System for Controlling Crop Cultivation Via Telecommunication

在日本进行的防沙治沙和沙漠地区农业调查中，最重要的问题是沙漠是否紧密存在。本课题正是为解决这一问题而开展的，是探索一种利用普通电信线路静态图像和信息通信技术的新方法的基础性研究。“研究智能系统”用于远程信息的通信，亚利桑那大学是农作物种植地，鸟取大学干旱土地研究中心负责信息的传输。研究智能系统概述本系统可以通过普通通信线路获取远程的静态图像和信息。该系统由静止摄像机、静止图像、收发器、静止录像机和监控电视组成。该系统具有图像质量好、时间短（2分钟以内）、普通电信、多线路（ATT、KDD、NTT）使用的特点。1)作物生长诊断所需智能及实际应用研究(1)荒漠地区适应性研究正常拍照无问题，微拍照需考虑相机固定，高温对图像质量无不良影响。(2)亚利桑那大学电信线路图像的传输质量、所需时间和状态与国内图像相当。转移所需的时间是1分50秒。总结了在沙漠地区使用静止相机的方法。2)作物栽培试验本研究是在短期估计的情况下进行的。但是，研究的目的究竟达到了什么程度呢？因为培育成功了。虽然存在一些有待研究的问题，但也表明了该系统的有效性。美国亚利桑那大学的研究人员指出这一系统在发达国家向发展中国家转让作物种植技术方面最为有效。2)如果系统用于教育，则图像和信息为实时文本。关于在沙漠地区使用该系统的问题在本研究中不存在这个问题。但对于硬性质的通信，必须研究粉尘、温度、电源和通信线路的预防。少

Most important problem on investigations in Japan for prevention of desertificarion and agriculture in desert area are which desert does not exist closely. This study was carried out for solution of this problem, and was a fundamental research to fumble for a new method using technology on communication of still image and information by ordinary telecommunication line. "Research Intelligent System" was used on communication of information from distant place, University of Arizona was place for crop cultivation, and Arid Land Research Center, Tottori University took charge of transmission of message.1. Outline of Research Intelligent SystemThis system could get still image and information from remote place with ordinary telecommunication line. This system was constructed with still camera, still image, transceiver, still video recorder and monitor TV. This system had character which quality of image was very fine, time required is short (within 2 minutes) and ordinary telecommunication … More line (ATT, KDD, NTT) used.2. Results in the Current Year1) Study of Necessary Intelligence for Growth Diagnosis of Crop and Practical Use (1) Study of Adaptability on Desert AreaThere was no problem on normal taking a picture, but fixation of camera was necessary was considered on micro taking, And there was no bad influence to quality of image by high temperature.(2) Quality of Transfered Image, Time Required and Status of Telecommunication LineImage from University of Arizona was as fine as domestic image. And time required for transfer was a minute and 50 seconds. Above, using still camera in desert area was concluded.2) Experiment of Crop Cultivation This research was carried out in short term above circumstances of estimate. But it was considered which aim of this research was achieved. Because cultivation succeeded.Although it existed which problem must be studied, effectivity of this system was indicated.3. Indication by Researcher in University of Arizona1) This system is most effective on transfer of crop cultivation technique from advanced countries to developing countries.2) If the system is used on education, image and information are live text.4. About Problem to Use This System on Desert AreaOn this study problem did not exist. But on correspondence in hard nature, prevention of dust, temperature, power supply and telecommunication line must be studied. Less
