Title:
AXLE COUNTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/252881
Kind Code:
A1
Abstract:
An axle counting system, comprising: a shaping module (22); a waveform detection module (82); a determining module (83); and an interference signal filtering module (84). The shaping module (22) which is connected to sensing units (111, 112, 121, 122) of wheel sensors (11, 12) is configured to shape sensing signals to generate shaping signals, waveform characteristic data is extracted according to two pulse signals of the shaping signals, and whether a first pulse signal and a second pulse signal satisfy an axle counting signal feature is determined according to the waveform characteristic data to identify an abnormal interference pulse signal. The axle counting accuracy is improved.
