Description

[Technical Field]

[0001] The present invention relates to a method for predicting a transferable amount of a high viscosity material, the transferable amount being transferable by an electrically drivable machine. The present invention further relates to a system for carrying out such a method. [Background technology]

[0002] Conventionally, machines having an internal combustion engine and a fuel tank are used to transport high-viscosity materials on construction sites. The internal combustion engine is supplied with fuel from the fuel tank. In this case, the amount of high-viscosity material that can still be transported by the machine depends on the fuel fill level of the fuel tank. If an electrically driven machine is used to transport high-viscosity materials instead of a machine with an internal combustion engine, the fuel tank is omitted, and therefore the possibility of displaying the fill level is also eliminated. Summary of the Invention [Problem to be solved by the invention]

[0003] The object of the present invention is to provide a method for predicting the amount of highly viscous material that can be transported by an electrically drivable machine, and a system equipped with such an electrically drivable machine, which allows a particularly reliable transport operation for transporting highly viscous materials. [Means for solving the problem]

[0004] The method according to the present invention is used to predict a transferable amount of a high-viscosity material. The transferable amount is transferable by an electrically drivable machine. Unless otherwise specified, the terms "drivable" and "driven" are used synonymously in this context. The method comprises the following step a): According to step a), a determination is made of the energy requirement required by the electrically drivable machine to transfer a predetermined unit amount of high-viscosity material. The method further comprises step b): According to step b), a determination is made of the energy stock available for driving the electrically drivable machine. The method further comprises step c): According to step c), a comparison is made of the energy requirement per predetermined unit amount and the energy stock to estimate the transferable amount of high-viscosity material. This estimation advantageously prevents the existing energy stock from being depleted during operation of the electrically drivable machine before the desired amount of high-viscosity material has been transferred. In the worst case scenario, if the desired amount of high-viscosity material cannot be completely transferred, residues of high-viscosity material may remain in the electrically drivable machine unless measures are taken. This residue can then harden, which can lead to damage or even complete failure of the electrically driven machine. This can be advantageously avoided by the method according to the invention. In this way, a particularly reliable conveying operation for conveying highly viscous materials is possible.

[0005] In one embodiment of the present invention, steps a), b), and / or c) are performed before the high-viscosity material is transported by the electrically drivable machine. In particular, steps a), b), and / or c) are performed using a parameterizable digital model of the electrically drivable machine. In this way, it can be ensured, even before the start of the transport operation, that the electrically drivable machine never finds itself in a situation where its energy stock is too low for the desired transport amount. Alternatively or additionally, steps a), b), and / or c) are performed while the high-viscosity material is being transported by the electrically drivable machine. In this case, steps a), b), and / or c) can be continuously and repeatedly performed during the transport of the high-viscosity material. In particular, steps a), b), and / or c) are performed during the transport of the high-viscosity material such that the amount of high-viscosity material that can still be transported, estimated by step c), is continuously updated. This makes it possible to intervene in the transport operation in time if the energy stock is about to be depleted early. This proves to be advantageous, in particular when energy requirements change. Energy requirements may vary as the geodetic head that must be overcome when transporting high viscosity materials and / or the consistency of the building material and / or the transport rate changes.

[0006] In another embodiment of the invention, the electrically drivable machine has an electric energy storage device. When determining the energy stock in step b), the amount of energy stored in the electric energy storage device is taken into account. The electric energy storage device can be charged with electric energy by drawing in charging power, and the charging power is taken into account when determining the energy stock in step b). In this way, the energy stock can be replenished during the transport of the highly viscous material. Thus, the limit range of the energy stock can be extended during the transport of the highly viscous material. This extension of the energy stock can advantageously be taken into account when estimating in step c).

[0007] In another embodiment of the invention, the electrically drivable machine has an electric drive for transporting a highly viscous material. To transport the highly viscous material, the electric drive is supplied with electric energy from an electric energy storage of the electrically drivable machine. The electrically drivable machine may have an electric connection for connecting its electric drive and, alternatively or additionally, its electric energy storage to an (external) power supply network. Advantageously, the electric drive can be supplied with electric energy while the electric energy storage is being charged.

[0008] In another embodiment of the invention, when carrying out step a), a quotient of energy requirement / unit amount is determined. The quotient of energy requirement and unit amount estimates the amount of energy required to transport a given unit amount of highly viscous material. This advantageously results in a single parameter that allows the estimation in step c), which can be particularly easily processed, in particular calculated, electronically.

[0009] In another embodiment of the present invention, the method further comprises step d), in which the electrically-driveable machine is operated based on the transportable amount of the high-viscosity material estimated in step c). In particular, the electrically-driveable machine can automatically switch between a plurality of operating modes in which the electrically-driveable machine consumes different amounts of electrical energy. This allows for automatic range optimization of the electrically-driveable machine.

[0010] In another embodiment of the invention, the electrically drivable machine has an electric energy storage device. In that case, when performing step a), the energy requirement for the predetermined unit amount is determined based on the current power delivered from the electric energy storage device. Alternatively or additionally, the energy requirement for the predetermined unit amount is determined based on past time variations in the power delivered from the electric energy storage device. This allows for particularly accurate prediction.

[0011] In another embodiment of the present invention, when performing step a), the past temporal fluctuations of the power delivered from the electrical energy storage are weighted more highly relative to the power currently delivered from the electrical energy storage the shorter the time since the high-viscosity material transport operation was resumed. In this way, power fluctuations that deviate from the average of the electrically driven machine, which are particularly frequent and noticeable when the electrically driven machine is started, can be advantageously compensated for.

[0012] In another embodiment of the invention, the current transmission power is drawn only through the electrical connection of the electrically driven machine as long as the transmission power does not exceed the maximum connection power. As long as the transmission power exceeds the maximum connection power, the current transmission power is drawn through the electrical connection with the maximum connection power and additionally from the electrical energy storage. In this way, it can be advantageously ensured that electrical energy is drawn from the electrical energy storage only when the connection power drawn from the power grid via the electrical connection is not sufficient to operate the electrically driven machine at a predetermined operating point. This predetermined operating point can be an operating point at which the electrically driven machine achieves its maximum efficiency.

[0013] In another embodiment of the invention, the electrical energy store is charged via the electrical connection as long as the transmitted power does not exceed the maximum connected power, in this way the maximum connected power can be fully utilized.

[0014] In another embodiment of the invention, based on the comparison according to step c) and the current state of charge of the electrical energy store, the remaining possible transfer amount of high-viscosity material is calculated and visualized, which advantageously makes it possible to intervene in the operation of the electrically drivable machine in time before the available energy stock is no longer sufficient to process the amount of high-viscosity material to be transferred.

[0015] In another embodiment of the invention, the percentage of the remaining possible transport volume of the high-viscosity material based on the power drawn via the electrical connection is calculated and visualized. Furthermore, the percentage of the remaining possible transport volume of the high-viscosity material based on the power drawn from the electrical energy store is calculated and visualized. The calculation and visualization can be based on the comparison according to step c), which also advantageously provides the operator with the possibility of intervention.

[0016] In another embodiment of the invention, the desired transfer amount can be specified, and it is then calculated whether the desired transfer amount can be transferred based on the comparison according to step c) and the current state of charge of the electrical energy store, which allows for a particularly reliable prediction.

[0017] In another embodiment of the present invention, the electrically drivable machine for transporting high-viscosity materials has a plurality of operating modes that differ in terms of the energy requirement per unit amount transported. In this case, one of the operating modes is selected based on the desired transport amount and the current state of charge of the electrical energy storage, especially when performing step c). This selection of one of the operating modes can be performed automatically, in particular. This ensures maximum utilization of the energy stock. The term "operating mode" can be understood as a synonym for the term "mode of operation."

[0018] In another embodiment of the present invention, the method further comprises step e). Step e) comprises outputting, in particular displaying, a range value based on the comparison in step c). In this case, the range value can represent the magnitude of the amount of energy stored in the electrical energy storage of the electrically drivable machine. Alternatively or additionally, the range value can represent the magnitude of the amount of high-viscosity material that can (still) be transported by the energy stock, in particular a multiple of the capacity of a standard mixer truck or other volume unit. Alternatively or additionally, the method further comprises step f). Step f) comprises setting, in particular inputting, a desired transport amount and outputting, in particular displaying, a feasibility attribute. The feasibility attribute is based on the comparison in step c) and the desired transport amount. In this case, the feasibility attribute can represent whether the desired transport amount can be covered by the transportable amount of high-viscosity material. Alternatively or additionally, the feasibility attribute may represent whether and / or by how much the desired transfer amount is greater than or less than the transferable amount of the high viscosity material, which allows for a particularly intuitive implementation of the method.

[0019] The present invention also relates to a system having an electrically drivable machine for conveying high-viscosity materials. The system further comprises an electronic computing unit, in particular a control device, connected to the electrically drivable machine, in particular for data transmission purposes. The electronic computing unit is then designed to carry out the method according to the present invention in accordance with the above description. The aforementioned advantages of the method according to the present invention therefore also apply to the system according to the present invention. In particular, the electrically drivable machine has an electric drive and an electric energy storage device for storing at least a portion of the energy stock for supplying the electric drive.

[0020] Other advantages and features of the present invention will become apparent from the claims and from the following description of preferred exemplary embodiments of the invention, illustrated by the drawings, in which the same reference signs refer to the same or similar or functionally identical parts.

[0021] It goes without saying that the features mentioned above and further described below can be used not only in the combinations respectively described, but also in other combinations or alone, without departing from the scope of the present invention. [Brief explanation of the drawings]

[0022] [Figure 1] 1 is a schematic flow chart illustrating the steps of one embodiment of the method according to the present invention. [Figure 2] 1 shows a schematic diagram of the structure of an embodiment of a system according to the invention; DETAILED DESCRIPTION OF THE INVENTION

[0023] The method according to the invention is used to predict a possible transportable amount of a highly viscous material D. The possible transportable amount of the highly viscous material D can be transported by an electrically drivable machine 1. The electrically drivable machine 1 is a functional component of a system 10 according to the invention. The electrically drivable machine 1 is used to transport the highly viscous material D. The system 1 comprises an electronic computing unit 11 connected to the electrically drivable machine 1, for example for data transmission purposes. The electronic computing unit 11 can be a control device. The electronic computing unit 11 is designed to carry out the method according to the invention. The electrically drivable machine 1 here comprises an electric drive 3 and an electric energy storage 2 for storing at least a part of an energy stock EV for supplying the electric drive 3. The electric drive 3 can be controlled by the electronic computing unit 11.

[0024] For example, the electrically drivable machine 1 further includes a high-viscosity material pump unit drivingly connected to the electric drive. The high-viscosity material pump unit may include transfer cylinders including variable-volume transfer chambers. To change the volumes of the transfer chambers, particularly in opposite directions, the transfer cylinders may each have a displaceable transfer piston. The high-viscosity material pump unit may further include an S-shaped pipe, one end of which is fluidly connected to a discharge pipe serving as a pump outlet. The S-shaped pipe may be disposed within a stock chamber for storing the high-viscosity material, which can be filled from above with the high-viscosity material. In this case, one end of the S-shaped pipe may be rotatably attached to the discharge pipe within the stock chamber. The variable-volume transfer chambers may open into the stock chamber. The S-shaped pipe may be swivellable relative to the transfer chambers within the stock chamber so as to be fluidly connected alternately to one of the transfer chambers. In this way, the interaction between the rotation of the S-shaped pipe and the volume change of the transfer chamber allows the high-viscosity material in the storage chamber to be alternately sucked into the transfer chamber and pumped out via the transfer chamber, through the S-shaped pipe, and out via the discharge pipe. An agitator can also be arranged in the storage chamber of the high-viscosity material pump unit. When transferring high-viscosity materials, the transfer pressure provided by the high-viscosity material pump unit can change, for example, if the transfer volume increases and / or the geodetic head is changed and / or the properties of the transferred high-viscosity material change. The change in transfer pressure also changes the transfer capacity provided by the high-viscosity material pump unit, and thus the energy requirement EB of the electrically driven machine 1.

[0025] The method according to the present invention includes step a), in which an energy requirement EB required by the electrically driven machine 1 to transport a predetermined unit amount of high-viscosity material D is determined. The method further includes step b), in which an energy stock EV available for driving the electrically driven machine 1 is determined. The method further includes step c), in which the energy requirement EB per predetermined unit amount is compared with the energy stock EV to estimate the amount of high-viscosity material D that can be transported. For example, steps a), b), and alternatively or additionally, c) are performed before the high-viscosity material D is transported by the electrically driven machine 1.

[0026] The execution of steps a), b), and / or c) prior to the transfer of the high-viscosity material D can be performed using a parameterizable digital model of the electrically drivable machine 1. The parameterizable digital model can be based on previously determined characteristic values ​​of the electrically drivable machine 1. The parameterizable digital model can be parameterized to adapt to the specific local conditions of the site of use, in particular a construction site. Instead of performing steps a), b), and / or c) before starting the transfer of the high-viscosity material, steps a), b), and / or c) can be performed during the transfer of the high-viscosity material. Thus, steps a), b), and alternatively or additionally, c) can be performed, for example, while the high-viscosity material D is being transferred by the electrically drivable machine 1. In that case, steps a), b), and / or c) can be continuously and repeatedly performed during the transfer of the high-viscosity material. In particular, steps a), b), and / or c) are performed during the transfer of the high-viscosity material such that the transferable amount of the high-viscosity material D estimated by step c) is continuously updated. In this way, information about the amount of highly viscous material D that can still be transported can be continuously updated.

[0027] As already mentioned, the electrically drivable machine 1 here has an electric energy storage device 2. In that case, the amount of energy ES stored in the electric energy storage device 2 is taken into account when determining the energy stock EV in step b). The electric energy storage device 2 can then be charged with electric energy by drawing in a charging power PL. This charging power PL can be taken into account when determining the energy stock EV in step b), i.e., how much electric energy is drawn from the electric energy storage device 2 and how much electric energy is supplied to the electric energy storage device 2 by the charging power PL can be taken into account.

[0028] As also mentioned above, the electrically drivable machine 1 here has an electric drive 3 for transporting the highly viscous material D. In this case, electrical energy is supplied to the electric drive 3 from an electric energy storage 2 of the electrically drivable machine 1 in order to transport the highly viscous material D. For example, the electrically drivable machine 1 has an electrical connection 4 for connecting the electric drive 3 to a power supply network V. Alternatively or additionally, the electrical connection 4 can be designed to connect the electric energy storage 2 to the power supply network V. The power supply network V can be an external, for example, public power supply network V. However, it is also conceivable that the power supply network V is a local power supply network V present in the area of ​​use. The electrical connection 4 can be designed to be connected to supply networks V of various current strengths.

[0029] For example, when carrying out step a), the quotient of energy requirement / unit amount is calculated, which estimates the amount of energy required to transport a given unit amount of high-viscosity material D.

[0030] In the embodiment of Fig. 1, the method further includes step d), which comprises operating the electrically drivable machine 1 based on the transferable amount of the high-viscosity material D estimated in step c).

[0031] For example, when step a) is performed, the energy requirement EB for a predetermined unit amount is determined, specifically, based on the current power PG delivered from the electrical energy storage device 2. Alternatively or additionally, the energy requirement EB is determined based on past temporal fluctuations in the power PG delivered from the electrical energy storage device 2. In this case, when step a) is performed, the past temporal fluctuations in the power PG delivered from the electrical energy storage device 2 may be weighted more heavily relative to the power PG currently delivered from the electrical energy storage device 2 the shorter the time since the high-viscosity material transport operation was resumed. In particular, at the start of the high-viscosity material transport operation, i.e., when the electrical machine 1 is restarted, the power PG delivered from the electrical energy storage device 2 may be significantly different from the average power PG delivered from the electrical energy storage device 2. This can be at least partially compensated for by the weighting. The electronic computing unit 11 may have a machine learning algorithm that can automatically learn from past operating data of the system 10 to gradually refine the accuracy of the predictions made by the method according to the present invention.

[0032] For example, the current transmission power PF is drawn only through the electrical connection 4 of the electrically driven machine 1, as long as the transmission power PF does not exceed the maximum connection power PA. In that case, as long as the transmission power PF exceeds the maximum connection power PA, the current transmission power PF is drawn through the electrical connection 4 having the maximum connection power PA and additionally from the electrical energy storage 2. That is, if the maximum connection power PA is not sufficient to provide the transmission power PF required for transporting a highly viscous material alone, a portion of the transmission power PF can additionally be drawn from the electrical energy storage 2. Conversely, if the maximum connection power PA is sufficient to provide the transmission power PF, energy withdrawal from the electrical energy storage 2 can be dispensed with. As long as the transmission power PF does not exceed the maximum connection power, the electrical energy storage 2 can be charged via the electrical connection 4.

[0033] For example, based on the comparison according to step c) and the current state of charge LZ of the electrical energy store 2, the remaining possible transfer amount of the high-viscosity material D is calculated. Furthermore, the remaining possible transfer amount of the high-viscosity material D can be visualized. For example, the percentage of the remaining possible transfer amount of the high-viscosity material D based on the power PB drawn via the electrical connection 4 and the percentage of the remaining possible transfer amount of the high-viscosity material D based on the power PG drawn from the electrical energy store 2 are calculated and visualized.

[0034] For example, a desired transfer amount can be specified. Based on the comparison according to step c) and the current state of charge LZ of the electrical energy store 2, it is calculated whether the desired transfer amount can be transferred. The result of this calculation can also be visualized.

[0035] The visualization described above makes it clear to the operator of the system 10 what would be involved if they were to utilize the power distributor connections present on the construction site. It is also possible to intentionally leave a certain amount of electrical energy remaining in the electrical energy store 2, so that this remaining amount can be used for further work on the construction site.

[0036] The electrically driven machine 1 for transporting the high-viscosity material D can have various operating modes. These operating modes differ, for example, in terms of the energy requirement per unit volume transported. In this case, one of the operating modes can be selected based on the desired transport volume and the current state of charge LZ of the electrical energy storage 2, particularly when performing step c). This selection of one of the operating modes can be automatic. This allows the electrically driven machine 1 to automatically switch to an energy-saving mode if, during normal operation of the electrically driven machine 1, it is determined that the energy stock EV is insufficient for the predetermined unit volume of the high-viscosity material D. In the energy-optimized operating mode, the piston speed of the high-viscosity material pump unit can be reduced. Furthermore, secondary consumers, such as the agitator and, if present, a cooler or filter, can be selectively deactivated. This adaptation can be performed in stages, so that, in addition to the energy-optimized operating mode, there are multiple operating modes that can gradually reduce the energy consumption of the electrically driven machine 1.

[0037] The method according to FIG. 1 further comprises step e). According to step e), a range value is output, e.g., displayed. The range value is based on the comparison according to step c). In this case, the range value may represent the magnitude of the amount of energy ES stored in the electric energy store 2 of the electrically drivable machine 1. Alternatively or additionally, the range value may represent the magnitude of the amount of high-viscosity material D that can still be transported by the energy stock EV. For example, the amount of high-viscosity material D that can still be transported can be expressed as a multiple of the capacity of a standard mixer truck or a multiple of another volume unit. The amount that can still be transported can be expressed in cubic meters per hour or cubic yards per hour. The "amount that can still be transported" can be called the "remaining transport amount."

[0038] According to FIG. 1 , the method further includes step f). According to step f), a desired transfer amount is set. For example, the desired transfer amount can be input. According to step f), a feasibility attribute based on the comparison according to step c) and the desired transfer amount is also output, in particular displayed. In this case, the feasibility attribute can represent whether the desired transfer amount is covered by the transferable amount of the high-viscosity material D. Alternatively or additionally, the feasibility attribute can represent whether the desired transfer amount exceeds or falls short of the transferable amount of the high-viscosity material D and / or by how much. The feasibility attribute can represent, for example, whether the energy stock EV is sufficient, barely sufficient, or insufficient to transfer the desired transfer amount.

[0039] A construction site planning system can be realized based on the parameterizable digital model of the electrically driven machine 1 mentioned at the beginning. This construction site planning system can be a computer program product that can be executed on a conventional computer. The computer program product can be used to simulate the number of electrically driven machines required to transport high-viscosity materials at a specific construction site. The simulated construction site can also exist as a parameterizable digital model of the construction site planning system. In this case, the parameterizable digital model(s) can be parameterized according to the specific site conditions of the simulated construction site and / or the electrically driven machine 1. For example, the specific site conditions can be the existing power supply network V and its specifications. The power supply network V can, for example, deliver current with a current strength of 16 A, 32 A, 63 A, or 125 A depending on the specifications. It is also possible that the simulated construction site does not have a power supply network V at all, in which case the electrically driven machine 1 can be supplied with electrical energy only from the electrical energy storage device 2.
