摘　　要：当人们无法在一些危险场所进行现场作业或控制时,智能小车可得到应用。近年来,双音多频信号技术使拨号速率提高,并应用在交互式控制中,更可组成有线或无线的通信系统。考虑到项目要求的实时远程控制和成本等因素,使用基于GSM网络的双音多频信号来控制由步进电机驱动的小车,使小车能被准确和实时地远程控制,进而完成所需的移动任务。When people can not access some dangerous places to work on-site, a smart vehicle can be used in- stead. Recently, Dual Tone Multi-frequency （DTMF） makes out-coming call quicker and it is used in interactive control system, and even in wired or wireless communication systems. With real-time control and low cost require- ments of the project in mind, DTMF based on GSM network is adopted to control a vehicle equipped with stepper- motors. The vehicle can be driven with great precision in real-time and accomplish the required moving task.
