Description

[0001] The invention relates to a system for controlling a technical system in the field of building automation, wherein the system comprises a technical system with sensors and actuators, as well as a control matrix.

[0002] The technical systems controlled by the proposed system are present in buildings, for example, and control processes in the event of a fire. For use in such a system, it is known in the art for a fire protection expert to create a fire control matrix (BFSM). This BFSM contains all relevant detection zones, for example, the detection zones of the building monitored by fire alarm lines. The fire alarm lines include sensors that can detect a fire and transmit it to a central processing unit. So-called MRA buttons, which preferably operate purely manually, can also be used for triggering. The detection zones are typically recorded on the x-axis of the BFSM.The y-axis of the BFSM is typically used to describe the actions per detection zone for the relevant technical systems or their components, such as doors, smoke dampers, and fans. This then results in specific control commands or actions to be initiated for the individual systems and / or components. Such a command could, for example, be to switch off the ventilation ducts or close special fire doors.

[0003] The disadvantage of using such a BFSM is that this matrix is ​​often very extensive and therefore confusing, especially in complex facilities such as airports, train stations, or large office buildings. This is particularly undesirable in the event of a fire, as a clear representation of the events and the necessary actions that is quickly grasped by the human mind and the corresponding data processing system is desirable in order to be able to act quickly and efficiently with the appropriate resources to prevent or minimize damage to people and material objects.

[0004] The use of an often confusing BFSM can also result in control processes in building automation systems being slowed down and becoming more prone to errors. This can happen, for example, because unnecessarily complex calculations and / or data transmission processes must be performed, or because the complexity of the BFSM leads to incorrect connections being set or implemented.

[0005] So-called programmable logic controllers (PLCs) are also frequently used for plant control. These are often self-monitoring and feature so-called T3 modules, which ensure SIL3 suitability for the corresponding systems and plants. These are devices for regulating and / or controlling technical systems that are programmed digitally. The disadvantage of such conventional PLCs, which are known from the state of the art, is that they are usually programmed in complex programming languages, such as C++, and thus often contain line-oriented programming code that is difficult to understand. This makes the maintenance and operation of a control system or technical plant significantly more difficult, because it requires the availability of IT specialists. This is not always easy in times of skilled labor shortages, especially outside of major cities.In addition, maintaining skilled workers requires considerable financial resources.

[0006] It is therefore an object of the present invention to provide a system for controlling a technical system in the field of building automation that overcomes these disadvantages and deficiencies of the prior art. In particular, a system is to be provided that enables the control processes in a technical building automation system to be made more efficient, faster, and less error-prone. The system to be provided should be so intuitively understandable and easy to operate that it is feasible for non-technical users, eliminating the need for expensive and potentially unavailable specialists, such as IT specialists. Description of the invention:

[0007] The object is achieved by the features of the independent claim. Advantageous embodiments of the invention are described in the dependent claims. According to the invention, a system for controlling a technical installation in the field of building automation is provided, wherein the technical installation comprises sensors and actuators. The system is characterized in that a control matrix can be divided into a first matrix, a second matrix, a third matrix and a fourth matrix, wherein the sensors transmit a subset of first events to the first matrix and the sensors transmit a subset of second events to the second matrix, wherein the third matrix links and / or blocks zones in the building or within the technical installation and a fourth matrix transmits control commands to the actuators.

[0008] It was completely surprising that the proposed system allows control processes and procedures in a building to be optimized and made significantly more efficient. The control matrix can preferably be a fire control matrix (BFSM), whereby a "modified BFSM" is preferably obtained by dividing the conventional control matrix or fire control matrix into preferably four sub-matrices. In particular, the actuators of the technical system can react more quickly to events detected and located by the system's sensors if a modified BFSM is used, which is preferably divided into four sub-matrices. This is particularly advantageous because, especially in building automation systems entrusted with fire protection or smoke extraction tasks, initiating the necessary measures to extinguish a fire or extract smoke from a building is time-critical.

[0009] The term "modified BFSM" is used in the context of the invention preferably for BFSMs obtained by the system and which are more clearly structured than the prior art, and which in particular comprise four sub-matrices, which in the context of the invention are preferably referred to as the "input matrix" or first matrix, the "alarm matrix" or second matrix, the "linking matrix" or third matrix, and the "output matrix" or fourth matrix. The four matrices that preferably form the modified BFSM are preferably referred to as sub-matrices. In the context of the invention, it is particularly preferred that the previously complex BFSM is divided into preferably four separate matrices using the proposed matrix system, wherein the preferably four sub-matrices are connected by the common alarm areas. The alarm areas can preferably be defined or specified by so-called smoke extraction zones and / or smoke extraction systems.It is preferred within the meaning of the invention that the reporting areas are represented on the x-axes of the sub-matrices. The sub-matrices can preferably be formed from tables or data sheets of a spreadsheet program or resemble the operation and external appearance of such tables and data sheets in order to make operation simpler and more intuitive for a user. If the sub-matrices are formed from tables or data sheets of a spreadsheet program and / or resemble them, the proposed system preferably comprises a link between a corresponding software program product and the processing unit so that inputs and changes in the BFSM and / or in the modified BFSM can be converted into actions of the actuators and / or into commands for controlling the actuators. It is particularly preferred within the meaning of the invention that no software is loaded into the BUS modules of a system.Instead, the function of a BUS module preferably arises from the interpretation of a configuration file, with one configuration file preferably being present per BUS module. According to the invention, it is particularly preferred that the configuration file is generated by PC software, in particular using a T3 module.

[0010] It is preferred within the meaning of the invention that the decentralized BUS modules are configured to interpret received control zones. Preferably, the configuration file and firmware located on one or more of the BUS modules form a unit, wherein the interpretation of the received control zones is enabled in particular by this unit. It is preferred within the meaning of the invention that the preferably decentralized, preferably intelligent BUS modules act and / or operate according to their configuration, in particular when the control zones are to deviate from a standby state. It is particularly preferred within the meaning of the invention that the control zones represent a connecting element within the proposed system. They preferably represent an internal reference to databases that can be transmitted to the BUS modules in the configuration file. The transmission of control zones is explained in detail below.It is within the scope of the invention that a smoke extraction system can be an automated smoke extraction system, which, in particular, makes it possible to keep escape and rescue routes free of smoke and to extract smoke from the fire area in a decentralized and autonomous manner upon request. In particular, a smoke extraction system can be used to extract smoke and heat during fires in buildings.

[0011] Preferably, a smoke extraction system can be implemented as an on / off ring bus system with BUS modules. For this purpose, such a system comprises, for example, an automation station, various BUS modules, and at least one ring bus system. This automation station can be used, for example, as a processing unit within the meaning of the invention. It is particularly preferred within the meaning of the invention that a smoke extraction system is designed to prevent the spread of toxic smoke gases in the event of a fire, for example via a building ventilation system. Furthermore, the spread of smoke into neighboring areas, rooms, or buildings can be prevented. Preferably, the smoke extraction system is designed to direct or dissipate smoke and / or heat away from a fire area.

[0012] According to the invention, the automation station is preferably formed by a BUS module with modified hardware. Preferably, a conventional PC device is used, but rather a microcontroller. According to the invention, configuration data can be created which, together with firmware, which is preferably present on one or more of the BUS modules, forms a unit that assigns its task, i.e., functionality, to the respective module.

[0013] According to the invention, it is preferred that the automation station forms the central processing unit in the proposed system. It is preferably configured to perform various safety-relevant tasks, particularly in the area of ​​mechanical smoke extraction in a building. The automation station is preferably configured to monitor and / or control the mechanical smoke extraction in the event of a fire, the smoke extraction and fire dampers, and / or the corresponding systems according to a control matrix, particularly the fire control matrix. Due to the provision of the automation station, the proposed system is particularly capable of activating a corresponding control matrix when smoke extraction from the building is requested by a fire alarm system, an actuating device, and / or the fire department control panel.It is preferred in the sense of the invention that the switching on and off commands stored in the control matrix for system components, such as smoke extraction fans, smoke extraction and / or fire dampers, are forwarded and monitored with the aid of the automation station, wherein the monitoring and control functions can be parameterized by a corresponding matrix.

[0014] The different hardware configuration is preferably manifested in the central processing unit having a key switch. In particular, the control center is not a PC; instead, the central processing unit preferably comprises a specially designed microprocessor. It is within the scope of the invention that the components that make up the proposed system on the hardware side are tailored to the specific requirements of technical building automation, with the circuits, in particular, being optimized for use in building services engineering (TGA) to ensure the longest possible functional integrity in the event of a fire.

[0015] The proposed control device can be configured to control such a smoke extraction system. The smoke extraction system is preferably configured as a ring bus system, whereby this network arrangement, within the meaning of the invention, represents a closed cable route in which the individual network stations are interconnected. The network stations can preferably be formed by bus modules. This network arrangement has the advantage that no network element fails in the event of a short circuit or interruption in the ring line. It is preferred within the meaning of the invention that the ring bus is preferably automatically converted into two branch buses. This advantageously ensures that the network elements remain in operation.

[0016] The ring can, for example, begin in the smoke extraction automation station and can preferably include all bus nodes of the system. The ring bus system preferably ends in the smoke extraction automation station. According to the invention, the bus lines at the smoke extraction automation station are routed as bus outputs to the first bus station and connected there as bus inputs. It is further preferred that the bus stations are preferably connected one after the other. The bus output of the last station is preferably wired as a bus input at the smoke extraction automation station. According to the invention, the ring bus system operates according to an RS 485 protocol in the physical layer. The BUS modules can preferably be used as repeaters in the ring bus system. This advantageously enables bus line lengths of 1200 m between two BUS modules.According to the invention, the length of a bus line is preferably dependent on the transmission speed and / or the data transfer rate. Preferably, the line paths are monitored for breakdowns and / or short circuits.

[0017] It is preferred within the meaning of the invention that hardware components and / or BUS modules can be constructed similarly, identically, or essentially identically. With an identical or essentially identical construction, it may be preferred that different software configurations are used to control the hardware components of the smoke extraction automation station and / or the BUS modules. It is preferred within the meaning of the invention to use control concepts for controlling the system that can be selected from a group comprising individual control, parallel control, and / or multi-control, wherein the individual control can, for example, be active for one scenario, the parallel control for several scenarios, and the multi-control across all systems.

[0018] It is preferred within the meaning of the invention that the scenarios are associated with detection areas, which preferably originate from the fire control matrix, wherein, in the context of the present invention, control zones can be defined, which preferably also originate from the fire control matrix. It is preferred that a control zone can be assigned to a detection area of ​​the fire alarm system. It is further preferred that the control zones, which are preferably associated with the detection areas of the BFSM, are activated by the couplers of the fire alarm system, MRA buttons and / or actions of the fire department at the smoke extraction panel. In other words, this means that activation of a detection area or a control zone can occur, for example, by pressing an MRA button within the fire alarm system. The detection areas are preferably also referred to as control zones within the meaning of the invention.These can be transmitted within the proposed system within the control system, whereby the possibility of transmitting control zones represents a particular merit of the invention. For example, if the proposed control system comprises two bus systems, each with a central processing unit, the control zones can be exchanged between the bus systems using these central processing units. This can be done, for example, using an I2C connection.

[0019] In the sense of the invention, it is preferred that a BUS module represents a hardware device with decentralized intelligence, wherein communication within the system can take place, for example, in a master-slave communication.

[0020] The decentralized intelligence is preferably characterized by the fact that the BUS modules can preferably immediately convert information into concrete action. The information can preferably be transmitted via a bus system. It is preferred that such communication can be reduced to a minimum using a bus system, which advantageously makes it possible to transmit protocols much more quickly. Within the meaning of the invention, it is particularly preferred that the BUS modules are configured to efficiently transmit their status to a central processing device and / or automation station, which is preferably associated with an input matrix.

[0021] According to the invention, it is preferred that the BUS modules are distributed decentrally within the system, in the building services engineering (TGA), and / or throughout the building. This advantageously allows decentralized intelligence to be used to control the system and / or the technical installation. The proposed control system can, for example, comprise the following BUS modules: fire smoke extraction panel, fire alarm system, manual control device, time master, smoke extraction fan, ventilation, fire damper, smoke extraction damper, coupling module, a BUS module for connecting actuators and sensors, and / or a BUS module for integrating messages. According to the invention, it is preferred that the proposed control system can be used to control a technical installation according to the fire zone matrix.If, for example, a fire alarm system triggers and / or is triggered automatically or manually on the manual control device or on the fire smoke extraction panel, the proposed control system, preferably in accordance with the fire zone matrix, controls the fire dampers, the fans and / or the smoke extraction dampers in such a way that any smoke is removed from the building particularly quickly.

[0022] It is preferred in the sense of the invention that the BUS module for integrating messages is designed to trigger locked scenarios, wherein a locked scenario can preferably be triggered directly for each input of the BUS module for different, safety-relevant control tasks, such as mechanical smoke extraction, in the building or in other structures.

[0023] It is preferred in the sense of the invention that the BUS module for controlling and monitoring the preferably motor-operated fire dampers is designed to control preferably up to two fire dampers and their end positions.

[0024] A BUS module for controlling and monitoring smoke extraction dampers can preferably control and / or monitor up to two smoke extraction dampers. It is preferably designed to remove smoke gases and prevent unwanted backflow of smoke gases.

[0025] Furthermore, the proposed system can include a BUS module for controlling and monitoring a smoke extraction fan, as well as its redundancy. The BUS module is particularly designed to control and / or monitor a smoke extraction fan and / or its redundant fan, whereby the fans can preferably be used for mechanical smoke extraction from buildings and / or parts of buildings, for the ventilation of underground garages, and / or for the general control of other units and their redundancy in the event of a malfunction.

[0026] An additional BUS module can, for example, be provided for integrating a key switch with preferably three LEDs for status display. The status display can, in particular, relate to the assigned systems, whereby a control can be provided to the fire department with priority. This additional BUS module can, in particular, be configured to trigger a smoke extraction system, a smoke extraction system, and / or a selected scenario according to the fire control matrix.

[0027] Additional BUS modules can be configured to integrate push-button detectors, to control and monitor ventilation systems, or to connect to a time signal transmitter. Furthermore, the proposed system can include a communication module that can be used, for example, to transmit events and operating states, such as triggered scenarios, system messages, and / or feedback from limit switches.

[0028] Application tests have shown that, with the present system, BFSM systems for building automation, which are significantly easier to detect, can process incoming events that require action much more quickly and with less error-proneness, and respond appropriately. A particular merit of the invention is that the proposed system can be operated and managed by laypersons and ordinary employees. It is therefore no longer necessary for an IT specialist to monitor and / or maintain the system's operation; instead, the sensor data is preferably transmitted automatically and independently to a processing unit on which the modified BFSM comprising the first, second, third, and fourth matrices is stored and / or operated.

[0029] The proposed use of a modified BFSM makes it possible, in particular, to dispense with the use of source code. To operate the system, preferably only parameterization is required, which, however, can be performed without extensive programming knowledge. This is preferably made possible in particular by the fact that the system's actuators are formed by decentralized, distributed BUS modules that together form a BUS system. Thus, decentralized intelligence can advantageously be used to control the system. Within the meaning of the invention, it is particularly preferred that the modified BFSM, together with other elements, forms a configuration file with which the system and / or the technical installation can be controlled.

[0030] According to the invention, it is preferred that the proposed system be configured to link the technical components of the technical building automation (TGA) system with the mechanical smoke extraction systems and other safety-relevant systems. This link advantageously makes it possible to control the TGA and / or the safety-relevant systems, in particular the smoke extraction system. Preferably, the smoke extraction system and the other safety-relevant systems can be switched on or off. Due to the use of a modified fire control matrix, the proposed system is also preferably referred to as a matrix system.

[0031] According to the invention, it is preferred that the processing device and / or automation station are configured to activate a corresponding control zone when the proposed system, or its sensors, detect a triggering event. The triggering of the event can occur, for example, in connection with the fire alarm system and / or an MRA button, or alternatively, it can be detected by the input matrix of a BUS module. According to the invention, it is preferred that the links to the configuration file are stored in the BUS modules.

[0032] It is further preferred within the meaning of the invention that the measures required within a building in the event of a fire or safety incident be determined and / or defined by a fire protection expert. In particular, the fire protection expert specifies in the fire control matrix which measures the proposed system must initiate and under which conditions. It is preferred within the meaning of the invention that the manner in which this occurs represents the technical solution of the proposed system.

[0033] According to the invention, it is preferred that so-called scenarios are triggered by the fire alarm system (BMA) or other triggering and / or operating units. The corresponding data can be transmitted, for example, using a BMA coupler. Other triggering and / or operating units can be, for example, MRA buttons, toggle switches on the fire service smoke extraction panel, or free contacts of a gas warning system, as prescribed, for example, in the underground car park regulations. In one application example, the triggering of the powder extinguishing system for a grease fire in a commercially operated kitchen can lead to a safe shutdown of the kitchen supply air. An Ansul control system can also be used for this purpose.

[0034] According to the invention, it is preferred that the proposed system comprises a processing unit on which the modified BFSM can be stored. According to the invention, it is preferred that the BFSM or the modified BFSM is stored in the configuration file in part or in its entirety in the BUS modules. This processing unit can preferably be formed by the automation station of the smoke extraction system or of the proposed system. In particular, the proposed system enables both a human user or operator of the technical system and the processing unit to record the events and actions to be initiated particularly quickly and to initiate and process the necessary measures efficiently, in a structured, and optimized manner.This allows, for example, system malfunctions or actual fires to be remedied or combated particularly effectively, thus minimizing any damage to people and property. Advantageously, the use of the proposed system reduces the system's susceptibility to errors and optimizes and accelerates processing and communication processes. These advantages are achieved in particular by the BFSM, which is comprised of four sub-matrices, and its interaction with the sensors and actuators of the technical system.

[0035] For the purposes of the invention, it is preferred that the technical systems are preferably automated systems or systems for technical building automation, safety-relevant controls, fire protection systems, smoke extraction systems, fire damper controls, and control systems for fans, for example, in underground garages.

In particular, the input matrix (10) is configured to link triggering events to the associated zone. This advantageously allows a location within the building, the system, and / or the technical installation to be assigned to the triggering event.The linking matrix (14) is preferably configured to link or connect zones, installations, and / or components of the technical installation and / or system to one another. In particular, the linking matrix can also block and / or disable zones. The signaling matrix (12) is preferably configured to control the proposed system, which is particularly necessary in the event of special events. A special event can, for example, be the failure of an important hardware device. The output matrix is ​​preferably configured to control the actuators of the system and / or technical installation, wherein this control preferably takes place per zone, preferably separately by zone, and for each zone individually.
