Description

Technical field:

[0001] The utility model belongs to the technical field of vehicle inspection, and in particular relates to a thermal imaging inspection system for locomotives and vehicles. Background technology:

[0002] In recent years, with the rapid development of the transportation industry, the transportation capacity has been steadily improved, and the number of electrical equipment loaded on locomotives and vehicles has also increased. The daily inspection of the on-board equipment by locomotive and vehicle operators has also become an important means to ensure driving safety.

[0003] The daily duty inspection of the locomotive and vehicle departments is the first checkpoint for feedback of equipment failures. At present, the locomotive and vehicle departments basically rely on infrared temperature guns and temperature sensing stickers pasted near the important distribution devices of the EMU to check the heating of the distribution equipment. The daily inspection methods are relatively simple. Infrared temperature measurement has the disadvantages of small test area and large error (different materials have different infrared reflection effects, and temperature readings are different). In addition, the various functions are not interconnected. The operation records are basically taken by mobile phone photos, and the inspection records cannot be tracked back. The existing on-board inspection equipment and means are increasingly unable to meet the intelligent and fast inspection needs of electrified railways. In addition, the relevant inspection work is becoming increasingly heavy, and the equipment assigned to on-site maintenance personnel is also increasing, which greatly increases the burden on operators. Utility model content:

[0004] The purpose of this utility model is to provide a thermal imaging inspection system for locomotives and vehicles, which can improve the integration of detection equipment and facilitate on-site operations by combining daily inspection work with the handheld terminal of the on-duty personnel.
