Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and more specifically, to a tunnel work efficiency management system. Background Art

[0002] During tunnel construction, tunnel production dispatchers need to manually record the construction time, progress and problems encountered during the construction process of each part during the inspection of each construction area in the tunnel. However, manual records are prone to typos and unclear handwriting, which leads to inaccurate recorded information and difficulty in query. At the same time, environmental factors such as light and dust in the tunnel may also affect record archiving. The recorded data must be regularly entered into electronic spreadsheets for archiving. This process is cumbersome and error-prone. In addition, paper records are easily lost and damaged, which brings inconvenience to data management.

[0003] During regular construction meetings, managers will make detailed statistics on the time taken for each process this week, and through simple statistical analysis, they will look for problems with process connection or delays. However, manual recording makes it difficult to achieve real-time updates of construction data, which leads to processing delays for construction issues that require a quick response. When the amount of data is large, it is difficult to conduct effective data mining and analysis, which limits the optimization of construction management and the scientific nature of decision-making.

[0004] When performing progress analysis, the Engineering Management Department summarizes the progress analysis report based on the experience of the on-site dispatchers and makes overall scheduling arrangements. However, different inspectors may have different recording habits and standards, resulting in differences in the format and content of the recorded data, making it difficult to manage and analyze them in a unified manner.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0014] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from the description. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0015] A tunnel work efficiency management system, comprising a data acquisition system, a data transmission system, a data system, a tunnel information management system and a personnel management system; The data collection system includes ultra-wideband UWB positioning base station, access control gate and positioning card; The data transmission system is used to build a heterogeneous network, including active roaming access technology; the network is set up to ensure the continuity and stability of communication inside the tunnel.

[0016] The data system includes management database, data model library, business database and GIS spatial database. Various data at the front end of tunnel construction are classified and stored in various databases and provided to platform applications for comprehensive use; The information management system includes a tunnel basic information module and a tunnel surrounding rock grade recording module. The tunnel basic information module demarcates the attendance area of ​​the construction area and communicates with the personnel gate in the construction area. It is suitable for basic information maintenance scenarios of different sections of the tunnel, and can simultaneously demarcate the attendance area. After the personnel gate is installed, both attendance information and synchronous entry and exit personnel records can be obtained. The construction progress of the excavation, invert, and secondary lining sub-projects can be manually updated and maintained. The tunnel surrounding rock grade recording module updates the surrounding rock distribution of the tunnel in real time; when the surrounding rock grade changes, an early warning can be issued to inform the corresponding staff to adjust the corresponding plans and measures for the changed surrounding rock grade in a timely manner.

[0017] The personnel management system adopts a real-name system with one card for each person. When all relevant personnel are entered, they will be bound to the positioning card. When the corresponding personnel carry the positioning card, all areas and locations of the corresponding personnel can be identified; It also includes a construction record module, an early warning management module, a tunnel dispatch command center module, and a tunnel data analysis module; The construction record module graphically displays the ongoing cycle construction process; displays the completed construction process and cycle record information in a table; when the automatic process fails to start due to a power outage system fault light problem, the execution status of the process can be manually reported; The early warning management module includes disconnection timeout alarm, surrounding rock grade change alarm, emergency rescue, process standard working time overtime alarm, cycle timeout alarm and low power alarm; The tunnel dispatching and command center module aggregates and analyzes various data, displays the overall construction progress of the tunnel, daily, weekly and monthly construction footage, visually tracks the personnel distribution and construction status in the tunnel, and provides intuitive chart display of process records, personnel information statistics and early warning record viewing; The tunnel data analysis module is used to predict and analyze the progress of the tunnel in the next 30 days: actual completion rate: actual completion / total length*100%, progress in the next month: (the number of excavations in the next month + the actual number of completions) / total length*100%, the number of monthly cycles X=30 days*(24 hours / each cycle time Y), the monthly footage C=the number of monthly cycles X*L1, L1: take the mode of the footage of this month under the current surrounding rock grade. Example: Each cycle takes 20 hours L1: 3 meters The number of monthly cycles = 30*(24 / 20) = 36 Monthly advance = 36*3 = 108 meters, which is equivalent to 108 meters of excavation in 36 cycles in the next month. However, the above excavation calculation is equivalent to the calculation under the same surrounding rock grade on the working days of the next month. The cycle time and footage remain unchanged. The actual number of cycles per month X = 30 days * (24 hours / each cycle time Y), the monthly footage C = the number of cycles per month * L L1: Take the mode of footage of level 1 surrounding rock grade last month as the footage of that grade next month L2: Take the mode of footage of level 2 surrounding rock grade last month as the footage of that grade next month L3: Take the mode of footage of level 3 surrounding rock last month as the footage of that level next month L4: Take the mode of footage of the 4th grade surrounding rock last month as the footage of the next month of that grade L5: Take the mode of footage of the 5th grade surrounding rock last month as the forecast of footage of the grade next month Assume that the first section starts from the current construction pile number and the current surrounding rock grade is grade 1 The footage is L1=2. We know that the surrounding rock grade 1 is 50 meters = C1. The time for each cycle is Y=30 Number of cycles this month X = C1 / L1 = 25 Number of days for excavation of surrounding rock grade 1 D1 = number of cycles this month X / (24 hours / time per cycle Y) D1=30 / (24 / 30)=24 D1<30 days D2=30-D1=6 The second section is the secondary surrounding rock grade Y=15 L2=3 C=20 X=6(24 / 15)=9.6 C2=X*L2=28.8 meters Is C2 less than the length of the surrounding rock grade 2 (c)? If less than then This month's footage C = C1 + C2 = 50 + 28.8 = 78.8 meters C2 is greater than the length of the surrounding rock grade 2. The required length of surrounding rock grade C2-2 is c2=28.8-20=8.8 D2 is calculated and then calculated according to the judgment of d1+d2 below In summary: The first section: Given footage L1 Time per cycle Y1 C1 It can be calculated that X=C1 / L1 D1=X / (24 / Y1) D1 and 26 days comparison D1=30, then excavation this month is C1 meters. D1<30, the second section is D2 C2. If D1+D2=30, then C=C1+C2 D1+D2>30 Then c2=((30-D1)24H / Y2) c=c1+c2 D1+D2<30 Continue to calculate the time Dn used for the next construction period until D1+D2+Dn>30, then Cn=(30-D1-D2-Dn)*24H / Yn)*Ln) C=C1+C2+....Cn D1>26 C=30*(24H / Y)*L Through real-time data communication between the sensing equipment on the construction site and the software platform, the real-time location information of personnel and machinery, the working condition information of the construction area, and the personnel access information are transmitted to the data processing server in real time. The combination of personnel and machinery in the construction area is converted into a process, and the time when personnel and machinery enter and exit the construction area is used to determine the start and end of the tunnel construction process.
