Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] The specific embodiments of the utility model will be described in detail below in conjunction with the drawings.

[0026] Figure 1is a front view of the weather station device for the unmanned aerial vehicle nest according to the embodiment of the utility model.

[0027] As Figure 1 Indicated, the weather station device for the unmanned aerial vehicle nest includes: anemometer 1, shell 2, camera 3 and indicating lamp 4.

[0028] Among them, anemometer 1 is installed above shell 2;Shell 2 is provided with a groove, and the camera 3 is installed in the groove, and the indicating lamp 4 is also arranged on the shell.The weather station device for the unmanned aerial vehicle nest also includes a base 5, which is installed below the shell 2.The base is provided with a plurality of grooves around the outer periphery of the base.

[0029] Furthermore, the weather station device for the unmanned aerial vehicle nest also includes a circuit unit.The circuit unit includes a temperature sensor circuit, a humidity sensor circuit and a processor, which are arranged in the shell, the temperature sensor circuit is connected with the processor, the temperature sensor circuit is connected with the processor, the processor is connected with the camera 3, the processor is connected with the anemometer 1, and the processor is connected with the indicating lamp 4.

[0030] Among them, the temperature sensor circuit includes a thermistor, a voltage reference chip and an instrument amplifier, the voltage reference chip is connected to the thermistor, the voltage reference chip and the power supply, the voltage reference chip provides a first voltage for the thermistor and a second voltage for the instrument amplifier, and the instrument amplifier is connected to the thermistor, wherein the instrument amplifier receives the differential signal output by the thermistor and amplifies and outputs the differential signal to the processor.

[0031] In one embodiment, the indicating lamp is used to indicate whether the weather station device is working normally.When the weather station device is powered on, the indicating lamp is always on.The indicating lamp is used to display whether the sensor data is within the predetermined value range, and when the sensor data is abnormal (i.e., the sensor data is not within the predetermined value range), the indicating lamp flashes.

[0032] It should be noted that the camera 3 transmits the acquired image data to the processor, and the processor transmits the image data to the client of the relevant personnel (such as operation and maintenance personnel, etc.) through wireless or wired data transmission mode.

[0033] It should be noted that the anemometer is an instrument for measuring wind speed.Different types of anemometers use different technical principles (such as cup anemometer, electric sensor, etc.), which are suitable for different application requirements.In the utility model, the anemometer 1 is a cup anemometer.

[0034] In one embodiment, the anemometer 1 comprises a transmission shaft 14, three connecting rods 13, three wind cups 11, and a circular cover 12, which is installed above the transmission shaft 14, one end of each of the three connecting rods 13 is fixedly connected to the transmission shaft 14, and the other end of each of the three connecting rods 13 is connected to one of the three wind cups 11, and the mouths of the three wind cups 11 are arranged in the same direction.

[0035] The wind cups 11 are generally made of light materials and can rotate under the action of wind. The rotation speed of the wind cups 11 changes with the wind speed, thereby reflecting the wind speed. The three connecting rods 13 connect the transmission shaft 14 and the wind cups 11, ensuring that the rotation energy of the wind cups 11 under the action of wind can be effectively transmitted to the transmission shaft 14. The circular cover 12 is used to protect the wind cups 11 and other internal mechanical structures, and can also guide the rotation of the wind cups 11, reducing the irregularity of air flow, thereby improving the measurement accuracy of the anemometer 1.

[0036] It should be noted that the mechanical movement of the transmission shaft can be converted into an electrical signal by an encoder and a Hall effect sensor, and the electrical signal can be converted into wind speed data by a processor. The encoder converts mechanical rotation into an electrical signal (usually a digital signal) to measure rotation speed and position. The Hall effect sensor detects changes in the magnetic field using the Hall effect principle. When the magnetic field changes, the sensor outputs a voltage signal. It is usually used to detect the rotation speed or position of a rotating object.

[0039] Figure 3 It is a circuit schematic diagram of the temperature sensor circuit according to the embodiment of the utility model.

[0040] As shown in Figure 3 The temperature sensor circuit comprises a PT100 thermistor, a voltage reference chip, and an instrument amplifier, and further comprises a second capacitor C2, a third capacitor C3, a first resistor R1, a second resistor R2, a third resistor R3, a fourth resistor R4, and a fifth resistor R5.

[0041] The first pin of the voltage reference chip is connected with the positive electrode, and the first pin of the voltage reference chip is also grounded through a second capacitor C2. The third pin of the voltage reference chip is grounded. The second pin of the voltage reference chip is connected with the second pin of the PT100 thermistor through a first resistor R1. The second pin of the voltage reference chip is also connected with the second pin of the instrument amplifier through a second resistor R2. The second pin of the instrument amplifier is also grounded through a third resistor R3. The first pin of the instrument amplifier is connected with the eighth pin of the instrument amplifier through a fourth resistor. The third pin of the instrument amplifier is connected with the first pin of the PT100 thermistor. The fourth pin of the instrument amplifier is grounded. The fifth pin of the instrument amplifier is grounded. The sixth pin of the instrument amplifier is connected with the processor to transmit the amplified temperature data to the processor. The seventh pin of the instrument amplifier is connected with the positive electrode, and the seventh pin of the instrument amplifier is grounded through a third capacitor C3.

[0042] In one embodiment, the model of the voltage reference chip is REF3030. It should be noted that the REF3030 is a high-precision, low-noise, low-drift 3.0V voltage reference chip. The REF3030 is used to provide a high-stability reference voltage output.

[0043] In one embodiment, the model of the instrument amplifier is AD623. It should be noted that the AD623 is a high-precision, low-power instrument amplifier. The AD623 is used for amplifying weak signals, and meets the requirements of high precision, low noise and low distortion. The AD623 is used for amplifying differential signals, and is a core component in many measurement instruments and sensor signal processing.

[0044] Figure 4 It is a circuit schematic diagram of the humidity sensor circuit according to the embodiment of the utility model.

[0045] As shown in Figure 4 , the humidity sensor circuit comprises a first diode Q1, a second diode Q2, a third diode Q3, a humidity sensor RH and an operational amplifier A1.

[0046] The input end of the humidity sensor RH receives a driving signal through a second capacitor C2, the output end of the humidity sensor RH is connected with the inverting input end of the operational amplifier A1, the non-inverting input end of the operational amplifier A1 is grounded, the output end of the operational amplifier A1 is connected with the processor through the first diode Q1, the anode of the first diode Q1 is connected with the output end of the operational amplifier A1, the anode of the first diode Q1 is connected with the inverting input end of the operational amplifier A1 through the second diode Q2, and the cathode of the first diode Q1 is connected with the inverting input end of the operational amplifier A1 through the third diode Q3.

[0047] It should be noted that after the humidity sensor RH receives the driving signal, an electric signal will be output at the output end, which will change according to the humidity change of the environment where the humidity sensor RH is located. The operational amplifier A1 receives the electric signal output by the humidity sensor RH and amplifies and outputs to the processor.

[0048] In one embodiment, the humidity sensor RH is a humidity-sensitive resistor, and the resistance value of the humidity-sensitive resistor changes with the humidity. The humidity-sensitive resistor is usually composed of a hygroscopic material (such as a polymer, an oxide, etc.). When the air humidity changes, the resistance of the humidity-sensitive resistor will change. In general, when the humidity increases, the humidity-sensitive resistor absorbs water, and its resistance decreases; when the humidity decreases, the humidity-sensitive resistor loses water, and its resistance increases.

[0049] In another embodiment, the humidity sensor RH is a humidity-sensitive capacitor, which is composed of a capacitor with two conductive materials and a hygroscopic layer (usually a polymer). When the air humidity changes, the capacitance value of the hygroscopic layer will change. In general, when the humidity of the environment where the humidity-sensitive capacitor is located increases, the hygroscopic layer of the humidity-sensitive capacitor absorbs water, resulting in an increase in its capacitance; when the humidity decreases, the hygroscopic layer of the humidity-sensitive capacitor loses water, and its capacitance value decreases.

[0050] Further, the humidity sensor circuit further comprises a low dropout regulator, and the power supply is connected to the positive power supply interface of the operational amplifier A1 through the low dropout regulator, so as to provide a positive voltage for the operational amplifier A1.

[0051] It should be noted that the low dropout regulator (LDO) is a kind of linear regulator, which can maintain a small voltage difference (i.e. "low dropout") between the input voltage and the output voltage. The low dropout regulator is used as a power management device to stabilize the input voltage to a lower and stable output voltage.

[0052] In the above description of the present specification, unless otherwise explicitly specified and limited, the terms "fixed", "mounted" or "connected" and the like should be understood in a broad sense. For example, as to the term "connected", it can be fixedly connected, or detachably connected, or integrated; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements or the interaction relationship between two elements. Therefore, unless otherwise explicitly limited in the present specification, the above terms can be understood in the specific meaning of the present application by the person skilled in the art according to the specific circumstances.

[0053] According to the above description of the present specification, those skilled in the art can also understand that the terms used such as "upper", "lower" and the like indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings of the present specification, which are only for the purpose of facilitating the description of the scheme of the present utility model and simplifying the description, and are not explicitly or implicitly indicating that the devices or elements involved must have the specific orientation, be constructed and operated in the specific orientation, therefore the above orientation or positional relationship terms cannot be understood or interpreted as a limitation on the scheme of the present utility model.

Therefore, the features defined with "first" or "second" can explicitly or implicitly include at least one of the features. In the description of the present specification, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise explicitly specifically limited.
