Based On The Design And Realization Of Embedded Linux Mtu

This paper is based on the design and implementation of a high speed data Auto acquisition system for wireless net optimize with PC/104 system and real-time operating system Montavista Linux. The difficulty of implementing such a system lies in that the data must be saved to disk as soon as possible while the data acquisition is in process, the magnanimity date must be transferred back to control center and the whole system have to be placed in a very small space. As a result, the data acquisition system must be an embedded real time system.Firstly, in this paper the concept of the embedded real-time system is introduced, secondly its developing processes, current circumstances and future perspectives are analyzed, finally, the design idea of adopting PC/104 system as the hardware platform and adopting DevRocke as the software developed platform is presented.For the difficulty of long distance control and measurement data transmission of traditional mobile data-collector, a new mobile data collector mode is presented based on the embedded Linux system combined with GPRS. The experimental results show that the new method for long distance control and data transmission is very effective.The data structure, software and applicational program of mobile test plat are researched ,meanwhile the realization of the simplified mobile test plat is declared completely.
