A plurality of equipment processing devices 3 are provided, and each equipment processing device 3 is connected with a disaster prevention sensor 4 assigned to itself. Also, a plurality of local processing devices 2 are provided,
Each local processing device 2 is connected to a facility processing device 3 assigned to itself. The central processing unit 1 is connected to each local processing unit 2. The display device 5 is connected to the central processing unit 1. FIG. 7 is a block diagram showing the internal configuration of the equipment processing device 3, and the host input / output processing device 3a.
The data management device 3b and the lower-level input / output processing device 3c are provided. In the building management system configured as described above, each facility processing device 3 collects individual data from the disaster prevention sensor 4 assigned to itself through the lower-order input / output processing device 3c and holds it in the data management device 3b. . Further, each local processing device 2 collects and holds the individual data held in the facility processing device 3 assigned to itself. Then, the individual data held in each local processing device 2 is collected and held by the central processing device 1, and is CRT-displayed or printed by the display device 5 as necessary.

[0003]

However, according to such a conventional building management system, the central processing unit 1
Further, since the local processing device 2 holds the individual data of a large number of disaster prevention sensors 4, there is a problem that the load related to data communication is high and the storage capacity is excessively required.

[0004]

The present invention has been made in order to solve such a problem, and collects individual data from scattered sensors, and collects the individual data for each predetermined area. A plurality of equipment processing means that aggregates and collects aggregate data, a plurality of local processing means that collects and holds aggregated data from equipment processing means that is assigned to itself, and collects and holds aggregated data held by these local processing means Central processing means for

[0005]

According to the present invention, therefore, the individual data from the sensor is collected by each facility processing means as the aggregated data for each predetermined area, and the individual processing means aggregates from each facility processing means assigned to itself. Data is collected and retained,
The central processing means collects and holds the aggregated data held by each local processing means. Further, according to the present invention, if the individual data from the sensor is collected and held by each facility processing means, the individual data of the sensor can be collected as necessary in the central processing means via the local processing means. It can also be read out and displays both aggregated data and individual data.
Control is also possible.

EXAMPLES The facility management system according to the present invention will be described in detail below.

FIG. 1 is a system configuration diagram of a building management system showing an embodiment of the present invention. In this embodiment, an equipment processing device 3'is used instead of the equipment processing device 3 shown in FIG.

FIG. 2 is a block diagram showing the internal structure of the equipment processing device 3 ', which comprises an integrated processing device 3d in addition to the upper input / output processing device 3a, the data management device 3b, and the lower input / output processing device 3c. There is.

The operation of the building management system will be described below with the functions of the integrated processing device 3d.

Each equipment processing device 3'collects individual data from the disaster prevention sensor 4 assigned to itself through the lower order input / output processing device 3c and holds it in the data management device 3b.

Each facility processing device 3'receives the disaster prevention sensor data output request from the local processing device 2 ', and collects the individual data held in the data management device 3b for each predetermined area in the aggregation processing device 3d. To output aggregated data via the upper input / output processing device 3a.

Each local processing device 2'collects the aggregated data from the facility processing device 3'assigned to itself, that is, the aggregated data from each facility processing device 3'in response to the output request of the disaster prevention sensor data. Hold.

The centralized data held in each local processing device 2'is collected and held by the central processing device 1 ', and is displayed on the display device 5 as a CRT or printed as required.

As a method of collecting individual data in the central processing unit 3d, in the present embodiment, individual data of the state and alarm of each disaster prevention sensor 4 is collected for each disaster prevention area, and one data area is included as a warning area. It is used as consolidated data of status and alarm.

In this embodiment, the aggregate data is transmitted from the facility processing device 3'to the local processing device 2'in the transmission format as shown in FIG. That is, the warning area number is assigned to # 1, the warning area status is assigned to # 2, the sensor number that caused the change in the status and the alarm is assigned to # 3, and these are sent as aggregated data. By transmitting this aggregated data, it is possible to know the sensor number in which the state and the alarm have changed, and it is possible to obtain the same function as in the conventional case where the central processing unit 1 and the local processing unit 2 hold individual data. .

Further, in this building management system, when the facility processing device 3'receives an individual data output request from the central processing device 1'via the local processing device 2 ', it is held by the data management device 3b. The individual data stored therein is transmitted to the central processing unit 1'via the local processing unit 2 '. This transmission of individual data is performed in the transmission format as shown in FIG. 4, and the number of each sensor and the state of the sensor are transmitted as a pair in the unit of integrated disaster prevention warning area in the aggregation processing device 3d. By transmitting this individual data, the state of each sensor can be known on the display device 5 as needed.

That is, according to this embodiment, since the facility processing device 3'holds the individual data which is not normally required, it can be read out from the central processing unit 1'when necessary, and the individual data can be read. It is possible to obtain the same function as in the conventional case in which the CPU is held by the central processing unit 1 and the local processing unit 2.

Further, in this building management system, the control data from the central processing unit 1'is sent to the facility processing unit 3'via the local processing unit 2 '. In this case, the central processing unit 1 ′ transmits control data for required aggregated data based on the retained aggregated data.
Further, the central processing unit 1'sucks the individual data from the facility processing unit 3 ', and transmits the control data for the designated individual data based on the data. This control data is transmitted in the transmission format shown in FIG.

That is, according to the present embodiment, the individual data is collected from the facility processing device 3'as needed, and the individual data is transmitted from the central processing device 1'by designating the individual data and transmitting the control data. The same function as that of the conventional case held by the central processing unit 1 can be obtained.

[0020]

As is apparent from the above description, according to the present invention, individual equipment processing means aggregates individual data from the sensors into predetermined areas to obtain aggregated data, and each local processing means performs self-assembling. Since the centralized processing means collects and holds the aggregated data from each equipment processing means assigned to the central processing means, the centralized processing means collects and holds the aggregated data held by each local processing means. , The load related to data communication is reduced, and the storage capacity is reduced, and the individual data from the sensor can be managed with the same function as the conventional one.
