The product

At the heart of our revolutionary solution lies the instrumented tensioning weight, which serves as the cornerstone of our technology. This multifunctional weight embodies several key components that work seamlessly together to enable efficient monitoring and data acquisition. Let's delve into the core elements of our instrumented tensioning weight:

1. Inertial Measurement Unit (IMU): The IMU integrated within the tensioning weight employs advanced sensor technology to precisely measure and monitor the weight's acceleration, and vibrations. This crucial data provides valuable insights into the dynamic behavior of the catenary system, facilitating accurate displacement level measurements and enhanced detection of anomalies.
2. Ambient Temperature Sensor: Our instrumented tensioning weight incorporates an ambient temperature sensor that continuously monitors and records temperature variations in the surrounding environment. This information is essential for evaluating the impact of temperature changes on the catenary system's tension and overall performance.
3. Control Unit: The control unit acts as the brain of the instrumented tensioning weight, responsible for processing sensor data, executing algorithms, and coordinating the weight's functions. It ensures efficient and reliable operation, enabling real-time data analysis and immediate response capabilities.
4. Solar Cells & Power Unit: To achieve energy autonomy and minimize maintenance requirements, the tensioning weight is equipped with solar cells that harness solar energy. These cells efficiently convert sunlight into electrical power, which is stored in a power unit, ensuring continuous operation of the weight's functionalities.
5. Communications Unit: Our instrumented tensioning weight incorporates a communications unit that facilitates seamless and secure data transmission. Leveraging wireless technology, the weight transmits collected data to our centralized system through the Low-Power Wide-Area Network (LPWAN), ensuring real-time monitoring and analysis.

By combining these essential components within the instrumented tensioning weight, we have created a robust and intelligent monitoring device. This device not only accurately measures tension levels in real time but also collects valuable environmental data, providing a comprehensive understanding of the catenary system's condition.

Our instrumented tensioning weight's innovative design ensures reliable and autonomous operation, thanks to the integration of solar cells and the power unit. This eliminates the need for frequent battery replacements and minimizes maintenance efforts, resulting in a cost-effective and sustainable solution.

How it works

Our solution incorporates embedded algorithms and an expert system that revolutionize the way railway catenary compensation monitoring is conducted. By analyzing the correlation between ambient temperature and the displacement of the tensioning weight, our advanced system can assess critical aspects of the catenary system's condition. Let's explore the detailed workflow:

1. Data Acquisition: The instrumented tensioning weight collects data using its embedded sensors, including the ambient temperature sensor and the inertial measurement unit (IMU). The IMU captures precise inertial measurements, allowing us to infer the displacement of the tensioning device. These measurements provide valuable insights into the behavior of the catenary system.
2. Ambient Temperature and Displacement Correlation: Our expert system is capable of monitoring the correlation between ambient temperature and the displacement of the tensioning weight over time. By establishing a reference correlation, any deviation from the expected patterns can be identified. This capability enables the detection of subtle changes or irregularities in the catenary system, facilitating early maintenance interventions and minimizing potential risks.

1. Wire Theft or Breaking: Using free fall IMU readings, our system can detect wire theft or breaking incidents. When sudden and significant changes in displacement occur, indicating a weight free-falling, our algorithm raises an immediate alert. This enables prompt actions to mitigate safety hazards and initiate necessary interventions.
2. Entanglement Detection: Erratic up and down IMU readings are indicative of potential entanglement issues. When the displacement data exhibits irregular patterns that deviate from normal behavior, our system promptly identifies these anomalies. This enables quick detection of entanglements, triggering timely interventions to prevent further complications and ensure smooth railway operations.
