Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, and in particular to a method and system for monitoring labor use at construction sites. Background Technology

[0002] With the rapid development of my country's construction industry, the scale of construction projects is constantly expanding, construction techniques are becoming increasingly complex, and the number of laborers on construction sites is also continuously increasing.

[0003] During construction, construction sites contain numerous high-risk areas, such as aerial work platforms, deep foundation pits, and electrical work areas. Current technology struggles to monitor in real-time whether workers are entering unauthorized areas, often relying on site management personnel for patrols and supervision. This results in long warning response times and an inability to promptly stop violations. Furthermore, traditional timekeeping methods, primarily paper-based clocking in or manual recording, are prone to omissions and errors, making it difficult to link time calculations to actual work completion and accurately reflect workers' workload, potentially leading to labor disputes. Summary of the Invention

[0004] The main objective of this invention is to propose a method and system for monitoring labor at construction sites, which aims to protect the safety of construction workers while accurately recording their workload.

[0005] To achieve the above objectives, the present invention proposes a method for monitoring labor use at construction sites, comprising the following steps: The data from the wearable terminal device of the construction worker is acquired, including the construction worker's identity information and location data. Obtain the work qualification list corresponding to the work process area; When the location data determines that the construction worker is located in the work process area, the identity information of the construction worker is verified against the work qualification list corresponding to the work process area; If the identity information of the construction worker is successfully verified against the work qualification list corresponding to the work process area, the construction worker is prompted to enter the work process area, and the actual working hours of the construction worker in the work process area are recorded; if the identity information of the construction worker fails to be verified against the work qualification list corresponding to the work process area, an alarm is triggered.

[0006] In one embodiment, before obtaining the work qualification list corresponding to the work process area, the labor monitoring method further includes: dividing the construction task into multiple work processes, physically delineating the construction site according to the multiple work processes to obtain multiple work process areas, and configuring corresponding work qualification lists for the multiple work process areas.

[0007] In one embodiment, the step of physically delineating the construction site into multiple process areas based on multiple processes, and configuring corresponding work qualification lists for the multiple process areas includes: establishing a BIM model based on a preset construction plan, dividing the spatial range of each process area in the BIM model according to the process, constructing an electronic fence based on the spatial range of each process area, and configuring corresponding work qualification lists for the electronic fence.

[0008] In one embodiment, the identity information of the construction personnel includes the construction personnel's work operation certificate number and their affiliated unit data.

[0009] In one embodiment, the labor monitoring method further includes: calculating the actual workload of the construction workers in the process area based on their actual working hours in the process area.

[0010] In one embodiment, the alarm triggering step includes at least one of the following: on-site audible and visual alarm, construction site broadcast prompt, and push alarm information to the wearable terminal device of construction personnel.

[0011] In one embodiment, the employment monitoring method further includes generating at least one of the following reports according to a preset cycle: an attendance report, a workload statistics report, an abnormal behavior report, and a qualification verification result report, based on the employment data collected in real time.

[0012] In one embodiment, a hash value is obtained by performing a hash operation on the attendance data in the attendance report, the actual working hours statistics in the workload statistics report, the abnormal behavior data in the abnormal behavior report, and the qualification verification results in the qualification verification result report. The attendance data, actual working hours statistics, abnormal behavior data, qualification verification results, and hash values ​​are then packaged into blocks according to timestamps and written to the blockchain. A digital signature and the writing time are recorded on the blockchain to form evidence storage data on the blockchain.

[0013] The present invention also proposes an employment monitoring system, the system comprising: the wearable terminal device, a backend server, and a computer program stored on the memory and executable on the processor, the computer program being configured to implement the steps of the employment monitoring method as described in any one of claims 1 to 8.

[0014] The employment monitoring method described in this application enables employment monitoring by acquiring data from wearable terminal devices such as smart bracelets worn by construction workers. The smart bracelets have built-in positioning modules such as GPS, BeiDou, and UWB, which can collect location data in real time. They also store the workers' identification information, including name, employee number, work permit number, and employer, and have built-in accelerometers to detect posture changes and activity levels. The wearable terminal devices transmit the collected data to a backend server in real time via wireless communication networks such as 4G, 5G, LoRa, and WiFi.

[0015] Obtain the corresponding work qualification list for each work process area. Different work process areas correspond to specific work types, such as high-altitude work areas and electrical work areas, and have different qualification requirements for construction personnel. Therefore, configure a corresponding work qualification list for each work process area. The work qualification list includes information such as the type, level, and validity period of the work operation certificate for personnel allowed to enter. For example, high-altitude work areas require high-altitude work operation certificates, and electrical work areas require electrician certificates.

[0016] Based on the location data, the location of the construction worker in the work area is determined. After receiving the location data, the backend server can use electronic fence technology to determine whether the construction worker has entered a certain work area.

[0017] If the location data determines that the construction worker is located in the specified work process area, a list of work qualifications corresponding to that work process area is obtained, and the construction worker's identity information is verified against the work qualification list. The identity information includes the construction worker's work operation certificate number and affiliated unit data. The verification process verifies whether the work operation certificate type corresponding to the work operation certificate number is within the qualification requirements, whether the work operation certificate is valid, and whether the affiliated unit possesses the corresponding construction qualifications.

[0018] If verification is successful, it indicates that the construction personnel are qualified to enter. They can be notified via wearable terminal devices (such as vibration or voice prompts) or on-site display devices that they are permitted to enter. The actual working hours of the construction personnel in the work area are recorded, and the working hour data is stored in a database for subsequent workload statistics and wage settlement. This method automates the recording of dwell time, reduces manual operation, and improves data real-time performance and accuracy. If verification fails, an alarm is triggered.

[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0023] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or" or "and / or" throughout the text includes three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied.

When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0025] In the process of subcontracting construction labor, construction sites typically contain multiple risk areas and different work processes, each with varying qualification requirements for workers. Traditional management methods rely on manual verification of qualifications and manual recording of working hours, which is prone to problems such as missed inspections, misjudgments, and information delays, affecting both safety management and operational efficiency. Furthermore, existing positioning systems often only provide location information and lack real-time linkage with qualification data, making it impossible to respond promptly when personnel enter risk areas.

[0026] Reference Figure 1 This invention proposes a method for monitoring labor use at construction sites, comprising the following steps: S10, acquire data from the wearable terminal device of the construction worker, including the construction worker's identity information and location data; S20, Obtain the work qualification list corresponding to the process area; S30, when the location of the construction personnel is determined to be in the work process area based on the location data, the identity information of the construction personnel is verified against the work qualification list corresponding to the work process area; S40: If the identity information of the construction personnel is successfully verified against the work qualification list corresponding to the work process area, the construction personnel are prompted to enter the work process area, and the actual working hours of the construction personnel in the work process area are recorded; if the verification of the identity information of the construction personnel fails to match the work qualification list corresponding to the work process area, an alarm is triggered.

[0027] The employment monitoring method described in this application enables employment monitoring by acquiring data from wearable terminal devices such as smart bracelets worn by construction workers. The smart bracelets have built-in positioning modules such as GPS, BeiDou, and UWB, which can collect location data in real time. They also store the workers' identification information, including name, employee number, work permit number, and employer, and have built-in accelerometers to detect posture changes and activity levels. The wearable terminal devices transmit the collected data to a backend server in real time via wireless communication networks such as 4G, 5G, LoRa, and WiFi.

[0028] Obtain the corresponding work qualification list for each work process area. Different work process areas correspond to specific work types, such as high-altitude work areas and electrical work areas, and have different qualification requirements for construction personnel. Therefore, configure a corresponding work qualification list for each work process area. The work qualification list includes information such as the type, level, and validity period of the work operation certificate for personnel allowed to enter. For example, high-altitude work areas require high-altitude work operation certificates, and electrical work areas require electrician certificates.

[0029] Based on the location data, the construction worker's location in the work area is determined. After receiving the location data, the backend server can use electronic fence technology to determine whether the construction worker has entered a certain work area.

[0030] If the location data pinpoints the work area where the construction personnel are located, obtain the corresponding work qualification list for that work area and verify the construction personnel's identity information against the work qualification list. The identity information includes the construction personnel's work operation certificate number and their affiliated unit data. The verification process must confirm whether the work operation certificate type corresponding to the work operation certificate number is within the qualification requirements, whether the work operation certificate is valid, and whether the affiliated unit possesses the corresponding construction qualifications.

[0031] If verification is successful, it indicates that the construction personnel are qualified to enter. They can be notified via wearable terminal devices (such as vibration or voice prompts) or on-site display devices that they are permitted to enter. Simultaneously, the actual working hours of the construction personnel in the work area will be recorded. This data will be stored in a database for subsequent workload statistics and wage settlement. This method automates the recording of actual working hours, reduces manual operation, and improves data real-time performance and accuracy. If verification fails, an alarm will be triggered.

[0032] In an embodiment of the present invention, before the step of obtaining the work qualification list corresponding to the work process area, the labor monitoring method further includes: dividing the construction task into multiple work processes, physically delineating the construction site according to the multiple work processes to obtain multiple work process areas, and configuring corresponding work qualification lists for the multiple work process areas.

[0033] A construction task can be broken down into multiple processes based on factors such as construction technology, job type, and safety level. For example, a building construction project can be divided into foundation engineering, main structural engineering, decoration and finishing engineering, and electromechanical installation engineering.

[0034] The construction site is physically divided into multiple process areas based on various work processes. This involves defining multiple pre-defined areas within the site, each corresponding to at least one work process. By utilizing task decomposition and area division, it is ensured that personnel with different qualifications can only enter the work process areas whose qualifications are verified, thereby effectively reducing safety risks.

[0035] Configure corresponding work qualification lists for multiple work process areas. This involves determining the permitted types of work qualifications for each work process area and linking this list to the area's geographical location information. For example, the qualification list for a high-altitude work area could include high-altitude work operation certificates and safety training qualification certificates; the qualification list for an electrical work area could include special operation certificates and high and low voltage electrician certificates. By binding the qualification lists to the work process areas, qualification verification can be automatically completed when personnel enter the corresponding work process area, greatly reducing the cost of manual inspection.

[0036] In an embodiment of the present invention, the steps of physically delineating the construction site into multiple process areas based on multiple processes and configuring corresponding work qualification lists for the multiple process areas include: establishing a BIM model based on a preset construction plan, dividing the spatial range of each process area in the BIM model according to the process, constructing an electronic fence based on the spatial range of each process area, and configuring corresponding work qualification lists for the electronic fence.

[0037] A BIM model is created based on a pre-set construction plan. BIM (Building Information Modeling) is a data tool used in engineering design, construction, and management. It can build a model containing information such as building structure, construction area, equipment and facilities based on architectural design drawings and construction plans.

[0038] Based on the construction process, the spatial scope of each process area is divided in the BIM model. This is achieved by drawing polygons and setting boundary coordinates to clearly define the spatial boundaries of each process area. Furthermore, multiple risk areas can be designated in the BIM model; these are areas prone to construction accidents. When a process area overlaps with a risk area, safety measures can be deployed in advance, and qualification restrictions can be set.

[0039] Electronic fences are constructed based on the spatial boundaries of each work process area. These electronic fences are virtual boundaries based on positioning technology, and can automatically detect and trigger corresponding actions when construction personnel enter or leave. The electronic fences are then linked to the corresponding work qualification lists to establish a mapping relationship between work process areas and these lists.

[0040] By embedding geofence data into the BIM model, process areas and geofences can be managed uniformly within the same three-dimensional coordinate system, achieving integrated modeling of process division and geofencing, facilitating subsequent dynamic updates. When a construction worker's smart bracelet detects that they have entered a geofenced area, the system can automatically retrieve the process information for that area and verify it against the associated qualification list. This real-time binding of spatial location data with process qualification data reduces manual judgment and improves verification speed and accuracy.

[0041] In an embodiment of the present invention, the identity information of the construction personnel includes the work operation certificate number and the data of the unit to which the construction personnel belong.

[0042] The work operation certificate number is a key piece of information proving that a construction worker possesses specific work qualifications. It includes details such as certificate type, specific number, issuing authority, and validity period. By verifying the work operation certificate number, it is possible to accurately determine whether a construction worker is qualified to enter a specific work area.

[0043] The affiliated unit data records relevant information such as the construction unit and labor service company to which the construction workers belong. Through the affiliated unit data, the responsible entity of the construction unit can be clearly identified, and in the event of a safety accident, responsibility can be traced quickly and effectively.

[0044] In embodiments of the present invention, the labor monitoring method further includes: calculating the actual workload of construction workers in the work area based on their actual working hours in the work area. Furthermore, an accelerometer can be used to detect whether workers are continuously moving to determine if they are in a working state, thereby improving the accuracy of the actual working hours calculation. In an embodiment of the present invention, the alarm triggering step includes at least one of the following: on-site audible and visual alarm, construction site broadcast prompt, and push alarm information to the wearable terminal device of construction personnel.

[0045] When the verification of the construction worker's identity information and the corresponding work qualification list for the work process area fails, the following alarm methods can be used: (1) On-site sound and light alarm, that is, an sound and light alarm is set up on site. Once triggered, it will emit sound and light warning at the same time to remind the construction personnel to leave immediately.

[0046] (2) Site broadcast reminders: use the site broadcast to broadcast warning information and remind construction workers to leave the site quickly.

[0047] (3) Push alarm information to the wearable terminal device of the construction personnel and push the alarm information to the smart bracelet of the construction personnel to remind the construction personnel to leave the site quickly.

[0048] In embodiments of the present invention, the employment monitoring method further includes generating at least one of the following reports according to a preset cycle: an attendance report, a workload statistics report, an abnormal behavior report, and a qualification verification result report, based on the employment data collected in real time.

[0049] Attendance reports are used to record the time when construction workers enter and leave the construction site, as well as the actual working hours in each work process area.

[0050] Workload statistics reports are used to record the actual working hours of construction workers in different work processes and areas.

[0051] Abnormal behavior reports are used to record specific information about each abnormal behavior, such as the time and place of occurrence, the personnel involved, the cause of the abnormal behavior, and the handling results. Abnormal behavior includes the behavior of construction personnel not being in the work area during working hours.

[0052] The qualification verification result report is used to record the qualification verification status of construction personnel in each process area.

[0053] In an embodiment of the present invention, the employment monitoring method further includes: performing hash operations on the attendance data of the attendance report, the actual working hours statistics of the workload statistics report, the abnormal behavior data of the abnormal behavior report, and the qualification verification results of the qualification verification result report to obtain hash values; packaging the attendance data, working hours statistics, abnormal behavior data, qualification verification results, and hash values ​​into blocks according to timestamps and writing them into the blockchain; and recording digital signatures and writing times on the blockchain to form evidence data on the blockchain.

[0054] As a distributed ledger technology, blockchain has significant characteristics such as decentralization, immutability, and traceability, which can effectively protect the authenticity and integrity of data and prevent data from being maliciously tampered with.

[0055] In the subcontracting settlement process, the evidence data stored on the blockchain can be automatically compared to verify the authenticity of attendance data, working hour statistics, abnormal behavior data, and qualification verification results. In the safety audit process, the authorized auditor can directly access the evidence data stored on the blockchain to quickly reconstruct key events in the construction process.

[0056] This invention also proposes a labor monitoring system, comprising: a wearable terminal device, a backend server, and a computer program stored in a memory and executable on a processor. The computer program is configured to implement the steps of the labor monitoring method described above. Because the labor monitoring system employs all the technical solutions of all embodiments of the labor monitoring method described above, it can achieve real-time verification of construction worker qualifications, automated work hour statistics, timely alarms for abnormal behavior, and blockchain-based evidence storage of labor data.

[0057] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
