摘要
PowerBuilder是目前公认的较好的数据库开发环境，但与其他的数据库开发环境类似，PowerBuilder存在对硬件控制能力差、实时性差的问题，本文介绍一种用Delphi编写动态连接库，与PowerBuilder相结合实现用串口进行多点循控的方法，用该方法我们在齐鲁电视台设备管理系统中实现了一对三十点的循回控制。
PowerBuilder is generally considered one of the best developing environment databases now, and it is similar to the other environment databases. But there is a problem it has less control of hardware and real-time. This article will introduce the Delphi dynamic link-base to you that is united with the method of using serial to realize the multi-dots cyclical control. By using this, the equipment management system of our QILu TV Station has realized 1 to 30 cyclical controls.
