Description

  The present invention relates to a train control device that controls a train driving / braking device to adjust a train speed according to a speed limit.

  As a train control device that controls the train driving / braking device and adjusts the train speed according to the speed limit, there is a multi-stage brake control ATC (Automatic Train Control). In the multi-stage brake control ATC, the speed limit information obtained from the ATC ground device via the rail is compared with the train speed obtained from the pulse information of the speed generator, and control is performed so that the train speed does not exceed the speed limit. . For example, when the train speed exceeds the speed limit, a regular maximum brake command is output to the train drive / braking device, and the train speed is controlled to be lower than the speed limit.

  There is also an ATO (Automatic Train Operation) device that operates under such a multistage brake control ATC. The ATO device calculates the power running / brake command by comparing the target speed pattern set within the range not exceeding the speed limit of the ATC and the train speed, and gives the train driving / braking device to adjust the train speed. And trains are operated automatically. The ATO device has permanent speed limit information set according to the gradient and curve of the route, and creates a target pattern according to the permanent speed limit.

  Even if the train follows the target travel pattern obtained in advance and the target travel pattern and the actual travel pattern deviate, the actual travel pattern becomes the target travel pattern without deteriorating the ride comfort and reducing the stop accuracy. Some have been made to approach (for example, see Patent Document 1).

In addition, the target speed is calculated so that the difference between the target arrival time at the predicted target position of the train and the predicted arrival time at the predicted target position is small and the displacement of the target speed is small. Some have been made compatible (for example, see Patent Document 2).

  However, when train operation becomes dense, such as during morning and evening rush hours, the distance between trains becomes shorter, and when the preceding train is delayed, the following train approaches the preceding train further, and a brake command is sent to the train drive / braking device. More output. In the ATC system, there is a range where the following train cannot enter immediately after the preceding train in order to prevent collision between trains, and the speed limit decreases as the train approaches the range, while the speed limit increases as the distance increases. Is a signal condition that gradually increases.

  That is, in the section close to the preceding train, the speed limit is lower than the permanent speed limit. If the speed is too close to the preceding train, the ATC brake is applied in conflict with the lower speed limit. In the conventional multi-stage brake control ATC, the train can know the speed limit of the existing line position by means of the ATC signal, but it is not known whether the speed limit of the preceding closed section is lowered due to the delay of the preceding train.

  In addition, if the signal at the on-line position is not a stop signal (zero speed limit), the departure can be made, but if the preceding train is stopped, the stop signal is applied in the next blockage section and the ATC brake is applied. When the preceding train enters the next section, the starting speed is increased because the speed limit of the standing line position increases again. However, when the next train enters the next blockage section, it becomes a stop signal and the ATC brake is applied. When the preceding train is delayed while the trains are traveling densely in this way, the subsequent train repeats acceleration and deceleration in a short time, and the ride comfort becomes worse.

  The present invention has been made in order to solve such problems, and provides a train control device that can suppress the repetition of acceleration and deceleration due to the delay of the preceding train and improve the riding comfort of the train. .

  The train control device of the present invention determines a point where the riding comfort is bad based on the acceleration / deceleration information and position information of the train, and the acceleration / deceleration information of the train where the riding feeling is bad is obtained by using the diamond information, time information, and position information. Riding comfort information recording means for recording in association with, riding comfort improvement learning means for correcting the speed limit of the point so as to reduce the acceleration and deceleration of the point where the riding comfort determined by the riding comfort information recording means, Based on the riding comfort improvement control information recording means for recording the correction result of the speed limit by the riding comfort improvement learning means in association with the diamond information, time information, and position information, and the diamond information, time information, and position information at the current time point, Refer to the speed limit correction result recorded in the riding comfort improvement control information recording means, and determine the power running or brake command according to the speed limit correction result and the train speed Characterized by comprising an automatic train operation system that.

  ADVANTAGE OF THE INVENTION According to this invention, the repetition of the acceleration and deceleration by the delay of a preceding train can be suppressed, and the riding comfort of a train can be improved.

  FIG. 1 is a configuration diagram of a train control apparatus according to a first embodiment of this invention.

The vehicle 11 travels with the wheels 12 guided by the rails 13, detects station stop information and absolute position information from the ground element 14 arranged along the rails 13 by the position detection means 15, and inputs them to the train control device 16. To do. The train control device 16 receives the train speed v from the speed detection means 17 that detects the speed of the train according to the rotation state of the axle of the wheel 12, and receives the acceleration α from the acceleration detection means 18 that detects the acceleration / deceleration of the vehicle. The speed limit v ′ obtained from the ATC ground device via the rail is input. The train control device 16 calculates a power running / brake command based on the input information and outputs it to the drive / brake device 19 that drives / brakes the train.

  The automatic train control device 20 of the train control device 16 compares the speed limit information obtained from the ATC ground device via the rail with the train speed, and controls so that the train speed does not exceed the speed limit. Moreover, the automatic train driving device 21 of the train control device 16 obtains its own train position based on the position information from the position detection means 15 and the speed information from the speed detection means 17, and based on the own train position, the route information database ( A target speed pattern is created with reference to a slope, a curve, permanent speed limit information, etc. (not shown). This target speed pattern is expressed, for example, as a target speed for the own train position, and a power running / brake command is calculated according to the relationship between the speed information obtained from the speed detecting means 17 and the target speed, and the driving / braking device 19 is Is output.

  The riding comfort information recording means 22 of the train control device 16 determines a point where the riding comfort is poor based on the acceleration / deceleration information and position information of the train. It is recorded in association with time information and position information. Further, the riding comfort improvement learning means 23 of the train control device 16 corrects the speed limit at the point so as to reduce the acceleration / deceleration at the point where the riding comfort is poor. Furthermore, the riding comfort improvement control information recording means 24 of the train control device 16 records the correction result of the speed limit by the riding comfort improvement learning means 23 in association with the diamond information, time information, and position information.

  The riding comfort information recording unit 22 detects a point of poor riding comfort based on the acceleration / deceleration α acquired from the acceleration detecting unit 18 or the acceleration / deceleration obtained from the time change rate of the train speed v acquired from the speed detecting unit 17. When a point with poor riding comfort is detected, the acceleration / deceleration and power running / brake command at that time are recorded in association with diamond information, time information, position information, and the like. For example, the ride quality only gets worse during morning and evening rush hours, because the speed limit temporarily decreases with respect to the permanent speed limit due to the delay of the preceding train, so that the train speed exceeds the limit speed and the ATC There is a possibility that the brakes are applied and a large deceleration occurs, resulting in poor ride comfort.

  Next, the riding comfort improvement learning means 23 is used to treat temporary speed limitations that are thought to have occurred due to poor riding comfort as virtual permanent speed limitation information in association with diagram information and train position information. The speed for passing through the point without acceleration / deceleration is obtained, and the value is set as the speed limit.

  The riding comfort improvement control information recording means 24 records the speed limit corrected by the riding comfort improvement learning means 23, and the automatic train driving device 21 of the train control device 16 is the timetable information, time information, and position information at that time. Based on the above, the correction speed limit information recorded in the riding comfort improvement control information recording unit 24 is referred to.

  That is, the automatic train driving device 21 provides a ride comfort in addition to the gradient, curve, permanent speed limit information, etc. obtained by referring to a route information database (not shown) based on the position of the own train when the target speed pattern is created. By using the corrected speed limit information recorded in the improvement control information recording unit 24, it is possible to prevent the ride comfort from being deteriorated due to an unexpected ATC brake operation.

  On the other hand, a driving assistance device is provided, and the automatic train driving device 21 creates a target speed pattern without referring to the corrected speed restriction information recorded in the riding comfort improvement control information recording means 24 at the time of creating the target speed pattern. The corrected speed limit information recorded in the riding comfort improvement control information recording means 24 by the device may be displayed on a monitor (not shown) of the cab. As a result, the driver can be informed that the speed limit of the other side is temporarily lowered, and the speed can be lowered by a gentle manual brake operation in advance, so that the riding comfort can be prevented from deteriorating.

  According to the embodiment of the present invention, the point where the riding comfort is bad is determined based on the acceleration / deceleration information and the position information of the train, and the acceleration / deceleration information of the train where the riding comfort is bad is obtained as the diamond information, the time information, Riding comfort information recording means 22 for recording in association with the position information, and riding comfort improvement learning means for correcting the speed limit of the point so as to reduce the acceleration / deceleration at the point with poor riding comfort determined by the riding comfort information recording means 22 23 and a riding comfort improvement control information recording means 24 for recording the correction result of the speed limit by the riding comfort improvement learning means 23 in association with the diamond information, time information, and position information. Refer to the recorded speed limit correction result and determine the powering or brake command according to the speed limit correction result and the train speed. You can stop.

  In other words, train trains / trains that generate deceleration-acceleration that degrades the riding comfort of trains are learned, and the speed of passing through the relevant point is calculated automatically without deceleration-acceleration. The ride comfort is improved. In addition, since the vehicle travels at a constant low speed instead of repeatedly decelerating and accelerating, it is possible to shorten the time required to pass the point, and in that case, the amount of power required for train operation can be reduced. .
