Background
With the development of the technology of the internet of things, more and more sensors and internet of things equipment need to access the cloud platform. Exchanging data between a device and a platform requires encoding and decoding using a communication protocol. At present, a coding and decoding method which can be compatible with various communication message formats in multiple industries is lacked. The existing ubiquitous non-compatible coding and decoding method only has a parsing rule and lacks a bidirectional communication link maintenance and interaction mechanism.
The prior art scheme can not realize data sharing and completely realizes data synchronization of a plurality of platforms by means of 'one station with multiple transmissions' of equipment. As the number of communication links of the device increases, no friendly link maintenance is performed. The communication charge and power consumption of the equipment are increased, and the data transmission of other links is blocked because the equipment side does not usually have an operating system due to the maintenance failure of a single link. The data synchronization scheme of the prior art cannot meet the requirement of data unification of each platform.
