Research on dynamic management and control of safety layout for major hazard installations of hazardous chemicals based on high resolution remote sensing

In order to contain the major and extraordinarily serious accidents of hazardous chemicals and solve the problem of space limitation in the traditional safety monitoring methods,the research on the dynamic management and control of regional safety layout for the major hazard installations of hazardous chemicals was conducted by combining the high resolution remote sensing with the numerical simulation technology.Firstly,the key management and control range for the major hazard installations of hazardous chemicals was simulated and determined by using the numerical simulation technology.Secondly,the method of change detection being suitable to the dynamic management and control of safety layout for the major hazard installations of hazardous chemicals was constructed based on the high resolution remote sensing images,so as to dynamically monitor the change situation of buildings,roads and other artificial structures within the safety protection range,and strictly control the density of artificial structures within the accident influence range.Finally,the demonstration application was conducted by taking the Longqiao chemical enterprise in Neijiang as an example.The results showed that the high resolution remote sensing technology could effectively monitor the engineering construction situation within the safety protection range for the major hazard installations of hazardous chemicals,and help the enterprises of hazardous chemicals to maintain the sufficient external safety protection distance and reduce the risk of major and extraordinarily serious accidents of hazardous chemicals.
