Description

Technical Field

[0001] This utility model relates to the field of engineering control equipment technology, and in particular to an early warning device for engineering project progress deviation. Background Technology

[0002] In engineering project management, it is crucial to promptly and accurately grasp project schedule deviations and issue early warnings.

[0003] Traditional progress monitoring methods often rely on regular manual inspections and experience-based judgments, which are characterized by lag and subjectivity, making it difficult to meet the needs of modern engineering projects for efficient and precise management. To address the shortcomings of these technologies, we propose an early warning device for engineering project progress deviations. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an early warning device for project schedule deviations.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An early warning device for project progress deviation includes a structural beam with symmetrically arranged legs on both sides of its bottom. A stabilizing pad is fixedly connected to the bottom of each leg. A central control component for project progress and a battery box are arranged on the right side wall of each leg. The central control component includes a back plate with a sealed protective box fixedly installed on its side. A control host is fixedly installed inside the sealed protective box, and the control host has an LCD screen and a keyboard input area. A data transmission interface is fixedly installed on the side of the LCD screen, extending through to the outside of the sealed protective box. A sealed door is rotatably installed on the side of the sealed protective box, and an electronic combination lock and a handle are fixedly installed on the door. A fingerprint sensor is fixedly installed on the electronic combination lock.

[0006] Furthermore, a lower folding seat is screwed onto the bottom of the structural beam, and a high-definition camera is screwed onto the lower folding seat.

[0007] Furthermore, a lamp holder is screwed to the bottom of the structural beam, the lamp holders are staggered between the lower folding seats, and an alarm light is fixedly installed on the lower side of the lamp holder.

[0008] Furthermore, several upper folding seats are fixedly installed at equal intervals on the upper side of the structural beam, and lamp covers are fixedly connected to the sides of the upper folding seats. Supplemental lighting tubes are fixedly installed inside the lamp covers.

[0009] Furthermore, an electronic display screen is screwed onto the front side of the structural beam.

[0010] Furthermore, a photosensitive sensor is fixedly installed on the upper side of the structural beam.

[0011] Furthermore, sleeves are symmetrically fixedly installed on the lower side of the structural beam, the upper end of the support leg is inserted into the inner side of the sleeve, and a limiting screw is screwed onto the side wall of the sleeve. The limiting screw is made of stainless steel and the inner end of the limiting screw abuts against the outer wall of the upper end of the support leg.

[0012] Furthermore, the battery box is electrically connected to a connecting cable on its side, and a power plug is fixedly connected to the end of the connecting cable. Both the battery box and the back plate are screwed onto the side wall of the support legs.

[0013] Compared with related technologies, the project schedule deviation early warning device proposed in this utility model has the following beneficial effects: This invention discloses a project progress deviation early warning device, which, through its integrated design, resembles an entrance / exit gate at a construction site. Currently, workers enter construction sites primarily using fingerprint attendance, which can lead to missed attendance. The central control unit for project progress automatically identifies workers by comparing facial features captured by a high-definition camera with pre-entered worker data. When a worker enters the construction site, the system automatically clocks in and records the time. Furthermore, the control unit inside the sealed protective box requires authorized personnel to open the box, preventing accidental access by unauthorized personnel. The control unit allows management personnel to input daily project progress data and simultaneously imports the daily number of workers into a pre-set program for analysis. This program calculates and displays the deviation between the completed work and the planned value, showing the result on an electronic display screen. When the deviation exceeds a preset progress deviation range, the control unit activates an alarm light, indicating the need to accelerate the project. The entire project progress warning and analysis utilizes a pre-set program within the control unit, avoiding the lag and subjectivity inherent in manual judgment and analysis, thus facilitating accurate monitoring of project progress deviations.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Reference Figures 1-5 An early warning device for project progress deviation includes a structural beam 1, with symmetrical support legs 4 on both sides of the bottom of the structural beam 1. A stabilizing pad 5 is fixedly connected to the bottom of the support legs 4. A project progress central control component 6 and a battery box 7 are installed on the side wall of the right support leg 4. The project progress central control component 6 includes a back plate 61, a sealed protective box 62 is fixedly installed on the side of the back plate 61, a control host 67 is fixedly installed inside the sealed protective box 62, an LCD screen 68 and a keyboard input area 69 are provided on the control host 67, a data transmission interface 610 is fixedly installed on the side of the LCD screen 68, the data transmission interface 610 passes through to the outside of the sealed protective box 62, a sealed box door 63 is rotatably installed on the side of the sealed protective box 62, an electronic combination lock 64 and a handle 66 are fixedly installed on the sealed box door 63, and a fingerprint press plate 65 is fixedly installed on the electronic combination lock 64.

[0018] With the above-described settings, the electronic combination lock 64 can be unlocked by entering a numeric password, or by pressing a finger on the fingerprint sensor 65. This provides two unlocking methods for the convenience of administrators. The electronic combination lock 64 uses common existing technologies, which will not be elaborated on here.

[0019] With the data transmission interface 610 configured, relevant administrators can periodically export data from the control host 67 via the data transmission interface 610 for backup and further analysis. In this method, sleeves 2 are symmetrically fixedly installed on the lower side of the structural beam 1, and the upper end of the support leg 4 is inserted into the inner side of the sleeve 2. A limiting screw rod 3 is screwed onto the side wall of the sleeve 2. The limiting screw rod 3 is made of stainless steel and the inner end of the limiting screw rod 3 abuts against the outer wall of the upper end of the support leg 4.

[0020] With the above-described configuration, the support leg 4 can be removed from the sleeve 2, facilitating the disassembly and transportation of the entire device.

[0021] In this configuration, a connecting cable 8 is electrically connected to the side of the battery box 7, and a power plug 9 is fixedly connected to the end of the connecting cable 8. The battery box 7 and the back plate 61 are both screwed onto the side wall of the support leg 4.

[0022] With the above-described configuration, both the battery box 7 and the back plate 61 are screwed onto the side wall of the support leg 4, allowing the relevant components on the side wall of the support leg 4 to be disassembled, facilitating disassembly, transportation, and on-site assembly.

[0023] In this method, a lower folding seat 13 is screwed to the bottom of the structural beam 1, and a high-definition camera 14 is screwed to the lower folding seat 13.

[0024] With the above-described setup, the high-definition camera 14 is tilted downwards. When a worker goes to work and passes under the structural beam 1, the worker's facial features can be captured and photographed by the high-definition camera 14, and the captured image is transmitted to the control host 67 for data comparison.

[0025] In this configuration, a lamp holder 11 is screwed to the bottom of the structural beam 1, and the lamp holders 11 are staggered between the lower folding seats 13. An alarm light 12 is fixedly installed on the lower side of the lamp holder 11, and an electronic display screen 10 is screwed to the front side of the structural beam 1.

[0026] With the above settings, the electronic display screen 10 is used to display data such as project completion progress, construction period, and deviation from the plan.

[0027] In this method, several upper folding seats 15 are fixedly installed at equal intervals on the upper side of the structural beam 1, lamp covers 16 are fixedly connected to the side of the upper folding seats 15, supplementary light tubes 17 are fixedly installed inside the lamp covers 16, and photosensors 18 are fixedly installed on the upper side of the structural beam 1.

[0028] With the above-described setup, when the photosensitive sensor 18 senses dim light, it transmits the light data to the control host 67. The control host 67 then controls the supplementary lighting tube 17 to turn on, providing supplementary lighting to the area below the structural beam 1, facilitating the high-definition camera 14 to capture images, and also providing illumination for workers entering the area.

[0029] The working principle of the project schedule deviation early warning device provided by this utility model is as follows: When workers enter the construction site, they must pass under the structural beam 1. At this time, a high-definition camera 14, tilted downwards, captures the worker's facial features and takes a picture. The captured image data is transmitted in real time to the control host 67 within the central control component 6 for project progress. The control host 67 compares the received facial feature data with pre-entered worker data. If the comparison is successful, the check-in operation is automatically completed, and the time when the worker entered the construction site is accurately recorded. This facial recognition-based check-in method effectively avoids missed check-ins that exist with traditional fingerprint check-in, providing accurate personnel attendance data for subsequent project progress management. Relevant management personnel need to open the sealed door 63 of the sealed protective box 62 by entering a digital password through the electronic password lock 64 or pressing their fingerprint on the fingerprint press plate 65. After entering the sealed protective box 62, the actual progress data of the project is entered daily using the keyboard input area 69 on the control host 67. Simultaneously, data such as the number of personnel involved in the work that day are imported into the background preset program of the control host 67, providing comprehensive data support for subsequent project progress analysis. The preset program inside the control host 67 will conduct in-depth analysis based on the actual project completion progress data and personnel number information entered daily, combined with the pre-set project plan progress data. Through complex algorithms, the deviation between the actual project completion and the planned value is calculated, and the deviation value, along with relevant data such as project completion progress and construction period, is clearly displayed on the electronic display screen 10. Once the calculated progress deviation exceeds the preset deviation range, the control host 67 will immediately issue a command to control the alarm light 12 installed at the bottom of the structural beam 1 to start flashing, conspicuously alerting relevant personnel on site that the current project progress is lagging behind and needs to be accelerated, thereby achieving timely early warning of project progress deviation.

[0030] In the specific implementation of this application, the key technical content of the internal program of the control host 67 is described as follows: A project progress analysis system based on big data analysis and artificial intelligence algorithms is pre-embedded inside the control host 67. The core algorithm of this system adopts a combination of time series analysis and regression models in machine learning. At the beginning of the project, the managers enter detailed project schedule data into the system, including the start time, end time, and expected workload of each stage of the task.

[0031] Simultaneously, data on various influencing factors related to project progress, such as work efficiency data of workers in different trades, supply cycle data of common construction materials, and progress impact data of similar projects under different weather conditions, are imported into the system as historical data samples. Each day, managers input actual project progress data into the control host 67 via the keyboard input area 69. This includes, for example, the specific amount of work completed and the manpower and hours invested. The system acquires real-time worker attendance data captured and transmitted by the high-definition camera 14, calculating the actual number of workers involved in construction that day and their working hours. Furthermore, the system can interact with other intelligent devices on the construction site (such as material management systems and equipment status monitoring systems) through the data transmission interface 610 to obtain data on the actual usage of construction materials, equipment runtime, and malfunctions. The system compares and analyzes these real-time collected actual data with pre-entered planned data. Earned Value Management (EVM) is used to calculate project progress deviations.

[0032] Specifically, based on the actual amount of work completed and the pre-set unit work budget cost, the budgeted cost for work performed (BCWP) is calculated. Simultaneously, based on the planned schedule, the budgeted cost for the amount of work that should be completed at the current time is calculated, i.e., the budgeted cost for work scheduled (BCWS). The schedule variance (SV) is calculated as SV = BCWP - BCWS. A negative SV indicates that the actual progress is behind the planned progress; a positive SV indicates that the actual progress is ahead of the planned progress. In addition to simple schedule variance calculation, the system also uses time series analysis algorithms to perform trend analysis on historical and real-time progress data to predict the trend of project progress in the near future. For example, by analyzing the daily schedule variance data over the past week or month, it can determine whether the schedule variance shows a gradually increasing or decreasing trend. If the trend indicates that the schedule deviation is increasing and is about to exceed the preset schedule deviation range, the system will issue an early warning signal even if the current schedule deviation value has not yet reached the warning threshold, reminding managers to take measures in advance, such as increasing manpower and optimizing construction processes, to avoid further delays. When the calculated schedule deviation exceeds the deviation range preset in the system, the control host 67 immediately activates the warning mechanism. The system sends an electrical signal to the alarm light 12 installed on the lamp holder 11 at the bottom of the structural beam 1 through its internal control circuit, causing the alarm light 12 to flash, conspicuously alerting relevant personnel on site that the current project progress is lagging and needs to be accelerated. At the same time, the system can also send the warning information to the mobile terminal devices (such as mobile phones, tablets, etc.) of managers through the data transmission interface 610, ensuring that managers can receive the warning information in a timely manner regardless of their location, so as to make quick decisions and take effective measures to adjust the project progress and ensure that the project proceeds smoothly as planned.
