In an exemplary embodiment of the present application, the air outlet device may include, but is not limited to: air conditioner, fan with wind channel, etc.

In exemplary embodiments of the present application, it is known that current concealed air ducts cannot identify whether the air duct is normal; the air duct is dirty and blocked, and the user cannot sense the air duct; the air leakage of the air duct affects the use of users, so the hidden air duct has many problems. Based on the problems, the embodiment of the application provides an air duct detection method based on constant air volume, the control mode of the constant air volume can output the same air volume for different air ducts, the user experience cannot be influenced no matter whether the air duct is abnormal or not, and the static pressure of the air duct can be judged through the change of the motor operation data based on the control of the constant air volume, so that whether the current air duct is abnormal or not can be correspondingly judged.

In the exemplary embodiment of the application, the scheme of the embodiment of the application can be applied to a hidden air duct and also can be applied to a non-hidden air duct, and the automatic detection of the abnormity of the air duct can be realized. And no matter to hidden wind channel or non-hidden wind channel, can all realize the preliminary judgement to the wind channel condition, saved the manual check operation of user to the wind channel by a wide margin, consequently can improve user's use experience to a certain extent and feel.

In an exemplary embodiment of the present application, said controlling the wind outlet device to operate at a constant wind rate may include:

determining the currently selected operation gear of the air outlet equipment; wherein, different operation gears can be in one-to-one correspondence with different air volumes;

and controlling the motor of the air outlet equipment to rotate in a PWM (pulse width modulation) control mode so that the air outlet equipment can output a constant air volume matched with the selected operation gear.

In an exemplary embodiment of the present application, controlling the air outlet device to operate at a constant air volume is a precondition for implementing a scheme of the embodiment of the present application, in order to achieve that the air outlet device outputs a constant air volume, the motor rotation speed of the air outlet device may be controlled in a PWM control manner, and in the process of outputting the air volume, the output air volume may be detected in real time and fed back to a control device (such as a processor described in the following contents), the control device may perform PID (proportional, integral, differential) adjustment on the motor rotation speed according to the fed back air volume, and for the mediation result, the control on the motor rotation speed may be achieved in the PWM control manner.

In an exemplary embodiment of the present application, the method may further include:

the correspondence of different operating steps (i.e., air volume) to different PWM values may be predetermined.

In the exemplary embodiment of the application, in order to realize the fast control of the air outlet device, different operation gears may be measured in advance, or a PWM control value corresponding to the air volume may be output, so that the air outlet device is directly controlled according to the set PWM control value when the constant air volume control is performed.

In the exemplary embodiment of this application, can preset a plurality of operation gears to air-out equipment, different operation gears can correspond different amount of wind, promptly the operation gear can with the amount of wind one-to-one.

In an exemplary embodiment of the present application, for example, a low operation gear (may be referred to as a low gear), a medium operation gear (may be referred to as a medium gear), and a high operation gear (may be referred to as a high gear) may be provided, where the low operation gear may correspond to the first air volume, the medium operation gear may correspond to the second air volume, and the high operation gear may correspond to the third air volume. And the first air volume is smaller than the second air volume, and the second air volume is smaller than the third air volume.

In the exemplary embodiment of the present application, as shown in table 1, specific examples of the first air volume, the second air volume, and the third air volume corresponding to the low operation gear, the middle operation gear, and the high operation gear are respectively given.

TABLE 1

In an exemplary embodiment of the present application, the method may further include:

aiming at each operation gear, the corresponding relation between different air duct static pressures and different standard motor operation data under the same operation gear can be respectively determined;

the size of the air duct static pressure can be used for representing whether the current air duct is abnormal or not and different abnormal conditions corresponding to the abnormal air duct.

In the exemplary embodiment of the present application, after the air outlet device (e.g., an air conditioner) is opened, the air outlet of the air outlet device may be connected to the air inlet of the air duct, and based on the control of the constant air volume of the air outlet device, the air volume in the air duct may not change due to the static pressure of the air duct (the static pressure of the air duct may change according to the structural change of the air duct, for example, when the air duct is blocked or broken, the static pressure of the air duct may change, and therefore, the abnormal situation of the air duct may be reflected by the change of the static pressure of the air duct), but along with the change of the static pressure of the air duct, if it is desired to keep the constant air volume running all the time, it is inevitable to change the motor running data in the running process of the motor. Therefore, the static pressure change of the air duct can be determined through the change of the click operation data of the air outlet equipment in the constant air volume operation process, so that whether the air duct of the air outlet equipment is abnormal or not can be determined.

In the exemplary embodiment of the present application, based on the above principle, standard motor operation data corresponding to different duct static pressures may be respectively measured at the same air flow rate, that is, at the same operation gear, and the standard motor operation data may be used as a basis for determining the magnitude of the current duct static pressure, that is, after the current motor operation data is detected, the detected motor operation data may be compared with a plurality of pre-measured standard motor operation data (the plurality of standard motor operation data respectively correspond to different duct static pressures one by one), and it may be determined which standard motor operation data of the plurality of pre-measured standard motor operation data matches the detected motor operation data, and the matched standard motor operation data may be obtained, and accordingly, the duct static pressure corresponding to the matched standard motor operation data may be determined, the air duct static pressure is the air duct static pressure of the air duct of the current air outlet equipment. On the basis of determining the air duct static pressure of the current air duct, the abnormal condition of the air duct can be judged according to the air duct static pressure.

In an exemplary embodiment of the present application, the foregoing matching may mean that an absolute value of a difference between two numerical values is less than a preset difference threshold, and the mismatch may mean that the absolute value of the difference between two numerical values is greater than or equal to the preset difference threshold.

In the exemplary embodiment of the present application, as shown in table 1 above, the corresponding relationship between different duct static pressures and different standard motor operation data in each operating range can also be given in the low operating range, the middle operating range and the high operating range respectively.

In an exemplary embodiment of the present application, before comparing the motor operation data with a preset data threshold, the method may further include:

and acquiring standard motor operation data corresponding to the air duct static pressure of the air outlet equipment under the normal condition, and taking the standard motor operation data corresponding to the air duct static pressure under the normal condition as the data threshold.

In an exemplary embodiment of the present application, the air duct static pressures in the normal air duct condition and the abnormal air duct condition are different, and in order to determine whether the air duct is abnormal according to the air duct static pressure, the air duct static pressure in the normal air duct condition and the standard motor operation data corresponding to the air duct static pressure may be determined first, and the standard motor operation data corresponding to the air duct static pressure in the normal air duct condition may be used as a determination standard of the currently detected motor operation data, that is, the standard motor operation data corresponding to the air duct static pressure in the normal air duct condition is used as the data threshold.

In the exemplary embodiment of the present application, the static pressure of the air duct under normal conditions may be different according to different air duct structures, materials, sizes, installation environments, and other factors, and the static pressure of the air duct under normal conditions is not particularly limited herein.

In exemplary embodiments of the present application, for example, the normal duct static pressure may include, but is not limited to, 50 Pa.

In the exemplary embodiment of the application, the static pressure of the air duct can be used for representing whether the current air duct is abnormal or not and different corresponding abnormal conditions when the air duct is abnormal; moreover, corresponding relations exist between different air duct static pressures and different standard motor operation data; therefore, different standard motor operation data can be directly corresponding to different air duct conditions (including normal air duct conditions and abnormal air duct conditions), and the detected current motor operation data does not need to be matched with corresponding air duct static pressure firstly, and then the current air duct conditions are judged according to the air duct static pressure. The embodiment scheme can correspondingly reduce the data processing amount and improve the data processing efficiency, thereby improving the judgment speed of the air channel condition.

In an exemplary embodiment of the present application, determining whether the air duct of the air outlet device is abnormal according to a comparison result of the two, may include:

the motor operation data is equal to the data threshold value, and the air duct is determined to be normal;

and determining that the air duct is abnormal when the motor operation data is larger than or smaller than the data threshold.

In the exemplary embodiment of the present application, it can be known from the foregoing solution that the data threshold may be standard motor operation data under the determined normal condition of the air duct, and therefore, comparing the motor operation data detected in real time with the data threshold may determine whether the air duct is in a normal state.

In the exemplary embodiment of the present application, the data threshold may be a specific numerical value, or may be a set data range, and the specific implementation manner of the data threshold is not limited herein. When the data threshold is a set data range, the data values greater than or less than the data threshold (or not matched with the data threshold) are both outside the data range, and the data values equal to or matched with the data threshold are equal to or within the boundary value of the data range.

In an exemplary embodiment of the present application, if the motor operation data matches the data threshold, it may be determined that the air duct is in a normal state, and if the motor operation data does not match the data threshold, it may be determined that the air duct is in an abnormal state.

In an exemplary embodiment of the present application, the matching described above may include: the motor operating data is exactly equal to the data threshold (which may satisfy a predetermined numerical float range, e.g., may satisfy the difference threshold). The mismatch may include: the motor operating data is greater than or less than the data threshold.

In an exemplary embodiment of the present application, the method may further include:

after the air duct is determined to be abnormal, judging the abnormal condition according to the size of the motor operation data; and/or the presence of a gas in the gas,

and after the air duct is determined to be abnormal, determining the static pressure of the air duct according to the operation data of the motor, and judging the abnormal condition according to the static pressure of the air duct.

In the exemplary embodiment of the application, the static pressure of the air duct can be used for representing whether the current air duct is abnormal or not and different corresponding abnormal conditions when the air duct is abnormal; moreover, corresponding relations exist between different air duct static pressures and different standard motor operation data; therefore, different motor operation data detected at present can be directly corresponding to different air duct abnormal conditions, the specific abnormal conditions of the air duct can be judged according to the size of the motor operation data, or the motor operation data detected at present can be firstly corresponding to different air duct static pressures, after the current air duct static pressure is determined, the specific abnormal conditions of the current air duct can be judged according to the size of the current air duct static pressure.

In an exemplary embodiment of the present application, as shown in fig. 2, the determining the abnormal condition of the air duct according to the size of the motor operation data may include:

when the motor operation data is larger than the data threshold value, the blockage of the air duct can be judged;

and when the motor operation data is smaller than the data threshold value, the air leakage of the air duct can be judged.

In an exemplary embodiment of the present application, determining the magnitude of the static pressure of the air duct according to the magnitude of the motor operation data may include:

when the motor operation data is larger or smaller than the data threshold value, the current air duct static pressure can be judged to be larger or smaller than the air duct static pressure under the normal condition of the air duct.

In the exemplary embodiment of the present application, similarly, when the motor operation data is equal to the data threshold, it may be determined that the current duct static pressure is equal to the duct static pressure in the normal condition of the duct.

In an exemplary embodiment of the present application, in a case where it is determined that the current duct static pressure is equal to the duct static pressure in the case where the duct is normal, it may be determined that the current duct is in the normal state.

In the exemplary embodiment of the application, under the condition that it is determined that the current air duct is in a normal state, the air outlet device and the air duct can be normally used, and the detected motor operation data is continuously fed back in real time, so that whether the air duct is abnormal or not is continuously judged according to the motor operation data.

In an exemplary embodiment of the present application, when it is determined that the current static pressure of the air duct is greater than or less than the static pressure of the air duct under the normal condition of the air duct, the determining, according to the magnitude of the static pressure of the air duct, a specific abnormal condition of the current air duct may include:

when the current air duct static pressure is larger than the air duct static pressure under the normal condition of the air duct, the blockage of the air duct can be judged;

and when the current air duct static pressure is smaller than the air duct static pressure under the normal condition of the air duct, the air duct leakage can be judged.

In the exemplary embodiment of the present application, when it is determined that the air duct is clogged, it is indicated that foreign matter or dirt is present in the air duct, and the user may be prompted to clean the air duct.

In an exemplary embodiment of the application, in the process of constant air volume operation of the air outlet device, the motor operation current may be detected, and the currently detected motor operation current is compared with the standard motor operation currents corresponding to different air duct static pressures measured in advance at the current operation gear, so as to obtain the standard motor operation current matched with the standard motor operation currents, and the air duct static pressure corresponding to the matched standard motor operation current is used as the air duct static pressure of the current air duct, so that whether the current air duct is abnormal or not and specific abnormal conditions (for example, air duct blockage and air duct leakage) when the air duct is abnormal may be determined according to the determined current air duct static pressure; specifically, the current air duct static pressure may be compared with the air duct static pressure in the normal state of the air duct, and if the current air duct static pressure is greater than or less than the air duct static pressure in the normal state of the air duct, it may be determined that the air duct is abnormal, and if the current air duct static pressure is equal to the air duct static pressure in the normal state of the air duct, it may be determined that the air duct is normal.

In the exemplary embodiment of the present application, as shown in fig. 3, for the currently detected motor operating current, the current motor operating current may also be directly compared with a standard motor operating current (i.e., the aforementioned numerical threshold, which may be a current threshold) under a normal condition of the air duct, and according to a comparison result, whether the current air duct is abnormal or not and specific abnormal conditions (for example, air duct blockage and air duct leakage) under an abnormal condition of the air duct are directly determined; specifically, if the current motor operating current is greater than or less than the standard motor operating current in the normal state of the air duct, it may be determined that the air duct is abnormal, and if the current motor operating current is equal to the standard motor operating current in the normal state of the air duct, it may be determined that the air duct is normal.

In the exemplary embodiment of the application, in the process of performing constant air volume operation on the air outlet device, the operation power of the motor may be detected, the currently detected operation power of the motor is compared with the operation power of the standard motor corresponding to different air duct static pressures measured in advance at the current operation gear, so as to obtain the standard operation power of the motor matched with the operation power of the standard motor, and the air duct static pressure corresponding to the matched standard operation power of the motor is used as the air duct static pressure of the current air duct, so that whether the current air duct is abnormal or not and specific abnormal conditions (for example, air duct blockage and air duct leakage) when the air duct is abnormal may be determined according to the determined current air duct static pressure.

In the exemplary embodiment of the present application, as shown in fig. 4, for the currently detected motor operating power, the currently detected motor operating power may also be directly compared with the standard motor operating power under the normal condition of the air duct (i.e. the aforementioned numerical threshold, which may be a power threshold), and according to the comparison result, whether the current air duct is abnormal or not and the specific abnormal conditions (for example, air duct blockage and air duct leakage) when the air duct is abnormal are directly determined; specifically, if the current motor operating power is greater than or less than the standard motor operating power in the normal state of the air duct, it may be determined that the air duct is abnormal, and if the current motor operating power is equal to the standard motor operating power in the normal state of the air duct, it may be determined that the air duct is normal.

In the exemplary embodiment of the application, in the process of constant air volume operation of the air outlet device, the motor operation torque may be detected, the currently detected motor operation torque is compared with the standard motor operation torques corresponding to different air duct static pressures measured in advance at the current operation gear, so as to obtain the standard motor operation torque matched with the standard motor operation torques, and the air duct static pressure corresponding to the matched standard motor operation torque is used as the air duct static pressure of the current air duct, so that whether the current air duct is abnormal or not and specific abnormal conditions (for example, air duct blockage and air duct leakage) when the air duct is abnormal may be determined according to the determined current air duct static pressure.
