Description

Technical Field

[0001] The present invention relates to the technical field of engineering project data management, and in particular to a cloud platform-based infrastructure project scheduling system and method. Background Art

[0002] In order to effectively manage the construction data of infrastructure construction projects, the existing technology uniformly collects and manages infrastructure construction data by establishing an information system. However, the current construction project information management platform only performs simple storage and information sorting of construction project data, and cannot effectively apply the data generated during the construction process. Especially the construction progress data and safety monitoring data during the construction process. Safety monitoring of project construction can provide guarantees for the smooth progress of construction projects, but the construction department and the safety monitoring department belong to two different work departments. There is a lack of coordinated management of data between the two work departments, which makes it impossible to effectively feedback the safety monitoring data to the construction department, and the construction site cannot eliminate safety hazards in time. Summary of the invention

[0003] The purpose of the present invention is to provide a cloud platform-based infrastructure project scheduling system and method to solve the problems raised in the prior art.

[0004] To achieve the above object, the present invention provides the following technical solution: a cloud platform-based infrastructure project scheduling method, the method comprising: Step S100: Obtain construction history records of several infrastructure projects, wherein any infrastructure project includes several construction stages, classify the same construction stages into the same category, classify and manage the construction records according to the category of the construction stage, obtain the safety monitoring records in each construction stage, and collect the construction history records without safety accidents to obtain a safe construction record set; Step 200: Obtain the safety monitoring records of relevant safety managers in the infrastructure project, digitize the safety monitoring tasks performed by the safety managers, collect the safety monitoring tasks performed by the relevant managers during the construction phase, and obtain a monitoring reference sequence; Step S300: Obtain the historical records of safety accidents in the infrastructure project. In the historical records, set the construction stage corresponding to a safety accident as the target construction stage, obtain the construction plan and safety monitoring plan of the target construction stage, and calculate the difference between the actual construction safety monitoring investment and the safety monitoring plan of the target construction stage; Step S400: evaluating the difference between the actual construction progress and the construction plan during the actual construction process through the difference degree, and evaluating the risk of the construction stage where the safety accident occurs; Step S500: Building an information platform, collecting construction progress data and safety monitoring data during the construction process, collecting risk assessment records of the same type of construction progress at the stage of safety accidents, performing data analysis on the risk assessment records, and obtaining risk assessment thresholds for the construction stage; Step S600: Monitor the construction progress and safety monitoring progress of the current infrastructure project separately, calculate the difference between the actual construction safety monitoring investment and the safety monitoring plan and the difference between the actual construction progress and the construction plan in the current infrastructure project, and issue an information reminder when the calculated result is greater than the risk assessment threshold of the corresponding construction stage.

[0005] Furthermore, step S100 includes: Step S101: Obtain all construction records of any infrastructure project, obtain construction history records corresponding to all construction stages of any infrastructure project, arrange the construction records according to the sequence of the construction stages, and obtain a construction record sequence of any infrastructure project; Step S102: collecting safety monitoring records during the implementation of the infrastructure project, wherein one safety monitoring record corresponds to a safety monitoring task performed once by a relevant safety monitoring personnel of the infrastructure project; Step S103: For any construction record sequence, when there is no safety accident in the construction history record corresponding to the construction stage, the construction history record corresponding to the construction stage is marked as a safe construction record, and all safe construction records corresponding to the same type of construction stage are collected to obtain a set of safe construction records corresponding to each type of construction stage; The historical records of the same type of construction phases are managed separately, and the differences between the records of safety accidents and those without safety accidents are extracted to provide an evaluation basis for the project management platform.

[0006] Further, step S200 includes: Step S201: Collect all safety monitoring records during the implementation of all infrastructure projects, label the safety monitoring tasks according to their types, and obtain the task sequence number of each safety monitoring task; Step S202: From the time range corresponding to any safety construction record, obtain the safety monitoring tasks of the relevant safety monitoring personnel for the construction phase of the infrastructure project, arrange the safety monitoring tasks according to the time sequence, convert the safety monitoring tasks into corresponding task numbers, and obtain the digital sequence corresponding to any safety construction record; 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; The safety monitoring tasks are marked with digital serial numbers. The same digital serial number is used to mark 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.

[0007] Furthermore, step S300 includes: Step S301: Obtain the total amount of the project 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, wherein the safety monitoring task plan is a set of safety monitoring tasks; Step S302: Collect the target period and all unit detection times before the target period to obtain the safety monitoring period, obtain the project completion amount wc and the planned completion amount of the safety monitoring task rc in the safety monitoring period, the planned completion amount of the safety monitoring task is the set of safety monitoring tasks completed in the safety monitoring period, calculate the project completion progress α and the monitoring progress β, where, α=wc / W0, β=rc / R0, calculate the first difference coefficient A, A=|α-β|; The construction phase is divided into several unit management intervals. α represents the proportion of construction workload in the unit interval where safety accidents occur, and β represents the proportion of monitoring tasks completed in the unit interval where safety accidents occur. By comparing α and β, the gap between the investment in construction of infrastructure projects and the investment in safety monitoring in the unit interval where safety accidents occur is obtained. 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.

[0008] Step S303: Calculate the proportion τ of the safety monitoring cycle, τ=Tc / T0, where Tc represents the time length of the safety monitoring cycle, obtain the monitoring reference sequence corresponding to the same type of construction stage as the target construction stage, and borrow the first τ% sequence from the monitoring reference sequence as the first target sequence; Step S304: convert the safety monitoring tasks in rc into corresponding task numbers to obtain a risk task sequence, calculate the difference between the risk task sequence and the first target sequence, and record the difference as the second difference coefficient B; The second difference coefficient B measures the difference between the safety monitoring tasks actually performed and the safety monitoring tasks that need to be performed during the construction phase in a safe state.

[0009] Furthermore, step S400 includes: Step S401: Obtain a unit monitoring cycle with a time length of t0, divide the target construction phase into several unit monitoring cycles, record the unit monitoring cycle where the safety accident occurs as the target cycle, obtain the construction workload W1 in the target cycle, and calculate the construction rate difference value vd. vd=|(W1 / t0)-(W0 / T0)|; vd indicates the difference between the actual construction progress and the planned progress during the unit monitoring cycle. When the difference between the actual construction progress and the planned progress is too large, it is more likely to cause safety hazards; Step S402: Calculate the risk assessment coefficient u of the target construction stage. u = (A + B) × e q×vd , where e is a natural constant and q is a weight coefficient; In order to avoid insufficient weight in the risk assessment coefficient due to small vd values, the vd data is amplified by an exponential function, and q is used as a weighting coefficient to control the amplification factor of the exponential function. Once the q value is determined, it will be used in subsequent calculation processes.

[0010] Furthermore, step S500 includes: Step S501: Setting a first data storage location and a second storage location in the information platform, 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; Step S502: Obtain all target construction stages of any type of construction stage, obtain the risk assessment coefficient corresponding to each target construction stage in all target construction stages, and obtain the minimum value of the risk assessment coefficient as the risk assessment threshold of any type of construction stage.

[0011] Furthermore, step S600 includes: Step S601: Set the currently monitored infrastructure project as the current project, set the construction phase being implemented in the current project as the current construction phase, and obtain the construction plan for the current construction phase, which includes: the total amount of the project W11 for the current construction phase, the total planned completion time T11 for the current phase, and the safety monitoring task plan R11 for the current construction phase; Step S602: Divide the current construction phase into several unit monitoring cycles, obtain the calculated construction rate difference value vid, obtain the engineering completion quantity wic and the safety monitoring task plan completion quantity ric in the i-th unit monitoring cycle, and use the method in step S400 to calculate the risk assessment coefficient ui of the current construction phase; Step S603: Obtain a risk assessment threshold Q corresponding to the same type of construction stage as the current construction stage, and when ui≥Q, issue an alarm to the management personnel of the current project.

[0012] In order to better implement the above method, a cloud platform-based infrastructure project scheduling system is also proposed, which includes: The system includes: a construction record management module, a monitoring record management module, a historical data evaluation module, a construction monitoring module and a risk assessment module, wherein the construction record management module is used to manage the historical data of the construction of the infrastructure project, the monitoring record management module is used to manage the historical data of the safety monitoring of the infrastructure project process summary, the historical data evaluation module is used to evaluate the risk of the construction stage where the safety accident occurred in the historical data, the construction monitoring module is used to manage the construction records and safety monitoring records in the current infrastructure construction project, and the risk assessment module is used to evaluate the risk of the construction stage in the current infrastructure construction project; The construction record management module includes: a construction record classification unit, a risk record management unit and a safety record management unit, wherein the construction record classification unit is used to obtain the construction records of the infrastructure project, and divide the construction records into historical records with safety accidents and historical records without safety accidents, the risk record management unit is used to manage historical records of safety accidents, and the safety record management unit is used to manage historical records without safety accidents; The monitoring record management module includes: a monitoring record management unit, a monitoring task management unit and a digital management unit, wherein the monitoring record management unit is used to manage the historical records of safety monitoring in infrastructure projects, the monitoring task management unit is used to sort the safety monitoring tasks corresponding to the safety monitoring tasks, and the digital management unit is used to convert the safety monitoring task sequence into a digital sequence; The historical data evaluation module includes: a construction record comparison unit, a first difference coefficient calculation unit, a second difference coefficient calculation unit, a construction rate difference calculation unit and a risk assessment coefficient calculation unit, wherein the construction record comparison unit is used to compare the planned progress and the actual completion progress of the infrastructure project, the first difference coefficient calculation unit is used to calculate the difference between the engineering completion progress and the monitoring completion progress of the infrastructure project within a unit time range, the second difference coefficient calculation unit is used to compare the difference between the actually performed safety monitoring task and the monitoring reference sequence, the construction rate difference calculation unit is used to calculate the difference between the actual construction rate and the planned construction rate, and the risk assessment coefficient calculation unit is used to calculate the risk assessment coefficient; The construction monitoring module includes: a storage location management unit and a risk threshold management unit, wherein the storage location management unit is used to store construction records and safety monitoring records respectively, and the risk threshold management unit is used to manage the risk assessment threshold corresponding to the construction stage; The risk assessment module includes: a construction project management unit, a risk assessment unit and a risk judgment unit, wherein the construction project management unit is used to collect data on the current infrastructure construction project, the risk assessment unit is used to calculate the risk assessment value of the current construction stage, and the risk judgment unit is used to obtain the risk assessment threshold and issue an alarm when the threshold is exceeded.
