7. An IOT platform protocol adaptation device based on cloud native, comprising:
the cloud IOT platform is used for selecting network component types, addresses, ports and private configuration items according to the accessed side IOT platform and a data transmission protocol and a network transmission protocol required by the terminal equipment to obtain a configured network adaptation component; according to the protocol adaptation package developed by the project access equipment and the analysis parameters of the configured components, the configured protocol adaptation components are obtained; creating product metadata according to the product specification and the product description information, and associating the network adaptation component and the protocol adaptation component to obtain a product adaptation component assembled according to the requirement; issuing the product adaptation components which are assembled in advance according to the requirements to an edge IOT platform;
and the side IOT platform is used for checking the product adaptation component issued by the cloud IOT platform, if the product adaptation component passes the checking, creating a resource deployment file and a service configuration file according to the product adaptation component, and starting a container according to the resource deployment file and the service configuration file.
8. A cloud-native based IOT platform protocol adaptation device, comprising a processor and a memory storing program instructions, the processor configured, when executing the program instructions, to perform the cloud-native based IOT platform protocol adaptation method of any of claims 1-6.
9. A computer readable medium having stored thereon computer readable instructions for execution by a processor to implement a cloud native based IOT platform protocol adaptation method according to any of claims 1 to 6.
