Sudden disaster emergency remote sensing control system and method

Abstract

The invention belongs to the technical field of information retrieval and a database structure thereof, and discloses a sudden disaster emergency remote sensing control system and method, and an information data processing terminal. A typical geological disaster area is selected in Human to perform demonstration application and model exercise to solve the establishment of geological disaster emergency response mechanisms under different levels, different types and different geographical environments; and a complete and mature geological disaster emergency investigation technical process is formulated by using the disaster emergency remote sensing investigation data acquisition technology, a disaster information extraction method and application capability, and a foundation is laid for thepromotion and application of a sudden disaster emergency remote sensing investigation system to the geological disaster emergency investigation work. Database construction before geological disasters,establishment of the emergency response mechanism, rapid acquisition of geological disaster data, image data processing, interpretation and extraction of geological disaster information and establishment of the sudden disaster remote sensing emergency response system constitute the key technologies of the project.

Description

technical field [0001] The invention belongs to the technical field of information retrieval; and database structure thereof, and in particular relates to an emergency remote sensing control system and method for sudden disasters. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: the application of remote sensing technology to record disaster information can be traced back to the beginning of the last century. In 1906, Lawrence used a kite as a platform to carry a camera to successfully photograph the scene after the San Francisco earthquake, which was the beginning of human beings using remote sensing technology to record earthquake disaster information. Subsequently, the United States, Japan, and the European Community gradually applied remote sensing technology to disaster research. In the mid-1970s, the United States took the lead in carrying out research on the application of environmental satellites in di...

Problems solved by technology

(2) The rapid processing of remote sensing data is not ideal. The rapid development of remote sensing technology, but the speed of data post-processing and mapping is generally not ideal, which has become a bottleneck restricting its application in geological disaster emergency investigation.

On the one hand, the large amount of data requires a high configuration of data processing hardware equipment; on the other hand, it generally needs to cooperate with other data for precise geographic positioning, and the data processing speed is slow when the accuracy is high, especially when the low-altitude remote sensing system uses non-measurement civilian images. There is a certain distortion. On the other hand, because there is no POS system installed, the data processing method of direct geolocation cannot be carried out. In addition, there is also a lack of data processing software platform based on parallel computing.

These all restrict the speed of post-processing data

(3) A complete and mature emergency investigation technical process has not yet been formed. A complete remote sensing emergency investigation technical process includes: emergency investigation plan for sudden geological disasters, equipment and personnel configuration, equipment installation and commissioning, data acquisition technical scheme design, A series of business processes such as data acquisition, data processing, result submission, quality control indicators, etc.

(5) The remote sensing emergency investigation and investigation information network sharing platform for geological disasters has not been established. Judging from the remote sensing emergency investigation work of the Wenchuan earthquake and Zhouqu debris flow, there are deficiencies in remote coordination and data sharing. There is still a need for continuous improvement in terms of networkization and networking

[0007] (4) The emergency investigation demonstration station has not yet been established;

[0008] (5) The remote sensing emergency investigation and investigation information network sharing platform for geological disasters has not yet been established

One is that the affected people urgently need help, and the other is that secondary disasters may continue to swallow the lives of survivors
