Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
As described in the background art, the existing monitoring method of the ion blower has a problem that the ion balance voltage output by the fan airflow fluctuates greatly when the ion blower is turned off. The inventor researches and finds that the technical problem is caused by the fact that when a power switch of the ion blower is turned off, the power supply module stops supplying power to the fan and the high-voltage module. At this time, there is no high voltage output on the electrode needle, and it is impossible to continue to maintain the field ionization of the positive and negative ions, but the positive ions and electrons near the electrode needle continue to undergo secondary ionization, and the secondary ionization capacity of the negative ions is greater than that of the positive ions, so the number of the positive and negative ions generated by the secondary ionization is different, and the fluctuation of the ion balance voltage in the space near the electrode needle is large. However, after the power supply module stops supplying power to the fan, the fan can continue to rotate due to inertia, positive ions and negative ions with large ion balance voltage fluctuation in the space near the electrode needle are conveyed to the surface of the charged object, ideal electricity eliminating performance cannot be achieved, and even the electric charge quantity on the surface of the charged object can be aggravated to form reverse electrification. For example, the number of negative ions output by the ion blower is greater than the number of positive ions, which is equivalent to applying a negative voltage to the surface of the charged object, and the amount of negative charges on the surface of the charged object is increased, thereby affecting the usability of the ion blower.
Fig. 1 is a schematic flow diagram of a monitoring method for an ion blower according to an embodiment of the present invention, where the embodiment of the present invention is applicable to monitoring an ion blower in a use process, the monitoring method may be executed by a monitoring device, the monitoring device is implemented in a software and/or hardware manner, and the monitoring device may be configured in a controller (e.g., a single chip microcomputer) of the ion blower or in an upper computer. The ion blower further comprises a fan, a high-voltage module and a power supply module. Referring to fig. 1, the monitoring method of the ion blower includes the following steps:
and S110, detecting the power switch state of the ion fan.
The power switch state is the on or off state of a power switch of the ion fan. The power switch of the ion blower may be, for example, a power switch such as a tact switch or a touch switch, or may be a power switch signal output from the controller.
And S120, if the power switch of the ion fan is detected to be turned off, controlling the power supply module to stop supplying power to the fan, and determining whether the fan is in a rotating state.
Because the rotation of the fan has certain inertia, after the power supply module stops supplying power to the fan, the fan may continue to rotate due to the inertia, and positive and negative ions are conveyed to the surface of the charged object through the fan airflow.
And S130, if the fan is in a rotating state, controlling the power supply module to supply power to the high-voltage module.
The high-voltage module applies high voltage to the electrode needle according to a control signal output by the controller to form point discharge and ionize air to form positive ions and negative ions. The control power supply module can maintain positive and negative ions formed by ionizing air by point discharge to keep balance in the process of supplying power to the high-voltage module, and maintain the fluctuation of ion balance voltage in a controllable range.
According to the embodiment of the invention, by detecting the power switch state of the ion blower, if the power switch of the ion blower is detected to be turned off, the power supply module is controlled to stop supplying power to the fan, whether the fan is in a rotating state or not is determined, and if the fan is in the rotating state, the power supply module is controlled to supply power to the high-voltage module, so that the effect of delaying power failure of the high-voltage module when the power switch is turned off is realized. Compared with the prior art, the embodiment of the invention avoids the problem that the fan continues to rotate to convey positive ions and negative ions with larger fluctuation of the ion balance voltage to the surface of a charged object when the power switch of the ion blower is turned off, thereby reducing the fluctuation of the ion balance voltage output by the fan airflow, ensuring that the ion balance voltage does not exceed the fluctuation range of the standard voltage, keeping the ion balance voltage stable and improving the performance of the ion blower.
In the above embodiments, there are various methods for determining whether the fan is in a rotating state, and several typical determination methods are described below, but the present invention is not limited thereto.
Optionally, determining whether the fan is in a rotating state comprises: detecting the loop current of the fan, and if the loop current is greater than a first preset current, enabling the fan to be in a rotating state; if the loop current is less than or equal to the first preset current, the fan is in a stop state.
The rotation of the fan is driven by the motor, and the loop current of the fan is the loop current of the stator of the motor. As can be understood by those skilled in the art, the operation of the motor is bidirectional, and when the motor is in an electric state, the motor converts electric energy into kinetic energy to drive the fan to rotate; when the power supply module stops supplying power to the fan, the motor can continue to operate due to the inertia effect, the motor is in a power generation state at the moment, the motor converts kinetic energy into electric energy, loop current is generated in the stator loop, and the loop current is positively correlated with the rotating speed of the motor. Therefore, whether the fan is in a rotating state can be judged by judging the magnitude of the loop current.
The first preset current may be zero or a small value greater than zero, so that the wind force of the fan cannot output the positive and negative ions to the surface of the charged object. The embodiment of the invention determines whether the fan is in the rotating state by detecting the loop current of the fan, has lower cost and simple implementation method.
Optionally, determining whether the fan is in a rotating state may further include: detecting the running time of the fan after the power switch is turned off, and if the running time is longer than the preset time, enabling the fan to be in a rotating state; and if the running time is less than or equal to the preset time, the fan is in a stop state.
When the power switch of the fan is turned off, the power supply module stops supplying power to the fan, and the time range required by the fan from the rotating state to the stopping state is measurable. The preset time can be the time required by the fan from a high-speed rotation state to a low-speed rotation state, and can also be longer. The embodiment of the invention determines whether the fan is in the rotating state by detecting the running time of the fan after the power switch is turned off, so that the cost is lower and the implementation method is simple.
Fig. 2 is a schematic flow chart of another monitoring method for an ion blower according to an embodiment of the present invention. Referring to fig. 2, on the basis of the foregoing embodiments, optionally, before detecting a power switch state of the ion blower, the method further includes: detecting the loop current of the fan, and if the loop current is smaller than a second preset current or the loop current is larger than a third preset current, outputting an abnormal mark signal of the fan; the second predetermined current is less than the third predetermined current. Namely, the monitoring method of the ion fan comprises the following steps:
s210, detecting the loop current of the fan, and outputting an abnormal mark signal of the fan if the loop current is smaller than a second preset current or the loop current is larger than a third preset current.
The second preset current is smaller than the third preset current, the second preset current may be a current when the fan rotates at a lower speed, and the third preset current may be a current when the fan rotates at a higher speed. The loop current is an important index of the running state of the fan, and the magnitude of the loop current reflects the running state of the fan. If the loop current is between the second preset current and the third preset current, the fan operates normally; if the loop current exceeds the current range, the fan fails. For example, when the fan is locked, the loop current increases sharply.
And S220, detecting the power switch state of the ion fan.
And S230, if the power switch of the ion blower is detected to be turned off, controlling the power supply module to stop supplying power to the fan, and determining whether the fan is in a rotating state.
And S240, if the fan is in a rotating state, controlling the power supply module to supply power to the high-voltage module.
According to the embodiment of the invention, the running state of the fan can be monitored in real time by detecting the loop current of the fan and judging whether the fan fails according to the magnitude of the loop current, and when the fan fails, a fan failure alarm is sent out in time, so that the problem that ions cannot be output to the surface of a charged object due to the stop of the fan is avoided, the performance of the ion blower is further improved, and the safe and stable running of the ion blower is facilitated.
Fig. 3 is a schematic flow chart of a monitoring method of an ion blower according to another embodiment of the present invention. Referring to fig. 3, on the basis of the foregoing embodiments, before detecting the power switch state of the ion blower, optionally, the method further includes: acquiring an electrofluid field signal detected by an electrofluid field monitoring module; if the value of the electrofluid field signal exceeds the numerical range of a preset test data set, outputting an ion balance abnormal mark signal; the preset test data set is a data set corresponding to the detected electrofluid field signal, wherein the plurality of ion balance voltages of the ion fan are within the preset ion balance voltage range. Namely, the monitoring method of the ion fan comprises the following steps:
and S310, acquiring an electrofluid field signal detected by the electrofluid field monitoring module.
Among them, the electric fluid field is a complex physical field formed by three physical fields. Taking fig. 4 as an example for explanation, referring to fig. 4, the ion blower includes a fan 100, an electrode needle 200, and a front metal detection mesh 300. The collection unit of the electrofluid field monitoring module can be, for example, the front metal detection mesh 300 of the ion blower. The electrofluidic field includes: the space flow charge field formed by the positive and negative ions ionized by the ion blower (e.g., the positive and negative ion distributions in fig. 4), the airflow field powered by the fan 100 (e.g., the airflow field moving in the direction 600 in fig. 4), and the high-pressure field on the electrode needle 200. The three physical fields simultaneously exist in the space of the metal detection mesh enclosure 300 of the ion blower, so that a complex electrofluid field is formed.
The principle of collecting the electrofluid field by the collecting unit is that a high-voltage field on the electrode needle 200 generates an induction electric field in the collecting unit to form induction current; the electric potential of the collecting unit is low, and when positive ions and negative ions move towards the collecting unit, a part of the positive ions and the negative ions collide with the collecting unit to form ion current. The electrofluid field monitoring module further performs AD sampling, data processing and other operations on the current signals acquired by the acquisition unit, and outputs the processed electrofluid field signals to the monitoring device. Those skilled in the art will appreciate that the electrofluidic field monitoring module may also be part of the monitoring device of the ion blower.
And S320, if the value of the electrofluid field signal exceeds the numerical range of the preset test data set, outputting an ion balance abnormal mark signal.
The preset test data set is a data set corresponding to the detected electrofluid field signal, wherein the plurality of ion balance voltages of the ion fan are within the preset ion balance voltage range. The data set may include a plurality of values or may be one or more ranges of values. The ion balance voltage of the ion fan and the electrofluid field signal have a corresponding relation, and if the ion balance voltage is in a preset ion balance voltage range, the value of the electrofluid field signal is in a preset electrofluid field value range. Therefore, by limiting the signal of the preset electrofluidic field to the value range of the preset test data set, it can be ensured that the ion balance voltage is within the preset ion balance voltage range.
Illustratively, the preset test data set is obtained in such a way that the ion blower operates normally, the ion balance voltage is detected to be within a preset ion balance voltage range by the flat panel tester, and the ion balance voltage can be changed within the preset ion balance voltage range by adjusting positive and negative voltages output by the ion blower, for example, the preset ion balance voltage range is [ -30V,30V ]; meanwhile, the electrofluid field signals are detected by the electrofluid field monitoring module, and a plurality of groups of electrofluid field signals are detected along with the change of the electrofluid field signals, namely a preset test data group, for example, the numerical range of the preset test data group is [ -1.1V,0.4V ].
Fig. 5 is a schematic diagram illustrating a correspondence relationship between an electrofluidic field signal and an ion balance voltage according to an embodiment of the present invention. Referring to fig. 5, there is a corresponding relationship between the ion balance voltage and the electric fluid field signal, wherein the ion balance voltage includes an average value of the ion balance voltage, a maximum value of the ion balance voltage, and a minimum value of the ion balance voltage. And taking the average value of the ion balance voltage as a reference, if the electric fluid field signal exceeds the range of [ -1.1V,0.3V ], the average value of the ion balance voltage exceeds the range of [ -30V,30V ], and the monitoring device outputs an ion balance abnormal mark signal.
S330, detecting the power switch state of the ion fan.
S340, if the fact that a power switch of the ion fan is turned off is detected, controlling a power supply module to stop supplying power to the fan, and determining whether the fan is in a rotating state.
And S350, if the fan is in a rotating state, controlling the power supply module to supply power to the high-voltage module.
According to the embodiment of the invention, the preset test data set of the electrofluid field is obtained, whether the value of the electrofluid field signal exceeds the numerical range of the preset test data set or not is judged according to the preset test data set, if the value of the electrofluid field signal exceeds the numerical range of the preset test data set, an ion balance abnormal mark signal is output, and the ion balance voltage can be accurately monitored in real time. The embodiment of the invention improves the effectiveness of the monitoring method for monitoring the ion balance voltage, avoids the phenomena of no output of the ion balance abnormal mark signal when the ion balance voltage has larger fluctuation or the error output of the balance abnormal mark signal when the ion balance voltage has not larger fluctuation, and the like, ensures the positive and negative ion balance and electricity elimination performance of the ion fan, and further improves the performance stability of the ion fan.
Fig. 6 is a schematic flow chart of a monitoring method of an ion blower according to another embodiment of the present invention. Referring to fig. 6, on the basis of the foregoing embodiments, optionally, acquiring an electrofluidic field signal detected by the electrofluidic field monitoring module includes: continuously collecting a plurality of electrofluid field signals detected by an electrofluid field monitoring module; if the electrofluid field signal exceeds the value of the preset test data set, an ion balance abnormal flag signal is output, including: and if the average value of the collected multiple electrofluid field signals exceeds the numerical range of the preset test data set, outputting an ion balance abnormal mark signal. Namely, the monitoring method of the ion fan comprises the following steps:
s410, continuously collecting a plurality of electrofluid field signals detected by the electrofluid field monitoring module.
And S420, if the average value of the collected multiple electrofluid field signals exceeds the numerical range of a preset test data set, outputting an ion balance abnormal mark signal.
The average of the plurality of electrofluidic field signals may be, for example, an arithmetic average, a geometric average, a squared average, a harmonic average, a weighted average, and the like. Optionally, before calculating the average value of the plurality of electrofluidic field signals, abnormal signal values in the electrofluidic field signals may also be rejected. The embodiment of the invention further avoids the interference of external abnormal signals in the monitoring process and improves the monitoring effectiveness.
Optionally, after outputting the ion balance abnormality flag signal, the method further includes: if the ion balance abnormal signal is a positive voltage large signal, controlling to reduce the positive voltage ratio output by the ion fan or increase the negative voltage ratio output by the ion fan; and if the ion balance abnormal signal is a negative voltage larger signal, controlling to reduce the negative voltage ratio output by the ion fan or increase the positive voltage ratio output by the ion fan. The positive voltage duty ratio output by the ion blower is reduced, for example, the positive voltage acting time (positive voltage duty ratio) is reduced or the amplitude of the positive voltage output by the positive high voltage module is reduced. The proportion of the negative voltage output by the ion blower is increased, for example, the action time of the negative voltage (negative duty ratio) is increased or the amplitude of the negative voltage output by the negative high-voltage module is increased. The negative voltage ratio output by the ion blower is reduced, for example, the negative voltage acting time (negative voltage duty ratio) is adjusted to be low or the amplitude of the negative voltage output by the negative high-voltage module is reduced. The positive voltage duty ratio output by the ion blower may be, for example, to increase the positive voltage application time (positive voltage duty ratio) or to increase the amplitude of the positive voltage output by the positive high voltage module. Set up like this, can be when the malleation is bigger than normal, control ion fan exports more anions, reduces ion balance voltage to and can be when the negative pressure is bigger than normal, control ion fan exports more positive ions, reduces ion balance voltage.

Referring to fig. 8, the monitoring apparatus of the ion blower includes: a power state detection module 810, a fan state determination module 820, and a high voltage power control module 830. The power state detection module 810 is configured to detect a power switch state of the ion blower. The fan state determination module 820 is configured to control the power supply module to stop supplying power to the fan and determine whether the fan is in a rotation state if it is detected that the power switch of the ion blower is turned off. The high voltage power supply control module 830 is used for controlling the power supply module to supply power to the high voltage module if the fan is in a rotating state.
The embodiment of the invention is provided with a power state detection module 810, a fan state determination module 820 and a high-voltage power supply control module 830, wherein the power state detection module 810 is used for detecting the power switch state of the ion blower, the fan state determination module 820 is used for controlling the power supply module to stop supplying power to the fan and determining whether the fan is in a rotating state or not if the fan state determination module 820 detects that the power switch of the ion blower is turned off, and the high-voltage power supply control module 830 is used for controlling the power supply module to supply power to the high-voltage module if the fan is in the rotating state, so that the effect of delayed power off of the high-voltage module when the power switch is turned off is realized. Compared with the prior art, the embodiment of the invention avoids the problem that the fan continues to rotate to convey positive ions and negative ions with larger fluctuation of the ion balance voltage to the surface of a charged object when the power switch of the ion blower is turned off, thereby reducing the fluctuation of the ion balance voltage output by the fan airflow, ensuring that the ion balance voltage does not exceed the fluctuation range of the standard voltage, keeping the ion balance voltage stable and improving the performance of the ion blower.
