There are three types of observed data produced by the 13.7-meter millimeter-wave radio telescope. The first type is observed in the single-point observation mode according to the requirements of the observer. Each spectral line contains one Fits file, and one record in the database table corresponds to the header information of one file.A total of 3.06 million spectral lines have been observed since 2003.The second method is to use OTF observation mode to observe data as required by the observer. and two fits cube files are generated after averaging the scan results of the same area mapped every day, with one record in the database corresponding to the header information of that two file. The scan area ranges from 10′ × 10′ to 30′ × 30′, and more than 5,900 areas have been observed since 2011.The third is Milky Way Imaging Scroll Painting (MWISP), The Purple Mountain Observatory (PMO) of the Chinese Academy of Sciences has organized MWISP project since November 2011. The 13.7m millimeter wave telescope of the Qinghai Station of PMO has been used to simultaneously observe the three molecular spectral lines of CO(J=1-0) and its isotopes 13CO/C18O(J=1-0) near the galactic plane of the North sky. The first phase of the survey, which has lasted for 10 years, has been completed at the end of April 2021, covering a total of 2,400 square degrees 0°≤ l≤ 240°,|b|≤ 5°, and establishing the Millimeter Wave Radio Astronomy Database. After the discussion of the MWISP survey working group, it was decided to continue the second phase of the MWISP survey and extend the survey area to |b|<10°. This survey will help to expand scientific objectives and provide a wider range of molecular gas distribution data for multi-band astronomical research. The second phase of the survey has begun on September 1, 2021 and is expected to last the next ten years.
