Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
In some smart home systems, the gateway device is integrated with a voice control function, which is a function in which a user issues a control command to the gateway device through voice. In some cases, the user may move the gateway device in order to use the voice control function of the gateway device, such as: the gateway device is placed in the restaurant and the user wishes to use the voice control function of the gateway device in the living room, and the user moves the gateway device from the restaurant to the living room. Because the gateway device is further integrated with the coordinator, after the geographical location of the gateway device changes, the distance between the coordinator and the terminal device changes, and when the distance between the coordinator and the terminal device increases, the signal strength between the coordinator and the terminal device decreases, which may cause abnormal communication between the coordinator and the terminal device. At this time, the coordinator needs to adjust the routing table according to the geographical location where the coordinator is moved to ensure normal communication between the coordinator and the terminal device. However, it takes a certain time for the coordinator to update the routing table, and communication between the coordinator and the terminal device is interrupted during a period of time for updating the routing table, and although the control client and the gateway device can communicate with each other, the gateway device cannot communicate with the terminal device, so that the gateway device cannot control the terminal device according to the control command sent by the control client during the period of time for updating the routing table.
In the embodiment of the present invention, the gateway device is used as a home control center, and many functions may be integrated on the gateway device, for example: a voice control function and a video monitoring function. If the gateway device is integrated with a voice control function, a user sends a voice command to the gateway device within the range that the gateway device can acquire the voice command, the gateway device receives the voice command and then recognizes the voice command, and executes an action corresponding to the voice command, such as controlling a terminal device in a ZigBee network according to the voice command or moving to a designated position according to the voice command; if the gateway device is integrated with a video monitoring function, a user can perform dynamic video monitoring on the environment in a family through the gateway device, for example, if the user has a child in the family, the user hopes to know the activity state of the child in time through the dynamic video monitoring. However, implementing the voice control function of the gateway device requires the user to send a voice command within a range in which the gateway device can acquire the voice command, and implementing the video monitoring function of the gateway device requires the gateway device to be able to move continuously, i.e., the voice control function and the video monitoring function have higher requirements for the location of the gateway device.

Referring to fig. 3, a flowchart of a control method of a terminal device system according to another exemplary embodiment of the present invention is shown. The present embodiment is exemplified by applying the control method to the ZigBee system shown in fig. 1. The control method comprises the following steps:
in step 301, the gateway device moves through the mobile component at least one geographic location within the range of motion.
The gateway equipment provides a video and voice control function and/or a video monitoring function in the moving process.
When the gateway equipment moves in the moving range, the gateway equipment moves along with the human body moving information, or moves along with the sound source position, or moves according to a moving instruction sent by the control client.
Optionally, the gateway device provides a video monitoring function during the moving process. The gateway equipment is also provided with a camera assembly, collects human body movement information through the camera assembly, and moves along with the collected human body movement information through the movement assembly.
When the user moves in the range that the human movement information can be collected by the camera assembly of the gateway equipment, the gateway equipment automatically collects the human movement information through the camera assembly.
Such as: the gateway equipment is a movable robot with a camera component, and when the movable robot collects human body movement information, namely a user walks in front of the movable robot, the movable robot moves along the movement track of the user.
Optionally, the gateway device provides a voice control function during the moving process. Still be provided with the speech recognition subassembly on the gateway equipment, the gateway equipment passes through the speech recognition subassembly and discerns the sound source position, moves at the migration range through moving the subassembly and following the sound source position.
The sound source position can change, and when the sound position identified by the gateway equipment through the voice recognition component changes, the gateway equipment moves in the moving range along with the sound source position through the moving component.
Such as: the gateway equipment stays at a position A in the moving range, a user speaks at a position B in the moving range, the gateway equipment recognizes that the sound source position is the position B through the voice recognition component, and then the gateway equipment moves from the position A to the position B along with the sound source position through the moving component; if the user walks to the position C again and speaks, the gateway equipment recognizes that the sound source position is the position C through the voice recognition component, and then the gateway equipment moves to the position C from the position B along with the sound source position through the moving component.
Optionally, the control client sends a moving instruction to the gateway device through the wide area network, the gateway device receives the moving instruction sent by the control client, and the gateway device moves according to the indicated position of the moving instruction through the moving component.
Such as: the gateway device is originally in a living room of a user home, the user needs to move the gateway device to a bedroom, the user sends a moving instruction to the gateway device through the control client, after the gateway device receives the moving instruction, the position indicated by the moving instruction is determined to be the bedroom, and then the gateway device moves to the bedroom from the living room.
Step 302, the gateway device searches for the ZigBee router in the ZigBee network at the current geographic position in the moving range.
And after the gateway equipment moves, searching the ZigBee network at the current geographic position.
When the ZigBee network is searched, step 303 is performed.
And step 303, when the gateway device searches the ZigBee router, establishing connection with the searched ZigBee router.
Specifically, the gateway device sends an identity to the searched ZigBee router.
Optionally, a set of instruction transmission specifications is predefined in an application layer of the ZigBee network, the transmission specifications define an identity identifier as a terminal device for the gateway device, and the gateway device sends the identity identifier to the ZigBee router according to the transmission specifications when searching for the ZigBee router.
Optionally, the identity is a special predetermined Cluster ID (Cluster Identification), or the identity is a special bit state value under a certain general Attribute ID (Attribute Identification), such as: the special bit state value is 0xF 1.
And step 304, the ZigBee router accesses the gateway equipment into the ZigBee network.
Specifically, the ZigBee router receives an identity sent by the gateway device, the ZigBee router sends the received identity to the coordinator, the coordinator receives the identity sent by the ZigBee router, and the gateway device is added into the ZigBee network according to the identity.
Optionally, the coordinator adds the identity of the gateway device to the routing table, that is, the coordinator adds the gateway device to the ZigBee network.
And 305, controlling the terminal equipment in the ZigBee network by the gateway equipment.
This step can be implemented in two ways, specifically, which way is selected by the coordinator, or set by the user on the coordinator:
firstly, the gateway equipment directly controls the terminal equipment. As shown in fig. 4A, this step can be implemented by the following steps:
step 401, the gateway device sends a control instruction to the ZigBee router.
And the gateway equipment sends a control instruction to the connected ZigBee router. Optionally, the gateway device receives, through the WiFi network, an instruction sent by the control client, and converts the instruction into a control instruction that can be executed by a device in the ZigBee network.
Optionally, the gateway device obtains a voice instruction, such as: the gateway equipment collects voice instructions through a microphone; the gateway equipment identifies the collected voice command through the voice identification component and converts the identified voice command into a control command. The converted control instructions can be recognized and executed by devices in the ZigBee network.
Such as: the terminal equipment comprises an air conditioner with temperature measurement capability, a user sends a voice command to the gateway equipment to open the bedroom air conditioner, the gateway equipment recognizes that the voice command is 'open the bedroom air conditioner', converts the voice command into a control command to 'open the bedroom air conditioner', and sends the control command 'open the bedroom air conditioner' to the ZigBee router.
And 402, the ZigBee router receives a control instruction and determines the controlled terminal equipment according to the control instruction.
And step 403, the ZigBee router determines a transmission path of the control instruction and sends the control instruction to the controlled terminal equipment according to the transmission path.
Such as: as shown in fig. 4B, if the gateway device 40 needs to control the terminal device 44, the ZigBee router determines that the transmission path of the control instruction is the ZigBee router 41-coordinator 42-ZigBee router 43-terminal device 44, and sends the control instruction to the terminal device 44 according to the transmission path, the ZigBee router 41-coordinator 42-ZigBee router 43-terminal device 44. Or the gateway device 40 needs to control the terminal device 45, the ZigBee router determines that the transmission path is the ZigBee router 41-terminal device 45, and sends the control instruction to the terminal device 45 according to the transmission path, the ZigBee router 41-terminal device 45.
And secondly, the gateway equipment controls the terminal equipment through a coordinator in the ZigBee network. As shown in fig. 4C, this step can be implemented by the following steps:
and step 404, the gateway equipment sends a control instruction to the ZigBee router.
This step has already been explained in step 401 and will not be described here.
Step 405, the ZigBee router receives a control instruction.
And step 406, the ZigBee router sends a control instruction to the coordinator.
Step 407, the coordinator receives the control instruction, and determines the controlled terminal device according to the control instruction.
Such as: as shown in fig. 4B, the gateway device 40 first sends the control instruction to the ZigBee router 41, the ZigBee router 41 sends the control instruction to the coordinator 42, and the coordinator 42 determines that the controlled terminal device is the terminal device 44 according to the control instruction.
And step 408, the coordinator determines a transmission path of the control command and sends the control command to the controlled terminal equipment according to the transmission path.
Such as: the controlled terminal equipment is terminal equipment 44, the coordinator 42 determines that the transmission path is the coordinator 42-the ZigBee router 43-the terminal equipment 44, and sends a control instruction to the terminal equipment 44 according to the transmission path coordinator 42-the ZigBee router 43-the terminal equipment 44.
Step 306, the terminal device sends data to the gateway device.
The data sent by the terminal device is used for indicating the self state of the terminal device or indicating the environmental state of the environment where the terminal device is located.
When the self state of the terminal device changes, the terminal device needs to send data to the gateway device. Or, when the environmental state of the environment where the terminal device is located changes, the terminal device needs to send the acquired data to the gateway device, where the environmental state includes light intensity, temperature, humidity, volume, and the like. Such as: the terminal equipment is an air conditioner comprising a temperature sensor, and when the terminal equipment detects that the indoor temperature is lower than 26 ℃, the terminal equipment sends the collected temperature to the gateway equipment.
The step has the following two implementation modes:
firstly, the terminal equipment directly sends data to the gateway equipment.
The terminal device directly sends data to the gateway device, that is, a transmission path of the terminal device sending data to the gateway device does not pass through the coordinator.
Such as: as shown in fig. 5, the terminal device 56 transmits data to the gateway device 50, and the terminal device 56 transmits data to the gateway device 50 through the transmission path terminal device 56-ZigBee router 57-ZigBee router 51-gateway device 50.
And secondly, the terminal equipment sends data to the coordinator firstly, and then the coordinator sends the data to the gateway equipment.
After the coordinator receives the data sent by the terminal device, the data can be sent to the gateway device in the following two ways.
And (I) after receiving the data sent by the terminal equipment, the gateway equipment directly forwards the data to the gateway equipment.
Specifically, the terminal device sends data to the coordinator; the coordinator receives the data and forwards the data to the gateway device.
Optionally, after receiving the data sent by one terminal device, the coordinator immediately forwards the data to the gateway device.
Such as: as shown in fig. 5, the terminal device 55 needs to send data to the gateway device 50, the terminal device 55 first sends data to the coordinator 53 through the transmission path terminal device 55, the ZigBee router 54 and the coordinator 53, and after receiving the data sent by the terminal device 55, the coordinator 53 forwards the data to the gateway device through the transmission path coordinator 53, the ZigBee router 51 and the gateway device 50.
And secondly, after the coordinator receives the data sent by the terminal equipment, the coordinator carries out splicing processing on the received data sent by the plurality of terminal equipment and then sends the spliced data to the gateway equipment.
Specifically, the terminal device sends first data to the coordinator; the coordinator receives the first data, performs splicing processing on the first data to obtain second data, and sends the second data to the gateway device.
Such as: as shown in fig. 5, when the terminal device 52 and the terminal device 55 need to send data to the gateway device 50, the terminal device 55 sends the first data 1 to the coordinator 53, the terminal device 52 sends the first data 2 to the coordinator 53, and after the coordinator 53 receives the first data 1 and the first data 2, the first data 1 and the first data 2 are spliced to obtain the second data, and then the second data is sent to the gateway device 50 through the transmission path coordinator 53-the ZigBee router 51.
It should be noted that step 305 may also be executed before step 304, which is not limited by the embodiment of the present invention.
And step 306, the gateway device receives the data sent by the terminal device.
Corresponding to step 306, this step has two implementations as follows:
firstly, the gateway equipment receives data directly sent by the terminal equipment.
Such as: as shown in fig. 5, the terminal device 56 transmits data to the gateway device 50 through the transmission path terminal device 56-ZigBee router 57-ZigBee router 51-gateway device 50, and the gateway device 50 receives the data transmitted by the terminal device 56.
And secondly, the gateway equipment receives the data sent by the coordinator.
Accordingly, the gateway device receives data differently because the coordinator processes the data differently.
And (I) after the coordinator receives the data sent by the terminal equipment, directly forwarding the data to the gateway equipment, and receiving the data forwarded by the coordinator by the gateway equipment.
Such as: as shown in fig. 5, the terminal device 55 needs to send data to the gateway device 50, the terminal device 55 first sends data to the coordinator 53 through the transmission path terminal device 55, the ZigBee router 54 and the coordinator 53, after the coordinator 53 receives the data sent by the terminal device 55, the data is forwarded through the transmission path coordinator 53, the ZigBee router 51 and the gateway device 50, and the gateway device 50 receives the data forwarded by the coordinator 53.
And (II) when the coordinator receives the data sent by the terminal equipment, processes the data, sends the processed data to the gateway equipment, and the gateway equipment receives the data processed by the coordinator.
Specifically, the coordinator receives data sent by the terminal device, splices the data, and sends the spliced data to the gateway device; and the gateway equipment receives the data spliced by the coordinator.
Such as: as shown in fig. 5, when the terminal device 52 and the terminal device 55 need to send data to the gateway device 50, the terminal device 55 sends the first data 1 to the coordinator 53, the terminal device 52 sends the first data 2 to the coordinator 53, after the coordinator 53 receives the first data 1 and the first data 2, the first data 1 and the first data 2 are spliced to obtain the second data, and then the second data is sent to the gateway device 50 through the transmission path coordinator 53-the ZigBee router 51, and the gateway device 50 receives the second data sent by the coordinator 53.
