Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, not all, embodiments of the present invention.
At present, the carrying equipment is widely applied to the fields of e-commerce, intelligent factories and the like, and there are AGVs (Automated Guided vehicles), stackers, forklifts, shuttles and the like, wherein safety and stability are the most basic and important performance indexes of the carrying equipment. The AGV robot is taken as an example for explanation, in most application scenarios, in order to more efficiently apply available space in a field, a mode of reducing the width of a runway required by the AGV robot as much as possible under the condition that the AGV robot can safely operate is mostly adopted by a user, so that the purpose of more fully utilizing the available space in the application field is achieved. In practical application, the narrower the runway width in the application field, the higher the requirements on the running performance and the safety performance of the AGV robot are. However, in the running process of the AGV robot, the container driven by the AGV robot is prone to be deviated, it is difficult to ensure that the container driven by the AGV robot is in a positive state with the runway (that is, the target direction of the container is consistent with the direction of the runway), and once the container is in a skew state (the target direction of the container is not consistent with the direction of the runway), the occupied space of the container is prone to extend to other runways, which easily causes the two AGV robots to collide with each other when meeting each other. Therefore, in the moving process of the AGV robot, the cargo container driven by the AGV robot is ensured to be positioned in the runway, and the safety of the AGV robot is very important.
In some embodiments, the AGV robot corrects the angle between the AGV robot and the container carried by the AGV robot only when the AGV robot encounters a rotation. In other embodiments, some AGV robots properly correct the angle between the AGV robot and the container carried by the AGV robot during the moving process, but this solution is essential to keep the heading of the AGV robot consistent with the target direction of the container of the AGV robot, and once the heading of the AGV robot deviates slightly from the runway, the container is correspondingly carried to be in a skewed state relative to the runway. Therefore, the above solutions cannot ensure that the AGV robot keeps the container in the runway all the time during the operation process, so that the robots in different runways may have potential safety hazards such as container collision. To improve this problem, embodiments of the present invention provide a method and an apparatus for adjusting a storage container, and a transportation device, which are applicable to a scenario where a transportation device needs to be applied, such as a warehousing scenario, and the following detailed description of the embodiments of the present invention is provided.

Example two:
to facilitate understanding of the embodiments of the present invention, a detailed description will be first provided for an adjusting method of a cargo container disclosed in the embodiments of the present invention, where the adjusting method is performed by a carrying device, where the carrying device is configured to drive the cargo container to move, and the driving manner may be, for example, lifting driving or pushing and pulling driving. The storage container according to the embodiment of the present invention is, for example, a tray, a bin, a shelf, or the like, and the embodiment of the present invention is not limited thereto.
For convenience of understanding, the embodiment of the present invention is described by taking a carrying device for lifting a container as an example, and referring to a schematic diagram of a carrying device for lifting a container shown in fig. 2, a left oblique line covered area in fig. 2 represents a carrying device, a right oblique line covered area represents a container, and a container is disposed above the carrying device and is lifted by the carrying device for moving. In addition, the embodiment of the present invention further exemplarily provides a schematic view of a cargo container shown in fig. 3 in a positive state, and fig. 3 illustrates that the cargo container and the handling device are both located in a runway L1, and the cargo container does not encroach on the space of the remaining runways, such as a runway L2, a runway L3, and the like; accordingly, the embodiment of the present invention further exemplarily provides a schematic diagram of a loading container in a tilted state as shown in fig. 4, where fig. 4 illustrates that a carrying device is located in a runway L1, but the loading container encroaches on a runway L2 and a runway L3 due to deviation of a target direction of the loading container, and during operation of the carrying device in the runway L1, the loading container lifted by the carrying device is likely to collide with the loading container lifted by the carrying device operated in the runway L2 and the runway L3, so that a safety accident occurs.
In order to avoid the situation shown in fig. 4 as much as possible, an embodiment of the present invention provides a method for adjusting a storage container, which is shown in fig. 5, and the method mainly includes the following steps S502 to S506:
and step S502, acquiring the actual heading and the target heading of the carrying equipment.
In one embodiment, the carrying device can be provided with a positioning sensor for sensing the actual course of the carrying device, so that the actual course of the carrying device can be sensed in real time by the positioning sensor. The target heading of the handling equipment is a moving direction which the handling equipment should theoretically follow, and can also be understood as a task track direction or a direction of a runway on which the handling equipment is located.
In step S504, an angular deviation between the target direction of the container and the actual heading of the handling apparatus is obtained.
The target direction of the cargo container may be, for example, a direction perpendicular to a front surface of the cargo container or a direction perpendicular to a side surface of the cargo container, but the present invention is not limited thereto. The following description will be given taking an example in which the storage container is a shelf and the target direction is a direction perpendicular to the front surface of the shelf, and a direction perpendicular to the front surface of the shelf is a target direction of the shelf (this can be understood with reference to fig. 3 and 4). In addition, the angular deviation can be understood as the relative course between the container and the handling device, and if the target direction of the container is consistent with the actual course of the handling device, there is no angular deviation, i.e. the angular deviation is 0. If the target direction of the container is not consistent with the actual course of the carrying device, an angle deviation exists at the moment, and the angle deviation can be obtained by calculating the difference between the target direction of the container and the actual course of the carrying device.
Step S506, based on the actual course, the target course and the angle deviation, the direction of the goods container is adjusted until the target direction of the goods container is consistent with the target course of the carrying equipment.
In order to adjust the direction of the loading container to be consistent with the target course (runway direction) of the carrying equipment, course deviation between the actual course and the target course in the carrying equipment and angle deviation between the target direction of the loading container and the actual course of the carrying equipment need to be considered comprehensively.
The adjusting method of the goods placing container provided by the embodiment of the invention can finally adjust the target direction of the goods placing container to be consistent with the target course of the carrying equipment, thereby avoiding the problems that the target direction of the goods placing container deviates from the track (target course) where the carrying equipment should operate and the goods placing containers driven by different robots are easy to collide and the like in the process of driving the goods placing container by the carrying equipment, and effectively ensuring the transportation safety of the carrying equipment.
The carrying equipment provided by the embodiment of the invention can be provided with a positioning sensor, an angle sensor and a main control module, wherein the positioning sensor is used for sensing the actual course of the carrying equipment in real time, the angle sensor is used for detecting the target direction of the goods container, and the control module is used for controlling the carrying equipment and the goods container to rotate, such as the main control module of an AGV robot.
To facilitate understanding of the step S502, an embodiment of the present invention provides a specific implementation manner for obtaining an actual heading and a target heading of a transportation device, where the actual heading of the transportation device is detected by a positioning sensor on the transportation device, then a task to be executed by the transportation device is obtained, and the target heading of the transportation device is determined based on the task to be executed.
The Positioning sensor may include a sensor applying a Positioning technology such as an inertial navigation technology or a GPS (Global Positioning System) technology, for sensing an actual heading of the handling apparatus in real time. In one embodiment, the actual or target course of the handling device may be characterized on the basis of an angle, for example, a first coordinate system is pre-established on the basis of the actual site, which may be understood as a map coordinate system of the handling device relative to the application site, and the Y direction in the first coordinate system is used for characterizing the actual course of the handling device, see fig. 6a for a schematic diagram of the handling device relative to the first coordinate system, XtIs the horizontal axis of the first coordinate system, YtIs the longitudinal axis of the first coordinate system, YbFor the actual course of the handling equipment, XbAnd YbVertical, when the actual course Y of the handling equipmentbY relative to the first coordinate systemtWhen the axis is deviated to the right, YbAnd the extension line of the first coordinate system YtFirst angle theta between the axesbIs positive; referring to FIG. 6b, another schematic diagram of the handling device relative to the first coordinate system when the actual heading Y of the handling device is shownbY relative to the first coordinate systemtWhen the axis is deviated to the left, YbAnd the extension line of the first coordinate system YtFirst angle theta between the axesbIs negative, wherein the first included angle thetabCan be used to characterize the actual heading of the handling apparatus. It should be noted that the above is only one way of setting the coordinate system, and should not be considered as a limitation, such as the first included angle θ of fig. 6a may also be usedbSet to negative, first angle theta of fig. 6bbSet to positive.
In addition, the target course of the carrying equipment is determined based on the task to be executed, and the target course of the carrying equipment is determined based on the target track corresponding to the task to be executed, the target track can be obtained by planning based on a runway through a path control algorithm built in the carrying equipment, and the target track is consistent with the runway, so that the target course of the carrying equipment at each moment is determined according to the target track, and the carrying equipment moves along the runway based on the target course.
In order to obtain a target direction of a storage container, a direction identifier for indicating the target direction of the storage container is arranged on the storage container provided by the embodiment of the invention, wherein the direction identifier may include a one-dimensional code or a two-dimensional code with directionality, and the direction identifier is a two-dimensional code for example. Based on this, the embodiment of the present invention provides an implementation manner for obtaining an angle deviation between a target direction of a container and an actual heading of a handling device, which may be specifically referred to as the following steps a to b:
and a, determining the target direction of the goods container according to the direction identifier. In one embodiment, the carrying device may further be provided with a camera, and the camera may be used to capture an orientation indicator provided on the cargo container, so that the carrying device can recognize an image containing the orientation indicator, thereby determining the target orientation of the cargo container. If the carrying equipment provided by the embodiment of the invention is used for driving the goods placing container to move in a jacking mode, and the direction mark is attached to the bottom of the goods placing container, the logistics machine can identify the target direction of the goods placing container based on the direction mark at the bottom of the goods placing container.
And b, calculating the angle deviation between the target direction of the goods container and the actual course of the carrying equipment. In one embodiment, the angular deviation between the target direction of the container and the actual heading of the handling device may be characterized based on an angle, for example, a second coordinate system may be pre-established based on actual demand, which may be understood as a coordinate system of the container relative to the handling device, see fig. 7a for a schematic diagram of the handling device relative to the second coordinate system, XsIs the horizontal axis of the second coordinate system, YsIs the longitudinal axis of the second coordinate system, YsCan be used to characterize the target direction, Y, of the storage containerbCan be used for representing the actual course X of the handling equipmentbAnd YbVertical, when the actual course Y of the handling equipmentbY relative to a second coordinate systemsWhen the axis is deviated to the right, YbAnd the extension line second coordinate system YsSecond angle theta between the axessIs negative; referring to FIG. 7b, another schematic diagram of the handling apparatus relative to the second coordinate system is shown, when the actual heading Y of the handling apparatus isbY relative to the first coordinate systemsWhen the axis is deviated to the left, YbAnd the extension line of the first coordinate system YsSecond angle theta between the axessIs positive, wherein the second included angle thetasCan be used to characterize the angular deviation described above. It should be noted that the above is only one way of setting the coordinate system, and should not be considered as a limitation, such as the first angle of fig. 7a may also be usedθsSet to positive, first included angle θ of FIG. 7bsSet to negative.
After the actual heading and the target heading of the transporting device and the angular deviation between the target direction of the container and the actual heading of the transporting device are obtained according to the method provided by the embodiment, the direction of the container can be adjusted based on the actual heading, the target heading and the angular deviation, and in a specific implementation, the direction of the container can be adjusted according to the following steps 1 to 3:
and step 1, estimating the theoretical rotation angle of the carrying equipment according to the actual course and the target course. The theoretical rotation angle can be understood as an angle that the carrying device needs to rotate at the next moment when the carrying device is adjusted from the actual heading to the target heading. In one embodiment, the theoretical rotation angle θb1The theoretical rotation angle theta of the carrying equipment can be calculated and obtained through a path control algorithm in a control module of the carrying equipment, and optionally, the theoretical rotation angle theta of the carrying equipment can be calculated and obtained through the path control algorithm based on the motor performance of the carrying equipment and a target pathb1。
And 2, calculating a correction angle required when the target direction of the cargo container is adjusted to be consistent with the target course of the carrying equipment according to the actual course, the target course, the theoretical rotation angle and the angle deviation. In one embodiment, the calculation of the correction angle is described by taking the cases shown in fig. 6a and 7a as an example, and the correction angle θ can be calculated according to the following formulap：
θp＝SIGN(θs-θb1)*(θb+θs-θt-θt)；
Wherein, thetabRepresenting the actual heading, thetatRepresenting target heading, θsIndicating the angular deviation, thetab1Representing a theoretical rotation angle; when the angle deviation thetasGreater than or equal to the theoretical rotation angle thetab1Then, SIGN (θ)s-θb1) When the angular deviation theta is 1sLess than the theoretical angle of rotation thetab1Then, SIGN (θ)s-θb1) Is-1. The above formula is trueThe actual heading, the target heading, the angular deviation and the plus-minus situation of the theoretical rotation angle are related to respective positive and negative situations, and can be determined by the first coordinate system and the second coordinate system, which are just one example of the coordinate system and the positive and negative angles specified in fig. 6a and 7 a. In practical application, when the included angle between the actual heading of the carrying device and the target heading is known and the angle deviation between the actual heading of the carrying device and the target direction of the cargo container is known, the included angle (i.e., the correction angle) between the target direction of the cargo container and the target heading of the carrying device can be obtained based on the included angle between the actual heading of the carrying device and the target heading and the angle deviation between the actual heading of the target robot and the target direction of the cargo container.
And step 3, adjusting the direction of the goods container based on the corrected angle. In one embodiment, the motor of the conveying device may be adjusted to rotate based on the determined correction angle to drive the cargo container to rotate, so as to adjust the target direction of the cargo container to be consistent with the target heading of the conveying device. In addition, considering that the transportation equipment may have abnormal sensor detection in some cases, which may cause erroneous sensing detection results, and thus the final correction angle is too large, which may cause deviation in the direction adjustment of the cargo container, an embodiment of the present invention exemplarily provides an implementation manner for adjusting the direction of the cargo container based on the correction angle, and refer to the following steps 3.1 to 3.3:
and 3.1, judging whether the correction angle is larger than a preset angle threshold value. The preset angle threshold value can be set based on the performance of the conveying equipment and the task track of the conveying equipment. In one embodiment, the correction angle θ can be calculated in real time by a control module of the handling apparatuspAnd a preset angle threshold value thetalimitThe magnitude of which is compared.
And 3.2, when the correction angle is smaller than or equal to a preset angle threshold value, adjusting the direction of the goods container according to the correction angle. When correcting the angle thetapLess than or equal to a predetermined angle threshold thetalimitWhile, can be according to the correction angle thetapAnd controlling the carrying equipment to adjust the angle of the goods placing container so as to adjust the target direction of the goods placing container to be consistent with the target course of the carrying equipment.
And 3.3, when the correction angle is larger than a preset angle threshold, adjusting the direction of the goods container according to the preset angle threshold. When correcting the angle thetapGreater than a predetermined angle threshold thetalimitWill utilize a preset angle threshold thetalimitThe direction of the container is adjusted to avoid the abnormal adjustment result of the direction of the container due to the overlarge correction angle.
In one embodiment, when the correction angle is larger than a preset angle threshold value, recording that an angle abnormality occurs once; and when the occurrence frequency of the recorded angle abnormal phenomenon is greater than a preset frequency threshold value, initiating an alarm prompt. That is, if the angle abnormality occurs many times, it may be caused by an abnormality in a software program of the transportation device or an abnormality in a hardware device, and therefore, related personnel are required to perform maintenance processing on the transportation device in time. For example, the preset number threshold is 3, and when the correction angle is detected to be greater than the preset angle threshold for 4 times, an alarm prompt may be initiated, where the alarm prompt may include an audible alarm or a light alarm. In addition, an alarm prompt can be sent to the appointed related terminal, and related personnel of the related terminal are prompted to overhaul the carrying equipment.
In addition, because the actual course of the carrying equipment may deviate from the target course of the carrying equipment in the operation process of the carrying equipment, in order to correct the actual course of the carrying equipment in time, the embodiment of the invention also provides an implementation mode for adjusting the actual course of the carrying equipment, and particularly, the actual course of the carrying equipment can be adjusted based on the theoretical rotating angle of the carrying equipment so as to enable the actual course of the carrying equipment to be consistent with the target course.
