Description

Technical Field

[0001] This invention belongs to the field of attendance system technology, specifically relating to an attendance and record generation system and method based on vehicle gate opening event data. Background Technology

[0002] Attendance management is a fundamental management system for enterprises, serving as a crucial tool to ensure employees are present and working within designated areas within specified times. A standardized and reasonable attendance system effectively guarantees work efficiency and productivity, and attendance data is also the basis for many companies to pay employee salaries. With the increasing prevalence of vehicle travel, the security management of parking lots and vehicle access control in large office buildings has become increasingly important. However, traditional attendance and record generation methods, such as manual sign-in and card swiping, suffer from problems such as high workload, susceptibility to tampering, and susceptibility to errors. Furthermore, existing license plate recognition systems are typically used for parking space management in underground garages and cannot be integrated with company attendance systems.

[0003] To address the shortcomings of existing technologies, people have conducted long-term explorations and proposed various solutions. For example, Chinese patent literature discloses a license plate recognition attendance management system and method [201811223637.1]. ​​Its WCCS network server is connected to a WCCS network client. The WCCS network client is connected to the license plate recognition module, LED display module, vehicle group module, group permission module, and parking space management module, respectively. The license plate recognition camera is connected to the WCCS network server through the license plate recognition module and the SDK external port in sequence. The vehicle group module, group permission module, and parking space management module are all connected to the WCCS network server. The WCCS network server is connected to the WCCS network client through a query module.

[0004] The above solution has solved the problem of combining license plate recognition with attendance tracking to some extent, but it still has many shortcomings, such as the inability to guarantee the effectiveness of parking lot and vehicle entry and exit security management. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a reasonably designed attendance and record generation system based on vehicle gate opening event data that combines license plate recognition and attendance tracking.

[0006] Another objective of this invention is to address the aforementioned problems by providing an attendance and record generation method based on vehicle gate opening event data to ensure the security of vehicle entry and exit management.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an attendance and record generation system based on vehicle gate opening event data, comprising a vehicle gate mechanism, a parking space monitoring mechanism, and a monitoring platform connecting the vehicle gate mechanism and the parking space monitoring mechanism to an attendance system. The attendance system is connected to a cloud platform and a mobile terminal. The interconnection between the vehicle gate mechanism and the attendance system enables contactless attendance upon vehicle entry, and the monitoring platform monitors for any attendance anomalies, ensuring the accuracy of license plate recognition and attendance recording.

[0008] In the aforementioned attendance and record generation system based on vehicle gate opening event data, the vehicle gate mechanism includes an entrance gate and an exit gate. Each entrance and exit gate is equipped with a detection component and a touch display module. The detection component is connected to the internal mechanism of the entrance and exit gates via a main control module. The detection component includes a camera and an infrared sensor, and pressure sensors are installed on the ground around the entrance and exit gates. The parking space monitoring mechanism includes a pressure plate laid on the parking space floor. A pressure sensor is installed between the pressure plate and the ground, and an infrared sensor is mounted on the upper part of the pressure plate. Indicator lights are also installed on the pressure plate. The vehicle gate mechanism monitors vehicles at the garage entrance and exit, working in conjunction with the parking space monitoring mechanism to achieve effective vehicle parking planning.

[0009] In the aforementioned attendance and record generation system based on vehicle gate opening event data, the attendance system is based on a B / S architecture and includes a connected client and a web server. The web server is connected to the database and the time clock. The attendance system includes an employee module, an enterprise module, and a management module. The employee module includes user information, daily attendance, leave attendance, business trip attendance, overtime attendance, and permission queries. The enterprise module includes employee management, financial management, administrative management, and department manager functions. The management module includes user login, permission management, attendance query, attendance approval, and visitor management. The attendance system meets the enterprise management needs, managing employees and visitors separately.

[0010] A method for attendance and record generation based on vehicle gate opening event data includes the following steps:

[0011] S1: When a vehicle enters the parking space, the vehicle gate mechanism identifies the vehicle;

[0012] S2: The vehicle barrier mechanism determines whether a vehicle is an internal employee vehicle or an external visitor vehicle, and the monitoring platform controls whether the vehicle barrier mechanism allows passage.

[0013] S3: Transmit the collected vehicle data and employee or visitor identity information to the attendance system for management of employees and visitors respectively;

[0014] S4: The attendance system generates employee attendance records or visitor profiles and uploads them to the cloud platform.

[0015] S5: When a vehicle leaves the warehouse, the vehicle gate mechanism verifies the vehicle and performs a second attendance check for employees or verifies the visitor's file. Employees and visitors are identified and managed separately, and independent files are established to ensure the accuracy of attendance management.

[0016] In the above-mentioned attendance and record generation method based on vehicle gate opening event data, step S2 includes the following steps:

[0017] S21: Collect license plate images, compare the license plate information with the database to determine whether it is an internal vehicle. If it is an internal vehicle, proceed to step S12; otherwise, determine it as an external visitor.

[0018] S22: The vehicle barrier mechanism collects the passenger's facial image, compares the facial information with the database to determine whether there is an internal employee. If it is an internal employee, proceed to step S12; otherwise, it is determined to be an external visitor.

[0019] S23: The vehicle gate mechanism releases the vehicle. When the vehicle passes through, the pressure of the front and rear wheels and the ground are collected, and the vehicle weight is obtained.

[0020] In the above-mentioned attendance and record generation method based on vehicle gate opening event data, step S2 includes the following steps:

[0021] S24: After a vehicle is parked in a parking space, the parking space monitoring agency checks the vehicle's weight. If the weight exceeds the deviation range, a warning signal is sent to the monitoring platform.

[0022] S25: The parking space monitoring mechanism detects changes in vehicle weight, compares the vehicle weight variable with a preset range, determines the number of passengers, and if there is a discrepancy with the vehicle gate mechanism, sends an alarm signal to the monitoring platform.

[0023] In the above-mentioned attendance and record generation method based on vehicle gate opening event data, step S3 includes the following steps:

[0024] S31: Transmit the vehicle entry time, employee name, employee ID, visitor name, and visitor facial image to the attendance system;

[0025] S32: Determine whether the employee is late based on the vehicle entry time. If the employee is late, determine whether they have requested leave. If they have requested leave, proceed to step S33; otherwise, mark them as late.

[0026] S33: Set thresholds for the number of times a vehicle enters and exits and the parking time. If the thresholds are exceeded, the system will switch to regular attendance.

[0027] S34: Employees submit objection requests via mobile devices. The attendance system sends the objection requests to the management department. If the objection is approved, the attendance exception is cancelled.

[0028] S35: External visitors supplement their personal information through the vehicle gate mechanism and call the monitoring platform for permission to pass.

[0029] In the above-mentioned attendance and record generation method based on vehicle gate opening event data, the visitor profile in step S4 includes vehicle license plate, vehicle characteristics, visitor name, visitor facial image, reason for visit, and visit time.

[0030] In the above-mentioned attendance and record generation method based on vehicle gate opening event data, step S5 includes the following steps:

[0031] S51: Recognize the license plate image. If it is an external visitor vehicle, proceed to step S51.

[0032] S52: Visitors can view their personal profiles via the touch display module and choose to save or delete them;

[0033] S53: The vehicle barrier mechanism verifies the weight of the entire vehicle and sends the inspection information to the monitoring platform;

[0034] S53: The monitoring platform controls the vehicle gate mechanism to automatically release vehicles or conduct manual inspections.

[0035] In the above-mentioned attendance and record generation method based on vehicle gate opening event data, step S5 includes the following steps:

[0036] S54: Recognize the license plate image; if it is an internal employee vehicle, proceed to step S55.

[0037] S55: Collect passenger facial images, compare and determine whether they are internal employees, and if they are internal employees, clock in and out.

[0038] S56: The vehicle gate mechanism verifies the weight of the vehicle and allows it to pass. If the weight is within the preset range, the attendance is recorded normally; otherwise, an abnormality report is sent to the monitoring platform.

[0039] Compared with existing technologies, the advantages of this invention are as follows: the vehicle barrier mechanism and the parking space monitoring mechanism respectively verify the vehicle and the onboard personnel, thereby realizing the combination of parking space management and attendance check-in; the attendance system manages internal employees and external visitors independently, maintaining the security of personnel flow control; and gravity sensing is used for vehicles and onboard personnel to improve the accuracy of enterprise access control and ensure the accuracy of attendance record generation.

[0041] Figure 2 This is a schematic diagram of the attendance system of the present invention;

[0042] Figure 3 This is a schematic diagram of the method principle of the present invention;

[0043] Figure 4 This is a schematic diagram illustrating the identification of employees and visitors according to the present invention;

[0044] In the diagram, the components are: vehicle barrier mechanism 1, entrance barrier 11, exit barrier 12, detection component 13, touch display module 14, main control module 15, mechanism 16, parking space monitoring mechanism 2, pressure plate 21, indicator light 22, monitoring platform 3, attendance system 4, client 41, web server 42, database 43, time clock 44, cloud platform 5, and mobile terminal 6. Detailed Implementation

[0045] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0046] like Figure 1-2 As shown, an attendance and record generation system based on vehicle gate opening event data is typically used for parking space management in corporate garages. Specifically, it includes a vehicle gate mechanism 1 installed at the garage entrance / exit to control vehicle entry and exit. The vehicle gate mechanism 1 is equipped with a parking space monitoring mechanism 2, which corresponds to each parking space to monitor the parking status. Unlike conventional gate systems, the vehicle gate mechanism 1 and parking space monitoring mechanism 2 in this application are connected to an attendance system 4 via a monitoring platform 3. When a vehicle enters or exits, contactless attendance is automatically completed for employees. The attendance system 4 is connected to a cloud platform 5 and a mobile terminal 6. Employee attendance records are uploaded to the cloud platform 5 for backup, and managers or employees can view the attendance records via a built-in app on a mobile terminal 6 such as a smartphone / tablet.

[0047] Specifically, the vehicle barrier mechanism 1 typically uses a lifting lever to control the opening and closing of the vehicle passage, including an entrance barrier 11 and an exit barrier 12 to control the entry and exit of vehicles. The entrance barrier 11 and exit barrier 12 are each equipped with a detection component 13 and a touch display module 14. The detection component 13 collects vehicle information, and the touch display module 14 provides information prompts to visitors, guiding them to verify their identity. The detection component 13 is connected to the internal mechanism 16 of the entrance barrier 11 and exit barrier 12 via a main control module 15, and the mechanism 16 drives the barrier to swing the barrier lever.

[0048] The detection component 13 includes a camera and an infrared sensor. The camera primarily captures license plate and passenger facial images, and uses a feature extraction mechanism to collect vehicle color, size, and other features to ensure system recognition accuracy. The infrared sensor detects whether a vehicle is passing and determines the overall vehicle length based on its speed. Pressure sensors are installed on the ground at the entrance gate 11 and exit gate 12 to measure the pressure between the front and rear wheels of the vehicle and the ground. The parking space monitoring mechanism 2 includes a pressure plate 21 laid on the parking space floor to distribute the pressure of the vehicle. A pressure sensor is installed between the pressure plate 21 and the ground to sense the weight of the vehicle when stationary. An infrared sensor is installed on the upper end of the pressure plate 21, and an indicator light 22 is installed on the pressure plate 21. The infrared sensor detects whether the vehicle is accurately positioned, and the indicator light 22 guides the vehicle, directing internal employees and external visitors to different areas, thereby achieving traffic management.

[0049] In detail, the attendance system 4 is based on a B / S architecture and includes a connected client 41 and a web server 42. The web server 42 is connected to a database 43 and a time clock 44. It can also be described as having a user interface layer, a logic layer, and a data layer. System interaction is achieved through a web browser on the client 41. The client 41 sends requests to the web server 42, which performs logical processing and exchanges data with the database 43. Nginx and Node are also deployed on the client 41 and web server 42 to reduce transmission load and meet the large number of data requests from the client 41.

[0050] The attendance system 4 includes an employee module, an enterprise module, and a management module, managing the employee level and the administrative level independently. The employee module includes user information, daily attendance, leave attendance, business trip attendance, overtime attendance, and permission queries. Ordinary employees can select the appropriate attendance mode through client 41 and raise objections to abnormal attendance. The enterprise module includes employee management, financial management, administrative management, and department manager functions to meet ERP management needs. The management module includes user login, permission management, attendance query, attendance approval, and visitor management. Administrators can use the management module to perform operations such as account modification, attendance management, and visitor registration.

[0051] like Figure 3 As shown, an attendance and record generation method based on vehicle gate opening event data automatically generates corresponding attendance records when vehicles enter or leave the warehouse, and adopts different processing procedures for employees and visitors. The specific steps include the following:

[0052] S1: When a vehicle enters the parking space, the camera on the vehicle barrier mechanism 1 recognizes the vehicle's license plate and external outline, and after analog-to-digital conversion, compares and judges it with the database.

[0053] S2: The vehicle barrier mechanism 1 determines whether the vehicle is an internal employee vehicle or an external visitor vehicle. The monitoring platform 3 controls whether the vehicle barrier mechanism 1 allows passage. The touch display module 14 guides the vehicle to park in the designated parking space and is verified by the parking space monitoring mechanism 2.

[0054] S3: Transmit the collected vehicle data and employee or visitor identity information to the attendance system 4 for the management of employees and visitors respectively;

[0055] S4: The attendance system 4 generates employee attendance records or visitor files, and uploads them to the cloud platform 5 for backup. The attendance records and files can be checked using a mobile terminal 6.

[0056] S5: When a vehicle leaves the warehouse, the vehicle gate mechanism 1 verifies the vehicle, performs a second attendance check for employees, or verifies the visitor's file to ensure data security.

[0057] like Figure 4 As shown, step S2 includes the following steps:

[0058] S21: Collect license plate image, compare the license plate information with database 43 to determine whether it is an internal vehicle. If it is an internal vehicle, proceed to step S12; otherwise, determine it as an external visitor and allow it to pass directly after identity verification.

[0059] S22: The vehicle gate mechanism 1 collects the passenger's facial image and compares the facial information with the database 43 to determine whether there is an internal employee. In addition to using a camera for facial verification, fingerprint and other contact verification mechanisms can be added to the vehicle gate mechanism 1. If the passenger is an internal employee, proceed to step S12 to check the vehicle itself; otherwise, determine that the passenger is an external visitor and allow passage.

[0060] S23: The vehicle barrier mechanism 1 opens to allow vehicles to pass through. When a vehicle passes through, the pressure sensors collect the pressure of the front and rear wheels of the vehicle on the ground and obtain the vehicle's total weight. The pressure is then checked against the pressure measured by the subsequent parking space monitoring mechanism 2. The vehicle's center of gravity is determined based on the overall vehicle length and the front and rear wheel bearing ratio.

[0061] Furthermore, step S2 includes the following steps:

[0062] S24: After the vehicle is parked in the parking space, the parking space monitoring agency 2 checks the vehicle's weight. If the weight exceeds the deviation range, a warning signal is sent to the monitoring platform 3.

[0063] S25: The parking space monitoring mechanism 2 detects changes in vehicle weight, compares the vehicle weight variable with a preset range, and determines the number of passengers. If there is a discrepancy with the vehicle gate mechanism 1, an alarm signal is sent to the monitoring platform 3. In this step, the pressure sensors measure the pressure on the bearing plates 21 that are in contact with the front and rear wheels, and determine the vehicle's center of gravity position based on the overall vehicle length. By comparing the center of gravity position with that measured by the vehicle gate mechanism 1, it is determined whether the passengers have disembarked. The system is then verified against the passenger data collected by the vehicle gate mechanism 1 to track employees or visitors one by one.

[0064] In addition, step S3 includes the following steps:

[0065] S31: Transmit the vehicle entry time, employee name, employee ID, visitor name, and visitor facial image to the attendance system 4 for summarization and storage, and generate corresponding reports;

[0066] S32: Determine whether the employee is late based on the vehicle entry time. If the employee is late, determine whether they have requested leave. If they have requested leave, proceed to step S33; otherwise, mark them as late.

[0067] S33: Set thresholds for the number of times a vehicle enters and exits and the parking time. If the threshold is exceeded, the system will switch to regular attendance. Setting thresholds can eliminate attendance abnormalities caused by temporary entry and exit.

[0068] S34: Employees submit objection requests via mobile terminal 6, and attendance system 4 sends the objection requests to the management department. If the objection is approved, the attendance exception is cancelled.

[0069] S35: External visitors supplement their contact information and other personal data through the vehicle gate mechanism 1, and call the monitoring platform 3 to allow them to pass through by manual verification.

[0070] Meanwhile, in step S4, the visitor file includes vehicle license plate, vehicle characteristics, visitor name, visitor facial image, reason for visit, and visit time. The manager retrieves the visitor file through the attendance system 4 and edits and corrects it through the client 41. The visitor file is pre-stored in the database 43, and the vehicle barrier mechanism 1 directly allows the visitor to pass after comparing the visitor with the pre-stored file.

[0071] As can be seen, step S5 includes the following steps:

[0072] S51: Recognize the license plate image. If it is an external visitor vehicle, proceed to step S51.

[0073] S52: Visitors can check their personal profiles via the touch display module 14 and choose to save or delete them, thereby distinguishing between temporary visitors and non-temporary visitors;

[0074] S53: The vehicle barrier mechanism 1 verifies the weight of the vehicle and sends the inspection information to the monitoring platform 3, classifying the vehicle type into the customer file;

[0075] S53: The monitoring platform 3 controls the vehicle gate mechanism 1 to automatically release or conduct manual inspections, further improving the security of enterprise personnel management.

[0076] Clearly, step S5 includes the following steps:

[0077] S54: Recognize the license plate image; if it is an internal employee vehicle, proceed to step S55.

[0078] S55: Collect passenger facial images, compare and determine whether they are internal employees, and if they are internal employees, clock in and out.

[0079] S56: The vehicle gate mechanism 1 verifies the weight of the vehicle and allows it to pass. If the weight is within the preset range, the attendance is recorded normally; otherwise, an abnormal report is sent to the monitoring platform 3.

[0080] In summary, the principle of this embodiment is as follows: the vehicle gate mechanism 1 and the parking space monitoring mechanism 2 cooperate to check vehicles entering and exiting, distinguishing between internal employees and external visitors. When internal employees' vehicles enter or exit the parking space, the vehicle gate mechanism 1 verifies their identity and uploads it to the attendance system 4 for automatic attendance check-in. For external visitors, an independent customer file is established for classified management.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.

[0082] Although this document frequently uses terms such as vehicle barrier mechanism 1, entrance barrier 11, exit barrier 12, detection component 13, touch display module 14, main control module 15, mechanism 16, parking space monitoring mechanism 2, pressure plate 21, indicator light 22, monitoring platform 3, attendance system 4, client 41, web server 42, database 43, time clock 44, cloud platform 5, and mobile terminal 6, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
