【摘要】 针对目前农业气象观测面临的问题,基于虚拟仪器技术对农业气象自动观测进行了初步研究。主要研究成果包括:研制了集采集、传输、处理、分析、存储等一体化,以及可拓展性强的农业气象自动观测原理样机;实现了高清晰嵌入式数码相机的农作物图像的自动采集、编码与实时传输;从原理上实现了应用图像、音频信息进行农作物生长发育状况及自然物候的自动观测;与常规观测方法相比,不仅可以有效增加观测内容,提高观测与服务时效,而且可以大大降低野外工作量和劳动强度,相对减少人力投入,减少人为主观观测误差。该观测技术为农业气象自动化观测系统的进一步研究奠定了基础,并有望改进和提升我国的农业气象自动化观测水平,从而有效增强现代农业气象的业务与服务能力。更多还原

【Abstract】 Aiming at existing problem of agrometeorology observation,a preliminary research was made on agrometeorology automatic observation based on virtual instrument technology.The main contributions included that it had developed the principle prototype of agrometeorology automatic observation,which integrated gathering,transmission,processing,analysis,memory and strong extension.It had realized automatic gathering,code and live transmission for crops image of high clear embedded digital camera.It had realized automatic observation in principle by image and audio information on the crops growth condition and the natural relationship between living things and the seasons.Compared with the conventional method of observation,it not only added the observation content effectively,improve the observation and service timeliness,but it also saved the field work-load and labor intensity significantly,reduced the manpower relatively and people subjective observation error.The observation technology had been laid the foundation for further study for the agrometeorology automatic observation system,and it hopefully made improvement to our country agrometeorology automatic observation,thus enhanced the service’s ability effectively for modern agrometeorology.更多还原
