建築工具箱 100 vs House ECG

建築工具箱 100 是為建築、土木、室內與營建現場工作者設計的專業速查工具。 你可以快速進行容積率、面積、長度、重量、混凝土、鋼筋、結構與常用單位換算等日常計算，也能透過法規檢索入口查找建築法、建築技術規則與常用官方資料來源。 主要功能： - 建築與土木常用計算工具 - 容積率、樓地板面積與基地相關速算 - 結構、材料、施工常用輔助工具 - 法規檢索入口與官方網站連結 - 收藏常用工具與本機計算記錄 - 支援完整版解鎖與恢復購買 本 App 適合作為工作現場、事務所、審圖前檢核與日常學習的輔助工具。正式設計、簽證、申請與審查仍應以主管機關最新公告、全國法規資料庫與專業判斷為準。

Every building has its own vibration rhythm. House ECG uses the motion sensors in a dedicated iPhone to observe that rhythm over time—much like a long-term ECG for a house. Mount an iPhone 8 or newer at a fixed structural point, connect continuous power, place the screen face up, and keep House ECG open in the foreground. The app measures motion 50 times per second, establishes an initial reading for that exact installation point, and compares later stable observations with the same point. House ECG includes: - Three-direction vibration measurement, with north–south and east–west directions shown only when the phone's direction reading is reliable. - Welch spectral averaging with Hann windows and 50% overlap to reduce the influence of incidental bumps and noise. - A low-cost continuous watcher that performs fuller analysis only after a candidate vibration is detected. - Local candidate-event history and user labels for earthquake-like events, traffic, machinery, impact, device movement, or unknown events. - On-device SQLite storage for initial readings, history, and raw candidate-event waveforms. - Optional Sign in with Apple for Email notifications; basic monitoring does not require an account. - Optional comparison with the public USGS global earthquake catalog, approximate address, and weather context when an Email notification is requested. - Clear installation guidance and automatic reminders to create a new initial reading after moving, lifting, remounting, rotating, or changing floors. House ECG was conceived by a Taiwan-licensed civil engineer and National Taiwan University graduate who has participated in earthquake-related work since the 1999 Chi-Chi earthquake. The method is grounded in established vibration-analysis practice and is being improved through long-term field testing. Important: House ECG is a change-screening and field-observation tool. It is not a certified seismometer, earthquake early-warning system, structural safety certificate, or substitute for an inspection by a qualified professional. It does not declare a building safe or unsafe.
