Detailed Description
The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.
Photosensitive reflective patch 5: the fan blade is stuck on the fan blade 6 and is mainly used for reflecting a light source, and the color is silver;
the sensor 1: the light source is fixed on the fan framework 7 through the mounting bracket 2 and mainly used for emitting and collecting light sources, the light sources are emitted to the photosensitive patches and then reflected to the sensor 1, then signals are transmitted to the controller 3, for example, the laser sensor 1 can be sampled, laser is emitted and reflected light is received, and the rotating speed of the fan is calculated by obtaining the reflection frequency of the laser;
the controller 3: mainly receive the sensor 1 signal, count the function, transmit to the data collector 4 after filtering;
data line: the device is mainly used for connecting signals of the controller 3 with the data acquisition unit 4;
and the data acquisition unit 4: the data sent by the controller 3 is collected and recorded, and the collected information can be directly displayed on the device.
On the installing support 2: the sensor fixing device is used for fixing the sensor 1, and is provided with a clamping groove 10 used for being clamped on the fan framework 7, a locking screw hole 11 is formed between the clamping groove 10 and the end face of the mounting support 2, a locking bolt 9 used for locking the fan framework 7 is arranged in the locking screw hole 11, and a mounting hole 8 used for fixing the sensor 1 is formed in the mounting support 2.
The working principle is as follows: fixing a photosensitive reflective patch 5 on the surface of a fan blade 6, fixing one end of a mounting bracket 2 on a fan framework 7, and mounting a sensor 1 at the other end; the angle of the sensor 1 is adjusted to enable the light source to be over against the photosensitive reflective patch 5 (see the principle diagram 1 in detail), the sensor 1 transmits the received reflective signal to the controller 3, the controller 3 performs filtering processing and then transmits data to the data acquisition unit 4, and the data acquisition unit 4 performs data recording and displays the rotating speed of the fan through the display.
The present invention has been described above with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above, and that the invention is not limited to the specific embodiments described above, but rather is intended to cover various insubstantial modifications of the inventive method and solution, or its application to other applications without modification.
