摘要
计算机对化学实验数据进行实时采集和处理具有效率高和可靠性好等优点 ,以往采用单片机、PLC系统的较多 ,为了改进系统的设计 ,采用自行设计的小信号调理接口板、智能数据采集模块、RS - 485网络与微机连接的硬件设计 ,以及先进的Delphi语言和面向对象的软件开发技术 ,成功地开发出一种通用、任意通道的微机数据采集监测系统。该系统通用性和扩展性好 ,可以进行多通道、远距离的数据采集。系统硬件、软件和网络结构设计灵活 ,功能强大 ,首先在 72 1型分光光度计上得以成功应用 。
A new all purpose multi channel date sampling & monitoring system is developed and successfully applied in the spectrophotometer. This system could carry though multi channel and long distance data sampling and has perfect generalization and expansibility. By using self-designed small signal enlarging circuit, intelligent data sampling module, RS 485 network, Delphi programming language and Object Oriented development, this system has agile design of the hardware, software, the structure of the network and powerful function, and can be applied in many chemistry experiment and scientific research.
