Solar activity is one of the main sources of space disturbances, which are primarily responsible for space disaster weather. Solar activity is concerned with 11 years period and has many exhibitions such as the change of sunspot's number and solar radio flux in 10.7cm wavelength. The 1.0-2.0 GHz, 2.6-3.8 GHz, and 5.2-7.6 GHz solar radio spectrometers and 2840 MHz solar radio telescope of National Astronomical Observatory in Huairou Solar Observational Station have got considerable radio flux data since 1999. In order to make further researches on solar action and develop space weather forecast, the real-time observed data should be well utilized. Therefore we designed the data acquisition, antenna control and real-time web-based database system for the 2840 MHz solar radio telescope. The paper introduces the whole design of a PCI-based data acquisition, antenna control and real-time web-based database system for the solar radio observation at HuaiRou in China. The popular PCI controller-PCI9052 is utilized to implement the interface between PCI bus and peripheral devices. PLD chip is applied for the data transferring and antenna control. The device driver of Windows is developed based on Driverworks and Windows DDK. The real-time database is based on MySQL and Apache.
