JP2001039304A - Collecting device of vibration data generated by railway rolling stock in traveling and rolling stock approach warning device using data outputted by this collecting device and rolling stock failure diagnostic device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent the occurence of an accident by announcing the approach of a rolling stock in its early stage to a railway maintenance operator of a railway rolling stock by installing a vibration pickup sensor on a rail by a magnet. SOLUTION: A vibration sensor 32 by a vibration pickup sensor is directly installed on a rail 31 by using a magnet to detect vibration of the rail 31 generated by the arrival of a railway rolling stock by the vibration sensor 32. This detecting signal is sent out to a warning device via a signal wire connected to a connector to actuate a loudspeaker 33 and a warning light 34 of the warning device to give a warning to a railway maintenance operator. Or the detecting signal of the vibration sensor 32 is outputted to a computer of the nearest station monitoring room, a factory car shed and a centralized control room. Thus, by constituting so as to automatically give a warning for the approach of the railway rolling stock by a sound volume and the light, even if there are an oversight and a laspe of memory of a timetable in a commanding supervisor, the warning can be simultaneously given to all the members to prevent the occurrence of an accident.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention contributes to alleviating the occurrence of a collision accident between a railway track maintenance worker and a worker involved in the maintenance of a railway vehicle by utilizing the vibrations of the joints of the rails transmitted along the rails and the rattling generated by the wheels. That is, the abnormality of the vehicle itself is collected and analyzed via the rail as vibration data of the running state and used for failure prediction and failure diagnosis.

[0002]

2. Description of the Related Art As a vehicle approach warning device, there is a device for warning the vehicle approach by a visible sensor.
In the maintenance work involving movement to be installed at a distance of 00 meters, the relocation is continuous and complicated, and there is a plan to install a transmitter at the tip of the vehicle, but this is not realized in terms of cost. In both cases, the reliability is extremely reduced when the vehicle is on a curve or in rain or fog, and malfunctions may occur due to animals or crossing vehicles.

[0003] In the vehicle failure diagnosis apparatus, non-destructive inspection such as an ultrasonic flaw detection test, open inspection of periodic inspection, hammering inspection with a test hammer, and the like are performed on a vehicle in a garage in a halt state. However, no inspection has been conducted on the sound or vibration of all vehicles.

[0004]

The present invention has excellent portability without being affected by weather conditions, physical conditions, and geographical conditions in order to help eliminate accidents that are bounced by vehicles of maintenance workers, especially accidents caused by temporary trains. By developing a device that informs all workers of approaching vehicles that are easy to install at the same time, direct visual and audible recognition of approaching vehicles is very late as the number of accidents tells, and all workers at the site can be confirmed , Especially when approaching vehicles at high speed, claims that the confirmation will be delayed. Greater safety for workers and vehicles.

[0005] Inspection of sound and vibration in the driving state of the vehicle is not performed. Therefore, the vibration of the vehicle moving up and down at a fixed point at almost a constant speed for each passage is collected and analyzed as data to predict failure, diagnose failure, Increase the safe operation of vehicles by referring to inspection and maintenance.

[0006]

In order to achieve the above object, in a vehicle approach warning device, a vibration sensor is directly attached to a rail by a magnet to facilitate attachment / detachment / movement, and a rail joint and a wheel transmitted on the rail. The vibrations of the rattling noise generated from the sound are converted to sound and all the workers are notified at the same time with a speaker and the alarm light is turned on, and it is installed close to the work site, and the weather conditions, physical conditions, geographical location which are weak points of other technologies Conditions were eliminated.

[0007] Another object of the present invention is to provide data that has not been available as reference data for failure prediction, failure diagnosis, abnormality detection, and maintenance inspection. Vibration information of a vehicle device in a continuous driving state is provided and accumulated as data in up and down running at three places of a straight line with the highest speed and right and left curves.

A warning is issued by.

In FIG. 4, a signal from a vibration sensor (36) directly attached to a rail (35) is output to a computer such as a station monitoring room, a factory garage, a central control room, or the like.

[0013]

Since the present invention is configured as described above, it has the following effects.

[0014] The vehicle approach warning device is convenient to carry, can be easily attached and detached and can be moved quickly and easily, and when the vehicle approaches, the volume and light automatically warn the user so that the command supervisor can overlook or forget the timetable. Even if there is, if it is confirmed that the installation is performed securely, an alarm can be issued to all members at the same time, and the safety of the track maintenance worker and the vehicle can be improved.

[0015] In the vehicle failure diagnosis device, the vibration in the driving state of the vehicle is provided as data,
It can be used as a valuable information material for maintenance inspection, failure prediction and failure diagnosis, and can be used for safety management of vehicle equipment.
