CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Patent Application No. PCT/CN2013/084387, filed on Sep. 27, 2013, which claims priority to Chinese Patent Application No. 201310185748.9, filed on May 17, 2013, both of which are hereby incorporated by reference in their entireties. 
    
    
     TECHNICAL FIELD 
     The present application relates to Internet technologies, and in particular, to intelligently controlling a device. 
     BACKGROUND 
     In daily life, intelligently controlling of an appliance (hereinafter referred to as “device”), such as a refrigerator, a washing machine, and a television set, can effectively reduce manual operation and improve usage experience of such device. For example, after a user sets a temperature range on a refrigerator, the refrigerator, in a running process, can intelligently detect a temperature and adjust the temperature to be within the temperature range. In this way, the user does not need to perform manual control, and therefore usage experience of the refrigerator is effectively improved. For another example, a user may set a running time of a washing machine at an off-peak time (usually at night), so that the washing machine uses the electricity at the off-peak rate. In this way, the user does not need to manually control the running of the washing machine during the off-peak time, and therefore usage experience of the washing machine is effectively improved. 
     Although the foregoing appliances or devices are intelligent, it is still required that a user performs related intelligent control. These devices are generally equipped with an intelligent chip, a display screen, and complex keys, requiring a user to have relatively high intelligent control skills, causing great inconvenience to a user at the time of performing the intelligent control and low utilization of the intelligent features.

     The above method may further include sending a software upgrade request which carries the identity information of the controlling device and version information of the device control program to the cloud server; receiving an upgrade packet of the device control program, wherein the upgrade packet of the device control program is sent by the cloud server after the cloud server determines that the device control program installed in the controlling device is not the latest version; and upgrading the device control program by using the upgrade packet. 
     The above method may further include receiving a connection establishment request from the interaction device; and sending a connection completion response to the interaction device so as to establish a connection between the controlling device and the interaction device. 
     In the above method, acquiring the parameter information of the controlled device may include sending a parameter information query to the controlled device; and receiving the parameter information of the controlled device from the controlled device in response to the parameter information query. 
     In the above method, converting the GUI into a data stream may include encoding the GUI into an encoded video data stream; and sending the data stream to an interaction device for displaying the GUI and the parameter information on the interaction device may include sending the encoded video data stream to the interaction device, so that the interaction device decodes the encoded video data stream, and renders the decoded video data stream into the GUI for displaying on the interaction device. 
     In a second aspect of the application, a controlling device is provided. The controlling device includes: a first connection interface for connecting to a controlled device; a second connection interface for connecting to an interaction device; a memory unit for storing program codes; and at least one processor, executing program codes stored in the memory unit. The first connection interface is configured to receive parameter information of the controlled device, wherein the parameter information reflects a current running state of the controlled device. The processor is configured to generate a graphical user interface (GUI) which integrates the parameter information, and convert the GUI into a data stream. The second connection interface is configured to send the data stream to the interaction device for displaying the GUI and the parameter information on the interaction device, and to receive a signal from the interaction device, wherein the signal is generated based on an input by a user on the interaction device for performing a control operation on the controlled device.

     DESCRIPTION OF EMBODIMENTS 
     The following clearly describes the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application. 
     Embodiments of the present application provide a method, an apparatus, and a system for intelligently controlling a device. Intelligently controlling of the device can be performed simply, conveniently, and fast. The following describes each of the embodiments in detail. 
       FIG. 1  is a flowchart of a method for intelligently controlling a device according to an embodiment of the present application. In order to implement intelligent control on a controlled device and provide a user-friendly graphical interaction interface, the embodiment of the present application introduces two types of devices, an interaction device and a controlling device. It should be noted that in the embodiment of the present application, the controlled device may be a common intelligent device or may also be an ordinary non-intelligent device (such as an ordinary non-intelligent refrigerator, a non-intelligent washing machine, or a non-intelligent television). When the controlled device is an ordinary non-intelligent device, the controlled device is not only integrated with a basic function actuator, but also should be integrated with an interface capable of communicating and interacting with the controlling device, such as, a standard universal serial bus (USB) interface. The controlling device may be a fixed or portable intelligent terminal. The controlling device not only needs to have an interface (such as a USB interface) for communicating and interacting with the controlled device, but also needs to have a capability of communicating and interacting with the interaction device. For example, the controlling device and the interaction device can access a same local area network or home network through Wi-Fi, so that the controlling device can communicate and interact with the interaction device through Wi-Fi. The interaction device may also be a portable intelligent terminal having a Wi-Fi capability, such as a mobile phone, a tablet computer, a personal computer (PC), or another mobile Internet device (MID), which is not limited in the embodiment of the present application. 
     As shown in  FIG. 1 , the method for intelligently controlling a device disclosed in the embodiment of the present application may include the following steps. 
       101 : A controlling device acquires parameter information of a controlled device in a current state, where the parameter information reflects a current running state of the controlled device. 
     In an embodiment, after the controlling device and the controlled device establish a connection through a standard USB interface, the controlling device may send a parameter information query to the controlled device. The controlled device sends the parameter information of the controlled device in the current state to the controlling device in response to the parameter information query. 
     In another embodiment, after the controlling device and the controlled device establish a connection through a standard USB interface, the controlled device may also proactively send the parameter information of the controlled device in the current state to the controlling device, manners of which are not limited in the embodiment of the present application. 
     In the embodiment of the present application, the parameter information of the controlled device in the current state is generally related to a type of the controlled device. For example, if the controlled device is a refrigerator, the parameter information of the controlled device in the current state may include a temperature, a refrigeration mode, a lighting mode of the refrigerator in a current running state, even types or quantities of food in the refrigerator, or the like. For another example, if the controlled device is a washing machine, the parameter information of the controlled device in the current state may include a set washing time, a washing mode (such as standard washing or quick washing) of the washing machine in a current running state, or the like. For still another example, if the controlled device is a television, the parameter information of the controlled device in the current state may include a set startup time, a default play channel, a voice volume, of the television in a current running state, or the like. 
       102 : The controlling device generates a graphical interaction interface including the parameter information of the controlled device in the current state. 
     In an embodiment, the controlling device may encapsulate the parameter information of the controlled device in the current state onto a graphical interaction interface, so as to generate the graphical interaction interface including the parameter information of the controlled device in the current state. 
       103 : The controlling device sends the graphical interaction interface in a form of a data stream to an interaction device for display. 
     In an embodiment, the controlling device may encode the graphical interaction interface into a video stream, and send the video stream to the interaction device. The interaction device decodes the video stream and renders the decoded video stream into the graphical interaction interface including the parameter information of the controlled device in the current state. 
       104 : The controlling device receives an input event sent by the interaction device, where the input event is triggered by a user based on the parameter information displayed on the graphical interaction interface of the interaction device; and parses the input event to obtain a control instruction corresponding to the parameter information included in the graphical interaction interface. 
     In the embodiment of the present invention, the controlling device may convert the input event into an input event matching with the graphical interaction interface generated by the controlling device, and parse the input event obtained through conversion to obtain the control instruction corresponding to the parameter information included in the graphical interaction interface. 
     For example, if the input event sent by the interaction device and received by the controlling device is triggered (such as, triggered through a gesture) by a user based on a temperature parameter that is of a refrigerator in a current state and included in the graphical interaction interface, the controlling device may parse the input event (that is, the gesture), so as to obtain a control instruction corresponding to the temperature parameter that is of the refrigerator in the current state and included in the graphical interaction interface. 
       105 : The controlling device sends the control instruction to the controlled device, so that the controlled device performs, in response to the control instruction, a control operation corresponding to the current running state of the controlled device. 
     The performing a control operation corresponding to the current running state of the controlled device includes performing an adjustment corresponding to the parameter information included in the graphical interaction interface. 
     For example, if the controlling device obtains, in the foregoing step  104 , the control instruction corresponding to the temperature parameter that is of the refrigerator in the current state and included in the graphical interaction interface, the controlling device may send the control instruction to the controlled device, so that the controlled device performs, in response to the control instruction, an adjustment (such as increase or decrease) of the temperature parameter that is of the refrigerator in the current state and included in the graphical interaction interface, so as to implement intelligent control on the temperature of the refrigerator in the current state. 
     For another example, if the controlling device obtains, in the foregoing step  104 , a control instruction corresponding to a set washing time that is of a washing machine in a current state and included in the graphical user interface, the controlling device may send the control instruction to the controlled device, so that the controlled device performs, in response to the control instruction, an adjustment (such as postponing or bringing forward the washing time) of the set washing time that is of the washing machine in the current state and included in the graphical interaction interface, so as to implement intelligent control on the set washing time of the washing machine in the current state. 
     By implementing the method described in  FIG. 1 , a user does not need to perform intelligent control on a controlled device by using an intelligent chip, a display screen, and/or complex keys integrated in the controlled device. The user can perform intelligent control on the controlled device by triggering, on an interaction device, a gesture instruction corresponding to parameter information included in a graphical interaction interface displayed on the interaction device. In this way, intelligent control on the controlled device can be performed simply, conveniently, and fast. 
     In addition, by implementing the method described in  FIG. 1 , the controlled device only needs to have a basic function actuator and does not need to be integrated with an intelligent chip, a display screen, and complex keys. In this way, the user is allowed to have a relatively low intelligent control technology threshold, which significantly reduces a barrier to a user performing intelligent control, increases actual utilization of the controlled device, and benefits promotion and popularization of the controlled device. 
     Further, by implementing the method described in  FIG. 1 , the user can trigger, by using the interaction device, a controlled terminal to perform an intelligent operation at a fixed time and independently, so that the user no longer relies on the controlled device, thus the present application has good adaptability. 
       FIG. 2  is a schematic diagram of a network architecture for intelligently controlling a device according to an embodiment of the present application. In the network architecture shown in  FIG. 2 , a controlling device can establish a communication connection to an interaction device through a network connection (which includes but is not limited to a wireless connection or a wired connection, such as, Wi-Fi). For example, the controlling device and the interaction device may each access, through Wi-Fi, a local area network where a wireless router is located, so that the controlling device can establish a communication connection to the interaction device through a wireless network connection. In the network architecture shown in  FIG. 2 , the controlling device establishes a connection to a controlled device (such as, a refrigerator) through a USB interface. As a control center for intelligently controlling a device, the controlling device may have an intelligent operating system such as Android™, and a device control service program for performing device control can run on the intelligent operating system, so as to perform the method for intelligently controlling a device disclosed in the embodiment of the present application. 
       FIG. 3  is a flowchart of another method for intelligently controlling a device based on the network architecture shown in  FIG. 2  according to an embodiment of the present application. As shown in  FIG. 3 , the method for intelligently controlling a device may include the following steps. 
       301 : After establishing a connection to a controlled device (such as, a refrigerator) through a USB interface, a controlling device sends a parameter information query to the controlled device through the USB interface. 
       302 : The controlled device queries parameter information of the controlled device in a current state in response to the parameter information query sent by the controlling device. 
     The parameter information query is used for instructing the controlled device to query the parameter information of the controlled device in the current state. 
     For example, if the controlled device is a refrigerator, the parameter information of the controlled device in the current state may include a temperature parameter, a refrigeration mode parameter, a lighting mode parameter of the refrigerator in the current state, even types or quantities of food in the refrigerator, or the like. 
       303 : After packaging the parameter information of the controlled device in the current state, the controlled device sends the packaged parameter information to the controlling device through the standard USB interface. 
       304 : The controlling device receives the parameter information of the controlled device in the current state which is sent by the controlled device, and generates a graphical interaction interface including the parameter information of the controlled device in the current state. 
       305 : The controlling device encodes the graphical interaction interface including the parameter information of the controlled device in the current state into a video stream, and sends the video stream to an interaction device through Wi-Fi. 
       306 : After receiving the video stream of the graphical interaction interface sent by the controlling device, the interaction device decodes the video stream, renders the decoded video stream into the graphical interaction interface including the parameter information of the controlled device in the current state, where the graphical interaction interface is displayed on a display unit (such as a screen) of the interaction device. 
       307 : The interaction device captures a touch operation, which is performed by a user based on the parameter information included in the graphical interaction interface. 
       308 : The interaction device converts the captured touch operation, which is performed by the user based on the parameter information included in the graphical interaction interface, into a screen coordinate input event, and encodes the screen coordinate input event into a gesture triggered by the user based on the parameter information included in the graphical interaction interface. 
     Content of the gesture triggered by the user based on the parameter information included in the graphical interaction interface may include attributes such as a touch operation type (such as, tap or flick), a touch operation area (including a touch operation start point and end point), a touch operation time, and acceleration direction. 
       309 : The interaction device sends the gesture triggered by the user based on the parameter information included in the graphical interaction interface to the controlling device through Wi-Fi. 
       310 : After receiving the gesture which is triggered by the user based on the parameter information included in the graphical interaction interface and is sent by the interaction device, the controlling device parses the gesture to obtain attributes included in the gesture, and then identifies, according to the attributes included in the gesture, a control instruction corresponding to the parameter information included in the graphical interaction interface. 
     For example, the controlling device may determine, according to a touch operation area (including a touch operation start point and end point) attribute included in the content of the gesture, parameter information included in the graphical interaction interface included in the touch operation area, namely, parameter information which the user needs to control; further, the controlling device may also determine, according to an acceleration direction attribute included in the content of the gesture, a control type (such as increasing, decreasing, or changing a mode) of the parameter information which the user needs to control, so as to obtain a control instruction corresponding to the parameter information included in the graphical interaction interface. 
     In the embodiment of the present invention, through the foregoing steps  307  to  308 , the objective, which is described in the foregoing embodiment, of obtaining a gesture triggered by the user based on the parameter information included in the graphical interaction interface can be achieved, while through the foregoing step  310 , the objective, which is described in the foregoing embodiment, of parsing the gesture to obtain a control instruction corresponding to the parameter information included in the graphical interaction interface can be achieved. 
       311 : The controlling device sends the control instruction triggered by the user based on the parameter information included in the graphical interaction interface to the controlled device through the USB interface. 
       312 : The controlled device performs, in response to the control instruction, an adjustment corresponding to the parameter information included in the graphical interaction interface, so as to implement intelligent control on the controlled device. 
     In the embodiment of the present application, by running a device control service program on an intelligent operating system, a controlling device can perform the method for intelligently controlling a device described in  FIG. 3 . By implementing the method described in  FIG. 3 , a user does not need to perform related intelligent control on a controlled device by using an intelligent chip, a display screen, and/or complex keys that are integrated in the controlled device, and the user can perform intelligent control on the controlled device by triggering, on an interaction device, a gesture instruction corresponding to parameter information included in a graphical interactive interface displayed on the interaction device. In this way, intelligent control on the controlled device can be performed simply, conveniently, and fast. 
     In addition, by implementing the method described in  FIG. 3 , the controlled device only needs to have a basic function actuator and does not need to be integrated with an intelligent chip, a display screen, and complex keys. In this way, the user is allowed to have a relatively low intelligent control technology threshold, which greatly reduces a barrier to a user performing intelligent control, increases actual utilization of the controlled device, and benefits promotion and popularization of the controlled device. 
     Further, by implementing the method described in  FIG. 3 , the user can trigger, by using the interaction device, a controlled terminal to perform an intelligent operation at a fixed time and independently, so that the user no longer relies on the controlled device, thus the present application has good adaptability. 
     As described in the foregoing embodiment, a controlling device can perform the method for intelligently controlling a device described in  FIG. 3  by running a device control service program on an intelligent operating system. Correspondingly, an embodiment of the present application further discloses a network architecture for upgrading a program. By using the network architecture for upgrading a program, a controlling device can download a device control service program from a cloud server and subsequently the controlling device can run the device control service program on an intelligent operating system, so as to perform the method for intelligently controlling a device described in  FIG. 3 .

The controlling device accesses, preferably through a wireless manner (such as, Wi-Fi), a local area network where the wireless router is located, and the wireless router connects to the cloud server through the Internet, so as to establish a connection between the controlling device and the cloud server. In addition, the controlling device also establishes a connection to the controlled device (such as, a refrigerator) through a USB interface. 
     A flowchart of a method for downloading a device control service program to a controlling device by using the network architecture of  FIG. 4  is shown in  FIG. 5 , and the method includes the following steps. 
       501 : A controlling device sends a type acquiring instruction to a controlled device. 
     The type acquiring instruction is used for instructing the controlled device to acquire type information of the controlled device. 
       502 : The controlled device sends the type information of the controlled device to the controlling device in response to the type acquiring instruction. 
     The type information of the controlled device may include information such as a device type, model information, or a device manufacturer of the controlled device. 
       503 : The controlling device sends identity information of the controlling device and the type information of the controlled device to a cloud server. 
       504 : After authenticating the identity information of the controlling device to be valid, the cloud server sends, to the controlling device, a device control service program matching with the type information of the controlled device. 
     In an embodiment, the cloud server may send, to the controlling device in a manner of a packet, the device control service program matching with the type information of the controlled device. 
     In an embodiment, after authenticating the identity information of the controlling device to be invalid, the cloud server may send an identity information authentication error message to the controlling device. 
       505 : The controlling device controls the device control service program matching with the type information of the controlled device to run, so as to perform the method for intelligently controlling a device described in  FIG. 3 . 
     In an embodiment, after receiving the device control service program which matches with the type information of the controlled device and is sent by the cloud server, the controlling device may further install the device control service program matching with the type information of the controlled device. 
     By implementing the method described in  FIG. 5 , a controlling device can download a device control service program from a cloud server in a network architecture for upgrading a program as shown in  FIG. 4 , and can perform the method for intelligently controlling a device described in  FIG. 3  by running the device control service program on an intelligent operating system. As a consequence, a user does not need to perform related intelligent control on a controlled device by using an intelligent chip, a display screen, and/or complex keys integrated in the controlled device, and can perform intelligent control on the controlled device by triggering, on an interaction device, a gesture instruction corresponding to parameter information included in a graphical interaction interface displayed on the interaction device. In this way, intelligent control on the controlled device can be performed simply, conveniently, and fast. 
     In addition, the controlled device only needs to have a basic function actuator, and does not need to be integrated with an intelligent chip, a display screen, and complex keys. In this way, the user is allowed to have a relatively low intelligent control technology threshold, which greatly reduces a barrier to a user performing intelligent control, increases actual utilization of the controlled device, and benefits promotion and popularization of the controlled device. 
     Further, the user can trigger, by using the interaction device, a controlled terminal to perform an intelligent operation at a fixed time and independently, so that the user no longer relies on the controlled device, thus the present application has good adaptability. 
     In an embodiment, before the controlling device downloads the device control service program from the cloud server in the network architecture for upgrading a program shown in  FIG. 4 , the controlling device may further first identify the controlled device by controlling a device identification service program to run After identifying the controlled device, the controlling device may start to perform the method described in  FIG. 5 , thereby implementing the downloading of the device control service program matching with the type information of the controlled device from the cloud server in the network architecture for upgrading a program shown in  FIG. 4 . 
     Correspondingly, an embodiment of the present application further discloses a method for updating a device identification service program to a controlling device by using the network architecture for upgrading a program shown in  FIG. 4 . A flowchart of the method is shown in  FIG. 6 , and the method includes the following steps. 
       601 : A controlling device sends a software upgrade request which carries identity information of the controlling device and version information of a device identification service program to a cloud server. 
       602 : After authenticating the identity information of the controlling device to be valid, the cloud server sends, to the controlling device, an upgrade packet of the device identification service program matching with the version information of the device identification service program. 
     In the embodiment of the present application, after the cloud server determines through authentication that the identity information of the controlling device is valid, the cloud server may further determine whether an upgrade packet of the device identification service program matching with the version information of the device identification service program is stored. If the upgrade packet of the device identification service program matching with the version information of the device identification service program is stored, the cloud server further sends, to the controlling device, the upgrade packet of the device identification service program matching with the version information of the device identification service program. If the upgrade packet of the device identification service program matching with the version information of the device identification service program is not stored, the cloud server determines that the device identification service program of the controlling device is of the latest version. In this case, the cloud server may also send, to the controlling device, a packet of the device identification service program matching with the version information of the device identification service program, as an upgrade packet of the device identification service program matching with the version information of the device identification service program.

     In an embodiment, before a controlling device sends, to an interaction device, a graphical interaction interface which includes parameter information of a controlled device in a current state and is in a form of a data stream for display, the controlling device and the controlled device further need to establish a communication connection.

While interaction device  1  may simultaneously establish a communication connection to one or more controlling devices of controlling device  1  to controlling device n through a wireless network (such as, Wi-Fi), interaction device  2  may also simultaneously establish a communication connection to one or more controlling devices from controlling device  1  to controlling device n through Wi-Fi, . . . , the rest can be deduced by analogy, and interaction device n may also simultaneously establish a communication connection to one or more controlling devices of controlling device  1  to controlling device n through Wi-Fi.

Therefore, the controlling devices, the controlled devices, and the interaction devices can freely form a system for intelligently controlling a device, and a user can perform flexible and diversified intelligent control on a same controlled device or different controlled devices by using different interaction devices.
