Japanese Unexamined Patent Publication No. 2019-182252

The present inventor has obtained the following recognition about a platform door system that is installed side by side on a platform of a station and has a plurality of platform door devices that are opened and closed in synchronization with the door of a railway vehicle. Some platform door systems include an individual control panel provided for each of a plurality of platform door devices and a comprehensive control panel that integrates each individual control panel. This comprehensive control panel acquires state information such as the open / closed state generated by the individual control panel of the platform door device, and when the acquired state information indicates all the predetermined states, a signal indicating that the predetermined state is confirmed ( Hereinafter, "status confirmation signal") is output to the vehicle.

For example, after the vehicle arrives at the platform, when the status information indicating the open state is acquired from all the platform door devices, the comprehensive control panel outputs a signal permitting the vehicle to open the vehicle door. Further, when the vehicle departs, when the state information indicating the closed state is acquired from all the platform door devices, the comprehensive control panel outputs a signal permitting the vehicle to close the vehicle door.

However, in this system, when a certain home door device is stopped due to a failure or the like, this device does not generate status information, so the comprehensive control panel that integrates this device cannot output a status confirmation signal and cooperates with this device. Other normal home door devices cannot be used either.

From these, the present inventor has room for improvement in the platform door system described in Patent Document 1 from the viewpoint of enabling other platform door devices to be used when a part of the platform door devices is stopped. I realized that.

The present invention has been made in view of these problems, and an object of the present invention is to provide a technique for enabling the use of other platform door devices in cooperation with the platform door device even when the platform door device is stopped. It is in.

In order to solve the above problems, the platform door device according to an embodiment of the present invention has a drive unit that opens and closes and drives a door constituting an entrance / exit of a platform, a fully open state of the door, a fully closed state of the door, and a movement path of the door. A detection unit that detects a specific state, which is at least one of a state in which there is no obstacle on the top and a state in which there is no abnormality in the drive unit, a wireless communication unit that performs wireless communication with an external operation terminal, and a wireless communication unit. When no signal is received from the operation terminal, the specific state transmission unit and the wireless communication unit that transmit the specific state detected by the detection unit to the comprehensive control panel that controls the opening and closing of the platform door device installed on the platform. Is provided with a simulated state transmission unit that transmits a simulated state that simulates a specific state to the general control panel regardless of the detection result of the detection unit when the user receives a signal from the operation terminal.

It should be noted that any combination of the above, and those in which the components and expressions of the present invention are mutually replaced between methods, devices, programs, temporary or non-temporary storage media on which programs are recorded, systems, and the like are also used. It is effective as an aspect of the present invention.

FIG. 1 is a block diagram showing a platform door system 1 including a platform door device 100. FIG. 2 is a perspective view showing the platform door device 100. FIG. 3 is a block diagram showing an individual control panel 20 and a comprehensive control panel 50 of the platform door device 100.

First, the platform door system 1 will be described. The platform door system 1 includes a plurality of platform door devices 100 and a comprehensive control panel 50. In the following description, when identification is required for explanation, one home door device and the other home door device among the plurality of home door devices 100 are referred to as "A" and "B" at the end of the code. By attaching, they are distinguished from each other. Further, the individual control panel of one platform door device 100A and the individual control panel of the other platform door device 100B are distinguished from each other by adding "A" and "B" to the end of the reference numerals. Therefore, the plurality of platform door devices 100 of the present embodiment include one platform door device 100A having the same configuration and another platform door device 100B.

The plurality of platform door devices 100 are provided on the up line and the down line of the platform of the station, respectively, and are provided at positions corresponding to the vehicle doors of the vehicle 52 when the railway vehicle 52 stops at a predetermined position on the platform. It is placed at each entrance and exit. The platform door device 100 has a door pocket portion 10, a door 12 that moves back and forth from the door pocket portion 10 in the left-right direction, and an individual control panel 20.

One comprehensive control panel 50 is provided on the platform and is connected to each individual control panel 20 of the plurality of platform door devices 100 to control the opening and closing of the platform door devices. The door 12 is opened and closed by the comprehensive control panel 50 via the individual control panel 20. By opening the vehicle door and opening the door 12, passengers can get on and off the vehicle 52, and by closing either the vehicle door or the door 12, passengers are restricted from getting on and off.

The connection between the comprehensive control panel 50 and each individual control panel 20 is made via the first transmission line 41 and the second transmission line 44. The first transmission line 41 and the second transmission line 44 are configured to form a loop between the comprehensive control panel 50 and each individual control panel 20. In this example, forming a loop means forming a circulation transmission path that circulates in order between the general control panel 50 and each individual control panel 20 to transmit information, which are bus connection, parallel connection, and serial. This can be achieved by known connection methods such as connection and series connection.

The comprehensive control panel 50 and each individual control panel 20 can communicate with each other via the first transmission line 41. For example, the comprehensive control panel 50 transmits an opening / closing command signal of the door 12 to each individual control panel 20 via the first transmission line 41. Each individual control panel 20 can transmit a specific state of the platform door device 100 via the second transmission line 44. The specific state will be described later.

The comprehensive control panel 50 and the vehicle 52 can communicate with each other via the vehicle information transmission device 54 and the ground element 53. The vehicle 52 can transmit an open request signal and a closed request signal, which will be described later, to the comprehensive control panel 50. The comprehensive control panel 50 can transmit a fully open confirmation signal and a fully closed confirmation signal, which will be described later, to the vehicle 52.

The operation of the platform door system 1 will be described with reference to FIG. When the vehicle 52 reaches a predetermined position on the platform, the crew member of the vehicle 52 transmits an open request signal for opening the doors 12 of all the platform door devices 100 to the general control panel 50 via the ground element 53 and the vehicle information transmission device 54. do. Upon receiving this open request signal, the comprehensive control panel 50 supplies an open command signal to each individual control panel 20. In response to this open command signal, the individual control panel 20 opens the corresponding door 12 and transmits an open confirmation signal (first specific state described later) to the comprehensive control panel 50. When the comprehensive control panel 50 receives the open confirmation signal from all the individual control panels 20, the comprehensive control panel 50 sends the fully open confirmation signal to the vehicle 52 via the vehicle information transmission device 54 and the ground element 53. Upon receiving this fully open confirmation signal, the crew member of the vehicle 52 opens the vehicle door.

When the vehicle 52 departs from the platform, the crew of the vehicle 52 transmits a closing request signal to the general control panel 50 via the ground element 53 and the vehicle information transmission device 54. Upon receiving this closing request signal, the comprehensive control panel 50 supplies a closing command signal to each individual control panel 20. Each individual control panel 20 closes the corresponding door 12 in response to this closing command signal, and transmits a closing confirmation signal (second specific state described later) to the comprehensive control panel 50. When the comprehensive control panel 50 receives the closing confirmation signals from all the individual control panels 20, the comprehensive control panel 50 sends the fully closed confirmation signal to the vehicle 52 via the vehicle information transmission device 54 and the ground element 53. Upon receiving this fully closed confirmation signal, the crew member of the vehicle 52 closes the vehicle door.

As shown in FIG. 3, the comprehensive control panel 50 includes a state acquisition unit 56, a command control unit 57, and a communication control unit 58. The state acquisition unit 56 acquires a specific state or a simulated state, which will be described later, from the individual control panel 20 via the second transmission line 44. When the command control unit 57 receives an open request signal or a close request signal from the vehicle 52 when the specific state or the simulated state satisfies a predetermined condition, the command control unit 57 transmits the open command signal or the close command signal via the first transmission line 41. The signal is transmitted to the door control unit 26 provided on the individual control panel 20. The door control unit 26 controls the drive unit 14 in response to the open command signal or the close command signal to open and close the door 12. The communication control unit 58 transmits a fully open confirmation signal or a fully closed confirmation signal to the vehicle information transmission device 54 when the specific state or the simulated state satisfies a predetermined condition.

Further, the communication control unit 58 transmits predetermined information to the station office display device 60 provided in the station office via the transmission line 60c. As an example, the station office display device 60 displays the state of the door 12 of the up line and the down line, the content of the failure, and the like based on this information. Further, the communication control unit 58 transmits predetermined information to the general control room display device 62 of the general control room provided at a place away from the station via the external transmission line 62c. As an example, the general control room display device 62 displays the status of the doors 12 of all stations based on this information.

The platform door device 100 will be described with reference to FIGS. 2 and 3. The door pocket portion 10 of the platform door device 100 functions as a door pocket for accommodating the panel-shaped door 12 so as to be able to move forward and backward. The door pocket portion 10 is provided with a drive unit 14 that drives the door 12 to open and close, an electric lock 15, an individual control panel 20, and various sensors. The drive unit 14 includes a motor 14 m that opens and closes the door 12 according to the control of the door control unit 26 of the individual control panel 20. The electric lock 15 is locked so that passengers do not open the door 12 without permission when the door 12 is closed. The electric lock 15 is locked and unlocked according to the control of the door control unit 26 of the individual control panel 20. The electric lock 15 can be unlocked by operating an unlock button (not shown) provided on the door pocket portion 10.

Various sensors will be described with reference to FIG. The platform door device 100 is provided with a door open position sensor 30, a door closed position sensor 31, a drive state sensor 32, and an obstacle sensor 33. The door open position sensor 30 is a sensor that detects whether or not the door 12 is located at the open position. The door closed position sensor 31 is a sensor that detects whether or not the door 12 is located at the closed position. As an example, photoelectric sensors can be used as the sensors 30 and 31.

The door open position sensor 30 is a detection unit of the individual control panel 20 that outputs an on signal when the door 12 is located in the open position (hereinafter referred to as "first specific state") and an off signal in other cases. Supply to 23. The door closed position sensor 31 supplies an on signal to the detection unit 23 in a state where the door 12 is located in the closed position (hereinafter referred to as “second specific state”), and an off signal in other states.

The drive state sensor 32 supplies an on signal to the detection unit 23 in a state where there is no abnormality in the drive unit 14 (hereinafter referred to as “third specific state”), and an off signal in other states. For example, the drive state sensor 32 may be an overload sensor that detects whether or not the drive unit 14 is in an overload state. As the overload sensor, a current sensor that detects the drive current of the motor 14 m may be used, and it may be detected that there is no abnormality when the drive current is within a predetermined range. For example, the drive state sensor 32 may be a safety sensor for detecting door pinching that detects whether or not passengers are in contact with the door end (tip portion) of the door 12. A bumper switch (collision detection switch) may be used as a sensor to detect a door pinch, and it may be detected that there is no abnormality when the bumper switch is off (when passengers are not in contact). The drive state sensor 32 of the present embodiment includes both an overload sensor and a door pinch sensor.

The obstacle sensor 33 supplies an on signal to the detection unit 23 in a state where no obstacle exists in the passage of the door 12 (hereinafter referred to as “fourth specific state”), and an off signal in other states. The obstacle sensor 33 of this example has a plurality of photoelectric sensors, and when the plurality of photoelectric sensors do not detect the obstacle, it detects that there is no abnormality.

The individual control panel 20 will be described with reference to FIG. Each functional block shown in each figure including FIG. 3 can be realized by an electronic element such as a computer CPU or a mechanical component in terms of hardware, and can be realized by a computer program or the like in terms of software. Now, I'm drawing a functional block realized by their cooperation. Therefore, it is understood by those skilled in the art that these functional blocks can be realized in various forms by combining hardware and software.

The individual control panel 20 includes a wireless communication unit 21, a simulated state transmission unit 22, a detection unit 23, a specific state transmission unit 24, a self-holding circuit 25, and a door control unit 26.

(Wireless communication unit)
The wireless communication unit 21 will be described with reference to FIG. FIG. 4 is a circuit diagram showing the periphery of the simulated state transmission unit 22. In this figure, the description of some platform door devices 100B is omitted. The platform door device 100 has a normal operation mode in which a normal opening / closing operation is performed and a stop mode. The stop mode is a mode in which normal operation is stopped in order to inspect, repair, maintain, or the like, for example, the platform door device 100. The simulated state transmission unit 22 performs predetermined communication in the stop mode and does not communicate in the normal operation mode.

The wireless communication unit 21 performs wireless communication with an external operation terminal 35. The wireless communication unit 21 accepts an external operation for switching the platform door device 100 from the normal operation mode to the stop mode. The wireless communication unit 21 of the present embodiment wirelessly communicates with the operation terminal 35. As used herein, wireless communication includes receiving physical actions propagated from the operating terminal 35 in addition to wireless communication in a narrow sense. Examples of this physical action include those using magnetism (for example, magnetic field), those using vibration (for example, sound waves), and those using electromagnetic waves (for example, light and radio waves). These propagation forms include the case where the transmitting side and the receiving side are in contact with each other and the case where they are not in contact with each other.

The wireless communication unit 21 is provided inside the door pocket unit 10 that houses the door 12. In the example of FIG. 2, the wireless communication unit 21 receives a signal from the operation terminal 35 on the vertical surface of the door pocket portion 10 of the door 12. At least a part of the surface of the door pocket portion 10 is composed of a transmissive member through which electromagnetic waves are transmitted. The transmissive member can be made of a non-metal material such as resin. In the example of FIG. 2, the portion of the door pocket portion 10 where the wireless communication portion 21 is provided, and the portion facing the operation terminal 35 is made of a resin-made transmissive member. Further, the wireless communication unit 21 of FIG. 2 is covered with a resin. Therefore, even if it is exposed to wind and rain, there is little deterioration and reliability is improved. In addition, it is possible to make it difficult for a person other than an operator or a worker to recognize the operation unit, and it is easy to prevent troubles due to mischief of passengers. Since it is provided on a vertical surface, it is easy to prevent erroneous operation due to falling objects or temporary objects. The vertical plane referred to here includes, in addition to the vertical plane in a narrow sense, what can be visually recognized as a vertical plane.

In the present embodiment, the operation terminal 35 has a magnet 35m for generating a magnetic field, and the wireless communication unit 21 receives a magnetic field (hereinafter, referred to as “magnetic field signal”) generated by the magnet 35m of the operation terminal 35. .. In this example, the wireless communication unit 21 is a reed switch whose contacts open and close according to the magnitude and direction of the magnetic field generated by the magnet 35m. In particular, the wireless communication unit 21 is a normally open type reed switch having a contact that turns on (closes) when a magnetic field of a predetermined size and direction is received.

(Simulated state transmitter)
The simulated state transmission unit 22 will be described with reference to FIG. When the wireless communication unit 21 receives a magnetic field signal from the operation terminal 35, the simulated state transmission unit 22 switches the home door device 100 from the normal operation mode to the stop mode, and sets a specific state regardless of the detection result of the detection unit 23. The simulated state to be simulated is transmitted to the comprehensive control panel 50. In the present specification, transmitting information to the receiving side includes enabling the receiving side to acquire the information in addition to actively transmitting the information. Therefore, transmitting the simulated state to the comprehensive control panel 50 includes enabling the comprehensive control panel 50 to acquire the simulated state. The simulated state will be described later.

The wireless communication unit 21, the simulated state transmission unit 22, and the self-holding circuit 25 are driven by electric power supplied from the power supply 55 provided in the general control panel 50 via the bus R and the bus S. A DC voltage of 24 V is supplied to the bus R, and the bus S is connected to GND. With this configuration, even when the power supply of the individual control panel 20 cannot be used due to a failure or the like, the wireless communication unit 21, the simulated state transmission unit 22, and the self-holding circuit 25 can be operated.

In the present embodiment, the simulated state transmission unit 22 includes a relay circuit 22r, a notification unit 27, and a release reception unit 22p. The relay circuit 22r has a coil portion 22c and five normally open contact portions P0, P1, P2, P3, and P4 that close when the coil portion 22c is energized. The contact portions P1 to P4 function as a bypass switch described later. Hereinafter, the contact portions P1 to P4 are referred to as bypass switches P1 to P4. The contact unit P0 is connected in parallel to the wireless communication unit 21.

The notification unit 27 notifies the outside that the wireless communication unit 21 has received a signal from the operation terminal 35. The notification unit 27 of this example includes a light emitting element such as an LED connected in parallel to the coil unit 22c, and emits light when the relay circuit 22r is operating. That is, the notification unit 27 notifies that it is in the simulated state. In the example of FIG. 2, the notification unit 27 is provided on the surface of the door pocket unit 10 that houses the door 12. As an example, the notification unit 27 is provided in front of the door pocket unit 10. The release receiving unit 22p is a normally closed type reed switch connected in series to the wireless communication unit 21 and the coil unit 22c.

The self-holding circuit 25 of the simulated state transmission unit 22 continues to operate the relay circuit 22r. The self-holding circuit 25 of the present embodiment includes the contact portion P0 of the relay circuit 22r. The contact portion P0 closes when the relay circuit 22r operates, and continues to supply current from the power supply 55 to the coil portion 22c. Specifically, when the wireless communication unit 21 is turned on (when the reed switch is closed), the coil unit 22c is energized by the electric power of the power supply 55, and the contact unit P0 and the bypass switches P1 to P4 are closed. When the contact portion P0 is closed, the energization of the coil portion 22c is maintained and the contact portion P0 remains closed even if the wireless communication unit 21 is turned off (even if the reed switch is opened). In this state, the platform door device 100 continues the stop mode.

The release receiving unit 22p opens when it receives a magnetic field of a predetermined size and direction, and cuts off the energization of the coil unit 22c. When the energization of the coil portion 22c is cut off, the contact portion P0 is opened, the stop mode is canceled, and the normal operation mode is switched to.

When the wireless communication unit 21 receives a signal from the operation terminal 35, the simulated state transmission unit 22 transmits a simulated state simulating a specific state to the comprehensive control panel 50 regardless of the detection result of the detection unit 23. In this example, the simulated state transmission unit 22 has bypass switches P1 to P4 provided in an electric circuit (specific state transmission unit 24) connected to the general control panel 50, and by closing the bypass switches P1 to P4. , The simulated state is transmitted to the general control panel 50. The simulated state transmission unit 22 includes a relay circuit 22r that closes the bypass switches P1 to P4 in response to the wireless communication unit 21 receiving the magnetic field signal from the operation terminal 35. The simulated operation of the specific state by the bypass switches P1 to P4 will be described later.

(Detector)
The detection unit 23 will be described with reference to FIGS. 3 and 4. Based on the signals supplied from the sensors 30 to 33, the detection unit 23 is in a fully open state of the door 12, a fully closed state of the door 12, a state in which there is no obstacle on the movement path of the door 12, and an abnormality in the drive unit 14. Detects a specific state, which is at least one state without a door. The specific state of the present embodiment includes a first specific state, a second specific state, a third specific state, and a fourth specific state. The detection unit 23 of the present embodiment includes a first detection unit 23a, a second detection unit 23b, a third detection unit 23c, and a fourth detection unit 23d.

The first detection unit 23a detects the first specific state in response to the ON signal of the door open position sensor 30. The second detection unit 23b detects the second specific state in response to the ON signal of the door closing position sensor 31. The third detection unit 23c detects the third specific state according to the ON signal of the drive state sensor 32. The fourth detection unit 23d detects the fourth specific state in response to the ON signal of the obstacle sensor 33.

(Specific state transmitter)
When the wireless communication unit 21 does not receive a signal from the operation terminal 35 (in the case of the normal operation mode), the specific state transmission unit 24 transmits the specific state detected by the detection unit 23 to the comprehensive control panel 50. The specific state transmission unit 24 of the present embodiment includes a first specific state transmission unit 24a, a second specific state transmission unit 24b, a third specific state transmission unit 24c, and a fourth specific state transmission unit 24d.

The first specific state transmission unit 24a is provided in each of the platform door device 100A and the other platform door device 100B. The first specific state transmission unit 24a transmits so that the comprehensive control panel 50 can acquire the first specific state detected by the first detection unit 23a. The first specific state transmission unit 24a is an electric circuit connected to the state acquisition unit 56 of the comprehensive control panel 50. In this example, the first specific state transmission unit 24a is turned off when the first detection unit 23a does not detect the first specific state, and is turned on when the first specific state is detected. Terminal X and terminal Has Y. The terminals X and Y are short-circuited when they are on and non-short-circuited when they are off. Each of the first specific state transmission units 24a is connected in series to form a loop 44a, and both ends of the loop 44a are connected to terminals A0 and A1 of the state acquisition unit 56.

In this specification, the short-circuited state includes a short-circuited state in a narrow sense and a state in which the electric resistance is smaller than the non-short-circuited state within a discriminable range, and the non-short-circuited state can be discriminated in addition to the open state. Including the state where the electric resistance is larger than the short-circuited state in a wide range.

When all the first detection units 23a detect the first specific state, all the first specific state transmission units 24a are closed and the loop 44a is short-circuited. The state acquisition unit 56 determines that when the loop 44a is in the short-circuited state, the doors 12 of all the platform door devices are in the first specific state located in the open position. When one or more of the first detection units 23a have not detected the first specific state, the loop 44a is in a non-short circuit state. The state acquisition unit 56 determines that one or more platform door devices are not in the first specific state when the loop 44a is in the non-short circuit state.

The second specific state transmission unit 24b, the third specific state transmission unit 24c, and the fourth specific state transmission unit 24d (hereinafter referred to as “another transmission unit”) are configured in the same manner as the first specific state transmission unit 24a, and are home. It is provided in each of the door device 100A and the other platform door device 100B. The other transmission unit is an electric circuit connected to the state acquisition unit 56 of the general control panel 50, and has a terminal X and a terminal Y that change to a short-circuit state when a specific state is detected.

All the second specific state transmitters 24b are connected in series to form a loop 44b. Both ends of the loop 44b are connected to terminals B0 and B1 of the state acquisition unit 56. The state acquisition unit 56 determines that when the loop 44b is in the short-circuited state, the doors 12 of all the platform door devices are in the second specific state located at the closed position, and when the loop 44b is in the non-short-circuited state, one or more. It is determined that the door 12 of the door 12 is not located in the closed position.

All third specific state transmitters 24c are connected in series to form a loop 44c. Both ends of the loop 44c are connected to terminals C0 and C1 of the state acquisition unit 56. The state acquisition unit 56 determines that when the loop 44c is in the short-circuited state, the drive units 14 of all the platform door devices are in the third specific state where there is no abnormality, and when the loop 44c is in the non-short-circuited state, one or more. It is determined that the drive unit 14 has an abnormality.

All the fourth specific state transmitters 24d are connected in series to form a loop 44d. Both ends of the loop 44d are connected to terminals D0 and D1 of the state acquisition unit 56. When the loop 44d is in the short-circuited state, the state acquisition unit 56 determines that the loop 44d is in the fourth specific state in which there are no obstacles in the passages of the doors 12 of all the platform door devices, and when the loop 44d is in the non-short-circuited state. It is determined that there is an obstacle in one or more platform door devices.

A simulated operation of a specific state by the bypass switches P1 to P4 will be described. Since one platform door device 100A that is stopped does not transmit a specific state, the other platform door device 100B also becomes inoperable. Therefore, in the present embodiment, bypass switches P1 to P4 for transmitting a simulated state simulating a specific state of the stopped platform door device 100A are provided.

When the bypass switch P1 connected in parallel to the terminal X and the terminal Y of the first specific state transmission unit 24a is closed, a short circuit state is established between the terminals X and Y regardless of the state of the first specific state transmission unit 24a. As a result, the bypass switch P1 transmits a simulated state simulating the first specific state to the terminals A0 and A1 of the state acquisition unit 56, and the state acquisition unit 56 first specifies the first specific state based on the information including the simulated state. Determine the success or failure of the state.

When the bypass switch P2 connected in parallel to the terminal X and the terminal Y of the second specific state transmission unit 24b is closed, a short circuit state is established between the terminals X and Y regardless of the state of the second specific state transmission unit 24b. As a result, the bypass switch P2 transmits a simulated state simulating the second specific state to the terminals B0 and B1 of the state acquisition unit 56, and the state acquisition unit 56 receives the second specific state based on the information including the simulated state. Determine the success or failure of the state.

When the bypass switch P3 connected in parallel to the terminal X and the terminal Y of the third specific state transmission unit 24c is closed, a short circuit state is established between the terminals X and Y regardless of the state of the third specific state transmission unit 24c. As a result, the bypass switch P3 transmits a simulated state simulating the third specific state to the terminals C0 and C1 of the state acquisition unit 56, and the state acquisition unit 56 makes the third specific state based on the information including the simulated state. Determine the success or failure of the state.

When the bypass switch P4 connected in parallel to the terminal X and the terminal Y of the fourth specific state transmission unit 24d is closed, a short circuit state is established between the terminals X and Y regardless of the detection state of the fourth specific state transmission unit 24d. As a result, the bypass switch P4 transmits a simulated state simulating the fourth specific state to the terminals D0 and D1 of the state acquisition unit 56, and the state acquisition unit 56 makes the fourth specific state based on the information including the simulated state. Determine the success or failure of the state.

In this way, the stopped platform door device 100A transmits a simulated state simulating a specific state to the state acquisition unit 56. Therefore, the comprehensive control panel 50 can transmit an open command signal or a close command signal according to the specific state of the other platform door device 100B, and can transmit a fully open confirmation signal or a fully closed confirmation signal. As a result, the other platform door device 100B can operate as usual.

Next, the first control S110 in the stop mode will be described. FIG. 5 is a flowchart showing the first control S110 in the stop mode. In this control, one of the plurality of platform door devices 100, the platform door device 100A, is stopped for inspection, repair, maintenance, and the like, and the other platform door device 100B is operated as usual. The first control S110 is started at the timing when the operation terminal 35 is operated by the worker and the wireless communication unit 21 receives the magnetic field signal from the operation terminal 35 (step S111).

When the wireless communication unit 21 receives the magnetic field signal (Y in step S111), the wireless communication unit 21 closes, a current flows through the coil unit 22c of the relay circuit 22r of the simulated state transmission unit 22, and the contact units P0 and the bypass switches P1 to P4 closes (step S112).

When the contact portion P0 is closed, a current flows through the contact portion P0 to the coil portion 22c of the relay circuit 22r. As a result, the simulated state transmission unit 22 is in the self-holding state, and the contact units P0 and the bypass switches P1 to P4 are maintained in the closed state (step S113).

When the bypass switches P1 to P4 are closed, the terminals X and Y of the first to fourth specific state transmitters 24a, 24b, 24c and 24d are short-circuited, and the general control panel 50 is simulated via the second transmission line 44. Is transmitted (step S114).

The simulated state transmission unit 22 continues to transmit the simulated state while it is in the self-holding state. While the simulated state is transmitted, the worker can perform work such as inspection, repair, and maintenance of the platform door device 100A. When these operations are completed, the worker performs an operation of releasing the self-holding state of the simulated state transmission unit 22 in order to switch from the stop mode to the normal operation mode.

When the operation terminal 35 is operated by the worker and the release receiving unit 22p receives the magnetic field signal from the operation terminal 35, the transmission in the simulated state is stopped (step S115). When the release receiving unit 22p does not receive the magnetic field signal (N in step S115), it returns to the beginning of step S114 and repeats step S115.

When the release receiving unit 22p receives the magnetic field signal (Y in step S115), the release receiving unit 22p opens, the coil unit 22c current is cut off, and the contact units P0 and the bypass switches P1 to P4 open (step S116).

When the bypass switches P1 to P4 are opened, the terminals X and Y of the first to fourth specific state transmission units 24a, 24b, 24c, and 24d are opened, and the transmission in the simulated state is stopped (step S117).

When the transmission in the simulated state is stopped, the first control S110 in the stop mode ends, and the mode shifts to the normal operation mode. If the wireless communication unit 21 does not receive the magnetic field signal (N in step S111), S112 to S117 are skipped. The first control S110 is merely an example, and the order of the steps may be changed, or some steps may be added / deleted / changed.

Next, the second control S210 of the platform door system 1 in the stop mode will be described with reference to FIGS. 1 and 6. FIG. 6 is a flowchart showing the second control S210 in the stop mode. In this control, when one of the plurality of platform door devices 100, the platform door device 100A, transmits a simulated state, and the vehicle 52 reaches a predetermined position on the platform, the other platform door device 100B is normally used. Operate as it is.

The second control S210 is started at the timing when the comprehensive control panel 50 receives the open request signal transmitted from the vehicle 52 by the operation of the crew (step S211).

Upon receiving the open request signal (Y in step S211), the comprehensive control panel 50 supplies the open command signal to the individual control panel 20A and the other individual control panel 20B (step S212).

In response to this open command signal, the other individual control panel 20B opens the corresponding door 12 and transmits the first specific state (open confirmation signal) to the comprehensive control panel 50 (step S213). Specifically, the first specific state transmission unit 24a of the other individual control panel 20B is turned on, and the terminals X and Y are short-circuited.

In parallel with step S213, the individual control panel 20A transmits a first simulated state simulating the first specific state (open confirmation signal) to the comprehensive control panel 50 (step S214). Specifically, when the bypass switch P1 connected in parallel to the terminals X and Y of the first specific state transmission unit 24a of the individual control panel 20A is closed, the terminals X and Y are short-circuited.

Upon receiving the first specific state and the first simulated state, the comprehensive control panel 50 determines that all the doors 12 are located in the open positions, and sends a fully open confirmation signal to the vehicle 52 (step S215). Upon receiving this fully open confirmation signal, the crew member of the vehicle 52 opens the vehicle door.

Specifically, the terminals X and Y of the first specific state transmission unit 24a of the individual control panel 20A and the terminals X and Y of the first specific state transmission unit 24a of the other individual control panel 20B are connected in series and loop. Form 44a (see also FIG. 4). Both ends of the loop 44a are connected to terminals A0 and A1 of the state acquisition unit 56. As described above, when all the terminals X and Y in the loop 44a are short-circuited, the loop 44a is in a short-circuited state, and the state acquisition unit 56 determines that the door 12 of all the platform door devices is located in the open position. As a result, the comprehensive control panel 50 sends a fully open confirmation signal to the vehicle 52.

When the fully open confirmation signal is transmitted, the second control S210 in the stop mode ends. If the general control panel 50 does not receive the open request signal (N in step S211), S212 to S215 are skipped. This second control S210 is merely an example, and the order of the steps may be changed, or some steps may be added / deleted / changed.

Next, the third control S310 of the platform door system 1 in the stop mode will be described with reference to FIGS. 1 and 7. FIG. 7 is a flowchart showing the third control S310 in the stop mode. In this control, when the platform door device 100A of one of the plurality of platform door devices 100 transmits a simulated state, when the vehicle 52 departs from the platform, the other platform door device 100B is operated as usual. ..

The third control S310 is started at the timing when the comprehensive control panel 50 receives the closing request signal transmitted from the vehicle 52 by the operation of the crew (step S311).

Upon receiving the closing request signal (Y in step S311), the comprehensive control panel 50 supplies the closing command signal to the individual control panel 20A and the other individual control panel 20B (step S312).

In response to this closing command signal, the other individual control panel 20B closes the corresponding door 12 and transmits a second specific state (close confirmation signal) to the comprehensive control panel 50 (step S313). Specifically, the second specific state transmission unit 24b of the other individual control panel 20B is turned on, and the terminals X and Y are short-circuited.

In parallel with step S313, the individual control panel 20A transmits a second simulated state simulating the second specific state (closed confirmation signal) to the comprehensive control panel 50 (step S314). Specifically, when the bypass switch P2 connected in parallel to the terminals X and Y of the second specific state transmission unit 24b of the individual control panel 20A is closed, the terminals X and Y are short-circuited.

Upon receiving the second specific state and the second simulated state, the comprehensive control panel 50 determines that all the doors 12 are located at the closed positions, and sends a fully closed confirmation signal to the vehicle 52 (step S315). Upon receiving this fully closed confirmation signal, the crew member of the vehicle 52 closes the vehicle door.

Specifically, the terminals X and Y of the second specific state transmission unit 24b of the individual control panel 20A and the terminals X and Y of the second specific state transmission unit 24b of the other individual control panel 20B are connected in series and loop. Form 44b (see also FIG. 4). Both ends of the loop 44b are connected to terminals B0 and B1 of the state acquisition unit 56. As described above, when all the terminals X and Y in the loop 44b are short-circuited, the loop 44b is in a short-circuited state, and the state acquisition unit 56 determines that the door 12 of all the platform door devices is located in the closed position. As a result, the comprehensive control panel 50 sends a fully closed confirmation signal to the vehicle 52.

When the fully closed confirmation signal is transmitted, the third control S310 in the stop mode ends. If the general control panel 50 does not receive the closing request signal (N in step S311), S312 to S315 are skipped. The third control S310 is merely an example, and the order of the steps may be changed, or some steps may be added / deleted / changed.

Next, the control based on the bypass switch P3 will be described. The state acquisition unit 56 of the comprehensive control panel 50 determines that there is an abnormality in any of the drive units 14 of the plurality of platform door devices 100 when the loop 44c is in the non-short circuit state based on the detection result of the drive state sensor 32. .. In this case, the general control panel 50 stops the operation of each drive unit 14, and causes the station office display device 60 and the general control room display device 62 to display that the drive unit 14 has an abnormality. Workers perform restoration work based on this display.

When the bypass switch P3 is not provided, if one platform door device 100A is stopped, the loop 44c does not become a short-circuit state and the third specific state is not established, so that the other platform door device 100B also becomes inoperable.

Since the third specific state is established, the state acquisition unit 56 determines that all the drive units 14 have no abnormality, and operates the other platform door device 100B as usual.

Next, the control based on the bypass switch P4 will be described. The state acquisition unit 56 of the comprehensive control panel 50 determines that an obstacle exists on any of the movement paths of the plurality of platform door devices 100 when the loop 44d is in the non-short circuit state based on the detection result of the obstacle sensor 33. do. In this case, the comprehensive control panel 50 drives each door 12 in the opening direction, and causes the station office display device 60 and the general control room display device 62 to indicate that there is an obstacle. Workers perform restoration work based on this display.

When the bypass switch P4 is not provided, if one platform door device 100A is stopped, the loop 44d does not become a short-circuit state and the fourth specific state is not established, so that the other platform door device 100B also becomes inoperable. In the present embodiment, when one platform door device 100A is in the stop mode, the bypass switch P4 short-circuits between the terminals X and Y of the fourth specific state transmission unit 24d, so that the loop 44d is short-circuited. Since the fourth specific state is established, the state acquisition unit 56 determines that there are no obstacles on all the movement paths, and operates the other platform door device 100B as usual.
