  FIG. 2 shows the configuration of an embodiment in which the present invention is applied to a shutter opening / closing device. As shown in FIG. 2, the opening / closing device 500 of this embodiment includes a shutter 200 as a movable part (controlled device, opening / closing body), a control device 100 that controls the opening / closing operation of the shutter 200, and a switch 51. Yes. The opening / closing device 500 corresponds to the movable device of the present invention, and the control device 100 corresponds to the control device of the controlled device of the present invention.

The control device 100 includes a control unit (corresponding to the control unit of the present invention) 110 and a photocoupler (corresponding to the operation input detecting unit of the present invention) 101.
The control unit 110 operates by receiving power supply from the AC power supply 50. The control unit 110 is connected to the AC power supply 50 by two power supply wirings 55 and 56, and receives supply of AC power from the AC power supply 50 through these power supply wirings 55 and 56.

  A wiring 57 is connected to the power supply wiring 55 that connects the AC power supply 50 and the control unit 110. The wiring 57 is provided with a switch 51 (corresponding to the switch of the present invention). The other end of the wiring 57 connected to the power supply wiring 55 is connected to the photocoupler 101. In addition, a wiring 58 is connected to the power supply wiring 56 that connects the AC power supply 50 and the control unit 110, and is connected to the photocoupler 101 in the same manner as the wiring 57.

The input side of the photocoupler 101 is connected to power supply wirings 55 and 56 by wirings 57 and 58, respectively. Further, the output side of the photocoupler 101 is connected to the control unit 110 by a wiring 59. The wiring 59 is connected to an input / output unit (shown in FIG. 3) 154 of the control unit 110.
The photocoupler 101 has a general configuration including a light emitting element and a light receiving element (each not shown). Each of the wiring 57 and the wiring 58 is connected to the light emitting element. When the switch 51 is turned on and an alternating current flows through the light emitting element and the light emitting element is turned on, the light receiving element detects the light emission of the light emitting element and outputs a notification signal to the control unit 110 indicating that the switch 51 is turned on. To do. The photocoupler is merely an example, and is not limited thereto. For example, any component or circuit configuration that satisfies the operation, such as a transformer or a relay, may be used.

  The control unit 110 receives the notification signal output from the photocoupler 101, and sends a control signal for controlling the driving of the motor (corresponding to the driving unit of the present invention) 210 to the motor 210. Details of the control unit 110 will be described later with reference to FIGS.

  The shutter 200 is attached to, for example, a window and adjusts the amount of light entering the room by opening and closing. The shutter 200 includes a motor 210 that operates under the control of the control unit 110. By the forward rotation of the motor 210, the shutter 200 performs an opening operation for opening the shutter 200, and by the reverse rotation of the motor 210, the shutter 200 performs a closing operation for closing the shutter 200.

Next, an example of the hardware configuration of the control unit 110 will be described with reference to FIG.
The control unit 110 includes a conversion unit 130, a CPU (Central Processing Unit) 151, a ROM (Read Only Memory) 152, a RAM (Random Access Memory) 153, and an input / output unit 154 as hardware. Note that the configuration of the control unit 110 illustrated in FIG. 3 is merely an example, and is not limited to this configuration.
The converter 130 converts the AC voltage supplied from the AC power supply 50 into a DC voltage, and supplies the converted DC voltage to the CPU 151, ROM 152, RAM 153, and input / output unit 154 via the power supply wiring 131.
The ROM 152 stores a program used by the CPU 151 for control. The CPU 151 reads out the program recorded in the ROM 152, records it in the RAM 153, and performs data processing according to the program recorded in the RAM 153. A procedure in which the CPU 151 processes the data input from the input / output unit 154 in cooperation with the RAM 153 will be described with reference to FIGS.
The RAM 153 is used as a work area of the CPU 151, and stores data used by the CPU 151 for calculation and calculation result data.
The input / output unit 154 inputs a notification signal output from the photocoupler 101 and sends the input signal to the CPU 151. The input / output unit 154 outputs a control signal for the motor 210 sent from the CPU 151 to the motor 210.

FIG. 4 shows functional blocks of the control unit 110 realized by a cooperative operation between the program recorded in the ROM 152 and hardware such as the CPU 151 and the RAM 153. As shown in FIG. 4, the control unit 110 includes a count unit 161, a determination unit 163, and a transmission unit 164 as functional blocks.
The counting unit 161 receives the notification signal transmitted from the photocoupler 101, and counts the number of receptions of the notification signal. The counting unit 161 includes a memory (for example, an internal memory of the CPU 151 or the RAM 153) 162, and records a count value indicating the number of times of receiving the notification signal in the memory 162. Note that the counting means 161 of the present embodiment resets the count value when the count value recorded in the memory 162 reaches four times. Further, when receiving the notification signal from the photocoupler 101, the count unit 161 notifies the determination unit 163 of the reception of the notification signal.
When receiving the notification signal from the counting unit 161, the determining unit 163 refers to the count value in the memory 162 and determines a control signal to be output to the motor 210 according to the count value. The control signal includes a signal for rotating the motor 210 in the forward direction, a signal for rotating the motor 210 in the reverse direction, and a signal for stopping the motor 210.
The transmission unit 164 transmits the control signal determined by the determination unit 163 to the motor 210.
The motor 210 that has received the control signal transmitted from the control unit 110 performs rotation and stop operations in accordance with the control signal, and causes the shutter 200 to open, stop, and close.

Next, the processing procedure of the control unit 110 will be described with reference to the flowchart shown in FIG.
When the power source of the switchgear 500 is turned on (step S1 / YES), the control unit 110 monitors the input port (input / output unit 154) to which the notification signal output from the photocoupler 101 is input, and switches 51 It is determined whether or not has been operated (step S2). If the notification signal output from the photocoupler 101 is input and it is determined that the switch 51 has been operated (step S2 / YES), the control unit 110 first adds 1 to the value of the counter that counts the number of operations of the switch 51. (Step S3). Then, the control unit 110 controls the motor 210 based on the count value of the counter. When the count value of the counter is 1 (step S4 / YES), the control unit 110 sends a control signal for rotating the motor 210 forward to the motor 210 (step S5), and opens the shutter 200. Thereafter, the control unit 110 monitors the operation input of the switch 51, and if there is no operation input of the switch 51 until the shutter 200 is fully opened (step S6 / NO and S7 / YES), the control unit 110 The counter value is incremented by 1 (step S8), and when the count value becomes 2, the control unit 110 stops the motor 210 (step S9). Whether the shutter 200 has been opened to the fully open position is determined by, for example, recording the number of rotations of the motor from the fully closed state to the fully opened state in the memory 162 and detecting the number of rotations of the motor. Thus, the fully open position or the fully closed position may be determined. Alternatively, a sensor may be provided at the fully open position or the fully closed position, and a sensor signal from the sensor may be input to determine the fully open position or the fully closed position. Also, when an operation input of the switch 51 is detected before the shutter 200 is fully opened (step S7 / NO and step S6 / YES), the control unit 110 adds 1 to the counter value (step S8). When the count value becomes 2, the control unit 110 stops the motor 210 (step S9). Thereafter, the control unit 110 determines whether or not the power of the switchgear 500 is turned off (step S17). If the power is not turned off (step S17 / NO), the control unit 110 returns to step S2 and operates the switch 51. Monitor input.

  Further, when the count value of the counter becomes 3 as a result of adding 1 to the count value in step S3 (step 10 / YES), the control unit 110 sends a control signal for reversely rotating the motor to the motor 210 (step S11). ), The shutter 200 is closed. That is, an operation of closing the open shutter 200 is performed. After that, the control unit 110 monitors the operation input of the switch 51, and when there is no operation input of the switch 51 until the shutter 200 is fully closed (step 12 / NO and step S13 / YES), the control unit 110 adds 1 to the counter value (step S14), and stops the motor 210 when the count value becomes 4 (step S15). Thereafter, the control unit 110 resets the count value of the counter (step S16). That is, the counter value is set to zero. Therefore, when the switch 51 is operated next time, the shutter 200 starts operating from the opening operation. Also, when an operation input of the switch 51 is detected before the shutter 200 is fully closed (step S13 / NO and step S12 / YES), the control unit 110 adds 1 to the counter value (step S14). ) When the count value becomes 4, the control unit 110 stops the motor 210 (step S15) and resets the count value of the counter (step S16). Thereafter, the control unit 110 determines whether or not the power of the switchgear 500 is turned off (step S17). If the power is not turned off (step S17 / NO), the control unit 110 returns to step S2 and operates the switch 51. Monitor input. In step S10, when the count value of the counter is not 3 (step S10 / NO), the control unit 110 resets the counter (step S16).

  Note that the processing procedure of the control unit 110 described above is an example, and the present invention is not limited to this. For example, the control unit 110 counts the number of operations of the switch 51 that receives an input within a unit time (for example, 1 to 3 seconds), and opens, closes, and stops the shutter 200 according to the count value. It may be a thing to make. Further, the switch may be closed or opened by long pressing the switch regardless of the count value up to that time.

As apparent from the above description, in this embodiment, the switch 51 is connected to the power supply wiring 55 that supplies power from the AC power supply 50 to the control unit 110, and the operation of the switch 51 is performed by the AC power supplied from the power supply wiring 55. Therefore, it is not necessary to separately provide power supply wiring for supplying power to the switch 51, and the number of wirings can be reduced. For this reason, in the past, two wiring installation work had to be performed in the wall surface or the like. However, since the power supply wiring 55, the power supply wiring 56 and the wiring 57 need only be one wiring installation work, the installation cost can be reduced. it can.
In the present embodiment, the number of times the switch 51 is operated is counted by the control unit 110, and the shutter 200 is opened, closed, or stopped according to the count value. There is no need to separately provide a switch for opening, closing, and stopping the shutter 200, and the number of switches can be reduced.
