Operations of Air Conditioning System According to Embodiment
Next, operations of the air conditioning system 1 according to the embodiment will be described. The air conditioning system 1 is installed in a large commercial facility. In the air conditioning system 1, the operational control information for controlling operations of the air conditioners 10-1 to 10-n is transmitted as required and the operating state information of the air conditioners 10-1 to 10-n is obtained and stored at prescribed time intervals by the controller 20.
Information in which the air conditioners 10-1 to 10-n are classified depending on the installation sites thereof into groups by stores or predetermined areas (such as a store A, a store B, a store C, a first floor center aisle area, and a first floor west aisle area) in the commercial facility equipped with the air conditioning system 1 is stored as the device classification information in the device classification information storage 22 of the controller 20.
An example of the device classification information is illustrated in FIG. 3. In the device classification information illustrated in FIG. 3, the air conditioners 10-1 to 10-5 correspond to a group indicating the air conditioners installed in a store A (a store A group), the air conditioners 10-6 to 10-10 correspond to a group indicating the air conditioners installed in a store B (a store B group), the air conditioners 10-11 to 10-15 correspond to a group indicating the air conditioners installed in a store C (a store C group), the air conditioners 10-16 to 10-18 correspond to a group indicating the air conditioners installed in a first floor center aisle area (a first floor center aisle area group), and the air conditioners 10-19 to 10-21 correspond to a group indicating the air conditioners installed in a first floor west aisle area (a first floor west aisle area group).
The processing performed by the controller 20 when the manager of the air conditioners 10-1 to 10-n performs operations for management work for the air conditioners 10-1 to 10-n using the controller 20 will be described by referring to the flowchart of FIGS. 4A and 4B.
First, when the manager performs an operation of displaying the management screen of the air conditioners 10-1 to 10-n on the touch panel 21 of the controller 20 (step S1: YES), operation information is detected by the operation detector 211 and obtained by the display information generator 23. The display information generator 23 generates a base air conditioner management screen as a corresponding equipment management screen. In the base air conditioner management screen, air conditioner icons 101-1 to 101-n indicating the respective air conditioners and having a first display size “medium” are superimposed on a floor configuration diagram (floor layout diagram) of the building at positions corresponding to the installation sites of the respective air conditioners 10-1 to 10-n. The generated air conditioner management screen is displayed on the touch panel 21 by the display 212 as illustrated in FIG. 5, for example (step S2). In the air conditioner management screen illustrated in FIG. 5, the air conditioner icons that are solid black circles indicate power-on states of the corresponding air conditioners 10, and the air conditioner icons that are white circles indicate power-off states of the corresponding air conditioners 10.
When the manager performs a touch operation of any of the air conditioner icons, for example, the air conditioner icon 101-1 corresponding to the air conditioner 10-1 on the base air conditioner management screen displayed on the touch panel 21 (step S3: YES), operation information is detected by the operation detector 211 and obtained by the display information generator 23.
Upon obtaining information indicating detection of the touch operation of the air conditioner icon 101-1 on the touch panel 21, the display information generator 23 updates the display information such that the display size of the air conditioner icon 101-1 displayed on the air conditioner management screen is changed to a second display size “large” that is larger than the first display size, the air conditioner icon 101-1 is highlighted by lighting up the region therearound, and an operation button 102-1 for implementing operations and settings of the corresponding air conditioner 10-1 and a group display button 103-1 for instructing display of the group to which the air conditioner 10-1 belongs are displayed at the bottom of the air conditioner management screen in a superimposed manner. In the operation button 102-1, the current operating state (power-on state/power-off state) of the corresponding air conditioner 10-1 and setting information (set temperature or the like) are displayed. The generated display information of the air conditioner management screen is displayed on the touch panel 21 by the display 212 as illustrated in FIG. 6, for example (step S4).
When the manager performs an operation with respect to the operations and settings of the corresponding air conditioner 10-1, for example, a power-off operation by means of the operation button 102-1 on the base air conditioner management screen displayed on the touch panel 21 (step S5: YES), the operation is detected by the operation detector 211 and a power-off instruction for the corresponding air conditioner 10-1 is generated as control information by the control information generator 25. The generated control information is transmitted from the communicator 24 to the corresponding air conditioner 10-1, and the power state of the corresponding air conditioner 10-1 is turned to an off state (step S6).
When the manager performs an operation on an operation-invalid position on the air conditioner management screen displayed on the touch panel 21 (step S7: YES), the display information generator 23 returns the display size of the air conditioner icon 101-1 to the first display size “medium”, terminates the lighting up of the region around the air conditioner icon 101-1, terminates the display of the operation button 102-1, and then returns the display of the touch panel 21 to the base air conditioner management screen by (step S2). Operation-invalid positions on the air conditioner management screen are positions other than the air conditioner icon 101-1 displayed at the second display size “large”, the air conditioner icons 101-2 to 101-n displayed at the first display size “medium” other than the air conditioner icon 101-1, the operation button 102-1, and the group display button 103-1.
When the operation-invalid positions are not operated in step S7 (step S7: NO) and the group display button 103-1 is operated on the air conditioner management screen as illustrated in FIG. 7 (step S8: YES), the display information generator 23 identifies all the air conditioners 10-1 to 10-5 in the store A group to which the air conditioner 10-1 belongs based on the information stored in the device classification information storage 22.
Then, the display information generator 23 updates the display information such that the display size of the air conditioner icons 101-1 to 101-5 corresponding to the identified air conditioners 10-1 to 10-5 is changed to the second display size “large” that is larger than the first display size, the lighting up of the region around the air conditioner icon 101-1 is terminated, the operation buttons 102-1 to 102-5 for implementing the settings of the corresponding air conditioners 10-1 to 10-5 are displayed at the bottom of the air conditioner management screen, and the display size of the air conditioner icons 101-6 to 101-n corresponding to the air conditioners 10-6 to 10-n in the groups other than the store A group is changed to a third display size “small” that is smaller than the first display size. The updated air conditioner management screen is displayed on the touch panel 21 by the display 212 as illustrated in FIG. 8, for example (step S9).
When the manager operates any of the operation buttons, for example, the operation button 102-2 to perform an operation with respect to the operations and settings of the air conditioner 10-2 on the displayed air conditioner management screen (step S10: YES), the operation is detected by the operation detector 211 and the corresponding control information is generated by the control information generator 25. The generated control information is transmitted from the communicator 24 to the air conditioner 10-2, and the corresponding control is performed (step S11).
When the manager performs a touch operation of any of the air conditioner icons displayed at the second display size “large”, for example, the air conditioner icon 101-1 on the displayed air conditioner management screen as illustrated in FIG. 9, the corresponding operation button 102-1 is highlighted by lighting up the region therearound (step S13). Thus, the manager can know the position of the operation button for performing an operation with respect to the operations and settings of the air conditioner located at the desired position in the floor configuration diagram.
When the manager performs an operation on an operation-invalid position described below on the displayed air conditioner management screen (step S14: YES), the display information generator 23 updates the display information such that the screen is returned to the immediately preceding screen, that is, the screen on which only the air conditioner icon 101-1 is displayed at the second display size “large” and highlighted by lighting up the region therearound and only the operation button 102-1 of the air conditioner 10-1 is displayed at the bottom of the screen. Then, the generated display information of the display information generator 23 is displayed on the touch panel 21 (step S15) and the processing returns to step S5.
In the air conditioner management screen displayed in step S9, the display information generator 23 determines that operations for the air conditioner icons 101-1 to 101-5 displayed at the second display size “large” and operations for all the displayed operation buttons 102-1 to 102-5 are valid, and determines that operations for the positions other than the aforementioned positions, for example, operations for the air conditioner icons 101-6 to 101-n displayed at the third display size “small” are invalid.
According to the embodiment above, the manager can know how the air conditioners 10-1 to 10-n in the building are classified and performs operations on the air conditioner management screen displayed on the touch panel 21. Thus, in a case where it is agreed that all the air conditioners in a prescribed store in the building are to be turned to a power-off state at a prescribed store closing time every day, the manager can know the air conditioner(s) for which a power off operation has not been performed and can perform a power-off operation therefor with an easy operation by displaying the operation buttons of the air conditioners in the store after the prescribed store closing time. Accordingly, it is possible to improve the operability of management operations of equipment devices in a large building on the touch panel 21.
In the embodiment above, when an air conditioner icon displayed at the bottom of the air conditioner management screen, for example, the air conditioner icon 101-10 illustrated in FIG. 10, is operated in step S3, and the operation button 102-10 and the group display button 103-10 are displayed at the bottom of the screen in a superimposed manner, the air conditioner icon 101-10 may be hidden by the display of the buttons in a superimposed manner and thus may not be visible. In this case, as illustrated in FIG. 11, the portion corresponding to the floor configuration diagram may be displaced to the upper side of the screen such that the operated air conditioner icon 101-10 can be reliably displayed on the screen even when the operation button 102-10 and the group display button 103-10 are displayed. Also in a case where the group display button 103 is operated in step S8 and the operation buttons corresponding to the group are displayed, when any of the air conditioner icons displayed at the second display size “large” may be hidden by the display of the buttons in a superimposed manner, the portion corresponding to the floor configuration diagram may be similarly displaced to the upper side of the screen.
In the embodiment, an example is described in which the equipment devices are air conditioners, the equipment management apparatus is a controller which manages these air conditioners, and the equipment management screen is an air conditioner management screen. However, the equipment devices are not limited to air conditioners and may be elevators, lights, machine tools, and combinations thereof, for example. The equipment management screen may be any screen as long as, in the screen, equipment device icons indicating the respective equipment devices to be managed are superimposed on a floor configuration diagram (floor layout diagram) of a building at positions corresponding to the installation sites of the respective equipment devices. The equipment management apparatus is not limited to a controller and may be a communication device with a touch screen such as the tablet terminal 50-3 and the personal computer 50-4.
While certain embodiments have been described, these embodiments have been presented by way of example only, and are not intended to limit the scope of the inventions. Indeed, the novel embodiments described herein may be embodied in a variety of other forms; furthermore, various omissions, substitutions and changes in the form of the embodiments described herein may be made without departing from the spirit of the inventions.
