Summary of the application
The handling equipment who uses at present adopts the part of truss manipulator to snatch the goods usually, uses the truss manipulator to snatch the part from the transfer chain and places appointed buttress position. Usually, in order to improve the gripping efficiency, two trusses are arranged in one direction. However, when two trusses work simultaneously, the two trusses may generate interference collision, and the inventor finds a method for preventing interference collision when studying whether the two trusses may generate interference collision: whether interference collision occurs or not is determined according to the task tracks executed by the two trusses, then if interference collision occurs, one truss executes the task first, and after the task is completed, the other truss executes the task again. However, although this method can prevent interference collision, the two trusses do not collide during the whole execution process although they interfere collision, and the two trusses can completely have a space for executing tasks together, so if only the task tracks are overlapped, one truss executes the task first, and after the task is finished, the other truss starts executing the task, although interference collision can be prevented, the operation efficiency is not high.
Therefore, according to the avoidance control method of the common rail multi-truss system, in the multi-truss operation process, the motion mode is determined according to the current working states of the two adjacent trusses in real time, whether the two trusses are interfered and collided or not is determined according to the motion mode and the current working states, when the two trusses are not interfered and collided, the current motion state is maintained to continue to work, and when the interfered and collided, the working state of at least one truss in the two trusses is regulated and controlled, so that the two trusses can work simultaneously, collision does not occur, and the operation efficiency of the multi-truss system is improved.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Exemplary System
An embodiment of the application provides a rail many trusses altogether includes: two guide brackets which are arranged in parallel and a plurality of trusses which are parallel to each other, the trusses can move along the length direction of the two guide brackets.
Specifically, the number of the trusses included in the common rail multi-truss may be 2 or 3, and the number of the trusses included in the common rail multi-truss is not limited in the present application.
Specifically, fig. 1 is a schematic structural diagram of a common rail multi-truss according to an embodiment of the present application, and as shown in fig. 1, the number of trusses in the common rail multi-truss is 2, that is, the common rail multi-truss is a common rail double-truss, and the common rail double-truss 1 includes: a first guide bracket 10, a second guide bracket 11, a first truss 12 and a second truss 13. The first guide support 10 and the second guide support 11 are parallel to each other, two ends of the first truss 12 and two ends of the second truss 13 are respectively installed on the first guide support 10 and the second guide support 11, and both the first truss 12 and the second truss 13 can move along the length direction of the first guide support 10 and the second guide support 11. First truss 12 and second truss 13 are parallel to each other, and first truss 12 and first guide bracket 10 are perpendicular to each other.
Specifically, the first truss 12 and the second truss 13 can be moved along the length direction along the first guide bracket 10 and the second guide bracket 11 by the moving assembly. For example: first guide way is seted up to first guide bracket 10 up the up end, and the second guide way is seted up to second guide bracket 11 up the up end, and the length extending direction of first guide way is parallel with the length extending direction of first guide bracket 10, and the length extending direction of second guide way is parallel with the length extending direction of second guide bracket 11. Wheels are arranged at two ends of the first truss 12, the two wheels at the two ends are respectively located in the first guide groove and the second guide groove, and the two wheels respectively slide in the first guide groove and the second guide groove, so that the first truss 12 can move along the first guide support 10 and the second guide support 11. Similarly, the movement of the second girder 13 along the first and second guide brackets 10 and 11 may be implemented in the same manner as the movement of the first girder 12 along the first and second guide brackets 10 and 11 described above.
When the first truss 12 and the second truss 13 actually execute tasks, a grabbing device is fixed below the first truss 12, and a grabbing device is fixed below the second truss 13; after the grasping apparatus grasps the goods, the first girder 12 moves along the first guide bracket 10 and the second guide bracket 11 so that the goods can be transported to the destination and then dropped. However, the first truss 12 and the second truss 13 both move on the first guide bracket 10 and the second guide bracket 11, and therefore, an interference collision phenomenon may occur, and thus, the present application provides an avoidance control method for a common rail multi-truss system.
Exemplary method
Fig. 2 is a schematic flow chart of an avoidance control method for a common rail multi-truss according to an embodiment of the present application, and as shown in fig. 2, the avoidance control method for a common rail multi-truss includes the following steps:
step S10: determining the motion mode of two trusses according to the current working state of two adjacent trusses in the plurality of trusses;
because two adjacent trusses can move along the length direction of the first guide support 10 and the second guide support 11, in the moving process of the trusses, the avoidance of the whole common rail trusses can be regulated and controlled by regulating and controlling the avoidance of the two adjacent trusses.
Specifically, taking the common rail double truss shown in fig. 1 as an example, step S10 is: in the process of executing tasks by the first truss 12 and the second truss 13, determining the motion mode of the first truss 12 according to the current working state of the first truss 12 in real time, and determining the motion mode of the second truss 13 according to the current working state of the second truss 13;
specifically, the current operating state includes, but is not limited to: target position information, current movement speed, current position information on the first guide bracket 10 (i.e., the current specific position where the first girder 12 moves to the first guide bracket 10). The target location information is then: when the current task executed by the grabbing device corresponding to the first truss 12 is to grab the goods, the target position information is the position of the goods to be grabbed by the current task; when the current task of the gripping device corresponding to first truss 12 is to deliver the gripped goods to the shelf, the target position information is the position of the shelf.
Specifically, the motion mode includes a close mode, a distant mode, and a still mode. The static mode refers to a static state, for example, the first truss 12 is currently in a static state, and the second truss 13 is currently in a static state.
Specifically, taking the common rail double truss shown in fig. 1 as an example, the approach mode and the distance mode may be determined in the following manner: the approaching mode is a motion mode gradually approaching the reference object 14, and the departing mode is a motion mode gradually departing from the reference object 14. The reference object 14 is different in the close mode and the far mode, as shown in fig. 3 to 5: the common rail double truss further comprises a plurality of fixing rods 15, the fixing rods 15 are fixed below the first guide bracket and the second guide bracket, and the length extending direction of the fixing rods 15 is perpendicular to the length extending direction of the first guide bracket and the length extending direction of the first truss 12. Fig. 3 shows a specific expression of the distance mode and the approach mode of the first truss 12 and the second truss 13, when the fixing rod 15 at the intermediate position is used as the reference object 14. Referring to the fixing rod 15 at the left end position as a reference 14, the first truss 12 and the second truss 13 are embodied in a distant mode and an approaching mode as shown in fig. 4. A specific expression of the distance mode and the approach mode of the first girder 12 and the second girder 13 when the fixing rod 15 at the right end position is used as the reference 14 is shown in fig. 5.
Step S20: determining whether the two trusses are interfered and collided according to the motion modes of the two trusses and the current working state; when the two trusses are determined to generate interference collision, executing the step S30; when it is determined that the two trusses do not have an interference collision, step S40 is performed.
Step S30: when the two trusses are interfered and collided, the working state of at least one truss in the two trusses is regulated and controlled according to the current working state of the two trusses.
Specifically, taking the common rail double truss shown in fig. 1 as an example, the working states may include: target position information, movement speed; when the first truss 12 and the second truss 13 may have an interference collision, the operating state of the first truss 12 and/or the second truss 13 is controlled, for example, the moving speed of the first truss 12 and/or the second truss 13 is controlled to be 0 (i.e., stationary), or the target position information of the first truss 12 and/or the second truss 13 is controlled.
Namely, when the first truss 12 and the second truss 13 are interfered and collided, the working state of one truss or two trusses of the two trusses is adjusted in real time, so that the first truss 12 and the second truss 13 are not interfered and collided, the first truss 12 and the second truss 13 can work simultaneously, collision does not occur, and the operating efficiency of the double-truss system is improved.
Step S40: and maintaining the two trusses to work continuously in the current working state.
Namely, when the two trusses are determined not to generate interference collision, the movement state of any truss is not required to be regulated and controlled, and the task is continuously executed according to the original movement speed and the target position information.
The application provides a control method for avoiding a common rail multi-truss system, in the running process of a plurality of trusses, a motion mode is determined according to the current working states of two adjacent trusses in real time, whether interference collision can occur between the two trusses is determined according to the motion mode and the current working states, when the interference collision cannot occur between the two trusses, the current motion state is maintained to continue working, when the interference collision can occur, the working state of at least one truss in the two trusses is regulated and controlled, so that the two trusses can work simultaneously, collision does not occur, and the running efficiency of the multi-truss system is improved.
Because the plurality of trusses can move along the length direction of the first guide support 10 and the second guide support 11, in the moving process of the plurality of trusses, the avoidance of the whole common rail multi-truss can be regulated and controlled by regulating and controlling the avoidance of two adjacent trusses. Taking the common rail double trusses shown in fig. 1 as an example, the avoidance control method of two trusses in the common rail double trusses is described in detail below. When the multiple trusses comprise at least 3 trusses, the avoidance control method between two adjacent trusses is the same as the avoidance control method of two trusses in the common rail double trusses.
In one possible implementation manner, as shown in fig. 6, the specific determination method of the motion modes of the two trusses may be determined by: that is, step S10 (determining the motion mode of the two trusses according to the current working states of the two trusses) specifically includes the following steps:
step S101: determining the current distance between the truss and the reference object 14 according to the current position information of the truss on the guide bracket at the current moment;
the position information of the girder on the guide bracket can be detected according to the position sensor arranged on the girder.
Step S102: determining a reference distance between the truss and the reference object 14 according to reference position information of the truss on the guide support at the previous moment, wherein the time length between the previous moment and the current moment is equal to the detection period of the position sensor;
for example, the detection period of the position sensor is 1 second, and the reference position information at the previous time is the reference position information of the truss on the guide bracket before 1 second.
The time interval is set as the detection period of the position sensor, and the time interval of the position sensor is usually counted in seconds, such as 1 second, 0.5 second and the like, so that in one detection period, the truss does not complete one execution task, the movement distance is not too far, and the accuracy of the movement mode judgment is improved.
Step S103: judging whether the current distance is equal to the reference distance or not;
when the determination result in step S103 is yes, that is, when the current distance is equal to the reference distance, it indicates that there is no change in distance between the truss and the reference object 14, that is, the truss is at rest at this time, that is, the movement mode of the truss is the rest mode, and step S104 is performed.
If the result of the determination in step S103 is no, it means that the distance between the truss and the reference object 14 is gradually changing, and step S105 is executed.
Step S105: judging whether the current distance is greater than a reference distance;
when the determination result in step S105 is yes, that is, when the current distance is greater than the reference distance, it indicates that the truss gradually moves away from the reference object 14, that is, the movement mode of the truss is a away mode, and step S106 is performed.
When the determination result in step S105 is no, that is, when the current distance is smaller than the reference distance, it indicates that the truss gradually approaches the reference object 14, that is, the movement mode of the truss is the approach mode, and step S107 is performed.
Step S106: and determining the movement mode of the truss as a far mode.
Step S107: a motion pattern of the truss is determined to be proximate to the pattern.
In another possible implementation manner, as shown in fig. 7, the specific determination method of the motion modes of the two trusses may also be determined by: that is, step S10 (determining the motion mode of the two trusses according to the current working states of the two trusses) specifically includes the following steps:
step S11: constructing a plane coordinate system by taking the central point in the length direction of the guide support as an original point O, wherein as shown in FIG. 8, the Y axis of the plane coordinate system is parallel to the length of the guide support, and the X axis of the plane coordinate system is parallel to the length of the truss; the right end of the origin O is taken as a positive Y axis, and the left end of the origin O is taken as a negative Y axis.
The reference object 14 is the center point O, and when a fixing rod 15 is fixed just below the center point, the fixing rod 15 can also be the reference object 14.
Step S12: and judging whether the current speed of the truss is 0 or not, and when the current speed of the truss is 0, indicating that the movement mode of the truss is a static mode. I.e. step S13 is performed.
Specifically, the moving speed of the truss may be detected by a speed sensor provided on the truss.
Step S13: determining the movement mode of the truss as a static mode;
when the judgment in step S12 is not 0, it indicates that the truss is moving. Step S14 is performed.
Step S14: acquiring current coordinate information of the truss on the guide support and target coordinate information of the truss;
the current coordinate information specifically refers to current Y-axis coordinate information of the truss on the guide support.
Specifically, the current coordinate information of the truss on the guide bracket may be determined as follows: and a position sensor is arranged on the truss, and when the truss moves on the guide support, the position sensor detects the current position information of the truss on the guide support in real time, and then the current position information is converted by using a coordinate system, so that the current coordinate information of the truss is determined.
Step S15: judging whether the target coordinate information and the current coordinate information of the truss are both positioned on a positive Y axis or a negative Y axis;
when the determination result in the step S15 is yes, that is, whether the target coordinate information and the current coordinate information of the truss are both located on the positive Y axis or the negative Y axis, that is, the target coordinate information and the current coordinate information of the truss are both located on the same side of the origin O, at this time, the motion mode of the truss may be determined according to the sizes of the target coordinate information and the current coordinate information. I.e. steps S16-S18 are performed.
When the determination result in step S15 is negative, that is, the target coordinate information and the current coordinate information of the truss are located on the positive Y axis and the negative Y axis, respectively, at this time, when the truss performs the task, the truss gradually approaches the origin O, that is, the current motion mode of the truss is an approach mode, that is, step S18 is performed. However, when the truss performs the task, the truss is close to the origin O and then gradually moves away from the origin O. For example, as shown in fig. 9, the current coordinate information of first girder 12 is located on the negative Y-axis, and the target coordinate information is located on the positive Y-axis, and at this time, first girder 12 needs to be close to origin O in order to complete the task, and thus the current movement pattern of first girder 12 is the approach pattern. However, during the process of continuing to perform the task on first truss 12, first truss 12 gradually gets closer to point O and then gradually gets farther from point O, that is, after first truss 12 moves to the right end of point O, the movement pattern of first truss 12 is the far pattern, as shown in fig. 10.
Step S16: judging whether the absolute value of the target coordinate information is larger than the absolute value of the current coordinate information;
when the determination result of step S16 is yes, that is, the target coordinate information is farther from the origin O with respect to the current coordinate information, the truss will be farther from the origin O, and therefore, the movement mode of the truss is the distant mode, that is, step S17 is performed.
When the determination result of step S16 is no, that is, the target coordinate information is closer to the origin O with respect to the current coordinate information, the truss will be closer to the origin O and thus the movement pattern of the truss is the approach pattern, that is, step S18 is performed.
Step S17: determining the movement mode of the truss as a far mode;
step S18: determining the movement mode of the truss as a proximity mode;
for example, as shown in fig. 8, the target coordinate information and the current coordinate information of the first girder 12 are both located on the negative Y-axis, and the absolute value of the target coordinate information is larger than that of the current coordinate information, so that the movement mode of the first girder 12 is the distant mode.
The target coordinate information and the current coordinate information of the second truss 13 are both located on the positive Y-axis, and the absolute value of the target coordinate information is smaller than the absolute value of the current coordinate information, so the motion mode of the second truss 13 is the approach mode.
It should be noted that, during the process of executing a task, the movement mode of one truss is not only one, and the movement mode of the truss is determined according to the current position, the reference object 14 and the target position, as shown in fig. 8 and 9.
In a possible implementation manner, after determining the movement patterns of first truss 12 and second truss 13 by using the manner of determining the movement patterns of the trusses shown in fig. 7, it is determined whether an interference collision occurs between first truss 12 and second truss 13, and if an interference collision occurs, the specific control manner may be as follows:
(1) As shown in fig. 11, step S20 (determining whether the two trusses will have an interference collision according to the motion mode and the current working state of the two trusses) may specifically include the following steps:
step S201: determining the motion mode of the first truss 12 as a proximity mode and the motion mode of the second truss 13 as a static mode;
step S202: judging whether the target coordinate information Y4 of the first truss 12 is larger than the current coordinate information Y2 of the second truss 13;
when the determination result in step S202 is yes, as shown in fig. 12, that is, the target coordinate information Y4 of the first truss 12 is greater than the current coordinate information Y2 of the second truss 13, that is, it is explained that the destination of the first truss 12 is located at the right end of the second truss 13, and therefore, the first truss 12 and the second truss 13 may have an interference collision, that is, step S203 is performed.
When the judgment result of step S202 is no, as shown in fig. 13, that is, the target coordinate information Y4 of the first girder 12 is less than or equal to the current coordinate information Y2 of the second girder 13, step S204 is performed.
Step S203: determining that an interference collision will occur between first truss 12 and second truss 13;
step S204: judging whether the absolute value of the difference between the target coordinate information Y4 of the first truss 12 and the current coordinate information Y2 of the second truss 13 is smaller than a preset safety distance; namely, it is determined whether the distance L2 between the target coordinate information of the first truss 12 and the current coordinate information of the second truss 13 is smaller than the preset safety distance L.
When the determination result in step S204 is yes, that is, the absolute value of the difference between the target coordinate information Y4 of the first truss 12 and the current coordinate information Y2 of the second truss 13 is smaller than the preset safe distance, that is, L2 < L, it indicates that the process of moving the first truss 12 to the destination does not pass through the current position of the second truss 13, but because the distance between the current positions of the second trusses 13 in the destination area of the first truss 12 is smaller than the preset safe distance, because inertia exists during the movement of the first truss 12, when the first truss 12 is in operation at the destination, an interference collision may still occur with the second truss 13, and therefore, it is determined that the interference collision occurs between the first truss 12 and the second truss 13, that is, step S203 is performed.
When the determination result in step S204 is no, that is, the absolute value of the difference Y2 between the target coordinate information Y4 of the first truss 12 and the current coordinate information of the second truss 13 is greater than or equal to the preset safe distance, that is, L2 is greater than or equal to L, it indicates that even if there is inertia in the movement of the first truss 12, there is still enough distance for buffering when the first truss 12 is in operation and the destination is reached, so that the first truss 12 and the second truss 13 do not collide with each other, that is, step S205 is performed.
Step S205: it is determined that first truss 12 and second truss 13 will not collide in an interference manner.
When step S203 determines that the first truss 12 and the second truss 13 are in interference collision, step S30 (adjusting and controlling the working state of at least one of the two trusses according to the current working states of the two trusses) specifically includes the following steps:
step S301: the second truss 13 is regulated and controlled to move to the position of the regulation and control coordinate information, and the absolute value of the difference between the regulation and control coordinate information Y3 and the target coordinate information Y4 of the first truss 12 is greater than or equal to the preset safety distance;
that is, as shown in fig. 12 and 13, a distance L1 between the target coordinate information and the regulation coordinate information is greater than or equal to the preset safety distance L.
Because the second truss 13 is in the static mode, the second truss 13 executes a specific avoidance mode, gives back to the coordinate information for regulation and control, and gives enough running space to the first truss 12, so that the first truss 12 does not interfere and collide with the second truss 13 in the task execution process, the working state of each truss is utilized to the maximum extent, and the running efficiency is improved.
Step S302: and (3) controlling the first truss 12 to continue to move in the current movement state, namely, the first truss 12 continues to maintain the original movement speed to move to the destination.
(2) As shown in fig. 14, the step S20 (determining whether the two trusses will have interference collision according to the motion mode and the current working state of the two trusses) may specifically include the following steps:
step S21: determining the movement mode of the first truss 12 as a close mode and the movement mode of the second truss 13 as a far mode;
step S22: judging whether the target coordinate information Y4 of the first truss 12 is smaller than the target coordinate information Y5 of the second truss 13;
when the judgment result of step S22 is yes, i.e., Y4 < Y5, as shown in fig. 15; step S23 is performed.
When the judgment result in step S22 is no, that is, Y4 is greater than or equal to Y5, as shown in fig. 16, that is, first truss 12 passes through the destination of second truss 13 in the process of executing the task, at this time, it is determined that interference collision occurs between first truss 12 and second truss 13, and step S24 is executed.
Step S23: judging whether the absolute value of the difference between the target coordinate information of the first truss 12 and the target coordinate information of the second truss 13 is smaller than a preset safety distance or not;
if the result of the determination in step S23 is yes, that is, | Y4-Y5| = L3 < L, that is, if the first truss 12 and the second truss 13 normally perform tasks, since both the first truss 12 and the second truss 13 have inertia during the movement, even if the first truss 12 and the second truss 13 reach the destination, an interference collision may still occur due to the inertia of each other. Thus, step S24 is performed.
When the interpretation result in step S23 is no, that is, | Y4-Y5| ≧ L, that is, when first truss 12 and second truss 13 normally perform a task, even if both first truss 12 and second truss 13 have inertia during movement, there is sufficient buffer space when first truss 12 and second truss 13 reach the destination, and therefore, interference collision does not occur between first truss 12 and second truss 13, and step S25 is performed.
Step S24: it is determined that the first truss 12 and the second truss 13 will have an interference collision.
Step S25: it is determined that the first truss 12 and the second truss 13 do not have an interference collision.
When it is determined in step S24 that the first truss 12 and the second truss 13 are subjected to interference collision, step S30 (controlling the motion state of at least one of the two trusses according to the current working states of the two trusses) specifically includes the following steps:
step S31: the first truss 12 is regulated and controlled to move to the regulation and control coordinate information Y3, the regulation and control coordinate information Y3 is smaller than the target coordinate information Y5 of the second truss 13, that is, Y3 is smaller than Y5, and an absolute value of a difference between the regulation and control coordinate information Y3 and the target coordinate information Y5 of the second truss 13 is greater than or equal to a preset safe distance L, that is, | Y3-Y5| = L1 is greater than or equal to L, as shown in fig. 15 and fig. 16;
that is, when the first truss 12 and the second truss 13 are subjected to interference collision, the first truss 12 is controlled to move to the control coordinate information.

step S35: the first truss 12 is regulated to continue moving.
(3) As shown in fig. 17, the step S20 (determining whether the two trusses will have interference collision according to the motion mode and the current working state of the two trusses) may specifically include the following steps:
step S26: determining the motion mode of the first truss 12 as an approach mode and the motion mode of the second truss 13 as an approach mode;
i.e. the direction of movement of first girder 12 and second girder 13 is identical.

as shown in fig. 18, when the determination result in step S27 is yes, that is, | Y4-Y5| = L3 < L, after the first truss 12 and the second truss 13 move to the respective destinations, the safe distance is insufficient, so that the first truss 12 and the second truss 13 still have an interference collision, that is, step S28 is performed.
If the determination result in step S27 is no, that is, | Y4-Y5| = L3 ≧ L, after the respective moving destinations of first truss 12 and second truss 13, since the safety distance is sufficient, interference collision does not occur between first truss 12 and second truss 13, that is, step S29 is performed.
Step S28: it is determined that the first truss 12 and the second truss 13 will have an interference collision.
Step S29: it is determined that the first truss 12 and the second truss 13 do not have an interference collision.
When it is determined that the first truss 12 and the second truss 13 are interfered and collided, the step S30 (controlling the motion state of at least one of the two trusses according to the current working states of the two trusses) specifically includes the following steps:
step S36: determining an absolute value of a first movement distance L1 according to current coordinate information Y1 of the first truss 12 and target coordinate information Y4 of the first truss 12;
step S37: determining an absolute value of a second movement distance L2 according to the current coordinate information Y2 of the second truss 13 and the target coordinate information Y5 of the second truss 13;
step S38: judging whether the first movement distance is smaller than the second movement distance;
when the judgment result of step S38 is yes, i.e., the first movement distance is smaller than the second movement distance, i.e., L1 < L2, steps S39 to S391 are performed.
When the determination result of step S38 is no, that is, the first movement distance is greater than or equal to the second movement distance, that is, L1 is greater than L2, step S392 is performed.
Step S39: regulating and controlling the first truss 12 to continuously move to the target coordinate information of the first truss 12 in a proximity movement mode;
step S391: the second truss 13 is regulated and controlled to move continuously to the regulation and control coordinate information Y3 and then to be stationary, the absolute value of the difference between the regulation and control coordinate information Y3 of the second truss 13 and the target coordinate information Y4 of the first truss 12 is greater than or equal to the preset safe distance L, that is, | Y4-Y3| = L1 is greater than or equal to L, as shown in fig. 18;
when the first truss 12 reaches the destination, the first truss 12 stops, and the second truss 13 moves to the destination from the control coordinate information Y3.
Step S392: and controlling the first truss 12 to continuously move to the position of the control coordinate information Y3 and then to be static, and controlling the second truss 13 to continuously move to the position of the target coordinate information of the second truss 13.
