Remote control terminal based on TC35i (short message service) SMS has multi-functions, such as one-multi control, multi-one control, access authorization, power fail safeguard, auto reply message. The hardware design, software design and control method were introduced in this paper. The test demonstrates that the design is feasible and reliable. The design scheme can be widely used in remote control based on GSM and is an instructive guideline for extending single-chip microcomputer module to access to 3G network.
