[0002] As a vital artery of the national economy, railway transportation is of paramount importance in terms of safety and reliability. To ensure railway transportation safety, it is often necessary to conduct regular inspections and maintenance of railway lines. This typically requires the use of various precision instruments and equipment, such as track inspection instruments, flaw detectors, catenary inspection instruments, and signal analyzers. In addition, staff also need to carry various small tools and equipment, such as flashlights, crowbars, and pickaxes.
