As shown in fig. 4, in one embodiment, before step S301, the following steps S401 to S403 are included:
step S401, when the ambient temperature sensor normally operates, acquiring associated data and acquiring the ambient temperature of the position where the air conditioner external unit is located through the ambient temperature sensor, wherein the associated data comprises meteorological data and operating parameters of the air conditioner external unit.
In application, when the running state of the environment temperature sensor is monitored to be normal running, all relevant data possibly related to the real environment temperature of the position where the outdoor unit of the air conditioner is located, namely various meteorological data such as temperature, wind speed and weather state and various running parameters such as working mode, high voltage, low voltage and fan rotating speed are obtained, meanwhile, the real environment temperature of the position where the outdoor unit of the air conditioner is located is obtained through the environment temperature sensor, and the obtained real environment temperature is accurate. The ambient temperature sensor is a temperature sensor provided in the air conditioner outdoor unit, for example, the ambient temperature sensor 41 shown in fig. 1 or fig. 2.

In application, a machine learning method can be adopted to perform correlation analysis on all data acquired by history. The target related data related to the ambient temperature of the current location of the outdoor unit of the air conditioner should be data, of all related data, with a correlation with the ambient temperature greater than a preset threshold, for example, if the change of the related data has a large influence on the ambient temperature, it indicates that the correlation between the related data and the ambient temperature is high, otherwise, the correlation is low. The preset threshold value can be set by a user according to actual needs in a self-defined mode or by default set in a computer program run by the computing device in a preset mode.

and rejecting all related data acquired by history and abnormal data in all environmental temperatures.
In application, some abnormal data caused by accidental factors such as communication quality factors, extreme environment factors and other irresistible factors may exist in all data acquired in history, and the abnormal data needs to be removed so as to avoid causing bad interference on determination of target associated data and establishment of an association relation.

In application, the influence of the associated data on the ambient temperature of the current position of the outdoor unit of the air conditioner is embodied as the influence on the difference between the air temperature and the ambient temperature, so that target associated data influencing the difference in the remaining associated data can be determined by calculating the difference between all historical associated data and all ambient temperatures and analyzing the correlation between the remaining associated data except the image temperature and the difference, wherein the larger the influence on the difference, the higher the correlation is, and the lower the correlation is otherwise.

and step S603, when the working mode is the heating mode, acquiring the ambient temperature of the position where the air conditioner external unit is located according to the air temperature, the return air pressure and the second correlation relation.
In an application, in a specific example, by performing correlation analysis on the ambient temperature and the correlation data of the location where the external unit of the air conditioner is located, it is finally determined that the target correlation data related to the ambient temperature of the location where the external unit of the air conditioner is located includes air temperature, an operating mode of the external unit of the air conditioner, exhaust pressure and return pressure. The discharge pressure and the return pressure may be detected by pressure sensors provided in a discharge pipe and a return pipe of the air conditioning system, respectively, such as a discharge pressure sensor 11 and a return pressure sensor 12 shown in fig. 1 or 2.
In application, when the current air conditioner external unit is in different working modes, the incidence relation between the target incidence data and the environment temperature is different, that is, the mapping relation expressions for calculating the environment temperature according to the target incidence data are different.
In one embodiment, the expression of the first association relationship is as follows:
T＝t0+t1
t1＝f(Pc)＝a*Pc+b
where T represents an ambient temperature at a position where an outdoor unit of an air conditioner is located, T0 represents an air temperature, f (Pc) represents a function with respect to a discharge pressure Pc, and a and b are constants.
In one embodiment, the expression of the second association relationship is as follows:
T＝t0-t2
t2＝f(Pe)＝c*Pe+d
where T denotes an ambient temperature at a position where an air conditioner outdoor unit is located, T0 denotes an air temperature, f (Pe) denotes a function with respect to a return air pressure Pe, and c and d are constants.
In application, the functional expressions of the functions f (pc) and f (pe) can be obtained by a curve fitting method, and the constants a, b, c and d are constant terms in the functional expressions determined by the curve fitting method. As can be seen from the above expression, in the cooling mode, the temperature difference between the air temperature and the ambient temperature is a linear function related to the exhaust pressure, and the higher the exhaust pressure is, the larger the temperature difference is and the higher the ambient temperature is, otherwise, the smaller the temperature difference is and the lower the ambient temperature is; in the heating mode, the temperature difference between the air temperature and the ambient temperature is a linear function related to the return air pressure, and the higher the return air pressure is, the larger the temperature difference is and the lower the ambient temperature is, otherwise, the smaller the temperature difference is and the higher the ambient temperature is.
The ambient temperature detection method provided by the embodiment of the application can accurately acquire the ambient temperature according to the meteorological data, the operating parameters of the air-conditioner external unit and the pre-established incidence relation between the meteorological data and the operating parameters when the ambient temperature sensor arranged on the air-conditioner external unit breaks down, and can replace the ambient temperature sensor to realize the ambient temperature detection function so as to ensure the reliable operation and accurate control of the air conditioner and enable the air conditioner to continue to be normally used.
