The invention is applicable to an unmanned aerial vehicle flight competition and provides a timing/controlling system for an unmanned aerial vehicle competition. The system comprises at least one response unit, a reading unit and a display unit, wherein each response unit is mounted on the corresponding unmanned aerial vehicle and used for transmitting unique identity code information of the response unit to a reader after receiving a radio-frequency signal transmitted by the reading unit; the reading unit is used for transmitting the radio-frequency signal, performing code identification and time recording after receiving the code information transmitted by the response units, and transmitting identification information and record information to the display unit for display. The system can accurately identify identities of the unmanned aerial vehicles participating in the competition during the unmanned aerial vehicle flight competition as well as measure and display the time at which the unmanned aerial vehicles participating in the competition pass through a measuring point, competitors and audiences can directly know competition conditions conveniently, and furthermore, related data can be provided for an external system, so that flight speeds of the unmanned aerial vehicles participating in the competition can be calculated.
