Design and development of real time data push in web-based automatic irrigation control system

The automatic irrigation control system based on web is a main trend of current water-saving technology development. In order to provide personalized irrigation control scheme and precise water metering, the system needs higher real-time data transmission performance. Aiming at this problem, in this paper, the structure and bottleneck of real-time data transmission of web-based automatic irrigation control system was analyzed, and the data push scheme of improving the real-time performance was proposed. Based on observer pattern, the data push mode between data layer and logic layer, and that between logic layer and presentation layer were specifically designed. The results of this paper showed that, through the reasonable design and development, the real-time performance of the Web based irrigation control system can reach the level of desktop control system. The data push scheme can also be applied to other related monitoring and control software system in internet of things, which can improve the real-time
