The device control unit 116 acquires the control information corresponding to the operation information stored in the operation information storage unit 134 from the control information stored in the control information storage unit 137. Then, the device control unit 116 controls the operating state of the ventilation device 2 based on the acquired control information. Specifically, the device control unit 116 controls the operating state of the ventilation device 2 by transmitting the acquired control information to the ventilation device 2.

Next, the operation of the control system according to the present embodiment will be described with reference to FIG. Here, it will be described that the ventilation device 2 transmits the operation state information indicating the operation state of the own device to the control device 1 each time the operation state notification time arrives at a preset cycle. Further, when a plurality of ventilation devices 2 exist, the operation status notification timings of the plurality of ventilation devices 2 may be synchronized or asynchronous. First, when the preset operation state notification time arrives, the operation state information indicating the operation state of the ventilation device 2 is transmitted from the ventilation device 2 to the control device 1 (step S1). On the other hand, when the control device 1 receives the operation state information, the control device 1 acquires the building information from the building information storage unit 132 (step S2). Next, the control device 1 sets the display mode of the arrow image corresponding to the ventilation device 2 based on the operation state information and the building information received from the ventilation device 2 (step S3). Subsequently, the control device 1 generates construction information including the display mode information indicating the set display mode and the acquired building information (step S4). After that, the generated construction information is transmitted from the control device 1 to the terminal device 3 (step S5). On the other hand, when the terminal device 3 receives the construction information, the terminal device 3 refers to the image information stored in the image storage unit 332 and constructs the operation screen image based on the received construction information (step S6). Next, the terminal device 3 causes the display unit 304 to display the constructed operation screen image (step S7).

Here, it is assumed that the user performs a preset operation for instructing the operating state of the ventilation device 2 while the operation screen image is displayed on the display unit 304 of the terminal device 3. In this case, the terminal device 3 accepts the operation by the user. Then, the terminal device 3 generates operation information indicating the content of the operation performed by the user on the terminal device 3 (step S8). Subsequently, the generated operation information is transmitted from the terminal device 3 to the control device 1 (step S9). On the other hand, when the control device 1 receives the operation information from the terminal device 3, the control device 1 refers to the control information stored in the control information storage unit 137 and generates the control information to be transmitted to the ventilation device 2 based on the received operation information. (Step S10). After that, the generated control information is transmitted from the control device 1 to the ventilation device 2 (step S11). On the other hand, when the ventilation device 2 receives the control information from the control device 1, the ventilation device 2 changes the operating state of its own device based on the received control information (step S12). Next, when the ventilation device 2 completes the change of the operating state of its own device, the completion notification information notifying that fact is transmitted from the ventilation device 2 to the control device 1 (step S13).

Next, the ventilation device control process executed by the control device 1 will be described with reference to FIGS. 11 and 12. The ventilation device control process is started when the power is turned on to the control device 1. Further, it is assumed that the arrival cycle of the operation state notification time is set to a time between 500 msec and 1 sec. First, the state acquisition unit 111 acquires the operation state information indicating the operation state of the ventilation device 2 from the ventilation device 2 (step S101). Here, the state acquisition unit 111 stores the acquired operation state information in the operation state storage unit 133. Next, the building information acquisition unit 112 acquires the building information of the building in which the ventilation device 2 is installed from the building information storage unit 132 (step S102). Subsequently, the display mode setting unit 113 sets the display mode of the arrow image based on the operation state information stored in the operation state storage unit 133 and the building information notified from the building information acquisition unit 112 (step S103). ). After that, the display mode setting unit 113 generates construction information for constructing an operation screen image including the display mode information indicating the set display mode and the building information (step S104). Here, the display mode setting unit 113 stores the generated construction information in the construction information storage unit 131. Next, the construction information transmission unit 114 transmits the construction information stored in the construction information storage unit 131 to the terminal device 3 (step S105).

Subsequently, the operation information receiving unit 115 determines whether or not the operation information has been received from the terminal device 3 within the preset standby time (step S106). Here, the waiting time is set to, for example, 30 seconds. Here, if it is determined that the operation information receiving unit 115 does not receive the operation information within the standby time (step S106: No), the state acquisition unit 111 acquires the operation state information periodically transmitted from the ventilation device 2. (Step S108). At this time, the state acquisition unit 111 stores the acquired operation state information in the operation state storage unit 133. After that, the process of step S109 described later is executed.

On the other hand, when the operation information receiving unit 115 determines that the operation information has been received from the terminal device 3 within the above-mentioned standby time (step S106: Yes), the operation information receiving unit 115 stores the received operation information in the operation information storage unit 134. Then, the control information generation transmission process of generating the control information and transmitting it to the ventilation device 2 is executed (step S107).

Here, the details of the control information generation and transmission process will be described with reference to FIG. First, the device control unit 116 determines whether or not the operation information stored in the operation information storage unit 134 is related to the ventilation device 2 (step S301). Specifically, when the operation information includes the arrow image identification information, the device control unit 116 determines that the operation information is related to the ventilation device 2. Here, when the device control unit 116 determines that the operation information is not related to the ventilation device 2 (step S301: No), the device control unit 116 refers to the control information stored in the control information storage unit 137, and controls corresponding to the operation information. Information is generated (step S302). Next, the device control unit 116 transmits the generated control information to the ventilation device 2 (step S303). Subsequently, the state acquisition unit 111 acquires the operation state information periodically transmitted from the ventilation device 2 (step S304). At this time, the state acquisition unit 111 stores the acquired operation state information in the operation state storage unit 133. After that, the process of step S109 shown in FIG. 11 is executed.

Returning to FIG. 12, on the other hand, when the device control unit 116 determines that the operation information stored in the operation information storage unit 134 is related to the ventilation device 2 (step S301: Yes), the ventilation device 2 can be controlled. (Step S305). Specifically, the device control unit 116 can control the specified device when the device identification information is associated with the device image identification information of the specified device in the building information stored in the building information storage unit 132. Is determined to be. For example, the symbol image GA5 showing the ventilation device 2 arranged in the regions GA (R2B), GA (R2C), GA (R1C), and GA (R1A) in the operation screen image GAM1 shown in FIG. 7B is shown in FIG. 7A. Corresponds to the device image identification information ID (GA5). Further, the symbol image GA6 of the ventilation device (air conditioner) in the operation screen image GAM1 shown in FIG. 7B corresponds to the device image identification information ID (GA6) in FIG. 7A. In this case, since the device control unit 116 is assigned the device identification information "0", "1", and "2" to the device image identification information ID (GA5), the ventilation corresponding to the device image identification information ID (GA5). The device 2 determines that it can be controlled. On the other hand, the device control unit 116 determines that the air conditioner corresponding to the device image identification information ID (GA6) cannot be controlled because the device identification information corresponding to the device image identification information ID (GA6) is not assigned.

Here, when the device control unit 116 determines that the ventilation device 2 cannot be controlled (step S305: No), the warning information transmission unit 117 generates warning information and transmits it to the terminal device 3 (step S306). .. Next, the processes after step S304 described above are executed. On the other hand, when the device control unit 116 determines that the ventilation device 2 can be controlled (step S305: Yes), the device control unit 116 refers to the control information stored in the control information storage unit 137 and generates control information corresponding to the operation information. (Step S307). Subsequently, the device control unit 116 transmits the generated control information to the ventilation device 2 (step S308). At this time, the ventilation device 2 updates the operating state of its own device based on the control information received from the control device 1. Then, when the update of the operating state is completed, the ventilation device 2 generates completion notification information for notifying that fact and transmits it to the control device 1.

After that, the device control unit 116 determines whether or not the completion notification information has been received from the ventilation device 2 within the preset standby time (step S309). This waiting time is set, for example, from 1 sec to 10 sec. Here, if it is determined that the device control unit 116 has not received the completion notification information from the ventilation device 2 within the above-mentioned standby time (step S309: No), the process of step S312 described later is executed. On the other hand, when it is determined by the device control unit 116 that the completion notification information has been received from the ventilation device 2 (step S309: Yes), the state acquisition unit 111 acquires the operation state information periodically transmitted from the ventilation device 2. (Step S310). At this time, the state acquisition unit 111 stores the acquired operation state information in the operation state storage unit 133. Next, the device control unit 116 determines whether or not the operating state indicated by the operating state information stored in the operating state storage unit 133 and the operating state corresponding to the control information match (step S311). Here, it is assumed that the device control unit 116 determines that the operation state indicated by the operation state information stored in the operation state storage unit 133 and the operation state corresponding to the control information do not match (step S311: No). .. In this case, the warning information transmission unit 117 generates warning information and transmits it to the terminal device 3 (step S312). On the other hand, when the device control unit 116 determines that the operation state indicated by the operation state information stored in the operation state storage unit 133 and the operation state corresponding to the control information match (step S311: Yes), it is as it is. The process of step S109 shown in FIG. 11 is executed.

In step S109 of FIG. 11, the building information acquisition unit 112 and the display mode setting unit 113 determine whether or not the operation state information stored in the operation state storage unit 133 has been updated (step S109). When the building information acquisition unit 112 and the display mode setting unit 113 determine that the operation state information stored in the operation state storage unit 133 has been updated (step S109: Yes), the process of step S102 is executed again. On the other hand, it is assumed that the building information acquisition unit 112 and the display mode setting unit 113 determine that the operation state information stored in the operation state storage unit 133 has not been updated (step S109: No). In this case, the operation information receiving unit 115 determines whether or not the end command information for terminating the ventilation device control process has been input (step S110). Here, the end command information is input, for example, when the user turns off the power of the control device 1. When the operation information receiving unit 115 determines that the end command information has not been input (step S110: No), the process of step S106 is executed again. On the other hand, when the operation information receiving unit 115 determines that the end command information has been input (step S110: Yes), the ventilation device control process ends.

Next, the operation screen image display process executed by the terminal device 3 according to the present embodiment will be described with reference to FIG. The operation screen image display process is started when the application for displaying the operation screen image is started after the power is turned on to the terminal device 3. First, the construction information receiving unit 311 determines whether or not the construction information transmitted from the control device 1 has been received (step S201). When the construction information receiving unit 311 determines that the construction information transmitted from the control device 1 has not been received (step S201: No), the process of step S207 described later is executed.

On the other hand, when the construction information receiving unit 311 receives the construction information transmitted from the control device 1 (step S201: Yes), the construction information receiving unit 311 stores the received construction information in the construction information storage unit 331. Next, the screen construction unit 312 acquires the building image information stored in the image storage unit 332 based on the building image type information included in the construction information stored in the construction information storage unit 331, and the acquired building image. Information is written in the operation screen storage unit 323 (step S202). Subsequently, the screen construction unit 312 acquires and acquires the symbol image information of the device stored in the image storage unit 332 based on the device image image identification information included in the construction information stored in the construction information storage unit 331. The symbol image information is written in the operation screen storage unit 323 (step S203).

After that, the screen construction unit 312 uses arrows based on the arrow image identification information, the position information of the arrow image, the size information of the arrow image, and the attitude information of the arrow image included in the construction information stored in the construction information storage unit 331. The image is molded (step S204). Here, the screen construction unit 312 includes basic size information included in the contour vector information stored in the image storage unit 332 and size information of the arrow image included in the construction information for the image indicated by the arrow image identification information described above. , To identify how to scale the arrow image. At this time, the screen construction unit 312 specifies a scaling method of the arrow image so that the length of the arrow image in the longitudinal direction is expanded and contracted so that the size of the head of the arrow and the width of the arrow are constant. Then, the screen construction unit 312 shapes the arrow image by scaling the arrow image from the basic size by the specified scaling method.

Next, the screen construction unit 312 writes the arrow image information indicating the arrow image after molding into the operation screen storage unit 323 (step S205). As a result, the operation screen image information including the building image information, the symbol image information of the device, and the arrow image information is stored in the operation screen storage unit 323. Here, when the screen construction unit 312 completes writing the building image information, the symbol image information of the device, and the arrow image information to the operation screen storage unit 323, the screen construction unit 312 notifies the display control unit 313 of the writing completion notification. Subsequently, when the writing completion notification is input, the display control unit 313 causes the display unit 304 to display the operation screen image information stored in the operation screen storage unit 323 (step S206).

After that, the construction information receiving unit 311 determines whether or not the end command information for ending the operation screen image display process has been input (step S207). Here, the end command information is input when, for example, the user performs an operation for terminating the operation screen image display process on the input unit 305. When the construction information receiving unit 311 determines that the end command information has not been input (step S207: No), the process of step S201 is executed again. On the other hand, when the construction information receiving unit 311 determines that the end command information has been input (step S207: Yes), the operation screen image display process ends.

Next, an example of the user's operation in the terminal device 3 according to the present embodiment and the state transition of the operation screen image GAM1 displayed on the display unit 304 by the operation will be described. It is assumed that the ventilation device 2 is installed in the building H as shown in FIG. 1B, and all of the ventilation devices 2 are stopped. In this case, the display unit 304 displays the operation screen image GAM1 including the building image GA8 showing a schematic view of the building as shown in FIG. 14A. In FIG. 14A, it is assumed that the transparent touch pad, which is the input unit 305, is arranged so as to overlap the display unit 304. Here, in the building H shown in FIG. 1B, the path of the airflow generated between the room R1C in the building H and the room R1B separated via the room R1A reaches the room R1B from the room R1C without passing through the room R1A. Suppose you are. In this case, as shown in FIG. 14A, the arrow image GA11 showing the path of the airflow from the room R1C to the room R1B has a base end portion overlapping with the region GA (R1C) corresponding to the room R1C in the building image GA8 and the tip end. The portion has a shape that overlaps with the region GA (R1B) corresponding to the room R1B and does not overlap with the region GA (R1A) corresponding to the room R1A.

Then, with the operation screen image GAM1 shown in FIG. 14A displayed on the display unit 304, the user touches the portion of the touch pad corresponding to the arrow image GA12 with the finger F1 and drags or swipes in the direction indicated by the arrow AR1. When the operation is performed, the operation information indicating the operation content is transmitted from the terminal device 3 to the control device 1. Further, the drag operation or swipe operation in the direction indicated by the arrow AR1 is a drag operation performed from the areas GA (R2B) and GA (R2C) corresponding to the rooms R2B and R2C toward the outdoor area of the building corresponding to the outside of the building H. Or it can be called a swipe operation. In this case, the rooms R2B and R2C correspond to the eighth room, and the regions GA (R2B) and GA (R2C) in the building image GA8 correspond to the eighth region. The same applies to the arrow image GA11, and when a drag operation or a swipe operation is performed from the area GA (R1C) corresponding to the room R1C to the area GA (R1B) corresponding to the room R1B, the operation content is the same. The operation information indicating the above is transmitted from the terminal device 3 to the control device 1. In this case, the rooms R1C and R1B correspond to the 8th room and the 9th room, respectively, and the regions GA (R1C) and GA (R1B) in the building image GA8 correspond to the 8th region and the 9th region, respectively. do. On the other hand, when the control device 1 receives the operation information, the control device 1 operates the ventilation device 2 corresponding to the areas GA (R2B) and GA (R2C) in the operation screen image GAM 1, that is, the ventilation device 2 installed in the room R2B. Control information is generated and transmitted to the ventilation device 2. As a result, the ventilation device 2 installed in the room R2B starts operation. After that, when the operation state information is transmitted from the ventilation device 2 that has started the operation to the control device 1, the control device 1 generates new construction information based on the operation state information. Then, the control device 1 transmits the generated new construction information to the terminal device 3. On the other hand, when the terminal device 3 receives the new construction information, the terminal device 3 newly constructs an operation screen image including the arrow image GA13 of FIG. 6 based on the received construction information, and the operation screen storage unit 323 stores the operation screen image. The operation screen image information including the arrow image GA12 of FIG. 6 is updated with the newly constructed operation screen image information. As a result, the display mode of the arrow image GA12 shown in FIG. 14A changes to the arrow image GA13 as shown in FIG. 14B.

Further, the ventilation device 2 installed in the room R1A of the building H shown in FIG. 1B is a first-class ventilation fan that generates an air flow flowing from the room R1A to the outside of the building H or an air flow flowing from the outside of the building H to the room R1A. And. In this case, the symbol image corresponding to the ventilation device 2 installed in the room R1A includes two arrow images that are parallel to each other and point in opposite directions, as shown in the symbol image GA14 shown in FIG. 14A. It has become.

Further, in a state where all of the ventilation devices 2 installed in the building H are stopped, the operation screen image GAM2 including the building image GA9 showing the floor plan of the building as shown in FIG. 15A is displayed on the display unit 304. In some cases. In this case, with the operation screen image GAM2 shown in FIG. 15A displayed on the display unit 304, the user touches the portion of the touch pad corresponding to the arrow image GA12 with the finger F1 and drags or drags in the direction indicated by the arrow AR2. When the swipe operation is performed, the operation information indicating the operation content is transmitted from the terminal device 3 to the control device 1. On the other hand, when the control device 1 receives the operation information, the control device 1 generates control information for operating the ventilation device 2 corresponding to the arrow image GA12 in the operation screen image GAM2, that is, the ventilation device 2 installed in the rooms R2B and R2C. Then, it is transmitted to the ventilation device 2 installed in each of the rooms R2B and R2C. As a result, the ventilation device 2 installed in the rooms R2B and R2C starts to operate. After that, when the operation state information is transmitted from the ventilation device 2 that has started the operation to the control device 1, the control device 1 generates new construction information based on the operation state information. Then, the control device 1 transmits the generated new construction information to the terminal device 3. On the other hand, when the terminal device 3 receives the new construction information, the terminal device 3 newly constructs an operation screen image including the arrow image GA13 of FIG. 6 based on the received construction information, and the operation screen storage unit 323 stores the operation screen image. The operation screen image information including the arrow image GA12 of FIG. 6 is updated with the newly constructed operation screen image information. As a result, the display mode of the arrow image GA12 shown in FIG. 15A changes to the arrow image GA13 as shown in FIG. 15B.

Further, it is assumed that the ventilation device 2 is operating the ventilation device 2 installed in each of the rooms R2B and R2C shown in FIG. 1B and the ventilation device 2 installed in the room R1A. In this case, for example, the operation screen image GAM1 as shown in FIG. 16A is displayed on the display unit 304. Here, with the operation screen image GAM1 shown in FIG. 16A displayed on the display unit 304, the user touches the portion of the touch pad corresponding to the symbol image GA15 with the finger F1 and drags or drags in the direction indicated by the arrow AR3. When the swipe operation is performed, the operation information indicating the operation content is transmitted from the terminal device 3 to the control device 1. On the other hand, when the control device 1 receives the operation information, the control device 1 generates the ventilation device 2 corresponding to the symbol image GA15 in the operation screen image GAM 1, that is, the control information for stopping the ventilation device 2 installed in the room R1A. It transmits to the ventilation device 2 installed in the room R1A. Here, the control device 1 identifies the ventilation device 2 corresponding to the symbol image GA15 of the portion where the drag operation or the swipe operation is performed, based on the operation information. Then, when the control device 1 determines that the specified ventilation device is operating based on the operation state information acquired from the ventilation device 2, the direction in which the drag operation or the swipe operation is performed and the drag operation or the swipe operation are performed. When it is determined that the angle formed by the extension direction of the arrow image included in the symbol image GA15 of the portion is 60 degrees or more and 120 degrees or less, control information for stopping the specified ventilation device 2 is generated. As a result, the ventilation device 2 installed in the room R1A is stopped. After that, when the operation state information is transmitted from the stopped ventilation device 2 to the control device 1, the control device 1 generates new construction information based on the operation state information. Then, the control device 1 transmits the generated new construction information to the terminal device 3. On the other hand, when the terminal device 3 receives the new construction information, the terminal device 3 newly constructs an operation screen image including the symbol image GA14 of FIG. 6 based on the received construction information, and the operation screen storage unit 323 stores the operation screen image. The operation screen image information including the symbol image GA15 of FIG. 6 is updated with the newly constructed operation screen image information. As a result, the display mode of the symbol image GA15 shown in FIG. 16A changes to the symbol image GA14 as shown in FIG. 16B.

Further, while the operation screen image GAM1 as shown in FIG. 17A is displayed on the display unit 304, the user touches the portion of the touch pad corresponding to the arrow image GA13 with the finger F1 and drags it in the direction indicated by the arrow AR4. When an operation or a swipe operation is performed, operation information indicating the operation content is transmitted from the terminal device 3 to the control device 1. On the other hand, when the control device 1 receives the operation information, the control device 1 generates control information for stopping the ventilation device 2 corresponding to the arrow image GA13 in the operation screen image GAM1, that is, the ventilation device 2 installed in the rooms R2B and R2C. Then, it is transmitted to the ventilation device 2 installed in the rooms R2B and R2C. Here, the control device 1 identifies the ventilation device 2 corresponding to the arrow image GA13 of the portion where the drag operation or the swipe operation is performed based on the operation information. Then, when the control device 1 determines that the specified ventilation device is operating based on the operating state information acquired from the ventilation device 2, it generates control information for stopping the specified ventilation device 2. As a result, the ventilation device 2 installed in the rooms R2B and R2C is stopped. After that, when the operation state information is transmitted from the stopped ventilation device 2 to the control device 1, the control device 1 generates new construction information based on the operation state information. Then, the control device 1 transmits the generated new construction information to the terminal device 3. On the other hand, when the terminal device 3 receives the new construction information, the terminal device 3 newly constructs an operation screen image including the arrow image GA12 of FIG. 6 based on the received construction information, and the operation screen storage unit 323 stores the operation screen image. The operation screen image information including the arrow image GA13 in FIG. 6 is updated with the newly constructed operation screen image information. As a result, the display mode of the arrow image GA13 shown in FIG. 17A changes to the arrow image GA12 as shown in FIG. 17B.

Further, it is assumed that only the ventilation device 2 installed in the room R1A shown in FIG. 1B is operating. In this case, for example, the operation screen image GAM1 as shown in FIG. 18A is displayed on the display unit 304. In this case, when the user touches the part corresponding to the symbol image GA15 on the touch pad with two fingers F1 and F2 and slides each of them in the directions indicated by the arrows AR51 and AR52 in the directions away from each other, a so-called pinch-out operation is performed. , Operation information indicating the operation content is transmitted from the terminal device 3 to the control device 1. On the other hand, when the control device 1 receives the operation information, the control device 1 generates control information for increasing the air volume of the ventilation device 2 corresponding to the symbol image GA15 in the operation screen image GAM 1, that is, the ventilation device 2 installed in the room R1A. Then, it is transmitted to the ventilation device 2 installed in the room R1A. As a result, the air volume of the ventilation device 2 installed in the room R1A increases. After that, when the operating state information is transmitted from the ventilation device 2 with the increased air volume to the control device 1, the control device 1 generates new construction information based on the operating state information. Then, the control device 1 transmits the generated new construction information to the terminal device 3. On the other hand, when the terminal device 3 receives the new construction information, the terminal device 3 newly constructs the operation screen image information including the symbol image GA15 of FIG. 6 based on the received construction information. Here, the size of the symbol image GA 15 included in the newly constructed operation screen image is larger than the size of the symbol image GA 15 included in the operation screen image stored in advance by the operation screen storage unit 323. Then, the terminal device 3 updates the operation screen image information stored in advance by the operation screen storage unit 323 with the newly constructed operation screen image information. As a result, the size of the arrow image GA15 shown in FIG. 18A increases as the air volume increases, as shown in FIG. 18B.

Further, as shown in FIG. 19A, the user touches the portion of the touch pad corresponding to the symbol image GA15 with two fingers F1 and F2, and slides the portions in the directions indicated by the arrows AR61 and AR62 in the directions closer to each other. When a so-called pinch-in operation is performed, operation information indicating the operation content is transmitted from the terminal device 3 to the control device 1. On the other hand, when the control device 1 receives the operation information, it generates control information for reducing the air volume of the ventilation device 2 installed in the room R1A and transmits it to the ventilation device 2 installed in the room R1A. As a result, the air volume of the ventilation device 2 installed in the room R1A is reduced. After that, when the operating state information is transmitted from the ventilation device 2 in which the air volume is reduced to the control device 1, the control device 1 generates new construction information based on the operating state information. Then, the control device 1 transmits the generated new construction information to the terminal device 3. On the other hand, when the terminal device 3 receives the new construction information, the terminal device 3 newly constructs the operation screen image information including the symbol image GA15 of FIG. 6 based on the received construction information. Here, the size of the symbol image GA 15 included in the newly constructed operation screen image is smaller than the size of the symbol image GA 15 included in the operation screen image stored in advance by the operation screen storage unit 323. Then, the terminal device 3 updates the operation screen image information stored in advance by the operation screen storage unit 323 with the newly constructed operation screen image information. As a result, the size of the symbol image GA15 shown in FIG. 19A becomes smaller as shown in FIG. 19B as the air volume decreases. When the air volume setting of the ventilation device 2 corresponding to the symbol image GA15 is set to the minimum air volume, and the user performs a pinch-in operation on the portion corresponding to the symbol image GA15 on the touch pad, the control device 1 changes. The ventilation device 2 corresponding to the symbol image GA15 may be stopped.

As described above, according to the control device 1 according to the present embodiment, the display mode setting unit 113 sets the display mode of the symbol image and the arrow image of the device based on the operation state information and the building information. .. Further, the construction information transmission unit 114 transmits the construction information including the building information and the display mode information indicating the display mode to the terminal device 3.

Can be easily grasped. Therefore, the user can properly operate the ventilation device 2 based on the grasped operating state of the ventilation device 2 and the air flow inside the building.

Further, the display mode setting unit 113 according to the present embodiment is, for example, the airflow generation path and the airflow in which the airflow is generated among the airflow paths reaching the outside of the building H from the rooms of the two rooms R2B and R2C. When there is an airflow non-generation path in which Set to the arrow image GA12 of the broken line frame. As a result, the user can grasp the airflow generation path generated in the building H when the ventilation device 2 is operated while the ventilation device 2 is stopped. Therefore, since the user can grasp the airflow generation path when the ventilation device 2 is operated in advance before the operation, there is an advantage that unnecessary operation of the ventilation device 2 is suppressed.

Further, the symbol image showing the function of the first-class ventilation fan according to the present embodiment includes two arrow images that are parallel to each other and point in opposite directions, as shown in the symbol images GA14 and GA15 of FIG. .. As shown in the symbol images GA16, GA17, and GA18, the symbol images showing the function of the first-class ventilation fan with the heat exchange function are two arrow images and two arrow images that are parallel to each other and point in opposite directions.

As a result, the user can accurately determine whether the first-class ventilation fan is installed in the building H and whether or not the first-class ventilation fan installed in the building H has a heat exchange function. ..

Although the embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments. For example, instead of the arrow image GA11 showing the path of the airflow reaching the room R1B from the room R1C shown in FIG. 14A, for example, the arrow images GA2121, GA2122, and GA2123 having three broken line frames as shown in FIG. 20A are combined. May be adopted. Here, the tip portions of the arrow images GA2122 and GA2123 overlap with the arrow image GA2121. Here, for example, it is assumed that the arrow image GA2123 corresponds to the ventilation device 2 installed in the room R1B, and the arrow image GA2122 corresponds to the ventilation device 2 installed in the room R1C. In this case, when only the ventilation device 2 installed in the room R1B is operating and the ventilation device 2 installed in the room R1C is stopped, as shown in FIG. 20B, the arrow images GA2121 and GA2123 are shown in solid line frames, respectively. The arrow images may be updated to GA2131 and GA2133. Alternatively, as shown in FIG. 20C, the arrow images GA2121 and GA2123 may be updated with one arrow image GA2134 in which the solid line frame is bent. Further, when only the ventilation device 2 installed in the room R1C is operating and the ventilation device 2 installed in the room R1B is stopped, as shown in FIG. 20D, the arrow image GA2122 is a bent arrow image of the solid line frame. It may be updated to GA2135. Further, when both the ventilation devices 2 installed in the rooms R1B and R1C are operating, as shown in FIG. 20E, the arrow images GA2121, GA2122, and GA2123 in the broken line frame are the arrow images GA2131 and GA2131 in the solid line frame, respectively.

As described above, among the airflow paths reaching the outside of the building H from the rooms R2B and R2C, the display mode setting unit 113 includes the airflow generation path in which the airflow is generated and the airflow non-airflow in which the airflow is not generated. When the generation path exists, the display mode of the arrow images GA2131, GA2132, and GA2133 corresponding to the airflow generation path is set to a display mode different from the display mode of the arrow images GA2121, GA2122, and GA2123 corresponding to the non-airflow generation path. .. In this case, the rooms R2B and R2C correspond to the fourth room, and the areas GA (R2B) and GA (R2C) corresponding to the rooms R2B and R2C in the building image GA8 correspond to the fourth room.

When a ventilation device 2 having a function of generating an air flow from the rooms R2B and R2C to the room R2D is installed in the building H, the tips of the arrow images GA2121, GA2122, and GA2123 are attached to the room R2D in the building image GA8. The operation screen image may be constructed so as to overlap with the corresponding area GA (R2D). In this case, the room R2D corresponds to the fifth room, and the area GA (R2D) corresponding to the room R2D in the building image GA8 corresponds to the fifth area.

According to this configuration, for example, when the second-class ventilation fans installed in each of a plurality of rooms (for example, two rooms R2B and R2C) operate independently of each other, the user can appropriately grasp these operating states. can.

In the embodiment, when the user touches the portion corresponding to the arrow image in the input unit 305 while the operation screen image is displayed on the display unit 304, the operation mode selection menu image of the corresponding ventilation device 2 is popped up. It may be a thing.

Further, it is assumed that the ventilation device 2 which is a first-class ventilation fan with a heat exchange function is installed in the room R1C of the building H. Then, the ventilation device 2 is operated in either an operation mode in which the heat exchange function is effective or the heat exchange function is ineffective mode in which the heat exchange function is invalid.

First, the device control unit 116 determines whether or not the operation information stored in the operation information storage unit 134 is related to the ventilation device 2 (step S301). Here, if the device control unit 116 determines that the operation information is not related to the ventilation device 2 (step S301: No), the processes after step S302 are executed. On the other hand, when the device control unit 116 determines that the operation information stored in the operation information storage unit 134 is related to the ventilation device 2 (step S301: Yes), the operation content indicated by the operation information is the heat exchange function in the input unit 305.

When any of the device identification information of the ventilation device 2 operating in any of the operation modes with the mode is applicable, it is determined that the operation mode can be switched. When the device control unit 116 determines that the operation mode of the ventilation device 2 corresponding to the arrow image cannot be switched (step S3302: No), the processes after step S306 are executed as they are. On the other hand, when the device control unit 116 determines that the operation mode of the ventilation device 2 corresponding to the arrow image can be switched (step S3302: Yes), the device control unit 116 outputs the construction information including the image identification information of the operation mode selection menu image to the terminal. It is transmitted to the device 3 (step S3303). At this time, when the terminal device 3 receives the construction information including the operation mode selection symbol image identification information, the operation screen image information including the operation mode selection menu image of the ventilation device 2 corresponding to the symbol image of the first-class ventilation fan is received. Is constructed and displayed on the display unit 304.

Next, the operation information receiving unit 115 determines whether or not the operation information has been received from the terminal device 3 within the preset standby time (step S3304). Here, if it is determined that the operation information receiving unit 115 does not receive the operation information within the standby time (step S3304: No), the processing after step S304 is executed as it is. On the other hand, it is assumed that the user selects the operation mode while the operation screen image including the operation mode selection menu image is displayed on the display unit 304. In this case, the operation information receiving unit 115 determines that the operation information corresponding to the selected operation mode has been received from the terminal device 3 (step S3304: Yes). At this time, the operation information receiving unit 115 stores the received operation information in the operation information storage unit 134. Then, the device control unit 116 generates control information based on the operation information corresponding to the selected operation mode (step S307). Subsequently, the processes after step S308 are executed.
