Power plant early warning device for defect detection
The granted patent (Publication Number: US11960271B2) discloses an apparatus designed as a power plant early warning device to be installed within a power plant. The device is equipped with a signal measurement unit that receives analog monitoring signals related to the operating states of equipment in the power plant, such as pressure, temperature, and flow data. The signal measurement unit conducts analog-to-digital conversion to transmit digital signals, allowing the device to analyze and quantify the received information to predict potential defects in the equipment's operation. By comparing the final prediction value with actual measurement values, the device can determine if a defect exists and trigger a warning if the residual falls outside the normal range.
Furthermore, the apparatus includes a mechanism to assign ranks to the prediction values based on their reliability, with the highest rank being given the most weight in calculating the final prediction value. The patent also details the use of specific algorithms tailored to each operating state to determine the prediction values, ensuring a comprehensive analysis of the equipment's condition. This innovative approach aims to enhance the early detection of defects in power plant equipment, ultimately improving operational efficiency and reducing the risk of unexpected failures.
