DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] In the following embodiments and modifications, the same or equivalent components and members are given the same reference numerals, and duplicated explanations are omitted as appropriate. In addition, the dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. In addition, some of the members that are not important for explaining the embodiments are omitted in each drawing.

[0013] [First embodiment] Please refer to Fig. 1 and Fig. 2. A railcar is provided with a sliding door opening and closing device 1 for opening and closing its entrance / exit. The sliding door opening and closing device 1 includes a pair of left and right sliding doors 10 (10A and 10B), a rail movable body 20, a sliding door rail 30, a drive unit 40, a locking device 50, a door close switch 61, a door lock switch 62, and a door control device 100. The door control device 100 is capable of communicating with a vehicle control device 2 provided in, for example, the driver's cab of the railcar. The door control device 100 of this embodiment is an example of a sliding door position adjustment support device and an information output device.

[0014] The vehicle control device 2 is a higher-level device of the door control device 100, and is configured to be capable of transmitting an opening / closing command signal for controlling the opening and closing of the sliding door 10 to the door control device 100. The vehicle control device 2 of this embodiment is configured to be capable of transmitting a test command signal, which will be described later, to the door control device 100. The vehicle control device 2 of this embodiment is an example of a command device. The vehicle control device 2 and the door control device 100 of this embodiment are an example of a sliding door position adjustment support system.

[0015] A pair of sliding doors 10A and 10B move in opposite directions to open and close the entrance. The sliding doors 10A and 10B in this embodiment are double-opening sliding doors. Each of the sliding doors 10A and 10B is suspended from a rail moving body 20. Each of the sliding doors 10A and 10B is provided with a door end rubber 11 (11A and 11B). When the sliding door 10 is fully closed, the door end rubber 11 is butted against the opposing door end rubber 11 and pressed against it to seal the gap between the door ends of the sliding doors 10A and 10B. Each of the sliding doors 10 is accommodated in a door pocket 12 in the fully open position. A vibration-proof rubber 13 is provided in the gap between the sliding door 10 and the door pocket 12. The vibration-proof rubber 13 holds the sliding door 10 so as to suppress vibration of the sliding door 10.

[0016] The rail movable body 20 includes a door hanger 21 and a resin-made door roller 22. The door hanger 21 has the door roller 22 built in. The door hanger 21 is attached to the sliding door 10 so as to suspend the sliding door 10. The door hanger 21 is attached to a sliding door drive mechanism 42 (described later) of the drive unit 40, and is configured to be movable in the opening and closing direction along the sliding door rail 30 in response to the drive of the drive unit 40.

[0017] The sliding door rail 30 is provided on the vehicle body above the sliding door 10. A door hanger 21 is attached to the sliding door rail 30 via a door roller 22.

[0018] The drive unit 40 includes an electric motor 41 disposed at the upper edge of the entrance / exit of the rail car, and a sliding door drive mechanism 42 composed of a rack, pinion, etc. The motor 41 is connected to the sliding door 10 via the sliding door drive mechanism 42 and the rail movable body 20. When the output shaft of the motor 41 rotates in one direction, the sliding door 10 moves in the opening direction, and when the output shaft of the motor 41 rotates in the other direction, the sliding door 10 moves in the closing direction.

[0019] The locking device 50 has a function of locking a pair of sliding doors 10 in a fully closed state so that they cannot be opened. A locking device 50 is provided for each pair of sliding doors 10. The locking device 50 has a locking pin (not shown) that can be extended and retracted toward the sliding doors 10. The locking pin of the locking device 50 moves to the locked position and is inserted into a hole (not shown) of the sliding door 10 in a fully closed state, thereby locking the sliding door 10 in an unmovable state. However, the locking device 50 is not limited to this, and may lock the sliding door 10 so that it cannot be opened by various known methods.

[0020] The door close switch 61 detects the full closure of the sliding door 10. The door close switch 61 has a limit switch (not shown) for detecting full closure that is pressed by the sliding door 10 when the sliding door 10 moves to the full closed position. When the limit switch for detecting full closure is pressed, the full closure of the sliding door 10 is detected.

[0021] The door close switch 61 of this embodiment detects that the sliding door 10 has moved a predetermined distance from the fully closed position in a direction in which it is pressed against the door tip rubber 11 of the opposing sliding door 10 (hereinafter, the position after this movement is referred to as the "test position"). The door close switch 61 further has a test limit switch that is pressed by the sliding door 10 when the sliding door 10 moves to the test position. When the test limit switch is pressed, it is detected that the sliding door 10 has moved to the test position.

[0022] The door lock switch 62 is a switch that detects the locking of the sliding door 10 by the locking device 50. The door lock switch 62 is composed of a limit switch for lock detection that is pressed by the lock pin of the locking device 50 when the lock pin moves to the locked position. When the limit switch for lock detection is pressed, the locking of the sliding door 10 is detected. The door lock switch 62 is built into the locking device 50, for example.

[0023] The door control device 100 will be described with reference to Fig. 3. Each functional block shown in the following diagram is realized in terms of hardware by a computer having a calculation function, a control function, a storage function, an input function, and an output function, various electronic elements, mechanical parts, etc., and in terms of software by a computer program, etc., but here, functional blocks realized by cooperation of these are depicted. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various forms by combinations of hardware and software.

[0024] The door control device 100 includes a drive control unit 101, a measurement value acquisition unit 102, a measurement value output unit 103, a lock control unit 104, a door entrapment detection unit 105, a lock detection unit 106, and a communication unit 107. The door control device 100 of this embodiment is installed near the sliding doors 10 of all the boarding and alighting doors of one train (see FIG. 1).

[0025] The drive control unit 101 controls the drive unit 40 to move the sliding door 10 in the opening / closing direction. The drive control unit 101 of this embodiment is configured to drive the sliding door 10 further in the closing direction from the fully closed position of the sliding door 10 in response to a test command signal (described later) supplied via the communication unit 107. The drive control unit 101 of this embodiment controls the drive current flowing to the motor 41 of the drive unit 40, thereby controlling the drive of the sliding door 10 in the opening / closing direction.

[0026] The measurement value acquiring section 102 acquires a predetermined measurement value, which will be described later. In this embodiment, the measurement value acquiring section 102 acquires a drive current as a measurement value related to the load.

[0027] The measurement value output unit 103 outputs the measurement value acquired by the measurement value acquisition unit 102. The measurement value output unit 103 in this embodiment outputs the measurement value to an external device such as the vehicle control device 2 via the communication unit 107, and displays the output result on the display screen thereof.

[0028] The lock control unit 104 controls the locking device 50 so as to lock the sliding door 10 when the sliding door 10 is fully closed. The lock control unit 104 locks the sliding door 10 in response to, for example, receiving a lock command signal for locking the sliding door 10 from the vehicle control device 2 via the communication unit 107. The lock command signal is output by the vehicle control device 2 when, for example, the vehicle control device 2 receives a detection signal indicating that the sliding door 10 is fully closed from all the door close switches 61 provided at each entrance. The lock control unit 104 controls the locking device 50 so as to unlock the sliding door 10. Note that the drive control unit 101 may send a command for driving the locking device 50 to the lock control unit 104 in order to control the locking device 50.

[0029] The door entrapment detection unit 105 detects the door entrapment when a foreign object (including a person, a part of a person, and an object) is caught in the door edge of the sliding door 10 and the sliding door 10 cannot be locked (so-called door entrapment state). For example, the door entrapment detection unit 105 detects the door entrapment state when the rotation of the motor 41 is stopped before the sliding door 10 is locked by the locking device 50 during the closing drive of the sliding door 10. The thickness of the object when the door entrapment is detected (hereinafter, referred to as the door entrapment detection thickness) can be adjusted by adjusting the mounting position of the sliding door 10. When the door entrapment detection unit 105 detects the door entrapment, it transmits a door entrapment detection signal via the communication unit 107 to the vehicle control device 2 to notify the door entrapment.

[0030] The lock detection unit 106 detects the locking of the sliding door 10 by the locking device 50. For example, the lock detection unit 106 detects the locking of the sliding door 10 in response to detection of the locking of the sliding door 10 by the door lock switch 62. The thickness of the object when the locking is detected (hereinafter referred to as the lock detection thickness) can be adjusted by adjusting the mounting position of the sliding door 10. When the lock detection unit 106 detects the locking, it transmits a lock detection signal to the vehicle control device 2 via the communication unit 107 to notify the locking.

[0031] The communication unit 107 communicates with an external device. The communication unit 107 of the present embodiment is configured to be able to communicate with the vehicle control device 2.

[0032] The position adjustment work of the sliding door 10 will be described below. The softness (or hardness) of the door end rubber 11, the anti-sway rubber 13, the plastic door roller 22, etc. changes depending on external factors such as the surrounding temperature and humidity. For example, when the outside temperature rises and the door end rubber 11 becomes soft, if the door end rubbers 11A and 11B pinch a foreign object during the closing operation, the door end rubbers 11A and 11B are easily crushed, and the sliding doors 10A and 10B are easily moved closer to each other. In addition, when the anti-sway rubber 13, the door roller 22, etc. become soft, the resistance to the sliding door 10 during the opening and closing operation is reduced, and the sliding doors 10A and 10B are easily moved closer to each other. In this case, even if the door is originally set to detect a foreign object having a thickness of D1 mm, for example, when a foreign object having a thickness of D1 mm is actually pinched, it is assumed that the door will lock without detecting the door pinch. In this way, the door pinch is difficult to detect, which adversely affects the safety of passengers. In addition, when the outside temperature drops and the door end rubber 11 becomes hard, if the door end rubbers 11A and 11B pinch a foreign object during the closing operation, the door end rubbers 11A and 11B are not easily crushed, and the sliding doors 10A and 10B are not easily able to approach each other. In addition, when the anti-vibration rubber 13, the door rollers 22, etc. become hard, the resistance when the sliding door 10 opens and closes increases, and the sliding door 10 is not easily able to approach each other. In this case, even if the door is originally set to lock when a foreign object having a thickness of D2 mm is pinched, it is assumed that the door will not be locked and the door pinch will be detected when a foreign object having a thickness of D2 mm is actually pinched. In this case, the train will not be able to depart when a thin object is caught in the sliding door 10, but will not be able to depart and the door pinch detection will be repeated, adversely affecting regular operation. In this way, depending on the surrounding temperature, humidity, etc., the lock function and the door pinch detection function may not be obtained properly. In order to deal with this, the installation position of the sliding door 10 is adjusted (position adjustment work) for example during safety inspections or every season.

[0033] In this position adjustment work, first, the sliding door opening and closing device 1 is attached to the railway vehicle. Next, a lock adjustment work for adjusting the lock detection thickness and a door entrapment adjustment work for adjusting the door entrapment detection thickness are performed.

[0034] The lock adjustment work will be described. As shown in FIG. 4, in the lock adjustment work, the sliding door 10 is closed while the door clamp adjustment jig 5 is placed on the opening and closing path of the sliding door 10, and when the door clamp adjustment jig 5 of a predetermined thickness is sandwiched between the door end rubbers 11A and 11B, it is determined whether or not the lock is detected. In the case of the lock adjustment work, the door clamp adjustment jig 5 of a thickness for adjusting the lock position is used. If the lock is detected, it is assumed that the lock is properly performed, and the lock adjustment work ends. On the other hand, if the lock is not detected (or if the door is pinched), for example, in the locked state, the mounting position of the sliding door 10 is adjusted. By this work, the relative position between the lock pin (not shown) of the lock device 50 and the hole (not shown) of the sliding door 10 when the door clamp adjustment jig 5 is pinched by the door end rubber 11 is adjusted. As a result, when the door clamp adjustment jig 5 is pinched by the door end rubber 11, the lock pin is inserted into the hole of the sliding door 10 to lock the sliding door 10. Thereafter, it is determined again whether or not the lock is detected using the door clamping adjustment jig 5, and the position adjustment work for the sliding door 10 is repeated until the lock is detected.

[0035] The door clamping adjustment work will be described. In the door clamping adjustment work, the door clamping adjustment work is basically the same as the lock adjustment work, except that a door clamping adjustment jig 5 with a different thickness is used from that in the lock adjustment work. In the door clamping adjustment work, a door clamping adjustment jig 5 with a thickness for door clamping adjustment is used. If door clamping is detected with the door clamping adjustment jig 5 clamped by the door end rubbers 11A and 11B (or if locking is not detected), it is assumed that the door clamping detection is functioning properly, and the door clamping adjustment work ends. On the other hand, if door clamping is not detected (or if locking is detected), the position adjustment work of the sliding door 10 is repeated until door clamping is detected.

[0036] In this manner, the position adjustment is performed so that both the lock and the door entrapment can be appropriately detected.

[0037] However, in the conventional position adjustment work, a worker had to go to all the sliding door opening and closing devices 1, clamp the door clamping adjustment jig 5 with the door tip rubber 11, and determine whether or not the position of the sliding door 10 needed to be adjusted. Therefore, it took a lot of time to check all the sliding doors 10 in one train.

[0038] The present inventors have found that by using the following method, an operator can determine whether or not the position of the sliding door 10 needs to be adjusted without having to go to the trouble of standing in front of the sliding door opening and closing device 1. This method will be described in detail below.

[0039] The operation of the door control device 100 of this embodiment will be described with reference to Fig. 5. Fig. 5 is a flow chart showing the operation S10 for supporting the determination of whether or not the position of the sliding door 10 needs to be adjusted.

[0040] In S11, the drive control unit 101 receives a test command signal from the vehicle control device 2 via the communication unit 107. This test command signal is transmitted from the vehicle control device 2 to the door control device 100 installed at at least one entrance of one train in response to a user input to the vehicle control device 2, for example, during a safety inspection of the sliding door opening and closing device 1 by a railway operator.

[0041] In S12, the drive control unit 101 moves the sliding door 10A and 10B to the fully closed position in response to the test command signal so that the door end rubber 11 contacts the opposing door end rubber 11. Furthermore, the drive control unit 101 moves the sliding door 10 from the fully closed position to the test position by further moving the sliding door 10 a predetermined distance in a direction in which the sliding door 10 is pressed against the opposing door end rubber 11. In this embodiment, when it is detected that the sliding door 10 is located at the test position by pressing the limit switch for testing of the door close switch 61, the drive control unit 101 stops the movement of the sliding door 10 in the pressing direction. In this way, the sliding door 10 is moved to the test position and the door end rubbers 11A and 11B are pressed, simulating a state in which the door end rubbers 11A and 11B are pinched against the door pinching adjustment jig 5.

[0042] In S13, the measurement acquisition unit 102 acquires a measurement value related to the load in the opening direction applied to the sliding door 10 when the sliding door 10 is moved to the test position in S12. Here, as described above, the hardness of the door end rubber 11, the anti-sway rubber 13, the door roller 22, etc. changes depending on external factors such as the surrounding temperature and humidity. In addition, the load in the opening direction applied to the sliding door 10 at the test position changes depending on the hardness of the door end rubber 11, the anti-sway rubber 13, the door roller 22, etc. This is because the hardness of the door end rubber 11 affects the magnitude of the repulsive force when the door end rubber 11 is pressed and crushed, and the hardness of the anti-sway rubber 13, the door roller 22, etc. affects the magnitude of resistance to the sliding door 10 during opening and closing operations. Therefore, by estimating this load in the opening direction, it becomes possible to grasp the ease of movement of the sliding door 10 in the closing direction when the door end rubbers 11A and 11B pinch the door pinch adjustment jig 5. As a result, it becomes possible to grasp the ease of door pinch detection and lock detection, respectively.

[0043] In this embodiment, the drive current of the motor 41 of the drive unit 40 is acquired as the measurement value related to the load. Here, when the load applied to the sliding door 10 increases, the load on the motor 41 used in the drive unit 40 increases, which in turn increases the duty ratio of the drive voltage of the motor 41 and the drive current of the motor 41. Therefore, it is possible to estimate the load applied to the sliding door 10 based on the drive current of the motor 41. The measurement value acquisition unit 102 supplies the acquired measurement value related to the load to the measurement value output unit 103.

[0044] In S14, the measurement value output unit 103 outputs the supplied measurement value to the vehicle control device 2. As a result, the measurement value is displayed on a display unit (not shown) of the vehicle control device 2.

[0045] Then, operation S10 ends.

[0046] As described above, the sliding door opening and closing device 1 of this embodiment outputs a measurement value related to the load applied to the sliding door 10 when the sliding door 10 is driven in a direction to press against the opposing object under a predetermined operating condition with the door end rubber 11 in contact with the opposing object (the opposing door end rubber 11 in this embodiment). The predetermined operating condition of this embodiment is to move the sliding door 10 by a predetermined distance. According to this embodiment, the worker can grasp the ease of movement of the sliding door 10 in the closing direction when the door end rubbers 11A and 11B pinch the door clamping adjustment jig 5, so that this measurement value can be used as a guide for judging whether or not the position of the sliding door 10 needs to be adjusted. Therefore, it becomes possible to judge whether or not the position of the sliding door 10 needs to be adjusted without the worker having to go to the trouble of pinching the door clamping adjustment jig 5 between the door end rubbers 11A and 11B before the sliding door opening and closing device 1. As a result, it becomes unnecessary to check all the sliding doors 10 in one train, so that it becomes possible to reduce the man-hours required for the position adjustment work.

[0047] In this embodiment, the opposing object is a door end rubber (e.g., door end rubber 11B) of one of the sliding doors (e.g., sliding door 10B) when the sliding door 10 is one of the sliding doors of a double-opening door (e.g., sliding door 10A). With this configuration, it is possible to determine the necessity of adjusting the position of the sliding door 10 using the existing configuration without providing a new configuration for crushing the door end rubber 11. The opposing object may be a door stopper.

[0048] In this embodiment, the drive control unit 101 controls the drive current flowing to the motor 41 of the drive unit 40, and the measurement acquisition unit 102 acquires the drive current as a measurement value related to the load. With this configuration, it is possible to determine the necessity of adjusting the position of the sliding door 10 using the existing configuration without providing a new sensor for measuring the measurement value related to the load.

[0049] The sliding door position adjustment support system of this embodiment includes a plurality of door control devices 100 and a vehicle control device 2 that outputs a test command signal to at least one of the plurality of door control devices 100. According to this configuration, since the test command signal can be output to the door control devices 100 collectively, it is possible to collectively determine whether or not the positions of the plurality of sliding doors 10 need to be adjusted. Therefore, it is possible to reduce the workload when determining whether or not the positions of the sliding doors 10 need to be adjusted.

[0050] Modifications of this embodiment will now be described.

[0051] In this embodiment, the sliding door 10 provided on a railway car is taken as an example, but it may also be a sliding door provided on a platform.

[0052] In this embodiment, a double-leaf sliding door 10 is taken as an example, but the present invention is not limited to this and may be a single-leaf sliding door. In the case of a single-leaf sliding door, the opposing object may be, for example, a door stop.

[0053] In the present embodiment, the measured value of the load applied to the sliding door 10 is acquired when the sliding door 10 is moved a predetermined distance with the door end rubber 11 in contact with the opposing object, but the present invention is not limited thereto. For example, the measured value of the moving distance of the sliding door 10 may be acquired when the sliding door 10 is driven in a direction to press against the opposing object so as to apply a predetermined load to the sliding door 10 with the door end rubber 11 in contact with the opposing object. In this case, for example, the measured value of the moving distance of the sliding door 10 may be acquired using a stroke sensor that detects the stroke of the sliding door 10. For example, a plurality of limit switches that are pressed by the sliding door 10 when the sliding door 10 moves toward the closing direction side from the fully closed position may be provided at each position on the closing direction side, and the measured value of the moving distance of the sliding door 10 may be obtained according to the pressed limit switch. Both the measured value of the load and the measured value of the moving distance may be acquired.

[0054] In this embodiment, the drive current of the motor 41 was measured as a measurement value related to the load applied to the sliding door 10, but this is not limiting. For example, a load sensor such as a load cell may be installed in a location (such as the door tip rubber 11) that can be sandwiched between the sliding door 10 and an opposing object, and the measurement value of this load sensor may be used as the measurement value related to the load applied to the sliding door 10. For example, the torque of the motor 41 measured using a torque sensor may be used as the measurement value related to the load applied to the sliding door 10.

[0055] In this embodiment, the driving unit 40 uses an electric motor 41, but an air cylinder that uses compressed air to drive the sliding door 10 in the opening and closing directions may also be used. In this case, a measurement value related to the load is obtained using, for example, a load sensor such as a load cell or a torque sensor.

[0056] In this embodiment, the measurement values ​​are output to the vehicle control device 2, but are not limited to this and may be output to, for example, an external terminal device carried by an operator. The same applies to the comparison results and the determination results of the necessity of position adjustment, which will be described later in the following embodiments.

[0057] In this embodiment, a test limit switch is provided in the door close switch 61 to detect whether the sliding door 10 has reached the test position, but the present invention is not limited to this. For example, a door close switch for detecting full closure and a test door close switch for detecting that the sliding door 10 has reached the test position may be provided in parallel. For example, it may be determined whether the sliding door 10 has reached the test position using a stroke sensor that detects the stroke of the sliding door 10. For example, it may be determined whether the sliding door 10 has reached the test position based on an output signal of an encoder of the motor 41.

[0058] [Second embodiment] A second embodiment of the present invention will be described below. In the drawings and description of the second embodiment, the same or equivalent components and members as those of the first embodiment are denoted by the same reference numerals. Explanations that overlap with the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the first embodiment.

[0059] Please refer to Fig. 6. The door control device 100 of this embodiment further includes a storage unit 108, a reference value setting unit 109, and a comparison result output unit 110. The reference value setting unit 109 of this embodiment is an example of an update unit. The vehicle control device 2 of this embodiment is configured to be able to transmit a first test command signal and a second test command signal, which will be described later, to the door control device 100.

[0060] The operation of the door control device 100 of this embodiment will be described with reference to Fig. 7. Fig. 7 is a flow chart showing the operation S20 for supporting the determination of whether or not the position of the sliding door 10 needs to be adjusted.

[0061] In S21, the drive control unit 101 receives a test command signal from the vehicle control device 2 via the communication unit 107. The test command signal received in S21 is a first test command signal or a second test command signal. The first test command signal is transmitted from the vehicle control device 2 in response to a user input to the vehicle control device 2 after the position adjustment work of the sliding door 10 is completed. The position adjustment work is performed, for example, when the sliding door opening and closing device 1 is equipped on a railway vehicle or when a worker judges it necessary for a safety inspection or the like. The second test command signal is transmitted from the vehicle control device 2 in response to a user input to the vehicle control device 2 when judging, for example, whether or not the position adjustment work is necessary. S22 and S23 are similar to the above-mentioned S12 and S13, and therefore their explanation will be omitted.

[0062] In S24, the measurement value output unit 103 determines whether the test command signal received in S21 is the first test command signal or the second test command signal. If the received test command signal is the first test command signal, the measurement value output unit 103 outputs the supplied measurement value to the reference value setting unit 109, and operation S20 proceeds to S25. If the received test command signal is the second test command signal, the measurement value output unit 103 outputs the supplied measurement value to the comparison result output unit 110, and operation S20 proceeds to S26.

[0063] In S25, the reference value setting unit 109 sets or updates the reference value by storing the supplied measured value in the storage unit 108 as the reference value. Specifically, when the reference value has not yet been set, for example, when the position adjustment is performed when the sliding door opening and closing device 1 is equipped on a railway vehicle, the reference value setting unit 109 sets the measured value as the reference value. When the reference value has already been set, for example, the reference value setting unit 109 updates the reference value using the measured value. Here, the first test command signal is transmitted after the position adjustment work of the sliding door 10 is completed, and the measured value after the completion is set or updated as the reference value in response to the first test command signal. Therefore, the reference value set or updated here indicates a value in a state where the lock function and the door entrapment detection function are appropriately obtained. After S25, the operation S20 ends.

[0064] In S26, the comparison result output unit 110 outputs the comparison result between the supplied measurement value and the reference value predetermined in S25 to the vehicle control device 2 via the communication unit 107. The predetermined reference value is read from the storage unit 108. The comparison result in this embodiment indicates, for example, the difference between the measurement value and the reference value. When the comparison result is output to the vehicle control device 2, the difference as the comparison result is notified. Specifically, the difference is displayed on the display unit of the vehicle control device 2. After S26, operation S20 ends.

[0065] As described above, in this embodiment, the comparison result output unit 110 outputs the comparison result between the output measurement value and the predetermined reference value. With this configuration, by referring to the comparison result of the measurement value against the predetermined reference value, it is possible to grasp the degree of deviation of the measurement value from the reference value, making it easier to determine whether or not position adjustment is necessary.

[0066] In this embodiment, after the position adjustment of the sliding door 10 is completed, the drive control unit 101 controls the drive unit 40 to press the door end rubber 11 against the opposing door end rubber 11 again in S22. The measurement acquisition unit 102 acquires the measurement value when pressed again in S23. The reference value setting unit 109 updates the measurement value when pressed again as the reference value in S25. With this configuration, it is possible to more accurately determine whether or not the position adjustment of the sliding door 10 is necessary, compared to the case where the reference value is held based on the measurement value when the sliding door opening and closing device 1 is equipped, for example.

[0067] In this embodiment, the comparison result output unit 110 notifies the difference between the measured value and the reference value. According to this configuration, for example, when the difference is a positive value (when the measured value is greater than the reference value), it is understood that when the sliding door 10 pinches a foreign object, the sliding door 10 is in a state in which it is easier to move in the closing direction than in the reference state. Therefore, it is understood that the position adjustment work of the sliding door 10 should be performed so that the sliding door 10 is attached on the opening direction side. Similarly, when the difference is a negative value (when the measured value is smaller than the reference value), it is understood that when the sliding door 10 pinches a foreign object, the sliding door 10 is in a state in which it is harder to move in the closing direction than in the reference state. Therefore, it is understood that the position adjustment work of the sliding door 10 should be performed so that the sliding door 10 is attached on the closing direction side. Furthermore, based on the magnitude of the difference, it is possible to grasp to what extent the mounting position of the sliding door 10 should be adjusted to achieve a state in which the lock function and the door pinch detection function are appropriately obtained. From the above, it is possible to reduce the burden during the position adjustment work of the sliding door 10.

[0068] Modifications of this embodiment will now be described.

[0069] The comparison result output unit 110 may use another measurement value measured at the same temperature as when the measurement value was measured as the reference value. In this case, a measurement value may be obtained in advance for each temperature, and the measurement value may be stored in the storage unit 108 in association with each temperature. With this configuration, by referring to the comparison result between the measurement value and the reference value at the same temperature, it is possible to use it as a guide for determining whether or not there is an abnormality in the sliding door opening and closing device 1 (for example, lack of grease or damage to the rollers 22, damage to the pinion gear of the sliding door drive mechanism 42, an abnormality in the motor 41, etc.).

[0070] The comparison result output unit 110 may report the result of a comparison between the air temperature when the measured value was acquired and the air temperature when the measured value used to set or update the reference value in S25 was acquired. According to this configuration, in the position adjustment work, based on the air temperature comparison result, it is possible to know whether the installation position of the sliding door 10 should be adjusted to the opening direction side or the opening direction side depending on whether the air temperature is high or low. As a result, it is possible to reduce the burden of the position adjustment work. The comparison result output unit 110 may output the comparison result of whether the measured value is greater or smaller than the reference value.

[0071] In this embodiment, the reference value is updated in S25. However, the reference value may not be updated and a predetermined reference value, such as a reference value determined using a measurement value when the sliding door opening and closing device 1 is equipped, may be maintained.

[0072] In this embodiment, the comparison result indicates the difference between the measured value and the reference value, but is not limited to this. For example, the comparison result may indicate data in which the measured value and the reference value are arranged side by side.

[0073] [Third embodiment] Hereinafter, a third embodiment of the present invention will be described. In the drawings and description of the third embodiment, the same or equivalent components and members as those of the second embodiment are denoted by the same reference numerals. Explanations that overlap with the second embodiment will be omitted as appropriate, and the configurations that differ from the second embodiment will be described in detail.

[0074] 8, the door control device 100 of the present embodiment further includes a determination result notifying unit 111.

[0075] The operation of the door control device 100 of this embodiment will be described with reference to Fig. 9. Fig. 9 is a flow chart showing the operation S30 for supporting the determination of the necessity of adjusting the position of the sliding door 10. S31 to S35 are the same as S21 to S25 described above, and therefore the description thereof will be omitted.

[0076] In S36, the comparison result output unit 110 outputs the comparison result between the supplied measurement value and the reference value previously determined in S35 to the judgment result notification unit 111. The comparison result in this embodiment is data indicating whether or not the measurement value is within a predetermined range from the reference value. The predetermined range here is set, for example, based on the thickness of the door clamp adjustment jig 5 for the lock adjustment work and the thickness of the door clamp adjustment jig 5 for the door clamp adjustment work. Without being limited thereto, the predetermined range is set appropriately based on the operation method of the sliding door opening and closing device 1, etc.

[0077] In S37, the judgment result notifying unit 111 judges whether or not the position of the sliding door 10 needs to be adjusted based on the comparison result. The judgment result notifying unit 111 of this embodiment judges whether or not the measurement value is within a predetermined range from the reference value. The measurement value is not within the predetermined range from the reference value when, for example, the measurement value exceeds an upper threshold value within a predetermined range from the reference value or falls below a lower threshold value within a predetermined range from the reference value. The measurement value is within the predetermined range from the reference value when, for example, the measurement value is equal to or less than an upper threshold value and equal to or more than a lower threshold value. If the measurement value is not within the predetermined range from the reference value, the judgment result notifying unit 111 judges that the position of the sliding door 10 needs to be adjusted, and the operation S30 proceeds to S38. If the measurement value is within the predetermined range from the reference value, the judgment result notifying unit 111 judges that the position of the sliding door 10 does not need to be adjusted, and the operation S30 proceeds to S39.

[0078] In S38, the judgment result notification unit 111 notifies that the position of the sliding door 10 needs to be adjusted. Specifically, the judgment result notification unit 111 outputs the necessity judgment result indicating that the position of the sliding door 10 needs to be adjusted to the vehicle control device 2 via the communication unit 107. As a result, this necessity judgment result is displayed on the display unit of the vehicle control device 2. After S38, the operation S30 ends.

[0079] In S39, the judgment result notifying unit 111 notifies that it is not necessary to adjust the position of the sliding door 10. Specifically, the judgment result notifying unit 111 outputs the necessity judgment result indicating that it is not necessary to adjust the position of the sliding door 10 to the vehicle control device 2 via the communication unit 107. As a result, this necessity judgment result is displayed on the display unit of the vehicle control device 2. After S39, the operation S30 ends.

[0080] As described above, in this embodiment, the judgment result notifying unit 111 notifies, based on the comparison result, the result of the judgment as to whether or not the position adjustment of the sliding door 10 is necessary. According to this configuration, by notifying the result of the judgment as to whether or not the position adjustment of the sliding door 10 is necessary, it becomes easier to judge whether or not the position adjustment of the sliding door 10 is necessary.

[0081] A modified example of this embodiment will be described. In this embodiment, the necessity of adjusting the position of the sliding door 10 is determined based on whether the measured value is within a predetermined range from the reference value, but this is not limiting. For example, the necessity of adjusting the position of the sliding door 10 may be determined based on whether the difference between the measured value and the reference value is greater than a predetermined threshold value.

[0082] [Fourth embodiment] Hereinafter, a fourth embodiment of the present invention will be described. In the drawings and description of the fourth embodiment, the same or equivalent components and members as those of the third embodiment are denoted by the same reference numerals. Explanations that overlap with the third embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the third embodiment.

[0083] Please refer to FIG. 10. The door control device 100A of this embodiment further includes a request unit 112, an adjacent sliding door information acquisition unit 113, and an adjacent sliding door information notification unit 114. The sliding door 10 controlled to be opened and closed by the door control device 100A is an example of a first sliding door that opens and closes one of a plurality of entrances to a railway vehicle. The sliding door 10 that opens and closes an entrance adjacent to the entrance where the first sliding door 10 is provided is an example of a second sliding door. The adjacent door control device 100B of FIG. 10 controls the opening and closing of the second sliding door 10. The adjacent door control device 100B has the same configuration as the door control device 100A. In this embodiment, it is assumed that a second test command signal is transmitted collectively to the door control device 100A and the adjacent door control device 100B.

[0084] The request unit 112 receives the second test command signal via the communication unit 107, and transmits a request signal to the adjacent door control device 100B in response to the second test command signal, requesting the result of the necessity judgment of the position adjustment. As a result, after the adjacent door control device 100B acquires the necessity judgment result, the adjacent door control device 100B transmits the necessity judgment result. The adjacent sliding door information acquisition unit 113 acquires the necessity judgment result for the second sliding door 10 from the adjacent door control device 100B via the communication unit 107. The adjacent sliding door information acquisition unit 113 supplies the acquired necessity judgment result to the adjacent sliding door information notification unit 114.

[0085] The adjacent sliding door information notification unit 114 judges whether or not the result of the determination as to whether or not the position adjustment of the first sliding door 10 is necessary coincides with the result of the determination as to whether or not the position adjustment of the second sliding door 10 is necessary. If these determination results do not coincide, the adjacent sliding door information notification unit 114 notifies the vehicle control device 2 of the determination result as to whether or not the position adjustment of the second sliding door 10 is necessary via the communication unit 107.

[0086] According to this embodiment, it is possible to prompt the user to check for the presence or absence of an abnormality in the sliding door opening and closing device 1 by using the result of the determination as to whether or not the position adjustment of the second sliding door 10 adjacent to the first sliding door 10 is necessary as reference information.

[0087] Modifications of this embodiment will now be described.

[0088] In this embodiment, the adjacent sliding door information acquisition unit 113 acquires the result of the judgment on the necessity of the position adjustment, but the adjacent sliding door information notification unit 114 may acquire the measurement value for the second sliding door 10. In this case, the adjacent sliding door information notification unit 114 may judge whether the degree of deviation between the measurement value for the first sliding door 10 and the measurement value for the second sliding door 10 exceeds a predetermined range. For example, when the difference or ratio between the measurement values ​​is larger than a predetermined threshold, the adjacent sliding door information notification unit 114 judges that the degree of deviation has exceeded the predetermined range. When it is determined that the degree of deviation has exceeded the predetermined range, the adjacent sliding door information notification unit 114 may notify the measurement value for the second sliding door 10.

[0089] In the present embodiment, an example in which the second test command signal is sent to the door control device 100A and the adjacent door control device 100B at the same time has been shown, but the present invention is not limited to this. For example, the second test command signal may be sent to the door control device 100A without being sent to the adjacent door control device 100B. In this case, the adjacent door control device 100B may simply send the most recently obtained measurement value or necessity determination result in response to the request signal.

[0090] [Fifth embodiment] Hereinafter, the fifth embodiment of the present invention will be described. In the drawings and description of the fifth embodiment, the same or equivalent components and members as those of the first embodiment are denoted by the same reference numerals. Explanations that overlap with the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from the first embodiment.

[0091] Refer to Fig. 11. The door control device 100 of this embodiment further includes a storage unit 108 and a prediction unit 115. In this embodiment, every time a measurement value is supplied from the measurement value acquisition unit 102, the measurement value output unit 103 supplies the measurement value to the storage unit 108 for storage. As a result, the measurement value for each measurement is accumulated in the storage unit 108. The measurement value output unit 103 supplies the measurement value to the prediction unit 115.

[0092] When the measurement value is supplied, the prediction unit 115 reads, for example, the measurement value from the previous measurement from the storage unit 108, and predicts the timing when the position of the sliding door 10 will need to be adjusted based on a comparison between the previous measurement value and the current measurement value. For example, the prediction unit 115 calculates the amount of change over time in the measurement value based on the elapsed time from the previous measurement to the current measurement value and the difference between the previous measurement value and the current measurement value. Based on the calculated amount of change over time, the prediction unit 115 calculates the time until the current measurement value reaches a predetermined threshold value, thereby predicting the above timing.

[0093] As described above, in this embodiment, the prediction unit 115 predicts the timing when the position adjustment of the sliding door 10 will be required based on a comparison between a measurement value acquired at a first time point and a measurement value acquired at a second time point prior to the first time point. According to this embodiment, it is possible to grasp the timing when the position adjustment of the sliding door 10 will be required.

[0094] A modification of this embodiment will now be described.

[0095] In this embodiment, the prediction is based on a comparison between the previous measurement value and the current measurement value, but the present invention is not limited to this and may be based on any measurement value measured before the current measurement value. Also, the prediction may be based on a comparison of three or more measurement values.

[0096] Any combination of the above-described embodiments and modifications is also useful as an embodiment of the present invention. A new embodiment resulting from the combination has the combined effects of the respective embodiments and modifications. [Explanation of symbols]
