[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0044] It should be noted that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products, or devices.

[0045] It can be understood that the terms "first", "second", etc. used in the present application can be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish the first element from another element. For example, without departing from the scope of the present application, the first time length can be referred to as the second time length, and similarly, the second time length can be referred to as the first time length. Both the first time length and the second time length are time lengths, but they are not the same time length.

[0046] The embodiments of the present application disclose a dirt blockage detection method, device, electronic device, and storage medium, which can improve the efficiency and accuracy of dirt blockage detection. The following will be described in detail respectively.

[0047] Please refer toFigure 1 , Figure 1 is an application scenario diagram of a dirt blockage detection method disclosed in an embodiment of the present application. The dirt blockage detection method is applicable to the fan device 101, and a pressure sensor may be provided inside the fan device 101. The above-mentioned fan device may be disposed in an electronic device that needs to be cooled. Further, the above-mentioned fan device may be disposed in an electric control cabinet as a heat dissipation device of the electric control cabinet.

[0048] The fan device 101 can obtain the pressure data collected by the pressure sensor. If the pressure data is greater than a preset pressure threshold and maintains a preset first time length, it is determined that the fan device is in a dirt blockage state.

[0049] Figure 2 is a schematic flowchart of a dirt blockage detection method disclosed in an embodiment of the present application. Among them, Figure 2 the described dirt blockage detection method is applicable to the fan device. As Figure 2 shown, the dirt blockage detection method may include the following steps:

[0050] Step S202, obtain the pressure data collected by the pressure sensor.

[0051] In some embodiments, the fan device may be provided with a pressure sensor, and the pressure sensor may be disposed on the fan shaft of the fan device to detect the pressure data on the fan shaft. That is to say, the pressure data can be used to describe the pressure value on the fan shaft. Optionally, the fan device may also be provided with heat dissipation louvers to adjust the cooling degree of the fan device. Figure 3 is a structural diagram of a fan device in an embodiment. As Figure 3 shown, the heat dissipation louvers may be disposed on the front of the fan device. When the fan blades rotate, they drive the air flow, and the heat dissipation louvers can change the air flow passing through the fan device to adjust the cooling degree. Optionally, the fan device may also be provided with an air filter cotton to filter the dust in the air and reduce the dust in the air from entering the fan device. Figure 4 is a structural diagram of a fan device in an embodiment. As Figure 4 shown, a pressure sensor is disposed on the fan shaft of the fan device, and an air filter cotton is disposed between the fan blades and the heat dissipation louvers to filter the air flow driven by the rotation of the fan blades, thereby reducing the dust in the flowing air flow from entering the fan device.

[0052] As an alternative implementation, the pressure sensor of the fan device can obtain the pressure data collected by the pressure sensor every preset time period to ensure real-time acquisition of the pressure data corresponding to the fan device. For example, the fan device can control the pressure sensor to collect pressure data every 0.1 seconds. The fan device can also control the pressure sensor to collect pressure data every preset time period, and compare the currently collected pressure data with the historical pressure data collected last time. If the currently collected pressure data is different from the historical pressure data collected last time, then obtain the currently collected pressure data. For example, assume that the fan device controls the pressure sensor to collect pressure data every 1 second, and the pressure data collected by the pressure sensor at 15:00:01 is A Pa. If the pressure data collected by the pressure sensor at 15:00:00 is B Pa, then the fan device can obtain the pressure data collected at 15:00:01. By comparing the currently collected pressure data with the historical pressure data collected last time and obtaining the pressure data different from the historical pressure data, the redundancy of the obtained pressure data can be reduced, thereby improving the efficiency of processing the pressure data.

[0053] In some embodiments, the fan device further includes a pressure transducer and a PLC controller. The pressure transducer, the PLC controller, and the pressure sensor can form a pressure detection circuit of the fan device, and transmit the pressure data collected by the pressure sensor to the PLC controller of the fan device through the pressure detection circuit, so that the fan device can process the pressure data. Figure 5 is a schematic structural diagram of the pressure detection circuit in an embodiment, as Figure 5 shown, when the fan device reads the pressure data, it can be the pressure transmitter that reads the pressure data collected by the pressure sensor and converts the read pressure data into an analog value. Specifically, the range of this analog value can be 4 - 20 mA and 0 - 10 V. The fan device transmits this analog value to the PLC controller so that the fan device can obtain the pressure data and process the pressure data. Optionally, the fan device can transmit the obtained pressure data to the central control system through the Internet of Things with a wireless connection. The central control system can process the pressure data and generate a clogging prompt corresponding to the fan device when it determines that the fan device is in a clogged state, so as to quickly notify the maintenance personnel to clean the fan device.

[0054] Step S204, if the pressure data is greater than a preset pressure threshold and has been maintained for a preset first time length, then determine that the fan device is in a clogged state.

[0055] In some embodiments, after the fan device obtains the pressure data, it can judge the pressure data. If the pressure data is greater than a preset pressure threshold and maintains for a preset first time length, it is determined that the fan device is in a dirty blockage state. Among them, the pressure threshold can be obtained by analyzing historical pressure data, and the preset first time length can be determined according to the sensitivity of detecting dirty blockage required by the user. The lower the required sensitivity of detecting dirty blockage, the longer the first time length can be set; the higher the required sensitivity of detecting dirty blockage, the shorter the first time length can be set. For example, the first time length can be set to 10 minutes.

[0056] Furthermore, the fan device can obtain multiple historical pressure data sets; the historical pressure data set is the historical pressure data collected within a preset third time length; according to the data stability values corresponding to each historical pressure data set, the target historical pressure data set is selected, and the average value of the historical pressure data in the target historical pressure data set is used as the pressure threshold. The fan device can obtain multiple historical pressure data sets collected within the third time length. The third time length for collecting these historical pressure data sets can be continuous or discontinuous, which is not limited here. The data stability value corresponding to each historical pressure data set can be used to describe the magnitude of the difference between the multiple historical pressure data in the historical pressure data set. Generally speaking, the larger the data stability value corresponding to the historical pressure data set, the smaller the difference between the multiple historical pressure data in the historical pressure data set. After determining the target historical pressure data set, the fan device can remove the maximum value and the minimum value from the target historical pressure data set, then calculate the average value of the historical pressure data after removing the maximum value and the minimum value, and use this average value as the pressure threshold.

[0057] The fan device selects the target historical pressure data set according to the data stability values corresponding to each historical pressure data set, and uses the average value of the historical pressure data in the target historical pressure data set as the pressure threshold, which can analyze the historical pressure data set to obtain the pressure threshold, thereby improving the accuracy of judging the pressure data according to the pressure threshold and providing a technical basis for improving the accuracy of detecting the dirty blockage state of the fan device.

[0058] Further, the fan device can calculate the differences between the respective historical pressure data in the historical pressure data set, and calculate the average value of the differences between the respective historical pressure data as the data stability value corresponding to each historical pressure data; select the historical pressure data set with the smallest data stability value corresponding to each historical pressure data as the target historical pressure data set. The fan device can calculate the differences between every two historical pressure data in the historical pressure data set, and calculate the average value of the differences between every two historical pressure data as the data stability value corresponding to each historical pressure data. For example, assuming that the historical pressure data set includes historical pressure data A, historical pressure data B, and historical pressure data C, the differences between historical pressure data A and historical pressure data B, historical pressure data A and historical pressure data C, and historical pressure data B and historical pressure data C are calculated respectively, and the average value of the three differences is calculated to obtain the data stability value corresponding to the historical pressure data set.

[0059] The fan device calculates the differences between the respective historical pressure data in the historical pressure data set, and calculates the average value of the differences between the respective historical pressure data as the data stability value corresponding to each historical pressure data, which can improve the rationality of the calculated pressure threshold.

[0060] In some embodiments, the fan device can detect the clogging condition of the fan device according to the pressure data through a clogging detection model trained by historical pressure data, and obtain the clogging state corresponding to the fan device. Among them, the clogging state corresponding to the fan device can be used to describe the degree of clogging of the fan device. For example, the clogging state can be no clogging, slight clogging, and heavy clogging, etc. The clogging can also be divided into two types: having clogging and no clogging, which is not specifically limited. The clogging detection model in the fan device can first extract data features from the pressure data to obtain pressure features, and classify the pressure features, and the classification result can be used as the clogging state corresponding to the fan device. The clogging detection model can be trained by historical pressure data. The fan device can obtain a historical pressure data set, which can include multiple historical pressure data and the target clogging state corresponding to each historical pressure data. Input the historical pressure data set into the clogging detection model to be trained. The clogging detection model to be trained obtains the predicted clogging state corresponding to each historical pressure data according to each historical pressure data, and adjusts the clogging detection model to be trained according to the error between the target clogging state corresponding to each historical pressure data and the predicted clogging state corresponding to each historical pressure data until the error is less than a preset error threshold, so as to obtain the trained clogging detection model.

[0061] The fan device can detect the clogging condition of the fan device through the clogging detection model, which further improves the accuracy of detecting the clogging of the fan device.

[0062] In an embodiment of the present application, the fan device acquires the pressure data collected by the pressure sensor; if the pressure data is greater than a preset pressure threshold and maintains for a preset first time length, it is determined that the fan device is in a blocked state. The fan device can acquire the pressure data collected by the pressure sensor. When the pressure data is greater than the preset pressure threshold and maintains for the preset first time length, it is determined that the fan device is in a blocked state. It can directly detect the blocked state of the fan device according to the pressure data corresponding to the fan device, without relying on manual judgment of the blocked state. And when the pressure data is greater than the preset pressure threshold and maintains for the first time length, it is determined that the fan is in a blocked state, avoiding misjudgment of the blocked state due to errors in the pressure data acquisition within a short period of time, and improving the blocked detection efficiency and accuracy.

[0063] Figure 6 is a flowchart of another blocked detection method disclosed in an embodiment of the present application. As Figure 6 shown, the blocked detection method may include the following steps:

[0064] Step S602, acquire the temperature data collected by the temperature sensor.

[0065] In one embodiment, the fan device may also be provided with a temperature sensor. Specifically, the temperature sensor may be disposed at a place where the temperature of the air flow passing through the fan device can be detected. For example, the temperature sensor may be disposed on the inner wall of the fan device.

[0066] As an optional implementation manner, the temperature sensor of the fan device acquires the temperature data in the fan device at the same frequency as the pressure sensor acquires the pressure data, so as to ensure that the fan device can process the temperature data and the pressure data simultaneously.

[0067] Step S604, if the temperature data is greater than a preset temperature threshold and maintains for a preset second time length, it is determined that the fan device is in a blocked state.

[0068] In some embodiments, after the fan device acquires the temperature data, it can judge the temperature data. If the temperature data is greater than a preset temperature threshold and maintains for a preset second time length, it is determined that the fan device is in a blocked state. Among them, the temperature threshold may also be obtained by analyzing historical temperature data. The preset second time length can be determined according to the sensitivity required by the user for detecting blockage. The lower the required sensitivity for detecting blockage, the longer the second time length can be set; the higher the required sensitivity for detecting blockage, the shorter the second time length can be set. For example, the second time length can be set to 10 minutes.

[0069] In another embodiment, the fan device can obtain the temperature data collected by the temperature sensor; if the pressure data is greater than a preset pressure threshold within a first time period, and the temperature data is greater than a preset temperature threshold within a second time period, it is determined that the fan device is in a blocked state. The fan device can determine that the fan device is in a blocked state only when the pressure data is greater than the preset pressure threshold within the first time period and the temperature data is greater than the preset temperature threshold within the second time period, thereby further improving the accuracy of the blocked detection of the fan device. Optionally, the fan device can also input the temperature data and the pressure data into a blocked detection model. The blocked detection model can extract features from the temperature data and the pressure data to obtain the total data features, and classify the total data features. The obtained classification result can be used as the blocked state corresponding to the fan device. Among them, the blocked detection model can be trained by a historical temperature data set and a historical pressure data set. The fan device performs blocked detection according to the temperature data and the pressure data through the blocked detection model, which can improve the accuracy and efficiency of the blocked detection of the fan device.

[0070] As an optional implementation manner, the fan device can obtain the operation state signal corresponding to the fan device; if the operation state signal indicates that the fan device is in an on state, the pressure data collected by the pressure sensor is obtained. Among them, the operation state signal can be used to indicate the operation condition of the fan device. Specifically, the operation state signal corresponding to the fan device can include an on state and an off state. Among them, the on state can be used to indicate that the fan device is currently in a startup operation condition, and the off state can be used to indicate that the fan device is currently in a stop operation condition. The operation state signal corresponding to the fan device can be generated according to a user instruction input by the user. For example, the user can input a user instruction to control the fan device to turn on through voice input or manual control input, so that the fan device controls the fan device to be in an on state according to the user instruction. The fan device obtains the pressure data collected by the pressure sensor when the operation state signal indicates that the fan device is in an on state, which can avoid obtaining pressure data when there is no need to detect blockage, thereby reducing the energy consumption of the fan device.

[0071] Optionally, the fan device can also obtain the temperature data collected by the temperature sensor if the operation state signal indicates that the fan device is in an on state, which can avoid obtaining invalid temperature data, thereby further reducing the energy consumption of the fan device.

[0072] In the embodiment of the present application, the fan device obtains the temperature data collected by the temperature sensor. If the temperature data is greater than a preset temperature threshold and maintains a preset second time period, it is determined that the fan device is in a blocked state, avoiding errors in the pressure data collection within a short time, thereby causing misjudgment of the blocked state, and improving the blocked detection efficiency and accuracy.
