In irrigated areas, the intelligent management and scientific decision-making of agricultural irrigation are premised on the accurate estimation of the ecological water demand for different crops under different spatiotemporal conditions. However, the existing estimation methods are blind, slow, or inaccurate, compared with the index values of the water demand collected in real time from irrigated areas. To solve the problem, this paper innovatively introduces the spatiotemporal features of ecological water demand to the forecast of future water demand by integrating an artificial neural network (ANN) for water demand prediction with the prediction indices of water demand. Firstly, the ecological water demand for agricultural irrigation of crops was calculated, and a radial basis function neural network (RBFNN) was constructed for predicting the water demand of agricultural irrigation. On this basis, an intelligent control strategy was presented for agricultural irrigation based on water demand prediction. The structure of the intelligent control system was fully clarified, and the main program was designed in detail. The proposed model was proved effective through experiments.
在灌溉地区,农业灌溉的智能管理和科学决策是以不同时空条件下不同作物的生态需水的准确估算为前提的。然而,与从灌区实时采集的需水指标值相比,现有的估算方法存在盲目性、缓慢或不准确等问题。为了解决这个问题,本文创新性地将生态需水的时空特征引入到基于人工神经网络(ANN)的需水预测中,将需水预测指标与需水预测相结合。首先,计算了农作物的农业灌溉生态需水,并构建了一个用于预测农业灌溉需水的径向基函数神经网络(RBFNN)。在此基础上,提出了一种基于需水预测的农业灌溉智能控制策略。充分阐明了智能控制系统的结构,详细设计了主程序。通过实验证明了所提出的模型是有效的。
