Description
Technical Field
The invention relates to the field of mechanical detection, in particular to a photoelectric type proximity sensor test bed.
Background
The japanese ohron E2E photoelectric proximity sensor is also called a "proximity switch", and hereinafter referred to as a proximity switch. The speed information of the diesel engine, the transmission case and other parts can be converted into electronic signals under the condition of not contacting with a measuring object, and the electronic signals are fed back to a locomotive microcomputer controller, so that accurate and effective basis is provided for a microcomputer to output correct instructions, and the speed information is widely applied to locomotives for ports such as GK1M, GK1C and the like. However, since the proximity switch is an inlet component, the maintenance personnel does not have relevant technical parameters and maintenance detection schemes. Before loading, the maintainer can not know the performance of the locomotive, when the locomotive is installed on a locomotive for use, a series of electrical and mechanical faults can be caused, and even the hidden danger of major driving accidents such as locomotive breakage, diesel engine 'runaway' and the like can be caused by transmitting error signals. Therefore, in order to ensure the driving safety, operators can consume nearly two ten thousand yuan to completely replace the proximity switch every locomotive overhaul period. In 2016, intermittent auxiliary power generation faults occur in a GK1C 003 locomotive in Dalian gulf, and due to the fact that a proximity switch cannot be tested, a maintainer can only observe the running condition of the locomotive for a long time, and the troubleshooting work lasts for as long as one month.
