specific Embodiment approach 1
[0020] Specific implementation mode one: see figure 1 , 2 and 4 illustrate the present embodiment, the portable vehicle speed sensor pulse simple detector described in the present embodiment, it comprises power processing circuit 1, comparator 2, counter 3, decoder 4, display 5, casing 6, rotating shaft 7 and limit devices;
[0021] The power processing circuit 1 is respectively used to provide working power signals to the comparator 2, the counter 3, the decoder 4 and the display 5,
[0022] The data signal input end of comparator 2 is used to receive the pulse signal that the pulse sensor to be measured sends, and the data signal output end of comparator 2 is connected with the counting pulse signal input end of counter 3, and the counting result output end of described counter 3 is connected with The decoding signal input end of decoder 4 is connected, and the decoding signal output end of decoder 4 is connected with the display signal input end of display 5;

specific Embodiment approach 2
[0029] Specific embodiment two: the difference between this embodiment and the portable speed sensor pulse detector described in specific embodiment one is that the limiting device is composed of a positioning screw 9 and a limiting rod 11, and the positioning screw 9 is connected to the rotating The shaft 7 is arranged in parallel and fixed on the inner side of the rear side wall of the housing 6. The stop rod 11 is vertically fixed on the side wall of the rotation shaft 7, and the distance between the set screw 9 and the side wall adjacent to the rotation shaft 7 is less than the limit The length of the rod 11 , and the distance between the limit rod 11 and the rear side wall of the housing 6 is smaller than the distance between the nut of the set screw 9 and the rear side wall of the housing 6 .
[0030] The limiting device described in this embodiment can limit the rotation of the rotating shaft 7 within a range of 360 degrees, and then only measure the pulse data generated...
specific Embodiment approach 3
[0031] Specific implementation mode three: see figure 1 and 2 This embodiment is described. The difference between this embodiment and the simple portable vehicle speed sensor pulse detector described in Embodiment 1 or Embodiment 2 is that the power processing circuit 1 is realized by a chip of model AE2576T-5.0.
