2. Description of the Related Art FIG. 1 is a block diagram showing a conventional relatively large-scale building management apparatus (note that FIG. 1 is also used in an embodiment of the present invention). In the figure, (1) is a central monitoring device that manages the entire building, which is connected to the host network (2).
Multiple distributed control units (3A) are connected to this host network (2).
~ (3N) is connected.

The distributed control devices (3A) to (3N) are the upper transmission processing unit (4) connected to the upper network (2) and the upper transmission processing unit.
It is composed of a control arithmetic unit (5) connected to (4), a lower transmission processing unit (6) connected to the control arithmetic unit (5), and a database (7). (8A) to (8N) are distributed control devices (3A) to (3N) via the lower network connected to the lower transmission processing unit (6).
Equipment controller connected to, (9A) ~ (9N) is equipment controller (8A)
It is equipment such as lighting, electric power, and air conditioning in the building connected to ~ (8N).

The conventional building management system is constructed as described above, and each of the distributed control systems (3A) to (3N) corresponds to a central monitoring system in a small-to-medium-sized building management system. Central monitoring device
(1) is a distributed control device (3A) through the upper network (2)
(3N) to send control data, further lower equipment controller (8A)
Sending data to ~ (8N). And each equipment controller
(8A) to (8N) control terminal building facilities (9A) to (9N).
As described above, in a relatively large-scale building management system, it is common to have a decentralized building system configuration with the above hierarchical structure.

In the central monitoring device (1), a table is set so that information on the number of terminal equipments and management points of 5,000 to tens of thousands can be managed, and the equipments (9A) to (9N) can be controlled at a certain time. ON / OFF schedule control, event control to control equipment (9A) to (9N) in synchronization with changes in input signal, group control to control multiple equipment (9A) to (9N) in groups The central monitoring device (1)
A) to (9N) are processed in units of one point, and control signals in units of equipment (9A) to (9N) are transmitted to the distributed control devices (3A) to (3N).

If the central monitoring device (1) should go down, the control computing unit (5) of the distributed control devices (3A) to (3N) searches the database (7), and the equipment (9A) )-(9N) schedule control is executed independently to enable low-level independent control.

[0007]

In the conventional building management system as described above, the central monitoring system (1) has the facilities (9A) to (9N) 1.
Since the calculation processing is performed up to the point unit, the larger the building management device becomes, the larger the calculation processing amount of the central monitoring device (1) and the higher the frequency of use of the upper network (2). Therefore, the performance of the central monitoring device (1) and the transmission capacity of the upper network (2) will affect the performance improvement of the entire system, and the costs of the central monitoring device (1) and the upper network (2) will be significant. There is a problem that it tends to be high.

If the central monitoring device (1) goes down,
Since all the functions except the schedule control do not work, there is a problem that risk dispersion cannot be achieved sufficiently.

The present invention has been made to solve the above-mentioned problems, and it is possible to reduce the cost of the central monitoring device and the host network and to achieve a high level of self-sustaining distribution even when the central monitoring device is down. An object is to provide a building management device.

[0010]

The building management apparatus according to the first aspect of the present invention is a computing means for executing event control, group control, etc. of each facility if the data transmitted from the central monitoring apparatus is aggregated information.

【Example】

Example 1. 1 and 2 are views showing an embodiment of the first invention of the present invention, FIG. 1 is a block diagram, and FIG. 2 is an operation flowchart of a control arithmetic unit. Although the configuration of FIG. 1 is the same as that of the conventional device, the functions of the control operation unit (5) and the database (7) of the distributed control devices (3A) to (3N) are improved.

Next, the operation of this embodiment will be described with reference to FIG. Wait for receiving data from the host network (2) in step S1, and if so, proceed to step S2,
The received data is used for equipment such as group control and event control (9
Judge whether the information is related to the control of A) to (9N). If the information is related to equipment control, the process proceeds to step S3, and equipment (9A) to (3N) managed by the corresponding distributed control unit (hereinafter referred to as MU) (9)
Database (7) as to whether there are facilities to be controlled in (A) to (9N)
If there is equipment (9A) to (9N) to be controlled, proceed to step S4 and install equipment (9A) to (9A) through the lower network.
Control (9N). If there are no facilities (9A) to (9N) to control, the process returns to step S1.

Here, steps S3 and S4 constitute an arithmetic means. If it is determined in step S2 that the information is not related to equipment control, the process proceeds to step S5, and MU (3A) to (3N)
If it is the information for changing the program or the like of the control calculation unit (5), the process proceeds to step S6, the program or the like of the control calculation unit (5) is changed according to the information, and the process returns to step S1. Here, steps S5 and S6 constitute a management means.

As described above, the conventional central monitoring device (1)
(9A) to (9N) The control is performed for each point, but since the distributed control devices (3A) to (3N) judge and control only by giving the aggregated information, the central monitoring device (1) The amount of data to send is reduced. Therefore, it is possible to reduce the calculation processing amount of the central monitoring device (1) and reduce the transmission frequency of the upper network (2). Therefore, the central monitoring device
Since the load on (1) and the host network (2) is reduced, the performance of the entire system is improved, especially in a large-scale building system.

In addition, from the central monitoring device (1) to the distributed control device
Since the program of (3A) ~ (3N) can be changed,
While increasing the self-sustaining dispersion function of the decentralized control devices (3A) to (3N),
Similar to the conventional device, the fine control function from the central monitoring device (1) is not lost.

Example 2. FIG. 3 is a block diagram showing another embodiment of the first invention of the present invention, and the same reference numerals as those in FIG. 1 indicate the same parts. 2 is also used in the second embodiment. This embodiment uses a private branch exchange (PBX) (15) in a building, while the higher level network (2) in FIG. 1 is a dedicated local area network (LAN). ) To (3N), the operation of the control calculation unit (5) is the same as in the first embodiment. In FIG. 3, since the private branch exchange (15) is used, it means that an extension line is used, but it is obvious that an outside line (subscription line) may be used.

Thus, by using the telephone line for the upper network (2), the wiring cost can be reduced and the expandability can be improved. Further, as described in the first embodiment, since the transmission load of the upper network (2) is reduced, even if a telephone line with a slow communication speed is used, the performance of the entire system will not be impaired.

Example 3. FIG. 4 is an operation flowchart of the control calculation section showing an embodiment of the second aspect of the invention.
1 and 3 are also used in the third embodiment. Step
Steps S1 to S6 are the same as in the first embodiment. If it is determined in step S1 that the data has not been received, the process proceeds to step S7 and it is determined whether or not the state change of the equipment (9A) to (9N) has occurred.
Here, the occurrence of a state change of equipment means, for example, a fire occurrence,
Refers to the occurrence of intrusion. Then, when it is determined that the state changes of the facilities (9A) to (9N) occur, the process proceeds to step S8.

In step S8, the corresponding MU (for example, MU
Other than MU (3A)), it is determined whether an event or the like to be transmitted to other MUs (3B) to (3N) occurs, and if so, the process proceeds to step S9, and other MUs (3B) to (3B) Information such as an event is transmitted to 3N) and the process proceeds to step S10. Also, when it is determined in step S8 that an event or the like to be transmitted to other MUs (3B) to (3N) does not occur, the process proceeds to step S10. In step S10, it is determined whether the conditions such as the events (9A) to (9N) of the facilities (9A) to (9N) managed by the corresponding MU (3A) are satisfied. If it is determined that the conditions are satisfied, the process proceeds to step S4 and the facilities ( 9A) to (9N) are controlled.

Here, step S7 constitutes a judgment means, and steps S8 and S9 constitute a control means. Like this, MU
Since it is possible to send event information between (3A) ~ (3N), even if the central monitoring unit (1) goes down, it does not affect the system function, and MU (3A) ~ ( 3N) enables highly independent decentralized control.

[0026]

As described above, according to the first aspect of the present invention, if the data transmitted from the central monitoring device is the aggregated information, the event control of each facility, the group control, etc. are executed, and if it is the change information. Since the program is changed, the distributed control device can operate by transmitting the aggregated information, the amount of data transmitted by the central monitoring device is reduced, the amount of calculation processing of the central monitoring device is reduced, and It is possible to reduce the transmission frequency of the network, and particularly to improve the performance of the entire large-scale building management system.

Further, since the program of the distributed control device can be changed from the central monitoring device, the fine control function from the central monitoring device is lost as in the conventional device while enhancing the self-sustained distribution function of the distributed control device. There is an effect that can be prevented.

Further, in the second aspect of the invention, when it is judged that the change in the state of the equipment is an event or the like, it is controlled to which distributed control device this is sent, and if the change information is sent from the central monitoring device. Since the above judgment and control programs are changed, it becomes possible to transmit event information between distributed control devices, and even if the central monitoring device goes down, it affects system functions. Without
There is an effect that it is possible to realize a high degree of independent distributed control of the distributed control device.

Further, in the third aspect of the invention, if the data transmitted from the central monitoring unit is aggregated information, event control of each facility, group control, etc. are executed, and a change in the state of the facility is judged to be an event or the like. Then, which distributed control device is to be sent is controlled, and when the central monitoring device sends the change information, the judgment and control programs and the like are changed, so that the aggregate information is sent. If so, the distributed control device can operate, the amount of data transmitted by the central monitoring device is reduced, it becomes possible to change the program of the distributed control device from the central processing device, and it becomes possible to transmit event information between the distributed control devices. It has the same effect as the first and second inventions.
