The MQTT server 103 is used for returning the topology message to the IOT cloud platform 102;
the IOT cloud platform 102 is configured to perform validity verification on the topology message, generate response information, and send the response information to the gateway device 100 through the MQTT server 103;

The system further comprises a control terminal 101, which is used for inquiring the corresponding distribution network model information of the control terminal 101 from the IOT cloud platform 102 when the gateway device 100 and the MQTT server 103 are successfully networked.

Specifically, the IOT cloud platform of this application carries out reasonable division to system's function, guarantees the unicity of each subsystem function, easily extension, simultaneously, through infrastructure's construction, carries out real time monitoring to application health status, guarantees IOT cloud platform's stability. The architecture of the IOT cloud platform is shown in fig. 2, and fig. 2 is a schematic structural diagram of the IOT cloud platform architecture of the present application. The product function architecture comprises the following parts:

As shown in fig. 3, a method for getting on the line of the sub-device in one embodiment of the present invention is provided. The online method includes steps S10 to S50.
And step S10, after the gateway device is online based on the wifi mesh network, the gateway device calculates the sub-devices which are not added into the current gateway topology.
Specifically, the wifi mesh network (wireless mesh network), also called "multi-hop" network, of the present embodiment is a new wireless network technology, and is completely different from the conventional wifi network. The wifi mesh network is a network technology based on multi-hop routing and peer-to-peer network, and is a new network structure. And when the gateway equipment is successfully online, the gateway equipment and the MQTT server are successfully networked, and the gateway equipment calculates the sub-equipment which is not added into the current gateway topology. The sub-devices may be household electrical appliances in the whole house interconnection, for example, devices such as an intelligent clothes hanger, an intelligent television, an intelligent gas stove, and the like.
MQTT (Message Queuing Telemetry Transport) is a "lightweight" communication protocol based on publish/subscribe (publish/subscribe) mode. It will be appreciated that the MQTT server is a message queue server.
After the gateway device successfully gets on line under the wifi mesh network, the sub-device can get on line, and because the gateway device can be any one household appliance in the whole house interconnection, more sub-devices can be connected, the limitation problem of the number of the household appliances connected when the router directly serves as the gateway device is effectively avoided.
Step S20, the gateway device sends the topology message corresponding to the child device to the MQTT server based on the protocol defined by the IOT cloud platform.
Specifically, after the gateway device calculates the sub-devices that do not join the current gateway topology, the gateway device sends the topology messages corresponding to the sub-devices to the MQTT server according to the protocol defined between the gateway device and the IOT cloud platform. The topology message of the child device refers to a message such as a physical connection relationship between the child device and each device.
Step S30, the MQTT server returns the topology message to the IOT cloud platform.
Specifically, the topology message of the child device is finally subjected to validity verification by the IOT cloud platform, but the child device is not on-line yet and cannot interact with the IOT cloud platform. Therefore, the MQTT server is required to forward the topology message to the IOT cloud platform, so that the IOT cloud platform can perform validity verification on the topology message.
Step S40, the IOT cloud platform carries out validity verification on the topology message and sends a verification result to the gateway equipment through the MQTT server.
Step S50, if the verification result is that the verification passes, the gateway device adds the child device to the current gateway topology.
Specifically, after the IOT cloud platform receives the topology message, validity verification is carried out on the topology message, the verification result is sent to the gateway equipment through the MQTT server, and when the validity verification of the topology message passes, the gateway equipment can add the sub-equipment to the current gateway topology to realize the online operation of the sub-equipment; when the validity verification of the topology message fails, the gateway device cannot add the child device to the current gateway topology.
And the verification result obtained by the IOT cloud platform is sent to the gateway equipment through the MQTT server.
The application discloses a method and a system for online of a sub-device, after the gateway device is online based on a wifi mesh network, the gateway device starts to calculate the sub-device which is not added to the current gateway topology, and based on a protocol between the gateway device and an IOT cloud platform, the gateway device sends a topology message corresponding to the sub-device to be added to an MQTT server, the topology message is sent to the IOT cloud platform through the MQTT, the IOT cloud platform carries out validity verification on the topology message, when the verification is passed, the sub-device is added to the current gateway topology of the gateway device, and therefore online operation of the sub-device under the wifi mesh network is achieved.
According to the method and the system, after the sub-equipment is successfully online under the wifi mesh network, all the sub-equipment which is online can be uniformly controlled.
Further, as shown in fig. 4, fig. 4 is a schematic flowchart of another embodiment of an online method of a sub-device of the present application. Before the step of calculating, by the gateway device, the child device that does not join the current gateway topology, the online method may include:
step S11, the control terminal inquires and acquires the model information of the distribution network corresponding to the control terminal from the IOT cloud platform;
step S12, if model information corresponding to the sub-equipment which is not added into the current gateway topology exists in the distribution network model information, the control terminal confirms that the model information corresponding to the sub-equipment is added into the equipment list controlled by the IOT cloud platform to obtain confirmed information;
step S13, the control terminal sends the confirmation information to the gateway device;
the gateway device calculating the child devices which do not join the current gateway topology comprises:
and the gateway equipment calculates the sub-equipment which is not added into the current gateway topology based on the confirmation information.
In some embodiments, before the step of calculating the sub-device not added to the current gateway topology by the gateway device, the control terminal queries from the IOT cloud platform to obtain controllable network model information that can be controlled by the controlling china, and if model information corresponding to the sub-device not added to the current gateway topology exists in the controllable network model information, it is indicated that the control terminal can help the sub-device added to the current gateway topology to go online.
At this moment, the control terminal outputs the model information of the sub-equipment which is not on-line for the user to check, the user can confirm the model information of the sub-equipment which is not on-line according to needs, after the control terminal obtains the confirmed model information, the model information is added into an equipment list controlled by the IOT cloud platform, and the control terminal sends the confirmed information corresponding to the equipment list to the gateway equipment, so that the gateway equipment obtains the information that the model information of the sub-equipment which can be distributed is added into the equipment list. And after the gateway equipment obtains the confirmation information, the gateway equipment calculates the sub-equipment which is not added into the current gateway topology based on the confirmation information.
If the model information corresponding to the sub-equipment which is not added into the current gateway topology does not exist in the distribution network model information, the fact that the control terminal does not exist and can help the sub-equipment which is added into the current gateway topology to be on line is shown.
Further, before the step of validating the validity of the topology message by the IOT cloud platform, the online method may include:
the gateway equipment splices a marker sequence with a preset format to gateway equipment information, and carries out asymmetric encryption on the marker sequence to obtain an encryption result; the gateway equipment encodes the encryption result to obtain an encoding result; and the gateway equipment takes the coding result as a request body to initiate an HTTPS request to the IOT cloud platform, wherein the HTTPS request is the topology message.
Specifically, the gateway device splices a marker sequence in a preset format to the gateway device information, where the preset format may be a json format, and json (javascript Object notification) is a lightweight data exchange format. And after splicing the marker sequences in the preset format, carrying out asymmetric encryption on the marker sequences to obtain an encryption result.
The gateway device then encodes the encryption result, which may be Base64 bit encoding, resulting in an encoded result. And the gateway equipment takes the coding result as a request body to initiate an HTTPS request to the IOT cloud platform as the topology message.
Further, the step of performing validity verification by the IOT cloud platform based on the topology message includes:
after receiving the topology message, the IOT cloud platform decodes and decrypts the topology message to obtain a plaintext request body; the IOT cloud platform uses random encryption parameters to encrypt the plaintext request body on line to obtain an encrypted character string; the IOT cloud platform compares the encrypted character string with the encryption result, if the encrypted character string is equal to the encryption result, the situation that the ciphertext obtained by encrypting the same field by the gateway equipment and the IOT cloud platform is consistent is shown, namely a secret key adopted by the gateway equipment is consistent with a secret key adopted by the IOT cloud platform, and the validity verification is judged to be passed; if the encrypted character string is not equal to the encryption result, it indicates that the ciphertext obtained by encrypting the same field by the gateway device and the IOT cloud platform is inconsistent, that is, the secret key adopted by the gateway device is inconsistent with the secret key adopted by the IOT cloud platform, and it is determined that the validity verification fails.
It should be noted that, after obtaining the request body, the IOT cloud platform performs online decryption through the device identifier in the topology message, performs Base64 decoding, and performs asymmetric decryption to obtain the request body in the plaintext json format.
Further, after step S40, the online method includes:
if the verification result is that the verification is passed, the IOT cloud platform acquires the equipment information corresponding to the sub-equipment based on the topology information; and the IOT cloud platform binds the equipment information and the user information to generate a user relationship and records the user relationship.
Specifically, when the IOT cloud platform passes validity verification of the topology message, the IOT cloud platform obtains device information corresponding to the sub-devices based on the topology message, and can also obtain user information stored by the IOT cloud platform itself, where the user information may include identity information corresponding to each user, generates a user relationship by binding the device information and the user information, and records the user relationship.
For example, the sub-device is an intelligent clothes hanger, the user information is a user a, the relationship between the user a and the intelligent clothes hanger is obtained after the device information and the user information are bound, and after the sub-device of the intelligent clothes hanger is successfully on line, the user a can control the intelligent clothes hanger. And the IOT cloud platform records the user relationship.
Further, after the IOT cloud platform records the user relationship, the IOT cloud platform acquires the device ID, the product ID and the user ID corresponding to the sub-devices based on the user relationship, and acquires the network address allocated by the MQTT server; and the IOT cloud platform records the equipment ID, the product ID, the user ID and the network address.
Specifically, the user relationship includes device information and user information, and the device information includes a device ID and a product ID corresponding to the child device; the user information comprises a user ID, the IOT cloud platform acquires a network address distributed by the MQTT server so as to bring convenience to online of the sub-equipment, and the IOT cloud platform records the equipment ID, the product ID, the user ID and the network address for online use of the sub-equipment.
Further, after the gateway device adds the sub-device to the current gateway topology, the gateway device sends an online message of the sub-device to the MQTT server, so that the MQTT server can know that the sub-device is online; after receiving the online message, the MQTT server generates release information based on the online message; the MQTT server sends the release information to the gateway equipment so that the gateway equipment can obtain the release information conveniently; and the gateway equipment subscribes topic information topic corresponding to the online sub-equipment to the MQTT server based on the publishing information, so that the connection between the gateway equipment and the sub-equipment is realized. And the gateway equipment circulates the flow, confirms that all the sub-equipment is added to the current gateway topology, and realizes the online of all the sub-equipment to be online, thereby realizing the unified management and control of the sub-equipment.
Further, after receiving the online message, the MQTT server sends the online message to the IOT cloud platform for processing to obtain a processing result; the IOT cloud platform is used for processing an online message sent to the MQTT server by the gateway equipment.
