  If the train departure determination is performed using the state change of the track circuit, the departure time of the train cannot be determined until the train departs and enters the next track circuit. Even if it departs, it is indistinguishable from the delayed state. For this reason, there is a problem that it is difficult to provide accurate arrival guidance when train arrival guidance is performed based on the departure information of the near station. An object of the present invention is to provide more accurate arrival guidance.

  In order to solve the above-mentioned problem, one of the representative train arrival / departure time estimation devices according to the present invention is information on the time taken from when the platform door is normally closed to when the train stopped at the platform starts. When a certain departure correction time is held and platform door closing information is received indicating that the platform door has been closed normally, the departure correction time is added to the time when the platform door closing information is received to This is accomplished by calculating an estimate.

  In order to solve the above-mentioned problem, one of the representative train arrival / departure time estimation devices according to the present invention obtains the stop time, which is information on the time the train stays at the home, from the operation management device, Holds the arrival correction time, which is the time it takes for the home door to open normally after it arrives at the home, and receives the home door opening information indicating that the home door has opened normally. This is achieved by calculating the estimated value of the departure time of the train by adding the stop time and arrival correction time to the time when the door opening information is received.

  Since the departure time of the train is estimated and calculated at the time of the platform door closing determination time, the departure time can be obtained prior to the actual departure of the train. As a result, it is possible to determine the departure time before the departure of the train regardless of the presence or absence of a delay, and thus accurate arrival guidance is possible.

  As modes for carrying out the present invention, examples will be described below with reference to the drawings.

  In the first embodiment, the train arrival time estimation device receives the platform door closing information from the platform door control device, estimates and calculates the departure time of the train, holds the estimated diagram data, and is an information display device installed at another station. Next, a method for displaying the estimated departure time of the train held in the estimated diagram data will be described.

  FIG. 1 shows the apparatus configuration. When the train 5 travels on the track 6 and arrives at the station 7 </ b> A, the platform door control device 2 performs opening / closing control of the platform door 8. The train arrival / departure time estimation apparatus 1 includes a calculation unit 201, an information interface unit 202, and a calculation data holding unit 203.

  In the train arrival time estimation device 1, the information interface unit 202 receives a state in which the home door control device 2 closes the home door 8, and the calculation unit 201 calculates the departure time of the station 7 </ b> A of the train 5 and stores it in the calculation data holding unit 203. Hold. The train departure time estimation device 1 displays the calculated departure time of the station 7A of the train 5 on the information display device 4 installed at the station 7B in the traveling direction of the train 5 via the information transmission device 3.

  The calculation unit 201 temporarily executes program execution and control-in-progress information. For example, known components such as a CPU and a memory of a personal computer can be used.

  The information interface unit 202 transmits and receives information between the devices. For example, Ethernet (registered trademark) connectors, USB ports, optical fiber networks, wireless LANs, wireless networks such as mobile phones, and well-known components such as wireless communication using frequency modulation between ground units and trains, and Means are available.

  The calculation data holding unit 203 stores programs and data. For example, known components such as a hard disk drive (HDD), a solid state drive (SSD), and a flash memory can be used.

  The information display device 4 has a function of receiving and displaying the departure time of the station 7A of the train 5 from the train departure time estimation device 1. As a function to display, well-known components, such as a liquid crystal display, a dot matrix LED, and a CRT display, can be used, for example.

  FIG. 2 is a diagram showing the relationship of the processing configuration in the train departure time estimation device shown in FIG.

  The function of the train arrival / departure time estimation device 1 will be described. The input / output interface function 104 inputs the status information of the platform door control device 2 and sends it to the train departure time calculation function 102, and the station 7 A departure time of the train 5 included in the estimated diagram data 103 from the estimated diagram output function 105. The information is received and output to the information transmission device 3.

  The train departure time calculation function 102 uses the status information of the platform door control device 2 received from the input / output interface function 104 and the time information from the platform door closing to the train departure held in the platform door closing / departure time element data 101. Thus, the estimated departure time at which the train 5 departs from the station 7 </ b> A is created and held in the estimated diagram data 103.

  The estimated diagram output function 105 sends the estimated departure time when the train 5 held in the estimated diagram data 103 leaves the station 7A to the input / output interface function 104 in order to display it on the information display device 4 of the station 7B.

  As shown in FIG. 1, the input / output interface function 104 is in the information interface unit 202, the train departure time calculation function 102 and the estimated diagram output function 105 are in the calculation unit 201, the platform door closed departure time data 101 and the estimated diagram. The data 103 corresponds to the calculation data holding unit 203, respectively.

  Processing performed by the train departure time calculation function 102 will be described with reference to FIG. This process is performed, for example, by a process executed at regular intervals.

  In process 1001, the train departure time calculation function 102 starts this process. Thereafter, the process proceeds to process 1002.

  In process 1002, the train departure time calculation function 102 confirms the presence or absence of platform door closing information on the platform door 8 from the platform door control device 2 as an input to the input / output interface function 104. Thereafter, the process proceeds to process 1003.

  In processing 1003, the train departure time calculation function 102 transitions to processing 1006 when there is no platform door closing information. When there is home door closing information, the process proceeds to processing 1004.

  In processing 1004, the train departure time calculation function 102 receives the time value from the platform door closing departure time raw data 101 to the train departure time from the platform door closing departure raw data 101, and adds the platform door closing time and the time value to the train 5 Calculate the estimated departure time. Thereafter, the process proceeds to process 1005.

  In processing 1005, the train departure time calculation function 102 stores the estimated departure time in the estimated diagram data 103. Thereafter, the process proceeds to process 1006.

  In process 1006, the train departure time calculation function 102 ends this process.

  Among these, as a method for confirming the presence or absence of the home door closing information of the platform door 8 from the platform door control device 2 performed in the process 1002, for example, the door state where the platform door control device 2 of the station 7 is installed in a platform or the like not shown. There is a method of receiving information that outputs a lighting extinction lamp according to the open / close state of the platform door.

  The contents of the raw data 101 when the home door is closed will be described with reference to FIG. The time value from the closing of the home door to the departure holds a value corresponding to each condition for each station, each line, each driving direction, each train type, each day of the week, and each time zone. For example, each station stop on the first line of the station 7A uses 10 seconds as a time value from when the platform door closes on a weekday night until the train departs.

  As the time zone setting, for example, a time value such as 13:00 to 16:00 may be specified. These values may not use conditions for each time zone. For example, 15 seconds is used for the fast speed on the first line of the station 7A without dividing the conditions by day of the week and time zone. The same applies to the conditions for each other station, each line, each driving direction, and each train type. For example, a common value may be used for all stations, all lines, all directions in all directions, all vehicle types, all days of the week, and all time zones. In this case, one time value may be stored as the platform door closing departure raw data 101.

  The time value stored in the platform door closing departure time data 101 shown in FIG. 4 is obtained by, for example, summing up the actual value difference between the platform door closing time and the departure time at the time of business operation, and the average value, median value, etc. You can decide by performing statistical processing. Alternatively, the value may be a minimum value or a maximum value, or may be a value determined by a railway operator (not shown) instead of an actual value.

  In process 2002, estimated diagram output function 105 receives the estimated departure time of the train from estimated diagram data 103. Thereafter, the process proceeds to process 2003.

  In process 2003, the estimated diagram output function 105 sends the estimated departure time of the train to the input / output interface function 104 in order to display it on the station information display device. Then, the process proceeds to process 2004.

  In process 2004, the estimated diagram output function 105 checks whether the estimated departure times of all trains have been sent. If there is an estimated departure time for a train that has not yet been sent, the processing transitions to processing 2002. If the estimated departure times of all trains have been sent, the process proceeds to process 2005.

  In processing 2005, the estimation diagram output function 105 ends this processing.

  With the above processing, the train arrival time estimation device 1 estimates and calculates the time when the train 5 leaves the station 7A when the platform door closing information is input from the platform door control device 2 to the train arrival time estimation device 1. it can. If the time value from when the platform door 8 is closed when the train 5 departs from the station 7A until the train 5 departs is 15 seconds, the platform door closed departure time data 101 has a time value of 15 seconds. When the home door 8 is closed, the train arrival time estimation device 1 can estimate that the train 5 leaves the station 7A after 15 seconds. Thereby, the train arrival time estimation device 1 can display the departure time at a stage before the train 5 leaves the station 7A at the station 7B.

  The train arrival / departure time estimation device 1 described here receives, for example, a diagram data held by a well-known operation management device (not shown), performs the process of the train departure time calculation function 102, and operates the estimated diagram data 103 thus created. You may return to a management apparatus. The processing performed by the train arrival / departure time estimation device 1 may be performed in a known operation management device that is not shown.

The data 103 corresponds to the calculation data holding unit 203, the input / output interface function 108 corresponds to the information interface unit 602, and the stop time creation function 106 corresponds to the calculation unit 601 and the calculation data holding unit 603.

  Processing performed by the train departure time calculation function 102 will be described with reference to FIG. This process is performed, for example, by a process executed at regular intervals.

  In process 3001, the train departure time calculation function 102 starts this process. Thereafter, the process proceeds to process 3002.

  In process 3002, the train departure time calculation function 102 confirms the presence or absence of platform door opening information of the platform door 8 from the platform door control device 2 as an input to the input / output interface function 104. Thereafter, the process proceeds to process 3003.

  In process 3003, the train departure time calculation function 102 transitions to process 3007 when there is no platform door opening information. If there is home door opening information, the process proceeds to processing 3004.

  In process 3004, the train departure time calculation function 102 receives stop time information from the operation management device 9. Thereafter, the process proceeds to process 3005.
