The Design And Implementation Of The Production Process Supervisory Control System Of Remote Sensing Business Based On RMI

With the rapid development of aerospace technology, the remote sensing of industry has reacheda certain scale in China, and they have deeply influenced our lives deeply.In the field of remote sensing,remote sensing satellite get a certain number of remote sensing images every day, but these images are theoriginal images, we are unable to get meaningful information from these original images, they don’t direct-ly in the service of our production and living.In order to obtain meaningful data from these original images,we need to do a certain algorithm processing for the original image, so as to get to all kinds of informationfor our production and living services, and then we can realize the significance of remote sensing of career.The users can not fell the production process of the remote sensing images in the server, users canonly see production accomplish after processing is completed.Therefore, in accordance with the need ofremote sensing image processing, an effective monitoring system for real-time monitoring of remote sens-ing image processing progress, monitoring production process of remote sensing images, and remote sens-ing image are done to check the production on time.In order to realize the remote sensing image productionprocess real-time monitoring, remote sensing business process monitoring and control system was designedand developed.Remote sensing business process monitoring and control system is the client system of the3~5levels of information product production subsystem, mainly be responsible for the information from thedatabase query, under the control of the scheduling server, from scheduling server task information sum-mary module receives the task information, and then to display the corresponding task information moni-toring interface.By the user in the client’s display interface to realize the real-time monitoring of remotesensing image process.The main results were as follows:1. Design and implement the production process supervisory control system of remote sensing of business.In the full understanding of the analysis on the basis of user requirements, complete the overall architectureof the system requirements analysis and system design. Implements for retrieval of remote sensing imageprocessing production orders, view, download progress monitoring, influence function such as businesssystem. 2. The implementation of communication architecture based on RMI service building. The productionprocess supervisory control system of remote sensing of business is a distributed system, using Java lan-guage as a development language. According to the characteristics of the system and the effectiveness ofdevelopment efforts, the system adopts the RMI technology as the communication mechanism of the sys-tem. Using RMI technology reduce the cost of the system communication function module development,guarantee the system development work quickly and efficiently. And to achieve the object oriented methodto complete the system of communication problems, and ensure safe and reliable communication.3. Implementation is based on multi-thread mechanism and event information processing function of thesystem.A large number of remote sensing images in the process of production will produce large amountsof information production, the production information must be timely and effective transmission and dis-play.The use of multithreading mechanisms and event meet the timeliness and effectiveness of informationprocessing, the production information updated in real time, greatly improving the effectiveness of the sys-tem.
