摘要
讨论了Windows98下热敏传感器自动测量控制的实现,设计微机ISA总线测量插卡;运用面向对象的可视化编程工具Delphi和内嵌汇编的方法编写I/O端口的控制函数,实现对I/O端口直接读写操作;采用了防脉冲干扰平均值算法编写二次数字滤波函数,有效去除了工业现场的低频干扰信号。
Presents the implementation of an automatic measurement and control system of the heat sensitive sensor in Windows 98 environment and the design of ISA measuring adapter. With visualized tool - Delphi and embedded assembly language, implemented the control function of I/O port and the read/write operation on I/O port. Using pulse- interfered free algorithm to design twice digital filtering function, eliminated the low frequent interfering signal in the field.
