Monitoring device

The invention relates to a device for monitoring and triggering a fault message for an area to be secured, consisting of several functional units, comprising at least one sensor that detects a monitoring area and records an event taking place in the monitoring area, and at least one actuator that indicates the event, wherein a multi-core information line is provided for transmitting information, of which a pair of wires belongs to a data bus to which the sensor and the actuator are connected, and information from the sensor is received by the actuator via the data bus and used to trigger a recorded message from a voice memory.

A circuit arrangement for a fault detector is known from DE-GM 88 08 212....In this arrangement, the fault detector's reporting line also serves as a mains voltage line for a fault signaling contact. The fault signaling contact is looped into the mains voltage supply line.

2nd wire pair

A voice output device is provided for the well-known fault detector, which can be used to call up a voice previously stored in a digital voice memory in the event of a fault. This means that in addition to the usual acoustic and optical detectors, a higher level of information about the fault can be communicated in the event of a fault. Furthermore, in combination with a passive infrared motion detector, a burglar alarm can be implemented, which emits a dog barking as a deterrent. The voice memory can also be loaded with any acoustic symbol. The voice output is via a loudspeaker.

The object of the invention is to create a monitoring device with pre-programmed functional units and a voice output device that is operated in a simple manner via a multi-core information line with free wires. In particular, a possibility for using the free wires for voice transmission should be created.

The object of the invention is achieved by the measures listed in the main claim. Further developments of the invention are described in the subclaims.

2nd wire pair

In the embodiment according to the invention, an actuator is used which contains a voice memory with recorded acoustic messages. The voice memory can be connected to a multi-wire information line, one wire pair of which belongs to a data bus and of which at least one other free wire pair is available. This free wire pair is available for voice transmission.

The voice memory can be connected to the data bus and has, for example, an NF output for connection to the free wire pair that is used as a voice transmission line. The acoustic messages can be called up via the data bus and are output via a loudspeaker that can be connected to the voice transmission line. The EIB bus (European Installation Bus) can be used as the data bus.

The invention provides a very high level of flexibility when installing the monitoring device, so that "security within your own four walls" can be improved in a simple way. ... ...... . ......

The monitoring device warns the sleeping resident of a burglar and, depending on the version _, can also wake up the neighbors or inform the security service. Parents or neighbors can be alerted if smoke is detected.

occurs or a fire breaks out. A message is sent when the heating system goes into "fault" mode. An acoustic signal can be given: "The freezer is defrosting" or "Heating oil needs to be refilled".

Because the monitoring device consists of functional units (modules), it can be installed completely in a housing or control cabinet, or individual modules can be placed separately at any location as required and desired. Individual modules, for example an additional voice memory and a loudspeaker, can also be installed in another apartment or in neighboring houses.

By designing the functional units (modules) as bus-capable, it is also possible for several monitoring devices to communicate with each other and pass on alarm and fault messages. Where laying the information line is not possible or not practical, the connection can of course also be made via radio or infrared. ~* - - , .·■-■ · . '

The individual functional units (sensors, actuators) are pre-programmed. The entry-level version of the monitoring device can initially consist of a power supply, a switching actuator and a motion detector as well as a voice memory.

2nd wire pair

By adding further functional units such as additional motion detectors, window and door detectors, smoke detectors/level switches, standstill detectors, the monitoring system can be expanded at any time without any programming effort. The monitoring system can be expanded into a complete alarm system by installing a display unit and an arming device.

The functional units are preferably certified devices from the building automation system, so that the monitoring device can also be integrated into the building automation system. Such a system for the building automation system includes corresponding devices for switching, controlling, regulating, measuring and monitoring. These functional units are connected to one another via the information network (data bus) and each has a bus coupler at the end points for connecting a sensor or actuator. This creates a decentralized system with which signal telegrams can be exchanged in both directions and received commands can be evaluated and processed. ■■--. - ·..,.. .

The voice output device comprises a voice memory and at least one loudspeaker. A voice memory in the sense of the invention is generally understood to be a memory that stores acoustic signals of any kind. The voice memory is preferably

partly designed as a series-mounted device with a housing and can be snapped onto a profile rail. The voice memory has a bus coupler and can communicate with the sensors connected to the data bus, so that the messages previously recorded in the voice memory can be called up. Loudspeakers can be installed decentrally in the building but also in adjacent buildings or other apartments in flush-mounted boxes. Common bus systems for building management technology... have a four-wire cable, two of which are used for telegram transmission. The second pair of wires is not required for the bus. The wiring to the loudspeakers is done via the second pair of wires of the cable. The free pair of wires can therefore be used for voice transmission in a simple way by connecting the voice memory to the pair of wires of the bus cable and connecting it to the free pair of wires. The output of the voice memory for voice transmission can be designed as an analog output (AF output) or as a digital output, and accordingly the loudspeaker can be a passive loudspeaker or an active loudspeaker that is able to convert digital sound signals and reproduce them acoustically.

The operation of the monitoring device can be decentralized as already described, whereby

addressing the bus coupler means that data traffic takes place directly between the individual functional units". It is advantageous to use a display unit through which all data traffic runs. This display unit is installed near the door and has optical means with which the status of the sensor channels can be seen at a glance. A green display can mean that a detector has not responded or that a window is closed. A red display can mean that the detector has responded or the window is open. A flashing display can mean that the line to a detector is interrupted. The monitoring device can include an arming device, which in the simplest case is a key switch with which the display unit is switched on or off. By installing a bus coupler, the key switch can be connected to the data bus.

An embodiment of the invention is described in more detail below with reference to the drawings.

Figure 1 of the drawing shows a schematic representation of a monitoring device for an area to be secured 1. The area to be secured is shown here by a dashed square. This square can, for example, include a piece of land with a building on it. >..;

The property and building are equipped with sensors, each of which covers a specific monitoring area of the area to be secured 1. For example, a motion detector 2 is shown here as a sensor. Several units of this motion detector, which can be a passive infrared motion detector, can be installed inside and outside the building to secure it, so that movements of living beings that enter the monitoring area are detected. A window sensor 3 is also shown here as an example, which reports whether a window is open or closed. Door sensors can also be installed on the doors. Window and door sensors can of course be installed on all windows and doors in the building. Finally, a sensor device 4 for technical alarm messages is shown here as an example

2nd wire pair

which detects whether the heating is on or off, or how much heating oil is still in the tank system 5.

At least one actuator with a switching function is provided, with which the event recorded by the sensors is displayed. This actuator can be a display unit 6, with which the entire monitoring device 18 is switched on and off via an arming device. This is used to trigger a fault message, which is done by operating a horn, a flashing light or by activating a voice output device, with which at least one loudspeaker 7 in the building is switched on and outputs a message recorded in the voice output device. Several messages are stored in the voice output device. These messages can, for example, be as follows:

• "The heating is off"

• "Smoke in the children's room"

• "Only 1000 1 left in the heating oil tank"

• "The cellar door is open"

• "You are a burglar; leave the house"

• "Deadly gas in the garage"

The messages are recorded in a voice memory 8 and are transferred to the signal recorded by the sensors.

ne event or its operating state. The voice memory 8 can be contained in the display unit 6 or be designed as a separate actuator such as a series-mounted device 9 that can be snapped onto a top-hat rail. The voice memory 8 is able to manage several messages as already mentioned. An input key 11 and an indicator light 12 are provided for each message. To record a message, the corresponding key 11 is pressed and the message is entered using a microphone 13 built into the device. Recording ends when the key is released. A message can be displayed using the indicator lights.

A four-wire information line 14 is provided for the transmission of information. A wire pair 15, 16 of the information line 14 belongs to a data bus (bus line 15, 16) via which sensor and actuator information is transmitted in the form of telegrams. For this purpose, the devices of the monitoring system are designed as modular functional units for the building management system and each contain a bus coupler 17 with a microprocessor that can be connected to the bus line 15, 16. With the bus couplers 17, telegram traffic can be conducted between the functional units in both directions, i.e. this is a decentralized system that

does not require a control center. The voice memory 8 can therefore be controlled directly by the sensors or indirectly via the display unit 6 if the voice memory 8 is designed as a separate functional unit. The display unit 6 visually displays information about the operating status of the voice memory 8. A green display can mean that the voice memory 8 is not activated. A red display can mean that the voice memory 8 is activated. This means that even if a loudspeaker is installed far away from the display unit 6, it can be determined whether a message is being or has been issued. Of course, as already mentioned at the beginning, all operating statuses of the sensors and actuators can be visually displayed with the display unit. Furthermore, the display unit 6 can be activated or deactivated by the arming device 18 via the data bus. In the simplest case, the arming device 18 is a key switch with an illuminated display.

The voice memory 8 contains a digital memory module 19 with dynamically usable memory locations, so that the saved memory space for short messages is available for longer messages.

2nd wire pair

The voice memory 8 contains a digital-analog converter 20, which is connected to an AF amplifier 21. The output of the AF amplifier is connected to the second wire pair of the information line, which is used as a voice transmission line 22, 23. Both wire pairs are contained in a common line.

The voice memory 8 and at least one loudspeaker 7 can be connected to the voice transmission line 22, 23 to emit an acoustic message. The voice memory 8 transmits the recorded messages in the form of NF signals with the voice transmission line 22, 23 depending on the sensor information received and outputs them via the connected loudspeaker 7. Several loudspeakers 7 connected in parallel can be distributed decentrally in the building but also in a neighboring apartment or building and installed in flush-mounted boxes so that with a corresponding loudspeaker output power and adapted impedance, for example, a loudspeaker with 2 watts or 20 loudspeakers with 100 mW each can be connected. In this variant, a message is output via all loudspeakers 7.

Another variant provides that each loudspeaker 7 has a bus line 15, 16 that can be connected

2nd wire pair

This means that a message can be output specifically to a correspondingly addressed loudspeaker 7.

As Figure 1 shows, in addition to the security area 1 shown as a dashed square, there is also another area 24, which is symbolized by a dashed house. This area 24 is located outside the area 1 to be secured and can be a building adjacent to the security area 1 or another apartment. As Figure 1 shows, the four-wire information line 14 leads out of the area 1 to be secured and into the other area 24. In this area 24 there is another voice memory 25, which can correspond to the first voice memory 8, i.e. is identical in construction to the first voice memory 8. This voice memory 25 also contains recorded messages and is connected to the data bus (bus line 15, 16) and receives sensor information from the area to be secured. At least one loudspeaker 7 is connected to the voice transmission line 22, 23 in this area, which can output the messages contained in this voice memory 25. In order to avoid mutual influence of the voice memories 8, 25, i.e. interference with the voice output, the voice memories 8, 25 can be activated optionally, for example, the voice memory 25

2nd wire pair

not activated if the voice memory 8 is activated. Voice output via both voice memories 8, 25 is easily possible if the voice transmission line 22, 23 is interrupted in the transition area (shown in dashed lines in Figure 1).

The voice memory 25 can contain, for example, the following messages:

•"There are burglars in the Meiers' house"

• "There is a water leak in the IT department"

• "Help, please call the police"

With this arrangement, an event recorded by the sensors in the security area is received by the second voice memory 25 and output as a message via the voice transmission line 22, 23 with the loudspeaker. Of course, several loudspeakers 7 can also be distributed here. Because a voice memory 8 reporting the event or displaying the operating status of the sensors is provided in the security area to output a message and another voice memory 25 is provided in the neighborhood area, with which a fault message is transmitted from the security area 1 to the outside, a network is created through which the neighborhood can be alerted.

2nd wire pair

The neighborhood voice memory can be activated separately.
