Description

  The present invention relates to an improvement in the reliability of an open / close door control system for a railway vehicle.

As seen in Patent Document 1 below, there is proposed a railway vehicle opening / closing door control system that selects a door to be unlocked in accordance with the platform length when the length of the train vehicle is longer than the platform length of the stop station. .
This open / close door control system for railcars aims to reduce the burden on passengers and reduce the burden on the train, and to further improve the safety of train operation. The present invention provides a train management device that executes operation management items such as in-car broadcast, guidance to a driver, and train control. One function of train control is to perform door closing control that cannot be opened due to the relationship between the station platform length and the train length.

  Here, the position detection of the train is performed when the train starts moving, at the same time, the accumulation of the travel distance is started by the signal of the tacho generator which is information in the vehicle, and when the distance data is given, When a train arrives at a specific station based on information stored in advance, door closing control when there is a door that cannot be opened is performed corresponding to the platform of the station.

  On the other hand, as a method for improving the accuracy of position detection of a railway vehicle by a tacho generator, as in Patent Documents 2 and 3, position detection using GPS (Global Positioning System) that is information outside the vehicle, There has also been proposed a method in which position detection based on a tacho-generator signal, which is information of the above, is combined.

JP 63-249406 A JP 2007-135291 A Japanese Patent Laid-Open No. 2004-231100

  In the open / close door control system for a railway vehicle of Patent Document 1 described above, a method using a tacho generator signal, which is information in the vehicle, is used as a position detection method. The travel distance is calculated using the diameter and the position is detected from the travel distance data in the memory. The wheel rotation speed of the vehicle traveling on the track is an error factor of idling and sliding, and the wheel diameter is initially set. Due to the value + error, the measurement data is also included in the travel distance data. In particular, the error of the wheel rotation speed is affected by the environment of the travel route and is difficult to predict.

In particular, when the distance between stations is long, or when curves and undulations are severe, a large error may occur in the result of position detection using the tachometer.
If the arrival station is misjudged due to the error thus generated and the open / close door selection system malfunctions, the door in the area where there is no platform will open, causing the passenger to accidentally fall out and be injured. The risk of doing so increases. Therefore, it is very important to ensure sufficient reliability for the position detection result used in the open / close door selection system.

  In order to improve the measurement error of position detection using the tachometer, which is information in the vehicle, GPS position detection, which is information from outside the vehicle, as proposed in Patent Documents 2 and 3 above, However, there is a limit to the accuracy of the GPS position detection itself, and there are limits to the accuracy of the detection, and there are also obstacles such as topography, tunnels, buildings, and trees. May not be able to receive radio waves correctly, and accurate position detection may not always be possible.

  Therefore, when applying to a railway vehicle door control system, if the position detection results of both do not match, the driver and crew will carefully select which door is appropriate and select the door. After all, it was necessary to give a great mental burden to the driver and the crew to ensure safety.

  Therefore, in the present invention, in order to solve the above-described problem, a position detection result based on information in the vehicle such as a tachometer is collated with a position detection result based on information outside the vehicle such as GPS, and the result is notified. By providing a means, if both position detection results match, the driver and crew are allowed to open and close the door, and only when a mismatch occurs, the position detection results of the driver and crew are not consistent. When the operator inputs the correct station from the cab display, the actual stop station and the station recognized by the open / close door selection system are matched to reduce the burden on the crew. While improving the reliability of the position detection results.

  Specifically, the open / close door control system for a railway vehicle of the present invention has a position detection means for detecting the position of the railway vehicle, an information processing device for managing information in the railway vehicle, and a door control device. The information processing device determines an arrival station based on the position of the railway vehicle detected by the position detection means, and opens or closes the door control device among the doors of the railway vehicle according to the platform length of the arrival station. In the open / close door control system for a railway vehicle that commands the door to be operated, the position detecting means detects the position using information from outside the vehicle, and detects the position using information from within the vehicle. The information processing apparatus includes means for comparing position detection results of both position detection apparatuses and notifying the result.

  In the above railcar opening / closing door control system, when the position detection results of the two position detection devices match, the information processing apparatus determines a corresponding arrival station based on the position detection results, and Corresponding to the stop position and the platform head of the arrival station, door opening permission information is transmitted only to the doors to be opened and closed among the railcar doors.

  In the above-described railcar opening / closing door control system, only the door to which the door opening permission information is transmitted receives a door opening operation by a driver or a crew member.

  Furthermore, in the above-described railcar opening / closing door control system, a GPS receiver or a digital ATC vehicle upper member is provided as a device for detecting a position using information from outside the vehicle.

  In the above-described railcar opening / closing door control system, a tacho generator, a brake device, a security device, or a main circuit device is provided as a device that performs position detection using information from within the vehicle.

  Also, in the above-described railcar door opening / closing door control system, the position detection results of the device that detects the position using information from outside the vehicle and the device that detects the position using information from within the vehicle were inconsistent. In the case of having a device that issues a warning to the driver and crew.

  Furthermore, in the above-described railcar opening / closing door control system, when the position detection result is inconsistent, the driver has an apparatus for inputting to the driver's cab or the crew room whether the detection result is correct or not. I made it.

Since the position detection using the tachometer is performed based on information that can be acquired inside the vehicle, it is not affected by the external environment such as a radio wave state because it communicates with an external device. On the other hand, position detection using GPS is not affected by the environment of the vehicle running state such as idling of wheels and sliding because position detection is performed by information acquired from the outside. According to the present invention, the reliability of the position detection result can be improved by combining these two types of detection results having different approaches for position detection.
And since both detection results are collated and the result can be notified to the driver and the crew, it is possible to easily and surely confirm the correctness of the arrival station.

  Position detection methods for open / close door selection systems where reliability of position detection is important include position detection by tachometer generator, which is information inside the vehicle, position detection by GPS, etc., which is information outside the vehicle, and by drivers and crew By combining three types of position detection called artificial position confirmation, the reliability of position detection can be significantly improved.

Embodiments 1 to 5 of the present invention will be described below with reference to the drawings.

[Example 1]
FIG. 1 is a diagram illustrating the operation of the open / close door selection system according to the first embodiment of the present invention.
Since the platform 1 at the station A is a platform that is sufficiently long relative to the length of the vehicle 2, all the doors 3 on the platform side are opened to allow passengers to get on and off.
On the other hand, the platforms 4 and 5 at the stations B and C are shorter than the length of the vehicle 2, so that only the door 3 on the platform side and the platform is opened. However, it is assumed that the driver or other device has stopped the vehicle within the specified error range.

FIG. 2 is a schematic diagram of Embodiment 1 of the present invention.
In the information processing device 8, wheel diameters, station distance information, station GPS position information, and individual door opening / closing information for each stop station are recorded in the database 11 in advance.
When the vehicle 2 departs from the station, the wheel rotation number is sent from the tachometer generator 6 to the information processing device 8, and the information processing device 8 travels the vehicle 2 from the received wheel rotation number and the wheel diameter stored in the database 11. The calculation of the distance is started, and the position detection is performed by comparing the calculated travel distance of the vehicle 2 with the inter-station distance information recorded in the database 11.

  On the other hand, the GPS receiver 7 transmits the received vehicle position data to the information processing device 8, and the information processing device 8 compares the received position data with the GPS position information recorded in the database 11 to detect the position. I do.

  The information processing device 8 compares the position detection result by the tachometer generator 6 detected by the above processing with the position detection result by the GPS receiver 7, and the information processing device 8 detects if the two detection results match. Based on the result, the arrival station is determined, and door opening permission information corresponding to the arrival station recorded in the database 11 is transmitted to the door control device 9.

  Upon receiving the door opening permission information, the door control device 9 sends an opening command to the door to be opened in response to the stop position and the home length at the arrival station by the door opening operation by the driver and crew. The door that has been removed will remain closed.

  On the other hand, in the comparison processing of the position detection results, when the comparison results are inconsistent, the information processing apparatus 8 displays that the inconsistency of the detection results has occurred on the display 10 arranged in the driver's cab or the crew room, A signal (a warning light or a warning sound) is sent to warn the driver and crew.

  The display 10 displays the detection result by the tacho generator 6 and confirms whether the detection result is correct to the driver and the crew. If the detection result displayed on the display device 10 is correct, the driver and the crew member operate the display device 10 to inform the information processing device 8 that the displayed detection result is correct.

  The information processing device 8 that has received the information that the detection result by the tacho generator 6 is correct transmits door opening permission information corresponding to the arrival station to the door control device 9 based on the result of the tacho generator 6 and receives the door. The control device 9 sends an opening command to the door to be opened in response to the stop position and the platform length at the arrival station by the door opening operation by the driver and crew, and for the door that has left the platform Keep closed.

  On the other hand, when the position detection result by the tacho generator 6 and the position detection result by the GPS receiver 7 are inconsistent and the position detection result by the tacho generator 6 displayed on the display 10 is incorrect, the driver and the crew are Correct position information is input from the display 10 and transmitted to the information processing apparatus 8.

  The information processing device 8 that has received this information transmits door opening permission information to the door control device 9 based on the positional information input by the driver and crew, and the door control device 9 that has received this door opening permission information By opening the door by the driver or crew, the stop position at the arrival station, the opening command is sent to the door to be opened according to the platform length, and the crew opens the door to the door that has left the platform. Is disabled and remains closed.

As described above, if the position detection result by the tachometer generator 6 and the position detection result by the GPS receiver 7 do not match, the door opening operation is invalidated until the correct position information is input by the driver and crew. Safety can be further increased.
Furthermore, if such disagreement in position detection results continuously at each station, the latitude and longitude information received by the GPS at that time based on the position information input by the driver and crew Statistical processing is performed on data used for position detection, and the contents of the database 11 used for position detection by the tachometer generator 6 or position detection by the GPS receiver 7 are changed using the processing result. A learning function can also be provided.
It is also possible to perform the learning function using a plurality of vehicles. As shown in FIG. 7, the method is as described above. Data used for position detection when the position detection results are inconsistent is transferred from the wireless communication device 17 mounted on the vehicle to the ground side. The data is transmitted to the installed server 18, statistical processing of the data is performed by the ground-side server 18, and the processing result is transmitted from the ground-side server 18 to the wireless communication device 17, thereby being used for position detection in a plurality of vehicles. The contents of the database 11 to be changed are changed.

FIG. 8 is a flowchart showing the processing procedure of the present invention.
First, position detection based on in-vehicle information using the tacho generator 6 and position detection based on information outside the vehicle using the GPS receiver 7 are executed.

  Next, a comparison is made as to whether the position detection results of the two match, and if the position detection results of the two match, the information processing device 8 transmits door opening permission information to the door control device 9 based on the position detection result. The door control device 9 that has received the door opening permission information determines whether or not the door opening operation is permitted for each of the doors 3 corresponding to the arrival station, based on the received information.

  On the other hand, if the result of the comparison is inconsistent, the information processing device 8 displays a warning on the display 10 and the result of position detection based on the in-vehicle information using the tacho generator 6, as well as to the driver and crew. Notify that the position detection result is inconsistent.

  If it is confirmed that the position detection result displayed by the driver and the crew is correct, the information processing device 8 transmits door opening permission information based on the detection result displayed on the display device 10 to the door control device 9. .

On the other hand, if the position detection result displayed on the driver's cab display 10 is incorrect by the confirmation by the driver or crew, the driver or crew operates the display 10 to correct the position information corresponding to the arrival station. Enter.
Based on the input position information, the information processing device 8 transmits door opening permission information to the door control device 9, and the door control device 9 that receives the information opens the door 3 based on the received information. Set whether or not.

The door opening permission information transmitted from the information processing device 8 to the door control device 9 is as follows for each of the stations A to C in FIG.
When the position detection result is the A station, the platform 1 of the A station has a sufficient length with respect to the vehicle 2. The door opening permission information of the doors 1 to 4 is transmitted.

  When the position detection result is the B station, the stop position with respect to the platform is the same as that of the A station, but the platform 4 of the B station is one car shorter than the length of the vehicle 2, so the NO. The door opening permission information of the doors 1 to 4 is transmitted, and the NO. The opening permission information is not transmitted for the doors 1 to 4.

When the position detection result is C station, the length of platform 5 at station C is the same as that of platform 4 at station B, but the stop position relative to the platform is different. Therefore, when the vehicle 2 stops at the C station, the NO. No. 3-4, NO. No. 1-4, No. 3 NO. The door opening permission information of the doors 1 and 2 is transmitted, and the NO. NO. The door opening permission information is not transmitted to the 3 to 4 doors 3.
The door 3 that has received the door opening permission information enters the door open state when the driver performs the door opening operation. On the other hand, the door 3 that has not received the door opening permission information remains in the door closed state even if the driver performs the door opening operation.
