摘要
在遥测系统运行过程中,用户为了维护方便,要求现地装置除了支持基本的自报、校时、招测、参数修改、远程控制等功能外,也需要支持程序远程在线更新。该文详细介绍了一种基于GPRS无线信道的程序在线更新方法,该方法带补包机制和自校验功能,在确保原系统稳定可靠运行的基础上实现程序在线更新。
In the process of telemetry system operation,in order to maintain conveniently,users require local devices to support not only basic functions such as self-report,timing,recruitment,parameter modification and remote control,but also remote online updating of programs.In this paper,an online program update method based on GPRS wireless channel is introduced in detail.This method has the function of packet-filling mechanism and self-checking,and realizes the online program update on the basis of ensuring the stable and reliable operation of the original system.
