Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of sensors, in particular to an anti-freezing modular wind sensor. BACKGROUND
[0002] The modular wind sensor comprises a wind speed sensor and a wind direction sensor.
[0003] The wind speed sensor is a device that converts the speed of air flow into a measurable, transmittable electrical or digital signal. Its function is to measure wind speed.
[0004] The measurement principle of the wind cup type wind speed sensor is that the wind cup is pushed to rotate by the wind, thereby driving the wind cup shaft to rotate. The bottom of the wind cup shaft is provided with an annular magnet, and a Hall effect sensor is installed near the magnet. The Hall effect sensor detects the change of the magnetic field and transmits the signal to a signal processing board. After signal processing, the signal is output through a signal output device.
[0005] Since the wind cup type wind speed sensor needs to rely on mechanical parts to rotate for measurement, in cold winter, if the mechanical parts freeze, it may cause the mechanical parts to be unable to rotate or the rotation resistance to increase, resulting in failure to measure wind speed or large wind speed measurement error.
[0006] In existing products, in order to realize wind cup heating, a double-layer wind cup structure is usually adopted. The double-layer wind cup structure needs to be installed after the production is completed. This design method leads to complicated production of the wind cup.
[0007] The double-layer wind cup structure is more complex, the cost and weight are increased, and the double-layer design needs more parts, more complex molds and assembly processes. The double-layer wind cup has a more complex structure, and its reliability is far inferior to that of the single-layer wind cup in severe weather environment. The double-layer wind cup structure is more complex and heavier, and its starting wind speed is slightly higher than that of the single-layer design. Its response sensitivity is inferior to that of the lightweight single-layer wind cup at very low wind speed. The double-layer wind cup involves complex interaction of two layers of wind cups, and its calibration curve is more nonlinear. It is extremely sensitive to manufacturing precision, and slight size and angle deviation may cause changes in calibration characteristics, increasing production cost and technical threshold.
[0008] The wind direction sensor is a device that uses the physical pointing characteristics of the wind vane structure, cooperates with an angle detection device, and converts the direction of the wind into a measurable electrical signal. Its function is to measure the wind direction.
[0009] The measurement principle of the wind direction sensor is that the wind vane is pushed to rotate by the wind, the wind vane drives the wind vane shaft to rotate, and the bottom of the wind vane shaft is provided with a magnet. The magnetic declination sensor detects the angle change of the magnet and transmits the signal to a signal processing board. After signal processing, the signal is output through a signal output device.
[0010] Since the wind direction sensor needs to rely on the rotation of mechanical components such as wind vane to measure, in cold winter, once the mechanical components freeze, it may cause the mechanical components to be unable to rotate or the rotation resistance to increase, resulting in the wind direction measurement being unable to be performed or the wind direction measurement error being large.
[0011] The current wind direction sensor can only heat the local area of the rotating component, and cannot heat the wind vane pointer, which still causes measurement error or even cannot measure when the wind vane pointer freezes. SUMMARY
[0012] In view of the defects in the prior art, the application provides an anti-freezing modular wind measurement sensor, which can heat the rotating mechanical components to avoid the wind speed and wind direction measurement error or the wind speed and wind direction measurement being unable to be performed caused by the freezing of the mechanical components.

Detailed Implementation
[0042] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.
[0043] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by those skilled in the art to which this invention pertains.
[0044] Example 1
[0045] like Figures 1-8 As shown, this embodiment provides an anti-freezing modular wind sensor, including a base on which a wind speed sensor and a wind direction sensor are mounted;
[0046] The wind speed sensor includes a housing 1 and a wind cup turntable 5. A wind cup turntable shaft 7 is rotatably mounted inside the housing 1. The wind cup turntable 5 is connected to the wind cup turntable shaft 7. The wind cup turntable 5 is composed of an upper layer and a lower layer, with a turntable heating film 11 sandwiched between the upper and lower layers. An arc-shaped arm 12 is connected to the wind cup turntable 5, and a wind cup heating element 13 is embedded within the arc-shaped arm 12. The wind cup 6 is connected to the arc-shaped arm 12, and the wind cup heating element 13 is in contact with the wind cup 6.
[0047] The wind cup turntable 5 is equipped with a wireless heating receiver control board 10 and a turntable temperature sensor 14. The turntable temperature sensor 14, the turntable heating film 11, and the wind cup heating element 13 are all electrically connected to the wireless heating receiver control board 10.
[0048] It also includes a wireless power transmission component. A temperature sensor 15 is provided inside the housing 1. The temperature sensor 15 can detect the temperature information inside the housing 1 and transmit the information to the wireless power transmission component. The wireless power transmission component can transmit power to the wireless heating receiver control board 10.
[0049] The wind direction sensor includes a housing 101 and a wind vane turntable 105. A wind vane turntable shaft 107 is disposed within the housing 101. The wind vane turntable 105 is connected to the shaft 107. A wind vane 106 and a wind vane pointer 112 are connected to the wind vane turntable 105. Both the wind vane turntable 105 and the wind vane pointer 112 are composed of upper and lower layers. A heating film 111 is sandwiched between the upper and lower layers of both the wind vane turntable 105 and the wind vane pointer 112. The wind vane 106 has a space within which a wind vane heating element 113 is disposed.
[0050] The wind vane turntable 105 is equipped with a wireless heating receiver control board 110 and a turntable temperature sensor 114. The turntable temperature sensor 114, the heating film 111, and the wind vane heating element 113 are all electrically connected to the wireless heating receiver control board 110.
[0051] It also includes a wireless power transmission component 1, and a temperature sensor 115 is installed inside the housing 101. The temperature sensor 115 can detect the temperature information inside the housing 101 and transmit the information to the wireless power transmission component 1. The wireless power transmission component 1 can transmit power to the wireless heating receiver control board 110.
[0052] In this embodiment, a temperature sensor 15 is installed inside the outer casing 1. The temperature sensor 15 detects the temperature inside the outer casing 1 and transmits the signal to the wireless power transmission component. For example, when the temperature is detected to be below 10 degrees, the wireless power transmission component transmits power to the wireless heating receiver control board 10. The wireless heating receiver control board 10 controls the rotating heating film 11 and the wind cup heating element 13 to heat. The rotating heating film 11 heats the wind cup rotating disk 5, and the wind cup heating element 13 heats the wind cup 6, thereby avoiding measurement errors or inability to measure caused by the wind cup rotating disk 5 and the wind cup 6 freezing in low-temperature weather.
[0053] By setting a turntable temperature sensor 14, the real-time temperature of the wind cup turntable 5 is detected. For example, if the temperature of the wind cup turntable 5 is detected to be greater than 60 degrees, the turntable heating film 11 and the wind cup heating element 13 are controlled to stop heating, thereby reducing power consumption.
[0054] In this embodiment, the wind cup heating element 13 is set on the arc-shaped arm 12 to heat the wind cup 6. In this way, the wind cup 6 only needs to be set as a single-layer structure. The single-layer wind cup structure is simple, the cost and weight are reduced, the number of parts used is reduced, and the structure and assembly process of the mold are simplified.
[0055] The single-layer structure is simple and has higher response sensitivity. The single-layer wind cup structure can reduce production costs and technical barriers.
[0056] In this embodiment, a temperature sensor 115 is provided on the outer casing 101. The temperature sensor 115 can detect the external temperature and send the signal to the wireless power transmission component 1. For example, when the temperature is detected to be below 10 degrees, the wireless power transmission component 1 transmits power to the wireless heating receiver control board 110. The wireless heating receiver control board 110 controls the heating film 111 and the wind vane heating element 113 to heat. The heating film 111 heats the wind vane turntable 105 and the wind vane pointer 112 at the same time, and the wind vane heating element 113 heats the wind vane 106. This avoids measurement errors or inability to measure caused by icing of the wind vane turntable 105, the wind vane 106 and the wind vane pointer 112 in low-temperature weather.
[0057] By setting a turntable temperature sensor 114 to detect the real-time temperature of the wind vane turntable 105, for example, if the temperature of the wind vane turntable 105 is detected to be greater than 60 degrees, the heating film 111 and the wind cup heating element 113 are controlled to stop heating, thereby reducing power consumption.
[0058] In this embodiment, the wind vane 106 is connected to the circumferential wall of the wind vane turntable 105. The wind vane 106 is a certain distance away from the rotating shaft 107 of the wind vane turntable, which makes the lever arm of the wind vane 106 longer and the torque greater, which greatly enhances the wind vane 106's ability to respond to light winds and greatly improves the stability of wind measurement.
[0059] In this embodiment, the upper layer of the wind vane pointer 113 and the upper layer of the wind vane turntable 105 are integrally formed, and the lower layer of the wind vane pointer 113 and the lower layer of the wind vane turntable 105 are integrally formed, which facilitates production.
[0060] The wind vane 106 is composed of two layers, which facilitates the installation of the wind vane heating element 113.
