Description

[0001] Technical field: [0002] The invention specifically relates to a logic signal conversion module of an accelerator control system. [0003] Background technique: [0004] At present, as the gas turbines in the institute are used in power generation, combustion drive compressor units and other fields in recent years, higher requirements are put forward for the gas turbine control system. As the core processing module of the speed control of the gas turbine, the principle of PLC is to adopt the operation mode of sequential scanning, so there is a problem of poor real-time signal processing. However, the control accuracy and execution speed of the fuel valve have a great impact on the operation and control effect of the entire gas turbine. [0005] Invention content: [0006] The purpose of the present invention is to provide a logic signal conversion module of the throttle control system in order to overcome the shortcomings of the above-mentioned prior art. The present ...
