Fig. 1 is a schematic flowchart of a control method according to a first embodiment of the invention; as shown in fig. 1, the control method includes:

step 101: and obtaining the linkage rule.

In this embodiment, the first central control device and the other central control devices have a message forwarding function, and control the smart home devices connected to the central control device or the other central control devices based on various sent messages. The first central control device and the other central control devices form a multi-level control system, and the first central control device and the other central control devices can be specifically realized by a router. Specifically, the multi-level control system may be a multi-level control system of a certain user, for example, a home of the user has multiple rooms, and each room performs message forwarding through a central control device; or the home of the second user and the home of the parent of the second user are associated to be the same user name, each room in the home of the second user is forwarded through one central control device, each room in the home of the parent of the second user is forwarded through one central control device, and the home of the second user and the home of the parent of the second user are forwarded through one total central control device to the central control device in the home of the second user and the central control device in the home of the parent of the second user. Taking the first central control device and the other central control devices as routers as an example, fig. 2 is a topological diagram of a multi-level control system in the embodiment of the present invention, as shown in fig. 2, the multi-level control system includes a first-level router 1, a router 1.1 and a router 1.2 connected to the router 1, a router 1.1.1 connected to the router 1.1, an intelligent home device 2 and an intelligent home device 3, an intelligent home device 4 connected to the router 1.2, an intelligent home device 5 and an intelligent home device, and an intelligent home device 1 connected to the router 1.1.1; the intelligent household equipment in the multilevel control system can be any intelligent equipment which can be wirelessly connected and has a wireless control function, such as an intelligent bulb, an intelligent socket, various intelligent household appliances or various sensors, and the like, wherein the sensors are not limited to motion sensors, temperature sensors, humidity sensors and distance sensors; the intelligent household equipment and the central control equipment can be connected based on at least one transmission protocol, and the transmission protocol is not limited to local area network transmission protocols such as a Bluetooth transmission protocol or a Zigbee transmission protocol. The central control devices are connected based on a preset communication Protocol, and the preset communication Protocol is not limited to Point-to-Point protocols (PPPoE, Point-to-Point Protocol over Ethernet) and the like on the Ethernet.

Here, each central control device of the multi-level control system stores therein a linkage rule related to the smart home device to which the central control device is directly or indirectly connected, and thus the linkage rule stored in each central control device may be different. As shown in fig. 2, the linkage rule stored in the router 1.1 is related to the smart home devices 1, 2 and 3, wherein the smart home devices 2 and 3 are directly connected to the router 1.1, and the message forwarding is performed between the smart home devices 1 and 1.1 through the router 1.1.1, so that the smart home devices 1 and 1.1 are indirectly connected. The linkage rule includes a trigger condition of any one of the smart home devices 1, 2 and 3 and a state that the other smart home devices need to be linked to switch after the trigger condition is triggered. Table 1 is a schematic table of the linkage rule in the embodiment of the present invention, which is a schematic diagram of the linkage rule in the router 1.1, and as shown in table 1, when the state of the smart home device 1 is the start (on) state, the smart home device 2 is triggered to execute the start (on) action, and the color value of the state bit where the smart home device 2 is started is [20,50,100], and the brightness value is 80. As can be seen from table 1, the state of the smart home device 3 is irrelevant to the states of the smart home device 1 and the smart home device 2, and therefore, the smart home device 3 has no linkage relationship with the smart home device 1 and the smart home device 2.

Device name	Status set name	Status value
			Intelligent household equipment 1	On/off	1
Intelligent household equipment 2	color	[20,50,100]
			Intelligent household equipment 2	brightness	80
Intelligent household equipment 2	On/off	1
			Intelligent household equipment 3	temperature	23

Here, the device state of the first smart home device is not limited to the on/off state of the device, and may be a state when the detected first parameter reaches the first threshold. For example, when the first smart home device is a temperature sensor, when a temperature value detected by the temperature sensor reaches a first threshold value, the state of the temperature sensor is determined to be a first state, and when the temperature value detected by the temperature sensor reaches a second threshold value, the state of the temperature sensor is determined to be a second state. Alternatively, the state at which the detected first parameter reaches the first threshold may be a state that characterizes other devices reached. For example, the first smart home device is a distance sensor, the distance sensor is arranged inside a door frame of a room, and the distance between the first smart home device and the door can be detected through the distance sensor so as to determine whether the door is in an open state or a closed state at the moment.

After the smart home device 1 described in table 1 is triggered to satisfy the first state, correspondingly, the smart home device 2 needs to execute a specific action and satisfy the specific state.

Step 104: determining a shortest transmission path between the first intelligent household equipment and the second intelligent household equipment based on the synchronization information; the shortest transmission path is a transmission path between the central control devices of the multi-stage control system.

Specifically, the synchronization information includes address information of the other central control devices and identifiers of the smart home devices connected to the other central control devices. Table 2 is a schematic table of the synchronization information in the embodiment of the present invention, which is the synchronization information in the router 1.1 shown in fig. 2. As shown in table 2, the router 1.1 stores the address of the smart home device 2, the address of the smart home device 3, and the address of the previous-stage router 1, which are directly connected to the router 1.1, and further includes the address of the smart home device 1 attached to the router 1.1.1, and in this illustration, the address of the smart home device 1 is represented by the address of the router 1.1.1.

		Intelligent household equipment 3	Address of intelligent household equipment 3
Others	Address of router 1
