Definitions

  • Temperature control device system with temperature control device and method for changing an operating state of an electronic component
  • the present invention relates to a temperature control device. Furthermore, the invention relates to a system with at least one temperature control device. Finally, the invention relates to a method for changing an operating state of an electronic component.
  • the temperature control device is preferably suitable for controlling the temperature of the air in a room or a medium, e.g. e.g. water. For example, it is an air conditioner.
  • DE 102018 130625 A1 describes a supply network in which loads are switched on individually. For this purpose, one embodiment provides that reservation signals are used.
  • CONFIRMATION COPY The object underlying the invention is to solve the ge in the prior art given problem of simultaneous switching on of several electronic components in a system.
  • the invention solves the problem according to a first teaching by a tempering device.
  • the invention solves the problem with a system with a temperature control device.
  • the invention solves the problem with a method for changing an operating state of an electronic component.
  • the invention solves the problem with a temperature control device with a control unit, with an electronic component, with an energy supply interface and with a communication interface, the electronic component receiving electrical energy via the energy supply interface, the control unit sending and receiving signals via the communication interface, the control unit acts on the electronic component in such a way that an operating state of the electronic component changes, with a change in the operating state at least temporarily leading to a change in the electrical energy requirement of the electronic component, with the control unit for a change in the operating state of the electronic component doing at least the following Executes steps: that the control unit issues an intention signal via the communication interface, that the control unit during a waiting time about the communication s interface receives signals and evaluates whether it is an intention signal from another unit or a change signal from another unit, and that in the event that within the waiting time neither an intention signal from another unit that has a higher priority than the temperature tion device has, nor is there a change signal from another unit, the control unit outputs a change signal via the communication interface and changes the operating state of the electronic component.
  • the temperature control device is an air conditioning system. In an alternative embodiment, it is a heater. In a further embodiment, the temperature control device is a refrigerator.
  • the temperature control device has an electronic component that is characterized, for example, by the fact that it has a high inrush current. she For example, it requires significantly more power when switching on than during operation. In this example, the change in operating state would therefore be switching on the electronic component. Alternatively, the change in the operating status is, for example, the increase in a power level. In general, the changes in operating states that lead to a higher energy requirement during or in a certain time after the change are preferably considered.
  • the temperature control device has a control unit that acts on the electronic component. There is also an energy supply interface and a communication interface.
  • the control unit carries out the following steps using the communication interface:
  • An intention signal (a "request signal”, abbreviated: RS) is output, via which the control unit communicates to all other units which receive signals from the temperature control device that a change in the operating state is intended.
  • the control unit listens for signals via the communication interface, receives signals if necessary and evaluates them.
  • the relevant signals each belong to one of two classes: There can be other intentional signals with which the control units of other units, e.g. B. other temperature control devices their intention to change an operating state of an electronic component. However, there can also be change signals (“turning on signal”, TOS for short) from other units, which communicate that an operating state has already been changed. If there is a change signal, then there is already an increased energy requirement in the system, so that the electronic components of the temperature control device should not experience a change in their operating state during this period. If there is an intention signal from another unit, it is relevant whether the other unit has a higher priority than the temperature control device. If this is the case, the other unit has “priority” and can change an operating state first.
  • the temperature control device can first change the operating state of its electronic component. Overall, the control unit waits for a predetermined waiting time (Tw). Then it changes - after the waiting time Tw - the Operating state of the electronic component when there is no change signal and no intention signal from a higher priority entity. In order to signal that this change is taking place and that no other unit should therefore make a change, the control unit sends out its change signal.
  • Tw waiting time
  • the following configurations relate to the reaction of the temperature control device to intention signals and change signals.
  • One embodiment of the temperature control device provides that if there is an intention signal from another unit and the other unit has a higher priority than the temperature control device, the control unit receives and evaluates signals during the waiting time that begins again.
  • the case is dealt with that the control unit receives an intention signal from a unit that has a higher priority than the temperature control device. This is thus a case in which the tempering device has to wait for the other unit. Provision is therefore made for the control unit to start receiving and evaluating signals again, with the entire waiting time starting again from the beginning in this embodiment. Thus, for example, a counter or timer is reset to zero.
  • An alternative or supplementary embodiment of the temperature control device is that, if a change signal is present, the control unit receives and evaluates signals during the waiting time that begins again.
  • another unit is in the process of changing an operating state of an electronic component, that is to say switching it on, for example.
  • the temperature control device starts the waiting time again and receives signals.
  • the other unit thus has at least the waiting time for the change in operating status.
  • This also results in a criterion for measuring the waiting time. In any case, it should be longer than the time during which the increased energy requirement exists for the units or the temperature control device. Or in other words: After the waiting time, the energy requirement of the electronic components in the system in which the temperature control device and the other unit or units are located should be back to a normal level so that the operating state of the electronic component of the Temperature control device can be changed without overloading the power supply.
  • a further embodiment of the temperature control device provides that the control unit outputs the intention signal multiple times. Alternatively, the intention signal is sent continuously. It is thus ensured in both variants that other units or other temperature control devices, which are connected to the temperature control device via a communication channel, receive the intention signal within the waiting time.
  • the control unit in the event that the control unit outputs the change signal via the communication interface, the control unit also stops outputting the intention signal. Thus, if the control unit makes the change in the operating state and issues a change signal in order to announce this, the intention signal is no longer sent.
  • the temperature control device provides that the control unit outputs the intention signal in such a way that the intention signal has information about the priority of the temperature control device.
  • the temperature control device is associated with a priority.
  • the priority can, for example, be specified at the factory during manufacture or during assembly in an overall system.
  • the control unit outputs information about the priority of the temperature control device with the intention signal, so that other units that receive the intention signal from the temperature control device can determine whether they have to wait for the tempering device or not. This is done depending on their respective priorities.
  • the control unit outputs the change signal multiple times within a starting time and/or with an interval time via the communication interface.
  • the start time is the time that is required for the change in the operating state, for example for starting the electronic component, until the energy requirement has surpassed the initial peak.
  • the temperature control device provides that the temperature control device is designed as an air conditioning system and that the electronic component is a compressor.
  • the compressor is used to compress the coolant and usually requires a very high current when starting up.
  • the invention solves the problem by a system with a temperature control device, with at least one other unit, with a communication channel via which the temperature control device and the at least one other unit transmit signals, and with an energy source that transmits the temperature control device and the at least supplies another unit with electrical energy.
  • the tempering device is designed according to one of the preceding or following configurations. The statements regarding the temperature control device therefore also apply correspondingly to the system with the temperature control device. Therefore, it will not be repeated. Conversely, the explanations and configurations of the system also apply accordingly to the temperature control device as part of the system.
  • the system has several temperature control devices that are designed according to one of the above or following variants.
  • This communication channel is, for example, wired or wireless, e.g. B. realized by radio.
  • the energy source is z. B. realized by a generator or accumulator.
  • the system has a number of air conditioning systems as a temperature control device, as well as other units.
  • This Air conditioners each have a control unit for performing the steps of changing an operational state of an electronic component.
  • the electronic component is a compressor, so changing the operating state is turning on the compressor.
  • the individual air conditioners each have a priority that specifies the order in which the operating status is changed.
  • the tempering devices and the other units synchronize the changing of operating states of electronic components independently and without a central unit.
  • the energy source is therefore only to be designed in such a way that it is sufficient in the event of a change in the operating state of an electronic component. It is not necessary that the capacity for changing the operating state of more than one electronic component can be made available.
  • the invention solves the problem by a method for changing an operating state of an electronic component, with an intention signal being output, with signals being received during a waiting time and evaluated to determine whether it is an intention signal from another unit or from a change signal of another unit, and in the case that there is neither an intention signal of another unit having a higher priority than a unit belonging to the electronic component nor a change signal within the waiting time, a change signal is output and the operating state of the electronic component will be changed.
  • the method thus generally describes the change in an operating state of an electronic component.
  • This is in particular an electronic component that belongs to a device located in a system and that is supplied with other electronic components or devices from a common energy source.
  • this system there is also preferably a common communication channel, so that an exchange of signals can take place.
  • the signal exchange allows synchronization between the devices. Therefore, no central unit as in the prior art is required for this.
  • the statements regarding the temperature control device and the system and the configurations also apply correspondingly to the method. Therefore, a repetition is omitted here.
  • the method can also generally be used in a system be realized electronic components, each belonging to separate units and their changes in operating states are synchronized.
  • the separate units can also all be designed differently from a temperature control device.
  • One variant is, for example, cranes on a shared construction site or washing machines or tumble dryers in a laundromat.
  • Fig. 1 is a schematic representation of a system with a temperature control device
  • Fig. 2 is a schematic representation of a time sequence of a synchronization between two units of a system's.
  • FIG. 1 schematically shows a system 100 with a temperature control device 1 and two other units 2, 3, which are also temperature control units here, for example.
  • Each of the three temperature control devices 1, 2, 3 has a control unit 10, 20, 30 and an electronic component 11, 21, 31.
  • the control units 10, 20, 30 each act on the electronic components 11, 21, 31 with respect to the change of an operating state. Here, for example, this is the starting of the electronic components 11, 21, 31.
  • the temperature control devices 10, 20, 30 in this example shown are air conditioning systems that are distributed in an interior space.
  • the electronic components 11, 21, 31 are each compressors (alternative name: compressor), which compress the coolant used for the cooling process.
  • compressors alternative name: compressor
  • the electric current is provided by a common energy source 5 here.
  • the three temperature control devices 1 , 2 , 3 each have an energy supply interface 12 in order to be connected to the energy source 5 .
  • the control units 10, 20, 30 are specially designed to prevent a plurality of compressors 11, 21, 31 from being started at the same time. This makes it possible to use such a power source 5 that is dimensioned sufficiently to allow a compressor 11, 21, 31 to be started.
  • the energy source 5 therefore does not have to be selected in such a way that the energy can be provided for more than one simultaneous start.
  • no central control unit is required, which controls the individual air conditioning systems 1, 2, 3, since they are synchronized automatically and with one another.
  • a common communication channel 4 is available for synchronization. This can be wired or z. B. be realized via radio.
  • the air conditioners 1, 2, 3 each have a communication interface 13 to send and receive signals.
  • the associated control unit 10 In the event that a compressor 11 of a first air conditioner 1 is to be started, the associated control unit 10 outputs an intention signal RS (for request signal) which carries information about the priority of the first air conditioner 1 . In addition, the control unit 10 listens for a predetermined waiting time Tw whether signals are being transmitted via the communication channel 4 and receives them. The signals received are evaluated to determine whether they are intentional signals RS from other air conditioning systems 2, 3 or change signals TOS (for Turning On Signal).
  • the priority of the air conditioners 2, 3 sending out is derived from these and compared with their own priority.
  • the first air conditioner 1 has a higher priority than the second air conditioner 2 and a lower priority than the third air conditioner 3. If the second air conditioner 2 sends an intention signal RS, this is irrelevant for the first air conditioner 1. However, if the third air conditioner 3 sends an intention signal RS, it is given priority because of the higher priority. As a result, the control unit 10 of the first air conditioning system 1 again receives and evaluates signals for the waiting time Tw. The waiting process for the first air conditioner 1 is thus lengthened.
  • the control unit 10 If the waiting time Tw elapses without an intention signal RS from an air conditioning system with a higher priority and without a change signal TOS, the control unit 10 starts the associated compressor 11 and itself sends a change signal TOS via the communication interface 13 .
  • the time signal curve of two temperature control devices according to the invention is shown as an example.
  • the signals RS and TOS are provided with an index for the respective temperature control device for differentiation.
  • the top row shows the signals of a first temperature control device with a higher priority and the bottom row shows a second temperature control device with a lower priority.
  • Both temperature control devices simultaneously send out their intention signals RS1, RS2 in order to be able to start an electronic component in each case. They then received the intention signals RS2, RS1 of the respective other temperature control device. Since the first temperature control device has the higher priority, it can change the operating state of the electronic component after the waiting time Tw has elapsed. In doing so, it emits a change signal TOS1 during a predetermined starting time Ts.
  • the second temperature control device receives the intention signal RS1 from the first temperature control device and, based on the priority, recognizes that it has to wait again for the waiting time Tw.
  • the intention signal RS1 of the first temperature control device is no longer present, but its change signal TOS1 is present, so that the second temperature control device waits for the waiting time Tw again and receives signals.
  • the change signal TOS1 is no longer present and the second temperature control device waits again for the waiting time Tw. Then it also changes the operating state of the electronic component and sends out its own change signal TOS2 with the interval time Ti.
  • the specified waiting time Tw and the specified start time Ts must be at least long enough for the signals sent in each case (i.e. the request signal or the change signal) - preferably depending on the respective interval time Ti - to can be received and processed by all affected control units. This is therefore also dependent on the properties of the communication channel and the processing speed of the control units.
  • the starting time Ts must be specified at least until the critical inrush current of the affected electronic component has dropped sufficiently and preferably until the electronic component is safely in the changed operating state, ie, for example, has gone into operation.
  • the predetermined interval time Ti is preferably based on the available communication channel. Shorter times Ti increase the reaction speed of the system, but at the same time generate higher communication loads.
