Problems solved by technology

However, the hydraulic switch machine moves quickly, and it is difficult to obtain accurate data from the actual measurement of the oil pressure gauge. Moreover, due to the influence of factors such as the level of testers, the accuracy of the oil pressure gauge, and weather conditions, the test data is easily distorted, so it cannot reflect the oil pressure in time. Due to changes in the situation, it is impossible to find out whether the switch machine is leaking oil in time

Abstract

The invention relates to operation state online automatic detection control method of hydraulic goat railroad switch, and relative device, which is formed by a pressure sensor, a embedded microprocessor control module, a A / D conversion module, a serial port communication module, a storage module, and the detecting software of PC machine. It is characterized in that: it uses the system of upper and lower machines, while the upper machine and several lower machines can realize the distributed data collection and detection via bus; and via the detecting software and separation protection device can form, it can form a hydraulic goat railroad switch with self-maintenance ability, anti-disturb ability and lower energy consumption. And it can alarm real time and inquire and analyze history data.

Description

technical field [0001] The invention belongs to the field of railway signal acquisition and monitoring, in particular to an online automatic measurement and control method and device for the running state of a hydraulic switch machine turnout. Background technique [0002] The turnout is located at the combination of rails to realize the movement and connection of rails. The action of the switch is completed by the switch machine. Because the turnout is in the open air, it is prone to rust, debris blockage and other accidents, resulting in misoperation, non-operation, incomplete operation of the turnout, causing major traffic accidents, especially on quasi-high-speed trains up to 200km / h At the same time, due to the high traffic density and the large number of turnouts and switch machines (there are dozens of small stations and hundreds of large stations), it is difficult to strictly guarantee it only by traditional regular preventive tests and regul...
