Description

Technical Field

[0001] This disclosure relates to the field of attendance tracking technology, and more particularly to a method and apparatus for attendance tracking in a coal preparation plant. Background Technology

[0002] Currently, the coal preparation plant uses a traditional handwritten sign-in method when entering the work area, similar to sign-in for daily meetings. The sign-in information includes name, job title, and arrival time. This traditional method requires pre-prepared sign-in sheets, a secretary reminding staff to sign in, and dedicated personnel to track, remind, and pass on the sheets. It is also prone to errors and inaccuracies, sometimes requiring re-signing, and discrepancies between the sign-in time and the actual arrival time. This traditional sign-in method is costly to manage, inefficient, and lacks standardized record-keeping. Summary of the Invention

[0011] If the similarity of all the images to be matched is less than the preset threshold, a matching failure message is generated and sent to the system administrator.

[0012] Optionally, the step of obtaining the target position corresponding to the target permission based on the current duty roster specifically includes:

[0013] If there is only one target permission for the target identity, and the target permission is the permission of the person in charge of the target position, then the current person is determined to be the person in charge of the target position.

[0014] If there is only one target permission for the target identity, and the target permission is the permission of the substitute for the target position, then the target position is determined based on the attendance of the person in charge of the target position.

[0015] Optionally, the step of determining the target position based on the attendance of the person in charge of the target position specifically includes:

[0016] In response to the fact that the person in charge of the target position has arrived at their post, the current person is identified as the assistant for the target position;

[0017] In response to the absence of the person in charge of the target position, the current person is determined to be the temporary person in charge of the target position.

[0018] Optionally, the step of obtaining the target position corresponding to the target permission based on the current duty roster further includes:

[0019] If there are more than one target permission for the target identity, the position corresponding to the target identity in the current duty roster is determined as the target position.

[0020] Optionally, the method further includes:

[0021] In response to the fact that the target permission is the permission of a substitute for the target position, and the person in charge of the target position has arrived at the post, the current person is determined to be the assistant of the target position;

[0022] In response to the fact that the target permission is the permission of a substitute for the target position, and the person in charge of the target position is not present, the current person is determined to be the temporary person in charge of the target position.

[0023] Optionally, the method further includes:

[0024] According to a second aspect of the present disclosure, a check-in device for a coal preparation plant is provided, comprising:

[0025] The identity recognition module is used to respond to the check-in operation by capturing the facial image of the current person and recording the arrival time, and then matching the facial image to determine the target identity of the current person.

[0026] The job confirmation module is used to determine the target's permissions based on the target's identity and to obtain the target job corresponding to the target's permissions based on the current duty roster.

[0027] The table generation module is used to generate a response sign-in table based on the target identity, target position, and arrival time.

[0028] According to a third aspect of the present disclosure, an electronic device is provided, comprising:

[0029] processor;

[0034] The technical solutions provided by the embodiments of this disclosure have at least the following beneficial effects:

[0035] With this check-in method, staff can basically pass through without stopping when entering the designated area, and the facial recognition system completes the collection of facial information, identification of personnel, and recording of arrival time.

[0036] After facial recognition system identifies an individual, it transmits the information to the attendance system, which then matches the individual with their assigned position, ultimately generating a complete summary table of individual identity information, position, and arrival time. This replaces the traditional method of handwritten attendance sheets and improves upon the original process of identifying staff through system login, resulting in faster, more accurate, and more complete attendance records, and better suited to various complex situations.

[0037] This disclosure identifies the target's identity by extracting facial images from the current person's image, and obtains the target's permissions and position corresponding to the target identity, making the check-in response faster and more accurate.

[0046] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0047] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0048] It should be noted that the user information involved in this disclosure (including but not limited to user device information, user personal information, etc.) is all information authorized by the user or fully authorized by all parties.

[0049] Currently, domestic coal preparation plants use two methods for staff to sign in when entering the work area: one is the traditional handwritten signature, similar to signing in for daily meetings, which includes the name, job title, and arrival time; the other is to sign in by logging into the sign-in system using a specific job code or identity code and password.

[0050] Traditional handwritten signatures require advance preparation of sign-in sheets, and secretaries need to remind staff to sign in. The sign-in process requires a dedicated person to track, remind, and pass on the sign-in sheets. In the process, it is easy for the sheets to be filled out incorrectly or even incorrectly, which may result in the sign-in sheets needing to be rewritten. The sign-in time may also be inconsistent with the actual arrival time. This traditional sign-in method has high management costs, low efficiency, and poor record-keeping.

[0051] To address the shortcomings of handwritten attendance records, some organizations have experimented with using specific job codes or identity codes and passwords to log in to the attendance system. However, this method relies on logging into the system to complete the attendance check-in. While it shows that a specific employee is present at their post, only one employee can be displayed for the same post at a time. This cannot fully meet the needs of multiple employees on duty simultaneously during actual responses / exercises. The attendance check-in time is based on the login time and lags behind the actual time of entering the premises and beginning to assume responsibilities.

[0052] Figure 1 This is a flowchart illustrating a check-in method in a coal preparation plant according to an exemplary embodiment. Figure 1 As shown, the method includes:

[0053] Step 101: In response to the check-in operation, take an image of the current person, obtain the face region in the image through a neural network to generate a face image, match the face image to determine the target identity of the current person, and record the arrival time of the image being taken.

[0054] In this embodiment, the facial recognition technology that has been developed and matured is used to input the facial information of authorized personnel within the company into the facial recognition system, and a facial collection and recognition system is set up at the entrance of the command center or similar response location.

[0055] The system is relatively mature and consistent with the power plant area management system. First, facial information is collected from authorized personnel. Facial recognition systems are set up at the entrances of corresponding locations. When staff enter the location, the system collects the image of the current person, identifies the facial region containing the face in the image through a neural network, extracts the image of the region to generate a facial image, and compares the facial image with a facial database to identify the identity of the person entering and records the entry time. This generates a summary table of personnel identity and entry time (name, arrival time), realizing automatic recording of personnel identity recognition and arrival time.

[0056] Step 102: Determine the target authority based on the target identity, and obtain the target position corresponding to the target authority based on the current duty roster;

[0057] In this embodiment, the facial recognition system uploads the recognition results and time information of the personnel entering the room to the check-in system. The check-in system compares the personnel's identity with the authorization information they have obtained, and matches the position of the personnel entering the room with the authorization information and the current duty roster.

[0058] Step 103: Generate a response sign-in sheet based on the target identity, target position, and arrival time.

[0059] In this embodiment, the check-in system generates a check-in report in the form of a report, which includes the personnel's identity, job position, and arrival time (the time of first entry into the corresponding place and the time of taking up a certain job position).

[0060] Figure 2 This is a flowchart illustrating a check-in method in a coal preparation plant according to an exemplary embodiment. Figure 2 As shown, Figure 1 Step 101 specifically includes:

[0061] Step 201: Extract the facial features of the face image and calculate the similarity with the facial features of the undetermined image in the authorized face information database;

[0062] In this embodiment, facial recognition systems are installed at various locations to establish a facial information database for authorized personnel or those who may assume response responsibilities in special circumstances. Specifically, the facial images of authorized personnel are stored as pending images in the authorized facial information database, along with the corresponding identity information. After acquiring a facial image, it is compared with the pending images in the authorized facial information database to determine whether the current person is authorized. This embodiment uses a pre-trained facial matching neural network to extract high-dimensional features from the facial image, generating a first feature vector, which is then compared with a second feature vector corresponding to the pending image. In actual execution, the facial image and the pending image are input together into the facial matching neural network. The encoder in the facial matching neural network extracts features to generate a first feature vector and a second feature vector. Then, the first and second feature vectors are multiplied to generate a third feature vector. Finally, the third feature vector is input into the decoder in the facial matching neural network to generate a similarity score. Similarity represents the degree of matching between a face image and a target image. The value of similarity ranges from [0, 1]. The higher the similarity value, the higher the degree of matching between the face image and the target image.

[0063] Step 202a: If there is a candidate image with a similarity higher than a preset threshold, the candidate image that matches the face image is determined as the target image, and the target identity of the current person is determined based on the target image;

[0064] This embodiment determines whether a match is achieved by setting a threshold. In one possible embodiment, the preset threshold is 0.95.

[0065] Step 202b: If the similarity of all the images to be determined is less than the preset threshold, a matching failure message is generated and sent to the system administrator.

[0066] For individuals whose facial information is not registered in the facial information database, the system will collect and record their facial information when they enter the corresponding venue, and display a message on the screen saying "You are not authorized and cannot enter. If you need to enter, please contact the administrator." Once the administrator confirms that the person needs to enter the venue, they can open the entry channel with the administrator's identity. The system will record the facial image and entry time when the person enters.

[0067] Optionally, step 102, which involves obtaining the target position corresponding to the target authority based on the current duty roster, specifically includes:

[0068] Step 301a: In response to the fact that there is only one target permission for the target identity, and the target permission is the permission of the person in charge of the target position, then the current person is determined to be the person in charge of the target position.

[0069] In this embodiment, for personnel who have only been authorized by one person in charge of a position, facial recognition will automatically assume that the personnel has taken on the position. For example, if employee A is only authorized by the person in charge of the command center, the system will automatically record employee A as the person in charge of the command center after recognizing that employee A has arrived at the post.

[0070] Step 301b: In response to the fact that there is only one target permission for the target identity, and the target permission is the permission of the substitute for the target position, the target position is determined according to the on-duty status of the person in charge of the target position.

[0071] In this embodiment, for each target position, there are designated personnel and substitutes to prevent work stoppages caused by staff inability to perform their duties. For personnel authorized to substitute for only one position, the system will determine their eligibility through facial recognition. If the designated personnel for the same position are not present, the substitute will serve as a temporary designated personnel. Once the designated personnel arrive, the temporary designated personnel will become the designated personnel's assistant. If the designated personnel for the same position are present, the substitute will serve as the designated personnel's assistant.

[0072] Optionally, step 301b, which determines the target position based on the attendance of the person in charge of the target position, specifically includes:

[0073] Step 302a: In response to the fact that the person in charge of the target position has arrived at the post, determine that the current person is the assistant of the target position;

[0074] Step 302b: In response to the absence of the person in charge of the target position, determine the current person as the temporary person in charge of the target position.

[0075] Optionally, step 102, which involves obtaining the target position corresponding to the target authority based on the current duty roster, further includes:

[0076] If there are more than one target permission for the target identity, the position corresponding to the target identity in the current duty roster is determined as the target position.

[0077] Because the job divisions in coal plants are quite detailed, some personnel may be assigned different response tasks under different circumstances. These individuals will be authorized for more than one position. For those who have been authorized to take on or substitute for multiple positions, the sign-in system will prioritize matching them to the appropriate position based on the job assignments for the current shift (generally one week is a shift cycle). For example, if Zhang San is assigned to both the positions of secretary and office director, but is assigned to the secretary position this week, the system will automatically record him as the secretary after he arrives at his post, instead of the office director.

[0078] Optionally, the method further includes:

[0079] Step 303a: In response to the fact that the target permission is the permission of a substitute for the target position, and the person in charge of the target position has arrived at the post, determine that the current person is the assistant of the target position;

[0080] Step 303b: In response to the fact that the target permission is the substitute permission for the target position, and the person in charge of the target position is not present, determine that the current person is the temporary person in charge of the target position.

[0081] Figure 3 This is a schematic diagram illustrating the structure of a check-in system according to an exemplary embodiment. For example... Figure 3 As shown, this check-in system consists of two parts: a facial recognition system, which identifies personnel and records the time of arrival at a specific location; and a check-in system, which identifies and matches the identified personnel to their job positions, ultimately generating a table that associates information about personnel, job positions, and arrival times.
