For the frequent occurrence of school bus' accident, a terminal system fur the monitoring and controlling of the school buses was proposed. Tbe system is based on WinCE6.0 with S3C6410 as hardware platform core. For this system, the video can be acquired through USB ports and the live controlling for the driving school buses through wireless network is thus possible, the acceleration detection can be realized by using sensor MMA7361L and microcontroller STC12C5410AD. Once the acceleration lhreshold is set by server, the controlling for the school buses can also be achieved.
