And due to the nature of the data acquisition, three data acquisition circuit board are adopted. They are voltage to digit data converting circuit board, current to digit data converting circuit board and digit data input/output circuit board. These circuit boards are used to acquire the main running parameter of the multifunctional experimentation equipment and to control the output of alarm message.The monitor and control program is developed on Delphi5.0 which is an excellent product of Borland Corp.

数据监控系统的硬件以一台工业控制PC机为核心，并根据采集信号的性质配置了电压-数字量转换板、电流-数字量转换板及开关量输入／输出板，对实验台的主要运行参数进行采集并进行报警控制；监控系统的软件以BORLAND公司的Delphi5.0作为开发平台，采用了面向对象的设计方法，运用了多线程、数据库等技术，做到了界面美观、操作方便。
