Embodiments of the present invention are described in further detail below in conjunction with fig. 1-5. The following examples are illustrative of the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, the present invention provides a control method of an outdoor unit of an air conditioner, which is applied to a control board of the air conditioner. The outdoor unit control method of the air conditioner comprises the following steps:
s1, acquiring an environment identification characteristic for identifying the outdoor environment parameter level.
S2, determining the corresponding working parameters of the outdoor unit according to the environment identification characteristics.
S3, generating an operation strategy for adjusting the operation of the outdoor unit according to the working parameters.
In an embodiment of the present invention, an outdoor unit includes: a sensor and an outdoor heat exchanger. The sensor is respectively connected with the outdoor heat exchanger and the control panel chip and is used for detecting outdoor environment parameters and determining grade information according to the outdoor environment parameters. Optionally, the sensor is configured as one or more of a temperature sensor, a humidity sensor, a radiation sensor and a wind speed sensor.
In the embodiment described above, the sensor is disposed at the air inlet of the outdoor heat exchanger to monitor the air inlet and obtain the outdoor environmental parameter through the air inlet. Optionally, a sensor is provided on the fan to monitor the actual rotational speed of the fan.
As shown in fig. 2, in an alternative embodiment, step S1 specifically includes:
s1.1, acquiring a first environment feature vector and a second environment feature vector of outdoor environment parameters, wherein the first environment feature vector points to instant feature information of the outdoor environment, and the second environment feature vector points to acquisition time length for acquiring the instant feature information.
S1.2, determining the environment identification feature according to the first environment feature vector and the second environment feature vector.
The first environmental characteristic vector at least comprises any one or a combination of a plurality of wind speed, temperature, humidity and solar radiation intensity of the environment where the outdoor unit is located.
Acquiring one or more of wind speed, temperature, humidity and solar radiation of an environment where an outdoor fan is positioned through a sensor arranged at an air inlet of an outdoor heat exchanger, and taking the data as a first environment characteristic vector; and at the same time, acquiring a time point corresponding to the first environmental feature vector, taking the set time period as a time period, acquiring the first environmental feature vector at the current time point every other time period, and generating the environmental identification feature of the outdoor fan by the first environmental feature vector and the corresponding time point corresponding to the acquired vector.
In another alternative embodiment, as shown in fig. 3, step S1 specifically includes:
s1.3, acquiring a geographical position parameter of the outdoor unit, and generating a first identification characteristic correction coefficient according to the geographical position parameter.
S1.4, updating the environment identification characteristic according to the first identification characteristic correction coefficient.
The method for acquiring the geographic position parameters of the outdoor unit comprises the steps that the control panel chip can determine the outdoor corresponding weather conditions according to the geographic position parameters, and the method comprises the following steps: temperature, humidity, radiation intensity, etc.
Taking the temperature as an example, if the outdoor unit obtains that the outdoor unit is located in beijing, the empirical value of the annual temperature interval of beijing city is between-8 ℃ and 34 ℃ according to the annual temperature change of beijing. Dividing the interval of-8 degrees celsius to 34 degrees celsius into three sets of temperature thresholds, a first temperature threshold: -8 degrees celsius (inclusive) to 10 degrees celsius (inclusive); second temperature threshold: 10 degrees celsius (inclusive) to 24 degrees celsius (inclusive); third temperature threshold: 24 degrees celsius (not included) to 34 degrees celsius (not included). The temperature is determined to be in which group of thresholds according to the temperature, wherein the temperature can be the real-time temperature acquired by a sensor or an empirical temperature value determined according to time.
If the temperature is in the first temperature threshold, taking the first correction coefficient as a first identification characteristic correction coefficient; if the temperature is in the second temperature threshold, taking the second correction coefficient as the first identification characteristic correction coefficient; and if the temperature is in the third temperature threshold value, taking the third correction coefficient as the first identification characteristic correction coefficient. Wherein the first correction coefficient, the second correction coefficient, and the third correction coefficient decrease in order.
And similarly, determining reasonable variation ranges of first environment feature vectors such as radiation intensity, humidity and the like through the geographic position, dividing the variation ranges into a plurality of groups of intervals, and taking a first identification feature correction coefficient according to the measured actual first environment feature vector or the interval where the empirical environment feature vector determined according to the geographic position is located.
When the air conditioner is started, the outdoor unit sends the position information of the outdoor unit to the cloud end, the cloud end determines the use province of the air conditioner after receiving the position information, and a time-by-time thermometer of the local province is sent to a control panel chip of the outdoor unit of the air conditioner. Alternatively, the time-by-time temperature table is taken from GB50736-2012 civil building heating ventilation and air conditioning design Specification. The environment identification features are extracted through a time-by-time thermometer.
Optionally, a local time-by-time thermometer is built in a control panel chip of the outdoor unit of the air conditioner according to the selling area of the air conditioner.
Further, the time-by-time thermometer is used as a template, and the time-by-time thermometer is updated according to the environment identification characteristics.
In the above embodiment, it is assumed that the geographic location of the outdoor unit is in a province with a smaller annual temperature difference such as the sea, the three-way, and the australia, and in the province with a smaller temperature difference, the on state of the air conditioner and the cooling capacity required to be provided are more stable, and in consideration of energy saving, the fourth correction coefficient is taken as the first identification characteristic correction coefficient, and the fourth correction coefficient is larger than the first correction coefficient.
In another alternative embodiment, as shown in fig. 4, step S1 specifically includes:
s1.5, acquiring an environment change function of the environment where the outdoor unit is located, and outputting at least the parameter change characteristics of the environment outside the inner chamber of the continuous acquisition time period by the environment change function.
S1.6, generating a second identification characteristic correction coefficient according to the environment change function.
S1.7, updating the environment identification characteristic according to the second identification characteristic correction coefficient.
Taking temperature as an example, the temperature is monitored and collected in real time through a temperature sensor arranged at an air inlet of the outdoor unit, and the collected temperature corresponds to the time for collecting the temperature, so that a temperature-time change function is obtained. Typically, the peak value of the function is the temperature value collected at noon. And a plurality of groups of temperature intervals are arranged in the control board chip, the vertex value of the determining function is positioned in a certain group of temperature intervals, and the second identification characteristic correction coefficient is determined according to the temperature intervals in which the vertex value of the determining function is positioned.
Specifically, 3 groups of temperature intervals are arranged in the control chip, and the temperature intervals are respectively the first temperature intervals: -30 degrees celsius (inclusive) to-10 degrees celsius (inclusive); a second temperature interval: -10 degrees celsius (inclusive) to 34 degrees celsius (inclusive); third temperature interval: 34 degrees celsius (not included) to 50 degrees celsius (not included). If the detected temperature value is in the first temperature interval or the third temperature interval, the first temperature correction coefficient is used as a second identification characteristic correction coefficient; and if the detected temperature value is in the second temperature interval, taking the second temperature correction coefficient as a second identification characteristic correction coefficient. Wherein the first temperature correction coefficient is greater than the second temperature correction coefficient.
When the temperature is in the second temperature interval, the air conditioner is in a normal working condition, and the second temperature correction coefficient can be used as a second identification characteristic correction coefficient. Wherein, the default value of the second temperature correction coefficient is 1. When the temperature is in the first temperature range or the third temperature range, which means that the outdoor unit is in a more extreme air temperature condition, the heating or cooling efficiency of the air conditioner is seriously affected in this case, and in order to ensure that the air conditioner can provide enough cooling capacity or heat as much as possible, the air speed of the outdoor unit needs to be increased, so that the first temperature correction coefficient needs to be set to be greater than the second temperature correction coefficient. For example, the first temperature correction coefficient is set to 1.1.
Optionally, according to the temperature-time variation function, the temperature variation in one day shows low, high and low variation trends, corresponding to the early, middle and late times in one day respectively. When the temperature is in the rising trend, judging that the time is transition from morning to noon, and taking a fourth temperature correction coefficient as a second identification characteristic correction coefficient; when the temperature is in the descending trend, judging that the time is the transition from noon to evening, and taking the fifth temperature correction coefficient as the second identification characteristic correction coefficient. The user's demand for cold or heat is typically greater in the afternoon than in the morning, and therefore will have a corresponding fifth temperature correction factor greater than the fourth temperature correction factor.
Taking radiation intensity as an example, the radiation intensity is monitored and collected in real time by a radiation sensor arranged at an air inlet of the outdoor unit, and the collected radiation intensity corresponds to the time for collecting the radiation intensity, so that a radiation intensity-time change function is obtained. The radiation intensity on the function exhibits a fluctuation of weak, strong, weak, extremely weak, which can correspond to early, middle, late, and night of the day. The control board chip is internally provided with a plurality of groups of radiation intensity intervals, the radiation intensity value is determined to be positioned in a certain group of radiation intensity intervals, and the second identification characteristic correction coefficient is determined according to the radiation intensity intervals in which the radiation intensity value is positioned.
Further, when the radiation intensity is in a trend from weak to strong, meaning that the time is a transition from morning to noon, taking the first radiation intensity correction coefficient as the second identification characteristic correction coefficient in the state; when the radiation intensity is in a trend of weakening from strong, the transition from noon to evening is meant, and the second radiation intensity correction coefficient is taken as the second identification characteristic correction coefficient in the state. And when the descending trend is still descending after the set time, judging that the time is night, and taking the third radiation intensity correction coefficient as the second identification characteristic correction coefficient in the state. The user's demand for cold or heat is typically stronger in the afternoon than in the morning, and therefore will have a corresponding second radiation intensity correction factor greater than the first radiation intensity correction factor. And at night, the user is in a rest state, so that excessive cold or heat is not easily provided, the third radiation intensity correction coefficient is properly reduced, and the third radiation intensity correction coefficient is smaller than the first radiation intensity correction coefficient.
In one embodiment provided by the present invention, step S2 specifically includes:
s2.1, acquiring a pre-stored fan rotating speed of an outdoor unit;
s2.2, if the fan rotating speed of the outdoor unit corresponding to the working parameters is smaller than the pre-stored fan rotating speed, generating an updated operation strategy according to the pre-stored fan rotating speed.
Specifically, in the invention, a judgment calculation formula is pre-stored on a control board chip in the outdoor unit, and the formula is as follows: y= (x-b) 2 。
Wherein x is an environmental identification feature; b is a first identification feature correction coefficient; y is the rotation speed of the outdoor fan.
Taking temperature as an example, x is an environment identification feature, and is formed by a first environment feature vector and a second environment feature vector. Specifically, the temperature value at each time point is substituted into x.
b is a first identifying characteristic correction factor, which is related to the geographic location parameter. And determining a reasonable range of temperature change according to annual temperature change corresponding to provinces, dividing the range into a plurality of groups, determining that the temperature is in a certain range at a certain moment according to the maximum value of x, and determining a first identification characteristic correction coefficient according to the corresponding range. As can be seen from the formula, when the value of x is close to the value of b, the fan rotation speed is small; when the difference between the value of x and the value of b is large, the rotating speed of the fan is large.
When the maximum value of x is in the second temperature interval, the operation season can be judged to be spring and autumn, the second correction coefficient is taken as the first identification characteristic correction coefficient, and optionally, the value of the second correction coefficient is taken as 10; when the maximum value of x is in the first temperature range, the maximum value of x can be judged to be in winter, the heat required by the air conditioner is more difficult to obtain due to lower winter temperature, and the wind speed needs to be increased more than that in spring and autumn to increase the heat exchange efficiency of the outdoor unit, so that the first correction coefficient is taken as the first identification characteristic correction coefficient, and the first correction coefficient is larger than the second correction coefficient. When the maximum value of x is in the third temperature interval, it can be judged that the air conditioner is summer at this time, and because the temperature in summer is higher, the required cold capacity of the air conditioner is more difficult to obtain, and more wind speeds are required to be increased than those in spring and autumn to increase the heat exchange efficiency of the outdoor unit, so that the third correction coefficient is taken as the first identification characteristic correction coefficient, and the third correction coefficient is smaller than the second correction coefficient.
Further, since the temperature interval is an empirical temperature interval in which the external unit of the air conditioner is located, there may be extreme high or low temperature conditions such that the measured temperature is not in any one set of temperature intervals. In this case, the outdoor fan rotation speed is adjusted to a maximum value by default.
In the embodiment described above, the calculation formula pre-stored on the control board chip may also be: y=a (x-b) 2 。
Wherein A is a second identification feature correction coefficient.
A is a second identification characteristic correction coefficient which is selected according to a change function of environmental parameters of the outdoor environment. Because the user has certain preference on the demand of cold or heat, the afternoon is generally stronger than the morning, and the time transition can be judged according to the change trend of the change function, so that the time period is judged and the second identification characteristic correction coefficient is selected. And when the temperature is at a relatively low temperature and is continuously set for a period of time, meaning that the period of time is night, taking the sixth temperature correction coefficient as the second identification characteristic coefficient, and taking the sixth temperature correction coefficient as the second identification characteristic coefficient, wherein the sixth temperature correction coefficient is smaller than the fourth temperature correction coefficient, the user takes rest at night and is not easy to provide excessive cold or heat.
In the above embodiment, the calculation formula pre-stored on the control board chip can also be：Y＝A(x-b) 2 +c。
Wherein c is the lowest rotating speed value of the fan.
