The integrated monitoring system 50 includes the function-specific sub-control systems 52, 54, 56, 5 provided separately for each function.
8 Monitor and control the whole.

By providing a single control system for integrating and controlling all areas for each function, the number of control systems required for the entire building can be reduced.

[Problems to be solved by the invention]

However, in a conventional building management system, for example, when a large number of people gather in a certain conference room, after the temperature actually rises, this is sensed, and then an operation of returning to the original temperature is performed, so that a certain temperature is reduced. Control is performed so as to maintain it. In such control, it takes a long time to return to the original temperature after the temperature changes, and it is inevitable that the response to the change in the situation is delayed. As described above, there is a problem in that a control system for each function has a limit in capability, and it is difficult to improve the performance of the control system and perform fine control.

Further, if the control system which is the center of each function is concentrated in one place as in the conventional building management system, if the control system of a certain function goes down, the function of the whole building stops. Moreover, in the case of the configuration as shown in FIG. 3, the communication means for connecting each control system and each area is very complicated, and is usually wired through the same communication cable duct. For this reason, there is a problem that the reliability of the building management system largely depends on the communication means, and if an accident such as disconnection occurs in one place of the communication means, the entire building is affected.

Furthermore, when a partition on a certain floor has to be changed, such as when a tenant in a part of the building is replaced, the control system that controls the entire building must be changed each time. However, there is a problem that the work for that is complicated.

The present invention has been made based on the above circumstances, and in addition to finely managing and controlling various facilities of a building, dispersing a risk of a functional stop due to a failure of a control means, and further changing a partition of an area. It is an object of the present invention to provide a building management system that can easily change control means accordingly.

[Means for solving the problem]

The present invention for achieving the above object divides the entire building into predetermined areas and independently controls at least the air-conditioning equipment, security equipment and environmental equipment in the area for each area. A building management system having a plurality of means, a plurality of the area control means, a communication means for performing communication with the general control means for controlling the plurality of the area control means collectively and the other area control means, Air conditioning equipment in the area,
First control means for performing the control or management in association with at least two of security equipment and environmental equipment, and second control means for performing the control or management in association with another area control means via the communication means Wherein a disaster prevention facility independent of the area control means is provided for each of the areas, and the disaster prevention facilities in each of the areas are comprehensively controlled in the entire building.

Further, the one area may correspond to the entire space of one floor or a space obtained by further dividing one floor.

Further, the air conditioning equipment controls temperature, humidity, oxygen concentration and carbon dioxide gas concentration, the security equipment controls entrance / exit and monitors illegal entry, and the environmental equipment controls incense, lighting and sound, The disaster prevention equipment may monitor fires, gas leaks and smoke emission.

[Action]

According to the present invention, with the above configuration, the area control means performs control not for the entire building but for each area obtained by dividing the space of the entire building into predetermined units. In addition, the control target is not only a single function, but also controls the air-conditioning equipment, security equipment and environmental equipment in an integrated manner. For this reason, since the area control means of each area operates independently of the area control means of another area, even if the area control means of a certain area fails, its influence does not reach other areas. Therefore, the danger of a failure / stop of the control system of the whole building is dispersed. In addition, since a plurality of functions and equipment are controlled by one area control unit, it is easy to control different functions in association with each other. Disaster prevention equipment is also provided for each area, but its control is performed comprehensively for the entire building independently of the area control means.

By providing a comprehensive control means for controlling a plurality of area control means collectively, each area is centrally managed, information is centralized and shared. It is possible to perform control in which areas are mutually associated.

In addition, by setting one area as a space of one whole floor or a space obtained by further dividing one floor, the area control means controls various facilities for each floor or each space obtained by further dividing one floor.

Furthermore, the air-conditioning equipment controls the temperature, humidity, oxygen concentration and carbon dioxide concentration, the security equipment controls the entrance and exit, and monitors the illegal entry, and the environmental equipment adjusts the fragrance, lighting and sound, and the security equipment By monitoring fires, gas leaks and smoke emissions, various functions can be associated with one another and finely controlled. For example, it is easy to predictively control the temperature of a specific area when the number of persons in a specific area increases by associating the security management facility entrance / exit management with the temperature control of the air conditioning equipment.

〔Example〕

Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 is a system block diagram schematically showing an overall configuration of a building (building) management system according to an embodiment of the present invention, and FIG. 2 is a functional block diagram thereof.

Z ₁ to Z _n is a region obtained by dividing the entire building in a space of a predetermined unit (zone) in the first view. In the present embodiment, the zone is divided by using each floor of the building as a unit. However, in general, a plurality of rooms on each floor may be used as one unit, and furthermore, a method of dividing these rooms in one building May be mixed.

Integrated Management Controller X ₁ to X _n is the zone control means provided for each zone divided as described above to control the various equipment other than the disaster prevention facilities independently for each zone. The control of the integrated management controller is performed digitally. That is, for example, when controlling the flow of water flowing through the air conditioning equipment, an analog signal indicating the flow rate is output
After the A / D conversion, a predetermined process is performed, and the control signal obtained by this is converted back to an analog signal by the D / A conversion and supplied to the flow rate adjusting mechanism.

The integrated monitoring and control system 2 serving as the integrated control means is connected to the integrated management controller X of each zone by the communication means 8 and can know in real time what state each zone is in. Information can be centralized. Further, information common to each integrated management controller X can be shared, and unnecessary duplication of information can be eliminated. Further, it controls the scheduling of the integrated management controller of each zone. This comprehensive monitoring and control system 2 can manage not only one entire building but also a plurality of related buildings.

As shown in FIG. 2, one integrated management controller (corresponding to X1 to _Xn shown in FIG. ₁ ) integrally controls the air conditioning equipment 12, the security equipment 14, and the environmental equipment 16. The air conditioner 12 adjusts temperature, humidity, oxygen concentration and carbon dioxide concentration by a blower 20 and a harmony device 22, and the security device 14 is an optical ID system 24,
The electronic lock 26 and the security sensor 28 control entry / exit and monitor illegal intrusion.
Adjust lighting, sound, fragrance, etc. by 32 others. The integrated management controller X also controls a blind controller 34 that adjusts the incidence of light from outside by changing the angle of the wings of the blind according to the time.

There is a demand that the disaster prevention equipment 18 must be installed independently of other equipment from the viewpoint of ensuring the reliability of operation and the like. For this reason, in this embodiment, disaster prevention equipment is provided for each zone.
The management is comprehensively performed by the integrated monitoring and control system 2 through the control means 6 dedicated to disaster prevention equipment.

The integrated management controller X is connected not only to the integrated monitoring and control system 2 but also to the integrated management controller X of another zone by the communication means 8 and is connected by digital communication. This makes it possible to easily control each integrated management controller X in association with another integrated management controller X. Since the communication means 8 uses a protocol whose protocol is disclosed (American Automatrix Co., Ltd.), the integrated management controller X
It is not always necessary to use the same model, so if any existing model is used and programming is performed to match the above protocol, communication between different models is possible, and the flexibility of the entire building management system The nature increases. In addition, even if the communication means is disconnected, the control function of each zone continues to operate without stopping, so that the degree of reliability of the building management system depends on the communication means 8 is reduced.

In the building management system according to the present embodiment, since the integrated management controller provided in each zone independently controls and manages various facilities, it is easy to control and manage different facilities in association with each other. For example,
The air conditioning equipment 12 and the security equipment 14 are associated with each other, and the optical ID system 24 recognizes that a large number of people have gathered in a certain conference room, and performs temperature control in a predictive manner to optimize the conference room quickly. Temperature. In addition, the lighting device 30 and the optical ID system 24 can be associated with each other so that an operation of automatically turning off the lighting when all the people have left the room is possible. If such a thing is to be performed by a conventional building management system, the load on the control system of each function for managing the entire building becomes excessively large, which is practically impossible.

In the building management system according to the present embodiment, by providing an integrated management controller for each zone, the risk of stopping the functions of the entire building is dispersed. That is, even if the integrated management controller in a certain zone fails,
The cause of the failure does not extend to other zones, and the effect of the damage can be limited to that zone.

Also, in the building management system in this embodiment, by independently programming the integrated management controller of each zone, it is not necessary to operate each facility uniformly in the whole building, but it is necessary for the zone. Special actions can be taken. For example, even in the same building, the sunshine varies depending on the direction of the window and the surrounding environment, so that the air conditioner can be controlled to operate optimally for each zone in accordance with the difference. In addition, even if tenants enter and exit after building construction, and the layout and partitions in the zone are changed, the desired control can be easily performed by programming the integrated management controller. There is no need to consider.

In the above embodiment, the case where the general control means is provided is described. However, for example, when the number of the zone control means is small, the general control means may not be provided.

〔The invention's effect〕

As described above, according to the present invention, by providing control means for each area and controlling various facilities independently for each area, it is possible to perform fine control by relating different facilities in one area to each other. It is possible to provide a building management system and a building management apparatus that can perform the improvement and improve the living environment in the building. Also, even if the control means in a certain area fails, the range affected by the failure is limited to that area, the danger of the function stoppage of the entire building can be dispersed, and furthermore, the arrangement and partitions in the area are changed In addition, it is possible to provide a building management system and a building management apparatus that can easily change the control of the area by independently performing programming.
