Method and system for monitoring height changes of compensation pendant of contacting net

Abstract

The invention discloses a method and a system for monitoring the height changes of a compensation pendant of a contacting net. The method comprises the following steps that S01, fault modeling, a specialty that the fault modeling of a compensation device is established by analyzing the vertical-and-horizontal or multi-dimension big data according to the big data of the height of the pendant; S02, data collecting, a specialty that the height of the pendant and the scene temperature and light are detected and sent to a control center; S03, data processing, a specialty that the fault modeling is matched according to the data of the scene temperature and light and the height of the pendant; S04, fault warning, a specialty that the corresponding fault modeling warning is made according to the matched fault modeling of the step S03; and S05, fault processing, a specialty that the corresponding fault removing is performed according to the fault judgment in step S04. According to the method, the fault modeling of the compensation device is established according to the state of the pendant, and then the matching with the fault modeling is conducted according to the actual detected pendant state, so that the working state of the compensation device is known accurately. The whole process does not need the manual participation, and the workload is reduced.

Description

technical field [0001] The invention relates to the field of monitoring of catenary compensation devices, in particular to a method and system for monitoring changes in the height of catenary compensation fall. Background technique [0002] The operating state of the catenary compensation device is affected by construction quality, maintenance investment, environmental changes, etc., and it is prone to failure, such as: the tilt of the movable pulley and the partial wear of the compensation rope, the friction between the anchor compensation rope and the double-ring rod of the line anchor, and the failure of the weight and hoop It plays a fixed role, and the fixed bolts of the pulley on the bridge and other places with large vibrations are loose, and the fault of the compensation rope falling out of the groove may occur, and various faults are directly reflected in the sudden change of the position of the compensation weight, so the continuous observation of the compensation w...

Problems solved by technology

[0003] The disadvantage of the prior art is that the compensator relies on the gravity of the pendant string to keep the tension of the thread in balance

When the temperature changes, the expansion and contraction of the thread makes the pendant string rise and fall. When the pendant string rises and falls beyond the allowable range, if it falls too much, the bottom surface of the pendant string will touch the ground or if it rises too much, the earring hole of the pendant will be stuck on the fixed pulley. slot, the compensator will lose its compensating effect

However, the current operating status of the catenary compensation device needs to be measured and determined manually, which cannot achieve real-time analysis and early warning of big data, and also consumes a lot of manpower
