DE102008058127A1 - Fire alarm system for providing protection to machine tool, has control devices staying in connection with sensors, receiving fire alarm signal using sensors and associated to objects, where sensors are respond to fire - Google Patents

Abstract

The system has sensors (3) associated to objects (1) to be monitored, where the sensors respond to fire. Control devices (2) i.e. microprocessors, are in connection with the sensors and receive a fire alarm signal using the sensors. The control devices are associated to the objects. The control devices are connected to a common control center (4) i.e. personal computer, over a loop wiring system (5). The control devices are programmed independent of each other with respect to a setting parameter. An LED is provided to indicate status of the system.

Description

The The invention relates to a fire alarm system in the object protection in the frame a plurality of to be monitored with regard to a fire outbreak Objects according to the preamble of claim 1.

Basis of the invention is the so-called object protection, as in DIN 0833 is described. The object protection is characterized by the fact that very specific objects are monitored, whether they trigger a fire or in them a fire is triggered. The objects may, for example, be machines. This means that in this object protection, the monitoring device is assigned specifically to a specific object (and only to this object).

Around to detect a fire in the above-mentioned property protection, There are many different types of sensors. These can be on Temperature, UV, IR, difference measurements, etc. are based. Everybody is here at least one sensor associated with the objects to be monitored. The sensors are connected to one for all Sensors common, central control device connected. Of this central control device go star-shaped, the test leads to the individual sensors of the objects.

The Problem with this system of a fire alarm system is that that the system is very inflexible. A particular disadvantage is that a central control device provided is, from where by an appropriate laying of the cables Sensors are controlled on the individual objects. For example an object has to be placed with regard to its site, the Direction from the central Steuerein direction to the associated Sensor removed and a new line to be laid. This is always associated with a considerable effort.

From that Based on the object of the invention, a fire alarm system in the object protection in the context of a plurality of regarding a Fire outbreak to create surveillance objects, which can be handled very individually.

The technical solution is characterized by the features in the characterizing part of claim 1.

Thereby is a decentralized security management created, which is very can be used individually. In the controller acts it is a single-zone extinguishing center. This can be as Fire alarm control panel as well as fire alarm control panel with electrical Control device for controlling external warning devices and extinguishing systems be used. The basic idea is thus in a control device, which fully responsible for the assigned object is and above all works independently. It is to the used monitoring sensors connected and can hence the corresponding signals from these monitoring sensors to process. For example, the control device is connected to smoke / heat detectors, Optical smoke detectors (eg scattered light smoke detectors), manual call points etc. connected. When such a control device triggers, Of course, something has to happen. So can For example, a siren can be controlled, it can be the fire department be alerted, an extinguishing system can be controlled etc. For this purpose, the control device has corresponding outputs. At the same time the supervised outputs become constant checked for short circuit and wire break. locations the fire detection system according to the invention are, for example Control cabinets, spark eroding machines, machine tools, Computer system, soldering machines, fume hoods and much more more.

each individual control device is indeed independent and independent of other facilities, but proposes the development according to the claim 2 before that the individual control devices to a common Control center are connected. This control center is acting It is a PC, which monitors all individual control devices. There, the relevant data is also entered centrally. So can on This way it can be very easily determined what disorder at which place.

there can claim according to the development 3 the control devices via a loop with the Control Center be connected. This means that all Control devices and the control center a communication loop define. This has the advantage that when a position change an object in a simple way the cables changed accordingly can be.

The Training according to claim 4 proposes before that the control device individually and independently programmable from each other in terms of their setting parameters are. This means that it is at the control device are microprocessors with a control panel and a display, so that made there the appropriate settings can be and the states are displayed can be. So LED's can be provided which show the overall status, d. H. Operation, fault, Alarm, forwarding, shutdown, revision, fault of the Alarm device and monitoring device, ground fault, networkerror Etc.

One Embodiment of an inventive Fire alarm system in the property protection is described below with reference to the drawing described. This drawing shows in a purely schematic way a such plant.

They are a plurality of objects 1 provided, which may be, for example, to machine tools.

Each of these objects 1 is with a control device 2 fitted. This is directly part of the object to be monitored. This control device 2 is associated with at least one sensor 3 ,

Finally, a control center is provided in the form of a PC. The control devices 2 as well as the control center 4 stand over a loop 5 in contact with each other.

The operation is as follows:
Each of the control devices 2 is independent of the other control devices 2 the fire alarm system trained. To the controller 2 is the assigned sensor 3 connected. Once the controller 2 over her sensor 3 receives a fire alarm signal, a signal is triggered. For example, a siren is controlled. Through the ring line 5 will also be in the control center 4 displayed, which control device 2 has addressed.
