partition. The computer device determines the first received signal with passive intermodulation noise. According to the corresponding relationship between the first received signal and the corresponding partition, the partition that produces passive intermodulation can be determined.

[0044] In some embodiments of the present application, the computer device can adjust the position of the directional antenna by controlling the movement of the slide rail where the directional antenna is located, so that the second signal is transmitted to different partitions in the device under test through the directional antenna.

[0045] In some embodiments, if the position of the directional antenna is fixed, the transmission distance of the second signal transmitted by the directional antenna to each partition of the device under test may be different, which may lead to inaccurate results of passive intermodulation positioning. Figure 2 or Figure 3 As shown, the directional antenna can be fixed on the slide rail, and the computer device drives the directional antenna to move by controlling the movement of the slide rail, so as to control the directional antenna to transmit the second signal to each partition of the device under test and ensure that the transmission distance of the second signal to each partition is the same, thereby improving the accuracy of passive intermodulation positioning.

[0046] In other embodiments, a directional antenna may be movably connected to the slide rail, and the computer device may control the directional antenna to move along the slide rail to control the directional antenna to transmit a second signal to each partition of the device under test and ensure that the transmission distance of the second signal to each partition is the same.

[0047] In some embodiments of the present application, the preset signal generating device includes a signal generator, and controlling the preset signal generating device to transmit the second signal through a directional antenna includes: controlling the signal generator to generate the second signal; and controlling the directional antenna communicatively connected to the signal generator to transmit the second signal.

[0048] In some embodiments, Figure 3As shown, the preset signal generating device may be a signal generator. In the process of controlling the preset signal generating device to transmit the second signal through the directional antenna, the computer device may control the signal generator to generate a second signal of a certain power and a certain frequency band, and control the signal generator to send the generated second signal to the directional antenna, so as to send the second signal to each partition of the device under test through the directional antenna.

[0049] In some embodiments, the computer device may send a control instruction to the directional antenna to adjust the direction angle and parameters of the directional antenna to control the directional antenna to transmit the second signal to each partition of the device under test.

[0050] In some embodiments of the present application, the preset signal generating device includes a signal regulator, and controlling the preset signal generating device to transmit a second signal through a directional antenna includes: controlling the signal regulator to adjust the first signal to obtain a second signal; and controlling the directional antenna communicatively connected to the signal regulator to transmit the second signal.

[0051] In some embodiments, Figure 2 As shown, the preset signal generating device may also be a signal conditioner, wherein the signal conditioner may be a signal amplifier or a signal attenuator.

[0052] In some embodiments, the computer device can control the device under test to transmit the first signal to each partition, and at the same time, send the first signal to the signal conditioner. The signal conditioner can amplify or attenuate the first signal after receiving the first signal to obtain a second signal. Then, the computer device controls the signal conditioner to send the second signal to the directional antenna, so that the second signal is sent to each partition of the device under test through the directional antenna.

[0053] In some embodiments of the present application, before controlling the device under test to transmit a first signal and controlling the preset signal generating device to transmit a second signal through a directional antenna, it also includes: determining a first transmission power of the first signal according to a first preset power range and a first power adjustment sequence; and determining a second transmission power of the second signal according to a second preset power range and a second power adjustment sequence.

[0054] In some embodiments, one of the characteristics of passive intermodulation is that it has a threshold effect, that is, the transmission power of the two (or more) transmission signals that produce intermodulation under the interaction needs to reach the threshold power (for example, 20dBm) of the nonlinear device to produce passive intermodulation, and the intermodulation products of the two (or more) transmission signals that produce intermodulation will fall into the receiving band, generating passive intermodulation noise, and interfering with the received signal. If the transmission power of the two (or more) transmission signals that produce intermodulation under the interaction is low (for example, below 18dBm, not reaching the threshold power), the intermodulation products of the two (or more) transmission signals that produce intermodulation will fall into the noise floor and will not interfere with the received signal. Therefore, before controlling the device under test to transmit the first signal and controlling the preset signal generating device to transmit the second signal through the directional antenna, the computer device also needs to determine the first transmission power corresponding to the first signal and the second transmission power corresponding to the second signal to ensure that the transmission power under the action of the first signal and the second signal can exceed the threshold power of the corresponding partition, so that the partition that produces passive intermodulation can be located. And because if the transmission power of the first signal and the second signal is greater than the maximum transmission power of the device under test, other types of noise besides passive intermodulation noise may be generated, affecting the accuracy of passive intermodulation positioning, therefore, when the computer device controls the device under test to transmit the first signal and controls the preset signal generating device to transmit the second signal through the directional antenna, the transmission power of the first signal and the second signal should be controlled to be less than or equal to the maximum transmission power of the device under test.

[0055] In some embodiments, since different partitions have different threshold powers for generating passive intermodulation, in order to accurately detect all partitions that may generate passive intermodulation, the user can determine the first preset power range corresponding to the first signal and the second preset power range corresponding to the second signal through pre-test training, so that the transmission power under the action of the first signal and the second signal can cover the threshold power for generating passive intermodulation in each partition, and can ensure that the transmission power of the first signal and the second signal are less than or equal to the maximum transmission power of the device under test.

[0056] In some embodiments, since the threshold powers for passive intermodulation in different partitions are different, the computer device can adjust the transmission power of the first signal and the second signal in a preset power range according to a preset adjustment order, so that the transmission power under the action of the first signal and the second signal increases or decreases to cover the threshold power for passive intermodulation in each partition. In one embodiment, the computer device can adjust the transmission power of the first signal and the second signal in a preset power range according to a preset adjustment order, so that the transmission power under the action of the first signal and the second signal covers the threshold power for passive intermodulation in each partition in an increasing order.

[0057] In some embodiments, the preset power range includes a first preset power range and a second preset power range, and the preset adjustment sequence includes a first power adjustment sequence and a second power adjustment sequence. The computer device can adjust the transmit power of the first signal and the second signal in the preset power range according to the preset adjustment sequence, so that the transmit power under the action of the first signal and the second signal covers the threshold power of each partition to generate passive intermodulation in ascending order. That is, the computer device can adjust the first signal in the first preset power range according to the first power adjustment sequence and adjust the second signal in the second preset power range according to the second power adjustment sequence, so that the transmit power under the action of the first signal and the second signal can cover the threshold power of each partition to generate passive intermodulation in ascending order. For example, the computer device can control the first transmit power of the first signal to remain unchanged, and gradually adjust the second signal in the second preset power range in an ascending order; or control the second transmit power of the second signal to remain unchanged, and gradually adjust the first signal in the first preset power range in an ascending order; or adjust the first signal in the first preset power range, and adjust the second signal in the second preset power range, so that the transmit power under the action of the first signal and the second signal can gradually cover the threshold power of each partition to generate passive intermodulation in an ascending order.

[0058] S13: According to the first corresponding relationship, determine, from the plurality of first received signals, a partition corresponding to a first received signal having passive intermodulation noise as a passive intermodulation generating location.

[0059] In some embodiments, the computer device determines whether any partition is a partition that generates passive intermodulation, that is, after controlling the device under test to transmit a first signal to the any partition and controlling the preset signal generating device to transmit a second signal to the any partition through a directional antenna, detects whether there is passive intermodulation noise in the first received signal of the device under test. If it is determined that there is passive intermodulation noise in the first received signal, the computer device can determine that any partition corresponding to the first received signal generates passive intermodulation, and can determine any partition corresponding to the first received signal as a passive intermodulation generating location.

[0060] In a passive intermodulation positioning method provided in an embodiment of the present application, in order to facilitate the accurate positioning of the passive intermodulation generating part of the device under test that generates passive intermodulation noise, the computer device partitions the device under test according to the preset partitioning rules, and determines multiple partitions of the device under test. For each partition, the computer device controls the device under test to transmit a first signal, and controls the preset signal generating device to transmit a second signal through a directional antenna to simulate the transmission of signals of different frequencies to each partition. For each partition, after the computer device transmits signals of different frequencies, it receives the first received signal fed back by the device under test, and establishes a first corresponding relationship between the first received signal and the corresponding partition. By performing noise detection on the first received signal corresponding to each partition, the partition corresponding to the first received signal with passive intermodulation noise is determined from multiple received signals as the passive intermodulation generating part. The embodiment of the present application does not require a large amount of manpower and material resources to carry out a large number of tests, and effectively improves the efficiency of passive intermodulation positioning.

[0061] In some embodiments of the present application, after determining, according to the first corresponding relationship, a partition corresponding to a first received signal having passive intermodulation noise from multiple first received signals as a passive intermodulation generation site, it also includes: generating prompt information according to the passive intermodulation generation site, the prompt information being used to prompt a user of the location of the passive intermodulation generation site, and prompting the user to maintain the passive intermodulation generation site.

[0062] In some embodiments, after determining, according to the first corresponding relationship, from a plurality of first received signals, the partition corresponding to the first received signal having passive intermodulation noise as the passive intermodulation generating part, the computer device may also generate prompt information, the prompt information including the location information of the passive intermodulation generating part, etc. The computer device may send the prompt information to the user terminal or display the prompt information through the display interface in the computer device to prompt the user of the location of the passive intermodulation generating part. The user receives the prompt information through the display interface or the user terminal, and may maintain the passive intermodulation generating part according to the prompt information.

[0063] In some embodiments, after determining the passive intermodulation generating location, the computer device may also issue a voice reminder to remind the user to perform maintenance on the passive intermodulation generating location in a timely manner.

[0064] In some embodiments, after the user performs maintenance on the passive intermodulation generating part, the user may send maintenance information to the computer device through the user terminal, or trigger an upload instruction through the display interface in the computer device to upload the maintenance information.

[0065] In some embodiments of the present application, the first signal and the second signal are broadband signals. After it is determined that the maintenance of the passive intermodulation generating part is completed according to the received maintenance information, the device under test is controlled to send a broadband signal with a maximum transmission power to all partitions; the second received signal of the device under test is detected; if there is passive intermodulation noise in the second received signal, the first transmission power of the first signal is adjusted according to the first preset power range and the first power adjustment sequence, and for each partition, the device under test is controlled to transmit the adjusted first signal and the preset signal generating device is controlled to transmit the second signal through the directional antenna, and a third received signal fed back by the device under test is received, and a second corresponding relationship between the third received signal and the corresponding partition is established; according to the second corresponding relationship, the partition corresponding to the third received signal with passive intermodulation noise is determined from multiple third received signals as the passive intermodulation generating part.

[0066] In some embodiments, the first signal and the second signal are broadband signals in the same frequency band.

[0067] In some embodiments, after determining that the maintenance of the passive intermodulation generating part is completed according to the received maintenance information, the computer device can control the device under test to send a broadband signal with maximum transmission power to all partitions, and detect whether there is passive intermodulation noise in the second received signal of the device under test. If there is passive intermodulation noise in the second received signal, the computer device determines that there is still a part of the device under test that generates passive intermodulation. Considering that the transmission power under the current first signal and the second signal may be less than the threshold power for some partitions to generate passive intermodulation, the computer device can adjust the first transmission power of the first signal according to the first preset power range and the first power adjustment sequence by controlling the second transmission power of the second signal to remain unchanged, so as to increase the transmission power under the action of the first signal and the second signal. Then, for each partition, the computer device controls the device under test to transmit the adjusted first signal and controls the preset signal generating device to transmit the second signal through the directional antenna, and receives the third received signal fed back by the device under test, and establishes a second corresponding relationship between the third received signal and the corresponding partition; according to the second corresponding relationship, the partition corresponding to the third received signal with passive intermodulation noise is determined from multiple third received signals as the passive intermodulation generating part.

[0072] In some embodiments, if it is determined that there is passive intermodulation noise in the second received signal, the computer device determines that there are still parts in the device under test that produce passive intermodulation. Considering that the transmission power under the current first signal and the second signal is less than the threshold power for some partitions to produce passive intermodulation, the computer device cannot effectively detect it even if some partitions may produce passive intermodulation. At this time, the computer device can also control the first transmission power corresponding to the first signal to remain unchanged, and adjust the power of the second signal according to the second preset power range and the second power adjustment sequence to increase the transmission power under the action of the first signal and the second signal. Then, for each partition, the computer device can control the device under test to transmit the first signal and control the preset signal generating device to transmit the adjusted second signal through the directional antenna, and receive the fifth received signal fed back by the device under test, and establish a fourth corresponding relationship between the fifth received signal and the corresponding partition; according to the fourth corresponding relationship, the partition corresponding to the fifth received signal with passive intermodulation noise is determined from multiple fifth received signals as the passive intermodulation generating part.
