Description

Technical Field

[0001] This application relates to the field of engineering construction, and in particular to a method, system, access control system and safety helmet for construction site safety management. Background Technology

[0002] Construction safety is of paramount importance. Ensuring construction safety is a consensus in the engineering field and an inescapable responsibility for both construction and supervision parties. Therefore, almost every construction site explicitly requires the full and correct wearing of protective equipment according to the construction scenario. However, in actual construction, due to insufficient safety awareness among construction workers, accidents often occur due to the failure to wear protective equipment or incomplete wearing of protective equipment, which has a significant impact on the personal safety of construction workers and the progress of construction. Summary of the Invention

[0003] To avoid safety accidents caused by insufficient protective equipment worn by construction workers, this application provides a construction site safety management method, system, access control system, and safety helmet.

[0004] Firstly, this application provides a construction site safety management method applied to an access control system, the construction site safety management method comprising:

[0005] Receive entry access requests from construction personnel, the entry access requests being used by the construction personnel to request entry into the construction site through the access control system;

[0006] A protection query request is sent to the associated safety helmet of the construction worker. The protection query request is used to request the associated safety helmet to read the radio frequency tag on the protective equipment worn by the construction worker through radio frequency identification in order to determine the protective equipment wearing status of the construction worker. The radio frequency tag records the identification information of the protective equipment that is uniquely associated with the radio frequency tag.

[0007] Receive the protection query response from the associated safety helmet based on the protection query request;

[0008] The entry access request is processed based on the protection query response.

[0009] By adopting the above technical solution, after construction workers need to enter the construction site and send an access request to the site's access control system, the access control system works in conjunction with the worker's safety helmet to allow the helmet to read the RFID tags on the worker's protective gear using radio frequency identification (RFID) technology. This allows the system to understand the worker's current protective gear wearing status and process the access request based on that status. Based on the solution provided in this application, the access control system determines whether a worker can enter the construction site based on their protective gear wearing status. This prevents workers with inadequate protective gear from entering, thereby reducing safety hazards caused by non-compliant protective gear wearing and ensuring the personal safety of construction workers. Furthermore, safety helmets are essential protective gear that everyone must use when entering the construction site; they are the most basic and common protective equipment. By placing the RFID reader on the safety helmet, construction workers are not required to carry separate RFID readers, reducing their burden while ensuring that the RFID reader can correctly read the RFID tags on other protective gear already worn by the worker.

[0010] Optionally, the protection query response includes identification information of the protective equipment already worn;

[0011] After receiving the construction personnel's request for access to the site, the construction site safety management method further includes:

[0012] The construction personnel are identified based on the access request;

[0013] The necessary protective equipment for the construction personnel is determined based on the identity recognition results. The necessary protective equipment is determined based on the current target construction scenario of the construction personnel. The target construction scenario is the scenario in which the construction personnel intend to work after entering the construction site.

[0014] The process of handling the access request based on the protection query response includes:

[0015] The protective equipment already worn is determined based on the response to the protection query.

[0016] The worn protective equipment is compared with the necessary protective equipment to determine whether the worn protective equipment matches the necessary protective equipment. Matching the worn protective equipment with the necessary protective equipment means that the worn protective equipment includes all of the necessary protective equipment.

[0017] If the protective equipment already worn does not match the necessary protective equipment, the request for entry shall be denied.

[0018] By adopting the above technical solution, after receiving an entry request from construction personnel, the access control system will also identify the personnel and determine their current necessary protective equipment based on the identification results. Considering that even within the same construction site, different construction scenarios have different protection requirements for construction personnel, this embodiment determines the necessary protective equipment corresponding to the construction personnel based on their target construction scenario. Furthermore, it compares the necessary protective equipment with the personnel's currently worn protective equipment to determine whether the personnel's protective equipment is compliant. If the worn protective equipment does not match the necessary protective equipment, the personnel's entry request is rejected. This allows for the use of different regulatory standards to monitor the wearing of protective equipment by construction personnel in different construction scenarios, achieving a personalized regulatory solution at the construction scenario level and enhancing the flexibility of construction site safety management. Furthermore, the access control system determines the necessary protective equipment, obtains the comparison results between the necessary protective equipment and the protective equipment already worn, and processes the construction personnel's entry and passage requests based on the comparison results. The safety helmet only needs to provide a protection query response that can reflect that the protective equipment is being worn. This reduces the functional requirements of the safety helmet and can reduce the cost of the safety helmet.

[0019] Optionally, determining the necessary protective equipment for the construction worker based on the identity recognition result includes:

[0020] The system receives task allocation information sent by the construction task platform, wherein the task allocation information contains the mapping relationship between the construction personnel and the task.

[0021] The current target construction scenario of the construction personnel is determined based on the identity recognition result and the task allocation information.

[0022] Query the necessary protective equipment corresponding to the target construction scenario.

[0023] Secondly, this application provides a construction site safety management method applied to safety helmets, the construction site safety management method comprising:

[0024] The access control system receives a protection query request for the associated construction personnel after receiving their access request. The associated construction personnel are those wearing the safety helmet. The access request is used by the associated construction personnel to request access to the construction site through the access control system.

[0025] According to the protection query request, the RFID tags on the protective equipment worn by the associated construction personnel are read, and the RFID tags record the identification information of the protective equipment that is uniquely associated with the RFID tag;

[0026] A protection query response is generated based on the read identification information;

[0027] The protective query response is sent to the access control system so that the access control system can process the entry request based on the protective equipment worn by the associated construction personnel.

[0028] By adopting the above technical solution, construction workers associated with safety helmets will send an entry request to the access control system when they need to enter the construction site. Upon receiving the entry request, the access control system works in conjunction with the safety helmet to read the RFID tags on the protective gear worn by the worker using radio frequency identification (RFID) technology. This allows the system to understand the worker's current protective gear wearing status and process the entry request accordingly. Based on the solution provided in this application, the access control system determines whether a worker can enter the construction site based on their protective gear wearing status. This prevents workers with inadequate protective gear from entering the construction site, thereby reducing safety hazards caused by non-compliant protective gear wearing and ensuring the personal safety of construction workers. Furthermore, safety helmets are essential protective gear for everyone entering the construction site; they are the most basic and common protective equipment. By placing the RFID reader on the safety helmet, construction workers are not required to carry separate RFID readers, reducing their burden while ensuring that the RFID reader can correctly read the RFID tags on other protective gear already worn by the worker.

[0029] Optionally, the construction site safety management method further includes:

[0030] The necessary protective equipment for the associated construction personnel is determined based on the current target construction scenario of the associated construction personnel. The target construction scenario is the scenario in which the construction personnel intend to work after entering the construction site.

[0031] The step of generating a protection query response based on the read identification information includes:

[0032] The currently worn protective equipment of the associated construction personnel is determined based on the read identification information;

[0033] The comparison result is obtained by comparing the worn protective equipment with the necessary protective equipment. The comparison result indicates whether the worn protective equipment matches the necessary protective equipment. Matching the worn protective equipment with the necessary protective equipment means that the worn protective equipment includes all of the necessary protective equipment.

[0034] Generate the protection query response carrying the comparison results.

[0035] By adopting the above technical solution, the safety helmet also determines the necessary protective equipment for the associated construction personnel. Considering that even within the same construction site, different construction scenarios have different protection requirements for construction personnel, this embodiment of the application determines the necessary protective equipment for the associated construction personnel based on the target construction scenario, and compares the necessary protective equipment with the currently worn protective equipment of the associated construction personnel. It obtains a comparison result that reflects whether the associated construction personnel's protective equipment wearing is compliant, and then returns the comparison result to the access control system in the protection query response. The access control system then processes the associated construction personnel's entry request based on the comparison result. This allows for the use of different regulatory standards to monitor the protective equipment wearing status of construction personnel in different construction scenarios, achieving a personalized regulatory solution at the construction scenario level, and enhancing the flexibility of the construction site safety management solution. Furthermore, by having the safety helmet determine the necessary protective equipment and obtain the comparison result between the necessary protective equipment and the currently worn protective equipment, the access control system only needs to process the construction personnel's entry request based on the comparison result. This reduces the burden on the access control system, especially in scenarios where a large number of construction personnel request entry to the construction site at the same time.

[0036] Optionally, the construction site safety management method further includes:

[0037] After the associated construction personnel enter the construction site through the access control, the sensor detects whether the safety helmet is being worn.

[0038] If the safety helmet is not being worn, an alarm will be triggered, and the situation of the safety helmet not being worn will be recorded in the monitoring record for the associated construction personnel.

[0039] When the safety helmet is in the wearing state, the radio frequency tag is read in real time to determine the current protective equipment being worn; the worn protective equipment is compared to determine whether it matches the necessary protective equipment; if the worn protective equipment does not match the necessary protective equipment, an alarm is issued and the mismatch is recorded in the monitoring record.

[0040] By adopting the above technical solution, after the associated construction personnel enter the construction site, the safety helmet will further monitor whether it is being worn. If it is not being worn, an alarm will be issued and the situation will be recorded in the monitoring record of the associated construction unit. This can reduce the possibility that the associated construction personnel will remove their safety helmets after passing through the access control. If the safety helmet is confirmed to be worn correctly, the safety helmet will further use an RFID reader to read the RFID tags on the associated construction personnel's already worn protective equipment in real time, and compare the necessary protective equipment with the already worn protective equipment to determine if they match. If they do not match, an alarm will be issued and the situation will be recorded in the monitoring record. This can further reduce the possibility that the associated construction personnel will remove their protective equipment after passing through the access control system, thereby improving construction safety.

[0041] Optionally, before receiving the protection query request, the construction site safety management method further includes:

[0042] Collect the biometric information of the associated construction personnel;

[0043] The identities of the associated construction personnel are verified in a legitimate biometric database based on the biometric information.

[0044] If identity verification is successful, an entry access request is sent to the access control system; if identity verification fails, an alarm request is sent to the access control system.

[0045] By adopting the above technical solution, before associated construction personnel enter the construction site, the safety helmet collects the biometric information of the personnel and verifies their legitimacy by identifying them in a legitimate biometric database. The safety helmet only sends an entry request to the access control system if the identification of the associated construction personnel is successful. Conversely, if the identification of the associated construction personnel fails and they are determined to be unauthorized personnel, the safety helmet will not send an entry request to the access control system but will instead send an alarm request. This solution ensures that unauthorized personnel have no opportunity to apply for entry to the construction site, further enhancing the safety of life and property at the construction site.

[0046] Thirdly, this application provides an access control system, including a first processor, a first memory, an electric door lock, a first communication unit, and a first communication bus. The first communication bus is communicatively connected to the first processor, the first memory, the electric door lock, and the first communication unit. The first memory stores a first construction site safety management program, which can be executed by the first processor to implement the construction site safety management method described in any one of the first aspects.

[0047] By adopting the above technical solution, after construction workers need to enter the construction site and send an access request to the site's access control system, the access control system works in conjunction with the worker's safety helmet to allow the helmet to read the RFID tags on the worker's protective gear using radio frequency identification (RFID) technology. This allows the system to understand the worker's current protective gear wearing status and process the access request based on that status. Based on the solution provided in this application, the access control system determines whether a worker can enter the construction site based on their protective gear wearing status. This prevents workers with inadequate protective gear from entering, thereby reducing safety hazards caused by non-compliant protective gear wearing and ensuring the personal safety of construction workers. Furthermore, safety helmets are essential protective gear that everyone must use when entering the construction site; they are the most basic and common protective equipment. By placing the RFID reader on the safety helmet, construction workers are not required to carry separate RFID readers, reducing their burden while ensuring that the RFID reader can correctly read the RFID tags on other protective gear already worn by the worker.

[0048] Fourthly, this application also provides a safety helmet, including a second processor, a second memory, an RFID card reader, a second communication unit, and a second communication bus. The second communication bus is communicatively connected to the second processor, the second memory, the RFID card reader, and the second communication unit. The second memory stores a second construction site safety management program, which can be executed by the second processor to implement the construction site safety management method described in any one of the second aspects above.

[0049] By adopting the above technical solution, construction workers associated with safety helmets will send an entry request to the access control system when they need to enter the construction site. Upon receiving the entry request, the access control system works in conjunction with the safety helmet to read the RFID tags on the protective gear worn by the worker using radio frequency identification (RFID) technology. This allows the system to understand the worker's current protective gear wearing status and process the entry request accordingly. Based on the solution provided in this application, the access control system determines whether a worker can enter the construction site based on their protective gear wearing status. This prevents workers with inadequate protective gear from entering the construction site, thereby reducing safety hazards caused by non-compliant protective gear wearing and ensuring the personal safety of construction workers. Furthermore, safety helmets are essential protective gear for everyone entering the construction site; they are the most basic and common protective equipment. By placing the RFID reader on the safety helmet, construction workers are not required to carry separate RFID readers, reducing their burden while ensuring that the RFID reader can correctly read the RFID tags on other protective gear already worn by the worker.

[0050] Fifthly, this application also provides a construction site safety management system, including the aforementioned access control system and multiple protective devices, the multiple protective devices including multiple aforementioned safety helmets and multiple non-helmet protective devices equipped with RFID tags, the non-helmet protective devices being protective devices other than the safety helmets; the access control system is communicatively connected to the safety helmets, the RFID tags record identification information of the protective devices uniquely corresponding to the RFID tags, and the RFID tags can be read by the RFID reader in the safety helmets.

[0051] In summary, this application includes at least the following beneficial technical effects:

[0052] 1. The access control system determines whether a construction worker can enter the construction site based on the protective equipment they are wearing. This can prevent construction workers who are not wearing protective equipment properly from entering the construction site, thereby reducing safety hazards caused by non-compliance with protective equipment and ensuring the personal safety of construction workers.

[0053] 2. By mounting the RFID reader on the safety helmet, construction workers are no longer required to carry an additional RFID reader. This reduces the burden on construction workers and ensures that the RFID reader can read the RFID tags on other protective equipment worn by construction workers. Attached Figure Description

Detailed Implementation

[0067] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0068] To reduce safety risks caused by construction workers not wearing protective equipment as required, improve construction safety, and protect the lives of construction workers, this application provides a construction site safety management system 10. Please refer to [link to relevant documentation]. Figure 1 The construction site safety management system 10 includes an access control system 20 and multiple protective equipment. The access control system 20 controls the door locks at the construction site and manages the access of construction personnel to and from the site. The protective equipment in this application refers to wearable protective equipment and does not include safety nets, protective air cushions, or other facilities deployed independently of construction personnel. The multiple protective equipment includes multiple safety helmets 30 (…). Figure 1 Only one of the multiple safety helmets 30 is shown in the image, as well as multiple non-helmet protective devices 40 other than the safety helmet 30. Figure 1 Only one of the multiple non-helmet protective devices 40 is shown in the image.

[0069] The safety helmet 30 is the most common, basic, and widely used type of protective equipment. It communicates with the access control system 20. Besides the safety helmet 30, protective equipment also includes non-helmet protective equipment 40 such as face protection, hearing protection, protective shoes, protective gloves, protective clothing, and fall protection. Face protection includes respiratory protection, such as respirators and dust masks. It can also include eye protection, such as goggles, which are suitable for construction sites with glaring light, such as welding or furnace work, or where harmful chemicals are present. Hearing protection is suitable for noisy construction sites and includes earmuffs and earplugs. Protective shoes are categorized into impact-resistant shoes, insulating shoes, anti-static shoes, acid and alkali-resistant shoes, oil-resistant shoes, and non-slip shoes. Protective gloves include acid and alkali-resistant gloves, electrical insulating gloves, welding gloves, X-ray-resistant gloves, and asbestos gloves. Protective clothing can be divided into special protective clothing and general work clothes. Fall protection equipment is suitable for construction sites where work is being done at heights, and includes safety belts and safety ropes.

[0070] The safety helmet 30 is equipped with an RFID reader, while the non-helmet protective gear 40 is equipped with RFID tags. The RFID reader can read RFID tags within a preset range centered on the safety helmet 30, thereby obtaining the information recorded in the RFID tags. In some examples of this embodiment, the RFID reader's RFID range can be set to ensure that the RFID reader normally only reads RFID tags around the construction worker wearing the safety helmet 30. In some examples, RFID tags are only located on the non-helmet protective gear 40; in other examples, RFID tags are located on both the non-helmet protective gear 40 and the safety helmet 30. Because each RFID tag records the identification information of the protective gear uniquely corresponding to that RFID tag, and the RFID reader is located on the safety helmet 30, the construction site safety management system 10 can determine all the protective gear worn by the construction worker based on the identification information read by the RFID reader, regardless of whether the safety helmet 30 has RFID tags.

[0071] In some examples, the identification information recorded in the RFID tag is information that can uniquely distinguish a piece of protective equipment within the entire construction site (including the construction site itself and associated rest areas). For example, each piece of protective equipment within the construction site has a unique identification code, which can uniquely identify a piece of protective equipment. It is understood that the purpose of this embodiment is to ensure that construction workers wear complete protective equipment through monitoring, such as requiring them to wear insulated shoes and gloves. If the RFID tag only records the unique identification code of the protective equipment, then the construction site safety management system 10 also needs to maintain a mapping relationship between the unique identification code and the type of protective equipment. This is necessary to query and determine which types of protective equipment the construction worker is wearing based on the identification information read by the RFID reader. It is understood that in the above examples, it is sufficient to ensure that the construction worker wears insulated shoes and gloves; which pair of insulated gloves and which pair of insulated shoes the worker is wearing are details that do not need to be considered. Therefore, in some examples, the identification information recorded in the RFID tag includes the type information of the corresponding protective equipment. The identification information read by the RFID reader can directly determine what types of protective equipment the construction workers are wearing.

[0072] The following is combined Figure 2 and Figure 3 The hardware structures of the aforementioned access control system 20 and safety helmet 30 are described separately:

[0073] First, please see Figure 2The access control system 20 includes a first processor 21, a first memory 22, an electric door lock 23, a first communication unit 24, and a first communication bus 25. The first processor 21, first memory 22, electric door lock 23, and first communication unit 24 are all connected to the first communication bus 25. Based on the first communication bus 25, the first memory 22, electric door lock 23, and first communication unit 24 can communicate with the first processor 21 respectively. The electric door lock 23 can unlock or lock under the control of the first processor 21. The first memory 22 can store several computer programs, each of which can be read, compiled, and executed by the first processor 21 to implement the corresponding method flow. The first communication unit 24 is used to realize external communication of the access control system 20. For example, in this example, the access control system 20 communicates with the safety helmet 30 through the first communication unit 24. The first communication unit 24 can be a wired communication unit or a wireless communication unit, such as a radio frequency unit, a WiFi module, or a Bluetooth module.

[0074] Helmet 30 has a helmet body; please also refer to [other details]. Figure 3 The safety helmet 30 also includes a second processor 31, a second memory 32, an RFID reader 33, a second communication unit 34, and a second communication bus 35. The helmet body serves as a carrier, supporting the second processor 31, second memory 32, RFID reader 33, second communication unit 34, and second communication bus 35. All four components—second processor 31, second memory 32, RFID reader 33, and second communication unit 34—are connected to the second communication bus 35. Through the second communication bus 35, the second processor 31 can communicate with the second memory 32, RFID reader 33, and second communication unit 34 respectively. The second memory 32 stores several computer programs, each of which can be read, compiled, and executed by the second processor 31 to implement a corresponding method flow. The second communication unit 34 can communicate with the access control system 20. In this embodiment, the second communication unit 34 supports wireless communication, allowing construction workers to move flexibly and freely while wearing the safety helmet 30. The RFID reader 33 can read RFID tags based on Radio Frequency Identification (RFID).

[0075] Based on the aforementioned construction site safety management system 10, this application also provides a construction site safety management method, please refer to [link to relevant documentation]. Figure 4 The interactive flowchart of this construction site safety management method is shown below:

[0076] S402: The access control system receives entry requests from construction personnel.

[0077] When construction workers need to enter the construction site from the outside, they will send an entry request to the access control system 20. The entry request is used to request entry into the construction site from the access control system 20. In some examples of this embodiment, the entry request can be sent by the construction workers through the physical button or the touch screen of the access control system 20. In other examples, the entry request can also be sent through communication with the access control system 20 via other facilities. For example, the construction workers can use a handheld Integrated Circuit Card (IC card) to swipe on the card reader of the access control system 20 to send the entry request. Alternatively, the construction workers can also send the entry request to the access control system 20 through their safety helmet 30.

[0078] S404: The access control system sends a protection query request to the construction worker's associated safety helmet.

[0079] In this embodiment, construction workers must wear safety helmets 30 to enter the construction site. By wearing safety helmets 30, construction workers are associated with safety helmets 30. For a construction worker, the safety helmet 30 they wear is their "associated safety helmet," and correspondingly, for that safety helmet 30, the corresponding construction worker is their "associated construction worker." After receiving an entry request from any construction worker, the access control system 20 can send a protection query request to the construction worker's associated safety helmet. The protection query request is used to request the safety helmet 30 to read the RFID tag on the protective equipment (hereinafter referred to as "wearing protective equipment") already worn by the construction worker based on radio frequency identification.

[0080] S406: Safety helmets read the radio frequency tags on the protective equipment worn by the associated construction workers based on the protection query request.

[0081] After receiving a protection query request from the access control system 20, the safety helmet 30 starts the radio frequency tag reading operation, reads the radio frequency tags within its radio frequency identification range, and obtains the identification information recorded in these radio frequency tags.

[0082] S408: The safety helmet generates a protection query response based on the read identification information.

[0083] In some examples of this embodiment, after the RFID reader 33 reads the identification information from the RFID tag, the safety helmet 30 can directly generate a protection query response based on the identification information. In these examples, the generated protection query response includes the identification information of each non-helmet protective device 40. In other examples, the safety helmet 30 can first process the read identification information and then generate a protection query response based on the processing result. In these examples, the generated protection query response may not contain the identification information read by the RFID reader 33. It is understood that the types of information contained in the protection query response are different in different examples, but these protection query responses can all characterize the current protective equipment worn by the associated construction personnel.

[0084] S410: The safety helmet sends the protection query response to the access control system.

[0085] After generating the protection query response, the safety helmet 30 can send the protection query response to the access control system 20, so that the access control system 20 can process the entry and passage requests of the associated construction personnel based on the protection query response.

[0086] S412: The access control system processes entry requests based on the protection query response.

[0087] After receiving the protection query response, the access control system 20 can process the worker's entry request based on the protective equipment currently being worn by the worker as reflected in the response. Undoubtedly, based on the protection query response, the access control system 20 can determine whether the worker's current protective equipment is compliant. Compliance of the worker's current protective equipment is a necessary condition for the access control system 20 to allow the worker to enter the construction site, but it is not necessarily the only necessary condition (for example, in some examples, the access control system 20 may need to further verify other conditions of the worker). Therefore, if the access control system 20 determines that the worker's current protective equipment is non-compliant, it can refuse the worker's entry request; however, if it determines that the worker's current protective equipment is compliant, there will be situations where the access control system 20 approves the entry request in some examples and disapproves it in others.

[0088] It is understandable that in some large construction sites, at least two different construction scenarios may coexist. For example, in a building construction site, electrical construction, welding, and high-altitude construction scenarios may coexist. The protective requirements for workers entering these scenarios may differ. For instance, electrical and welding scenarios may require workers to wear insulated shoes and gloves, welding scenarios require face shields, and high-altitude construction scenarios require non-slip shoes and safety ropes. In this situation, the access control system 20 is not suitable for using the same protective gear standards to determine the entry requests of workers in different scenarios. Therefore, in some examples of this embodiment, the construction site safety management system 10 can assess whether the protective gear worn by a worker is compliant and whether the worker can be allowed to enter the construction site based on the specific construction scenario. The following will combine... Figure 5 The interactive flowchart shown illustrates another construction site safety management method provided in this application embodiment:

[0089] S502: The access control system receives entry requests from construction personnel.

[0090] S504: The access control system sends a protection query request to the construction worker's associated safety helmet.

[0091] S506: Safety helmets read the radio frequency tags on the protective equipment worn by the associated construction workers based on the protection query request.

[0092] S508: The access control system identifies construction personnel based on their entry requests and determines the necessary protective equipment for each personnel based on the identification results.

[0093] The access control system 20 can identify construction workers based on their entry requests, determining which of them is a legitimate construction worker. Further, after obtaining the identification result, the access control system 20 can determine the necessary protective equipment for that worker. Necessary protective equipment refers to the protective gear required for the worker to enter their corresponding construction scene. In this embodiment, the scene where the worker will work after entering the construction site is recorded as the worker's "target construction scene." Therefore, the necessary protective equipment is the protective gear that the worker must wear to enter the target construction scene. Thus, the determination of necessary protective equipment can be based on the worker's corresponding target construction scene. In some examples, the access control system 20 is communicatively connected to the construction operation task platform 50 at the construction site; please refer to [link to relevant documentation]. Figure 6As shown, the construction task platform 50 is used to assign tasks to construction workers. Therefore, the construction task platform 50 records the current tasks of each construction worker. The access control system 20 communicates with the construction task platform 50 and can obtain task assignment information containing the mapping relationship between construction workers and tasks from the construction task platform 50. Then, it can determine the current target construction scene of the construction worker based on the task assignment information. Subsequently, the access control system 20 determines the necessary protective equipment corresponding to the target construction scene of the construction worker based on the mapping relationship between the construction scene and the necessary protective equipment.

[0094] In other examples, please combine Figure 7 , Figure 7 The diagram shows the interaction process between the access control system 20 and the construction operation task platform 50:

[0095] S702: The access control system will send the identification results of construction personnel to the construction operation task platform.

[0096] S704: The construction task platform determines the target construction scenario for construction personnel based on the identity recognition results and task allocation information.

[0097] S706: The construction operation task platform determines the necessary protective equipment for construction personnel based on the target construction scenario.

[0098] S708: The construction operation task platform sends the type information of necessary protective equipment to the access control system.

[0099] After obtaining the identification results for the construction personnel, the access control system 20 can transmit the identification results to the construction task platform 50. The construction task platform 50 can determine the corresponding task for the construction personnel based on the mapping relationship between the construction personnel and the task. The construction task platform 50 can first determine the target construction scene for the construction personnel based on the task, and then determine the necessary protective equipment based on the target construction scene. Subsequently, the type information of the necessary protective equipment is fed back to the access control system 20.

[0100] In some other examples, after the construction task platform 50 determines the current target construction scenario of the construction personnel, it can directly feed back the information representing the target construction scenario to the access control system 20, which can then determine the necessary protective equipment based on the target construction scenario.

[0101] S510: The safety helmet generates a protection query response based on the read identification information.

[0102] After receiving a protection query request from the access control system 20, the safety helmet 30 will start radio frequency reading according to the protection query request, read the radio frequency tags on the protective equipment currently worn by the associated construction personnel, obtain the identification information in these radio frequency tags, and generate a protection query response based on the read identification information.

[0103] S512: The safety helmet sends the protection query response to the access control system.

[0104] After generating a protection query response carrying identification information of wearing protective equipment, the safety helmet 30 sends the protection query response to the access control system 20 through the communication channel between itself and the access control system 20 as a response to the protection query request of the access control system 20.

[0105] S514: The access control system determines the protective equipment currently worn by construction personnel based on the response to the protection query.

[0106] In some examples, the identification information carried in the protection query response received by the access control system 20 includes the type of protective equipment being worn. In this case, the access control system 20 can directly determine which protective equipment the construction worker is currently wearing based on the protection query response. In other examples, the identification information contained in the protection query response received by the access control system 20 is a unique identifier for the protective equipment being worn. In this case, the access control system 20 also needs to combine the mapping relationship between the unique identifier of the protective equipment and the type of protective equipment to determine the protective equipment being worn by the construction worker.

[0107] S516: Access control systems compare the protective gear already worn with the necessary protective gear.

[0108] The access control system 20 can determine the protective equipment currently worn by the construction worker based on the protection query response. Furthermore, it can determine the necessary protective equipment based on the worker's current target construction scenario. Subsequently, the access control system 20 can compare the worn protective equipment with the necessary protective equipment to determine if the worker's worn protective equipment matches the corresponding necessary protective equipment. In this embodiment, a match between the worn protective equipment and the necessary protective equipment means that the worn protective equipment includes all the necessary protective equipment. If the set of necessary protective equipment is denoted as S1, and the set of worn protective equipment is denoted as S2, then S1 should be a subset of S2.

[0109] S518: The access control system shall refuse entry requests if the protective equipment worn does not match the necessary protective equipment.

[0110] After determining the match between the worn protective equipment and the necessary protective equipment through comparison, the access control system 20 can process the construction personnel's entry request based on the comparison result. In some examples of this embodiment, if the access control system 20 determines that the worn protective equipment does not match the necessary protective equipment, the access control system 20 can directly refuse the construction personnel's entry request, thereby ensuring that construction personnel whose protective equipment is not up to standard cannot enter the construction site and eliminating safety hazards caused by inadequate protective equipment.

[0111] As described above, in this example, after receiving an entry request, the access control system 20 mainly performs two tasks: firstly, it uses a protection query request to determine the worker's existing protective equipment from the safety helmet 30; secondly, it determines the worker's current necessary protective equipment. These two processes can be performed simultaneously or sequentially. For example, in some examples, after receiving an entry request, the access control system 20 can first determine the worker's existing protective equipment and then determine the worker's current necessary protective equipment. In another example, the access control system 20 can first determine the worker's necessary protective equipment and then determine the worker's existing protective equipment.

[0112] exist Figure 5 In the example of the corresponding construction site safety management scheme, the safety helmet 30 only needs to activate RFID based on the protection query request from the access control system 20, and generate a protection query response based on the identification information read by RFID and send it to the access control system 20. The process of determining the necessary protective equipment for construction workers and comparing the necessary protective equipment with the already worn protective equipment is all completed by the access control system 20. In this example, the performance requirements for the safety helmet 30 are not high, thus reducing the cost of the safety helmet 30. However, relatively speaking, the processing burden on the access control system 20 will be relatively heavy. Therefore, this embodiment also provides another construction site safety management method, please refer to... Figure 8 The diagram shows the interactive flow of the construction site safety management method:

[0113] S802: The access control system receives entry requests from construction personnel.

[0114] In some examples of this embodiment, construction workers can send an entry request to the access control system 20 via their associated safety helmets. For instance, the safety helmet 30 can communicate with the access control system 20 via Near Field Communication (NFC) to send the worker's entry request to the access control system 20. This embodiment also provides a scheme for the safety helmet 30 to send an entry request to the access control system 20; please refer to [link to relevant documentation]. Figure 9 The flowchart shown is as follows:

[0115] S902: Safety helmets collect biometric information associated with construction workers.

[0116] In some examples of this embodiment, the safety helmet 30 can collect biometric information of the associated construction personnel. The safety helmet 30 can be equipped with at least one of a camera module and a fingerprint recognition module. The camera module can be used to collect fundus images and / or facial images of the associated construction personnel, thereby obtaining the iris features and / or facial features of the associated construction personnel. The fingerprint recognition module can collect the fingerprint features of the associated construction personnel.

[0117] S904: Safety helmets use biometric information to identify associated construction workers in a legitimate biometric database.

[0118] After collecting the biometric information of the associated construction personnel, the safety helmet 30 can match this biometric information with a legitimate biometric database to identify the personnel. If the biometric information of the associated construction personnel matches a biometric record in the legitimate database, the identification is successful, and the safety helmet 30 can also determine the specific identity information of the associated construction personnel. If the biometric information of the associated construction personnel does not match any biometric record in the legitimate biometric database, the identification fails.

[0119] S906: The safety helmet determines whether identity recognition is successful.

[0120] If the judgment result is yes, then execute S908; otherwise, execute S910.

[0121] S908: The safety helmet sends an entry access request to the access control system.

[0122] If the identification of the associated construction personnel is successful, the safety helmet 30 can generate an entry access request based on the determined identity information. The entry access request can directly include the identification result of the associated construction personnel. In this way, after the access control system 20 receives the entry access request, it does not need to identify the associated construction personnel through other means.

[0123] S910: The safety helmet sends an alarm request to the access control system.

[0124] If the identification of the associated construction personnel fails, the safety helmet 30 will refuse to send an entry request to the access control system 20. This prevents unauthorized personnel from entering the construction site, even if they are wearing the safety helmet 30 corresponding to the construction location. In some examples of this embodiment, if the safety helmet 30 fails to identify the associated construction personnel, it can also send an alarm request to the access control system 20. Upon receiving the alarm request, the access control system 20 will notify the security guard at the gate, who will then verify the situation on-site.

[0125] S804: The access control system sends a protection query request to the construction worker's associated safety helmet.

[0126] S806: Safety helmets read the radio frequency tags on the protective equipment worn by the associated construction workers based on the protection query request.

[0127] S808: The safety helmet determines the currently worn protective equipment of the associated construction worker based on the read identification information.

[0128] In this embodiment, after the safety helmet 30 reads the RFID tag on the worn protective gear via RFID, it directly determines the currently worn protective gear of the associated construction worker based on the read identification information. The process by which the safety helmet 30 determines the worn protective gear based on the identification information can be referred to the process by which the access control system 20 determines the worn protective gear based on the identification information, and will not be described in detail here.

[0129] S810: Safety helmets are the necessary protective equipment for construction workers.

[0130] In this embodiment, the safety helmet 30 needs to determine not only the protective equipment currently worn by the associated construction worker, but also the necessary protective equipment for that worker. In some examples, the safety helmet 30 can communicate with the construction task platform 50, such as... Figure 10As shown, considering the need for construction workers to move freely, in this example, the safety helmet 30 can communicate with the construction task platform 50 wirelessly, such as, but not limited to, Bluetooth, infrared, mobile cellular network-based, or ZigBee communication. Through this communication connection, the construction task platform 50 can distribute the work tasks of the construction workers to their associated safety helmets. In some examples, the safety helmet 30 is equipped with a human-machine interface unit, such as a display screen. The construction workers can then see what kind of work tasks the construction task platform 50 has assigned them through the display screen on their associated safety helmets and perform the tasks accordingly, eliminating the need for dedicated personnel to assign and communicate tasks. When determining the necessary protective equipment for the associated construction workers, the safety helmet 30 can interact with the construction task platform 50 to directly determine the necessary protective equipment from the platform, or obtain key information from the platform for determining the necessary protective equipment. For example, in one instance, for a construction worker, the construction task platform 50 can determine the worker's task assignment information and then identify the target construction scenario and necessary protective equipment. In other instances, the safety helmet 30 stores a mapping relationship between the task, the target construction scenario, and the necessary protective equipment. After the construction task platform 50 distributes the task to the safety helmet 30, the safety helmet 30 can determine the appropriate protective equipment by querying the mapping relationship between the task, the target construction scenario, and the necessary protective equipment.

[0131] S812: The safety helmet compares the already worn protective equipment with the necessary protective equipment to obtain the comparison result, and generates a protection query response based on the comparison result.

[0132] After determining the current protective equipment (PEG) and necessary PEG of the associated construction workers, the safety helmet 30 can compare the two to determine whether the PEG and PEG match. If the PEG does not include all the necessary PEG, then the PEG and PEG do not match. In this embodiment, the safety helmet 30 generates a protection query response based on the comparison result of the PEG and PEG. Therefore, based on the protection query response, it can be directly determined whether the current PEG worn by the construction workers is compliant.

[0133] S814: The safety helmet sends the protection query response to the access control system.

[0134] After generating a protective query response, the safety helmet 30 sends it to the access control system 20, so that the access control system 20 can process the access request of the associated construction personnel based on the wearing of protective equipment.

[0135] S816: The access control system shall refuse entry requests if the protective equipment worn does not match the necessary protective equipment.

[0136] Upon receiving the protection query response from the safety helmet 30, the access control system 20 can parse the response and determine the match between the worn protective equipment and the necessary protective equipment based on the parsing results. If the access control system 20 determines that the worn protective equipment does not match the necessary protective equipment, it can directly refuse the construction worker's entry request. If the access control system 20 determines that the worn protective equipment matches the necessary protective equipment, and the construction worker also meets other requirements for entering the construction site, it can allow the worker to pass.

[0137] Understandably, once workers enter the construction site through the access control system, the system's monitoring of their protective gear becomes ineffective. Workers may remove the gear due to the feeling of constraint, rendering the system meaningless and putting them back at a safety hazard. Therefore, this embodiment of the construction site safety management solution also provides a solution, which should be considered in conjunction with... Figure 11 The flowchart shown can be executed by the safety helmet 30.

[0138] S1102: After the associated construction personnel enter the construction site through the access control, the wearing status of the safety helmet is detected by the sensor.

[0139] In this embodiment, the safety helmet 30 is equipped with several sensors connected to the second communication bus 35, allowing it to transmit its collected sensor data to the second processor 31. The second processor 31 then determines the state of the safety helmet 30 based on the sensor data. In this embodiment, the sensors may include, but are not limited to, at least one of pressure sensors, gyroscopes, infrared sensors, and brightness sensors. The pressure sensor can be located inside the safety helmet 30, for example, on the side of the helmet 30 facing the wearer's head (e.g., the side band) and / or on the side of the helmet 30's cushioning pad facing the wearer's head. When the safety helmet 30 is worn by a construction worker, the worker's head will contact and be compressed against these areas of the helmet 30, thus detecting the pressure. Alternatively, the pressure sensor can also be located on the chin strap of the safety helmet 30. The infrared sensor can detect the presence of a human body through infrared sensing and can be located inside the safety helmet 30, i.e., on the side of the helmet 30 facing the wearer's body. A brightness sensor can detect ambient brightness. In some examples, the brightness sensor can be placed on the side of the helmet 30's cushioning pad facing the wearer. When the helmet 30 is worn, the brightness value detected by the brightness sensor is lower, while when the helmet 30 is removed, the brightness value detected by the brightness sensor may be higher. A gyroscope can detect the posture of the helmet 30. It is understood that each sensor has its limitations. Therefore, in this embodiment, to improve the accuracy of detecting the wearing status of the helmet 30, two or more sensors can be selected to be set on the helmet 30 simultaneously.

[0140] S1104: Determine whether the safety helmet is being worn.

[0141] If the judgment result is yes, then execute S1108; otherwise, execute S1106.

[0142] S1106: Issue an alarm and record the situation where the safety helmet is not being worn in the monitoring record for the relevant construction personnel.

[0143] If the second processor 31 determines through sensor detection that the safety helmet 30 is not currently being worn, the safety helmet 30 can issue an alarm. The alarm of the safety helmet 30 includes at least one of on-site alarms and remote alarms. On-site alarms refer to the safety helmet 30 issuing an alarm through its own human-machine interface unit, including playing an alarm bell or alarm voice through a speaker, or providing a visual alarm by illuminating or flashing an alarm light. It is understood that on-site alarms can also provide both audible and visual alarms simultaneously. Remote alarms refer to the safety helmet 30 transmitting alarm information to the control center at the construction site via the second communication unit 34, or sending alarm information to the supervisor's mobile phone, tablet, laptop, or other terminal device.

[0144] In addition to alerting construction workers when they remove their safety helmets 30, the safety helmet 30 can also record this information in the corresponding monitoring record of the construction worker. This allows the monitoring team to understand and evaluate the work of the construction workers based on the monitoring record and to correct any non-compliant behavior in a timely manner. In some examples of this embodiment, the monitoring record is stored in the second memory 32 of the safety helmet 30; however, the safety helmet 30 can transmit the monitoring record to the control center when needed. In other examples, the monitoring record can be maintained and updated by the control center. In these examples, the safety helmet 30 only needs to report the non-compliant behavior of the construction workers to the control center in a timely manner.

[0145] S1108: Reads RFID tags in real time to determine the current protective equipment being worn.

[0146] If the second processor 31 determines that the safety helmet 30 is being worn based on the sensor data, then the safety helmet 30 can further determine whether the non-helmet protective equipment 40 is still being worn by the construction worker: the second processor 31 can control the radio frequency reader 33 to perform radio frequency reading to read the identification information of the radio frequency tags within a preset range, thereby determining which protective equipment the associated construction worker is currently wearing (in fact, determining which protective equipment is within the preset range of the safety helmet 30; however, since the safety helmet 30 is being worn, if a piece of protective equipment is within the preset range of the safety helmet 30, it can be basically determined that the protective equipment is on the associated construction worker, i.e., being worn by the associated construction worker).

[0147] S1110: Compare and determine whether the protective equipment worn matches the necessary protective equipment.

[0148] After determining the protective equipment currently worn by the relevant construction personnel in real time, the safety helmet 30 can compare the worn protective equipment with the necessary protective equipment again to determine whether the two match. If the judgment result is no, S1112 is executed; otherwise, S1114 is executed.

[0149] S1112: Issue an alarm and record any discrepancies between the worn protective equipment and the necessary protective equipment in the monitoring log.

[0150] If it is determined that the protective equipment worn by the relevant construction personnel does not match the necessary protective equipment, it indicates that the personnel temporarily removed at least some of the necessary protective equipment after entering the construction site, and therefore an alarm needs to be issued. The alarm method is described above and will not be repeated here. Additionally, the safety helmet 30 will also record this mismatch between the worn protective equipment and the necessary protective equipment in the relevant construction personnel's monitoring record.

[0151] S1114: Monitor whether a new testing cycle has begun.

[0152] If the judgment result is yes, it means that a new round of testing is required. Therefore, the safety helmet 30 executes S1102. Otherwise, it continues to execute S1114 until a new testing cycle begins.

[0153] It is understood that both the first memory 22 in the access control system 20 and the second memory 32 in the safety helmet 30 can be used to store instructions, programs, code, code sets, or instruction sets. The first memory 22 may include a program storage area and a data storage area.

[0154] Both the first processor 21 and the second processor 31 may include one or more processing cores. The first processor 21 implements various functions on the access control system 20 side by running or executing instructions, programs, code sets, or instruction sets stored in the first memory 22 and calling data stored in the first memory 22. The second processor 31 implements various functions on the door safety helmet 30 side by running or executing instructions, programs, code sets, or instruction sets stored in the second memory 32 and calling data stored in the second memory 32.

The computer-readable storage medium stores at least one of a first construction site safety management program and a second construction site safety management program.
