Embedded System Application In Static Pressure Measurement

Due to the high speed development of national rail system, the demand of static measurement instruments grows greater. Static pressure measurement system consists of static pressure signal and data process system, static pressure signal operate on bridge style sensor ,amplified with amplifier, and then convert to digital signal ;while figure and numeric, which people is familiar with , comes out through data process system.In the static pressure measurement system realized by master-slave single chip machine, the main single chip machine in charge of the management of the whole system, while the slave one do exact task, at last realize display and print function with extra device. This master-slave single chip machine static pressure measurement system basically works well, whereas, there exists fault in aspects of power consumption, size, software's structure, extensible ability, user's convenience.This thesis bends itself to the study of embedded system application in static pressure measurement against the fault in static pressure measurement system based master-slave style single chip machine. The target has sufficient thought of system's function, developing ability, power consumption and size requirement with a angle of embedded system application platform, and plan the corresponding module. The hardware system consists of core board and extended board, while the software system is made of loading program, operating system and file system.At last, the ending does some analysis to the result of experiment. The whole system basically reach the desired function, each module operates well and Linux kernel can be loaded and execute greatly. However, windows application and the corresponding driver of each module are not realized. It expects better performance and more application.
