Method and device for coincidence event judgment

An embodiment of the invention discloses a method and a device for coincidence event judgment. The method includes prebuilding M memory areas (M=natural number) and acquiring information including occurrence time, position and energy of events more than M to-be-handled events, then sequencing the M to-be-handled events according to the occurrence time to acquire sequenced M to-be-handled events, putting the sequenced M to-be-handled events into the M memory areas sequentially, sequencing the to-be-handled events according to the M memory areas and acquiring the sequenced to-be-handled events until completing execution of all the sequence processes of the to-be-handled events, acquiring the time coincidence events after performing time coincidence judgment on the sequenced to-be-handled events according to the occurrence time, and acquiring the coincidence events after performing space coincidence judgment on the time coincidence events according to the occurrence position. Sequencing efficiency is high so that coincidence event judgment efficiency is improved.
