摘　　要：在油库罐区自动化系统中,针对监控层过程数据库与管理层关系数据库间通讯问题,提出了采用组态软件专用通讯模块、动态数据交换(DDE)、开放数据库连接(ODBC)等解决方案,重点介绍了一种通过ODBC方式开发的通用数据通讯接口。该通讯接口在多个油库罐区自动化系统得到成功应用,运行效果良好。In the automatic system of the oil tank farm, there was the problem about how to realize data communication between the process database of the supervisory control level and the relative database of the management level. It provided the special module of con- figuration software, dynamic data exchange and open database connectivity methods. A general data communication program, developed with the method of ODBC, was introduced emphatically. The program interface was successfully used in several automatic systems of the oil tank farm, and the effect is very good.
