Research On Multi-sensor Data Acquisition And Exchange System In Space Information Acquisition Cloud

With the rapid development of information technology, the number of data isincreasing explosively in the whole world. It is an urgent problem that how toeffectively manage, transport and service massive data, when the era of massive datawhich we emphasis on "data is to service". The application of spatial information isone of the emerging applications for massive data management. Due to thecharacteristics of heterogeneous, multi-source, unstructured, and multi-space-time,etc., storage, transmission, service and other issues of Spatial data become moreprominent.Base on G/S mode and spatial information service cloud system structure, thisissue around "data-centric and with the main clue of identifier" of thought Due to thissystem structure, have a schema based on space information service cloud architectureof more sensor data acquisition and registered system which from analysis thefeatures of data to research the thought of meta-data management. Fast perception anddynamic management of massive data has become fact.Meanwhile, with the theories and technologies of the data registration center andthe geographical information browser, this paper has designed a prototype verificationsystem of sensor data acquisition based on location information according to thearchitecture of multi-sensor data acquisition and registration system. Through theacquisition, transmission, management and service of temperature data, prototypeverification system could be used in the verification of the theory and principle ofacquisition and management of physical world data in spatial information service cloud.Finally, implement the display of real-time temperature data in geographical information browser, which is used in emergency management and disease monitoring.After did the above work, I have done a deeply research for some principle for thecollected physical data, spatial information cloud services architecture, acquisitionand exchange for physical data. Based on these research, it formed a set of theoreticaland method for acquisition and management of the physical world data.Through the work mentioned above, the authors made more in-depth study incollecting data on the physical, architecture of the spatial information services cloudand physical collection and exchange of relevant principles, and this article made thefollowing findings:(1) A system that used for verifying the system of data gathering and registeringfrom multi-sensor.As the reason of the multi-sensor data gathering and transforming system framethat based on the G/S mode may be massive and complicated, it can’t be absolutelycompleted in a short time. So, in the paper, I emphatically designed and realized asystem that used for verifying the system of data gathering and registering from multi-sensor.With this system, the principles and technologies can be tested in this paper.(2) Designed a structure of multi markup language MSML (Multi-Sensor MarkupLanguage).According to the physical acquisition system based on actual needs, this paperhas designed a set of multiple sensor markup language MSML grammatical structureand provided a unified description method of physical data acquisition.This set ofMSML grammar structure can realize the physical data registration, exchange,distribution and sharing, which provides technical support for acquisition of cloudphysics based on G/S model.At the same time, after the previously mentioned study, this article also made thefollowing innovation:(1) Proposed a architecture for spatial information service based on cloud sensordata collection and registration system architecture.Based on the research of data exchange standard both at home and abroad,combine with the features of data and emerging industry application of physical worlddata, this article proposed a system schema of multi-sensor data acquisition andregistered which based on the framework of spatial information service cloud. Thissystem schema has four layers: collection layer, transmission layer, exchange layerand interface layer. And these layers can make physical world data collected,transmitted, exchanged and shared efficiently. (2) Proposed a physical collection of data exchange standards–MSMLIn-depth study by collecting data on physical characteristics and classification,combined with the data exchange standard HGML（Hyper Geographic MarkupLanguage）/XXML（XX Markup Language） research which based on the G/S mode,this paper presents a data exchange standards for physical collection which calledMulti-Sensor Markup Language（MSML）.This markup language is supporting for aunified description of the physical collection data.
