Description
Technical field
The present invention relates to a kind of chemical hazard prediction precaution and control system, belong to chemicals harm prevention and control technical field.
Background technology
Along with coming into force of Chemical Weapons Convention; Directly use the possibility of chemical weapons to reduce in the war; But cause the possibility of chemical hazard to increase through attacking chemical facility in the war; Like the petrochemical complex facility of NATO's attack Pan Qiewo of the Federal Republic of Yugoslavia in the Kosovo War, its consequence and influence are not second to direct use chemical weapons; Moreover still have a large amount of chemical weapons also not destroy at present, the threat of chemical warfare also still exists.In addition, along with the situation of the chemical attack of terrorism is severe day by day, the pattern variation that chemistry is terrified, for example Japan's " Tokyo subway sarin incident " makes a stir all over the world, and the difficulty of anti-chemical terrified task increases.In recent years, China's chemical accident incidence is in rising trend, and for example the explosion accident of the former chemical general factory chlorine pot in sky, Chongqing makes a very bad impression, and Qiqihar " 8.4 " toxic agent incident of leakage receives much concern.The event frequency life that takes place frequently of hurting sb.'s feelings of particularly Japanese abandoned chemical weapon, its work of treatment is very urgent, and the task of chemical accident emergency management and rescue is urgent day by day and heavy.Above-mentioned these incidents have been beaten alarm bell to people from different perspectives.Therefore, all chemical hazards that chemical warfare, the chemical attack of terrorism, the public chemical event of burst and day something lost chemical weapons etc. caused are taken precautions against with control has important strategic meaning and realistic meaning.
The strick precaution of chemical hazard mainly comprises with control to be carried out emergency disposal and potential chemical risk is carried out prevention and control chemical accident.Implement the strick precaution and the control of chemical hazard for science, must at first carry out the prediction of chemical hazard, then based on predicting the outcome and endanger index system and carry out early warning, and according to the early warning information control of meeting an urgent need.
Chemical hazard prediction precaution and optimal control relate to a plurality of subjects, a plurality of professional domain; Must make up a technology platform; Satisfy ageing and commander's the intuitive and the validity needs of randomness, the decision-making in complicacy, the place of the on-the-spot underlying surface of battlefield and emergency disposal; A main difficult problem below existing at present: the meteorological field at (1) battlefield, emergency disposal scene is complicated and changeable; The meteorological field numerical forecasting is consuming time very long, and present technical merit can not satisfy battlefield and the on-the-spot complicated underlying surface condition and the emergent ageing demand of predicting early warning and control of emergency disposal; (2) for the emergent prediction of the chemical hazard early warning after the incident generation, adopt existing method can not satisfy the needs of operation, training and emergency disposal; (3) to moving emergent in real time prediction early warning of risk source and a plurality of fixedly risk source stalking row chemical hazard and control, still not relevant mature technology; (4) in operation or emergency management and rescue, how optimum emergent controlling schemes is provided in real time, it is minimum that chemical hazard is dropped to, and do not have ripe method at present; (5) how real-time intelligent ground does not also have practical system platform for the emergency command decision-making provides technical support to the analog result of emergent prediction early warning and control.
About an above-mentioned difficult problem, though some correlative studys are arranged both at home and abroad, also there is not the achievement of system, practicality, almost be blank particularly to the research of moving emergent in real time prediction early warning in risk source and a plurality of fixedly risks source and optimal control.
The prior art that the present invention relates to has: MM5; RAMS; CDM; FPPS and adjoint mode.
MM5 (Mesoscale Model 5; Mesoscale model) is the 5th generation mesoscale weather forecast pattern of developing jointly by American National atmospheric research center and Pennsylvania State University; Ability with multinest ability, non-static(al) dynamic mode and four-dimensional assimilate; And can on computer platform, move, can be widely used in atmospheric science research, be particularly suitable for simulating or forecasting the general circulation of mesoscale and regional scale.
RAMS (Region Atmosphere Model System, regional atmospheric pattern) is a three-dimensional, nonfluid static(al), compressible region atmospherical model.The dynamical frame of pattern is non-hydrostatic, original equation mesoscale model; This pattern is to be grown up by nineteen seventies Cotton mesoscale power system that proposes and mesoscale and the land face trait model that microphysical processes pattern and Pielke develop, and has multi-usage, multi-functional characteristics.At present; The object that the RAMS pattern can be simulated comprises on wind spout, thunderstorm, cumulus, the non-homogeneous face of land mesoscale phenomenons such as mesoscale air motion under eddy current, non-homogeneous underlying surface ground atmosphere interaction and power and heating power force in the convective boundary layer; Even turbulent flow and buildings in wind-tunnel small scale on every side streams phenomenon, and can select the simulation tool of RAMS as city local yardstick atmospheric environment sports ground for use.
CDM (Concentration and Dose Model or the toxic Clouds Diffusion Modelover complex terrain, chemical hazard evaluation profile on the complex-terrain) is that Antichemical Command Engineering College P.L.A. is yellow along three-dimensional atmospheric dispersion model on the complex-terrain based on Monte Carlo principle of auspicious foundation.This dispersal pattern is under the support of weather forecast pattern and source strength pattern, and prediction is to the noxious material concentration of dangerous matter sources and the spatial and temporal distributions of dosage.The CDM advantage is apparent in view in closely simulating.
FPPS (Fast Pollution Predication System, fast pollution prediction system) is a three-dimensional atmospheric dispersion model on the complex-terrain based on the Euler principle set up of the Li Lei of Shenzhen weather bureau.This dispersal pattern is under the support of weather forecast pattern and source strength pattern, and prediction is to the noxious material concentration of dangerous matter sources and the spatial and temporal distributions of dosage.FPPS has superiority when yardstick is big.
Adjoint mode is that people such as the Liu Feng of Antichemical Command Engineering College P.L.A. use adjoint method, the dispersal pattern based on CAMx of foundation; This adjoint mode is under the support of weather forecast pattern and source strength pattern, and prediction is to the density of infection spatial and temporal distributions of protection target.A kind of adjoint method that people such as Liu Feng introduce in document " the toxic gas leakage incident being carried out hazard evaluation with adjoint method " (Chinese safe and scientific journal, 2003 the 13rd volume the 9th phase) calculate fast moving chemical risk source in any position the method to the potential hazard degree of protection target.CAMx (Comprehensive Air quality Model with extensions) is the troposphere chemistry transmission Euler type numerical model of U.S. ENVIRON company exploitation; Advection in order to atmosphere pollution (ozone, gasoloid, toxic gas etc.); Diffusion, sedimentation and complicated chemical process.
