Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0013] Such as figure 1 As shown, a speedometer includes a detection module 3 , a control circuit 2 , and a display 1 , the control circuit 2 is connected to the display 1 , and the detection module 3 is connected to the control circuit 2 . Place the fan to be tested (not marked in the drawings) horizontally, stick a small iron piece on the blade of the fan, put the detection module 3 above the blade, and push down the sensing side of the detection module 3. In this way, the small iron piece passes the sensing side of the detection module 3 every time the blade rotates. When an iron block passes under the detection module 3, the detection module 3 will send a pulse signal to the single-chip microcomputer circuit 2 through the counting detection channel (not marked in the drawings). When the nu...

Abstract

The invention discloses a velometer comprising a detection module, a control circuit and a displayer. The control circuit is connected with the displayer. The detection module is connected with the control circuit. The beneficial effects of the velometer are that the detection module is quite high in induction frequency, and a single-chip microcomputer circuit adopts the acquired pulse signals so that the velometer is used for substituting certain special velocity measuring equipment to measure rotating speed of fan blades with higher rotating speed, and the measured data are more accurate.

Description

technical field [0001] The invention relates to a speedometer. Background technique [0002] In the prior art, generally when measuring the rotational speed of the fan, the axis of the measuring device is often in contact with the axis of the fan, and the axis of the measuring device rotates together with the axis of the fan. This is very inconvenient to measure, and there is a possibility of losing laps at high speeds. It can no longer meet the current measurement needs. Contents of the invention [0003] To solve the above problems, the present invention provides a speed detector. [0004] The technical means adopted by the present invention to solve technical problems are: [0005] A speedometer, which includes a detection module, a control circuit, and a display, the control circuit is connected to the display, and the detection module is connected to the control circuit. [0006] The above-mentioned speedometer, wherein, the display is an LCD touch screen display....
