Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a method for monitoring a trajectory and a moving body that makes it possible to easily detect abnormalities in the trajectory and the moving body.

[Prior art]

In general, in track-type transportation such as railways, based on the idea that transportation services can be provided with sufficient ride comfort as long as the moving body and the track are in good condition, a certain period is decided based on laws and experience, and each part of the moving body and track is Each has been inspected and repaired separately.

In particular, ride comfort is measured using portable sway testers and ride comfort meters as needed on commercial trains, and repairs are carried out on moving vehicles based on periodic measurements in depots.

In addition, the condition of the track is measured several times a year using a track test vehicle equipped with a precision measuring device on a moving body, and the results are reflected in Morikei.

In the conventional method, the moving object and the track are inspected and repaired separately, which tends to be excessive due to the nature of transportation systems. Furthermore, ride comfort, which is an important element of transportation quality, is only managed based on "estimates." Recently, a method called vehicle monitoring has begun to be adopted, so in the future it will be possible to centrally manage ride comfort onboard the vehicle. However, this method only manages each mobile unit formation, and has the drawback that it is difficult to determine whether the problem is caused by a problem in the mobile unit or the track.

[Summary of the invention]

This invention was made with the aim of eliminating the above-mentioned drawbacks, and is intended to transmit vibration information generated in a moving object traveling on a track and traveling point information indicating the position of the moving object from a reference point to a communication line. By transmitting the information to the central processing unit on the ground and monitoring the status of the orbit and moving object from the orbit information, vibration information, and point information indicating the standard status of the orbit stored in the central processing unit,
A method for monitoring orbits and moving bodies that can easily detect abnormalities is provided.

[Embodiments of the invention]

FIG. 1 is a block diagram showing an embodiment of the present invention. In the figure, 1 is a track, 2 is a moving body running on the track 1, and two cars are connected to form one formation.
3 is a vibration sensor mounted on the moving body 2 to detect vibrations generated in the moving body 2; 4 is an on-vehicle monitor device to which the output of the vibration sensor 3 is input; It detects the position and outputs vibration information and travel point information. 5 is an onboard station of a communication device that transmits the output of the onboard monitor device 4, 6 is a control center installed on the ground, and 7 is a central processing unit installed in the control center 6. The track information is stored as track information indicating a standard condition of the track 1, such as the flatness of the track 1 due to straight sections or curved sections. 8 is a ground station of a communication device that transmits information to the central processing unit 7; 9 is an onboard station 5;
This is a communication line connecting the ground station 8 and the ground station 8.

In the trajectory and moving object monitoring method configured as described above, each moving object 2 follows the trajectory 1 at its own speed.
When moving above the moving object 2, it interacts with the trajectory 1.
Since vibration is generated, this vibration is transmitted to the vibration sensor 3.
The vibration information is continuously measured and transmitted to the on-vehicle monitor device 4 as vibration information. The on-board monitor device 4 detects the running position of the moving object 2, that is, the point information on the track 1, with a predetermined accuracy, for example, within 10M, and transmits the vibration information and the running point information to the on-board station 5. As a result, the status information at the traveling point of the mobile body 2 is transmitted from the on-board station 5 to the ground station 8 via the communication line 9, and is sent to the central processing unit 7. The central processing unit 7 compares the information sent from the moving body 2 with the stored route information and determines the status of the track 1 and the moving body 2.

The state judgment of the track 1 and the moving object 2 by the central processing unit 7 is such that, for example, if a partial bend or road defect occurs in the track 1, the moving objects 2 passing sequentially are different from the normal track 1 section. vibration occurs,
Vibration information is transmitted together with point information. Therefore, since abnormal vibration information is transmitted at almost the same point, it is determined that orbit 1 is abnormal.

Also, by detecting an abnormality in information transmitted from a specific moving object 2 among the plurality of moving objects 2 traveling on the track 1, it is determined that the moving object 2 is abnormal.

〔Effect of the invention〕

As explained above, this invention transmits the vibrations generated in a moving object traveling on a track and information on the traveling point via a communication line to a central processing unit installed in a management center, thereby allowing interaction between the track and the moving object. By analyzing the effects, it is possible to understand the location where vibrations and oscillations occur in the moving body in real time when the moving body is traveling. This is effective in ensuring safety as defects that affect driving safety can be detected in advance, and defects caused by ride comfort can be appropriately repaired when driving is stopped at night. In addition, defective parts of the track can be identified with high precision, allowing for appropriate repairs.

In this way, inspections and repairs that conventionally had to be carried out somewhat excessively to ensure safety can be appropriately carried out, thereby reducing maintenance costs for track-type transportation.
