With the popularization of the mobile phone, espe- cially of the short message, it is capable to control the elect- rical appliances through the technology of short message rec- eiving and sending away from home. What’s more, it can avoid the malpractice of the traditional wired transmission as well as the situation that the line is unable to put through in the emergency case. Therefore using the existing GSM network resources, giving play to its high network coverage and the character of good transmission, provides a convenient way of wireless data transmission for us, it must be the tendency of the long-distance detecting and control domain. This design introduces a system of long-distance electri- cal appliances based on GSM network and the ARM processor. This is a new application in the long-distance control domain through the GSM network and embedded system. We apply LPC2131 chip, which supports the simulation of real time and the embedded tracking as the ARM micro-proc- essor, it is a ARM7TDMI-S CPU of 16/32 bit with high speed and low power consumption. The ARM processor samples, an- alyses, and deals with the short message that the GSM module has received. And the
