Design And Application Of Industrial Control Platform Based On Pc/104 And Arm

PC/104 bus is a kind of industrial control bus specifically defined for embedded control systems, and has been widely used in the field of industrial control. In this thesis, we studied the development and design of ARM7 common control platform based on PC/104 architecture.The thesis describes the applications and general development of PC/104 in the field of embedded control system and analysis the advantages and disadvantages of current PC/104 main broad module. Then considering wide use of ARM processors now in embedded field, the thesis brought forward the idea that embedded ARM processor would be used in PC/104 board module, and then analyzed its advantages.According to the actual needs of application, this thesis analyzed structural features of ARM7 processor STR710FZ based on ARM7TDMI core the interface techniques, and discussed the key technologies of the module, such as system architecture design, expansion interfaces, storage interfaces and power supply design. Particularly according to the PC/104 bus-specific norms and analysis of STR710FZ bus timing, we used CPLD timing to achieve compatibility between the PC/104 bus and ARM processor, and had reasonable and compatible design of this two. To verify the reliability and practicality of the platform, besides the PC/104 core module, we designed a data collection board based on PC/104 bus standards and then conducted a test. In the software design, the thesis conducted a detailed analysis of industrial control platform software. Specifically we discussed its design idea and the overall framework. Besides, we transplanted theμCLinux operation system to the STR710FZ. The thesis described the process of entire transplantation and design steps in detail. At the same time, we built a test platform for the PC/104 module, designed the test program underμCLinux operation system, and discussed the real-time analysis forμCLinux operation system. Lastly, the thesis provided an application example of the platform-- used in a Dam Security Monitoring System. The experiments proved that the use of ARM processor in PC/104 board module can greatly compensate the shortage of current PC/104 module in practical application, such as power consumption.This embedded control platform combined the advantages of PC/104 architecture and ARM processor, has some innovative. The module's real-time, reliability and scalability can meet the requirements of the task splendidly.
