Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a train operation control system that transmits weather conditions such as rain and strong winds from a ground operation control system to the train and allows the train to run according to the weather conditions on the train. It relates to a train operation control system that enables safe and reliable train running.

[Conventional technology]

In conventional train speed control systems, weather conditions had to be entered manually from the control panel of the traffic management system. In addition, only acceleration and deceleration were corrected depending on weather conditions. However, it did not include a method for automatically detecting weather conditions and instructing trains to run, and a control method for limiting the maximum speed between stations. Furthermore, the line-wide directives did not address the need to carry out controls tailored to the actual situation in each region along the route.

[Problem that the invention seeks to solve]

The above-mentioned conventional technology does not take into consideration the method of automatically detecting weather conditions and issuing commands for train running, and the control that limits the maximum speed between stations, and requires humans (commands) to make decisions and input. However, there are problems with this method, such as delays in noticing changes in weather conditions, and the inability to determine weather conditions in sections far from the dispatcher. Ta. In addition, in the case of strong winds, it is necessary for the train to run at a speed corresponding to the wind speed, but since there is no control to control the maximum speed between stations, there is no way for the dispatcher to verbally contact the driver on the train. Because of this, we had to keep up with wind speed conditions and change drivers, making it difficult to maintain thorough communication.

An object of the present invention is to provide an operation control system that enables safe and reliable train running that can quickly follow weather conditions.

[Means for solving problems]

The above purpose is to automatically detect weather conditions on the ground operation management system side, transmit acceleration/deceleration command information and maximum speed limit information between stations that match the weather conditions to the onboard side, and This is achieved by controlling the speed by taking into account information from the

[Effect]

The ground-side operation management system of the present invention installs anemometers and rain gauges along the railway line where operation management is performed, automatically records the status of these instruments at all times, and transmits the results to onboard trains. It works like that. Therefore, the automatic train operation device on the top of the train automatically limits the acceleration/deceleration and maximum speed between stations when the train is running, so it can quickly follow changes in weather conditions and without human intervention. Trains can run safely and reliably.
