[Abstract]:In thermal power generation and nuclear power generation, most of them are driven by steam turbine generators to produce electric energy. If the turbine generator sets fail, it will cause huge economic losses and serious social impact. The condition monitoring system of turbine-generator set is the key equipment to monitor and protect the safe operation of turbine-generator set. Based on the state monitoring and fault diagnosis technology and its system research of ultra supercritical large turbogenerator set, the status monitoring system of turbogenerator set at home and abroad has been investigated extensively, and the technology at home and abroad has been deeply studied and analyzed. This paper points out the problems existing in the current condition monitoring system and, aiming at these problems, develops the research work of the condition monitoring system of the turbogenerator set based on the embedded system. In this paper, a design scheme of the condition monitoring system of turbogenerator set based on ARM and Linux is proposed. The embedded Linux operating system is studied and transplanted. The system application program with perfect function is written, and a set of perfect functions is developed. The high stability embedded turbogenerator condition monitoring system solves the problems existing in the current condition monitoring system and has important application significance. The main contents and chapters of this paper are as follows:. The first chapter summarizes the status quo and development trend of turbogenerator unit condition monitoring system at home and abroad, and introduces the embedded system and its application in the turbine generator unit condition monitoring system. The problems existing in the embedded turbogenerator condition monitoring system are analyzed. Finally, the main research contents and the overall framework of this paper are put forward in combination with the research proposition. In the second chapter, the condition monitoring system of turbogenerator is summarized. According to the demand of industrial field and the developing trend of the condition monitoring system of turbine generator set, the design goal of this system is put forward, and the system is studied and analyzed. A design scheme of turbine generator unit condition monitoring system based on ARM and Linux is proposed, which provides the theoretical basis for the next work of this paper. The third chapter introduces the ARM processor. Combining with the system design goal, the embedded industrial control motherboard is investigated and selected. Finally, the storage space of the industrial control motherboard is allocated in combination with the software design scheme and the characteristics of the industrial control motherboard. Prepare for the transplant of embedded operating system. Chapter 4th studies the embedded Linux operating system. On this basis, the transplant of embedded Linux operating system is completed. Finally, the performance of the embedded platform is evaluated. The results show that the embedded platform meets the design requirements of this system. In chapter 5th, according to the design goal of this system, the function of the application program of the embedded turbogenerator unit condition monitoring system is subdivided, the implementation scheme of the application program is studied, and the development tool of the application program is selected. The application program with perfect function has been developed. The test and analysis results of 6th chapter show that the system solves the problems of limited function and low efficiency in the current embedded turbogenerator unit condition monitoring system, and the effect is remarkable. It has important application significance. Chapter 7th summarizes the research and development work of the full text, and puts forward the prospects and suggestions for the following research and development work.
