Example 1
In accordance with an embodiment of the present invention, there is provided an embodiment of a method for detecting a condition of a fan screen, where the steps illustrated in the flowchart of the drawings may be performed in a computer system, such as a set of computer executable instructions, and where a logical order is illustrated in the flowchart, in some cases the steps illustrated or described may be performed in an order different than that illustrated herein.
Fig. 1 is a flowchart of a method for detecting a state of a fan screen according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
and S102, acquiring the total running time of the fan and the preset rotating speed corresponding to the current gear of the fan.
Optionally, the fan may be, but is not limited to, a circulation fan, and fig. 2 shows a schematic structural diagram of an alternative circulation fan, as can be seen from fig. 2, the circulation fan includes a filter screen, an air speed sensor and a controller, wherein the controller is connected to the air speed sensor through a connection line, and the circulation fan further includes a machine head (not shown in fig. 2). The filter screen is installed in the income wind gap of circulation fan for air to getting into the circulation fan filters, blocks PM2.5, the wadding that floats, particulate matter, floating dust and bacterium etc. of suspension in the air. The wind speed sensor is arranged at the air outlet, detects wind speed in real time, transmits the detected wind speed value to the main control chip of the controller through the connecting wire, and the main control chip processes the wind speed to obtain the rotating speed corresponding to the wind speed.
It should be noted that the Filter screen may be, but is not limited to, a HEPA (High Efficiency Air Filter) Filter screen, and the controller includes, but is not limited to, a main control chip, a power supply, a display, and a buzzer, and is installed on the top of the circulation fan for controlling the operation of the circulation fan.
In addition, in the present application, the fan may have a plurality of (e.g., N) wind ranges, for example, the wind range when the fan normally operates is N1, and the rotation speed value is S1(ii) a The next gear is N2, and the corresponding rotating speed is S2(ii) a The next gear is N3, and the corresponding rotating speed is S3(ii) a By analogy, when the wind shield is Nx, the corresponding rotating speed is Sx。
And step S104, detecting the current rotating speed output by the fan under the current wind gear.
Optionally, as shown in fig. 2, the fan has an air speed sensor, which can monitor a real-time air speed output by an air outlet of the fan, and determine a real-time rotation speed corresponding to the fan according to the real-time air speed, where the real-time rotation speed is SaaAa is any value from 11 to the maximum gear xx of the fan, i.e. the real-time speed of the fan output is S11S to maximum gearxx。
And S106, comparing the total duration with a preset duration, and comparing the current rotating speed with a preset rotating speed to obtain a comparison result.
It should be noted that the fan further has a time chip and a power-off memory chip for counting the total time of the fan operation, wherein the longer the fan operation time is, the more dirty the filter screen of the fan is. In addition, when the filter screen of fan is in clean state, the current rotational speed of fan is close with the preset rotational speed that current gear corresponds, and when the difference between the two is great, can confirm that the filter screen needs to wash.
Therefore, whether the filter screen of the fan needs to be cleaned can be accurately determined through the step S106.
And S108, determining whether the filter screen of the fan is in an abnormal state according to the comparison result.
In step S108, if the filter screen needs to be cleaned, it is determined that the filter screen is in an abnormal state, otherwise, it is determined that the filter screen is in a normal state. Optionally, when the filter screen is determined to be in an abnormal state, the buzzer of the controller can be controlled to make a sound to remind a user that the filter screen needs to be cleaned, so that the user can clean the filter screen timely.
Based on the schemes defined in steps S102 to S108, it can be known that, in the embodiment of the present invention, a manner of determining whether the filter screen of the fan needs to be cleaned according to the total operating duration and the rotational speed of the fan is adopted, after the total operating duration of the fan and the preset rotational speed corresponding to the current windshield of the fan are obtained, a comparison result is obtained by detecting the current rotational speed output by the fan at the current windshield, comparing the total operating duration with the preset duration, and comparing the current rotational speed with the preset rotational speed, and finally, whether the filter screen of the fan is in an abnormal state is determined according to the comparison result.
It is easy to note that, in the above process, the current rotation speed of the fan represents the output wind speed corresponding to the fan, so that whether the output wind speed of the fan changes due to the filter screen being too dirty can be determined by detecting the total operation time of the fan and the current rotation speed of the fan, and then whether the filter screen of the fan needs to be cleaned can be accurately determined. In addition, in the process, the fan can automatically judge the state of the filter screen, so that a user can find the state in time when the filter screen is abnormal. In addition, in this application, the user need not dismouting fan can obtain the dirty degree of filter screen, has improved the experience that the user used the fan.
Therefore, the scheme provided by the application achieves the purpose of timely judging the state of the filter screen, so that the technical effect of improving the accuracy of judging the state of the filter screen is achieved, and the technical problem that whether the filter screen of the fan needs to be cleaned or not can not be accurately judged in the prior art is solved.
In an optional embodiment, before detecting whether a filter screen of the fan is in an abnormal state, the working time of the fan during working is firstly obtained, the working time is stored, and all the working time of the fan is counted to obtain the total time.
Optionally, fig. 3 shows a flowchart of an optional method for detecting a state of a filter screen of the fan, and as can be seen from fig. 3, after the fan is powered on, the fan starts to operate. When a user presses down a working switch of a main motor of the fan, the main control chip of the controller communicates with the time chip, wherein the time chip is used for recording the use duration of the fan, and the power-off memory chip stores the use duration of the fan each time the power is off, so that the stored data can be directly called when the fan is used next time.
Further, as shown in fig. 3, the user can set a preset duration T of the fan and a preset rotation speed S corresponding to each gearxMeanwhile, the controller acquires the current rotating speed S corresponding to the current wind speed detected by the wind speed sensorxx. And then, the controller determines whether the filter screen of the fan is in an abnormal state or not according to the comparison result of the total time length and the preset time length as well as the comparison result of the current rotating speed and the preset rotating speed.
Specifically, when the total duration is greater than or equal to the preset duration and the preset rotating speed is greater than the current rotating speed, first prompt information is generated, wherein the first prompt information is used for reminding of cleaning the filter screen. For example, in FIG. 3, when T ≧ Y, if the wind level of the fan is 1 st, the current rotation speed corresponding to the wind speed at the wind outlet detected by the wind speed sensor is S11And Y is the total running time of the fan. If S1＞S11(i.e., S in FIG. 3)x＞Sxx) And the situation that the air outlet rotating speed of the fan is not matched with the set rotating speed is shown, and the rest can be analogized in other gears. At the moment, the controller controls the LED lamp to flicker, intermittent buzzing for the first time is carried out at equal time intervals in the first duration, and the number of buzzing for each time is the second number, so that a user is reminded to clean the filter screen. The first time period may be one minute, the first number may be three times, and the second number may be three times.
The first time period, the first number of times, and the second number of times may be set according to actual conditions, and are not limited to the above-mentioned values.
In addition, after the first prompt message is generated, the first rotating speed of the fan after the fan operates for the first preset time is obtained, the first rotating speed is compared with the preset rotating speed, the filter screen is determined to be in a normal state under the condition that the first rotating speed is greater than the preset rotating speed, and second prompt message is generated, wherein the second prompt message is used for prompting other components of the fan to be abnormal. For example, in fig. 3, after a first preset duration (e.g., three minutes) of the first prompt message, the screen status of the fan screen is again checked, if S1＞S11(i.e., S in FIG. 3)x＞Sxx) And if so, indicating that the rotation speed difference of the fan is not caused by unclean filter screens, flashing a full screen of a display interface corresponding to the fan at the moment, and carrying out intermittent buzzing for a third time at equal time intervals by the buzzer within a second time length, wherein the number of buzzing for each time is a fourth number so as to remind a user to investigate whether other parts of the fan are abnormal or not. The second time period may be one minute, the third time period may be five times, and the third time period may also be five times.
The second time period, the third time and the fourth time may be set according to actual conditions, and are not limited to the above-mentioned values.
In an optional embodiment, when the total time length is greater than or equal to the preset time length and the difference between the preset rotating speed and the current rotating speed is less than the preset difference, the filter screen is determined to be in a normal state, and the fan is controlled to normally work. For example, in FIG. 3, when T ≧ Y, S1≈S11(i.e., S in FIG. 3)x≈Sxx) If the filter screen is cleaned before use or the filter screen is replaced by a new filter screen, the fan works normally and no prompt is given.
In an optional embodiment, when the total duration is less than the preset duration and the preset rotating speed is greater than the current rotating speed, the filter screen is determined to be in a normal state, and third prompt information is generated, wherein the third prompt information is used for reminding a motor of the fan that the motor works abnormally. For example, in FIG. 3, when T < Y, S1＞S11(i.e., S in FIG. 3)x＞Sxx) And if the motor works abnormally, directly judging that the motor works abnormally, and controlling the buzzer to conduct fifth intermittent buzzing at equal time intervals within a third time length by the controller of the fan, wherein the buzzing frequency is a sixth frequency every time so as to remind a user that the motor is abnormal. The third time period may be one minute, the fifth time period may be three times, and the sixth time period may be five times.
The third time period, the fifth time period and the sixth time period may be set according to actual conditions, and are not limited to the above-mentioned values.
In an alternative embodiment, when the total time length is less than the preset time length and the difference between the preset rotating speed and the current rotating speed is less than the preset difference, the filter screen is determined to be in a normal state, and the fan is controlled to normally work. For example, when T < Y, Sx≈SxxIf the difference between the preset rotating speed corresponding to the current gear of the fan and the real-time rotating speed is not large, the filter screen does not need to be cleaned, and the fan can work normally.
According to the method, the controller with the time chip and the power-off memory chip is used for operating on the fan, the using duration of the fan is counted and the last using data of the memory chip is read during each working, the preset rotating speed of the current gear and the current rotating speed detected in real time are compared in real time to judge whether the filter screen is accumulated with dust or not, and a user is reminded of cleaning the filter screen, so that the difference of the wind speed and the wind volume caused by the abnormal motor or the dirty air inlet filter screen can be intelligently judged. In addition, in the scheme that this application provided, the controller still can generate the filter screen when the filter screen is unusual and wash the reminder information, has improved the health nature and the travelling comfort that the user used the product.
