Interval axle counting system

The utility model relates to the technical field of railway signals, in particular to an interval axle counting system. The system comprises an axle counting sensor arranged at an interval axle counting point and used for detecting train wheels, an axle counting host used for processing signals of the axle counting sensor and outputting interval occupation or idle signals, an interval track relayin communication connection with the axle counting host, and an interval zero resetting button in communication connection with the axle counting host. According to the interval axle counting system,interval axle counting is achieved by arranging the amplifying units, the counting units and the main control unit which are in one-to-one correspondence with the axle counting sensors, and independence of an interval axle counting channel and accuracy of interval axle counting are guaranteed; an interval occupation or idle signal is sent to the blocking equipment through the interval track relay,and the interval occupatio
