Abstract
In recent years, video data acquisition and wireless communication are increasingly applied in the field of intelligent transportation and environmental monitoring due to its promising capability. A design of data acquisition and communication system based on embedded technology is proposed in this paper. The architecture is discussed, and the detailed design of the system is given including hardware and software solution. Chip S3C6410 and DM642 were considered as the core of information acquisition and processing. Acquired data was sent to database server on control center with integrating wireless mobile network (CDMA). Through the main page of the website based on LAMP technology, it can realize the remote access of sensor monitoring data and control the devices on the vehicle. It also supports the query of the historical records and download of the acquisition data to the client according to requests. Experiment results show that the working performance of the system is quite stable and can reach the design requirements in real-time data acquisition and remote control. Furthermore, the system has the characteristics of good expansibility, networking flexibility and low cost. The design gives a new way to collect the video data of environment instead of the traditional way using wires or manually.
