All other embodiments, which can be obtained by a person skilled in the art without inventive work based on the embodiments of the present invention, are within the scope of the present invention.
In order to make the objects, technical solutions and advantageous technical effects of the present invention more clearly and completely apparent, the technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It will be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The invention provides a signal interference debugging method, which is used for debugging the interference of an electronic device on a wireless signal. Referring to fig. 1, a schematic diagram of a frame structure of the signal comprehensive tester 400 and the computer 300 for performing the radiation test on the circuit board 150 is disclosed. The signal comprehensive tester 400 is connected with the computer 300, specifically connected through a network cable, so as to realize network intercommunication; the signal comprehensive tester 400 is connected with the circuit board 150, specifically connected through the radio frequency connector 401, and simulates a signal transmission path; the circuit board 150 is connected to the computer 300, specifically connected by a USB connection line, to realize data and power connection, and the circuit board 150 is disposed in the shielding frame 403. By the above connection, the conduction power of the circuit board 150 and the first reception sensitivity RX1 can be measured by a predetermined measurement method. In the embodiment, the description is given by taking the Wi-Fi signal as an example, specifically an 802.11g-54Mbps-channel7 signal.
Specifically, the computer 300 controls the circuit board 150 to operate, and performs a radiation action, i.e., sending a signal, the signal is conducted to the signal comprehensive tester 400 through the rf connector 401, and the signal comprehensive tester 400 reads the conduction power of the signal, i.e., the detection of the conduction power of the circuit board 150 is completed.
On the other hand, the computer 300 controls the signal comprehensive tester 400 to send signals with different powers, the signals are conducted to the circuit board 150 through the radio frequency connector 401, the computer 300 reads the lowest power value in the signals that can be received by the circuit board 150, namely the first receiving sensitivity RX1 of the circuit board 150, and the sensitivity detection is completed. For example, when the signal synthesizer 400 sends out a signal of-11 dBm, the circuit board 150 cannot receive the signal, and when the signal synthesizer 400 sends out a signal of-10 dBm, the circuit board 150 normally receives the signal, that is, the first receiving sensitivity RX1 of the circuit board 150 is detected to be-10 dBm.
Referring to fig. 2, a frame structure diagram of the signal comprehensive tester 400 and the computer 300 for radiation testing of the electronic device 200 is disclosed, similar to the testing method in fig. 1. The circuit board 150 is mounted on the electronic device 200, the electronic device 200 includes a radio frequency antenna 201 connected to the circuit board 150, and the radio frequency antenna 201 is used for transmitting wireless signals; the signal comprehensive tester 400 is connected with the computer 300, specifically connected through a network cable, so as to realize network intercommunication; the signal comprehensive tester 400 is connected with a receiving antenna 402 through a radio frequency connector 401, and the receiving antenna 402 and the radio frequency antenna 201 work correspondingly to simulate a wireless signal transmission path; the circuit board 150 is connected to the computer 300, specifically connected via a USB cable, to implement data and power connection, and the electronic device 200 is disposed in the shielding frame 403. Through the above connection method, the antenna signal attenuation value a and the second receiving sensitivity RX2 of the electronic device 200 can be measured by a predetermined measurement method.
Specifically, the computer 300 controls the circuit board 150 to operate, and performs a radiation action, i.e. sending a signal, and the signal sends out a wireless signal through the rf antenna 201, where the power of the wireless signal is specifically the conducted power detected by the apparatus in fig. 1. The receiving antenna 402 receives a wireless signal sent by the rf antenna 201, and transmits the wireless signal to the signal comprehensive tester 400 through the rf connector 401, and the signal comprehensive tester 400 reads a measurement power, and the difference between the measurement power and the conduction power is the antenna signal attenuation value a. Specifically, for example, the rf antenna 201 emits a radio signal of 12dBm, and the signal comprehensive tester 400 reads a signal with a power of 10dBm, i.e., the antenna signal attenuation value a is 2 dBm.
On the other hand, the computer 300 controls the signal comprehensive tester 400 to send signals with different powers, the signals are sent through the rf connector 401 and the receiving antenna 402, the rf antenna 201 receives the wireless signals and then conducts the wireless signals to the circuit board 150, and the computer 300 reads the lowest power value in the signals that can be received by the circuit board 150, that is, the lowest power value is the second receiving sensitivity RX2 of the electronic device 200. For example, when the signal synthesizer 400 sends out a signal of-10 dBm, the circuit board 150 cannot receive the signal, and when the signal synthesizer 400 sends out a signal of-9 dBm, the circuit board 150 normally receives the signal, i.e., detects that the second receiving sensitivity RX2 of the circuit board 150 is-9 dBm. It can be understood that, when the radio frequency antenna 201 emits a radio signal or receives a radio signal, the radio signal has the same path directly passed by the radio frequency antenna 201 and the receiving antenna 402, and therefore the signal attenuation thereof is the same, so that when the second receiving sensitivity RX2 of the electronic device 200 is detected to be-9 dBm, the true receiving sensitivity RXT of the electronic device 200 is RX2-a, and when the antenna signal attenuation value a is 2dBm according to the foregoing strategy, the true receiving sensitivity RXT is-11 dBm. Further, the first reception sensitivity RX1 of the circuit board 150 detected by the apparatus according to FIG. 1 is-10 dBm, while the true reception sensitivity RXT of the circuit board 150 detected after mounting to the electronic device 200 is-11 dBm, for example. It is understood that, in an ideal situation, the first receiving sensitivity RX1 of the circuit board 150 should be close to the true receiving sensitivity RXT of the electronic device 200, but the true receiving sensitivity RXT of the electronic device 200 is lower than the first receiving sensitivity RX1 due to interference of other electronic devices in the electronic device 200 to wireless signals, for example, in the above case, the first receiving sensitivity RX1 of the circuit board 150 is-10 dBm, the true receiving sensitivity RXT of the electronic device 200 is-11 dBm, and the difference between the two is 1dBm, that is, caused by interference generated by other electronic devices. It is understood that when the interference caused by the electronic device to the receiving sensitivity is reduced to a proper value, for example, 0.2dBm, in this case, the detection of the second receiving sensitivity RX2 of the electronic device 200 by the above-mentioned equipment should be-8.2 dBm, and the true receiving sensitivity RXT of the electronic device 200 is calculated to be-10.2 dBm, at this time, the interference of the electronic device is low, and it can be considered that it is in an acceptable interference range, and the signal of the electronic device 200 is normal.
Preferably, the electronic device 200 includes a charging device, a routing device, and the like, in this embodiment, the electronic device 200 is a charging device, the charging device charges an electric vehicle, and a Wi-Fi or bluetooth communication unit is built in, and can be connected to a user mobile terminal or an electric vehicle Wi-Fi or bluetooth to implement wireless communication.
Referring to fig. 3, a flow chart of the signal interference debugging method is schematically illustrated, and the method includes:
step S10 of acquiring a first reception sensitivity RX1 of the circuit board 150 in the electronic apparatus 200, and step S20 of acquiring an antenna signal attenuation value a of the electronic apparatus 200 and a second reception sensitivity RX2 of the electronic apparatus 200, and calculating a true reception sensitivity RXT — RX 2-a;
step S30, if it is determined that the first difference B between the first receiving sensitivity RX1 and the real receiving sensitivity RXT is not less than the first preset value, a first debugging instruction is generated and sent according to a first preset rule, the first debugging instruction controls parameters of electronic devices in the electronic device to be debugged, and after debugging, the antenna signal attenuation value a ' and the second receiving sensitivity RX2 ' are obtained again, and a new real receiving sensitivity RXT ' is calculated as RX2 ' -a '; and the number of the first and second groups,
step S40, determining that the first difference B ' between the new first receiving sensitivity RX1 ' and the new true receiving sensitivity RXT ' is smaller than the first preset value, and outputting debug completion information.
In this embodiment, the signal interference debugging method is based on a signal radiation test performed by the signal comprehensive tester 400 and the computer 300 on the circuit board 150 or the electronic device 200. The first receiving sensitivity RX1 of the circuit board 150 is actually obtained by performing a signal radiation test on the circuit board 150 according to the apparatus shown in fig. 1, and will not be described herein again, the detected first receiving sensitivity RX1 is stored in the computer 300, and in the step S10, the computer retrieves the stored first receiving sensitivity RX 1.
In the step S20, the antenna signal attenuation value a and the second receiving sensitivity of the electronic apparatus 200 are actually obtained by performing a signal radiation test on the electronic apparatus 200 according to the apparatus shown in fig. 2, which is not repeated herein, and the computer 300 reads the detected antenna signal attenuation value a and the second receiving sensitivity RX2, and correspondingly calculates the actual receiving sensitivity RXT of the electronic apparatus 200.
It is understood that, in the present embodiment, the steps S10 and S20 of performing the signal test on the circuit board and the step S of performing the signal test on the electronic device are independent, and the order of the two steps is not limited, and the first receiving sensitivity of the circuit board may be obtained by first detecting the circuit board and then detecting the electronic device to obtain the antenna signal attenuation value and the second receiving sensitivity of the electronic device, or conversely, the first receiving sensitivity may be obtained by first detecting the electronic device and then detecting the circuit board.
In the step S30, the first receiving sensitivity RX1 obtained in the step S10 and the real receiving sensitivity RXT obtained in the step S20 are compared, a first difference B between the two is compared with a first preset value, and when the first difference B is not less than the first preset value, it indicates that the real sensitivity RXT of the electronic apparatus is higher, the signal is influenced by the interference of the electronic device in the electronic apparatus 200, in which case it is necessary to debug the electronic interference condition of the electronic device, therefore, the computer 300 generates a first debug command for performing debug control on the electronic device according to a first preset rule, the debug command is sent to the electronic apparatus 200 through the computer 300, controls the parameter adjustment of the electronic device, after the debug, the above step S20 is executed again to obtain a new antenna signal attenuation value a 'and a new second receiving sensitivity RX 2', and calculating a new real receiving sensitivity RXT ', and comparing the first receiving sensitivity RX1 with the new real receiving sensitivity RXT' again until it is determined that a new first difference B 'between the new first receiving sensitivity RX 1' and the new real receiving sensitivity RXT 'is smaller than the first preset value, at this time, the first difference B' is smaller than the first preset value, which indicates that the interference value of the electronic device in the electronic device 200 to the signal is reduced to a lower value, and in an acceptable range, outputting debugging completion information. According to different actual application devices and signal types, the influence degree of interference of electronic devices on device signals is also different, in this embodiment, for example, the Wi-Fi signal 802.11g-54Mbps-channel7 is taken as an example, the first preset value may be set to 0.5dBm, and it can be understood that, in other embodiments, the first preset value may also be set to different other values, for example, 0.3dBm, 0.8dBm, 1mdB, and the like.
In this embodiment, the computer 300 and the signal comprehensive tester 400 are used to perform signal testing on the circuit board 150 or the electronic device 200, and it is understood that in other embodiments, the computer and the signal comprehensive tester may be configured as an integrated device, such as a computer device with a signal testing function, or a computer dedicated for signal testing, which mainly includes a testing portion connected to the circuit board 150 or the electronic device 200 through signals and a control portion connected to the circuit board 150 or the electronic device 200 in data communication, where the testing portion is similar to the signal comprehensive tester 400, and the control portion is similar to the computer 300, and will not be described again.
Further, in another embodiment, in the step S30, if it is determined that the first difference B between the first receiving sensitivity RX1 and the real receiving sensitivity RXT is not less than the first preset value, a first debugging command is generated and sent according to a first preset rule, the first debugging command controls parameters of an electronic device in the electronic device to be debugged, the antenna signal attenuation value a ' and the second receiving sensitivity RX2 ' are obtained again after the debugging, and after the new real receiving sensitivity RXT ' is calculated as RX2 ' -a ', the method further includes:
step S50, if it is determined that the new first difference B' is not less than the first preset value, re-generating and sending the first debugging command according to the first preset rule, and re-executing the above-mentioned obtaining, determining, or debugging actions after debugging until the re-determined first difference B ″ is less than the first preset value.
In this embodiment, on the basis of the foregoing embodiment, after the antenna signal attenuation value a 'and the second receiving sensitivity RX 2' are re-acquired and the new real receiving sensitivity RXT 'is calculated, the new real receiving sensitivity RXT' is compared with the first receiving sensitivity RX1, the first difference B 'between the new real receiving sensitivity RXT' and the first receiving sensitivity RX1 is compared with the first preset value, if the difference is still not less than the first preset value, the first debugging instruction is re-generated and debugged, and the data acquisition and determination operations are re-executed after debugging until the first difference after debugging is less than the first preset value, so as to complete the debugging. In this embodiment, the detection and debugging process is set to the circulation mode, so that the device can automatically and efficiently debug signal interference in the electronic device, and manual debugging is avoided.
Further, in the step S30, if it is determined that the first difference B between the first receiving sensitivity RX1 and the real receiving sensitivity RXT is not less than the first preset value, a first debugging command is generated and sent according to a first preset rule, the first debugging command controls parameters of an electronic device in the electronic device to be debugged, the antenna signal attenuation value a ' and the second receiving sensitivity RX2 ' are obtained again after debugging, and the calculating of the new real receiving sensitivity RXT ' ═ RX2 ' -a ' specifically includes:
determining that a first difference value B between the first receiving sensitivity RX1 and the real receiving sensitivity RXT is not less than the first preset value, determining an electronic device to be debugged according to a second preset rule, generating and sending a first debugging instruction or generating debugging prompt information, wherein the first debugging instruction controls an output parameter for debugging the electronic device to be debugged, the debugging prompt information is used for indicating a state of the electronic device to be debugged, and after debugging, re-acquiring the antenna signal attenuation value a ' and the second receiving sensitivity RX2 ', and calculating the real receiving sensitivity RXT ' ═ RX2 ' -a '.
In this example, on the basis of the foregoing embodiment, the first difference B is compared with a first preset value, whether the difference between the true receiving sensitivity RXT and the first receiving sensitivity RX1 is within an acceptable range is determined, if the difference is determined to be in the acceptable range, the electronic device in the electronic apparatus needs to be debugged, at this time, the electronic device to be debugged is determined according to a second preset rule, and a first debugging instruction is generated, where the first debugging instruction is used to control and debug an output parameter of the electronic device to be debugged, the electronic apparatus is re-detected after debugging to obtain a relevant parameter, the foregoing comparison step is performed again, and the foregoing debugging step is performed in a loop. It can be understood that, in another embodiment, the debugging apparatus or the computer may be configured to generate, instead of generating the first debugging instruction, a debugging prompt message to indicate a state of the electronic device to be debugged, where the debugging prompt message is directly displayed by the apparatus or the computer and sent to the user mobile terminal or the management platform, and when the detection personnel receives the debugging prompt message, the electronic device may be correspondingly shielded and debugged according to the debugging prompt message, and the specific shielding and debugging means includes setting a shielding case or a magnetic ring for the electronic device, so that a radiation signal of the electronic device is shielded, and interference to a wireless signal of the electronic device is reduced, and after the corresponding debugging is performed, the test data is reacquired, so as to improve accuracy of the debugging.
Further, in another embodiment, the determining the electronic device to be debugged according to the second preset rule specifically includes:
acquiring a main frequency F of an electronic device, calculating reference main frequencies F1, F2, … and Fn of the electronic device according to the main frequency F, wherein F1 is F, F2 is 2F, … is F, and Fn is nf, acquiring a communication frequency band of a wireless signal, and determining the electronic device to be debugged, wherein the reference main frequencies F1, F2, … and Fn of the electronic device to be debugged are in the communication frequency band.
Based on the foregoing embodiment, by matching the main frequency f and the corresponding frequency multiplication of the electronic device with the frequency of the wireless signal, it can be understood that when the main frequency f or the corresponding frequency multiplication of the electronic device falls into the frequency band of the wireless signal, the signal with the corresponding frequency is a source of interference to the wireless signal in the electronic apparatus 200, and the parameters of the electronic devices are debugged, that is, the interference to the wireless signal can be correspondingly changed until the interference value is debugged to be reduced to an acceptable range, so that the corresponding debugging is completed.
Further, n is one of 5, 6, 7, 8, 9 or 10.
In this embodiment, signals of other electronic devices are periodic signals, and according to the principle of discrete digital signals, the representation of the periodic square wave signals in the frequency domain can be obtained through fourier transform, where the conversion formula is:
the harmonic frequency is 2 pi k/N, the amplitude value is X to (k)/N, when the value of N is larger, the amplitude value is correspondingly reduced, and it can be understood that when the amplitude value is reduced to be smaller, the interference intensity of the signal of the electronic device on the wireless signal is also very low, the electronic device is debugged immediately, and the change of the interference value is also very low and can be ignored. By the method, the electronic devices generating interference are accurately screened, waste of testing and debugging resources is avoided, and debugging efficiency is improved.
Further, in another embodiment, the first debug instruction specifically includes: a close electronics command; alternatively, the electronic device driving strength is reduced; alternatively, the electronics frequency change command.
In this embodiment, the actual debugging of the electronic device includes various steps, such as turning off the electronic device, reducing the driving strength, or adjusting the operating frequency, and by operating one of these modes, the interference actually generated by the electronic device changes, and is reflected in the subsequent re-detection.
Further, in the step S10, before acquiring the first receiving sensitivity RX1 of the circuit board 150, the method further includes;
in step S60, the first reception sensitivity RX1 of the circuit board is stored.
In this embodiment, before the first receiving sensitivity RX1 of the circuit board 150 is obtained, the circuit board 150 is tested according to the connection and test of the device shown in fig. 1 to obtain the corresponding first receiving sensitivity RX1, and the first receiving sensitivity RX1 is further stored and recorded, and then is used for calling in a subsequent debugging step.
Further, referring to fig. 4, in another embodiment, in the step S60, the storing the first receiving sensitivity RX1 of the circuit board specifically includes:
step S61, receiving a first reception sensitivity RX1 of the circuit board;
step S62, if it is determined that the second difference C between the first reception sensitivity RX1 and the reference reception sensitivity is smaller than the second preset value, storing the first reception sensitivity RX 1; or the like, or, alternatively,
step S63, if it is determined that the second difference C between the first receiving sensitivity RX1 and the reference receiving sensitivity is not less than the second preset value, generating first conductive debugging prompting information, where the first conductive debugging prompting information is used to indicate a state of the circuit board to be debugged, re-executing the acquiring and determining actions for the first receiving sensitivity RX1 after debugging until it is determined that the new second difference C ' between the new first receiving sensitivity RX1 ' and the reference receiving sensitivity is less than the second preset value, and storing the first receiving sensitivity RX1 '.
In this embodiment, when the first receiving sensitivity RX1 of the circuit board 150 is tested according to fig. 1, the tested first receiving sensitivity RX1 is further specifically verified, and the measured first receiving sensitivity RX1 is compared with a reference receiving sensitivity, specifically, the reference receiving sensitivity is a standard parameter determined before the circuit board 150 is shipped from a factory or reference data obtained by statistics according to a large number of actual uses. In this way, the accuracy of the detected first reception sensitivity RX1 can be determined. In the verification process, if the first receiving sensitivity RX1 data is determined to be abnormal, then conduction debugging prompt information is generated, the equipment connection needs to be debugged, the detection is continued after the equipment or the line is debugged, and whether the data is normal or not is redetected and judged. Specifically, the conducted debugging is actually debugging a physical connection channel, which includes IC internal baseband signal debugging, mixer debugging, IC output port matching debugging, PA/LNA matching debugging, and corresponding data tuning from an original digital signal to a coded digital signal, a modulated radio frequency signal, and a radio frequency signal.
Specifically, in step S61, the testing device or the computer 300 receives the first receiving sensitivity detected by the signal comprehensive tester 400, and if not in step S62, verifies the received first receiving sensitivity, and compares the received first receiving sensitivity with a reference receiving sensitivity, where the reference receiving sensitivity may be a receiving sensitivity value with the highest occurrence frequency according to a parameter provided by a manufacturer when the circuit board leaves the factory or statistically obtained from big data in an actual application context of the in-industry device, and when a second difference C between the first receiving sensitivity and the reference receiving sensitivity is determined to be smaller, specifically smaller than a second preset value, the first receiving sensitivity is stored, and verification and storage of the receiving sensitivity are completed. On the contrary, when the second difference C is not smaller than the second preset value, first conduction debugging information is generated to indicate that the first receiving sensitivity value is not in the normal range and needs to be debugged in the detection of the receiving sensitivity of the circuit board, and the first conduction prompting information indicates the state of the circuit board to be debugged, and the verification step is performed after the debugging until the second difference C between the first receiving sensitivity RX 1' and the reference receiving sensitivity is smaller than the second preset value, that is, the first receiving sensitivity is in the acceptable range. It is understood that the second preset value may be set to different values, for example, 0.1dBm, 0.05dBm, 0.15mdB, etc., according to different devices or application scenarios.
