Detailed Description
The core of the application is to provide a noise detection method, which can perform more accurate noise detection on the electronic equipment so as to lock a noise source; another core of the present application is to provide a noise detection system, apparatus, electronic device, and computer readable storage medium, which all have the above advantages.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
The embodiment of the application provides a noise detection method.
Referring to fig. 1, fig. 1 is a flowchart of a noise detection method according to the present application, where the noise detection method may include the following steps S101 to S104.
S101: and the equipment to be tested detects the noise of the potential noise source of the auxiliary equipment to obtain detection noise information.
It should be noted that, the noise detection method provided by the present application aims to perform noise detection on the auxiliary device to be detected by the device to be detected, where, to ensure accuracy of detection results, the auxiliary device to be detected and the device to be detected may be identical devices, where, identical means that they are produced in the same batch and software and hardware are completely identical. In addition, before the auxiliary testing equipment is used for noise detection, the working states of the auxiliary testing equipment and the equipment to be tested can be set firstly, specifically, for the equipment to be tested, an antenna is taken off, a chip noise scanning function is started, only a radio frequency receiving function is started, and peripheral functions are not started; for auxiliary measurement equipment, the antenna is taken off, all peripheral functions are started, but the radio frequency receiving function is not started. It will be appreciated that overlapping conducted interference can be quickly eliminated since the device under test does not have peripheral functionality enabled.
In this step, it is intended to realize noise scanning of the device under test on the potential noise source in the auxiliary device to obtain noise information of the potential noise source (i.e., the above-mentioned detected noise information). Wherein the potential noise source, i.e. the noise source, may be a real noise source. As described above, the setting of the device to be tested includes turning on the chip noise scanning function, and therefore, based on this function, noise scanning of the potential noise source can be achieved, thereby obtaining corresponding noise information.
S102: and calling the reference noise information of the device to be tested.
The step aims at achieving acquisition of reference noise information of the device to be tested. It should be noted that, the reference noise information is the noise information of the device under test in a normal working state, where the normal working state refers to a working state that the device under test does not remove the antenna, and simultaneously starts the chip noise scanning function, the radio frequency receiving function, all peripheral functions, and all noise sources are started.
S103: and comparing and analyzing the detection noise information and the reference noise information to obtain a comparison result.
The step aims to realize the comparison analysis of noise information, namely, the comparison result of the detection noise information of the potential noise source in the auxiliary measuring equipment and the reference noise information of the equipment to be measured can be obtained by comparing and analyzing the detection noise information and the reference noise information of the equipment to be measured, and obviously, if the detection noise information and the reference noise information are matched with each other, the potential noise source is more likely to be a real noise source, and if the detection noise information and the reference noise information are not matched with each other, the potential noise source is less likely to be a real noise source.
S104: and determining a noise detection result according to the comparison result.
The step aims at determining a noise detection result of the device to be detected according to the comparison result, and obviously, the comparison result is used for judging whether a potential noise source in the auxiliary measuring device is a real noise source or not. It can be understood that, since the auxiliary measuring device and the device to be measured are identical devices, after determining whether the potential noise source in the auxiliary measuring device is a real noise source, it can be determined whether the potential noise source in the same position in the device to be measured is a real noise source, thereby realizing noise detection of the device to be measured.
It should be noted that, the number of potential noise sources that may exist in the auxiliary measurement device is not unique, and for the case that a plurality of potential noise sources exist in the auxiliary measurement device, steps S101 to S104 may be adopted to detect each potential noise source in sequence, so as to lock all real noise sources that exist in the auxiliary measurement device, and further lock all real noise sources that exist in the device to be measured.
Therefore, in the noise detection method provided by the embodiment of the application, the noise detection of the auxiliary detection equipment is realized through the equipment to be detected, in the realization process, the potential noise source of the auxiliary detection equipment is firstly determined, then the equipment to be detected scans the noise of the potential noise source to obtain the detection noise information of the noise source, and then the detection noise information is compared and analyzed with the reference noise information of the equipment to be detected, so that the noise detection result is determined according to the comparison result, namely whether the potential noise source in the auxiliary detection equipment is a real noise source is determined according to the comparison result, and then the noise source in the auxiliary detection equipment is locked.
Based on the above embodiments:
in an embodiment of the present application, the performing noise detection on the potential noise source of the auxiliary measurement device to obtain detection noise information may include:
the method comprises the steps of performing noise detection on a potential noise source of auxiliary measuring equipment by using radio frequency detecting equipment and a low-noise amplifier to obtain detection noise information;
the radio frequency detection equipment is connected with the low-noise amplifier, the low-noise amplifier is connected with an antenna connector of the equipment to be detected, and the radio frequency detection equipment is used for carrying out noise scanning close to a potential noise source.
The embodiment of the application provides a realization method for detecting the noise of a potential noise source in auxiliary measuring equipment to acquire detection noise information, namely, a radio frequency probe and a low-noise amplifier can be utilized to perform noise scanning on the potential noise source of the auxiliary measuring equipment to acquire corresponding detection noise information. The radio frequency probe is used for scanning noise close to a potential noise source, and the position and the direction can be dynamically adjusted in the scanning process so as to ensure that the noise is detected; the low noise amplifier is connected to an antenna connector of the auxiliary measuring device, and has a function of amplifying noise. It follows that the combination of the radio frequency probe and the low noise amplifier helps to achieve rapid, flexible and accurate capture of noise.
In one embodiment of the application, the detected noise information is specifically a detected noise curve, and the reference noise information is specifically a reference noise curve;
the comparing and analyzing the detection noise information and the reference noise information to obtain a comparison result may include:
performing form fitting on the detection noise curve and the reference noise curve to obtain curve fitting degree;
and taking the curve fitting degree as a comparison result.
The embodiment of the application provides a method for realizing comparison and analysis of detection noise information and reference noise information. In the implementation process, the detection noise information can be specifically a detection noise curve of a potential noise source in the auxiliary detection equipment, the reference noise information can be specifically a reference noise curve of the equipment to be detected, then, the comparison analysis of the detection noise information and the reference noise information can be specifically curve fitting of the detection noise curve and the reference noise curve, and correspondingly, the comparison result is the curve fitting degree of the detection noise curve and the reference noise curve. It can be appreciated that the higher the value of the curve fitting degree, the more the two are matched, and the greater the possibility that the potential noise source is a true noise source; conversely, if the lower the value of the curve fitting degree is, the less the two are matched, the less the potential noise source is a true noise source.
In an embodiment of the present application, the determining a noise detection result according to the comparison result may include:
when the curve fitting degree exceeds a preset threshold, determining that the potential noise source is a real noise source;
and when the curve fitting degree does not exceed a preset threshold value, determining that the potential noise source is not a real noise source.
The embodiment of the application provides a method for determining a noise detection result according to curve fitting degree. As described above, the higher the value of the curve fitting degree, the greater the likelihood that the potential noise source is a real noise source; the lower the value of the curve fitting degree, the less likely the potential noise source is a real noise source, and therefore, whether the potential noise source is a real noise source can be determined by performing threshold evaluation on the curve fitting degree. Specifically, when the curve fitting degree exceeds a preset threshold, the potential noise source can be determined to be a real noise source, and when the curve fitting degree does not exceed the preset threshold, the potential noise source can be determined to be not the real noise source. It should be noted that, the specific value of the preset threshold does not affect the implementation of the technical scheme, and the technical scheme is set by a technician according to the actual requirement, which is not limited by the application.
In one embodiment of the present application, the noise detection method may further include:
the detected noise curve and the reference noise curve are sent to a spectrum analyzer to show curve fitting results with the spectrum analyzer.
The noise detection method provided by the embodiment of the application can further realize the display function. Specifically, after the detection noise curve of the potential noise source of the auxiliary testing device and the reference noise curve of the device to be tested are obtained, the detection noise curve and the reference noise curve of the auxiliary testing device can be sent to a spectrum analyzer together, so that the noise spectrum, the morphological fitting process, the curve fitting result and the like of the auxiliary testing device and the reference noise curve can be displayed in real time based on the spectrum analyzer.
In the above embodiment, an implementation manner of performing noise scanning on a potential noise source based on a radio frequency probe and a low noise amplifier is provided, on the basis, a power divider can be additionally arranged between the low noise amplifier and an antenna connector of auxiliary measurement equipment, and the power divider is also connected with a spectrum analyzer, so that scanning results fed back by the radio frequency probe and the low noise amplifier can be fed back to equipment to be measured through the power divider for subsequent processing, and the scanning results can be sent to the spectrum analyzer for visual display.
In one embodiment of the present application, the noise detection method may further include:
under the condition that a real noise source is closed and other noise sources are opened, a single machine detection noise curve of the equipment to be detected is obtained;
when the curve amplitude of the single machine detection noise curve is lower than that of the reference noise curve, the real noise source is determined to be an effective noise source.
The noise detection method provided by the embodiment of the application can further verify whether the detected real noise source is an effective noise source, namely judging whether the real noise source can actually generate noise interference. Specifically, after determining that the potential noise source in the auxiliary measurement device is a real noise source, that is, after determining that the target noise source in the device to be measured, which is at the same position as the potential noise source, is a real noise source, a single-machine detection noise curve of the device to be measured can be further obtained, and it is to be noted that the single-machine detection noise curve is obtained by performing single-machine detection on the real noise source of the device to be measured under the condition that the real noise source of the device to be measured is turned off and other noise sources are turned on; further, comparing the curve amplitude of the single-machine detection noise curve with the curve amplitude of the reference noise curve of the equipment to be detected, if the curve amplitude of the single-machine detection noise curve is lower than the curve amplitude of the reference noise curve, determining that the real noise source is an effective noise source, wherein the real noise source refers to the potential noise source in the auxiliary equipment and also refers to a target noise source (with the potential noise source) at the same position in the equipment to be detected; otherwise, if the curve amplitude of the single-machine detection noise curve is not lower than the curve amplitude of the reference noise curve, the real noise source can be determined to be not an effective noise source, and the verification of the next detected real noise source can be continued.
In one embodiment of the present application, the noise detection method may further include:
acquiring a reverse detection result of auxiliary equipment to be detected;
verifying the noise detection result by using the inverse detection result to obtain a verification result;
the process of obtaining the inverse detection result may include:
the auxiliary testing equipment detects noise of a target noise source of the equipment to be tested to obtain anti-detection noise information; the position of the target noise source in the equipment to be detected is the same as the position of the potential noise source in the auxiliary equipment to be detected;
and determining an inverse detection result according to the comparison result of the inverse detection noise information and the reference noise information of the auxiliary detection equipment.
The noise detection method provided by the embodiment of the application can further realize the verification function of the noise detection result so as to effectively ensure the accuracy of the noise detection result. Specifically, after the noise detection of the auxiliary measurement equipment is completed based on the equipment to be measured, the auxiliary measurement equipment and the equipment to be measured are completely the same electronic equipment, so that the auxiliary measurement equipment can be utilized to reversely detect the equipment to be measured once to obtain a corresponding reverse detection result, and therefore, the actual noise detection result can be verified by utilizing the reverse detection result to obtain a final verification result, and obviously, the verification result is used for indicating whether the noise detection result of the auxiliary measurement equipment is accurate or not.
The method comprises the steps that the inverse detection process of auxiliary equipment to be detected is basically consistent with the noise detection process of the auxiliary equipment to be detected, specifically, the working states of the auxiliary equipment to be detected and the auxiliary equipment to be detected can be set in a reversed mode by referring to the preparation work (the setting of the working states of the auxiliary equipment to be detected) when the auxiliary equipment to be detected detects noise, on the basis, the auxiliary equipment to be detected scans the noise of a target noise source of the equipment to be detected to obtain inverse detection noise information of the target noise source, and the position of the target noise source in the equipment to be detected is identical with the position of a potential noise source in the auxiliary equipment to be detected, in other words, the target noise source is the potential noise source corresponding to the potential noise source in the auxiliary equipment to be detected; further, the reference noise information (which is basically consistent with the reference noise information of the device to be tested) of the auxiliary test device is called, and is compared and analyzed with the anti-detection noise information to obtain a comparison result, so that the anti-detection result of the auxiliary test device to the device to be tested can be determined according to the comparison result, namely whether the target noise source is a real noise source of the device to be tested is determined.
In an embodiment of the present application, the verifying the noise detection result using the inverse detection result to obtain a verification result may include:
when the inverse detection result is consistent with the noise detection result, determining that the verification result is verification passing;
and when the anti-detection result is inconsistent with the noise detection result, determining that the verification result is verification failure.
The embodiment of the application provides a realization method for verifying a noise detection result by utilizing an inverse detection result. It can be understood that the noise detection result is whether the potential noise source in the auxiliary measuring device is a real noise source or not, the inverse detection result is whether the target noise source in the device to be measured is a real noise source or not, and because the potential noise source and the target noise source are positioned at the same position of the electronic device, if the inverse detection result is consistent with the noise detection result, the verification is passed, and the noise detection result is determined to be real and effective; if the anti-detection result is inconsistent with the noise detection result, the verification is not passed, the noise detection result is determined to be inaccurate, and at the moment, a retest prompt can be further output.
On the basis of the above embodiments, another noise detection method is provided in the embodiments of the present application.
Referring to fig. 2, fig. 2 is a schematic structural diagram of a noise detection system provided by the present application, in which an electronic device 1 is an auxiliary measurement device, an electronic device 2 is a device to be measured, both are the same products of the same batch of hardware and software, 103, 104, 105 shown in fig. 2 are all potential noise sources in the electronic device 1, 203, 204, 205 are all potential noise sources in the electronic device 2, 101 and 201 are respectively antenna connectors of the two, 106 and 206 are respectively a radio frequency probe and a low noise amplifier of the two, 107 is a power divider, and 108 is a spectrum analyzer.
Further, referring to fig. 3, fig. 3 is a schematic flow chart of noise detection on an auxiliary device by a device under test according to the present application. In connection with the noise detection flow illustrated by the solid line shown in fig. 2, first, in a normal operation state of the electronic apparatus 1 and the electronic apparatus 2, an initial noise curve (reference noise curve) L0 of both is measured. Then, the following settings were made for both: taking off the antennas of 2 electronic devices, wherein the electronic device 2 starts a chip noise scanning function, starts a radio frequency receiving function and does not start a peripheral function, and a radio frequency probe and a low noise amplifier are connected to an antenna connector 201 of the electronic device 2 through a coaxial line; the electronic device 1 turns on all peripheral functions but not the radio frequency receiving function, while bringing the radio frequency probe directly close to the potential noise source of the electronic device 1, e.g. 103, i.e. the noise source 103 of the electronic device 1 is scanned by the electronic device 2 at this time. At this time, since the electronic device 2 does not turn on the peripheral function, overlapping conduction interference can be rapidly eliminated, and the radio frequency probe and the low noise amplifier 106 can dynamically move to adjust the position and direction against the noise source of the electronic device 1, and can amplify noise, thereby capturing noise rapidly and flexibly. Further, through the power distributor 107, one path is sent to the spectrum analyzer 108 for visual display, and the other path is directly scanned by the chip of the electronic device 2 to obtain the latest amplified noise curve L2. Finally, the noise curves L0 and L2 are subjected to morphological difference fitting judgment, and if the two curves are highly fitted, it is determined that 103 is indeed one of the noise sources, at this time, the curve L2 and the detection noise source 103 can be recorded, and the noise spectrum in the recording spectrum analyzer can be saved (the spectrum can compensate the gain of the low noise amplifier). To this end, the detection of the noise source 103 in the electronic device 1 is completed, and further, the above-described flow may be used to sequentially detect the potential noise sources 104 and 105 in the electronic device 1.
Further, referring to fig. 4, fig. 4 is a schematic flow chart of reverse detection of a device to be detected by an auxiliary device according to the present application. Combining the noise detection flow shown by the dotted line in fig. 2, exchanging the electronic device 2 with the electronic device 1, and repeating the above steps, so as to realize detection of potential noise sources 203, 204, 205 in the electronic device 2 by the electronic device 1.
Therefore, the detection result of the operation flow shown in fig. 3 is compared with the detection result of the operation flow shown in fig. 4, and if the detection result is consistent with the detection result of the operation flow shown in fig. 4, a real noise source in the electronic equipment can be locked.
Finally, for each real noise source locked in the electronic device 2, the real noise source may be turned off first, and other noise sources may be turned on to obtain a single-machine detected noise curve of the electronic device 2, so as to compare the curve amplitude of the single-machine detected noise curve with the curve amplitude of the reference noise curve of the electronic device 2, and if the curve amplitude of the single-machine detected noise curve is reduced compared with the curve amplitude of the reference noise curve, it may be determined that the real noise source is indeed an effective noise source. On the basis, all real noise sources in the electronic device 2 are sequentially verified based on the mode, so that all effective noise sources in the electronic device 2 are locked.
Therefore, in the noise detection method provided by the embodiment of the application, the noise detection of the auxiliary detection equipment is realized through the equipment to be detected, in the realization process, the potential noise source of the auxiliary detection equipment is firstly determined, then the equipment to be detected scans the noise of the potential noise source to obtain the detection noise information of the noise source, and then the detection noise information is compared and analyzed with the reference noise information of the equipment to be detected, so that the noise detection result is determined according to the comparison result, namely whether the potential noise source in the auxiliary detection equipment is a real noise source is determined according to the comparison result, and then the noise source in the auxiliary detection equipment is locked.
The embodiment of the application provides a noise detection device.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a noise detection device provided by the present application, where the noise detection device may include:

and the determining module 4 is used for determining a noise detection result according to the comparison result.
Therefore, the noise detection device provided by the embodiment of the application realizes the noise detection of the auxiliary detection equipment through the equipment to be detected, in the implementation process, firstly, the potential noise source of the auxiliary detection equipment is determined, then the equipment to be detected scans the noise of the potential noise source to obtain the detection noise information of the noise source, and further, the detection noise information is compared and analyzed with the reference noise information of the equipment to be detected, so that the noise detection result is determined according to the comparison result, namely, whether the potential noise source in the auxiliary detection equipment is a real noise source is determined according to the comparison result, and then the noise source in the auxiliary detection equipment is locked.
