Abstract

PROBLEM TO BE SOLVED: To enable a user to handle direction and strength of the wind of a blast system such as an electric fan easily and intuitively.SOLUTION: A system enables the user to manipulate the wind as intended by providing an interactive property to a blast machine. Specifically, three types of instructing methods; a method for drawing a wind blowing path on a display, a method for drawing the wind blowing path in the actual environment (actual space), and a method for controlling the wind by installing an instruction marker at a place are achieved as the interaction methods for instructing the electric fan on the direction and the strength of the wind (including the on/off of the blast).

Description

  The present invention relates to a technique for operating the direction and strength of wind in a blower system.

  Air conditioners such as air conditioners are widely used in homes, offices, stores, and public institutions, but air conditioning is too strong (too effective) or too weak. This is because there is a difference not only in the performance of the air conditioner itself but also in how humans perceive room temperature. For this reason, for example, weakly cooled cars are sometimes installed on trains. Since the air conditioner basically controls the room temperature in units of rooms, it is impossible to realize an air condition according to each user's feeling. Furthermore, depending on the structure of the room, air does not convect and the temperature indicated by the air conditioner may differ from the actual room temperature. This also causes the temperature to be felt differently.

  Thus, there is a problem with the air conditioning system due to the difference in how humans perceive room temperature and the mechanism of the air conditioner. Today we sometimes solve this problem by using a combination of an air conditioner and a fan, such as using a fan to circulate room air or hit a fan. Fans have been used as a tool to cool down before the advent of air conditioners, but today they are used not only in summer but throughout the year and are being used more actively than before. In other words, the role of electric fans is changing from “cooling” to “using the wind”.

  A general electric fan has a swing function that can send the wind evenly within a predetermined angle range, but there may be places where you do not want to blow the wind depending on the structure of the house and the situation of life. . For example, if the wind is sent to the place where the document is placed, the document will be blown away, and it is not preferable to apply the wind to a place where there is a plant such as a flower. On the other hand, when using a fan for drying laundry, it is also necessary to apply wind to a more appropriate place.

However, the conventional electric fan can only adjust the strength of the wind and change the wind direction and the swing angle with a switch or a remote control provided on the main body (see Patent Document 1), and a desired position. It is not possible to perform fine control such as sending wind of desired strength to (or stopping the wind at a predetermined position). In recent years, a fan having a function of detecting a place where a person is present by a sensor and automatically adjusting a wind intensity has been proposed (see Patent Document 2). However, automatic control by a computer does not always match a user's intention. Not necessarily.
Thus, there has never been a fan designed from the viewpoint of “using the wind”.

It is preferable to control the ventilation of the air off. According to this configuration, it is possible to easily indicate not only the direction of the wind but also on / off of the air flow by drawing a line in an area where the wind is desired to be sent and interrupting the line in an area where the wind is not desired to be sent. it can. In addition, by appropriately adjusting the length of the line and the length of the gap, the user creates a special wind (for example, a very weak wind such as a gentle breeze or a fluctuating wind) by an air on / off pattern. It is also possible.

  The path drawing unit may draw the path with a plurality of types of lines, and the control unit preferably switches the strength of the wind of the blower according to the type of the lines. For example, the type of line can be varied depending on the color and thickness. According to this configuration, the strength of the wind can be instructed by a simple operation of appropriately selecting the type of line to be drawn.

A blower system comprising a camera and an indicator marker, wherein the indicator marker is used by a user to move along a path for sending wind in a space in front of the blower The control unit recognizes an instruction marker from an image captured from the camera at a predetermined time interval, and controls the motor so that the direction of the blower changes following the movement of the instruction marker. It is the ventilation system characterized by this.

  According to this configuration, the direction of the wind sent from the blower can be achieved by a simple and intuitive operation in which the user has the indication marker and sequentially moves the indication marker to a position in the real space (real environment) where the wind is to be sent. It is possible to instruct how to change.

Here, the indicator marker is configured to be capable of presenting a plurality of types of markers, and the control unit recognizes the marker presented by the indicator marker from the image, and determines the marker according to the type of marker. It is preferable to switch on / off of the air blower or the strength of the wind. According to this configuration, by changing the type of marker to be presented while moving the indication marker, it is possible to easily indicate not only the direction of the wind but also on / off of the air flow and the strength of the wind.

It is preferable to stop the blower of the blower before. For example, in the case of a fan-type blower, even if the blower is stopped, the wind does not stop immediately, but a residual wind is generated for a while by a fan that rotates by inertia. In this regard, according to the above-described configuration, the remaining air is eliminated or sufficiently reduced until the blower reaches the position of the stop instruction marker by performing the stop control of the air blow before reaching the stop instruction marker. It is possible to prevent the wind from hitting the position of the stop instruction marker.

  In addition, the indication marker includes a continuous ventilation instruction marker for instructing a time for continuously blowing without changing the direction, and when the control unit recognizes the continuous ventilation instruction marker, the blower It is preferable that the motor is stopped so that the direction of the blower does not change from the timing when it is directed to the position of the continuous blow instruction marker until the time indicated by the continuous blow instruction marker elapses. According to this configuration, it is possible to realize continuous air flow to the position of the marker by a simple operation of arranging the continuous air blowing instruction marker.

<First Embodiment>
(System configuration)
With reference to FIG. 1 and FIG. 2, schematic structure of the ventilation system which concerns on 1st Embodiment of this invention is demonstrated. FIG. 1 is an external perspective view of a blower system according to the first embodiment, and FIG. 2 is a functional block diagram of the blower system according to the first embodiment.

  The blower system 1 is roughly composed of an apparatus main body 10 and an operation unit 20. The apparatus main body 10 includes a blower 11, a motor unit 12 that changes the direction of the blower, a control unit 13 that performs control and arithmetic processing of the blower 11 and the motor unit 12, a memory 14, and a camera 15. In this embodiment, in order to control the direction of the blower two-dimensionally, the motor unit 12 includes a Y-axis motor 12Y that rotates in the left-right direction (around the Y-axis in FIG. 1) and a vertical direction (X in FIG. 1). It is composed of two servo motors, an X-axis motor 12X that rotates about the axis). The camera 15 is fixed to the front surface of the blower 11 so that a space in front of the blower 11 (that is, a space for sending wind from the blower 11) can be photographed. The coordinate system has a Z-axis toward the front of the apparatus body 10, an X-axis in the horizontal direction, and a Y-axis in the vertical direction.

  The operation unit 20 includes a touch panel display 21 and an image processing unit (path drawing unit) 22. In the present embodiment, the operation unit 20 and the apparatus main body 10 are connected by a cable 30 and the operation unit 20 can be stored in a pedestal part of the apparatus main body 10. It can also be configured separately. In the case of a separate configuration, the operation unit 20 and the apparatus main body 10 are configured to transmit and receive information by wireless communication. In addition, it can also be used as the operation unit 20 by installing a predetermined program on a tablet PC or a smartphone.

(Instruction method)
The instruction method of the first embodiment is an air blowing instruction method using a metaphor that draws wind. Specifically, when a user draws a path with a stylus on a photographic image taken by the camera 15 using the touch panel display 21 of the operation unit 20, air is blown along the path. . According to this method, the user can easily and intuitively set “where the wind is sent” from the viewpoint of the blower. And because the wind is sent in the order of drawing,
The flow (order) of the blast can also be set.

(Processing flow)
With reference to FIG. 3, an example of the processing flow of the instruction method of the present embodiment will be described in detail.

  The blower system 1 has a teaching mode for instructing a blower pattern (how to change the direction and strength of the wind) using the operation unit 20 and an execution mode for performing blower according to the blower pattern set in the teach mode. Have. The mode switching between the teaching mode and the execution mode can be performed by the operation unit 20 or a switch (not shown) of the apparatus main body 10.

  When switched to the teaching mode, an image is captured from the camera 15 fixed to the front surface of the blower 11 and transmitted to the image processing unit 22 of the operation unit 20. The image processing unit 22 displays the image and necessary GUI (for example, a button for inputting start / end of drawing, a button for selecting a path type, etc.) on the touch panel display 21 (see FIG. 3A). .

  After the user touches the drawing start button, the user can draw a blow path by tracing the photograph with a stylus or a finger (see FIG. 3B). At this time, it is possible not only to draw the path from the start point to the end point with a single line but also to create a path with a plurality of lines. As will be described in detail later, the line portion means that the air is turned on, and the gap between the lines (the non-drawing portion) means that the air is turned off.

  When the user touches the end button after drawing all the lines, the image processing unit 22 generates blow control data based on the drawn path. In the present embodiment, as shown in FIG. 3C, data in which the coordinate values (image coordinate systems x, y) of the drawing points on each line constituting the path are recorded is used as the air blowing control data. These coordinate values are recorded at predetermined time intervals (for example, 100 msec) while the user is drawing a path. That is, as the path is drawn quickly, the number of recorded coordinate values decreases (coarse), and when the path is slowly drawn, the number of recorded coordinate values increases. Therefore, the user can adjust the length of time for sending the wind by appropriately adjusting the drawing speed of the path. The air blowing control data is a data set for each line. FIG. 3C illustrates an example in which a path is configured by two lines because there are two data sets. Here, the image coordinate system may take the center of the image as the origin, and take the x-axis in the horizontal direction and the y-axis in the vertical direction. This makes it easy to convert the coordinate values of the image coordinate system into the rotation angles of the motors 12X and 12Y.

  The generated air blowing control data is transmitted to the control unit 13 of the apparatus body 10 via the cable 30 and registered in the memory 14. This completes the teaching mode.

  When the user switches to the execution mode, the control unit 13 reads the ventilation control data from the memory 14. Note that a plurality of air blow control data may be registered in the memory 14, and the air blow control data desired to be executed by the user may be selected by the operation unit 20 or the like.

The controller 13 outputs an ON signal to the blower 11 and starts blowing, and then reads the x and y coordinate values in order from the beginning of the blow control data at predetermined time intervals, and sets the rotation angles of the motors 12X and 12Y. By converting and outputting a command signal of the rotation angle to the motor unit 12, the direction of the blower 11 is changed along the path. When the execution of the data set corresponding to the first line is completed, the control unit 13 outputs an off signal to the blower 11 and stops blowing. Then, the control part 13 changes the direction of the air blower 11 to the head position of the data set corresponding to the next line, restarts ventilation at the position, and controls the direction of the air blower 11 according to the data set. If there are more than two datasets, the same is done. When the execution of the last data set is completed, the control unit 13 reads the air blow control data in order from the end, and performs air blow control so as to follow the path in reverse order. That is, the loop is executed in the order of the starting point to the end point of the path to the starting point to the end point.

(Advantages of this method)
According to the configuration of the present embodiment, the user can confirm at a glance an area (a space in front of the blower 11) where air can be sent from the blower 11 by an image displayed on the touch panel display 21 of the operation unit 20. . And it is possible to instruct how to change the direction of the wind sent from the blower 11 by a simple and intuitive operation of drawing a path on the image. In addition, since the drawing speed of the path and the change speed of the direction of the blower are controlled to correspond to each other, the change of the direction of the wind can be performed by a simple and intuitive operation in which the user intentionally adjusts the drawing speed of the path. You can direct the speed.

  Furthermore, by combining a plurality of lines, it is possible to easily instruct not only the direction of the wind but also on / off of the air flow. In addition, by appropriately adjusting the length of the line and the length of the gap, the user creates a special wind (for example, a very weak wind such as a gentle breeze or a fluctuating wind) by an air on / off pattern. It is also possible.

  4A to 4D show examples of path drawing. FIG. 4A shows an example in which a path is drawn with one line, and FIG. 4B shows an example in which a path is drawn with a plurality of (five) lines. FIG. 4C shows an example in which a path is drawn in a dotted line shape. In this case, since the on / off of the air is repeated at short time intervals, a very weak wind such as a breeze can be created. FIG. 4D shows an example in which a path is drawn in a spiral shape. In this case, it is possible to send a wind with a slight shift from the center of the wind to the target existing at the center of the spiral. This can be expected to send a soft breeze. This method can also be used in situations where it is desired to apply wind to the surface as in the case of drying laundry.

  The instruction method according to the present embodiment is characterized in that, in order to write a line on a photograph using a display, it is easy to instruct in detail a path to be blown, and a wind type such as a dotted line or a spiral can be devised. In addition, since the path is drawn, there is an advantage that an overall image of where the wind is sent can be grasped, and a plan for how to blow air can be easily made.

  That is, this method is suitable for accurate and systematic ventilation. Therefore, it may be suitable for a complicated environment, such as when the room structure is complicated or there are many things that should not be exposed to the wind. Further, if the operation unit 20 and the apparatus main body 10 are connected via a LAN or the Internet, remote control is possible. Therefore, this method can also be used for the purpose of controlling the wind path by collectively managing from a remote location.

  In the above embodiment, the type of line is not mentioned. However, for example, a plurality of types of lines such as color and thickness can be drawn, and the wind intensity of the blower 11 can be switched according to the type of line. It is also preferable to do so. For example, a method of preparing three types of lines “thin line”, “normal line”, and “thick line” and assigning each to “weak”, “medium”, and “strong” can be easily realized.

Second Embodiment
(System configuration)
With reference to FIG. 5, schematic structure of the ventilation system which concerns on 2nd Embodiment of this invention is demonstrated. FIG. 5 is an external perspective view of the air blowing system according to the second embodiment.

The air blowing system 1 according to the present embodiment includes an apparatus main body 10 and an instruction marker 40. Since the configuration of the apparatus main body 10 is substantially the same as that of the first embodiment, a detailed description is omitted here.

  The instruction marker 40 is used by a user for a blowing instruction. In this embodiment, two AR markers of 5 cm × 5 cm are bonded on both sides and a handle is attached. As shown in FIG. 5, the front surface of the indication marker 40 is a marker (blow-on marker) that uses the fan of the blower 11 as a motif, and the back surface is a marker (blow-off marker) with a cross mark. Of course, the type of marker is not limited to this, and any marker can be used.

(Instruction method)
The instruction method of the second embodiment is an air blowing instruction method using a metaphor as if the wind is manipulated. Specifically, as shown in FIG. 6, when the user holds the indication marker 40 by hand and moves the indication marker 40 along a path for sending wind in the space in front of the blower 11, the blower 11 is moved to the camera 15. The direction marker 40 is recognized and the direction is changed so as to follow. According to this method, the user can intuitively instruct to “send wind here” by moving the indication marker 40 in the real environment. The user can instruct the direction, strength, speed of change, and the like of the wind while confirming the state of the wind sent from the blower 11.

(Processing flow)
With reference to the flowchart of FIG. 7, an example of the processing flow in the teaching mode of the instruction method of this embodiment will be described in detail. Note that the processing of FIG. 7 is executed by the control unit 13 of the apparatus main body 10.

  When the teaching mode is switched by a switch (not shown) or the like of the apparatus body 10, the processing of FIG. 7 is started, and the processing of FIG. 7 is performed at a constant time interval (for example, 100 msec) until the teaching mode is ended by the user. Repeated (step S77).

  First, when the control unit 13 captures an image from the camera 15 (step S70), the control unit 13 recognizes the instruction marker 40 by image analysis and calculates the coordinate value of the instruction marker 40 in the image coordinate system (step S71). Next, the control unit 13 calculates the rotation angle of each of the X-axis motor 12X and the Y-axis motor 12Y for aligning the indication marker 40 with the center of the image based on the coordinate value of the indication marker 40, and sends the command signal to the motor. It outputs to the unit 12 (step S72). Moreover, the control part 13 discriminate | determines the kind of marker of the instruction | indication marker 40 by pattern recognition (step S73), and outputs an ON signal to the air blower 11 in the case of a ventilation on marker (step S74), and turns off in the case of a ventilation off marker. A signal is output to the blower 11 (step S75). And the control part 13 records the information of each angle of the X-axis motor 12X and the Y-axis motor 12Y at that time, and the information which shows on / off of ventilation as ventilation control data (step S76). FIG. 8 shows an example of the air blowing control data, and each row indicates the motor angle and air blowing on / off (1: on, 0: off) every 100 msec. The air blowing control data is registered in the memory 14 as in the first embodiment.

  In the execution mode, the control unit 13 reads the motor angle information and the on / off information of the air blow sequentially from the top of the air blow control data, and controls the motors 12X and 12Y and the blower 11. When the end point of the path is reached, it is preferable to execute the loop by tracing the path in reverse order as in the first embodiment.

(Advantages of this method)
According to the configuration of the present embodiment, the blower can be operated by a simple and intuitive operation in which the user holds the indication marker 40 and sequentially moves the indication marker 40 to a position where the wind is desired to be sent in the real space (real environment). 11 can be used to instruct how to change the direction of the wind sent. In addition, by preparing a plurality of types of markers, it is possible to easily instruct not only the direction of the wind but also on / off of the air flow by changing the type of the marker to be presented while moving the indication marker. In this embodiment, two types of markers, on and off, are used, but three or more types of markers can be used. It is also possible to indicate the wind strength by using a marker corresponding to the wind strength such as weak / medium / strong.

  Since this method gives an instruction to the real space, the correspondence between the wind and the place actually matches. Since air is also blown during pass recording, it can be controlled while feeling the wind, and the correspondence relationship “the strength of this wind at this place” is straightforward and easy to understand. When the instruction marker 40 is moved, the wind follows, so that it feels like operating the wind.

  Further, the distance in the depth direction (Z-axis direction) can also be recognized based on the size of the indication marker 40 on the image. If this is used, the position of the indicator marker 40 (camera, for example) is weakened as the indicator marker 40 is brought closer to the blower 11 and the wind is weakened as the indicator marker 40 is moved away from the blower 11 (or vice versa). It is also possible to indicate the strength of the wind by a distance from 15).

  This method can be easily used when it is desired to send the wind that is intended from the room structure or the like in a situation where the wind should not directly hit the body, such as at bedtime. It can also be used easily when there is a sudden visit, when the wind from the window changes, or when ventilation is needed when the room smells temporarily.

<Third Embodiment>
The blower system 1 according to the present embodiment includes an apparatus main body 10 and an instruction marker 50 shown in FIG. Since the configuration of the apparatus main body 10 is substantially the same as that of the first embodiment, a detailed description is omitted here.

  The instruction marker 50 is for the user to use for blowing instructions. In the second embodiment, the user holds the pointing marker 40 and moves it along the path. However, in the third embodiment, the pointing marker 50 is arranged at an arbitrary position in the space in front of the blower 11. Use it. Therefore, the indication marker 50 is provided with a leg and has a self-supporting structure. Furthermore, the indication marker 50 of this embodiment has a structure in which a marker card 52 on which a marker is drawn is inserted into a frame 51 in which a square window is formed at the center. According to this structure, by replacing the marker card 52, the type (meaning) of the instruction marker 50 can be easily changed, which is very convenient.

  As the instruction marker 50, a strength instruction marker for instructing wind strength, a stop instruction marker for instructing to turn off air blowing, a continuous air blowing instruction marker for instructing time for continuous air blowing without changing the direction, or the like is used. be able to. In the present embodiment, “SOFT” for reducing the strength of the wind, “OFF” for instructing to turn off the air, “6 seconds” for instructing continuous air for 6 seconds, and “3 seconds” for instructing continuous air for 3 seconds. 4 types of markers are used.

(Instruction method)
The instruction method of the second embodiment is a flag instruction type air blowing instruction technique. Specifically, as shown in FIG. 10, flags with indication markers are set at places where the wind should be applied or should not be applied, and the space is scanned by the camera 15 attached to the blower 11 and the flags are followed. The air blowing control is performed.

(Processing flow)
In the air blowing systems of the first and second embodiments, the teaching mode and the execution mode are separated. On the other hand, the air blowing system of the third embodiment does not have a teaching mode, and performs the detection of the instruction marker and the air blowing control based on the detection in real time while air is actually being blown.

  With reference to the flowchart of FIG. 11, an example of the process flow of the ventilation control of this embodiment is described in detail. 11 is executed by the control unit 13 of the apparatus main body 10.

  The control unit 13 outputs a rotation command signal to the motor unit 12 one by one so that the blower 11 swings at a predetermined angle (for example, 160 degrees) in the horizontal direction (around the Y axis) (step S90). ). The control unit 13 captures an image from the camera 15 (step S91), and detects the indication marker 50 by image analysis (step S92). When the pointing marker 50 is detected, the coordinate value of the pointing marker 50 in the image coordinate system is calculated, and the type of the marker is determined by pattern recognition (step S93).

  When the “SOFT” marker is detected, the control unit 13 determines the timing of the blower 11 at the timing when the indication marker 50 reaches the center of the image (that is, the timing when the blower 11 faces the position where the indication marker 50 is disposed). Control is performed to switch the wind intensity to a weak wind (step S94). When the “6 sec” marker is detected, the control unit 13 outputs a stop command to the motor at the timing when the indication marker 50 reaches the center of the image, and stops the swing motion of the blower 11 for 6 seconds (step S <b> 6). S95). As a result, the wind can be continuously sent to the position where the indication marker 50 is arranged for 6 seconds. Similarly, in the case of the “3 sec” marker, the swing motion of the blower 11 is stopped for 3 seconds.

  When the “OFF” marker is detected, the control unit 13 turns off the blower 11 before the timing when the blower 11 faces the position of the indication marker 50 (for example, when the blower 11 is 8 degrees before the position of the indication marker 50). A signal is output and the swing is stopped for 2 seconds (step S96). Even if the blower 11 is stopped, the wind does not stop immediately, but a residual wind is generated for a while by the inertialy rotating fan. However, as described above, the blow stop control is performed before the “OFF” marker is reached. By performing the above, it is possible to prevent the residual wind from hitting the position of the “OFF” marker. However, since the delay occurs by stopping the swing for 2 seconds, it is preferable to increase the rotation amount of the motor twice until the next blowing position.

  In addition, in the place where the instruction | indication marker 50 is not arrange | positioned, normal ventilation is performed (step S92, S97).

(Advantages of this method)
According to the configuration of the present embodiment, the strength of the wind sent from the blower 11 or the stop of the blow can be achieved by a simple and intuitive operation of placing the indication marker 50 at an arbitrary position in the real space (real environment). It is possible to instruct continuous ventilation.

This method is suitable for situations where multiple people are working in a specific place because of the instruction by the flag. For example, in an environment where a person's seat is determined such as in an office, a certain person refuses to blow, and a certain person desires to blow for a longer time. Similarly, by preparing a plurality of types of flags for a seat in a restaurant, the customer can easily change the on / off of the air blowing to the seat and the strength of the wind. In addition to people, by presenting the “OFF” flag on the vase, it is possible to prevent the wind from being applied to the plant, or when the laundry is hung up in the room, the “6 sec” flag is displayed on the laundry hanger. You can also imagine how to hang down and keep the wind on for a long time. In the above embodiment,
Although a simple swing motion around one axis is performed, a more complex swing motion can be set for the blower 11 by using the operation unit as in the first embodiment.
