Description

  • The invention relates to a method for monitoring buildings.
  • As part of a building surveillance, the buildings and their existing facilities and valuables can be checked for unauthorized access or proper functioning. It is common to monitor using special sensors, such. As vibration sensors or motion sensors on the objects to be monitored. The sensors are connected either by means of a single wiring or via a network connection to a central evaluation unit which can recognize the messages from the sensors and assign them to corresponding events. The disadvantage of this is the rather high cost, which is associated with the sensor assembly and the connection of the sensors to the evaluation. There is therefore a need to significantly simplify the setup of monitoring systems. It should be dispensed with intelligent sensors and the wiring costs are kept as low as possible.
  • The object underlying the invention is achieved by a method for monitoring the building according to claim 1 and a monitoring arrangement according to claim 5.
  • The core of the invention is that the device-specific single-power consumption curve or device-specific pattern in the single-power consumption curve of individual connected devices is used for building monitoring. Namely, each device has a device-specific power consumption, which can be recognized in a significant pattern of the total power consumption curve. For example, inductive consumers have an initially very low power consumption, which increases continuously with the structure of the magnetic field within the inductive consumption. Characteristics, such as time constants, amplitudes or frequencies of constantly recurring events, can also be used to detect individual consumers. For a room monitoring to detect an unauthorized entry, for example, a headlamp with integrated or connected motion sensor can be used. The motion sensor would detect a person entering the room and turn on the headlight. Instead of now consuming to transmit the sensor signal by network or single wiring to a processing arrangement, the headlight is simply turned on first. Turning on the headlamp can then be demonstrated in the total power consumption curve based on the device-specific power consumption. The advantage now lies in the utilization of the existing power line as a data path while avoiding expensive network-capable sensors.
  • The invention makes use of the already known functioning of the smart meter, ie the intelligent electricity meter, as its own. Such smart meters will already be used to detect individual consumers, as in the not yet published German patent application 10 2010 046 417.1 described. The invention is now also in the novel use for monitoring purposes, in particular as an alarm system for monitoring rooms or other places against unauthorized entry. In such use, the message may also be output in the form of an alarm.
  • Now it is possible that the device-individual single-power consumption curves are not suitable for an exact assignment of events to concrete consumer devices. This may be the case when multiple identical devices are used, for example, multiple headlights of the same type. Then, it could be determined from the total power consumption curve that any one headlamp of this type is turned on; but whether it is the headlamp in the basement, the headlamp in the garden or the headlamp in the attic can not be determined. In a preferred development, consumer devices, of which in particular a plurality of identically constructed devices are used in the building, each assigned to a modulator, which modulates the individual power consumption curve a device-specific pattern. Thus, therefore, the single-power consumption curve of the consumption device is manipulated defined. This imprinted device-specific pattern is then recognized by the evaluation arrangement. The advantage now lies in the fact that a differentiation between identically constructed consumer devices is now possible within the scope of the evaluation. Such a manipulation can be generated, for example, by a simple active electronic component, such as a triac or thyristor, which, when the consumable device starts to operate, applies a defined current pulse to the unmanipulated single-current consumption curve. In this case, if the modulator is connected in series, the individual consumption can actually be influenced at least for a short time. This could manifest itself in an unacceptable tiny flicker of the headlight. Such defined manipulations are then taught the evaluation arrangement in advance.
  • The invention will be explained in more detail below with reference to the figures. Hereby shows:
  • 1 a daily load curve on the electrical consumption of a 1-person household and Individual consumption curves of individual appliances in this household;
  • 2
    • a) an unmanipulated sinusoidal single consumption curve of a headlamp,
    • b) an inventively manipulated by a modulator single consumption curve of the headlamp;
  • 3 Characteristics of an inductive load;
  • 4 a flow diagram of the method according to the invention.
  • In 1 is an ordinary daily load curve over the electrical consumption of a one-person household. The current consumption curves I of individual consumers are shown over the time t. A curve E represents the cumulative daily energy consumption of the household at the time. I 1 symbolizes the power consumption curve of the most powerful consumer, namely a water heater for generating the warm water for the morning shower. Alone due to the sheer amount of the Leistungsaufufs at a certain time, the function of the water heater can already be detected. The small power peaks of the curve I 2 that are recurring in continuous intervals are caused by the regular switching on of a refrigerator. In the evening, the stove causes a significant power consumption I 3 . Subsequently, the washing machine is turned on, which causes a power consumption I 4 . The drying of the laundry can be recognized by the power consumption I 5 . In the evening, the TV is still operated and the apartment illuminated, which can be seen in total on the basis of the curve I 6 .
  • On the basis of the power consumption curve I 2 is a regularity of switching on the refrigerator can be seen. At a distance of about 90 minutes, the cooling of the refrigerator usually turns on. The regularity with which the power peaks appear in the total power consumption curve already represents a pattern after a device, namely the refrigerator in the present case, can be detected. If the characteristic current peaks, which indicate the switching on of the refrigerator, do not occur regularly as expected, then it can be assumed that the refrigerator is defective. If, for example, the resident of the house is on a longer journey, he could, if he has knowledge of the malfunction of the refrigerator, ask his neighbor to check the refrigerator.
  • Such "macroscopic" patterns, such as the very high power requirements of the flow heater and the regularity of the refrigerator, are still relatively easy to determine from the overall consumption curve. The situation is more difficult if several devices of the same type are used and, in concrete terms, the function of a single device is to be recognized from this quantity. For example, a plurality of headlamps are provided in the building, all of which are controlled by a respective motion sensor. In this case, for example, safety-relevant rooms or entrance areas can be monitored. If there is a person in a security-relevant room at a time when a person has no business there, a break-in is to be expected. Due to the detected movement of the burglar, the lamp is turned on, which in turn makes its contribution to the overall power consumption curve. Now, however, an individual lamp can not be distinguished from a similar other lamp due to their current characteristic, which is attached, for example, to another non-critical point of the building. Therefore, the current characteristic of this lamp is selectively changed according to the invention, as described 2 is explained.
  • First shows 2a simplifies the sinusoidal current flow 13 through a light bulb. Identical power consumption curves also have other identical lamps. However, in order to recognize that the current curve is exactly one concrete individual lamp, this lamp is preceded by a modulator which specifically influences the current curve for this lamp. Thus, for example, a spike 12 be introduced as a pattern in the sinusoid, as in 2 B is shown. This spike can occur once when the lamp is switched on or every time the sine wave passes through at the same place. An evaluation unit is now trained accordingly and detects exactly this point to the specific phase of the sine wave. Every time this wave appears in the sine wave, the evaluation unit can determine that exactly this individual lamp is lit, which indicates a motion triggering the corresponding motion sensor in the vicinity of this lamp. If the evaluation unit is programmed in such a way that a break-in is probable at a certain time on this motion sensor, then a message to the user (including a security service) can be sent, for example, by SMS or e-mail.
  • In 3 are the supply voltage ( 3c ), the current curve ( 3b ) as well as the self-induction voltage ( 3a ) when operating an inductive load. The Current curve I represents the single current consumption curve 13 Due to the characteristic shape of the power consumption curve 13 during the applied supply voltage U C and during discharging when the supply voltage U C is turned off , the curve 13 in their entirety as a device-specific pattern 12 be considered.
  • In 4 schematically an arrangement is shown, based on the method of the invention can be performed. An electrical consumption 1 in the form of a headlamp, which is equipped with a motion detector, in the lighting mode has a power consumption by the single-power consumption curve 13 is shown. A modulator 5 who works together with the headlight 1 a consumable unit 6 Represents the single-power consumption curve 13 with a characteristic spike 12 that represents a pattern. The so manipulated single power consumption curve 13 ' will, along with other consumption curves 17 to a total power consumption curve 11 summed up, then the pattern 12 at the appropriate place in the sine wave. The total power consumption curve 11 is then through an intelligent power meter 7 added. The electricity meter 7 now can the total power consumption curve 11 digitally process. The digitally processed total power consumption curve 11 ' becomes a demodulator 8th made available. The demodulator 8th can be characteristic patterns from the digitally available total consumption curve 13 ' with within the demodulator 8th compare deposited patterns. So he can also do the pattern 12 detect. A subsequently arranged evaluation 9 Now check if the pattern 12 a device is assigned. In the present case, the evaluation unit recognizes the pattern 12 that the headlight 1 shines. Because the headlight 1 is controlled by a motion sensor, a movement in the environment of this sensor can be assumed.
  • The transmitting unit 10 Now sends a message in the form of an e-mail or SMS or in any other form over a telephone line or the Internet to the user 3 here symbolized by a mobile phone. The message can now contain the information that the headlight 1 currently lit or that a person is in the room in which this headlight is located. The news can of course be much more complex and include far more interpretations.
  • Instead of the tooth, the manipulation of the single consumption curve can be made, for example, by a change in the amplitude. A lamp with a common power consumption of 1 A is changed by connecting a resistor as a manipulator so that the unit of lamp and resistor consumes only 0.96 A. The deviation in the amplitude can then be recognized by the evaluation unit as a device-specific pattern.
  • Due to the invention, the behavior detection of the electrical consumers is now exploited on the basis of the individual consumption curves for control and monitoring purposes. Certain switching operations now require no sensors. Instead of sensors, the modulators and the demodulators can now step. All information can be transmitted via the building's normal power lines. Changes in the total power consumption curve can thus be assigned to individual devices. From this conclusions can be drawn, which event happened at which time and at which place. All findings can be communicated to a user via the Internet or via mobile phone.
