Abstract: Taking further improving the operation efficiency of agricultural automatic irrigation system as the research objective, the layout of its core structural components was selected as the research object, and the high-performance design research was carried out based on the communication control optimization concept. Combined with the design and operation mechanism of automatic irrigation system, from the perspective of communication network architecture stratification, the calculation and processing model of irrigation system parameters was established. Aiming at the optimization of system software control and hardware configuration, irrigation crops were selected for irrigation experiments. The results showed that: the control optimization layout under the communication network architecture concept could achieve the synchronous improvement of the response accuracy and the decision-making accuracy of the irrigation system, and the system operation was stable and effective. Under the correct process monitoring and implementation of irrigation decisions, the irrigation efficiency of the overall system could reach 94.55%, which meet the requirements of intelligent irrigation control design, had good application and promotion value, and would have good enlightenment significance for the improvement of intelligent and accurate irrigation system.
