  FIG. 1 is a diagram illustrating an example of a system according to the present embodiment. As shown in FIG. 1, the system according to this example includes a local node 1, a server 2, and a remote control device 3. The local node 1 and the server 2 are connected to each other through the Internet. The server 2 and the remote control device 3 are also connected to each other through the Internet.

  As illustrated in FIG. 2, the local node 1 includes a sensor group 10, a control target unit 11, a control unit 12, and a management unit 13. As shown in FIG. 2, the sensor group 10, the control unit 12, and the management unit 13 are connected to each other for exchanging information, which will be described later. The control unit 12 and the control target unit 11 are also connected to each other. In FIG. 2, an arrow is directed to the information output destination on the line segment representing the connection, but information exchange is not limited to that direction.

  The sensor group 10 is composed of one or a plurality of sensors for obtaining information such as temperature and humidity inside and outside the facility. Information obtained from this sensor or sensors (hereinafter referred to as sensor value or environmental information) includes temperature, humidity, carbon dioxide concentration, solar radiation, rainfall, wind direction, wind speed, soil temperature, soil moisture content. Etc.

  The control target unit 11 includes one or a plurality of control target devices. The device to be controlled is a device for changing the environment inside the facility according to the purpose. Examples of the control target device include a skylight ventilator and a ventilation fan for adjusting the temperature, humidity, and air volume in the facility, and a light-shielding curtain for adjusting the amount of solar radiation. The control target device is controlled by a control device described later.

  The control unit 12 has one or a plurality of control devices. One or more control target devices to be controlled are assigned to the control device. In the present embodiment, it is assumed that one control apparatus controls one control target apparatus. In the present embodiment, there are a plurality of control methods (hereinafter referred to as control modes) of the control device. When each control device does not acquire instruction information to be described later, each control device acquires environment information from one or more sensors, and controls the control target device based on the obtained environment information. Control in which the control device reads the sensor value and determines an appropriate operation of the control target device based on the sensor value is called autonomous control. This autonomous control mode is called an autonomous control mode. Examples of the control device include a skylight control device and a ventilation fan control device. For example, when performing skylight control, the skylight control device opens and closes the skylight according to any one of the temperature, humidity, wind direction, and wind speed inside and outside the facility read from the sensor.

  In addition to the autonomous control described above, each control device controls the device to be controlled by composite control, manual control, and remote control. Here, since autonomous control and composite control are not caused by input from the user, they are collectively referred to as automatic control. In addition, manual control is physical control that is manually applied to the control target device. However, when the control target device is manually controlled, the manual control and the degree of control are controlled by the control target device. It can be detected by the control device.

  Each control device controls the device to be controlled with a control amount indicating the degree of control. In the present embodiment, the control amount is represented by an integer from 1 to 100, and 100 is set when the control target device is operated to the maximum, and 0 is set when the control target device is stopped. For example, the skylight control device controls the skylight with 0 as the control amount when the skylight is completely closed, 50 as the control amount when the skylight is half open, and 100 as the control amount when the skylight is fully opened. To do. Further, for example, the ventilating fan control device controls the ventilating fan with a control amount corresponding to the magnitude of the rotation speed of the fan per unit time. The control amount for the maximum number of revolutions per unit time is 100, and the control amount for stopping the ventilation fan is 0. Although the control amount is an integer from 1 to 100 in this embodiment, the present invention is not limited to this, and the numerical range of the control amount may be different for each control device. There may be a control device to control.

  As shown in FIG. 3, the management unit 13 includes a communication unit 130, an operation management unit 131, and a storage unit 132 that are connected to each other to exchange information. In FIG. 3, for example, a line with an arrow indicating that information is output from the communication unit 130 to the operation management unit 131 is described, but information may be output from the operation management unit 131 to the communication unit 130. There may be. The direction of information exchange shown in FIG. 3 is merely an example.

  The information communication unit 130 exchanges information with the server 2 through the Internet. The exchanged information includes instruction information transmitted from the server 2 to the management unit 13, and operation information, environment information, accumulated operation information, and accumulated environment information transmitted from the management unit 13 to the server 2. .

  The instruction information is information including contents for designating a control amount of each control device and instructing each control device to perform control with the designated control amount. The instruction information includes composite control instruction information and remote instruction information. The composite control instruction information is information of contents instructing each control device to perform control with the control amount derived by the server 2 based on the received environment information or the like. The remote instruction information is instruction information issued based on an input to the remote operation device 3. In order to distinguish between the composite control instruction information and the remote instruction information, for example, a flag is provided in these information.

  The operation information is information indicating the control mode and the control amount of each control device or devices at an arbitrary time. Note that the operation information in this embodiment is information indicating the control mode and the control amount of one or more installed control devices.

  The accumulated environment information is accumulated environment information for a predetermined time. The accumulated operation information is accumulated operation information for a predetermined time.

  The communication unit 130 outputs the received instruction information to the operation management unit 131. The operation management unit 131 refers to the acquired instruction information, determines whether it is composite control instruction information or remote instruction information, and stores the result in the operation database 133 of the storage unit 132. At this time, if the received instruction information is composite control instruction information, it is stored as a composite control mode, and if it is remote instruction information, it is stored as a remote control mode. Further, the control amount of each control device in the instruction information is stored in the operation database 133.

  The operation management unit 131 also outputs an instruction to each control device so that each control device performs control with a control amount in accordance with the instruction information. The control device that has received the instruction controls the device to be controlled based on the content of the instruction.

  Control based on composite control instruction information by the control device is referred to as composite control. The control mode of composite control is referred to as composite control mode. Control based on remote instruction information by the control device is referred to as remote control. The remote control mode is referred to as a remote control mode.

  The control based on the composite control instruction information or the remote instruction information may be performed by the entire control apparatus, a combination of a plurality of arbitrary control apparatuses, or a single control apparatus. Which control device performs control based on the instruction information may be determined in advance by an apparatus in the system, or may be specified in the instruction information.

  When the control device that is the target of the instruction in the instruction information is a plurality of control devices, for example, “initial value” is set as the control mode of the control device that controls the control target device that does not need to be operated. Whether this “initial value” instructs autonomous control or means to stop the device to be controlled is set in each control device or the operation management unit 131.

  When the control device that is the target of the instruction in the instruction information is a part of the control devices, the other control devices may perform autonomous control or stop control.

  When the communication state between the server 2 and the local node 1 is interrupted during the composite control mode or the remote control mode, the operation management unit 131 waits for a certain period of time. If no instruction information is received during the predetermined time, the operation management unit 131 outputs an instruction to shift to the autonomous control mode to the control unit 12. Upon receiving an instruction from the operation management unit 131, the control unit 12 shifts to the autonomous control mode. As the control unit 12 shifts to the autonomous control mode, the operation management unit 131 indicates in the operation database 133 the time at which the shift is performed and the control mode, that is, the autonomous control mode. Remember every time. When performing the autonomous control, the control unit 12 notifies the operation management unit 131 of the control amount every five minutes, for example, and the operation management unit 131 stores the notified time and control amount in the operation database 133 each time. Remember.

  Further, when there is manual control, the control unit 12 senses it through the sensor group 10 to obtain a control amount, and notifies the operation management unit 131 of the sensing result and the control amount. The operation management unit 131 stores the manual control in the operation database 133 and the control amount at that time.

  As described above, the storage unit 132 acquires operation information that is information related to the control mode and the control amount at each time from the operation management unit 131. Then, the operation information is accumulated and stored as accumulated operation information. In addition, the storage unit 132 acquires environmental information at each time from the sensor group 10, accumulates the environmental information in the environmental database 134, and holds the accumulated environmental information.

  4 and 5 are examples of storage environment information and storage operation information held by the storage unit 132, respectively. The storage environment information according to the example shown in FIG. 4 is in the form of a table in which each time every five minutes is associated with the sensor value obtained at each time. The storage operation information according to the example shown in FIG. 5 is in the form of a table in which the time associated with each time in the above-described storage environment information is associated with the operation information at each time. In FIG. 4, only the in-facility temperature and the out-of-facility temperature are shown as sensor values. However, what is stored as accumulated environment information includes in-facility humidity and the like, and the installed sensors. The value whose value can be detected is included. The same applies to the case of FIG. 5, and what is held as the accumulation operation information includes the control mode and the control amount of each installed control device.

  As shown in FIG. 3, the communication unit 130 reads the current environment information from the storage unit 132 and transmits it to the server 2. Alternatively, although the connection between the communication unit 130 and the sensor group 10 is not illustrated, the communication unit 130 may acquire environmental information from the sensor group 10 and transmit it to the server 2. As will be described later, the instruction information generation unit 23 of the server 2 generates composite control instruction information using the transmitted environment information.

  The server 2 receives the environment information and operation information received from the local node 1, accumulates them, and stores them in the format shown in FIGS. 4 and 5, for example. In addition, when communication between the server 2 and the local node 1 is interrupted for a certain time, after the communication state is restored, the local node 1 with respect to the server 2 receives all or part of the storage environment information and the storage operation information. Send.

  The storage unit 132 holds the storage environment information and the storage operation information in case the communication with the server 2 is interrupted. However, the storage unit 132 starts storing the environment information and the operation information after the communication is stopped. Also good. The storage unit 132 may delete the stored storage environment information and storage operation information after transmitting the storage environment information and storage operation information to the server 2.

  The storage environment information shown in FIG. 4 and the example of the storage operation information shown in FIG. 5 are each in a table format, but may be in other formats.

  In the present embodiment, the control unit 12 is described as being separate from the management unit 13 and the control target unit 11, but the control unit 12 is included in the management unit 13 and deployed below the operation management unit 131. May be. Each control device may be integrated with each control target device. One control device may control a plurality of control target devices.

  FIG. 6 is a functional block diagram of the server 2 according to the present embodiment. As shown in FIG. 6, the server 2 includes a communication unit 20, a storage unit 21, a display information generation unit 22, and an instruction information generation unit 23. The communication unit 20, the storage unit 21, and the display information generation unit 22 are connected to each other for exchanging information. The communication unit 20, the storage unit 21, and the instruction information generation unit 23 are connected to each other for exchanging information. The display information generation unit 22 and the instruction information generation unit 23 may be connected or may not be connected.

  As described above, the communication unit 20 transmits and receives instruction information, operation information, environment information, and the like to and from the local node 1. Further, the communication unit 20 transmits display information described later to the remote operation device 3 and receives remote instruction information or desired environment information from the remote operation device 3. The desired environment information is information indicating an environmental state desired by the user who operates the remote control device 3, and includes information such as temperature and humidity.

  The storage unit 21 stores the accumulated environment information in the environment database 210 and the accumulated operation information in the operation database 211. The storage unit 21 stores the environment information and the operation information received via the communication unit 20 in the environment database 210 and the operation database 211, respectively.

  The display information generation unit 22 has a control state display program. The display information generation unit 22 executes the control state display program, reads the storage environment information and the storage operation information from the storage unit 21, and generates display information based on them. The display information is composed of HTML (HyperText Markup Language) or the like. The display information is processed by the remote operation device 3 that has received the display information, and an image to be described later is displayed on the display unit 33 of the remote operation device 3. The processing of the display information generation unit 22 will be described later.

  In order to optimize the environmental state in the facility, the instruction information generation unit 23 obtains a control amount of each control device based on the received current environment information, and generates composite control instruction information. In addition, the instruction information generation unit 23 acquires the desired environment information received by the communication unit 20, and generates remote instruction information for setting the environmental state in the facility to the environmental state desired by the user.

  The instruction information changes depending on the environment inside and outside the facility, the performance of the control device, and the like. Therefore, it is assumed that a program for generating instruction information, an operation method of the instruction information generating unit 23, and the like are obtained through experiments.

  The instruction information obtained by the instruction information generation 23 is transmitted to the local node 1 by the communication unit 20.

  FIG. 7 is a block diagram showing an example of the configuration of the remote control device 3. The remote operation device 3 is, for example, a smartphone, a PC (Personal Computer), or a tablet terminal, and includes an input unit 30, a communication unit 31, a display processing unit 32, and a display unit 33. As shown in FIG. 7, in order to exchange information with each other, the input unit 30 and the communication unit 31 are connected to each other, the communication unit 31 and the display processing unit 32 are connected to each other, and the display processing unit 32 and the display unit 33 are connected to each other. It is connected. In addition, there may be connection of each part other than shown in FIG.

  The input unit 30 is a keyboard, a mouse, a touch panel, or the like, and the user inputs remote instruction information, desired environment information, and the like to the remote operation device 3 via the input unit 30.

  The communication unit 31 transmits and receives remote instruction information, desired environment information, display information, and the like with the communication unit 20 of the server 2 via the Internet.

  The display processing unit 32 includes an image browser and performs processing for displaying an image corresponding to the display information received by the communication unit 31 on the display unit 33. The display processing unit 32 may realize a function corresponding to the display information generation unit 22 described above. In this case, the display processing unit 32 holds the control state display program in advance, is acquired through the Internet, or is readable from a portable storage medium. Then, the environment information and operation information in the time range desired to be displayed may be acquired from the server 2, and the control state display program may be executed to generate an image.

  The display unit 33 is, for example, a liquid crystal display or a plasma display, and outputs display contents based on display information.

  FIG. 8 shows an example of an image showing a control history displayed on the display unit 33 based on the display information. The line graph in the middle of the image 4 shown in FIG. 8 is displayed based on display information generated based on the accumulated environment information stored in the environment database 210 of the storage unit 21. In this figure, a line graph is shown, but a bar graph, a pie chart, or the like may be used.

  This line graph shows the transition of the in-facility temperature during a predetermined time. For example, in FIG. 8, the predetermined time can be selected from 1 hour, 3 hours, 6 hours, 12 hours, and 24 hours as shown in the upper right of the line graph. In addition to information related to the temperature in the facility, the change in humidity in the facility can be changed by touching the screen portion of “humidity” in the area displayed as “environment in the facility” in the upper part of the image 4, for example. Indicated. In addition, by operating the scroll bar on the right side of the line graph, changes in the humidity inside the facility, the amount of carbon dioxide, the amount of integrated solar radiation, and the like are shown.

  The lower graph of the image 4 (hereinafter also referred to as a control graph) indicates in which control mode and control amount each control target apparatus is controlled. In the image 4, the area where the above-mentioned line graph is displayed and the area where this control graph is displayed are called a display column 41 and a display column 42, respectively.

  The middle line graph and lower control graph of image 4 each have the X axis as the time axis, and each time axis corresponds to the position on the screen where the X coordinate of the display unit 33 is the same at the same time. It is attached. In the control graph, for each control target device, a plurality of bars 40 perpendicular to the time axis are arranged along the time axis.

  Here, the bar is a region having an area larger than 0 in the image (hereinafter, this region is referred to as a display region), and a color different from the background color is applied in this region. Say what you are.

  In this embodiment, this display area is assumed to be a rectangle with the X-axis method being the short side direction and the Y-axis direction being the long side direction. Further, the bar 40 represents the control mode and the control amount by the color arrangement in the display area.

  Specifically, one bar 40 indicates a control mode and a control amount of a certain control device at a certain time. In order to show the control mode, the bar 40 is colored differently for each control mode. In order to show each color, different hatching is given to each color in FIG. For example, the bar 40A is provided with a plurality of parallel lines that rise to the right. This hatching corresponds to blue in the actual image 4 in the example of the present embodiment. The blue bar indicates that the control target device is controlled in the composite control mode.

  The other hatching, the other colors, and the other control modes are associated in the same manner. For example, the bar 40 in the case of the autonomous control mode is hatched with a plurality of oblique lines that are parallel to the lower right in FIG. 8, but is displayed in green on the screen in the example of the present embodiment. In addition to indicating the autonomous control mode, the green bar 40 is used when the control target device is operating in the autonomous control mode and the control is stopped while the control amount is fixed because the sensor value does not change. Shall also be indicated.

  In FIG. 8, the bar 40 in the case of manual control is hatched by a plurality of parallel lines in the Y direction, but is displayed in yellow on the screen in an example of the present embodiment. The bar 40 representing the remote control mode is hatched with a plurality of parallel lines in the X direction in FIG. 8, but is displayed in red on the screen in an example of the present embodiment.

These color combinations are merely examples, and other color combinations may be used.
In FIG. 8, the bar 40 </ b> A is composed of a lower portion having a high density of hatched lines and an upper portion having a lower density of hatched lines. On the screen, this upper part is the same color as the lower part and lighter than the lower part. That is, the upper part and the lower part are displayed on the display unit 33 in light blue and dark blue, respectively, in the case of the bar 40A. The height of the lower part in the Y direction indicates the control amount. Since the lower part of the bar 40A occupies half of the entire bar 40A, it indicates that control of about 50 control amounts among the control amounts of 1 to 100 was performed on the west skylight. . Similarly, in the case of autonomous control, remote control, and manual control, the height of the lower portion in the Y direction indicates the control amount.

  Thus, in an example of the present embodiment, the inside of the bar 40 is set as a display area, and the control mode is distinguished by the difference in color of the display area. The control amount is represented by the range occupied by the upper part and the lower part having different shades in the display area. Note that the amount of control used is not limited to the height of the lower part. Instead of using the lower part, for example, the range that the pattern occupies may be used, or the numerical value of the control amount is displayed in the bar. It may be displayed.

  Now, since the three bars 40B in FIG. 8 have no lower part, from 9:40 to 9:45, the west skylight was controlled with a control amount of 0, that is, completely closed. Can be guessed.

  However, the bar from 9:30 to 9:45 on the west skylight indicates the composite control mode, but the control amount does not change. It can also be seen that at 9:45, the control of the west skylight has been switched to autonomous control. Therefore, it can be recognized that the instruction information to the local node 1 has been interrupted from the server 2 for a certain period of time until 9:45.

  Here, the color of the bar 40 during a certain period of time when communication is interrupted is the color representing the control mode immediately before communication is interrupted. Here, the display information generation unit 22 uses the information immediately before the communication is interrupted because the storage unit 21 does not have the environment information and the operation information for a certain period of time. However, the bar 40 for a certain period of time when communication is interrupted may be displayed in a color that can be distinguished from the color representing the control mode. Further, the bar 40 may be distinguished by adding some mark. In these cases, since the operation information for a predetermined time does not exist in the storage unit 21, the display information generation unit 22 displays the display information for displaying the bar 40 for the predetermined time as the operation information or the default value received immediately before. And so on.

  When the server 2 receives from the local node 1 the operation information for the predetermined time that does not exist in the storage unit 21 after the recovery of the communication state, the accumulated operation information or the like in the storage unit 21 is stored for the predetermined time. It is supplemented or updated by operation information or the like. The case where it is updated is a case where, for example, a NUL value or the like is set in the portion corresponding to the predetermined time in the storage unit 21 during the predetermined time.

  At 10:40, the bar 40D is again blue, and it can be recognized that the local node 1 has received the composite control instruction information.

  As shown in bar 40E, the west side window is controlled by the remote control mode at 13:30, and after being opened by about half, in the autonomous control mode, as shown in bar 40F. It can be seen that about half of the opening is maintained.

  As described above, according to the example of the present embodiment, it is possible to display different control modes.

  FIG. 9 shows an example of an image displayed when the “device state” portion is operated with a tap or the like on the screen on which the image 4 shown in FIG. 8 is displayed. In the image 5 according to this example, a small window is newly displayed near the “device state”. In this small window, a list of devices to be controlled that are currently installed in or can be installed in the local node 1 is displayed as icons. In these icons in FIG. 9, the type of the control target device is displayed as characters, but the type of the control target device may be displayed as a picture other than characters.

  Here, in the small window, the “skylight ventilation” icon is not hatched, but the “ceiling fan” icon is hatched. This indicates that the facility has a skylight, which is a skylight ventilation device, but no ceiling fan. However, an icon is provided in the image 5 to indicate that a ceiling fan can be provided in the facility in the future. Alternatively, the ceiling fan is controlled only by manual control, and since it is not necessary to monitor the control mode, it may be set such that operation information is not transmitted. In the actual image 5, it is assumed that such an icon indicating a control target device is darkly displayed, gray-colored, or the like so that it can be easily distinguished from the icon of the control target device included in the facility.

  Now, by operating an icon such as “skylight ventilation” with a tap or the like, the control mode and the control amount of the control target device indicated by the operated icon may be displayed.

  FIG. 10 is a diagram illustrating an example of an image displayed on the display unit 33 based on the display information. In the image 6 shown in FIG. 10, each sensor value indicating the environmental state inside and outside the facility and the state of each control target device are shown.

  A plurality of areas in which combinations of letters and numbers are displayed, such as a combination of “in-facility temperature” and “16.4 ° C.”, are arranged from the center of the image 6 to the left side. It is for showing.

  The table on the right side of the image 6 is for indicating the type, device name, and control amount of each control target device at the date and time indicated in the column “Reception date and time”. For example, it can be recognized from FIG. 10 that there are two skylight ventilators, the first system and the second system, and that the first system skylight ventilator is a west skylight. And it is recognizable that the skylight ventilator of the first system is controlled by the control amount 0 at the time of 14: 2 on the 20th year of YY month ZZ.

  FIG. 11 shows an example of an image displayed when “remote operation” is operated with a tap or the like on the screen on which the image 6 of FIG. 10 is displayed. In the image 7 shown in FIG. 11, a list of control target devices that can be remotely operated is displayed as icons inside the small window displayed in the vicinity of the area where the characters “remote operation” are displayed. The hatched icons are the same as those described with reference to FIG. Here, for example, when the “skylight ventilation” icon is operated with a tap or the like on the screen, an image (not shown) for determining the control amount related to the control of the skylight is displayed, and the user uses the control amount of the desired control amount. Input can be made. This input information is included in the remote instruction information and transmitted to the server 2.

  Further, the user may be allowed to input a desired value in an area indicating each sensor value, which is arranged on the left side from the center of the image 6 shown in FIG. Information input in this way is included in the desired environment information and transmitted to the server 2.

  FIG. 12 is a flowchart for explaining a process in which the server 2 generates display information. The communication unit 20 receives a display request via the Internet by input to the input unit 30 of the remote control device 3, for example, input of a URL (Uniform Resource Locator) or tap of a screen. The display request is output from the communication unit 20 to the display information generation unit 22 (S101). Note that the communication unit 20 refers to the transmitted information and determines the output destination.

  The display information generation unit 22 determines whether the acquired display request includes designation of a time range desired for display. If no time range is specified, the default time range is specified. Then, the environment information and the operation information in the designated time range are read from the environment database 210 and the operation database 211 of the storage unit 21 (S102). Subsequently, based on the read environment information and operation information, display information for generating the image 4 shown in FIG. 8 and the like on the display unit 33 is generated using a known image data processing method (S103).

  In this step S103, display information is generated so that the X-coordinates at the same time on the time axes of the display column 41 and the display column 42 are the same. In the display information generation process for the bar 40 portion of the display field 42, for example, the following process is performed. The display information generation unit 22 refers to the control mode and the control amount of the control device having a certain time in the operation information. From the control mode, a color tendency such as blue or red is selected. Then, the range of the dark color portion in the display area of the bar 40 is obtained using the control amount, and the balance of the shade of color in the bar 40 is determined. Information relating to the color tendency selected in this way and the balance of color shading is generated.

  In subsequent step S104, the display information generation unit 22 instructs the communication unit 20 to transmit the display information to the transmission source of the display request (S104).

  In the remote operation device 3, the display processing unit 32 that has acquired the display information performs known image processing, and the display unit 33 displays the image 4 or the like corresponding to the display information.

  Here, the control status display program is assumed to be included in the display information generation unit. However, the control status display program may be acquired via the Internet or the like, or may be stored in and read from a portable storage medium.

  The remote operation device 3 may perform processing corresponding to the display information generation unit 22 instead of the server 2. In this case, the remote control device 3 has a control state display program. If the processing by the remote control device 3 in this case is described with reference to FIG. 12, first, the processing of step S101 and step S104 is unnecessary. The remote control device 3 acquires environmental information and the like from the storage unit 21 of the server 2 via the communication unit 31 and the like (S102). The display processing unit 32 performs processing for displaying an image on the display unit 33 by executing the control state display program, instead of the display information generation processing in step S103. However, this control state display program is not for generating HTML or the like but for displaying the image 4 or the like on the display unit 33 of the remote operation device 3.
