Building management system

The innovation relates to a building management system according to the generic term of protection claim 1.

Known systems include locking or access control systems, fire alarm systems, burglar alarm systems for buildings, etc., each with a display panel, although these known systems only cover certain, system-typical individual functions.

The aim of the innovation is to demonstrate a building management system that makes it possible to link the individual functions of a large number of system components in a meaningful way to ensure optimal security and monitoring of a building and to combine the various system components in a common panel technology.

To solve this problem, a building management system is designed according to claim 1. Further developments of this system are the subject of the subclaims.

In the new system, the system components are at least partially devices or subsystems that work independently with regard to their system-typical functions, but are combined and linked to one another via the central control and monitoring unit of the building management system in the common panel technology, so that the system components, in addition to their system-typical functions, also send messages to the central control and monitoring unit of the building management system, which are used for displays on the common panel technology. The central control and monitoring unit also automatically initiates the corresponding measures stored in the central control and monitoring unit or in the program installed there based on the incoming messages. But also

Measures can be initiated by manual input on the control and display panel, in particular taking into account the messages displayed on the display panel, which are messages from various system components and/or were generated from the messages from various system components.

The innovation is explained in more detail below using the figures of an example. They show:

Fig. 1 shows a simplified functional or block diagram of the

building management system according to the innovation; Fig. 2 in simplified representation and in block diagram of display and control panels connected to a bus (data and address bus);

The building management system shown in Figure 1 comprises a computer 1, for example a PC, as the central control and monitoring unit, which is used, among other things, to monitor and control various system components using a special program installed on this PC. Furthermore, the computer 1 also enables changes or interventions in the program, changes to the functional sequences and programming of individual or all system elements, etc., and, via the associated screen 3, also enables, among other things, visualization and monitoring of individual system components and/or the messages received from these system components on the computer 1, etc.

In the embodiment shown, the following system elements are assigned to the computer λ:

- Burglar alarm system 4;

- Escape route security 5;

- Device 6 for automatically sending SMS messages to certain mobile phones;

- locking system 7;

- Smoke and heat extraction system 8;

- Control and display panel 9;

- video surveillance device or system 10;

- Access control 11;

- Fire alarm system 12.

Of course, individual system components can be omitted if they are not required, or individual system components can be provided multiple times.

The building management system is designed to be flexible, in particular in such a way that individual system components can be removed from the building management system or newly integrated into this system if necessary, by installation via the central computer 1.

The system components 4-12 are connected to each other and to the central computer 1 via a bus 13, to which the individual system components are connected via corresponding interfaces or input and output modules.

Individual system components in turn form fully functional subsystems that carry out the function assigned to them autonomously, for example based on their own sensors, although the functions of such autonomously operating system components can also be controlled from the central computer 1. The current status and any alarm are transmitted from these system components to the central computer 1 and displayed there on the screen 3, among other things. The connection between the central computer 1 and the aforementioned system components 4-12 via the bus 13 is bidirectional, i.e. data (status data, alarms, etc.) can be transmitted from the system components to the computer and data (for example queries, commands, program changes, etc.) can be transmitted to the system components via this bus connection.

An example of an autonomously operating system component is the hold-open system 7, whose task is to keep smoke and fire doors within a building between different building sections open in the normal state or during normal operation and to close them automatically in the event of a fire, but also to enable manual closing and, in addition, to send an acoustic and/or optical alarm signal in the area of the respective smoke and fire doors in order to prevent or delay the spread of smoke and fire by closing the smoke and fire doors and to secure escape routes. The hold-open system 7 has its own fire and smoke detectors, its own fire alarm control panel, smoke protection switches, manual release devices, door holding magnets, door closers, etc. for these system-typical functions, whereby several smoke and fire doors can also be controlled with one hold-open system. The alarm triggered by the hold-open system 7 is fed to the central computer 1 via the bus connection 13, which displays the alarm on the screen 3. Further measures can then be initiated via the computer.

Another autonomously operating system component is the smoke and heat extraction system 8, whose main task is to remove smoke and heat from a building in an emergency and to create as clear a view as possible in order to facilitate fire fighting and to keep rescue and escape routes free of smoke and gases. Furthermore, the smoke and heat extraction system 8 can also be used for ventilation during normal operation or under normal conditions. Accordingly, exhaust air openings in the building, such as windows, skylights, etc., are assigned to the smoke and extraction system, which are operated via a drive based on the sensor signals assigned to the smoke and heat extraction system or remotely controlled via the central computer 1. Key components of this smoke and heat extraction system are, for example, fire, smoke and heat detectors, fire buttons, drives for opening and closing the exhaust air openings, such as windows, skylights, etc., as well as a smoke and heat extraction system control center to which the system's own components of the smoke and heat extraction system are connected.

and heat extraction system and which also interacts with bus 13.

A largely autonomous system component is, for example, the video surveillance 10, which in addition to video cameras installed in areas to be monitored, has, among other things, a device for storing and evaluating the video images, wherein the evaluation of the video images is carried out, for example, in such a way that an alarm and a message to the central computer 1 only occur when the image content of an image recorded by a video camera changes overall or in a specially monitored area.

Another autonomously operating system component is, for example, access control 11, the task of which is, among other things, to secure external and internal doors of buildings according to risk classes, to demarcate operational areas and to limit access authorizations locally and temporally, whereby the respective person is identified, for example, by using a key, a card, a transponder and/or by entering a secret code and access is granted if access is authorized, while conversely access by unauthorized persons is prevented and an appropriate alarm is triggered. For these functions, access control 11 contains, for example, electronic and electromagnetic locking devices or locking cylinders on the monitored doors, door locks with door openers and electronic keys, electrically connectable locks, readers for electronic cards or keys, receivers for transponders, for example electronic cylinders with transponder receivers, etc. Not only doors, but also other areas or barriers, for example barriers, elevators, roller shutters, lighting can be controlled and/or linked with access control 11.

The burglar alarm system 4, which is also a functional system in itself, essentially consists of the actual alarm system and the sensors connected to it, for example for window, door and/or room monitoring.

The escape route security system 5 is designed in such a way that escape doors and emergency exits can be opened manually or centrally controlled without any tools in an emergency, but on the other hand, in the event of misuse, i.e. an unauthorized attempt to open, an alarm is triggered and transmitted to the central computer 1. System-specific components of the escape route security system 5 include, for example, panic locks, escape door locks, door contacts, holding magnets, escape door openers, key switches, door terminals, central and decentralized door controls, optical and acoustic alarms, mechanical and electronic access controls.

The control and display panel designated 9 in Figure 1 is constructed in a modular manner as shown in Figure 2 and is connected to the bus 13 via an input and output module 14. The control and display panel 9 also consists of at least one control module 9a and one display module 9b. These modules are each connected to corresponding connections of the input and output module 14. Instead of the display module, relay modules 15 can also be connected to the input and output module 14, which are then used to remotely control certain functions via the bus 13. Furthermore, as is also indicated in Figure 2, it is possible to control a site plan module 16 via the input and output module 14, with which the location of an alarm is displayed, for example. It is also possible to form an autonomous unit that is spatially further away from the central computer 1 (e.g. several kilometers) with at least one input and output module 14 and a tableau microprocessor module 17 and associated operating modules 9a, display modules 9b, relay modules 15 and/or site plan modules 16, which is then connected to the bus 13 or the central computer 1 via the tableau CPU module 17 and a data connection, for example CAN bus 18 and an interface not shown.

Certain messages or alarms can thus be displayed on the control and display panel 9 or on the display modules 9b therein, controlled by the program stored on the central computer 1, if necessary also with the

A19939.DOC J JJ,

Location of the respective alarm on the site plan panel 16. Furthermore, certain measures defined by the program can be initiated manually via the control and display panel 9 or its control module 9a.

However, the system described not only allows the visualization of certain messages on the screen 3 and on the respective control and display panel and the manual initiation of certain functions, but also the central computer initiates functions associated with certain messages.

For example, if the burglar alarm system 4 triggers an alarm, the following functions are triggered:

- Sending a message via the SMS reporting system 6,

- Connecting a video image from the video surveillance 10 to the screen 3 or to the user interface there;

- Display on an associated display panel 9;

- Locking of all doors controlled by access control 11;

- Closing all building openings (windows, etc.) controlled by the smoke and heat extraction system and

- Closing of all doors held by hold-open systems 7.

For example, if the fire alarm system 12 is triggered, the following measures are initiated:

- Sending a message via the SMS reporting system 6;

- Activation of all escape doors of the escape route security system 5;

- Message on a display panel 9;

- Closing of all doors held by hold-open systems 7 and

- if necessary, opening of building openings controlled by smoke and heat extraction systems.

If an access control alarm 11 is triggered, for example by using a locked key, a locked access card, a locked transponder, etc., the following measures are triggered:

- Notification via SMS reporting system;

- message on a display panel 9; and

- Connecting a video image from the video surveillance 10 to the screen 3 or to the user interface there.

If the smoke and heat extraction system 8 triggers an alarm, the following measures are initiated:

- Sending a message via the SMS reporting system;

- Message on a display panel 9;

- Control of the assigned hold-open system to close the corresponding smoke and fire doors; and

- Activation of the assigned escape doors via the escape route security

If an alarm is triggered by the hold-open system 7, for example by a smoke or fire alarm there, the following functions are initiated:

- Closing of the corresponding doors of the locking system 7 in the corresponding building area;

- Sending a message via the SMS reporting system;

- Activation of the assigned escape doors via the escape route security system 5;

- Message on a tableau 9; and

- Connecting a video image from the video surveillance 10 to the screen 3 or to the user interface there.

If the escape route security system 5 is alarmed, for example due to an unauthorized intrusion attempt, the following measures are initiated:

- Sending a message via the SMS reporting system;

- Message on a tableau 9;

- Visual and/or acoustic alarm on site; and

Connecting a video image from the video surveillance 10 to the screen 3 or to the user interface there.
