Further, the embodiment of the application further comprises:
step S410: traversing the historical accident set, and extracting an accident induction factor set;
step S420: carrying out relevance analysis on the animation associated knowledge points based on the accident induction factor set to obtain an associated accident set, wherein the associated accident set comprises an associated induction factor and an accident security level;
Step S430: taking the association induction factor as a first standard answer, and constructing a first case question based on the association accident;
step S440: taking the animation associated knowledge points as second standard answers, and constructing a second case question based on the associated induction factors;
step S450: arranging the first case question and the second case question in sequence, and setting the first case question and the second case question as interactive question-answer clauses of any one of the animation associated knowledge points;
step S460: traversing the animation associated knowledge points according to the accident security level and the interaction clause quantity threshold value to perform clause quantity distribution, and obtaining a clause quantity distribution result of any one animation associated knowledge point;
step S470: and expanding the interactive question-answer clauses of any one of the animation associated knowledge points according to the clause quantity distribution results, and adding the interactive question-answer clauses into the first interactive question-answer sentence.
Specifically, the historical accident set stores various safety accident cases, the occurrence of the cases has the induction factors, the whole historical accident set is traversed, the induction factors of each case are extracted and are summarized into accident induction factor sets, such as the condition that safety helmets are not worn, the safety precaution of high-altitude construction is not in place, the safety of constructors is not noticed, and the like, and a basis is provided for carrying out association analysis on the knowledge points associated with the animation.
Based on each factor in the accident-inducing factor set, it is determined which knowledge points of the animation-associated knowledge points are associated, such as that the helmet is not worn and the helmet must be worn at the construction site. Meanwhile, the corresponding safety level of the caused accident case is judged, and if the high-altitude object is dropped, serious injury and even death are caused, the related accident set is formed. The security level is divided according to the severity of the accident, such as level 1: light injuries such as skin trauma, minor abrasion, etc.; level 2: serious injuries, such as fracture, concussion, etc., require hospitalization; level 3: heavy injuries require a longer time for healing; level 4: serious injuries such as high paraplegia, loss of physiological functions, etc.; level 5: death injuries. The security level may be determined as: the high-altitude falling object causes losing physiological functions, and the safety level is 4; mechanical compression results in amputation with a safety rating of 3; electrocution resulted in death with a security level of 5. When the interactive question-answer sentence is constructed, different clause numbers are set according to the security level, and the higher the level is, the more clauses are, so that important and high-risk knowledge points are strengthened.
And constructing a first case question based on related accident cases by using a first standard answer of the related induction factors, wherein the first case question is used for 'Zhang Sanniao Zhaozhaozhaozhu' for working and driving without wearing a safety helmet, and is injured by falling objects of engineering building and hospitalized. What is the main reason for this accident? The option is the relevant evoked factor, and the correct option is the relevant evoked factor. With the animated relevant knowledge points as second standard answers, a second case question is constructed based on the relevant evoked factors, such as "if you are Zhang Santa what is done? And the second standard answer is the second standard answer when the safety helmet is worn in the options. And respectively examining the understanding of the user to the safety knowledge in two aspects by using the association induction factors and the animation association knowledge points. The first case question sentence and the second case question sentence are arranged in sequence and are set as interactive question-answer clauses of certain animation associated knowledge points, and each knowledge point corresponds to a plurality of clauses.
And traversing the animation associated knowledge points, and summing the security levels of the associated accidents corresponding to the animation associated knowledge points to obtain the total security level. For example, the accident security levels corresponding to the "high-altitude object", "necessary-to-wear safety helmet" and "homing of construction equipment" are respectively: level 4, level 3, level 2, and add to get a total security level of 9. Then, the ratio of each accident security level to the total security level is calculated, for example, level 4 is 4/9=44.4%, level 3 is 3/9=33.3%, and level 2 is 2/9=22.2%. And obtaining the clause number corresponding to each accident security level according to the duty ratio and the preset clause number. For example, if the preset number of clauses is 20, the number of clauses corresponding to the "high altitude weight" is 44.4% ×20=9, the number of clauses corresponding to the "necessary to wear safety helmet" is 33.3% ×20=7, and the number of clauses corresponding to the "building equipment homing" is 22.2% ×20=4, so as to obtain the number of clauses of each associated knowledge point.
The method comprises the steps of extracting the induction factors in the historical accident set, carrying out association analysis with animation associated knowledge points, constructing corresponding question-answer clauses, controlling the number of the knowledge point clauses according to the accident security level and the clause number threshold value, and finally forming a first interactive question-answer sentence, so that the knowledge points are effectively corresponding to typical accident cases, and the education effect is improved.
Further, the embodiment of the application further comprises:
step S421: inputting any accident induction factor set and any animation associated knowledge point into an induction probability analysis model to obtain an induction probability evaluation result;
step S422: and when the evoked probability evaluation result is greater than or equal to an evoked probability threshold, adding the historical accidents corresponding to the accident induction factors into the associated accident set of the animation associated knowledge points.
Specifically, the evoked probability analysis model adopts a neural network model, such as a multi-layer perceptron model, an LSTM model, a GRU model and the like. The model is learned and trained by setting model super-parameters including learning rate, iteration times, node number, layer number and the like and utilizing a large number of training samples including accident induction factors, animation associated knowledge points and whether related accidents are actually caused by the accident induction factors and the animation associated knowledge points, and the corresponding relation between the accident induction factors and the animation associated knowledge points is learned by the model in the training process, so that the model obtains the capability of evaluating whether potential association exists between the accident induction factors and the knowledge points or not, and the association between the accident induction factors and the animation associated knowledge points is evaluated by using an induction probability analysis model.
And running the model obtained by training on the new data, inputting accident induction factors and animation associated knowledge points, and obtaining the associated probabilities of the accident induction factors and the animation associated knowledge points as output results, wherein the output results are induction probability evaluation results. Such as entering any one of the accident-inducing factor sets into the model, such as overhead work, equipment failure, and any one of the animation-associated knowledge points, such as having to examine the equipment. The model judges whether potential association exists between the training weight and the threshold value, if so, an evoked probability evaluation result is output, and if the evoked probability is 85%, the accident induction factor and the knowledge point have higher probability to cause related accidents.
