Abstract

The invention provides a portable vehicle speed sensor pulse simple detector and a detecting method and belongs to the field of vehicle speed sensor detecting. The problem that according to an existing detecting mode that an oscilloscope is used for detecting whether a vehicle speed sensor is in good condition, detecting speed is slow, and the oscilloscope is large in size, so that carrying is not convenient is solved. The vehicle speed sensor to be detected is fixed at a sensor fixing end of a rotating shaft, a signal output end of the vehicle speed sensor to be detected is connected with a data signal input end of a comparer, then by rotating a rotating disc, the vehicle speed sensor to be detected is controlled to rotate by 360 degrees anticlockwise or clockwise, and after processing through the comparer, a counter and a decoder, a displayer displays the number of pulse signals generated by the vehicle speed sensor. The portable vehicle speed sensor pulse simple detector and the detecting method are mainly used in a vehicle main machine plant for judging the performance of the vehicle speed sensor.

Description

technical field [0001] The invention belongs to the field of vehicle speed sensor detection. Background technique [0002] The traditional detection method for vehicle speed sensor detection is to use oscilloscope oscilloscope and other measurement methods to judge whether the equipment that generates the square wave is intact. This detection method is to process the waveform signal detected by the oscilloscope to obtain the detection result. , the detection speed is slow, and the oscilloscope is bulky and inconvenient to carry, so it is the need of social development to provide a detection device that is easy to carry and has a slow detection speed. Contents of the invention [0003] The present invention aims to solve the problem that the existing method of using an oscilloscope to detect whether the vehicle speed sensor is intact is slow in detection speed, and the oscilloscope is large in size, which makes it inconvenient to carry. The present invention provides a simp...
