Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of project data management, and particularly relates to a cloud platform-based infrastructure project scheduling system and method. BACKGROUND

[0002] In order to effectively manage the construction data of infrastructure construction projects, the prior art collects and manages the construction data of infrastructure projects through the establishment of an information system. However, the current construction project information management platform only stores and sorts the construction project data simply, and cannot effectively apply the data generated in the construction process. In particular, the construction progress data and safety monitoring data in the construction process. Safety monitoring of project construction can provide protection for the smooth progress of the construction project, but the construction department and the safety monitoring department belong to two different working departments, and the data between the two working departments lacks collaborative management, so that the safety monitoring data cannot be effectively fed back to the construction department, and the safety hazards in the construction site cannot be eliminated in time. SUMMARY

[0003] The present application aims to provide a cloud platform-based infrastructure project scheduling system and method to solve the problems in the prior art.

[0004] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a cloud platform-based infrastructure project scheduling method, the method comprising:

[0005] Step S100: obtaining the construction history records of a plurality of infrastructure projects, wherein any one infrastructure project comprises a plurality of construction stages, the same construction stages are divided into the same class, the construction records are classified and managed according to the categories of the construction stages, the safety monitoring records in each construction stage are obtained, and the construction history records without safety accidents are collected to obtain a safety construction record set;

[0006] Step 200: obtaining the safety monitoring records performed by the relevant safety management personnel in the infrastructure project, digitally processing the safety monitoring tasks performed by the safety management personnel, collecting the safety monitoring tasks performed by the relevant management personnel in the implementation process of the construction stage, and obtaining a monitoring reference sequence;

[0007] Step S300: obtaining the history records of safety accidents in the infrastructure project, setting the construction stage corresponding to a safety accident as a target construction stage in the history records, obtaining the construction plan and safety monitoring plan of the target construction stage, and calculating the difference degree between the actual construction safety monitoring input of the target construction stage and the safety monitoring plan;

[0008] Step S400: evaluating the difference between the actual construction progress and the construction plan in the actual construction process through the difference degree, and evaluating the risk of the construction stage where the safety accident occurs;

[0009] Step S500: build an information platform, collect construction progress data and safety monitoring data in the construction process, collect risk assessment records of the same type of construction progress in the safety accident stage, analyze the risk assessment records, and obtain the risk assessment threshold of the construction stage;

[0010] Step S600: respectively monitor the construction progress and safety monitoring progress in the current infrastructure project, calculate the difference between the actual construction safety monitoring input and the safety monitoring plan and the difference between the actual construction progress and the construction plan in the current infrastructure project, and when the calculation result is greater than the risk assessment threshold of the corresponding construction stage, information is reminded.

[0011] Further, step S100 includes:

[0012] Step S101: obtain all construction stages of any infrastructure project, obtain all construction history records corresponding to the construction stages in any infrastructure project, arrange the construction records according to the sequence of the construction stages, and obtain the construction record sequence of any infrastructure project;

[0013] Step S102: collect safety monitoring records in the implementation process of the infrastructure project, wherein one safety monitoring record corresponds to the execution of a safety monitoring task by a related safety monitoring personnel of the infrastructure project;

[0014] Step S103: for any construction record sequence, when there is no safety accident in the construction history record corresponding to the construction stage, mark the construction history record corresponding to the construction stage as a safe construction record, collect all safe construction records corresponding to the same type of construction stage, and obtain the safe construction record set corresponding to each type of construction stage;

[0015] The history records of the same type of construction stage are managed respectively, the differences between the records with and without safety accidents are extracted, and evaluation basis is provided for the project management platform.

[0016] Further, step S200 includes:

[0017] Step S201: collect all safety monitoring records in the implementation process of all infrastructure projects, label the safety monitoring tasks according to the types of the safety monitoring tasks, and obtain the task sequence number of each type of safety monitoring task;

[0018] Step S202: from the time range corresponding to any safety construction record, obtain the safety monitoring task of the related safety monitoring personnel to the construction stage of the infrastructure project, arrange the safety monitoring tasks according to the time sequence, convert the safety monitoring tasks into corresponding task sequence numbers, and obtain the digital sequence corresponding to any safety construction record;

[0019] Step S203: Obtain the digital sequence corresponding to all safety construction records of a certain construction stage, perform feature extraction on the digital sequence, and obtain the monitoring reference sequence corresponding to the certain construction stage;

[0020] The safety monitoring tasks are marked with digital serial numbers. The same digital serial number marks the same safety monitoring task. The safety monitoring tasks are converted into digital sequences, which makes it easy to compare the differences in the safety monitoring tasks in subsequent steps.

[0021] Furthermore, step S300 includes:

[0022] Step S301: Obtain the total project volume W0 of the target construction phase and the planned total completion time T0 of the target construction phase from the construction plan of the target construction phase, and obtain the safety monitoring task plan R0 of the target construction phase, where the safety monitoring task plan is a set of safety monitoring tasks;

[0023] Step S302: Collect the target period and all unit inspection times before the target period to obtain the safety monitoring period, obtain the project completion amount wc and the safety monitoring task planned completion amount rc in the safety monitoring period, the safety monitoring task planned completion amount is the set of all completed safety monitoring tasks in the safety monitoring period, calculate the project completion progress α and the monitoring progress β, where,

[0024] α=wc / W0,β=rc / R0,calculate the first difference coefficient A,A=|α-β|;

[0025] The construction phase is divided into several unit management intervals. α represents the proportion of construction workload in the unit interval where a safety accident occurred, and β represents the proportion of monitoring tasks completed in the unit interval where a safety accident occurred. By comparing α and β, the gap between the investment in construction of the capital construction project and the investment in safety monitoring in the unit interval where a safety accident occurred is obtained.

[0026] Generally speaking, the safety monitoring tasks of infrastructure projects are carried out in collaboration with construction projects. As the amount of construction tasks increases, the workload of safety monitoring tasks also increases. When the A value increases, it indicates that there may be problems in the coordination between construction projects and safety monitoring tasks.

[0027] Step S303: Calculate the proportion τ of the safety monitoring period, τ = Tc / T0, where Tc represents the duration of the safety monitoring period, obtain the monitoring reference sequence corresponding to the same type of construction phase as the target construction phase, and borrow the first τ% of the monitoring reference sequence as the first target sequence;

[0028] Step S304: converting the safety monitoring tasks in the rc into corresponding task sequence numbers to obtain a risk task sequence, and calculating the difference between the risk task sequence and the first target sequence, and the difference is denoted as a second difference coefficient B;

[0029] The second difference coefficient B measures the difference between the actual safety monitoring tasks and the safety monitoring tasks required in the safety state construction phase.

[0030] Further, step S400 includes:

[0031] Step S401: obtaining a unit monitoring period with a time length of t0, dividing the target construction phase into a plurality of unit monitoring periods, recording a unit monitoring period in which a safety accident occurs as a target period, obtaining a construction workload W1 in the target period, and calculating a construction rate difference value vd,

[0032] vd = | (W1 / t0) - (W0 / T0) |;

[0033] The vd indicates the difference between the actual construction progress and the planned progress in the unit monitoring period, and when the difference between the actual construction progress and the planned progress is too large, safety hazards are more likely to occur;

[0034] Step S402: calculating a risk assessment coefficient u of the target construction phase,

[0035] u = (A + B) × e q×vd where e is a natural constant and q is a weight coefficient;

[0036] In order to avoid the insufficient weight value of vd in the risk assessment coefficient due to the small value of vd, the vd data is amplified by an exponential function, and q is used as a weighting coefficient to control the amplification ratio of the exponential function. Once the value of q is determined, it is used in the subsequent calculation process.

[0037] Further, step S500 includes:

[0038] Step S501: setting a first data storage location and a second data storage location in the information platform, and uploading the implementation data of the infrastructure project to the information platform, wherein the construction progress data of the current infrastructure project is uploaded to the first data storage location, and the safety monitoring data of the current infrastructure project is uploaded to the second data storage location;

[0039] Step S502: obtaining all target construction phases of any type of construction phase, obtaining the risk assessment coefficients corresponding to each target construction phase in all target construction phases, and obtaining the minimum value in the risk assessment coefficients as the risk assessment threshold of any type of construction phase.

[0040] Further, step S600 includes:

[0041] Step S601: setting the current monitored infrastructure project as a current project, setting the construction phase being implemented in the current project as a current construction phase, obtaining a construction plan of the current construction phase, the construction plan including: an engineering total amount W11 of the current construction phase, a planned total completion time T11 of the current phase, and a safety monitoring task plan R11 of the current construction phase;

[0042] Step S602: dividing the current construction phase into a plurality of unit monitoring periods, obtaining a calculation construction rate difference value vid, obtaining an engineering completion amount wic and a safety monitoring task plan completion amount ric in the i-th unit monitoring period, and using the method in step S400 to calculate a risk assessment coefficient ui of the current construction phase.

[0043] Step S603: obtaining a risk assessment threshold Q corresponding to the same type of construction phase as the current construction phase, and when ui≥Q, an alarm prompt is given to the management personnel of the current project.

[0044] In order to better implement the above method, a cloud platform-based infrastructure project scheduling system is also proposed, the system comprising:
