Embodiment 1
[0078] Taking a certain construction project as an example, the implementation process of the construction safety monitoring method based on CNN convolutional neural network according to the present invention is as follows, as figure 1 shown, including:
[0080] In this project, 30 different operators were surveyed and the sensors were arranged to measure the data of the operators; at the same time, the sensors were arranged to measure the data of the working environment; and the data of safety management measures were obtained through safety checklists and on-site investigations.
[0081] For the operator data, part of it is collected through safety questionnaires, including the operator’s age, weight, vision, hearing, work experience, education experience, economic status, and heart disease history; the other part is collected in real time through sensors, including the operator’s body temperature , heart rate, blood pressur...
Embodiment 2
[0107] As another example, this time, the safety evaluation data of randomly arranged operators, working environment, construction site safety management and safety measures in step S3 described in Example 1 are rearranged, and the random arrangement of evaluation indicators is no longer used but the The evaluation indicators with high importance are moved to the middle, and the evaluation indicators with low importance are moved to the surrounding matrix, because during the movement of the convolution kernel function, the number of data extractions in the surrounding borders is less, and the data except for the surrounding borders The number of extractions is high.
[0108] According to the model trained in Example 1, output several of the trained convolution kernel functions, observe the size of the convolution kernel function and select a larger value in the convolution kernel function, and extract its corresponding evaluation index. For Example 1, it is obtained that a val...

Abstract
The invention discloses a building constructionsafety monitoring method based on a convolutional neural network. The building constructionsafety monitoring method based on the convolutional neural network comprises the following steps: 1) obtaining safety management measure data of operators, operation environments and building construction sites, obtaining a safety evaluation grade, and forminga training set and a test set of a CNN convolutional neural network model through preprocessing; 2) taking data of operators, operation environments and safety management measures in the training setas input, taking safety evaluation levels as output, determining a safety monitoring index arrangement mode and a CNN convolution neural network kernel function through training, and storing a trained CNN convolution neural network model; and 3) predicting the safety of the operator and the operation environment. The building construction safety monitoring method overcomes the defects that an existing monitoring method is inaccurate in problem evaluation result, and the evaluation factor of the evaluation method is single, and the calculation cost is high, and real-time monitoring cannot be achieved.
Description
technical field [0001] The invention belongs to the field of building construction safety evaluation, and in particular relates to a building construction safety monitoring method based on a convolutional neural network. Background technique [0002] With the advancement of production technology and in order to meet the needs of life, the construction industry has developed rapidly, and the number of employees in the construction industry has increased year by year in recent years. But at the same time, construction safety accidents are also the types of accidents with a high fatality rate. A construction safety monitoring method is proposed, which is of great significance to the prevention of safety accidents. [0003] Nowadays, there are many problems in the construction safety monitoring and evaluation methods: First, the monitoring and evaluation indicators are too single, such as the man-to-man stand-by method, the placement of monitoring cameras, and the simple sensor...
