Embodiment Construction
[0041] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.
[0042] Whether it is food safety, public health safety, school safety, etc., a certain safety early warning mechanism is required. In terms of food safety, if the food produced by a certain company does not meet the standards, it is easy to cause many safety problems. For example, the quality of milk powder did not meet the standard, resulting in many babies with big heads and severe malnutrition. Therefore, safety supervision and early warning of these manufacturers can effectively prevent safety accidents from happening again. At present, the prediction and warning of safety accidents ...

The invention discloses an alarm method and device for short, medium and long-term risks, and the method comprises the steps: obtaining a feature vector of a risk alarm target through word embedding, inputting the feature vector of the risk alarm target into a convolutional neural network, extracting a target portrait feature vector of the risk alarm target, obtaining a time sequence feature vector according to a monitoring data sample corresponding to a risk accident of an object which has multiple times of risk accidents every time, performing recursive operation on the time sequence feature vector by adopting a recursive neural network model, and extracting a risk tendency feature vector; and finally, fusing the target portrait feature vector and the risk tendency feature vector, inputting the fused target portrait feature vector and the risk tendency feature vector into a full-connection neural network model, predicting a risk value corresponding to a risk alarm target, and giving an alarm when the risk value is greater than a preset threshold value. The method and device effectively improve the prediction precision of the recurrent risk, innovate a short, medium and long-term risk assessment method system, and promote the short, medium and long-term risk assessment efficiency and the intelligent level.
Description
technical field [0001] The present application belongs to the technical field of production safety, and in particular relates to a short, medium and long term risk warning method and device. Background technique [0002] Safety has always been an important part of production and social stability. Failure to pay attention to safety will often bring huge costs. Safety is not only reflected in safe production, but also in all aspects of social life, such as fire safety, traffic safety, handling of dangerous goods, public security, stampede incidents and so on. [0003] "Safety first, prevention first" is the basic policy of production safety in my country. How to give early warning and eliminate safety hazards has always been the top priority. Safety early warning and supervision and inspection work are the main means and measures of "prevention first". [0004] At present, the early warning of safety is often pre-judged according to various hazards before the incident. When m...
