Method and device for loading assembly of equipment and internet-of-things system

The embodiment of the invention provides a method for loading an assembly of equipment. The equipment is in communication with a cloud server. The method comprises the steps: the equipment generates an assembly loading request; the equipment sends the assembly loading request to the cloud server; the equipment receives an executable file of a target assembly returned by the cloud server, wherein the executable file of the target assembly is generated by the cloud server according to the assembly loading request; and the equipment runs the executable file of the target assembly to complete loading of the target assembly. In the embodiment, the executable file of the target assembly is generated by the cloud server; after the equipment receives the executable file of the target assembly, theexecutable file can be directly run to complete loading of the target assembly, relocation of a sign is not needed, and the occupation of computing resource in the equipment is reduced.
