Method and system for monitoring working quality state of track lifting and track lining levelling and tamping vehicle

Abstract

The invention discloses a method for monitoring working quality state of a track lifting and track lining levelling and tamping vehicle. The method comprises the following steps that an operation quantity analog voltage signal from a track lifting and track lining levelling and tamping vehicle simulation control system is collected, the analog voltage signal is converted into a digital signal, andthe digital signal is sent to a monitoring host through a field data bus; a part logic state digital quantity signal entering a program control system of the track lifting and track lining levellingand tamping vehicle is collected, and the digital quantity signal is sent to the monitoring host through the field data bus; an automatic track lifting signal and the like which are output by the program control system and used for controlling the automatic track lifting of a track lifting device enter the monitoring host; the signals are controlled by an emergency stop module and then are transmitted to a track lifting control circuit, a track lining control circuit and other control circuits; and the monitoring host analyzes the collected operation quality state information in real time andsends corresponding alarm information according to different over-proof levels. Compared with the prior art, the operation quality of the tamping vehicle can be monitored in real time, the construction error rate is reduced, and the tamping cost is reduced. The invention further discloses a system for monitoring the operation quality state of the track lifting and track lining levelling and tamping vehicle, and also has the beneficial effects.

Description

technical field [0001] This application relates to the technical field of track construction, and more specifically, to a method for monitoring the working quality status of a lifting and leveling tamping vehicle. In addition, the application also relates to a working quality status of a lifting and leveling tamping vehicle surveillance system. Background technique [0002] In the field of rail transit, a large number of lifting and leveling tamping vehicles are used to maintain and repair railway lines. The main functions of the lifting and leveling tamping vehicle include: lifting operation, adjustment operation, leveling operation and tamping operation. Through these operations, the geometric parameters of the railway line can reach or be as close as possible to the design parameters, and the elasticity or lateral resistance of the railway track bed can be improved to make the train run smoothly and safely. The traditional lifting and leveling tamping vehicle includes a...

Problems solved by technology

Under normal circumstances, the quality indicators of the line after the operation of the leveling and tamping vehicle can be guaranteed, but with the continuous increase in the speed of railway trains, the reliability requirements for the quality of the line after maintenance are also getting higher and higher. , and as a kind of mechanical equipment, the tamping machine may have component failures or mechanical wear or external interference to the control system during long-term operations, resulting in errors in the quality of the work.

In addition, the operation quality of the lifting and leveling tamping truck depends on the operation level of the operator to a certain extent. In the case of unskilled or inattentive operators, it will also lead to deviations in the operation quality. If these deviations are not discovered and corrected in time, it will affect the safety of subsequent train operations
