Description

System comprising a plant with a heating system and a device or component, and method for determining an energy consumption of the plant

The present invention relates to a system comprising a system with a heating system and a device or component, and a method for determining an energy consumption of the system, the system for heating the device or component by means of a heated medium transported within the heating system, in particular by means of heated water or steam, is designed and set up, wherein the heating system comprises a supply system, within which the heated medium is supplied to the device or component, wherein the supply system comprises at least one supply system sensor, and wherein the heating system comprises a discharge system, within which a discharge of the Medium takes place from the device or component, wherein the drainage system comprises at least one drainage system sensor.

Such methods are known from the prior art.

For example, patent EP 0 569 837 B1 discloses a device for measuring the efficiency of a steam heater, the steam heater having a steam flow rate sensor for measuring the flow rate of the steam flowing into the device, a steam pressure gauge for measuring the pressure of the steam flowing into the device, and a thermometer for measuring the temperature of the steam. The efficiency of the heat transfer of the steam heater is calculated from the temperature of the material to be heated and the heat quantity of the steam flowing into the steam heater. It is a disadvantage of the prior art that the measurement of the heat efficiency of a steam heater is relatively expensive in terms of equipment. Flow rate sensors in particular are relatively expensive and disproportionately increase the costs and the outlay on equipment for such a device. In particular, when the measurement of such a heating and/or heat transfer efficiency does not have to be observed constantly during operation, but only needs to be checked at regular intervals, for example - for example when a corresponding device is newly set up or such a device is reparameterized the cost-benefit ratio of such sensors is relatively poor.

It is therefore an object of the present invention to provide a method or a device which enables a simpler, less complex and/or more cost-effective measurement of a thermal efficiency of a steam heating system.

This object is solved by a system having the features of patent claim 1 .

Such a system comprises a plant, the plant also comprising a heating system and a device or component.

The system is designed and set up for heating the device or component by means of a heated medium transported within the heating system, in particular by means of heated water or steam.

The heating zsystem comprises a supply system, within which a supply of the heated medium to the device or Component takes place, wherein the delivery system comprises at least one delivery system sensor.

In addition, the heating system includes a removal system within which the medium is removed from the device or component, the removal system including at least one removal system sensor.

The fact that the system includes a computer device which is designed and set up for simulating the heating system makes it possible to simulate the behavior of the heating system, in particular in conjunction with the device or component, in parallel with a real heating system or to simulate the process running in the plant . An energy flow or an energy flow of a steam flowing in the heating system can be determined without having to install a corresponding apparatus-based sensor system in the system. This simplifies the measurement of energy consumption, energy efficiency and/or energy flow in such a heating system and/or makes a corresponding determination of such variables more cost-effective. The system for heating the device or component is designed and set up by means of the heating system and includes the essential components required for this, in particular the system, consisting of the device or component and the heating system. Furthermore, the system can include a control device for controlling the device or component and/or the heating system.

The heating system can be designed and set up, for example, as a circulatory system. include such a circulatory system. In such a circulatory system, a media heating unit can be provided, for example, which heats the heated medium used to heat the device or component and feeds it into a corresponding line system of the system with, for example, a predetermined temperature and a predetermined or specifiable pressure Hei zsystems, such as the supply system feeds. Furthermore, the circulatory system can then be designed and set up in such a way that the medium discharged from the device or component in the discharge system is completely or partially returned to the medium heating unit. This return of the discharged medium can, for example, take place at least partially via the discharge system.

The medium used in the heating system can be any liquid or gas suitable for heating and transport to the device or component. In particular, the gas can be water vapor or nitrogen, for example. The liquid can be water, for example. It may be necessary for the transport of the gas or the liquid to have a specific pressure or pressure range and/or a specific temperature or a specific temperature range in the heating system. present .

The supply system includes, for example, all components that are necessary, necessary and/or advantageously present or must be present for transporting the heated medium to the device or component. This can be, for example, corresponding media sources, pipelines, hoses, pumps, valves, sensors, vessels, rooms, flanges, coupling pieces, seals and/or similar components or parts. In this case, such components or parts or their transitions must be designed and set up for the temperatures and pressures present in the heating system.

In such a case, such a central heating device of the heating system can be assigned to both the supply system and the discharge system. A corresponding suction device can also be assigned to the discharge system.

The at least one discharge system sensor is z. B. designed and set up in such a way that using appropriate sensor data a simulation of a media flow is possible in at least one area of the supply system, several areas of the discharge system or even all areas of the discharge system.

The at least one feed system sensor and/or the at least one discharge system sensor can e.g. B. be designed and set up in each case as a temperature, pressure and/or valve position sensor, it also being possible for a valve position to be determined indirectly using a valve control. In the context of this description, this is also understood as a valve position sensor.

Furthermore, the at least one feed system sensor and or the at least one discharge system sensor z. B. be designed and set up in each case as a flow, flow and/or energy flow sensor. However, such sensors are generally rarely used in such heating systems since they are comparatively expensive and are often not absolutely necessary for a corresponding functional control and/or regulation of the heating system.

The computer device can be any computer device that has sufficient memory and computing capacity to simulate the heating system and to determine energy inflow information and/or energy outflow information and/or energy consumption information. In particular, the computer device can be, for example, a PC, a workstation, a computer network, a cloud, a control device, a controller, a programmable logic controller, a modular programmable logic controller or a comparable device. Furthermore, the computer device can be designed and set up, for example, as a so-called edge device. The computer device can also ner hardware, a computer or part of a computing network, or for example an application in a cloud or in a computer network or a corresponding server or computing device.

For example, the computer device can be a control device or be a control computer - or a part or Module thereof - which at least among other things controls the heating system and / or regulates. Furthermore, the computer device can also be used as a device with such a control device or Control computer coupled edge device be designed and set up.

A computer device can e.g. B. also be designed and set up as a virtual computer device instance, the z. B. runs or can run on appropriate hardware, an appropriate computer network or a cloud. In this case, when the virtual computer device instance expires, e.g. B. on said hardware that generates the functionality of the computing device.

The computer device can also be composed of several sub-devices. These can be communicatively coupled, for example. Each of the sub-devices can then in turn be designed and set up according to the design options explained above for a computer device.

The computer device can also be designed and set up in such a way that the data fed to it from the at least one supply system sensor and/or the at least one discharge system sensor can be used directly or indirectly to determine energy inflow information and/or energy outflow information and /or an energy consumption Information can be used as an input. So e.g. B. an energy inflow value can be determined by means of data from the at least one supply system sensor and z. B. by means of data from the at least one discharge system sensor, an energy outflow value and by forming the difference between the energy inflow value and the energy outflow value, an energy consumption value is then determined.

Furthermore, the computer device can be designed and set up to process or further process the data supplied to it by the at least one feed system sensor and/or the at least one discharge system sensor. Such processing or further processing can, for. B. be or include a standardization, conversion, transformation, reformatting, translation and/or other comparable processing step.

The computer device can be designed and set up in such a way that after processing or further processing of the data supplied to it by the at least one feed system sensor and/or the at least one discharge system sensor, one or more results of such processing or further processing can be determined directly or indirectly energy inflow information and/or energy outflow information and/or energy consumption information can be used as an input variable.

The computer device can also include, for example, a simulation environment and/or a digital twin that is used to run a simulation program for simulating a system according to the present description, a plant according to the present description and/or a heating system and/or a component according to the present description are trained and set up or can be no . The computer device can furthermore also include a simulation environment with a simulation program for simulating a system according to the present description, a plant according to the present description and/or a heating system and/or a component according to the present description.

The computer device can also be designed and set up to transfer, transmit and/or output information relating to the energy supply information and/or energy drain information and/or energy consumption information to a further data processing device. Such a data processing device can be, for example, an operator input/output device (a so-called “HMI” (Human Machine Interface)), a control device, for example for controlling the system and/or the heating system, an edge device, a cloud or a other data processing equipment, e.g. B. for storage, output, archiving o . uh . , be .

Furthermore, the information mentioned can also be or include information evaluating the information mentioned, such as a warning message or a message that, for example, determined values are within the framework of certain specifications, or similar information.

The simulation of the heating system can be designed and set up in such a way that, for example, a line system of the heating system with corresponding pipe or hose lengths and cross-sections, valves, sensors, heat transfer (in for example to the device or component) to the output of the heating system, for example a return to a central heating or another media output, is simulated. For example, at least one pressure and/or at least one temperature of the heated medium at an input area of the heating system, for example an output of a corresponding media heater, or also comparable process parameters can serve as input variables for such a simulation. Furthermore, data from other sensors and component data within the heating system, for example valve positions, temperatures and/or pressures at other points within the heating system, temperatures for example also at the device or component to be heated, and also in the discharge area of the heating system , can be used to simulate the heating system - or other process parameters. As a rule, the more such sensors in the real system to be simulated are used as input variables for a simulation of this system, the higher quality and more accurate the simulation of the heating system becomes.

Furthermore, the simulation of the heating system can be designed and set up in such a way that, for example, a temperature, a pressure, a flow rate, an energy flow and/or other process parameters of the medium and/or the heating system itself are measured at various points of the heating system as part of the simulation is determined or is determinable. The simulation of the heating system can also be designed and set up in such a way that this data can be determined or is determined, for example, at all essential points or in all essential areas or in all areas of the heating system. The simulation of the heating system can also be designed and set up in such a way that the simulation can be carried out or is carried out in parallel with a real process or procedure running within the heating system and/or the device or component, i. H . that the simulation of the heating system essentially simulates or simulates the current states within the heating system and/or the device or component at any time. calculated . In this way, the simulation can also be used, for example, to determine variables, measured values and/or states within the heating system and/or the device or component that cannot be determined in the real system, only with difficulty or only with relatively great effort, since, for example, at corresponding If there are no sensors or no sensors can be attached or there are no suitable sensors for the corresponding measured variables - or a corresponding sensor system would be too expensive or would be too complex to install.

The determination of such process parameters in the context of a process parallel to a simulation of this process is z. B. also referred to as virtual sensors. A corresponding determination of a specific process parameter within the scope of such a simulation is then referred to, for example, as a so-called virtual sensor for this process parameter or also a soft sensor for this process parameter.

By such parallel to the real conditions in the heating system or. By simulating the device or component, it is possible to monitor the heating system during operation better, more precisely and/or more flexibly with less technical effort. For example, sensor values can be flexibly simulated or calculated at different points in the heating system within the simulation. be determined without real len system to have to attach appropriate sensors to these respective locations.

This also simplifies and facilitates, for example, troubleshooting in the event of faults within the heating system, since troubleshooting or a search for the causes of such a fault is simpler and/or possibly easier to carry out.

The energy supply information can be or include, for example, any information which is characterized by an energy flowing through a specific section of the supply system. The section of the supply system can be, for example, a line, pipe and/or hose cross-section within the supply system. The information can be, for example, an amount of media flowing through such a section per unit of time, an energy or amount of energy per unit of time, a temperature and/or a pressure of a media flowing through such a section, one or more physical measured variables which indicate an energy flow or a material flow or Describe media flow or comparable information.

For example, energy supply information can be or include media flow information relating to the medium flowing through a specific section per unit of time plus, for example, a temperature and/or a pressure of this medium. Furthermore, the energy supply information can also directly include one or more physical variables that characterize or describe an energy flowing through a section per unit of time. An energy of the heated medium, for example, z. B. as an absolute energy value or in relation to an energy of an unheated medium and/or an energy, for example, of a medium returned by the device or component, for example in the discharge system.

The energy consumption information can, for example, be in the form of information relating to a difference in media energy supplied to the device or component by means of the heating system, e.g. B. via the supply system, and a media energy discharged from the device or component, e.g. B. about the drainage system, be trained and set up. Such information can be designed and set up, for example, as a physical variable relating to a difference between an amount of energy supplied and an amount of energy removed or also relating to a difference between an energy flow supplied or a corresponding heat output and an energy flow removed or a corresponding heat output.

A heat output is understood here as a heat energy measured per unit of time.

Furthermore, the energy inflow, the energy outflow and/or the energy consumption information can each also be qualitative litative resp. include evaluating information or meta-information.

In doing so, qualitative or Evaluating information, for example, information about whether a specific energy flow or energy consumption is within an expected range or is higher or lower. Such qualitative information can then be output to a user or an HMI, for example, at least by means of the computer device, for example, in order to facilitate monitoring of the heating system, for example.

Meta information relating to the energy information transmitted in each case can be, for example, further physical state variables within the heating system, information relating to an operating state of the heating system and/or the device or component and/or a heating device for the heating medium or comparable information. Furthermore, meta information z. B. This can also include information about the device or component used or the heating system.

The computer device can be designed and set up to output or communicate the energy inflow information, the energy outflow information and/or the energy consumption information, for example to an HMI, a user, a further data processing device, a database, a control device (e.g. B. for the heating system and/or the plant and/or the device or component), or comparable facilities. In this case, for example, such an output or communication for output to a user, for archiving, for controlling the heating system and/or the device or component or of the plant or similar purposes. In an advantageous embodiment, it can be provided that the heating system does not include an energy flow sensor or comparable sensor for measuring an energy flow or energy flow caused by a media flow guided through the heating system. Furthermore, it can be provided that the heating system does not include a flow sensor or comparable sensor for measuring a media flow guided through the heating system.

In a further advantageous embodiment it can be provided that the at least one supply system sensor comprises a supply temperature sensor and/or a supply pressure sensor and the at least one discharge system sensor comprises a discharge pressure sensor, the computer device for determining the energy supply f Flow information and/or the energy flow flow information and/or the energy consumption information is formed and set up using data from the supply temperature sensor, the supply pressure sensor and/or the discharge pressure sensor.

Within the scope of this configuration, it can be provided that a simulation of the heating system is carried out by the computer device using a supply temperature sensor and/or a supply pressure sensor and a discharge pressure sensor. Within the framework of such a simulation, for example, the energy inflow information, the energy outflow information and/or the energy consumption information can then be determined by determining corresponding physical variables using the simulation.

In a further advantageous embodiment can be provided, for example, that the heating system by means one or more supply temperature sensors and one or more supply pressure sensors and one or more discharge pressure sensors are each simulated as input parameters for the simulation. On the basis of this simulation, the computer device can then in turn, for example, determine and optionally output energy inflow information according to the present description, energy outflow information according to the present description and/or energy consumption information according to the present description.

This configuration has the advantage that physically in the heating system comparatively few sensors have to be provided in order to determine the corresponding information. Furthermore, the temperature and pressure sensors in particular are generally among those sensors which are required as standard anyway for the operation of such a heating system and which must already be provided for normal operation.

Therefore, this refinement enables a further simpler, less complex and/or more cost-effective measurement of a thermal efficiency of the heating system and/or the installation.

Provision can furthermore be made for the computer device to include a digital twin of the installation or the heating system and/or to be designed and set up to simulate the installation or the heating system.

This configuration makes it possible, for example, for the computer device to simulate the entire system in addition to simulating the heating system, and thus in particular the effects of the device or component on an energy balance during heating of the device or Components can be better taken into account by means of the heating system.

The use of a digital twin within the framework of a system according to the present description also enables access to a large number of data, parameters and parameters relating to the system or the heating system, which determine the corresponding energy inflow, energy outflow and/or energy consumption - Information improved and/or simplified.

The digital twin can, for example, be designed and set up as a computer program product or include one that at least simulates the plant and/or the heating system and/or the device or component, among other things, when running on a computer device. Furthermore, the digital twin can include other parameters, data, status variables, meta-information, design and installation information and other information relating to the system and/or the heating system.

In general, a digital twin, e.g. B. for a particular asset, denotes a collection of digital information related to that asset.

The digital twin can include, for example, a plant design, a plant plan, plant parameters or comparable information characterizing a plant.

The digital twin can also include information relating to the current status of the system, for example current status parameters or physical measurement parameters relating to the system, operating parameters and/or information naming with regard to an operating state of the plant, or comparable parameters or information.

Furthermore, the digital twin can include a simulation of the system, which makes it possible to simulate the system - for example in real time, or also independently of a corresponding real system. The simulation z. B. be designed and set up in such a way that such a simulation of the system takes place or can take place in parallel with operation of the corresponding real plant in such a way that current state or physical parameters of the real plant are used as input variables for such a simulation. In this case, the simulation can at least essentially describe or represent a current operating state or state of the plant.

The simulation can be designed and set up as a computer program product, for example, which generates the corresponding simulation when running on a computer. The above-mentioned additional parameters, measurement data and other variables that characterize the system can be or will be stored, for example, in a database as part of the digital twin. Plans and the like relating to the installation can also be stored in such a database in the digital twin of the installation.

In an advantageous embodiment, it can also be provided that the digital twin and/or the simulation of the system or the heating system includes a virtual energy flow sensor, and/or that the digital twin and/or the simulation of the system or the heating system Simulation of an energy flow is designed and set up. This configuration enables a simpler and also less complex determination of a heat efficiency for the heating system, since the use of the digital twin or the simulation of the energy flow, the desired information, can be determined directly or is determined.

The virtual energy flow sensor can, for example, be designed and set up in such a way that the computer device, for example as part of a simulation of the heating system, generates a physical parameter for an energy flow in one or more specific areas of the heating system and/or within a specific Pipe or line cross-section in the heating system or in the supply system or discharge system is calculated. Such a parameter can be, for example, a media flow or a media flow density within a specific area or cross section of the heating system, for example together with a corresponding temperature of the heating medium. Such a parameter can also directly be an energy flow through a certain pipe or line cross section or pipe or line area, or also an energy flow through a certain pipe or line cross section or pipe or line area. Such an energy flow can, for example, be in energy per unit of time, ie z. B. in watts.

The simulation of the energy flow can, for example, be designed and set up in such a way that, as part of the simulation of the heating system, an energy flow according to the present description can be determined or is determined by the simulation in at least one area, in several areas or advantageously in all areas of the simulated heating system becomes . If, for example, it is determined during the simulation of the heating system at a specific point or a specific cross section of the simulated heating system in the simulation that the energy flow is to be determined or is being determined at this point or cross section, this determination is made within the simulation program or within the simulation of the heating system as a so-called virtual sensor, in this case a virtual energy flow sensor.

The system, the facility and/or the heating system can also comprise a control device, the computer device being designed and set up to transmit the energy supply information and/or the energy outflow information and/or the energy consumption information to the control device, wherein the control device is designed and set up to take into account the energy supply information and/or the energy drain information and/or the energy consumption information as part of the control of the system or of the heating system.

This advantageous embodiment makes it possible to take into account the ascertained energy inflow information, energy outflow information and/or energy consumption information directly when controlling the installation and/or the heating system. In this way it can be achieved, for example, that the heating system or the entire system is always in a predetermined or specifiable energy consumption state. As soon as the ascertained energy inflow information, energy outflow information and/or energy consumption information shows that more energy is being consumed than specified within the scope of the operation of the system and/or the heating system, appropriate Appropriate by the controller in the course of a control program for controlling the system and / or the heating system are counteracted accordingly.

The control device can be any type of computer or computer system which is designed and set up to control a plant, a device, an apparatus or a device. The control device can also be a computer, a computer system or a so-called cloud on which control software or a control software application, for example a control application, is implemented or. is installed . Such a control application implemented in the cloud can e.g. B. be designed and set up as an application with the functionality of a programmable logic controller or a comparable control device.

For example, such an application can be designed and set up as an application with the functionality of a programmable logic controller or a comparable controller. The edge device can be connected, for example, to a further control device for a device or system, or also directly to a device or system to be controlled. Furthermore, the edge device can be designed and set up in such a way that it is additionally connected to a data network or a cloud, or is designed and set up for connection to a corresponding data network or a corresponding cloud. The control device can, for example, also be designed and set up as a so-called programmable logic controller (PLC).

Such steam heating systems are often relatively large and extensive and require a relatively large supply of energy. Therefore, a system according to the present description, or also a method according to the present description, particularly advantageous in these cases, since in this way a possibility ness provided , a significant energy saving may be achieved .

Since it is a system according to the present description or a method according to the present description enables energy consumption information to be made available without having to install a separate sensor system in addition to the sensors already present in the system, are applications of such a system or Such a process is particularly attractive in the field of tire production and brewing.

A tire heating press device, also referred to as a vulcanizing press or "curing press", is understood to mean a machine or system which is designed and set up for vulcanizing vehicle tires. This step in the process of manufacturing a vehicle tire involves a hardening process in which the corresponding vehicle tire is given its final shape. In this curing process, it is vulcanized for a specific time at a specific pressure and temperature. During this step, the raw rubber is transformed into flexible and elastic rubber. In addition, the tire receives a corresponding form of vulcanizing press or the tire heating press its profile and sidewall markings.

Such a vulcanizing press usually includes one or two molds, each of which can accommodate a so-called green tire. Such a vulcanizing press usually includes line systems for hot gases, liquids or vacuum as well as conveyor belts for transporting the green tires in and out as well as the finished vulcanized vehicle tires. As part of a vulcanizing process for a green tire in such a tire heating and pressing device, what is known as a bladder is then usually introduced into the interior of the green tire, similar to a bicycle tube, and then a hot gas or hot liquid is placed under this bladder high pressure. In this way, the heating bladder presses the green tire into the mold (e.g. tire tread and lettering are embossed) and continues to trigger the vulcanization process of the tire through the high temperature. After the vulcanization process, the now vulcanized vehicle tire is removed from the appropriate mold and fed to the next process step in tire manufacture.

The bladder (also referred to as "bladder" or "tire curing bladder" in English) is designed and configured as an elastic bladder (e.g. made of rubber or a comparable material) which is inflated or expanded by means of the supply of a gas or a liquid, and can be expanded by means of discharging and/or sucking off gas contained therein or liquid contained therein. In this case, the heating bladder can be designed and set up, for example, in such a way that it can be expanded or expands when it is filled with a gas or a liquid, and contracts or can be contracted again accordingly when it is emptied.

The heating bladder can, for example, also be designed and set up in such a way that the gas or liquid that can be supplied or supplied can have temperatures of up to 100 degrees Celsius, advantageously of up to 200 degrees Celsius and further advantageously at 250 degrees Celsius . The heating bladder can also be designed and set up in such a way that, for example, heated air, heated water vapor, nitrogen and/or other gases—including those with the temperatures mentioned above—can be supplied as gases. Heated water, for example, is often used as the liquid.

The heating bladder can be designed and set up in such a way that, at least inside a green tire, it can withstand a pressure of up to 30 bar or more, or a vacuum of up to -1 bar.

Monitoring the heating bladder plays a special role in monitoring a vulcanization process in a tire heating press device. For example, cracks and/or leaks in the material of the bladder can cause hot gas or hot liquid to enter the space between the bladder and the green tire, causing the vehicle tire produced to become defective. If such a crack or defect in the bladder is detected too late, for example, this can lead to a larger quantity of unusable vehicle tires being produced in the tire heating press device.

It is therefore advantageous to detect such damage in a bladder at an early stage or, even better, to determine before the actual defect occurs that such damage will occur in the near future. This can be done, for example, by already detecting corresponding precursors of such a defect, for example corresponding microcracks. Such leaks and microcracks in a heating bladder can also be recognized, for example, by an increasing energy consumption of a corresponding heating system for the heating bladder. Here, a system or method according to the present the description provide a simpler, more effective or cheaper way to determine such an increasing energy consumption in the heating system compared to the prior art.

The above-mentioned object is also achieved by a method for determining an energy consumption of a plant according to the present description with a heating system according to the present description, comprising the steps:

- Transmission of data from the at least one supply system sensor and/or the at least one discharge system sensor to the computer device,

- Simulating an inflow of energy generated by an inflow of the heated medium to the device or component, and/or simulating an outflow of energy generated by an outflow of the medium from the device or component,

- Determination of the energy inflow information and/or the energy outflow information and/or the energy consumption information.

The heating system, the at least one supply system sensor, the at least one discharge system sensor, the computer device, the simulation, the determination of the energy inflow information, the energy outflow information and/or the energy consumption information according to the present description be trained and set up.

Furthermore, the simulation of the energy inflow generated by an inflow of the heated medium to the device or component, as well as the simulation of the energy outflow generated by an outflow of the medium from the device or component, can be designed and set up according to the present description. The method can also be designed and set up in such a way that the energy inflow information and/or the energy outflow information and/or the energy consumption information to a control device for the system and/or the heating system for influencing the control of the system or of the heating system is transmitted.

The transmission of the energy supply information and/or the energy dissipation information and/or the energy consumption information to the control device for the system and/or the heating system can influence the control of the system or the heating system according to the present description be trained and set up.

Further advantageous configurations can be found in the dependent claims.

These can be heated via a heating system using hot steam. For ease of illustration, the upper and lower molds, the green tire, and the heating system for the molds are not shown in FIG.

To support the vulcanization of the green tire, the tire curing press 100 also includes a heating bladder 114, which is shown schematically in FIG. As part of the vulcanizing process of the green tire, the heating bladder 114 is filled with hot steam under high pressure, expands inside the respective green tire and in this way presses it against the lower or upper tire mold. In this way, in addition to the actual vulcanization of the tire material, a tire profile and also other relief-like structures of the vehicle tire are embossed into the green tire.

The hot steam mentioned here for filling and heating the heating bladder 114 is just one example of the wide variety of gases or liquids that can be used in such tire heating/pressing devices 100 . During the vulcanization process, these can have temperatures of up to 100 degrees Celsius, advantageously of up to 200 degrees Celsius and furthermore advantageously of up to 250 or 300 degrees Celsius. The heating bladder 114 and the corresponding media system 102 can also be designed and set up in such a way that, for example, air, steam, nitrogen and/or other gases—including those with the temperatures mentioned above—can be used as gaseous media. If, for example, liquid media are to be used instead, heated water is often used.

The heating bladder 114 can be designed and set up in such a way that, at least inside a green tire, it can withstand a pressure of up to 30 bar or more, or a vacuum of up to -1 bar.

FIG. 1 also shows the steam media system 102 for filling and emptying the bladder 114 with hot steam and/or other heated gases or liquids. This media system 102 can, for example, also be designed and set up for the pressure and temperature ranges mentioned above.

After the main outlet line 260 from the outlet line 240, a vacuum line 250 with an on-off valve 350 is provided, via which gases or liquids contained in the heating bladder 114, for example, can be actively sucked out.

To measure the at the end of

Suction line 450 present pressure and the present there A pressure sensor 476 and a temperature sensor 474 are fitted there to measure the temperature.

The main outlet line 260 , the outlet line 240 and the vacuum line 250 are part of a discharge area 106 for discharging the heating medium from the heating bladder 114 . The discharge area 106 is an exemplary embodiment of a discharge system according to the present description.

The water vapor media system 102 also includes a steam generation system 108 for heating the water vapor and feeding the heated water vapor into the inflow lines 210 , 220 of the feed area 104 under the respectively provided pressure. A temperature sensor 464 and a pressure sensor 466 are provided on the first inflow line in order to measure the inlet temperature and the inlet pressure of the water vapor fed into the first inflow line by the steam generation system. Furthermore, a temperature sensor 460 and a pressure sensor 462 are provided on the second inflow line in order to measure the inlet temperature and the inlet pressure of the water vapor fed into the second inflow line by the steam generation system.

Furthermore, at least a portion of the water vapor removed from the bladder 114 is routed back to the vapor generation system 108 via the outlet line 240 to be reheated there and then returned to the feed region 104 . A temperature sensor 470 and a pressure sensor 472 are mounted there to measure temperature and pressure at the corresponding inlet of the steam generation system 108 .

The steam generating system 108 is in the present embodiment example as both the supply area 104 and the Discharge area 106 of the water vapor media system 102 considered associated.

Furthermore, a control device 130 is shown in FIG.

Corresponding signal output lines go from the input/output modules 134, 136 to the various valves 310, 320, 322, 321, 330, 335, 370, 360, 340, 350 of the media system 102. Control signals can be transmitted via these signal output lines are transmitted from the central module 132 of the control device 130 to the aforementioned valves 310, 320, 322, 321, 330, 335, 370, 360, 340, 350 in order to set corresponding valve positions.

Furthermore, corresponding signal input lines go from the temperature sensors 450, 460, 464, 470, 474 and the pressure sensors 410, 420, 430, 440, 462, 466, 472, 476 to the input-output modules 134, 136 to the corresponding To transmit sensor values to the central module 132 of the control device 130 .

This is symbolized in FIG. 1 by naming the reference numbers of the corresponding valves and sensors below the output and input lines symbolically shown below the controller 130 .

A runtime environment for a corresponding control program for controlling the tire curing press 100 is provided in the central module 132 . In order to vulcanize a green tire placed in the right part of the tire heating press 100, For example, as part of the execution of this control program by means of the incoming sensor signals and the outgoing control signals for corresponding valves 310, 320, 322, 324, 330, 335, 370, 360, 340, 350 a gas inflow and gas outflow for proper support of the vulcanization process being controlled. In this way, the vulcanizing process of the green tire 116 is correspondingly supported by a corresponding inflow and outflow of heated water vapor into and out of the heating bladder 114.

An edge device 500 is also shown in FIG. The edge device 500 includes a digital twin 502 of the tire curing press 100, which in turn includes, among other things, a simulation 504 of the water vapor media system 102 along with the bladder 114. In this case, the edge device 500 is an exemplary embodiment for a computer device according to the present description and the digital twin and the simulation are each an exemplary embodiment for a digital twin or a simulation according to the present description.

This edge device 500 is connected to the control device 130 via a fieldbus line 139 . For example, control commands that are used to control the tire curing press 100 can be transmitted to the evaluation device via this field bus line. Furthermore, position information of the valves 310, 320, 322, 324, 330, 335, 370, 360, 340, 350 of the media system 102 can be transmitted to the edge device 500 via the fieldbus line 139. The control device can also use this fieldbus line to transmit measured values from temperature sensors 450, 460, 464, 470, 474 and pressure sensors 410, 420, 430, 440, 462, 466, 472, 476 to the edge device. The control device 130 and the simulation 504 of the heating system 102 with the heating bladder 114 are designed and set up in such a way that the above-mentioned valve position information and sensor values are regularly (e.g. Ix per program cycle of a control program, 1 time per tenth of a second, 1 time per second, 1 times per minute, ...) from the control device to the edge device via the fieldbus line 139. A water vapor flow in the supply area 104 and discharge area 106 of the water vapor media system 102 is then simulated within the simulation 504 using pressure and temperature values in the input lines 210 , 220 and the output lines 240 , 250 .

In an advantageous embodiment of the simulation, the pressure in the heating bladder, which is supplied by the associated pressure sensors 410, 420, which are positioned directly at the outlet of the heating bladder 114, is also included in the simulation.

In addition, pressure values from pressure sensors 430, 440 in discharge area 106 of heating system 102 can also be used for the simulation.

As a rule, a simulation of the heating system 102 becomes better and better, or the simulation results correspond better and better to the actual conditions in the heating system 102, the more sensor values from the real heating system 102 are used as input variables for the simulation 504.

As part of controlling the media system 102 with the control device 130, the position values of the valves 310, 320, 322, 324, 330, 335, 370, 360, 340, 350 of the media system 102 and the sensors are then regularly/constantly during the production of vehicle grips 450, 460, 464, 470, 474, 410, 420, 430, 440, 462, 466, 472, 476 of the media system 102 are transmitted to the edge device 500 and entered there as input variables into the simulation 504 as described above.

The simulation 504 is designed and set up in such a way that it uses so-called soft sensors 580, 581, 582, 583, 584, 585, 586, 587, 588 (see Figure 2) to determine and output state parameters of the water vapor in the supply area 104 and discharge area 106. Such state parameters are e.g. a temperature, a pressure and an energy flow. This is explained in more detail in connection with FIG.

Edge device 500 is also designed and set up in such a way that energy consumption or energy loss in the context of heating bladder 114 is determined from the energy inflows determined by the simulation in the inflow area 104 and the energy outflows in the discharge area 106 determined by the simulation determine. This can be carried out, for example, by calculating the difference between the energy flow supplied and the energy flow removed, or also by calculating the difference between an amount of energy supplied over a certain period of time and an amount of energy removed over a certain period of time.

This information is determined, for example, in a cycle of the supplied data and is transmitted, for example, to an HMI system 600 via an OPC UA communication link 602 in order to output it to a system operator for monitoring purposes. Furthermore, the energy consumption information is transmitted back to the control device 130 in order to react, for example, to increasing energy consumption when controlling the water vapor media system 102 and, for example, to control the valves 310, 320, 322, 324, 330, 335, 370, 360, 340, 350 accordingly in order to reduce the energy consumption during the steam heating of the heating bladder 114 back to a predefinable or predetermined consumption value.

FIG. 2 shows a simulation model 504 which includes a simulation model of the heating system 102 shown in FIG. 1 together with a simulation model 514 of the heating bladder 114 also shown in FIG.

The simulation model 504 contains an image of the supply area 104 of the heating system 102 with the two inflow lines 210 , 220 and simulations 510 , 520 of the on-off valves 310 , 320 contained in the inflow lines 210 , 220 of the real heating system 102 . Furthermore, the simulation model 504 in the supply area 104 also contains a simulation of the control valve 522 and the safety valve 521 and also a simulation of the main inlet valve 570 .

The values determined by the temperature sensor 464 and pressure sensor 466 in the real inflow line 210 of the real heating system 102 are used as input values for the water vapor in the left, first inflow line 210 , which is entered symbolically according to the simulation model 504 . Correspondingly, the values of the temperature sensor 460 and the pressure sensor 462 from the real heating system 102 are used for the right inflow line 220 as input values for the inflowing hot steam. This is also correspondingly symbolically entered in FIG.

In the simulation 504, corresponding length and cross-section information is assigned to the corresponding connecting lines or supply lines of the supply area 104 in order to be able to realistically calculate corresponding flows and pressure conditions in the simulation. The simulation model further includes a simulation of the bladder 514 including a simulation of its corresponding thermal properties. The pressure measured in the real heating bladder 114 and supplied by the corresponding pressure sensor 420 and the temperature measured by the temperature sensor 450 in the heating bladder are used as input variables for the simulation of the heating bladder 514 as the basis of the simulation 504 .

The simulation model 504 also contains an image of the discharge area 106 with a simulation 560 of the real main outlet valve 360 according to FIG.

The values of the pressure sensor 472 and temperature sensor 470 in the left outlet line 240 and the values of the pressure sensor 476 and temperature sensor 474 in the right outlet line 250 are used as the input value for the simulation model 504, which is also shown symbolically in FIG.

Furthermore, the simulation model 504 includes virtual energy flow or Power sensors 580, 583, 586. These virtual energy flow sensors 580, 583, 586 each supply an energy flow value or Power value for the steam energy flowing through the corresponding pipe cross-section at this point. This can be done by means of the simulation, for example using a steam temperature calculated at this point as part of the simulation, a corresponding specific heat capacity of the Water vapor and a flow rate of the steam passing through this tube cross-section can be determined.

In a corresponding manner, the simulation model 504 also includes three virtual temperature sensors 581 , 584 , 587 , which are each used as output values within the framework of the simulation at this point in the feed area 104 or Discharge area 106 outputs determined water vapor temperature. Furthermore, the simulation model accordingly also includes three virtual pressure sensors 582, 585, 588, which each have one at the corresponding point in the supply area 104 or Discharge area 106 outputs calculated pressure of the water vapor as part of the simulation at this point.

Furthermore, the digital twin 502 (see FIG. 1) or the simulation 504 within the digital twin 502 be designed and set up in such a way, for example, that an overall energy inflow value , which is formed from a sum of the virtual energy flow sensor 580 in the left inflow line 210 and the virtual energy flow sensor 583 in the right inflow line 220, to the HMI 600 is output. Furthermore, the value of the virtual energy flow sensor 586 in the left outlet line 240 can also be output to the HMI 600 as an energy discharge.

In a further advantageous embodiment, the difference between the energy inflow according to the above description and the energy outflow according to the above description can also be output to the HMI 600 as energy consumption information.

The energy inflow value, the energy outflow value and the energy consumption value explained above are examples of energy inflow information, energy outflow information Information and energy consumption information according to the present description.

This information mentioned can include, for example, further information, such as a date and time of the respective determination of this value, an identifier for a system to which these values can be assigned or are assigned, an identifier or ID or a file name of the simulation model, on the basis of which these values were obtained, temperature, pressure and comparable input parameters for the simulation. Furthermore, the information mentioned can also contain information about a product or product produced in parallel to the simulated process in the real plant. include a corresponding product identifier. In this way, for example, an energy consumption value determined in the course of its vulcanization process can be assigned to a manufactured product.

Furthermore, the edge device 500 or the digital twin 502 in the edge device 500 can be designed and set up in such a way that the determined energy outflow, energy inflow and/or energy consumption values are transmitted back to the control device 130 via the fieldbus line 139 and are transmitted there as input data for a control program for controlling the tire heating press 100 and/or the heating system 102 for the tire heating press 100 . The control program can be designed and set up in such a way that a certain default range for energy consumption of the heating system 102 when heating up the heating bladder 114 is specified and the control of the heating system is designed and set up in such a way that the energy consumption of the tire heating press 100 is in this default range. By retransmitting one of the virtual sensors 580, 581, 582, 583, 584, 585, 586, 587, 588 within the simulation

504 obtained energy consumption value in the steam heating of the bladder 114, the heating system 102 can then be controlled so that the energy consumption is permanently in this default range.
