Definitions

  • the invention relates to a device for reading consumption values in a building in particular to heat, water or the like, with at least one consumption value detection device assigned to a consumer and a device for transmitting the determined by the consumption value detection device Consumption values, to a timer device local reception facility of the building.
  • the reading of such consumption value detection devices determined consumption values requires the Access to the location of the respective consumption value recording device, which by the location of the assigned consumer is determined.
  • a remote reading from at least one location outside the individual apartments of the building was tried out.
  • a transfer of the reading data from the individual consumption value recording devices to such a place is a wiring, for example with a two-wire data bus, both from optical problematic as well for cost reasons.
  • any accessible wire connection especially that from the radiator to the wall, a source of manipulation and other disturbances.
  • wireless transmission of the Radio data can be considered.
  • One economically practical application of wireless data transmission in the consumption value acquisition stands in the way of the individual consumption value recording devices on the one hand should be as simple as possible and on the other hand because of their autonomous energy supply by a electrical energy source, i.e. a battery that is operating the consumption value detection device for a very long time To maintain periods of years, very little Energy is available.
  • a call from the consumption value recording devices formed consumption values at a desired reading time, however, would require that each consumption value detection device in addition a transmitter for the consumption values at the same time also one Receivers for an external reading command by which the transmitter in response to an incoming read command transmits the consumption data.
  • This recipient would then have to kept at least in a standby mode to the reading command at the desired reading time to be able to receive. Also a clocked operation of the receiver at fixed intervals, given the long periods of ten years, for example, over which each consumption value recording device operated without changing the battery must exceed the available energy by far.
  • the invention has for its object a device for reading consumption values of the aforementioned Way of creating while maintaining long periods of operation, especially without the need for one Exchange of electrical energy sources, with little structural Effort a remote reading at the desired, fixed reading times can be done.
  • the consumption value detection device has a storage device a timer device for the consumption value recorded in each case and one of their electrical power needs providing internal electrical energy source that the Transmission device as one in the consumption value detection device arranged transmitting device for wireless Transfer of the stored consumption value trained is that the electrical power supply to the transmitter from the timer device each outside the duration of a predetermined time window that is close in time after the key date of a desired billing period lies and in which the consumption value is transmitted, switched off and the transmitter only for the duration of this Time window is activated, and that the local receiving device from their timer setup only during the Duration of the predetermined time window of the transmission device adjusted time window switched to their receiving mode becomes.
  • the local receiving facility itself can be read in an easily accessible place Housing unit or arranged outside the same be so that there the reading by a person reading without Malfunction of the apartment owner can be carried out.
  • the local receiving device can in turn Forwarding of consumption values through a suitable data transmission link over greater distance to a central one Serve data evaluation device. In this case needs then no longer being able to enter the building at all.
  • the time window operation provided in the invention also has the local receiving device uses very little energy. This makes it possible to also use the local receiving device only through an internal, autonomous power source, so a battery to provide energy because that is out electrical power available from such an energy source sufficient to receive during the relationship at very short total operating time.
  • the resulting autonomous energy supply the local receiving device permits their arrangement any suitable place in the building without the Necessity of a network connection. In addition, through this autonomous power supply failure due to power outages or by manipulating an external energy supply avoided.
  • a particularly preferred embodiment consists in that the transmitting device from the timer device in each case in the predetermined time window for transmission of the Consumption value is switched on.
  • each reception capability is targeted the consumption value detection device is dispensed with, so that the latter can be constructed particularly simply can and no electrical energy for a receiving operation necessary is. Rather, the internal Timer device of each consumption value detection device the time of transfer of the consumption value is determined and the sending device only for this purpose and time switched on.
  • each consumption value detection device is admittedly increased by the signal receiver, but the latter can be constructed very simply, since it only the external query signal must record. Because the signal receiver only during the predetermined time window and in there Absence of the interrogation signal only in its standby mode is switched while receiving operation is only switched on when the query signal is received in this way also for the reading device according to the invention achieve significant energy savings.
  • the predetermined time window can be because of the low energy consumption Relative in standby mode spacious, so that even with unavoidable inaccuracies the timer device over the long Operating time through the interrogation signal an exact time of transmission for which consumption values can be set.
  • the timers of both the consumption value detection devices as well as the local receiving device of the building for example, very simply and inexpensively can be stabilized by watch crystals but the inaccuracy over an operating period of years on the order of hours. Because the air time every consumption value detection device for a flawless Reading in the time window of the local concerned Receiver must fall, is therefore sufficient spacious dimensioning of at least the time window of the receiving device required. But the necessary length can be of the time window in an expedient embodiment minimize that the local receiving device a the temporal position of their time window depending on on the timing of a previous transfer of consumption values has matching facility.
  • the local receiving device synchronizes their time window with that of the consumption value recording devices again in each reading period which is due to the temporal transmission relationships of the Consumption values delivered in the previous meter reading period Information. Even if the different ones diverge Time window of both the consumption value detection devices with each other as well as with the local receiving device thus minimizing the need Reach transmission or reception energy.
  • Receivers are not expected to be the individual Consumption value detection devices their stored Consumption values at precisely adhered to times transfer.
  • This probability of interference can be according to an advantageous embodiment thereby reducing it to a negligible small value, that each consumption value detection device within the predetermined time window the transfer of their consumption value repeated at least once and that in the local Receiving device the transfer of the transmitted consumption values only depending on an error check using a verification code.
  • each consumption value detection device an identification number is assigned, each when transferring the consumption values is also transmitted.
  • the local receiving device as a buffer the transmitted data for forwarding to a connected data transmission path to another Evaluation unit is used.
  • each consumption value detection device one controlling their operation Has microprocessor
  • the invention can be particularly simply realize that the consumption value transfer by one from the clock frequency of the microprocessor derived and under program control by the Microprocessor modulated with the respective consumption value Carrier frequency takes place.
  • electronic heat cost allocators are from equipped with a microprocessor from the start. Through the Obtaining the carrier frequency directly from the clock frequency of the Microprocessor and the modulation by software then exists the additional effort for the transmission device only from a transistor and an antenna resonant circuit.
  • the invention provides that the transmitting device as one in each consumption value detection device insertable plug-in module is.
  • Furnishing represents the area of heating billing is the consumption value detection device each by a thermal contact on the surface a radiator arranged electronic heat cost allocator educated.
  • those with the invention achieved advantages particularly clearly. Because the heat cost allocator are arranged on the radiator surfaces, would be a wired transmission of the consumption value one each freely from the radiator through the room to nearest wall extending pipe require what regards operational and counterfeiting security as well is particularly unfavorable for optical reasons.
  • the electromechanical device thus detects any Attempts at manipulation, such as opening or dismantling the Heat cost allocator, and makes such a manipulation attempt through the transmitted one, indicating the fault Signal recognizable.
  • Embodiment is that the electromechanical Setup by a test contact of the heat cost allocator in the closed state of its housing bridging when Opening the housing interrupting conductive rubber part formed and the signal indicating a fault by querying the Test contacts is formed.
  • the lead rubber part as a result a removal of the heat cost allocator from the radiator surface or as a result of an unauthorized opening of the of a front part and a back part facing the radiator composite housing the contact between the Interrupts test contacts, this can easily be done by the Queries, for example at intervals of, for example 0.5 seconds, using the electronics of the heat cost allocator to capture.
  • the interaction of the test contacts with the conductive rubber part are alternatively other options conceivable, for example the suitable arrangement of a microswitch, the switching state changed by manipulation becomes.
  • each consumption value detection device each stored and for transmission intended consumption value is addressed, it must be never just a single value. Much more can this consumption value from a set of several, for example Individual values saved at monthly intervals consist.
  • the wireless reading then not only delivers one the entire accounting period of, for example, one Year reflecting consumption value, but also monthly Basic values so that, for example, if there is a change of tenants a billing period also a proportional billing, for example after months.
  • a two-day Dimensioning the length of the time window according to the meter reading point sufficient timing imprecision of the timers even over a sufficient number of years.
  • the device shown in the drawing for Reading consumption values in a building Consumption amounts have a suitable location of the Building arranged local receiving device 1 to which a number of consumption value detection devices 2, im shown example heat cost allocator, the relative Heat consumption amounts of the radiators corresponding consumption values transmit wirelessly in a manner yet to be explained.
  • these are relative Consumption values from the at a certain point on the radiator surface prevailing temperature determined by which in each case on the surface of the radiator in question Heat contact defined heat cost allocator is measured.
  • Electronics provided in the heat cost allocator for example a microprocessor calculated from the measured temporal temperature curve the consumption value and saves him each in a storage device of the heat cost allocator from.
  • the determined consumption value on a visual display provided on the heat cost allocator 3 displayed.
  • the for the operation of the blocks of the heat cost allocator required electrical energy is provided by a battery arranged in the heat cost allocator, so that it is independent of an external electricity supply is. Because the heat cost allocator over a very long Operating period, in the order of ten years, operational must remain, the one required for its operation Electricity consumption considering the limited capacity the battery should be kept as small as possible.
  • the consumption value detection devices formed by the heat cost allocators 2 each have one Sending device for the respectively saved consumption value on. This transmitter is only within one predetermined time window, which is only one compared to the total operating time has a very short period, each after the key date of a desired billing period, for example of a year, by one in the heat cost allocator provided timer device activated, so that only during this short duration of the time window electrical energy consumption of the transmitting device takes place. Each heat cost allocator transmits within this time window the consumption value stored in its storage device by radio to the local receiving device 1.
  • the lines shown in the drawing between the consumption value detection devices 2, d. H. the heat cost allocators, and the local receiving device 1 therefore not a wire connection, but merely symbolize the radio link.
  • any consumption value detection device could 2 additionally a simple signal receiver included with a standby circuit is provided, which is within the predetermined Time window from the timer in its standby mode is switched.
  • the actual turning on the transmission device of each consumption value detection device 2 can then by a during the period of the standby mode by radio, for example from the suitable equipped local receiving device 1, irradiated Interrogation signal are triggered, causing the transmission time the consumption values within the time window can be controlled from the outside.
  • This one too special type of bidirectional operation can because of Time slot technology used and the measure of the standby mode for a sufficiently long total operating time required energy savings can be achieved.
  • Timers determine the time window Timers, for example by the clock generators from the microprocessors controlling the heat cost allocators are inaccurate, even when stabilized by watch crystals based on the intended years of operation a significant size, for example in the order of magnitude of hours.
  • At least with the purely unidirectional mode of operation can therefore be the exact time of transmission the consumption values are not specified. It can therefore happen that at least two of the consumption value detection devices 2 their consumption values in time Send overlap so that these two consumption values not undisturbed by the local receiving device 1 can be received. Therefore, the ones to be transferred Consumption values from each consumption value detection device 2 within the time window with random time Distribution sent out several times.
  • the local receiving device 1 autonomous by a internal energy source, d. H. a suitable battery with which electrical power required for their operation. This enables in particular their assembly on the suitable locations of the building without the need a network connection and also avoids operational and counterfeit security problems due to interruptions in the external Power supply. Points to the offered energy saving expediently also the local receiving device 1 Timer device through which a the time window of the Consumption value detection devices 2 covering time window is set, the local receiving device 1 only switched to receive mode during this time window becomes.

  • the reader can do this, as in the drawing indicated, also with a suitably trained reading device 4 be equipped in which the transferred consumption values from the local receiving device 1 via a pluggable Cable or wireless, optically or acoustically be read out.
  • This reading device 4 can also with one symbolically indicated by reference number 5 Printer and / or a recording device 6 for recording the consumption values on a data carrier his.

  • the local receiving device 1 for example to protect against anonymous interference, within a closed Housing unit is arranged, there is also a call by radio, the mobile reader 4 of the reader a radio call command from outside the apartment transmits to the local receiving device 1 and the latter a transmission device for further transmission of the in it temporarily stored consumption values for the reading device 4 having.
  • the location of the local receiving device 1 can be the latter also, for example via a bus system, a data network or Radio, within the building to a central receiver 7 be coupled. This measure is particularly useful if there are several local reception facilities within the building 1 are provided.

For example, for manipulation purposes that from a back facing the radiator and a front part facing away from the radiator and housing of the heat cost allocator sealed by a seal for trying to counterfeit consumption be opened. Therefore, the heat cost allocator with one provided electromechanical device in the event of a fault the correct arrangement of the heat cost allocator an electrical signal in thermal contact with the radiator generated and saved, that in the consumption value transmission is also transmitted. This can also be used for remote reading an attempt at forgery can be detected.
