detailed description

Hereinafter, the present invention will be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the present invention are marked. This invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative specifications used herein interpreted accordingly.

As shown in Figure 1, the anemometer of the present application includes a wind speed sensor, a wind speed analyzer, a power supply unit and a signal transmission unit; wherein, the wind speed sensor is a fiber grating wind speed sensor, which is used to monitor the wind speed and send the monitoring results to the wind speed analysis The wind speed analyzer is used to receive the monitoring results of the wind speed sensor, analyze the wind speed according to the monitoring results, and then send the analyzed wind speed results to the receiving terminal through the signal transmission unit; the power supply unit includes solar panels and wind power generators; wind power generation The machine is connected with the rotor of the wind cup of the wind speed sensor, and the power supply unit is used to provide the energy required for the work of the wind speed sensor.

The principle of the fiber grating wind speed sensor to measure the wind speed is: the wind in the wind field generates a torque to the wind cup, which drives the runner to rotate. The greater the wind speed, the faster the speed of the runner. The rotating wheel and the speed cam are fixed together, and the rotation of the rotating wheel drives the speed cam to rotate. Every time the speed cam rotates once, the protruding part of the speed cam will hit the equal-strength cantilever beam to cause a change in deflection, which will cause FBG to stick to the surface of the equal-strength cantilever beam The central wavelength is shifted, and the wavelength change is transmitted by the optical fiber. Counting is performed according to the number of FBG central wavelength changes. The rotational speed is proportional to the wind speed, and the wind speed in the wind field can be obtained.

The power supply unit also includes a wind-solar complementary controller and a battery; the solar panel and the wind generator are connected to the battery through the wind-solar hybrid controller. The working process of the wind power generation system is that when the wind reaches and stabilizes at a certain wind speed, the wind generator continuously converts the wind energy into AC power. In the case of sufficient sunlight, photovoltaic solar panels convert solar energy directly into electrical energy in the form of DC. The electrical energy converted from wind energy and light energy is charged to the storage battery at the same time under the cooperation of the controller. The storage battery plays the role of storing and regulating electric energy, and maintains a constant electric quantity when the environment changes.

Preferably, the rotor of the wind cup of the wind speed sensor of the present application will be directly connected to the low-speed gear of the wind power generator, by driving the high-speed gear meshed with the low-speed gear, and driving the generator shaft connected with the high-speed gear, driving Generators generate electricity.

The signal transmission unit of the present application is a wireless signal transmission unit based on GPRS wireless transmission technology. The use of wireless transmission avoids the laying of transmission signal lines, which not only simplifies the line structure, but also saves costs.
