DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric blind control device for controlling a plurality of electric blinds collectively.

[0002]

2. Description of the Related Art In recent years, the control of electric blinds for controlling the operation of a large number of electric blinds installed on each floor of a building based on a preset program or an operation signal generated by manual operation of an operation device. The device has been put to practical use.

In such an electric blind, each electric blind is connected via a signal line, and the signal line has a central control device for automatically controlling the operation of all the blinds and a blind for each specific area or group. An area switch for controlling the operation by manual operation is connected.

When an operation signal is output from the central control device to each electric blind based on a program preset in the central control device, each electric blind is built in the head box based on the operation signal. The blind controller operates to automatically perform the slat elevating operation and the angle adjusting operation.

When the area switch is operated, a preset area number and an operation signal are output from the area switch to each of the electric blinds, and each of the electric blinds has an area number and a preset number set in the blind controller. When the input area number matches the input area number, the slat lifting / lowering operation and the angle adjustment operation are performed based on the operation signal.

As a manual operation means other than the area switch, there is an electric blind in which a remote control transmitter is set. In such an electric blind, for example, the area switch receives the remote control signal output from the remote control transmitter. Has functions.

[0007] When a remote control signal for controlling each electric blind in the area is output to a specific area switch by operating the remote control transmitter, the area switch that has received the remote control signal receives the remote control signal based on the remote control signal. To control the operation of the electric blind in the area.

Each of the electric blinds is provided with a blind controller in a head box, and the blind controller drives a slat elevating motor or a slat angle adjusting motor based on the operation signal to raise and lower the slat. Alternatively, a slat angle adjustment operation is performed.

[0009]

In the electric blind as described above, a unique area number is preset in each area switch, and the blind controller of each electric blind has an area number corresponding to the area to which the electric blind belongs. Is set in advance.

When an arbitrary area switch is operated, the operation of the electric blind in which an area number equal to the area number output from the area switch is set is controlled.

[0011] Then, when changing the area composition in accordance with the layout change of the electric blind, it is necessary to change the area switch or the area number set in each electric blind.

Since an area switch is set with an area number using a dip switch or the like, in order to change the area number, an operator must go to a location where the area switch is installed and change the setting of the dip switch. Therefore, the operation is complicated.

In the blind controller of each electric blind, when the area number is set by the DIP switch, the operator goes to the installation location of each electric blind and sets the DIP switch, as in the case of the area switch. Must be changed, and the operation is complicated.

Further, in the blind controller in which the area number of each electric blind can be written from the central control device, the work of updating the area number set in the blind controller is required in accordance with the change of the area composition, and the update is required. When the number of electric blinds increases, the updating work becomes complicated.

On the other hand, although the central control device can grasp the operation state of each electric blind, when each electric blind is operated by the area switch, it is grasped whether or not an operation signal is transmitted from the area switch. I can't.

Therefore, if an operation signal is transmitted from the area switch to the electric blind immediately after transmitting an operation signal from the central control device to one of the electric blinds, the electric blind is based on the operation signal of the area switch. Therefore, the operator who operates the central control device may mistakenly think that the system is out of order.

An object of the present invention is to provide a control device for an electric blind in which the operation of each electric blind by an area switch can be grasped by a central control device. Another object of the present invention is to provide a control device for an electric blind in which an operation of each electric blind by an area switch can be grasped by a central control device and an area composition can be easily changed.

[0018]

According to the present invention, a large number of electric blinds can be collectively controlled by a central controller, and the electric blinds in a specific area set in advance based on the operation of an area switch are collectively controlled. In the control device of the electric blind which can be controlled, the central control device receives an operation signal output to each electric blind from the area switch, and can store operation contents of each electric blind by the area switch. .

According to a second aspect of the present invention, the central controller comprises a floor controller for controlling the operation of each of the electric blinds, and a main controller for controlling the operation of the floor controller. The main controller can grasp the information via the floor controller.

According to a third aspect, the area switch includes:
An identification number for identifying the area switch can be set, and the main controller can output an area setting signal for associating the identification number with the area number to the area switch.

FIG. 4 shows the electrical configuration of the area switch 5.
It will be described according to. An input / output unit 28 is connected to the CPU 27, and the input / output unit 28 is connected to the blind controller 4.

An operation unit 29 is connected to the CPU 27. Based on the operation of the operation unit 29, the CPU 27 generates an operation signal for raising or lowering or adjusting the angle of the slat of each electric blind in the area, and performs input / output. Output to the unit 28.

The setting switch unit 30 connected to the CPU 27 is constituted by a dip switch. The setting switch unit 30 is set with a unique identification number which does not overlap with the other area switches 5. Can be read.

An EEPROM 31 is connected to the CPU 27 so that the area number of the area switch 5 can be stored. A ROM 32 is connected to the CPU 27, and the ROM 32 stores various data necessary for generating an operation signal based on an operation of the operation unit 29.

Next, the initial setting operation for area composition in the electric blind control device configured as described above will be described. First, a common classification number is set in the setting switch section 13 of the blind controller 4 belonging to the common area, and the setting switch section 30 of the area switch 5 is set.
Is set to an identification number that enables each area switch 5 to be specified.

In this state, when the main controller 1 starts the initial setting operation, as shown in FIG. 5, the CPU of the main controller 1 inputs the area setting information based on the input of the area setting information (step 1). Is stored (step 2), and the area setting information is output to each floor controller 3 as an area setting command (step 3).

Then, the main controller 1 waits for the setting confirmation information from the floor controller 3 (step 4). The area setting information input to the main controller 1 includes a target floor controller number,
The information includes information for associating the classification number set in each blind controller 4 with the area number, information for associating the identification number set in each area switch 5 with the area number, and the like.

When the area setting information is output from the main controller 1 to the floor controller 3, as shown in FIG. 6, the CPU 22 of the floor controller 3 determines whether or not a command from the main controller 1 has been received. It is determined whether or not the command includes its own floor controller number (step 11).

If the input command is directed to itself, it is determined whether or not the command is an area setting command (step 12). If the command is not an area setting command, Then, the CPU 22 performs an operation based on the input command (step 13), and returns to step 11.

When an area setting command is input in step 12, the CPU 22 stores the input area setting information in the EEPROM 25 (step 14), and stores the area setting information in the area switch 5 via the blind controller 4 in the area switch 5. It is output as a setting command (step 15). This area setting instruction includes information for associating the identification number of the area switch 5 with the area number.

Then, the CPU 22 enters a state of waiting for the setting confirmation information from the area switch 5 (step 16).
As shown in FIG. 7, when a command is input from the floor controller 3 to the area switch 5 via the blind controller 4 (step 21), the CP of the area switch 5 is
U27 determines whether the command is an area setting command (step 22). If the instruction is not an area setting instruction, the CPU 27 performs an operation based on the input instruction (step 23), and returns to step 21.

In the blind controller 4, the area number corresponding to the classification number is stored in the EEPROM 12. When an area setting command is input in step 22, the CPU 27 rewrites the area setting data based on the input area setting command (step 24), and uses the rewritten setting data as setting confirmation information via the blind controller 4 via the floor controller 4. Output to the controller 3 (step 25).

When the setting confirmation information is input to the CPU 22 of the floor controller 3 in step 16 shown in FIG.
Then, it is determined whether or not the area setting command stored in step 5 matches the area setting command (step 17).

If they do not match, step 15
And the area setting command is output again. If the setting confirmation information matches the area setting instruction in step 17, the CPU 22 outputs the setting confirmation information to the main controller 1 (step 18), and returns to step 11.

In step 4 shown in FIG. 5, when setting confirmation information is input from the floor controller 3 to the main controller 1, the main controller 1 checks whether the setting confirmation information matches the area setting instruction output in step 3. It is determined whether or not it is (step 5).

If they do not match, the process returns to step 3 and outputs the area setting command to the floor controller 3 again. If the setting confirmation information matches the area setting instruction in step 5, the main controller 1
Ends the initial setting operation for area composition.

Next, the operation of the collective control operation based on the operation of the area switch 5 will be described. As shown in FIG. 8, when the area switch 5 is operated and an operation signal is input, the CPU 27 of the area switch 5 outputs the operation signal to the blind controller 4 (step 32), and returns to step 31. It is in a state of waiting for the input of the next operation signal.

The operation signal output from the area switch 5 to the blind controller 4 includes a setting signal for setting the operation contents of each blind, an area number, and an identification number of the area switch 5.

As shown in FIG. 9, when an operation signal is input to the blind controller 4 (step 33), C is set.
The PU 10 outputs the operation signal to the floor controller 3 (Step 34), and then determines whether or not the area number included in the input operation signal matches the area number stored in the EEPROM 12 (Step 3).
5).

If the area numbers do not match in step 35, the CPU 10 returns to step 33,
If they match, the process proceeds to step S36. Step 3
At 6, the CPU 10 compares the setting signal included in the input operation signal with the current blind opening and slat angle, and if they are the same, there is no need to drive the slat.

If the setting signal included in the input operation signal in step 36 does not match the current blind opening and slat angle, the CPU 10 drives the slat based on the operation signal (step 37). ,
It returns to step 33.

As shown in FIG. 10, when the floor controller 3 receives an operation signal from the blind controller 4 (step 38), the CPU 22 transmits operation signal information obtained by adding a date and time to the input operation signal to the EEPR.
It is stored in the OM 25 (step 39).

Next, the CPU 22 outputs to the main controller 1 operation signal information obtained by adding the date, time and the number of the floor controller 3 to the input operation signal (step 40), and returns to step 38.

As shown in FIG. 11, when the operation signal information is input from the floor controller 3, the main controller 1 repeats the operation of storing the operation signal information in the memory (steps 41 and 42).

Therefore, the main controller 1 can recognize the operation contents and the operation time of the blind in each area by the area switch 5. Further, the main controller 1 has a function of periodically checking the operation state of the area switch 5 via the floor controller 3 and the blind controller 4.

The operation of the main controller 1 during the checking operation will be described with reference to FIG. Based on the start of the confirmation operation, the main controller 1 first outputs a confirmation request signal for confirming the connection state of an arbitrary area switch 5 to the floor controller 3, for example, once every two minutes (step 51). The confirmation request signal is input to the area switch 5 via the floor controller 3 and the blind controller 4.

Next, the main controller 1 determines whether or not an acknowledgment signal has been received from the floor controller 3 based on the acknowledgment request signal (step 52). Is updated (step 53). The acknowledgment signal includes a signal indicating whether or not the connection state of the target area switch 5 is normal.

Next, when a signal requesting display of the connection state of the area switch 5 is input to the main controller 1 (step 54), the main controller 1 searches the database and searches for an area switch having a desired identification number or area number. 5 is displayed on the display device (step 5).
5, 56), and returns to step 51.

If no display request signal has been received in step 54, the process returns to step 51.
The main controller 1 can determine whether the area switch 5 is functioning normally or whether the connection of the area switch 5 is normal based on the confirmation response signal.

FIG. 13 shows the operation of the CPU 27 of the area switch 54 in accordance with the above-described confirmation operation. CPU
27 reads the set own identification number or area number as a switch number (step 57);
The number is stored in the EEPROM 31 (step 5).
8).

Next, upon receiving a confirmation request signal from the main controller 1 (step 59), the CPU 27 reads the switch number (step 60) and outputs it to the floor controller 3 as a confirmation response signal (step 6).
1) Return to step 57.

If no confirmation request signal is received in step 59, steps 57 to 59 are repeated. With the electric blind control device configured as described above, the following operational effects can be obtained.

(1) The slat elevating operation and the slat opening / closing operation of a large number of electric blinds can be automatically controlled based on a program set in the main controller 1.

(2) Based on the area setting information output from the main controller 1 to each of the blind controllers 4, the area number is associated with the classification number set for each of the blind controllers 4, and The identification number of each area switch 5 and the area number are associated based on the area setting information output to the switch 5. Therefore, the setting of the blind group controlled collectively by the common area switch 5 and the setting and change of the area switch 5 controlling the blind group can be easily performed.

(3) The contents of operating each electric blind in the area by the area switch 5 are stored in the main controller 1.
Can be grasped. (4) Even if the electric blind operates based on the operation of the area switch 5 immediately after outputting the operation signal from the main controller 1 and the operation signal of the main controller 1 becomes invalid, the area switch 5 is not Since the operation content is known, it can be easily recognized that the operation is normal.

(5) Since the main controller 1 periodically outputs a confirmation request signal to the area switch 5 and receives a confirmation response signal from the area switch 5,
Whether or not the connection state of the area switch 5 is normal can be periodically detected.

The above embodiment can be modified as follows. The transmission and reception of signals between the main controller 1 and the floor controller 3 or the transmission and reception of signals between the floor controller 3 and the blind controller 4 may be performed wirelessly without passing through the signal line 2. -The electric blind may be a horizontal blind, a lift curtain, a pleated curtain, or a roll blind. The area switch 5 has a function of collectively controlling the electric blinds in a specific area, and can individually control the electric blinds in the area.
Then, the content of individual operation by the area switch 5 may be grasped.
