The current market of IOT is confronted with two main characteristics.The first is chimney type

it refers that IOT application system is a is a relatively closed system from the terminal to the application platform

its computation

communication and network capacity are served only to the system itself

and not shared with other systems

which causes longer development cycle and higher cost.The second is fragmentation

it refers that the IOT market is isolated to meet the individual requirements of customers

and could not be copied to other customers

which results in that the scale of terminal is small

and the deployment cost of the IOT system is too high.It has been proved by the development history of communications and network that standardization is an effective solution to the chimney type and fragmentation.This article introduces the standard system of IOT from three facets

technical architecture

key technology

and standardization.
