Radio Observatory of Lebedev Physical Institute in Pushchino has one of the most sensitive radio telescope at 110 MHz BSA (Big Scanning Antenna). Since 2012 BSA started multi-beams observations using 96 beams in declination from -8 up to +42 degrees in 6 and 32 frequency bands at 109-112 MHz and time sampling 0.1 s and 0.0125 s. The data stream in 32 bands and time sampling of 0.0125 s is producing 87.5 gigabytes per day. The data obtained can be used for short and long-term monitoring of various classes of radio sources (including radio transients), the Earth's ionosphere, interplanetary and interstellar plasma monitoring. A database is constructed to facilitate access to a large amount of observational data (see http://astro.prao.ru/cgi/out_img.cgi). We discuss algorithms of detection and identification of different classes of transients using the database. In particular we found 83096 events which could be associated with pulsars, scintillation sources and fast radio transients. These events are a homogenous sample suitable for statistical analysis.
