Abstracts: The basic structure and functions of automatic control system of storage and transportation tank farm for petrochemical industry are described. The specified design content and method for tank farm are discussed from the point of engineering design. Inventory statistic and information management are specific issues for tank farm. Suitable automatic instruments and tank data management devices should be equipped to realize calculation of tank capacity to improve control and management for tank farm from the view of engineering design. The communication connection schemes for storage tank liquid level instruments and motor control valves and precautions for communication device configuration are specially introduced, and detail examples of instruments wiring are illustrated. The structure, functions and signals relationship among each constituent part of the production management system for tank farm are expounded. The basic hardware and software equipped for system are listed. The function of each individual software is introduced with combination of actual production operation. The design concepts of following reasonable configuration, multiple functions, distinctive nuance, consideration of control and management for automatic control system and production management system for tank farm are proposed.

Key words:petrochemical tank farm; tank farm automatic control system; storage tank signal communication unit; motor valve communication unit; tank data management unit; tank farm production management system

近年来国内新建的石油化工厂储运罐区的自动化水平已经不仅局限于采用仪表测量加分散型控制系统(DCS)，有些厂家还配有罐区生产管理系统。将罐区的自动控制系统、生产管理系统与工厂信息管理系统结合起来，卓有成效地提高了储运系统的整体自动化水平和管理水平，实现了控制和管理的系统集成、数据共享、功能集成。……
