Description

METHOD, APPARATUS, AND SYSTEM FOR INTELLIGENTLY CONTROLLING DEVICE, AND PLUG-AND-PLAY DEVICE TECHNICAL FIELD [0001] The present invention relates to the field of Internet technologies, and in particular, to a 5 method, an apparatus, and a system for intelligently controlling a device, and a plug-and-play device. BACKGROUND [0002] In daily life, intelligent control on devices such as refrigerators, washing machines, and televisions can effectively reduce manual operations of a user and improve usage experience of the 10 user for such devices. For example, after a user performs control on a temperature range of a refrigerator, the refrigerator in a running process can intelligently detect a temperature and control the temperature within the temperature range. In this way, the user does not need to perform manual control again subsequently, and therefore usage experience of the user for the refrigerator is effectively improved. For another example, a user may control a period of runtime of a washing 15 machine, so that the washing machine can intelligently run by using a night peak-valley electricity period of time. In this way, the user does not need to manually control the running of the washing machine during the night peak-valley electricity period of time, and therefore usage experience of the user for the washing machine is effectively improved. [0003] Although the foregoing device is intelligent, it is still required as a precondition that a 20 user performs related intelligent control. However, the foregoing device is generally integrated with an intelligent chip, a display screen, and complex keys. This requires a user to have a relatively high intelligent control technology threshold, which therefore causes a great barrier to a user at the time of performing intelligent control and low actual utilization of the foregoing device, which is bad for promotion and popularization. 25 SUMMARY [0004] Embodiments of the present invention disclose a method, an apparatus, and a system for intelligently controlling a device, and a plug-and-play device, which can perform intelligent control 1 on a device simply, conveniently, and fast.

DESCRIPTION OF EMBODIMENTS [0049] The following clearly and completely describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the 5 embodiments of the present invention. Apparently, the described embodiments are merely a part rather than all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention. [0050] Embodiments of the present invention disclose a method, an apparatus, and a system for 10 intelligently controlling a device, which can perform intelligent control on a device simply, conveniently, and fast. The following describes each of the embodiments in detail. [0051] Referring to FIG. 1, FIG. 1 is a flowchart of a method for intelligently controlling a device according to an embodiment of the present invention. In the method for intelligently controlling a device described in FIG. 1, in order to implement intelligent control on a controlled 15 device and provide a user-friendly graphical interaction interface, the embodiment of the present invention introduces two types of devices, that is, an interaction device and a controlling device, based on the controlled device. It should be noted that in the embodiment of the present invention, 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 20 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 (Universal Serial BUS, USB) interface. The controlling device may be a fixed or portable intelligent terminal. The controlling device not only needs to have 25 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 30 intelligent terminal having a Wi-Fi capability, such as a mobile phone, a tablet computer, a PC, or another mobile Internet device (Mobile Internet Devices, MID), which is not limited in the embodiment of the present invention. [0052] As shown in FIG. 1, the method for intelligently controlling a device disclosed in the 15 embodiment of the present invention may include the following steps. [0053] 101: A controlling device acquires parameter information of a controlled device in a current state, where the parameter information is used for reflecting a current running state of the controlled device. 5 [0054] 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 instruction to the controlled device, so that the controlled device can send the parameter information of the controlled device in the current state to the controlling device in response to the parameter information query instruction. 10 [0055] 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, which is not limited in the embodiment of the present invention. [0056] In the embodiment of the present invention, the parameter information of the controlled 15 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 reflect a temperature, a refrigeration mode, a light working mode of the refrigerator in a current running state, even a type or a quantity 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 20 device in the current state may reflect a set washing time, a washing mode (such as standard washing or quick washing),, or the like of the washing machine in a current running state. For still another example, if the controlled device is a television, the parameter information of the controlled device in the current state may reflect a set startup time, a default play channel, a voice volume, or the like of the television in a current running state. 25 [0057] 102: The controlling device generates a graphical interaction interface including the parameter information of the controlled device in the current state. [0058] 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 30 current state. [0059] 103: The controlling device sends the graphical interaction interface in a form of a data stream to an interaction device for display. [0060] In an embodiment, the controlling device may encode the graphical interaction interface into a video stream of the graphical interaction interface, and send the video stream of the graphical 16 interaction interface to the interaction device, so that the interaction device decodes the video stream of the graphical interaction interface after receiving the video stream of the graphical interaction interface and renders the decoded video stream of the graphical interaction interface into the graphical interaction interface including the parameter information of the controlled device in 5 the current state. [0061] 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 10 interface. [0062] 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 15 interface. [0063] 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 20 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. [0064] 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. 25 [0065] 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. [0066] 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 30 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. 17 [0067] 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 5 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. [0068] By implementing the method described in FIG. 1, a user does not need to perform related 10 intelligent control on a controlled device by using an intelligent chip, a display screen, and complex keys integrated in the controlled device; and the user can perform intelligent control on the controlled device only 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, 15 conveniently, and fast. [0069] 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 20 intelligent control, increases actual utilization of the controlled device, and benefits promotion and popularization of the controlled device. [0070] 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 interaction device, thus the present invention 25 has good adaptability. [0071] Referring to FIG. 2, FIG. 2 is a schematic diagram of a network architecture for intelligently controlling a device according to an embodiment of the present invention. In the network architecture for intelligently controlling a device shown in FIG. 2, a controlling device can establish a communication connection to an interaction device through a network connection (which 30 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 for intelligently controlling a device shown in FIG. 2, the controlling device 18 establishes a connection to a controlled device (such as, a refrigerator) through a USB interface. As a control core for intelligently controlling a device, the controlling device may have an intelligent operating system such as Android (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 5 intelligently controlling a device disclosed in the embodiment of the present invention. Also referring to FIG. 3, FIG. 3 is a flowchart of another method for intelligently controlling a device based on the network architecture for intelligently controlling a device shown in FIG. 2 according to an embodiment of the present invention. As shown in FIG. 3, the method for intelligently controlling a device may include the following steps. 10 [0072] 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 instruction to the controlled device through the USB interface. [0073] 302: The controlled device queries parameter information of the controlled device in a current state in response to the parameter information query instruction sent by the controlling 15 device. [0074] The parameter information query instruction is used for instructing the controlled device to query the parameter information of the controlled device in the current state. [0075] 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 20 parameter, a light working mode parameter of the refrigerator in the current state, even a type or a quantity of food in the refrigerator, or the like. [0076] 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. 25 [0077] 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. [0078] 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 of the 30 graphical interaction interface, and sends the video stream of the graphical interaction interface to an interaction device through Wi-Fi. [0079] 306: After receiving the video stream of the graphical interaction interface sent by the controlling device, the interaction device decodes the video stream of the graphical interaction interface, renders the decoded video stream of the graphical interaction interface into the graphical 19 interaction interface including the parameter information of the controlled device in the current state, where the graphical interaction interface is displayed on a screen of the interaction terminal. [0080] 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. 5 [0081] 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. [0082] Content of the gesture triggered by the user based on the parameter information included 10 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. [0083] 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 15 through Wi-Fi. [0084] 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 20 parameter information included in the graphical interaction interface. [0085] 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 25 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. [0086] In the embodiment of the present invention, through the foregoing steps 307 to 308, the 30 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. 20 [0087] 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. [0088] 312: The controlled device performs, in response to the control instruction, an 5 adjustment corresponding to the parameter information included in the graphical interaction interface, so as to implement intelligent control on the controlled device. [0089] In the embodiment of the present invention, 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; and by implementing the method described in FIG. 3, a 10 user does not need to perform related intelligent control on a controlled device by using an intelligent chip, a display screen, and complex keys integrated in the controlled device, and the user can perform intelligent control on the controlled device only 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 15 can be performed simply, conveniently, and fast. [0090] 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 20 intelligent control, increases actual utilization of the controlled device, and benefits promotion and popularization of the controlled device. [0091] 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 interaction device, thus the present invention 25 has good adaptability. [0092] 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 invention further discloses a network architecture for upgrading a program. By using the network 30 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. A schematic diagram of the network architecture for upgrading a program disclosed in the embodiment of the present invention is shown in FIG. 4, 21 where the network architecture includes a cloud server, a controlling device, a controlled device, and a wireless router. The controlling device accesses, 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 (Internet), so as to establish a connection between the controlling device 5 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 for upgrading a program shown in FIG. 4 is shown in FIG. 5, and the method includes the following steps. 10 [0093] 501: A controlling device sends a type acquiring instruction to a controlled device. [0094] The type acquiring instruction is used for instructing the controlled device to acquire type information of the controlled device. [0095] 502: The controlled device sends the type information of the controlled device to the controlling device in response to the type acquiring instruction. 15 [0096] 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. [0097] 503: The controlling device sends identity information of the controlling device and the type information of the controlled device to a cloud server. [0098] 504: After authenticating the identity information of the controlling device to be valid, 20 the cloud server sends, to the controlling device, a device control service program matching with the type information of the controlled device. [0099] 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. 25 [0100] 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. [0101] 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 30 controlling a device described in FIG. 3. [0102] 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. 22 [0103] 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, 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, so that a user does 5 not need to perform related intelligent control on a controlled device by using an intelligent chip, a display screen, and complex keys integrated in the controlled device, and can perform intelligent control on the controlled device only 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 10 simply, conveniently, and fast. [0104] 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 15 controlled device, and benefits promotion and popularization of the controlled device. [0105] 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 interaction device, thus the present invention has good adaptability. [0106] In an embodiment, before the controlling device downloads the device control service 20 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; and 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 25 from the cloud server in the network architecture for upgrading a program shown in FIG. 4. Correspondingly, an embodiment of the present invention 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. 30 [0107] 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. [0108] 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 23 service program matching with the version information of the device identification service program. [0109] In the embodiment of the present invention, after the cloud server determines through authentication that the identity information of the controlling device is valid, the cloud server may first determine whether an upgrade packet of the device identification service program matching 5 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, 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; or if the upgrade packet of the device identification service 10 program matching with the version information of the device identification service program is not stored, 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 15 matching with the version information of the device identification service program. [0110] 603: After receiving the upgrade packet of the device identification service program matching with the version information of the device identification service program, the controlling device may update and upgrade the device identification service program by using the upgrade packet of the device identification service program matching with the version information of the 20 device identification service program, to obtain an upgraded device identification service program, where the upgrade packet of the device identification service program is sent by the cloud server. [0111] 604. The controlling device controls the upgraded device identification service program to run, so as to perform the method described in FIG. 5 for downloading a device control service program to a controlling device by using the network architecture for upgrading a program shown 25 in FIG. 4. [0112] By implementing the method described in FIG. 6, a controlling device can update a device identification service program from a cloud server in a network architecture for upgrading a program, thereby performing the method described in FIG. 5 for downloading a device control service program to a controlling device by using the network architecture for upgrading a program 30 shown in FIG. 4. In the embodiment of the present invention, the controlling device can effectively identify more controlled devices by updating a device identification service program, so that an interaction terminal can subsequently perform intelligent control on more controlled devices simply, conveniently, and fast, which extends an application range of intelligent control. [0113] In an embodiment, before a controlling device sends, to an interaction device, a 24 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. For example, after both the controlling device and the controlled device access, through Wi-Fi, a local area network where a 5 wireless router is located, the controlling device may send a broadcast packet; in this way, after the interaction device receives the broadcast sent by the controlling device, the interaction device may send a connection establishment request to the controlling device; and after receiving the connection establishment request sent by the interaction device, the controlling device may send a connection completion response to the interaction device in response to the connection 10 establishment request sent by the interaction device, so as to establish a communication connection between the controlling device and the controlled device. [0114] In the embodiment of the present invention, an interaction device may simultaneously establish a communication connection to one or more controlling devices through Wi-Fi, while a controlling device generally can establish a communication connection to one controlled device 15 through a USB interface. Referring to FIG. 7, FIG. 7 is a schematic diagram of a network architecture for a communication connection according to an embodiment of the present invention. In the network architecture for a communication connection shown in FIG. 7, controlling device 1 may establish a communication connection to controlled device 1 through a USB interface, controlling device 2 may establish a communication connection to controlled device 2 through a 20 USB interface, ... , the rest can be deduced by analogy, and controlling device n may establish a communication connection to controlled device n through a USB interface; 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 25 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. In the network architecture for a communication connection shown in FIG. 7, because the controlling devices and the controlled devices may each have a USB interface, a controlling device 30 may also establish a communication connection to any one of the controlled devices through a USB interface while an interaction device may also establish a communication connection to any one of the controlling devices 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 25 controlled devices by using different interaction devices. [0115] Referring to FIG. 8, FIG. 8 is a structural diagram of an apparatus for intelligently controlling a device according to an embodiment of the present invention, where the apparatus is configured to implement the method for intelligently controlling a device disclosed in the 5 embodiments of the present invention.

When the apparatus for intelligently controlling a device shown in FIG. 8 is used as an independent device or a newly added part of a controlling device to perform the method for intelligently controlling a device disclosed in the embodiments of the present invention, the apparatus for intelligently controlling a device shown in FIG. 8 not only can establish a communication connection to a controlled device (such as, establishing a communication 15 connection through a USB interface), but also can establish a communication connection to an interaction device (such as, establishing a communication connection to an interaction device through Wi-Fi). [0116] In another implementation manner, the apparatus for intelligently controlling a device shown in FIG. 8 may also be a network element device having a function for intelligently 20 controlling a device disclosed in the embodiments of the present invention, where a product form of the network element device may be a home partner device, a router, a gateway device, a network firewall device, a GGSN, a PDSN, or the like. It should be understood that the apparatus for intelligently controlling a device disclosed in the embodiment of the present invention supports being independent and built externally, can interconnect to an existing device, or may also be built 25 inside a network element device of a live network in a manner of a plug-in card or software integration.

[0118] The third unit 803 is further configured to send the control instruction obtained by the fourth unit 804 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 10 device, where 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, thereby implementing intelligent control on the controlled device. [0119] In the embodiment of the present invention, a manner for the fourth unit 804 to parse the 15 input event to obtain the control instruction corresponding to the parameter information included in the graphical interaction interface is specifically as follows: the fourth unit 804 converts the input event into an input event matching with the graphical interaction interface generated by the controlling device, and parses the input event obtained through conversion to obtain the control instruction corresponding to the parameter 20 information included in the graphical interaction interface. [0120] In the embodiment of the present invention, the fourth unit 804 may receive a 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, and parse the gesture, to obtain the control instruction corresponding to the parameter information included in the graphical interaction 25 interface. [0121] By using the apparatus for intelligently controlling a device shown in FIG. 8, a user does not need to perform related intelligent control on a controlled device by using an intelligent chip, a display screen, and complex keys integrated in the controlled device; and the user can perform intelligent control on the controlled device only by triggering, on an interaction device, a gesture 30 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. [0122] In addition, by using the apparatus for intelligently controlling a device shown in FIG. 8, the controlled device only needs to have a basic function actuator and does not need to be integrated 27 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. 5 [0123] Further, by using the apparatus for intelligently controlling a device shown in FIG. 8, 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 interaction device, thus the present invention has good adaptability. [0124] Also referring to FIG. 9. FIG. 9 is a structural diagram of another apparatus for 10 intelligently controlling a device according to an embodiment of the present invention, where the apparatus is configured to implement the method for intelligently controlling a device disclosed in the embodiments of the present invention. The apparatus for intelligently controlling a device shown in FIG. 9 is obtained by optimizing the apparatus for intelligently controlling a device shown in FIG. 8. Besides the units included in the apparatus for intelligently controlling a device shown in 15 FIG. 8, the apparatus for intelligently controlling a device shown in FIG. 9 may further include: a fifth unit 805, configured to send a type acquiring instruction to the controlled device, and receive type information of the controlled device which is sent by the controlled device in response to the type acquiring instruction; a sixth unit 806, configured to send, to a cloud server, identity information of the local 20 end and the type information of the controlled device which is received by the fifth unit 805, and receive a device control service program, which matches with the type information of the controlled device and is sent by the cloud server after the cloud server authenticates the identity information of the local end to be valid, where the device control service program is used to control a device through performing; and 25 a seventh unit 807, configured to control the device control service program which matches with the type information of the controlled device and is received by the sixth unit 806 to run, so as to trigger the first unit 801 to perform the operation of acquiring the parameter information of the controlled device in the current state. [0125] In an embodiment, the apparatus for intelligently controlling a device shown in FIG. 9 30 further includes: an eighth unit 808, configured to send a software upgrade request which carries the identity information of the local end and version information of a device identification service program to the cloud server, and receive an upgrade packet of the device identification service program matching with the version information of the device identification service program, where 28 the upgrade packet of the device identification service program is sent by the cloud server after the cloud server authenticates the identity information of the local end to be valid; a ninth unit 809, configured to update and upgrade the device identification service program by using the upgrade packet of the device identification service program matching with the 5 version information of the device identification service program, to obtain an upgraded device identification service program, where the device identification service program is used to identify a device type through performing, and the upgrade packet of the device identification service program is received by the eighth unit 808; and a tenth unit 810, configured to control the upgraded device identification service 10 program obtained by the ninth unit 809 to run, so as to trigger the fifth unit 805 to perform the operation of sending the type acquiring instruction to the controlled device. [0126] In an embodiment, in the apparatus for intelligently controlling a device shown in FIG. 8 or FIG. 9, the third unit 803 is further configured to receive a connection establishment request sent by the interaction device, and send a connection completion response corresponding to the 15 connection establishment request to the interaction device in response to the connection establishment request sent by the interaction device, so as to establish a communication connection between the apparatus for intelligently controlling a device and the interaction device.
