Abstract
Description
Technical Field
[0001] This invention relates to the field of construction safety management technology, and in particular to a method for increasing the wearing rate of reflective vests and the carrying rate of essential items by construction workers. Background Technology
[0002] Reflective vests are essential protective equipment for construction workers at night or in low-visibility environments, and their proper wearing is directly related to their safety. Currently, the industry generally uses manual inspections or fixed camera monitoring to supervise the wearing of reflective vests, which has the following technical shortcomings:
[0003] 1. Passive supervision model is inefficient
[0004] The existing regulatory system relies heavily on manual spot checks or scheduled patrols, making it difficult to achieve 24 / 7 real-time monitoring. According to statistics from the Ministry of Housing and Urban-Rural Development, the rate of reflective vest wearing by construction workers under the traditional management model can fluctuate by ±37%, with violations increasing significantly during the midday shift handover period.
[0005] 2. Physical tags are easily misused.
[0006] Traditional RFID electronic tags mostly adopt an integrated design, which has management loopholes such as electronic tag lending and substitution. Some construction workers evade detection by sharing tag codes or temporarily borrowing other people's tags, resulting in a system misjudgment rate as high as 23%.
[0007] 3. Single dimension of identity authentication
[0008] Existing RFID technology can only achieve identification at the item level and cannot effectively distinguish the correspondence between "people and objects". When construction workers need to change their reflective vests due to job changes, the tag information needs to be updated simultaneously, which is a cumbersome process and prone to information lag.
[0009] 4. Insufficient environmental adaptability
[0010] Traditional RFID readers are affected by factors such as metal reflection and liquid absorption, limiting their effective identification distance to only 0.5 to 0.8 meters. In rainy, foggy weather or complex construction scenarios, signal attenuation often leads to missed detections.
[0011] The aforementioned technical bottlenecks make it difficult for existing safety management systems to meet the mandatory requirements of the Ministry of Housing and Urban-Rural Development's "Standard for Safety Inspection of Building Construction" (JGJ59-2024) regarding "full-time monitoring of protective equipment for special operations personnel". Summary of the Invention
[0012] Existing methods for monitoring the wearing of reflective vests and the carrying of essential items suffer from low efficiency, easy misuse of physical tags, limited identification dimensions, and insufficient environmental adaptability. The purpose of this invention is to provide a method based on split-type RFID tags, biometric identification, and periodic verification technology to improve the wearing rate of reflective vests and the carrying rate of essential items among construction workers, achieving accurate verification of these aspects.
[0013] The technical solution adopted by this invention to solve its technical problem is: a method for improving the wearing rate of reflective vests and the carrying rate of essential items by construction workers, the steps of which are as follows:
[0014] S1: Each construction worker entering the construction site is equipped with a set of wearable devices in advance. The wearable devices include a reflective vest, a split RFID tag, a wristband, and multiple conventional RFID tags. The split RFID tag consists of a first part and a second part. The first part of the split RFID tag is fixed in a designed position on the reflective vest. The construction worker wears the reflective vest. The second part is held by the construction worker and is pre-loaded with the personal identification information of the construction worker. A conventional RFID tag is set on each of the other essential items that the construction worker must carry. The conventional RFID tag is pre-loaded with the category identification information of the essential items. The construction worker wears a wristband, which is pre-loaded with the identification information of the construction worker. A split RFID reader is installed above the access control of the construction site to facilitate simultaneous identification with the facial recognition system. The facial recognition system is installed at the access control point.
[0015] S2: The back-end control system is connected to the separate RFID reader, facial recognition system, wristband, and access control system. When construction personnel enter or exit the access control system, the back-end control system compares the facial features transmitted by the facial recognition system with the database to identify the construction personnel to be allowed to pass. It then compares the identification information returned by the separate RFID reader with the identification information of the facial recognition system to determine whether to allow the construction personnel to pass. Within the construction site, the back-end control system compares the construction personnel information transmitted by the wristband with the information of the construction personnel associated with the reflective vest. If there is a discrepancy or the tag transmitted by the wristband is in an abnormal state, an alarm message is issued indicating that the reflective vest is not being worn correctly. The back-end control system also compares the construction personnel information transmitted by the wristband with the information on the types of essential items to determine whether the construction personnel are carrying any essential items other than the reflective vest. If there is a discrepancy or the information is in an abnormal state, an alarm message is issued indicating that all essential items are being carried, and the type of missing item is recorded.
[0016] This invention provides a method to improve the wearing rate of reflective vests and the carrying rate of essential items by construction workers. To prevent workers from entering the construction site without wearing reflective vests or carrying necessary items, a wearable device is attached to each worker at the construction site entrance and ensures that the device is carried throughout the site. The wearable device includes a reflective vest, a split-type RFID tag, a wristband, and multiple RFID chips. The first part of the split-type RFID tag is fixed to a designed position on the reflective vest, and the second part is pre-loaded with the worker's personal identification information and held by the worker. A regular RFID tag is attached to each of the worker's other essential items, pre-loaded with the item's category identification information. The worker's wristband is pre-loaded with their identification information. A split-type RFID reader and a facial recognition system are installed at the construction site entrance. The backend control system is connected to the RFID reader, facial recognition system, wristband, and access control system. The backend control system uses RFID... The reader reads the identification information of the person wearing the reflective vest and verifies with the facial recognition system whether the person wearing the reflective vest and the facial information read by the facial recognition system are the same person. If they are the same person, passage is granted. Within the construction site, the split RFID tag, regular RFID tag, and the wristband worn by the construction worker are linked to determine whether the split RFID tag on the reflective vest is in a normal state (e.g., not disassembled, not outside the recognition range) and to confirm whether the person entering the site is carrying necessary items. By setting the split RFID tag on the reflective vest, the construction worker must combine the second part, which stores the construction worker's information, with the first part fixed on the reflective vest and pass through the access control together. If the reflective vest needs to be replaced, the second part is removed from the slot of the first part and inserted into the slot of the first part on the reflective vest to be worn to reassemble a complete and identifiable split RFID tag. On this basis, the facial recognition system confirms whether the wearer is the holder of the second part, preventing construction workers from using the same RFID tag and increasing management difficulty. In summary, the method of the present invention for improving the wearing rate of reflective vests and the carrying rate of essential items by construction workers effectively solves the technical problem of dynamic binding of identity and equipment in construction scenarios by adopting multi-factor authentication technologies such as split RFID radio frequency tags, facial recognition systems, and wristband monitoring.
[0017] Furthermore, the method for determining the personnel to whom the reflective vest belongs includes the following steps: The first part of the split RFID radio frequency tag includes an antenna, a radio frequency module, a control module, and a power supply system; the second part includes a memory for storing the construction worker identification information of the holder; the first part is provided with a slot and fixed in the designed position of the reflective vest; the slot has a reserved interface for detachable connection with the second part; when the second part is inserted into the slot of the first part, the split RFID reader can read the construction worker information of the holder stored in the second part through the first part.
[0018] Furthermore, step S2 also includes: the wristband periodically interacts with the split RFID radio frequency tag and the conventional RFID tag, and uploads the collected identification information to the background control system via WIFI in the construction site. The wristband is equipped with a pulse monitoring system. In the construction site, the pulse monitoring system determines whether there is a split RFID radio frequency tag on the reflective vest within 2 meters of the wristband wearer, and determines whether the second part of the split RFID radio frequency tag and the wristband holder are the same person.
[0019] Furthermore, in step S2, the method for the face recognition system to confirm the person being scanned is as follows: the facial features of the construction worker to be passed are extracted by the camera of the access control system, and the background control system compares the facial feature information of the construction worker to be passed transmitted by the face recognition system with the construction worker information identified by the split RFID radio frequency tag on the reflective vest. If the two match, the worker is allowed to pass.
[0020] Furthermore, in step S2, the method for the wristband to confirm that the reflective vest is in a normal wearing state is as follows: Before the wristband is issued, the holder's personal identification information is pre-entered. After entering the construction site, the wristband interacts with the split RFID tag at a set interval and sends the received identification information to the background control system via the WIFI in the construction site. The background control system compares the personal identification information read by the wristband and the split RFID tag. If there is a mismatch, an alarm message is sent to the background control system indicating that the reflective vest is not worn correctly. If the wristband detects that the split RFID tag is in an abnormal state, it directly sends an alarm message to the background control system indicating that the reflective vest is not worn correctly.
[0021] Furthermore, in step S2, the method for confirming whether construction workers are carrying essential items at the construction site is as follows: Information pre-recorded in the conventional RFID tags fixed to the essential items is the category of the essential items. The wristband interacts with conventional RFID tags within a 2-meter range at set intervals and uploads the categories of all identified essential items to the backend control system. The backend control system compares the category information uploaded by the wristband with the categories of items the wristband holder is required to carry. If the category information uploaded by the wristband does not cover the categories of items the holder must carry, an alarm is issued indicating that the wristband holder is not carrying all required items, and the category information of the missing items is recorded.
[0022] Furthermore, in step S2, during a round of RFID information collection, uploading, and interaction with the back-end control system, if the wristband experiences a situation of no signal or no system response during a certain interaction with the back-end control system via WIFI, the collected information will be re-interacted with the back-end control system every 1 minute. After a successful interaction, the information upload for this round will stop. This process will be repeated until the construction personnel leave the construction site through the access control.
[0023] Furthermore, in step S2, if the wristband has not interacted with the back-end control system via WIFI within 30 minutes after the last interaction while the construction personnel are on the construction site, the back-end control system will issue an alarm stating "Wristband is offline". The on-site management personnel need to further investigate whether the following situations exist: the construction personnel have been in a location with poor WIFI signal for a long time, the construction personnel have left the site without passing the access control, or the wristband is not working properly.

[0036] Combination Figures 1 to 10 The method of the present invention for improving the wearing rate of reflective vests and the carrying rate of essential items by construction workers is described in the following steps:
[0037] S1: Each construction worker entering the construction site is equipped with a wearable device, which includes a reflective vest 5, a split RFID tag 10, a wristband, and multiple conventional RFID tags. The split RFID tag 10 consists of a first part 11 and a second part 15. Figure 1 , 2 In section 5, the first part 11 is represented by A, and the second part 15 is represented by B. The first part 11 of the split RFID radio frequency tag 10 is fixed at the designed position on the reflective vest 5. The construction worker wears the reflective vest 5. The second part 15 is held by the construction worker. The personal identification information of the construction worker is pre-entered into the second part 15. A regular RFID tag is set on other essential items carried by the construction worker. The regular RFID tag is pre-entered with the item category identification information of the essential items. The construction worker wears a wristband. The wristband is pre-entered with the identification information of the construction worker. A split RFID reader is installed above the access control of the construction site to facilitate simultaneous identification with the facial recognition system. The facial recognition system is installed at the access control.
[0038] S2: The back-end control system is connected to the split-type RFID reader, facial recognition system, wristband, and access control system. When construction personnel enter or exit the access control system, the back-end control system compares the facial features transmitted by the facial recognition system against its database to identify the personnel to be allowed passage. It then compares the identification information returned by the split-type RFID reader with the facial recognition information to determine whether to allow the personnel to pass. If the information is correct, the access control system opens and allows the personnel to pass. Within the construction site, the back-end control system monitors the wristbands within the construction site... The system compares the construction worker information sent by the wristband with the construction worker information associated with the reflective vest 5. If there is a discrepancy or the tag sent by the wristband is in an abnormal state, an alarm message is issued indicating that the reflective vest 5 is not being worn correctly. The back-end control system compares the construction worker information sent by the wristband in the construction site with the information on the types of essential items to determine whether the construction worker is carrying essential items other than the reflective vest 5. If there is a discrepancy or the system is in an abnormal state, an alarm message is issued indicating that essential items are not being carried, and the type of missing items is recorded.
[0039] This invention provides a method to improve the wearing rate of reflective vests 5 and the carrying rate of essential items by construction workers. To prevent construction workers from entering the construction site without wearing reflective vests 5 or carrying necessary items, the wearable device accompanies the worker from the entrance / exit gate, ensuring the device is carried throughout the site. The wearable device includes a reflective vest 5, a split-type RFID tag 10, a wristband, and multiple RFID chips. The first part 11 of the split-type RFID tag 10 is fixed to a designed position on the reflective vest 5, while the second part 15 is pre-loaded with the worker's personal identification information and held by the worker. A regular RFID tag is attached to each of the worker's other essential items, pre-loaded with the item category information. The wristband is pre-loaded with the worker's identification information. A split-type RFID reader and a facial recognition system are installed at the construction site entrance / exit. The backend control system is connected to the RFID reader, facial recognition system, wristband, and access control system. The backend control system reads the reflective vest information via the RFID reader. The system identifies the personnel on reflective vests 5 and verifies their facial information against the facial recognition system. If they match, passage is permitted. Within the construction site, the split-type RFID tag 10, conventional RFID tags, and the wristbands worn by construction workers are linked to determine if the split-type RFID tag 10 on the reflective vest 5 is in normal working order (e.g., not disassembled, not outside the recognition range) and confirms that personnel entering the site are carrying essential items. By setting the split-type RFID tag 10 on the reflective vest 5... Construction workers must combine the second part 15, which stores their personal information, with the first part 11 fixed to the reflective vest 5 to pass through the access control system. If the reflective vest 5 needs to be replaced, the second part 15 is removed from the slot 12 of the first part 11 and inserted into the slot 12 of the first part 11 on the new reflective vest 5 to reassemble a complete and identifiable split RFID tag 10. Furthermore, a facial recognition system confirms whether the wearer is the holder of the second part 15, preventing construction workers from using the same RFID tag and increasing management complexity. In summary, the method of this invention for improving the wearing rate of reflective vests 5 and the carrying rate of essential items by construction workers effectively solves the technical problem of dynamic binding of identity and equipment in construction scenarios by employing multi-factor authentication technologies such as split RFID tags 10, facial recognition systems, and wristband monitoring.
[0040] In step S2, the method for determining the person to whom the reflective vest 5 belongs is as follows:
[0041] like Figure 5As shown, the first part 11 of the split RFID radio frequency tag 10 includes an antenna, a radio frequency module, a control module, and a power supply system. The power supply system can be powered by a removable battery or solar power. The second part 15 only contains a memory for storing the construction worker identification information of the holder. The first part 11 has a slot 12 and is fixed to the design position of the reflective vest 5. The slot 12 has a reserved interface for detachable connection with the second part 15, which is convenient for the second part 15 to be removed at any time. However, when the second part 15 exists alone, it cannot be read by the split RFID reader. When the second part 15 is inserted into the slot 12 of the first part 11, the split RFID reader can read the construction worker information of the holder stored in the second part 15 through the first part 11.
[0042] Step S2 further includes: the wristband periodically interacts with the split RFID tag 10 and conventional RFID tags, and uploads the collected identification information to the backend control system via WIFI within the construction site. The wristband is equipped with a pulse monitoring system to ensure that the wristband is worn by the assigned construction worker, and not left idle in other locations along with the reflective vest 5. Within the construction site, the pulse monitoring system determines whether the split RFID tag 10 on the reflective vest 5 exists within 2 meters of the wristband wearer, and determines whether the second part 15 of the split RFID tag 10 and the wristband holder are the same person.
[0043] In step S2, the method for the face recognition system to confirm the person being scanned is as follows: the facial features of the construction personnel to be passed are extracted by the camera of the access control system, and the construction personnel to be passed are identified in this way. The background control system compares the facial feature information of the construction personnel to be passed transmitted by the face recognition system with the construction personnel information identified by the split RFID radio frequency tag 10 on the reflective vest 5. If the two match, the person is allowed to pass.
[0044] In step S2, the method for the wristband to confirm that the reflective vest 5 is in a normal wearing state is as follows: Before the wristband is issued, the holder's personal identification information is pre-entered. After entering the construction site, the wristband interacts with the split RFID radio frequency tag 10 every 5 minutes and sends the received identification information to the back-end control system via the WIFI in the construction site. The back-end control system compares the personal identification information read by the wristband and the split RFID radio frequency tag 10. If there is a mismatch, an alarm message is sent to the back-end control system indicating that the reflective vest 5 is not being worn correctly, providing a basis for management and response measures for the construction site management personnel. The wristband's interaction range is 2 meters. If the wristband detects that the split RFID radio frequency tag 10 is in an abnormal state, such as: the split RFID radio frequency tag 10 cannot be found, or the second part 15 tag has been removed, an alarm message is sent directly to the back-end control system indicating that the reflective vest 5 is not being worn correctly.
[0045] In step S2, the method for confirming whether construction workers at the construction site are carrying essential items is as follows:
[0046] The standard RFID tags attached to mandatory items are pre-loaded with information indicating the category of the mandatory items, such as safety helmets, safety shoes, and goggles. Due to different job types, the items that the personnel wearing the wristbands must bring to the site also vary. Every 5 minutes, the wristband interacts with standard RFID tags within a 2-meter range and uploads the categories of all identified mandatory items to the backend control system. The backend control system compares the item category information uploaded by the wristband with the categories of items the wristband holder is required to carry. If the category information uploaded by the wristband does not cover all the items the holder is required to carry, an alarm is issued indicating that the wristband holder is not carrying all required items, and the missing item categories are recorded for easy management at the construction site.
[0047] In this embodiment, the split-type RFID tag 10 must meet the international standard ISO / IEC 15693. This split-type RFID tag 10 can achieve a recognition distance of about 1 meter, and its harm to the human body is negligible. The first part 11 is fixed to the reflective vest 5, which can be located on the upper part such as the shoulder or chest pocket. The second part 15 is pre-loaded with the holder's identification information through an RFID information reader. It can be carried by the holder or left in the second part 15 year-round. In short, the function of the split-type RFID tag is to provide information containing the ownership information of the item.
[0048] Conventional RFID tags must meet the international standard ISO / IEC 15693, but unlike split-type RFID tags, conventional RFID tags are conventional integrated tags that only store the category information of fixed items and do not contain personnel information.
[0049] In step S2, due to the complex conditions at the construction site, the WIFI signal may be unstable. During a round of RFID information collection, uploading, and interaction with the backend control system, if the wristband experiences a signal loss or no system response during a particular interaction with the backend control system via WIFI, the collected information will be re-interacted with the backend control system every minute. After a successful interaction, the information upload for that round will stop. This "repeated attempt" action will be repeated a maximum of 3 times in each round. This is because the next round of information collection, uploading, and system interaction will begin at the 5th minute. This process will continue until the construction personnel leave the construction site through the access control.
[0050] In step S2, if the construction worker is on the construction site and the wristband has not interacted with the back-end control system via WIFI within 30 minutes after the last interaction, the back-end control system will issue an alarm with the message "Wristband is offline". The on-site management personnel need to further investigate whether the following situations exist: the construction worker has been in a location with poor WIFI signal for a long time, the construction worker has left the site without passing the access control, or the wristband is not working properly.
[0051] The above description is merely a description of preferred embodiments of the present invention and is not intended to limit the scope of the present invention in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the scope of the claims.
