[0002] Conducted interference is common in electronic equipment. Interference can be transmitted between circuits through physical connections such as power lines, signal lines, and ground lines, which can have an adverse effect on the normal operation and performance of electronic equipment, and may cause performance degradation, communication failures, or even system paralysis.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way. In addition, in the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more.

[0061] The signal conduction interference detection method provided in the embodiment of the present application can be performed by a signal conduction interference detection device, which can be implemented by software and / or hardware, and the device can be integrated in a device with a data processing function. Among them, the device can be an electronic device, and the electronic device can include but is not limited to such as a smart phone, a laptop computer, a tablet computer (Tablet Personal Computer, Tablet PC), a desktop computer, a server, an edge computing platform, etc. The embodiment of the present application does not limit the type of terminal device.

[0062] First, the application scenario of the detection method of signal conduction interference provided in the embodiment of the present application is introduced. Conducted interference is an important type of electromagnetic interference, which refers to the electromagnetic interference phenomenon caused by physical interfaces or shared power lines between circuits in electronic systems including electronic components, etc., and electronic devices such as mobile phones and tablets can be understood as electronic systems. Conducted interference can be transmitted through power lines, signal lines, ground lines or other physical connections, thereby seriously affecting the normal operation and performance of electronic devices. The impact of conducted interference on electronic devices is multifaceted. For example, it may cause the performance of electronic devices to decline, including signal distortion, increased noise and data errors, thereby affecting the working stability and reliability of the equipment. In severe cases, conducted interference may even cause equipment damage or system crash. In addition, conducted interference may also affect the integrity and accuracy of data transmission. Therefore, it is particularly important to solve the problem of conducted interference in electronic devices. In order to solve the problem of conducted interference in electronic devices, it is first necessary to detect signal conducted interference and determine the interference path and interference source.

[0063] At present, the common method for detecting signal conduction interference is for engineers to manually weld test points, detect abnormal points where sensitivity declines, and then gradually eliminate the circuits and components around the abnormal points to determine the specific path and source of the interference. However, this method is not only time-consuming and laborious, but also prone to many other external interference factors, resulting in low detection accuracy.

[0064] Based on this, the present application proposes a method for detecting signal conduction interference, which can be applied in the test scenario of electronic equipment, improve the efficiency of detecting signal conduction interference, and accurately locate the sub-RF path where the signal conduction interference occurs.

[0065] The signal conduction interference detection method provided by the present application is exemplarily described below through several specific embodiments.

[0066] Figure 1 A flowchart of a method for detecting signal conduction interference provided by an embodiment of the present application is provided. Figure 1 As shown, the following steps S110-S130 are included.

[0067] S110. Determine whether the electronic device is subject to conducted interference.

[0068] Among them, conducted interference refers to the phenomenon of coupling a signal on an electrical network to another electrical network through a conductive medium.

[0069] Specifically, in electronic systems such as electronic equipment, different circuits will interact with each other, and signal coupling will also occur through conductive media such as cables and wires, resulting in conducted interference. In addition to conducted interference, electronic equipment may also generate spatial coupling interference. Spatial coupling interference is interference caused by the coupling of electromagnetic energy through various channels. For example, capacitive coupling, electromagnetic coupling, etc. For different types of interference, appropriate methods can be adopted to suppress them. Therefore, in order to efficiently solve the interference problem of electronic equipment, it is necessary to first determine what type of interference the electronic equipment is subject to.

[0070] For example, see Figure 2 As shown, Figure 2 A schematic diagram of a radio frequency path provided for an embodiment of the present application, the core components of the radio frequency path include: a transceiver 21, a low noise amplifier (LNA) 22, a bandpass filter (SAWDUP) 23, a radio frequency switch 24, a dual in-line package (DIP) component 25, a test socket 26, an antenna 27, and a controller. A path switch is added to the radio frequency path for the key components. The path switch can be an SPST (Single Pole Single Throw) switch, which is used to control the on and off of the radio frequency path in electronic equipment. Among them, the transceiver is used to transmit a detection signal, and a SPST switch is set at the front and back ends of each device. From the antenna receiving end to the transceiver transmitting end, it includes: S1, S2, S3, S4, S5 and other five path switches. When the path switch is disconnected, the transmission of the detection signal is disconnected. In addition, multiple monitoring points are set in the radio frequency path to collect radio frequency conduction signals in real time. For example, monitoring points can be set near each switch and at a preset position of the radio frequency path. When S1 is disconnected, it is used to collect the signal transmitted to the test socket, when S2 is disconnected, it is used to collect the signal transmitted to the DIP, when S3 is disconnected, it is used to collect the signal transmitted to the RF switch, etc. The controller is used to control the opening or closing of the path switch.

[0071] It should be noted that Figure 2 The key components shown are components that may be included in the RF path. The RF path may also include more components and path switches, which are not limited in the embodiments of the present application.

[0072] In some embodiments, as an implementation method for determining whether the electromagnetic interference to an electronic device is conducted interference, the method includes: when the electronic device is subjected to electromagnetic interference, controlling the path switch used to connect the receiving end of the middle antenna to be disconnected, and controlling other path switches to be closed to form a first sub-RF path; determining whether the received signal parameters corresponding to the receiving end of the first sub-RF path are in an abnormal state; if so, determining that the electronic device is subjected to conducted interference.

[0073] The received signal parameters are parameters of the received detection signal, which may be level value RSSI, frequency, amplitude, phase and other parameters.

[0074] Specifically, combined Figure 2 As shown, when the electronic equipment is subjected to electromagnetic interference during the test, it is first confirmed whether it is caused by conducted interference or spatial coupling. In the default state, all path switches are closed normally, and the antenna receiving end receives the test signal. If the received signal parameters are abnormal, the controller controls the path switch S1 to be disconnected. At this time, if it is abnormal, it is determined that the electronic equipment is subjected to conducted interference.

[0075] For example, in the default state, all path switches are normally closed, and the antenna receiving end receives the test signal. If the level value of the received signal is abnormal, the controller controls the path switch S1 to be disconnected, and determines whether the level value of the test signal received at this time is abnormal. If it is abnormal, it is determined that the electronic device is subject to conducted interference. Among them, the level value of the received signal can be compared with the level value of the transmitted signal to determine whether the level value of the received signal is abnormal. If the signal level value remains in a relatively stable state, it means that the parameters of the received test signal are normal.

[0076] If it is determined that the electronic equipment is not affected by conducted interference, continue to determine whether the electronic equipment is affected by conducted interference.

[0077] S120: If it is determined that the electronic device is subject to conducted interference, then obtain received signal parameters corresponding to respective receiving ends of a plurality of sub-RF paths in the RF path of the electronic device.

[0078] Wherein, a plurality of path switches are arranged in the radio frequency path, and the plurality of path switches are used to control the formation of the plurality of sub-radio frequency paths. Figure 2As shown, when S1 is disconnected, the path from the left side of the sub-RF path S1 to the transceiver is formed, and the corresponding received signal parameters of the receiving end are the signal parameters monitored by the monitoring point on the left side of S1. When S2 is disconnected, the path from the left side of the sub-RF path S2 to the transceiver is formed. When S2 is disconnected, S1 can be controlled to be in an open state or in a closed state. The corresponding received signal parameters of the receiving end are the signal parameters monitored by the monitoring point on the left side of S2. When S3 is disconnected, the path from the left side of the sub-RF path S3 to the transceiver is formed. When S3 is disconnected, S1 and S2 can be controlled to be in an open state or in a closed state. The corresponding received signal parameters of the receiving end are the signal parameters monitored by the monitoring point on the left side of S3. When S4 is disconnected, the path from the left side of the sub-RF path S4 to the transceiver is formed. When S4 is disconnected, S1, S2 and S3 can be controlled to be in an open state or in a closed state. The corresponding received signal parameters of the receiving end are the signal parameters monitored by the monitoring point on the left side of S4. When S5 is disconnected, the sub-RF path from the left side of S5 to the transceiver is formed. When S5 is disconnected, S1, S2, S3 and S4 can be controlled to be in a disconnected state, or S1, S2, S3 and S4 can be controlled to be in a closed state. The corresponding received signal parameters of the receiving end are the signal parameters monitored by the monitoring point on the left side of S5.

[0079] Specifically, for multiple sub-RF paths in the RF path, the receiving signal parameters corresponding to each sub-RF path can be obtained in turn by controlling each path switch in turn. The target path segment to be detected can also be determined, and the corresponding receiving signal parameters of the target path segment can be detected. The target path segment can be any one or more of the sub-RF paths.

[0080] In some embodiments, a path switch in the RF path close to the antenna receiving end is used as the starting switch for disconnection processing, and the received signal parameters corresponding to the receiving end of the corresponding sub-RF path formed are obtained; multiple path switches are disconnected in order from near to far from the antenna receiving end, and each time a path switch is disconnected, the received signal parameters corresponding to the receiving end of the corresponding sub-RF path are obtained.

[0081] Specifically, combined Figure 2 As shown in the figure, after determining that the electronic device is subject to conducted interference, the control sequentially disconnects the path switches S2, S3, S4, and S5 until the received signal parameter test is normal at the point where it is disconnected, and then it is confirmed that the interference path is this section of the device routing. For example: disconnect S1, the received signal parameter test has a problem, disconnect S2 and the test still has a problem, disconnect S3 and the received signal parameter test is normal, indicating that the section from S2 to the divider and the routing is subject to conducted interference.

[0082] In some embodiments, in order to detect whether the source of conducted interference is located in a certain section, the path switch at the corresponding position can be directly disconnected for testing without disconnecting from S2 in sequence. For example, S3 can be directly disconnected to detect whether the devices and circuits on the left side of S3 are affected by conducted interference.

[0083] S130, determining a location of a conducted interference source in the RF path according to a received signal parameter corresponding to a receiving end of the sub-RF path and a transmitted signal parameter corresponding to a signal transmitting end of the RF path.

[0084] The transmission signal parameters corresponding to the signal transmitting end are parameters of the signal transmitted by the transceiver, which may be level value, frequency, amplitude, phase, noise intensity and the like.

[0085] In some embodiments, by comparing the received signal parameters corresponding to the receiving end of each sub-RF path with the transmitted signal parameters corresponding to the signal transmitting end of the RF path, the second sub-RF path corresponding to the time when the received signal parameters are in a normal state for the first time is determined; the path switch controlling the second sub-RF path is taken as the first abnormal position point, and the path switch before the path switch controlling the second sub-RF path is taken as the second abnormal position point, and it is determined that the conducted interference source is between the first abnormal position point and the second abnormal position point.

[0086] Specifically, when the first path switch is disconnected, the received signal parameters are compared with the transmitted signal parameters, if abnormal; the second path switch is disconnected, and the received signal parameters are compared with the transmitted signal parameters, if abnormal; until the second sub-RF path corresponding to the first time the received signal parameters are in a normal state is determined. Exemplarily, combined with Figure 2 As shown, disconnect S1 and test the received signal parameters to find abnormalities. When disconnecting S2, the received signal parameters are still abnormal. When disconnecting S3, the received signal parameters are tested to be normal. Then, S3 is determined to be the first abnormal position point. The path switch before S3 is S2. S2 is determined to be the second abnormal position point. The conducted interference source is located between S2 and S3.

[0087] In the above embodiment, when the signal parameter is a signal level value, by comparing the received signal parameters corresponding to the receiving end of each sub-RF path with the transmitted signal parameters corresponding to the signal transmitting end of the RF path, an implementable method for determining the second sub-RF path corresponding to the first time the received signal parameter is in a normal state includes: collecting the received signal corresponding to the receiving end of the sub-RF path, preprocessing the received signal, and parsing the preprocessed received signal into a corresponding received signal level value; by comparing the received signal level value with the transmitted signal level value corresponding to the signal transmitting end of the RF path, determining the second sub-RF path corresponding to the first time the received signal parameter is in a normal state.

[0088] In some embodiments, the signal parameter may also be a characteristic parameter. By comparing the received signal parameter corresponding to the receiving end of each sub-RF path with the transmitted signal parameter corresponding to the signal transmitting end of the RF path, a feasible method for determining the second sub-RF path corresponding to the first time the received signal parameter is in a normal state includes: collecting the received signal corresponding to the receiving end of the sub-RF path, preprocessing the received signal, parsing the preprocessed received signal into the corresponding characteristic parameter, the characteristic parameter including: at least one of frequency, amplitude, and phase; by comparing the characteristic parameter with the characteristic parameter corresponding to the signal transmitting end of the RF path, determining the second sub-RF path corresponding to the first time the characteristic parameter is in a normal state. Then determine the location of the conducted interference source in the RF path.

[0089] Among them, preprocessing includes operations such as filtering and amplification to improve the quality and analyzability of the signal. The preprocessed signal is analyzed using a preset algorithm to obtain the signal level value or characteristic parameters.

[0090] In some embodiments, in order to detect whether a conducted interference source is located in a certain section, the target section to be detected in the RF section can be first determined, as well as the first section switch at the front end of the target section and the second section switch at the rear end of the target section; the received signal parameters corresponding to the receiving end of the sub-RF section controlled by the first section switch are compared with the transmitted signal parameters corresponding to the signal transmitting end of the RF section, and the received signal parameters corresponding to the receiving end of the sub-RF section controlled by the second section switch are compared with the transmitted signal parameters corresponding to the signal transmitting end of the RF section; if the received signal parameters corresponding to the receiving end of the sub-RF section controlled by the second section switch are in an abnormal state, and the received signal parameters corresponding to the receiving end of the sub-RF section controlled by the first section switch are in a normal state, it is determined that a conducted interference source exists in the target section.

[0091] The first path switch and the second path switch are path switches for forming corresponding sub-RF paths. Figure 2 As shown, when the target path segment is determined to be a path segment between S2 and S3, S2 is the first path switch and S3 is the second path switch. Specifically, the first path switch S2 is disconnected, the corresponding received signal parameters are obtained and compared with the transmitted signal parameters, and the second path switch is disconnected, the corresponding received signal parameters are obtained and compared with the transmitted signal parameters. If the received signal parameters corresponding to the receiving end of the sub-RF path controlled by the second path switch S3 are in an abnormal state, and the received signal parameters corresponding to the receiving end of the sub-RF path controlled by the first path switch S2 are in a normal state, it is determined that there is a conducted interference source in the target path segment.

[0092] In any of the above embodiments, when the signal parameter is a level value, the received signal parameter can be obtained by scanning the receiving level and noise intensity of the entire signal path based on an NPT (Noise Profiling Tool).

[0093] Exemplarily, the receiving level and noise intensity of the entire signal path are scanned by NPT. If the noise intensity (-90dBm) is greater than the signal noise floor (-100dBm), -100dBm is the normal return value RSSI. When the return value is -90dBm, it means that there is noise interference in the current sub-RF path. If the RSSI is -90dBm when S1 is disconnected and the RSSI is -100dBm after S2 is disconnected, it means that the section between S1 and S2 is subject to noise interference.
