Example one
Fig. 1 is a flowchart of a clock chip frequency compensation method according to an embodiment of the present invention, where the method is applicable to frequency compensation of a clock chip, and the method may be implemented by a clock chip frequency compensation device, where the clock chip frequency compensation device may be implemented in a form of hardware and/or software, and the clock chip frequency compensation device may be configured in a computer device such as a server.
The clock chip is a low-power consumption real-time clock chip, and the requirement of high accuracy low-power consumption needs to be satisfied when using, because the 32K tuning fork crystal in the clock chip can be influenced by temperature variation, its oscillation frequency can change along with the temperature to lead to the clock chip timing inaccurate. Therefore, it is necessary to detect the temperature change of the clock chip. The frequency deviation condition is determined according to the temperature change condition, so that the frequency of the clock chip in different temperature states is compensated, and the clock chip can continuously meet the requirement of high precision during working. In view of this, embodiments of the present invention provide a clock chip frequency compensation scheme, which periodically detects a temperature value of a clock chip to perform frequency compensation on the clock chip in different detection periods, so that the clock chip meets requirements of high precision and low power consumption.
Referring to fig. 1, a clock chip frequency compensation method according to an embodiment of the present invention includes:
s110, obtaining a historical temperature value obtained by detecting a clock chip in a historical detection period.
The historical detection period indicates that a corresponding historical temperature value can be obtained every detection period when the clock chip works, the current historical detection period consists of two or more continuous detection periods, one detection period can be understood as a time period, namely, after the historical temperature values corresponding to at least two continuous time periods are accumulated, the subsequent steps are convenient to execute, and the advantage of the method is that the accuracy of frequency compensation of the clock chip in the subsequent steps is ensured.
In the historical detection period, the time period corresponding to each detection period is not necessarily the same, and the next detection period needs to be determined together with the precision grade of the clock chip in the subsequent step.
Alternatively, the historical temperature value is obtained by: acquiring a simulated temperature value obtained by detecting a clock chip in a historical detection period; and performing analog-to-digital conversion on the simulated temperature value to obtain a historical temperature value.
The simulated temperature value can be obtained by a temperature detection module integrated in the clock chip, and the temperature detection module can be realized by a temperature sensor. Because the temperature obtained by the temperature sensor is an analog temperature value, the analog temperature value can be converted into a digital temperature value by integrating an analog-to-digital conversion module in the clock chip, so that a historical temperature value corresponding to each historical detection period is obtained. The Analog conversion module can be implemented by an Analog-to-digital converter (ADC for short).
And S120, determining the current detection period according to the historical temperature value and the precision level of the clock chip.
The precision level of the clock chip represents the allowable deviation of the measured actual value and the standard value, and the current actual value and the standard value refer to the actual output frequency and the standard output frequency of the clock chip at the same temperature, namely the nominal frequency variation, and the unit is one part Per Million (Parts Per Million, abbreviated as PPM).
Generally, the precision grade requirement of the clock chip is different according to different use occasions of the clock chip, and the precision grade can be set to be +/-2 PPM within the range of 0 ℃ to +40 ℃ for example; the accuracy grade can be set to be +/-3.5 PPM and the like within the range of-40 ℃ to +0 ℃. The precision grade of the clock chip can be set when the clock chip leaves a factory, and can also be adjusted according to different requirements of customers, and the current adjustment mode can be defined by the customers through software. The setting mode and the precision grade range of the precision grade of the specific clock chip are not limited herein, and the actual requirements are taken as the standard.
Optionally, when the current detection period is determined according to the historical temperature value and the precision level of the clock chip, a frequency compensation error corresponding to the historical temperature value needs to be determined, and the frequency compensation error and the precision level of the clock chip can be compared to determine the current detection period.
The frequency compensation error can be obtained by obtaining corresponding historical temperature values according to at least two continuous detection periods in the historical detection periods. The purpose of determining the frequency compensation error is to determine the frequency compensation error in the process of the last detection period through at least two historical temperature values, so that the current detection period is determined according to the current frequency compensation error and the precision grade of the clock chip, and the accuracy of frequency compensation in the process of obtaining the current temperature value through the current detection period is further ensured.
S130, acquiring a current temperature value obtained by detecting the clock chip in the current detection period.
After the current detection period, the current temperature value corresponding to the current detection period can be directly obtained, and the method for obtaining the current temperature value is the same as the method for obtaining the historical temperature value, which is not repeated herein.
And S140, performing frequency compensation on the clock chip based on the current temperature value.
After the current detection period is determined based on the historical temperature value and the precision grade of the clock chip, in the process of obtaining the current temperature value according to the current detection period, the frequency compensation mode of the clock chip can be that after the actual output frequency corresponding to the current temperature value is obtained, the standard output frequency corresponding to the current temperature value is further obtained, and the actual output frequency and the standard output frequency are compared, so that the frequency compensation is carried out on the clock chip based on the standard output frequency.
The clock chip frequency compensation method provided by the embodiment of the invention comprises the steps of firstly, acquiring historical temperature values obtained by detecting a clock chip in a historical detection period; then determining the current detection period according to the historical temperature value and the precision grade of the clock chip; then obtaining a current temperature value obtained by detecting the clock chip in the current detection period; and finally, performing frequency compensation on the clock chip based on the current temperature value. By using the scheme, the detection period of the clock chip can be adaptively adjusted according to the precision grade of the clock chip, and the problems of high power consumption, resource waste and the like caused by the fact that the clock chip has various grade requirements in the same application scene in the existing scheme are solved.
Example two
Fig. 2 is a flowchart of a clock chip frequency compensation method according to a second embodiment of the present invention, and the relationship between the present embodiment and the above embodiments is to refine the features of the corresponding steps. As shown in fig. 2, the method includes:
s210, obtaining a historical temperature value obtained by detecting a clock chip in a historical detection period.
And S220, determining a frequency compensation error according to the historical temperature value.
In a measuring circuit in which a clock chip operates, real-time frequency compensation is generally not performed on the clock chip, for example, the temperature of the clock chip is not measured every 1s, so that frequency compensation is performed according to the current temperature, and due to the fact that the workload of the method is large, and the frequency error in a short time is generally within an allowable range. Therefore, the temperature of the clock chip is usually detected in a mode of detecting every certain detection period, and then the frequency compensation error in the detection period process is determined, so that the accuracy of subsequent temperature frequency measurement is judged according to the current frequency error, and the working accuracy of the clock chip is ensured.
Alternatively, determining the frequency compensation error from the historical temperature value may be represented by the expression:
σ＝a*|(T1-t)2-(T2-t)2| (1)
wherein, σ represents the frequency compensation error, α represents a first preset parameter, T represents a second preset parameter, the historical detection period includes a first detection period and a second detection period, the second detection period is a previous detection period of the first detection period, the first detection period is a previous detection period of the current detection period, T1 represents a historical temperature value detected by the second detection period, and T2 represents a historical temperature value detected by the first detection period.
The first preset parameter a represents a mouth opening coefficient of the clock crystal, the second preset parameter t represents time corresponding to a vertex frequency in the temperature frequency relation information, and the temperature frequency relation information is standard output frequency which is stored in the clock chip in advance and corresponds to each temperature value. The first preset parameter a and the second preset parameter t are constants, and specific values are not limited herein.
And S230, acquiring the adjustment step size of the frequency compensation error.
The adjustment step size is generally set according to the user's requirement, and may be set to 1 second for example. The purpose of obtaining the adjustment step size of the frequency compensation error is to adjust the historical detection period according to the adjustment step size, which is helpful for the subsequent steps to more accurately determine the current detection period.
And S240, determining the current detection period according to the frequency compensation error, the adjustment step size and the precision level.
Optionally, determining the current detection period according to the frequency compensation error, the adjustment step size, and the precision level includes:
judging whether the frequency compensation error exceeds the precision level; if the precision grade is not exceeded, the current detection period is equal to the first detection period plus the adjustment step length; and if the precision level is exceeded, the current detection period is equal to the first detection period minus the adjustment step length.
And (3) setting the precision grade as delta, judging the sizes of the sigma and the delta obtained according to the formula (1), if the frequency compensation error does not exceed the precision grade, indicating that the compensation precision of the frequency compensation error in the historical detection period is accurate enough, properly prolonging the detection time of the detection period, and enabling the current detection period to be equal to the first detection period plus the adjustment step length. Let the current detection period be ω2The first detection period is ω1Then the current detection period can be expressed as: omega2＝ω1+ Delta; if the frequency compensation error exceeds the precision grade, it indicates that the compensation precision of the frequency compensation error in the historical detection period does not meet the requirement corresponding to the precision grade, and the detection time of the detection period can be adaptively shortened, and then the current detection period can be represented as: omega2＝ω1-Δ。
And S250, acquiring the current temperature value obtained by detecting the clock chip in the current detection period.
And S260, acquiring the actual output frequency corresponding to the current temperature value.
When the frequency compensation is performed on the clock chip according to the current temperature value, the actual output frequency corresponding to the current temperature value needs to be obtained first, and the current actual output frequency can be directly obtained by monitoring the oscillation condition of the clock crystal.
And S270, acquiring the standard output frequency corresponding to the current temperature value from the temperature frequency relation information.
The temperature frequency relation information includes standard output frequencies corresponding to the temperature values. The temperature frequency relation information can be stored in the clock chip in advance, so that the standard output frequency of the current temperature value to one can be directly obtained when the current temperature value is obtained.
The temperature frequency relation information can be stored in a clock chip in a curve form, namely, the standard output frequency corresponding to each temperature value is described in a curve form to form a temperature frequency characteristic curve; or storing in an array form, that is, an array is formed by a temperature value and a corresponding standard output frequency, so as to form a temperature frequency relation table. The storage form of the specific temperature frequency relation information in the clock chip is not limited herein.
And S280, performing frequency compensation on the clock chip according to the actual output frequency and the standard output frequency.
And judging a compensation range needing frequency compensation according to the actual output frequency and the standard output frequency corresponding to the current temperature value, so that the output frequency of the current temperature value approaches the standard output frequency, and the accuracy of the clock chip in working is ensured.
Accordingly, when step S210 is executed, in the historical monitoring period, when a corresponding historical temperature value is obtained every time one monitoring period passes, the clock chip is frequency compensated according to the actual output frequency and the standard output frequency corresponding to the historical temperature value, so as to ensure the accuracy of the output frequency corresponding to the temperature value obtained every time one monitoring period passes.
Optionally, frequency compensating the clock chip according to the actual output frequency and the standard output frequency includes: determining a frequency error according to the actual output frequency and the standard output frequency; and when the frequency error exceeds a preset error value, performing frequency compensation on the clock chip based on the frequency error.
The current frequency error may be set according to different requirements of a user, for example, 1%, 3%, or 5%, and the specific value of the frequency error is not limited herein.
And when the actual output frequency and the standard output frequency exceed the frequency error value, performing frequency compensation on the clock chip based on the frequency error. When frequency compensation is carried out, compensation can be carried out according to the minimum value, the maximum value or the intermediate value in the frequency error range, and in order to ensure the accuracy of temperature frequency detection when a subsequent detection period is determined according to the current temperature value, the actual output frequency can be compensated to be the standard output frequency. Accordingly, when the frequency error does not exceed the preset error value, the frequency compensation is not performed on the clock chip. Namely, the actual output frequency corresponding to the current temperature value is the standard output frequency.
It is to be noted that, when the clock chip works, the process of periodically compensating the frequency of the clock chip by determining a new detection period is not required, because the temperature of the clock chip gradually tends to be stable along with the working condition, the corresponding frequency compensation error also tends to be stable, and when the subsequent detection period is determined according to the frequency compensation error, the adjustment step length and the precision grade, the detection period also tends to be the same gradually, thereby ensuring the stable operation of the clock chip.
The technical scheme provided by the embodiment of the invention can be briefly described as the following process: the precision level of the clock chip is set, and the historical detection period is assumed to comprise a first detection period and a second detection period. Obtaining an initial temperature value of the clock chip when the clock chip starts to work, and obtaining a first historical temperature value t1 after analog-to-digital conversion; calculating a frequency error based on the actual output frequency of t1, and starting frequency compensation on the t1 temperature; during the first detection period omega1Then, a second historical temperature value t2 can be obtained, and frequency compensation for the temperature t2 is started (the compensation mode is the same as that of t 1), wherein the current first detection period can be set according to the experience of technicians or can be set as a default period; calculating frequency compensation errors according to the measured t1 and t2, wherein the time point t1 and the time point t2 are standard frequencies which are already compensated, the current frequency compensation error is the frequency compensation error in the time period from t1 to t2, and the second detection period omega is determined again according to the relation between the frequency compensation error and the precision grade2，ω2＝ω1- Δ, or ω2＝ω1+ Δ. During the second detection period omega2And then obtaining a third historical temperature value t3, calculating a current frequency compensation error through the second historical temperature value t2 and the third historical temperature value t3, further re-determining a current detection period according to the relation between the current frequency compensation error and the precision grade, obtaining the current temperature value after the current detection period, repeatedly executing the process of determining the frequency compensation error according to the current temperature value and the previous temperature value, further determining the next detection period, and after determining the next detection period, performing frequency difference compensation on the clock chip based on the next temperature value.
According to the clock chip frequency compensation scheme provided by the embodiment of the invention, the same clock chip can meet scenes with different precision grade requirements, the detection period can be shortened when the high precision is required, the detection period can be expanded when the low precision is required, the precision grade can be set according to the requirements of customers, compared with the existing mode of compensating according to a fixed precision and a fixed period, the power consumption of a compensation circuit can be reduced to more than 70%, and the implementation mode is simpler.
