Intelligent Construction & Mining

Stable Tilt Under Heavy Vibration

The Pain Point: "Hydraulic hammer impacts create massive acceleration noise (g-force), causing standard inclinometers to fluctuate wildly."

Static inclinometers fail here. DAISCH Dynamic AHRS sensors use a 6-axis fusion algorithm (EKF) to separate true tilt from vibration noise, ensuring stable bucket positioning even during high-impact operation.

Dynamic Accuracy: 0.25° under vibration
Interface:CAN & CAN-FD (IP67 Rated)

Structural Monitoring & Solar Tracking

Precision Leveling Over Time

The Pain Point: "Slow environmental temperature changes cause zero-point drift, leading to false alarms in safety monitoring systems."

For quasi-static applications, you don't need fast fusion—you need stability. DAISCH Inclinometers feature ultra-low thermal drift and high resolution, perfect for long-term deployment.

Static Accuracy: 0.1° (Gravity Referenced)
Zero Drift: Calibrated Temperature Compensation

AGV Logistics & Mobile Robots

Eliminate "Phantom Tilt" During Braking

The Pain Point: "When an AGV accelerates or stops abruptly, simple accelerometers misinterpret the g-force as a tilt angle (overshoot)."

Our Smart Motion Sensors solve this by fusing Gyroscope data. The algorithm distinguishes between "linear acceleration" and "actual tilt," ensuring your robot doesn't trigger a safety stop falsely during normal operation.

Feature: Acceleration Compensation
Output: Direct Euler Angles (Roll/Pitch/Yaw)

THE DAISCH DIFFERENCE

Why our AHRS holds steady when others drift.

Generic open-source filters fail under high vibration or rapid acceleration. DAISCH sensors run on the proprietary DSX™ Fusion Engine, explicitly tuned for dynamic stability.

DSX™ Fusion Engine

Our non-linear EKF intelligently distinguishes between "Gravity" and "Linear Acceleration," eliminating phantom tilt during AGV braking.

Tech: Acceleration Compensation
Result: No overshoot during stops

Vibration Immunity

We don't just filter data; we clean it. Through hardware dampening and active de-aliasing filters, we reject high-frequency motor noise.

Testing: Verified on Shaker Tables
Spec: Stable under >5g Vibration

Magnetic Rejection

For heading-enabled sensors, our algorithms detect and reject temporary magnetic anomalies to prevent heading jumps.

Feature: Hard/Soft Iron Calibration
Logic: Anomaly Rejection

Engineering FAQ

Technical Decision Guide

Common questions regarding stability, algorithms, and integration boundaries.

Attitude and heading sensors are designed to output stable, usable orientation information directly, such as roll, pitch, and yaw. Compared to IMUs which output acceceralation and angular rate, they eliminate the need for users to:

Develop and tune sensor fusion algorithms (EKF).
Handle temperature drift and long-term bias manually.
Manage real-world effects such as vibration and dynamic motion.

They are particularly suitable for systems where reliable attitude output is required with minimal integration effort.

An Attitude Sensor typically provides full 3D orientation information (Roll, Pitch, Yaw) and fuses gyroscope data, making it suitable for dynamic motion scenarios.

An Inclinometer focuses primarily on measuring tilt angles relative to gravity (Roll, Pitch only) and is optimized for:

Static or quasi-static applications.
High-resolution tilt measurement (e.g., 0.1°).
Structural or machinery inclination monitoring.

The choice depends on whether the application involves dynamic motion or primarily static angle measurement.

DAISCH ensures attitude stability through a rigorous layered approach:

Factory Calibration: Every unit is calibrated across the full operating temperature range (e.g., -40°C to +85°C/105°C).
Compensation Models: Thermal drift models are embedded directly in the sensor firmware.
Robust Fusion: Algorithms specifically designed to reject transient errors.

This approach minimizes drift and performance degradation during continuous operation in real-world environments.

Yes. DAISCH orientation and attitude sensing products provide fused outputs directly, including:

Euler Angles (Roll, Pitch, Yaw)
Angular Rate (Calibrated)
Linear Acceleration (Calibrated)

This allows system integrators to use attitude data immediately without additional algorithm development.

DAISCH attitude sensors are designed to operate reliably under dynamic motion, vibration, and acceleration changes typical of robots, vehicles, and heavy machinery.

For applications with extreme vibration (e.g., Excavator), we recommend our specific "Vibration Rejected" series which utilizes aggressive hardware and software filtering.

Yes. Selected DAISCH products are specifically designed for outdoor and industrial use. Automotive-grade attitude sensors additionally support:

IP67 Waterproof / Dustproof ratings.
12 V / 24 V direct power supply (Vehicle logic).
Robust mechanical housing (Aluminum).

Depending on the product series, supported interfaces include:

Industrial: UART
Automotive/Heavy Duty: CAN / CAN-FD

Integration effort is minimal. We provide:

Sensors with pre-installed DSX™ fusion algorithms.
Standardized DBC files (for CAN) and SDKs.
Evaluation tools (DAISCH DS_RVision) for immediate visualization.

Most engineering teams move from unboxing to streaming valid data in under 15 minutes.

Yes. Our orientation solutions are commonly used in:

Humanoid and quadruped robots (Balance control).
AMR / AGV platforms (Navigation & Safety).
Construction and mining machinery (Chassis leveling).

Some DAISCH attitude sensors are developed using automotive-grade design practices (referencing ISO 26262 standards). However, full suitability for safety-critical applications depends on the specific system architecture.
