The invention is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It should be understood that the preferred embodiments are illustrative of the invention only and are not limiting upon the scope of the invention.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
In the following description, numerous details are set forth to provide a more thorough explanation of embodiments of the present invention, however, it will be apparent to one skilled in the art that embodiments of the present invention may be practiced without these specific details, and in other embodiments, well-known structures and devices are shown in block diagram form, rather than in detail, in order to avoid obscuring embodiments of the present invention.
It should be noted that, in the present invention, the video data and the audio data are processed by deep learning models, which can be selected from the prior art. The deep learning model is a machine learning algorithm, and a multilayer perceptron with a plurality of hidden layers is a deep learning structure. Deep learning forms a more abstract class or feature of high-level representation properties by combining low-level features to discover a distributed feature representation of the data. The deep learning model transforms the feature representation of the sample in the original space to a new feature space through layer-by-layer feature transformation, thereby facilitating classification or prediction. The deep learning model establishes a proper amount of neuron calculation nodes and a multilayer operation hierarchical structure through design, selects a proper input layer and a proper output layer, establishes a functional relation from input to output through learning and tuning of a network, can approach a real association relation as much as possible, and can realize the automation requirement on complex transaction processing by using a network model which is successfully trained.
In the invention, a deep learning model is mainly utilized to process two aspects of data, one is to carry out voice recognition on a sound signal in a passenger cabin so as to extract an air conditioner control instruction contained in voice, and the other is to carry out recognition on video data or image data in the passenger cabin so as to judge whether a sensitive target exists in the passenger cabin and determine the specific position of the sensitive target; those skilled in the art can select a suitable deep learning model from the prior art to process the data in the present invention without creative work according to the description of the present invention, for example, CNN (convolutional neural network model) -HMM (hidden markov model) or RNN (recurrent neural network) -HMM can be used to perform voice recognition of the sound signal, and for example, yolo (youonlook) target detection model or ssd (single Shot multi box detector) target detection model can be used to recognize the image data in the passenger compartment.
Fig. 1 is a schematic operating environment diagram of an integrated air conditioner control method according to an exemplary embodiment of the present invention, which illustrates a hardware environment to which the present invention is applied, and includes an execution end 101, a control end 102, a sensing end 103, and an interaction end 104, where the sensing end 103 includes a temperature sensor, a humidity sensor, a carbon dioxide/oxygen concentration detection sensor, and a vehicle-mounted altitude instrument, and these modules are mainly used to obtain some objective environmental data, such as temperature, humidity, carbon dioxide or oxygen concentration, altitude; the interaction terminal 104 is mainly used for acquiring passenger information and external information, wherein the passenger information includes physical and morphological characteristics and behavior characteristics, and the external information includes weather information and season information; the control end 102 is mainly used for integrating the information and sending the information to the execution end 101, and the execution end 101 controls the air conditioning system, the humidification and dehumidification system and the oxygenation system to work according to the information and a preset computer program, so that the purpose of air conditioning integrated control is achieved.
It is understood that some of the modules in the above hardware environment can be replaced by functional modules that are available in the existing smart car itself, for example, a camera recognition module, a voice recognition module, and a weather system in the existing cabin entertainment system can be used as the interactive end 104 of the present invention. The components of the hardware environment to which the present invention is applicable are not limited to the structure shown in fig. 1, and the present invention may also be applied to a third-party vehicle-mounted terminal or a network device, for example, the present invention may be operated on a remote server, and data acquisition and control instruction output may be realized through a network.
Air conditioner control based on environment recognition is the main direction of intelligent automobile development, and the existing intelligent automobile can only realize corresponding operation according to the instruction of a user and cannot actively make a control decision based on the environment change. For example, when a passenger in the vehicle is sleeping, the air conditioning amount of the air conditioner cannot be reduced autonomously by the vehicle, or the user is required to control the air conditioning system to work in a manual or voice interaction mode.
In addition, the existing air-conditioning control strategy is too rigid to perform targeted control according to the specific requirements of each passenger, for example, when a user sends a voice command for reducing the temperature, the existing control system can reduce the temperature of the air conditioner of the whole vehicle, and actually, the user may only want to reduce the temperature of the air conditioner nearby, while other passengers want to keep the higher temperature.
The problems noted above have general applicability in general air conditioning use scenarios. It can be seen that the existing air conditioner control strategy lacks an active decision function, and the control process is rigid, so that a targeted decision cannot be made according to the requirements of different passengers. To solve these problems, embodiments of the present invention respectively provide an integrated control method of an in-vehicle air conditioner, an integrated control apparatus of an in-vehicle air conditioner, an electronic device, a computer storage medium, and a vehicle, and will be described in detail below.
Fig. 2 is a flowchart illustrating an air conditioner integrated control method according to an exemplary embodiment of the present invention. The method can be applied to the hardware environment shown in fig. 1, and is specifically executed by the execution end 101 in the hardware environment. It should be understood that the method may also be applied to other exemplary hardware environments and specifically executed by devices in other implementation environments, and the embodiment does not limit the hardware environment to which the method is applied.

S202, obtaining environmental temperature and season information.
The ambient temperature may be collected by a temperature sensor, and the season information may be obtained by a weather system of the vehicle itself, or the current season may be determined by a date and current coordinates of the vehicle.
