Through the steps, first state information of the first equipment is obtained; judging whether the first state information of the first equipment meets a preset linkage condition or not; if the preset linkage condition is met, the equipment state of the second equipment is controlled, the state information of the first equipment is obtained through the second equipment, whether the second equipment needs linkage control or not is judged, the technical problem that equipment linkage consumes server resources in the prior art is solved, mutual subscription and linkage control among the equipment are achieved, when the equipment reaches the preset linkage condition, the preset linkage condition is judged through the equipment, preset operation is executed to achieve linkage among the equipment, and consumption of server resources is reduced.
In this embodiment, acquiring the first state information of the first device includes:
s11, receiving a first theme Message sent by a Message Queue Telemetry Transport (MQTT) server, wherein the MQTT server is connected with the first device and the second device through a Message middleware;
the first subject message includes state information of the first device, identification information of the device, and the like, and the second device can analyze the ciphertext through the server public key and the device public key after receiving the data in the first subject message.
S12, extracting the equipment identification of the first equipment from the first theme message;
the subscribed first subject message contains device identification, such as MAC address information of the device, etc., because such identification information is unique, the device-related family dependency can be queried through such unique information.
S13, judging whether the first device and the second device are in the same family group or not based on the device identification;
and S14, if the first device and the second device are in the same family group, extracting the first state information from the first theme message.
In the above steps, whether the devices are in the same family group is queried through the device identifiers, and if yes, the first state information can be extracted from the first theme message. The definition of the family group is determined by the user through the actual situation, the number of the devices in the family group can be set, the family group can comprise more than two devices, the user can pull other users into the family group, and at the moment, the devices of the two parties are in the same family group.
The first state information can be extracted from the first theme message only after the equipment is identified and inquired in the same family group, optionally, the step of inquiring whether the equipment is in the same family group or not can be carried out before the equipment subscribes the theme, whether the equipment is in the same family group or not is firstly inquired and judged by the equipment identification, the corresponding themes can be mutually subscribed between the equipment when the equipment is in the same family group, so that the linkage safety of the equipment is ensured, and then the state information in the theme can be acquired without judging whether the equipment is in the same family group or not.
In this embodiment, after controlling the device state of the second device, the method further includes: generating second state information of the second device; searching a second subject matched with the second state information; and pushing the second state information serving as the load data of the second theme to an MQTT server.

step S306, pushing the first state information to a second device, so that the second device controls a device state of the second device through the first state information, where the first device and the second device are connected to an MQTT server through a message middleware.
In an implementation manner of this embodiment, the MQTT server determines whether state information of the first device changes, and if the state information of the first device changes, acquires the latest first state information of the first device, stores the latest first state information to the first theme, and pushes the first state information to the second device through the message middleware. When the device state information changes, the data is sent to an IOT (Internet of Things) server through the MQTT, the data is encrypted through a device secret key when the device sends the data, and the IOT server decrypts through a server public key. After data are decrypted, encryption protection is carried out by using a secret key of the server and the data are forwarded to the MQTT server, the IOT server and the MQTT server are mutually independent and can interact through a network, the public key of the server is solidified into the server by both the IOT server and the MQTT server when the server is established, and the public key of equipment in the equipment is also solidified into the equipment. Since the server public key is not transmitted through the network but is solidified in the device, there is no possibility of leakage, i.e., security is guaranteed.
In the embodiment, the server does not need to issue the control command for linkage, so that the problems of linkage failure and the like caused by the loss of the issued command do not need to be worried about, and the usability of the linkage method is ensured.
In this embodiment, before pushing the first state information to the second device, the method further includes: receiving a control instruction submitted by a control terminal, wherein the control instruction is used for indicating the mutual linkage of the first equipment and the second equipment and linkage conditions; judging whether the first device and the second device are in the same family group; and if the first equipment and the second equipment are in the same family group, the control instruction is sent to the second equipment.
In the above steps, the user presets the linkage condition by submitting the control instruction to the control terminal, the server judges that the equipment sends the preset linkage condition to the equipment after judging the equipment in the same family group, the linkage safety is ensured, and the equipment can acquire the equipment state information in the theme after judging the equipment in the same family group or can subscribe the corresponding theme after judging the equipment in the same family group in the previous step, so that the double safety guarantee of equipment linkage is realized.
In this embodiment, determining whether the first device and the second device are in the same family group includes: acquiring a first MAC address of the first device and acquiring a second MAC address of the second device; searching a first family ID of the first MAC address and a second family ID of the second MAC address; judging whether the first family ID is the same as the second family ID; and if the first family ID is the same as the second family ID, determining that the first equipment and the second equipment are in the same family group.
Optionally, in the above step, the number of the obtained MAC addresses is greater than or equal to two, and the number of the searched home IDs is defined by the user according to the actual situation.
Fig. 4 is an overall flowchart of a method for linking devices according to an embodiment of the present invention, including: a device state change; encrypting by using the equipment key; the IOT server decrypts the data by using the server public key and encrypts and transmits the data to the MQTT server by using the server public key; devices of the same family group subscribe to each other; judging whether the equipment reaches a preset condition or not; if the preset condition is met, the devices are linked.
