The method for detecting the deviation of the warehouse material pile is based on a warehouse material pile deviation detection system as shown in figure 1, and the system comprises a detection device A, a carrying device B and a control system for implementing the method for detecting the deviation of the warehouse material pile.
As shown in fig. 2, the detection device a comprises a surface scanning unit a01 and an adjusting unit a02, the number of the surface scanning units a01 is equal to the number of the side portions of the pile to be detected, and the surface scanning units a01 and the adjusting unit a02 are arranged in a one-to-one correspondence manner; each of the area scanning units a01 corresponds to an adjustment unit a02 for adjusting the position thereof. The surface scanning unit a01 can emit detection light (which may be visible light or invisible light) and receive reflected light of the detection light reflected by an external object, and the light emitting unit of the surface scanning unit a01 can rotate to scan the whole detection surface. Preferably, the surface scanning unit a01 is a laser radar, and the adjusting unit a02 is a linear module.
The carrying device B is used for carrying the stacked pallet from a stacking position to a detection point, the surface scanning unit A01 and the adjusting unit A02 of the detection device A are arranged above the detection point, and the carrying device B can be in the form of a carrying robot, a traction robot and the like. The graphic representation is a transfer robot, the transfer robot transfers the pallet through the transport frame C, the transfer robot moves in a two-dimensional code navigation mode, two-dimensional codes are arranged on the ground of the stacking position and the detection point, and a camera arranged downwards is mounted on the transfer robot.
In the actual operation process, the scheduling carrying device B moves to the stacking position in a two-dimensional code navigation mode and adjusts the posture of the carrying device B according to the position of the two-dimensional code in the image acquired by the camera. There may be two situations in the above process, the first: the carrying device B can carry the empty transport rack C to a stacking position to receive stacking (a stacking robot at the stacking position places the pallet and warehouse logistics on the transport rack C); and the second method comprises the following steps: the transport frame C is originally placed at the stacking position, the pallet is arranged on the transport frame C, the stacked stack is loaded on the pallet, and the transport frame C at the stacking position is jacked up after the carrying device B moves to the stacking position. And then, the dispatching and carrying device B carries the transport rack C with the pile to move to a detection point in a two-dimensional code navigation mode, the position is determined through the two-dimensional code of the detection point, and the posture of the carrying device B is adjusted by means of the position of the two-dimensional code in an image acquired by a camera. After the detection is finished, if the detection is qualified, the dispatching and carrying device B leaves the detection point and goes to the target position in a two-dimensional code navigation mode, and the pallet fork on the transport frame C is taken down through the forklift at the target position.
The plane scanning unit a01, the adjusting unit a02 and the carrying device B are all communicatively connected to a control system, where the control system is a general term and may include a plurality of core units such as processors and memories, each processor may execute its own task and the processors may communicate with each other, and in the above system, the control system may include a scheduling center for scheduling the carrying device B to operate and a control module connected to the plane scanning unit a01 and the adjusting unit a02, and the scheduling center and the control module may communicate with each other.
Based on the above detection system, as shown in fig. 3, the method for detecting the deviation of the warehouse material pile of the invention comprises the following steps S101-S104:
step S101, acquiring the scanning data of each surface scanning unit A01; the number of the surface scanning units A01 is multiple, and the surface scanning units A01 are respectively used for scanning each side part of the detected pile;
in this step, generally, the number of the lateral portions of the detected pile is four, that is, the lateral portions correspond to four face scanning units a01, the detection faces of each face scanning unit a01 are vertical planes, an accommodating well for accommodating the pile is formed between the four detection faces corresponding to the four face scanning units a01, and the detected pile is placed in the accommodating well during detection. If the pile is laid, there is a gap between each side of the pile and the detection surface corresponding to that side.
Step S102, judging whether the scanning data has abnormal data or not to obtain a judgment result;
in this step, it is determined whether or not there is abnormal data, that is, whether or not each side of the pile interferes with the detection surface of the surface scanning unit a01 at the corresponding position, and if interference occurs, the material in the pile is blocked by the detection light emitted from the surface scanning unit a01, that is, abnormal data is generated.
Step S103, when the judgment result is yes, executing a first processing flow;
in this step, the first processing flow may be a flow of outputting information or instructions to a human or processing device. If the prompt information is manually output, the content of the output prompt information comprises event information, the side position of the abnormal position, specific coordinates of the abnormal position and the like, the event information is that the deviation exceeds the range, the side position of the abnormal position represents that the side of the pile is abnormal, and the specific coordinates of the abnormal position represent the detailed position of the side of the pile interfering with the detection surface. In addition, the system can visually output prompt information through a visual interface, and can visually mark the abnormal position in the stack image so as to facilitate manual processing. If the task information is output to processing devices such as the stacking robot and the like, the task information comprises the side position of the abnormal position, the specific coordinate of the abnormal position and the like, and the subsequent scheduling stacking robot partially unstacks the materials forming the stack according to the abnormal position and re-stacks the materials.
And step S104, when the judgment result is negative, executing a second processing flow.
In this step, since the detected pile is moved into and out of the detection point by the carrying device B, the method further includes, before the step S101, the steps of: scheduling a carrying device B to carry the detected stack to a detection point; correspondingly, the second processing flow specifically includes: and dispatching the carrying device B to carry the detected stack out of the detection point and to the target position.
In the above steps S101-S104, the plurality of surface scanning units a01 simultaneously scan the detection surfaces, so that the detection of the side portions of the pile can be performed simultaneously, the detection can be performed comprehensively, and the occurrence of situations such as troublesome deviation of the pile or inclination of the pile can be effectively prevented.
Since the warehouse materials have different dimensions when entering or exiting the warehouse, the dimensions of the stacked piles are different, and therefore, the following steps S201 to S203 are preferably included before the scanning data of each surface scanning unit a01 is acquired in step S101:
step S201, acquiring the theoretical size of the detected pile; the theoretical size is input manually in advance, or is calculated in advance by the control system and stored in the memory, or can be inquired or called from other systems.
Step S202, determining the target position of each surface scanning unit A01 according to the theoretical size;
in step S203, the adjustment unit a02 corresponding to each of the surface scanning units a01 is driven to operate so that each of the surface scanning units a01 reaches a target position.
In the above steps S201 to S203, the position of the surface scanning unit a01 is adjusted by controlling the adjustment unit a02 according to the theoretical size, so that the detection system can effectively adapt to piles of different sizes and specifications, and has strong adaptability.
The step S202 of determining the target position of each of the area scanning units a01 according to the theoretical size includes the following steps S301 to S302:
step S301, calculating the position of the detection surface corresponding to each side part according to the theoretical size and the maximum allowable deviation value;
step S302 calculates the position of the surface scanning unit a01 based on the position of the detection surface.
Steps S301 to S302 are to move the side surface of the ideal pile outward by the maximum allowable deviation value to obtain a detection surface based on the theoretical size, and then determine the position of the surface scanning unit a01 according to the detection surface.
Preferably, the step S103 of determining whether the scan data has abnormal data includes: and judging whether each distance value contained in the scanning data falls into a preset value range, if so, indicating that the scanning data has abnormal data. After the surface scanning unit A01 finishes one period of scanning on the detection surface, a dot matrix data sequence is obtained, each data in the dot matrix data sequence is a distance value corresponding to a specific angle, a numerical range corresponding to each specific angle is prestored in a memory of a control system, the control system judges whether each distance value in the dot matrix data sequence falls in the corresponding numerical range, if yes, the distance value is abnormal data, and if only one abnormal data exists, the interference phenomenon exists between the side part of the pile and the detection surface, and the pile stacking does not meet the requirement.
In addition, since the carrying device B inevitably has a position deviation when the palletizing position and the detection point are positioned and stopped, in order to avoid the position deviation of the carrying device B stopped from subsequently affecting the detection of the stack, the step S101 further includes the following steps S401 to S402:
step S401, after the carrying device B stops at the stacking position, calculating a first stop deviation of the carrying device B relative to the stacking position according to an image which is obtained by a camera on the carrying device B and contains a two-dimensional code;
step S402, after the carrier B stops at the detection point, calculating a second stop deviation of the carrier B relative to the detection point according to an image which is obtained by a camera on the carrier B and contains the two-dimensional code;
step S403, obtaining a total parking deviation according to the first parking deviation and the second parking deviation, calculating a position compensation value corresponding to each surface detection unit according to the total parking deviation, and driving each adjusting unit to operate according to the position compensation value to correct the position of each surface detection unit.
Through the steps, before each pile is detected, the position of the opposite detection unit is supplemented and corrected once according to the actual situation, and the error detection caused by the position deviation of the stop of the carrying device B can be effectively avoided.
