vibrating alert

Field of engineering

The present invention is based on an alarm device for triggering a vibration alarm.

The present invention is further based on a

Method for operating an alarm device for a

Plant of basic industry, wherein a

Evaluation device Signals from sensors via a

Data line of a plant of the basic industry receives, wherein the evaluation device evaluates the signals and checks whether they exceed a predefined critical value.

Equipment of the basic industry and the associated

Monitoring methods are known in many embodiments. The installations may, for example, be installations of the paper industry, the chemical industry or the metallurgical industry. Especially at the metallurgical

Industry come as plants such as a blast furnace, a sintering plant, a converter, a ladle furnace, a

Continuous casting, a rolling mill or a filter system in question.

State of the art

Operation and monitoring of facilities of

Basic industry today takes place to a large extent in control stations and control stations. In these control or control booths all information of the plant of the

Basic industry or part of the plant of

Primary industry brought together and visually to the

Operating personnel output. The output is usually via screens, control panels, scoreboards and the like more. In particular, it is possible for several screens to be arranged next to one another at a specific location in order to allow the operating personnel a comprehensive overview. In the control and steering stalls are considered responsible

Staff often only a few people present, sometimes even a single person.

In the prior art, the issuing of alarm messages to the operator is usually done visually via a

Screen. In principle, this procedure

unproblematic. However, it is necessary that the

Operator permanently keeps the screen in view.

If this is not the case, it can happen that in a visual display alarm messages are delayed or even overlooked.

In principle it is possible, in addition to the visual

Output of alarm messages via the screen as well

To provide acoustic signals, such as a

Alarm bell or alarm horn. However, this would be an even further increase in already very high anyway

Lead to noise levels. Furthermore, due to the large number of possible alarms, this would result in a blunting of the

Lead operator.

Alternatively, it is possible for the operator to call someone else by telephone about the presence of a person

Alarm state is informed. In this case, however, an active action by another person is required.

In completely different subject areas - for example at

Mobile phones - it is known, alternatively or in addition to a visual and / or acoustic signal

Vibrating signal to trigger, for example, at a

incoming call. Also with other objects like

for example, computer games are vibration signals

Summary of the invention

The object of the present invention is

To create possibilities by means of which the operating personnel - in a simple and reliable way - can be made aware of critical conditions of a plant of the basic industry and the device is operated energy-efficiently.

The object has been achieved by an alarm device, comprising a first plate, which is for stopping

Objects is suitable and at least one actuator for displacement of the first plate in vibration and at least a first attachment for placing the first plate at a predetermined distance above a floor. The actuator should at least temporarily, during an active state of the

Actuator, contact with the first plate and be adapted to put the first plate in vibration. Furthermore, the alarm device has a first attachment, which is suitable for the first plate in a predetermined

To place a distance above a floor.

The actuator is advantageously so on the first plate

arranged so that the actuator can vibrate the first plate. Preferably, the actuator is at one

Bottom of the first plate arranged and must be so

be executed that it activates vibrations when activated, which are clearly felt by a human. Of the

Actuator preferably has a movable mass. The agitated mass is operated in a frequency range of 2 to 2000 Hz, preferably 2 to 100 Hz, and the weight of the agitated mass is 20 to 2000 grams, preferably 20-500 grams. The weight of the moving mass depends on the material, the size and construction of the first plate. The first attachment is for example at least one table base of a table top, a wall bracket or a ceiling console, which the

Table top at appropriate height above the floor

attached. The height - on which the first plate is to be placed - depends on whether the table top is intended for standing or sitting work.

In the embodiment that the first plate a

Floor element is provided as an attachment a spacer. Such a spacer may for example be designed as a damper. The first plate is preferably a tabletop on which the keyboard, screen, books or similar items can be placed. Another possibility is that the first panel is a floor element on which chairs or similar objects can be placed. By the first plate, the vibrations generated by the actuator can be transmitted well. The actuator directly vibrates the first plate, preferably the actuator is disposed directly on the first plate. This ensures that people can reliably perceive the vibrations, regardless of where there is a direct or indirect contact with the first plate. The first plate is stiff - that is, not soft and not very pliable - designed to allow the plate to transmit vibrations felt by human beings. The first plate is preferably solid and has no voids in the interior of the plate. The first plate allows one

Propagation of vibrations generated by the actuator. The first plate is therefore not an elastic component, which without additional support structure

can not keep the intended shape. The first plate is preferably designed such that an operator has a body part in direct contact with the first plate, for example by a part of the arm or a part of his hand directly touching the first plate or a part of the foot directly touching the first plate.

The embodiment of the invention provides that a vibration damper, between the first plate and the at least first attachment, is arranged. This

Vibration damper ensures that the smallest possible portion of the vibrations is transmitted to the at least first attachment. The transmission of vibrations from the first plate to the first attachment is by the

Minimized vibration damper. Furthermore, it is achieved by the damper that as free as possible oscillation of the first plate is allowed. A damper makes the vibration of the first plate even more noticeable to the operator. By means of a damper, the actuator can also be made smaller, since it does not have to additionally apply the energy that is transferred to the first attachments.

The advantage of the present alarm device results from the fact that the vibration of the first plate arouses special attention in the operator. The vibration is immediately noticeable, even in a noisy environment or when the operator does not keep an eye on the displays.

Since the work of the operator requires a great deal of attention and is correspondingly demanding, it can orkommen repeatedly _V that the operator, for example, gets up from the couch or leaning back. However, the operator recognizes the alarm by the vibration of the first plate. The items on the first plate - like

For example, keyboard, key or mouse - set in motion by the vibration of the first disk. If the first panel is a floor element, then the operator can feel the vibration, whether standing or sitting. In the known in the prior art embodiments that the driver's seat or the steering wheel vibrates, the operator gets these vibrations only when sitting on the seat or touches the steering wheel.

The preferred embodiment of the first plate is a tabletop, which may be part of a desk on which screen, keyboard or similar devices can be placed. Another embodiment of the first panel is that it is a part of the floor - on which stands, for example, a desk chair. The floor element can stand on a finished floor of a building. Another possibility is that the floor has a recess into which the plate can be inserted.

A preferred embodiment provides that the actuator is arranged such that it can set the first plate directly in vibration, preferably, the actuator is attached directly to the first plate. The actuator puts the first plate directly into vibration, preferably the

Actuator arranged directly on the first plate. This ensures that the energy of the actuator used as fully as possible to put the first plate in vibration. An advantageous embodiment provides that the first attachment is a table base, a spacer, a wall bracket or a ceiling console.

The table base and wall bracket are particularly well placed to place the first panel so that the operator can either sit or stand. It is also conceivable that the first plate is placed over a ceiling console. The overhead console is attached to a ceiling of a room, placing the first panel at a desired distance above the floor. The spacer serves primarily to allow the embodiment in which the first plate is a floor element to be placed at a certain distance from the floor. If the plate were lying flat, the generation of the vibration would be very energy intensive. Such a spacer may for example be a damper, which preferably has corresponding attachments to palpate the damper on the floor. This damper allows a

as free as possible vibration of the first plate.

A further preferred embodiment provides that the actuator is connected to an evaluation device which is suitable for processing and evaluating signals of an industrial plant and to activate the actuator at critical signal values. The evaluation device receives signals from the industrial plant and can evaluate them accordingly. At critical values, this evaluation device activates the actuator, causing the first plate to vibrate.

A particularly preferred embodiment variant is that the alarm device has a second plate. This second plate, which is suitable for storing objects, is connected to at least one second attachment, wherein the second attachment is adapted to place the second plate above the floor. This second plate is decoupled from the first plate. This design is particularly suitable for the fact that the first plate only covers the part on which the operator of the industrial plant is supported, for example, the part where the keyboard is located. In the execution of the first plate as a floor element, it makes sense only to put that part in vibration on which the operator stands or on which a chair is placed. The second plate is then that part on which, for example, the screen is standing - in the execution of a vibrating table top. In the version with a vibrating

Bottom plate, the second plate, for example, a

Be tabletop, on which the screen is. The second attachment is then, for example, the table base is attached to the table top. The second plate should not be vibrated. Under decoupled in this context is understood that the first plate and the second plate are not directly - without a damping element - are connected. The two plates are advantageously mounted at the same height, but have a distance from each other. For safety reasons, this distance can be protected by a cover or a damping element to avoid the risk of injury. This embodiment has the advantage that only that part is vibrated, in which the operator resides. Thus, several operators may also be arranged a plurality of first plates in order to selectively alert only selected operators can.

Another embodiment provides that between the first plate and the second plate a protective device is mounted. This protective device must be capable of preventing introduction of body parts into a gap between the first plate and the second plate. Another feature is that no foreign objects can enter the gap and get stuck in it, which will affect the function of the alarm device. This protection device may be a cover to protect the gap between the first plate and the second plate. This is advantageous because otherwise there is a risk of injury when, for example, the fingers, feet or other body parts are in the gap and the Actuator is activated. The protective device may also be a damper element which is mounted in the gap.

A further advantageous embodiment provides that the actuator is an eccentric flywheel and / or a

electromagnetic flywheel and / or a

Has body sound transducer. These actuators are particularly well suited for transmitting vibrations to the first plate.

An advantageous embodiment of the alarm device is that the vibration damper has a stiffness between 10 N / mm and 2000 N / mm.

An advantageous embodiment provides that the first plate has at least two actuators. This has the advantage that the alarm is noticeable over a larger area.

A particularly advantageous embodiment provides that an oscillating mass of the actuator moves between two end positions and the oscillating mass touches the first plate, at least in one of the two end positions.

This embodiment of the actuator, has the particular advantage that it is particularly well vibrated by contact of the oscillating mass with the first plate. Furthermore, by touching the first plate with the oscillating mass, a good perceptible noise is additionally generated.

The task is further enhanced by the use of

Alarm device in a plant of the basic industry, in particular a blast furnace, a sintering plant, a converter, a ladle furnace, a Strangießanlage, a rolling mill or a filter system, solved. In such a system, the alarm device is particularly well suited to transmit critical conditions to an operator of such a system. The object is achieved with the aforementioned method in that when exceeding a predefined

critical value the alarm device according to one of

Claims 1 to 11 is activated.

The human sense of movement is very pronounced and active at all times. The operator is by a

Alarm device for triggering a vibrating alert, so even then made aware of a particular alarm condition when it is otherwise distracted, for example, because it speaks to another person - by phone or directly -. Also, such a vibration also by

Clothing, protective gloves, safety shoes and the like can be felt through. The inventive method for operating an alarm device further causes the operator is alarmed particularly reliable.

An advantageous embodiment is that the plant of the

Basic industry a blast furnace, a sintering plant, a converter, a ladle furnace, a continuous casting, a

Rolling mill or a filter system is.

In such systems, there are a particularly large number of sensors monitoring the systems and it is often possible for critical states to occur, which is why it is particularly important to ensure reliable alarming in order to avoid danger to people, equipment and the environment.
