Means and effects for solving the problems

An opening / closing control device for a railroad car partition door according to the present invention controls a drive unit that drives to open and close a partition door provided in a railcar vehicle, and controls the drive unit to open and close the partition door. The control unit that detects the presence of a person, a detection switch that transmits a detection signal to the control unit, and the drive that detects and detects the drive amount of the drive unit or the movement amount of the partition door The present invention relates to an opening / closing control device for a railroad car partition door, comprising: a detection unit that sends a survey signal about the amount or the movement amount to the control unit.
And the opening / closing control apparatus of the partition door for rail vehicles which concerns on this invention has the following some features, in order to achieve the said objective. That is, the present invention comprises the following features alone or in appropriate combination.

  In order to achieve the above object, the first feature of the railcar partition door opening / closing control device according to the present invention is that when a fire signal for recognizing the occurrence of a fire is input to the control unit, the control unit The control of the drive unit based on the detection signal of the detection switch is not performed, the drive force by the drive unit is controlled to be reduced, and the partition door is moved by a predetermined amount. When the detection unit detects, the control unit controls the drive unit so that the partition door is driven in the opening direction, and after the predetermined time has elapsed from the start of the control, the control unit Is to control the drive unit so that the partition door is driven in the closing direction.

  According to this configuration, when a fire signal is input, the detection signal of the detection switch is ignored and control of the drive unit is not performed, so the detection switch detects the radiant heat or smoke of the fire and so on. Even if it is transmitted to the control unit, the control for driving the partition door in the opening direction based on the detection signal is not performed. For this reason, it can suppress that a partition door will be in the state opened at the time of fire outbreak, and a fire will spread. Further, when a fire signal is input, control is performed such that the driving force by the driving unit is reduced, so that the holding force in a state where the partition door is closed is reduced. For this reason, when a passenger passes a partition door at the time of a fire outbreak, a partition door can be opened easily with little force. In this state, when a predetermined amount of movement of the partition door is detected, the partition door is driven in the opening direction, and the open state of the partition door is maintained for a predetermined time. For this reason, it can suppress that a passenger's evacuation is prevented. Therefore, it is possible to provide a railcar partition door opening / closing control device capable of suppressing the spread of fire and preventing the passenger from evacuating when a fire occurs in the railcar.

  A second feature of the railcar partition door opening and closing control device according to the present invention is that, when the fire signal is input to the control unit, the control unit drives the partition door in a closing direction. The drive unit is controlled to move the partition door to a fully closed position that is a completely closed state.

  According to this configuration, since the partition door is moved to the fully closed position when a fire occurs, it is possible to suppress the spread of fire due to the partition door being in an open state. Further, by providing the first feature described above, when the partition door is moved, it is driven in the opening direction, so that the evacuation of passengers is prevented from being hindered.

  A third feature of the railcar partition door opening and closing control device according to the present invention is that, when the fire signal is input to the control unit, the control unit is necessary for evacuating passengers of the rail vehicle. The precursor drive unit is controlled so that the partition door is located at a fully opened position for a predetermined time that is set in advance in consideration of time, and then the partition door is closed in the closing direction. The drive unit is controlled so as to be driven, and the partition door is moved to a fully closed position which is a completely closed state.

  According to this configuration, since the partition door is held in the fully open position for a predetermined time when a fire occurs, passengers can be evacuated during that time. And after the predetermined time passes, since the partition door is moved to the fully closed position, it is possible to suppress the spread of fire due to the partition door being opened. Further, by providing the first feature described above, when the partition door is moved, it is driven in the opening direction, so that the evacuation of passengers is prevented from being hindered.

  According to a fourth feature of the railcar partition door opening and closing control device according to the present invention, after the fire signal is input to the control unit, the control unit closes when the partition door is driven in the closing direction. Controlling the drive unit to reduce the directional speed.

  According to this configuration, since the drive speed in the closing direction of the partition door at the time of the occurrence of a fire is reduced, it is possible to prevent a passenger who has rushed from colliding with the partition door at the time of evacuation.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings. The railway vehicle partition door opening / closing control device according to the embodiment of the present invention is used as an opening / closing control device for opening / closing a partition door provided in a railway vehicle. It is used as an open / close control device for a partition door.

  FIG. 1 is a plan view illustrating a railway vehicle (limited express vehicle) 1 to which an opening / closing control device for a railway vehicle partition door according to an embodiment of the present invention is applied, for explaining an outline of the internal structure thereof. It is a top view. The railway vehicle 1 is configured by connecting a plurality of vehicles 2. Each vehicle 2 has, for example, a guest room 3 in which a plurality of seats for passengers are seated, an entrance / exit room 4 used as a space for waiting when passengers go in and out of the vehicle, and the like, and A facility room 5 in which various facilities for use by passengers are arranged. Between the guest room 3 and the entrance / exit room 4 and between the guest room 3 and the facility room 5 are partitioned by a pair of partition walls 7. And the partition door 8 for opening and closing between between this pair of partition walls 7 and 7 is arrange | positioned. The opening / closing operation of the partition door 8 is controlled by the opening / closing control device of this embodiment. A passage 6 is disposed in the center of the guest room 3, and the side walls 9 are formed around the guest room 3, the entrance / exit room 4, and the equipment room 5. In addition, the side door 9 around the entrance / exit chamber 4 is provided with an entrance / exit door 10 that is controlled to be opened and closed for passengers to enter and exit.

  The railcar partition door opening / closing control apparatus according to the present embodiment is applied to the railcar 1 described above. Hereinafter, the opening / closing control device for a railcar partition door according to the present embodiment will be described separately for the first and second embodiments.

(First embodiment)
FIG. 2 illustrates a block diagram of the opening / closing control device 11 (hereinafter simply referred to as the opening / closing control device 11) for a railcar partition door according to the first embodiment of the present invention. The opening / closing control device 11 is disposed, for example, above a partition door 8 provided in the vehicle 2 of the railway vehicle 1. As shown in FIG. 2, the opening / closing control device 11 includes a motor 12, a controller 13, a detection switch 14, and an encoder 15.

  The motor 12 is an electric motor that is driven based on a command from the controller 13, and constitutes a drive unit of this embodiment that drives the door 8 to open and close. Note that a drive pulley, a driven pulley (not shown), and a belt wound around these pulleys are interlocked with the motor 12. The partition door 8 is supported by being suspended by a door hanger (a member for suspension) having a roller, and rolls on the rail with respect to a rail (not shown) disposed above the partition door 8. It is slidably supported via a roller (not shown) of a door hanger. And the door hanger which suspends and supports the partition door 8 is being fixed via the connection metal fitting (not shown) with respect to the belt hung around the pulley mentioned above. By these mechanisms, the partition door 8 is driven to slide along with the rotation of the motor 12, and the pair of partition walls 7 and 7 are opened and closed by the partition door 8.

  The controller 13 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an input / output interface, and the like. And the control part of this embodiment which controls the motor 12 to open and close the partition door 8 is configured. The controller 13 transmits (outputs) a control command of the motor 12 for opening and closing the partition door 8 to a control circuit (not shown) that controls the supply of the drive current of the motor 12, and detects the control command. Signals from the switch 14 and the encoder 15 are received (input). The controller 13 also receives (inputs) a fire signal for recognizing the occurrence of a fire. As this fire signal, for example, detection by a thermal fuse that is provided in the vicinity of the partition door 8 and shuts off a predetermined circuit when the temperature exceeds a predetermined temperature, detection by a thermal sensor or smoke sensor, fire occurrence, etc. It is possible to use a fire detection signal that is generated based on the detection by the operation of the fire detection switch operated by the determined crew or the like.

  The detection switch 14 is configured by, for example, a non-contact sensor such as an ultrasonic type, and transmits (outputs) a detection signal to the controller 13 when the presence of a person is detected. This detection switch 14 is comprised by a pair of transmitter and receiver (not shown) arrange | positioned above the partition door 8, for example, and is each arrange | positioned at the cabin 3 side and the entrance / exit chamber 4 side. Then, the signal emitted from the transmitter is reflected on the floor and received by the receiver to detect the absence of a person, and when this signal is blocked and not received by the receiver, The presence is detected. Thereby, it is possible to detect whether or not a person exists in the vicinity of the partition door 8. In a normal case other than when an abnormality such as a fire occurs, when the presence of a person is detected by the detection switch 14 and the detection signal is input to the controller 13, the controller 13 opens the partition door 8. The drive control of the motor 12 is performed so as to move in the direction (open the partition door 8).

  The encoder 15 is attached to the motor 12 and is composed of a rotary encoder that detects a drive amount of the motor 12, that is, a rotation amount of the motor 12 (a change amount of the rotation angle). The encoder 15 outputs a pulse signal having a pulse number proportional to the rotation amount of the motor 12. That is, the encoder 15 constitutes a detection unit of the present embodiment that measures and detects the drive amount of the motor 12 and sends a survey signal (pulse signal) for the detected drive amount to the controller 13. . Based on the pulse signal input from the encoder 15 to the controller 13, the controller 13 can detect the movement amount (stroke amount) of the partition door 8. Note that the detection unit does not have to measure and detect the drive amount of the motor 12 as in the encoder 15. For example, the detection unit may directly measure and detect the movement amount of the partition door 8. Good.

  Here, drive control of the motor 12 by the controller 13 when a fire occurs will be described. When the aforementioned fire signal for recognizing the occurrence of a fire is input to the controller 13, the controller 13 ignores the detection signal of the detection switch 14 so as not to drive the motor 12 based on the detection signal of the detection switch 14. The process for doing is performed. With this process, when a fire occurs (when a fire signal is input), the detection switch 14 detects a factor other than the presence of a person, such as radiant heat or smoke, and the detection signal is transmitted to the controller 13. However, the controller 13 does not perform control for driving the partition door 8 in the opening direction based on the detection signal. Further, the controller 13 performs a process of ignoring the detection signal of the detection switch 14 and a control for reducing the driving force by the motor 12. With this control, the holding force in a state where the partition door 8 is closed is reduced.

  In addition, when a fire occurs (when a fire signal is input), the controller 13 controls the motor 12 so that the partition door 8 is driven in the opening direction when the partition door 8 moves in a predetermined amount in the opening direction. It comes to control. That is, when the encoder 14 detects a predetermined pulse signal having a pulse number corresponding to a predetermined amount of movement of the partition 8, the controller 13 performs an operation for opening a partition 8 by a person. It is determined that the door 8 has moved a predetermined amount, and the motor 12 is controlled so that the partition door 8 is driven in the opening direction so as to assist the operation of the partition door 8 by a person.

  The controller 13 includes a timer (not shown). Then, after starting the control to move the partition door 8 in the opening direction when the partition door 8 moves by a predetermined amount (after a predetermined pulse signal is detected by the encoder 14), a predetermined time has elapsed. After that, the controller 13 controls the motor 12 so that the partition door 8 is driven in the closing direction. Thereby, when the movement of the predetermined amount of the partition door 8 is detected, the partition door 8 will be maintained in the open state for a fixed time. In the controller 13 of the present embodiment, as will be described later, after the partition door 8 is moved by a predetermined amount in the opening direction and driven in the opening direction, the fully open position in which the partition door 8 is fully opened. It is determined whether or not a predetermined time has elapsed since the timer count was started. The timer count start timing may be a timing when the control in the opening direction of the partition door 8 moved by a predetermined amount is started, or may be a timing when the fully opened position is reached.

  In addition, when a fire signal is input, the controller 13 controls the motor 12 so that the partition door 8 is driven in the closing direction to the fully closed position where the partition door 8 is completely closed. It is designed to be moved. That is, when a fire signal is input, the controller 13 drives the partition 8 in the closing direction until the encoder 14 detects a pulse signal having a pulse number corresponding to the fully closed position of the partition 8. Thus, the motor 12 is controlled. Even when the partition door 8 is moved to the fully closed position, if it is detected that the partition door 8 has moved by a predetermined amount, the drive control in the opening direction is performed as described above.

  Next, the operation of the opening / closing control device 11 having the above-described configuration will be described with reference to FIG. FIG. 3 is a flowchart illustrating a process of controlling the opening / closing operation of the partition door 8 by the opening / closing control device 11 when a fire occurs. When the opening / closing control device 11 is activated and the control of the normal opening / closing operation of the partition door 8 is started (start state), the processing shown in FIG. 3 is started in addition to the processing for controlling the normal opening / closing operation. The In the process shown in FIG. 3, first, in step 101 (hereinafter also referred to as S101; the same applies to other steps), it is determined whether or not a fire signal is input to the controller 13. For example, it is determined whether or not a temperature fuse provided in the vicinity of the partition door 8 is blown and a predetermined circuit is cut off. The process of determining whether or not a fire signal has been input is repeated until a fire signal is input (S101, NO).

  If there is a fire signal input in step 101, that is, if a thermal fuse blown is detected (S101, YES), the controller 13 ignores the detection signal of the detection switch 14. Processing is performed (S102). Next, the controller 13 determines whether or not the partition door 8 is located at the fully closed position based on the pulse signal input from the encoder 15 (S103). If it is determined that it is not in the fully closed position (S103, NO), the controller 12 controls the motor 12 to drive the partition door 8 to move in the closing direction (S104). This driving in the closing direction is performed until the partition door 8 reaches the fully closed position (S103, S104). When the partition door 8 has moved to the fully closed position or has been in the fully closed position from the beginning (S103, YES), control for reducing the driving force by the motor 12 is subsequently performed. Is held in the fully closed position with the reduced holding force (S105).

  After the partition door 8 is held in the fully closed position with the lowered holding force, whether or not the partition door 8 has moved a predetermined amount (for example, 90 mm) based on the pulse signal from the encoder 15, that is, manual operation by a person Thus, it is determined whether or not the partition door 8 has been opened by a predetermined amount (S106). The process of determining whether the partition door 8 has been opened by a predetermined amount by manual operation is continuously performed until the partition door 8 is opened by a predetermined amount (S106, NO).

  If it is determined that the partition door 8 has been opened by a predetermined amount (S106, YES), the controller 12 controls the motor 12 to drive the partition door 8 in the opening direction (S107). The driving in the opening direction is continuously performed until it is determined that the partition door 8 has reached the fully opened position (S108, NO). When it is determined that the partition door 8 has reached the fully open position (S108, YES), a timer count for measuring a predetermined time set in advance is started (S109). The timer count is repeated until a timer-up state in which it is determined that the predetermined time has passed (S110, NO). When the predetermined time elapses and the timer is up (S110, YES), the controller 13 controls the motor 12 to drive the partition door 8 in the closing direction (S104). After step 104, for example, the processing after step 103 is repeated until the power supplied to the open / close control device 11 is cut off.

  As described above, according to the open / close control device 11, when a fire signal is input, the detection signal of the detection switch 14 is ignored and the motor 12 is not controlled. Even if the detection signal is transmitted to the controller 13 by detecting smoke or the like, the control for driving the partition door 8 in the opening direction based on the detection signal is not performed. For this reason, it can suppress that the partition door 8 will be in the open state at the time of fire outbreak, and a fire will spread. Further, when a fire signal is input, the driving force by the motor 12 is controlled so as to decrease, so that the holding force when the partition door 8 is closed is reduced. For this reason, when a passenger passes the partition door 8 at the time of a fire outbreak, the partition door 8 can be easily opened with little force. In this state, when a predetermined amount of movement of the partition door 8 is detected, the partition door 8 is driven in the opening direction, and the open state of the partition door 8 is maintained for a predetermined time. For this reason, it can suppress that a passenger's evacuation is prevented. Therefore, it is possible to suppress the spread of fire and prevent the passenger from evacuating when a fire occurs in the railway vehicle 1.

  Moreover, according to this opening / closing control apparatus 11, since the partition door 8 is moved to a fully closed position at the time of a fire occurrence, it is possible to suppress the spread of fire due to the partition door 8 being in an open state. Even in this case, as described above, when the partition door 8 is moved, the partition door 8 is driven in the opening direction.

(Second Embodiment)
Next, a second embodiment of the present invention will be described. The opening / closing control apparatus for a railcar partition door according to the second embodiment is configured similarly to the opening / closing control apparatus 11 according to the first embodiment, and includes a motor 12, a controller 13, a detection switch 14, and an encoder 15. (See FIG. 2). And also in the opening / closing control apparatus of 2nd Embodiment, when a fire signal is input into the controller 13, the controller 13 processes so that the detection signal of the detection switch 14 may be disregarded, and the driving force by the motor 12 is carried out. Control to lower. Similarly to the first embodiment, when it is detected that the partition door 8 has moved by a predetermined amount by manual operation, the motor 12 is controlled to drive the partition door 8 in the opening direction, and the control start is started. After a predetermined time has elapsed, the motor 12 is controlled so as to drive the partition door 8 in the closing direction.

  However, in the open / close control device of the second embodiment, when the fire signal is input to the controller 13, the controller 13 takes a predetermined time set in advance in consideration of the time required for the passenger to evacuate. During this period, the motor 12 is controlled so that the partition door 8 is located at the fully open position, and after the predetermined time has elapsed, the motor 12 is controlled to drive the partition door 8 in the closing direction and move it to the fully closed position. Therefore, when a fire occurs, the partition door 8 is first held in the fully open position for a certain period of time, and then driven to the fully closed position.

  Further, in the opening / closing control apparatus of the second embodiment, after the fire signal is input to the controller 13, the controller 13 reduces the speed in the closing direction when the partition door 8 is driven in the closing direction. 12 is controlled. That is, in the event of a fire, the speed at which the partition door 8 is driven in the closing direction is set to be lower than the speed at which the partition door 8 is driven in the opening direction. Is being carried out gently.

  Next, the operation of the opening / closing control apparatus of the second embodiment having the above-described configuration will be described with reference to FIG. FIG. 4 is a flowchart illustrating a process for controlling the opening / closing operation of the partition door 8 by the opening / closing control device of the second embodiment when a fire occurs. When the opening / closing control device is activated to start control of the normal opening / closing operation of the partition door 8 (start state), the processing shown in FIG. 4 is started in addition to the processing for controlling the normal opening / closing operation. The In the process shown in FIG. 4, first, in step 201, it is determined whether or not a fire signal is input to the controller 13. For example, it is determined whether or not a fire detection signal is generated due to the operation of a fire detection switch by a crew member who has determined that a fire has occurred. The process of determining whether or not a fire signal has been input is repeated until a fire signal is input (S201, NO).

  If a fire signal is input in step 201 (S201, YES), the controller 12 controls the motor 12 to drive the partition door 8 to move in the opening direction (S202). Subsequently, a timer count is started for measuring that a predetermined time elapses after the driving in the opening direction is started (S203). The timer count is repeated until a timer-up state in which it is determined that the predetermined time has elapsed (S204). Thereby, the partition door 8 is maintained in an open state for a fixed time.

  When a predetermined time elapses after the partition door 8 starts to be driven in the opening direction and the timer is in the up state (S204, YES), a process for causing the controller 13 to ignore the detection signal of the detection switch 14 is performed. Performed (S205). Then, the controller 13 performs setting (slow setting) so that the closing direction speed for driving the partition door 8 in the closing direction is controlled to be lower than the speed for driving in the opening direction ( S206). If the slow setting of the closing direction speed is performed, then the setting for reducing the driving force of the motor 12 in the closing direction of the partition door 8 is performed (S207). Thereby, it sets so that the retention strength at the time of the partition door 8 being located in a fully closed position may fall.

  If the setting for reducing the driving force of the motor 12 in the closing direction of the partition door 8 is made (S207), then the controller 13 controls the motor 12 to move the partition door 8 in the closing direction. Is started (S208). Subsequently, based on the pulse signal from the encoder 15, it is determined whether or not the partition door 8 has moved a predetermined amount (for example, 90 mm), that is, whether or not the partition door 8 has been opened by a manual operation by a person. (S209). When it is determined that the partition door 8 is not opened by a predetermined amount (S209, NO), it is further determined whether or not the partition door 8 has reached the fully closed position (S210). After starting the driving in the closing direction (S208), the partition door 8 is continuously driven in the closing direction until reaching the fully closed position on the condition that the partition door 8 is not opened by a predetermined amount by manual operation. (S210, NO). Then, when the fully closed position is reached (S210, YES), the fully closed position is maintained (S211), and the processes after step 209 are repeated.

  If it is determined in step 209 that the partition door 8 has been opened by a predetermined amount by a manual operation (S209, YES), the motor 12 is controlled to assist the manual operation, and the partition door 8 is moved in the opening direction. Driven (S212). Then, the timer count is started with the start of driving in the opening direction (S213), and the timer count is continued until a predetermined time elapses after the time is up (S214, NO). When the predetermined time has elapsed and the time is up (S214, YES), the motor 12 is controlled to start driving the partition door 8 in the closing direction (S208), and the processing after step 208 is repeated. Become. In step 209, it may be determined that the partition door 8 has been decelerated or stopped during the closing operation of the partition door 8 in conjunction with the opening of the partition door 8 by a predetermined amount. In this case, the partition door 8 can be changed to an opening operation at an earlier stage.

  As described above, in the process shown in FIG. 4, the timer count process (S203) after starting the driving in the opening direction in step 202 is performed before the partition door 8 reaches the fully open position and immediately after the opening direction operation starts. It is supposed to be started. Further, the process of setting to reduce the holding force in the closing direction by reducing the driving force by the motor 12 (S207) ignores the detection signal of the detection switch 14 before the partition door 8 is in the fully closed position. This process is performed after the process (S205). Further, the process of driving in the opening direction when the partition door 8 moves by a predetermined amount (S209, S212) is performed even during the movement in the closing direction before the partition door 8 reaches the fully closed position.

  As described above, according to the opening / closing control device of the second embodiment, when the fire occurs, the partition door 8 is held in the fully open position for a predetermined time, so that passengers can be evacuated during that time. And after the predetermined time passes, since the partition door is moved to the fully closed position, it is possible to suppress the spread of fire due to the partition door being opened. Moreover, since the door 8 is driven in the opening direction when it is moved, it is also possible to prevent passengers from being evacuated. Moreover, according to the opening / closing control apparatus of 2nd Embodiment, since the drive speed of the closing direction of the partition door 8 at the time of fire outbreak is reduced, the passenger who hit at the time of evacuation will collide with the partition door 8. Can be suppressed. In addition, about the part similar to the opening / closing control apparatus 11 of 1st Embodiment in the opening / closing control apparatus of 2nd Embodiment, there can exist the same effect. Therefore, it is possible to suppress the spread of fire and prevent the passenger from evacuating when a fire occurs in the railway vehicle 1.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the first and second embodiments described above, and various design changes can be made as long as they are described in the claims. .
