Abstract

PURPOSE:To detect an emergency stop position by providing a first abnormal stop switch at a door body power circuit, while providing a second abnormal stop switch at a power supply circuit to stringing, and a breaker circuit against the occurrence of an error. CONSTITUTION:A sub-control section 10 at each door body 3 issues a drive instruction to a drive means 7, when a double-acting control instruction is outputted from a main control section 11 with a single-double acting selector switch 19 selected at double acting mode, thereby causing the door body 3 to enter double action. Then, the sub-control section 10, upon receipt of an abnormal stop signal from an error detecting means 22, issues an open instruction to the first abnormal stop switch 23 for the emergency stop of the door body 3 and at the same time, sends an error detection signal to the main control section 11. The main control section 11, upon receipt of the signal, sends an abnormal stop signal to all the door body sub-control sections 10, and the first abnormal stop switch 23 is thereby opened for interrupting power supply to the drive means 7. As a result, the door body 3 stops after slight motion.

BACKGROUND OF THE INVENTION Generally,
Some electric door devices of this type are used to open and close a large opening having a frontage width of 200 m (m) when the door device is installed at an entrance of a hangar for an airplane, for example. The electric door device used for such a large opening adopts an overhead wire type power feeding system, and when controlling the movement of the door, a motor that constitutes traveling wheels or drive means, or a power transmission between them is used. It is proposed that an encoder detection method that calculates from the number of rotations of a gear or the like provided on the path is used to detect the movement position of the door body, and based on this, the movement stop control of the door body is controlled.

By the way, when performing such movement control,
When there is an abnormality such as obstacle detection, it is proposed to stop the power supply to the overhead wire type power supply system based on the abnormality detection signal to make an emergency stop. However, even if the power supply to each door is cut off in this way, the door itself moves due to inertia, but since the power supply to the door body position detection means has already been cut off, the door body position detection means Does not count the amount of movement due to inertia, and is in the position detection data state before the power supply was cut off. As a result, when the abnormality is canceled by eliminating obstacles, etc., and the original state is restored, the position detection data is considered to be erroneous by the amount of movement due to the inertia, and data correction is performed one by one. There is a problem in that it must be maintained and inferior in maintainability.

Next, the procedure for controlling the movement of the door body 3 by the main and sub control units 11 and 10 will be described with reference to the flow chart. First, the main control unit 11 performs the control of the main routine shown in FIG. When the main power is turned on (for example, the knife switch is closed) and the initial setting is performed, the single-acting / double-acting switching switch 19 is switched to the single-acting side or the double-acting side, or to either side. It is judged whether there is no neutral state,
When it is determined to be the single-acting side, the single-action control state is set. When it is determined to be the double-acting side, the double-action control state is set to the subroutine control state. It outputs a signal that it is in the double-action control state. Incidentally, the initial setting is such that the second abnormal stop switch 31 is closed. On the other hand, the sub control unit 1
0 is the control of the main routine shown in FIG. 5, but when it is initialized when the second abnormal stop switch 31 is closed and the power is turned on, the remote control signal from the main controller 11 is output. However, it is determined whether the signal is a single-action control state signal, a double-action control state signal, or no signal is input. When it is determined that the single-acting control state signal has been input, the individual door body 3 can be moved based on the operation of the left movement switch 17L and the right movement switch 17R provided on each door body 3. However, these moving switches 17L and 17R are set so that they are closed only when the operator is performing a switch operation on the door body 3. Although details of the single-acting control are omitted here, it goes without saying that the setting may be performed in the same manner as in the present invention when an abnormality is detected as described later.

On the other hand, when the sub-control unit 10 determines that the double-action control state signal is input, the abnormality detection signal is input from the abnormality detection means 22 or the main control unit 1
Whether or not an abnormal stop signal to be described later from 1 is input is determined. If it is determined that no signal is input, it is determined whether or not a double-action control command is input from the main control unit 11. If it is determined that there is a double-action control command, the double-action control command and the door body position detection means are determined. A corresponding control command is output to the driving means 7 based on the detection signal from the door 15, and thereby the door 3
Is controlled to automatically run (self-propelling) to the set position and then stop. Further, when it is determined that the abnormality detection signal is input from the abnormality detection unit 22, the sub control unit 1
0 outputs the abnormality detection signal to the main control unit 11, outputs a notification command to the abnormality notification means 20a, and further outputs an opening command to the first abnormal stop switch 23. Therefore, the power supply to the door body position detection means 15 is set to be cut off, and the power supply to the drive means 7 is set to be cut off. Further, even when it is determined that the abnormal stop signal is input from the main control portion 11, the opening command is output to the first abnormal stop switch 23, and the door body is set in this way. The double-action control of 3 and the abnormal stop are set.

Next, a double-action control routine in the main control section 11 will be described with reference to FIG. Here, it is determined whether or not the abnormality detection signal is input from any one of the door bodies 3, and when it is determined that there is no input, that is, when it is determined to be normal, the double-action operation switch 25 It is determined whether or not an operation signal from the device has been input, and when there is an input, the corresponding double-action control command is output to the door body 3 side as described above. On the other hand, when it is determined that the abnormality detection signal is input, the above-described abnormality stop signal is output to each door body 3, and each door body 3 is stopped based on this, The timer set of the timer circuit incorporated in the main control unit 11 is performed. This timer time t is set to the time until the door body 3 is brought to an emergency stop because the power supply to the drive means 7 is cut off due to the output of the abnormal stop signal. Then, it is determined whether or not this timer time t has elapsed, and when it is determined that the timer time t has elapsed, an opening command is output to the second abnormal stop switch 31 to cut off the power supply to the overhead line 4. As a result, the power supply to all the doors 3 is set to be cut off, and the power-off circuit for abnormal times according to the present invention is configured in this manner. The auxiliary control unit 10 on the door body 3 side has a built-in battery for back-up.
The registered data can be saved (stored) before the power supply to the device is cut off. Further, when the abnormal state is released (solved) and the return switch 26 is operated, the closing command is output to the second abnormal stop switch 31.

In summary, since the present invention is constructed as described above, the door body can be double-acted based on the remote control signal. However, the double-action door body is abnormally detected and an emergency stop is made. In this case, first, the first abnormal stop switch is opened to cut off only the power supply to the driving means, and the power supply to the overhead wire is maintained as it is until the door body is stopped. Is energized.
As a result, the position detection data of the door body by the position detection means is counted until the door body stops, and this is registered and stored. As a result, when the abnormality is canceled by removing obstacles and the like is returned to the original state, the detection value of the position detection means does not deviate and a normal detection value is shown. Therefore, it is not necessary to correct the detection data one by one as in the setting to immediately cut off the power supply to the conventional overhead line when an abnormality detection signal is received.
