[0045] The present application will be further described below in combination with the embodiments and the accompanying drawings.

[0046] At present, regular and targeted learning of workers has been popularized, but in the process of popularization, it is found that most of the workers on site have poor learning ability, so when they need to learn all the content, not only is the efficiency low, but also the workers will have a repulsive psychology, which plays a reverse role. And each worker has his own familiar environment and work type, and continuous learning of workers in familiar environment will further increase the workers' repulsion psychology. It is better to let him spend time on work types in unfamiliar environment or work types that do not meet the requirements in previous evaluation than to let him learn work types in familiar environment, so as to achieve targeted and efficient learning.

[0047] For example: worker A is performing a hot work operation, and the most familiar operating environment is environment A, that is, he is familiar with the materials that cannot be stacked below the hot work place in environment A, or non-operating personnel cannot approach the welding device, so when identifying the behavior of the worker, it is necessary to examine whether the worker stacks the materials according to the requirements, whether he moves within the safety range, in other words, whether the worker violates the operation or illegally enters the prohibited area. If from the start to the end of the project, every time learning, the relevant education content of hot work operation in environment A is pushed to him, he will only choose to take a chance to evade such learning. If he can be pushed to operate corresponding work types in unfamiliar environment every time he learns, such as hot work operation in environment B, it will not only make him have the enthusiasm of learning, but also save his learning time.

[0048] Embodiment 1

[0049] In order to solve the above technical problems, the embodiment discloses a safety education content pushing method for construction site, which specifies different learning plans for each worker. At least the following steps are included:

[0050] As shown in Figure 1 , the safety education library is generated by listing the education materials in a tree structure, and at least one dimension of identification tag is created for each education material to obtain an identification tag set; in this embodiment, the identification tag includes at least three dimensions, namely time node tag, construction stage tag and work type tag based on construction stage. The form of education material includes: video, ppt, picture, voice or other forms.

[0051] Real-name authentication and numbering are performed on the workers to create work information files about the workers; the work information files at least include: current construction stage-work type, date, real-time assessment information;

[0052] A priority pushing model is created, and the pushing keywords required by the workers are obtained based on the work information files; the pushing keywords are mapped to the identification tag set, and the identification tags with mapping relationship with the pushing keywords are matched to obtain a temporary tag set;

[0053] The education material corresponding to the temporary tag set is called in the safety education library to obtain a to-be-pushed education material, and the to-be-pushed education material is pushed to the corresponding worker.

[0054] In a further embodiment, the education material is basic education content, stage education content related to a construction stage, and operation education content related to a work type arranged in parallel. For example, the basic education content is the literacy of each worker, that is, the construction site rules and regulations that need to be familiar to the worker. Such basic education content is sent to all workers at a predetermined time. The stage education content related to the construction stage is the education content about different stages such as the piling stage, concrete pouring, and protective wall construction. The operation education content related to the work type is detailed content, for example, the work type of protective wall construction includes hoisting, high-altitude operation, and welding. For example, the work type of piling also includes welding, but the operation environment of welding for protective wall construction is different from that of piling. When the worker switches from the previous environment to the new environment, whether it is the same work type or different work types, there will be a certain period of adaptation stage. In the adaptation stage, the worker may lack safety awareness or have poor behavior ability due to unfamiliarity with the environment, so the same education content cannot be used. Therefore, in order to distinguish the education content required by the operation criteria and requirements of the same work type in different construction stages and different construction environments, the identification tag is refined to a construction stage tag and a work type tag based on the construction stage when creating the identification tag.

[0055] In a further embodiment, the work information file of the worker is authenticated by real name, that is, each worker has a corresponding work information file, and the purpose is to facilitate management and accurate education pushing based on the previous performance of the worker.

[0056] In this embodiment, the learning content of the construction stage in which the worker is currently located must be pushed, and the construction stage in which the worker has low safety awareness or / and poor safety behavior ability is selected for pushing according to the previous assessment of the worker. Therefore, in this embodiment, the creation process of the priority pushing model is as follows:

[0057] Real-time assessment information set A is created in the work information file r {A1,A2,…,A t-1 ,A t}, where t represents the current construction stage, A t-1 represents the assessment information of the historical construction stage, and A t represents the assessment information of the current construction stage.

[0058] The A1,A2,…,A t-1 ,At respectively t are compared, and the weight values ω t are calculated in turn a = arg min{ω1,ω2,…,ω t-1} to screen out the construction phase in which the worker has low safety awareness or / and poor safety behavior ability; wherein the calculation formula of the weight value is as follows: In the formula, a is a credibility factor.

[0059] Based on the construction phase in which the worker has low safety awareness or / and poor safety behavior ability, historical keywords are refined, and real-time keywords are refined based on the construction phase at the time, so that the historical keywords and the real-time keywords constitute the push keywords. If the worker has two construction phases in which he has low safety awareness or / and poor safety behavior ability before this time, the value of a is 2, that is, the last two values are selected from ω1,ω2,…,ω t-1 . Then the historical keywords are two, so the push keywords are three. The keywords include the type of work and the corresponding phase, so as to realize accurate scheduling of the education content.

[0060] However, the following situation may also occur: the worker actually meets the evaluation standard of the current construction phase, and he should learn the construction phase in which he has low safety awareness or / and poor safety behavior ability before this time. Therefore, after the refinement of the push keywords is completed, the embodiment also sets the sorting of the push keywords, that is, the push order is determined: the weight values ω a of the construction phase in which the worker has low safety awareness or / and poor safety behavior ability in the historical construction phase and the current construction phase are sorted in ascending order to obtain the push order, and then the push of the related education materials is performed according to the push order.

[0061] For example: the current construction phase of the worker B is protective wall maintenance, and the evaluation meets the standard. However, he did not meet the standard in the welding phase before this time, and he was poor in the welding phase before this time, and the keywords about the welding phase were refined by the priority push model before this time. However, if the push sorting is not performed, the worker B may first receive the education content about the protective wall maintenance, and when he has finished learning this content, he has lost the patience to continue to learn the education content about the welding phase pushed by the push, which may lead to a vicious cycle. Therefore, the push keywords are sorted, and after the sorting, the education content about the welding phase is pushed in priority to the education content about the protective wall maintenance.

[0062] The above expressions are all for the push relationship generated in the construction phase, and part of the education content is not limited to the construction phase and the type of work, which is applicable to the entire project. Therefore, for such education content, the priority push model of the embodiment further includes: when the construction time of the current construction phase falls within the time node label, the priority push model sets the education material corresponding to the time node label as the optimal level and pushes it to the corresponding worker.

[0063] When there is a sudden change in air temperature or weather anomaly, the priority push model sets the education material corresponding to the weather label as the optimal level and pushes it to the corresponding worker.

[0064] In other words, the time dimension, i.e. holidays, spring, summer, autumn and winter, is also added when creating the label. Because the construction project is a project that takes a long time to complete, it may span at least one year, and during this long period, holidays will be encountered. Therefore, in order to increase the safety of the construction site during the holidays, it is necessary to push related equipment inspection, construction site power failure, etc. education content before the holiday. At the same time, after the resumption of work, it is also necessary to push the content to make the workers enter the working state as soon as possible. Or during this long period, at least one spring, summer, autumn and winter will be encountered, and some equipment or some types of work on the construction site will have different notes based on the different air temperature. Therefore, it is necessary to push related content to workers when the season changes.

[0065] Similarly, when the weather is about to change, it is necessary to push related education content to workers after receiving the weather warning, and to prepare in advance, which is to protect the safety of the construction site and the equipment, as well as the safety of the workers themselves. For example, when the weather warning is that there will be gale and storm, lightning and thunder in the next 6 hours, the related content on how to deal with gale and storm, lightning and thunder is pushed to the workers. Or when the weather warning is that the temperature will drop to below zero in the next few days, the workers are pushed to the related content on how to keep warm themselves and the related equipment and materials. Therefore, the weather dimension is also added when creating the label.

[0066] It should be noted that the material received by each worker about the same label may be different because the worker belongs to different construction phases and types of work. Similarly, the mapping relationship of the push keyword and the identified label needs to conform to the current construction phase-work type keyword.

[0067] In a further embodiment, the mapping relationship between the push keyword and the identified label is as follows:

[0068] Define the push keyword as G = {G1, G2, …, G n}, where n is the number of push keywords; based on each push keyword, generate a corresponding sequence string G m = {N1, N2, …, N m}, wherein m is the number of push keyword sequence strings;

[0069] define each identification tag sequence string as L={L1, L2, …, L j}, wherein j is the number of identification tag sequence strings;

[0070] respectively calculate the index value of the push keyword sequence string ρ G and the index value of the identification tag sequence string ρ L When |ρ G -ρ L |∈[0, δ], it meets the mapping relationship, wherein δ is a pre-set threshold. wherein x is an approximation parameter.

[0071] According to the present application, learning content corresponding to the current construction phase of the worker is pushed; at the same time, according to the previous assessment standard of the worker, the learning content required for the corresponding construction phase of the worker is pushed by using the priority push model, so that the push effect is efficient and high in precision, greatly reducing the learning time of the worker while also making up for the defects of the worker.
