Description

[Technical Field]

[0001] The present invention relates to a remote control system configured so that a main device can remotely control a control target device based on a remote control signal transmitted from an operation terminal. [Background technology]

[0002] The following patent documents disclose an electric screen lifting device (hereinafter simply referred to as the "lifting device") that uses a motor to raise and lower a screen, such as a screen for image projection or a roller curtain, using a remote control system. This lifting device employs a configuration in which a screen wound around a winding shaft in a storage case is raised and lowered by the rotation of the winding shaft. It includes a motor that rotates the winding shaft, a motor drive control circuit (hereinafter simply referred to as the "control circuit") that controls the rotation of the winding shaft by the motor, a remote control for remotely controlling the raising and lowering of the screen, and a decoding unit that decodes (identifies the operation content) signals transmitted from the remote control and received by a remote control receiver (hereinafter simply referred to as the "light-receiving unit") and inputs the decoded results into the control circuit. This lifting device also includes a configuration that detects the amount of lift of the screen and adjusts the lifting speed (the speed at which the motor rotates the winding shaft), but a description of these components is omitted here.

[0003] In this lifting device, when an operation such as raising, stopping, or lowering is performed using the remote control, a signal corresponding to the operation is transmitted from the remote control, and the decoding unit decodes the signal received by the light receiving unit and inputs the decoding result to the control circuit. For example, when an operation to raise is performed using the remote control, the decoding unit inputs an up signal to the control circuit, and in response, the control circuit controls the motor to rotate the winding shaft, thereby winding the screen onto the winding shaft. This raises the bottom end of the screen (the portion where the weight is located). Furthermore, when an operation to stop is performed using the remote control, the decoding unit inputs a stop signal to the control circuit, and in response, the control circuit controls the motor to stop the rotation of the winding shaft, thereby stopping the winding of the screen onto the winding shaft. In this way, in this lifting device, the control circuit controls the motor in response to operations using the remote control, allowing the screen to be raised or lowered as desired.

[0004] [Patent Document 1] JP 2000-131765 A (pages 3-5, figures 1-5) Summary of the Invention [Problem to be solved by the invention]

[0005] However, the lifting device disclosed in the above-mentioned patent document has the following problems to be solved.

[0006] Specifically, the lifting device disclosed in the above-mentioned patent document is equipped with a remote control capable of three types of operation: raising, lowering, and stopping, and is configured to raise and lower the screen in response to these three types of operation. With a lifting device configured in this way, when raising the screen to a desired height, an operation to instruct raising must be performed, and when the screen has been raised to the desired height, an operation to instruct stopping must be performed. Similarly, when lowering the screen to a desired height, an operation to instruct lowering must be performed, and when the screen has been lowered to the desired height, an operation to instruct stopping must be performed. For this reason, the lifting device disclosed in the above-mentioned patent document has the problem that these operations are cumbersome.

[0007] Meanwhile, in view of the above-mentioned problems, the applicant has prototyped an elevator device configured to allow three types of operation, for example, "raise to the top," "lower to the bottom," and "raise / lower to the center." As a result, when it is desired to raise the screen to the top, the screen can be raised to the top by a single remote control operation to instruct "raise to the top," when it is desired to lower the screen to the bottom, the screen can be lowered to the bottom by a single remote control operation to instruct "lower to the bottom," and when it is desired to raise / lower the screen to the center, the screen can be raised / lowered to the center by a single remote control operation to instruct "raise / lower to the center."

[0008] However, with this type of device, there are a wide variety of ways and to what extent the screen can be raised and lowered. For example, some users and locations may want the screen to be raised only 10 cm from the bottom, while others may want it to be raised 1 m from the bottom. When considering use by all users and locations, there are countless possible control modes. Therefore, even if the number of control modes that can be supported is limited based on the average usage environment, it is necessary to provide a remote control with numerous operation switches that can be operated to correspond to those control modes. This increases the size of the remote control, impairs portability, and makes it difficult to identify and operate the switch that commands raising and lowering in the desired control mode. Furthermore, it is difficult to provide switches that correspond to all possible control modes in various usage environments, and depending on the usage environment, the lifting device may become inconvenient, unable to raise and lower the screen in the desired control mode.

[0009] As described above, the configurations of the lifting devices disclosed in the above patent documents and the configuration of the lifting device prototyped by the applicant have the problem that it is difficult to easily raise and lower the screen in a desired control manner under various usage environments. Note that although the explanation has been given using a screen lifting device as an example, similar problems to those present in the above lifting devices also arise when remotely operating various devices such as lighting fixtures and air conditioners.

[0010] The present invention has been made in consideration of the above-mentioned problems to be solved, and its main object is to provide a remote control system that can easily control controlled devices in various control modes required for each usage environment. [Means for solving the problem]

[0011] In order to achieve the above object, the remote control system described in claim 1 comprises an operating terminal having a terminal-side control unit and a terminal-side wireless communication unit, and a main unit having a main unit-side control unit and a main unit-side wireless communication unit, and the main unit-side control unit controls the operation of a controlled device based on a remote control signal transmitted from the terminal-side wireless communication unit and received by the main unit-side wireless communication unit, wherein the operating terminal comprises a code reader, and the terminal-side control unit is configured to be able to transmit, from the terminal-side wireless communication unit, code data capable of identifying a code of a code display read by the code reader as the remote control signal, and the main unit comprises a memory unit that stores control data capable of identifying a correspondence between a predetermined control mode of the controlled device and the code data, and the main unit is configured to be able to identify, based on the control data, the control mode corresponding to the code data transmitted from the terminal-side wireless communication unit and received by the main unit-side wireless communication unit, and control the operation of the controlled device in the identified control mode.

[0012] The remote control system of claim 2 is the remote control system of claim 1, wherein the operation terminal is provided with an operation unit capable of executing at least one of a read start operation that causes the code reader to start reading the code display, and a transmission start operation that causes the terminal-side wireless communication unit to start transmitting the code data corresponding to the code of the code display read by the code reader.

[0013] The remote control system of claim 3 is the remote control system of claim 1 or 2, in which an alarm unit is arranged in at least one of the operation terminal and the main device to notify at least one of reception completion information that can identify that the code data has been received by the main body side wireless communication unit and control start information that can identify that the main body side control unit has controlled the operation of the controlled device in the identified control mode. [Effects of the Invention]

[0014] The remote control system described in claim 1 is a remote control system comprising an operating terminal and a main body device, in which the main body side control unit controls the operation of the controlled device based on a remote control signal transmitted from the terminal side wireless communication unit and received by the main body side wireless communication unit, wherein the operating terminal comprises a code reader, and the terminal side control unit is configured to be able to transmit code data capable of identifying the code of the read code display from the terminal side wireless communication unit as a remote control signal, the main body device comprises a memory unit that stores control data capable of identifying the correspondence between a predetermined control mode of the controlled device and the code data, and the main body side control unit is configured to identify the control mode corresponding to the received code data based on the control data, and to control the operation of the controlled device in the identified control mode.

[0015] Therefore, according to the remote control system of claim 1, an operation menu is prepared on which the minimum necessary code indications corresponding to the control modes to be implemented are printed, and the controlled device can be operated by reading the code indication of the desired control mode using an operation terminal (code reader). In this case, since the creation of the operation menu (printing the code indication) itself can be performed at low cost, multiple types of operation menus can be prepared depending on the usage environment of the controlled device and the user's preferences, and a control environment with different content and number of executable control modes can be provided without changing the configuration of the main device or the operation terminal. Furthermore, since the operation of the controlled device can be controlled by a simple operation of just reading the code indication using the operation terminal (code reader), even an inexperienced person can easily operate the controlled device.

[0016] In the remote control system of claim 2, the operating terminal includes an operating unit capable of executing at least one of a read start operation for starting reading of a code display by a code reader, and a transmission start operation for starting transmission of code data corresponding to the code of the code display read by the code reader from the terminal-side wireless communication unit. Therefore, unlike a configuration in which a code display is automatically read and code data is automatically transmitted, the remote control system of claim 2 preferably prevents a situation in which an unintended code display is read and code data of a corresponding control mode is transmitted, thereby preventing the controlled device from being operated in an unintended control mode.

[0017] In the remote control system of claim 3, a notification unit is provided in at least one of the operation terminal and the main device, which notifies at least one of reception completion information that can specify that the main device wireless communication unit has received the code data and control start information that can specify that the main device control unit has controlled the operation of the controlled device in the specified control mode. Therefore, the remote control system of claim 3 can preferably avoid a situation where the main device does not control the controlled device even though the control of the controlled device is instructed by reading the code display. [Brief explanation of the drawings]

[0018] [Figure 1] 1 is a diagram showing the configuration of a remote control system 1 and a roll curtain 100 that is an object of control by the remote control system 1. FIG. [Figure 2] FIG. 2 is an explanatory diagram for explaining an example of control data D0. [Figure 3] FIG. 2 is an explanatory diagram for explaining an example of an operation menu M1. [Figure 4] FIG. 10 is an explanatory diagram for explaining an example of an operation menu M2. DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, an embodiment of the "remote control system" will be described with reference to the accompanying drawings.

[0020] The remote control system 1 shown in Fig. 1 is an example of a "remote control system" and includes a main device 2 and an operation terminal 3, and is configured to enable remote control of a roller curtain 100 using an operation menu M, which will be described later. In this case, the roller curtain 100 is an example of a "device to be controlled," and includes a curtain 101 wound around a winding shaft 101a, a motor 102 that rotates the winding shaft 101a, and a power supply unit (motor drive control unit) 103 that supplies power to the motor 102 to rotate the winding shaft 101a, and is configured to be able to open and close (raise and lower) the curtain 101.

[0021] The main device 2 is an example of a "main device" and includes a communication unit 11, an operation unit 12, a control unit 13, and a memory unit 14, and is configured to be able to control the operation of a "control target device" such as the roller curtain 100 based on a "remote operation signal" transmitted from the operation terminal 3. The communication unit 11 corresponds to a "main device side wireless communication unit," and is configured, for example, to be a short-range wireless communication module conforming to the Bluetooth (registered trademark) standard, and is configured to be able to transmit and receive various data to and from compatible devices such as the operation terminal 3. The operation unit 12 is configured, for example, to have an operation switch that commands the raising and lowering of the curtain 101, and is configured to be able to output an operation signal corresponding to the switch operation to the control unit 13.

[0022] The control unit 13 is an example of a "main body side control unit" and controls the main body device 2 as a whole, and also controls the operation of the roller curtain 100 (rotation and stopping of the motor 102) by outputting a control signal S to the roller curtain 100 (power supply unit 103) as described below. Specifically, when the communication unit 11 receives code data D1 transmitted from the operation terminal 3 as described below, the control unit 13 causes the communication unit 11 to transmit reception completion data D2 indicating that the code data D1 has been successfully received to the operation terminal 3. Furthermore, the control unit 13 identifies a control mode corresponding to the code data D1 received by the communication unit 11 based on control data D0 stored in the storage unit 14, and outputs a control signal S that controls the operation of the roller curtain 100 in the identified control mode. The storage unit 14 is an example of a "storage unit" and stores the control data D0 shown in FIG. 2 and the like.

[0023] In this case, the control data D0 is an example of "control data" and is generated so as to be able to identify the correspondence between control modes that specify the amount of lift, such as "fully open," "up 5 cm," "up 10 cm," etc., which are examples of "control modes of predefined controlled devices," and control modes that specify the amount of descent, such as "fully closed," "down 5 cm," "down 10 cm," etc., and control modes that specify the open and closed positions, such as "1 / 10 open," "2 / 10 open," "1 / 4 open," etc., and the codes "U001," "U001," "U002," etc., which are examples of "codes (code data)" individually associated with these control modes, and the codes "D000," "D001," "D002," etc., and the codes "P000," "P001," "P002," etc.

[0024] It should be noted that the "control modes" and "codes" of the control data D0 shown in the figure are simplified examples to facilitate understanding of the configuration of the "remote control system," and the "control modes" and "codes" defined in an actual "remote control system" are defined appropriately depending on the "device to be controlled" and the operation to be achieved in its usage environment. Also, the control data D0 records information (in this example, which controls the roller curtain 100 by transmitting a control signal S, the content of the control signal S to be transmitted) that can identify the control content (how power is supplied from the power supply unit 103 to the motor 102) of the roller curtain 100 (power supply unit 103) associated with each defined "control mode."

[0025] On the other hand, the operation terminal 3 is an example of an "operation terminal" and includes a code reader 21, a communication unit 22, an operation unit 23, a speaker 24, an indicator 25, and a control unit 26. The code reader 21 is an example of a "code reader" and reads two-dimensional codes Ca, Cb..., C1, C2... (hereinafter also referred to as "two-dimensional code C" when not distinguished) printed on an operation menu M1 shown in FIG. 3 or an operation menu M2 shown in FIG. 4 (hereinafter also referred to as "operation menu M" when not distinguished), and outputs code data D1 that can identify the read result (code) to the control unit 26. In this case, the operation menu M is, for example, configured as a sheet body that is printed in advance by the manufacturer or user of the remote operation system 1 depending on the usage environment.

[0026] For example, the operation menu M1 shown in Figure 3 is an example of a sheet body printed with the ability to control the roller curtain 100 in three control modes: "fully open," "half open," and "fully closed." The operation menu M1 is printed with a target device display T1 consisting of the character string "south window curtain," which can identify the location where the roller curtain 100, which is remotely controlled by the remote control system 1, is installed, two-dimensional codes Ca, Cb, and Cc (an example of a "code display"; hereinafter, when these are not distinguished, they are also referred to as "two-dimensional code C," including the two-dimensional codes C1 to C10 described below) indicating the codes "U000," "P007," and "D000," which are defined corresponding to the control modes of "fully open," "half open (1 / 2 open)," and "fully closed," and control mode displays Pa, Pb, and Pc (hereinafter, when these are not distinguished, they are also referred to as "control mode displays P," including the control mode displays P1 to P10 described below) indicating the control modes corresponding to the codes of the two-dimensional codes Ca, Cb, and Cc.

[0027] 4 is an example of a sheet body printed so that the roll curtain 100 can be controlled in 10 different control modes: "down 5 cm," "down 25 cm," "fully closed," "up 5 cm," "up 25 cm," and "fully open." The operation menu M2 shown in FIG. 4 corresponds to the control modes of "down 5 cm," "down 25 cm," "fully closed," "up 5 cm," "up 25 cm," and "fully open." The operation menu M2 ...down 25 cm," "fully closed," "up 5 cm," "up 25 cm," and "fully open." The operation menu M2 corresponds to the control modes of "down 5 cm," "down 25 cm," "down 25 cm," "fully closed," "up 25 cm," and "fully open." The operation menu M2 corresponds to the control modes of "down 5 cm," "down 25 cm," "down 25 cm," "fully closed," "up 25 cm," and "fully open." The operation menu M2 corresponds to the control modes of "down 5 cm," Printed on the display are two-dimensional codes C1, C2, ·· C5, C6, C7, ·· C10 (another example of "code display") indicating the codes "D001", "D005", ·· "D000", "U001", "U005", ·· "U000" defined by the above, and control mode displays P1, P2, ·· P5, P6, P7, ·· P10 consisting of character strings indicating the control modes corresponding to the codes of the two-dimensional codes C1, C2, ·· C5, C6, C7, ·· C10, including "down 5 cm", "down 25 cm", ·· "fully closed", "up 5 cm", "up 25 cm", ·· "fully open".

[0028] In this case, the control modes executable by this remote control system 1 are not limited to the control modes such as the example of the control data D0 shown in Fig. 2, but depending on the specifications of the controlled device (such as the roller curtain 100), it is possible to control it in hundreds to thousands of different control modes. Therefore, by arbitrarily selecting the control mode that needs to be implemented according to the specifications and installation location of the roller curtain 100 and the user's requests, and creating an operation menu M by printing a two-dimensional code C and a control mode display P according to the selected control mode, it is possible to provide a very easy-to-read operation menu M that does not include a two-dimensional code C or a control mode display P corresponding to a control mode that is not scheduled to be implemented.

[0029] In the example of the operation menu M shown in Figures 3 and 4, a two-dimensional code C of "QR Code (registered trademark)" is used, which is an example of "code display", but "code display" is not limited to this, and stacked two-dimensional codes such as "PDF417 (registered trademark)" and "CODE49 (registered trademark)", matrix two-dimensional codes such as "DataMatrix (registered trademark)" and "VeriCode (registered trademark)", and one-dimensional codes such as "barcode" can also be used.

[0030] The communication unit 22 corresponds to a "terminal-side wireless communication unit" and, for example, is configured as a short-range wireless communication module conforming to the Bluetooth (registered trademark) standard, similar to the communication unit 11 of the main unit 2, and is configured to be able to transmit and receive various data to and from compatible devices such as the main unit 2. The operation unit 23 corresponds to an "operation unit" and, for example, includes an operation switch capable of a "transmission start operation" that starts transmission of code data D1 corresponding to the code of the two-dimensional code C read by the code reader 21 to the main unit 2, and outputs an operation signal corresponding to the switch operation to the control unit 26. Note that the operation unit 23 may be provided with an operation switch capable of a "reading start operation" that starts reading of the two-dimensional code C by the code reader 21 instead of (or in addition to) the operation switch.

[0031] The speaker 24, together with the indicator 25, constitutes an "alert section," and is configured, for example, to be able to output a beep sound (an example of "reception completion information") to notify the user that the code data D1 has been normally received by the communication section 11 of the main device 2 as will be described later, under the control of the control section 26. Note that, instead of (or in addition to) the above configuration, the speaker 24 can also be configured to output a beep sound (an example of "control start information") to notify the user that the control section 13 of the main device 2 has controlled the operation of the roller curtain 100 or the like in a control mode corresponding to the code data D1 transmitted from the operation terminal 3, under the control of the control section 26.

[0032] As an example, the indicator 25 is configured to perform a predetermined operation such as turning on, turning off, or blinking (another example of "reception completion information") under the control of the control unit 26 when the code data D1 is normally received by the communication unit 11 of the main device 2 as described below. Note that instead of (or in addition to) the above configuration, the indicator 25 can also be configured to perform a predetermined operation such as turning on, turning off, or blinking (another example of "reception completion information") under the control of the control unit 26 when the control unit 13 of the main device 2 controls the operation of the roller curtain 100 or the like in a control mode corresponding to the code data D1 transmitted from the operation terminal 3.

[0033] The control unit 26 is an example of a "terminal-side control unit" and controls the operation terminal 3 in an overall manner. Specifically, when any of the two-dimensional codes C is read by the code reader 21 and code data D1 is output from the code reader 21, and a "transmission start operation" is performed on the operation unit 23, the control unit 26 causes the communication unit 22 to transmit the code data D1 as a "remote operation signal" to the main device 2. Furthermore, when reception completion data D2 is transmitted from the main device 2 after the transmission of the code data D1 and received by the communication unit 22, the control unit 26 causes the speaker 24 and the indicator 25 to notify that the code data D1 transmitted from the operation terminal 3 has been successfully received by the main device 2.

[0034] Next, a method of using the remote control system 1 (control of the operation of the roller curtain 100 by the remote control system 1) will be described with reference to the attached drawings. Note that it is assumed that pairing (setting to a state where mutual communication is possible) between the communication unit 11 of the main device 2 and the communication unit 22 of the operation terminal 3 has been completed, and detailed description thereof will be omitted.

[0035] When controlling the operation of the roller curtain 100 with this remote control system 1, the control unit 13 of the remote control system 1 is connected to the power supply unit 103 of the roller curtain 100, and an operation menu M is prepared on which a two-dimensional code C corresponding to the required control mode is printed, based on the specifications of the roller curtain 100 (such as the length of the curtain 101) and the user's requests. In this case, for example, if control in three control modes, "fully open," "half open," and "fully closed," is desired and no other control modes are required, an operation menu M1 shown in Figure 3 is prepared. The prepared operation menu M1 can be fixed to a wall or the like in the installation space of the roller curtain 100 and the remote control system 1, or stored in a desired storage location together with the operation terminal 3, so that the two-dimensional code C can be read by the operation terminal 3.

[0036] As an example, when the roll curtain 100 is to be transitioned from a fully closed state (a state in which the curtain 101 is lowered to the bottom) to a fully open state (a state in which the curtain 101 is raised to the top), the user holds the operation terminal 3 in his / her hand and causes the code reader 21 to read the two-dimensional code Ca on the operation menu M1. At this time, the code reader 21 outputs code data D1, which is the code "U000" that is the result of reading the two-dimensional code Ca, and the control unit 26 outputs a beep from the speaker 24 to notify that one of the two-dimensional codes C has been read by the code reader 21. The user recognizes from the output of this beep that the reading of the two-dimensional code Ca has been completed and operates the transmission start switch of the operation unit 23 (execution of a "transmission start operation"). In response to this, the control unit 26 causes the communication unit 22 to transmit the code data D1 to the operation terminal 3.

[0037] In the main device 2, the communication unit 11 receives the code data D1 transmitted from the operation terminal 3 and outputs it to the control unit 13. The control unit 13 then causes the communication unit 11 to transmit reception completion data D2, indicating that the code data D1 has been successfully received, to the operation terminal 3. In the operation terminal 3, the communication unit 22 receives the reception completion data D2 transmitted from the main device 2 and outputs it to the control unit 26. The control unit 26 then outputs a beep from the speaker 24 and, for example, flashes the indicator 25, indicating that the main device 2 has successfully received the code data D1. If the user performs a "transmission start operation" after the code reader 21 reads the two-dimensional code Ca but is not notified that the main device 2 has successfully received the code data D1, the user can have the code reader 21 read the two-dimensional code Ca and perform the "transmission start operation" again. This prevents the roller curtain 100 from operating and remaining in the "fully closed" position despite a command to "fully open."

[0038] Meanwhile, in the main device 2, in parallel with the process of causing the communication unit 11 to transmit the reception completion data D2 to the operation terminal 3, the control unit 13 identifies, based on the control data D0, the control mode associated with the code of the code data D1 received by the communication unit 11. At this time, it identifies that control has been instructed in the control mode of "fully open" associated with the code "U000," and outputs a control signal S to the roller curtain 100 to transition to "fully open." In response to this, the power supply unit 103 in the roller curtain 100 supplies power to the motor 102 in accordance with the control signal S from the main device 2, thereby raising the curtain 101 to the top. This completes the transition of the roller curtain 100 to "fully open."

[0039] As another example, when the roll curtain 100 is to be shifted from a fully open state to a half-open state (a state in which the curtain 101 is lowered to the center), the user holds the operation terminal 3 in his / her hand and causes the code reader 21 to read the two-dimensional code Cb of the operation menu M1. At this time, the code reader 21 outputs code data D1, which is the code "P007" that is the result of reading the two-dimensional code Cb, and the control unit 26 outputs a beep from the speaker 24 to notify that one of the two-dimensional codes C has been read by the code reader 21. The user recognizes from the output of this beep that the reading of the two-dimensional code Cb has been completed and operates the transmission start switch of the operation unit 23 (execution of a "transmission start operation"). In response to this, the control unit 26 causes the communication unit 22 to transmit the code data D1 to the operation terminal 3.

[0040] Furthermore, in the main device 2, the communication unit 11 receives the code data D1 transmitted from the operation terminal 3 and outputs it to the control unit 13, and the control unit 13 causes the communication unit 11 to transmit reception completion data D2, which notifies the operation terminal 3 that the code data D1 has been successfully received. Furthermore, in the operation terminal 3, the communication unit 22 receives the reception completion data D2 transmitted from the main device 2 and outputs it to the control unit 26, and the control unit 26 outputs a beep from the speaker 24 and flashes the indicator 25, thereby notifying the main device 2 that the code data D1 has been successfully received.

[0041] Meanwhile, in the main device 2, in parallel with the process of causing the communication unit 11 to transmit reception completion data D2 to the operation terminal 3, the control unit 13 identifies, based on the control data D0, the control mode associated with the code of the code data D1 received by the communication unit 11. At this time, it identifies that control has been instructed in the control mode of "half open" associated with the code "P007," and outputs a control signal S to the roller curtain 100 to transition to "half open." In response to this, the power supply unit 103 in the roller curtain 100 supplies power to the motor 102 in accordance with the control signal S from the main device 2, thereby lowering the curtain 101 to the center. This completes the transition of the roller curtain 100 to "half open."

[0042] Although detailed explanation will be omitted, when the roller curtain 100 is to be transitioned from the "fully open" or "half open" state to "fully closed," the code reader 21 is caused to read the two-dimensional code Cc of the operation menu M1 and a "transmission start operation" is executed. As a result, the roller curtain 100 is transitioned to "fully closed" under the control of the main unit 2, in the same manner as when transitioning to "fully open" or "half open" as described above. In this way, with this remote control system 1, it is possible to transition the roller curtain 100 to any state by simply reading the two-dimensional code C of the desired control mode from the three control modes of "fully open," "half open," and "fully closed" and executing the "transmission start operation."

[0043] On the other hand, depending on the installation environment of the roller curtain 100, the user's preferences, and the like, it may be desired to open / close (raise / lower) the roller curtain 100 in a variety of control modes other than the above three types of control modes. In this case, instead of the operation menu M1, an operation menu M2 or the like is prepared on which a two-dimensional code C is printed according to the control mode to be executed. As a result, for example, when it is desired to raise the roller curtain 100 (curtain 101) by 5 cm, the operation terminal 3 (code reader 21) reads the two-dimensional code C6 and executes a "transmission start operation," so that a control signal S is output from the main device 2 (control unit 13) to the roller curtain 100, and the curtain 101 is raised by 5 cm. When it is desired to lower the roller curtain 100 (curtain 101) by 50 cm, the operation terminal 3 (code reader 21) reads the two-dimensional code C3 and executes a "transmission start operation," so that a control signal S is output from the main device 2 (control unit 13) to the roller curtain 100, and the curtain 101 is lowered by 50 cm.

[0044] As described above, in the remote control system 1 of this example, a desired control mode can be selected from the many control modes recorded in the control data D0 stored in the memory unit 14 of the main device 2, i.e., from the many control modes executable by the main device 2, and an operation menu M printed with the corresponding two-dimensional code C is prepared, making it possible to operate the roller curtain 100 in a manner that suits the installation environment of the roller curtain 100, the user's preferences, etc. As a result, for example, depending on the manager's level regarding the raising and lowering of the roller curtain 100, a person who is only allowed to control two types of control, "fully open" and "fully closed," can use the operation menu M printed with only the two corresponding two-dimensional codes C, and a person who needs to fine-tune the raising and lowering position of the curtain 101 can use the operation menu M printed with many two-dimensional codes C that specify the amount of lowering, the amount of raising, and the raising and lowering position. This makes it possible to control the roller curtain 100 in the necessary and sufficient control mode without changing the specifications of the main device 2 or the operation terminal 3.

[0045] In this way, this remote control system 1 comprises a main unit 2 and an operation terminal 3, and the control unit 13 controls the operation of the roller curtain 100 based on a remote control signal transmitted from the communication unit 22 and received by the communication unit 11. The operation terminal 3 comprises a code reader 21, and the control unit 26 is configured to be able to transmit code data D1 capable of identifying the code of the read two-dimensional code C as a remote control signal from the communication unit 22. The main unit 2 comprises a memory unit 14 that stores control data D0 capable of identifying the correspondence between a predetermined control mode of the roller curtain 100 and the code data D1, and the control unit 13 is configured to identify the control mode corresponding to the received code data D1 based on the control data D0 and control the operation of the roller curtain 100 in the identified control mode.

[0046] Therefore, with this remote control system 1, the roll curtain 100 can be operated by preparing an operation menu M on which the minimum necessary two-dimensional codes C corresponding to the control modes to be implemented are printed, and reading the two-dimensional code C of the desired control mode with the operation terminal 3 (code reader 21). In this case, since the creation of the operation menu M (printing the two-dimensional code C) itself can be carried out at low cost, multiple types of operation menus M can be prepared depending on the usage environment of the roll curtain 100 and the user's preferences, and a control environment with different content and number of executable control modes can be provided without changing the configuration of the main device 2 or the operation terminal 3. Furthermore, since the operation of the roll curtain 100 can be controlled by the simple operation of just reading the two-dimensional code C with the operation terminal 3 (code reader 21), even an inexperienced person can easily operate the roll curtain 100.

[0047] Furthermore, in this remote control system 1, the operation terminal 3 is provided with an operation unit 23 that can execute at least one of a read start operation that causes the code reader 21 to start reading the two-dimensional code C, and a transmission start operation that causes the communication unit 22 to start transmitting code data D1 corresponding to the code of the two-dimensional code C read by the code reader 21 (as an example, a read start operation). Therefore, unlike a configuration in which the two-dimensional code C is automatically read and the code data D1 is automatically transmitted, this remote control system 1 can preferably avoid a situation in which an unintended two-dimensional code C is read and code data D1 of a corresponding control mode is transmitted, thereby preventing the roller curtain 100 from being operated in an unintended control mode.

[0048] Furthermore, in this remote control system 1, a "notification unit" that notifies at least one of reception completion information, which can identify that the code data D1 has been received by the communication unit 11, and control start information, which can identify that the control unit 13 has controlled the operation of the roller curtain 100 in the control mode identified (for example, the reception completion information), is provided in at least one of the operation terminal 3 and the main unit 2 (for example, a speaker 24 and an indicator 25 are provided in the operation terminal 3). Therefore, according to this remote control system 1, it is possible to preferably avoid a situation in which the main unit 2 does not control the roller curtain 100 despite an instruction to control the roller curtain 100 being given by reading the two-dimensional code C.

[0049] The configuration of the "remote control system" is not limited to the above-described example of the configuration of the remote control system 1. For example, the "main body side wireless communication unit" and the "terminal side wireless communication unit" are described as having communication units 11, 22 configured as short-range wireless communication modules conforming to the Bluetooth standard, but the wireless communication between the "main body side wireless communication unit" and the "terminal side wireless communication unit" is not limited to this, and a configuration in which communication is performed by wireless LAN such as Wi-Fi (registered trademark) or infrared communication such as IR can also be adopted.

[0050] In addition, we have explained examples of a configuration in which the transmission of code data D1 corresponding to the code of the two-dimensional code C read by the code reader 21 to the main device 2 is started when a ``start transmission operation'' is performed on the operation unit 23, and a configuration in which the reading of the two-dimensional code C by the code reader 21 is started when a ``start reading operation'' is performed on the operation unit 23, but it is also possible to adopt a configuration in which the transmission of code data D1 corresponding to the code of the read two-dimensional code C to the main device 2 is automatically started when the reading of any two-dimensional code C by the code reader 21 is completed, without performing a ``start transmission operation'' or a ``start reading operation.''

[0051] Furthermore, although an example has been described in which the operation terminal 3 has the speaker 24 and the indicator 25 as an "alarm unit", it is also possible to adopt a configuration in which an "operation terminal" has only one of the speaker 24 and the indicator 25 as an "alarm unit", or an "operation terminal" has no "alarm unit". Furthermore, although an example has been described in which an "alarm unit (speaker 24 and indicator 25)" is provided in the operation terminal 3, instead of (or in addition to) such a configuration, it is also possible to provide an "alarm unit" in the "main device".

[0052] In addition, although an example of controlling the operation of a roller curtain 100, which is an example of a "controlled device," has been described, the "controlled device" is not limited to this, and a configuration similar to that of the remote control system 1 described above can be adopted when remotely controlling various devices such as lighting fixtures, air conditioners, washing machines, refrigerators, and televisions.
