Wherein, the mechanical arm 3 can be replaced according to the type of the humidity switch knob.
The controller 7 is respectively connected with the direct current motor 1, the standard humidity sensor 4 and the to-be-calibrated humidity switch 02 arranged in the humidity simulation chamber 01, the controller 7 is used for acquiring a current humidity value in the humidity simulation chamber 01 transmitted by the standard humidity sensor 4 when detecting that the to-be-calibrated humidity switch 02 is connected and switched between the humidifying component 5 and the dehumidifying component 6, then comparing the current humidity value with a pre-stored preset humidity value, and controlling the rotating speed direction and the rotating angle of the direct current motor 1 by utilizing the positive and negative sum of the difference value of the current humidity value and the preset humidity value, so that the humidity switch knob is adjusted through the mechanical arm 3.
It should be noted that, when the humidity switch 02 to be calibrated is connected and switched between the humidifying part 5 and the dehumidifying part 6, it indicates that the current humidity in the humidity simulation chamber 01 reaches the humidity action value of the humidity switch 02 to be calibrated, that is, the current humidity value transmitted by the standard humidity sensor 4 acquired by the controller 7 at this time is the humidity action value of the humidity switch 02 to be calibrated, so that by comparing the magnitude relationship between the current humidity value and the preset humidity value, it can be determined whether the humidity switch 02 to be calibrated needs to be calibrated.

Referring to fig. 3, an embodiment of the present invention discloses a flowchart of a humidity switch calibration method, where the calibration method is applied to the humidity switch calibration apparatus, and the calibration method includes the steps of:
step S31, when detecting that the humidity switch 02 to be calibrated is connected and switched between the humidifying part 5 and the dehumidifying part 6, acquiring the current humidity value of the humidity simulation chamber 01 transmitted by the standard humidity sensor 4;
step S32, comparing the current humidity value with a pre-stored preset humidity value;
step S33, when the current humidity value is not equal to the preset humidity value, calculating the difference between the current humidity value and the preset humidity value;
it should be noted that, if the current humidity value is equal to the preset humidity value, it indicates that the humidity switch 02 to be calibrated does not need to be calibrated, and at this time, the difference does not need to be obtained.
And step S34, controlling the rotating speed direction and the rotating angle of the direct current motor 1 by using the positive and negative sum of the difference value so as to adjust the humidity switch knob of the humidity switch 02 to be calibrated through the mechanical arm 3.
The specific process of calibrating the humidity switch 02 to be calibrated by the humidity switch calibration device is as follows:
the humidity in the humidity simulation chamber 01 is controlled to gradually increase through the humidifying component 5 (or the humidity in the humidity simulation chamber 01 is controlled to gradually decrease through the dehumidifying component 6), when the humidity in the humidity simulation chamber 01 reaches a humidity action value of the humidity switch 02 to be calibrated, the humidity switch 02 to be calibrated is switched from being connected with the humidifying component 5 to being connected with the dehumidifying component 6 (or the humidity switch 02 to be calibrated is switched from being connected with the dehumidifying component 6 to being connected with the humidifying component 5), the controller 7 obtains a current humidity value transmitted by the standard humidity sensor 4 at the moment, compares the current humidity value with a preset humidity value, and if the current humidity value is the same as the preset humidity value, the humidity switch 02 to be calibrated is not required to be calibrated; if the current humidity value is not equal to the preset humidity value, the positive and negative sum of the difference value between the current humidity value and the preset humidity value is used for controlling the direct current motor 1 to forward or reverse, and the humidity action value of the humidity switch 02 to be calibrated is adjusted to be increased or decreased, so that the automatic calibration of the humidity switch 02 to be calibrated is realized.
In conclusion, it can be seen that the humidity switch calibrating device that this application provided adopts centralized design, all equipment are unified to be controlled by controller 7, for artifical manual calibration, this application can be automatic according to the humidity action value of the humidity switch 02 of waiting to calibrate that acquires, the current humidity value of standard humidity sensor 4 conveying promptly, with the big or small relation of presetting the humidity value, it calibrates to wait to calibrate humidity switch 02, whole calibration process has realized automaticly, thereby the calibration error that produces when having eliminated artifical manual calibration, staff's intensity of labour has been reduced simultaneously, and then calibration efficiency has been improved.
The controller 7 controls the rotation speed direction and the rotation angle of the direct current motor 1 by using the positive and negative sum of the difference value, and the process of calibrating the humidity switch 02 to be calibrated is as follows:
when the difference is a positive value, the humidity action value of the humidity switch 02 to be calibrated is higher than the preset humidity value, at this time, the controller 7 outputs a first rotation speed signal (for example, a reverse rotation signal) to the dc motor 1, controls the positive and negative pole change-over switch of the dc motor 1 to operate, so that the dc motor 1 rotates in a first rotation speed direction (for example, a reverse rotation direction), the rotation speed of the dc motor 1 is reduced by the gearbox 2, the humidity switch knob is adjusted by the mechanical arm 3 in the first rotation speed direction, and when the rotation angle of the dc motor 1 corresponding to the difference is controlled to rotate, the output of the first rotation speed signal to the dc motor 1 is stopped.
In order to ensure that the direct current motor 1 is in the direction (for example, the forward direction) opposite to the first rotation speed direction when being started next time, after the output of the first rotation speed signal to the direct current motor 1 is stopped, a reset signal is also output to the direct current motor 1, and the direct current motor 1 is restored to the original position by controlling the positive and negative pole change-over switch of the direct current motor 1, so that the direct current motor 1 is restored to the preparation state in the direction opposite to the first rotation speed direction.
When the difference value is a negative value, the humidity action value of the humidity switch 02 to be calibrated is lower than the preset humidity value, at this time, the controller 7 outputs a second rotating speed signal (for example, a forward rotation signal) to the direct current motor 1 to control the direct current motor 1 to rotate in a second rotating speed direction (for example, a forward rotation direction), the rotating speed of the direct current motor 1 is reduced through the gearbox 2, and then the humidity switch knob is adjusted in the second rotating speed direction through the mechanical arm 3, when the direct current motor 1 is controlled to rotate by a rotation angle corresponding to the difference value, a rotation speed signal (for example, a reverse rotation signal) opposite to the second rotation speed signal is output to the direct current motor 1, the direct current motor 1 is controlled to rotate in a direction (for example, a reverse rotation direction) opposite to the second rotation speed direction, when the dc motor 1 rotates in the reverse direction by a preset angle (obtained by using the return value of the humidity switch 02 to be calibrated), the output of the rotation speed signal in the direction opposite to the second rotation speed direction to the dc motor 1 is stopped.
It should be noted that when the current humidity action value of the humidity switch 02 to be calibrated is reduced, the direct current motor 1 may be controlled to rotate reversely, or the direct current motor 1 may be controlled to rotate forward; similarly, when the current humidity action value of the humidity switch 02 to be calibrated is increased, the direct current motor 1 may be controlled to rotate forward, or the direct current motor 1 may be controlled to rotate backward, and the forward rotation and the backward rotation of the direct current motor 1 are set according to actual requirements, which is not limited herein.
After the humidity switch 02 to be calibrated is calibrated, the humidity switch 02 to be calibrated can be repeatedly detected for many times to ensure the accuracy of calibration.
It can be understood by those skilled in the art that the humidity action value of the humidity switch can be specifically divided into a jump-up value and a jump-down value, the humidity switch can be actuated when the humidity of the environment exceeds the jump-up value, and can also be actuated when the humidity of the environment is lower than the jump-down value, and the calibration methods of the jump-down value and the jump-up value are similar.
If the difference value between the current humidity value and the preset humidity value is a positive value when the jump-up value is calibrated, the controller 7 controls the direct current motor 1 to rotate reversely; when the difference value is a negative value, the controller 7 controls the direct current motor 1 to rotate forward, and controls the direct current motor 1 to rotate backward when the rotation angle of the direct current motor 1 corresponds to the difference value.
When the down jump value is calibrated, the difference value between the current humidity value and the preset humidity value is a positive value, and the controller 7 controls the direct current motor to rotate forwards; when the difference value is a negative value, the controller 7 controls the direct current motor 1 to rotate reversely, and controls the direct current motor 1 to rotate forwards when the rotation angle of the direct current motor 1 corresponds to the difference value.
In conclusion, compared with manual calibration, the calibration method has the advantages that the humidity action value of the humidity switch 02 to be calibrated, namely the current humidity value transmitted by the standard humidity sensor 4 and the size relation of the preset humidity value can be automatically calibrated according to the acquired humidity action value of the humidity switch 02 to be calibrated, the whole calibration process is automated, so that calibration errors generated during manual calibration are eliminated, the labor intensity of workers is reduced, and the calibration efficiency is improved.
