[Abstract]:With the rapid development of computer technology and electronic information technology, the design level of embedded system at chip level and system level is becoming higher and higher, and the function of embedded system is becoming more and more powerful. Its main microprocessor is the newest Cortex series microprocessor designed by ARM, the operating system is embedded Linux,Wince and uCOS and so on. The design concept of embedded system has been widely studied and applied in many fields such as communication and instrument. The embedded system is designed for different application purposes. In the research of the subject, a design scheme of embedded master-slave computer system based on USB communication is put forward, which combines the embedded system with more and more mature and universal serial bus (USB) communication technology, and it is applied to the design of landslide monitoring system. The main research work is as follows. Firstly, the background and significance of the research are analyzed, the current situation of embedded system is summarized, and the research problem is introduced. According to the research status of embedded system, the transmission process of USB is analyzed, and the overall design scheme of embedded master-slave system based on USB communication is put forward. Secondly, on the basis of the overall design scheme, the system hardware architecture and software architecture are analyzed and designed, and the hardware and software system platform is customized. Considering the compatibility and speed of the extension, a high-speed USB data transmission scheme is introduced in the design of data transmission, and the key modules of the USB communication system of the master-slave computer are designed. Then, based on the study of the USB subsystem architecture of the Linux kernel, the design of the USB device driver and the USB firmware program on the microcontroller is carried out, and the relevant development and testing work is carried out. Finally, under the design idea of embedded master-slave computer system based on USB communication, it is applied to the design of landslide monitoring system, and relevant testing work is carried out, which meets the requirements of engineering design in terms of stability and accuracy.
