Description

[Technical Field]

[0001] The present invention relates to a control system for controlling multiple ceiling fans. [Background technology]

[0002] BACKGROUND ART Conventionally, ceiling fans have been known that rotate blades by rotating a motor, thereby generating wind in the vertical direction (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-165612 Summary of the Invention [Problem to be solved by the invention]

[0004] In large spaces such as non-residential environments, multiple ceiling fans may be installed in one space. Conventionally, one ceiling fan is equipped with one remote controller. When multiple ceiling fans were installed in one space, users had to move to each ceiling fan and use each remote controller to set the airflow, which was inconvenient for users. Also, in some cases, each ceiling fan was equipped with a single airflow setting switch, and in this case, users had to set the airflow for each ceiling fan using each setting switch, which was also inconvenient for users and installers.

[0005] As such, the more ceiling fans installed in one space, the more time and effort it takes to set up each one, making the system less user-friendly.

[0006] Therefore, the present invention is intended to solve the above-mentioned conventional problems, and aims to provide a technology that improves the efficiency of setting each ceiling fan when multiple ceiling fans are installed. [Means for solving the problem]

[0007] In order to achieve this objective, the control system of the present invention is a control system for controlling multiple ceiling fans, and is equipped with a system controller that determines the operation details of the multiple ceiling fans, and the first ceiling fan, which is one of the multiple ceiling fans, receives equipment information for the first ceiling fan and total operation information, which is operation information for all of the multiple ceiling fans, only from the system controller, and the ceiling fans other than the first ceiling fan among the multiple ceiling fans receive equipment information and total operation information for that ceiling fan only from one ceiling fan other than the first ceiling fan, and the ceiling fan that transmits the equipment information and total operation information for that ceiling fan transmits the information to only one ceiling fan, thereby achieving the desired objective. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the embodiments shown below are merely examples for embodying the technical concept of the present invention, and the present invention is not limited to the following. In particular, the materials, shapes, components, and the arrangement and relative arrangement of the components described in the embodiments are merely examples, and are not intended to limit the scope of the present invention to those alone. Furthermore, in each drawing, substantially identical components are designated by the same reference numerals, and redundant explanations will be omitted or simplified.

[0011] (Embodiment) First, a control system according to an embodiment of the present invention will be described. The control system according to this embodiment controls a plurality of ceiling fans. Figure 1 is a system schematic diagram of the control system.

[0012] The control system is a system for controlling a plurality of ceiling fans installed in a given space. The control system includes a plurality of ceiling fans 1 and a system controller 100.

[0013] Multiple ceiling fans 1 are installed in a specified space 2 within a building. In this embodiment, as an example, three ceiling fans 1 are installed in the specified space 2. That is, a first ceiling fan 10, a second ceiling fan 20, and a third ceiling fan 30 are installed in the specified space 2 as the multiple ceiling fans 1. Although three ceiling fans are described as an example of the number of ceiling fans in the specified space 2, the number may be more or less than three.

[0014] The system controller 100 controls a plurality of ceiling fans 1, the details of which will be described later.

[0015] First, we will explain ceiling fan 1. Figure 2 is a side view of ceiling fan 1. As shown in Figure 2, ceiling fan 1 includes a main body 3, a support pole 4, a motor 5, blades 6, and a control unit 7. Ceiling fan 1 is attached to a ceiling 8, and functions as a fan that generates an upward or downward airflow by rotating the blades 6.

[0016] The main body 3 has a hollow conical shape and functions as an outer shell that encloses the motor unit 5, the control unit 7, etc. in the hollow space.

[0017] The support pillar 4 is rod-shaped and can be attached at one end to the ceiling 8. It extends downward from the ceiling 8 and supports the main body 3, motor 5, blades 6, and control unit 7. In other words, the main body 3, motor 5, blades 6, and control unit 7 are supported by the support pillar 4.

[0018] Motor unit 5 is a DC (Direct Current) motor that rotates blades 6 attached to support column 4. Motor unit 5 has an outer rotor structure with a stator fixed to support column 4 and a rotor that rotates around the outer periphery of this stator. In FIG. 1 , first ceiling fan 10 has first motor unit 14 as its motor unit, second ceiling fan 20 has second motor unit 24 as its motor unit, and third ceiling fan 30 has third motor unit 34 as its motor unit.

[0019] The blades 6 are rotated by the motor unit 5 to blow air in the vertical direction. A plurality of them are attached to the outer periphery of the motor unit 5 and rotate integrally with the rotor of the motor unit 5.

[0020] The control unit 7 performs various controls on the ceiling fan 1. In Fig. 1, the first ceiling fan 10 has a first control unit 11 as a control unit for the first ceiling fan 10, the second ceiling fan 20 has a second control unit 21 as a control unit for the second ceiling fan 20, and the third ceiling fan 30 has a third control unit 31 as a control unit for the third ceiling fan 30.

[0021] Next, the control system according to this embodiment will be described with reference to Fig. 3, which is a schematic functional block diagram of the control system and its peripheral components.

[0022] The control system includes a system controller 100 .

[0023] The system controller 100 determines the operation details of the plurality of ceiling fans 1, and includes a reception unit 103, a determination unit 102, and a system communication unit 101.

[0024] Receiving unit 103 receives the air volume settings for first ceiling fan 10, second ceiling fan 20, and third ceiling fan 30. For example, an input unit is provided in system controller 100, and the input unit has a user interface that allows the user to input, and receives input such as air volume settings from the user. The air volume settings for first ceiling fan 10, second ceiling fan 20, and third ceiling fan 30 input by the user via the input unit are sent to receiving unit 103.

[0025] The determination unit 102 acquires the air volume settings received by the reception unit 103, and determines the acquired air volume settings as the air volume settings for the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30.

[0026] Note that the determination unit 102 may determine the airflow settings for the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30 based on temperature information or the like within the specified space 2. For example, the higher the temperature of the area in which the ceiling fan 1 is installed, the higher the set airflow of the ceiling fan 1 installed in that area. In this case, the reception unit 103 may not be provided.

[0027] Furthermore, the determination unit 102 may determine the airflow settings for the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30 based on information about people in the specified space 2. For example, the more people there are in an area where the ceiling fan 1 is installed, the higher the airflow setting for the ceiling fan 1 installed in that area. In this case, the reception unit 103 may not be provided.

[0028] The determination unit 102 stores the determined air volume settings of the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30 as the operation information for all of the multiple ceiling fans. Here, the operation information for all of the multiple ceiling fans is defined as the total operation information. In other words, the determination unit 102 stores (determines) the determined air volume settings for the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30 as the total operation information.

[0029] In this embodiment, system controller 100 stores device information for first ceiling fan 10 as device A, device information for second ceiling fan 20 as device B, and device information for third ceiling fan 30 as device C. The airflow setting for first ceiling fan 10 determined by determination unit 102 is airflow a, the airflow setting for second ceiling fan 20 is airflow b, and the airflow setting for third ceiling fan 30 is airflow c. In other words, determination unit 102 stores as total operating information that the airflow setting for device A is airflow a, the airflow setting for device B is airflow b, and the airflow setting for device C is airflow c.

[0030] The system communication unit 101 has a communication function and communicates with a first communication unit 12 (first control unit 11) described later. ) for more details.

[0031] First ceiling fan 10 includes a first control unit 11 and a first motor unit 14. First control unit 11 includes a first communication unit 12 and a first air volume control unit 13.

[0032] The first communication unit 12 has a communication function and receives information from the system communication unit 101. The first communication unit 12 also transmits information to a second communication unit 22 (second control unit 21) described later. Details will be described later.

[0033] First air volume control unit 13 controls the volume of air generated by the blades of first ceiling fan 10. Specifically, first air volume control unit 13 controls first motor unit 14 to control the volume of air generated by the blades of first ceiling fan 10. One control method for controlling the volume of air to a predetermined volume is constant air volume control, but as constant air volume control is a known technique, further detailed description will be omitted.

[0034] Second ceiling fan 20 includes a second control unit 21 and a second motor unit 24. Second control unit 21 includes a second communication unit 22 and a second air volume control unit .

[0035] The second communication unit 22 has a communication function and receives information from the first communication unit 12. The second communication unit 22 also transmits information to a third communication unit 32 (third control unit 31) described later. Details will be described later.

[0036] Second air volume control unit 23 controls the volume of air generated by the blades of first ceiling fan 10. Specifically, second air volume control unit 23 controls second motor unit 24 to control the volume of air generated by the blades of second ceiling fan 20. One control method for controlling the volume of air to a predetermined volume is constant air volume control, but as constant air volume control is a known technique, further detailed description will be omitted.

[0037] Third ceiling fan 30 includes a third control unit 31 and a third motor unit 34. Third control unit 31 includes a third communication unit 32 and a third air volume control unit 33.

[0038] The third communication unit 32 has a communication function and receives information from the second communication unit 22. Details will be described later.

[0039] Third air volume control unit 33 controls the volume of air generated by the blades of third ceiling fan 30. Specifically, third air volume control unit 33 controls third motor unit 34 in order to control the volume of air generated by the blades of third ceiling fan 30. One control method for controlling the air volume to a predetermined volume is constant air volume control, but as constant air volume control is a known technique, further detailed description will be omitted.

[0040] Here, the functional blocks of the system controller 100, the first control unit 11, the second control unit 21, and the third control unit 31 can be realized as hardware by elements or mechanical devices such as a computer CPU (Central Processing Unit), and as software by a computer program, etc., but here they are functional blocks realized by the cooperation of these. Therefore, these functional blocks can be realized in various forms by combining hardware and software.

[0041] Next, the exchange of information between the system controller 100, the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30 will be described in detail.

[0042] As described above, the determination unit 102 stores as total operation information the determined air volume settings of the first ceiling fan 10, the second ceiling fan 20, and the third ceiling fan 30. Specifically, the determination unit 102 stores as total operation information that the air volume setting of device A is air volume a, the air volume setting of device B is air volume b, and the air volume setting of device C is air volume c.

[0043] System controller 100 (system communication unit 101) is connected only to first ceiling fan 10, and transmits device information and total operation information of first ceiling fan 10 only to connected first ceiling fan 10. In other words, system controller 100 transmits device information of first ceiling fan 10 that first ceiling fan 10 is device A, and transmits total operation information (air volume settings) of all devices only to connected first ceiling fan 10.

[0044] In other words, the first ceiling fan 10, which is one of the multiple ceiling fans, receives the equipment information of the first ceiling fan 10 and the total operation information, which is the operation information of all the multiple ceiling fans, from only the system controller 100.

[0045] The information sent from system controller 100 (system communication unit 101) to first ceiling fan 10 (first communication unit 12) will be described with reference to Fig. 4. Fig. 4 is a diagram showing the data structure of information sent from system controller 100 to first ceiling fan 10, and is an example of the data content. As shown in Fig. 4, system controller 100 sends only to first ceiling fan 10 the device information of first ceiling fan 10 that first ceiling fan 10 is device A, and the total operating information that the airflow setting of device A is airflow a, the airflow setting of device B is airflow b, and the airflow setting of device C is airflow c.

[0046] The first ceiling fan 10 receives information sent from the system controller 100. The first ceiling fan 10 is also connected to a second ceiling fan 20, which is a different ceiling fan from the first ceiling fan 10, and transmits device information and total operation information for the second ceiling fan 20 only to the second ceiling fan 20. In other words, the first ceiling fan 10 transmits device information for the second ceiling fan 20 indicating that the second ceiling fan 20 is device B, and total operation information including the operation information (air volume settings) of all devices only to the connected second ceiling fan 20. In other words, the first ceiling fan 10 is not connected to anything other than the system controller 100 and the second ceiling fan 20.

[0047] The information sent from the first ceiling fan 10 (first communication unit 12) to the second ceiling fan 20 (second communication unit 22) will be described with reference to Fig. 5. Fig. 5 is a diagram showing the data structure of the information sent from the first ceiling fan 10 to the second ceiling fan 20, and is an example of the data content. As shown in Fig. 5, the first ceiling fan 10 sends only to the second ceiling fan 20 the device information of the second ceiling fan 20 that the second ceiling fan 20 is device B, and the total operating information that the airflow setting of device A is airflow a, the airflow setting of device B is airflow b, and the airflow setting of device C is airflow c.

[0048] The second ceiling fan 20 receives information sent from the first ceiling fan 10. The second ceiling fan 20 is also connected to a third ceiling fan 30, which is a ceiling fan different from the first ceiling fan 10 and the second ceiling fan 20, and transmits device information and total operation information for the third ceiling fan 30 only to the third ceiling fan 30. In other words, the second ceiling fan 20 transmits device information for the third ceiling fan 30 indicating that the third ceiling fan 30 is device C, and total operation information including the operation information (airflow settings) of all devices only to the connected third ceiling fan 30. In other words, the second ceiling fan 20 is not connected to any fan other than the first ceiling fan 10 and the third ceiling fan 30.

[0049] From the second ceiling fan 20 (second communication unit 22) to the third ceiling fan 30 (third communication unit 32) The information to be sent will be described with reference to Fig. 6. Fig. 6 is a diagram showing the data structure of information sent from second ceiling fan 20 to third ceiling fan 30, and is an example of the data content. As shown in Fig. 6, second ceiling fan 20 sends only to third ceiling fan 30 the device information of third ceiling fan 30 that third ceiling fan 30 is device C, and the total operating information that device A's airflow setting is airflow a, device B's airflow setting is airflow b, and device C's airflow setting is airflow c.

[0050] The third ceiling fan 30 receives the information sent from the second ceiling fan 20 .

[0051] In this way, among the multiple ceiling fans, ceiling fans other than first ceiling fan 10 receive the equipment information and overall operation information of that ceiling fan only from one ceiling fan other than that ceiling fan. Also, the ceiling fan that transmits the equipment information and overall operation information of that ceiling fan transmits the information to only one ceiling fan.

[0052] As can be seen from the above description, the multiple ceiling fans are connected in series, and the overall operation information is transmitted via each of the multiple ceiling fans.

[0053] Next, the control executed by the control system will be explained using the flowchart in Figure 7. Figure 7 is a flowchart showing the flow of control executed by the control system. In the flowchart, numbers are assigned starting with the initial letter S. For example, S1 indicates a processing step. However, the magnitude of the numerical value indicating the processing step has no relation to the processing order.

[0054] First, determination unit 102 acquires the air volume settings received by reception unit 103, and determines the acquired air volume settings as the air volume settings for device A, which is first ceiling fan 10, device B, which is second ceiling fan 20, and device C, which is third ceiling fan 30. In other words, determination unit 102 determines the total operating information.

[0055] Next, system communication unit 101 transmits to first communication unit 12 that first ceiling fan 10 is device A and the total operation information determined by determination unit 102 (S1).

[0056] First communication unit 12 receives information that first ceiling fan 10 is device A and the overall operating information (S2).

[0057] From the received information, first control unit 11 can determine that first ceiling fan 10, which can be controlled by first control unit 11, is itself device A, and that device A should be controlled at airflow rate a. First airflow rate control unit 13 controls first motor unit 14 to control the airflow rate of first ceiling fan 10 to airflow rate a.

[0058] Next, first communication unit 12 transmits to second communication unit 22 information that second ceiling fan 20 is device B and the total operating information determined by determination unit 102 (S3).

[0059] Second communication unit 22 receives information that second ceiling fan 20 is device B and the overall operation information (S4).

[0060] From the received information, second control unit 21 can determine that second ceiling fan 20, which can be controlled by second control unit 21, is itself device B, and that device B should be controlled at airflow rate b. Second airflow rate control unit 23 controls second motor unit 24 to control the airflow rate of second ceiling fan 20 to airflow rate b.

[0061] Next, the second communication unit 22 determines that the third ceiling fan 30 is device C, and The total operating information determined by the communication unit 102 is transmitted to the third communication unit 32 (S5).

[0062] The third communication unit 32 receives information that the third ceiling fan 30 is device C and the overall operation information (S6).

[0063] From the received information, third control unit 31 can determine that third ceiling fan 30, which can be controlled by third control unit 31, is itself device C, and that device C should be controlled at airflow rate c. Third airflow rate control unit 33 controls third motor unit 34 to control the airflow rate of third ceiling fan 30 to airflow rate c.

[0064] This allows efficient setting of each ceiling fan when multiple ceiling fans are installed.

[0065] Here, a comparative example will be described. In this comparative example, multiple ceiling fans are not connected in series. For example, this is the case when information is sent from system controller 100 to multiple ceiling fans (first ceiling fan 10 and second ceiling fan 20). That is, system controller 100 is connected not only to first ceiling fan 10, but also to multiple ceiling fans (first ceiling fan 10 and second ceiling fan 20). In this case, it is assumed that information is sent from system controller 100, just like in the present invention. In this case, system controller 100 sends to all of the multiple connected ceiling fans device information for the connected ceiling fans that the connected ceiling fan is device A, and total operating information that the airflow setting of device A is airflow a, the airflow setting of device B is airflow b, and the airflow setting of device C is airflow c. In other words, first ceiling fan 10 and second ceiling fan 20 both perceive themselves as device A and that they should be controlled at airflow a. In this way, if multiple ceiling fans are not connected individually in series, they will be recognized as the same device and controlled to the same airflow rate. In other words, when multiple ceiling fans are installed, it is not possible to set each ceiling fan individually.

[0066] The same applies to cases where information is sent from one ceiling fan to multiple ceiling fans. For example, consider the case where first ceiling fan 10 sends information to second ceiling fan 20 and third ceiling fan 30. In this case, as in the present invention, assume that information is sent from first ceiling fan 10. In this case, first ceiling fan 10 sends to all of the multiple ceiling fans (second ceiling fan 20 and third ceiling fan 30) the device information of the ceiling fan that sent the information that it is device B, and the overall operating information that device A's airflow setting is airflow a, device B's airflow setting is airflow b, and device C's airflow setting is airflow c. In other words, second ceiling fan 20 and third ceiling fan 30 both understand that they are device B and that they should control device B at airflow b. In this way, if multiple ceiling fans are not connected individually in series, they will be recognized as the same device and controlled to the same airflow rate. In other words, when multiple ceiling fans are installed, it is not possible to set each ceiling fan individually.

[0067] There are ways to configure each ceiling fan in situations where it is not possible to configure each ceiling fan individually, such as the above. For example, the above problem can be solved by assigning each ceiling fan an address to distinguish them, or by setting channels in advance so that each ceiling fan has a different channel. However, channel configuration and address assignment are time-consuming tasks for the installer (user). Channel configuration requires assigning a channel to each device during installation, while address assignment requires the time-consuming task of registering the address in the system controller. With the present invention, the installer (user) simply connects the devices, and the user is spared the trouble of checking and registering addresses. Furthermore, in terms of manufacturing, there is no need to install an interface for channel configuration, and addresses are easily configured. The present invention can be easily realized with a standardized product without adding any additional processing.

[0068] Furthermore, when information is transmitted from system controller 100 to multiple ceiling fans, compared to a system in which system controller 100 is connected one-to-one to each of the multiple ceiling fans so that the system controller 100 can individually set the airflow volume for each, and the device information to be transmitted is determined based on the connection location, the present invention allows the number of connected ceiling fans to be increased simply by changing the device information and total operation information, thereby increasing the number of ceiling fans that can be controlled regardless of the number of connection interfaces of system controller 100. For example, if system controller 100 has only three communication ports, system controller 100 can only connect and control a maximum of three ceiling fans. In other words, the number of communication ports of system controller 100 limits the number of connectable ceiling fans. However, the present invention allows control of all ceiling fans even if the number of connected ceiling fans exceeds the number of communication ports of system controller 100. Although the total operation information for the ceiling fans transmitted from system controller 100 must be changed, this change alone easily increases the number of controllable ceiling fans.

[0069] The present disclosure has been described above based on the embodiments. These embodiments are merely examples, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure. (Summary of the Invention) The control system of the present invention is a control system for controlling multiple ceiling fans, and includes a system controller that determines the operation details of the multiple ceiling fans, and a first ceiling fan, which is one of the multiple ceiling fans, receives equipment information for the first ceiling fan and total operation information, which is operation information for all of the multiple ceiling fans, only from the system controller, and ceiling fans other than the first ceiling fan among the multiple ceiling fans receive equipment information and total operation information for that ceiling fan only from one ceiling fan other than the first ceiling fan, and the ceiling fan that transmits the equipment information and total operation information for that ceiling fan transmits the information to only one ceiling fan.

[0070] This improves the efficiency of setting each ceiling fan when multiple ceiling fans are installed.

[0071] Alternatively, multiple ceiling fans may be connected in series, and the overall operating information may be transmitted via each of the multiple ceiling fans.

[0072] As a result, device information is assigned to each ceiling fan according to the order in which the multiple ceiling fans are connected, so that the relevant operating state can be determined from all the operating information.

[0073] In addition, the system controller may be connected only to the first ceiling fan and transmit the equipment information and total operating information of the first ceiling fan only to the connected first ceiling fan, and the first ceiling fan may be connected to a second ceiling fan that is a different ceiling fan from the first ceiling fan and transmit the equipment information and total operating information of the second ceiling fan only to the second ceiling fan, and may not be connected to anything other than the system controller and the second ceiling fan.

[0074] As a result, device information is assigned to each ceiling fan according to the order in which the multiple ceiling fans are connected, so that the relevant operating state can be determined from all the operating information.

[0075] The system controller also transmits the device information of the first ceiling fan that the first ceiling fan is device A, and the first ceiling fan transmits the device information of the second ceiling fan that the second ceiling fan is device B. The total operation information of all the devices is Good too.

[0076] As a result, device information is assigned to each ceiling fan according to the order in which the multiple ceiling fans are connected, so that the relevant operating state can be determined from all the operating information.

[0077] The first ceiling fan may include a first control unit that controls the airflow rate of the first ceiling fan, and the second ceiling fan may include a second control unit that controls the airflow rate of the second ceiling fan. The system controller may include a determination unit that determines the airflow rate of all of the multiple ceiling fans as total operating information, and a system communication unit that communicates with the first control unit. The system communication unit may transmit to the first control unit information that the first ceiling fan is device A and the total operating information determined by the determination unit, and the first control unit may transmit to the second control unit information that the second ceiling fan is device B and the total operating information.

[0078] This allows device information to be assigned to each ceiling fan according to the order in which multiple ceiling fans are connected, and the appropriate operating state can be determined from all the operating information, allowing the user to achieve the operation they desire.

[0079] The second ceiling fan is connected to a third ceiling fan that is a ceiling fan different from the second ceiling fan, and transmits the equipment information and total operation information of the third ceiling fan only to the third ceiling fan, and does not need to be connected to any other fans than the first and third ceiling fans.

[0080] As a result, device information is assigned to each ceiling fan according to the order in which the multiple ceiling fans are connected, so that the relevant operating state can be determined from all the operating information. [Industrial Applicability]

[0081] The control system according to the present invention is useful as a system capable of controlling a plurality of ceiling fans. [Explanation of symbols]
