Description

Technical Field

[0001] The invention belongs to the technical field of warehouse management, and in particular relates to a welding wire warehouse personnel behavior management system. Background Art

[0002] Wire reel container warehouse is mainly used in welding fields such as shipyards and nuclear power equipment manufacturers, which require a large number of wire reels. In such fields, the material collector needs to collect one or more reels of welding wire every day. At present, warehouses generally store a variety of specifications of welding wire in batches, with large reserves and many varieties. The workload of manual sorting is extremely large. Most warehouses have a secondary welding wire warehouse. The warehouse manager will collect the welding materials to be used the next day from the primary welding wire warehouse according to the production plan for the next day, and store them in the secondary welding wire warehouse; when the material collector starts construction the next day, he can directly go to the welding wire warehouse to collect the welding materials he needs.

[0003] At the beginning of each day's work, the welding wire warehouse takes out the required welding materials from the welding wire warehouse according to the needs of each worker, and distributes them to the workers after the workers sign for them. Since each worker's welding station is far away from the welding wire warehouse, it takes relatively longer time for the material collector to collect the welding materials. It generally takes 1.5-2 hours from the beginning of distribution to the end of the last worker's collection. Manual distribution is more prone to problems such as wrong collection and misappropriation. The management and traceability of welding materials are very difficult. Generally, in order to ensure that workers save welding materials and reduce costs, the warehouse will require workers to return the remaining welding materials of the day to the warehouse for storage. However, due to the lack of supervision during the construction process, the warehouse cannot guarantee that all workers will return the remaining materials, and new welding materials will still be distributed the next day. Summary of the invention

[0004] In view of this, the present invention provides a welding wire warehouse personnel behavior management system to solve the above problems.

[0005] In order to solve the above technical problems, the present invention provides a welding wire warehouse personnel behavior management system, comprising:

[0006] A first identification terminal, a second identification terminal, and a third identification terminal that are connected to each other in communication; the first identification terminal is set at the entrance of the welding wire warehouse, the third identification terminal is set at the exit of the welding wire warehouse, and the second identification terminal is set at the material collection point; any identification terminal is equipped with an image acquisition device and a task recognition strategy for collecting and recording the behavior of personnel;

[0007] After the identification terminal completes the collection of personnel behavior, it calibrates the current behavior and the collection time, uploads the behavior timestamp and interacts with other terminal data, builds the personnel behavior timeline, and uploads the personnel behavior timeline to the management terminal for personnel management.

[0008] As an optional method, the task identification strategy is used to perform face recognition and behavior recognition on personnel after they complete identity tag recognition; face recognition is used to perform face verification and face registration on personnel using the current identification terminal, and behavior recognition is used to perform association verification on the task selected by the current personnel and the welding wire library platform.

[0009] As an optional approach, task identification strategies include:

[0010] After any person starts the identification terminal with the identity tag, the image acquisition device collects the image frame of the current area; if the face positioning frame cannot be used to confirm the face information in the image frame, the identification terminal parameters are initialized and then asked whether to exit;

[0011] If face information is detected in the image frame, face recognition is performed, and a face matching the current identity tag is searched in the face database. If the match fails, the user is asked whether to exit; and the recognition record is added to the behavior recognition log;

If the match is successful, the recognition record is added to the face recognition log, the behavior selection interface pops up, and the recognition record is added to the behavior recognition log.

[0013] As an optional method, face recognition is performed using the following method:

[0014] When face information is detected in the image frame, the face template matching the current identity tag in the face database is called, the texture features of the current face information and the face template are calculated, the similarity information is obtained, and the face comparison is performed based on the ratio of the similarity information to the preset information; wherein,

[0015] When performing face recognition, read the default face recognition times and recognize the current face information; if the comparison is successful, add the recognition record to the face recognition log, pop up the behavior selection interface, and add the recognition record to the behavior recognition log; if the comparison fails, increase the recognition times once and continue the recognition, perform illumination compensation, texture compensation and geometry compensation on the current face information and continue the recognition; if it still fails, ask whether to exit; and add the recognition record to the behavior recognition log.

[0016] As an optional method, after successful face recognition, the authority of the current identity tag is determined and the corresponding behavior selection interface pops up; when the behavior selection interface pops up, the current identification terminal establishes a communication connection with the corresponding welding wire library platform; wherein, the welding wire library platform is used to form a loading platform for storing welding wire reels and / or welding wires, and the welding wire library platform is equipped with a pressure-sensitive device for recording the pressure of the current platform; behavior recognition is used to associate and verify whether the behavior selection result is consistent with the pressure change of the welding wire library platform.

[0018] As an optional method, when the first recognition terminal successfully recognizes the face, it records the current time and continues to confirm the signal of the second recognition terminal and the third recognition terminal within a preset time; if within the preset time:

[0019] Upon receiving the recognition success information from the second recognition terminal, the device connects to the welding wire library platform, monitors the pressure feedback information from the welding wire library platform, and waits for the recognition feedback from the third recognition terminal;

[0020] If the recognition success information from the second recognition terminal is not received, the recognition success information from the third recognition terminal is waited for, and the face recognition record is recorded and uploaded to the management terminal.

[0021] As an optional method, the personnel behavior timeline includes personnel, timestamps, behavior records, and identification records. Constructing the personnel behavior timeline includes:

[0022] When the identity tag matches the face verification, the first identification terminal records the current person, the identification terminal verified by the current person, and the timestamp corresponding to the verification time;

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0032] See also Figure 1 The present embodiment provides a welding wire warehouse personnel behavior management system, including: a first identification terminal, a second identification terminal, and a third identification terminal that are connected to each other for communication; the first identification terminal is arranged at the entrance of the welding wire warehouse, the third identification terminal is arranged at the exit of the welding wire warehouse, and the second identification terminal is arranged at the material collection place; any identification terminal is configured with an image acquisition device and a task recognition strategy for collecting and recording personnel behavior; after the identification terminal completes the collection of personnel behavior, it calibrates the current behavior and the collection time, uploads the behavior timestamp and interacts with other terminal data, constructs a personnel behavior timeline, and uploads the personnel behavior timeline to the management terminal for personnel management.

[0033] In this embodiment, the identification terminal is any identification device with radio frequency identification function and equipped with a central processing unit. After being activated and started by the radio frequency identification function, it cooperates with the image acquisition device to identify the task information of the personnel. As an optional method, the task identification strategy is used to perform face recognition and behavior recognition on the personnel after the personnel completes the identity tag recognition; face recognition is used to perform face verification and face registration on the personnel using the current identification terminal, and behavior recognition is used to associate the task selected by the current personnel with the welding wire library platform. Please refer to Figure 1The second identification terminal is provided with at least one, which can be configured according to the density of the welding wire storage area.

[0034] Specifically, see Figure 2 ,Task identification strategies include:

[0035] After any person starts the identification terminal with the identity tag, the image acquisition device collects the image frame of the current area; if the face positioning frame cannot be used to confirm the face information in the image frame, the identification terminal parameters are initialized and then asked whether to exit;

[0036] If face information is detected in the image frame, face recognition is performed, and a face matching the current identity tag is searched in the face database. If the match fails, the user is asked whether to exit; and the recognition record is added to the behavior recognition log;

[0037] If face information is detected in the image frame, face recognition is performed and the face matching the current identity tag is searched in the face database. If the match is successful, the recognition record is added to the face recognition log, the behavior selection interface pops up, and the recognition record is added to the behavior recognition log.

[0038] In this way, when the administrator or operator uses an identity tag such as a work badge or NFC card to activate the identification terminal, the system of this embodiment will determine and track the purpose of their entry into the warehouse. And through face recognition, it is guaranteed to match the identity tag to avoid mistaking or wrongly taking materials and causing confusion in storage records. In addition, considering that operators in the welding wire storage environment may have facial contamination due to outdoor, dusty, high temperature and other reasons, which may affect facial recognition, as an optional method, please refer to Figure 3 , this embodiment adopts the AAM model to recognize faces, which includes:

[0039] When face information is detected in the image frame, the face template matching the current identity tag in the face database is called, the texture features of the current face information and the face template are calculated, the similarity information is obtained, and the face comparison is performed based on the ratio of the similarity information to the preset information; when performing face recognition, the default face recognition times are read and the current face information is recognized; if the comparison is successful, the recognition record is added to the face recognition log, the behavior selection interface pops up, and the recognition record is added to the behavior recognition log; if the comparison fails, the recognition times are increased once to continue the recognition, and the current face information is compensated for illumination, texture and geometry, and then the recognition is continued. If it still fails, it is asked whether to exit; and the recognition record is added to the behavior recognition log. This can minimize the error verification of personnel entering the warehouse.

[0040] In some optional scenarios, the welding wire reels and / or welding wires are stored on shelves or loading platforms, and significant weight changes will occur when they are stored and retrieved. Therefore, the behavior selection interface can optionally include picking and storing materials. When the current behavior is selected as picking, the identification terminal verifies whether the pressure on the welding wire storage platform is reduced within a preset time; when the current behavior is selected as storing materials, the identification terminal verifies whether the pressure on the welding wire storage platform is increased within a preset time; if it meets the preset association, the recognition record is added to the behavior recognition log.

[0041] Therefore, after the face recognition is successful, the authority of the current identity tag is determined and the corresponding behavior selection interface pops up; when the behavior selection interface pops up, the current identification terminal establishes a communication connection with the corresponding welding wire warehouse platform; wherein, the welding wire warehouse platform is used to form a loading platform for storing welding wire reels and / or welding wires, and the welding wire warehouse platform is equipped with a pressure-sensitive device for recording the pressure of the current platform; behavior recognition is used to associate and verify whether the behavior selection result is consistent with the pressure change of the welding wire warehouse platform. It can ensure that the operator's behavior can be recorded and verified. Optionally, the image acquisition device can also be set to shoot at the shelf or the welding wire warehouse platform, so that the operator's task data can be recorded at the identification terminal, and his behavior can be traced through the image. It is also possible to adjust the angle of the image acquisition device on all identification device ends, and re-collect the operator's hand area, and further avoid the situation of wrong receipt, wrong delivery, and false receipt and misuse through the changes in the materials held by the operator.

[0042] In addition, personnel can be further controlled. When the first recognition terminal successfully recognizes a face, it records the current time and continuously sends signals to the second and third recognition terminals at a preset time. If the second recognition terminal receives successful recognition information within the preset time, it connects to the welding wire library platform, monitors the pressure feedback information of the welding wire library platform, and waits for the recognition feedback of the third recognition terminal. If the second recognition terminal does not receive successful recognition information, it waits for the third recognition terminal to receive successful recognition information, records the face recognition record, and uploads it to the management terminal. Avoid confusion or omissions in personnel records.

[0043] In order to better manage personnel and warehouse materials, this embodiment does not limit the form of the management terminal, which can be any software and / or hardware that can communicate with the identification device. The management terminal stores the personnel behavior timeline, personnel behavior information, personnel movement information and multiple image frames; the image frames include face information, material change information of the welding wire library platform and personnel handheld image information. This makes it convenient to manage the flow and material changes in the warehouse.

[0044] Optionally, the personnel behavior timeline includes personnel, timestamps, behavior records and identification records. Constructing the personnel behavior timeline includes: when the identity tag matches the face verification, the first identification terminal records the current person, the identification terminal verified by the current person, and the timestamp corresponding to the verification time; the second identification terminal reads the identification timestamp of the third identification terminal, reads the behavior identification information of the second identification terminal, reads the pressure information of the welding wire library platform, constructs the personnel behavior timeline, and records the personnel behavior information. The behavior information also includes movement information, and the movement information includes the positioning information of the first identification terminal, the positioning information of the third identification terminal, and the second identification terminal positioning information corresponding to the identification information of any second identification terminal distributed along the timeline. Through the information of time and place, the movement trajectory of each person entering the warehouse can be drawn, which can further realize the material and personnel management of the welding wire library and improve the efficiency of warehouse use and management.

[0045] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention, and the protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
