Abstract The union of communication and auto control technology brings remote data transmission technology，it is hot spot present.When Remote Monitoring syst臼n，as the ∞re of remote data transmission ，is used in traffic，electric pow町 industry agriculture， irrigation works，environment protection ，construction ，and energy which required nobody monitor and defend，the sup町vised objects s叩arate in distant extension，even the lineate net is lacked. The transmission data is paroxysmal and limited. Traditional r臼note monitoring technology access Internet based on Scene-bus，it requires build local area network platform and remote monitoring syst臼n in access end. This system is dependent on environment v町y much，easily to cause region limitation. The artic1e encompassment the mode of wireless data transmission ，introduced the development and latest situation of wireless data transmission in China and foreign. Futhermore，by research and the discussion to 由e GSM short message in the remote data transmission application，this pap町 have showed the terminal solution of GSM/SMS wireless，also focused on exploiture approach and exploiture process. Aim to the little_data transmission ，it brought a point of view that using the short m臼sage as the data transmission carri町 analysing the structure of the commnuication protocol and the process of the shot message receiving and sending. Then，combined the wireless data transmission technology with the car al町m syst臼n，it describes the detail design process of car al缸m syst田n based on GS岛lISMS wireless data transmission which micro processorμPSD and wireless communication module TC35i on board. In the train of this pap町 implementation procedure of the c缸 al缸m syst臼n was described ， including hardware modules design principle and circuit sch臼natic diagram. Finally，it points out the insufficiency of this article and the aspects which need to improve. Research the essential technology and protocol of GSM. Design
