Hereinafter, an embodiment of a home fence according to the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating an overall configuration of a home fence.
Fig.1 (a) is a top view of the platform 1 in which the platform fence was installed. In the figure, the platform 1 has a plurality of openings 2 in the direction of the length of the platform 1 on the track side rather than the line drawn near the front edge in order to alert the passenger not to enter the track side. Are spaced apart from each other.
FIG. 1B is a configuration diagram of a portion below the platform 1.
Each shield 3 moves up and down through the opening 2. The compressor (CMP) 4 stores air in the air tank 5. The air pipe 6 connected to the air tank 5 controls a lowering electromagnetic valve (D-MV, MV: magnet valve) 7 for controlling the air pressure of the upper air chamber 10 of each pneumatic cylinder and the air pressure of the lower air chamber 11. A lift solenoid valve (U-MV) 8 is attached. When the ascending solenoid valve 8 sends air to the lower air chamber 11, the shield 3 is raised, and when the descending solenoid valve 7 sends air to the upper air chamber 10, the shield 3 is lowered. The control system 12 is connected to a selector (SEL) 14 that controls the ascending solenoid valve 8 and the descending solenoid valve 7 and assigned with individual addresses, and an electric wire 13 as a command line.

FIG. 2 is a diagram showing a detailed configuration of the home fence.
In the figure, a lighting 16 is provided on the side surface of the shield 3 on the track side, and a lamp 17 such as an LCD (Liquid Crystal Display) is provided on the side surface in the lateral direction of the home, on the upper side of the shield 3 or on the side surface on the home side. 18 is provided. Here, the lamps 17 and 18 are lit in different colors. The electric wire 19 supplies electric power to the selector 14 and simultaneously supplies electric power to the lowering electromagnetic valve 7 and the upper electromagnetic valve 8 via the selector 14. Further, the selector 14 controls the power supplied to the illumination 16 and the lamps 17 and 18 so as to be turned on or off.

FIG. 3 is a diagram illustrating a configuration for detecting information specifying a train.
An RFID (Radio Frequency Identification) tag 31 is attached to the lower part of the top car 30 of the train. The RFID tag 31 mainly uses a radio frequency for communication, and includes a memory for recording data, a data processing circuit, and an antenna for carrying data at the radio frequency. The memory stores a train number that is information for specifying a train. A ground element 40 as an RFID tag reader is provided in the ground portion at the entrance of the home, and the train number is read from the RFID tag 31 attached to the head car 30 of the train entering the home and notified to the control system 12. .

FIG. 4 is a diagram illustrating a configuration for detecting a stop position of a train.
A position detection device 41 is provided on the front end line side of the platform 1. The position detection device 41 includes a plurality of light receivers 42 arranged in a matrix. The photoreceptor 42 detects light emitted from the light emitting unit 32 that is a lamp provided at a predetermined reference point of the train. The position detection device 41 detects the stop position of the train from the light receiving body 42 that detects the light emitted from the light emitting unit 32 of the train and the intensity of the light, and notifies the control system 12 of the detected stop position. In the figure, the light detected by the light receiving bodies 42a to 42d is stronger than the light received by the surrounding light receiving bodies 42e to 42j. Accordingly, it is determined that the dotted line indicated by the symbol A is the position of the light emitting unit 32. Here, it is assumed that the reference point is a vehicle body part below the center of the door closest to the head of the head car 30 of the train. The position detection device 41 needs to have a height that can be reliably detected even if the door position of the vehicle changes from when the vehicle is empty to when it is full.

FIG. 5 is a diagram showing the configuration of the conductor switch (door switch) 44.
A light emission switch unit (light emission SW unit) 46 for instructing to turn on or off the light emitting unit 32 of the train is provided in a conductor switch 44 installed in a crew room or the like. The door switch portion 45 of the conductor switch 44 is a switch that controls opening and closing of a train door.

FIG. 6 is a block diagram showing the internal configuration of the control system 12.
The control system 12 includes a database 81, a control content information storage unit 82, a command console 83, a train identification information reception unit 84, a position information reception unit 85, an instruction output unit 86, and an address calculation unit 88.

  The database 81 stores stop train data and master data as door position information. The stop train data is sequential data that associates the train number with the train type and the number of vehicles (both numbers). The master data is data that associates the train type with the door-to-door distance data and the door width data. The inter-door distance data includes data of a reference point, here, a predetermined door position from the center of the door closest to the head of the head car, a distance from each door, and a width of the door. Here, the reference point and the position of the predetermined door are the position of the frontmost door of the front car 30. The control content information storage unit 82 stores the control content information input from the command console 83. The control content information includes, for example, division position information that associates a train number with a vehicle separation position when vehicles with different destinations are combined.

  The train identification information receiving unit 84 receives the train number that the ground unit 40 has read from the RFID tag 31 included in the head car 30 of the train. The position information receiving unit 85 receives information on the address of the selector 14 corresponding to the stop position of the train, here, the center position of the door closest to the head of the head car from the position detection device 41. The address calculation unit 88 obtains the address of each selector 14 whose height of the shield 3 should be changed by calculation processing, and the instruction output unit 86 determines the height of the shield 3 with respect to the selector 14 of the obtained address. Instruct to change. The instruction output unit 86 instructs the selector 14 to turn on or off the illumination 16 and the lamps 17 and 18 of the shield 3.

Next, the operation of the home fence will be described.
When the vehicle is not stopped on the platform 1, all the shields 3 are in the raised state. The interval between the shields 3 is such that passengers cannot pass through in the elevated state, and the height is such that the passengers cannot easily get over in the normal walking state, for example, the height of an adult's waist. Shall. Moreover, the illumination 16 of the shield 3 is turned on. As a result, even if the track side is illuminated and the operation is performed at night or in an underground platform, the train crew can easily monitor the track, so that the incoming train can be operated safely.

  After the preceding train leaves the station, the stop train data, the data such as the train number, type and number of cars that will be arriving next, the master data, the door distance data, the door width data, etc. 12 address calculators 88. Thereby, the address calculation part 88 determines the address of each selector 14 used as each door position in the case of a standard stop position by calculation. Further, when division occurs in the next train, the division position information is similarly sent to the instruction output unit 86 from the control content information storage unit 82 to which data is input in advance by the instruction console 83. When there is division position information, the instruction output unit 86 adds information that can identify the front knitting and the rear knitting, and sends the information to the selector 14 on the electric wire 13.

  Each selector 14 connected to the electric wire 13 acquires and analyzes a command including the corresponding address, and identifies whether or not there is a division, and if there is a division, whether it is a pre-knitting or a post-knitting. Electric power is supplied to the lamp 17 in the case of the front knitting, to the lamp 18 in the case of the rear knitting, and to the lamps 17 and 18 in the case of no division. The selectors 14 at portions other than the standard door position remain off with the lamps 17 and 18. Therefore, since it is possible to simultaneously determine not only the door position but also the presence / absence of the train division and the formation at the time of division, the passenger can be guided according to the destination.

  Next, just before the next train approaches and enters the platform, if it passes over the ground element 40 installed at the ground part of the entrance of the platform, the ground element 40 is installed in the lower part of the top car 30 of the train. The train number is read from the RFID tag 31 and transferred to the control system 12.

  When the train identification information receiving unit 84 receives the train number from the ground unit 40, the control system 12 determines whether or not the train number is currently set on the platform, and only immediately when the train numbers are different. The database 81 is searched using the train number, and the data of the format and the number of both are obtained from the stop train data, and the door distance data and the door width data are obtained from the master data. The address calculation unit 88 calculates the address of the selector 14 that controls the shield 3 related to the door portion for all door positions, using the above-described format, number of both, door distance data, and door width data. And decide. On the other hand, when the train number received by the train identification information receiving unit 84 is the train number currently set for the platform, the address calculation has already been completed, and thus the above processing can be omitted. The above processing is completed before the train stops.

  Immediately before the train stops, when the driver or conductor of the crew room turns on the light emission SW section 46 of the conductor switch 44, the light emitting section 32 provided at the lower part of the center of the door at the top of the leading car 30 Light. On the other hand, when the position detection device 41 provided in the platform 1 receives the light from the light emitting unit 32, the position detection device 41 transfers the position information to the address calculation unit 88 via the position information receiving unit 85 of the control system 12. Next, the address calculation unit 88 compares the sent position information with the address information of the topmost door of the leading car 30 that has already been set, and if there is a difference (offset) in the door center stop position. Gives a new address obtained by increasing / decreasing the offset to all the door addresses, and sends the address on the electric wire 13 through the instruction output unit 86 together with the shield lowering command.

  Each selector 14 connected on the electric wire 13 acquires and analyzes a command including the corresponding address, and performs control to pressurize the descending solenoid valve (D-MV) 7 in accordance with the shield lowering command. The pressure air is sent from the air tank 5 to the lower air chamber 11 through the air pipe 6 and the descending electronic valve (D-MV) 7. As a result, the shield 3 is lowered to the height of the platform 1 or lower and stored. After confirming the above, the driver or conductor in the crew room operates the door SW unit 45 to open the train door.

  Next, when the passenger gets on and off, the conductor operates the door SW unit 45 to close the door of the train, and when the light emitting SW unit 46 is turned off, the lower part of the center of the door at the top of the top car 30 The light emitting unit 32 provided in the light is turned off. As a result, since the position detection device 41 provided in the home cannot receive light, the control system 12 recognizes that the door is closed and shields the selector 14 that has sent the shield lowering command first together with the address. A body raising command is sent out onto the electric wire 13 via the instruction output unit 86.

  Each selector 14 connected on the electric wire 13 acquires and analyzes a command including the corresponding address, and performs control to pressurize the ascending electromagnetic valve (U-MV) 8 according to the shield raising instruction. The pressurized air is sent from the air tank 5 to the upper air chamber 10 through the air pipe 6 and the electronic valve for lifting (U-MV) 8. As a result, the shield 3 rises to a predetermined height on the platform 1 and prevents the passenger from falling.

  Furthermore, the control system 12 that has recognized that the door is closed acquires data of the next train from the stopped train data, and repeats the same processing.

Next, a home fence according to another embodiment will be described.
Here, differences from the above-described embodiment will be mainly described.
In other embodiment, the light emission part 32 is provided in the vehicle body part under all the doors of a train. In addition, the position detection device 41 is installed on the entire surface of the platform 1 on the front end line side. When the train stops and the light emission switch unit 46 is set to ON and the light emission unit 32 is lit, the position detection device 41 notifies the control system 12 of the detection positions of all the light emission units 32 as door position information. The instruction output unit 86 of the control system 12 obtains the address of the selector 14 corresponding to the door position information received by the position information receiving unit 85. Then, it instructs the selector 14 of the obtained address to lower the shield 3 to the position of the platform 1. Thereby, the shield 3 of the part corresponding to the door position of a train can be lowered | hung, without installing the ground element 40 or using the database 81. FIG. For this reason, the introduction cost and maintenance cost of the database system can be reduced.

FIG. 7 is a diagram illustrating another installation example of the light emitting unit 32.
In the figure, a plurality of light emitting sections 32 are attached to a lower part of a door of a vehicle in a closed state, with a predetermined interval, corresponding to the length corresponding to the width of the door. Thereby, it is not necessary to have the database 81 of the control system 12.

In the above description, the pneumatic cylinder is used as the drive unit. However, for example, another actuator such as a hydraulic cylinder or an electric type may be used.
In addition, the instruction output unit 86 can flash the lamps 17 and 18 of the shield 3 by the selector 14 having an address that matches a predetermined condition, and urge the passenger to pay some attention.
Further, the shields 3 are not limited to a single row, and may be installed in two or more rows. The shape of the shields 3 may be an arbitrary shape such as a column shape in addition to a plate shape. For example, by providing the shield 3 with a mechanism that expands in the width direction in the raised state, the number of shields can be reduced to reduce the cost, and the passage of passengers can be effectively prevented. This increases safety. Furthermore, the door position of the next train or the train after the second train can be displayed in advance, which is useful for aligned riding.
Further, if the shield 3 is provided with a pressure sensor, and it is detected that pressure is applied after the light emitting part 32 of the train is turned off, an alarm is output or control is performed so that the train door is not closed. Good. Thereby, it is possible to prevent passengers and luggage from being caught between train doors.
Further, the light emission switch unit 46 and the door switch unit 45 may be interlocked.
Further, the light emitted from the light emitting unit 32 may be blinked periodically as well as simply lighting. This can prevent malfunction when receiving light from another home or outside.

  The control system 12 described above has a computer system inside. The process of operation of the control system 12 described above is stored in a computer-readable recording medium in the form of a program, and the above-described processing is performed by the computer system reading and executing this program. The computer system here includes an OS and hardware such as peripheral devices.

Further, the “computer system” includes a homepage providing environment (or display environment) if a WWW system is used.
The “computer-readable recording medium” refers to a storage device such as a flexible medium, a magneto-optical disk, a portable medium such as a ROM and a CD-ROM, and a hard disk incorporated in a computer system. Furthermore, the “computer-readable recording medium” dynamically holds a program for a short time like a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line. In this case, a volatile memory in a computer system serving as a server or a client in that case is also used to hold a program for a certain period of time. The program may be a program for realizing a part of the functions described above, and may be a program capable of realizing the functions described above in combination with a program already recorded in a computer system.
