The information processing method of configurable protocol data gateway and gateway based on modelTechnical field
The present invention relates to the communications field, more particularly, to a kind of configurable protocol data gateway and net based on modelThe information processing method of pass.
Background technology
With the development of technology of Internet of things, the demand to communicate between equipment is more and more stronger.And current equipment roomCommunication is mostly in physical layer, therefore produce many general physical layer interfaces, such as RS485, RJ45, CAN etc..ButThe realization in the agreement of physical layer of each producer and industry-by-industry simultaneously differs, this communication between devices from different manufacturers causesInconvenience, forms information island phenomenon.
In order to solve the problems, such as between devices from different manufacturers can not normal communication, people employ the mode of data gateway, i.e.,The agreement of all producers is formed software code to be written in data gateway, since agreement is numerous, the development cycle of gateway protocolAlso long, so this requirement for the processing capacity and memory capacity of data gateway is very high, this results in costIt is very high.On the other hand, for the agreement directly realized with software, direct compilation, when increasing agreement, is gone back into executable codeIt needs that original gateway source code is rewritten and is compiled, this brings great inconvenience to the maintenance of data gateway.CauseHow this, effectively reduce the operating cost of data gateway, and ensure more convenient maintenance, and become needs what is urgently solved at presentProblem.
