Description

[0001] Method for preventing a collision between relatively movable sections of a test bench of a test bench system, test bench system, computer program and computer-readable storage medium

[0002] The present invention relates to a method for preventing a collision between sections of a test bench of a test bench system that are movable relative to one another.

[0003] Test benches and test bench systems that, in addition to the test bench, also feature control computers for operating the test benches are known from the state of the art. For example, test benches that can move multiple axes of motion may have the problem that it is not obvious whether a specific setpoint specification for the axes will lead to a collision between two components of the system. In other words, it is desirable for test benches that, regardless of the complexity of the test bench structure and regardless of the different movement options of one or more sections of the test benches, a collision between sections of the test benches that can be moved relative to one another can be easily prevented.

[0004] It is therefore the object of the present invention to prevent a collision between sections of the test bench that can be moved relative to one another in a simple manner, regardless of the complexity of the structure of a test bench and regardless of the different movement possibilities of one or more sections of the test bench.

[0005] According to a first aspect of the invention, the stated object is achieved by a method having the features of patent claim 1. The method is provided for preventing a collision between sections of a test bench of a test bench system that are movable relative to one another. The method comprises the following steps: Providing a simulation model that represents the test bench and the sections of the test bench that are movable relative to one another. Determining a target value for a movement of a first section of the test bench. Moving a simulated first section, which represents the first section of the test bench, based on the determined target value. Determining a distance between the simulated first section and a simulated second section of the test bench, wherein the simulated second section represents a second section of the test bench. Comparing the determined distance with a predetermined minimum distance.Then, if the determined distance is equal to or greater than the specified minimum distance, move the first section of the test bench based on the determined target value.

[0006] As already described, the method is provided for preventing a collision between sections of the test bench of the test bench system that are movable relative to one another. In the context of the present invention, sections of the test bench that are movable relative to one another are preferably understood to mean that one section of the test bench is movable relative to a reference, such as a frame of the test bench, and another section of the test bench is fixed relative to the reference and is, for example, the frame itself. Thus, a first section of the test bench that is movable relative to the frame can be provided and a second section of the test bench that is fixed relative to the frame can be provided, wherein a collision between the first section and the second section is prevented by means of the method.In the context of the present invention, sections of the test stand that are movable relative to one another preferably also mean that two sections of the test stand are movable relative to a reference, such as the frame. Thus, a first section of the test stand that is movable relative to the frame can be provided, and a second section of the test stand that is also movable relative to the frame can be provided, wherein the method prevents a collision between the first section and the second section. Movable relative to one another therefore means that at least one section of the test stand is movable relative to another section of the test stand.Even if, in connection with the present invention, the prevention of a collision between two sections of the test bench is described at some points, the method according to the invention also applies to three or more sections of the test bench, wherein, based on at least analogous features, a collision between all of these sections can be avoided with the aid of the method according to the invention. For example, several target values ​​can be provided for several movements of several sections of the test bench, several movements of several simulated sections can be carried out based on these target values, several distances between the simulated sections and other simulated sections of the test bench can be determined, and several distances can be compared with several predetermined minimum distances.The corresponding movements of the corresponding sections of the test bench based on the corresponding target values ​​are then carried out when a corresponding determined distance is equal to or greater than a corresponding specified minimum distance. This method can therefore be applied to test benches of any complexity.

[0007] As already described, the simulation model is provided, which represents the test bench and the sections of the test bench that can be moved relative to one another. The simulation model can also be referred to as a physics model. The simulation model represents the test bench and the sections of the test bench that can be moved relative to one another, which can include a gripping unit, a first gripping element, a second gripping element, an arm unit, a first arm element, a second arm element, and a frame. The simulation model can also be referred to as a simulated test bench.Likewise, the gripping unit of the simulation model can be referred to as the simulated gripping unit, the first gripping element of the simulation model as the simulated first gripping element, the second gripping element of the simulation model as the simulated second gripping element, the arm unit of the simulation model as the simulated arm unit, the first arm element of the simulation model as the simulated first arm element, the second arm element of the simulation model as the simulated second arm element, and the frame of the simulation model as the simulated frame. Using the simulation model, specific movements of the test bench sections that can be moved relative to one another can be calculated, and the simulation model can then be used to determine whether a collision or near-collision occurs during the specific movements.If this is the case, a corresponding movement of one or more of the relatively movable sections of the test bench can be prevented. Thus, the simulation model can be used to prevent a collision between relatively movable sections of the real and non-simulated test bench.

[0008] As already described, the setpoint for the movement of the first section of the test bench is determined. The setpoint for the movement of the first section can, for example, also define a movement of other sections of the test bench. For example, if the first section is a first gripping element of the test bench and the setpoint defines a movement of the first gripping element from a first position to a second position, a movement of a first arm element of an arm unit and a movement of a second arm element of the arm unit can also be provided for the movement of the first gripping element from the first position to the second position. Each movement of a section of the test bench can be assigned a corresponding setpoint, whereby a corresponding setpoint on the test bench can also lead to movements of other sections of the test bench.Several target values ​​can together form part of a test scheme that is run through by the test bench to test a component.

[0009] As already described, the simulated first section, which represents the first section of the test bench, is moved based on the determined target value. Therefore, it is not the first section of the test bench that is moved initially, i.e. not the real first section of the test bench, but the simulated first section, i.e. the virtual first section. Thus, the movement of the simulated first section can be used to check whether the simulated first section is getting too close to another simulated section of the simulated test bench. As already described, the distance between the simulated first section and the simulated second section of the test bench is determined, with the simulated second section representing the second section of the test bench.First, the distance between the two simulated sections of the test bench is determined, without allowing any contact between the actual sections of the test bench due to movement based on the determined target value. As already described, the determined distance is compared with a specified minimum distance. Because the minimum distance is specified, a specific minimum distance can be specified for a particular test bench, which is adapted to the complexity of the test bench. For example, different minimum distances can be specified, which can vary depending on the design and complexity of the test bench.For example, a first minimum distance can be provided for a first test bench, which has a less complex structure, and a second minimum distance can be provided for a second test bench, which has a more complex structure, wherein the first minimum distance is less than the second minimum distance. The specified minimum distance is preferably greater than zero in order to reliably prevent a collision between the sections of the test bench that can move relative to one another. The minimum distance can also be set individually for each pair of sections. For example, the minimum distance between a first section and a second section can be 25 mm, and the minimum distance between the first section and a third section can be 30 mm.

[0010] Then, if the distance is equal to or greater than the specified minimum distance, move the first section of the test bench based on the determined target value. By moving the first section of the test bench based on the determined target value when the distance is equal to or greater than the specified minimum distance, it is ensured that there is no collision between the first section of the test bench and the second section of the test bench when the first section of the test bench is moved based on the determined target value. Regardless of the complexity of the test bench design and regardless of the different movement options of the first section of the test bench, a collision between the first section and the second section can be easily prevented.In particular, due to the use of the simulation model and the implementation of a simulated movement of a simulated section of the test bench before the real section is moved, sensors on the real test bench can be dispensed with, or at least the number and complexity of the sensors on the real test bench can be significantly reduced, which significantly simplifies collision avoidance. In particular, the present method can be used to prevent a collision between three or more sections of the test bench, wherein, based on at least similar features, a collision between all of these sections can be avoided using the method according to the invention.

[0011] In summary, it can be stated that regardless of the complexity of the structure of a test bench and regardless of the different movement possibilities of one or more sections of the test bench, a collision between sections of the test bench that are movable relative to one another can be easily prevented.

[0012] In one embodiment, if the distance is smaller than the specified minimum distance, movement of the first section of the test bench is prevented based on the determined target value. By preventing movement of the first section of the test bench based on the determined target value if the distance is smaller than the specified minimum distance, the simulation model can be used to prevent a collision or at least an excessive approach between the first section and the second section of the test bench.

[0013] In one embodiment, if the distance is smaller than the specified minimum distance, the determined target value is adjusted. Using the adjusted target value, a movement of the first section can then be carried out and a collision between the first section and the second section can be avoided.

[0014] In one embodiment, the simulated first section is moved based on the adjusted target value, a distance between the first simulated section and the simulated second section is determined, the distance being compared to the predetermined minimum distance, and then, if the distance is equal to or greater than the predetermined minimum distance, the first section of the test bench is moved based on the adjusted target value. By moving the first section of the test bench based on the adjusted target value when the distance is equal to or greater than the predetermined minimum distance, it is ensured that no collision occurs between the first section of the test bench and the second section of the test bench when the first section of the test bench is moved based on the adjusted target value.

[0015] In one embodiment, if the distance is smaller than the predefined minimum distance, movement of the first section of the test bench is prevented based on the adjusted target value. By preventing movement of the first section of the test bench based on the adjusted target value if the distance is smaller than the predefined minimum distance, the simulation model can be used to prevent a collision or at least an excessive approach between the first section and the second section of the test bench.

[0016] Even if the method steps are described in a specific order, the present invention is not limited to this order. Rather, the individual method steps can be carried out in any meaningful order, in particular at least partially in parallel to one another.

[0017] According to a second aspect of the invention, the stated object is achieved by a test bench system having the features of patent claim 6. The test bench system comprises the test bench with sections that can be moved relative to one another and means that are adapted to carry out the steps of the method according to the first aspect of the invention.

The features, technical effects and / or advantages described in connection with the method according to the first aspect of the invention also apply at least analogously to the test bench system according to the second aspect of the invention, so that a corresponding repetition is omitted here.

[0018] According to a third aspect of the invention, the stated object is achieved by a computer program having the features of patent claim 7. The computer program comprises instructions which, when executed by a computer, cause the computer to carry out the steps of the method according to the first aspect. The computer program can be stored on one data memory or on multiple data memories of the test bench system according to the second aspect. The data memory of the test bench system forms or the data memories of the test bench system form an example of a computer-readable storage medium. The instructions of the computer program can be executed by the processor of the test bench system or the processors of the test bench system.The features, technical effects and / or advantages described in connection with the method according to the first aspect of the invention and in connection with the test bench system according to the second aspect of the invention also apply at least analogously to the computer program according to the third aspect of the invention, so that a corresponding repetition is omitted at this point.

[0019] According to a fourth aspect of the invention, the stated object is achieved by a computer-readable storage medium having the features of patent claim 8. The computer-readable storage medium comprises instructions which, when executed by a computer, cause the computer to perform the steps of the method according to the first aspect.

[0020] Further features, advantages, and possible applications of the present invention will become apparent from the following description of the exemplary embodiments and the figures. All described and / or illustrated features, individually and in any combination, constitute the subject matter of the invention, regardless of their composition in the individual claims or their references. In the figures, the same reference numerals continue to represent the same or similar objects.

[0022] Figure 3 shows a schematic representation of an embodiment of a method according to the invention.

[0023] Figures 1 and 2 show schematic representations of an embodiment of a test bench system 1 according to the invention, and Figure 3 shows a schematic representation of an embodiment of a method according to the invention.

[0024] The test bench system 1 comprises a test bench 3 having a gripping unit 5 comprising a first gripping element 7 and a second gripping element 9. The first gripping element 7 and the second gripping element 9 can be moved relative to one another in order to hold an object between them in a holding configuration and to move this object from a first position to a second position by pivoting an arm unit 11. The arm unit 11 has a first arm element 13 and a second arm element 15. The first arm element 13 is pivotally attached to the frame 17 by a first end section. The second arm element 15 is pivotally attached to a second end section of the first arm element 13 by a first end section. Furthermore, the second arm element 15 is pivotally connected to the gripping unit 5 by a second end section.By pivoting the gripping unit 5 and / or pivoting the first arm element 13 and / or pivoting the second arm element 15, the gripping unit 5 and in particular an object held by the gripping unit 5 can be moved from one position to another position. Figures 1 and 2 also show a simulation model 19, which can also be referred to as a physics model. The simulation model 19 represents the test bench 3 and thus, in the illustrated embodiment, the gripping unit 5, the first gripping element 7, the second gripping element 9, the arm unit 11, the first arm element 13, the second arm element 15 and the frame 17. The simulation model 19 can also be referred to as a simulated test bench.Likewise, the gripping unit of the simulation model 19 can be referred to as a simulated gripping unit, the first gripping element of the simulation model 19 as a simulated first gripping element, the second gripping element of the simulation model 19 as a simulated second gripping element, the arm unit of the simulation model 19 as a simulated arm unit, the first arm element of the simulation model 19 as a simulated first arm element, the second arm element of the simulation model 19 as a simulated second arm element and the frame of the simulation model 19 as a simulated frame.

[0025] The method according to the invention shown in Figure 3 is intended to avoid a collision between sections of the test bench 3 that are movable relative to one another. In the context of the present invention, sections of the test bench 3 that are movable relative to one another are to be understood as meaning the situation in which only one section of the test bench 3 is movable relative to a reference, such as the frame 17, and another section of the test bench 3 is fixed relative to the reference and can, for example, be the frame 17 itself. In the context of the present invention, sections of the test bench 3 that are movable relative to one another are to be understood as meaning the situation in which two sections of the test bench 3 are movable relative to a reference, such as the frame 17.Movable relative to one another therefore means that at least one section of the test bench 3 is movable relative to another section of the test bench 3. In the following, the case is considered in which the first gripping element 7 is regarded as a first section of the test bench 3 and the frame 17 is regarded as a second section of the test bench 3. Each section of the test bench 3 can be represented by the simulation model 19, so that for each section of the test bench 3, a corresponding simulated section is provided in the simulation model 19. In the simulation model 19, a corresponding simulated first section is therefore provided for the first section of the test bench 3 and a corresponding simulated second section is provided for the second section of the test bench 3.

[0026] In the method according to the invention, in a first method step 101, the simulation model 19 is first provided, which represents the test bench 3 and the sections of the test bench 3 that can be moved relative to one another. In a second method step 102, a target value for a movement of the first section of the test bench 3, i.e. a target value for a movement of the first gripping element 7, is determined. In a third method step 103, the simulated first section, which represents the first section of the test bench 3, is moved based on the determined target value. The simulated first gripping element, which represents the first gripping element 7, is therefore moved based on the determined target value. In a fourth method step 104, a distance between the simulated first section and the simulated second section of the test bench 3 is determined, wherein the simulated second section represents the second section of the test bench 3.The distance between the simulated first gripping element, which represents the first gripping element 7, and the simulated frame, which represents the frame 17, is determined.

[0027] In a fifth method step 105, the distance is compared with a predetermined minimum distance. If the distance is equal to or greater than the predetermined minimum distance, the first section of the test stand 3 is moved based on the determined target value. The first gripping element 7 is therefore moved based on the determined target value if the distance is equal to or greater than the predetermined minimum distance. If the distance is less than the predetermined minimum distance, movement of the first section of the test stand 3 is prevented based on the determined target value. If the distance is less than the predetermined minimum distance, movement of the first gripping element 7 is prevented based on the determined target value.By virtue of the fact that the movement of the first section is only carried out based on the determined target value when the distance is equal to or greater than the predefined minimum distance and is then prevented when the distance is smaller than the predefined minimum distance, a collision between the first section and the second section of the test stand 3 can be prevented with the aid of the simulation model 19. In the illustrated embodiment of the test stand 3, a collision between the first gripping element 7 of the test stand 3 and the frame 17 of the test stand 3 can be prevented with the aid of the simulation model 19 by virtue of the fact that the movement of the first gripping element 7 is only carried out based on the determined target value when the distance is equal to or greater than the predefined minimum distance and is then prevented when the distance is smaller than the predefined minimum distance.

[0028] For example, if the distance is smaller than the specified minimum distance, the determined target value can be adjusted. Using the adjusted target value, a movement of the first section can then be carried out and a collision between the first section and the second section can be avoided. Before the first section is moved based on the adjusted target value, the first simulated section is first moved based on the adjusted target value, a distance is determined between the first simulated section and the second simulated section. The distance is compared with the specified minimum distance, and then, if the distance is equal to or greater than the specified minimum distance, the first section of test bench 3 is moved based on the adjusted target value.If the distance is smaller than the specified minimum distance, movement of the first section of test bench 3 is prevented based on the adjusted target value. Because the movement of the first section is only carried out based on the adjusted target value if the distance is equal to or greater than the specified minimum distance and is then prevented if the distance is smaller than the specified minimum distance, a collision between the first section and the second section of test bench 3 can be reliably prevented with the help of the simulation model 19, even after an adjustment of the target value.In the illustrated embodiment of the test bench 3, by virtue of the fact that the movement of the first gripping element 7 is only carried out based on the adjusted target value when the distance is equal to or greater than the specified minimum distance and is then prevented when the distance is smaller than the specified minimum distance, a collision between the first gripping element 7 of the test bench 3 and the frame 17 of the test bench 3 can be reliably prevented with the aid of the simulation model 19, even after an adjustment of the target value.

[0029] As already described, the test bench system 1 comprises the test bench 3. In addition, the test bench system 1 comprises a control computer 21 and a simulation computer 23. The control computer 21 and the simulation computer 23 each have a processor and a data memory. The components of the test bench system 1, in particular the processors and data memories, can also be referred to as means of the test bench system 1. The means are adapted to carry out the steps of the described method. A computer program is provided which comprises instructions which, when executed by the control computer 21 and the simulation computer 23, carry out the steps of the described method. For this purpose, the computer program has two sections, wherein a first section of the two sections is executed by the control computer 21 and a second section of the two sections is executed by the simulation computer 23.As an alternative to the control computer 21 and the simulation computer 23, only one computer can be provided that can execute the instructions of the computer program. Furthermore, a computer-readable storage medium is provided that includes instructions that, when executed by a computer, cause the computer or the control computer 21 and the simulation computer 23 to perform the steps of the described method.

[0030] As already described, the simulation model 19, which represents the test bench 3 and the sections of the test bench 3 that are movable relative to one another, is provided. The simulation model 19 is stored electronically in the data memory of the simulation computer 23. As also already described, the target value for a movement of the first section of the test bench 3, i.e., for a movement of the first gripping element 7, is determined. The target value is stored electronically in the data memory of the control computer 21 and is one of several target values ​​that together form part of a test scheme stored in the data memory of the control computer 21.To determine the target value, before a movement of the first gripping element 7 is carried out based on the target value, the target value is read out from the data memory of the control computer 21 using the processor of the control computer 21, and a target value signal representing the target value is sent from the control computer 21 to the simulation computer 23. With the help of the processor and data memory of the simulation computer 23, the simulated first gripping element is moved in the simulation model 19 based on the determined target value. When moving the simulated first gripping element based on the determined target value, the distance between the simulated first gripping element and the simulated frame is determined continuously or at regular intervals, for example at predetermined time intervals or after a predetermined movement distance has been covered.

[0031] For each determined distance, the simulation computer 23 compares the determined distance with the specified minimum distance. If each determined distance is equal to or greater than the specified minimum distance, a first distance signal representing the fact that each determined distance is equal to or greater than the specified minimum distance is sent from the simulation computer 23 to the control computer 21. If at least one determined distance is smaller than the specified minimum distance, a second distance signal representing the fact that at least one determined distance is smaller than the specified minimum distance is sent from the simulation computer 23 to the control computer 21.Depending on whether the control computer 21 receives the first distance signal or the second distance signal for the target value, if the control computer 21 receives the first distance signal, a control signal is sent from the control computer 21 to the test bench 3, which leads to a movement of the first gripping element 7 based on the determined target value, and if the control computer 21 receives the second distance signal, no corresponding control signal is sent from the control computer 21 to the test bench 3, so that a movement of the first gripping element 7 based on the determined target value is prevented or not carried out.

[0032] If at least one determined distance is smaller than the specified minimum distance, the simulation computer 23 adjusts the determined target value. Using the processor and data memory of the simulation computer 23, the simulated first gripping element is moved in the simulation model 19 based on the adjusted target value. When the simulated first gripping element is moved based on the adjusted target value, the distance between the simulated first gripping element and the simulated frame is determined continuously or at regular intervals, for example, at specified time intervals or after a specified distance has been traveled.

[0033] For each determined distance, the distance is compared with the specified minimum distance using the simulation computer 23. If each determined distance is equal to or greater than the specified minimum distance, a first distance signal representing the fact that each determined distance is equal to or greater than the specified minimum distance is sent from the simulation computer 23 to the control computer 21. If at least one determined distance is smaller than the specified minimum distance, a second distance signal representing the fact that at least one determined distance is smaller than the specified minimum distance is sent from the simulation computer 23 to the control computer 21.Depending on whether the control computer 21 receives the first distance signal or the second distance signal for the adjusted target value, if the control computer 21 receives the first distance signal, a control signal is sent from the control computer 21 to the test bench 3, which leads to a movement of the first gripping element 7 based on the adjusted target value, and if the control computer 21 receives the second distance signal, no corresponding control signal is sent from the control computer 21 to the test bench 3, so that a movement of the first gripping element 7 based on the adjusted target value is prevented or not carried out.

[0034] Figure 2 shows an arrangement of the test bench 3, wherein the first gripping element 7, in comparison to the arrangement of the test bench 3 in Figure 1, has been moved based on a first determined target value, because it was initially determined based on the simulation model 19 that after a movement of the simulated first gripping element, the distance between the simulated first gripping element and the simulated frame is equal to or greater than the specified minimum distance. Figure 2 shows that, with the help of the simulation model 19, the simulated first gripping element is moved based on a second determined target value and the distance between the simulated first gripping element and the simulated frame is smaller than the specified minimum distance (shown with a circle), so that a movement of the first gripping element 7 is prevented based on the second determined target value.
