摘要
在线编程 (inapplicationprogramming)是通过微机系统上的I/O口对系统进行编程的方法 ,这种方法给工业仪器仪表中传感器修正系数的更换或监控软件的升级带来了方便 ,特别是对具备远程下载能力的系统 ,其修正系数的更换或是监控程序的升级可以通过通信网络来实现。本文所介绍的是如何在通用单片机为处理器的工业仪器仪表中实现在线编程的方法。
The method of the in application programming (IAP) is the programming method for system via I/O port of microcomputer.It simplifies the adjustment of the sensor’s coefficie nt of process instruments and the procedures of system upgrade. In addition,the adjustment of sensor’s coefficient and system program can also be upgraded via Internet if the system has remote download capability. This article presents how to implement in application programming in common used process instruments.
