Description

Data Acquisition Apparatus of High Temperature Components and Control Method Thereof The present invention relates to a data collection device for high-temperature components and a control method thereof. More specifically, the invention relates to a data collection device for high-temperature components and a control method thereof that enables efficient management of high-temperature components by collecting information on turbine blades through a LIDAR (Light Image Detection And Ranging) sensor and RFID (Radio Frequency Identification) and transmitting it to a high-temperature component management system, thereby allowing for real-time location verification of high-temperature components of a power generation gas turbine and linking it with operation and maintenance history. Generally, combined cycle power generation capable of simultaneously producing electricity and heat consists of a gas turbine, a steam turbine, and a heat recovery waste heat boiler. A gas turbine is a rotary power machine that generates combustion gases by burning natural gas in a high-temperature, high-pressure environment and extracts energy from the flow of these combustion gases. A gas turbine includes a compressor, a turbine, and a combustion chamber. Air compressed in the compressor is mixed with fuel and combusted, causing high-temperature, high-pressure gas to expand, and this force is used to drive the turbine. The turbine is located at the rear of the combustor and generates power by rotating through vanes and blades, utilizing the force of the expansion of high-temperature, high-pressure gas. Managing the history of high-temperature components, such as vanes and blades of a gas turbine, from introduction to operation, refurbishment, and disposal is a key part of gas turbine operation. Generally, for the management of high-temperature components, the serial number located in the root area at the bottom of the blade has been manually checked and managed by recording it in an Excel sheet. This method has limitations in data access and real-time management. Since then, there have been attempts to establish and utilize software, such as high-temperature component management systems, for more systematic management. However, even when using such systems, operators face the difficulty of having to manually input a significant portion of data, including the serial numbers, current locations, and operation and maintenance history of each high-temperature component; consequently, most management practices still rely on existing Excel spreadsheets.
