Description

  The present invention relates to a door opening / closing control system that opens and closes a door for a passenger of a vehicle.

  Conventionally, an automatic door equipped in a building or the like automatically opens a door by detecting that a person is approaching with a light sensor or a sound wave sensor, and automatically closes the door when a person moves away and cannot be detected. It has been broken.

  In addition, automatic doors such as trains and buses, when getting on and off, are confirmed by the conductor or driver to visually confirm or look at the images of multiple TV cameras, confirm that there are no people at each gate and close the door ( The door is closed manually after the buzzer sounds.

Further, in the boarding confirmation system (Patent Document 1), it is performed to allow passengers to carry an IC tag and read the identification information to confirm whether all the passengers are on board.
JP 2003-30707 A

  In the former technique described above, when a person gets on and off a moving vehicle such as a train or a bus, even if a disabled person is moving to get on and off the door of the vehicle, it must be near the door. There was a problem that the door was closed and could not be used.

  In addition, in the second technique described above, whether a person (conductor, conductor) is approaching the door opening / closing part visually (mirror, TV camera), or a disabled person gets on the seat, etc. It was necessary to close the door manually after confirming this, and there was a problem that these situations could not be automatically detected and displayed.

  Further, in the third technique described above, it is only possible to detect the person who got on the vehicle by reading the IC tag attached to the passenger who got on the vehicle. There is a problem that it is impossible to detect and display a situation such as getting close to the entrance / exit and getting on.

  In order to solve these problems, the present invention allows passengers to carry IC tags, reads the IC tags with a plurality of IC tag readers arranged near the entrance of the vehicle, identifies the position, and moves the position. The purpose is to create a state transition and display the boarding / exiting state.

  Therefore, it is possible to specify the position of the passenger having the IC tag and display the state, and to open and close the door more safely and reliably.

  According to the present invention, the position of a passenger who has an IC tag is specified and displayed, and the door can be opened and closed more safely and reliably.

  The present invention allows an passenger to carry an IC tag, reads the IC tag with a plurality of IC tag readers arranged in the vicinity of the entrance of the vehicle, identifies its position, creates a state transition based on the movement of the position, and gets on and off Realized status display.

FIG. 1 shows a system configuration diagram of the present invention.
In FIG. 1, an IC tag card 1 is a card (for example, a train or bus commuter pass) to which an IC tag is attached, and is carried by a person getting on and off the vehicle.

  The IC tag 2 is an IC tag that can read and write information wirelessly. Here, the information shown in FIG. 4 (tag ID, physical handy type information, physical handy severity information, boarding information) / Bus stop section, boarding / exiting period, etc.))).

  A plurality of IC tag readers 3 are arranged in the vicinity of the entrance of the vehicle. The IC tag reader 3 transmits the IC tag 2 by changing the radio wave intensity, and determines the radio wave intensity when information can be read from the IC tag 2 or when the information cannot be read. Originally, the distance (the distance between the IC tag reader and the IC tag) is calculated by referring to a table registered by measuring the relationship between the radio wave intensity and the distance in advance, or the information is read from the IC tag. is there.

  The processing device 4 controls the plurality of IC tag readers 3 to calculate the distance to the IC tag 2, and the position (coordinate (X, Y, Z) or the position on the layout (map) of the IC tag 2 from these calculated distances. Latitude, longitude, altitude), etc. Here, IC tag position specifying means 5, IC tag position movement trajectory storage means 6, boarding / departure determination means 7, emergency call sending means 8, door opening / closing It comprises a control signal sending means 9, a timer 10, an IC tag position information table 11, a layout information DB 12, an IC tag state table 13, and the like.

  The IC tag position specifying means 5 specifies the position of the IC tag 2, and the IC tag 2 in the IC tag card 1 possessed by the passenger from a plurality of IC tag readers 3 arranged in the vicinity of the entrance / exit of the vehicle. The radio field strength is transmitted with variable, and the relationship between the radio field strength and distance created in advance is registered based on the radio field strength when the information is read from the IC tag 2 or when the information cannot be read. Based on the calculated distances, the position of the IC tag 2 (position (coordinate (X, Y, Z) or latitude / longitude) on the layout (map) is calculated based on the known triangulation principle. (Altitude) is specified (described later with reference to FIGS. 2 to 9).

  The IC tag position movement locus storage means 6 stores the movement locus of the position of the IC tag 2 specified by the IC tag position specification means 5 (described later with reference to FIGS. 2 to 9).

  The boarding / alighting determination means 7 determines boarding / alighting intention based on the movement trajectory of the position of the IC tag 2 affixed to the IC tag card 1 possessed by the passenger (described later with reference to FIGS. 2 to 9). ).

  The emergency call sending means 8 sends an emergency call when the movement locus of the position of the IC tag 2 attached to the IC tag card 1 held by the passenger is determined to be in an emergency state (FIG. 2 to FIG. 2). 9 will be described later).

  The door opening / closing control signal sending means 9 sends a door opening / closing control signal toward a vehicle (not shown) (described later with reference to FIGS. 2 to 9).

The timer 10 measures the current time.
The IC tag position information table 11 is a table for registering the specified position of the IC tag 2 attached to the IC tag card 1 held by the passenger in association with the time (see FIG. 5 and the like).

  The layout information DB 12 is created and registered in advance with a vehicle layout (map).

  The IC tag status table 13 is a table for registering and managing the status and transition of the IC tag 2 attached to the IC tag card 1 possessed by passengers (see FIGS. 8 and 9).

Next, the operation of the configuration of FIG. 1 will be described in detail according to the order of the flowchart of FIG.
FIG. 2 shows a flowchart for explaining the operation of the present invention.

(A) of FIG. 2 shows the storage flowchart of IC tag position specification and a movement locus | trajectory.
In FIG. 2A, S1 reads the IC tag data under the control of a plurality of IC tag readers 3 and specifies the position. This is because the IC tag position specifying means 5 in FIG. 1 instructs a plurality of IC tag readers 3 to transmit the IC tag 2 with a variable radio wave intensity to the IC tag 2 attached to the IC tag card 1 possessed by the passenger. 2, the radio field intensity when the information is read or the radio field intensity when the information cannot be read is measured, the table is created in advance and the correspondence between the radio field intensity and the distance is registered, and a plurality of IC tag readers 3 The distance to the IC tag 2 is calculated, and the position (layout (map (map)) of the IC tag 2 is calculated based on a known triangulation principle based on the calculated distances and the position of the IC tag reader 3 registered in advance. ) Specify the position (coordinates (X, Y, Z) or latitude / longitude / altitude) so that the position of the IC tag 2 affixed to the IC tag card 1 held by the passenger is at the entrance / exit of the vehicle. Near It is possible to identify one on whether the or the vehicle.

  S2 records IC tag data and position information, and deletes non-existing IC tag recording data. This is because the information (IC tag data) read from the IC tag 2 in S1 and the identified position information are recorded in the IC tag position information table 11 described on the right side (see FIG. 5), and absent (cannot be detected). In other words, the IC tag data of the IC tag of the passenger who has got off the vehicle is deleted from the IC tag position information table 11.

  In S3, it is determined whether it is a system stop instruction. If YES, the process ends. In the case of NO, S1 and subsequent steps are repeated.

  As described above, when the information of the IC tag 2 affixed to the IC tag card 1 held by the passenger is read by changing the radio wave intensity from the plurality of IC tag readers 3 arranged in the vicinity of the entrance / exit of the vehicle, the radio wave intensity becomes unreadable. The distance is calculated by referring to the table based on the radio field intensity at the time, and the position of the IC tag 2 is specified by the known triangulation principle based on the calculated distances. The tag position information table 11 can be stored together with the specified time, and the read information can be recorded together. As a result, the position, information, and time of all the IC tags 2 attached to the IC tag card 1 held by the passengers in the vehicle near the entrance / exit of the vehicle are associated with the IC tag position information table 11 every predetermined time. (See FIG. 5).

(B) of FIG. 2 shows the flowchart of determination of boarding / alighting and door opening / closing control.
In FIG. 2B, S11 determines whether it is a station arrival signal. This is a signal that the vehicle may arrive at the station and open and close the door. For example, (1) A door opening signal when the conductor boarding the vehicle presses the door opening / closing switch to the door opening position. ,
(2) In the case of an unmanned driving vehicle, a door opening signal indicating that the door may be opened when the vehicle stops at a predetermined position from the operation system, or (3) near the stop position of the station The IC tag 2 is affixed to the IC tag reader 3 mounted on the vehicle and transmitted by changing the radio wave intensity, and the table is based on the radio wave intensity when the information is read from the IC tag 2 or when the information cannot be read. The door opening signal is transmitted when the distance is calculated with reference to the above, the position of the IC tag is specified based on the calculated distance, and the position falls within the stop position range.

  S12 sends a door opening signal. This sends a door opening signal to the door opening / closing control unit of the vehicle (not shown) based on the door opening signal of S11 to open the door.

  In S13, the IC tag position movement trajectory is analyzed, and the IC tag holder's intention to get on and off is determined. This refers to the position information of the IC tag 2 set for each time in the IC tag position information table 11 and determines the intention to get on and off based on the movement state of the IC tag position (using FIGS. 3 to 9). Will be described later).

  S14 discriminate | determines whether it is an emergency. As a result of the determination in S13, this is determined to be an emergency when the movement state of the position of the IC tag 2 matches the condition that, for example, the floor position of the vehicle does not move even after a predetermined time. In the case of YES, an emergency call is sent in S15, and for example, the emergency call message and the position of the IC tag that has occurred are displayed on the layout of the driver's operation panel. On the other hand, if NO in S14, the process proceeds to S16.

  In S16, it is determined whether the IC tag holder has completed boarding / exiting. As a result of the determination in S13, it is determined whether the boarding has been completed or the boarding has been completed. For example, when getting off in FIG. 7A described later (the state transition (state number) of the IC tag position is 1⇒2⇒4). ⇒6 or 1⇒3⇒2⇒4⇒6) or when boarding (b) in Fig. 7 (IC tag position state transition (state number) is 6⇒2⇒4⇒1 or 6⇒2 ⇒3⇒4⇒1). In the case of YES, since getting off / riding is completed, the process proceeds to S17. In the case of NO, since getting off / boarding is not completed, S13 and subsequent steps are repeated.

S17 discriminate | determines whether it is a station departure signal. This is a signal that the vehicle has arrived at the station and passengers have completed getting on and off, and the door may be closed. For example, (1) The conductor boarding the vehicle sets the door open / close switch to the door closed position. Door close signal when pressed,
(2) In the case of an unmanned driving vehicle, the vehicle stops at a predetermined position from the operation system, and the light sensor arranged at the position where the passenger gets on and off and the door is closed determines that the boarding / exit is completed without detecting a person for a predetermined time or more. This is a door closing signal that can be closed, or (3) a door closing signal issued by a station employee. In the case of YES, a door closing signal is sent in S18, and the process proceeds to S19. In the case of NO, S13 and subsequent steps are repeated.

  In S19, it is determined whether it is a system stop instruction. If YES, the process ends. In the case of NO, S11 and subsequent steps are repeated.

  By referring to the IC tag position information table 11 that stores the position of the IC tag 2 affixed to the IC tag card 1 held by the passengers at predetermined time intervals when the vehicle comes to the stop position. Based on the state transition of the IC tag position, it is possible to determine an emergency situation of passengers, completion of boarding and the like, and to close the door. Details will be sequentially described below.

FIG. 3 shows a flowchart for explaining the operation of the present invention.
In FIG. 3, S21 reads IC tag position information. This reads from the IC tag position information table 11 the position information specified for each predetermined time of the IC tag 2 affixed to the IC tag card 1 possessed by the passenger at S2 in FIG.

In S22, the getting-on / off flag is initially set to OFF and the emergency flag is set to OFF. here,
・ Getting on and off flag
・ ON: There are passengers
・ OFF: No passengers ・ Emergency flag
・ ON: Emergency situation
-OFF: Each represents normal.

In S23, a variable n = 0 is initially determined.
In S24, it is determined whether the number of detected IC tags is 1 or more. If YES, the process proceeds to S25. If NO, the process ends.

In S25, n = n + 1. This adds 1 to the variable n for each iteration.
In S26, the position change (movement trajectory) of the IC tag (n) and physical handy information are analyzed. This analyzes the change in the position of the current IC tag (n) (n is 1, 2, 3,...) And physical handy information (physical disability information) in the read information.

  In S27, it is determined whether or not there is an intention to get on and off. In this analysis of S26, it is determined whether or not there is an intention to get on and off based on the movement information of the position of the current IC tag 2 (for example, it is determined whether or not the state 2 in FIG. 6 described later). If YES, the boarding / alighting flag is set to ON in S28, and the process proceeds to S31. On the other hand, if NO, the process proceeds to S29.

  In S29, it is determined whether there is an urgent intention. In the analysis of S26, it is determined whether there is an emergency intention based on the movement information and physical handy information of the position of the current target IC tag 2 (for example, the position is near the floor of the vehicle and more than a predetermined time) , Determine if there is an urgent intention to move). If YES, the emergency flag is set to ON in S30, and the process proceeds to S31. If NO, the process proceeds to S31.

  S31 determines whether n = number of detected IC tags. In the case of YES, since the processing from S25 to S30 is repeated for all detected IC tags, the processing ends. If NO, n = n + 1 in S25, and S26 to S30 are repeated for the next IC tag 2.

  As described above, the position of the IC tag 2 attached to the IC tag card 1 possessed by the passenger is specified and recorded in the IC tag position information table 11 every predetermined time, and the IC tag position information table 11 is referred to and the IC tag position information table 11 is referred to. There is a willingness to get on and off based on the moving state of the tag 2 position, analyze the emergency situation, the getting on / off flag is ON (the passenger is getting on / off), the emergency flag is ON (the passenger has fallen on the floor) It is possible to set the status).

  FIG. 4 shows an example of the data structure of the IC tag of the present invention. This is an example of a data structure that is written in advance in the IC tag 2 attached to the IC tag card 1 possessed by the passenger, and here, the following data shown in the figure is written.

・ Tag ID:
・ Physical handy type information:
・ Physical handy severity information:
・ Boarding information:
・ Other:
Here, the tag ID is an ID for uniquely identifying the IC tag 2 and for uniquely transmitting and calling a wireless radio signal to read information. Physical handy type information and physical handicap severity information include physical handy type information (type information such as hearing impairment) and physical information of passengers who have IC tag card 1 (for example, commuter pass) with IC tag 2 attached. Handy severity information (severity in that type (severity such as light, medium, heavy, etc.)). The boarding / alighting information is boarding / alighting information such as the section of the station (stop) where the passengers can get on and off, and the validity period.

FIG. 5 is a diagram for explaining the location of the present invention.
FIG. 5A shows an example of the data structure of the IC tag position information table. The IC tag position information table 11 is based on the radio wave intensity when reading from the IC tag 2 by changing the radio wave intensity from a plurality of IC tag readers 3 installed in the vicinity of the entrance / exit of the vehicle or the radio wave intensity when reading becomes impossible. The distance is calculated by referring to a previously created table (not shown), and the position of the IC tag 2 obtained by the known triangulation principle based on these distances and the information read from the IC tag 2 are set. Here, the following information shown in the figure is registered in association with each other.

·Times of Day:
・ Tag ID:
・ Physical handy type:
・ Physical handicap severity:
・ Vehicle number:
·location information:
・ Other:
Here, the time is the time when the position of the IC tag 2 attached to the IC tag card 1 possessed by the passenger is specified. The tag ID, physical handy type, and physical handy severity are the tag ID, physical handy type, and physical handy severity read from the IC tag 2. The vehicle number is a vehicle number that specifies the position of the IC tag 2. The position information is the position information specified by the IC tag 2. Others are registered other information read from the IC tag 2 (for example, the above-described boarding / alighting information).

  FIG. 5B shows a layout example. The layout shown in the drawing is a layout that has been created and registered in advance in the layout information DB 12 and is displayed on a display device. Here, the layout of a vehicle (in a train) and its entrance / exit (doors 1, 2, 3) is displayed, and an example is shown in which the movement locus (movement transition) of the position of a specific IC tag 2 affixed to the IC tag card 1 possessed by a certain passenger is obtained and displayed as shown in the bold line in the figure. . These movement trajectories (movement transitions) are represented by bold lines as time passes based on the position of the same IC tag 2 in the IC tag position information table 11 in FIG. It is possible to present the situation in an easy-to-understand manner. Here, since a large number of passengers usually get on and off, if the movement trajectory of the position of each IC tag 2 is displayed, it will become invisible, so that it will be shown in the state display screen example of FIG. 9 described later. Thus, the state is displayed in a color corresponding to the state 1, 2, 3, 4, 5, 6 (see FIGS. 6 to 9). Details will be sequentially described below.

FIG. 6 shows an example of logic for determining the intention to get on and off of the present invention. Here, as the item information in the upper row,

・ Moving direction of IC tag:
・ Physical handy information:
・ Estimated situation:
・ Determination of intention to get on and off at the latest time:
-State number (state transition number):
・ Other:
It was set. Here, “IC tag position change after door open” is a change in the position of the IC tag after the vehicle door is opened (opened), and the IC tag position information of FIG. Focusing on the change in the position of the same IC tag based on the time recorded in the table 11, they are classified as shown in the lower part of the figure. “Moving direction of IC tag” is classified as shown in the lower row based on the fact that the IC tag moves in the direction of the door and the direction cannot be specified. “Physical handy information” is the physical handy information read from the IC tag 2 set in the equivalence column as shown in the lower row. The “estimated situation” is a classification of the estimated situation as shown in the lower part based on the position and moving direction of the IC tag 2. “Determination of boarding / alighting intention at the latest time” shows the classification in which the boarding / alighting intention at the latest time is determined based on the classification of the item information as shown in the lower row. The “state number (state transition number)” is a number assigned to the intention to get on and off (see (c) of FIG. 7).

  As described above, each category for the upper item information is set to determine the intention to get on and off at the latest time, and the state number (1, 2, 3, 4, 5, 6) is uniquely assigned to the intention to get on and off. Thus, the specified position of the IC tag 2 affixed to the IC tag card 1 possessed by the passenger is recorded in the IC tag position information table 11 in association with the time, and the time in the IC tag position information table 11 is recorded. It is possible to track the movement transition of the position of the IC tag 2, determine the intention to get on and off, and display the movement state (movement transition) sequentially with the state number (any one of 1 to 6) (FIG. 7 to FIG. 9 will be described later).

  FIG. 7 shows an example of state transition of the IC tag holder of the present invention. As described above, when the holder (passenger) who has the IC tag card 1 with the IC tag 2 attached gets on and off the vehicle, the position of the IC tag 2 is specified at predetermined time intervals. It is recorded in the tag position information table 11, the movement of the position for each IC tag is tracked based on the time in the IC tag position information table 11, its intention to get on and off is determined in FIG. The example of the movement transition of a number (intention to get on and off) is shown.
