摘要
为改进温室环境管理系统的性能,获取实时动态生成的决策信息,建立了基于作物模型的温室环境管理系统。在借鉴前人先进研究成果的基础上,通过实验建立了简化的温室番茄和黄瓜作物生长模型;其次,通过收集资料和专家经验建立了温室环境管理知识库;最后,应用农业环境实时监测数据,综合利用模型预测和知识推理建立了温室环境管理决策支持系统。通过实际运行表明,系统可实时动态输出室内温度、光照等参数的优化值及其它相关辅助决策信息,通过进一步完善可望取得更好的应用前景。
To improve the performance of the greenhouse environment management system and to be capable of making real-time decision dynamically, the greenhouse environment management system was developed based on crop model. Firstly, a universal simplified crop growth model for greenhouse tomato and cucumber was established both for referring to former research results and validating its parameters with field experiments. Secondly, a knowledge database was es- tablished by collecting information and experience of experts. Finally, a decision support system for greenhouse envi- ronment management was developed by using of real-time data acquired dynamically integrating the technology of model prediction and knowledge reasoning. Through running in the experiment, the system could give out the optimized value of environmental control parameters, such as temperature, light intensity, and other relevant information to support de- cision and management dynamically. It would get better prospect in future as further completion.
