Description

Technical Field

[0001] The utility model belongs to the field of rail transportation, and in particular relates to a portable rapid detection device. Background Art

[0002] Urban rail transit is the backbone of urban public transportation. It is energy-saving, land-saving, large-capacity, all-weather, pollution-free, and safe. It is a green and environmentally friendly transportation system. Urban rail transit is a vehicle transportation system that uses rail structures for load-bearing and guidance. According to the requirements of the overall urban transportation plan, a fully or partially enclosed dedicated rail line is set up to transport a considerable amount of passenger traffic in the form of trains or single vehicles. Therefore, the rail transit local control box (LCB) came into being.

[0003] The local control box can isolate the door machine system from other door machine systems when a single sliding door fails. It can issue door opening and closing commands to the DCU on site without affecting the operation of other door machine systems, making it easier to repair and maintain. However, when performing functional tests on each local control box, the test equipment needs to be installed in the on-site door machine system or the LCB needs to be disassembled before using a multimeter to test each contact. It is difficult for the needle-type probe of the multimeter to accurately contact the terminal contacts of the LCB, resulting in measurement errors. Manual testing of each contact will also lead to low work efficiency, slow measurement speed, and non-intuitive results.

[0004] Currently, no portable rapid detection tool is found to be specifically for functional testing of LCB.

[0005] Based on the above, this application provides a technical solution to solve the above technical problems. Utility Model Content
