Description

Technical Field

[0001] The present invention relates to the technical field of warehouse management, and in particular to a warehouse management method based on a cloud platform. Background Art

[0002] Cable is the main equipment for power transmission and information transmission. With the continuous development of our society, there are more and more lines for information transmission and power transmission in our country. At present, the main method for storing cables is to coil the cables on drums and take a series of protective measures to protect them. Finally, the packaged cables are stacked in the warehouse. In the process of putting cables into storage, most of them are manually counted to complete the storage records. However, since the cables are coiled on drums and protectively packaged, the existing technology will waste a lot of time and test samples when verifying the quality of the cables. The existing technology cannot verify the incoming cables one by one, and cannot trace the links where problems occur. Moreover, the existing technology cannot timely schedule the storage location of the cables according to the changes in the storage environment. In addition, due to the many factors that affect the amount of cables in actual use, the existing technology cannot accurately calculate the actual amount of cables. Therefore, it is necessary to design a cloud platform-based storage management method to improve the accuracy of cable detection and improve the safety of goods. Summary of the invention

[0005] According to the above technical solution, the cargo inspection module includes a cargo detection module, which includes a physical feature detection module and an electrical feature detection submodule. The physical feature detection module is used to detect whether the appearance, size, and structure of the cable are damaged, and the electrical feature detection submodule is used to detect the conductivity and resistance value of the cable core;

The usage management module is used to plan the usage according to the drawings of the implementation project and to review the compensation requests for the cable usage. The quality traceability module is used to query the usage records of the cables.

[0008] According to the above technical solution, the usage management module includes a usage calculation submodule and an authority management submodule. The usage calculation submodule is used to calculate the usage of cables required for the project according to the construction drawings, and to correct the usage according to the actual construction situation. The authority management submodule is used to verify the identity authority of the person who uses the cable lines.

[0009] According to the above technical solution, the information acquisition module includes a visual module, an ultrasonic module and an information entry module.

[0010] According to the above technical solution, the warehouse management method mainly includes the following steps:

[0011] Step S1: Enter the appearance visual image and cross-sectional data of the cable into the system through the visual module, transmit ultrasonic signals to the cable to be stored through the ultrasonic module, receive feedback of the ultrasonic signals, and enter the model data and comprehensive parameters of the cable to be stored into the system through the information entry module;

[0012] Step S2: When the cables are put into storage, the system triggers the cargo detection module through an electrical signal to start analyzing the physical and electrical characteristics of the cables and matching the cargo according to the analysis results;

[0013] Step S3: When cables are required to be taken from the warehouse due to construction, the system starts the usage management module, starts to analyze the engineering circuit drawings and actual construction conditions, and calculates the length of cables required for the project based on the engineering drawings and actual construction conditions;

[0014] Step S4: When the cable is shipped out of the warehouse and shipped in, the system saves the shipping record and usage record of the cable to the database through the cargo record module, and traces the usage record of the cable through the quality traceability module.

[0015] According to the above technical solution, step S2 further includes the following steps:

[0016] Step S21: retrieve the cross-sectional visual image of the cable, scan and identify the conductor area in the cross-sectional area of ​​the cable, anchor the edge of the conductor area, identify the edge feature nodes of the conductor, connect the contour feature nodes of the conductor, build a conductor cross-sectional profile model, measure the diameter of a single conductor and the number of conductor wires in the conductor cross-sectional model, compare the comprehensive parameters of the cable entered into the database, if the diameter of a single conductor in the current cable has an error greater than a threshold value with the parameter in the database, then mark the current cable as having a problem, if there is a difference between the number of conductor wires in the current cable and the comprehensive parameters of the cable, then mark the current cable as having a problem, otherwise mark the current cable as having a preliminary certification;

[0017] Step S22: retrieve the visual image of the cable when it is coiled on the reel, grayscale the visual image, identify the RGB color value in the processed image, if there are pixels on the cable whose RGB color value is greater than the threshold set by the system, connect the pixels in pairs to construct the problem area, and mark the problem area as scratches or stains, retrieve the ultrasonic detection data of the cable, build a cable model based on the ultrasonic detection data, identify the structure in the cable model, and compare the cable model in the database. If there is a difference between the constructed cable model and the cable model in the database, mark the difference in the cable model and refuse to enter the warehouse. Otherwise, mark it as the second certified cable;

[0018] Step S23: retrieve the length of the current cable, the material of the conductor, the cross-sectional diameter of an independent wire in the current cable, and the number of independent wires in the current cable, and further calculate the resistance value of the current cable.

[0019] According to the above technical solution, step S23 further includes the following steps:

[0020] Step S231: According to the conductor material of the current cable, retrieve the resistivity of the material and calculate the resistance value of the current cable using the formula In the formula, i=1,2,3......n, R represents the resistance value of the current cable, L represents the total length of the current cable, ρ represents the resistivity of the conductor material in the current cable, κ represents the influence coefficient of the current conductor density on the resistance value, and S represents the area of ​​an independent wire cross section in the current cable. If the resistivity value is greater than the minimum threshold set by the system, the current cable is marked as a problematic cable, otherwise it is marked as a third certification cable.

[0021] Step S232: retrieve the cable lines to be put into storage, identify the certification marks on the current cable lines, if the current cable lines have preliminary certification, second certification and third certification marks, then identify the comprehensive parameters and names of the cable lines in the cable line marks, compare the cable line names and comprehensive parameters in the incoming bill of lading, identify the current cable line name and the placement of the cable lines under the corresponding comprehensive parameters, clear all labels on the current cable line, mark the name, comprehensive parameters and placement of the current cable line, and record and save the data of the incoming cable lines through the cargo record module, otherwise the current cable line will be refused to enter storage.

[0022] According to the above technical solution, step S3 further includes the following steps:

[0023] Step S31: retrieve the current engineering circuit drawing, build a construction circuit model according to the current factory circuit drawing, identify the circuit inflection point in the construction circuit model, measure the angle θ of the circuit inflection point, if the inflection point angle θ is greater than the threshold set by the system, then calculate the number of inflection points in the construction circuit model whose inflection point angle θ is greater than the threshold set by the system, and calculate the cable length required for the inflection point by the formula Where, i = 1, 2, 3...n, L1 represents the cable length required for the inflection point whose inflection point angle is greater than the system set threshold, θ represents the angle of the inflection point, π represents the pi, r represents the radius of the circle enclosed by the inflection point, and λ represents the influence coefficient of the inflection point angle on the required cable length;

[0024] Step S32: If the inflection point angle θ is less than or equal to the threshold, the length required for the inflection point is a fixed value L2. If the two circuits are parallel and the distance is less than the system set threshold, the cable length required for the corner is calculated according to the formula In the formula, j = 1, 2, 3 ... m, L3 represents the cable length required when two circuits are parallel and the distance is less than the system set threshold, d represents the distance between the two lines, and the total required cable length is calculated by the formula Wherein, k = 1, 2, 3 ... n, q = 1, 2, 3 ... n, L4 represents the cable length required for the straight line circuit of the current project, and L5 represents the cable length reserved for the current project;

[0025] Step S33: When there are not enough cables, the construction person in charge will inject the circuit drawings of the cables that have not yet been laid into the compensation request and enter the information into the module system to identify the authority identifier and the compensation cable length in the compensation request, and compare them with the authority identifier library in the system. When the authority level in the compensation request is the first authority, the compensation request is agreed, and an equal amount of cable length is retrieved for compensation. When the authority level in the compensation request is the second authority, the compensation cable length in the compensation request is further retrieved. If the compensation cable length is greater than the threshold set by the system, the system identifies the department to which the current person in charge belongs, retrieves the virtual phone number of the current department head, and inquires through the virtual phone whether the compensation request is agreed. Otherwise, the compensation request is directly agreed.

[0026] According to the above technical solution, in step S33, when the cable is put into storage, the inspection data of the cable is retrieved, and the comprehensive inspection data of the cable is imported into the label of the cable. When the cable is put into use, the calculated cable usage length, time, using department and consignee are retrieved, and the cable length, time, using department and consignee are recorded and stored in the database. When the compensation application is agreed to be issued, the total length of the cable used by the current department is retrieved. If the total length of the cable is greater than the system set threshold at this time, the current compensation request is interrupted, and the current department usage record is retrieved, packaged and sent to the regulatory department. Otherwise, the cable continues to be issued. The regulatory department retrieves all usage records of the current cable through the quality traceability module and uses the cable usage records for investigation.

[0027] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention can quickly compare whether the current cable is qualified by detecting the conductor size in the cross section of the cable and whether the conductor meets the comprehensive parameters of the cable to be stored, thereby avoiding problems with the cable during use; by detecting scratches and stains on the surface of the cable and the internal structure of the cable, it can accurately find problems with the current cable and avoid problematic cables from entering the warehouse, thereby improving the accuracy of cable quality detection; by calculating the resistance value of the current cable, it can quickly detect problems with the current cable and avoid problematic cables from entering the warehouse, thereby further improving the detection efficiency of the system; by repeatedly detecting the comprehensive parameters of the current cable, It can prevent cables with quality problems from entering the warehouse, prevent problematic cables from being used in the factory, avoid potential safety hazards and safety accidents, and further improve the safety of cable management. The above formula can quickly obtain the total cable length required for the current project, which can save cable usage, reduce the investment in cable resources, and further reduce storage management losses. By reviewing the permissions in the cable application and contacting the superior person in charge through a virtual phone when the permissions are insufficient, it can avoid extension of the construction period due to insufficient materials, further reduce the construction period, further speed up factory construction, and reduce losses. The safety of the cable is further guaranteed by recording and saving all the in and out of the warehouse and use requests of the cable in the database. BRIEF DESCRIPTION OF THE DRAWINGS
