Detailed Description
The invention is further described with reference to the following examples and the accompanying drawings.
At present, regular and targeted learning by workers has become popular, but in the process of popularization: most workers on site have poor learning ability, so that when they need to learn all the contents, the efficiency is low, and the repulsive psychology of workers is in reverse. And each worker has the work category under the familiar environment, the exclusive psychology of the worker can be further increased when the worker continuously learns the work category under the familiar environment, and the worker is not better than the worker who learns the work category under the more familiar environment, so that the worker can spend time on the work category under the less familiar environment or the work category which is not qualified before evaluation, and the targeted and efficient learning is realized.
For example, the following steps are carried out: when worker a performs a fire operation, the most familiar operating environment is environment a, i.e., he is familiar with the fact that materials cannot be stacked under the fire in environment a, or that non-operators cannot approach the welding apparatus, and therefore, when identifying the behavior of the worker, it is necessary to investigate whether the worker stacks the materials as required, performs an activity within a safe range, in other words, whether the worker is performing an illegal operation or breaking into an prohibited area without permission. If every learning pushes the relevant educational content of the fire work in environment a to him from the start to the end of the project, he will only choose to make an opportunity to get an ingenious way to escape such learning. If the corresponding work category can be pushed to the unfamiliar environment every time of learning, the operation is better than the fire operation in the environment B, so that the enthusiasm of the user in learning is generated, and the learning time is saved for the user.
Example 1
In order to solve the above-described technical problem, the present embodiment discloses a safety education content push method for a construction site, in which different learning plans are specified for each worker. At least comprises the following steps:
as shown in fig. 1, listing education materials in a tree structure to generate a secure education library, and creating an identification tag of at least one dimension for each education material to obtain an identification tag set; in this embodiment, the identification tag at least includes three dimensions, which are a time node tag, a construction stage tag, and a work category tag based on a construction stage. Forms of educational material include: video, ppt, picture, voice, or other forms.
Performing real-name authentication and numbering on workers, and creating a work information file about the workers; the work information file at least comprises: the current construction stage comprises work type, year, month and day and real-time assessment information;
creating a priority pushing model, and obtaining pushing keywords required by workers based on the work information file; mapping the push keywords to an identification tag set, and matching identification tags which have a mapping relation with the push keywords to obtain a temporary tag set;
and calling the education materials corresponding to the temporary label sets in the safety education library to obtain education materials to be pushed, and pushing the education materials to be pushed to corresponding workers.
In a further embodiment, the educational material is basic educational content, stage educational content related to construction stages, and operation educational content related to work categories, which are arranged in parallel. For example, the basic education content is the literacy of workers each worker should have, i.e., the construction site regulations and the like that the worker is required to be familiar with. Such basic education contents are collectively transmitted at a predetermined time. The stage education contents related to the construction stage are education contents related to different stages of piling stage, concrete pouring, guard wall construction and the like. The operation education content related to the work type is a refined content, for example, the protective wall is constructed, and the work type comprises hoisting, overhead operation, welding and the like. Taking piling as an example, the work types of the piling also include welding, but the operation environment of the welding for constructing the protective wall and the welding for piling is different, and workers switch from the previous environment to the new environment, and no matter the workers operate in the same work type or different work types, there will be a certain time of self-adaptation stage, and in the self-adaptation stage, the workers may not be familiar with the environment, so that the problems of lack of safety consciousness or poor behavior ability and the like are caused, and therefore the same education content cannot be used. Therefore, in order to distinguish that the education contents required by the same work type in different construction stages and different construction environments are not the same, the identification tags are refined to construction stage tags and work type tags based on the construction stages when the identification tags are created.
In a further embodiment, the work information files of the workers are certified by real names, that is, one worker has a corresponding work information file, which aims to facilitate management and accurate educational delivery based on the previous performance of the worker.
In this embodiment, the learning content of the worker at the current construction stage needs to be pushed, and meanwhile, according to the previous assessment of the worker, a construction stage where the worker has low safety awareness or/and poor safety behavior capability is selected in a targeted manner for pushing, so in this embodiment, the creation process of the priority pushing model is as follows:
in the work informationRespectively creating real-time assessment information sets A in files r {A 1 ,A 2 ,…,A t-1 ,A t Where t denotes the current construction stage, A t-1 The assessment information of the historical construction stage is represented; a. the t Then representing the assessment information of the construction stage at that time;
the A is added 1 ,A 2 ,…,A t-1 ,A t Respectively corresponding to the assessment criteria S t Comparing, and sequentially calculating weight value omega t By the formula A a ＝arg min{ω 1 ,ω 2 ,…,ω t-1 Screening out a construction stage with low safety awareness or/and poor safety behavior capability of workers in a historical construction stage; the formula for calculating the weight value is as follows:
in the formula, alpha is a credible factor.
Historical keywords are obtained by extraction based on the construction stage with low safety consciousness or/and poor safety behavior capability, real-time keywords are obtained by extraction based on the construction stage at that time, and the historical keywords and the real-time keywords form pushing keywords. If the former construction stage of the worker with low safety consciousness or/and poor safety behavior capability is two, the value of a is 2, namely in omega 1 ,ω 2 ,…,ω t-1 The last two values are selected. The number of history keywords is 2, so the number of push keywords is 3. The keywords comprise work types and stages corresponding to the work types, and accurate scheduling of education contents is achieved.
However, the following may also occur: the assessment criteria of the construction phase in which the worker is currently located are actually up to standard, compared with the condition that the worker should go to the construction phase before learning, in which the safety consciousness is low or/and the safety behavior capability is poor. Therefore, after the refinement of the pushed keywords is finished, the embodiment further sets to sort the pushed keywords, that is, determine the pushing sequence: obtaining a weight value omega corresponding to a construction stage and a current construction stage in which a person has low safety consciousness or/and poor safety behavior capability in a historical construction stage a From small to largeAnd sequencing in a fixed sequence to obtain a pushing sequence, and pushing related education materials according to the pushing sequence.
For example, the following steps are carried out: and the current construction stage of the worker B is the maintenance of the protective wall, and the examination meets the standard. While his examination in the previous welding phase is not qualified and poor, keywords related to the welding phase are extracted through a priority push model before, but if the push ordering is not performed, it is likely that worker B receives the education contents related to the maintenance of the protective wall first, and when he learns the contents, he loses patience to continue learning the pushed education contents related to the welding phase, a vicious circle is caused. Therefore, the pushing keywords are ranked, and the education content related to the welding stage is pushed in preference to the education content related to the maintenance of the protective wall after ranking.
The above expressions are all the push relations generated for the construction phase, and some education contents are not limited to the construction phase and the work category, and it applies to the whole project, so for such education contents, the priority push model of the embodiment further includes: and when the construction time of the current construction stage falls into the time node label, the priority pushing model sets the education materials corresponding to the time node label to be in the optimal level and pushes the education materials to corresponding workers.
When sudden change of air temperature or abnormal weather exists, the priority pushing model sets the education materials corresponding to the weather tags to be in the optimal level and pushes the education materials to corresponding workers.
In other words, time dimensions, namely holidays, spring, summer, autumn, winter and year, month and year are added when the label is created. Because a construction project is a project that can be completed for an extended period of time, it may span at least 1 year, and during this extended period of time, a holiday, is encountered. Therefore, in order to increase the safety of the construction site during the holiday, education contents such as equipment inspection, construction site power-off and the like need to be pushed before the holiday. Meanwhile, after the rework, the content for the worker to enter the working state as soon as possible needs to be pushed. Or at least one spring, summer, autumn and winter can be met in the longer time, and the attention items of some equipment or some work types on the construction site are different based on the difference of air temperature. Therefore, it is necessary to push related contents to workers when season changes occur.
Similarly, when the weather is about to change suddenly, after the weather early warning is received, related education content needs to be pushed to workers, preparation is made in advance, and the safety of a construction site and equipment and the safety of the workers are protected. For example, when the weather warning is that in the future 6 hours, the weather storm and lightning thunder will occur, the worker is pushed about how to deal with the weather storm and lightning thunder. Or when the weather early warning is that the temperature will be greatly reduced to below zero in the next few days, the worker is pushed how to carry out heat preservation treatment on related equipment and materials and keep warm per se. The weather dimension is also added when creating tags.
It should be noted that the material received by each worker for the same tag may be different because the construction stage and the type of work to which the worker belongs are different. The mapping relationship of the keywords meeting the current construction stage-work type is also needed.
In a further embodiment, the mapping relationship between the push keyword and the identification tag is as follows:
defining a push keyword as G ═ G 1 ,G 2 ,…,G n N is the number of the push keywords; generating a corresponding sequence string G based on each of the push keywords m ＝{N 1 ,N 2 ,…,N m M is the number of the keyword sequence strings;
defining a sequence string for each identification tag as L ═ L 1 ,L 2 ,…,L j J is the number of identification label sequence strings;
respectively calculating index values rho of the sequence strings of the push keywords G And an index value ρ identifying a tag sequence string L When | ρ G -ρ L |∈[0,δ]Then the mapping relationship is satisfied, where δ is a preset threshold.
Where x is an approximation parameter.
The method comprises the steps of pushing learning contents corresponding to a construction stage according to the construction stage where a worker is currently located; meanwhile, according to the assessment standard of workers before, the learning content required by the corresponding construction stage with poor assessment before the workers is pushed by using the priority pushing model; accomplish high-efficient and the propelling movement effect that the precision is high, greatly reduced workman study time can also compensate workman's partial defect simultaneously.
