[Abstract]:The efficient combustion chamber is the heat source of the closed gas turbine. The purpose of the research is as follows: first, the control law of the high efficiency combustor is studied, and the second is the foundation for the study of the monitoring system of the whole Brayton cycle power plant. The monitoring system adopts the design of embedded control. The system has the characteristics of small volume and light weight. The research contents include: the overall design of high-efficiency combustion chamber monitoring system, the hardware platform based on embedded FPGA controller, and the design of 4-20mA signal processing circuit, temperature signal processing circuit, The software of pulse signal processing circuit and switch signal processing circuit is developed by LabVIEW language, including the design of data acquisition and real-time control program. At the same time, the software of upper computer is designed by Lab VIEW. The research results include a set of hardware equipment with embedded controller as the core, a set of high-efficiency combustion chamber system monitoring software and a set of host computer monitoring software. Finally, the matching test of high efficiency combustion chamber monitoring device is carried out. The experimental results show that the monitoring system has good control effect and can ensure the high efficiency combustor to work normally and meet its performance requirements.
