Description

[Technical field]

[0001] The present disclosure relates to a platform door system. [Background technology]

[0002] The platform door system has multiple platform doors and a general control device that controls the multiple platform doors. Each platform door has a door pocket that is fixed to the platform of the railway station, a door that is supported in the door pocket so that it can move forward and backward, and an individual control device that is provided in the door pocket and controls the opening and closing of the door. The individual control device is connected to the general control device and controls the opening and closing of the door based on a control signal from the general control device.

[0003] In such platform door systems, one entrance / exit is made up of a pair of doors that move forward and backward from a pair of door pockets installed next to each other. If one of the pair of doors that make up the entrance / exit is called the first door, the other door is called the second door, the door pocket that supports the first door is called the first door pocket, and the door pocket that supports the second door is called the second door pocket, then in conventional platform door systems, an individual control device installed in the first door pocket drives and controls both the first door and the second door.

[0004] In such conventional platform door systems, the second door drive device and various sensors installed in the second door pocket must be connected to an individual control device installed in the first door pocket, so multiple signal wires must be installed between the second door pocket and the first door pocket. Since the first door pocket and the second door pocket are installed on either side of the boarding / alighting entrance, the multiple signal wires must be buried underground under the platform. For this reason, conventional platform door systems had the problem of high installation time and cost.

[0005] Therefore, in recent years, as disclosed in Patent Document 1, for example, a platform door system has been proposed in which individual control devices are provided in the first door pocket and the second door pocket, and the first door is driven by the individual control device provided in the first door pocket and the second door is driven by the individual control device provided in the second door pocket.

[0006] [Patent Document 1] Japanese Patent Application Publication No. 11-43044 Summary of the Invention [Problem to be solved by the invention]

[0007] In the platform doors described in Patent Document 1, each individual control device needs to be configured so that it can send and receive various signals between it and the overall control device. Therefore, in Patent Document 1, a transmission cable is connected to the overall control device, and input and output cables are respectively connected to each individual control device, and the input and output cables are respectively connected to the transmission cable, thereby connecting each individual control device to the overall control device.

[0008] Incidentally, in platform doors installed on station platforms, two doors may be provided in one door pocket. If the configuration of Patent Document 1 is applied to such platform doors, two individual control devices will be provided in one door pocket, and each individual control device will be provided with an input cable and an output cable. As a result, the number of cables connected to the door pocket increases, which creates a problem of increased labor hours during installation work to connect the input cables and output cables to the transmission cable, resulting in increased construction costs.

[0009] The present disclosure has been made to solve the problems described above, and aims to provide a platform door system that can reduce construction labor compared to conventional methods and cut construction time and costs when installing platform doors on platforms. [Means for solving the problem]

[0010] The platform door system according to the present disclosure comprises a first door pocket and a second door pocket arranged adjacent to each other on the platform, a first main door and a first subordinate door supported in the first door pocket so as to be freely movable forward and backward, a second subordinate door supported in the second door pocket so as to be freely movable forward and backward, and a second main door supported in the second door pocket so as to be freely movable forward and backward and arranged adjacent to the first subordinate door, an integrated control device that outputs control signals to control the first main door, the first subordinate door, the second main door, and the second subordinate door, a first main control unit that is arranged in the first door pocket and controls the opening and closing of the first main door based on the control signal, and a first signal line that is arranged in the first door pocket and connected to the first main control unit. and a first slave control unit that controls the opening and closing of the first slave door based on the control signal, a second main control unit that is arranged in the second door pocket and controls the opening and closing of the second main door based on the control signal, a second slave control unit that is arranged in the second door pocket and connected to the second main control unit by a second signal line and controls the opening and closing of the second slave door based on the control signal, a transmission cable at least a portion of which is buried in the platform and connected to the general control device, and connection cables that connect the transmission cable to the first main control unit and the second main control unit, respectively, and the first slave door and the second main door are controlled to open and close in synchronization with each other. The control signal is output in the order of the total control device, the first main control unit, and the second main control unit, and is not output from the total control device to the second main control unit without passing through the first main control unit. Effect of the Invention

[0011] According to the platform door system of the present disclosure, the first main control unit and the first slave control unit can transmit and receive various signals including control signals using the first signal line. Therefore, by simply providing a pair of cables consisting of an input cable and an output cable in the first door pocket, both the first main control unit and the first slave control unit can exchange various signals with the integrated control device. Similarly, the second main control unit and the second slave control unit can transmit and receive various signals including control signals with each other using the second signal line. Therefore, by simply providing a pair of cables consisting of an input cable and an output cable in the second door pocket, both the second main control unit and the second slave control unit can exchange various signals with the integrated control device. In this way, according to the present disclosure, the number of cables connecting each control unit and the transmission cable can be reduced, thereby reducing construction time and costs.

[0013] The embodiments for carrying out the present disclosure will be described with reference to the accompanying drawings. In each drawing, the same or corresponding parts are denoted by the same reference numerals, and the duplicated description will be appropriately simplified or omitted. For the sake of convenience of description, the proportional relationship of the size and shape of the parts shown in each drawing may be exaggerated.

[0014] (Embodiment 1) The first embodiment of the present disclosure will be described in detail with reference to Fig. 1. Fig. 1 shows a schematic diagram of a platform door system 100 according to the first embodiment of the present disclosure.

[0015] The platform door system 100 has a first platform door 10, a second platform door 20, a third platform door 30, and an overall control device 50 that controls each of the platform doors. In this embodiment, a platform door system 100 having three platform doors will be described, however, the number of platform doors that make up the platform door system 100 is not limited to three and can be any number.

[0016] First, the configuration of the platform door will be described using the first platform door 10 as an example. As shown in Fig. 1, the first platform door 10 has a first door pocket 11 fixed to the platform, and a first main door 12A and a first secondary door 12B supported in the first door pocket 11 so as to be movable forward and backward.

[0017] The first door pocket 11 is provided with a first main control unit 13A that controls the opening and closing of the first main door 12A, and a first slave control unit 13B that controls the opening and closing of the first slave door 12B. The first slave control unit 13B is connected to the first main control unit 13A by a first signal line 16 provided inside the first door pocket 11. The first signal line 16 is configured as a signal line in which a plurality of signal lines capable of transmitting signals only in one direction are bundled together, and includes a signal line that transmits various signals output from the first main control unit 13A to the first slave control unit 13B, and a signal line that transmits various signals output from the first slave control unit 13B to the first main control unit 13A.

[0018] A first main driving section 14A and a first main sensor 15A are connected to the first main control section 13A, and a first slave driving section 14B and a first slave sensor 15B are connected to the first slave control section 13B.

[0019] The first main drive unit 14A includes an electric motor and a resolver that detects the rotational position of the electric motor. The electric motor applies a driving force to the first main door 12A based on a control signal output from the first main control unit 13A, causing the first main door 12A to move forward or backward. The resolver outputs detection values ​​of the position and rotational speed of the electric motor to the first main control unit 13A. Details of the control signal will be described later.

[0020] The first main sensor 15A includes a vibration sensor that detects vibrations of the first door pocket 11, a temperature sensor that detects the temperature at any position in the first door pocket 11, and a torque sensor that monitors the torque applied to the electric motor constituting the first main drive unit 14A from the value of the current supplied to the electric motor. Various detection values ​​by the first main sensor 15A are output to the first main control unit 13A.

[0021] As shown in FIG. 1, the first door pocket 11 is provided with a first main control unit 13A, a first main drive unit 14A, and a first main sensor 15A, as well as a first slave control unit 13B, a first slave drive unit 14B, and a first slave sensor 15B. The first slave control unit 13B and the first slave driving unit 14B have the same configuration as the first main control unit 13A and the first main driving unit 14A, respectively. That is, the first slave control unit 13B is connected to the first slave driving unit 14B and the first slave sensor 15B, and the first slave driving unit 14B is configured to include an electric motor and a resolver. The first slave driving unit 14B applies a driving force to the first slave door 12B based on a control signal output from the first slave control unit 13B, causing the first slave door 12B to move forward and backward.

[0022] The first slave sensor 15B includes a torque sensor that monitors the torque applied to the electric motor constituting the first slave drive unit 14B from the current value supplied to the electric motor, and an obstacle sensor that is used to ensure safety around the first door pocket 11. Various detection values ​​by the first slave sensor 15B are output to the first slave control unit 13B. The first slave control unit 13B outputs the various detection values ​​by the first slave sensor 15B to the first main control unit 13A through the first signal line 16.

[0023] The second platform door 20 and the third platform door 30 have a configuration similar to that of the first platform door 10. The second platform door 20 has a second door pocket 21 fixed to the station platform, and a second main door 22A and a second subordinate door 22B supported in the second door pocket 21 so as to be movable forward and backward. The second door pocket 21 is provided with a second main control unit 23A that controls the opening and closing of the second main door 22A, and a second subordinate control unit 23B that controls the opening and closing of the second subordinate door 22B. A second main drive unit 24A and a second main sensor 25A are connected to the second main control unit 23A, and a second subordinate drive unit 24B and a second subordinate sensor 25B are connected to the second subordinate control unit 23B. The second subordinate control unit 23B is connected to the second main control unit 23A by a second signal line 26. The second signal line 26 is configured as a signal line consisting of multiple bundled signal lines that can transmit signals in only one direction, and includes a signal line that transmits various signals output from the second main control unit 23A to the second slave control unit 23B, and a signal line that transmits various signals output from the second slave control unit 23B to the second main control unit 23A.

[0024] The third platform door 30 has a third door pocket 31 fixed to the station platform, and a third door 32A supported so as to be movable forward and backward in the third door pocket 31. The third door pocket 31 is provided with a third control unit 33A that controls the opening and closing of the third door 32A, and a third drive unit 34A and a third sensor 35A are connected to the third control unit 33A.

[0025] A transmission cable 60 is connected to the overall control device 50. As shown in Fig. 1, the transmission cable 60 is provided so as to be located between the overall control device 50 and the first door pocket 11, between the first door pocket 11 and the second door pocket 21, and between the second door pocket 21 and the third door pocket 31, and at least a portion of the transmission cable 60 is buried in the platform. In the present disclosure, the cables buried in these areas and transmitting control signals from the overall control device 50 are collectively referred to as the transmission cable 60.

[0026] A first input cable 17A and a first output cable 17B are connected to the first main control unit 13A. The first input cable 17A transmits control signals transmitted from a transmission cable 60 to the first main control unit 13A. The first output cable 17B transmits signals such as detection values ​​of various sensors output from the first main control unit 13A to the transmission cable 60.

[0027] Similarly, the second input cable 27A and the second output cable 27B are connected to the second main control unit 23A, and the third input cable 37A and the third output cable 37B are connected to the third main control unit 33A. The second input cable 27A transmits a control signal transmitted through the transmission cable 60 to the second main control unit 23A. The second output cable 27B transmits signals such as detection values ​​of various sensors output from the second main control unit 23A to the transmission cable 60. The third input cable 37A transmits a control signal transmitted through the transmission cable 60 to the third main control unit 33A. The third output cable 37B transmits signals such as detection values ​​of various sensors output from the third main control unit 33A to the transmission cable 60.

[0028] The transmission cable 60 is configured as a multi-core cable in which multiple signal lines capable of transmitting signals in one direction are bundled together. The transmission cable 60 includes a signal line that transmits a control signal output from the general control device 50 to each platform door, and a signal line that transmits signals related to detection values ​​of various sensors output from each platform door. Therefore, in the platform door system 100, a loop circuit is configured with the general control device 50 as its starting point and end point. The general control device 50 transmits control signals to the first main control unit 13A, the second main control unit 23A, and the third main control unit 33A through the transmission cable 60.

[0029] The first main control unit 13A drives the first main drive unit 14A based on a control signal output from the overall control device 50, and controls the opening and closing of the first main door 12A. Specifically, the first main control unit 13A causes the first main drive unit 14A to drive the electric motor based on the control signal output from the overall control device 50, thereby causing the first main door 12A to move forward and backward. At this time, the first main control unit 13A causes the first main drive unit 14A to drive the electric motor based on the position and rotation speed of the electric motor detected by a resolver of the first main drive unit 14A so that the position and speed of the first main door 12A correspond to the command from the overall control device 50.

[0030] In addition, the first main control unit 13A outputs a signal output from the overall control device 50 to the first slave control unit 13B through the first signal line 16. Based on this control signal, the first slave control unit 13B drives the first slave driving unit 14B to control the opening and closing of the first slave door 12B. The second main control unit 23A, the second slave control unit 23B and the third main control unit 33A also control the opening and closing of the door based on a control signal output from the overall control device 50, similar to the first main control unit 13A.

[0031] The overall controller 50 outputs a control signal so that a pair of doors constituting one entrance / exit opens and closes in sync with each other. Specifically, the overall controller 50 outputs various commands as control signals so that the first subsidiary door 12B and the second main door 22A start opening or closing at the same time and operate at the same speed. Similarly, the overall controller 50 outputs various commands as control signals so that the second subsidiary door 22B and the third door 32A start opening or closing at the same time and operate at the same speed.

[0032] The first main control unit 13A, the second main control unit 23A, and the third main control unit 33A output detection values ​​from the various sensors to the general control device 50. For example, the first main control unit 13A outputs, as detection values, to the general control device 50, the vibration of the first door pocket 11 detected by the first main sensor 15A, the internal temperature of the first door pocket 11, the current value supplied to the electric motor constituting the first main drive unit 14A, and the torque applied to the electric motor.

[0033] The first slave control unit 13B outputs, for example, a detection value of an obstacle sensor, a current value supplied to the electric motor constituting the first slave driving unit 14B, and a torque applied to the electric motor as detection values ​​to the first main control unit 13A through the first signal line 16. The first main control unit 13A outputs the various detection values ​​output from the first slave control unit 13B to the overall control device 50. Similarly, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A also output various detection values ​​to the overall control device 50.

[0034] When the integrated control device 50 determines that an abnormality has occurred based on the detection values ​​of various sensors during door opening / closing control, it outputs a control signal for carrying out an abnormality response process. For example, when it is determined that there is an obstacle around the first slave door 12B based on the detection value of the first slave sensor 15B, the integrated control device 50 outputs a command to open the first slave door 12B and the second main door 22A as a control signal for a predetermined period of time as an abnormality response process to the first slave control unit 13B and the second main control unit 23A. After the abnormality response process is completed, the integrated control device 50 outputs a command to open and close the door as normal as a control signal to the first slave control unit 13B and the second main control unit 23A.

[0035] According to the above-described first embodiment, the following effects can be obtained. (1) The first slave control unit 13B can transmit and receive various signals between the general control device 50 and the first master control unit 13A through the first signal line 16. Therefore, both the first master control unit 13A and the first slave control unit 13B can transmit and receive various signals between the general control device 50 and the first master control unit 13A through a pair of cables consisting of the first input cable 17A and the first output cable 17B. According to this configuration, it is possible to omit a cable for connecting the first slave control unit 13B to the transmission cable 60, thereby reducing the number of construction steps and the installation cost of the platform door system 100.

[0036] (2) The first main control unit 13A, the first slave control unit 13B, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A all control the respective doors based on control signals from the overall control device 50. For this reason, the specifications of the first main control unit 13A, the first slave control unit 13B, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A can be unified, thereby reducing manufacturing costs.

[0037] (Embodiment 2) A platform door system 100 according to a second embodiment will be described with reference to Fig. 1. Unless otherwise specified, the same reference numerals denote the same configurations, and detailed descriptions thereof will be omitted as appropriate.

[0038] In the above-mentioned embodiment 1, the general control device 50 outputs a control signal for carrying out the abnormality response process. In contrast, in this embodiment, the first main control unit 13A, the second main control unit 23A, or the third main control unit 33A outputs a control signal for carrying out the abnormality response process.

[0039] The specific control in this embodiment will be described below. In this embodiment, when it is determined that there is an obstacle around the first slave door 12B based on the detection value of the first slave sensor 15B, the first slave control unit 13B outputs a signal to the first main control unit 13A indicating that an obstacle has been detected. The first main control unit 13A outputs information indicating that an obstacle has been detected by the first slave control unit 13B to the second main control unit 23A via the transmission cable 60.

[0040] As an abnormality response process, the second main control unit 23A outputs a control signal to the first slave control unit 13B to command the first slave door 12B to open for a predetermined time period. The control signal is output to the first slave control unit 13B through the transmission cable 60, the first main control unit 13A, and the first signal line 16. When the first slave control unit 13B receives the control signal, it controls the first slave door 12B to open and outputs an open control completion signal indicating that the first slave door 12B has been opened to the second main control unit 23A via the first main drive unit 13A.

[0041] After receiving the open control completion signal, the second main control unit 23A controls the second main door 22A to be open for a predetermined period of time. After the abnormality response process is completed, the second main control unit 23A and the first slave control unit 13B perform normal door opening and closing operations based on the control signal from the general control device 50.

[0042] In this manner, in the abnormality response process of this embodiment, the opening and closing of the first subsidiary door 12B and the second main door 22A is controlled based on the open control completion signal. Therefore, in this embodiment, even when an abnormality occurs, the first subsidiary door 12B and the second main door 22A can be controlled in a synchronized manner.

[0043] According to the above-described second embodiment, in addition to the effect (1) described in the first embodiment, the following effect can be achieved. (3) According to the second embodiment, since the abnormality response process can be performed by each control unit, the processing speed can be improved compared to when the process is performed via the overall control device 50.

[0044] (Embodiment 3) A platform door system 100 according to a third embodiment will be described with reference to Fig. 2. Unless otherwise specified, the same reference numerals denote the same configurations, and detailed descriptions thereof will be omitted as appropriate.

[0045] 2, in the third embodiment, a first input cable 17A is connected to the first main control unit 13A, and a first output cable 17B is connected to the first slave control unit 13B. The first input cable 17A and the first output cable 17B are connected to a transmission cable 60. In the present embodiment, a control signal transmitted from the overall control device 50 through the transmission cable 60 is output to the first main control unit 13A through the first input cable 17A, while various signals output from the first main control unit 13A are output to the transmission cable 60 through the first slave control unit 13B and the first output cable 17B.

[0046] Further, a second input cable 27A is connected to the second main control unit 23A, and a second output cable 27B is connected to the second slave control unit 23B. The second input cable 27A and the second output cable 27B are connected to a transmission cable 60. In this embodiment, a control signal transmitted through the transmission cable 60 is output to the second main control unit 23A through the second input cable 27A, while various signals output from the second main control unit 23A are output to the transmission cable 60 through the second slave control unit 23B and the second output cable 27B. According to the third embodiment, it is possible to achieve an effect similar to that of (1) above.

[0047] (Embodiment 4) A platform door system 100 according to a fourth embodiment will be described with reference to Fig. 3. Unless otherwise specified, the same reference numerals denote the same configurations, and detailed descriptions thereof will be omitted as appropriate.

[0048] The platform door system 100 according to the fourth embodiment has a transmission cable 61 that connects the third main control unit 33A and the overall control device 50. In the above embodiments 1 to 3, the control signals output from the overall control device 50 were transmitted via the transmission cable 60 to the first main control unit 13A, the first slave control unit 13B, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A, and the detection values ​​of the various sensors output from the first main control unit 13A, the first slave control unit 13B, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A were transmitted to the overall control device 50 via the transmission cable 60.

[0049] In contrast, in this embodiment 4, the control signal output from the overall control device 50 is transmitted to the first main control unit 13A, the first slave control unit 13B, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A via the transmission cable 60, as in the above embodiments 1 to 3, but the detection values ​​of the various sensors output from the first main control unit 13A, the first slave control unit 13B, the second main control unit 23A, the second slave control unit 23B, and the third main control unit 33A are transmitted to the overall control device 50 via the transmission cable 61. According to the fourth embodiment, it is possible to achieve an effect similar to that of (1) above.

[0050] (Other embodiments) In the above-mentioned first to fourth embodiments, the transmission cable 60, the first input cable 17A, the first output cable 17B, the second input cable 27A, the second output cable 27B, the third input cable 37A and the third output cable 37B may be made of optical fiber. In the platform door system 100, since it is necessary to perform rapid opening and closing control in accordance with train operations, a high communication speed is required between the general control device 50 and each platform door. According to this modification, the communication speed can be made faster than that of conventional signal lines. Similarly, in the fourth embodiment, the transmission cable 61 may be made of optical fiber.

[0051] In the above-mentioned first and second embodiments, the abnormality response process is executed when an obstacle is detected by the obstacle sensor, but the present disclosure is not limited to this. For example, if the detection value of the torque sensor rises suddenly during the opening and closing control of the door, it is considered that an obstacle is caught, and the abnormality response process can be executed in such a case as well.

[0052] The overall control device 50 can also diagnose whether any phenomenon that could be considered a sign of an abnormality is occurring in the platform door system 100 using detection values ​​from torque sensors, vibration sensors, temperature sensors, etc. [Explanation of symbols]
