Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a parameter correction method according to an embodiment of the present invention, where the present embodiment is applicable to a case where parameters are corrected quickly and accurately through two correction processes, and the method can be executed by a parameter correction apparatus according to an embodiment of the present invention, where the parameter correction apparatus can be implemented by software and/or hardware, and can be generally integrated in a computer device. Accordingly, as shown in fig. 1, the method comprises the following operations:
and S110, acquiring an initial deviation value between the initial parameter value of the target parameter and the standard parameter value.
The target parameter may be any parameter of the device that can be corrected, for example, the frequency of a crystal oscillator in a remote control of an automobile. The initial parameter value may be a parameter value of the target parameter at the initial time of the current correction, may be a parameter value of the target parameter measured at the initial time of the correction, and may be determined by related hardware in the device. The standard parameter value may be a parameter value of a target parameter for optimizing a corresponding performance of the device, and may be preset according to a functional characteristic of the device, for example, a crystal oscillator frequency for setting a transmission frequency of the car remote controller at a reception peak of a receiving end of the car device. The initial deviation value may be data indicative of a degree of numerical difference between the initial parameter value and the standard parameter value.
Correspondingly, after the target parameter of the device is corrected, the initial parameter value of the target parameter can be measured by any method which can be realized, and the obtained initial parameter value and the standard parameter value are compared and calculated to obtain the initial deviation value between the initial parameter value and the standard parameter value of the target parameter. The degree of difference between the initial parameter value and the standard parameter value, i.e., the degree of deviation of the target parameter at the initial time of correction, may be determined based on the initial deviation value. Alternatively, the initial deviation value may be the difference of the initial parameter value minus the standard parameter value.
And S120, correcting the target parameter according to the initial deviation value, and acquiring an initial correction parameter value of the corrected target parameter.
The initial correction parameter value may be a parameter value of the target parameter after the target parameter is corrected according to the initial deviation value, or may be a parameter value of the target parameter measured after the target parameter is corrected according to the initial deviation value.
Accordingly, since the degree of difference between the initial parameter value and the standard parameter value can be determined according to the initial deviation value, the intensity of correcting the target parameter can be determined according to the initial deviation value, and the target parameter is corrected with the intensity, so that the parameter value of the target parameter can be changed to a proper extent, thereby being close to the standard parameter value to a great extent. And measuring the parameter value of the corrected target parameter to obtain the initial correction parameter value of the target parameter.
Illustratively, the standard parameter value of the crystal oscillator frequency in the automobile remote controller may be 18.0MHz of the frequency of the receiving peak of the receiving end of the in-vehicle device, and the initial parameter value may be 22.375MHz, so that the initial offset value may be obtained as the difference between the initial parameter value and the standard parameter value, which is 4.375MHz, and further the target parameter value may be reduced by 4MHz according to the initial offset value, so that the target parameter is corrected to 18.375MHz to a large extent and is close to 18.0MHz to a large extent.
And S130, acquiring a correction deviation value between the initial correction parameter value and the standard parameter value.
Wherein the correction deviation value may be data indicative of a degree of numerical difference between the initial correction parameter value and the standard parameter value.
Correspondingly, the initial correction parameter value and the standard parameter value are compared and calculated to obtain the correction deviation value between the initial correction parameter value and the standard parameter value of the target parameter. The degree of difference between the initial correction parameter value and the standard parameter value, i.e. the degree of deviation that the target parameter after correction according to the initial deviation value still has, can be determined from the correction deviation value. Alternatively, the correction deviation value may be the difference of the initial correction parameter value minus the standard parameter value.
Illustratively, in the above example of the automobile remote controller, the correction deviation value is obtained as the difference between the initial correction parameter value 18.375MHz minus the standard parameter value 18.0MHz, which is 0.375 MHz.
S140, correcting the target parameter according to the correction deviation value to obtain the target parameter with a target correction parameter value.
The target correction parameter value may be a parameter value of a target parameter that enables the corresponding performance of the device to reach a normal operating state, may be preset according to a functional characteristic of the device and/or a standard parameter value, and may have a difference value within a reasonable range with the standard parameter value, for example, may be a crystal oscillator frequency that enables the transmission frequency of the car remote controller to be within a receiving frequency range of the receiving end of the car device.
Correspondingly, because the difference degree between the initial correction parameter value and the standard parameter value can be determined according to the correction deviation value, the intensity for further correcting the target parameter can be determined according to the correction deviation value, the target parameter is corrected by the intensity, the parameter value of the target parameter can be further changed to reach the target correction parameter value, so that the target correction parameter value is more accurately close to the standard parameter value, and the parameter value deviation of the target parameter is in a reasonable range. Specifically, since the initial correction parameter value is already close to the standard parameter value to a great extent, in the process of correcting the target parameter according to the correction deviation value, correction with smaller amplitude step by step can be performed, so that the parameter value of the target parameter changes with small amplitude for many times until the target correction parameter value is reached, and accurate parameter correction is realized.
Illustratively, in the above example of the automobile remote controller, the correction deviation value is 0.375MHz, and the target correction parameter value 18.025MHz can be obtained after five times of fine correction in a manner that the amplitude of 0.07MHz is gradually reduced, and 18.025MHz is in the receiving frequency range of the receiving end with the receiving peak value of 18 MHz.
The embodiment of the invention provides a parameter correction method, which comprises the steps of comparing an initial parameter value of a target parameter with a standard parameter value to obtain an initial deviation value, correcting the target parameter according to the initial deviation value, comparing the initial correction parameter value with the standard parameter value again after obtaining an initial correction parameter value of the corrected target parameter, and performing secondary correction on the target parameter according to the correction deviation value after obtaining a correction deviation value so as to correct the target parameter into a target correction parameter value, thereby realizing quick and accurate correction of the parameter by executing two correction processes and simultaneously ensuring the production speed and the production yield of equipment.
Example two
Fig. 2 is a flowchart of a parameter correction method according to a second embodiment of the present invention. The embodiment of the present invention is embodied on the basis of the above-described embodiment, and in the embodiment of the present invention, a specific optional implementation manner is provided for correcting the target parameter according to the initial deviation value and obtaining an initial correction parameter value of the corrected target parameter.
As shown in fig. 2, the method of the embodiment of the present invention specifically includes:
s210, acquiring an initial deviation value between an initial parameter value and a standard parameter value of the target parameter.
S220, correcting the target parameter according to the initial deviation value, and acquiring an initial correction parameter value of the corrected target parameter.
In an optional embodiment of the present invention, S220 may specifically include:
and S221, inquiring a preset inquiry table according to the initial deviation value, and determining a basic correction coefficient according to an inquiry result.
The preset lookup table may be a data table for determining the intensity of correction of the target parameter according to the initial deviation value. The base correction factor may be data characterizing the strength of correction to the target parameter.
Accordingly, the preset lookup table may be preset and stored according to a history of correcting the target parameter, for example, when the initial parameter values corresponding to different initial deviation values are corrected to be standard parameter values, and the correction intensities of the target parameter may be stored in the preset lookup table corresponding to the correction coefficients representing the correction intensities and the initial deviation values, respectively. Further, when the preset lookup table is queried according to the initial deviation value, the basic correction coefficient corresponding to the initial deviation value can be obtained according to the query result.
In an optional embodiment of the present invention, the querying the preset lookup table includes a set number of parameter deviation intervals, and a one-to-one mapping relationship exists between each of the parameter deviation intervals and the set number of preset correction coefficients; the obtaining a basic correction coefficient according to the initial deviation value may include: determining a target parameter deviation interval matched with the initial deviation value in a preset lookup table; and inquiring a preset correction coefficient which has a one-to-one mapping relation with the target parameter deviation interval in the preset inquiry table, and determining the preset correction coefficient as a basic correction coefficient.
The parameter deviation intervals can be any interval in a possible value range of the initial deviation value, the sum of the parameter deviation intervals with the set number can cover all the value ranges of the initial deviation value, and the parameter deviation intervals are not overlapped. The preset correction coefficient having a one-to-one mapping relationship with an arbitrary parameter deviation section may be a correction coefficient for correcting a target parameter having an initial parameter value corresponding to an initial deviation value in the parameter deviation section.
Correspondingly, the parameter deviation intervals can be preset as required, the more the number of the set parameter deviation intervals is, namely the smaller the range of each parameter deviation interval is, the higher the accuracy of correcting the target parameter according to the inquired basic correction coefficient is. The preset correction coefficient having a one-to-one mapping relationship with each parameter deviation interval may be determined according to a history of correction of the target parameter, for example, for any one parameter deviation interval, when an initial deviation value between an initial parameter value of the target parameter and a standard parameter value belongs to the interval, a correction coefficient corresponding to a total correction intensity in a process of correcting the target parameter from the initial parameter value to the target correction parameter value is recorded, and after a plurality of correction coefficients corresponding to the initial deviation values in the interval are obtained, an average value of the plurality of correction coefficients may be calculated as the preset correction coefficient having a one-to-one mapping relationship with the parameter deviation interval. Therefore, the preset correction coefficients having a one-to-one mapping relationship with the parameter deviation intervals can respectively correct the initial parameter values corresponding to the initial deviation values in the parameter deviation intervals, so that the target parameter can be corrected from the initial parameter values to values very close to the target correction parameter values, for example, the integral digits can be corrected to be consistent with the target correction parameter values, and only the deviation of the decimal digits is reserved.
Illustratively, table 1 is a schematic diagram of a specific preset lookup table according to an embodiment of the present invention. In the above example of the automobile remote controller, when the initial deviation value is 4.375MHz, as shown in table 1, it may be determined that the matched parameter deviation interval is 4-6 MHz in the preset lookup table, then the preset correction coefficient may be queried to be-2, and the basic correction coefficient is determined to be-2, then the parameter may be transmitted to a frequency correction circuit deployed in the automobile remote controller, and the frequency correction circuit may correct the crystal oscillator frequency from the initial parameter value of 22.375MHz to the initial correction parameter value of 18.375MHz according to the basic correction coefficient-2, which is largely close to the standard parameter value of 18.0 MHz.

| -4～-6 | 2 |
S222, correcting the target parameter according to the basic correction coefficient, and acquiring an initial correction parameter value of the corrected target parameter.
Accordingly, the specific method for correcting the target parameter according to the basic correction coefficient may be determined according to the correction mode of the target parameter, which is not limited in this embodiment. For example, in the case of the above-mentioned car remote controller, the frequency correction of the crystal oscillator can be realized by introducing the basic correction coefficient into the deployed frequency correction circuit.
And S230, acquiring a correction deviation value between the initial correction parameter value and the standard parameter value.
S240, correcting the target parameter according to the correction deviation value to obtain the target parameter with a target correction parameter value.
In an optional embodiment of the present invention, correcting the target parameter according to the correction deviation value to obtain a target parameter with a target correction parameter value may include: and under the condition that the correction deviation value is determined not to be within the deviation allowable range, gradually correcting the target parameter according to preset correction precision to obtain the target parameter with the target correction parameter value.
The allowable deviation range may be a numerical range formed by deviation values between all target parameter values and standard parameter values, which enable the device to normally implement corresponding functions, and may be preset. The preset correction accuracy may be a preset correction strength for the target parameter at each correction in the stepwise correction process. Accordingly, the target correction parameter value may be any value having a deviation value from the standard parameter value within a deviation allowable range.
Correspondingly, if the correction deviation value is not within the deviation allowable range, it can be shown that the current target parameter with the preliminary correction parameter value still cannot enable the device to function as expected, and further correction needs to be performed on the target parameter. Furthermore, because the initial correction parameter value obtained after correction according to the initial deviation value is close to the standard parameter value to a certain extent, a gradual correction method can be adopted, the target parameter is corrected with preset correction precision in each correction, and the correction is repeated for a plurality of times until the target parameter is corrected to the target correction parameter value, namely the deviation value between the target parameter value and the standard parameter value is within the allowable deviation range, so that the equipment can realize functions as expected.
Alternatively, in the case where it is determined that the test deviation value is within the deviation allowable range, the target parameter correction may be completed.
In an optional embodiment of the present invention, correcting the target parameter according to the correction deviation value to obtain a target parameter with a target correction parameter value may include: under the condition that the correction deviation value is determined not to be within the deviation allowable range, gradually adjusting the basic correction coefficient according to preset adjustment precision until the target correction coefficient is obtained; and correcting the target parameters according to the target correction coefficient to obtain the target parameters with target correction parameter values.
The preset adjusting precision may be a preset adjusting amount of the basic correction coefficient adjusted each time in the step-by-step adjusting process. The target correction coefficient may be data characterizing a correction strength with which the target parameter is corrected from the initial parameter value to the target correction parameter value.
Correspondingly, when the target parameter is corrected according to the initial deviation value, a basic correction coefficient is determined according to the initial deviation value, if the target parameter is corrected from the initial parameter value to the initial correction parameter value according to the basic correction coefficient, and the correction deviation value between the basic correction coefficient and the standard parameter value is not in the deviation allowable range, the correction strength represented by the basic correction coefficient is larger or smaller, so that the target parameter cannot be corrected to be the target correction parameter value, and therefore the basic correction coefficient can be adjusted to change the correction strength of the target parameter represented by the basic correction coefficient by adjusting the size of the basic correction coefficient. Further, since the target parameter correction strength represented by the basic correction coefficient can enable the preliminary correction parameter value of the corrected target parameter to approach the standard parameter value to a certain extent, that is, the basic correction coefficient approaches the target correction coefficient to a certain extent, a gradual adjustment method can be adopted, the basic correction coefficient is adjusted with preset adjustment accuracy each time, and the adjustment is repeated for multiple times until the basic correction coefficient is corrected to the target correction coefficient, that is, the target parameter is adjusted according to the target correction coefficient, so that the target parameter can be corrected from the preliminary parameter value to the target correction parameter value, that is, the deviation value between the target parameter value and the standard parameter value is within the deviation allowable range, and the device can realize the function as expected.
In an optional embodiment of the present invention, the gradually adjusting the basic correction coefficient according to a preset adjustment precision until a target correction coefficient is obtained may include: determining preset adjustment accuracy as the numerical variation of single adjustment of the basic correction coefficient; and repeatedly executing the single adjustment on the basic correction coefficient, correcting the target parameter according to the test correction coefficient obtained after the single adjustment, and acquiring a test deviation value between the corrected test parameter value of the target parameter and the standard parameter value until the test correction coefficient is determined to be the target correction coefficient under the condition that the test deviation value is determined to be within the deviation allowable range.
Wherein, the value change amount can be a value which is increased or decreased after a single adjustment of the basic correction coefficient. The test correction factor may be a value of the base correction factor after each single adjustment. The test parameter value may be a parameter value of the target parameter after the target parameter is corrected according to the test correction coefficient. The test deviation value may be data indicative of a degree of numerical difference between the test parameter value and the standard parameter value.
Correspondingly, the preset adjustment precision is determined as the variation of the basic correction coefficient in single adjustment, the test correction coefficient is obtained after each single adjustment, the target parameter is corrected according to the test correction coefficient, the target parameter can be corrected to the test parameter value, the test deviation value between the test parameter value and the standard parameter value is obtained, and whether the current test deviation value can enable the equipment to realize the function as expected or not can be determined according to whether the test deviation value is within the deviation allowable range or not. Specifically, if the test deviation value is not within the deviation allowable range, the basic correction coefficient needs to be further adjusted, and the above steps may be repeated until the obtained test deviation value enters the deviation allowable range, and the test correction coefficient at this time is determined as the target correction coefficient.
In an optional embodiment of the invention, the test parameter value is positively correlated with the base correction factor; the single adjustment of the base correction factor may include: under the condition that the test parameter value is determined to be larger than the standard parameter value according to the test deviation value, subtracting the numerical value variation from the basic correction coefficient to obtain a test correction coefficient obtained after the single adjustment; and under the condition that the test parameter value is smaller than the standard parameter value according to the test deviation value, increasing the numerical variation of the basic correction coefficient to obtain the test correction coefficient obtained after the single adjustment.
Correspondingly, if the test parameter value is positively correlated with the basic correction coefficient, the basic correction coefficient is increased, and the test parameter value is increased, otherwise, the basic correction coefficient is decreased, and the test parameter value is decreased. Therefore, when the test parameter value is determined to be in positive correlation with the basic correction coefficient, the magnitude relationship between the test parameter value and the standard parameter value can be determined according to the test deviation value, so that the test parameter value is determined to be increased or decreased, and the corresponding basic correction coefficient is correspondingly increased or decreased.
For example, in the above example of the automobile remote controller, it can be known from table 1 that the basic correction coefficient is positively correlated with the parameter value of the target parameter. The crystal oscillator frequency is corrected from the initial parameter value of 22.375MHz to the initial correction parameter value of 18.375MHz according to the basic correction coefficient-2, and the correction deviation value is 0.375 MHz. If the deviation allowable range is-0.2 MHz, the correction deviation value is determined not to be within the deviation allowable range. Further, the preset adjustment accuracy of the basic correction coefficient can be set to 0.1, when the current parameter value is determined to be greater than the standard parameter value according to the correction deviation value, the basic correction coefficient is reduced by 0.1 to obtain a test correction coefficient-2.1, the test correction coefficient-2.1 is transmitted into the frequency correction circuit, the frequency of the crystal oscillator can be adjusted downwards by 0.5 to obtain a test parameter value 17.875MHz, the test deviation value is-0.125 MHz compared with the standard parameter value, and the frequency correction of the crystal oscillator is completed within a deviation allowable range.
In an optional embodiment of the present invention, in a case where it is determined that the test deviation value is within the deviation allowable range, the base correction coefficient is determined as the target correction coefficient.
Fig. 3 is a schematic flow chart of a parameter correction method according to a second embodiment of the present invention. In a specific example, as shown in fig. 3, the frequency of the crystal oscillator in the remote controller of the vehicle is corrected, and the current frequency of the crystal oscillator is read first, and a deviation value between the actual value of the current frequency and the target is calculated, so as to determine the correction coefficient according to the deviation value. After frequency correction is carried out according to the correction coefficient, reading the current frequency again, calculating a deviation value, judging whether the deviation value is within an allowable range, if so, finishing correction, and storing a result; otherwise, entering a cyclic fine adjustment process of the correction coefficient until the deviation value enters an allowable range, finishing correction, and storing a result.
The embodiment of the invention provides a parameter correction method, which comprises the steps of comparing an initial parameter value of a target parameter with a standard parameter value to obtain an initial deviation value, correcting the target parameter according to the initial deviation value, comparing the initial correction parameter value with the standard parameter value again after obtaining an initial correction parameter value of the corrected target parameter, and performing secondary correction on the target parameter according to the correction deviation value after obtaining a correction deviation value so as to correct the target parameter into a target correction parameter value, thereby realizing quick and accurate correction of the parameter by executing two correction processes and simultaneously ensuring the production speed and the production yield of equipment; furthermore, the intensity of correcting the initial parameter value is determined based on the preset lookup table, large-range quick adjustment of the target parameter value can be realized by preliminarily correcting the target parameter, and the parameter correction efficiency is greatly improved.
