Description
Technical Field
The invention relates to the technical field of chemical accident situation information distribution, in particular to a chemical accident situation information distribution method and system facing to terminal decision requirements.
Background
At present, about 676 chemical industry parks which are mainly petrochemical industry and fine chemical industry in China are developed, and large-scale chemical industry parks, refining and chemical integration projects and ultra-large petrochemical bases are developed on an initial scale and are extremely rapid. However, due to the uneven safety management level of the chemical industry in China, the large-scale device, the complicated process and the production integration enable the scale and the severity of serious accidents to be increased steeply, and great challenges are brought to emergency rescue of the accidents.
In a very large chemical accident rescue site, the terminal decision demand refers to the situation perception of a first-line commander on the key situation of the chemical accident and the fine-grained information demand of the inter-situation evolution rule of the first-line commander on the tactical execution layer. As a terminal decision group of a complex chemical accident rescue site, the timeliness and the scientificity of the decision determine the success or failure of the whole rescue work, and the dependency degree on disaster site information is high. On the other hand, in the major chemical accident rescue scene, because the terminal decision-making groups are in different geographic spatial environments, the situation faced in the same time period may have significant difference, the key points of the decision and the requirements for information are essentially different from those of other level command groups, and the current extensive chemical accident emergency command information management mode cannot adapt to the major chemical accident emergency rescue requirements. Therefore, a fine-grained information reconstruction and distribution method facing to the terminal decision-making requirement is a key problem which is urgently needed to be solved by the current chemical accident emergency rescue.
In a very large chemical accident rescue site, terminal decision users in different space-time environments have different urgent degrees on situation information requirements, and have specific requirements on time delay and reliability of information transmission. In the face of the emergency rescue of the serious chemical accident, key problems to be solved urgently during information distribution mainly include a field information classification and classification method, and information distribution rules and algorithm realization. The existing information distribution research mainly focuses on the fields of military operations and internet, and the distribution method includes a distribution method based on a publish/subscribe mode and a distribution method based on active services/demands. The distribution method based on the publish/subscribe mode mainly adopts a channel-based, subject-based, content-based or type-based matching method to match and distribute information according to the interests or personalized information requirements of users, and the method is actually a passive information distribution mode. The information distribution method based on service/demand response selectively distributes information with high matching degree to different users by constructing a matching rule base between the information distribution method and the users according to the requirements or service items preset in advance by the users. Thus, the method is actually an active information distribution mode. However, the information distribution method in the fields of military operations and internet is fundamentally different from the chemical accident emergency decision command in the aspects of information classification composition, information acquisition and transmission mode, demand mode, situation understanding, perception application and the like, and is difficult to be directly applied to chemical accident emergency rescue.
