Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment)
FIG. 1 is a block diagram showing a configuration of a door drive control device according to an embodiment of the present invention.
As shown in FIG. 1, each of the door drive control devices 20-1 to 20-8 has the same configuration, and a plurality of (for example, eight) are installed on the upper body of one vehicle to manage the state of the vehicle. The train controller 22 is serially connected to the train by a serial transmission line and a discrete wire. As representative of the first door drive controller 20-1, a position calculator 6 and a speed calculator 7 are connected. And an abnormality detector 8, a drive command calculator 9, a power converter 10, and a communication interface unit 11.

  Further, the door drive control device 20-1 is connected to a linear motor 2 that opens and closes the door 1 and a position detector 5 that detects the position of a movable portion of the linear motor 2 through electric wires 12 and 13. Yes. The door 1 is connected to the movable part of the linear motor 2 by a connecting part 3 and is further combined with a locking device 4 for mechanically fixing the door 1. The opening / closing drive mechanism of the door 1 is the same in the other door drive control devices 20-2 to 20-8, but is omitted in the drawing.

The position detector 5 detects the position and speed of the movable part of the linear motor 2, and outputs this detection signal to the position calculator 6, the speed calculator 7 and the abnormality detector 8 via the electrical wiring 13. The position calculator 6 calculates the position of the door 1 from the detection signal output from the position detector 5. The speed calculator 7 calculates the opening / closing speed of the door 1 from the detection signal output from the position detector 5.
The anomaly detector 8 has detected an anomaly in which one or both of the position and velocity detection signals output from the position detector 5 have a value deviated from a value corresponding to the position and velocity control by a predetermined width. In this case, an abnormality detection signal is output to the drive command calculator 9.

The communication interface unit 11 performs communication interface processing of information signals between the train control device 22 and the drive command calculator 9. Further, a station number setting unit 11a is provided, and station number addresses A1 to A8 corresponding to the mounting positions of the respective doors are set in the station number setting unit 11a according to instructions from the train control device 22, as shown in FIG. ing.
The drive command calculator 9 includes a timer table 9a, an information reading unit 9b, a drive control unit 9c, and a delay timer 9d, and a door opening / closing command signal from the train control device 22 is input via the communication interface unit. The linear motor according to the door position information calculated by the position calculator 6, the door speed information calculated by the speed calculator 7, and the abnormality information of the detection signal detected by the abnormality detector 8. A power supply command to be supplied to 2 is calculated, and the door opening / closing drive is controlled by this power supply command. However, the door opening / closing command signal is transmitted simultaneously from the train control device 22 to each of the door drive control devices 20-1 to 20-8.

As shown in FIG. 3, the timer table 9a stores delay timer values T1 to T8 of each door in association with station number addresses A1 to A8. Each delay timer value T1 to T8 is a time for which the delay timer 9d is operated.
As will be described in detail later, each delay timer value T1 to T8 has a time interval slightly exceeding the outflow time (several tens of ms) of the starting current that flows when opening and closing all the doors. The time is set so that sequential opening and closing are performed. In addition, when the doors are sequentially opened and closed, if the starting current at this time is a current value that does not adversely affect the operation of other equipment such as flickering of fluorescent lamps in the same vehicle, one door at a time Alternatively, it may be set to be opened and closed in units of a plurality of sheets. That is, each delay timer value T1 to T8 is set to a time for controlling the opening / closing drive of each door so that a starting current that adversely affects the operation of other devices other than the door does not flow in the same vehicle.

  When the door opening / closing command signal from the train control device 22 is input via the communication interface unit 11, the information reading unit 9b receives the station number address A1 set in the station number setting unit 11a unless the delay timer 9d is operating. ˜A8 are read, delay timer values T1 to T8 associated with the station number addresses A1 to A8 are read from the timer table 9a, and output to the drive control unit 9c.

The drive control unit 9c operates the delay timer 9d for the time of the delay timer values T1 to T8 read by the information reading unit 9b, and opens and closes the door at the end of the operation. That is, the power supply command is output to the power converter 10.
The power converter 10 supplies power to the linear motor 2 in accordance with the power supply command calculated by the drive command calculator 9. As a result, the door 1 is opened and closed.

Next, the door opening / closing drive control operation by the door drive control devices 20-1 to 20-8 having such a configuration will be described with reference to the flowchart shown in FIG.
However, it is assumed that the delay timer values T1 to T8 are set in the timer table 9a as described in step S4 in FIG. That is, 0 ms is set to the delay timer value T1 associated with the station number address A1 and the delay timer value T2 associated with the station number address A2, and the delay timer value T3 associated with the station number address A3 and the station number address A4. 100 ms is associated with the delay timer value T4 associated with the station number address A5, and 200 ms is associated with the delay timer value T5 associated with the station number address A5 and the delay timer value T6 associated with the station number address A6. Assume that 300 ms is set in the delay timer value T7 and the delay timer value T8 associated with the station number address A8.

Further, the processing of the drive command calculator 9 in steps S1 to S9 of this flowchart is started at a constant cycle (for example, 2 ms cycle).
First, in step S1, when a door opening / closing command is generated from a state in which each door is stopped, that is, in a state in which each door is stopped, a door opening / closing command signal is transmitted from the train control device 22 to each door drive control device. 20-1 to 20-8 when the information is input to the information reading unit 9b, or when the door drive control devices 20-1 to 20-8 are turned on from the off state when the door is open, The determination of whether or not there is an open / close command is Yes.

When this is executed for the first time, the delay timer 9d is not operating, so the determination in step S2 is No.
Thus, in step S3, the information reading unit 9b reads the station number addresses A1 to A8 set in the station number setting unit 11a, and the delay timer values T1 to T1 associated with the station number addresses A1 to A8 are read from the timer table 9a. T8 is read and output to the drive control unit 9c.

In step S5, each delay timer 9d is started by the control of each drive control unit 9c to which each delay timer value T1 to T8 is input. As a result, the timer operation of the delay timer 9d is set in step S6.
However, since the delay timer values T1 and T2 set in the first and second door drive control devices 20-1 and 20-2 are 0 ms, the delay timer 9d is not started. In this way, when the delay timer values T1 and T2 are 0 ms, the drive control unit 9c controls the immediate door opening / closing drive. That is, in the case of this example, the first and second doors are immediately opened / closed when a door opening / closing command is issued from the train control device 22.

  Thereafter, when the next drive command calculator 9 is activated, in step S2, the delay timer 9d of the third to eighth door drive control devices 20-3 to 20-8 is in operation, so step S7 is performed. The timer value is decremented. In step S8, the corresponding drive control unit 9c determines whether or not the delay timer 9d has expired (timer value = 0).

  If it is determined that the time is up as a result of the determination, door opening / closing drive control by the drive controller 9c is started in step S9. At this timing, since the delay timer values T3 and T4 of 100 ms are set in the third and fourth door drive control devices 20-3 and 20-4, the first and second doors are opened and closed. After 100 ms, the third and fourth doors are opened and closed.

Thereafter, similarly, by repeating the processes of steps S1, S2, S7, S8, and S9, the fifth and sixth doors and the seventh and eighth doors are sequentially opened and closed.
As described above, according to the door drive control device of the present embodiment, when the opening / closing command signal for instructing to open / close all the doors arranged in the same vehicle is received from the train control device 22, The control means including the timer table 9a, the information reading unit 9b, the drive control unit 9c, and the delay timer 9d provided in the drive command computing unit 9 is configured so that the time when the starting current flows during the door opening / closing drive does not overlap. The door is controlled to open and close sequentially.

As a result, when receiving an open / close command signal for instructing to open / close all the doors at once, a large starting current does not flow as in the case of opening / closing all the conventional doors at the same time. It is possible to prevent a significant drop in the power supply voltage provided in the system.
Therefore, when all the doors in the same vehicle are driven to open and close, the operation of other devices arranged in the same vehicle can be prevented from being adversely affected by the power supply voltage drop.

In addition, when the control means performs the control to sequentially open and close the doors, the control is performed to sequentially open and close the doors in a time that is as close as possible to the time when the starting current flows.
As a result, the start-up current flows for a few tens of milliseconds, so if you open and close the doors in a time slightly exceeding that time, the doors will be opened and closed so that people do not feel the time shift visually. Can be made.
In addition, when the control means performs control to sequentially open and close the doors, the doors are simultaneously opened and closed. At this time, a current value that adversely affects the operation of other devices other than the doors in the same vehicle. Control was performed to open and close a number of doors that do not allow a starting current to flow simultaneously.
As a result, all doors can be quickly opened and closed while preventing a significant drop in the power supply voltage provided for each vehicle.
