The information of the device may be a unique code, address information and/or interface information of the device.
The sending equipment is intelligent equipment, and the receiving equipment is control equipment. Further, response information from the intelligent device is received, and control equipment corresponding to the response information is determined; after executing the control instruction, the intelligent device feeds back response information to the control device which sends the control instruction. After the gateway server sends the control instruction from the control device to the intelligent device, the connection between the gateway server and the control device and the connection between the gateway server and the intelligent device are not disconnected for a while, so that after response information fed back by the intelligent device is received, the control device corresponding to the response information can be directly determined according to communication connection.

Further, in the registration information of the registered device, the version number of the communication protocol supported by the intelligent device is inquired.
And the protocol converter is used for converting the format of the information into a format which can be recognized by the receiving equipment. Further, the format refers to: frame transmission format.
Specifically, the version number of the communication protocol supported by the receiving device may be queried in the network, or the version number of the communication protocol supported by each device connected to the gateway service may be set in advance.
On the gateway server side, a protocol converter corresponding to the version number of each communication protocol is set in advance. Further, in the version number of the communication protocol supported by each device connected to the gateway server, a protocol converter corresponding to the version number of each communication protocol is set in advance.
The protocol converter is a virtual device installed in the gateway server; or, the protocol converter is an entity device which is internally or externally arranged on the gateway server.
Step S230, sending the converted information to the receiving device.
In this embodiment, when the sending device and the receiving device support different communication protocols, the gateway server may perform protocol conversion on information sent from the sending device to the receiving device, so that the converted information can be recognized by the receiving device, and thus, a plurality of devices respectively supporting different communication protocols coexist in an environment of the internet of things and are controlled by the same control device.
In this embodiment, a cloud compatible mode is adopted, and the protocol of the sending device and the protocol of the receiving device are converted by using the gateway server, so that the converted information can be identified by the receiving device, the problem of coexistence of different devices in the same internet of things environment is solved, and the different devices can be normally used. Further, the present embodiment can avoid the following problems: when the APP directly supports the compatibility of different devices, the APP needs to include codes of compatible processing of each device in the codes, so that the APP codes are huge, the downloading and updating speed of the APP is slowed, and the user experience is influenced.

The device where the APP is located is a control device. This APP is used for controlling smart machine. The communication protocol supported by the APP can be determined by pre-negotiation between the APP and the gateway server.
The APP receives user operation and generates a corresponding control instruction according to the user operation; and the APP sends the control request information carrying the control instruction to the gateway server through the network.
For example: the user clicks a button for starting the intelligent air conditioner in the APP, a control instruction for starting the intelligent air conditioner is generated according to the clicking operation of the user, and the control instruction is sent to the gateway server, so that the control instruction is sent to the intelligent air conditioner through the gateway server.
According to the interface receiving the control instruction, the APP sending the control instruction can be determined, the communication protocol supported by the APP can be further determined, and the control instruction can be analyzed according to the communication protocol.
The control instruction comprises a source address and a destination address, wherein the source address is the address of the sending device, namely the address of the control device where the APP is located, and the destination address is the address of the receiving device. Thus, the receiving device of the control instruction can be determined according to the destination address.
Step S320, the gateway server queries the information of the receiving device in the control instruction, determines a version number of the communication protocol that can be identified by the receiving device, and determines a first protocol converter corresponding to the version number of the communication protocol.
The information of the receiving device may be a device unique code from which it can be used to query and determine the version number of the communication protocol that the receiving device can identify (support).
In this embodiment, the protocol converter may be a code for protocol conversion.
Step S330, the gateway server invokes the first protocol converter, converts the control instruction from the APP into a control instruction that can be recognized by the receiving device, and issues the converted control instruction to the corresponding receiving device.
In step S340, the receiving device receives the control instruction sent by the gateway server, executes the control instruction, and returns a response result of the execution instruction as response information to the gateway server.
Similarly, the source address and the destination address are also included in the response message.
Step S350, the gateway server queries the information of the APP in the response result, determines a version number of a communication protocol that can be identified by the APP, and determines a second protocol converter corresponding to the version number of the communication protocol.
Step S360, the gateway server invokes the second protocol converter to convert the response information into response information that can be identified by the APP.
Step S370, the gateway server returns response information that the APP can recognize to the APP.
And the APP executes corresponding actions according to the response information. For example: prompt the user for success or failure, and so on.
