Description

background

[0001] The present disclosure relates to the control of fluid flows in a combustion device. In particular, the present disclosure relates to the control of fluid flows such as air and / or fuel gas using one or more actuators.

[0002] Changes in air temperature and / or air pressure cause fluctuations in the air ratio λ in a combustion device.

[0003] Combustion systems are therefore set to operate with excess air. This measure serves to prevent unhygienic combustion. The disadvantage of setting combustion systems to operate with excess air is a reduced system efficiency.

[0004] Due to the aforementioned fluctuations in the operation of a combustion device, at least one actuator of the combustion device must be readjusted during operation. The at least one actuator of the combustion device can be an air actuator or comprise an air actuator. The air actuator acts on an air supply through an air supply duct of the combustion device, wherein the air supply duct leads to a combustion chamber of the combustion device. In particular, the at least one actuator of the combustion device can be a blower for air or comprise such a blower. Furthermore, the at least one actuator of the combustion device can be an air damper or comprise such an air damper.

[0005] The at least one actuator of the combustion device can also be a fuel actuator or comprise a fuel actuator. The fuel actuator acts on a fuel supply through a fuel supply channel of the combustion device, wherein the fuel supply channel also leads to the combustion chamber of the combustion device. In particular, the at least one actuator of the combustion device can be a valve for fuel gas or comprise such a valve.

[0006] The readjustment of one or more such actuators can be performed based on a rate of change. The readjustment can, but does not have to, occur during operation. For example, a fan can increase or decrease its speed according to a maximum rate of change. The maximum rate of change is preferably a property of the fan. It can depend on the type and design of the fan. Fans that are controlled and / or regulated using pulse-width-modulated signals and / or converters are common.

[0007] Furthermore, an air damper can open or close according to a maximum change rate. The maximum change rate is preferably a property of the air damper. It can depend on the type and design of the air damper.

[0008] Furthermore, a fuel valve, such as a fuel gas valve or an oil valve, can open or close according to a maximum change rate. The maximum change rate is preferably a property of the fuel valve. It may depend on the type and design of the fuel valve.

[0009] In practice, the maximum rates of change of the actuators mentioned lead to a combustion device being conservatively adjusted to the actuator with the slowest rate of change. This means that the actuator with the slowest rate of change is used as the reference for all other actuators that are adjusted simultaneously and in conjunction with the first one. Likewise, the air damper with the slowest rate of change is used as the reference for all other air dampers. Furthermore, the fuel valve with the slowest rate of change is used as the reference for all other fuel valves.

[0010] This ensures that the combustion device can be operated with all or almost all fans, air dampers, or fuel valves. On the other hand, it also leads to delays. This means that the combustion device does not modulate as quickly as would be possible and / or appropriate. In the case of combustion with undesirable emissions, for example, it takes longer than necessary until the undesirable emissions are eliminated by changing at least one actuator. Furthermore, a change in the combustion device's output cannot be made as quickly as would be possible if the individual speeds were taken into account.

[0011] Furthermore, the actuators mentioned do not operate at their nominal speed. This can lead to deviations between the target and actual positions of the fans, air dampers, or fuel valves. In the worst case, such deviations lead to the shutdown of the combustion system.

[0012] The aim of the present disclosure is to improve the regulation and / or control of actuators in a combustion device. In particular, it concerns optimized changes in the rotational speeds and / or positions of such actuators. Summary

[0013] The present disclosure therefore teaches a combustion device comprising at least one actuator and a regulating and / or control and / or monitoring device. The at least one actuator acts on a supply of a fluid, such as air, fuel gas, or heating oil, through a supply channel of the combustion device. The supply channel opens into the burner of the same combustion device.

[0014] The regulating and / or control and / or monitoring device now sends a command to the at least one actuator. The command contains a change, for example a change in the speed of a fan or a change in the position of a valve. The at least one actuator receives the command and begins the change. It is helpful if the command is sent to the at least one actuator in such a way that the change occurs close to the nominal or maximum rate of change. This way, the change is implemented promptly in accordance with the command from the regulating and / or control and / or monitoring device. If the change is intended to eliminate unhygienic combustion, the unhygienic combustion ends promptly.

[0015] To determine the nominal or maximum rate of change of the at least one actuator, the control and / or monitoring device can query that rate from the at least one actuator. This means that the control and / or monitoring device sends a request signal to the at least one actuator. The at least one actuator ideally responds to the request signal by reporting a rate of change back to the control and / or monitoring device. The control and / or monitoring device is now able to implement a change in the supply of a fluid through the supply channel at the optimal rate of change.

[0016] Meanwhile, it may happen that no rate of change is stored or saved in the at least one actuator. In this case, the at least one actuator cannot report back a nominal or maximum rate of change of the at least one actuator. Instead, the response signal may contain an exception signal and / or an error signal, or a signal indicating an invalid value. Furthermore, the response may time out. In these cases, a rate of change is missing from the memory of the at least one actuator.

[0017] If no rate of change is stored or stored in the at least one actuator, the rate of change can be defined by parameterization or application of a constant value. For example, a rate of change can be parameterized in a control and / or monitoring device. For this purpose, the control and / or monitoring device can comprise a non-volatile memory. Furthermore, the control and / or monitoring device can assume a constant value. The constant value can be independent of the specific type of the at least one actuator.

[0018] For example, with external, speed-controlled fans, it may happen that no change rate is stored or saved in the at least one actuator. In this case, a manually initiated adaptation can be performed during commissioning. The step response of the at least one actuator, for example, the external, speed-controlled fan, is recorded. From this step response, possible change rates for acceleration and / or braking are determined.

[0019] The determination can be made, for example, by a control and / or monitoring device.

[0020] If, as a result of the request, no or no valid rate of change is available in the control and / or monitoring device, the rate of change can be determined empirically. For this purpose, the rotational speed and / or position of the at least one actuator are determined once before and once after a change and sent to the control and / or monitoring device. Furthermore, two timestamps are determined before and after the change, either in the at least one actuator or in the control and / or monitoring device.

[0021] A rate of change can then be empirically determined from the empirically determined mechanical variables and time stamps. The empirically determined rate of change can subsequently be used to automate at least one actuator instead of a requested rate of change. Short description of the characters

[0022] Various details will become apparent to those skilled in the art from the following detailed description. The individual embodiments are not limiting. The drawings accompanying the description can be described as follows: FIG 1 shows schematically a combustion device as a system. FIG 2 shows a sequence of a query of a rate of change of a rotational speed and / or a position of at least one actuator of the combustion device. FIG 3 shows a sequence of a measurement of the rate of change of the rotational speed and / or the position of at least one actuator of the combustion device. Detailed description

[0023] FIG 1 shows a combustion device comprising a burner 1, a heat consumer 2, a fan 3 with adjustable speed and a motor-adjustable flap 4. The motor-adjustable flap 4 is arranged after the air inlet 23. The heat consumer 2 (heat exchanger) can be, for example, a hot water boiler. The air supply 5 can be FIG 1 by the motor-adjustable flap 4 and / or by the speed setting of the fan 3 using the signal line 18. The air supply 5 can also be regulated. The signal line 18 can comprise or consist of a glass fiber. Signal lines made of glass fibers offer advantages in environments with explosive substances or mixtures.

[0024] If the flap 4 is missing, the air supply 5 can also be adjusted solely by the speed of the fan 3. Pulse width modulation, for example, can be used to adjust the speed of the fan 3. According to another embodiment, the motor of the fan 3 is connected to a converter. The speed of the fan 3 is thus adjusted via the frequency of the converter.

[0025] According to another embodiment, the fan 3 runs at a fixed, non-variable speed. The air supply 5 is then determined by the position of the flap 4. Furthermore, additional actuators are possible that change the air supply 5. These can be, for example, a nozzle adjustment of the burner and / or an adjustable flap in the exhaust duct.

[0026] The supply 6 (for example, particle flow and / or mass flow) of the fluid fuel through the fuel supply channel 25 can be adjusted by a fuel flap 9. According to one embodiment, the fuel flap 9 is a (motor-adjustable) valve.

[0027] Combustible gases such as natural gas and / or propane gas and / or hydrogen can be used as fuel. A liquid fuel such as heating oil can also be used as fuel. In this case, the flap 9 is replaced by a motor-adjustable oil pressure regulator in the return line of the oil nozzle. The safety shutdown function and / or closing function is implemented by the redundant safety valves 7, 8. According to a special embodiment, the safety valves 7, 8 and / or the fuel flap 9 are implemented as integrated unit(s).

[0028] Fuel is mixed with air in and / or upstream of burner 1. The mixture is burned in the combustion chamber of heat consumer 2. The heat is transported further within heat consumer 2. For example, heated water is pumped to heating elements and / or, in industrial furnaces, a material is heated (directly). Exhaust gas stream 10 is discharged (into the environment) via an exhaust gas path 26, for example, a chimney. Furthermore, exhaust gas stream 10 can be discharged (into the environment) via an exhaust gas path 26, for example, a chimney.

[0029] A control and / or monitoring device 16 automates at least one actuator of the combustion device. In one embodiment, the control and / or monitoring device 16 automates all actuators of the combustion device. Thus, the correct supply 6 of fuel and / or fuel gas is adjusted via the position of the flap 9 to the corresponding supply 5 of air for each power point. This results in the desired air ratio λ.

[0030] In one embodiment, the regulating and / or control and / or monitoring device 16 comprises a microcontroller. According to a specific embodiment, the regulating and / or control and / or monitoring device 16 is embodied as a microcontroller. In another embodiment, the regulating and / or control and / or monitoring device 16 comprises a microprocessor. According to another specific embodiment, the regulating and / or control and / or monitoring device 16 is embodied as a microprocessor.

[0031] The control and / or monitoring device 16 automates the blower 3 using the signal line 18 and / or the air damper 4 using the signal line 19. The signal line 19, like the signal line 18, can comprise or consist of a fiber optic cable. Fiber optic signal lines offer advantages in environments with explosive substances or mixtures.

[0032] To automate units 4, 5, values stored in the control and / or monitoring device 16 can be used. The values stored in the control and / or monitoring device 16 can, for example, be stored in the form of a characteristic curve and / or in the form of a mathematical relationship.

[0033] Preferably, the regulating and / or control and / or monitoring device 16 comprises a memory, for example a non-volatile memory. The values, in particular the characteristic curves and / or the mathematical relationships, are stored in the memory.

[0034] The position of fuel flap 9 is automated via signal line 22. During operation, the safety shutoff valves 7, 8 are opened via signal lines 20, 21. The safety shutoff valves 7, 8 are kept open during operation. Signal lines 20-22 can each comprise a single fiber optic cable or consist of a single fiber optic cable. Fiber optic signal lines offer advantages in environments with explosive substances or mixtures.

[0035] During operation, faults may occur in a flap 4, 9 and / or in the fan 3. Such faults may be detected, for example, in an electronic interface or control device of the flap 4 and / or the fan 3. Faults may be reported, for example, by a safety-related feedback signal regarding the position of the flap 4 via the (bidirectional) signal line 19 for the air flap 4. Faults may also be reported by a safety-related feedback signal regarding the position of the flap 9 via the (bidirectional) signal line 22 for the fuel flap 9.

[0036] A safety-related position signal can be implemented, for example, via redundant position sensors. If safety-related feedback regarding the speed is required, this can be provided via the (bidirectional) signal line 18 using (safety-related) speed sensors. For this purpose, redundant speed sensors can be used, for example, and / or the measured speed can be compared with the target speed. The control and feedback signals can be transmitted via different signal lines and / or via a bidirectional bus, such as a CAN bus.

[0037] NAMUR encoders and / or NAMUR sensors can also be used. These encoders and / or sensors are advantageously actuated via cams that are positively connected to the shaft of a drive of the at least one actuator 3, 4, 9. A speed can then be calculated from a pulse spacing of the signals recorded by the encoder and / or the sensor. Ideally, the speed can be calculated in a safety-relevant manner. This is achieved by arranging the cams at known angles around the drive shaft. For example, the cams can be arranged at angles of 60°, 120°, or 180° around the drive shaft. The direction of rotation can also be determined in a safety-relevant manner through asymmetric cam spacing and / or asymmetric angles between the individual cams.

[0038] In one embodiment, the speed calculation, in particular the safety-relevant speed calculation, is carried out by the regulating and / or control and / or monitoring device 16. The NAMUR sensors can be sensors according to DIN EN 60947-5-6 and / or VDE 0660-212:2000-12. The NAMUR sensors can be sensors according to DIN EN 60947-5-6 and / or VDE 0660-212:2000-12. The NAMUR sensors can be sensors according to DIN EN 60947-5-6 and / or VDE 0660-212:2000-12. The NAMUR sensors can be sensors according to DIN EN 60947-5-6 and / or VDE 0660-212:2000-12.

[0039] A side channel 24 is installed in front of burner 1. Side channel 24 is fluidly connected to air supply channel 11 at a point 12. A small amount of outflowing air 15 flows out through side channel 24. Together with burner 1 and exhaust path 26 of heat consumer 2, side channel 24 forms a flow divider. For a defined flow path through burner 1 and exhaust path 26, a corresponding value of air flow 15 flows out through side channel 24 for each value of air supply 5 (reversibly unique).

[0040] A flow resistance element 14 is mounted in the side channel 24. The flow rate 15 in the side channel 24 depends on the passage area of the flow resistance element 14.

[0041] With this arrangement, the flow rate (particle flow and / or mass flow) through the side channel 24 is a measure of the air supply 5 to the burner 1. Influences due to changes in the density of the air, for example, due to changes in the absolute pressure and / or the air temperature, are compensated by the mass flow sensor 13. To provide feedback of a signal from the mass flow sensor 13, this sensor 13 is connected to the regulating and / or control and / or monitoring device 16 via a signal line 17.

[0042] In known combustion devices, the speed of the fan 3 is changed conservatively at a slow rate of change. This ensures that the combustion device cooperates with a plurality of fans 3 of different designs and / or types. Furthermore, the position of the air damper 4 is changed conservatively at a slow rate of change. This ensures that the combustion device cooperates with a plurality of air dampers 4 of different designs and / or types. The rate of change of the air damper 4 is generally different from the rate of change of the fan 3.

[0043] Likewise, the position of the fuel actuator 9 is changed conservatively at a slow rate of change. This ensures that the combustion device cooperates with a plurality of fuel actuators 9 of different designs and / or different types. The rate of change of the fuel actuator 9 is generally different from the rate of change of the fan 3. The rate of change of the fuel actuator 9 is generally different from the rate of change of the air flap 4. In one embodiment, the fuel actuator 9 comprises a fuel flap. In a specific embodiment, the fuel actuator 9 is a fuel flap.

[0044] In one embodiment, the fan 3 comprises a microcontroller and / or a microprocessor. Furthermore, it is provided that the fan 3 comprises a memory, such as a non-volatile memory. The memory of the fan 3 is communicatively connected to the microcontroller and / or a microprocessor of the fan 3. In particular, the memory of the fan 3 can be part of the microcontroller.

[0045] In a further embodiment, the fan 3 is controlled by the regulating and / or control and / or monitoring device 16 using a pulse-width modulated signal. Furthermore, the fan 3 can be controlled via a bus signal. The bus signal can originate from a CAN bus. Furthermore, the speed can be recorded using one of the previously described NAMUR encoders and / or NAMUR sensors. The recorded speed is then converted by the regulating and / or control and / or monitoring device 16 into a measured speed value.

[0046] Preferably, the microcontroller and / or the microprocessor of the blower 3 is communicatively connected to the microcontroller and / or the microprocessor of the unit 16 via the signal line 18.

[0047] In one embodiment, the air damper 4 comprises a microcontroller and / or a microprocessor. Furthermore, the air damper 4 comprises a memory, such as a non-volatile memory. The memory of the air damper 4 is communicatively connected to the microcontroller and / or a microprocessor of the air damper 4. In particular, the memory of the air damper 4 can be part of the microcontroller.

[0048] Preferably, the microcontroller and / or the microprocessor of the air damper 4 is communicatively connected to the microcontroller and / or the microprocessor of the unit 16 via the signal line 19.

[0049] In one embodiment, the fuel actuator 9 comprises a microcontroller and / or a microprocessor. Furthermore, it is provided that the fuel actuator 9 comprises a memory, such as a non-volatile memory. The memory of the fuel actuator 9 is communicatively connected to the microcontroller and / or the microprocessor of the fuel actuator 9. In particular, the memory of the fuel actuator 9 can be part of the microcontroller of the fuel actuator 9.

[0050] Preferably, the microcontroller and / or the microprocessor of the fuel actuator 9 is communicatively connected to the microcontroller and / or the microprocessor of the unit 16 via the signal line 22.

[0051] The fuel actuator 9 can, for example, be a fuel flap. This means that the fuel flap comprises a microcontroller and / or a microprocessor. Furthermore, it is provided that the fuel flap comprises a memory, such as a non-volatile memory. The memory of the fuel flap is communicatively connected to the microcontroller and / or the microprocessor of the fuel flap. In particular, the memory of the fuel flap can be part of the microcontroller of the fuel flap.

[0052] Preferably, the microcontroller and / or the microprocessor of the fuel flap is communicatively connected to the microcontroller and / or the microprocessor of the unit 16 via the signal line 22.

[0053] To ensure that the speed and / or position of at least one actuator 3, 4, 9 does not change at the slowest speed to be expected, FIG 2 proceeded. Initially, in step 27, the regulating and / or control and / or monitoring device 16 requests a change rate from the at least one actuator 3, 4, 9. In particular, the microcontroller and / or microprocessor of the regulating and / or control and / or monitoring device 16 can request such a change rate. To this end, the microcontroller and / or microprocessor of the regulating and / or control and / or monitoring device 16 can generate a request signal and send it to the at least one actuator 3, 4, 9.

[0054] The at least one actuator 3, 4, 9 receives the request and / or the request signal in step 28. In step 29, the at least one actuator 3, 4, 9 responds to the request and / or the request signal. To do so, the microcontroller and / or the microprocessor of the at least one actuator 3, 4, 9 loads a change rate from the memory of the at least one actuator 3, 4, 9. In particular, the microcontroller and / or the microprocessor of the at least one actuator 3, 4, 9 can load a change rate from a non-volatile memory of the at least one actuator 3, 4, 9. The change rate can, for example, be a nominal and / or a maximum change rate of the at least one actuator 3, 4, 9.

[0055] In step 30, the at least one actuator 3, 4, 9 sends its rate of change back to the regulating and / or control and / or monitoring device 16. For this purpose, the microcontroller and / or microprocessor of the at least one actuator 3, 4, 9 can generate a first response signal from the loaded rate of change. After generating the first response signal, the microcontroller and / or microprocessor of the at least one actuator 3, 4, 9 sends the first response signal to the regulating and / or control and / or monitoring device 16.

[0056] In the subsequent step 31, the control and / or monitoring device 16 receives the first response signal. The control and / or monitoring device 16 determines the rate of change of the at least one actuator 3, 4, 9 from the first response signal.

[0057] Subsequently, in step 32, the control and / or monitoring device 16 generates a first automation signal. The first automation signal is generated taking into account the rate of change of the at least one actuator 3, 4, 9. In step 33, the first automation signal is sent to the at least one actuator 3, 4, 9. In step 34, the at least one actuator 3, 4, 9 receives the first automation signal.

[0058] The first automation signal may, for example, comprise a regulating signal and / or a control signal. The first automation signal may further be a regulating signal or a control signal.

[0059] Finally, in step 35, the at least one actuator 3, 4, 9 begins a change in its speed and / or position in response to receiving the first automation signal. The speed and / or position are changed in such a way that the reported rate of change of the at least one actuator 3, 4, 9 is not exceeded. This means that during the change in the speed and / or position of the at least one actuator 3, 4, 9, the rate of change remains less than or equal to the reported rate of change.

[0060] Ideally, the speed and / or position are changed such that the reported rate of change of the at least one actuator 3, 4, 9 is reached. In a further embodiment, the speed and / or position are changed such that a maximum of 95 percent of the rate of change of the at least one actuator 3, 4, 9 is reached.

[0061] Furthermore, the speed and / or position can be changed such that a maximum of 90 percent of the feedback change rate of the at least one actuator 3, 4, 9 is achieved. By not implementing its change at the maximum feedback change rate, the at least one actuator 3, 4, 9 is mechanically protected. At the same time, the change occurs sufficiently quickly.

[0062] In one embodiment, a reduction is already factored into the rate of change reported by the at least one actuator 3, 4, 9. This means that the reduced rate of change can be stored in a memory, for example, in a non-volatile memory, of the control and / or monitoring device 16. The purpose of this reduction is primarily to maintain a reserve. Thus, in the event of position or speed deviations of the at least one actuator 3, 4, 9, the deviations can be compensated for by independent changes. Ideally, this compensation does not require any intervention by the control and / or monitoring device 16.

[0063] Furthermore, the rotational speed and / or the position of the at least one actuator 3, 4, 9 is preferably changed such that the rate of change is reduced at the beginning of the change. Likewise, the rate of change can be reduced at the end of the change. The reason for the reduced rates of change is that, in particular, speed-controlled actuators 3 do not accurately follow the reported rate of change at the beginning and / or end.

[0064] It may now happen that one or more actuators 3, 4, 9 do not accurately follow the control commands of the control and / or monitoring device 16. Consequently, the control and / or monitoring device 16 registers a deviation between the actual position and the target position of the at least one actuator 3, 4, 9. Furthermore, the control and / or monitoring device 16 can register a deviation between the actual speed and the target speed of the at least one actuator 3, 4, 9. Such registrations of deviations can be carried out, for example, by evaluating one or more signals from a NAMUR encoder and / or NAMUR sensor.

[0065] In this case, the control and / or monitoring device 16 reduces the rate of change for all involved actuators 3, 4, 9. For example, the rates of change can be reduced by at least 30 percent, by at least 50 percent, or by at least 70 percent.

[0066] Advantageously, the control and / or monitoring device 16 registers the respective deviations for all participating actuators 3, 4, 9. The control and / or monitoring device 16 compares the deviations with each other and determines the largest deviation among the compared deviations. The control and / or monitoring device 16 reduces the change rates of all participating actuators 3, 4, 9 as a function of the largest deviation.

[0067] For example, the reduction in the rates of change of all participating actuators 3, 4, 5 can be a linear function of the largest deviation. The reduction in the rates of change of all participating actuators 3, 4, 5 can also be an affine function of the largest deviation.

[0068] In one embodiment with periodically reported speeds and / or positions, the regulating and / or control and / or monitoring device 16 can learn of the aforementioned deviations. This means that the regulating and / or control and / or monitoring device 16 learns that the at least one actuator 3, 4, 9 is not accurately following the reported rate of change. The change in speed and / or position can, for example, occur depending on the magnitude of a deviation between the target speed and the actual speed and / or between the target position and the actual position. In one embodiment, the change in speed and / or position is initiated by the regulating and / or control and / or monitoring device 16 depending on the magnitude of the deviation.In particular, a microcontroller and / or microprocessor of the regulating and / or control and / or monitoring device 16 can take into account the size of deviations between the target speed and the actual speed and / or between the target position and the actual position.

[0069] It is possible that in step 29, the at least one actuator 3, 4, 9 does not load a change rate from its memory. For example, it may be that no change rate is stored in the memory of the fan 3. The same applies to the air flap 4 or the fuel actuator 9. In particular, it may be that no change rate is stored in the memory of the fuel flap 9.

[0070] In this case, the at least one actuator 3, 4, 9 generates a second response signal in step 36. This second response signal indicates that no rate of change is reported. In particular, the second response signal can an error message and / or an exception message and / or an invalid value for the rate of change such as zero or a negative value Furthermore, the second response signal may include an error message and / or an exception message and / or an invalid value for the rate of change, such as zero or a negative value. Furthermore, the second response signal may include an error message and / or an exception message and / or an invalid value for the rate of change, such as zero or a negative value.

[0071] In particular, the microcontroller and / or microprocessor of the at least one actuator 3, 4, 9 can generate the second response signal. After generating the second response signal, the microcontroller and / or microprocessor of the at least one actuator 3, 4, 9 sends the second response signal to the control and / or monitoring device 16.

[0072] In the subsequent step 37, the control and / or monitoring device 16 receives the second response signal. The control and / or monitoring device 16 determines from the second response signal that a rate of change of the at least one actuator 3, 4, 9 has not been reported back. This means that the control and / or monitoring device 16 must determine the rate of change of the at least one actuator 3, 4, 9 by another means.

[0073] It is also possible that the regulating and / or control and / or monitoring device 16 does not receive a first or second feedback signal in either step 31 or step 37. The regulating and / or control and / or monitoring device 16 typically waits for a first or second feedback signal for a predetermined period of time. The predetermined period of time can, for example, be at least one hundred milliseconds, at least two hundred milliseconds, or at least five hundred milliseconds. Long predetermined times ensure that the regulating and / or control and / or monitoring device 16 does not miss any feedback signal.

[0074] If the specified time period elapses without a first or second feedback signal, the regulating and / or control and / or monitoring device 16 will have to determine the rate of change of the at least one actuator 3, 4, 9 by another means.

[0075] The determination of the rate of change of at least one actuator 3, 4, 9 by other means can be carried out as in FIG 3 The determination of the rate of change according to FIG 3 However, it can also be done independently of a previous query of a rate of change.

[0076] This means that the regulating and / or control and / or monitoring device 16 generates a first status query signal in an optional step 38. The first status query signal can, for example, indicate a first query of a first rotational speed and / or a first position of the at least one actuator 3, 4, 9.

For example, the initial and second status query signals can query a speed of the fan 3, a position of the air damper 4, or a position of the at least one fuel actuator 9.

[0096] The second status query signal is sent to the at least one actuator 3, 4, 9 in step 48. The second status query signal can, for example, be sent to the at least one actuator 3, 4, 9 after a predetermined delay of at least one second, at least two seconds, or at least five seconds. Long delay times enable precise determination of the rate of change of the at least one actuator 3, 4, 9.

[0097] Preferably, the predetermined delay begins upon transmission of the first and / or initial status query signal by the regulating and / or control and / or monitoring device 16. Likewise, the predetermined delay may begin upon transmission of the change signal by the regulating and / or control and / or monitoring device 16.

In a further embodiment, the at least one actuator 3, 4, 9 periodically generates status signals, so that the aforementioned queries are unnecessary. This means that in this case the second status signal is generated as part of a periodic generation of status signals. In particular, the microcontroller and / or microprocessor of the at least one actuator 3, 4, 9 can periodically generate status signals. In this case, the second status signal is generated as part of a periodic generation of status signals by the microcontroller and / or microprocessor of the at least one actuator 3, 4, 9.

[0101] Ideally, the second status signal additionally includes a second timestamp. The second timestamp indicates the time at which the second status signal is generated. The second timestamp can be determined, for example, by an internal clock of the microcontroller and / or the microprocessor of the at least one actuator 3, 4, 9.

The second timestamp can also be determined by counting clock cycles of the microcontroller and / or the microprocessor of the at least one actuator 3, 4, 9.

[0102] Alternatively, the control and / or monitoring device 16 can generate the second time stamp upon receipt of the second status signal in step 52 described below. The second time stamp can be determined, for example, by an internal clock of the microcontroller and / or the microprocessor of the control and / or monitoring device 16.

[0103] In step 51, the at least one actuator 3, 4, 9 sends the second status signal to the control and / or monitoring device 16.

[0104] In step 52, the regulating and / or control and / or monitoring device 16 receives the second status signal. The regulating and / or control and / or monitoring device 16 is now able to determine the rate of change of the rotational speed and / or position of the at least one actuator 3, 4, 9. For this purpose, a first mechanical status s 1 , i.e., a first rotational speed or a first position, is determined from the first status signal. Furthermore, a first time t 1 is determined from the first timestamp.

[0105] From the second status signal, a second mechanical status s 2 , i.e., a second speed or a second position, is determined. Furthermore, a second time t 2 is determined from the second timestamp. The rate of change v can be determined in this case: v = s 1 − s 2 t 1 − t 2

[0106] Preferably, the microcontroller and / or microprocessor of the control and / or monitoring device 16 determines the rate of change. Ideally, the microcontroller and / or microprocessor also determines the first and second mechanical status s 1 , s 2 as well as the first and second time stamps t 1 , t 2 .

[0107] In a related embodiment, an initial mechanical status si , i.e., an initial speed or an initial position, is determined from the initial status signal. Furthermore, an initial time ti is determined from the initial time stamp. A second mechanical status s 2 , i.e., a second speed or a second position, is determined from the second status signal. Furthermore, a second time t 2 is determined from the second time stamp. The rate of change v can be determined in this case: v = s i − s 2 t i − t 2

[0108] Preferably, the microcontroller and / or microprocessor of the control and / or monitoring device 16 determines the rate of change. Ideally, the microcontroller and / or microprocessor also determines the initial and second status si , s 2 as well as the initial and second time stamp ti , t 2 .

[0109] Subsequently, the control and / or monitoring device 16 can use the empirically determined rate of change in the automation of the at least one actuator 3, 4, 9. This means that the control and / or monitoring device 16 generates a second automation signal in step 53. The second automation signal is sent to the at least one actuator 3, 4, 9. The at least one actuator 3, 4, 9 receives the second automation signal in step 54. In response to receiving the second automation signal, the at least one actuator 3, 4, 9 changes its speed and / or position in step 55.

[0110] The second automation signal may, for example, comprise a regulating signal and / or a control signal. The second automation signal may further be a regulating signal or a control signal.

[0111] Preferably, the second automation signal is generated by the microcontroller and / or microprocessor of the regulating and / or control and / or monitoring device 16. In one embodiment, the first automation signal is different from the second automation signal. This means that the first and second automation signals contain different information.

[0112] Ideally, the speed and / or the position are changed such that the empirically determined rate of change v of the at least one actuator 3, 4, 9 is reached. In a further embodiment, the speed and / or the position are changed such that a maximum of 95 percent of the rate of change of the at least one actuator 3, 4, 9 is reached. Furthermore, the speed and / or the position can be changed such that a maximum of 90 percent of the determined rate of change of the at least one actuator 3, 4, 9 is reached. By the at least one actuator 3, 4, 9 not carrying out its change at the maximum empirically determined rate of change, the at least one actuator 3, 4, 9 is mechanically protected. At the same time, the change takes place sufficiently quickly.

[0113] Furthermore, the rotational speed and / or the position of the at least one actuator 3, 4, 9 is preferably changed such that the rate of change is reduced at the beginning of the change. Likewise, the rate of change can be reduced at the end of the change. The reason for the reduced rates of change is that, in particular, speed-controlled actuators 3 do not accurately follow the empirically determined rate of change at the beginning and / or end.

[0114] In one embodiment with periodically reported speeds and / or positions, the regulating and / or control and / or monitoring device 16 can learn of the aforementioned deviations. This means that the regulating and / or control and / or monitoring device 16 learns that the at least one actuator 3, 4, 9 is not accurately following the empirically determined rate of change. The change in speed and / or position can, for example, occur depending on the size of a deviation between the target speed and the actual speed and / or between the target position and the actual position. In one embodiment, the change in speed and / or position is initiated by the regulating and / or control and / or monitoring device 16 depending on the size of the deviation.In particular, a microcontroller and / or microprocessor of the regulating and / or control and / or monitoring device 16 can take into account the size of deviations between the target speed and the actual speed and / or between the target position and the actual position.
