A Control System of the Storage for Fresh Commdities by Means of the Combination of a Packet Radio and an Expert System

为了控制新鲜果蔬的贮藏，开发了一种分组无线电和专家系统相结合的系统。分组无线电用于存储或终端与装有专家系统的主机或中心站之间的信息和数据的传输。一套PC9801CV个人计算机和40MB硬盘，一台PC9801CV计算机，终端节点控制器PK-232或TNC-22，肯伍德TH-55收发信机组成分组无线电系统。并发终端软件采用CCT98II。专家系统开发工具采用EXSYS语言，在信息库方面，参考并安装了一系列百科全书式的果树日光病虫害手册(GENSHOKU KAJU BYOCHUGAI HAKKA，Nobunkyo)和蔬菜日光病虫害手册(GENSHOKU YASI BYYOCHUGAI HAKKA，Nobunkyo)。通过连续观察，如果发现任何疾病症状，终端可以访问中心站，通过分组无线电与专家系统进行一系列问答，直到给出最可能的诊断。然后，专家系统会将一系列相关症状系统地发送到诊断中，如果需要，还会发送特征症状的图片。通过对它们的再次确认，最终将检查诊断的概率。疾病的主要原因，应立即进行的对症治疗，明确的疾病建议和严厉的措施将被指导。目前，该专家系统包括叶菜类80多个限定词和功能150条规则，对控制仓储生鲜商品的市场病害是有效的。

A combined system of a packet radio and an expert system has been developed to control the storage for fresh fruits and vegetables. The packet radios are used for the transmission of the information and data between the storage or the terminal stations and the host computer or the central station equipped with the expert system. A set of PC9801CV personal computer and 40MB hard disc, a PC9801CV computer, the terminal node controllers, either PK-232 or TNC-22, Kenwood TH-55 transceivers are used for composing the packet radio system. CCT98II is used for the concurrent terminal software. EXSYS is used for the expert system development tool, and as for the information data base, an encyclopedic series of heliotype disease and pest handbooks for fruit trees (GENSHOKU KAJU BYOCHUGAI HYAKKA, NOBUNKYO) and that for vegetables (GENSHOKU YASAI BYOCHUGAI HYAKKA, NOBUNKYO) are referenced and installed. By continuous observations, if any disease symptom is found, the terminal station can access the central station to make a series of questions and answers with the expert system through the packet radio until the most probable diagnosis will be given. Then, the expert system will send a series of related symptoms to the diagnosis systematically, and if necessary, will send the pictures of the distinctive symptoms. By reconfirmation of them, the probability of the diagnosis will be checked finally. A major cause for the disease, symptomatic treatment which should be done immediately, the definite proposal for the disease and drastic measures will be directed. For the time being, the expert system includes more than 80 qualifier and functions 150 rules for leafy vegetables, and is effective for controlling the market diseases of fresh commodities in the storages.
