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

本文介绍了一种由分组无线电和专家系统组成的果蔬保鲜贮藏控制系统。分组无线电用于在存储器或终端站与主计算机或配备有专家系统的中心站之间传输信息和数据。该系统由PC 9801 CV个人计算机和40 MB硬盘、PC 9801 CV计算机、PK-232或TNC-22终端节点控制器、Kenwood TH-55收发机组成。并发终端软件采用CCT 98 Ⅱ。专家系统开发工具使用EXPERT，信息数据库参照并安装了果树的日型病虫害手册（GENSHOKU KAJU BYOCHUGAI HYAKKA，NOBUNKYO）和蔬菜的日型病虫害手册（GENSHOKU YASAI BYOCHUGAI HYAKKA，NOBUNKYO）。通过连续观察，如果发现任何疾病症状，终端站可以通过分组无线电接入中心站，与专家系统进行一系列问答，直到给出最可能的诊断。然后，专家系统将系统地发送一系列相关症状进行诊断，如果需要，将发送特征性症状的图片。通过对它们的再次确认，最终检验诊断的可能性。对本病的主要病因，应立即进行对症治疗，明确提出针对本病的治疗方案和严厉措施。目前，该专家系统包括80多个叶菜类商品的鉴定词和150多条叶菜类商品的功能规则，可有效地控制仓储生鲜商品的市场病害。

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.
