Embodiment Construction

[0040] The main feature of the present invention is to predict the variation of the wheel diameter based on experimental values ​​or empirical values, and to use the largest available wheel diameter as the steady state of the wheel diameter. Therefore, the variation of the wheel diameter is always in one direction, and the actual position is ahead of the position grasped by the vehicle system, so there is no need to add a safety margin distance. In addition, in this case, since the position correction by the ground device is a process for preventing the stop position from stopping closer to the target, it is unnecessary to be on the safe side even if it cannot be obtained by accident. Multiple conversions can reduce the number of settings for ground devices.

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings. figure 1 An example of the configuration of the overall system for realizing the train control method of the pre...

Abstract

The present invention provides a train control method which has the advantages of no requirement of adding the safe clearance distance, capability of reducing the number of ground devices and excellent seating effect. The train controller which controls the train through transmitting information to a ground train control part comprises an in-train control part which is provided with an in-train storing part that pre-stores the likely-changing maximum wheel diameter and the least wheel diameter of the wheel diameter and a speed protection mode. The current position information and speed information of the vehicle are generated based on the maximum wheel diameter, the detected rotating number of wheel and the position information of vehicle received from the ground devices. A corresponding speed protection mode is extracted from the in-train storing part based on the current position information and the stop position target information received from the ground train control part. The brake output is outputted based on the extracted speed protection mode and the generated current position information and speed information.

Description

technical field [0001] The present invention relates to a train control device for trains moving on rails, such as railways, monorails, LRT (Light Rail Transit: Light Rail Transit), AGT (Automated Guideway Transit: Guidance Rail Transit) and other urban transportation. Background technique [0002] The ground system provides the limit that the vehicle system can travel (hereinafter referred to as the stop position target information), and has a speed protection mode that does not travel beyond the limit, and controls the speed by comparing its own position with the speed protection mode so as not to exceed the limit etc. Safety protection is realized by performing speed control corresponding to the own position. In such a train control method, in order to calculate the own position, the method of obtaining the own position by integrating the number of revolutions of the wheels is often used. In the past, the self-position was calculated using the initial value or the wheel d...
