Description

Technical Field

[0001] The present invention relates to the technical field of engineering monitoring, and in particular to a monitoring system for the construction quality of four-electricity engineering. Background Art

[0002] The Four-Electricity Project is the general term for communication, signal, electricity and electric traction power supply projects in high-speed railway construction. It is the "central brain" and source of power for the entire high-speed railway, and the last hurdle in high-speed railway construction. It involves many disciplines such as disaster monitoring engineering, water supply and drainage, stations, and four-electricity housing engineering. The Four-Electricity Project is a high-speed railway train that obtains electricity from the contact network through the pantograph on the roof to provide power for the train. It is the basis for the operation of high-speed railways, and its technology and standards have very high requirements.

[0003] The engineering quality control of the four power projects is the top priority of construction project management. Since the construction of the four power projects involves many professions, the quality management work is more complicated and difficult to quantify. The construction process must strengthen pre-control, process control and real-time control, discover and solve quality problems in the construction process at any time, and correct quality management trend problems in a timely manner. In addition, there are a large number of power construction project acceptance projects, so the monitoring of the construction quality of the four power projects is particularly important. The traditional monitoring of the quality information of the four power projects mainly relies on manual statistics by managers or the use of office software for statistics, which has problems such as large workload, long time consumption and low accuracy. There is an urgent need for a monitoring system that can help managers objectively, accurately and timely manage and control the quality of the project, realize the closed-loop management of quality problem projects, and provide warning functions to improve the efficiency of quality management.

[0071] Area division unit: Since the four-electricity project serves the high-speed railway construction, the entire project is carried out around the high-speed railway route. This embodiment determines multiple construction nodes on the construction path of the high-speed railway, and uses each construction node as the center and presets a radius to form multiple sub-areas. The quality monitoring of the entire four-electricity project is converted into quality monitoring of multiple sub-areas, and the BIM model is divided into corresponding sub-areas. Different from the previous quality monitoring of different projects of the entire project, the quality monitoring after regional division greatly reduces the amount of monitoring data and the difficulty of monitoring.

[0072] Quality score unit: obtain the quality data of all construction projects in a single sub-area in the BIM model, and process these quality data using the first formula to obtain the quality score of the single sub-area. The first formula is specifically:

[0078] This embodiment also includes obtaining the quality score of any construction project in a single sub-area:

[0079] Obtaining any construction project as a first construction project, and obtaining historical quality data of the first construction project;

[0080] Based on the historical quality data, a plurality of data intervals are divided, each data interval is preset with a quality score value, and the quality score value is proportional to the data interval;

[0081] Acquire actual quality data of the first construction project as first quality data, and acquire a data interval in which the first quality data is located as a first data interval;

[0082] A quality score value corresponding to the first data interval is obtained as the quality score of the first construction project.

[0083] Among them, the quality score unit of this embodiment obtains the quality data of all projects in each sub-area, and then divides the data into intervals and uses preset quality score values ​​to unify the quality judgment standards of the entire sub-area including the construction projects of the entire four-electricity project, and then calculates the quality scores of different engineering projects in a single sub-area and the quality score of the entire sub-area respectively. The set quality score is used as the quality indicator of each sub-area and the construction projects included, which helps the group manager to more intuitively understand the quality status of each sub-area and its construction projects in the entire four-electricity project.

[0084] Quality monitoring unit: obtains all quality scores of a single sub-area within a preset time period to obtain an acquisition result, and based on the acquisition result, establishes a trend graph about the quality score of the single sub-area. Based on the trend graph, by monitoring the quality score within the preset time period, the quality monitoring effect of the entire sub-area is achieved;

[0085] In this embodiment, based on the second acquisition result, establishing a trend graph of the quality score of a single sub-region within the preset time period includes:

[0086] With the time in the preset time period as the abscissa and the quality score of the single sub-region in the preset time period as the ordinate, a trend graph of the quality score of the single sub-region in the preset time period is established.

[0094] Among them, this embodiment constructs a trend graph of the quality score of a single sub-region within a preset time period, and sets a qualified value of the quality score, that is, a quality qualified line, in the trend graph. When it is determined that there is a quality score in the trend graph that is lower than the quality qualified line, a first-level quality warning message is sent to a preset terminal. If all quality scores in the trend graph are higher than the quality qualified line, the preset time period is divided into several continuous time intervals, and then the quality score in each time interval is fitted to obtain the slope of the quality score corresponding to each time interval. When it is determined that the slope of the quality score corresponding to at least two consecutive time intervals is negative, it indicates that the quality of the sub-region is continuously declining at this time, and a second-level quality warning message is sent to the preset terminal.

[0095] Furthermore, this embodiment also provides: if a single sub-area sends a first-level quality warning message, the corresponding sub-area of ​​the BIM model is marked with a color (such as red); if a single sub-area sends a second-level quality warning message, the corresponding sub-area of ​​the BIM model is marked with a color (such as yellow). Similarly, for sub-areas in the BIM model that have no quality warning information, other colors (such as green) are used for marking. This helps managers to intuitively obtain the quality profile of the corresponding sub-areas through the colors of different sub-areas in the BIM.
