responding to a new protocol conversion program configured in the gateway, and determining a device identifier included in a protocol packet corresponding to the new protocol conversion program;

updating the first corresponding relation according to the equipment identifier corresponding to the new protocol conversion program;

under the condition that the main program is started, starting the plurality of protocol conversion programs and the new protocol conversion program through the main program;

determining a target protocol conversion program corresponding to the first target equipment identifier from the plurality of protocol conversion programs and the new protocol conversion program according to the first corresponding relation through the main program; sending the first message to the target protocol conversion program;

determining, by the target protocol conversion program, a target interface protocol corresponding to the first target device identifier according to a third correspondence in the target protocol conversion program; according to the target interface protocol, the first message is converted to obtain a second message meeting the target interface protocol; and sending the second message to the first target equipment.

2. The method of claim 1, wherein said sending the first message to the target protocol conversion program comprises:

and sending the first message to the target protocol conversion program according to the program address of the target protocol conversion program.

3. The method according to claim 2, wherein a second mapping relationship between a protocol conversion program and a program address is configured in the main program, and before issuing the first message to the target protocol conversion program according to the program address of the target protocol conversion program, the method further comprises:

and determining the program address of the target protocol conversion program according to the second corresponding relation.

4. The method of claim 2, wherein said issuing the first message to the target protocol conversion program according to the program address of the target protocol conversion program comprises:

and calling a message issuing interface according to the program address of the target protocol conversion program, and issuing the first message to the target protocol conversion program.

5. The method of claim 1, wherein sending the second message to the first target device comprises:

and sending the second message to the first target equipment according to the equipment address of the first target equipment.

6. The method according to claim 5, wherein a fourth correspondence between the device identifier and the device address is configured in the target protocol conversion program, and before the second message is sent to the first target device according to the device address of the first target device, the method further includes:

and determining the equipment address of the first target equipment according to the fourth corresponding relation.

7. The method according to any one of claims 1-6, further comprising:

receiving a third message uploaded by a second target device through any one of the plurality of protocol conversion programs and the new protocol conversion program, wherein the third message carries a second target device identifier;

converting the third message according to a reference interface protocol by the protocol conversion program to obtain a fourth message meeting the reference interface protocol, wherein the reference interface protocol is an interface protocol corresponding to the cloud server; uploading the fourth message to the main program;

and receiving the fourth message uploaded by the protocol conversion program through the main program, and uploading the fourth message to the cloud server.

8. The method of claim 7, wherein uploading the fourth message to the main program comprises:

and calling a message uploading interface to upload the fourth message to the main program.

9. The method according to claim 1, wherein a second mapping relationship between a protocol conversion program and a program address is configured in the main program; the method further comprises the following steps:

determining a program address of a protocol conversion program in response to configuring a new protocol conversion program in the gateway;

and updating the second corresponding relation according to the program address of the protocol conversion program.

10. The message sending device is characterized by being applied to a gateway, wherein the gateway comprises a main program and a plurality of protocol conversion programs, and a first corresponding relation between a device identifier and the protocol conversion programs is configured in the main program; the protocol conversion program is used for converting messages and interacting with one or more devices, different protocol conversion programs correspond to different devices, the protocol conversion program is stored in the gateway in the form of a protocol packet, the protocol packet comprises a device identifier and a third corresponding relation between the device identifier and an interface protocol, and the main program and the protocol packet exist independently; the device comprises:

a third determining module, configured to determine, in response to a new protocol conversion program configured in the gateway, a device identifier included in a protocol packet corresponding to the new protocol conversion program;

the updating module is used for updating the first corresponding relation according to the equipment identifier corresponding to the new protocol conversion program;

means for performing the steps of: under the condition that the main program is started, starting the plurality of protocol conversion programs and the new protocol conversion program through the main program;

a first running module, configured to determine, through the main program and according to the first correspondence, a target protocol conversion program corresponding to the first target device identifier from the multiple protocol conversion programs and the new protocol conversion program; sending the first message to the target protocol conversion program;

a second running module, configured to determine, by the target protocol conversion program, a target interface protocol corresponding to the first target device identifier according to a third correspondence in the target protocol conversion program; according to the target interface protocol, the first message is converted to obtain a second message meeting the target interface protocol; and sending the second message to the first target equipment.

11. A gateway, characterized in that the gateway comprises a processor and a memory, in which at least one program code is stored, which is loaded and executed by the processor to implement the operations executed in the message sending method according to any one of claims 1 to 9.

12. A computer-readable storage medium, having at least one program code stored therein, the at least one program code being loaded into and executed by a processor to perform the operations of the method of any one of claims 1 to 9.
