Description

  The present invention relates to a control device for an electric blind.

  2. Description of the Related Art Conventionally, a control device has been put into practical use that can collectively control the raising and lowering operations of electric blinds arranged on a plurality of floors of a building. In such an electric blind control device, all blinds can be collectively controlled based on a command from the central control device.

Each blind is controlled by an operation switch provided for each electric blind or an operation switch provided for each specific group including a plurality of electric blinds.
FIG. 6 shows an example of a conventional electric blind control device. The floor units 1a to 1d are installed on each floor of the building, and are connected to a large number of blinds installed on the same floor. Further, each floor unit 1a to 1d is connected to a personal computer 2, and a command signal output from the personal computer (automatic control device) 2 is output to the corresponding blind via each floor unit 1a to 1d, and based on the command signal. Thus, the operation of each blind is controlled.

  For example, seven blinds 3a to 3g are connected to the floor unit 1a, and a first operation switch 4a that enables the blinds 3a to 3g to be collectively operated, and blinds 3e to 3g installed in a conference room or the like, for example. Is connected to a second operation switch 4b that can only be operated.

  In such a control device, when an auto mode signal is input from the personal computer 2 to the blinds 3a to 3g via the floor unit 1a, the blinds 3a to 3g are connected to the first and second operation switches 4a and 4b. The command signal is not accepted. Therefore, the blinds 3a to 3g can be controlled only based on the command signal from the personal computer 2.

  On the other hand, when a local mode signal is input from the personal computer 2 to each of the blinds 3a to 3g via the floor unit 1a, each of the blinds 3a to 3g does not accept a command signal from the personal computer 2. Therefore, each blind 3a-3d can be controlled only based on a command signal from the first operation switch 4a, and each blind 3e-3g can be controlled by operating the first operation switch 4a or the second operation switch 4b. It becomes.

  When a common mode signal is input from the personal computer 2 to the blinds 3a to 3g via the floor unit 1a, the blinds 3a to 3g receive command signals from the personal computer 2 or the first and second operation switches 4a and 4b. Either can be controlled.

  In FIG. 7, the signal converter 5 is interposed in the wiring between the blinds 3d and 3e. The signal converter 5 has a function of selecting whether or not the command signal of the first operation switch 4a is supplied to the blinds 3e to 3g, and can be selected by operating the changeover switch.

And if the signal converter 5 is made into an OFF state, the command signal of the 1st operation switch 4a or the personal computer 2 will not be supplied to the blinds 3e-3g.
Therefore, if the signal converter 5 is turned on, the operations of the blinds 3a to 3g by the first operation switch 4a, the operations of the blinds 3a to 3g by the personal computer 2, and the blinds 3e to 3g by the second operation switch 4b are performed. Can be operated. If the signal converter 5 is turned off, the blinds 3e to 3g can be operated only by the second operation switch 4b.

  In FIG. 8, blinds 3h to 3j and a signal converter 6 are further added, and a third operation switch 4c for operating the blinds 3h to 3j is provided. If the signal converter 6 is turned off, the command signal of the third operation switch 4c is not supplied to the blinds 3e to 3g.

Patent Document 1 discloses a configuration similar to the control device for an electric blind as described above.
JP 2004-285604 A

  In the control device shown in FIG. 6, when the auto mode is set, the blinds 3e to 3g installed in the conference room cannot be operated by the second operation switch 4b, and based on a command signal from the personal computer 2 Can only be controlled.

  Further, when the local mode is set, the blinds 3e to 3g can be operated by any of the first and second operation switches 4a and 4b. In the shared mode, the personal computer 2 and the first and second operation switches 4a and 4b can be operated.

  Therefore, in any of the auto mode, the local mode, and the shared mode, it is not possible to select a state in which the blinds 3e to 3g can be controlled only by the second operation switch 4b in the conference room. 3e-3g may be inadvertently operated from outside the conference room.

  In the control device shown in FIGS. 7 and 8, when the signal converters 5 and 6 are turned off, the blinds 3e to 3g can be operated only by the second operation switch 4b. However, since the signal converter 5 is usually installed in the ceiling or in the curtain box, the switching operation is complicated.

  An object of the present invention is to provide a control device for an electric blind that allows a specific group of blinds to be operated only by a corresponding specific operation switch while allowing the auto mode, the local mode, and the common mode to be set.

  According to a third aspect of the present invention, the sub switch includes a changeover switch that forcibly switches between the local mode and the shared mode as the local mode setting means.

  ADVANTAGE OF THE INVENTION According to this invention, the control apparatus of the electric blind which enables operation of only the specific operation switch corresponding to the blind of a specific group can be provided, making it possible to set an auto mode, a local mode, and a common mode.

(First embodiment)
Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The same components as those in the conventional example will be described with the same reference numerals.

  The electric blind control device shown in FIG. 1 has a tilt unit 11 interposed between the conventional blinds 3d and 3e shown in FIG. 5, and the tilt unit 11 is used to operate the blinds 3e to 3g as subgroups. Three operation switches (sub-switches) 12 are connected. The first operation switch (main switch) 4a for operating the blinds 3a to 3g serving as the main group is the same as the conventional example.

The third operation switch 12 is provided with a changeover switch 13 for switching between the shared mode and the local mode.
The configuration of the tilt unit 11 will be described with reference to FIG. A command signal input from the personal computer 2 via the floor unit 1 a is input to the microcomputer 16 via the first command signal input / output unit 14.

The command signal input from the third operation switch 12 is input to the microcomputer 16 via the second command signal input / output unit 15.
The microcomputer 16 is connected to first and second setting switches 17a and 17b for setting a blind range controlled by the tilt unit 11. The minimum value of the blind number to be controlled can be set in the first setting switch 17a, and the maximum value of the blind number to be controlled can be set in the second setting switch 17b. In this embodiment, the number of the blind 3e is set to the first setting switch 17a, the number of the blind 3g is set to the second setting switch 17b, and the blinds 3e to 3g are controlled by the tilt unit 11. It has become.

An EEPROM 18 is connected to the microcomputer 16. The EEPROM 18 stores a program for controlling the microcomputer.
Next, the operation of the tilt unit 11 will be described with reference to FIGS. Based on the start of the operation, the tilt unit 11 waits for a command signal from the personal computer 2 or the third operation switch 12 (steps 1 and 2).

  In this state, a switching signal for switching between the shared mode and the local mode is input from the third operation switch 12. If the switching signal is a local command signal for setting the local mode (steps 3 and 4), the process proceeds to step 5 to convert the local command signal into an auto command signal. It outputs to each blind 3e-3g (steps 5 and 6).

  When the operation command signal of at least one of the blinds 3e to 3g is input from the third operation switch 12 (steps 7 and 8), the tilt unit 11 uses the operation command signal as the slat raising / lowering operation, the angle adjustment operation or the like. Is transmitted to the corresponding blind among the blinds 3e to 3g (step 9). Then, the process returns to step 1.

  By such an operation, the blinds 3e to 3g are in a state of not accepting a command signal from the first operation switch 4a, and are in a state of operating only based on the operation command signal from the third operation switch 12.

  In step 7, when the operation command signal is not input from the third operation switch 12 within the predetermined time, the process returns to step 1. If a switching signal for switching between the shared mode and the local mode is input from the third operation switch 12 in step 8, the process returns to step 4.

  In step 4, when a shared command signal for setting the shared mode is input, the tilt unit 11 outputs a forced command signal to the blinds 3e to 3g to set the blinds 3e to 3g to the shared mode (step 10). Return to step 1. In this state, the blinds 3e to 3g can be operated from any of the first and third operation switches 4a and 12.

  In step 3, when a normal operation command signal is input from the third operation switch 12, when the common mode is set, the tilt unit 11 uses the operation command signal as a slat raising / lowering operation and an angle adjustment operation. Or it transmits to the corresponding blind among the blinds 3e-3g as a normal command signal for performing those stop operation (steps 11 and 12). Then, the process returns to step 1.

  When the local mode is already set, the operation command signal is used as a forced command signal for performing the slat raising / lowering operation, the angle adjustment operation, or the stop operation thereof, and the corresponding blind among the blinds 3e to 3g. (Steps 11 and 13) and return to step 1.

  In step 1, when an auto command signal is input from the personal computer 2, the tilt unit 11 cancels the forced mode by the changeover switch 13 and sets the normal mode (step 14), the third operation switch 12 and the blinds 3e to 3e. A command signal for setting the auto mode is output to 3g (steps 15 and 16).

  In this state, when the common mode is set by operating the third operation switch 12 (steps 17 and 18), the tilt unit 11 outputs a command signal for setting the common mode to the blinds 3e to 3g (step 19). Return to step 1. In this state, the blinds 3e to 3g can be operated by any of the personal computer 2 and the first and third operation switches 4a and 12. If it is determined in step 18 that the command signal is not for setting the shared mode, the process returns to step 17.

  In step 17, when the third operation switch 12 is not operated, the blinds 3e to 3g are in a state of accepting only the command signal from the personal computer 2, and based on the command signal inputted from the personal computer 2, The raising / lowering operation, the angle adjusting operation or the stopping operation thereof is performed (step 20).

  The outline of the function of the tilt unit 11 as described above is as shown in FIG. When a local command signal is received from the third operation switch 12 (step 21), the local command signal is converted into an auto command signal (step 22) and output to the target blinds 3e to 3g (step 23). In this state, the blinds 3e to 3g do not accept the command signal from the first operation switch 4a.

  Next, when a command signal for operating the blinds 3e to 3g is input from the third operation switch 12 (step 24), the command signal is converted into a forced command signal (step 25) and output to the corresponding blind. (Step 26). Accordingly, the blinds 3e to 3g can be operated by operating the third operation switch 12.

  Next, when a shared command signal is input from the third operation switch 12 (step 27), the shared command signal is converted into a forced command signal (step 28) and output to the target blinds 3e to 3g (step 28). 29). In this state, the blinds 3e to 3g receive command signals from the personal computer 2 and the first and third operation switches 4a and 12.
