Example two:
referring to a flowchart of an anemometer calibration method shown in fig. 2, which may be executed by a controller in an anemometer calibration apparatus according to an embodiment, the controller may be an electronic device such as a computer, a processor, or the like, and the method mainly includes steps S201 to S206:
step S201, the stepping motor is rotated to the encoding zero position.
In one specific embodiment, the controller includes, but is not limited to, a PC, and the stepper motor is instructed by the PC software to return to absolute zero (i.e., the encoded zero position). And then the detected anemometer is installed at a 45-degree difference with the horizontal direction. And finally, the system is controlled by one key of a PC (personal computer), so that a fully-automatic label record checking and report generating process is realized. The stepping motor is a stepping motor integrated with codes and can read position signals. The control of the stepping motor is realized by setting a register of the controller. When the PC sends an instruction, the instruction is written into the register, the stepping motor is controlled to rotate to a specified position, a motion instruction is sent, and the stepping motor starts to rotate; the PC then reads the encoder position signal at intervals until the position is within the error range.
And S202, acquiring anemometer parameters and real-time parameters of a wind source, and carrying out zero setting on a static vane of the anemometer based on the anemometer parameters.
In a particular embodiment, the anemometer parameters include: the distance between an anemoscope east and west probe, the distance between an anemoscope north and south probe, the cache depth, the filter sensitivity, the wind speed measurement range and the current loop range. Anemometer parameters are automatically entered into the controller. After the controller is in communication connection with the anemoscope, wind speed and direction data can be provided to the controller in real time. After the controller sends the temperature in the wind tunnel, the anemograph can know the flight degree time of four theoretical east-west south-north axes through calculation. The actual measured time of flight is larger than the theoretical time of flight due to the delay of the hardware circuit, and the part of the time is fixed error time which can be subtracted in the calculation. And then the output wind speed is 0. The controller can finely adjust the fixed error time in the process of setting the static wind indicator to achieve the purpose of ensuring that the output is 0 at the wind speed of 0.
Step S203, rotating the anemometer to a preset direction based on the coding zero position and the static vane zero setting, and rotating from the preset direction to set a plurality of calibration points.
In a specific embodiment, the predetermined direction may include the north direction, and the anemometer may automatically find the north, but requires a greater wind speed to be given. If the wind speed is too low, the airflow in the wind tunnel is unstable, and errors can be introduced. And the wind speed is too high, and errors can be introduced by the vibration of the wind tunnel. Half of the wind speed measurement range is generally taken as the wind speed when finding north.
And step S204, calibrating different wind sources based on the plurality of calibration points and the real-time parameters of the wind sources to respectively obtain a plurality of calibration values.
In one embodiment, the operating software in the controller may hook in advance the wind speed point of the wind source to be calibrated and the angular degree of the calibration point. The more the selected wind speed points and angles are, the higher the fitting accuracy of the anemometer is. But the calibration time is increased accordingly.
And S205, performing linear interpolation on the un-calibrated points according to the plurality of calibrated values to obtain all calibrated values and recording the calibrated values into the anemoscope.
In a specific embodiment, software in the controller records the acquired data of each point at the calibrated wind speed into the anemometer respectively for the anemometer to perform calibration calculation. After the anemoscope measures the measured wind speed and wind direction, a table look-up method is adopted to search the area where the wind speed and the wind direction are located, then the wind speed and the wind direction are calibrated in a linear fitting mode, and the calibrated wind speed and the calibrated wind direction are output to improve the progress.
And S206, rotating the anemoscope again and setting a plurality of detection points, and detecting the anemoscope according to different wind sources, real-time parameters of the wind sources and the plurality of detection points so as to calibrate the anemoscope.
In a specific embodiment, the step of detecting the anemometer is the same as the step of calibrating the anemometer in step S104, and for detection, two sets of data are calculated by the same method and compared, and if the data are the same, the anemometer calibration is proved to be completed. When the wind speed detection method is used for detection, the wind speed points and the angle number which need to be detected can be selected in advance in software. The more the number of angles at the selected wind speed point, the finer the sensor detection, but the longer the detection time.
In the above mode provided by this embodiment, the stepping motor can be rotated to the zero position of the code first, then the fan rotates to provide the wind source of the wind tunnel, then the real-time parameters of the wind source are obtained through the micromanometer and the temperature and humidity sensor, the anemoscope is controlled to rotate through the stepping motor, finally the controller is used for setting the anemoscope to be zero, and then the anemoscope is calibrated, linearly interpolated and detected based on the zero position of the code and the zero setting of the static anemoscope, so as to complete the adjustment of the anemoscope.
In specific implementation, the step of rotating the stepping motor to the zero position of the code comprises the following steps a to c:
