Description

Technical Field

[0001] The present invention relates to the technical field of material management, and in particular to a material life cycle tracing system and method based on smart labels. Background Art

[0002] With the rapid development of Internet of Things technology, the demand for full life cycle traceability of materials in the field of material management is increasing. Traditional material management methods have problems such as low traceability efficiency, inaccurate information, and difficulty in management (for example, the workload of manual inventory and data entry is large, goods are lost or misplaced, and it is difficult to inventory a large number of items in large warehouses). The full tracking and precise management of materials has important practical application value.

[0003] The invention patent with application number: 202111048719.9 discloses a material quality traceability method and system based on industrial Internet identification and blockchain. The method includes: constructing a unique identification code for materials according to industry identification coding specifications; obtaining material technical specification data, and registering identification according to the unique identification code of the materials, and constructing identification mapping data corresponding to each identification according to the technical requirement parameter name, upper limit and lower limit; uploading the identification, identification mapping data and hash value of the identification mapping data to the blockchain; performing the above-mentioned chain-up process on material production monitoring data and material quality inspection data in turn; cross-verifying the identification mapping data according to material technical specification data, material production monitoring data and material quality inspection data; and verifying the results and querying the cross-verification results through the blockchain according to the unique identification code of the materials. Compared with the prior art, the above invention realizes comprehensive, intuitive and transparent traceability of material quality, and improves the efficiency and security of data circulation.

[0085] In one embodiment, the encoding module includes:

[0086] The material type acquisition submodule is used to acquire the material type of the first target material; wherein the material type is: the material variety of the first target material, such as: tires;

[0087] The first coding bit code determination submodule is used to determine the first coding bit code according to the material type and the first coding bit determination library; wherein the first coding bit determination library includes: a plurality of one-to-one corresponding pre-selected material types and corresponding codes, for example: "tire" corresponds to "K";

[0095] In one embodiment, the traceability requirement information acquisition subsystem includes:

[0096] A management information determination module is used to parse the material code of the second target material and determine the management information of the second target material; wherein the management information is: management process information of the second target material;

[0097] The traceability template information determination module is used to determine the traceability template information according to the current time and the management information of the second target material. When determining the traceability template information according to the current time and the management information, the management process node in the management information is located according to the current time, and the specification information corresponding to the management process node is used as the traceability template information.

[0098] The working principle and beneficial effects of the above technical solution are:

[0099] The present invention determines the traceability template information for subsequent traceability comparison according to the current time and the management information of the second target material obtained by parsing the material code, which is more reasonable.

[0100] In one embodiment, the tracing result determination subsystem includes:

[0103] The tracking result determination module is used to determine the tracking result according to the tracking information and the traceability template information. When determining the tracking result according to the tracking information and the traceability template information, the standard information corresponding to the tracking information in the traceability template information is determined and the information is compared to determine the tracking result. For example, if the incoming RFID result of warehouse A at time T does not identify the RFID ID of part B, and the standard information in the traceability template information is: the incoming RFID result of warehouse A at time T should identify the RFID ID of part B, then the tracking result is: part B is lost at time T.

[0104] The working principle and beneficial effects of the above technical solution are:

[0105] The present invention determines the target entry node of the identification party that performs radio frequency tag identification of the target entry node most recently at the current moment, obtains tracking information of the second target material through the target entry node, compares the tracking information with corresponding standard information in the traceability template information to determine the tracking result, and tracks the materials more timely.

[0106] In one embodiment, the tracking information acquisition module includes:

[0107] The node type acquisition submodule is used to acquire the node type of the target entry node; the node types include: manual entry node and machine entry node; wherein the manual entry node is: the communication node of the manager who performs radio frequency tag scanning; the machine entry node is: the communication node of the scanning robot that performs radio frequency tag scanning;

[0109] The second tracking information determination submodule is used to obtain the second scanning information of the radio frequency scanning robot when the node type is a machine input node, and obtain the tracking information according to the second scanning information. The radio frequency scanning robot is: an intelligent robot equipped with an RFID identification device; the second scanning information is: the radio frequency signal identification result of the radio frequency scanning robot.

[0110] The working principle and beneficial effects of the above technical solution are:

[0111] This application introduces two ways to obtain tracking information. The first way is to obtain tracking information based on the first scanning information entered manually; the second way is to obtain tracking information based on the second scanning information entered by the robot. Introducing two ways to identify tag information is more comprehensive and intelligent.

[0112] In one embodiment, the tracking information second determination submodule includes:

[0113] The transport arrival status information acquisition unit is used to acquire the transport arrival status information of the second target material arriving at the management area corresponding to the target entry node; wherein the management area corresponding to the target entry node is: the material storage area after the second target material is completed at the target entry node; the transport arrival status information is: the video data before the second target material is entered at the target entry node;

[0114] A distribution determination unit is used to determine the distribution of the second target material according to the transport arrival status information; wherein the distribution of the second target material is: the point distribution of the second target material on the transport device;

[0115] A first distance calculation unit is used to calculate the first distance between the second target materials according to the distribution situation; wherein the first distance is: the distance between two of the second target materials;

[0116] A distributed material cluster determination unit, configured to treat the corresponding second target materials as a distributed material cluster if the first distance between the second target materials is less than or equal to a preset first distance threshold; wherein the first distance threshold is manually preset, such as 0.9 m;

[0117] The robot dispatching unit is used to dispatch the radio frequency scanning robot to the distributed material cluster for data entry. The distributed material cluster is: the position corresponding to the average position coordinate of the second target material in the distributed material cluster.

[0118] The working principle and beneficial effects of the above technical solution are:

[0119] During the life cycle of materials, there is a possibility of loss when materials are transferred from one location to another. Therefore, when the second target material arrives at the management area corresponding to the target entry node, it is necessary to enter information, check for missing materials, and pick up the second target material on the transport device through an automated RF scanning robot. Since the second target material may be in large quantity, it is necessary to coordinate the scheduling of RF scanning robots to determine the distribution of the second target materials based on the video data before the second target material is entered into the target entry node. Distance measurement is performed based on the distribution to determine the first distance between the second target materials. When the first distance is less than or equal to the first distance threshold, the corresponding second target material is divided into a distributed material cluster, and the RF scanning robots are dispatched to the distributed material clusters to perform material entry operations, so that the information entry of stored materials is automated and more intelligent.

[0120] In one embodiment, the robot scheduling unit comprises:

[0121] The first cluster number acquisition subunit is used to acquire the first cluster number of the distributed material cluster; wherein the first cluster number is: the number of clusters of the distributed material cluster;

[0122] The first robot number acquisition subunit is used to acquire the first robot number of idle radio frequency scanning robots; wherein the first robot number is: the idle radio frequency scanning robots in the management area when the second target material arrives at the management area;

[0123] A first allocation subunit is configured to allocate at least one radio frequency scanning robot to each distributed material cluster for data entry if the number of the first clusters is less than or equal to the number of the first robots; wherein when at least one radio frequency scanning robot is allocated to each distributed material cluster for data entry, the nearest radio frequency scanning robot corresponding to each distributed material cluster is determined as the allocated robot;

[0124] A first target radio frequency scanning robot determination subunit is used to determine the radio frequency scanning robot closest to the distributed material cluster if the number of the first clusters is greater than the number of the first robots, and use the radio frequency scanning robot as the first target radio frequency scanning robot of the corresponding distributed material cluster;

[0125] The number determination subunit is used to determine whether the number of the second robots of the first target radio frequency scanning robot is consistent with the number of the first robots; wherein the number of the second robots is: the number of the robots of the first target radio frequency scanning robot;

[0126] A second allocation subunit is used to dispatch the first target radio frequency scanning robot to go to the corresponding distributed material cluster to perform input operation if the number of the second robots is consistent with the number of the first robots;

[0127] A second cluster number calculation subunit, configured to obtain a second cluster number of the distributed material cluster corresponding to the first target radio frequency scanning robot if the second robot number is inconsistent with the first robot number;

[0128] A third allocation subunit is used to dispatch the corresponding first target radio frequency scanning robot to the distributed material cluster for input operation if the number of the second clusters is equal to 1;

[0129] a second target radio frequency scanning robot determining subunit, configured to use the first target radio frequency scanning robot as the second target radio frequency scanning robot if the number of the second clusters is greater than 1;

[0130] A target distributed material cluster determination subunit is used to take the distributed material cluster corresponding to the second target radio frequency scanning robot as the target distributed material cluster;

[0131] A fourth allocation subunit is used to obtain a second distance between each target distributed material cluster and the corresponding second target radio frequency scanning robot, associate the target distributed material cluster with the smallest second distance with the second target radio frequency scanning robot, and dispatch the second target radio frequency scanning robot to the associated target distributed material cluster to perform input operations;

[0132] A third target radio frequency scanning robot determination subunit is used to determine the remaining radio frequency scanning robots except the first target radio frequency scanning robot among the idle radio frequency scanning robots and use them as the third target radio frequency scanning robots;

[0133] The remaining distributed material cluster determination subunit is used to obtain the target distributed material clusters other than the target distributed material clusters associated with the second target radio frequency scanning robot, and use them as the remaining distributed material clusters;

[0134] The fifth allocation subunit is used to perform scanning operations on the remaining distributed material clusters according to the idle radio frequency scanning robots and the third target radio frequency scanning robots determined in real time.

[0135] The working principle and beneficial effects of the above technical solution are:

[0136] When dispatching RF scanning robots to distributed material clusters for data entry, there are many situations, such as: there are a large number of idle RF scanning robots, and each distributed material cluster can find a corresponding RF scanning robot for data entry; another example: there are a small number of idle RF scanning robots, and it is necessary to first enter data for some distributed material clusters, and then enter data for some distributed material clusters. Therefore, the first cluster number of distributed material clusters is compared with the first robot number of idle RF scanning robots. When the first cluster number is less than or equal to the first robot number, it means that each distributed material cluster can be assigned to at least one RF scanning robot; when the first cluster number is greater than the first robot number, relay data entry is required.

[0137] When relaying data entry, first determine the first target RF scanning robot closest to each distributed material cluster. Since the number of robots is less than the number of distributed material clusters, at least one first target RF scanning robot corresponds to more than one distributed material cluster. Obtain the number of second robots of the first target RF scanning robot, and determine whether the number of second robots of the first target RF scanning robot is consistent with the number of first robots, so as to measure whether each target RF scanning robot participates in the data entry operation. If they are consistent, it means that all RF scanning robots participate in the data entry operation, and dispatch the first target RF scanning robot to the corresponding distributed material cluster for data entry. The correspondence here means that the distance between the distributed material cluster and the first target RF scanning robot is greater than the distance with other RF scanning robots. If there is inconsistency, it means that the RF scanning robot resources are not allocated reasonably. The second cluster number of the distributed material cluster corresponding to the first target RF scanning robot is obtained. If the second cluster number is equal to 1, it means that the first target RF scanning robot corresponds to entering a distributed material cluster. The first target RF scanning robot is dispatched to that distributed material cluster to perform the entry operation. If the second cluster number is greater than 1, it means that the second target RF scanning robot corresponds to multiple distributed material clusters. The second distance between the target distributed material cluster and the corresponding second target RF scanning robot is calculated, and the target distributed material cluster with the smallest second distance is associated with the second target RF scanning robot and the second target RF scanning robot is dispatched to enter. The third target RF scanning robot with the remaining unassigned tasks is dispatched to the remaining distributed material clusters in the target distributed material cluster to perform scanning operations, thereby improving the work efficiency of automated scanning operations.

[0138] In one embodiment, the robot scheduling unit further includes:

[0139] The smart tag signal penetration feature determination subunit is used to determine the smart tag signal penetration feature when the RF scanning robot arrives at the distributed material cluster; wherein the smart tag signal penetration feature is: the identified RF signal emission point and the material code corresponding to the RF signal;

[0140] The first input subunit is used to input the second target material according to the smart tag signal penetration feature; wherein inputting the second target material according to the smart tag signal penetration feature includes: inputting the material code corresponding to the radio frequency signal;

[0141] The recorded material determination subunit is used to determine the second target material that has been currently recorded by the radio frequency scanning robot;

[0142] The second input subunit is used to control the mechanical arm preset on the radio frequency scanning robot to pick up the second target materials that have been input, and after picking up, continue to input the remaining second target materials until all the second target materials on site are input. When picking up the second target materials that have been input, the second target materials that have been input are determined according to the emission point of the radio frequency signal and the mechanical arm is controlled to take them, and continuing to input the remaining second target materials means continuing radio frequency identification and picking up until there is no second target material left at the distributed material cluster.

[0143] The working principle and beneficial effects of the above technical solution are:

[0144] The present invention introduces a smart tag signal penetration feature, and enters the second target material according to the smart tag signal penetration feature and controls the robotic arm to pick up the second target material that has been entered. After picking up, the remaining second target materials continue to be entered until all the second target materials on site are entered. The second target materials are identified in batches, which improves the entry efficiency. The secondary verification and identification of radio frequency identification also avoids the omission of second target materials caused by inaccurate radio frequency signal identification due to obstructions such as packaging.

[0145] The embodiment of the present invention provides a material life cycle tracing method based on smart labels, such as Figure 2 As shown, including:
