The power supply command to be supplied to the linear motor 2 is calculated according to the door speed information and the abnormality information of the detection signal detected by the abnormality detector 8, and the door opening / closing drive is controlled by this power supply command. .

However, the data reading confirmation control unit 9c and the drive control unit 9e constitute a control means.
Further, the door opening / closing command signal is transmitted simultaneously from the train control device 22 or a door opening / closing switch (not shown) provided to the vehicle to each door drive control device 20-1 to 20-8. Yes. The door opening / closing command signal is transmitted all at once according to on / off of a door opening / closing switch (not shown) provided in the vehicle.

  As shown in FIG. 2, the data storage unit 9a stores status data D1 to D8 of the first to eighth door drive control devices 20-1 to 20-8 that are all in the same vehicle at addresses A1 to A8. It is stored in the area. The status data D1 to D8 of the first to eighth door drive control devices 20-1 to 20-8 may be abbreviated as the first to eighth status data D1 to D8 hereinafter.

Each status data D1 to D8 indicates the state of the door controlled by the corresponding door drive control device 20-1 to 20-8 by 1 byte (byte) information. All the door drive control devices 20-1 to 20-8 hold all the status data D1 to D8 in common. The status data D1 to D8 are also held in the train control device 22.
These status data D1 to D8 have the same data configuration, and as shown in FIG. 3, they have an 8-bit (1 byte) configuration from 0 to 7 bits. The 0th bit is an LSB (Least Significant Bit), and the 7th bit is an MSB (Most Significant Bit).

The 7-bit data B7 indicates that the door opening operation is being performed when “1”, and that the door opening operation is not performed when “0”.
The 6-bit data B6 indicates that the door closing operation is being performed when “1”, and that the door closing operation is not performed when “0”.
The fifth bit data B5 indicates that the emergency handle is operated when “1”, and indicates the normal state when “0”.

The 4-bit data B4 indicates that a first door error has occurred when “1”, and indicates a normal state when “0”.
The third bit data B3 indicates that a second door error has occurred when “1”, and indicates a normal state when “0”. Note that the first and second door errors represent different malfunctions of the doors defined in advance.

The second bit data B2 indicates that the door is operable when “1”, and indicates that the door is not operable when “0”.
The 1-bit data B1 indicates that the door is stopped in the fully open state when “1”, and indicates the other state when “0”.
The 0-bit data B0 indicates that the door is completely closed and locked when “1”, and indicates the other state when 0.

  Returning to FIG. 1, the data reading confirmation control unit 9 c reads all the status data D1 to D8 stored in the data storage unit 9 a to check the state of all the doors 1, and the status data of the own door (for example, D1) is output to the status transmission / reception unit 9d for transmission to the other door drive control devices 20-2 to 20-8, and the other door drive control devices 20-2 to 20-20 received by the status transmission / reception unit 9d. Status data D2 to D8 from −8 are overwritten in the data storage unit 9a.

  Further, the data reading confirmation control unit 9c determines whether or not the own door 1 is in the open state from the own status data D1 when the close command signal is received, and closes from the other status data D2 to D8 in the open state. It is determined whether the number of other doors in operation is less than the number of simultaneously operable doors set in the simultaneously operable door number setting unit 9b. If the number of doors that can be operated simultaneously is less than the number of doors that can be operated simultaneously, after writing the closing operation of the own door in the own status data D1, the own status data D1 is stored in the other door drive control devices 20-2 to 20-8. And it outputs to the status transmission / reception part 9d in order to transmit to the train control apparatus 22. Furthermore, a door closing operation command is output to the drive control unit 9e.

Furthermore, when the door closing operation control by the drive control unit 9e is completed, the data reading confirmation control unit 9c writes the completion information in the own status data D1, and then uses the own status data D1 for the other door drive control. In order to transmit to the devices 20-2 to 20-8 and the train control device 22, the data is output to the status transmission / reception unit 9d and to the drive control unit 9e.
The simultaneously operable door number setting unit 9b pre-sets and holds the number of doors that can be operated simultaneously in the same vehicle. In this setting, the number of doors is set so that the circuit breaker for protecting the electric circuit of the vehicle does not operate and the circuit is not shut off when the plurality of doors are closed at the same time. It has become.

  When closing the own door according to the set number of doors, in addition to the door that is currently closing, the newly closing doors simultaneously perform multiple closing operations, so that the number of doors that are closing is set to the number of set doors. Is not exceeded. For example, it is performed in the order in which the data reading confirmation control unit 9c reads the status data D1 to D8, or is performed in advance by assigning priorities to each door or each grouped door. This is performed in advance in the data reading confirmation control unit 9c.

The status transmission / reception unit 9d transmits its own status data D1 to the other door drive control devices 20-2 to 20-8 and the train control device 22 via the communication interface unit 11, and the other door drive control device 20-2. To 20-8, other status data D2 to D8 are received via the communication interface unit 11.
Further, the status transmission / reception unit 9d changes all the door drive control devices 20-1 to 20- in cooperation with the data reading confirmation control unit 9c every time the state of the first to eighth status data D1 to D8 changes. 8, control is performed so that all status data D1 to D8 are exchanged (exchanged in a peer-to-peer manner).

The drive controller 9e opens and closes the door according to the content of the status data D1 input from the data reading confirmation controller 9c. This opening / closing drive is performed by outputting a power supply command to the power converter 10.
The power converter 10 is configured to open and close the door 1 by supplying power to the linear motor 2 in accordance with the power supply command calculated by the drive command calculator 9.

  Next, the door 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 number of simultaneously operable doors is set to 4 in the simultaneously operable door number setting unit 9b. The first to fourth door drive control devices 20-1 to 20-4 are set as the first priority group, and the fifth to eighth door drive control devices 20-5 to 20-8 are set as the second priority group. Suppose that

First, assuming that the vehicle body is turned on, all the door drive control devices 20-1 to 20-8 of the vehicle body are energized, so in step S1, it is determined that the vehicle is in the initial state when the power is turned on. .
At this time, when the close command signal is received via the status transmission / reception unit 9d, in step S2, for example, the data reading confirmation control unit 9c of the first door drive control device 20-1 performs the own status from the data storage unit 9a. Data D1 is read, and it is determined whether or not the own door 1 is open.

If it is determined as a result of the determination that the door is in the open state, status data D2 to D8 of other doors are read by the data reading confirmation control unit 9c in step S3.
In step S4, the data reading confirmation control unit 9c determines that the other doors that are being closed from the other status data D2 to D8 are less than the number of doors that can be operated simultaneously set in the simultaneous operation door number setting unit 9b. It is determined whether or not. That is, if the number of set doors is four or more, the processes in steps S3 and S4 are repeated.

  Here, it is assumed that the other doors in the closing operation are the second, third, and fourth units. In this case, since it is determined that the number of set doors is less than 4 in step S4, the own door is closed to B6 of the own status data D1 by the write control of the data reading confirmation control unit 9c in step S5. “1” indicating is written. Then, the self status data D1 after the writing is read and output to the status transmission / reception unit 9d, and the other door drive control devices 20-2 to 20-8 and the communication interface unit 11 from the status transmission / reception unit 9d and It is transmitted to the train control device 22.

The self status data D1 after the writing is also output to the drive control unit 9e. In step S6, the door 1 is closed by the control of the drive control unit 9e according to B1 “1” of the status data D1. Is done.
In step S7, the data reading confirmation control unit 9c determines whether or not the door closing operation control by the drive control unit 9e is completed. As a result, when the door closing operation control is not completed, the door closing operation by the drive control unit 9e is continued.

  On the other hand, if it is determined that the door closing operation has been completed, information on the completion of the door closing operation is written in the status data D1 by the writing control of the data reading confirmation control unit 9c in step S8. That is, B6 of the own status data D1 is set to “0”, and B0 is set to “1”. Then, the self status data D1 after the writing is transmitted to the other door drive control devices 20-2 to 20-8 and the train control device 22 via the status transmission / reception unit 9d, and is output to the drive control unit 9e. .

  Thus, according to the door drive control device of the present embodiment, every time the opening / closing and opening / closing operation state of the door 1 changes according to the control of the drive control unit 9e, the data reading confirmation control unit 9c The change contents are overwritten on the status data D1 of the data storage unit 9a. Furthermore, the status transmission / reception unit 9d transmits the overwritten status data D1 to the other door drive control devices 20-2 to 20-8 via the communication interface unit 11 via the network.

The status data D2 to D8 from the other door drive control devices 20-2 to 20-8 transmitted in this way are controlled by the data reading confirmation control unit 9c together with the status data D1 of the own door drive control device 20-1. Store in the data storage unit 9a. Further, the number of doors that can be operated simultaneously without exceeding the capacity of the power supply is set in the simultaneously operable door number setting unit 9b.
Then, the own door drive control device 20-1 refers to the status data D1 to D8 stored in the data storage unit 9a at the time of receiving the close command signal, and the other door in the closing operation is being opened. When the number of doors is less than the set number, the door is controlled to close.

As a result, when the door drive control devices 20-1 to 20-8 receive the closing command signal for all the doors, the doors do not all close at the same time. It can be closed.
Accordingly, unlike the prior art, all the doors are simultaneously driven to close, a large starting current flows, the power supply voltage is greatly reduced, and the operation of other devices connected to the same power supply is not adversely affected. Furthermore, the circuit breaker for protecting the electric circuit of the vehicle is not operated and the circuit is not interrupted.

Further, as described above, each time the data reading confirmation control unit 9c changes the opening / closing and opening / closing operation state of its own door, the change content is overwritten on the status data D1 stored in the data storage unit 9a, and status transmission / reception is performed. The unit 9d transmits the overwritten status data D1 to the other door drive control devices 20-2 to 20-8.
Thus, every time the opening / closing and opening / closing operation state of the own door changes, the contents of the change are transmitted to the other door drive control devices 20-2 to 20-8, so that all the door drive control devices 20-1 to 20-1. 20-8 can always grasp the state of the other latest door. Therefore, it is possible to close the plurality of doors so as not to exceed the power capacity at all times.
