Design Of Embedded Vehicle Terminal System Based on µC/OS-II

A vehicle terminal monitoring system based on GPRS and GPS is designed to meet the demand of real time and multitask. The hardware design method is introduced with S3C44BOX.Software structure, application multitasks and priority are designed based on μ C/OS-II. The communication and synchronization methods are introduced emphatically with semaphores, mailboxes and event flags group.The test shows the system can run stably and reliably and achieve real-time vehicle monitoring.The design method has reference significance for embedded system development application.
