Description
Technical field
The present invention relates to astronomical observation field, especially a kind of astronomical telescope image remote monitoring system and method.
Background technique
With astronomical telescope design and the continuous improvement of manufacturing technology and the rapid development of information technology, ephemeris information
Show the trend of explosive growth.Although announced chronometer data is freely shared in global range, due to seeing
Often all there is certain hysteresis quality in the publication of measured data, and astronomical observation website is usually located at high altitude localities, personnel's value
It is larger to keep difficulty, it is even unattended, thus current demand is proposed to the acquisition and monitoring of telescope real time data.
The existing astronomical observation station usually captures observed image using telescope camera when obtaining observation data
Afterwards, the generation of postpositive disposal computer is transferred to meet common data format FITS (the Flexible Image of astronomical community
Transport System) file, researcher studied after obtaining Fits image file and to a certain range crowd into
Row is issued and is shared.However, researcher usually requires to monitor observation data in time in observation site, for not observing
The researcher at scene is commonly present the lag of long period when obtaining observation data, this be possible to cause researcher because
Time lag loses the first chance of great discovery.Further, since Fits image file is often larger, it is limited in communication network bandwidth
Under the conditions of, it is also difficult to it realizes the real-time of FITS image file or quasi real time issues.
Summary of the invention
Goal of the invention of the invention is: being directed to above-mentioned problems of the prior art, provides a kind of astronomical telescope
