Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for centrally managing a plurality of air conditioning (hereinafter referred to as air conditioning) units.

[0002]

2. Description of the Related Art When a plurality of air conditioning units are installed in a building, they are connected to a centralized control device so that the centralized control device can set each air conditioning block.
The air conditioning unit consists of an indoor unit and an outdoor unit.To this air conditioning unit, a hand-operated device that transmits the setting signal and displays the status of the air conditioning unit is connected. An air conditioning block is composed of interlocking units such as a ventilation unit and a heat source unit that change their states in conjunction with the air conditioner and the air conditioning unit.

The conventional air conditioning management device is constructed as described above and is operated as follows. (1) The centralized control unit and the local operation unit can set the interlocking relationship between the air conditioning unit and the interlocking unit, and operate the interlocking unit air conditioning unit without operating (operating / stopping) the interlocking unit. The interlocking unit can be operated (started / stopped) only by itself.

(2) In the centralized control device, the user sets the number and attributes (models) of the air conditioning units to be operated, and the operation contents are communicated between the air conditioning unit corresponding to this setting and the centralized control device. It If the air conditioning unit does not exist at the set address or if the attributes are different, communication with the air conditioning unit is not established and a communication error occurs.

(3) In order to manage a plurality of air conditioning units as one group so that the same operations are performed, all the air conditioning units in the group are monitored for operation contents of the air conditioning units at intervals of several minutes. A monitor request for sending is sent. When an air conditioning unit having an operation content different from the operation content in the group is detected, the setting is transmitted again to the air conditioning unit so that all the air conditioning units in the group have the same operation content.

(4) The function setting of the air conditioning unit can be changed by a switch provided on the control board of the air conditioning unit.

[0007]

The conventional air conditioning management device as described above has the following problems. (1) Although it is possible to set the interlocking relationship between the air conditioning unit and the interlocking unit from the central control unit or the local controller,
The interlocking relationship cannot be changed in association with a normal operation command. Therefore, to change the linkage,
It is necessary to perform re-operation for changing the interlocking relationship by using the centralized control device or the local controller.

(2) In the initial communication between the centralized control device and the air conditioning unit, if the air conditioning unit that should exist in the system configuration preset in the centralized control device is not actually installed, that air conditioning unit It is possible for the centralized control device to detect this communication error.
However, if an air conditioning unit that should not exist in the system configuration preset in the centralized control device is actually installed, the centralized control device cannot detect this.

(3) Since a plurality of air conditioning units are managed as one group so that they can be operated in the same manner, all the air conditioning units in the group are subject to the operation contents of the air conditioning unit at intervals of several minutes. When a monitor request is sent and an air conditioning unit with an operation content different from the group operation content is detected, the settings are sent again to that air conditioning unit so that all the air conditioning units in the group have the same operation content. . Therefore, the centralized control device needs to send a monitor request to all air conditioning units and receive the responses from all air conditioning units and compare them with the group operation contents. It is unavoidable that communication is wasted due to the internal operation image shift.

(4) The function setting of the air conditioning unit can be changed by the switch provided on the control board of the air conditioning unit itself, but this setting cannot be changed by the centralized control device.

The present invention has been made to solve the above problems, and an object thereof is to provide an air conditioning management device as described below. (1) The air conditioning management device according to the first and second aspects of the present invention changes the operation content for the air conditioning unit from the centralized control device, and at the same time, the interlocking unit operates the optimal interlocking for air conditioning after changing the operation content of the air conditioning unit. Allows you to change to a unit.

(2) In the air conditioning management device according to the third and fourth aspects of the present invention, at the time of initial communication between the centralized control device and the air conditioning unit, there is a difference between the system configuration set in advance and the system configuration actually installed. , To be detected by all centralized control devices. (3) The air conditioning management device according to the fifth aspect of the present invention realizes the operation image matching process within the group with a simple operation, and reduces the load on the centralized control device.

(4) The air conditioning management device according to the sixth aspect of the present invention enables the function settings of the air conditioning unit to be automatically restored by communication.

[0014]

Next, the operation of this embodiment will be described with reference to FIGS. Settable address range from 001 to
If it is set to 050, the attribute monitor means 21 sets the address 00.
Send an attribute monitor request to all of 1 to 050,
Receive the response. Now, the attributes (models) of the air conditioning units 1 and 4 are AH (air handling unit) and VAV.
Assuming that there are two types (bubbling unit), the central control device 1
It is assumed that 1 receives an attribute monitor response “AH001” from the air conditioning unit 1 when an attribute monitor request is made to the air conditioning unit 1 having the address “001” and the attribute AH.

The address is "002" and the attribute is VA.
When an attribute monitor request is made to the V air conditioning unit 4,
It is assumed that the attribute monitor response “VAV002” is received, and when the attribute monitor request is made to the air conditioning unit having the address “003” and the attribute VAV, there is no attribute monitor response. These response results are displayed on the screen of the display unit 23 shown in FIG. 8 by the attribute display means 22. That is,
At the address "001", the setting attribute (centralized control device 11
Since the type of air conditioning unit set by the user is AH and the installation attribute (type of air conditioning unit detected by the centralized control device 11 communicating with the air conditioning unit) is also AH, the determination is “OK”.

At the address "002", the setting attribute is AH.
Since the installation attribute is VAV, the determination is “attribute error”. At the address "003", the setting attribute is VAV
Since there is no response of the installation attribute, the judgment is "no ACK"
Becomes That is, it is determined that the air conditioning unit does not exist. At the address “004”, the setting attribute is VAV
Since the installation attribute is AH, the judgment is "attribute error"
Becomes At the addresses "005" and "006", the setting attribute is VAV and there is no response of the installation attribute, so the determination is "ACK".
None. "

At addresses "007" and "008", both have no setting attribute and both have installation attributes of VAV, so the determination is "installation error". That is, it is determined that the air conditioning unit has been detected although the air conditioning unit should not exist. Although the addresses "001" to "013" are displayed on the screen of the display 23 of FIG. 8, the address "0" is displayed by operating the scroll bar 23a.
14 "to" 050 "are also displayed.

In this way, the centralized control unit 11 sends an attribute monitor request to confirm the existence of the air conditioning units 1 and 4, and display the response results from the air conditioning units 1 and 4.
In particular, when the setting attribute and the installation attribute are different from each other, this is displayed. Therefore, it is possible to accurately detect an error in the address value setting during the installation work of the air conditioning units 1 and 4, and it is possible to detect the error in the system configuration. Even if the air conditioning unit, which should not exist, is actually installed, there is an effect that it can be detected.

Upon receiving the above notification, the centralized control device 11 stores it as the state of the first air conditioning group 9.
Then, the second transmission means 33 triggers the notification from the master unit to all the air conditioning units 4 which are slave units, and sends an air conditioner operation setting command “air conditioner operation setting, child, stop, heating,
20 ° C. ”, that is,“ 2D 00 00 01 14 ”is transmitted. The air conditioning unit 4 continues to operate with the current settings until it receives the settings next time.

In this way, the air conditioning unit 1 set as the master unit reports the current operating state to the central control unit 11 at a predetermined time interval, and the central control unit 11 selects the units other than the air conditioning unit 1 based on the above report. Since the operation content is sent again to the air conditioning unit 4, if the operation content is different from other air conditioning units in the group due to communication error,
There is an effect that the processing load of the centralized control device 11 for correcting this can be reduced.

Fourth Embodiment 12 to 14 are views showing an embodiment of the sixth invention of the present invention, FIG. 12 is a functional configuration diagram, FIG. 13 is a communication command diagram, FIG. 14 is a communication sequence explanatory diagram, and FIG. Is a function setting reading communication sequence, FIG. 14B is a function setting restoring communication sequence, and the same reference numerals indicate the same parts. FIG. 2 is also used in the fourth embodiment.

In FIG. 12, 41 is an air conditioning unit 1.
Function setting monitor request means connected to (the same applies to the air conditioning unit 4) and monitoring the contents of those function settings, 42 is connected to the air conditioning unit 1, and a first non-volatile storage means for storing the response from the air conditioning unit 1 in a non-volatile manner. , 43 are connected to the first non-volatile storage means 42 and the air conditioning unit 1, and function setting transmission means for transmitting the stored contents, and 44 are connected to the air conditioning unit 1, and non-volatilely store the transmitted function setting contents. It is a non-volatile storage means.

Next, the operation of this embodiment will be described with reference to FIGS. 13 and 14. As shown in FIG. 13, the communication command includes a function setting (01 2D), a function setting monitor request (21 2D), and a function setting monitor response (21 AD).
And the command of the attribute, function number and setting contents of the air conditioning unit. Here, the air conditioning unit 1 has an attribute that is uniquely determined for each type, and the number of settable functions is different. For example, an air handling unit with an attribute of AH can set 57 items.

A function setting reading sequence (see FIG. 14)
(A)) First, the clerk operates a switch provided on the control board of the air conditioning unit 1 itself to perform initial setting and function setting of the air conditioning unit 1 and turn on the power. The air conditioning unit 1
The function setting is read from the switch and stored in a nonvolatile manner. When the clerk operates the switch provided on the substrate of the centralized control device 11 to set the centralized control device 11 to the initial setting and function setting capture mode of the air conditioning unit 1, the function setting monitor request means 41 causes the function setting monitor request command. (212D) is transmitted to the air conditioning unit 1.

When the air conditioning unit 1 receives the above command, it sends a function setting monitor response command (21 AD) to the centralized control device 11. In FIG. 14, when the attribute of the air conditioning unit 1 is AH, the function settings of function numbers 1 to 57 are transmitted. Then, the centralized control device 11 nonvolatilely stores these function setting values in the first nonvolatile storage means 42.

Then, the function setting transmission means 43 of the centralized control device 11 transmits a function setting command (01 2D) to the air conditioning unit 1. At that time, a switch on the control board of the centralized control device 11 is operated to set the centralized control device 11 to a mode in which the initial setting and the function setting of the air conditioning unit 1 are not taken in.

The air conditioning unit 1 nonvolatilely stores the transmitted function setting value in the second nonvolatile memory means 44. In this way, the communication command causes the air conditioning unit 1 and the centralized control device 11 to share the initial setting and the function setting of the air conditioning unit 1 which are non-volatilely stored in the air conditioning unit 1 with each other. There is an effect that the function setting of the air conditioning unit 1 can be automatically restored in the initial communication with the centralized control device 11 without operating all the switches on the board, such as when the board is replaced.
