Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a centralized control device for an air conditioner.

[0002]

2. Description of the Related Art FIG. 1 is a block diagram showing the configuration of a centralized control device for a general air conditioner installed in a building. In FIG. 1, 11 is a building management system for controlling the entire facility. Is a central control device for an air conditioner as one management item of this building management system, 1a to 1n are air conditioners to be controlled, 14 is a building management system 11 and a central control device 4 for the air conditioner. Communication cable for
Reference numeral 15 is a network for centrally controlling the air conditioners 1a to 1n. In addition, the central control device 4 of the air conditioner
Centrally controls the air conditioners 1a to 1n dispersed in the building.

In such a system, when the air conditioner is operated according to the schedule of the building management system, for example, the procedure shown in FIG. 9 has been conventionally performed. FIG. 9 shows a simple communication process between the building management system 11 and the centralized control unit 4 of the air conditioner. The operation of the air conditioner group preset on the building management system side at the schedule point 1 is performed. This has been realized by reporting the status setting information to each air conditioner via the central control device of the air conditioner.

Further, FIG. 10 is a configuration diagram showing a main configuration of a control device for a conventional air conditioner. In FIG. 10, the air conditioner includes an indoor unit and an outdoor unit. 1a, 1b, 1c, 1d, 1e and 1f are indoor units (hereinafter collectively referred to as indoor unit 1),
Reference numerals 2a, 2b, 2c, and 2d denote remote controllers (hereinafter collectively referred to as remote controller 2) that control the operation of indoor units arranged in each room.
a and 3b are outdoor units (hereinafter, collectively referred to as outdoor units 3), 5 is a display of setting data such as group number of each indoor unit in the central control device 4, operation setting data, and operating state of each indoor unit. The display circuit 6 performs input of various setting data and switches the display contents. Reference numeral 7 receives operation information from the indoor unit 1, the remote controller 2, and the outdoor unit 3 and operation setting data from the centralized control device. , A clock circuit for counting time, 9 is a microcomputer (CPU) for arithmetically processing input data from the input circuit 6 and received data from the transmission circuit 7, and uses a RAM. It has a data memory 9a and a program memory 9b using a ROM.

Although the conventional control device is constructed as described above, in FIG. 10, a combination of an indoor unit and a remote controller, that is, a combination of 1a, 1b, 2a, a combination of 1c, 1f, 2b, 1d, 2c. When performing group operation control with the combination of 1e and 2d, conventionally, different unit numbers are set for multiple indoor units, remote control numbers that match the group number are set for the remote controller, and outdoor units are also set. After setting the same unit number for a plurality of connected indoor units for a plurality of units, the centralized control device configured a group as follows. First, use the unit numbers and remote control numbers set for each indoor / outdoor unit and remote controller to configure a group with a centralized control device, assign group numbers to indoor / outdoor units, and group numbers to indoor / outdoor units. The central control unit also stores each data, and next, in order to facilitate control operation in the central control unit, a group number and a group number so that the group and the name are one-to-one By allocating room names etc. as group names, the operation control unit of the air conditioner by the remote controller and the operation control unit of the air conditioner by the central control unit are made equal, and the operation status setting by the remote controller and the central control unit The operation status setting was the same.

Further, when performing the schedule operation of the air conditioner by the centralized control device shown in FIG. 10, since detailed schedule control operation is performed according to the installation location and application of the air conditioner, each room is set in the operation setting time. When the operation control signal can be selectively set to be valid / invalid by the remote controller provided and the operation control signal is made valid by the remote controller, operation control can be performed by either the centralized control device or the remote controller. Further, when the operation control signal from the remote controller is invalidated, the operation control can be performed only by the centralized control device. Further, during the operation stop set time, the operation control signal by the remote controller arranged in each room is invalidated, and the operation and stop by the centralized control device are also invalidated.

When the centralized control unit in FIG. 10 prohibits the re-operation of a plurality of air conditioners after the required time, the operation start time and the operation stop time are set,
Scheduled operation of the air conditioner is performed according to these set times, and during the scheduled operation, an operation is performed to invalidate the operation control by the remote controller arranged in each room.

[0008]

In the above air conditioner, if the number of air conditioners to be controlled is large, it takes time for communication between the building management system side and the centralized control device of the air conditioner. Also, there is a problem that the amount of communication processing becomes enormous.

In addition, after the initial system construction, if there is a change in the room configuration or usage environment, in all systems,
There is a problem that the group number stored in each indoor / outdoor unit and the remote controller and the data necessary for the group configuration of the centralized control device need to be reset, and the setting operation may be cumbersome and the setting error may occur. was there.

Further, since the operation signal from the centralized control device and the operation signal from the remote controller are invalid during the operation stop time period in the schedule operation, the schedule operation by the centralized control device is stopped when the user wants to drive in a hurry. Therefore, it is necessary to perform the operation setting operation, and after the operation for the required time, the setting operation must be performed again in order to shift to the scheduled operation, which is troublesome in use.

Further, when the scheduled operation is performed, it is necessary to set the operation start time and the operation stop time for all the groups including a plurality of air conditioners, which makes the setting operation complicated. In addition, when the administrator of the centralized control device does not perform the scheduled operation, the operating status of all groups consisting of multiple air conditioners is confirmed, and operation or stop of each group is checked. Since the operation for invalidating the operation control by the remote controller arranged in the room has to be performed, the operation is troublesome.

The present invention has been made to solve the above problems, and simplifies the contents of communication between a building management system and a centralized control unit of an air conditioner, so that the building management system can be operated in a short time. The purpose is to obtain a control device that can receive information.

In addition, the centralized control device does not change the setting data necessary for the group configuration in each room, the outdoor unit and the remote controller, and the group configuration is integrated into a larger group configuration.
The purpose is to reduce the setting operation when changing the room configuration and usage environment after the system is constructed, to reduce the troublesome setting operation and to eliminate the risk of setting error.

In addition, even during the operation stop time, it is possible to select the operation enable / disable mode selection by the remote controller for each group of air conditioners, and when it is enabled, the operation can be stopped in the central control unit. The purpose is to be able to flexibly deal with air conditioners of various installation locations and uses, and to enable operation of the air conditioner without interrupting scheduled operation.

Further, when the operation of the air conditioner by the remote controller becomes unnecessary and the operation is stopped by the remote controller in each room, the operation control signal by the remote controller in the corresponding room remains valid thereafter. The purpose is to allow the centralized control device side to freely select the mode, that is, to invalidate it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In the system configuration shown in FIG. 1, a simple block configuration diagram of the centralized control device 4 of the air conditioner is shown in FIG. In FIG. 2, 6a is a communication circuit for communicating with a higher-level building management system, 6b is a switch unit for performing operation settings, 9 is a microcomputer for controlling, and 9a is necessary for the microcomputer 9. A storage unit for storing data, a transmission circuit 7 for communicating with a plurality of air conditioners 1a to 1n to be managed, and a display unit 5 for displaying the operating state of the air conditioner.

In the centralized control device 4 for an air conditioner thus configured, as shown in FIG.
Combination pattern 1 of the operating states of each 1n air conditioner
Up to N patterns are stored in the storage unit 9a, and a pattern number is obtained from the building management system as shown in FIG. 4 to select a corresponding pattern and to select a plurality of air conditioners based on the pattern data. A control command is issued to 1a to 1n. For example, when the command of pattern 1 is received from the building management system via the communication circuit 6a at the schedule point 1 of the building management system, the transmission circuit 7 is transmitted in accordance with the pattern data shown in FIG. “Operation, cooling, set temperature 27 ° C.” is transmitted to the air conditioner 1a via the air conditioner 1b, and “Operation, cooling, set temperature 28 ° C.” is sent to the air conditioner 1b, and “Stop” is set for the air conditioner 1c. ”
To the air conditioner 1d, "stop", to the air conditioner 1e
Operation, cooling, set temperature 27 ° C "to the air conditioner 1f"
“Operation, cooling, set temperature 28 ° C.”, ..., “Operation, cooling, set temperature 27 ° C.” is transmitted to the air conditioner 1n. In this case, the central control unit of the air conditioner returns to the building management system. The response is only for notifying that the communication from the building management system has been normally received as shown in Fig. 4. The definition of each pattern is stored in the building management system and the air as shown in Fig. 6. This is performed by receiving the pattern definition from the building management system side at the time of starting the connection of the centralized control device of the harmony machine, and it is also possible to easily add or change the pattern definition from the building management system side. It goes without saying that the definition of each pattern and the addition or modification of the pattern definition can be performed in the centralized control device itself.

As shown in FIG. 5, a plurality of operation pattern numbers set in the building management system are collectively received from the building management system so that the centralized control device itself can use the plurality of operation pattern numbers to generate a corresponding pattern. It is also possible to select, and then issue a control command to the plurality of air conditioners 1a to 1n based on the respective pattern data. In this case, the response returned from the central control unit of the air conditioner to the building management system is only a response indicating that a plurality of operation patterns have been normally received. This allows faster and easier communication than in the embodiment of FIG. In addition, although the case where a plurality of operation pattern numbers is received once is shown here, it goes without saying that the operation pattern numbers can be divided into a plurality of times and received as needed.

FIG. 7 shows a connection structure between the building management system and the centralized control device. Reference numeral 6c is a contact input section for connecting to the building management system. Here, four points of contacts 1 to 4 are used. Since the contact input is provided, up to 16 types of patterns can be selected by combining the opening and closing of each contact. However, in this case, it is necessary to set the pattern definition contents in the central control device of the air conditioner in advance. In this example, it is possible to reduce the number of contact points connected to the building management system regardless of the number of centralized control devices of the air conditioners to be managed.

FIG. 8 shows another embodiment of the connection structure between the building management system and the centralized control device.
One contact is provided, and contact 1 receives four pulse signals of code information that encodes a pattern number, and contact 2 receives four strobe pulse signals indicating the timing of receiving the pulse signal input to contact 1. To do. For example,
When "0011" is received as a pulse signal at the contact 1, the pulse receiving circuit 6d recognizes the value 3 and the pattern 3
Is selected. In this example, it is possible to further reduce the number of connection points with the building management system as compared with the case of FIG. 7.

FIG. 10 is a configuration diagram showing the configuration of the main part of an air conditioner according to another invention. In FIG.
A is a remote control means, which is a remote controller 2a,
2b, 2c, 2d. Further, A is an operation means arranged for each group for a plurality of air conditioners arranged in each room, and the unit capable of operation control is the group unit. B is a centralized control means,
It is composed of the centralized control device 4 and controls the operation of the air conditioner. C is a storage unit that stores various setting data, operation status data, and the like.

Operation of one embodiment of the present invention is shown in FIG.
And it demonstrates with the flowchart of FIG. 11
And in FIG. 12, the group configuration data of the air conditioner is set by the initial data setting before the system operation of the air conditioner is started (step 11), and this signal is transmitted to the air conditioner (step 13), Group configuration data is stored for each air conditioner, and only data that matches the air conditioner side is stored in the data memory 9a (step 1
5). When this process is completed for all the air conditioners, a group name such as a room name is then set (step 18) and is also stored in the data memory 9a (step 20). There is no signal transmission to the air conditioner here,
The settable number is the number of indoor units whose operation can be controlled by the centralized control device. After the group name setting process is completed,
Perform the process of assigning group names (step 2)
1). In addition to this, when the setting of necessary data is completed, the system operation of the air conditioner becomes possible (step 2
4). The initial data can be referenced and changed even during system operation. Here, since the operation control unit of the centralized control device is the group name unit, in order to make it equal to the group configuration of the air conditioner, at the time of assigning the group name, it becomes 1: 1 for each group. It becomes possible by assigning a group name, and
If it is necessary to change the configuration of each room or the usage environment after the system is built, it is possible to easily change the settings simply by changing the assignment of group names according to the changed situation.

Further, although the case where the central controller of the air conditioner transmits the setting data to each air conditioner has been described here, the data of the operation / stop distribution, the set temperature, and the remote temperature are transmitted to all the air conditioners. It is also possible to set valid / invalid data of the operation by the operation means and wind speed switching data all at once.

Next, another embodiment of the invention will be described with reference to the flow charts of FIGS. 10 and 13 to 16.
FIG. 10 is a main part configuration diagram of a control device for an air conditioner that is an embodiment of the present invention, and its configuration is the same as that of the conventional example. FIG. 13 is a flowchart for controlling the operation of the embodiment,
14 is a flowchart showing the contents of the schedule operation control in FIG. 13, and FIGS. 15 and 16 are flowcharts following FIG. In FIG. 10, A is a remote control means, which is a remote controller 2a, 2b, 2c, 2d.
Is a unit for controlling a plurality of air conditioners, each of which is arranged in each room and constitutes a group. 2a to 2d are collectively referred to as a remote controller 2. The air conditioner is composed of an indoor unit and an outdoor unit. 1a, 1b, 1c, 1d, 1e,
1f is an indoor unit, and these are collectively referred to as an indoor unit 1. The outdoor units 3a and 3b are collectively referred to as an outdoor unit 3. B is a centralized control means, which is constituted by the centralized control device 4 and is a means for controlling the operation of the air conditioner. C is a storage means, which is composed of the data memory 9a and is a means for storing the data of the operation start time and the operation stop time for each group of the plurality of indoor units 1 which are grouped. D is an operation mode selection means, which is composed of the microcomputer 9 and can freely select whether the operation control signal from the remote control means A is valid or invalid. E is an arithmetic control unit, which is composed of the microcomputer 9 and calculates an operating time period, a stop time period, and the like in the scheduled operation.

Operation of the above embodiment is shown in FIGS.
The flowchart will be described. First, step 10
Set the setting information with. Here, setting is performed only when setting of setting information is necessary. The operation time zone (minimum unit: 5 minutes), which is a set of the operation start time and the operation stop time by the schedule operation, is set for each group so that it is within four per operation pattern. This pattern can be set and input up to 3 patterns for each group except the all-day stop mode. Upon completion of this time setting, whether to enable or disable the operation control signal by the remote operation means of the operation time zone of the air conditioner in the scheduled operation is selected and set according to the setting environment and usage status of the indoor unit. .. Subsequently, the operation control signal by the remote operation means during the operation stop time of the air conditioner in the scheduled operation is also selectively set. Then, these data are stored in the data memory 9a for each group, and the scheduled operation of this embodiment is started. When the scheduled operation is started, if the scheduled operation ON / OFF operation is not performed in step 11, it is determined in step 12 whether the scheduled operation is currently in progress. If the scheduled operation is not in progress, the scheduled operation is not performed, and at the set time. Regardless of the central control device 4 and the remote control means 2, the operation is controlled by the operation control signal generated by the operation of each input circuit (step 10). If the schedule operation is in progress, the schedule operation control of step 13 is continued. It When the scheduled operation on / off operation is performed in step 11, it is determined whether or not the scheduled operation is on / off operation in step 14. If it is the off operation, the schedule operation flag is turned off and the operation control signal by the remote controller 2 is validated. The operation of the indoor unit of the relevant group is stopped (step 16). Also, if it is an input operation,
After turning on the schedule operation flag, the schedule operation is started, and the control shifts to the schedule operation control. The control signals from the centralized control device 4, the remote controller 2 and the operation control state of the air conditioner when the valid / invalid selection of the operation control signal by the remote controller 2 during the operation time zone of the air conditioner are set as in the conventional case. Since it is similar, it is omitted. Even during scheduled operation, the operation start time and operation stop time are set, and the remote controller 2
It is possible to freely set whether the operation control signal is valid or invalid, and it is possible to immediately respond after the change. When the operation control signal from the remote controller 2 during the operation stop time zone of the air conditioner is enabled, the operation of the air conditioner is stopped at the operation stop time regardless of the inputs of the centralized control device 4 and the remote controller 2. Also, when the operation start time comes, the operation is started, but during the operation stop time zone from the operation stop time to the operation start time, the operation control of the air conditioner by the input of the centralized control device 4 and the remote controller 2 is performed. Since it is possible, the operation of the air conditioner can be restarted and stopped by the centralized control device 4 and the remote controller 2 or only by the centralized control device 4 without changing the set time even in the operation stop time zone. In the case of the operation control of the air conditioner by the centralized control device 4 and the remote controller 2, the operation is restarted by either one of the operating means in accordance with the principle of boosting priority. This is suitable for controlling the air conditioner in a usage situation in which there is a possibility that, after the manager is absent, a sudden overtime work starts and the air conditioner is operated.

Another embodiment of the invention will be described. When the operation of the air conditioner is stopped by operating a switch in the remote controller 2 while the air conditioner is being operated by the remote controller 2, an operation stop signal is transmitted from the remote controller 2 to the centralized control device.
On the other hand, in the centralized control device, in step 10 of the flowchart of FIG. 17, in the air conditioner system, it is selected again whether the operation control signal of the remote controller 2 is valid or invalid. Also, the operation can be restarted and the operation setting data can be changed by operating the remote controller 2 in each room. In addition, if it is invalid, the following flow is executed. In step 11, it is judged whether the air conditioner is in operation or not. If it is in operation, the operation is stopped by the operation control signal of the remote controller 2 based on the operation status data input from the transmission circuit. If it is determined that the operation is stopped, a command signal is passed through the air conditioner so as to invalidate the operation control signal of the remote controller 2 arranged in the group of the air conditioners whose operation is stopped. Then, it is stored here and then transmitted to the remote controller 2. The remote controller 2 receives and stores the invalid command signal, and thereafter invalidates the input by the switch operation until the valid signal is received. By the above operation, when it is desired to prevent the restart of the operation by the remote controller 2 in each room during the time period when the air conditioner does not need the air conditioner, the operation can be performed without performing the scheduled operation. There is no need for the procedure of requesting the user to change the operation setting data of each room and the operation of setting the data necessary for the scheduled operation on the administrator side. The central controller controls the remote controller 2 to determine whether the operation control signal is valid or invalid. For example, in a computer room, air conditioning is required during computer operation, but in such a room, the operation control signal from the remote controller 2 needs to be enabled, and in a room such as a conference room that is not normally used after the scheduled time. The operation control signal of the air conditioner by the remote controller 2 is enabled during the scheduled time and disabled after the scheduled time.

[0037]

As described above, according to the present invention, it is possible to shorten the communication time between the building management system and the centralized control unit of the air conditioner when the daily scheduled operation set by the building management system is realized. Moreover, there is an effect that the communication processing with the building management system can be simplified.

Further, according to another invention, since the number of communication lines between the building management system and the centralized control device of the air conditioner can be reduced, it is possible to provide an inexpensive centralized control device. is there.

Further, according to another invention, the group configuration of the air conditioner is further roughly classified by the group name, and the operation control can be performed for each group name. Therefore, it is necessary to change the group configuration after the system is constructed. Even if a problem occurs, it is not necessary to change the setting data of the group configuration on the air conditioner side and the setting process for the air conditioner of the relevant group, and it is possible to deal with it only by changing the group name assignment. This has the effect of reducing annoyance and setting mistakes.

According to another aspect of the invention, by enabling / disabling the operation control signal by the remote operation means during the operation stop time zone at the time of setting the schedule operation time, the schedule can be selected if the operation is enabled. Even when the administrator is absent during the operation stop time during operation, the operation control of the air conditioner can be performed without changing the set time by the remote operation means arranged in each room. That is, in the centralized control device, there is no need to change the settings such as the time,
This has the effect of saving labor in operations.

According to still another aspect of the present invention, the operation of setting the operation start time and the operation stop time is unnecessary, and the trouble is eliminated. Also, while the operation by the remote control means is effective, the air conditioner is operated or stopped by the user of each room by the remote control means, so as the administrator of the centralized control unit, the operation of stopping the operation for all groups is performed. This has the effect of eliminating the need for setting operations such as.
