Description

Operation control method and system of air conditioner compressor and storage medium
Technical Field
The invention relates to the technical field of air conditioners, in particular to an operation control method and system of an air conditioner compressor and a storage medium.
Background
In some areas, the power consumption is high during peak hours, so that the situation of insufficient power supply sometimes occurs. When the line is short of power, a plurality of household appliances are operated at the same time, and especially when a high-power appliance is operated, a line fault may occur. Some residents also adopt the mode that private generator and commercial power combine together to supply power for daily household appliances, but the generator power supply capacity is limited, if the load is too many, the power supply line is easy to overload, causes the circuit trip, influences other household appliances and uses, and has the potential safety hazard.
Accordingly, there is a need in the art for a new operation control method of an air conditioner compressor to solve the above-mentioned problems.
Disclosure of Invention
In order to solve the above problems in the prior art, that is, to solve the problem that the conventional air conditioner cannot be operated simultaneously with other electrical appliances under the condition of insufficient power supply, a first aspect of the present invention provides an operation control method for an air conditioner compressor, the operation control method including:
acquiring real-time current of the compressor under the condition of insufficient power;
comparing the real-time current with a preset current threshold;
and adjusting the frequency of the compressor in a step adjustment mode according to the comparison result.
The operation control method of the air conditioner compressor is suitable for the situation of insufficient line power supply, and the air conditioner is operated in a low-power state by adjusting the frequency of the compressor, so that the normal operation of other electrical appliances connected on a line is not influenced while the air conditioner is operated, and the adverse effect of insufficient power on a user is reduced. The frequency of the compressor is adjusted in a step adjustment mode, so that the running frequency of the compressor can be quickly and accurately adjusted to the target frequency, and the frequency modulation efficiency and the frequency modulation precision are improved.
With respect to the operation control method of the air conditioner compressor described above, in some possible embodiments, the step of "adjusting the frequency of the compressor in a stepwise adjustment manner" includes:
acquiring a frequency modulation speed for adjusting the frequency of the compressor;
adjusting the frequency of the compressor in a stepwise manner of adjusting the frequency modulation speed.
The frequency of the compressor is adjusted in a mode of adjusting the frequency modulation speed in a stepped mode, so that the frequency modulation efficiency and the frequency modulation precision can be improved. Specifically, in the frequency modulation process, when the real-time frequency is far away from the target frequency, the frequency is rapidly modulated to shorten the frequency modulation time, and when the real-time frequency is close to the target frequency, the frequency is slowly modulated to avoid the need of correction due to excessive adjustment, so that the frequency adjustment efficiency and precision can be improved by combining the speed and the speed.
The frequency modulation speed may be measured experimentally, and the obtained frequency modulation speed is a preset frequency modulation speed.
It should be noted that, during the frequency modulation, two situations may occur: the first is to turn down the operating frequency of the compressor, which is suitable for the process of insufficient power supply and power supply decline; the second is to increase the operating frequency of the compressor, which is suitable for the situation that the power supply is insufficient but tends to increase relative to the normal situation, and the performance of the compressor is improved by increasing the operating frequency of the compressor, but the operating frequency is still lower than the normal operating power even after the adjustment. Whether the frequency is adjusted to be high or low, the frequency modulation speed is reduced in a step mode in the process of adjusting from the real-time frequency to the target frequency.
With respect to the operation control method of the air conditioner compressor, in some possible embodiments, the preset current threshold is determined based on the real-time current.
It should be noted that the current threshold includes a plurality of preset current thresholds, and the process of determining the preset current threshold based on the real-time current is a process of selecting the most appropriate current threshold from the plurality of current thresholds, in other words, the process of determining the current threshold is also a process of selecting the current threshold, because the current thresholds are also under-supplied power, the under-supplied power is not necessarily the same at different times, the supplied power is deviated from the normal condition to a higher degree and is deviated from the normal condition to a lower degree, and the different current thresholds are selected for different power supply conditions, so that the performance of the air conditioner can be guaranteed to the maximum extent on the premise of guaranteeing the normal operation of other devices on the line.
With respect to the operation control method of the air conditioner compressor, in some possible embodiments, the determining of the preset current threshold includes:
acquiring a real-time voltage of the compressor;
calculating real-time power according to the real-time voltage, and calculating a ratio between the real-time power and rated power;
determining a current gear according to the ratio;
determining the preset current threshold according to the current gear,
and a preset mapping relation is formed between the current gear and the preset current threshold.
The current gear is determined by calculating the obtained power ratio, namely the influence of the current and the voltage on the frequency modulation result is simultaneously integrated, so that the determined target frequency can be more accurate. In addition, through gear division of the current, a proper current threshold value can be determined based on the selected current gear, and then the target frequency is determined based on the selected current threshold value, so that the accuracy of the target frequency can be improved.
It should be noted that the preset current threshold and the target frequency have a preset mapping relationship.
As to the operation control method of the air conditioner compressor, in some possible embodiments, the step of "obtaining the real-time voltage of the compressor" specifically includes:
and acquiring real-time voltage of the compressor while acquiring real-time current of the compressor.
The real-time voltage of the compressor is obtained while the real-time current of the compressor is obtained, so that the time required by data acquisition can be shortened, and the quick response of the compressor is realized.
It will be appreciated that the real-time voltage may also be acquired before or after the real-time current is acquired.
With respect to the operation control method of the air conditioner compressor, in some possible embodiments, the determining of the preset current threshold further includes:
after calculating the ratio between the real-time power and the rated power, comparing the ratio with a safety threshold; and if the ratio is larger than the safety threshold, determining the current gear according to the ratio.
It should be noted that the safety threshold is a minimum value at which the air conditioner can maintain a low-power operation state, and the ratio of the real-time power to the rated power should be greater than the safety threshold to start the air conditioner. For example, when the ratio of the real-time power to the rated power is lower than 0.7, the air conditioner cannot be started, and the safety threshold is 0.7.
The second aspect of the present invention also provides a computer-readable storage medium, which stores a computer program, wherein the computer program is executed by a processor to implement the operation control method of the air conditioner compressor according to any one of the above technical solutions.
The third aspect of the present invention further provides a control system, which comprises a memory and a processor, wherein the memory is suitable for storing a plurality of program codes, and the program codes are suitable for being loaded and executed by the processor to execute the operation control method of the air conditioner compressor in any one of the technical schemes.
The fourth aspect of the present invention further provides an operation control system of an air conditioner compressor, where the control system includes a program module, and the program module is configured to execute the operation control method of the air conditioner compressor according to any one of the foregoing technical solutions.
It can be understood by those skilled in the art that, for the control system and the operation control system provided by the present invention, since the operation control method in the foregoing technical solution can be implemented, all technical effects of the foregoing technical solution are achieved, and details are not described herein.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention.
Furthermore, in the following detailed description, numerous specific details are set forth in order to provide a better understanding of the present invention. It will be understood by those skilled in the art that the present invention may be practiced without some of these specific details.
Based on the problem that the prior air conditioner cannot give consideration to other electric equipment under the condition of insufficient power supply, the invention provides the operation control method of the air conditioner compressor, the operation control method of the air conditioner compressor is suitable for the condition of insufficient power supply of a line, and the air conditioner is operated in a low-power state by adjusting the frequency of the compressor, so that the normal operation of other electric appliances connected on the line can not be influenced while the air conditioner is operated, and the adverse influence of insufficient power on a user is reduced. The frequency of the compressor is adjusted in a step adjustment mode, so that the running frequency of the compressor can be quickly and accurately adjusted to the target frequency, and the frequency modulation efficiency and the frequency modulation precision are improved.
An operation control method provided by an embodiment of the present invention is described in detail below with reference to the accompanying drawings.
During electricity utilization, when power supply is insufficient, the household electrical appliance usually gives a prompt, for example, by means of an indicator lamp, a panel, a buzzer alarm, and the like. In the embodiment of the invention, the air conditioner is internally or externally provided with the low-voltage alarm device, the low-voltage alarm device continuously detects the voltage on the line at a certain frequency, for example, the line voltage is detected every s seconds, and when the voltage detected for t minutes is lower than the rated voltage U 0 And if so, determining that the power supply line of the air conditioner is in a state of insufficient power supply. Taking domestic civil rated voltage as 220V as an example, the low-voltage alarm device arranged in the air conditioner comprises a voltage detection device for detecting line voltage, the device detects the line voltage once every 2 seconds, and the detected voltage lasts for 3 minutesWhen the voltage is lower than the rated voltage 220V, the power supply line of the air conditioner is judged to be in a state of insufficient power supply, and the air conditioner can be controlled to enter a current limiting mode at the moment.
Specifically, the operation control method of the current limiting mode of the air conditioner includes the following steps.
And S10, acquiring the real-time current of the compressor under the condition of insufficient power.
Specifically, whether the line power supply is insufficient is judged through the low-voltage alarm device arranged in the air conditioner, and when the line power supply is judged to be insufficient, the real-time current of the air conditioner compressor is obtained and recorded.
And S20, comparing the real-time current with a preset current threshold value.
Specifically, the real-time current is the current acquired in step S10, and although the current threshold is preset, in the embodiment of the present invention, the current limiting process is divided into a plurality of different gears, each current gear has a corresponding current threshold, and an appropriate current threshold is selected according to the real-time current value, so as to improve the frequency modulation accuracy of the compressor. In the embodiment of the invention, the current of the compressor can be changed by adjusting the frequency of the compressor, and whether the frequency of the compressor is adjusted in place can be determined by monitoring the magnitude of the current.
The method for determining the current threshold comprises the following steps:
s201, acquiring real-time voltage of the compressor.
Specifically, the real-time voltage of the compressor is obtained while the real-time current of the compressor is obtained, so that the data obtaining time can be shortened, and the frequency modulation efficiency is further improved.
S202, calculating real-time power according to the real-time current and the real-time voltage, calculating a ratio between the real-time power and the rated power, and obtaining a power ratio S between the real-time power and the rated power.
It should be noted that, in order to ensure the normal operation of the electrical appliance, after the ratio between the real-time power and the rated power is calculated, the ratio needs to be compared with a preset safety threshold, and the safety threshold ensures that the air conditioner can operate normally and safely. The safety threshold in this embodiment is 0.7, that is, when the ratio between the calculated real-time power and the rated power is less than 0.7, it indicates that the air conditioner cannot normally operate in this state, and at this time, the air conditioner is directly controlled to shut down without adjusting the frequency of the air conditioner compressor. If the ratio is greater than the safety threshold, the subsequent procedure may be executed. It should be noted that the safety threshold is merely exemplary. The safety threshold is a positive number less than 1.
And S203, determining a current gear according to the ratio.
Specifically, the current gear is divided into three gears: and if the current gear is determined to be the L3 gear, the real-time current needs to be adjusted to a current value corresponding to the L gear.
The corresponding relationship of the three gears is as follows:
l1 gear: x 2 >S≥X 3
L2 gear: x 1 >S≥X 2
L3 gear: 1>S≥X 1
Wherein S represents the ratio of the real-time power to the rated power, namely S is the power ratio; x 1 、X 2 、X 3 Representing a current coefficient for determining a current threshold.
S204, determining a preset current threshold according to the current gear, wherein a preset mapping relation exists between the current gear and the preset current threshold.
Specifically, the current threshold of the L1 gear includes three: x 3 *I 0 +a、X 3 *I 0 +b、X 3 *I 0 (ii) a The current threshold for the L2 gear includes three: x 2 *I 0 +a、X 2 *I 0 +b、X 2 *I 0 (ii) a The current threshold for the L3 gear includes three: x 1 *I 0 +a、X 1 *I 0 +b、X 1 *I 0 . (ii) a Wherein a and b are preset node parameters, and a is greater than b and is a positive number.
And S205, comparing the real-time current with a preset current threshold.
Specifically, after the current threshold is determined, the real-time current is compared to the determined current threshold. Taking the current gear determined as the L3 gear as an example, the current threshold is determined as X 1 *I 0 +a、X 1 *I 0 +b、X 1 *I 0 . For example, the current threshold is determined as X 1 *I 0 +0.4、X 1 *I 0 +0.2、X 1 *I 0 . After the current threshold is determined according to the current gear, the obtained real-time current is compared with the determined preset current threshold.
And S30, adjusting the frequency of the compressor in a step adjustment mode according to the comparison result. Specifically, the step of adjusting the frequency of the compressor in a step adjustment manner includes:
s301, acquiring a frequency modulation speed for adjusting the frequency of the compressor. For example, the preset frequency modulation speed is 10Hz/s.
S302, adjusting the frequency of the compressor in a mode of adjusting the frequency modulation speed in a stepped mode. Specifically, when the real-time current I is greater than the threshold value X 1 *I 0 When +0.4, quickly reducing the frequency at the frequency modulation speed of 10 Hz/s; when the real-time current is larger than X 1 *I 0 +0.2 to X 1 *I 0 When +0.4, reducing frequency at medium speed with frequency modulation speed of 1 Hz/s; when the real-time current is less than or equal to X 1 *I 0 And when the frequency modulation speed is +0.2, the frequency is reduced at a speed of 1Hz/10s, so that the frequency modulation speed is gradually reduced in the process of approaching the current threshold, the step-type adjustment of the frequency modulation speed is realized until the real-time current is adjusted to the preset threshold and continuously runs, and the air conditioner can run in a low-power mode and can also run other electrical appliances. The real-time current can be accurately adjusted to the corresponding current threshold value, and the phenomenon that the adjustment is over and the call-back is caused is avoided, so that the frequency modulation efficiency and precision can be improved.
It should be noted that, the above embodiment is described by taking the current gear being divided into three gears as an example, and it is understood by those skilled in the art that the division of the current gear may be specifically set according to actual needs, for example, the current gear may be divided into 2 gears, 4 gears, and so on. In addition, the above embodiment is only exemplified by the L3 gearBy way of illustration, it will be understood by those skilled in the art that the current and frequency in gear L1 and gear L2 may be adjusted in the same manner. Furthermore, the data in the above embodiments include, but are not limited to, FM speed, a, b, S, U 0 、X 1 -X 3 The values are merely exemplary, and those skilled in the art can adjust the relevant values according to actual needs.
It should be noted that the operation control method provided by the embodiment of the present invention is also applicable to the case where the load in the line exceeds the standard, that is, the operation frequency of the air conditioner is reduced when the load in the line exceeds the standard, so that the power consumption of the air conditioner is reduced, and other electric devices are taken into consideration. In this case, whether the air conditioner enters the current-limiting operation mode can be judged by detecting the line current. Specifically, first every s 1 Detecting the bus current once per second when the duration is t 1 The measured current per minute is higher than the safe current i of the line 1 And if the load of the power supply line of the air conditioner exceeds the standard, the air conditioner can be controlled to enter a current limiting mode to operate. It should be noted that the current limiting mode of the air conditioner is realized by the control method in the above embodiment. In addition, the safety current i of the line 1 Should be less than the maximum current that the line can withstand.
It should be noted that the above embodiment is described by taking the adjustment of the compressor frequency as an example, and in some cases, a situation may occur that the power supply is gradually recovered but not recovered to a normal state, for example, the power supply is insufficient at the beginning and is only 70% of the rated voltage, but after the air conditioner is operated in a low power state for a period of time, the power supply capacity is recovered to 80% of the rated voltage, at this time, if the air conditioner is continuously operated at the previous frequency, part of the performance of the air conditioner may be sacrificed, at this time, there is a need to increase the operating frequency of the air conditioner to adaptively improve the performance of the air conditioner, a situation may occur that the frequency is adjusted up, and it can be understood that the frequency adjusting process is the same as the frequency adjusting process, that is, during the real-time current gradually approaches the preset current threshold, the frequency adjusting speed is all reduced in a stepwise manner.
