用Delphi实现热敏传感器开关特性自动测量软件设计

The Software Degign Using Delphi to Implement the Automatic Measure of the On-off Characteristic of Heat Agile Sensor

用面向对象的可视化编程工具Ｄｅｌｐｈｉ实现Ｗｉｎｄｏｗｓ ９８下自动测量控制系统的程序设计．采用Ｄｅｌｐｈｉ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．

This paper presents the method of using visualization and OO programming tool Delphi to implement the automatic measure and control system in Windows 98 environment. The embedded assembly language of Delphi is used to program the functions to control the I/O ports for accessing the I/O ports directly. To eliminate the disturbance of the low frequency in industrial field, the arithmetic average defended pulse_disturb of twice-numeric filter, is adopted.
