Description

Technical Field

[0001] This utility model relates to the field of personnel management technology, and in particular to a ship repair and construction personnel statistics system based on contactless check-in. Background Technology

[0002] Shipbuilding companies often require long-term repair and construction operations on multiple vessels, involving a large and constantly changing workforce, resulting in overlapping work. Managers lack the technical means to monitor the number of personnel on each vessel in real time, and are also unable to obtain manpower and related statistics for vessels requiring urgent delivery.

[0003] Seamless attendance tracking is based on RFID technology, which places RFID tags in the clothing and hats worn by employees. It can automatically identify personnel from a distance through RFID radio frequency identification equipment. However, it does not have a specific solution for the problems of multiple work areas, high flexibility and high personnel mobility in shipbuilding and repair operations. Summary of the Invention

[0004] This disclosure provides a system for counting the number of employees in a vessel's work area based on contactless attendance technology. It combines RFID radio frequency identification devices to provide directions for personnel entering and exiting and reduce the data loss rate. Through the management platform, it can accurately grasp data such as the number of employees, employee information, entry and exit times, and work time of each vessel in the work area. This can not only improve the efficiency of employee access identification, but also be applied to some scenarios where faces are covered or fingerprint attendance is inconvenient.

[0005] The ship repair and construction personnel statistics system based on contactless attendance provided in this public disclosure includes:

[0006] RFID tags are worn by workers, and the data in the tags includes: employee ID information and the equipment's own serial number;

[0007] The identification equipment group includes at least two RFID radio frequency identification devices with network transmission capabilities. These devices are installed at the beginning and end of the boarding ladders of each working vessel or the passage ladders between vessels. When workers pass by, the RFID radio frequency identification devices in the identification equipment group read the RFID tags worn by the workers in the order of passing by, and transmit the data from the tags to the data acquisition and processing module through the network transmission function.

[0008] The data acquisition and processing module is used to collect and process the received data, determine the order in which operators trigger the identification devices in the same identification device group based on the data, determine whether they enter or leave a vessel, and update the number of operators on each vessel.

[0009] Furthermore, each worker wears an RFID tag consisting of a first RFID tag and a second RFID tag, which are symmetrically affixed to the inside of the worker's safety helmet.

[0010] Furthermore, each identification device group includes three RFID radio frequency identification devices with network transmission capabilities, which are evenly installed at the head, middle, and stern positions of the boarding ladder of each working vessel or the passage ladder between vessels.

[0011] Furthermore, all of the RFID radio frequency identification devices are equipped with 4G and / or 5G network transmission modules.

[0012] Furthermore, it also includes a display module, which dynamically displays the location of the operators and the specific number of personnel working on each vessel.

[0013] Furthermore, the display module includes a web-based display module and a mobile-based display module.

[0014] Compared with existing technologies, the beneficial effects of this disclosure are: ① It enables seamless attendance tracking for shipbuilding and repair workers by combining RFID tags and card readers, avoiding the dependence on worker initiative and management difficulties inherent in traditional card-swiping systems; ② By adding equipment groups on the boardwalks between inner and outer vessels, the system can track the specific number of workers on each vessel, achieving precise statistical granularity down to the vessel level; ③ Compared to traditional card-swiping systems, this disclosure can achieve second-level data update speeds, with personnel location update delays of less than 5 seconds; ④ Combined with the web and mobile interfaces provided by the software platform, it allows managers to monitor the real-time location dynamics of workers, while also providing a data foundation for managers to analyze the work status, work hours, and labor costs of shipbuilding and repair workers.

[0018] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0019] This disclosure provides a system for counting the number of workers in a vessel's work area based on contactless check-in technology. It uses RFID radio frequency identification devices to form a group of card readers that can identify the direction of entry and exit, and determines the number of workers on each vessel by binding the vessel relationships.

[0020] In one exemplary implementation, the ship distribution scenario is as follows: Figure 1 The exemplary employee counting system according to this disclosure is shown in the attached figure. Figure 2 As shown, it mainly includes:

[0021] (1) RFID tags are worn by operators. The data in the tags includes: employee ID information and equipment number.

[0022] Preferably, each worker wears an RFID tag consisting of a first RFID tag and a second RFID tag, which are symmetrically affixed to the inside of the worker's safety helmet.

[0023] (2) Identification equipment group, each identification equipment group includes at least two RFID radio frequency identification devices with network transmission function, which are installed at the head and stern of the boarding ladder of each working vessel or the boarding ladder between vessels, and are used to read the RFID tags worn by the workers when they pass by, and transmit the data in the tags to the data acquisition and processing module through the network transmission function.

[0024] Preferably, each identification device group includes three RFID radio frequency identification devices with network transmission capabilities, which are evenly installed at the head, middle and stern positions of the boarding ladder of each working vessel or the passage ladder between vessels.

[0025] Preferably, RFID radio frequency identification devices are equipped with 4G and / or 5G network transmission modules.

[0026] (3) Data acquisition and processing module, used to collect and process the received data, and determine whether the operator enters or leaves a vessel according to the order in which the operator triggers the identification device in the same identification device group, and update the number of operators on each vessel.

[0027] (4) Preferably, the system also includes a display terminal for dynamically displaying the location of the operators and the specific number of operators on each vessel; specifically including: a computer terminal and a mobile device terminal, which respectively provide a web display page and a mobile display page.

[0028] Furthermore, this embodiment is implemented through the following technical solutions, including system construction steps and personnel location update steps;

[0029] The system construction steps include the following sub-steps:

[0030] Step 1: Use an RFID tag writing device to write the employee's employee ID information into the RFID tag, and then affix the RFID tag to the worker's safety helmet; two tags per person, affixed symmetrically on the left and right sides;

[0031] Step 2: Configure the device group on the software platform, forming an identification device group (hereinafter referred to as the identification device group) consisting of three RFID radio frequency identification devices with 4G network transmission capabilities. The devices within the group are labeled A, B, and C to indicate their actual installation order. Configure the 4G network reporting IP and port for each reader device using the host computer software. Install one device group on each fixed boarding and transfer ladder of each vessel at the dock, placing them at the head, tail, and middle positions of the ladder, ensuring the three readers are evenly distributed. Adjust the orientation of the readers to ensure that safety helmets appear within the reader's detection range when employees pass by.

[0032] Step 3: Deploy system software on the server to collect and process the data reported by the equipment group, determine the real-time location of employees based on the personnel location update steps, and display it on the software platform.

[0033] Specifically, it includes the following sub-steps:

[0034] Step 3.1: When the RFID radio frequency identification device detects the RFID tag, it reports the employee ID information in the tag and the device's own device number to the server via the 4G network.

[0035] Step 3.2: The server records the personnel's specific information based on the uploaded employee ID, and finds the equipment group and its order within the group by the equipment number. The personnel information, equipment information, and the current server time are combined to form a detection record and saved to the database.

[0036] Step 3.3: Determine the employee's latest location based on the order in which the employee triggers the card readers in the same equipment group. Set a maximum boarding time based on the length of the boarding ladder and the employee's walking speed. Only detection records within the maximum boarding time range can be used to determine the employee's location. For example, if an employee consecutively triggers multiple card readers in a fixed boarding ladder within the maximum boarding time, and the triggering order is from the dock towards the first-level ship, then the employee's latest location can be determined to be on the corresponding first-level ship.

[0037] The above technical solutions are merely exemplary embodiments of this utility model. For those skilled in the art, based on the application methods and principles disclosed in this utility model, it is easy to make various types of improvements or modifications, and not limited to the methods described in the specific embodiments of this utility model. Therefore, the methods described above are only preferred and not restrictive.
