多重伝送とマイクロ・プロセッサによる冷凍コンテナ監視装置の開発

抄録

Because of recent increasing tendency of refrigerating containers and customer's high specification for refrigerating containers monitoring system, following disadvantages are considered in existing monitoring system which provides one announciator unit for each refrigerating container. 1) The size of monitoring panel is getting bigger as quantity of refrigerating containers increases. 2) A large amount of cables is needed between refrigerating containers and monitoring panel. 3) Price of monitoring system is becoming higher in proportion to refrigerating containers quantity. Therefore the authors have decided to adopt micro processor for monitoring system to make the function more efficient and to satisfy customer's requirements and also have studied to apply multi-data transmission system which was developed two years ago to decrease total cable length onboard. In this paper, summary of new monitoring system and application problems of multi-data transmission system onboard are described.
