AI Technical Summary

Benefits of technology

This technology helps with accurate measurement for various types of devices used on trains or airplanes during their operations. It includes an acceleration sensors that constantly checks if there're any changes happening around it (their movements). If they don’t go wrong, this will help prevent accidents caused by incorrect movement. Additionally, these technologies have been developed over time due to advancements made within them such as improved tracking algorithms and better data processing techniques. Overall, this technology enhances testing capabilities while reducing errors associated with traditional methods like measuring machine logs.

Problems solved by technology

This patented describes how an electrical train system uses conductors called wires that connect power sources (electric cars) to vehicles for better control over their movement or operation. However, there can also happen issues such as poor connection caused due to factors like rusting or wear from repeated usage. These technical problem addressed in this patents include improving the accuracy and reliability of detecting these physical properties during maintenance operations without requiring multiple manual laborers and reducing human resources required.

Abstract

The invention discloses an overhead line system parameter rapid detection method based on a rail reference mode. Existing track detection and catenary geometric detection are respectively independent detection, and rapid automatic detection of catenary geometric parameters cannot be achieved. Track reference information provided by an inertia track detection trolley is used as a reference source for detecting geometric parameters of the overhead line system, and mileage synchronization triggering information is provided, so that the track geometric parameters and the geometric parameters of the overhead line system can be synchronously detected; the occurring track change angle is provided by an inertial sensor on the inertial track detection trolley. The device has the characteristics of non-contact, real-time detection and good dynamic performance, the testing precision and the working efficiency are greatly improved, the detection equipment is high in centralization degree, convenient to install and wide in application range, and the device has wide application prospects and market value.
