With regard to urban increasing traffic congestion problems, an intelligent bus control terminal, which based on embedded system is studied and designed in this paper. It adopts AT91sam 9260 produced by ATMEL company as the processor, realizes positioning information access and completes network data transmission with peripheral GPS and GPRS module. Linux is selected as the operating system, and many advanced technologies such as the linux interrupt handling and multithreading are used in software design process, which bring about high efficiency, less resource consumption, stability and reliability. At the same time, sites and the communication network configuration information are processed by configuration files treatment, convenience for system maintenance in case of modification of later stage circuit, giving full play to the characteristics of embedded system. Compared with similar products, this terminal has advantages with compact structure and low cost. This study provides reference value for the similar product development from software angle, and has great significance.
