Summary of the application
As described above, in order to solve the problem of electromagnetic interference in automatic driving, usually, interference hardware such as hardware filtering and hardware shielding is used for protection, but as the interference hardware is used for a long time, a potential failure problem exists, and a problem that the pure hardware protection is not easy to find once the hardware protection fails exists, so how to effectively reduce the probability of failure of electromagnetic interference protection, and ensure the stability of electromagnetic interference protection.
Based on the technical problem, the basic concept of the present application is to mix a first signal corresponding to a first operating frequency of a hardware module with a second signal corresponding to a second operating frequency to obtain a third signal; and when the first amplitude corresponding to the third signal is detected to meet the preset condition, the first working frequency is adjusted to be a third working frequency, and the amplitude corresponding to the third working frequency can be controlled not to meet the preset condition.

Having described the general principles of the present application, various non-limiting embodiments of the present application will now be described with reference to the accompanying drawings.
Exemplary method
Fig. 1 is a method for adjusting a frequency of a hardware module according to an exemplary embodiment of the present application. The embodiment can be applied to an electronic device, as shown in fig. 1, and includes the following steps:
The hardware module comprises hardware such as a positioning chip, a horizontal sensor, an angular velocity sensor, an acceleration sensor, a central processing unit, a mobile communication chip and a vehicle body control chip. And the first working frequency is an actual working frequency point of the hardware module. The second working frequency is an ideal working frequency point of the hardware module, and the SOC central processing unit stores the frequency information in a truth table form into the RAM.
Specifically, after the amplitude of the third signal is obtained, it is detected whether the amplitude of the third signal meets the preset condition, and if the amplitude of the third signal meets the preset condition, it is proved that the hardware module is subjected to electromagnetic interference, so step 103 is executed to adjust the first operating frequency to the third operating frequency, and store the third operating frequency in the RAM. And the third working frequency is within the working frequency range of the hardware module, and is used for determining that the hardware module after the frequency adjustment can work normally. If not, the hardware module is proved not to be subjected to electromagnetic interference, and the first working frequency is not adjusted.
In an embodiment, a fourth operating frequency corresponding to the third operating frequency stored in the RAM needs to be obtained, where the fourth operating frequency is an ideal operating frequency of the hardware module after the frequency adjustment. The above step 101-103 is repeated until the preset condition is not met, and the frequency does not need to be adjusted.
Because the preset condition is related to the amplitude, the amplitude corresponding to the actual working frequency of the hardware module can be checked through the preset condition, and then whether the hardware module receives electromagnetic interference under the current ideal working frequency is judged, so that the working stability of the hardware module can be effectively controlled, the stability of electromagnetic interference protection is promoted to be improved, and the probability of electromagnetic interference protection failure caused by failure of a pure hardware electromagnetic interference protection method can be effectively reduced.
The following layout is a next level flow chart, which is combined from the embodiments, each from the embodiments as the case may be, but includes at least the upper features, for example:
as shown in fig. 2, on the basis of the embodiment shown in fig. 1, step 101 may include the following steps:
In step 1011, the ideal working frequency point of the hardware module is first read from the RAM, and the ideal working frequency point is used as the second working frequency; after the second working frequency is obtained, if the second working frequency is a digital signal, the digital signal corresponding to the second working frequency needs to be converted into an analog signal through a digital-to-analog converter, then a model signal corresponding to the second working frequency is input into the voltage-controlled oscillator, a sine wave with the second working frequency is obtained, and the obtained sine wave is used as the second signal. And if the second working frequency is represented by an analog signal, directly inputting the analog signal corresponding to the second working frequency into the voltage-controlled oscillator to obtain a sine wave with the second working frequency and using the sine wave as the second signal.
In this embodiment of the application, in step 1012, the actual working frequency point of the hardware is obtained through a real-time detection manner, and the obtained actual working frequency point is used as the first working frequency, and then the analog signal corresponding to the first working frequency is input into the voltage-controlled oscillator, so as to obtain a sine wave with the frequency of the first working frequency and use the sine wave as the first signal.
Specifically, after the first signal is acquired, the first signal and the second signal are input to the mixer, an intermediate frequency signal corresponding to the first signal and the second signal is obtained, and the obtained intermediate frequency signal is used as the third signal.
For example, referring to fig. 3, if the hardware module is a positioning sensor, an ideal operating frequency of the positioning sensor is f1, since f1 is usually stored as a digital signal, f1 needs to be converted from the digital signal to an analog signal to obtain an analog signal corresponding to f1, the analog signal corresponding to f1 is the second operating frequency 31, and then the analog signal corresponding to f1 is input to the voltage-controlled oscillator 32, and the voltage-controlled oscillator 32 functions to output a sine wave with a frequency of f1, that is, the second signal 320 to the mixer 33; at this time, the first signal 30 detected in real time is also input to the mixer 33.
If the first operating frequency corresponding to the first signal 30 is f2, when both the first signal 30 and the second signal 320 are input to the mixer 33, the mixer 33 processes the first signal 30 and the second signal 320 to obtain intermediate frequency signals of f1-f2, and uses the intermediate frequency signals as the third signal.
In the embodiment of the present application, the first signal and the second signal are input to the mixer to obtain the third signal, and due to the action of the mixer, the first signal can be moved to the position of the intermediate frequency without distortion, so that in the subsequent processing process performed on the basis of higher accuracy of the first signal, the accuracy of the subsequently processed data is also higher.
In the embodiment of the present application, on the basis of the embodiment shown in fig. 1, step 102 may include the following steps:
step 1021, inputting the third signal into a low-pass filter to obtain a low-pass filtered fourth signal;
specifically, the fourth signal is obtained by low-pass filtering the third signal with the low-pass filter.
Step 1022, inputting the fourth signal into an envelope detector, and determining the first amplitude.
Specifically, after the fourth signal is obtained, the amplitude of the fourth signal is obtained, and the amplitude of the fourth signal is taken as the first amplitude.
In this embodiment, after the first signal and the second signal are input to a mixer and the third signal is determined, the third signal is input to a low-pass filter for low-pass filtering, so as to obtain the fourth signal.
In an embodiment of the present application, a center frequency of the low-pass filter is a preset fixed value, when the frequency of the third signal is greater than the signal with the preset fixed value, the signal with the frequency of the third signal not greater than the preset fixed value can normally pass through the low-pass filter.
In the embodiment of the present application, the preset fixed value is usually set according to an empirical value, for example, the preset fixed value may be 10 mhz.
For example, with continued reference to fig. 3, the mixer 33 mixes the first signal 30 and the second signal 320 to obtain a third signal, wherein the first operating frequency f1 of the first signal is 220 mhz, the second operating frequency f2 of the second signal is 200 mhz, and the frequencies f1-f2 of the third signal are 20 mhz. After the third signal is obtained, the third signal is input to the low pass filter 34, the center frequency of the low pass filter 34 is 10 mhz, so the low pass filter 34 prohibits the 10-20 mhz frequency from passing, i.e., filters out the amplitude.
Thus, the center frequency of the low-pass filter is a preset fixed value, when the frequency of the third signal is greater than the preset fixed value, the signal can normally pass through, and the frequency of the third signal is not greater than the preset fixed value, and because the third signal is the intermediate frequency signal of the first signal and the second signal, it is ensured that the intermediate frequency signal not greater than the preset fixed value can normally pass through, the intermediate frequency signal greater than the preset fixed value is filtered, and the difference between the actual working frequency point and the ideal working frequency point of the hardware module is larger if the intermediate frequency signal is larger, otherwise, the difference between the actual working frequency point and the ideal working frequency point of the hardware module is smaller if the intermediate frequency signal is smaller, and the intermediate frequency signal greater than the preset fixed value is filtered, so that the signal when the difference between the actual working frequency point and the ideal working frequency point of the hardware module is larger can be filtered, the signal that ensures when the difference between the actual working frequency point of hardware module and the ideal working frequency point is less can normally pass through, effectively ensures promptly that the actual working frequency of hardware module is in the signal when near the ideal working frequency point can be passed through to and effectively avoid the actual working frequency of hardware module keeps away from signal when the working frequency point forbids to pass through.
In addition, when the actual working frequency of the hardware module is not near the working frequency point, the hardware module is usually in an abnormal working state, and when the actual working frequency of the hardware module is near the working frequency point, the hardware module is usually in a normal working state; therefore, the frequency of detection of the hardware module in abnormal working can be effectively reduced, targeted detection is realized, the frequency of detection is effectively reduced, and the working efficiency of detection is improved.
In another embodiment of the present application, as shown in fig. 4, the step of obtaining the preset condition includes the following steps:
In step 401, since the correspondence between the ideal operating frequency and the amplitude of the hardware module is recorded in the correspondence table, after the second operating frequency is obtained, the second operating frequency is searched from the first correspondence table, the searched amplitude corresponding to the second operating frequency is used as the second amplitude, and the amplitude larger than the second amplitude is used as the preset condition.
In this embodiment of the application, for example, if the second operating frequency f2 is 200 mhz, the amplitude corresponding to 200 mhz is found to be 30dBuV from the correspondence table, and 30dBuV may be used as the second amplitude.
Step 402 is executed, after the second amplitude is obtained in step 401, the preset condition is determined according to the second amplitude, where the preset condition may be that the second amplitude is greater than the preset condition, and that the second amplitude is greater than 30dBuV is determined as the preset condition.
Specifically, when the first amplitude is greater than 30dBuV, it may be determined that the first amplitude satisfies the preset condition; when the first amplitude value is not greater than 30dBuV, it may be determined that the first amplitude value does not meet the preset condition.
For example, with continued reference to fig. 3, after the third signal passes through the low-pass filter 34 in sequence, the fourth signal is obtained, and then the fourth signal is input to the envelope detector 35 for detection, so as to obtain the first amplitude; at this time, since the first amplitude is represented by an analog signal, the first amplitude needs to be analog-to-digital converted by an ADC conversion circuit 37 (analog-to-digital converter) to obtain a digital signal corresponding to the first amplitude; and inputting the obtained digital signal corresponding to the first amplitude into a central processing unit 36, reading the second amplitude from an RAM by the central processing unit 36, judging whether the first amplitude is greater than the second amplitude, if so, judging that the first amplitude meets the preset condition, and adjusting the first working frequency to a third working frequency, wherein the amplitude corresponding to the third working frequency is not greater than the second amplitude.
In addition, after the third operating frequency is determined, an ideal operating frequency corresponding to the third operating frequency is determined from the RAM as the fourth operating frequency, and then the steps 101 and 103 are repeated until the preset condition is not met, without adjusting the frequency
At this time, since the second amplitude is determined according to the second operating frequency and the preset condition is determined based on the second amplitude, as such, it can be deduced that the predetermined condition is determined according to the second operating frequency, and if the predetermined condition is greater than the second amplitude, when it is adhered to that the first amplitude is greater than the second amplitude, it can be known that the amplitude corresponding to the second operating frequency exceeds the amplitude corresponding to the normal operating frequency of the hardware module, it can be known that other hardware causes electromagnetic interference to the hardware module, so that the amplitude of the operating frequency of the hardware module exceeds the limit, and thus, by the method, the condition that other hardware causes electromagnetic interference to the hardware module can be accurately judged in real time, and the phenomenon of electromagnetic interference can be accurately and timely found.
In the embodiment of the present application, referring to fig. 5, a hardware structure corresponding to the frequency adjustment method of the hardware module is provided, wherein the multiple sensors 40, the mobile communication chip 41 and the vehicle body control chip 43 are all connected to the central processing unit 36, so that the central processing unit 36 can obtain the working frequency of each of the multiple sensors 40, the mobile communication chip 41 and the vehicle body control chip 43 in real time. And, the central processing unit 36 is connected to a Random Access Memory (RAM)44, and is configured to store the ideal operating frequency point information of each chip into the RAM 44 in a truth table form, and set a magnitude (limit) corresponding to the ideal operating frequency point of each chip.
Specifically, if the plurality of sensors 40 includes a positioning sensor, an angular velocity sensor, and an acceleration sensor, the data stored in the random access memory 44 is specifically shown in table 1 below:
TABLE 1
The central processing unit 36 is connected to the mixer 33 through the DAC conversion circuit 43, and is configured to perform digital-to-analog conversion on the ideal working frequency point of each chip through the DAC conversion circuit 43 and input the converted ideal working frequency point to the mixer 33; the antenna 45 collects the actual operating frequency of each chip in real time, and then inputs the actual operating frequency of each chip into the mixer 33, so that the intermediate frequency signals of the actual operating frequency point and the ideal operating frequency point of each chip can be obtained through the mixer 33.
Further, after the intermediate frequency signal corresponding to each chip is obtained by the mixer 33, the mixer 33 inputs the intermediate frequency signal of each chip into the envelope detector 34, and the amplitude corresponding to the actual operating frequency of each chip is obtained through the detection function of the envelope detector 34; then, the amplitude corresponding to the actual working frequency of each chip detected by the envelope detector 34 is converted into a digital signal by the ADC conversion circuit 37, and then returned to the central processing unit 36; the central processing unit 36 reads the limit value corresponding to each chip from the random access memory 44, and detects whether the amplitude value corresponding to the actual working frequency of each chip exceeds the corresponding limit value; and for each chip, if the amplitude corresponding to the actual working frequency of the chip exceeds the corresponding limit value, adjusting the working frequency of the chip until the amplitude corresponding to the adjusted working frequency does not exceed the corresponding limit value, ensuring that the adjusted working frequency is within a set working frequency range corresponding to the normal work of the chip, and taking the adjusted working frequency as the third working frequency.
For example, taking the mobile communication chip 41 as an example, when the cpu 36 receives the maximum amplitude P corresponding to the actual operating frequency of the mobile communication chip 41 detected by the envelope detector 34, at this time, the cpu 36 reads the out-of-limit amplitude D1 corresponding to the mobile communication chip 41 from table 1 in the random access memory 44, and if P > D1, adjusts the operating frequency of the mobile communication chip 41 until the amplitude corresponding to the adjusted operating frequency does not exceed D1, and ensures that the adjusted operating frequency is within the set operating frequency range corresponding to the normal operation of the mobile communication chip 41, at this time, the adjusted operating frequency is taken as the third operating frequency.
Therefore, by the above mode, when the amplitude corresponding to the actual working frequency of one chip is detected to exceed the corresponding limit value, the working frequency of the chip is adjusted until the amplitude corresponding to the adjusted working frequency does not exceed the corresponding limit value, and the adjusted working frequency is ensured to be within the set working frequency range corresponding to the normal work of the chip.
