The dynamic data acquisition instrument ensures the accuracy and stability of the collected axle load and gross weight data in the complex traffic environment, which mainly depends on its advanced technical design and multiple safeguard measures.1. High precision sensorStrain sensor: dynamic data acquisition instrument usually uses high-precision strain sensors to measure the axle weight and total weight of the vehicle. These sensors can accurately sense the tiny strain changes caused by vehicles passing through and convert these changes into electrical signals.Sensor calibration: To ensure the accuracy of the data, the sensor needs to be calibrated regularly. By using a standard weight block for calibration, the drift and error of the sensor can be eliminated to ensure that the data output by the sensor is always accurate.2. Dynamic weighing algorithmReal-time data processing: The dynamic data acquisition instrument has a built-in high-performance processor, which can process the data collected by the sensor in real time. Through the complex dynamic weighing algorithm, the axle weight and total weight of the vehicle can be accurately calculated, and the high accuracy can be maintained even during the movement of the vehicle.Filtering and denoising: In a complex traffic environment, the sensor may be subject to various disturbances (such as vibration, uneven road surface, etc.). The dynamic data acquisition instrument uses digital filtering and denoising techniques to effectively eliminate these interference signals and ensure that the acquired data is clean and stable.3. Multi-sensor fusionMultiple sensors working together: a dynamic data acquisition instrument is usually equipped with multiple sensors distributed in different locations. The accuracy and stability of the data can be improved by multi-sensor data fusion and cooperative work. For example, the data of multiple sensors can be mutually verified and supplemented to reduce the error of a single sensor.Redundancy design: In order to improve the reliability of the system, the dynamic data acquisition instrument adopts redundancy design. Even if one sensor fails, other sensors can still work normally to ensure the continuity and stability of data.4. Environmental adaptabilityAnti-interference design: the design of dynamic data acquisition instrument takes into account the influence of various environmental factors, such as temperature change, humidity, electromagnetic interference, etc. By using anti-interference design and materials, the impact of these environmental factors on data acquisition can be effectively reduced.Structural stability: The mechanical structure of the dynamic data acquisition instrument is designed to be solid and stable, which can withstand the impact and vibration generated when the vehicle passes, and ensure the stability of the sensor and data acquisition system.5. Data verification and validationData verification: The dynamic data acquisition instrument performs multiple checksum verification after data acquisition. By comparing historical data, standard weight data and data from other sensors, the accuracy and consistency of the collected data can be ensured.Automatic diagnosis: dynamic data acquisition instrument has built-in automatic diagnosis function, which can monitor the operation status and data quality of the system in real time. If an abnormal situation is found, the system will automatically alarm and take appropriate measures to ensure the stability of the data.6. Real-time monitoring and feedbackReal-time monitoring: The dynamic data acquisition instrument is equipped with a real-time monitoring system, which can display and record the acquired data in real time. Through the monitoring system, operators can know the status and quality of data acquisition at any time, and find and solve problems in time.Feedback adjustment: according to the real-time monitoring results, the dynamic data acquisition instrument can automatically adjust the data acquisition parameters and algorithms to adapt to different traffic environments and vehicle types to ensure the accuracy and stability of the data.The dynamic data acquisition instrument adopts multiple technical means such as high-precision sensors, dynamic weighing algorithms, multi-sensor fusion, environmental adaptability, data verification and validation, and real-time monitoring and feedback. To ensure the accuracy and stability of the axle load and total weight data collected in the complex and changeable traffic environment.The comprehensive application of these technologies and measures makes dynamic data acquisition instrument a reliable tool in the field of traffic management and vehicle weighing.
