Definitions
- the present invention relates to a system for recording energy and / or material flows in a supply network with end-use or feed-in points, comprising a central data processing device and components for decentralized consumption or feed-in detection in the supply network with detection means for detecting energy - And / or material flows and associated communication means for bidirectional communication with the central data processing device, which is designed to receive and process the measurement data of the components. It also relates to a corresponding component for such a system.
- BUS systems for central building management are known from the prior art, in which consumption measurements do not yet play an important role and their devices, in accordance with their primary controlling function, for a comprehensive, massively decentralized application are not sufficiently miniaturized and are too expensive.
- a separate network is usually installed for the necessary data transfer, so that usually only new buildings can be used.
- a system is also known from EP 0 981 053 A1, in which the current total current consumption measured by one or more permanently measuring and transmitting components is displayed for a household in order to avoid overload conditions, in order to give the user the option of manual or automatic Switch off individual electrical consumers of his choice to reduce the current consumption to a predeterminable value.
- Both of the systems just mentioned serve only to record the total consumption of the individual material or energy flows, so that, as in the prior art, they also only determine the total demand for electrical power or other energy or material flows, which is usually measured only at a few points - often only at a central point as the total consumption of a production unit, an office building or a residential unit.
- the invention enables the "massively decentralized" consumption measurement at any point in the supply network, right down to the individual device, such as a PC, ceiling lighting, etc. It also enables the time curve to be recorded in the spatially distributed demand for power.
- the essential data i.e. the location of the measurement and the measurement data itself can easily be automatically sent to a central data processing device, e.g. B. a central computer for further processing.
- a central data processing device e.g. B. a central computer for further processing.
- the central further processing enables a differentiated and comparative graphical representation of consumption of the individual end consumption points. For example, this can be done in real time on a company's intranet.
- the resulting transparency enables, with relatively little effort, the immediate recognition and assessment of savings potentials of a technological, process and usage-related nature in all contexts of the final consumption of energy or material flows, in particular electrical energy.
- the consumption at the end consumption points can be determined in different ways with the system according to the invention. It can be provided that a component is provided in a first area of the consumption unit at each first end consumption point.
- the first area can include the entire consumption unit, so that in other words a component is provided at each first end consumption point of the consumption unit.
- a component is provided in a second area of the consumption unit at at least one transition point to an end consumer group downstream of the transition point from second end consumers.
- conclusions can also be drawn from the consumption profile at the transition point on the consumption profiles at the subsequent end consumption points.
- Every second end user of the end user group preferably has a specific consumption behavior, by means of which it can be identified.
- the central data processing device is then designed to determine the consumption behavior of the second end user from the recorded consumption behavior of the end user group.
- the components can be attached to sensibly selected branching points or transition points of the supply network.
- Each component arranged in this way measures the sum of all downstream material or energy consumers, the detailed consumption behavior of each individual second end user being deduced from the time-resolved and automated recording of the measurement data of all components distributed in the system.
- This arrangement can be particularly useful if all of the second end consumers downstream of the component frequently show no consumption and the individual consumption values or change profiles, such as, for example, in the case of conventional dimmers or the like, are so characteristic that the individual second end consumer identifies them leaves.
- the automated data evaluation can then use appropriate software to draw conclusions from the time profile of the actual measurement of the consumption profile of each individual second end user downstream of the transition point.
- this arrangement is particularly suitable for recording the consumption of lighting systems and other simple or rarely used consumers in detail at minimal costs.
- the amount of installed hardware is correspondingly low compared to the separate recording of the performance demand of every second end user.
- the detailed information on the individual second end user is not lost due to the appropriately chosen temporal measurement data resolution and the central, computer-aided data evaluation.
- a part of the hardware requirement is, so to speak, replaced by software.
- the decentralized consumption values can be recorded centrally and in principle with any time resolution. Rather, the detailed monitoring of the measured values can also be used to infer defects in individual second end users or other necessary actions, the determination of which without such a system means a considerably higher effort.
- the second area can also encompass the entire consumption unit if the consumption unit is designed accordingly. Furthermore, however, it goes without saying that the two aforementioned variants with components at the end consumption points or at the transition points can also be combined with one another, that is to say the consumption unit can include at least a first and a second region.
- the component is preferably designed to record the energy and / or material flows at short time intervals, for example every minute or every second.
- the respective component comprises a memory connected to the detection means.
- the acquisition means are designed for the continuous acquisition of energy and / or material flows and storage of the acquired values in the form of data series with a fixed temporal resolution in the memory.
- This variant enables a system that is further optimized from a cost point of view without losing important information or transparency.
- the components do not have to be sent continuously to the central processing unit. B. hourly, the collected data series are transmitted.
- the component comprises means for preprocessing the data series stored in the memory.
- This preprocessing can be used for any purpose, for example data smoothing or data volume reduction.
- the means for preprocessing and intermediate storage preferably include a microprocessor.
- the integration of a separate time measurement in the component is not necessary. Instead, due to the number of transmitted measuring points, the time points of the previous reading and, if applicable, a code for the averaging interval used, the temporal reference of the individual measuring points can be concluded.
- the communication means of the component comprise transmission / reception means for transmitting and / or receiving the measurement data series stored in the memory and further information.
- This additional information can be any information.
- this is preferably information which is related to the downstream consumer (s) and their consumption properties or in connection with the component itself and which is used in the subsequent evaluation or display.
- An individual address coding which identifies the component and additionally or alternatively the downstream consumer and additionally or alternatively its assignment is preferably stored in a memory of the component.
- the assignment can relate, for example, to the type of energy or material flow detected.
- the address coding can be transmitted together with the measurement data and, thanks to their assignment, considerably facilitates the processing of the measurement data in the central data processing device.
- the system communication of the system according to the invention is advantageously designed in such a way that it is aimed at the efficient collection of the data series and, moreover, no transmission capacity has to be kept ready.
- the data can be collected according to a predetermined pattern, which ensures that only one transmitter, for example a component, transmits to an assigned receiver at any time, so that there are no mutual blockages.
- the intermediate device also only sends data to the more central unit assigned to it - generally the central data processing device - when this more central unit has requested the data from this intermediate device.
- This enables efficient collection of the data, controlled by the central data processing device, in a particularly simple manner.
- this completely centrally controlled system communication (“pull")
- the partially or completely decentrally initiated communication can also be advantageous. In this case, each component or each intermediate station tries to deliver added data series to the respectively assigned more central unit on the basis of defined procedures.
- the transmission of the data from the components to the central data processing device can take place via any transmission paths.
- the measurement data of the components can be transmitted using a network installed for this purpose. This can be a corresponding conventional data transmission network. It can be used with great advantages in terms of the low installation and investment costs, especially when measuring power consumption, but also the supply network itself - in whole or in part - for transmission.
- the measurement data of the components are transmitted at least on a portion of the route to the central data processing device using a radio link. This preferably takes place starting from the component, which is why the communication means of the component are preferably designed to send and / or receive information, in particular measurement data, via a radio link. Systems with low installation or Set up capital expenditure since there is no hardware-installed network for data transmission in the area of the component.
- the intermediate station makes it possible to summarize the data from larger groups of components.
- the intermediate stations preferably also enable the switch to other data networks (e.g. installed digital networks, radio, etc.), with which faster data transfer may then be possible.
- the groups of components, the data of which are summarized in an intermediate station, can result from their spatial proximity, but possibly also from the phase equality of the supply cables or from other references.
- both the disturbance of the local data transfer on the supply network and the possible disturbance of the surrounding network can be kept low. Disruptions can also be minimized by the fact that, as mentioned above, data traffic on the networks only takes place if possible when the more central unit requests this data, i. H. the central data processing device requests this data from the intermediate station or the intermediate station requests this data from the component. As a result, the data traffic considered here can be restricted to "quiet" times at night.
- the component preferably has a microelectronic structure, since the miniaturization can hereby be achieved particularly consistently.
- the present invention further relates to a component for a system according to the invention, the features and advantages of which have already been explained in detail above in connection with the system.
- the "massively decentralized" consumption measurement of the invention can easily be extended to the measurement of any energy and material flows in a corresponding decentralization.
- this includes heat dissipation from heating systems or the consumption of water, fuels (e.g. natural gas), etc.
- appropriate sensor technology is required on the one hand and the proximity or availability of a suitable component on the other Data transmission network, for example the electrical supply network or a wireless connection in order to forward the data as set out above. Otherwise, the component and the overall system remain unchanged.
- the data can be processed by the central data processing device, e.g. B. the central computer can be processed without further hardware effort.
- FIG. 1 shows a schematic view of a preferred embodiment of a component according to the invention
- Figure 2 is a schematic view of a preferred embodiment of a system according to the invention.
- the component 1 designated as a decembrane in FIG. 1 comprises, in microelectronic integration, four functional components with the following functions: - The energy supply 2 of the components of the component 1;
- the preprocessing means 4 connected to the detection means 3 for preprocessing the raw measurement data and temporarily storing them;
- the communication means 5 for sending the preprocessed measurement data and the address coding via the supply network 6 and for receiving an acknowledgment of receipt for the data sent and possibly other simple data or commands.
- the dimensions of the component 1 are sufficiently small for integration into a conventional socket 8 or a switch housing of the supply network 6.
- the socket 8 has an input 8.1 from the supply network 6 and an output 8.2 to the downstream end user.
- Elements of the supply network 6 such as the socket 8 can be retrofitted or equipped with the component 1 as standard from the factory.
- the components 1 are extremely flexible and can be used with very little effort at any point in the supply network 6, for example office buildings, production sites, the private living environment, etc.
- a variant of the housing 8 consists in the adapter solution.
- the component 1 is integrated into an intermediate plug which is placed between the plug of an end user 10 and an already installed socket.
- Component 1 collects energy consumption data by integrating the power flow with a given temporal resolution.
- the temporal resolution is in the seconds range.
- the measurement values are recorded every one or a few seconds.
- any other clock rates can also be selected, for example in the minute or second range.
- the acquisition and processing means can also be designed for the simultaneous or sequential recording of several variables, such as, for example, current and voltage or pressure and flow rate.
- the built-in processor of the preprocessing means 4 accordingly reduces the amount of data. Averaging of two data points can be carried out in order to make 50% of the memory available again for further data acquisition.
- any other algorithms for data quantity reduction or data compression can also be used in other variants.
- the integration of a separate time measurement into the component 1 does not necessarily have to be provided. Instead, in the case of further processing, for example in a central data processing device, the temporal relationship of the individual measurement points can be inferred on the basis of the number of measurement points transmitted, the time of the previous reading and, if appropriate, a code for the averaging interval used.
- FIG. 2 shows an example of an overall system according to the invention with central data processing in a central data processing device in the form of a central computer 9 and a large number of individual end consumers or end consumption points 10 of a consumption unit 11 of a supply network 6.

- the consumption unit 11 has a first area 11.1, in which a component 1 is provided at each first end consumption point 10.1.
- the consumption unit 11 also has a second area 11.2.

- the second end consumers 10.2 of the not too large end consumer group for example in the form of a lighting system, have a specific consumption behavior, by means of which they can be identified in each case.
- the central computer 9 determines the consumption behavior of the respective second end user 10.2 from the consumption behavior of the consumer group, which was detected by the component 1 arranged at the transition point 12.
- the components 1 do not communicate directly with the central computer 9, which processes the data, but with intermediate stations 13.
- the latter summarize the data from larger groups of components 1.
- the intermediate stations 13 also switch to another data network in the form of an installed digital network.
- the data store in the intermediate station 13 is only deleted when the unit downstream in the overall system, i. H. here the central computer 9 has confirmed receipt of the data.
- the central computer 9 creates a detailed consumption profile of each individual decentralized end user at the end consumption points from the data of the components 1 installed at the end consumption points 10.1 and of the component 1 installed at the transition point 12, wherein, as explained above, it records the consumption behavior of the respective second end consumer 10.2 determined from the consumption behavior, which was detected by the component 1 arranged at the transition point 12.

Let her through the savings potential, which is revealed through the application of the invention, can be identified simply, quickly and specifically and subsequently implemented.
- the central computer 9 creates comparative representations of the consumption development, which can also be queried in real time via the intranet 15 of the organization concerned. It goes without saying that the representations can also be accessed remotely via the Internet. Any section of the created transparency and analysis options can be made available to any target group in the organization or the general public in a timely manner.
