The 3D Attitude Monitor is a professional monitoring solution that combines IoT hardware with a 3D desktop visualization host application. This system is specifically designed for long-term tilt and attitude monitoring of rod-like or tower-like structures such as lightning rods, tall towers, and bridges. It collects data through a high-precision MEMS sensor at the front end and performs real-time 3D model reconstruction and smooth display on the computer, helping users to intuitively grasp the health status of the structure.
Figure 1: System Overall Architecture Diagram
- Real-time 3D Attitude Visualization: Converts raw angle data into an intuitive 3D "lightning rod" model based on underlying mathematical matrix transformations.
- Industrial-Grade Anti-Jitter Algorithm: Built-in Exponential Moving Average (EMA) low-pass filter and an advanced Deadzone filtering algorithm completely eliminate environmental sensor noise, resulting in a rock-steady display.
- Multi-dimensional Data Synchronization: In addition to X/Y axis tilt angles (Roll/Pitch), it simultaneously monitors the structure's total acceleration (Total Acc) and ambient temperature (Temp).
- One-Click Reference Plane Calibration: Supports dynamic calibration of a relative zero point and restoration of the absolute physical gravity reference.
- Highly Customizable (White-labeling): Allows for no-code modification of the software title and button text via an external configuration file, and enables one-click replacement of the company logo.
- Applicable Hardware: ESP32 series main controller + LIS3DH 3-axis accelerometer/temperature sensor
- Communication Interface: USB to Serial (Default Baud Rate: 115200)
- Host PC Environment: Windows 10/11 (Standalone version, no Python dependencies required)
- Attitude Refresh Rate: ~50Hz (20ms interval, extremely fast response)
- Algorithm Deadzone Thresholds: Angle 0.6° / Acceleration 0.02G / Temperature 0.2°C (The underlying algorithm is encrypted for excellent anti-interference performance)
