[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric opening / closing device such as an electric blind or an electric roll screen which is installed in an opening / closing portion of a house for the purpose of shading or blindfolding, and more particularly to control of an electric opening / closing device of different models. The present invention relates to an electric switchgear having improved assemblability without deteriorating efficiency.

[0002]

2. Description of the Related Art At present, a plurality of electric switchgears are provided, and they are controlled for lighting.
There are commercially available motorized opening and closing systems that can be centrally controlled to save on heating and cooling costs and maintain aesthetics throughout the building.
In a building in which this system is adopted, an electric switchgear suitable for environmental conditions such as internal aesthetics, functions, and space is required for each room or each floor.

[0003] As typical electric switchgears currently on the market, there are those using a horizontal blind, a vertical blind, a roll screen and the like. Each of these electric opening / closing devices basically has a DC motor or an induction motor, and the rotation of the motor causes the opening and closing and lifting / lowering of a plurality of blades as a function of a horizontal blind, and a plurality of blades as a function of a vertical blind. As the functions of the rotation / opening / closing of the blades and the roll screen, lifting and lowering of the roll-shaped fabric are realized, and lighting and shading of the room are adjusted.

[0004] Each electric switching device has a control unit for realizing the respective functions and a driving unit controlled by the control unit to drive the motor. The functions realized by each electric switching device are as follows. Since each model is different, a dedicated control unit and drive unit are required for each model. Therefore, when these control units and drive units are manufactured, a board assembly including dedicated control functions and drive functions is manufactured, and development time and development costs are generated for each type of electric switchgear. Will do.

On the other hand, in the case of a total system recently found in an intelligent building or the like, if it is desired to control each electric switching device, communication control using an interface and a signal system suitable for each electric switching device must be performed. No. Therefore, on the building management computer side, a dedicated control program, a dedicated interface, and a communication line are required for each type of electric switchgear having different functions to be realized, and time and cost for construction are required.

[0006] Although the electric switchgear is different in type, such as a horizontal blind, a vertical blind, and a roll screen, these are commonly configured to include a drive unit of a motor and a control unit for controlling the drive unit. You.

The electric opening and closing device disclosed in Japanese Patent Application Laid-Open No. Hei 6-137048 is provided with a plurality of electric blinds and a controller connected to each blind by a communication line to centrally control the plurality of blinds, and receives a command signal from the controller. It enables the control of the vertical movement of each blind and the setting of the reference height.

In the electric screen interlock device disclosed in Japanese Patent Application Laid-Open No. 5-86785, when an ascending / descending command is issued from a plurality of operation panels through signal lines, the elevating / lowering of the roll screen is performed based on a desired command signal. Is configured to be controlled.

The above-mentioned conventional electric switchgears are all one or more electric switchgears, a controller (operation panel) for issuing an operation command to these electric switchgears, and a communication connection between the controller and the electric switchgear. Each electric switching device is further provided with a motor control device (drive unit) for controlling the motor, an MPU (control unit) for controlling the motor control device, and an interface circuit (communication interface unit) between the MPU and the controller. ). When the electric circuits forming the blinds are classified by blocks, there are many functionally equivalent circuits to those of the roll screen. Therefore, each circuit can be shared for each block between the two.

However, the control method differs between the blind and the roll screen due to the difference in mechanical structure. Further, since the members used for opening and closing are different between the blind and the roll screen, the specifications of the motor for opening and closing are also different.

As described above, even if the respective electric switchgears can be shared at a rough structure or at a functional block level, the control method differs for each model or the motor specifications differ. It was extremely difficult to do.

It is therefore an object of the present invention to provide an electric switchgear which can be efficiently assembled even when the models are different.

Further, the MPU 7 has an input unit 7c for inputting data including various instruction signals relating to the opening / closing operation by being externally operated.
An output unit 7a for externally outputting various messages in operations such as error notification is connected.

The memory 10 stores a control program 10a or 10b downloaded by the communication control program 7b. Since the number of control programs that can be downloaded is proportional to the capacity of the memory 10,
The number of control programs stored in 0 matches the expected number of models of the electric switchgear (the number of drive units requiring a specific control program). In the example of FIG. 2, the number of control programs is two.

FIG. 3B shows a connection between the control unit 8 and the driving unit 17, and FIG. 3C shows a connection between the control unit 8 and the driving unit 18.
Are shown in detail. FIG.
In each connection section (c), the identification setting interface 11 of the control section 8 has input terminals IN1, IN2, and IN3 and performs 3-bit parallel input.

Also, corresponding to each of the terminals IN1, IN2 and IN3, each of the identification setting sections 13 to 16 of the corresponding driving sections 12, 17 and 18 has output terminals OUT1, OUT2 and OUT3. Performs 3-bit parallel output.

Further, as shown in the figure, the control section 8 and each drive section include an identification section corresponding to the identification setting interface 11 and a control section side common terminal 28 and a drive section side common terminal 29, respectively.
By connecting the signals collectively for each signal, the connection unit is shared by using a connector or the like, and the control unit 8 and each drive unit have a detachable connection structure.

3A to 3C, a motor control signal between the control unit and the driving unit, a corresponding encoder signal for detecting the height position of the blind or the roll screen,
Various signals such as an upper limit SW (abbreviation of a switch) signal, a failure SW signal, and a zero-cross signal 30 described later are input / output via a control unit side common terminal 28 and a drive unit side common terminal 29.

In an electric switchgear using an AC motor as a motor, the number of rotations of the motor varies depending on the power supply frequency (50/60 HZ), so that it is necessary to control the rotation of the motor at a constant speed. In this case, the power supply frequency is detected and the motor is turned on / off based on the detection result.
Control to rotate at a constant speed. As a method of detecting a power supply frequency, a method of detecting a zero cross signal 80 based on a zero cross point of an AC power signal is known.
Here, a zero-cross signal may be used to specify the control method of the drive unit. That is, in the horizontal blind 30, the setting contents of the identification setting unit 13 are the same as shown in FIG. 3A, but the drive unit 12 of the horizontal blind 30 using the AC motor as the motor 14 has the zero cross signal 80.
Since the drive unit 12 of the horizontal blind 30 using the DC motor does not need to detect the frequency of the AC power supply, the zero cross signal 80 is not provided, and the identification signal of the control method based on the difference of the motor based on the presence or absence of the zero cross signal 80 is provided. It can be.

In FIG. 1, the identification setting units 13, 15, and 1
The identification data set for each of No. 6 is data for identifying a drive unit for realizing an operation mode corresponding to the model of the electric switchgear. In detail, FIG.
Is a drive unit for realizing an operation mode corresponding to the horizontal blind 30 by setting the terminals OUT1, 2 and 3 of the identification setting unit 13 to levels 0 (ground level), 1 and 1, respectively. It is instructed.
Also, in FIG. 3B, similarly, the terminals OUT1, 2, and 3
Are set to levels 1, 0 and 1 to indicate that the drive unit is for realizing the operation mode corresponding to the vertical blind 31. And FIG.
In (c), similarly, by setting the terminals OUT1, OUT2, and OUT3 to levels 0, 1, and 1, respectively, it is instructed that the driving unit is for realizing the operation mode corresponding to the roll screen 31. You.

Since the signal level setting of the terminals described above is unique to the substrate of the driving unit in each operation mode (for vertical blind, horizontal blind, and roll screen), the pattern of the circuit board forming the driving unit is set. This setting may be performed at the time of design, or may be performed by a jumper.

FIG. 4 is a diagram showing the classification of signals transmitted and received by each electric switchgear via the signal line 5 of FIG. As shown in FIG.
Signal 50 that the controller 4 transmits to each of the electric switchgears (30 to 32), and conversely, each of the electric switchgears 30 to 32
And an up signal 60 to be transmitted.

The down signal 50 and the up signal 60
There are several types of signals. The down signal 50 includes an operation signal 51 for the computer 21 and the controller 4 to operate each electric switch, and a control unit 8 of each electric switch.
There is a program setting signal 52 for transmitting a control program. The program setting signal 52 includes a control program 54 and device setting information 53 for specifying which type of driving unit control program this control program 54 is.
including.

The control unit 8 of each electric switchgear refers to the device setting information 53 of the program setting signal 52, and the control program 54 corresponding to the driving unit connected to the control unit 8
Can be selected.

The rising signal 60 indicates that the transmitted control program 54 is not a control program matching the drive unit in the control unit 8 or that the control program of the drive unit does not exist in the memory 10 of the control unit 8. Computer 2
1 includes a reply signal 61 requesting transmission (download) of a necessary control program. When no control program is stored in the memory 10 of the control unit 8, there is a notification signal 62 for requesting the computer 21 to transmit (download) a necessary control program.

FIG. 5 and FIG. 6 are processing flowcharts of the respective electric switching devices shown in FIG. 5 and 6
The operation of the electric switching device when the power of the MPU 7 is turned on will be described with reference to FIG. When the power is turned on (step a0 in FIG. 5), the MPU 7 reads the contents of the memory 10. MP
U7 first checks whether a control program is stored in the memory 10 (step a1). When the power is turned on for the first time (when power is turned on after assembly or during construction), the control program is in a state where the memory 12 is not stored at all.

If the control program is not stored (NO in step a1), the MPU 7 issues an unset notification to the effect that the control program is not stored externally via the output unit 7a. It notifies the outside (operator or constructor) that it does not operate and that the control program is not stored (step b1).

Subsequently, the MPU 7 operates the communication control program 7b to transmit the notification signal 62 on the signal line 5 via the communication interface 6 (step b2).
Usually, a data setting computer 21 is connected to the signal line 5 at the time of assembly or construction. Notification signal 62
Is received by the data setting computer 21. Upon receiving the notification signal 62, the data setting computer 21 outputs the program setting signal 52 to the signal line 5.

After transmitting the notification signal 62, the control unit 8 of the electric switchgear stands by to receive the program setting signal 52 (step b3). At this time, the electric switchgear is in a stopped state and is on standby (step b4). Therefore, it is possible to prevent the electric switchgear from operating in a state in which the corresponding control program is not set, and damage the device.

When the MPU 7 receives the program setting signal 52 while waiting for the reception of the program setting signal 52, the MPU 7 extracts the device setting information 53 included in the program setting signal 52. The device setting information 53 may be “110” if the program setting signal 52 is for a horizontal blind control program 541, for example, or may be for a vertical blind control program 542, as shown in FIG. "101", roll screen control program 54
For example, it is set as "011" for the third.

The MPU 7 reads the identification data described with reference to FIG. 3, and reads the identification data and the received device setting information 53.
Are compared (step b5), and if they match, the control program 54 included in the received program setting signal 52 is written and stored in the memory 10 (step b6). That is, the MPU 7 inputs the identification data given to the input terminals IN1 to IN3 of the identification setting interface 11, and
Compare with device setting information.

For example, the received program setting information 5
If the device setting information 53 of No. 2 is “110”, the type of the control program 54 included in the program setting signal 52 is the “horizontal blind control program 541”. When such a program setting signal 52 is transmitted from the data setting computer 21 and received by the control unit 8, the MPU 7 reads the identification data next. Here, when “110” shown in FIG. 3 is input as the identification data, the driving unit 1 for the horizontal blind 30
2 is determined to be connected. Device setting information 53
(“110”) and the signal of the identification data (“110”) match, so the MPU 7 stores the received control program (horizontal blind control program 541) in the memory 1
0 is stored as the control program 10a or 10b.

If the identification data is other than "110", it does not match "110" of the received device setting information 53, so the MPU 7 judges that the received program setting information 52 is an invalid signal, and outputs it to the output unit. An external notification is made from 7a (step b1), a notification signal 62 is transmitted (step b), and the reception of the program setting signal 52 is waited again (step b3).

On the other hand, if the control program is stored in the memory 10 (YES in step a1),
A comparison is made between the control unit side information corresponding to each control program in 0 and the identification data (step a2).

As described above, the memory 10 can store a plurality of control programs depending on the size of the storage area.
When the same control unit 8 is set in a drive unit of an electric switchgear of a different model, the MPU 7 stores a control program corresponding to each different model in the memory 10.

The control program is provided in advance with control section information for distinguishing which type of drive section the control program is for. For example, the control unit side information "11
“0” indicates a control program for a horizontal blind, “101” indicates a control program for a vertical blind, and “011” indicates a control program for a roll screen. The information can be set using the device setting information 53 included in the program setting signal 52.

As shown in FIG. 2, the control programs 10a and 10a
b is stored in the memory 10, the MPU 7 sequentially controls the control unit side information 10 corresponding to the control programs 10a and 10b.
a1 and 10b1 are sequentially compared with the identification data shown in FIG. If they match, the MPU 7 determines that the control program corresponding to the matched control unit information is executable, and executes this program. As a result, control specific to the drive unit connected to the control unit 8 is performed.

At this time, the operation mode is executed based on a signal indicating the contents of the opening / closing operation given to the MPU 7 through the input unit 7c, the operation button 2 of the controller 4, or the computer 21. The opening / closing operation of the contents to be performed is realized in the corresponding opening / closing section.

For example, in the memory 10, the control program 10a is a horizontal blind control program, the control unit side information 10a1 is "110", and the control program 10b is a vertical blind control program, and the control unit side information 10b.
When 1 is stored as "101", the MPU 7 next reads the identification data. Here, when “110” is input as the identification data, the horizontal blind 30
Is determined to be connected, the device setting information 10a1 of the control program 10a is determined.
("110") matches the identification data ("110"), so that the MPU 7 recognizes the control program 10a as a program to be executed, and transfers control to the execution program (step a3).

Here, when "011" is input as the identification data, it is determined that the driving unit 18 for the roll screen 32 is connected. The device setting information 10a1 (“110”) of the control program 10a is compared with the identification data (“011”). However, since the two do not match, the device setting information 10b1 of the next control program 10a is compared.
(“101”) and the identification data (“011”) are compared. Here again, since they do not match, it is necessary to download a new control program (N in step a2).
O).

If the control program stored in the memory 10 does not exist as a control program of the connected drive unit, the control unit 8 controls the drive unit connected to the outside via the output unit 7a. An unset notification that the program is not stored is issued, and the fact that the electric switch is not operating and that the corresponding control program is not stored in the connected drive unit is notified externally (operator or installer). (Step c1).

Subsequently, the MPU 7 executes the communication control program 7
By operating b, a notification signal 62 is transmitted to the signal line 5 via the communication interface 6 (step c2). Usually, a data setting computer 21 is connected to the signal line 5 at the time of assembly or construction. This notification signal 6
2 is received by the data setting computer 21. When receiving the holding signal 62, the data setting computer 21 operates to output the program setting signal 52.

The control unit 8 of the electric switchgear that has transmitted the notification signal 62 is on standby to receive the program setting signal 52 (step c3). At this time, the electric switchgear is in a stopped state and is on standby (step c4). Therefore, it is possible to avoid a situation in which the apparatus is operated without setting the control program corresponding to the model and the apparatus is damaged.

When receiving the program setting signal 52 in the standby state at step c3, the MPU 7 extracts the device setting information 53 included in the program setting signal 52.

The MPU 7 reads the identification data and compares the identification data with the received device setting information 53 (step c5). If the two match, the control program 54 included in the received program setting signal 52 is read. It is stored in the memory 10 (step c6). That is, MPU7
Are input terminals IN1 to IN1 of the identification setting interface 11.
The identification data given to N3 is input and compared with the received device setting information 53.

For example, the received program setting signal 5
2 and the device setting information 53 are “110”, the control program 54 included in the program setting signal 52 is a “horizontal blind control program”. Such a signal is transmitted from the data setting computer 21,
If received by the control unit 8, the MPU 7 next takes in the identification data. Here, when “110” is obtained as the identification data, the driving unit 12 for the horizontal blind 30
Is determined to be connected. Therefore, the received device setting information 53 (“110”) matches the input identification data (“110”), so that the MPU 7 stores the received control program 541 in the memory 10.

If the identification data is other than "110", it does not match the device setting information 53 ("110") (NO in step c5), so the MPU 7 judges the received program setting signal 52 as an invalid signal, etc. This is reported to the outside from the output unit 7a (step c1), a notification signal 62 is transmitted (step c2), and the reception of the program setting signal 52 is again waited (step c3).

Since the control program stored in the memory 10 in this way is a control program corresponding to the connected drive unit, the MPU 7 recognizes the control program stored in the memory 10 as a program to be executed. Then, control is transferred to the execution program (step a3).

As described above, the rewritable memory 10 is provided in the detachable control section 8, and the control program corresponding to the model connected thereto can be downloaded, stored and executed from the outside. It is possible to assemble efficiently and the construction becomes easy.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
