DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for controlling a movable louver which is mounted on a ceiling of a house or the like to adjust the amount of incident sunlight.

[0002]

2. Description of the Related Art FIG. 2 shows an example of the structure of a movable louver.
3 is controlled by the drive shaft 104 via the drive shaft 104, and the L light shield 105 and the W light shield 10
6 are provided. The motor-equipped channel 102 is used for main control, and is driven and controlled by a push button switch 107 having an open / close and stop button. By pressing the button of the push button switch 107, the louver 100 is opened / closed and stopped in the channels with motors 101 to 103, and the amount of incident light is adjusted.

[0003] Since the movable louver mounted on the ceiling or the like has a large mounting area, a large number of louver units are connected and mounted. FIG. 3 shows an example of the configuration, in which three units are connected by L-connection,
0 is controlled.

[0004]

When a large number of louver units are connected and mounted, if all units do not perform the same operation (direction, speed, wing position) due to the structure of the louver, they are adjacent to each other. The unit's wings come into contact and break. Further, when the wing comes to the stop position, the wing will be damaged unless the operation of the wing is stopped as soon as possible.

For this reason, conventionally, a slight displacement of the wing has been ignored, and limit switches and the like have been attached to the fully open position and the fully closed position of the wing, and the stop position of the wing has been detected by turning on and off the switch. Therefore, it is very difficult to set the mounting position of the limit switch and the like, and there are various problems such as the wings being left unclosed, and the wings being damaged at the stop position without stopping the motor.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a method and an apparatus for controlling a movable louver unit which can surely perform the same operation on a plurality of movable louver units. To provide.

[0007]

FIG. 1 shows a configuration example of the present invention.
, N0, and n motor control units. Each of the motor control units 10 to n0 has a motor 11 to n1 and a tachogenerator (tachometer) as a speed detector connected to the motors 11 to n1. ·generator)
12 to n2 and power outlets 13 to n3 for taking in power. Each of the motor control units 10 to n0 has a motor drive circuit 14 to n4 for driving the motor 11 to n1, and a motor rotation determination circuit 1 for determining the motor rotation based on the output from the tachogenerator 12 to n2.
And communication circuits 16 and 17 for transmitting and receiving signals.
To n6 and n7 and AND circuits AND11 and 12 to A
NDn1 and n2 and OR circuits OR11 to ORn1 are provided. Except that the end connector 30 is connected to the last motor control unit n0, the configuration of the other motor control units is the same.

A control unit 40 comprising a computer is connected to a push button switch 41 and a power outlet 42. The control unit 40 has a control circuit 46 including a CPU and the like, a display 44 for displaying necessary information, and a half-open switch 45 for instructing the louver to be half-open.
And communication circuits 44 and 47 for transmitting and receiving signals. The open signal from the control circuit 46 is provided to the motor drive circuits 14 to n4 via the communication circuits 16 to n6 in the motor control units 10 to n0,
The louver is opened by n1 and the closing signal is similarly supplied to the motor drive circuits 14 to n4 via the communication circuits 16 to n6, and the louver is closed by the motors 11 to n1. The tachogenerators 12 to n2 detect the speeds of the motors 11 to n1, and the signals determined by the motor rotation determination circuits 15 to n5 are input to the motor drive circuits 14 to n4.
The determined binary signal is the AND circuit AND1 of each unit.
2 and ANDn2 and OR circuits OR11 to ORn1. A binary signal corresponding to the power supply of each unit is input to the AND circuits AND11 to ANDn1, and the logical product from the subsequent stage is sequentially given as the other input. AND circuits AND12 to ANDn
In the case of No. 2, a logical product result from the subsequent stage is sequentially provided as the other input, and a logical sum result from the subsequent stage is also sequentially provided as the other input to the OR circuits OR11 to ORn1. Note that "1" is given from the end connector 30 to the AND circuits ANDn1 and n2 at the last stage, and "0" is given to the OR circuit ORn1.

Therefore, the motor control units 10 to n
When power is supplied to all 0s, the output PWS of the most downstream AND circuit AND11 becomes “1”, and becomes “0” when no power is supplied. When all of the motors 11 to n1 are rotating, the output RT1 of the most downstream AND circuit AND12 becomes "1", and when there is at least one motor that is not rotating, "0".
Becomes Conversely, the output RT2 of the OR circuit OR11 becomes "0" when all motors are stopped, and becomes "1" when at least one motor is rotating.

In such a configuration, the operation is shown in FIG.
This will be described with reference to the following flowchart. First, the back counter in the control circuit 46 is set to "0" (step S1), and it is determined whether or not the signal PWS is "1" (step S2). If the signal PWS is "0", a stop command is output. (Step S10), an error is displayed on the display 44 (Step S11). If the signal PWS is "1", it means that power is supplied to all the motor control units 10 to n0, and waits for an operation start command (step S3). The start of the operation is instructed by the push button switch 41. First, it is determined whether or not the half-open command is issued by the half-open switch 45 (step S4). If the half-open command is issued, the process jumps to a half-open routine shown in FIGS. .

If it is not a half-open command in step S4, the operation command is open or closed (step S5).
A motor start process shown in FIG. 7 described below is performed (step S40). After that, the back counter is set to "0" (step S6), and it is determined whether or not the push button switch 41 is a stop command (step S7). If the stop command, a stop process shown in FIG. Perform (Step S
50). If the push button switch 41 is not the stop command, it is determined whether or not the signal PWS is "1" (step S).
8) If "0", return to step S10;
If "1", it is determined whether the signal RT1 is "1" (step S9). If "1", the process returns to step S7. If the signal RT1 is "0", the motor stop processing shown in FIG. 9 described later is performed (step S6).
0) Then, a stop command is output, and the process returns to step S1.

FIGS. 5 and 6 show a half-open routine. When the half-open command is issued, the position of the wings is determined by the half-open timer. Issue a command and issue a stop command at the end of the half-open timer. With the above operation, the half-open position is determined by setting the timer.

FIG. 7 shows a motor start process (step S4).
The example of operation 0) is shown. If all the motors are not started within a predetermined time (for example, 1 second), the routine jumps to the back routine of FIG. When a stop command is issued in step S44, the process jumps to a stop routine shown in FIG. In the case where the position of the louver wing is close to fully open at the time of the open command or close to full close at the time of the close command, a slight displacement of the wing is canceled by the predetermined time. The back process in FIG. 10 is to output a reverse rotation command within a specified time (for example, 1 second) after a stop command is issued, when all motors are not started within a specified time when the motor is started. If the system is normal, all motors start. If there is a motor that does not start, the back count becomes "2" (step S70), and a rotation abnormality is displayed (step S73). And if it starts, after stop processing,
Execute the original operation command. At this time, if the system is normal, all motors start, and if there are motors that do not start, the back count becomes "2", and an indication of abnormal rotation is displayed. Even if the motor does not rotate due to the failure of one unit, there is no displacement of the wing. In the case where the position of the wing is near full open at the time of the open command or close to full close at the time of the close command, the displacement of the wing is canceled twice as much as the start process by the back process.

FIG. 8 shows an example of the operation of the stop process (step S50). If there is a motor that is operating even after the issuance of the stop command, an abnormality display of the controller is performed (step S56). FIG. 9 shows that if the motor does not stop within a predetermined time (for example, one second), an indication of a wing position abnormality is displayed (step S66). When the wing is in the vicinity of the open or closed position, a slight displacement of the wing is canceled by the command time.

[0018]

According to the present invention, it is determined whether or not power is supplied to all the movable louver units, whether or not the motors of all the movable louver units are rotating, and at least one of the movable louver units is driven. Each louver unit is controlled by detecting whether or not the louver unit is rotating. Therefore, the same operation can be surely controlled for a plurality of movable louver units with respect to the direction, the speed, and the position of the wing. Further, since the control system is configured by computer software technology, there is an advantage that high-speed and efficient control can be realized and the system can be easily changed.
