[0051] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0052] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but unless otherwise specified, these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script.

[0053] like Figure 1 FIG. 1 is a flowchart of a warehouse material management method based on RFID provided by an embodiment of the present invention, wherein the method comprises:

[0054] S100, constructing a site model, and setting a plurality of marking reference points in the site model.

[0055] In this step, a site model is constructed. Specifically, the model is constructed according to the actual scale, such as modeling at a scale of 1:1. A three-dimensional site model is constructed. According to the stacking rules of the goods on site, corresponding marking reference points are set on site. Labels used separately for the marking reference points are set on the marking reference points, that is, each good has an independent label, and each marking reference point has an independent label. In order to improve the accuracy, the marking reference points are set close to the goods. For example, if a large number of goods are stacked somewhere on the site, a marking reference point is set next to the goods. Since the size and dimensions of the site are known, the positions of the marking reference points can be determined one by one by measuring the distances between the marking reference points. A three-dimensional coordinate system is constructed, and then the site model is imported into it to determine the coordinates of each point in the site model, including the coordinates of the marking reference points.

[0056] S200, obtaining reader movement data and reading data, dividing the reader movement data according to the time of performing a reading operation in the reading data, and obtaining independent movement data.

[0057] In this step, the reader movement data and reading data are obtained. In the process of modeling, a three-axis acceleration sensor is set on the reader. The acceleration of the reader in each direction can be known through the three-axis acceleration sensor. By integrating the acceleration curve, the movement speed of the reader in each direction can be calculated. Therefore, by collecting the acceleration data collected by the three-axis acceleration sensor, the movement path of the reader can be calculated based on it. The reading data is the data obtained when the reader reads the tag, which includes not only the information of the goods or the mark reference point, but also the time information of the reading operation. When reading, the mark reference point is used to obtain the time information of the goods or the mark reference point. The reader starts from the marking reference point, arrives at the goods, and then returns to the marking reference point. Specifically, first use the reader to read a marking reference point, then move the reader to the goods, use the reader to read the label on the goods, and then return to any marking reference point, preferably the last marking reference point read, to read its label. For example, A is the marking reference point and B is the goods, then the reader reads the label of A first, then the label of B, and then the label of A. At this time, the data collection of one goods is completed. Therefore, the reader movement data is divided according to the time of the reading operation in the reading data to obtain independent movement data. Each independent data corresponds to the reading process of this one goods.

[0058] S300, analyzing the independent movement data to determine the movement path between each tag and the corresponding marked reference point.

[0059] In this step, the independent mobile data is parsed. Since in one mobile data, there are corresponding moving paths for the two processes of the reader going to the cargo tag and leaving the cargo tag, the two moving paths are extracted to obtain the moving path between each tag and the corresponding marking reference point.

[0060] S400, marking the site model according to the moving path of each tag, and marking the location of each cargo in the site model.

[0061] In this step, the site model is marked according to the moving path of each tag. Since the moving path has been determined and the position of the marking reference point has been marked in the site model, the specific position of the tag can be calculated according to the moving path. The position of the tag represents the position of the goods, and each tag corresponds to two sets of moving paths, which means two positions are determined. A range area is determined based on the above two positions. The goods are within the range and can be marked. When looking for goods, the coordinate position of the goods can be directly derived by inputting the information of the goods, so that the management personnel can find the goods easily.

[0062] like Figure 2As shown, as a preferred embodiment of the present invention, the step of obtaining the reader movement data and the reading data, dividing the reader movement data according to the time of performing the reading operation in the reading data, and obtaining independent movement data specifically includes:

[0063] S201, obtaining reader movement data and reading data, and extracting the time axis of the reader movement data and reading data.

[0064] In this step, the reader movement data and reading data are obtained. In this process, the reader is moved to read each tag through the reader. In this process, the three-axis acceleration sensor on the reader is used to record data to obtain the reader movement data, and what the reader reads is the reading data. Regardless of reading the tag or moving the reader, the time information is recorded, that is, each data has a corresponding collection time, which is the time axis.

[0065] S202, identifying the time information corresponding to each reading operation in the reading data, determining the time between two adjacent readings of the marked reference points, and dividing the time axis.

[0066] In this step, the time information corresponding to each reading operation in the reading data is identified. In the process of using a reader to read a label, the time for reading each label is different because the reader needs to be moved. The reading data records the time of each label reading. Regardless of whether it is a cargo label or a label at a reference mark point, the corresponding reading time is recorded when reading. The time axis is divided into multiple intervals by the time when two adjacent labels on the marked reference points are read.

[0067] S203, dividing the reader movement data based on the time axis to obtain independent movement data, wherein the independent movement data includes three groups of reading operations, wherein targets corresponding to two reading operations are marked reference points.

[0068] In this step, the reader movement data is divided based on the time axis, and the corresponding reader movement data during this period is independent movement data, which includes the movement data of the reader moving from the mark reference point to the goods and the movement data from the goods back to the mark reference point.

[0069] like Figure 3 As shown, as a preferred embodiment of the present invention, the step of parsing the independent movement data to determine the movement path between each tag and the corresponding marking reference point specifically includes:

[0070] S301, analyzing the independent mobile data, and dividing it into incoming mobile data and outgoing mobile data.

[0071] In this step, the independent movement data is parsed. Since the independent movement data includes the movement data of the reader from the mark reference point to the goods and the movement data from the goods back to the mark reference point, it is split into two parts. Specifically, based on the time of reading the goods label, the independent movement data is divided into two parts, namely, the incoming movement data and the outgoing movement data. The incoming direction refers to the direction from the goods to the mark reference point, and the outgoing direction refers to the direction from the mark reference point to the goods.

[0072] S302, reversely process the incoming mobile data to obtain inverse mobile data.

[0073] S303, generating two groups of movement paths according to the inverse movement data and the destination movement data, wherein the movement paths are paths starting from the marked reference point and arriving at the corresponding tag.

[0074] In this step, the incoming movement data is reversely processed, that is, it is converted into the direction of movement from the marked reference point to the goods. For example, in the incoming movement data, the reader moves ten centimeters toward the goods, which is converted into the reader moving ten centimeters toward the marked reference point. This process is to read the data in reverse according to the actual movement process. For example, the incoming movement data moves from the goods to the marked reference point within 10 seconds, which is the moment of the 10th second when moving from moment 0 in chronological order. The reverse processing is to move from the moment of the tenth second to moment 0. When reading the data, read from the 10th second until moment 0 is read. At this time, the inverted movement data is obtained. The inverted movement data and the outgoing movement data record the direction and distance of movement.

[0075] like Figure 4 As shown, as a preferred embodiment of the present invention, the step of marking the site model according to the moving path of each tag and marking the position of each cargo in the site model specifically includes:

[0076] S401, reading the site model, and determining the coordinates of each marked reference point in the site model.

[0077] S402, determining the scale of the site model, and determining two corresponding end points according to the moving path of each tag.

[0078] In this step, the site model is read. Since the positions of each marked reference point have been determined and the site model is constructed at a 1:1 ratio, the coordinates of the marked reference point can be directly determined. The site model is constructed in a three-dimensional coordinate system, and the overall structure of the site model is determined by multiple coordinate points. In the site model, the positions of each marked reference point are determined, and the moving path determines the direction and distance of movement. Based on this, the end position corresponding to each moving path can be directly determined. Each tag has two sets of moving paths, which naturally produces two sets of end positions.

[0079] S403, generating an optional label range according to the two end positions, generating label end coordinates and determining the range area.

[0080] In this step, an optional label range is generated based on the two end positions, the midpoint of the line between the two end positions is used as the label end point, the label end point coordinates are generated, and a spherical range is determined with the distance between the two end positions as the radius. The spherical range can be regarded as the range where the goods are located, that is, the range area where the goods are located.

[0081] like Figure 5 As shown, an RFID-based warehouse material management system provided by an embodiment of the present invention includes:

[0082] The model marking module 100 is used to construct a site model and set a plurality of marking reference points in the site model.

[0083] In the present system, the model marking module 100 constructs a site model. Specifically, the model is modeled according to the actual proportion, such as modeling according to the proportion of 1:1, to construct a three-dimensional site model. According to the stacking rules of the goods on site, corresponding marking reference points are set on the site. Labels used separately for the marking reference points are set on the marking reference points, that is, each good has an independent label, and each marking reference point has an independent label. In order to improve the accuracy, the marking reference points are set close to the goods. For example, if a large number of goods are stacked somewhere on the site, a marking reference point is set next to the goods. Since the size and dimensions of the site are known, the positions of the marking reference points can be determined one by one by measuring the distances between the marking reference points, and a three-dimensional coordinate system can be constructed. Then, the site model is imported into it, and the coordinates of each point in the site model can be determined, including the coordinates of the marking reference points.

[0084] The data splitting module 200 is used to obtain the reader movement data and the reading data, and divide the reader movement data according to the time when the reading operation is performed in the reading data to obtain independent movement data.

[0085] In this system, the data splitting module 200 obtains the reader movement data and reading data. In the process of modeling, a three-axis acceleration sensor is set on the reader. The acceleration of the reader in various directions can be known through the three-axis acceleration sensor. By integrating the acceleration curve, the movement speed of the reader in various directions can be calculated. Therefore, by collecting the acceleration data collected by the three-axis acceleration sensor, the movement path of the reader can be calculated based on this. The reading data is the data obtained when the reader reads the label, which includes not only the information of the goods or the reference point of the mark, but also the time information of the reading operation. When reading, It starts from the marked reference point, arrives at the goods, and then returns to the marked reference point. Specifically, it first uses the reader to read a marked reference point, then moves the reader to the goods, uses the reader to read the label on the goods, and then returns to any marked reference point, preferably the last marked reference point read, to read its label. For example, A is the marked reference point and B is the goods, then the reader first reads the label of A, then reads the label of B, and then reads the label of A. At this time, the data collection of one goods is completed. Therefore, the reader movement data is divided according to the time of the reading operation in the reading data to obtain independent movement data. Each independent data corresponds to the reading process of this one goods.

[0086] The moving path generating module 300 is used to parse the independent moving data and determine the moving path between each tag and the corresponding marking reference point.

[0087] In this system, the mobile path generation module 300 parses the independent mobile data. Since in one mobile data, there are corresponding mobile paths for the two processes of the reader going to the cargo tag and leaving the cargo tag, the two mobile paths are extracted to obtain the mobile path between each tag and the corresponding marking reference point.

[0088] The tag position marking module 400 is used to mark the site model according to the moving path of each tag, and mark the position of each cargo in the site model.

[0089] In this system, the tag position marking module 400 marks the site model according to the moving path of each tag. Since the moving path has been determined and the position of the marking reference point has been marked in the site model, the specific position of the tag can be calculated according to the moving path. The position of the tag represents the position of the goods, and each tag corresponds to two sets of moving paths, which means two positions are determined. A range area is determined based on the above two positions. The goods are within the range and can be marked. When looking for goods, the coordinate position of the goods can be directly derived by inputting the information of the goods, so that the management personnel can find the goods easily.

[0090] like Figure 6 As shown, as a preferred embodiment of the present invention, the data splitting module 200 includes:

[0091] The data processing unit 201 is used to obtain the reader movement data and the reading data, and extract the time axis of the reader movement data and the reading data.

[0092] In this module, the data processing unit 201 obtains the reader movement data and reading data. During this process, the reader is moved to read each tag through the reader. During this process, the three-axis acceleration sensor on the reader is used to record data to obtain the reader movement data, and what the reader reads is the reading data. Regardless of reading the tag or moving the reader, the time information is recorded, that is, each data has a corresponding collection time, which is the time axis.

[0093] The time axis division unit 202 is used to identify the time information corresponding to each reading operation in the reading data, determine the time between two adjacent readings of the marked reference points, and divide the time axis.

[0094] In this module, the time axis division unit 202 identifies the time information corresponding to each reading operation in the reading data. In the process of using the reader to read the label, since the reader needs to be moved, the time for reading each label is different. The reading data records the time of each label reading. Regardless of whether it is a cargo label or a label at a reference mark point, the corresponding reading time is recorded when reading. The time axis is divided into multiple intervals based on the time when the labels on the marked reference points are read twice adjacently.

[0095] The data cutting unit 203 is used to divide the reader movement data based on the time axis to obtain independent movement data, wherein the independent movement data includes three groups of reading operations, wherein the targets corresponding to two reading operations are the marked reference points.

[0096] In this module, the data cutting unit 203 divides the reader movement data based on the time axis, and the corresponding reader movement data during this period is independent movement data, which includes the movement data of the reader moving from the marking reference point to the goods and the movement data from the goods back to the marking reference point.

[0097] like Figure 7 As shown, as a preferred embodiment of the present invention, the moving path generation module 300 includes:

[0098] The data parsing unit 301 is used to parse the independent mobile data and divide it into incoming mobile data and outgoing mobile data.

[0099] In this module, the data parsing unit 301 parses the independent movement data. Since the independent movement data includes the movement data of the reader from the mark reference point to the goods and the movement data from the goods back to the mark reference point, it is divided into two parts. Specifically, based on the time of reading the goods label, the independent movement data is divided into two parts, namely, the incoming movement data and the outgoing movement data. The incoming direction refers to the direction from the goods to the mark reference point, and the outgoing direction refers to the direction from the mark reference point to the goods.

[0100] The inverse processing unit 302 is used to perform inverse processing on the incoming mobile data to obtain inverse mobile data.

[0101] The path processing unit 303 is used to generate two groups of movement paths according to the inverse movement data and the destination movement data, wherein the movement paths are paths starting from the marked reference point and arriving at the corresponding tag.

[0102] In this module, the incoming movement data is processed in reverse, that is, it is converted into the direction of movement from the marked reference point to the goods. For example, in the incoming movement data, the reader moves ten centimeters toward the goods, which is converted into the reader moving ten centimeters toward the marked reference point. This process is to read the data in reverse according to the actual movement process. For example, the incoming movement data moves from the goods to the marked reference point within 10 seconds, which is the 10th second moment when moving from time 0 in chronological order. The reverse processing is to move from the 10th second moment to time 0. When reading the data, read from the 10th second until time 0 is read. At this time, the inverted movement data is obtained. The inverted movement data and the outgoing movement data record the direction and distance of movement.

[0103] like Figure 8 As shown, as a preferred embodiment of the present invention, the tag position marking module 400 includes:

[0104] The reference point marking unit 401 is used to read the site model and determine the coordinates of each marked reference point in the site model.

[0105] The end point position determination unit 402 is used to determine the scale of the site model and determine the corresponding two end point positions according to the moving path of each tag.

[0106] In this module, the site model is read. Since the position of each marked reference point has been determined and the site model is constructed at a 1:1 ratio, the coordinates of the marked reference points can be directly determined. This site model is constructed in a three-dimensional coordinate system, and the overall structure of the site model is determined by multiple coordinate points. In the site model, the position of each marked reference point is determined, and the moving path determines the direction and distance of movement. Based on this, the end point position corresponding to each moving path can be directly determined. Each tag has two sets of moving paths, which naturally produces two sets of end points.

[0107] The label area division unit 403 is used to generate a selectable label range according to the two end point positions, generate label end point coordinates and determine the range area.

[0108] In this module, the label area division unit 403 generates an optional label range according to the two end positions, takes the midpoint of the line between the two end positions as the label end point, generates the label end point coordinates, and determines a spherical range with the distance between the two end positions as the radius. The spherical range can be regarded as the range where the goods are located, that is, the range area where the goods are located.
