ABSTRACT
GSM is the recent years developed rapidly digital mobile communication networks, using mobile technology to implement remote control has been growing with extensive theoretical and practical aspects of the research value. This article introduces a network based on SMS (Short Message Service) of GSM wireless remote monitoring terminal principle and simplify system design, to achieve the KHF-4 experimental box built by a GSM wireless module (Siemens TC35) and a SCM (AT89C51) as the core of remote monitoring system control module.TC35 send messages to mobile phone users and cell phone users to receive messages. So that it can establish the phone and microprocessor control system for remote communication. SCM control systems use AT commands and wireless communication module TC35 to realize communications, achieving the purpose of the functions of the system.
This thesis discussed the system's hardware elements, and then discussed some of the software and the implementation of the functions.
