{Summary of Invention}

{Technical Problem}

In the air-conditioning control and monitoring system within the building, when information for designating the settings of each air conditioner is sent thereto from the central monitoring device, the air conditioner is controlled such that the air conditioner operates on the basis of these settings. However, in the related art, when the settings are changed by the user in each room while the air conditioner is in operation, the settings designated by the central monitoring device differ from the settings set for the actual operation in the room.
In order to provide air-conditioning settings desired by the user to each air conditioner from the central monitoring device, monitoring personnel need to manually set the setting parameters one by one for each air conditioner.
Therefore, for example, in a case where there are multiple parameters for controlling the settings and there are several hundreds of air conditioners in a large-scale environment, such as a building, there would be several thousands of zones where the setting parameters would need to be set. In such a case, there is a problem in that setting several thousands of these setting parameters places a large burden on the monitoring personnel, and these several thousand setting processes cannot be performed immediately.
The present invention has been made to solve the aforementioned problem, and an object thereof is to provide an air-conditioning control and monitoring device and program, as well as an air-conditioning control and monitoring system, that can easily and immediately store the settings of an air conditioner.

{Solution to Problem}

In order to solve the aforementioned problems, the present invention employs the following solutions.
A first aspect of the present invention provides an air-conditioning control and monitoring device that controls the operation of an air conditioner in accordance with a command from a client terminal, which remote-controls the air conditioner, and that monitors an operating state of the air conditioner so as to provide information regarding the operating state of the air conditioner to the client terminal. The air-conditioning control and monitoring device includes a sending unit that sends an air conditioner setting corresponding to a predetermined timing to the client terminal; a settings storage unit that stores the setting in association with identification information when the settings storage unit receives the identification information and a store command from the client terminal having received the setting sent from the sending unit; and a control unit that reads the setting associated with the identification information from the settings storage unit when the control unit receives the identification information and a change command for changing the air conditioner setting from the client terminal, and changes the air conditioner setting to the setting read from the settings storage unit.
With such a configuration, the air conditioner setting corresponding to the predetermined (e.g., current) timing is sent to the client terminal by the sending unit. Consequently, for example, the received setting is displayed on a display unit of the client terminal. With regard to the setting, if the store command for storing the setting and the identification information are received from the client terminal, the received identification information and the setting sent to the client terminal are associated with each other and are stored in the settings storage unit. When the change command for changing the air conditioner setting and the identification information are received from the client terminal, the setting associated with the identification information received from the client terminal is read from the settings storage unit, and the control unit operates the air conditioner in accordance with the read setting.
Because the setting of the air conditioner in operation corresponding to the predetermined timing is stored as setting information on the basis of the command from the client terminal, the air conditioner setting corresponding to the timing designated by the user using the client terminal can be easily stored. Furthermore, since the setting and the name thereof are associated with each other, the previously stored setting can be readily retrieved by designating the name via the client terminal. Consequently, the air conditioner setting can be changed to the setting corresponding to a point when the setting is stored in the settings storage unit.
The aforementioned setting is, for example, an operating condition. Examples thereof include an operating day/time, an operating mode, a set temperature, a room temperature, and a setting for permitting or not permitting remote control.
In the aforementioned air-conditioning control and monitoring device, if multiple air conditioners are to be monitored, the settings storage unit may store the identification information and settings of the multiple air conditioners to be monitored in association with each other when the settings storage unit receives the store command and the identification information from the client terminal.
When there are multiple air conditioners to be monitored in this manner, the settings of the multiple air conditioners are stored in association with a single piece of identification information. Consequently, when changing the settings of the air conditioners, the user can simply input the single piece of identification information to change the settings of the multiple air conditioners to desired settings. When there are multiple air conditioners to be monitored, air conditioners in which the settings are to be stored may be selectable by the user. Consequently, it is possible to store the settings of only the desired air conditioners in the settings storage unit.
In the aforementioned air-conditioning control and monitoring device, the setting may include an installation environment of the air conditioner.
Examples of an installation environment of the aforementioned air conditioner include a room where the air conditioner is installed and a group of separate rooms for different purposes.
In the aforementioned air-conditioning control and monitoring device, the setting may be changeable by the client terminal.
Consequently, the setting of an air conditioner desired by the user can be stored.
A second aspect of the present invention provides a client terminal that monitors an operating state of an air conditioner and is connected via a network to an air-conditioning control and monitoring device that controls the operation of the air conditioner. The client terminal includes a receiving unit that receives an air conditioner setting corresponding to a predetermined timing; an identification-information adding unit that adds identification information to the setting received from the receiving unit; and a command sending unit in which, when the air conditioner setting is to be changed, the identification information is designated so that the command sending unit sends a command for controlling the air conditioner on the basis of the setting associated with the identification information.
With such a configuration, a name adding unit adds a name to the air conditioner setting corresponding to the predetermined timing received by the receiving unit. When changing the air conditioner setting, information regarding the name associated with the setting is sent so that the command sending unit sends the command for controlling the air conditioner on the basis of the setting associated with the name.
Consequently, the air conditioner setting can be remote-controlled via the air-conditioning control and monitoring device.
A third aspect of the present invention provides an air-conditioning control and monitoring system that includes the aforementioned air-conditioning control and monitoring device and the aforementioned client terminal.
A fourth aspect of the present invention provides an air-conditioning control and monitoring program that controls the operation of an air conditioner in accordance with a command from a client terminal, which remote-controls the air conditioner, and that monitors an operating state of the air conditioner so as to provide information regarding the operating state of the air conditioner to the client terminal. The air-conditioning control and monitoring program makes a computer execute first processing for sending an air conditioner setting corresponding to a predetermined timing to the client terminal; second processing for storing the setting in association with identification information when the identification information and a store command are received from the client terminal having received the setting sent by the first processing; and third processing for reading the setting associated with the identification information from the settings storage unit when the identification information and a change command for changing the air conditioner setting are received from the client terminal, and changing the air conditioner setting to the setting read from the settings storage unit.

{Advantageous Effects of Invention}

The present invention achieves the advantage of having the ability to easily and immediately store the air conditioner setting.

{Description of Embodiments}

An embodiment of an air-conditioning control and monitoring system to which an air-conditioning control and monitoring device according to the present invention is applied will be described below with reference to the drawings.

{First Embodiment}

Fig. 1 is a block diagram illustrating the schematic configuration of the air-conditioning control and monitoring system according to this embodiment.
As shown in Fig. 1, an air-conditioning control and monitoring system 30 according to this embodiment mainly includes a client terminal 1 equipped with a web browser, and an air-conditioning control and monitoring device 2. The air-conditioning control and monitoring device 2 controls the operation of air conditioners 3 in accordance with a command from the client terminal 1, monitors the operating state of each air conditioner 3, and provides the operating state of the air conditioner 3 to the client terminal 1.
The client terminal 1 receives information regarding the settings of the air conditioner 3 received from the air-conditioning control and monitoring device 2 and performs various operation control on the air conditioner 3 via the air-conditioning control and monitoring device 2. To achieve this, the client terminal 1 includes a CPU (central processing unit), a ROM (read-only memory), a RAM (random access memory), an input unit, a monitor, and the like, which are not shown.
The client terminal 1 and the air-conditioning control and monitoring device 2 are connected via a building-management communication network 4. The building-management communication network 4 is, for example, a network that uses a standard communications protocol (e.g., TCP/IP) for building management, for example, a LAN (local area network). The air-conditioning control and monitoring device 2 and the air conditioners 3 are connected via an air-conditioning control network 5. The air-conditioning control network 5 is, for example, a network that uses a standard communications protocol for controlling and monitoring the air conditioners.
Each air conditioner 3 outputs settings regarding its own operation to the air-conditioning control and monitoring device 2 at a predetermined timing. Specifically, an air conditioner 3 installed in a conference room A outputs settings regarding its own operation, i.e., "cooling operation" and "26 degrees", to the air-conditioning control and monitoring device 2 at a predetermined timing.
Regardless of whether in operation or not in operation, each air conditioner 3 outputs its settings to the air-conditioning control and monitoring device 2.
The settings are, for example, operating conditions. Examples thereof include an operating day/time, an operating mode, a set temperature, a room temperature, and a setting for permitting or not permitting remote control.
The air-conditioning control and monitoring device 2 is, for example, a computer, and includes a CPU (central processing unit), a ROM (read-only memory), a RAM (random access memory), and the like, which are not shown. A processing sequence for achieving various functions, to be described below, is stored in the ROM or the like in a program format, and the CPU loads the program into the RAM or the like and performs information processing and calculation so as to achieve the various functions, to be described below.
The air-conditioning control and monitoring device 2 includes a sending unit (sending unit) 10, a combining unit 11, a settings storage unit (settings storage unit) 12, a control unit (control unit) 13, and a receiving unit (receiving unit) 14.
The receiving unit 14 receives the settings of each air conditioner 3 and information regarding the installation environment of the air conditioner 3 at a predetermined timing from the air conditioner 3, and outputs the information to the sending unit 10.
The sending unit 10 associates the settings of each air conditioner 3, corresponding to the predetermined timing, received from the receiving unit 14 with the information regarding the installation environment of the air conditioner 3, and outputs the information to the client terminal 1. The installation environment of the air conditioner 3 is information for identifying an air-conditioning cell in which the air conditioner is installed or information for indentifying the air conditioner, and is, for example, a number assigned to the air conditioner 3 in advance or a name that indicates a specific room.
The sending unit 10 sends the settings of the air conditioner 3 corresponding to a freely-chosen timing to the client terminal 1, regardless of whether the air conditioner 3 is in operation or not in operation.
Specifically, the sending unit 10 receives, from the air conditioner 3 in the conference room A, "conference room A (e.g., identification information of the air conditioner 3 in the conference room A)" as the installation environment and "cooling operation" and "26 degrees" as the settings at a predetermined timing, and sends the information to the client terminal 1.
When the combining unit 11 receives a store command and identification information from the client terminal 1 having received the settings and the information regarding the installation environment sent from the sending unit 10, the combining unit 11 associates the identification information with the information regarding the installation environment and the settings and stores the information in the settings storage unit 12. Specifically, the combining unit 11 associates the identification information with the information regarding the installation environment and the settings on the basis of the store command sent from the client terminal 1 and stores the information in the settings storage unit 12.
The store command is sent at a freely-chosen timing (time) from the client terminal 1, and the combining unit 11 stores the setting information and the identification information in the settings storage unit 12 on the basis of the timing at which the store command is received from the client terminal 1.
Furthermore, when the combining unit 11 receives a change command for changing the settings of the air conditioner 3 and the identification information from the client terminal 1, the combining unit 11 reads the information regarding the installation environment and the settings that correspond to the identification information from the settings storage unit 12, and outputs the information to the control unit 13.
More specifically, when the combining unit 11 receives, from the client terminal 1, the identification information (e.g., "optimal summer temperature setting for conference room A") associated with the information regarding the installation environment of the air conditioner 3 (e.g., "conference room A") and the settings (e.g., "cooling operation" and "26 degrees") and the store command (e.g., a command output when a register button is pressed by a user), the combining unit 11 stores the information, for example, "conference room A", "cooling operation", "26 degrees", and "optimal summer temperature setting for conference room A", in association with each other in the settings storage unit 12.
Furthermore, for example, when the combining unit 11 receives the change command and the identification information (e.g., "optimal summer temperature setting for conference room A") from the client terminal 1, the combining unit 11 reads the information regarding the installation environment, i.e., "conference room A", and the setting information, i.e., "cooling operation" and "26 degrees", associated with the "optimal summer temperature setting for conference room A" and outputs the information to the control unit 13.
By storing the desired settings of the air conditioner 3 (in this case, the air conditioner 3 in the conference room A) in association with the identification information in this manner, the desired settings can be readily retrieved on the basis of the identification information without the need for monitoring personnel to memorize the desired settings for the conference room A.
The control unit 13 outputs the settings read from the settings storage unit 12 and acquired from the combining unit 11 to the air conditioner 3 associated with the identification information acquired from the combining unit 11. Specifically, the settings "cooling operation" and "26 degrees" are output to the air conditioner 3 in the conference room A.
Fig. 2 is an example of a screen showing a list of settings sent from the air-conditioning control and monitoring device 2 and displayed on the client terminal 1 when setting the identification information in association with the settings.
As shown in Fig. 2, for example, the list of settings is displayed in the form of a table. Fig. 2 shows the current settings of multiple air conditioners in a certain arrangement. On this screen, the user can input, in a name input section, identification information to be associated with the current settings of each of the multiple air conditioners. Moreover, by selecting an operating section (e.g., a register button) on the screen for storing these settings in the air conditioners 3, the settings for the multiple air conditioners shown in Fig. 2 can be collectively stored in the settings storage unit 12.
When the combining unit 11 receives the identification information from the client terminal 1, the combining unit 11 reads the setting information associated with the identification information from the settings storage unit 12 and sends this information to the client terminal 1; in this case, the screen to be displayed on the client terminal is identical to the screen shown in Fig. 2.
When an operating section (e.g., a send button) on the screen for sending the settings to the corresponding air conditioner 3 is selected, the combining unit 11 outputs the setting information associated with the identification information to the control unit 13, and the control unit 13 sends the settings to the air conditioner 3 to be controlled.
An operation of the air-conditioning control and monitoring system of this embodiment will be described below.
When the settings "cooling operation" and "26 degrees" and the information regarding the environment "conference room A" in which the corresponding air conditioner 3 is installed are output from the air conditioner 3 to the air-conditioning control and monitoring device 2, the information is received by the receiving unit 14. The information regarding the installation environment "conference room A" and the information regarding the settings "cooling operation" and "26 degrees" received by the receiving unit 14 are sent to the client terminal 1 via the sending unit 10. Thus, a screen for registering the settings is displayed on the screen of the client terminal 1. Upon confirming this screen, if the user desires to register the settings "conference room A", "cooling operation", and "26 degrees", the user can input, for example, "optimal summer temperature setting for conference room A" as identification information corresponding to the settings and can perform a register command operation on the client terminal 1.
Consequently, the identification information "optimal summer temperature setting for conference room A" and a store command are sent from the client terminal 1 to the air-conditioning control and monitoring device 2. Thus, the combining unit 11 associates the identification information "optimal summer temperature setting for conference room A", the settings "cooling operation" and "26 degrees", and the information regarding the installation environment "conference room A" with each other, and stores the information in the settings storage unit 12.
If the user desires to change the current settings to the settings stored in the air-conditioning control and monitoring device 2, the user can input identification information corresponding to the settings to be changed, e.g., identification information "optimal summer temperature setting for conference room A", via the client terminal 1 so as to instruct changing of the settings. Thus, the change command and the identification information "optimal summer temperature setting for conference room A" are sent to the air-conditioning control and monitoring device 2. When the combining unit 11 receives the change command and the identification information "optimal summer temperature setting for conference room A", the settings "cooling operation" and "26 degrees" and the information regarding the installation environment "conference room A" associated with the identification information "optimal summer temperature setting for conference room A" are read from the settings storage unit 12. Moreover, the combining unit 11 sends, to the control unit 13, a control command for setting the settings to "cooling operation" and "26 degrees" for the conference room A corresponding to the air conditioner in the read installation environment.
When the control unit 13 receives the control command, the settings "cooling operation" and "26 degrees" are sent to the air conditioner 3 in the conference room A, whereby the settings for the air conditioner 3 in the conference room A are changed to "cooling operation" and "26 degrees".
As described above, with the air-conditioning control and monitoring device and program and the air-conditioning control and monitoring system of the present invention, the settings of an air conditioner corresponding to a predetermined (e.g., current) timing are sent to the client terminal 1 by the sending unit 10. Consequently, for example, the received settings are displayed on a display unit of the client terminal 1. With regard to the settings, when a store command for storing the settings and identification information are received from the client terminal, the received identification information and the settings sent to the client terminal are associated with each other and are stored in the settings storage unit 12. When the combining unit 11 receives a change command for changing the settings in the air conditioner and the identification information from the client terminal, the settings corresponding to the identification information received from the client terminal are read from the settings storage unit 12, and the control unit 13 performs the operation of the air conditioner in accordance with the read settings.
Because the settings of the air conditioner in operation corresponding to the predetermined timing are stored as setting information on the basis of the command from the client terminal 1, the settings of the air conditioner corresponding to the timing designated by the user using the client terminal 1 can be easily stored. Furthermore, since the settings and the name thereof are associated with each other, the previously stored settings can be readily retrieved by designating the name via the client terminal. The retrieved settings can be sent to the air conditioner 3 in accordance with the change command from the client terminal 1. Consequently, the settings of the air conditioner 3 can be immediately changed to the settings corresponding to a point when the settings are stored in the settings storage unit 12.
Furthermore, unlike a case where data is stored on a regular basis, the air-conditioning control and monitoring device 2 according to this embodiment stores data at a desired timing so as to avoid unnecessary data accumulation.
The user can also make the air-conditioning control and monitoring device 2 store settings that do not cause a contracted power demand to be exceeded via the client terminal 1 by using identification information such as "peak cut level A". For example, if it is predicted that the aforementioned contracted power demand might be exceeded, the preliminarily stored identification information "peak cut level A" is selected so as to send and apply the settings to the corresponding air conditioner.
In an emergency situation such as when the contracted power demand is exceeded, there is no time for the user (monitoring personnel) to individually edit the settings of the multiple air conditioners since the contracted power demand can possibly be exceeded while the editing is being performed. Therefore, by preliminarily storing the settings that do not cause the contracted power demand to be exceeded, the changed settings can be immediately sent when a critical situation is about to arise, whereby a process for avoiding such a critical situation can be easily performed.

{First Modification}

In the air-conditioning control and monitoring device 2 according to this embodiment, although the change command for changing the settings in each air conditioner on the basis of the identification information stored in the settings storage unit 12 is sent from the client terminal 1, it is not limited to this.
For example, a predetermined condition may be stored in association with the identification information stored in the settings storage unit 12 so that, when the predetermined condition is satisfied, the settings associated with the identification information stored in association with the predetermined condition may be output to the control unit 13.
An example to be set as the predetermined condition is, for example, a day/time setting for scheduling the operation. Specifically, in an environment where there are several hundreds of air conditioners within an entire building, this is used when operating all of the air conditioners in the entire building in an energy-saving mode during lunchtime.
More specifically, the settings storage unit 12 of the air-conditioning control and monitoring device 2 stores information set as an energy-saving mode. The user uses the client terminal 1 to set identification information "energy-saving mode" relative to the settings "cooling operation", "28 degrees", and "low airflow" and to store the information in the settings storage unit 12.
Fig. 3 illustrates an example of a scheduling screen sent from the air-conditioning control and monitoring device 2 and displayed on the client terminal 1 when setting the schedule for the air conditioners. Specifically, as shown in Fig. 3, information regarding a target installation environment "entire building" is selected in an air-conditioning cell, a scheduled operating time frame "12:00 to 12:55" is set, identification information "energy-saving mode" corresponding to the settings to be changed is selected, and a set button is pressed. Consequently, even when the air conditioners in the entire building are in different operating states, the settings storage unit 12 sends the settings for the energy-saving mode to the air conditioners in the entire building for the timeframe between 12:00 and 12:55.
In the case of educational facilities or the like, the schedule for using the air conditioners is frequently changed depending on semesters, classrooms, classes, and the like. For example, the air conditioners are switched between a summer setting mode and a winter setting mode, or are switched between a weekday-class-session setting mode and a long-vacation setting mode. In this case, if the settings that have previously been changed are to be reset back to the previous settings, it is necessary to memorize the settings of the individual air conditioners. In addition, the process for restoring the original settings of the multiple air conditioners is time-consuming. With the air-conditioning control and monitoring device 2 according to this embodiment, the settings for each condition are stored together with the identification information, and the reading of the stored identification information is scheduled (by, for example, designating a specific day/time and reading the identification information at the aforementioned day/time), thereby sending desired settings to the air conditioners at a desired timing. Consequently, changing of the settings can be automatically performed in accordance with the schedule, and the settings of the air conditioners can be easily changed.
By scheduling the changing of the settings on the basis of the identification information preliminarily stored in the settings storage unit 12 of the air-conditioning control and monitoring device 2 in this manner, desired settings for a specific day/time can be reliably and easily sent to the air conditioners. In a large-scale building having several hundreds of air conditioners in the entire building, it is necessary to set several thousands of settings, and the process for changing several thousands of settings involves an enormous amount of time and labor for the monitoring personnel. With the air-conditioning control and monitoring device 2 according to this embodiment, the changing of the settings is scheduled, as mentioned above, and the process for changing several thousands of settings is collectively performed on the basis of the identification information, whereby desired settings can be easily and immediately sent to the air conditioners.

{Second Modification}

In the air-conditioning control and monitoring device 2 according to the embodiment of the present invention, the settings may be changed in association with other actions, instead of being changed manually by the monitoring personnel or changed in accordance with a schedule set to a specific day/time.
For example, based on the store command from the client terminal 1, the settings storage unit 12 of the air-conditioning control and monitoring device 2 stores a setting "stop operation" for the air-conditioning cell "entire building" in association with identification information "fire", as a setting when a fire occurs. Moreover, the air-conditioning control and monitoring device 2 operates in cooperation with other software, and when a message indicating that a fire is detected is received from that software, the identification information "fire" is selected. Accordingly, when a fire occurs, a notification that the fire has occurred is received by the air-conditioning control and monitoring device 2, and the identification information "fire" is read from the settings storage unit 12 so that "entire building" and "stop operation" associated with "fire" are selected. Furthermore, the control unit 13 sends the setting "stop operation" to the air conditioners corresponding to the air-conditioning cell "entire building".
By operating in cooperation with the information detected by the software and changing the settings on the basis of an event that has occurred, a high-risk operating state can be avoided. If a hazardous event occurs while the monitoring personnel are remote from the client terminal 1, the settings associated with the pre-registered identification information are automatically sent, whereby the air conditioners can be controlled to a desired operating state even when the monitoring personnel are not present.
Although the settings storage unit 12 in the air-conditioning control and monitoring device 2 according to this embodiment described above is configured to set and store the identification information related to the setting information of a single air conditioner, it is not limited to this. For example, the identification information may be set for the setting information of multiple air conditioners to be monitored, or air conditioners in which the settings are to be stored may be selected from among multiple air conditioners by the user.
Consequently, it is possible to store the settings of only the desired air conditioners in the settings storage unit 12.
In the air-conditioning control and monitoring device 2 according to this embodiment, although the settings storage unit 12 is configured to store the settings sent to the client terminal 1 from the sending unit 10 when the settings storage unit 12 receives the store command and the identification information from the client terminal 1, it is not limited to this. For example, the settings may be changeable by the client terminal 1. Thus, the settings of desired air conditioners can be stored in the settings storage unit 12.
Although the embodiment of the present invention has been described above in detail with reference to the drawings, the detailed configuration is not limited to that in this embodiment, and design modifications are permissible so long as they do not depart from the spirit of the invention.
