Research On Grating Digital Readout System Based On Embedded Technology

Embedded system is a kind of special application-oriented computer system. It is based on computer technology and can meet the strict requirement of function, reliability, cost, volume, and power consumption by adjusting its hardware and software. With the rapid development of hardware technology and software technology of computer, embedded-system technology is getting more reliable and perfect day by day. At present, embedded system is widely used in many fields such as industrial control, traffic control, and environment test, etc, because of its high reliability, high performance, and low power consumption and so on.Combined with the research project "development of embedded grating digital readout system SDS5V", this dissertation chooses specific platforms of hardware and software to research and develop the embedded digital readout system on the basis of thorough study of embedded system technology. The kernel of hardware is the 32-bit embedded CPU S3C44BOX with characteristics of high performance and low power consumption. And it is also equipped with the required peripheral modules to extend itself to one whole hardware system. The software system is based on the core of uC/OS-â…¡ real-time embedded operating system, to develop application software which the system needs. This system is not only having advantage of good stability, high reliability and performance, but also is transplantable and trimmed so well as to modify function conveniently according to system requirement. The main researches of the dissertation are as follow:(1) Research on overall scheme of the hardware of grating digital readout system: dividing the hardware module, choosing the hardware platform and internal serial communication method, expanding the outer required modules, and designing the data...
