[0002] Intelligent measurement is a process of accurately measuring and analyzing physical quantities by means of advanced sensor technology, data acquisition equipment, and intelligent algorithms. It has become a key technology for achieving efficient and accurate monitoring and decision-making in multiple fields. Its application scenarios include industrial manufacturing, healthcare, environmental protection, and construction engineering. In environmental protection, it monitors environmental indicators such as air pollution, water quality, and soil quality to support the formulation of effective environmental protection policies and measures. For example, intelligent sensors can continuously monitor the concentration of PM2.5 or other common air pollutants in the air, the heavy metal content in water quality, etc., and upload the data to the environmental protection department.

[0003] An intelligent measurement device is an instrument that combines advanced sensor technology, data processing algorithms, communication technology, and automation control technology to achieve accurate measurement, real-time monitoring, data analysis, and intelligent decision-making of physical quantities (such as temperature, pressure, displacement, flow rate, force, electrical parameters, etc.). Through an integrated design, it combines the functions of traditional measuring instruments with intelligent technology and is widely used in industrial production, energy management, environmental monitoring, healthcare, agriculture, transportation, and other fields.

[0004] Publication No. "CN101893645A" discloses an ultrasonic wind speed and direction measurement device in the technical field of wind speed and direction measurement, which includes a wind-sensitive rod, a base, an ultrasonic transmitter, and at least three ultrasonic receivers. The wind-sensitive rod is a vertical cantilever structure. The ultrasonic transmitter is fixedly arranged at the suspended end of the wind-sensitive rod. The ultrasonic receivers are fixedly arranged in an equilateral triangle on the base. The base is horizontally arranged under the wind-sensitive rod. The projection of the fixed end of the wind-sensitive rod on the base overlaps with the center of the equilateral triangle formed by the three ultrasonic receivers. The present invention uses only one ultrasonic transmitter and three receivers to achieve the purpose of measuring both wind speed and direction. Compared with the prior art, it not only has a simple structure, but also because of the use of the wind-sensitive rod, the distance from the ultrasonic transmitter to the ultrasonic receiver will change under the action of wind, thereby greatly reducing the volume and improving the measurement sensitivity.

[0005] The above-mentioned patent achieves the purpose of measuring both wind speed and wind direction with an ultrasonic transmitter and three receivers. Compared with the prior art, it not only has a simple structure, but also, due to the use of a wind-sensitive rod, the distance between the ultrasonic transmitter and the ultrasonic receiver will change under the influence of wind, thereby greatly reducing the volume and improving the measurement sensitivity. However, in the existing intelligent measurement devices manufactured using the ultrasonic principle, during the measurement of wind speed and wind direction, it is impossible to correct and compensate for the deflection disturbance of the wind direction, resulting in a large ultrasonic measurement error, increasing the difficulty of collecting wind speed and wind direction data in a small area, and making it impossible to accurately monitor the wind direction and wind speed anomalies in a small area, thus making it impossible to monitor the accumulation of air pollutants in a small area. Moreover, the intelligent measurement devices manufactured using the ultrasonic principle cannot measure the concentration of PM2.5 or other common air pollutants.

[0018] As a preferred embodiment of the present invention, a wind direction block is fixedly connected to the top of the conical wind cover.

[0019] An intelligent measurement method includes the following steps:

[0020] S1. Positioning and installation:

[0021] Hold the plug rod by hand and insert the entire intelligent measurement device into the soil with the shell more than 1 meter above the ground. At the same time, hold the plug rod with one hand and the shell with the other hand, and rotate the shell to drive the rotating sleeve to rotate, so that the plurality of elastic rubber outer convex teeth rotate between the plurality of inner convex teeth, making the protruding end of the shell point to the due south direction, that is, the notch of the graduated copper strip is aligned with the due south direction. Then, the entire intelligent measurement device is externally powered to complete the positioning and installation of the intelligent measurement device.

[0022] S2. Wind direction measurement:

[0023] In windy weather, the drive motor is powered off and stops. At the same time, the output end of the electric push rod contracts to pull the ratchet pawl away from the ratchet wheel, releasing the locking of the rotation of the conical wind cover. The wind blows the conical wind cover and the wind direction block. The wind blowing from the side of the conical wind cover pushes the conical wind cover to deflect, making the small head end of the conical wind cover face the oncoming wind direction. At the same time, during the deflection process of the conical wind cover, the wind direction block gradually reduces the deflection swing amplitude of the conical wind cover by aligning with the oncoming wind direction, making the small head end of the conical wind cover accurately track the wind direction. The deflection of the conical wind cover drives the turntable, insulating sheet, and graduated copper strip to deflect, thereby changing the fitting position between the graduated copper strip and the spherical electric contact, changing the length of the micro-current conductor passing through the graduated copper strip, and then changing the current resistance value flowing in series to the integrated terminal. With the input micro-current voltage unchanged, the current is calculated using the Ohm's formula stored in the integrated terminal. According to the current value, the wind direction corresponding to the current in the database is matched to achieve the wind direction measurement of the intelligent measurement device.

[0024] S3. Disturbance Compensation:

[0025] During the wind direction measurement, when the conical wind hood deflects and swings, the integrated terminal collects the current value changes generated during the swinging process of the conical wind hood at a measurement frequency of once every 0.02 seconds, statistically analyzes the change frequency of the wind direction, calculates the median of the current values, calculates the compensation difference between the median of the current values and the single measurement current value within 1 second before the conical wind hood deflects and swings, establishes a temporary wind direction compensation database through a large number of compensation differences, compensates and adjusts the wind direction current pointed by the conical wind hood, and then realizes the disturbance compensation of the measured wind direction by the intelligent measurement device;

[0026] S4. Wind Speed Measurement:

[0027] When the small head end of the conical wind hood is aligned with the wind direction, the electric push rod is powered on and started. The output end of the electric push rod pushes the pawl to engage with the ratchet, locking the deflection and swing of the conical wind hood. Air flows between the inner walls of the conical wind hood. The transmitting end of the ultrasonic component emits high-frequency infrasound waves to the receiving end of the ultrasonic component at an interval of once every 0.02 seconds. The high-frequency infrasound waves are affected by the flowing air. By using the receiving time difference of the high-frequency infrasound waves, the air flow velocity is calculated, and then the wind speed is calculated to realize the wind speed measurement of the intelligent measurement device;

[0028] S5. Concentration Measurement:

[0029] During the wind speed measurement, the integrated terminal stores an infrasound wave receiving time difference database under different concentrations and wind speeds, so that a reference database of wind speed and the corresponding PM2.5 or other common air pollutant concentrations when the infrasound wave is received is established in the storage unit of the integrated terminal. The infrasound wave receiving time difference generated during the wind speed measurement is compared with the reference database. First, the corresponding PM2.5 or other common air pollutant concentration value range is found by using the infrasound wave receiving time difference, and then the correct PM2.5 or other common air pollutant concentration value is selected through the wind speed, realizing the measurement of PM2.5 or other common air pollutant concentrations;

[0030] S6. Reset and Calibration:

[0031] After the wind direction measurement, wind speed measurement and concentration measurement, the drive motor is powered on and started. The output end of the drive motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate through meshing with the driven gear, so that the driven gear drives the hollow rotating column to rotate. Then the hollow rotating column drives the turntable and the conical wind hood to deflect. The turntable drives the scale copper strip to deflect, so that the spherical electric contact is located between the notches of the scale copper strip, realizing the reset and calibration of the small head end of the conical wind hood.

[0032] Compared with the prior art, the beneficial effects of the present invention are:

[0033] 1. In this solution, during the micro-current cycle, an integrated terminal, a rotating connection wire, a fixed connection wire, a graduated copper bar, and a spherical electrical contact form a micro-current cycle. The storage unit of the integrated terminal stores a statistical program and a database. The integrated terminal measures at a frequency of once every 0.02 seconds, collects the change in current values generated during the swinging process of the conical wind hood, statistically calculates the change frequency of the wind direction, calculates the median of the current values, calculates the compensation difference between the median of the current values and the single measurement current value within 1 second before the conical wind hood deflects and swings, establishes a temporary wind direction compensation database through a large number of compensation differences, compensates for the increase and decrease of the wind direction current pointed by the conical wind hood, and then realizes the disturbance compensation of the measured wind direction by the intelligent measurement device. The mechanical structure is used to correct and compensate for the deflection disturbance of the wind direction of the ultrasonic wind speed and wind direction measurement device, realizing the accurate acquisition of wind speed and wind direction data in a small area, and achieving the monitoring of the aggregation of air pollutants in a small area.

[0034] 2. In this solution, the input voltage is constant during the cycle, while the current resistance value changes. The current is calculated through Ohm's formula. According to the current value, the corresponding wind direction in the database is matched. The retaining sleeve is used to lift the spherical electrical contact, and the spring is used to squeeze and lift the retaining sleeve. When measuring the wind direction, a micro-current cycle is formed among the integrated terminal, the rotating connection wire, the fixed connection wire, the graduated copper bar, and the spherical electrical contact. The conical wind hood rotates the graduated copper bar, making the spherical electrical contact at different fitting points with the graduated copper bar, gradually changing the length of the graduated copper bar through which the micro-current flows, and then changing the current resistance value during the micro-current cycle. With the input voltage constant and the current resistance value changing, the current is calculated through Ohm's formula. According to the current value, the corresponding wind direction is matched. The spherical electrical contact contacts different scale bar contacts on the graduated copper bar to measure different wind directions, realizing the accurate measurement of the wind direction by the intelligent measurement device.

[0035] 3. In this solution, during the deflection and swing of the conical wind shield, the driving motor is powered off and stops. The conical wind shield is blown by the crosswind, causing the conical wind shield to drive the hollow rotating column to deflect. The hollow rotating column drives the driven gear to rotate. The driven gear drives the driving gear to rotate through meshing with the driving gear. The driving gear drives the rotor in the driving motor to rotate, forming negligible power. At the same time, after wind direction measurement, wind speed measurement, and concentration measurement, the driving motor is powered on and starts. The output end of the driving motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate through meshing with the driven gear, causing the driven gear to drive the hollow rotating column to rotate. Then, the hollow rotating column drives the turntable and the conical wind shield to deflect. The turntable drives the scale copper strip to deflect, making the spherical electric contact located between the notches of the scale copper strip, realizing the reset and correction of the small head end of the conical wind shield. Then, the driving motor is powered off and stops, achieving the ability to quickly reset the conical wind shield, ensuring the elimination of the interference of the previous wind direction before the next wind measurement, thereby improving the wind direction measurement accuracy of the intelligent measurement device. At the same time, the wind direction block is used to receive the push and guidance of the incoming wind, gradually reducing the deflection and swing amplitude of the conical wind shield, making the small head end of the conical wind shield accurately track the wind direction, and effectively improving the wind direction measurement accuracy of the intelligent measurement device.

[0036] 4. In this solution, during rainy and windy weather, rainwater flows down along the conical outer wall of the sealing cover without flowing into the shell. At the same time, the annular sealing ring fills the gap between the hollow frustum and the sealing cover, preventing the airflow from backflowing rainwater into the shell, thereby preventing rainwater from entering the shell and the hollow cover to damage the electronic components and extending the service life of the intelligent measurement device.

The driving gear 25 is arranged between the inner walls of the housing 1 and is located below the partition plate 2. The driving motor 26 is fixedly connected to the bottom of the housing 1. The output end of the driving motor 26 extends to the inner wall of the housing 1, and the output end of the driving motor 26 is fixedly connected to the driving gear 25.

[0061] In the present invention, the partition plate 2 is used to divide the space inside the housing 1. The hollow rotating column 5 is used to support and fix the conical wind hood 8, the driven gear 24 and the ratchet wheel 27. The driven gear 24 is used to drive the hollow rotating column 5 to rotate. The driving gear 25 drives the driven gear 24 to rotate through meshing with the driven gear 24. At the same time, the driven gear 24 can also drive the driving gear 25 to rotate through meshing with the driving gear 25. The driving motor 26 is used to drive the driving gear 25 to rotate.

[0070] A rotating sleeve 20 is fixedly connected to the bottom of the hollow cover 15. A plug rod 21 is fixedly connected between the inner walls of the rotating sleeve 20.

[0071] In the present invention, the rotating sleeve 20 is used to accommodate the plug rod 21 and the plurality of elastic rubber outer convex teeth 23. The plug rod 21 is used to support and fix the plurality of elastic rubber outer convex teeth 23. The plurality of inner convex teeth 22 are used to engage with the plurality of elastic rubber outer convex teeth 23. The plurality of elastic rubber outer convex teeth 23 elastically clamp the plug rod 21 by engaging with the plurality of inner convex teeth 22. When installing the intelligent measuring device, by rotating the housing 1, the protruding end of the housing 1 is oriented towards the due south direction, which is convenient for positioning and installing the whole intelligent measuring device.

[0072] A wind direction block 31 is fixedly connected to the top of the conical wind hood 8.

[0073] In the present invention, the wind direction block 31 is used to receive the push and guidance of the incoming wind, gradually reduce the deflection and swing amplitude of the conical wind hood 8, so that the small head end of the conical wind hood 8 accurately tracks the wind direction, and effectively improves the wind direction measurement accuracy of the intelligent measuring device.

[0074] An intelligent measurement method includes the following steps:

[0075] S1. Positioning and installation:

[0076] Hold the insertion rod 21 by hand and insert the whole intelligent measuring device into the soil. The housing 1 should be more than 1 meter above the ground. At the same time, hold the insertion rod 21 with one hand and the housing 1 with the other hand, and rotate the housing 1 to drive the rotating sleeve 20 to rotate, so that the multiple elastic rubber outer convex teeth 23 rotate between the multiple inner convex teeth 22, making the convex end of the housing 1 point to the due south direction, that is, the notch of the scale copper strip 32 is aligned with the due south direction. Then, connect the whole intelligent measuring device to an external power supply to complete the positioning and installation of the intelligent measuring device.

[0077] S2. Wind direction measurement:

[0078] In strong wind weather, the driving motor 26 is powered off and stops running. At the same time, the output end of the electric push rod 29 contracts to pull the pawl 28 away from the ratchet 27, releasing the locking of the rotation of the conical wind cover 8. The wind blows the conical wind cover 8 and the wind direction block 31. The wind blowing from the side of the conical wind cover 8 pushes the conical wind cover 8 to deflect, making the small head end of the conical wind cover 8 point to the oncoming wind direction. At the same time, during the deflection process of the conical wind cover 8, the wind direction block 31 gradually reduces the deflection swing amplitude of the conical wind cover 8 by aligning with the oncoming wind direction, so that the small head end of the conical wind cover 8 accurately tracks the wind direction. The deflection of the conical wind cover 8 drives the turntable 13, the insulating sheet 14 and the scale copper strip 32 to deflect, thereby changing the fitting position between the scale copper strip 32 and the spherical electric contact 16, changing the length of the micro-current conductor passing through the scale copper strip 32, and then changing the current resistance value flowing in series to the integrated terminal 9. Under the condition that the input micro-current voltage remains unchanged, use the Ohm's formula stored in the integrated terminal 9 to calculate the current, and match the wind direction corresponding to the current in the database according to the current value to achieve the wind direction measurement of the intelligent measuring device.

[0079] S3. Disturbance compensation:

[0080] During the wind direction measurement process, during the deflection swing of the conical wind cover 8, the integrated terminal 9 collects the current value changes generated during the swing of the conical wind cover 8 at a measurement frequency of once every 0.02 seconds, counts the change frequency of the wind direction, calculates the median of the current values, calculates the compensation difference between the median of the current values and the single measurement current value within 1 second before the deflection swing of the conical wind cover 8, and establishes a temporary wind direction compensation database through a large number of compensation differences to compensate and increase or decrease the wind direction current pointed by the conical wind cover 8, thereby realizing the disturbance compensation of the measured wind direction by the intelligent measuring device.

[0081] S4. Wind speed measurement:

[0082] When the small end of the conical wind cover 8 is aligned with the wind direction, the electric push rod 29 is energized to start. The output end of the electric push rod 29 pushes the pawl 28 to engage with the ratchet wheel 27, locking the deflection swing of the conical wind cover 8. Air flows between the inner walls of the conical wind cover 8. The transmitting end of the ultrasonic component 30 emits high-frequency infrasound waves to the receiving end of the ultrasonic component 30 at an interval of 0.02 seconds each time. Affected by the flowing air, the high-frequency infrasound waves use the receiving time difference of the high-frequency infrasound waves to calculate the air flow velocity, and then calculate the wind speed, realizing the wind speed measurement of the intelligent measuring device;

[0083] S5. Concentration measurement:

[0084] During the wind speed measurement, a database of infrasound wave receiving time differences at different concentrations and wind speeds is stored in the integrated terminal 9, enabling a reference database of wind speed and the corresponding PM2.5 or other common air pollutant concentrations at the time of infrasound wave reception to be established in the storage unit of the integrated terminal 9. The infrasound wave receiving time difference generated during the wind speed measurement is compared with the reference database. Using the infrasound wave receiving time difference, first find the corresponding numerical range of PM2.5 or other common air pollutant concentrations, and then screen out the correct PM2.5 or other common air pollutant concentration values through the wind speed, realizing the measurement of PM2.5 or other common air pollutant concentrations;

[0085] S6. Reset and calibration:

[0086] After the wind direction measurement, wind speed measurement, and concentration measurement, the drive motor 26 is energized to start. The output end of the drive motor 26 drives the active gear 25 to rotate. The active gear 25 drives the driven gear 24 to rotate through meshing with the driven gear 24, enabling the driven gear 24 to drive the hollow rotating column 5 to rotate. Subsequently, the hollow rotating column 5 drives the turntable 13 and the conical wind cover 8 to deflect. The turntable 13 drives the scale copper strip 32 to deflect, making the spherical electric contact 16 located between the notches of the scale copper strip 32, realizing the reset and calibration of the small end of the conical wind cover 8.

Positioning and installation: Hold the insertion rod (21) by hand, insert the whole intelligent measurement device into the soil, and keep the shell (1) more than 1 meter above the ground. At the same time, hold the insertion rod (21) with one hand and the shell (1) with the other hand, and rotate the shell (1) to drive the rotating sleeve (20) to rotate, so that multiple elastic rubber outer convex teeth (23) rotate between multiple inner convex teeth (22), making the convex end of the shell (1) point to the due south direction, that is, the notch of the scale copper strip (32) is aligned with the due south direction. Then, the whole intelligent measurement device is externally powered to complete the positioning and installation of the intelligent measurement device; S2. Wind direction measurement: In strong wind weather, the drive motor (26) is powered off and stops running. At the same time, the output end of the electric push rod (29) retracts to pull the pawl (28) away from the ratchet wheel (27), releasing the locking of the rotation of the conical wind shield (8). The wind blows on the conical wind shield (8) and the wind direction block (31). The wind blowing from the side of the conical wind shield (8) pushes the conical wind shield (8) to deflect, making the small head end of the conical wind shield (8) point to the oncoming wind direction.

The output end of the electric push rod (29) pushes the pawl (28) to engage with the ratchet wheel (27), locking the deflection swing of the conical wind cover (8). Air flows between the inner walls of the conical wind cover (8). The transmitting end of the ultrasonic component (30) emits high-frequency infrasound waves to the receiving end of the ultrasonic component (30) at an interval of 0.02 seconds each time. Affected by the flowing air, the high-frequency infrasound waves are used to receive the time difference, calculate the air flow velocity, and then calculate the wind speed to achieve the wind speed measurement of the intelligent measuring device; S5. Concentration measurement: During the wind speed measurement process, a database of infrasound wave reception time differences at different concentrations and wind speeds is stored in the integrated terminal (9), enabling a reference database of wind speed and the corresponding PM2.5 or other common air pollutant concentrations at the time of infrasound wave reception to be established in the storage unit of the integrated terminal (9). The infrasound wave reception time difference generated during the wind speed measurement is compared with the reference database. First, the corresponding PM2.5 or other common air pollutant concentration value range is found using the infrasound wave reception time difference, and then the correct PM2.5 or other common air pollutant concentration value is selected through the wind speed, achieving the measurement of PM2.5 or other common air pollutant concentrations; S6. Reset and calibration: After the wind direction measurement, wind speed measurement, and concentration measurement, the drive motor (26) is powered on and started. The output end of the drive motor (26) drives the active gear (25) to rotate. The active gear (25) drives the driven gear (24) to rotate through meshing with the driven gear (24), causing the driven gear (24) to drive the hollow rotating column (5) to rotate. Subsequently, the hollow rotating column (5) drives the turntable (13) and the conical wind cover (8) to deflect. The turntable (13) drives the scale copper strip (32) to deflect, enabling the spherical electrical contact (16) to be located between the notches of the scale copper strip (32), achieving the reset and calibration of the small head end of the conical wind cover (8).
