  2. Description of the Related Art Conventionally, there is an electric blind control system that automatically controls a shielding amount adjustment operation of a plurality of electric blinds via a relay device by a management device that can be configured by a personal computer, for example.

  As an electric blind, for example, an electric horizontal blind having a plurality of slats, the shielding amount adjusting operation and tilting operation can be controlled by automatic control from a management device.

  Such a conventional electric blind control system operates so that the speed at the time of opening and closing of the electric blind is constant by an individual switch that can individually operate the electric blind and automatic control from the management device.

  For this reason, even if the shielding amount adjustment speed is appropriate for the operation of the individual switch, for example, during automatic control with daylight use, the shielding amount adjustment speed is fast.

  The state management means 111 holds the tilt amount and the lift position of all the blinds included in the electric blind control system of this embodiment in the storage unit 13 as state information, and the tilt amount of the slat 33 of each blind. Each time the elevation position changes, the status information is acquired via the communication unit 15 via the corresponding relay device 2 (in the example shown in FIG. 1, the relay device 2-1 or 2-2), and is stored in the storage unit 13. It has a function of updating the held state information. The state management unit 111 has a function of confirming the state information held in the storage unit 13 before the control command generation / transmission unit 113 generates the control command.

  The control mode setting means 112 sets the designated control mode input by the administrator of the electric blind control system of this embodiment from a predetermined operation unit (not shown) via the user IF control unit 12 in the morning for each blind. A control mode is set in a predetermined control section (that is, a use environment) so that different control is possible depending on the use time band divided into day and night, and the control mode is stored in the storage unit 13.

  As shown in FIG. 5, the storage unit 13 includes a management device state management table in which addresses of relay devices, addresses of blinds connected to the relay devices, state information of the blinds, and control modes are associated with each other. Is preferably maintained. Then, the function of the control unit 11 causes a setting screen to be displayed on a predetermined display unit (not shown) via the display control unit 14, and the administrator assigns the address of the relay device, the address of each blind, and the control mode. It can be configured to be input and set via a user IF control unit 12 from a predetermined operation unit (not shown).

It can be configured to have a function of generating by changing the number of control commands to be transmitted according to the type of tilt speed. For example, in a tilt operation at a fast tilt speed, a control command for one time is generated and transmitted. In a tilt operation at a slow tilt speed, the angle difference is large from the tilt amount based on the current state information. In this case, it is possible to have a function of generating a control command for a plurality of times and transmitting it in a plurality of times so that the tilt operation is controlled at a stepwise tilt speed with a tilt amount of a plurality of small angles.

For example, an identifier is given to each relay device 2 or blind, and the control command is sent to the control command. It can also be configured to add an identifier of the relay device 2 or blind to be a control command target. In this case, each relay device 2 or blind determines whether or not it designates itself every time it receives the control command. If it designates itself, the relay device 2 or the blind performs an operation according to the control command. If it does not specify itself, it can be configured to ignore the control command.

  As described above, the management device 1 automatically generates, as control commands, control commands related to the tilting and lifting operations of the slats in each blind based on the control mode set according to the usage environment, and the communication unit 15.

Further, the control command relay control unit 212 operates the control command analysis unit 213 for the control command received from the management device 1 via the communication unit 23, analyzes the control command from the management device 1, and performs a plurality of types of control. It can be configured to have a function of being divided into commands and outputting to the blind 3-N via the communication unit 24.

  The control command analysis means 213 has a function of analyzing the control command for the control command received from the management apparatus 1 and dividing it into a plurality of types of control commands. For example, when the control command received from the management apparatus 1 is scheduled to be tilted at a plurality of tilt speeds, the type of the tilt speed is determined, and one tilt control command at a fast tilt speed is used. In the tilt operation with the slow tilt speed, the control is performed multiple times so that when the angle difference is large from the tilt amount based on the current state information, the tilt is controlled step by step with the small angle tilt amount. It has a function to generate commands.

  Further, for example, when the control command received from the management apparatus 1 is given by the tilt amount of the control command, the control command analysis unit 213 determines the tilt amount based on the current state information, the tilt amount of the control command, If the angle difference is less than a predetermined value, a control command for one time is generated by a tilt operation at a high speed (Fast) tilt speed, and if the angle difference is greater than or equal to the predetermined value, a low speed (Slow It is also possible to have a function of generating a control command for a plurality of times so that the control is performed stepwise with a tilt amount of a small angle for a plurality of times by a tilt operation at a tilt speed of

  As described above, the relay device 1 is configured to output the control command from the management device 1 to the blind 3-N as it is, or the control command from the management device 1 is analyzed and divided into a plurality of types of control commands. It can be set as the structure output toward the blind 3-N.

  Hereinafter, the control operation of each example in the electric blind control system of the present embodiment will be described in order.

Example 1
FIG. 7 is a block diagram showing the control operation of Example 1 in the electric blind control system of one embodiment according to the present invention. FIG. 8 is an operation explanatory view of the control operation of Example 1 in the electric blind control system of one embodiment according to the present invention.

  First, referring to FIG. 7, the management apparatus 1 automatically controls the slats in each blind based on a control mode in which the control command generation / transmission means 113 sets a variable tilt speed according to the use environment. A control command including a control parameter designating the tilt speed of 33 is generated and transmitted to the designated relay device 2-1 (step S11a).

  Subsequently, the relay device 2 outputs the control command received from the management device 1 to the designated blind 3-N by the control command relay control unit 212 (step S12).

  Subsequently, the blind 3-N executes a tilt operation at a tilt speed controlled by the control command by the control command execution unit 512 (step S14).

  In this tilt operation, the blind 3-N controls the stepping motor 9 with the control pattern corresponding to the tilt speed by the tilt speed variable control means 513 (step S15). For example, when high speed (Fast), middle speed (Middle) and low speed (Slow) control parameters are configured to be controllable by a control command, the slat 33 is rotated at a tilt speed based on the input control command. The stepping motor 9 is controlled via the drive unit 55 so as to be moved.

  Subsequently, the blind 3-N holds or updates the executed tilt amount of the slat 33 in the storage unit 53 as the state information by the state holding / updating means 514 (step S16), and manages it via the relay device 2-1. It transmits to the apparatus 1 (step S17, S18).

  On the other hand, when the individual switch 5 is operated with respect to the tilt operation and the raising / lowering operation (step S11b), the blind 3-N inputs the operation signal by the operation signal execution means 511, and the tilt operation corresponding to the operation signal is performed. And the elevator operation is performed (step S13).

  Note that when the operation signal includes the tilt speed control parameter, when the tilt operation or the lifting operation is executed by the individual switch 5 (step S13), the process proceeds to step S15, and this tilt operation is performed. At this time, the stepping motor 9 may be controlled with a control pattern corresponding to the tilt speed. Even after the operation based on the operation signal, the blind 3-N holds or updates the executed tilt amount of the slat 33 in the storage unit 53 as the state information by the state holding / updating means 514 (step S16). -1 is transmitted to the management apparatus 1 (steps S17 and S18). The blind 3-N gives priority to the execution operation by the operation signal when the operation signal is received during the execution operation by the control command.

  In the operation of the first embodiment, for example, an operation mode as shown in FIG. 8 can be realized. That is, the management device 1 sends a control command including a tilt speed control parameter (P) set according to the use environment to each of the designated blinds 3-N, 4- through the relay devices 2-1, 2-2. Send to M. The designated blinds 3-N and 4-M execute a tilt operation with a variable tilt speed in accordance with the control parameter (P).

For example, control parameter (P):
・ High speed (Fast): Fast rotation (time of operation from fully closed to reverse fully closed is t1)
・ Middle speed: Normal rotation (operation time from fully closed to reverse fully closed is t2 (> t1))
・ Low speed (Slow): Slow rotation (T3 (> t2) operating time from fully closed to reverse fully closed)
The control command can be variably set at two or more or stepless tilt speeds.

  At this time, the designated blinds 3-N and 4-M are controlled to perform a tilt operation according to the control parameter (P). As described above, the control parameter (P) is defined so that the tilt speed can be properly used according to the use environment, and is configured to be included in the control command to control the use of the electric blind according to the shielding amount adjustment operation. The discomfort of the person can be reduced. And it can also reduce a user's discomfort accompanying the shielding amount adjustment operation | movement of an electric blind also by comprising so that the said control parameter may be included in the operation signal by the separate switch 5. FIG.

(Example 2)
FIG. 9 is a block diagram showing a control operation of Example 2 in the electric blind control system of one embodiment according to the present invention. FIG. 10 is an operation explanatory view of the control operation of Example 2 in the electric blind control system of one embodiment according to the present invention.

  First, referring to FIG. 9, the management apparatus 1 checks the status information of each blind held in the storage unit 13 by the status management unit 111 before generating the control command by the control command generation / transmission unit 113 ( Step S21).

  Subsequently, in the management apparatus 1, the control command generation / transmission means 113 schedules a tilt operation at a plurality of tilt speeds as in the control parameter (P) described above based on the control mode set according to the use environment. The type of the tilt speed is determined (step S22), and in the tilt operation with the fast tilt speed (step S22: No), a control command for one time is generated and transmitted, and the low speed ( In the tilt operation at the tilt speed of (Slow) (step S22: Yes), when the angle difference is large from the tilt amount based on the current state information, the control is performed multiple times so as to perform stepwise control with the multiple small tilt amounts. A command is generated and transmitted in multiple times (step S23).

  Subsequently, the relay device 2 outputs one or more control commands received from the management device 1 to the designated blind 3-N by the control command relay control unit 212 (step S24).

  Subsequently, the blind 3-N executes a tilting operation at a tilt speed controlled by the control command for one time by the control command execution means 512, or is controlled by the control command for the plurality of times. The tilt operation is controlled at a stepwise tilt speed with the tilt amount of the angle (step S25).

  In this tilt operation, the blind 3-N controls the stepping motor 9 with the control pattern corresponding to the tilt speed by the tilt speed variable control means 513 (step S26).

  Subsequently, the blind 3-N holds or updates the executed tilt amount of the slat 33 in the storage unit 53 as the state information by the state holding / updating means 514 (step S27), and manages it via the relay device 2-1. Transmit to device 1.

  In the operation of the second embodiment, for example, an operation mode as shown in FIG. 10 can be realized. That is, the management device 1 sends a control command including a tilt speed control parameter (P) set according to the use environment to each of the designated blinds 3-N, 4- through the relay devices 2-1, 2-2. Send to M. The designated blinds 3-N and 4-M execute a tilt operation with a variable tilt speed in accordance with the control parameter (P).

For example, control parameter (P):
・ High speed (Fast): Fast rotation (time of operation from fully closed to reverse fully closed is t1)
・ Low speed (Slow): Slowly rotating (Fully closed to reverse fully closed operating time is t2 (> t1))
In addition to this, the control command can be variably controlled at two tilt speeds.
・ Angular difference (A): The angle difference between the previous time and this time (example: angle difference of 10 degrees or more)
・ Amount of change in angle per rotation (B) ... (example: 3 degrees)
・ Transmission interval (C) (Example: 1 minute)
Number of transmissions (D): = A / B (Example: Horizontal → Fully open (80 degrees) / 3 degrees = 27 times transmission. Specific angle difference, angle change amount, transmission interval exemplified above) It should be noted that the numerical values of the number of transmissions are given for the purpose of improving the understanding of the present invention, and the present invention is not limited to such numerical levels.

  At this time, in the tilt operation at the slow tilt speed, the management device 1 performs stepwise control with a plurality of small-angle tilt amounts when the angle difference is large from the tilt amount based on the current state information. Generate multiple times of control commands and send them in multiple times. More specifically, when the management apparatus 1 wants to rotate slowly, the management apparatus 1 compares the tilt amount based on the current state information with the tilt amount by the current control, and the difference (that is, the angle difference of the tilt angle) is obtained. If it is larger, a small change angle (B) is transmitted several times (D) at a constant interval (C) and the control command is transmitted. Thereby, an abrupt angle change can be made slow. For example, in the above example, 27 transmissions × 1 minute interval = 27 minutes, and since the tilt operation is performed in small increments of 3 degrees from horizontal to full opening over 27 minutes, the brightness change with respect to the usage environment is slightly increased step by step. Thus, the user's discomfort associated with the shielding amount adjustment operation of the electric blind can be reduced. Note that the blind 3-1 that receives an operation signal from the individual switch 5 during the operation by the control command gives priority to the operation signal from the individual switch 5.

(Example 3)
FIG. 11 is a block diagram showing the control operation of Example 3 in the electric blind control system of one embodiment according to the present invention. FIG. 12 is an operation explanatory view of the control operation of Example 3 in the electric blind control system of one embodiment according to the present invention.

  First, referring to FIG. 11, the management apparatus 1 automatically controls the slats in each blind based on a control mode in which the control command generation / transmission means 113 sets a variable tilt speed according to the use environment. A control command including a control parameter designating the tilt speed of 33 is generated and transmitted to the designated relay device 2-1 (step S31).

  Subsequently, before relaying the control command by the control command relay control unit 212, the relay device 2-1 checks the status information of each blind held in the storage unit 22 by the state management unit 211 (step S32).

  Subsequently, the relay device 2-1 analyzes the control command for the control command received from the management device 1 by the control command analysis unit 213, and the embodiment described above based on the control mode set according to the use environment. When a tilt operation with a plurality of tilt speeds is scheduled as in the control parameter (P) of 1, the type of the tilt speed is determined (step S33). In the tilt operation with a fast tilt speed ( (Step S33: No) A control command for one time is generated and transmitted by the control command relay control means 212 (Step S34). In the tilt operation at a low tilt speed (Step S33: Yes), the current control command is transmitted. When there is a large angle difference from the tilt amount based on the status information, the control is performed step by step with multiple small angle tilt amounts. It generates a batch of control commands to transmit a plurality of times by the control command relay control unit 212 (step S35).

  Subsequently, the blind 3-N executes a tilting operation at a tilt speed controlled by the control command for one time by the control command execution means 512, or is controlled by the control command for the plurality of times. The tilt operation is controlled at a stepwise tilt speed with the tilt amount of the angle (step S36).

  In this tilt operation, the blind 3-N controls the stepping motor 9 with a control pattern corresponding to the tilt speed by the tilt speed variable control means 513 (step S37).

  Subsequently, the blind 3-N holds or updates the executed tilt amount of the slat 33 in the storage unit 53 as the state information by the state holding / updating means 514 (step S38), and manages it via the relay device 2-1. Transmit to device 1.

  In the operation of the third embodiment, for example, an operation mode as shown in FIG. 12 can be realized. That is, the management device 1 transmits a control command including a tilt speed control parameter (P) set according to the use environment to the relay devices 2-1 and 2-2, and the relay devices 2-1 and 2-2. If the tilt speed is low, it is divided and relayed to the designated blinds 3-N and 4-M. The designated blinds 3-N and 4-M execute a tilt operation with a variable tilt speed in accordance with the control parameter (P).

For example, the control parameter (P) from the management device 1:
・ High speed (Fast): Fast rotation (time of operation from fully closed to reverse fully closed is t1)
・ Middle speed: Normal rotation (operation time from fully closed to reverse fully closed is t2 (> t1))
・ Low speed (Slow): Slow rotation (T3 (> t2) operating time from fully closed to reverse fully closed)
As a control command variably at two or more or stepless tilt speed,
In addition to the above, the control parameter (P) from the relay device 2 is
・ Angular difference (A): The angle difference between the previous time and this time (example: angle difference of 10 degrees or more)
・ Amount of change in angle per rotation (B) ... (example: 3 degrees)
・ Transmission interval (C) (Example: 1 minute)
Number of transmissions (D): = A / B (Example: Horizontal → Fully open (80 degrees) / 3 degrees = 27 times transmission. Specific angle difference, angle change amount, transmission interval exemplified above) It should be noted that the numerical values of the number of transmissions are given for the purpose of improving the understanding of the present invention, and the present invention is not limited to such numerical levels.

  At this time, in the tilt operation at the slow tilt speed, the relay device 2 is controlled step by step with a plurality of small-angle tilt amounts when the angle difference is large from the tilt amount based on the current state information. Generate multiple times of control commands and send them in multiple times. More specifically, in the case of a control command to be rotated slowly, the relay device 2 compares the tilt amount based on the current state information with the tilt amount by the current control, and the difference (that is, the angle of the tilt angle). When the difference is large, a small change angle (B) is transmitted several times (D) at a constant interval (C), and the control command is transmitted. Thereby, an abrupt angle change can be made slow. For example, in the above example, 27 transmissions × 1 minute interval = 27 minutes, and since the tilt operation is performed in small increments of 3 degrees from horizontal to full opening over 27 minutes, the brightness change with respect to the usage environment is slightly increased step by step. Thus, the user's discomfort associated with the shielding amount adjustment operation of the electric blind can be reduced. Note that the blind 3-1 that receives an operation signal from the individual switch 5 during the operation by the control command gives priority to the operation signal from the individual switch 5.

Example 4
FIG. 13: is a block diagram which shows the control action of Example 4 in the electric blind control system of one Embodiment by this invention. FIG. 14 is an operation explanatory view of the control operation of Example 4 in the electric blind control system of one embodiment according to the present invention.

  First, referring to FIG. 11, the management apparatus 1 automatically controls the slats in each blind based on a control mode in which the control command generation / transmission means 113 sets a variable tilt speed according to the use environment. A control command including a control parameter designating the tilt amount 33 is generated and transmitted to the designated relay device 2-1 (step S41).

  Subsequently, before relaying the control command by the control command relay control unit 212, the relay device 2-1 checks the status information of each blind held in the storage unit 22 by the state management unit 211 (step S42).

  Subsequently, the relay device 2-1 analyzes the control command received from the management device 1 by the control command analysis unit 213 (step S43), and determines the tilt amount based on the current state information and the tilt amount of the control command. Is obtained (step S44), and when this angle difference is less than a predetermined value (step S44: No), a control command for one time is generated by a tilt operation at a high-speed (fast) tilt speed, and the control command is relayed. When the angle difference is greater than or equal to a predetermined value (step S44: Yes), it is transmitted by the control means 212 (step S44: Yes), and the tilt operation is performed at a low angle (Slow) with a small amount of tilt angle for multiple times. Control commands for a plurality of times are generated so as to be controlled, and the control command relay control means 212 transmits them in a plurality of times (steps) 46).

  Subsequently, the blind 3-N executes a tilting operation at a tilt speed controlled by the control command for one time by the control command execution means 512, or is controlled by the control command for the plurality of times. The tilt operation is controlled at a stepwise tilt speed with the tilt amount of the angle (step S47).

  In this tilt operation, the blind 3-N controls the stepping motor 9 with a control pattern corresponding to the tilt speed by the tilt speed variable control means 513 (step S48).

  Subsequently, the blind 3-N holds or updates the executed tilt amount of the slat 33 in the storage unit 53 as the state information by the state holding / updating means 514 (step S49), and manages it via the relay device 2-1. Transmit to device 1.

  In the operation of the fourth embodiment, for example, an operation mode as shown in FIG. 14 can be realized. In other words, the management device 1 transmits a control command including the control parameter (P) of the tilt amount set according to the use environment to the relay devices 2-1 and 2-2, and the relay devices 2-1 and 2-2. Determines the tilt speed from the tilt amount, and when the tilt speed is set to a low speed, the tilt speed is divided and relayed to the designated blinds 3-N and 4-M. The designated blinds 3-N and 4-M execute a tilt operation with a variable tilt speed in accordance with the control parameter (P).

For example, the control parameter (P) from the management device 1:
-As the amount of tilt, the control command can be variably adjusted from the amount of tilt by the relay device 2 at two or more or stepless tilt speeds,
In addition to the above, the control parameter (P) from the relay device 2 is
・ Angular difference (A): The angle difference between the previous time and this time (example: angle difference of 10 degrees or more)
・ Amount of change in angle per rotation (B) ... (example: 3 degrees)
・ Transmission interval (C) (Example: 1 minute)
Number of transmissions (D): = A / B (Example: Horizontal → Fully open (80 degrees) / 3 degrees = 27 times transmission. Specific angle difference, angle change amount, transmission interval exemplified above) It should be noted that the numerical values of the number of transmissions are given for the purpose of improving the understanding of the present invention, and the present invention is not limited to such numerical levels.

At this time, the relay apparatus 2 determines from the tilt amount control parameter (P) from the management apparatus 1,
When the angle difference is large from the tilt amount based on the current state information, a control command for a plurality of times is generated and transmitted in a plurality of times so as to control in a stepwise manner with a small amount of tilt angle for a plurality of times. Thereby, an abrupt angle change can be made slow. For example, in the above example, 27 transmissions × 1 minute interval = 27 minutes, and since the tilt operation is performed in small increments of 3 degrees from horizontal to full opening over 27 minutes, the brightness change with respect to the usage environment is slightly increased step by step. Thus, the user's discomfort associated with the shielding amount adjustment operation of the electric blind can be reduced. Note that the blind 3-1 that receives an operation signal from the individual switch 5 during the operation by the control command gives priority to the operation signal from the individual switch 5.

(Example 5)
FIG. 15 is a block diagram showing the control operation of Example 5 in the electric blind control system of one embodiment according to the present invention. The control operation of the fifth embodiment is an example in which the discrimination of the angle difference and the tilt speed of the first to fourth embodiments is all judged on the control unit 51 side in the blind control unit 50.

  Referring to FIG. 15, the management apparatus 1 automatically controls the slats 33 in the respective blinds based on the control mode in which the control command generation / transmission unit 113 sets the variable tilt speed according to the use environment. A control command including a control parameter designating the tilt amount or tilt speed is generated and transmitted to the designated relay device 2-1 (step S51).

  Subsequently, the relay device 2-1 relays the control command by the control command relay control unit 212 (step S52).

  Subsequently, the blind 3-1 checks the current state information by the function of the control unit 51 (step S53), analyzes the control command, and if the control command is a tilt amount, the current state information The angle difference between the tilt amount based on the control command and the tilt amount of the control command is obtained, and when the angle difference is less than a predetermined value, a tilt operation is performed at a fast tilt speed, and the angle difference is equal to or greater than the predetermined value. If it is large, a tilt operation is performed at a slow tilt speed (step S54). If the control command is a tilt speed, a corresponding tilt operation is performed.

  More specifically, the blind 3-N controls the stepping motor 9 with the control pattern corresponding to the tilt speed by the tilt speed variable control means 513 (step S55).

  Subsequently, the blind 3-N holds or updates the executed tilt amount of the slat 33 in the storage unit 53 as the state information by the state holding / updating means 514 (step S56), and manages it via the relay device 2-1. Transmit to device 1.

  Even in the operation of the fifth embodiment, although the processing load of the blind 3-N is increased, the user's discomfort associated with the shielding amount adjustment operation of the electric blind can be reduced.

  As described above, according to the electric horizontal blind system of the present embodiment, the user's discomfort associated with the operation of adjusting the shielding amount of the electric blind can be reduced. For example, in the electric horizontal blind, when the tilting operation is performed quickly in the electric horizontal blind, if the tilting operation is performed quickly, the environment such as the brightness changes suddenly, and this change in brightness may cause discomfort to the user. Therefore, the slow shielding amount adjustment operation is controlled. Further, for example, when the management device 1 determines that the light has changed from clear to cloudy based on the value of the illuminance meter, when the operation is performed in a horizontal state from a slat angle that blocks direct light, control of the slow shielding amount adjustment operation is performed. I do. In addition, for example, when the management device 1 determines that the light has changed from cloudy to clear based on the value of the illuminance meter, when the operation is performed at an angle that blocks direct light from a horizontal state in order to block direct light, a fast shielding amount Controls the adjustment operation. In addition, for example, the management device 1 controls a slow shielding amount adjustment operation when shifting to a fixed angle such as nighttime fully closed (or horizontal).

  As described above, by setting a change element that is predetermined for a change in the use environment as the control mode so as to be changeable, it is possible to realize a shielding amount adjustment operation adapted to any change in the use environment.

  The present invention has been described above with reference to specific embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications can be made without departing from the technical concept thereof. For example, the blind to be controlled by the management apparatus 1 need not be limited to a horizontal blind. The tilt amount described above is the shielding amount adjustment amount of the shielding material, the elevation position is the shielding position of the shielding material, and the tilt speed is shielded. If applied as an amount adjustment speed, the technique according to the present invention can be applied to various types of electric blinds.

  In the description of the above-described embodiments and examples, an example in which the state information is transmitted to the relay device 2 and the management device 1 each time a blind operation to be controlled by the management device 1 is performed. However, the present invention is not limited to this form. For example, the management device 1 is configured to collect blind state information managed by the relay device 2, and the trigger related to this collection is at the time of a periodic request from the management device 1 or in the relay device 2 It can be configured to collect periodically with a timer. Alternatively, the management device 1 can be configured to constantly collect state information of each blind as a constant monitoring.

  In the description of the above-described embodiments and examples, the control command according to the present invention is a control parameter that can directly or indirectly indicate at least two or more stepless tilt speed differences depending on the use environment. Here, the tilt speed of 2 or more means, for example, a predetermined speed range such as the above-described high speed (Fast), medium speed (Middle), and low speed (Slow). The stepless tilt speed means a variable range of a wider range. For example, the stepping motor 39 can be configured to be controlled at a pulse speed closest to the speed value designated by the administrator. More specifically, the control command includes the value of the pulse speed that actually drives the stepping motor 39 (or a value corresponding to the pulse speed), thereby enabling speed control with a stepless tilt speed. It can be configured as follows.

  According to the present invention, it is possible to reduce user discomfort associated with the shielding amount adjustment operation of the electric blind, which is useful for automatic control of the electric blind associated with the shielding amount adjustment operation.
