摘　　要：常规编写的汇编程序在Netlab无人职守的实验环境下无法胜任程序的下载,根据Netlab单片机实验系统的建设需要,将AT89S52单片机ISP功能的实现方法应用于Netlab单片机实验系统,在控制端采用ISP技术就可使过程大为简化。给出了基于Inter- net的51单片机实验系统的原理框架、ISP下载点的硬件电路图、ISP编程软件的实现方法以及对应的VC++主程序段代码。为远程监控、实验系统开发以及远程智能仪表升级等提供了一种设计思路。The conventional program written in assembly language is unable to be downloaded under Netlab unmanned experimental environment. Based on the requirement of building Netlab single chip computer experimental system, the implementing method of ISP function of AT89S52 single chip computer has been applied in Netlab single chip computer experimental system. It is found that by using ISP technology, at control side, the procedures can be simplified greatly. The principle framework of Internet based 51 single chip computer experimental system, hardware circuit of ISP download site, implementing method of ISP programming software and its relative codes of main program in VC＋＋ are given. A design idea is provided for remote monitor, development of experimental system and remote intelligent instrument upgrade, etc.
