Description

Technical Field

[0001] The present invention belongs to the technical field of warehousing logistics vehicles, and relates to storage boxes, and in particular to an obliquely inserted logistics box capable of identifying a usage status, and a method for identifying the status thereof. Background Art

[0002] The oblique-insertion logistics box has a place in the logistics industry for its moisture-proof, durable, and easy-to-clean features. The oblique-insertion logistics box has a trapezoidal side, which allows it to be inserted into each other for stacking when empty, saving space and effectively saving transportation costs. It is now widely used in supermarkets, tobacco, pharmaceuticals and other industries. In order to further improve the recycling efficiency of oblique-insertion logistics boxes, it is necessary to accurately and quickly identify the use status of logistics boxes, so as to timely optimize the allocation plan of logistics boxes, increase the recovery and use speed of empty and full boxes, and reduce backlogs.

[0003] Under the current logistics box management model, the number and usage of logistics boxes are usually counted manually. However, the number of oblique-insertion logistics boxes is huge, which not only makes the counting slow, but also makes it difficult to ensure the accuracy of the counting. It is impossible to distinguish the usage status of all logistics boxes in time, and it is impossible to meet the company's demand for accurate allocation of oblique-insertion logistics boxes. In order not to affect normal production, companies are forced to increase the number of logistics boxes, but a large number of existing logistics boxes are idle. The increase in ineffective investment has brought huge cost pressure to companies.

[0004] In order to solve the problem of difficulty in inventorying obliquely inserted logistics boxes, existing studies have proposed adding pressure sensors, light sensors, magnetic field sensors, etc. inside the logistics boxes to identify the use status of the logistics boxes. However, the identification mechanism has some shortcomings:

[0005] 1. The pressure sensor needs to be placed inside the logistics box to determine whether the logistics box is loaded with goods by sensing the pressure change; an increase in pressure indicates that the goods are loaded; zero pressure indicates that the logistics box is empty. However, this method is likely to affect the appearance and hygiene of the goods due to direct contact, and repeated squeezing also poses certain challenges to the life of the sensor. Therefore, the use of pressure sensors is not universally applicable;

[0006] 2. The light sensor is configured to identify the detected light intensity, compare the light intensity change value and / or the light intensity change rate, and when it exceeds a given threshold, it indicates that the logistics box is in the corresponding state. This method has high requirements for setting the threshold. When empty boxes are stacked, the upper logistics box is inserted into the lower logistics box, which will also cause light changes, making it difficult to accurately distinguish it from the state of cargo loading;

[0007] 3. The magnetic field sensor relies on the change of the magnetic field inside the logistics box to judge the usage status of the logistics box. The disadvantage of this method is that it is greatly affected by the external environment. When there are many metal objects around the logistics box, it is easy to cause sensor failure.

[0008] In addition, sensors such as sound, deformation, and vibration also have similar defects when used for usage status identification. There is an urgent need to use a more accurate, efficient, and safer method for identifying the usage status of oblique-insertion logistics boxes. Summary of the invention

[0009] The purpose of the present invention is to overcome the deficiencies of the prior art and to propose an obliquely inserted logistics box capable of identifying the usage status and a method for identifying the status thereof, which can realize accurate, efficient and safe identification of the usage status of the obliquely inserted logistics box.

[0010] The present invention solves the technical problem by the following technical solutions:

[0011] A slanted-insert logistics box with identifiable usage status comprises a box body, a left box cover and a right box cover, the left and right sides of the box body are respectively hingedly connected to the left box cover and the right box cover, the end of the left box cover is alternately provided with male buckles and female buckles, the end of the right box cover is alternately provided with female buckles and male buckles corresponding to the left box cover, the male buckles and female buckles of the left box cover and the right box cover are snap-connected, the inner and outer sides of the left box cover and the right box cover are both provided with installation grooves, and a smart electronic tag is installed in any of the installation grooves.

[0012] Moreover, the smart electronic tag includes a battery, an angle sensor, an acceleration sensor and a mobile communication module. The angle sensor, acceleration sensor and mobile communication module are all connected to the battery, the angle sensor and acceleration sensor are respectively connected to the mobile communication module, and the mobile communication module is connected to an external cloud server through a base station.

[0013] Moreover, the smart electronic tag is mounted, riveted or bonded in the installation groove, and the upper surface of the smart electronic tag is lower than the surface of the left box cover or the right box cover.

[0014] Moreover, both ends of the left box cover and the right box cover are overlapped and provided with guide grooves, and the left box cover and the right box cover are hingedly connected to the box body along the guide grooves.

[0015] Moreover, fixing holes are arranged on the left box cover and the right box cover.

[0016] Moreover, wedge-shaped reinforcing ribs are provided at both ends of the left box cover and the right box cover.

[0017] Moreover, the sides of the box body are provided with reinforcing ribs.

[0018] Moreover, buckles are arranged on both sides of the box body.

[0019] Moreover, the box body has a structure that is wide at the top and narrow at the bottom.

[0020] A state identification method for an obliquely inserted logistics box capable of identifying a use state, wherein when the obliquely inserted logistics box is loaded with goods, the left box cover and the right box cover are in a closed state; when the obliquely inserted logistics box is in an empty state, the left box cover and the right box cover are in an outwardly opened and naturally drooping state;

[0021] The steps of the method are:

[0022] S1. Box cover posture recognition based on angle sensor

[0023] 1) According to the installation posture of the smart electronic tag, when the angle sensor measures that the flip angle of the smart electronic tag is close to 0°, it means that the left box cover and the right box cover are in a closed state, and it is judged that the oblique insertion logistics box is in a loading state at this time;

[0024] 2) When the angle sensor measures that the flip angle of the smart electronic tag is greater than 180°, it means that the left and right box covers are in a naturally drooping state after being opened, and it is judged that the oblique insertion logistics box is in an empty state at this time;

[0025] S2. Box cover posture recognition based on acceleration sensor

[0026] The smart electronic tag is a rectangular parallelepiped structure, and the three axes X, Y, and Z are used to represent the three axes perpendicular to the front, side, and top of the smart electronic tag respectively. The valid values ​​of the three axes are [-1, 1]. When the value is 0, it means that the axis is horizontal; when the value is 1, it means that the axis is in the same direction as the gravity acceleration and is vertically downward; when the value is -1, it means that the axis is in the opposite direction to the gravity acceleration and is vertically upward;

[0027] 1) When the absolute value of the Z axis is close to -1, and both the X and Y axes are close to 0, it means that the left and right lids of the obliquely inserted logistics box are in a closed state, and it is judged that the logistics box is loaded with cargo at this time;

[0028] 2) When the Z axis is close to 0, the absolute value of the Y axis is close to 1, and the X axis is close to 0, it means that the left and right covers of the oblique insertion logistics box are in a naturally hanging state after opening, and it is judged that the logistics box is empty at this time.

[0029] The advantages and beneficial effects of the present invention are:

[0030] 1. The invention is easy to install and has high reliability: the smart electronic tag can be fixed in the inner or outer groove of the flip cover of the logistics box by snapping, riveting, gluing, etc. It is easy to install, firm, and not easy to fall off. The smart electronic tag does not contact the goods and will not affect each other. Each oblique plug-in logistics box has an installation groove on the inside and outside of the left and right box covers, so there are 4 installation positions for users to flexibly choose.

[0031] 2. More accurate identification of the use status of obliquely inserted logistics boxes: Based on the intelligent electronic tag, the flip-up posture of the logistics box can be judged by flip-up angle and three-axis value, thereby judging the use status of the logistics box. This identification method does not require contact with the goods, and the judgment result is not affected by the storage environment of the logistics box and the type of goods, and has wide applicability.

[0032] 3. Effectively improve the turnover efficiency of oblique-insertion logistics boxes and reduce ineffective asset investment: The use status of oblique-insertion logistics boxes is uploaded to the cloud server in real time, and users can view the use status of all assets at any time, without manual inventory, saving human capital. The use status does not require manual inventory, saving human resources and improving inventory efficiency and accuracy. Combined with the real-time inventory data of logistics boxes, allocation plans can be made in time according to demand, so as to fully utilize assets, reduce ineffective investment, and effectively save costs for enterprises.
