Motor train set parking contraposition video monitoring system

Abstract

The invention discloses a motor train set stop counterpoint video monitoring system, comprising an image acquisition and processing unit for real-timely monitoring the motion of a maintained motor train set, a monitoring unit embedded with a scale function module and an alarm prompt device controlled by the monitoring unit, wherein the image acquisition and processing system is mounted according to the maintenance position on which a maintained motor train set should stop, the image acquisition and processing system is connected with the monitoring unit connected with at least one user PC, the image acquisition and processing system and the user PC and the user PC are connected and communicated via a wireless network, the scale function module real-timely measures the motion speed of the maintained motor train set and the distance between the maintained wheel of the motor train set and the maintenance position. The invention can accurately display the distance between the maintained wheel of a maintained motor train set and the processing position, via which drivers can park accurately, realize accurate counterpoint of wheels and attain high working efficiency.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video monitoring system for parking alignment of an EMU. Background technique [0002] 2007 is the year when my country's railways plan to run 200km / h EMUs on existing lines. In order to achieve this goal smoothly, it is necessary to ensure that each group of locomotives is kept in good operating condition at all times, which puts forward more requirements for maintenance work. high demands. The EMU runs for 200,000 kilometers and requires a wheel set repair. For 8 short-set EMUs, 32 wheel sets need to be repaired each time. At present, many EMU maintenance depots are not equipped with tractors due to limitations in space and funds during construction. Usually, multiple maintenance positions are set up in one EMU maintenance depot; Wheel running alignment, the alignment accuracy is required to be controlled within 10 centimeters. In actual use, it is found that it is...

AI Technical Summary

Problems solved by technology

In actual use, it is found that it is not easy for the driver to park the EMU within the required 10 cm range by relying on the parking sign on the ground. The actual situation on the ground has not been accurately grasped, nor can it be completely accurately grasped, so in practice, it is often necessary to repeatedly control the vehicle alignment

[0003] In practice, there are two problems in the repeated alignment of control trains: 1. The auxiliary time of turning wheel operation is long, which greatly reduces the operation efficiency; but since the EMUs are usually put into storage at night for maintenance, other primary and secondary maintenance can be normal After the operation is completed, the turnwheel operation is carried out, so the time for the turnwheel operation is very limited, and the operation efficiency becomes an important problem to be solved; 2. The life of the equipment and the machining accuracy are affected, although the parking alignment is within the range of 10 centimeters. It is allowed, but if the edge position is often used, it will cause uneven force on the top wheel swing frame of the turning machine, prone to partial wear, and reduce the life of the equipment. bit is very important
