An automatic detection device and method for locomotive screw looseness

Abstract

The invention discloses automatic test equipment for looseness of a screw of a locomotive and an automatic test method. The test equipment comprises a camera, a DSP (Digital Signal Processor), a sound early warning device, a GPRS (General Packet Radio Service) antenna and an SD (Secure Digital) storage card. The shape of the equipment is improved on the basis of a conventional flashlight, wherein the camera is installed at a lamp holder of the flashlight without affecting normal irradiation of a light source of the flashlight, and the DSP, the sound early warning device, the GPRS antenna and the SD storage card are positioned in the flashlight. Through local test and network background linkage, an image identification algorithm is adopted for realizing state identification of a screw looseness-prevention marking, so as to judge whether the screw is loosened, a numbered code corresponding to each screw is identified in a matching way, so that a background manager can intuitively and clearly know the looseness state of each screw through information transmission, the problems of high unreliability, high test leakage and false risk and the like existing in the conventional method completing looseness test of the screw of the current locomotive by depending on human experience are solved, and the scientificity and the intelligentization of the looseness test of the screw of the locomotive are enhanced.

Description

technical field [0001] The invention relates to locomotive screw loosening detection, in particular to an automatic locomotive screw loosening detection device and method. Background technique [0002] Railway transportation is the main artery of the national economy, which bears 60% of the passenger turnover and more than 70% of the cargo turnover in my country. With the rapid development of my country's social economy and vigorously promoted by the state, my country's railway construction has maintained rapid development in recent years, which has brought great convenience to social travel. At the same time, the issue of railway safety has also received much attention. It is closely related to the safety of life and property of the people and the country, and has become the top priority of railway development. Among the inspection and maintenance measures to ensure the safe operation of the railway, the locomotive screw loose inspection is one of the key items. The loosen...

Problems solved by technology

[0004] The object of the present invention is to provide an automatic detection device and method for locomotive screw looseness, which aims to solve the problems of high unreliability and high risk of missed detection and false detection in the traditional method of locomotive screw looseness detection basically relying on manual experience, and improve the accuracy of locomotive screw looseness. The scientificity and intelligence of loose detection, through the linkage of local detection and background transmission, can establish a safety management system for locomotive parts, improve safety management efficiency, reduce the risk of railway transportation accidents caused by locomotive failure, and provide guarantee for the safe operation of railways
