摘要
针对Honeywell PPT压力传感器模拟输出方式需要数据采集设备才能实现与计算机通信,以及其数字输出精度高于模拟输出精度的情况,为了方便快速地实现PPT的工程应用,利用传感器串口通信特性,基于C++Builder编程,设计了简单实用的测控程序;可通过数字的方式完成对压力传感器信号的测量及常用参数的更改,并能图形化显示传感器的实时测量,通过高精度标准压力输出设备测试,该程序响应速度快,测试结果准确,可完全在个人电脑上操作,成本低廉,易于实现。
Abstract ： According to the situation that communication between the PPT and the computer must build by data acquiring equipment, and that the precision of digital output is superior to the precision of analog output. In order to complete the engineering application of PPT easily, based on the character of RS-232 port in Honeywell PPT, this paper provide a measurement and control program using C＋＋ program ruing language. It can measure the pressure and modify the parameter of PPT, and display the pressure data curve in real-time. This program can be easy to carry out on personal computer with low cost.
