The use of robotic in-line inspection supported by a cluster of technologies including robotics design, sensors, scanning, imaging and AI, is an advanced smart solution to our future smart water management. Robotics design: The serpentine type robot manoeuvres through the water mains network and is operated remotely by a trained technician, while the data and commands are transmitted from the robot via a wire. Sensors, scanning, and imaging: The ultrasonic waves mounted on the robot send out different frequency of ultrasonic waves into the inside surfaces of pipe and liners, and receive the ultrasound waveform by the methods of reflection and/or attenuation, to identify flaws and thickness of pipes and liners. The advancement of sensors, scanning and imaging for the acquisition of data would help visualise and understand the pipe problems. Artificial intelligence: The AI-based analysis is used to apply algorithms to sift through the signals and images collected by the sensors and use deep learning algorithms to conduct a centralised processing with more accurate results in a systematic way to understand and digitise the in-situ conditions of pipes. It would help address the pipe problems before they become critical, and contribute to the predictive maintenance to reduce the unplanned shutdown of water supplies. 管道檢測機械人怎樣運作 How In-line Inspection Robot operates 管道檢測機械人能在多個地下環境下，以更短的處理時間，在水管內以 不同角度單向高效地行駛超過 150 米。機械人最高的直線行駛速度為每 秒20 厘米。 Operating under various underground conditions, the In-line Inspection Robot can navigate efficiently along the interior of water mains in different angles in a single pass to reach over a distance of 150 meters with shorter processing time. The maximum linear driving speed of the robot is 20 cm/sec. 數據處理和控制中心收集、儲存、分析、匯報從視 覺檢測相機和超聲波探頭收集所得的數據，並控制 管道檢測機械人的動作。 The Data Processing and Control Unit collects, stores, processes, analyses, and reports the data obtained from the inspection cameras and the ultrasonic probes and controls movement of the in-line inspection robot. 數據處理軟件應用程式分析回流超聲波，以計算管壁的厚度，並分析 所拍攝的影像來指出管道內壁或已出現的缺陷和裂縫。數據處理應用 程式顯示結果後，能讓用戶審閱和篩選資訊來製作報告內容。 The data processing software application analyses the ultrasonic returns to calculate the pipe wall thickness and analyses the photographs taken to highlight possible flaws and cracks on the interior pipe surface. The data processing application then displays to the user results that are out of bounds for review and selection for inclusion in a generated report. 現新 Innovate 水務署 二零二一至二二年年報 WSD Annual Report 2021/22 58
