Working Principle
The over-limit detection system calibration device employs a six-axle articulated combination vehicle as its primary carrier, comprising a tractor unit, a semi-trailer, as well as an axle load simulation device and an external dimension simulation device integrated onto the semi-trailer. The axle load simulation device consists of a movable counterweight loading assembly, a hydraulic pump unit, and position detection and positioning devices. The vehicle and cargo external dimension simulation device mainly comprises five modular groups and external dimension simulation bars. |  |

Advantages and Features
| Feature | Description |
| More Rapid | Capable of performing rapid and synchronized metrological verification and calibration on key equipment in the over-limit detection system, including weighing detection devices and vehicle external dimension detection equipment, without requiring the vehicle to stop, significantly reducing metrological service costs. |
| More Accurate | The original metrological test data is aggregated in real-time to the IoT data platform, enabling timely data processing and issuance of metrological test results, and providing prompt feedback on the accuracy of key equipment parameters within the over-limit detection system, effectively improving equipment operational efficiency and the accuracy of metrological equipment and reducing disputes over data accuracy in over-limit enforcement operations. |
| More Precise | High measurement accuracy. Through scientific system planning and design, combined with high-performance sensors, a high-precision algorithm, and high-speed dedicated data acquisition system, and customized digital signal processing algorithms, the deflection data is ensured to be accurate and reliable. |
| More Safe | The aggregated metrological test data from various over-limit detection systems serves as an integral part of the big data for over-limit enforcement in the transportation industry, ensuring the accuracy and reliability of over-limit detection equipment and providing fundamental scientific data support for industry over-limit enforcement efforts. |
