In some embodiments, the target object may be identified by acquiring an image to be detected of the target area through a camera. The camera may be installed in an indoor unit of an air conditioner, or the camera may be installed at another position in the target area, where the installation position of the camera is not limited.
It should be noted that the camera can acquire an image to be detected according to a certain time period. The camera is connected with the controller in a communication mode, and the camera can send the acquired side image to be detected to the controller.

It can be understood that, based on the positioning information, it may be determined whether the target terminal is located in the target area, and then it may be determined whether the target object exists in the target area.
In case that the first input information of the user is received or the target object is detected in the target area, it may be further determined that there is a need to use the air conditioner in the target area.
In this case, the air conditioner needs to be turned on to meet the user's demand, and the air conditioner needs to be considered to reach the environmental conditions satisfied by the user as soon as possible in the formal use process, so the air conditioner needs a more sufficient and stable power supply. Therefore, the air conditioner can be controlled to be switched to be supplied with power through the wind-solar energy storage system and the commercial power at the same time.
In the embodiment, the air conditioner is automatically started after the ambient temperature of the target area is detected, and the power is supplied through the wind and light energy storage system, so that the ambient temperature can be improved on the premise of utilizing the wind and light energy storage system, and the user experience is improved.
After the fact that the user has the requirement for using the air conditioner is really determined, the limitation and instability of the electric quantity of the wind and light energy storage system are considered, the air conditioner is powered by the wind and light energy storage system and the mains supply at the same time, the air conditioner can be guaranteed to be supplied with sufficient and stable electric energy, the user requirement is better met, and the user experience is improved.
According to the control method of the air conditioner, provided by the embodiment of the invention, the air conditioner is automatically started to operate by detecting the ambient temperature of the target area, and the wind and light energy storage system is used for supplying power, so that the utilization rate of new energy is improved, and after the requirement of a user for using the air conditioner is determined, the wind and light energy storage system and the mains supply are used for supplying power at the same time, so that the utilization of the new energy is realized, and the sufficient and stable energy supply of the air conditioner is ensured.
In some embodiments, at step 110: in a case where the detected temperature of the target area is in the target zone, before determining the target frequency of the compressor of the air conditioner, the control method of the air conditioner of the embodiment of the present invention includes the following processes.
And judging whether the target object exists in the target area or not, and determining the running state of the air conditioner. And acquiring the detection temperature of the target area under the condition that the target area does not detect the target object or the air conditioner is in a closed state.
It is understood that the detection of the internal circuit of the air conditioner may be performed to determine whether the air conditioner is in an off state.
And further determining the detection temperature of the target area when the target object is not detected in the target area or the air conditioner is detected to be in a closed state.
In this embodiment, by detecting the target object in the target area or the off state of the air conditioner, it can be determined that the user has not turned on the air conditioner in this case, and the user cannot turn on the air conditioner automatically for a while, in this case, there is a scenario in which the air conditioner is turned on automatically in advance.
In the embodiment, by determining the scene, the air conditioner can be more intelligently started under the condition that the user feels no, so that the use experience of the user is improved.
In some embodiments, at step 130: after the air conditioner is controlled to be switched to be simultaneously powered by the wind-solar energy storage system and the commercial power, the control method of the air conditioner further comprises the following processes.
The mains voltage may be determined first, and the operating frequency of the compressor may be reduced to the first frequency when the mains voltage is less than the first preset value.
In this embodiment, the voltage condition of the commercial power for the air conditioner operation can be detected to distinguish the normal voltage condition from the under-voltage condition. Under the condition of normal voltage, the air conditioner provided by the embodiment of the invention operates at a normal frequency under a corresponding working mode.
Under the condition that the mains voltage is under-voltage, namely under the condition that the mains voltage is smaller than the first preset value, the air conditioner provided by the embodiment of the invention operates according to the condition that the frequency of the compressor is reduced to the first frequency, so that the power consumption of the system is reduced. For example, the first preset value may be 95% of the rated voltage of the air conditioner.
It can be understood that the commercial power voltage is low to a certain extent, the air conditioner current is large, and the air conditioner can carry out current protective frequency reduction. Under the condition that the current of the air conditioner is not reduced automatically, the frequency of the compressor of the air conditioner is reduced to the first frequency, so that the electric energy can be saved.
In some embodiments, the first frequency may be set as an empirical value, and in other embodiments, the first frequency may be set synthetically according to the generated power of the wind-solar energy storage system, and the specific setting manner of the first frequency is not limited herein.
In the embodiment, the frequency of the compressor of the air conditioner is reduced under the condition that the mains voltage is under-voltage, so that electric energy can be saved.
It will be appreciated that the compressor of the air conditioner may operate at different frequencies. When the compressors work according to different frequencies, the power of the compressors is different, and the power consumption of the compressors is different at the same time.
In the embodiment, because the power consumption of the compressor of the air conditioner accounts for a very large ratio, when the power consumption of the air conditioner and the power supply of wind and light energy storage are considered, the target frequency of the compressor of the air conditioner can be determined by combining the real-time stored power and the real-time generated power of the wind and light energy storage system. In this case, the wind-solar energy storage system can meet the requirement that the compressor of the air conditioner works according to the target frequency.
In some embodiments, determining the target frequency of the compressor of the air conditioner may include the following process.
The real-time storage electric quantity and the real-time generation power of the wind and light energy storage system can be determined firstly.
In some embodiments, the real-time storage capacity of the wind and photovoltaic energy storage system may be determined by receiving a value reported by a power management system of the storage battery pack.
The real-time power generation power of the wind-solar energy storage system can be confirmed through the received real-time power of the solar photovoltaic power generation equipment and the wind driven generator.
It should be noted that, when the real-time stored electricity amount is greater than or equal to the second preset value, the real-time generated power may be determined as the total power of the air conditioner, and then the target frequency may be determined based on the total power of the air conditioner.
If the maximum electric quantity stored by the wind and light energy storage system is W, the second preset value may be a × W, where a is a constant greater than 0.8 and less than or equal to 1. For example, a may be 1.
