Abstract
Description
Technical Field
[0001] The present invention relates to a method for preventing collisions between sections of a test bench that are movable relative to each other in a test bench system. Background Technology
[0002] In addition to the test bench, test benches and test bench systems with control computers for operating the test bench are known from the prior art. As an example, test benches capable of traveling along multiple movement axes may sometimes present the following problem: it is unclear whether selecting specific settings for each axis will lead to conflicts between the two modules during installation. In other words, it is desirable that, regardless of the complexity of the test bench design and the different movement options for one or more sections of the test bench, collisions between sections of the test bench that can move relative to each other be easily prevented.
[0003] Therefore, the object of the present invention is to easily prevent collisions between sections of the test bench that are capable of moving relative to each other, regardless of the complexity of the test bench design or the different movement options of one or more sections of the test bench. Summary of the Invention
[0004] According to a first aspect of the invention, the objective is achieved by a method having the features of claim 1. The method aims to prevent collisions between segments of a test bench system that are movable relative to each other. The method includes the steps of: providing a simulation model representing the test bench and its movable segments relative to each other; determining a setpoint value for the movement of a first segment of the test bench; moving a simulated first segment representing the first segment of the test bench based on the determined setpoint value; determining a distance between the simulated first segment and a simulated second segment of the test bench, the simulated second segment representing a second segment of the test bench; comparing the determined distance with a specified minimum distance; and moving the first segment of the test bench based on the determined setpoint value when the determined distance is equal to or greater than the specified minimum distance.
[0005] As already outlined, the method aims to prevent collisions between movable sections of a test bench system. In the context of this invention, movable sections of the test bench should preferably be understood to mean that one section of the test bench is movable relative to a reference object (e.g., the frame of the test bench), and another section of the test bench is fixed relative to the reference object, and the other section is, for example, the frame itself. Therefore, a first section of the test bench movable relative to the frame and a second section of the test bench fixed relative to the frame can be provided, and the method is used to prevent collisions between the first section and the second section. In the context of this invention, movable sections of the test bench should also preferably be understood to mean that both sections of the test bench are movable relative to the reference object (e.g., the frame). Therefore, a first section of the test bench movable relative to the frame and a second section of the test bench also movable relative to the frame can be provided, and the method is used to prevent collisions between the first section and the second section. Therefore, being movable relative to each other means that at least one section of the test bench is movable relative to another section of the test bench. Even though some paragraphs in the context of this invention describe preventing collisions between two sections of a test bench, the method according to the invention is also applicable to three or more sections of the test bench, wherein at least similar features can be used to avoid collisions between all such sections by means of the method according to the invention. Thus, as an example, for multiple setpoint values for multiple movements of multiple sections of the test bench, multiple movements can be performed by multiple simulated sections based on these setpoint values, multiple distances between the simulated sections and other simulated sections of the test bench can be determined, and these multiple distances can be compared with multiple specified minimum distances. When an applicable determined distance is equal to or greater than an applicable specified minimum distance, an applicable movement of the applicable section of the test bench is performed based on the applicable setpoint value. Therefore, the method can be applied to test benches of any complexity.
[0006] As already outlined, a simulation model is provided representing the test bench and its movable segments relative to each other. This simulation model may also be referred to as a physical model. The simulation model represents the test bench and its movable segments relative to each other, which may include clamping units, a first clamping element, a second clamping element, arm units, a first arm element, a second arm element, and a frame. This simulation model may also be referred to as a simulated test bench. Similarly, the clamping units of the simulation model may be referred to as simulated clamping units, the first clamping element of the simulation model may be referred to as simulated first clamping elements, the second clamping element of the simulation model may be referred to as simulated second clamping elements, the arm units of the simulation model may be referred to as simulated arm units, the first arm element of the simulation model may be referred to as simulated first arm elements, the second arm element of the simulation model may be referred to as simulated second arm elements, and the frame of the simulation model may be referred to as simulated frame. The simulation model can be used to calculate a specific movement of the movable segments of the test bench relative to each other, and then the simulation model can be used to determine whether the specific movement results in a collision or nearly results in a collision. In this case, applicable movement of one or more sections of the test bench that are capable of moving relative to each other can be prevented. Therefore, the simulation model can be used to prevent collisions between sections of a real test bench and a non-simulated test bench that are capable of moving relative to each other.
[0007] As already outlined, a setpoint value is determined for the movement of the first segment of the test bench. As an example, the setpoint value for the movement of the first segment may also define the movement of other segments of the test bench. For instance, when the first segment is a first clamping element of the test bench and the setpoint value defines the movement of the first clamping element from a first position to a second position, movement of a first arm element and movement of a second arm element of the arm unit may also be provided for the movement of the first clamping element from the first position to the second position. Each movement of a segment of the test bench may have an assigned applicable setpoint value on the test bench, which may also result in movement of other segments of the test bench. Multiple setpoint values may together form part of a test scheme in which the test bench tests the device.
[0008] As already outlined, the simulated first segment representing the first section of the test bench is moved based on a determined setpoint value. Therefore, it is not the actual first section of the test bench that moves first, but rather the simulated first segment, i.e., the virtual first portion, that moves first. Thus, the movement of the simulated first segment can be used first to check if it is too close to another simulated segment of the test bench. Also as already outlined, the distance between the simulated first segment and the simulated second segment representing the second section of the test bench is determined. Therefore, the distance between the two simulated segments of the test bench is determined first, without the possibility of contact occurring between the actual segments of the test bench due to movement based on the determined setpoint value.
[0009] As already outlined, the determined distance is compared to a specified minimum distance. Because this minimum distance is specified, a specific minimum distance can be provided for a particular test bench, tailored to the complexity of the test bench. For example, different minimum distances can be provided, varying depending on the design and complexity of the test bench. For instance, a first minimum distance can be provided for a less complex first test bench, and a second minimum distance can be provided for a more complex second test bench, where the first minimum distance is shorter than the second minimum distance. Preferably, the specified minimum distance is greater than zero to reliably prevent collisions between sections of the test bench that can move relative to each other. The minimum distance can also be set individually for each pair of sections. For example, the minimum distance between the first section and the second section could therefore be 25 mm, and the minimum distance between the first section and the third section could be 30 mm.
[0010] When the distance is equal to or greater than the specified minimum distance, the first segment of the test bench is moved based on a determined setpoint value. Moving the first segment of the test bench based on the determined setpoint value when the distance is equal to or greater than the specified minimum distance ensures that there is no collision between the first segment and the second segment of the test bench when the first segment is moved based on the determined setpoint value. Regardless of the complexity of the test bench design and regardless of the different movement options for the first segment, collisions between the first and second segments can be easily prevented. Specifically, the use of the simulation model before moving the real segment and the performance of the simulated movement of the simulated segments of the test bench allow for the elimination of sensors on the real test bench, or at least a significant reduction in the number and complexity of sensors on the real test bench, which greatly simplifies collision avoidance. Specifically, this method can be used to prevent collisions between three or more segments of the test bench, wherein at least similar features can be used to avoid collisions between all such segments by means of the method according to the invention.
[0011] In summary, it can be said that regardless of the complexity of the test bench design and the different movement options of one or more sections of the test bench, collisions between sections of the test bench that are capable of moving relative to each other can be easily prevented.
[0012] In one embodiment, when the distance is less than the specified minimum distance, movement of the first segment of the test bench is prevented based on a determined setpoint value. Since movement of the first segment of the test bench is prevented based on a determined setpoint value when the distance is less than the specified minimum distance, the simulation model can be used to prevent the first and second segments of the test bench from colliding or at least becoming too close.
[0013] In one embodiment, when the distance is less than the specified minimum distance, the determined setpoint value is adjusted. The adjusted setpoint value can then be used to perform movement of the first segment and avoid collisions between the first segment and the second segment.
[0014] In one embodiment, the simulated first segment is moved based on the adjusted setpoint value, and the distance between the first simulated segment and the simulated second segment is determined. This distance is compared to a specified minimum distance, and when the distance is equal to or greater than the specified minimum distance, the first segment of the test bench is moved based on the adjusted setpoint value. Moving the first segment of the test bench based on the adjusted setpoint value when the distance is equal to or greater than the specified minimum distance ensures that there is no collision between the first segment and the second segment of the test bench when the first segment is moved based on the adjusted setpoint value.
[0015] In one embodiment, when the distance is less than the specified minimum distance, movement of the first segment of the test bench is prevented based on an adjusted setpoint value. Since movement of the first segment of the test bench is prevented based on the adjusted setpoint value when the distance is less than the specified minimum distance, the simulation model can be used to prevent the first and second segments of the test bench from colliding or at least becoming too close.
[0016] Although the method steps are described in a specific order, the invention is not limited to that order. Rather, the individual method steps can be performed in any useful order, and in particular, at least in some cases, simultaneously with each other.

[0024] The test bench system 1 has a test bench 3, which has a clamping unit 5. The clamping unit 5 has a first clamping element 7 and a second clamping element 9. The first clamping element 7 and the second clamping element 9 are movable relative to each other to maintain an object between them in a holding configuration and to move the object from a first position to a second position via a pivoting arm unit 11. The arm unit 11 has a first arm element 13 and a second arm element 15. A first end portion of the first arm element 13 is pivotally mounted on a frame 17. A first end portion of the second arm element 15 is pivotally mounted on a second end portion of the first arm element 13. Additionally, the second end portion of the second arm element 15 is pivotally connected to the clamping unit 5. By pivoting the clamping unit 5 and / or pivoting the first arm element 13 and / or pivoting the second arm element 15, the clamping unit 5, and in particular the object held by the clamping unit 5, can move from one position to another.
[0025] Figure 1 and Figure 2 A simulation model 19, which may also be referred to as a physical model, is also shown. Simulation model 19 represents test bench 3, and therefore, in the exemplary embodiment shown, represents clamping unit 5, first clamping element 7, second clamping element 9, arm unit 11, first arm element 13, second arm element 15, and frame 17. Simulation model 19 may also be referred to as a simulation test bench. Similarly, the clamping unit of simulation model 19 may be referred to as a simulation clamping unit, the first clamping element of simulation model 19 may be referred to as a simulation first clamping element, the second clamping element of simulation model 19 may be referred to as a simulation second clamping element, the arm unit of simulation model 19 may be referred to as a simulation arm unit, the first arm element of simulation model 19 may be referred to as a simulation first arm element, the second arm element of simulation model 19 may be referred to as a simulation second arm element, and the frame of simulation model 19 may be referred to as a simulation frame.
[0026] Figure 3The method shown according to the invention aims to avoid collisions between sections of the test bench 3 that are movable relative to each other. In the context of the invention, sections of the test bench 3 that are movable relative to each other should be understood to mean that this covers cases where only one section of the test bench 3 is movable relative to a reference (e.g., frame 17), and where another section of the test bench 3 is fixed relative to the reference and, for example, that other section itself may be the frame 17. In the context of the invention, sections of the test bench 3 that are movable relative to each other should also be understood to mean that this also covers cases where both sections of the test bench 3 are movable relative to a reference (e.g., frame 17). Therefore, being movable relative to each other means that at least one section of the test bench 3 is movable relative to another section of the test bench 3. The following description considers the case where the first clamping element 7 is considered a first section of the test bench 3 and the frame 17 is considered a second section of the test bench 3. Each section of the test bench 3 can be represented by a simulation model 19, such that for each section of the test bench 3, a corresponding simulated section is provided in the simulation model 19. Therefore, simulation model 19 provides a corresponding simulated first section for the first section of test bench 3, and provides a corresponding simulated second section for the second section of test bench 3.
[0027] In the method according to the invention, the first method step 101 first involves providing a simulation model 19, which represents the test bench 3 and segments of the test bench 3 that are movable relative to each other. In the second method step 102, a setpoint value for the movement of the first segment of the test bench 3 is determined, i.e., a setpoint value for the movement of the first clamping element 7. In the third method step 103, a simulated first segment representing the first segment of the test bench 3 is moved based on the determined setpoint value. Therefore, a simulated first clamping element representing the first clamping element 7 is moved based on the determined setpoint value. In the fourth method step 104, the distance between the simulated first segment and a simulated second segment representing a second segment of the test bench 3 is determined. Therefore, the distance between the simulated first clamping element representing the first clamping element 7 and the simulated frame representing the frame 17 is determined.
[0028] In step 105 of the fifth method, the distance is compared with a specified minimum distance. When the distance is equal to or greater than the specified minimum distance, the first segment of the test bench 3 is moved based on a determined setpoint value. Therefore, when the distance is equal to or greater than the specified minimum distance, the first clamping element 7 is moved based on the determined setpoint value. When the distance is less than the specified minimum distance, movement of the first segment of the test bench 3 is prevented based on the determined setpoint value. Therefore, when the distance is less than the specified minimum distance, movement of the first clamping element 7 is prevented based on the determined setpoint value. Since movement of the first segment based on the determined setpoint value is only performed when the distance is equal to or greater than the specified minimum distance, and is prevented when the distance is less than the specified minimum distance, the simulation model 19 can be used to prevent collision between the first segment and the second segment of the test bench 3. In the exemplary embodiment shown for the test bench 3, since the movement of the first clamping element 7 based on the determined set point value is performed only when the distance is equal to or greater than the specified minimum distance, and is prevented when the distance is less than the specified minimum distance, it is possible to use the simulation model 19 to prevent the first clamping element 7 of the test bench 3 from colliding with the frame 17 of the test bench 3.
[0029] For example, when the distance is less than the specified minimum distance, the determined setpoint value can be adjusted. The adjusted setpoint value can then be used to move the first segment and prevent collisions between the first and second segments. Before moving the first segment based on the adjusted setpoint value, the first simulated segment is first moved based on the adjusted setpoint value, and the distance between the first and second simulated segments is determined. This distance is compared to the specified minimum distance, and when the distance is equal to or greater than the specified minimum distance, the first segment of the test bench 3 is moved based on the adjusted setpoint value. When the distance is less than the specified minimum distance, movement of the first segment of the test bench 3 is prevented based on the adjusted setpoint value. Since movement of the first segment based on the adjusted setpoint value is only performed when the distance is equal to or greater than the specified minimum distance, and is prevented when the distance is less than the specified minimum distance, even after the adjusted setpoint value, the simulation model 19 can reliably prevent collisions between the first and second segments of the test bench 3. In the exemplary embodiment shown in the test bench 3, since the movement of the first clamping element 7 based on the adjusted setpoint value is performed only when the distance is equal to or greater than the specified minimum distance and is prevented when the distance is less than the specified minimum distance, it is possible to reliably prevent the first clamping element 7 of the test bench 3 from colliding with the frame 17 of the test bench 3 even after the setpoint value has been adjusted.
[0030] As already outlined, the test bench system 1 includes a test bench 3. Furthermore, the test bench system 1 includes a control computer 21 and a simulation computer 23. The control computer 21 and the simulation computer 23 each have a processor and data memory. The components of the test bench system 1, particularly the processor and data memory, may also be referred to as the apparatus of the test bench system 1. This apparatus is configured to execute the steps of the outlined method. A computer program comprising commands is provided, which, when executed by the control computer 21 and the simulation computer 23, executes the steps of the outlined method. For this purpose, the computer program has two sections, a first section of which is executed by the control computer 21, and a second section of which is executed by the simulation computer 23. Alternatively, a single computer may be provided capable of executing the commands of the computer program. Additionally, a computer-readable storage medium comprising commands is provided, which, when executed by a computer, causes the computer to execute the steps of the outlined method, or, when executed by the control computer 21 and the simulation computer 23, causes the control computer and the simulation computer to execute the steps of the outlined method.
[0031] As already outlined, a simulation model 19 representing the test bench 3 and its movable sections relative to each other is provided. The simulation model 19 is stored electronically in the data memory of the simulation computer 23. Also as already outlined, a setpoint value for the movement of the first section of the test bench 3 (i.e., the movement of the first clamping element 7) is determined. This setpoint value is stored electronically in the data memory of the control computer 21 and is one of a plurality of setpoint values that together form part of a test scheme stored in the data memory of the control computer 21. To determine this setpoint value, before performing movement of the first clamping element 7 based on this setpoint value, the setpoint value is read from the data memory of the control computer 21 by its processor, and a setpoint value signal representing this setpoint value is sent from the control computer 21 to the simulation computer 23. The processor and data memory of the simulation computer 23 are used to move the simulated first clamping element based on the setpoint value determined in the simulation model 19. As the simulated first clamping element moves based on the determined setpoint value, the distance between the simulated first clamping element and the simulated frame is determined continuously or at regular intervals (e.g., at a specified time interval or after a specified movement length has been covered).
[0032] For each determined distance, the simulation computer 23 compares the determined distance with the specified minimum distance. When each determined distance is equal to or greater than the specified minimum distance, the simulation computer 23 sends a first distance signal indicating that each determined distance is equal to or greater than the specified minimum distance to the control computer 21. When at least one determined distance is less than the specified minimum distance, the simulation computer 23 sends a second distance signal indicating that at least one determined distance is less than the specified minimum distance to the control computer 21. Depending on whether the control computer 21 receives the first or second distance signal for the setpoint value: if the control computer 21 receives the first distance signal, it sends a control signal to the test bench 3 causing the first clamping element 7 to move based on the determined setpoint value; and if the control computer 21 receives the second distance signal, it does not send the corresponding control signal to the test bench 3, and thus prevents the first clamping element 7 from moving based on the determined setpoint value, or the first clamping element 7 does not move.
[0033] When at least one determined distance is less than the specified minimum distance, the simulation computer 23 adjusts the determined setpoint value. The processor and data memory of the simulation computer 23 are used to move the simulated first clamping element based on the adjusted setpoint value in the simulation model 19. As the simulated first clamping element moves based on the adjusted setpoint value, the distance between the simulated first clamping element and the simulation frame is determined continuously or at regular intervals (e.g., at a specified time interval or after a specified movement length has been covered).
[0034] For each determined distance, the simulation computer 23 compares that distance with the specified minimum distance. When each determined distance is equal to or greater than the specified minimum distance, the simulation computer 23 sends a first distance signal indicating that each determined distance is equal to or greater than the specified minimum distance to the control computer 21. When at least one determined distance is less than the specified minimum distance, the simulation computer 23 sends a second distance signal indicating that at least one determined distance is less than the specified minimum distance to the control computer 21. Depending on whether the control computer 21 receives the first or second distance signal for the adjusted setpoint value: if the control computer 21 receives the first distance signal, it sends a control signal to the test bench 3 causing the first clamping element 7 to move based on the adjusted setpoint value; and if the control computer 21 receives the second distance signal, it does not send the corresponding control signal to the test bench 3, thus preventing the first clamping element 7 from moving based on the adjusted setpoint value, or preventing the first clamping element 7 from moving.
[0035] Figure 2The arrangement of test bench 3 is shown, and... Figure 1 Compared to the arrangement of the test bench 3, the first clamping element 7 has moved based on the first determined setpoint value, because after the movement of the simulated first clamping element, the simulation model 19 has first been used to determine that the distance between the simulated first clamping element and the simulation frame is equal to or greater than the specified minimum distance. Figure 2 The simulation model 19 is shown for moving the simulated first clamping element based on a second determined setpoint value, and the distance between the simulated first clamping element and the simulation frame is less than the specified minimum distance (shown by a circle), and thus prevents the first clamping element 7 from moving based on the second determined setpoint value.
[0036] Furthermore, it should be noted that "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude a plurality. Additionally, it should be noted that features described with reference to one of the exemplary embodiments described above may also be used in combination with other features of the other exemplary embodiments described above.
