Next, the operation of the control unit will be described with reference to the time chart of FIG. First, a case where the vehicle travels from the outer zone to the inner zone in FIG. 1 will be described as an example. In FIG. 4, when the power is turned on, the cylindrical door first rotates in any direction, and when it comes to the neutral position, the closed limit switch is turned on.
48a and stop. Then, when the outside detection switch detects a pedestrian and turns ON 46a, a release command 70a is output to the electric lock driving unit to release the electric lock, and the normal rotation command 66a and the high speed command (high voltage Command 69a is output and the cylindrical door rotates forward (clockwise) at high speed to open the door. With the rotation of the motor, a pulse signal proportional to the rotation angle starts to be output from the encoder. Based on this output, when the cylindrical door is opened to near the fully open position, a brake command 68a, a low speed command (low voltage command) 69
When b is output and decelerated to rotate to the fully open position, the forward rotation command 66a and the speed command 69b are turned off and stopped.

Then, the locking command 70b is output and locked, and the mat timer (second timer means) is operated. When a passerby enters the cylindrical door and moves on the mat switch, the mat switch is turned ON22a. However, while the outside safety switch is ON44a, the following operations are performed to prevent the passerby from being caught in the door. Do not start. When the signal of the external safety switch is turned off and the signal of the mat switch is 0N22a, the open timer (first
Cancel the mat timer with the timer means) is operated, after time T ₁ has elapsed, the reverse rotation instruction 67a is output, is performed closing operation on the basis of the output of the same encoder as in the case of door opening operation door is closed. Then, if the mat timer is not canceled, the mat timer returns to the neutral position is output reverse rotation instruction to the T ₂ hours after counting.

The operation of the mat timer is started by stopping the door opening operation which is a certain automatic operation, and the door opening operation is started by the operation of the outside detection switch which is a start switch. Therefore, the operation of the mat timer is substantially started by the operation of the outside detection switch, and the operation timing of the mat timer may be set to the operation time of the outside detection switch.

Then, the operation delay timer is activated at the end of the closing operation, and the operation delay timer measures T _3.
If the numeric keypad of the collation device is not operated within the time, the mode shifts to the exit mode from the reverse direction, the door is opened again in the original direction, and the passerby is exited. The operation of the operation delay timer is started by the operation of the open timer which is a certain automatic operation and the subsequent stop of the door closing operation, and the operation of the open timer is started by the operation of the mat switch. Therefore, the operation of the operation delay timer is substantially started by the operation of the mat switch, and the operation timing of the operation delay timer may be the operation time of the mat switch.

[0017] Then, when the ten-key of the verification device in the T ₃ hours is operated, the operation grace timer is canceled, the result OK signal 41a matching is output, together with the electric lock is unlocked, the motor A reverse rotation command is output to the drive circuit, and the cylindrical door opens by performing the same operation as the above-described door opening operation in the direction of the inner area. Then, when the passerby leaves from above the mat switch after the full opening, the signal of the mat switch is turned OFF, thereby operating the open timer. Then, the time T measured by the open timer
_{After one} hour, a forward rotation command is output to the motor drive circuit, and the door closing operation is performed in the same manner as the above-described door closing operation. In addition, when the signal of the inner safety switch is ON when the pedestrian leaves, the door closing operation does not start during that time. The operation of the inner detection switch during this period is ignored.

Next, when the vehicle passes from the inner area to the outer area, the operation exactly opposite to the above operation is performed. Therefore, description is omitted.

Next, the operation of the traffic management revolving door controlled by the control unit will be described with reference to the flowchart of FIG. In FIG. 5, when the power is
N is returned to the initial state (step # 8 or # 1).
9). First, the case where the vehicle passes from the outer area to the inner area will be described. When the pedestrian stands at the entrance of the traffic management revolving door, the outside detection switch is turned on, and the cylindrical door starts to open clockwise (step # 1). When the opening reaches the entrance of the outside section while decelerating halfway. Stop (step # 2). Here, if the passerby does not enter the cylindrical door (for example, in the case of chilling out) and the mat switch is not turned on, after a predetermined time elapses by the mat timer, the process proceeds to the closing operation of the exit mode in the reverse direction (step # 17). The cylindrical door returns to the neutral position. Then, when the passerby enters the cylindrical door, the mat switch is turned on, the open timer is operated, and after a predetermined time (0 to 7 seconds) has elapsed, the door starts to close (step ♯).
3) When the opening reaches the neutral position while decelerating on the way, it stops (step # 4). Next, the passerby operates the collation device and is checked whether or not the user is a registrant. When it is determined that the user is a registrant, the process proceeds to the next step. When it is determined that the user is not a registrant, the process proceeds to the exit mode in the reverse direction (step # 16), and the door opens in the original direction. . Further, for example, when the collation device is not operated because the registration card has been forgotten, after a predetermined time (2 to 16 seconds) elapses due to the operation of the operation delay timer, the mode similarly shifts to the exit mode in the reverse direction (step # 16). Further, in this case, if the mat switch is OFF, that is, if the pedestrian lurks in the cylindrical door and is not located on the mat switch, the exit mode completion position in the reverse direction (step # 19). This will be described later.

Next, returning to the original state, if it is determined that the user is a registrant, the exit mode is set, and the cylindrical door starts to open in the direction of the inner area (counterclockwise) (step # 5) and decelerates halfway. When the opening reaches the position of the entrance of the inner area, the operation stops (step # 6). Then, when the passerby exits the cylindrical door and the mat switch is turned off, the open timer operates, and after a predetermined time (0 to 7 seconds) elapses, the cylindrical door starts to close (step # 7), and opens while decelerating halfway. When the section reaches the neutral position, it stops (step # 8). Here, in the cylindrical door which is closing in steps # 7 and # 8,
When a passerby waiting in the inside area enters, the mat switch detects this and turns on, thereby returning to step # 5 and leaving at step # 6. Further, even after the door is closed in step # 8 and a series of operations is completed, if the mat switch is turned on, the process returns to step # 5 in the same manner as described above. In order to prevent a pedestrian who has fallen from the mat switch and lurked in the door from being trapped in the cylindrical door as it is, by moving on the mat switch, the pedestrian can go out on his own will It is like that.

Next, a case where the vehicle passes from the inner area to the outer area will be described. When the pedestrian stands at the entrance of the traffic management revolving door in step # 8 or step # 19, the inner detection switch is turned on, and the cylindrical door rotates counterclockwise (step # 12), and the opening is located at the entrance of the inner area. Is stopped (step # 13). Here, if the passerby is, for example, ridiculed, does not enter the cylindrical door, and does not turn on the mat switch, after a predetermined time has elapsed by the mat timer, the closing operation in the above-mentioned exit mode in the reverse direction (step # 6). Then, the cylindrical door returns to the neutral position and the operation is completed. When a passerby enters the cylindrical door, the mat switch turns on.
After a lapse of a predetermined time N, the cylindrical door rotates clockwise (step # 14), and stops when the opening reaches the neutral position (step # 15). Then, the passerby operates the collation device to check whether or not the user is a registrant. If it is determined that the user is a registrant, the process proceeds to the next step. The mode shifts to the direction exit mode (step # 5), and the door opens in the direction of the original inner area.
Also, when the collation device is not operated, the process similarly proceeds to step # 5 after a predetermined time elapses due to the operation of the operation delay timer. If the passerby lurks inside the cylindrical door and the mat switch is turned off as described above, the process proceeds to the exit mode completion position in the opposite direction (step # 8), and as described above, the passerby You can go out of the cylindrical door by your own will, but you will return to the original inner area in step # 6, you can not pass to the outer area. When it is determined that the user is a registrant, the exit mode is set, and the cylindrical door rotates in the direction of the outer area (step # 16), and stops when the opening reaches the entrance of the outer area (step # 16). # 17). Then, when the passerby exits the cylindrical door and the mat switch is turned off, the cylindrical door rotates counterclockwise after a predetermined time has elapsed (step # 18), and stops when the opening reaches the neutral position, and a series of operations is performed. The operation is completed (step # 19). The operation when the waiting pedestrian enters the cylindrical door on the way is the same as the above-described operation from the outer area to the inner area. In addition, the pedestrian who lurked in the cylindrical door in the above-mentioned step # 4 can be moved from step # 19 to step # 1.
6. After $ 17, you will eventually return to the outer area and cannot pass to the inner area.

Also, during a series of operations (step # 1)
When the power is turned on in steps (0, # 11, steps # 20 to # 22), the operation is performed according to the flowchart from the corresponding step as shown in the figure, and the operation shifts to the initial state.

Also, as shown in FIG.
When the cylindrical door is opened to the outer or inner area at 6,13,17, the cylindrical door is locked by an electric lock and is restricted from rotating in the opposite direction beyond the neutral position. Therefore,
The door cannot be pushed and rotated by hand to pass through to the opposite side.

As described above, when the passerby does not operate the collation device within the time counted by the timer means in steps # 4 and # 15, the passer-in revolving door enters the cylindrical door. Since the door is inverted and opened in the opposite direction to depart the passer-by, it is possible to prevent a person other than the registrant from closing the door.

[0025]

As described above, according to the traffic control revolving door of the present invention, the timer means of the control section measures a predetermined time based on the detection signal of the pedestrian detecting means in the cylindrical door, and the timer time of the timer means is measured. Inside, when the passerby does not operate the collation device, the control unit performs a reversing operation in a direction in which the passer has entered the cylindrical door, so that it is possible to prevent a person other than the registrant from closing the closed door. .
