It should be noted that the scene schematic diagram of the system for adjusting a carrier frequency of a circuit board shown in fig. 1 is merely an example, and the system and the scene for adjusting a carrier frequency of a circuit board described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application.
As shown in fig. 2, fig. 2 is a schematic flowchart of an embodiment of a method for adjusting a carrier frequency of a circuit board in the embodiment of the present application, where the method for adjusting the carrier frequency of the circuit board may include the following steps 201 to 204:
201. and obtaining the inductance value of a circuit board in the air conditioner and the resistance value of a direct current resistor in the circuit board.
In order to improve the power utilization efficiency of the air conditioner, namely under the condition of the same electric quantity, the working efficiency of the air conditioner is higher, and the working efficiency of the air conditioner can be improved by adjusting the PFC carrier frequency of a circuit board in the air conditioner.
However, because the inductance of the circuit board of the air conditioner of different models and the resistance of the dc resistor are not completely the same, the PFC carrier frequencies required by the circuit boards of the air conditioner of different models are also different, and therefore, in order to adjust the PFC carrier frequencies of the circuit boards of the air conditioner of different models, the inductance of the circuit boards of the air conditioner of different models and the resistance of the dc resistor need to be obtained, the method for obtaining the inductance can measure the circuit board by using a multimeter, and then the inductance data of the multimeter is input into the program of the air conditioner, and can also be calculated by using a formula, for example: z =2 pi fL (wherein Z is inductive reactance pi is a circumferential rate, f is an alternating current frequency, and L is an inductance), and because different air conditioners can determine the model of the corresponding circuit board when the corresponding circuit board is selected, the specific inductive reactance of the corresponding circuit board can be known, and the specific value of Z can be known; in cities, the alternating current is generally 220V, the frequency is 50Hz, and therefore the specific index of f can be known; the circumferential ratio is constant, so that the specific index of pi can be known, and in this case, only one unknown number L is existed in the formula, so that the specific data of L can be calculated. The method for obtaining the resistance value of the direct current resistor can also be used for directly measuring the resistance value of the direct current resistor of the circuit board through a universal meter and inputting the resistance value into a program; the resistance of the dc resistor can also be calculated according to the formula, for example: p = U 2 The rated power of the air conditioner is designed according to the design of different air conditioners, so that the specific value of P can be known according to different models; the household voltage in the city is 220V, and only R is an unknown number, so that the specific value of R can be calculated according to a formula.
It should be noted that the method for obtaining the inductance and the resistance of the dc resistor mentioned in this step is only one of many methods, and does not constitute a limitation to the embodiments of the present application.
202. And comparing the inductance value with a preset inductance threshold value to obtain an inductance comparison result.
After the corresponding inductance is obtained in step 201, the obtained inductance needs to be determined, so as to determine specific properties of the circuit board in the current air conditioner, where the properties may refer to specific models of the circuit board, for example, when the obtained inductance is 7mH, if the obtained inductance is compared with a preset inductance threshold value of 8mH, the inductance comparison result of 7mH and 8mH may be obtained, and if the air conditioner smaller than 8mH belongs to a 1P machine (the 1P machine is an air conditioner with an input power of about 750W and an output power of about 2300W to 2500W), the circuit board used by the current circuit board 1P machine may be determined.
In order to better understand the embodiment of the present application, in the embodiment of the present application, the comparing the inductance value with a preset inductance threshold value to obtain an inductance comparison result includes:
and comparing the inductance value with a relation between a first preset inductance threshold value and a second preset inductance threshold value, wherein the first preset inductance threshold value is smaller than the second preset inductance threshold value.
For accurate comparison of the nodes, the inductance threshold may be set to 2 at this time, threshold a and threshold B, where threshold a is smaller than threshold B, for example: the threshold a may be 8mH and the threshold B may be 10mH.
And if the inductance value is less than or equal to the first preset inductance threshold value, obtaining a first inductance comparison result.
If the inductance value obtained at this time is 7mH, and at this time, the 7mH is smaller than 8mH of the threshold value a, it may be determined that the circuit board is a circuit board used in a 1P machine.
And if the inductance value is greater than the first preset inductance threshold value and less than or equal to the second preset inductance threshold value, obtaining a second inductance comparison result.
If the inductance value obtained at this time is 9mH, at this time, 8mH < -9mH < -10mH, the current circuit board can be determined to be a circuit board used in a 2P machine (the 2P machine is an air conditioner with the input power of about 1500W and the output power of about 4600W-5000W).
And if the inductance value is greater than a second preset inductance threshold value, obtaining a third inductance comparison result.
If the inductance value obtained at this time is 11mH, then 11mh >, 10mh, at this time, it can be determined that the current circuit board is a circuit board used in a 3P machine (the 3P machine is an air conditioner with an input power of about 2250W and an output power of about 6900W to 7500W).
It should be noted that, with the development of the air conditioner field, 4P machines and even 5P machines may appear in the future, so that a third preset inductance threshold value and even a fourth preset inductance threshold value may also be added, at this time, the third preset inductance threshold value is greater than the second preset inductance threshold value and is less than the fourth preset inductance threshold value, and at this time, the air conditioner corresponding to the current circuit board may be correspondingly determined according to the obtained actual inductance according to the 4 preset inductance threshold values. Meanwhile, it should be noted that the specific preset threshold provided in the present application does not constitute a limitation to the present application, and for example, 8mH and 10mH may be set accordingly according to specific situations. It should also be noted that, in the embodiments of the present application, a plurality of preset inductance thresholds may be set to meet specific situations.
203. And comparing the resistance value with a preset resistance threshold value to obtain a resistance comparison result.
In order to determine which type the air conditioner applied by the current circuit board belongs to more accurately, the embodiment of the application can also obtain the resistance value of the direct current resistor according to the obtained resistance value of the direct current resistor, and the resistance values of the direct current resistors of different circuit boards are different due to the fact that the circuit boards applied by the air conditioners of different types are different, so that after the resistance value is compared with the preset resistance threshold value and the resistance comparison result is further obtained, the result of determining the type of the air conditioner can be more accurate by combining the inductance comparison result of the steps.
In order to better understand the embodiment of the present application, in the embodiment of the present application, the comparing the resistance value with a preset resistance threshold value to obtain a resistance comparison result includes:
and comparing the resistance value with a first preset resistance threshold value and a second preset resistance threshold value, wherein the first resistance threshold value is smaller than the second preset resistance threshold value.
In order to obtain an accurate comparison result, two preset resistance thresholds may also be set here, for example a resistance threshold a and a resistance threshold B, where the resistance threshold a is smaller than the resistance threshold B, for example: the threshold resistance a may be 5000 ohms and the threshold resistance B may be 6000 ohms.
And if the resistance value is less than or equal to the first preset resistance threshold value, obtaining a first resistance comparison result.
At this time, if the obtained resistance value is 4000 ohms, 4000 ohms < resistance threshold value a5000 ohms can be obtained, and the circuit board can be determined to be a circuit board used in a 1P machine.
And if the resistance value is greater than the first preset resistance threshold value and less than or equal to the second preset resistance threshold value, obtaining a second resistance comparison result.
If the obtained resistance value is 5500 ohms, 5000 ohms <5500 ohms <6000 ohms can be obtained, and the circuit board can be determined to be a circuit board used in a 2P machine.
And if the resistance value is larger than the second resistance threshold value, obtaining a third resistance comparison result.
If the obtained resistance value of the resistor is 6500 ohm, 6500 ohm >6000 ohm can be obtained, and the circuit board can be determined to be a circuit board used in a 3P machine.
It should be noted that, with the development of the air conditioner field, 4P machines and even 5P machines still appear in the future, so a third preset resistance threshold value and even a fourth preset resistance threshold value may also be added, at this time, the third preset resistance threshold value is greater than the second preset resistance threshold value and is less than the fourth preset resistance threshold value, and at this time, the air conditioner corresponding to the current circuit board may be correspondingly determined according to the obtained actual resistance values and the 4 preset resistance threshold values. Meanwhile, it should be noted that the specific preset threshold provided in the present application does not constitute a limitation to the present application, and for example, 4000 ohms and 6000 ohms may be set according to specific situations. It should also be noted that, in the embodiments of the present application, a plurality of preset resistance thresholds may also be set to meet specific situations.
204. And adjusting the carrier frequency of the circuit board according to the inductance comparison result and the resistance comparison result.
In order to make the carrier frequency of the circuit board more accurate, the embodiment of the present application may combine two comparison results, an inductance comparison result and a resistance comparison result, to determine which air conditioner the current circuit board is specifically applied to, so as to reduce an error when determining the circuit board, for example: if the circuit board is judged only by obtaining the inductance comparison result, and the resistance comparison result is not referred to, only one judgment dimension is needed, and in order to improve the accuracy of judgment, judgment is needed according to the resistance comparison result.
In order to better implement the embodiments of the present application, in the embodiments of the present application, the inductance comparison result includes a first inductance comparison result, a second inductance comparison result, a third inductance comparison result, and an erroneous inductance comparison result, the resistance comparison result includes a first resistance comparison result, a second resistance comparison result, a third resistance comparison result, and an erroneous resistance comparison result, and the adjusting the carrier frequency of the circuit board according to the inductance comparison result and the resistance comparison result includes:
and if the resistance comparison result is the error resistance comparison result, adjusting the carrier frequency of the circuit board according to the inductance comparison result.
If the current air conditioner is related to a program for obtaining a resistance comparison result or corresponding hardware is damaged, namely the obtained resistance value is 0, the current air conditioner can directly judge the wrong resistance comparison result without comparing with a preset resistance threshold value, so that the condition that the field setting of the air conditioner is delayed due to the reason that the program error is similar to the fault can be avoided, and the carrier frequency can be adjusted only according to the inductance comparison result. For example: when the manual work can not be repaired in time and the air conditioner needs to leave the factory on time, the corresponding adjustment can be carried out through the scheme, and the content described in the embodiment is as follows: when the resistance comparison result is not referred to, an error may occur, for example, when the currently obtained inductance is 8mH, which is equal to the first inductance threshold, it may be determined that the current circuit board is applied to the 1P machine. However, the situation that the program is wrong or the corresponding equipment is damaged belongs to a special situation, the probability of the special situation is very low, if the air conditioner cannot leave a factory in time, the construction period or the delay or the shelving of a project can be caused, extra loss is caused, and the scheme can be used as a standby regulation scheme.
In order to better implement the embodiment of the present application, in the embodiment of the present application, if the resistance comparison result is the erroneous resistance comparison result, adjusting the carrier frequency of the circuit board according to the inductance comparison result includes:
and if the inductance comparison result is the first inductance comparison result, adjusting the carrier frequency of the circuit board to a first carrier frequency.
For example, when the first inductance comparison result is obtained, it may be determined that the current circuit board is applied in the 1P machine. If the first inductance comparison result is obtained, that is, it is determined that the current circuit board is applied to the 1P machine, and after the first resistance comparison result is obtained, it is also determined that the current circuit board is applied to the 1P machine, and after the double determination, it may be finally determined that the current circuit board is indeed applied to the 1P machine, and at this time, according to the power parameter (mentioned in the above embodiment, which is not described here again), which is related to the 1P machine, the carrier frequency of the circuit board may be adjusted, for example, to 50Hz.
And if the inductance comparison result is the second inductance comparison result, adjusting the carrier frequency of the circuit board to a second carrier frequency.
For example, when the second inductance comparison result is obtained, it may be determined that the current circuit board is applied in the 2P machine. If the second inductance comparison result is obtained, that is, it is determined that the current circuit board is applied to the 2P machine, and after the second resistance comparison result is obtained, it is also determined that the current circuit board is applied to the 2P machine, and after the double determination, it may be finally determined that the current circuit board is indeed applied to the 2P machine, and at this time, according to the power parameter (mentioned in the above embodiment, which is not described here again), which is related to the 2P machine, the carrier frequency of the circuit board may be adjusted, for example, to 60Hz.
And if the inductance comparison result is the third inductance comparison result, adjusting the circuit board carrier frequency to a third carrier frequency.
For example, when the third inductance comparison result is obtained, it may be determined that the current circuit board is applied in the 3P machine. If the third inductance comparison result is obtained, that is, it is determined that the current circuit board is applied to the 3P machine, and after the third resistance comparison result is obtained, it is also determined that the current circuit board is applied to the 3P machine, and after the double determination, it may be finally determined that the current circuit board is indeed applied to the 3P machine, and at this time, according to the power parameter (mentioned in the above embodiment, which is not described here again), which is related to the 3P machine, the carrier frequency of the circuit board may be adjusted, for example, to 70Hz.
And if the inductance comparison result is the error inductance comparison result, adjusting the carrier frequency of the circuit board according to the resistance comparison result.
If the current air conditioner is in a program related to obtaining the inductance comparison result or the corresponding hardware is damaged, the carrier frequency can be adjusted only according to the resistance comparison result. For example: when the manual work can not be repaired in time and the air conditioner needs to leave the factory on time, the corresponding adjustment can be carried out through the scheme, for example: when the inductance comparison result is not referred to, an error may occur, for example, when the currently obtained resistance value is 5000 ohms, which is equal to the first resistance threshold value, it may be determined that the current circuit board is applied to the 1P machine. The same program is wrong or corresponding equipment is damaged, the special condition belongs to the special condition, the probability of the special condition is also low, if the air conditioner cannot leave a factory in time, the construction period or the delay or the suspension of a project can be caused, extra loss is caused, and the scheme can be used as a standby regulation scheme.
