Description

Technical Field

[0001] The present application relates to the field of fault detection technology, and in particular to the field of damper fault detection technology, and in particular to a damper fault detection method, device, medium and equipment. Background Art

[0002] In existing refrigeration systems, dampers are important components for regulating the direction and intensity of air flow. For example, in the refrigeration system of air-cooled refrigerators, dampers are generally provided. By controlling the opening and closing of the dampers, cold air can enter or stop entering the refrigerator's cold air passage through the dampers. However, the dampers may not be able to close normally during the opening and closing process due to ice accumulation or mechanical failure, which not only affects the refrigeration effect of the refrigerator, but may also cause damage to the equipment.

[0003] In order to ensure the normal operation of the damper and reduce the impact of faults, existing technologies usually rely on a single opening and closing detection device, such as using an air pressure sensor to collect environmental data to estimate the actual opening and closing angle of the damper, thereby determining whether the damper can be closed normally. Despite this, this single fault detection method still has certain limitations, because the accuracy of the currently used fault detection method cannot be ensured. Once the opening and closing detection device used for fault detection has a mechanical fault, misjudgment may occur, and the damper that was originally working in a normal state may be misjudged as an abnormal state, thereby triggering unnecessary early warning reminders. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0028] The embodiment of the present application provides a damper fault detection method, which can more accurately detect the abnormal state of the damper through multiple fault detection mechanisms, and effectively and promptly issue fault prompt information, thereby improving the stability of the refrigeration system and the user experience.

[0031] The damper fault detection method involved in the embodiment of the present application is mainly applied to electronic devices, which may be refrigerators, air conditioners, smart phones, tablet computers, laptop computers, desktop computers, and servers, etc., which are not limited here. Optionally, the server may be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or an IoT cloud (Internet of Things cloud) that provides the ability to store, process and manage data generated by an IoT TV, or a cloud server that provides cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and basic cloud computing services such as big data and artificial intelligence platforms, which are not limited here.

[0032] For ease of understanding, the specific process in the embodiments of the present application is described below. Figure 1 , Figure 1A schematic flow chart of an embodiment of a damper fault detection method provided in an embodiment of the present application.

[0033] exist Figure 1 In the embodiment shown, the method can be applied to electronic devices such as refrigerators or air conditioners that achieve temperature regulation by setting a damper. Taking a refrigerator as an example, the method specifically includes the following steps:

[0034] S101, obtaining first data collected by a first opening and closing degree detection device installed on the damper.

[0035] It should be explained that the air damper described in this application is a device for regulating air flow, which is usually installed in a ventilation system or a refrigeration system. Taking a refrigerator as an example, the air damper is mainly installed in the refrigeration system and plays its role. The air damper usually consists of a movable blade or multiple blades, which can be adjusted manually or automatically to allow or restrict air to pass through. The direction and intensity of the airflow are controlled by adjusting the blades of the air damper and then changing the degree of opening and closing of the air damper. The air damper can adopt different designs, such as parallel blade air dampers, double-opening air dampers, butterfly valves, etc., and can be selected according to specific application scenarios and needs. In an automated control system, the air damper usually works in conjunction with sensors and controllers to achieve the purpose of automatically regulating the airflow.

[0036] The first opening and closing degree detection device described in the present application refers to a detection device for detecting the opening and closing state of the damper. In some embodiments, the first opening and closing degree detection device takes an optical encoder as an example. The model of the optical encoder is E6C2-CWZ6C, and its measurement accuracy is 0.001 degrees, which can record the opening and closing angle of the damper in real time. By using the characteristic that the optical encoder can measure the angle by recording the change of the light signal, the opening and closing angle of the damper can be accurately detected, and then it can be determined whether the damper is normally opened or closed. In actual use, the optical encoder can be installed at the hinge of the damper, which can further improve the detection accuracy of the optical encoder for the opening and closing angle of the damper. At the same time, by utilizing the high precision and high reliability characteristics of the optical encoder, the fault type of the damper can be analyzed from different angles based on the light signal collected by the optical encoder (i.e., the first data described in the present application), such as damper jamming or abnormal opening and closing speed, etc., which will be specifically explained below.

[0037] In another embodiment, the first opening and closing degree detection device can also use an air pressure sensor. The model of the air pressure sensor is MPX5050, and its measurement accuracy is 0.1Pa, which can monitor air pressure changes in real time. The air pressure sensor can reflect the state of the gas by measuring the pressure of the gas, and indirectly reflect the working state of the damper, thereby assisting in determining whether the damper is normally open or closed. In actual use, the air pressure sensor can be installed on both sides of the damper. At the same time, the air pressure sensor can monitor the characteristics of air pressure changes, and can analyze the type of damper failure from different angles based on the air pressure value collected by the air pressure sensor (i.e., the first data described in the present application), such as poor sealing of the damper or abnormal opening and closing, etc., which will be specifically explained below.

[0038] It should be noted that the first opening and closing degree detection device described in the present application is not limited to the optical encoder and air pressure sensor listed above, but can also be other types of opening and closing detection devices, which are not limited here.

[0039] S102: Determine a first current opening / closing state of the damper according to the first data.

[0040] In this embodiment, when the first opening and closing degree detection device uses an optical encoder, the corresponding first data is the light signal collected by the optical encoder, and the first opening and closing state corresponding to different light signals can be obtained by using the light signal and a preset conversion rule. When the first opening and closing degree detection device uses an air pressure sensor, the corresponding first data is the air pressure value collected by the air pressure sensor, and the first opening and closing state corresponding to different air pressure values ​​can be obtained by using the air pressure value and a preset conversion rule.

[0041] S103, if the first opening and closing state is an abnormal state, obtaining second data collected by a second opening and closing degree detection device installed on the damper, wherein the opening and closing state determination basis corresponding to the first opening and closing degree detection device and the second opening and closing degree detection device is the same or different.

[0042] Considering that the accuracy of the currently used fault detection method cannot be ensured, once the opening and closing degree detection device used for fault detection has a mechanical fault, misjudgment may occur, and the damper that was originally working in a normal state may be misjudged as an abnormal state, thereby triggering unnecessary early warning reminders. Therefore, in this embodiment, by setting a second opening and closing degree detection device on the damper, and when the first opening and closing state is detected to be an abnormal state, the second data collected by the second opening and closing degree detection device is obtained, and the second data is combined to assist in determining the working state of the damper. The multiple fault detection mechanisms can more accurately detect the abnormal state of the damper.

[0043] It should be noted that the types of the first opening and closing degree detection device and the second opening and closing degree detection device can be the same or different. When the first opening and closing degree detection device and the second opening and closing degree detection device are of different types, that is, the fault judgment basis adopted by the two is different, it is possible to consider the factors affecting the normal operation of the damper from multiple aspects, and further improve the detection accuracy of the damper fault. The specific description of the second opening and closing degree detection device can refer to the above explanation of the first opening and closing degree detection device, and will not be repeated here.

[0044] S104: Determine a second current opening / closing state of the damper according to the second data.

[0045] In this embodiment, when the second opening and closing degree detection device uses an optical encoder, the corresponding second data is the light signal collected by the optical encoder, and the second opening and closing state corresponding to different light signals can be obtained by using the light signal and a preset conversion rule. When the second opening and closing degree detection device uses an air pressure sensor, the corresponding second data is the air pressure value collected by the air pressure sensor, and the second opening and closing state corresponding to different air pressure values ​​can be obtained by using the air pressure value and a preset conversion rule.

[0046] S105: If the second opening and closing state is an abnormal state, a damper fault prompt message is issued.

[0047] In this embodiment, when it is detected that both the first opening and closing state and the second opening and closing state are abnormal states, it can be determined with a high probability that the damper is faulty, and a damper fault prompt message is promptly issued to inform the user.

[0048] In this embodiment, through the multiple fault detection mechanisms, the abnormal state of the damper can be detected more accurately, and fault prompt information can be issued effectively and timely, thereby improving the stability of the refrigeration system and the user experience.

[0049] In some embodiments, determining the current first opening and closing state of the damper according to the first data includes:

[0050] If the first data is a first value collected at a corresponding unit time point, determining whether the first value falls within a preset first safety value range;

[0051] If not, it is determined that the current first opening and closing state of the damper is an abnormal state.

[0052] In this embodiment, when it is detected that the first data is the first value collected at the corresponding unit time point, it is determined whether the first value falls within the preset first safety value range, and whether the current first opening and closing state of the damper is an abnormal state according to the judgment result. When the judgment result is no, it is determined that the current first opening and closing state of the damper is an abnormal state. For example, when an optical encoder is selected as the first opening and closing degree detection device, the first value refers to the opening and closing angle of the damper. When the opening and closing angle of the damper exceeds the preset first safety value range (for example, the damper normally opens and closes between 0-90°, 0° means that the damper is fully closed, and 90° means that the damper is fully open), it means that the damper may have a fault at this time, resulting in abnormal opening and closing.

[0053] When an air pressure sensor is selected as the first opening and closing degree detection device, the first value refers to the air pressure value measured by the air pressure sensor. When the air pressure difference on both sides of the damper is within the preset first safety value range, it means that the sealing performance of the damper is poor at this time, and there may be a fault causing abnormal opening and closing.

[0054] In some embodiments, determining the current first opening and closing state of the damper according to the first data includes:

[0055] If the first data is a plurality of second values ​​collected within a corresponding preset time period, a value growth rate is calculated according to the plurality of second values, and it is determined whether the value growth rate falls within a preset second safety value range;

[0056] If not, it is determined that the current first opening and closing state of the damper is an abnormal state.

[0057] In this embodiment, when it is detected that the first data corresponds to a plurality of second values ​​collected within a preset time period, the value growth rate is first calculated based on the plurality of second values, and the data growth rate is used to analyze the growth speed of the first data within the preset time period, so as to reflect whether the speed of the damper opening and closing is abnormal. Specifically, it can be determined whether the value growth rate falls within the preset second safety value range. If not, it is determined that the current first opening and closing state of the damper is an abnormal state.

[0058] In some embodiments, determining the current first opening and closing state of the damper according to the first data includes:

[0059] When it is detected that the first data is changed compared with the historical data collected last time, determining whether the damper receives a damper control signal during the collection process from the historical data to the first data;

[0060] If not, it is determined that the current first opening and closing state of the damper is an abnormal state.

[0061] In this embodiment, when it is detected that the first data has changed compared with the historical data collected last time, it is determined whether the damper has received a damper control signal during the collection process from the historical data to the first data; if not, it means that the damper has opened and closed automatically without receiving the damper control signal, and the current first opening and closing state of the damper can be determined to be an abnormal state.

[0062] In some embodiments, Figure 2 As shown, the S105 includes:

[0063] S1051, if the second opening and closing state is an abnormal state, controlling the damper to repeatedly open and close a preset number of times, and simultaneously acquiring the currently collected first data and second data;

[0064] S1052, determining a third current opening / closing state of the damper according to the first data and the second data;

[0065] S1053: If the third opening and closing state is an abnormal state, a damper fault prompt message is issued.

[0066] It should be noted that, in the actual use of the refrigerator, ice and obstacles are likely to form at the air door, which will affect the normal closing and opening of the air door; or insufficient lubricating oil inside the air door, bad gears, etc., will also affect the normal closing and opening of the air door. In this embodiment, when the air door is not in a normal working state, the air door is controlled to open and close repeatedly for a preset number of times, and the preset number of times is at least twice. Specifically, when the air door is not in a normal opening state, the air door is controlled to close and open repeatedly for a preset number of times, and the first data and the second data currently collected are obtained at the same time, and the current third opening and closing state of the air door is determined according to the first data and the second data. If the third opening and closing state is an abnormal state, a warning message of an air door fault is issued.

[0067] It is understandable that by repeating the "on-off" action many times to generate vibration force, debris at the damper can be removed, and problems such as jamming caused by accidental temporary gear disengagement and temporary abnormalities in the control signal can be solved.

[0068] In some embodiments, Figure 3 As shown, the S1052 includes:

[0069] S10521: determining a first opening and closing state corresponding to the first data, and determining a second opening and closing state corresponding to the second data;

[0070] S10522 If the first opening and closing state or the second opening and closing state is an abnormal state, determine that the current third opening and closing state of the damper is an abnormal state.

[0071] In this embodiment, after multiple attempts to open and close the damper, if the first opening and closing state or the second opening and closing state is still in the state, it means that the simple mechanical opening and closing processing strategy cannot solve the current fault problem, and a damper fault prompt information needs to be issued in time.

[0072] In some embodiments, after determining the first current opening and closing state of the damper according to the first data, the method further includes:

[0073] If the opening and closing state judgment results corresponding to the first data within a preset period are all abnormal, a damper fault prompt message is issued.

[0074] In this embodiment, when it is detected that the first opening and closing state corresponding to the first data is in an abnormal state, it is also possible to determine whether the corresponding opening and closing states are all in abnormal states within a preset period by continuously measuring the first data for multiple times. If so, it means that the possibility of the damper failure is high, and there is no need to use the second opening and closing degree detection device to assist in determining whether the damper is in an abnormal state. At the same time, if the results of multiple measurements of the first opening and closing state are all in abnormal states, it may also be that there is an abnormality in the first opening and closing degree detection device.

[0075] All the above optional technical solutions can be arbitrarily combined to form optional embodiments of the present application, which will not be described one by one here.

[0076] In specific implementation, the present application is not limited by the execution order of the various steps described. If no conflict occurs, some steps can be performed in other orders or simultaneously.

[0077] As can be seen from the above, the damper fault detection method provided in the embodiment of the present application obtains the first data collected by the first opening and closing degree detection device installed on the damper; determines the current first opening and closing state of the damper according to the first data; if the first opening and closing state is an abnormal state, obtains the second data collected by the second opening and closing degree detection device installed on the damper, wherein the opening and closing state determination basis corresponding to the first opening and closing degree detection device and the second opening and closing degree detection device is the same or different; determines the current second opening and closing state of the damper according to the second data; if the second opening and closing state is an abnormal state, issues a damper fault prompt message. The damper fault detection method provided in the embodiment of the present application can detect the abnormal state of the damper more accurately through multiple fault detection mechanisms, and effectively and timely issues fault prompt messages, thereby improving the stability of the refrigeration system and the user experience.

The RF circuit 110 may include various existing circuit elements for performing these functions, such as an antenna, a radio frequency transceiver, a digital signal processor, an encryption / decryption chip, a user identity module (SIM) card, a memory, etc. The RF circuit 110 can communicate with various networks such as the Internet, an intranet, a wireless network, or communicate with other televisions via a wireless network.

[0113] The memory 120 can be used to store software programs and modules, such as the program instructions / modules corresponding to the damper fault detection method in the above embodiment. The processor 180 executes various functional applications and data processing by running the software programs and modules stored in the memory 120. The vibration reminder mode can be automatically selected according to the current scene of the electronic device to perform damper fault detection, which can not only ensure that scenes such as meetings are not disturbed, but also ensure that users can sense incoming calls, thereby improving the intelligence of the electronic device. The memory 120 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 120 may further include a memory remotely arranged relative to the processor 180, and these remote memories may be connected to the electronic device 1200 via a network. Examples of the above network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and a combination thereof.

[0114] The input unit 130 can be used to receive input digital or character information, and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, the input unit 130 may include a touch-sensitive surface 131 and other input devices 132. The touch-sensitive surface 131, also known as a touch display screen or touch pad, can collect user touch operations on or near it (such as operations performed by users using fingers, styluses, or any other suitable objects or accessories on or near the touch-sensitive surface 131), and drive corresponding connection devices according to a pre-set program. Optionally, the touch-sensitive surface 131 may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch position, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 180, and can receive and execute commands sent by the processor 180. In addition, the touch-sensitive surface 131 may be implemented in various types such as resistive, capacitive, infrared, and surface acoustic wave.

Subsequently, the processor 180 provides corresponding visual output on the display panel 141 according to the type of touch event. Although in Figure 6 In the embodiment, the touch-sensitive surface 131 and the display panel 141 are implemented as two independent components to realize the input and output functions.
