3. Kurulum ve Kurulum

3.1 Fiziksel Kurulum

The sensor module features mounting holes designed to fit a standard Lego shaft, allowing for easy integration into various mechanical setups. Ensure the module is securely fastened to prevent movement during operation.

3.2 Kablolama ve Bağlantı

The module operates with a voltage range of 5-24V and its pin levels are compatible with both 3.3V and 5V embedded systems. Connect the module using the provided serial port interface.

The pinout is typically as follows (refer to Figure 1 for visual confirmation):

• VCC: Power supply input (5-24V)
• Yeraltı: Zemin
• A: RS485 A line
• B: RS485 B line

The module communicates using the MODBUS protocol over an RS485 interface, allowing for robust data transmission over distances greater than 10 meters. It supports cascading up to 128 devices.

3.3 İlk Kalibrasyon

Before initial use, it is crucial to calibrate the accelerometer. Ensure the nine-axis sensor is positioned away from any magnetic field interference. Proper calibration helps prevent attitude angle shifts and ensures accurate measurements.

4. Operasyon

The HESUI angle sensor is designed to detect and measure angles. When connected to a compatible system, it counts shaft rotations. A rotation in one direction increases the count, while a change in direction decreases it. The count is relative to the sensor's initial position, which is set to 0 upon initialization and can be programmatically reset.

The module continuously solves and outputs the current real-time motion attitude in dynamic environments. The integrated attitude resolver and Kalman filter algorithm ensure high accuracy and stability.

4.1 Veri Çıkışı

The sensor outputs comprehensive data at a sampling frequency of 200Hz. The data content includes:

• Zaman
• Acceleration (3-dimensional)
• Angular velocity (3-dimensional)
• Angle (3-dimensional)
• Magnetic field (3-dimensional)

4.2 Modbus Haberleşme

Communication with the module is established via the MODBUS protocol over the RS485 interface. Refer to the MODBUS protocol documentation for details on reading and writing data registers to access sensor measurements and configure settings.

5. Bakım

The HESUI sensor module is designed for durability and requires minimal maintenance. To ensure optimal performance and longevity:

• Modülü temiz tutun ve toz ve kalıntılardan uzak tutun.
• Avoid exposing the module to extreme temperatures, humidity, or corrosive environments.
• Tüm bağlantıların güvenli ve hasarsız olduğundan emin olun.
• Periodically check for any physical damage to the casing or wiring.

6. Sorun Giderme

If you encounter issues with the sensor module, consider the following:

• Inaccurate Angle Readings:
  • Ensure the accelerometer has been properly calibrated.
  • Verify that the nine-axis sensor is not subjected to magnetic field interference.
  • Check if the attitude angle has shifted and recalibrate if necessary.
• No Data Output/Communication Issues:
  • Confirm the power supply (5-24V) is correctly connected and within the specified range.
  • Check the serial port connections (VCC, GND, A, B) for proper wiring.
  • Verify that the MODBUS protocol implementation in your system is correct.
  • Ensure the module is not damaged.
• Kararsız Okumalar:
  • Check for excessive vibrations or physical disturbances in the environment.
  • Ensure the module is securely mounted.
