Encoding and decoding method and device, computer readable medium and Internet-of-Things equipment

Abstract

The invention provides an encoding and decoding method and device, a computer readable medium and Internet of Things equipment. The encoding and decoding method comprises the following steps: creatingat least one encoder and decoder selection strategy in advance; creating at least one encoding and decoding unit, and creating at least one encoding and decoding device by using the at least one encoding and decoding unit; determining an executed target codec selection strategy according to the current configuration parameters in the system context; according to currently input parameters and thetarget codec selection strategy, selecting a target codec and outputting the target codec; and utilizing at least one target encoding and decoding unit in the target codec to perform encoding and decoding in positive and negative directions on equipment input of external input, and outputting a result. According to the scheme, different encoding and decoding requirements can be flexibly met.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, and in particular to a codec method, device, computer-readable medium, and Internet of Things equipment. Background technique [0002] When a device in the Internet of Things environment communicates with the outside world, it often encodes the content of the communication. Through appropriate coding, the communication content can be greatly simplified, the message length can be reduced, and the network load pressure can be reduced. On the receiving side, it needs to perform byte-by-byte and bit-by-bit decoding according to the agreed codec specification, and restore the simplified binary message to meaningful content. [0003] There are various complex situations in practical applications, which make it difficult to be compatible with different types of equipment or different versions of communication protocols. Software designers often need to customize the design and implementatio...

Problems solved by technology

The embodiment of the present invention obtains the configuration information, the data to be converted and the expected message type, and processes the data to be converted to obtain the processed data to be converted, and then obtains the node information of the corresponding codec node from the configuration information according to the expected message type, And generate the codec method according to the node information, and finally perform the corresponding codec operation on the processed data to be converted according to the generated codec method, and obtain the codec result. This process can reduce the development and access of devices using the message protocol. Apply the workload of the two processes of the device platform, and increase the stability and fault tolerance of the message parsing process, but do not provide a solution to flexibly implement different encoding and decoding requirements
