Description

Technical Field

[0001] This application relates to the field of air conditioning monitoring, and more particularly to an air conditioning monitoring method, apparatus, air conditioning equipment, and storage medium. Background Technology

[0002] With global warming and improved living standards, more and more families are installing and using air conditioners, leading to a sharp increase in air conditioner usage. Typically, the outdoor unit of an air conditioner operates in a much harsher environment than the indoor unit. Changes in outdoor temperature, sunlight, air humidity, and the installation environment all have a significant impact on the entire piping system of the outdoor unit. Especially when the air conditioner is running, because the outdoor unit is usually installed outside the wall, it is difficult to detect abnormalities in the piping. The stress on the piping at various points is constantly changing. When the stress exceeds the standard, it can cause deformation and rupture of the piping, resulting in refrigerant leakage. This can affect the normal operation of the air conditioner and endanger people's lives and property. Furthermore, since the outdoor unit is usually installed outside the wall, the cost and difficulty of repairing any malfunctions are relatively high. Summary of the Invention

[0048] Figure 1 This is a diagram illustrating the application environment of an air conditioning monitoring method in one embodiment. (Refer to...) Figure 1 This air conditioning monitoring method is applied to air conditioning equipment, which specifically includes an outdoor unit 110, an indoor unit 120, and an air conditioning monitoring device 130. The outdoor unit 110 and the indoor unit 120 are electrically connected, and the outdoor unit 110 and the indoor unit 120 are respectively connected to the air conditioning monitoring device 130 via a network. The outdoor unit 110 includes a piping system, as shown in the reference. Figure 2 The pipeline system includes multiple pipeline key points, and each pipeline key point is equipped with a stress sensor, which is used to detect stress changes at the pipeline key points.

[0049] In one embodiment, Figure 2 This is a flowchart illustrating an air conditioning monitoring method in one embodiment, with reference to... Figure 2 This invention provides a method for monitoring air conditioning. This embodiment primarily applies this method to the aforementioned... Figure 1 Taking the air conditioning monitoring device 130 as an example, the air conditioning monitoring method specifically includes the following steps:

[0050] Step S210: Obtain the piping system parameters of the outdoor unit 110 in the air conditioning equipment, wherein the piping system parameters include the detection stress of multiple key points in the piping system of the outdoor unit 110.

[0051] Specifically, the key points of the pipeline are the critical points in the pipeline system that are prone to generating large stresses based on testing. The stress at the key points of the pipeline is obtained by stress sensors placed at the key points.

[0052] Step S220: Determine the abnormal state of the outdoor unit 110 based on the pipeline system parameters.

[0053] Specifically, the outdoor unit 110 is judged to be in an abnormal state based on the detection stress at each key point of the pipeline. This can be done by combining the detection stress of all key points of the pipeline, or by judging the detection stress of a single key point of the pipeline.

[0054] Step S230: Control the operating parameters of the air conditioning equipment according to the abnormal state of the outdoor unit 110, so as to restore the abnormal state of the outdoor unit 110 to the normal state.

[0055] Specifically, once the outdoor unit 110 is determined to be in an abnormal state, the operating parameters of the air conditioning equipment are adjusted based on the abnormal state of the outdoor unit 110 to reduce the detection stress at key points in the piping system, thereby restoring the abnormal state of the outdoor unit 110 to a normal state. This solves the problem that existing technologies cannot cope with abnormal situations in the piping of the outdoor unit 110, and prevents the air conditioning equipment from continuing to operate in the original mode without timely detection of the abnormality of the outdoor unit 110, which could lead to pipe deformation and rupture, causing refrigerant leakage. This avoids affecting the normal use of the air conditioning and the safety of people's lives and property, can extend the service life of the air conditioning equipment, and improve the safety of the air conditioning equipment.

[0056] In one embodiment, determining the abnormal state of the outdoor unit 110 based on the piping system parameters includes:

[0057] The abnormal state of the outdoor unit 110 is determined based on the preset stress range to which the target detection stress of the target pipeline key point belongs and the preset duration range to which the stress duration corresponding to the target detection stress belongs. The target pipeline key point is any pipeline key point in the pipeline system of the outdoor unit 110.

[0058] Specifically, the detected stress at each key point of the pipeline is compared with the preset stress range corresponding to that key point, and the stress duration of the detected stress at each key point is compared with the corresponding preset duration range to determine whether the outdoor unit 110 is operating abnormally due to overstress. That is, the abnormal state of the outdoor unit 110 is accurately determined based on the detected stress and stress duration of each key point of the pipeline. When the detected stress and stress duration of the key points of the pipeline are different, the pipeline system of the outdoor unit 110 is in different working states. The working states are divided into normal and abnormal states of different levels. This allows for real-time detection of the pipeline system stress of the air conditioning equipment under different actual usage scenarios, and timely detection of the abnormal state of the outdoor unit 110 based on the pipeline system stress. This enables timely adjustment of the operating parameters of the air conditioning equipment to address the abnormal state of the outdoor unit 110 and eliminate the abnormal state of the outdoor unit 110.

[0059] In one embodiment, refer to Figure 4 The determination of the abnormal state of the outdoor unit 110 based on the preset stress range to which the target detection stress of the key point of the target pipeline belongs and the preset duration range to which the stress duration corresponding to the target detection stress belongs includes at least one of the following:

[0060] When the target detection stress is within a first stress range and the stress duration is within a first duration range, the first abnormal state is determined as the abnormal state of the outdoor unit 110.

[0061] When the target detected stress is within the first stress range and the stress duration is within the second duration range, or when the target detected stress is within the second stress range and the stress duration is within the third duration range, the second abnormal state is determined as the abnormal state of the outdoor unit 110, wherein the lower limit of the second duration range is greater than the upper limit of the first duration range.

[0062] When the target detected stress is within the second stress range and the stress duration is within the fourth duration range, or when the target detected stress is within the third stress range and the stress duration is within the fifth duration range, the third abnormal state is determined as the abnormal state of the outdoor unit 110, wherein the lower limit of the fourth duration range is greater than the upper limit of the third duration range.

[0063] When the target detection stress is within the third stress range and the stress duration is within the sixth duration range, the fourth abnormal state is determined as the abnormal state of the outdoor unit 110. The abnormality level increases sequentially from the first abnormal state to the fourth abnormal state, the stress gradually increases from the first stress range to the third stress range, and the lower limit of the sixth duration range is greater than the upper limit of the fifth duration range.

[0064] Specifically, the first stress range is [f] n1 ,f n2 ), f n1 For the first preset stress, f n2 The second preset stress is denoted as f, the target detection stress is denoted as t, and the stress duration is denoted as t. The first duration range is less than the first preset duration t. n1 That is, f n2 >f≥f n1 And t < t n1 When, that is, the actual detected stress exceeds f n1 If the duration is short, then the outdoor unit 110 is determined to be in the first abnormal state.

[0065] The second stress range is [f] n2 ,f n3 ), where f n3 The third preset stress is defined as follows: the second time period is greater than or equal to the first preset time period, and the third time period is less than the second preset time period t. n2 , in f n2 >f≥f n1 And t≥t n1 , or f n3 >f≥f n2 And t < t n2 When, it indicates that the actual detected stress exceeds f. n1 The duration t≥tn1 Or the actual measured stress exceeds f n2 Duration t < t n2 This indicates that the actual detected pipeline stress has reached the warning response level. Although the air conditioning pipeline stress here exceeds the standard, it is still within the acceptable range and will not affect the overall operation of the air conditioning equipment. Therefore, it is determined that the outdoor unit 110 is in the second abnormal state.

[0066] The third stress range is greater than or equal to the third preset stress, and the fourth duration range is greater than or equal to the second preset duration t. n2 The fifth duration range is less than the third preset duration t. n3 , in f n3 >f≥f n2 And t≥t n2 , or f≥f n3 And t < t n3 When, that is, the actual detected stress exceeds f n2 The duration t≥t n2 This indicates that the actual detected pipeline stress has reached the rapid response level. At this point, the air conditioning pipeline stress has significantly exceeded the standard, and a more effective treatment plan is needed to prevent it from affecting the subsequent normal operation of the air conditioner. Therefore, it is determined that the outdoor unit 110 is in the third abnormal state.

[0067] The sixth duration range is greater than or equal to the third preset duration, that is, when f ≥ f n3 And t≥t n3 When, that is, the actual detected stress exceeds f n3 The duration t≥t n3 This indicates that the actual pipeline stress detected at this time has reached the shutdown response level. At this point, there is a risk of damage to the air conditioning pipeline. If the air conditioning equipment continues to operate, it will cause huge losses. Therefore, it is determined that the outdoor unit 110 is in the fourth abnormal state.

[0068] Where f n1 <f n2 <f n3 , t n1 >t n2 >t n3 Different abnormal states correspond to different abnormal levels, with the first abnormal state having the lowest level and the fourth abnormal state having the highest level. Different response strategies are adopted for different abnormal levels. The correspondence between response strategies and abnormal states is shown in Table 1 below:

[0069] Stress threshold Duration Display level Early warning response <![CDATA[f n1 ]]> <![CDATA[t n1 ]]> yellow Rapid Response <![CDATA[f n2 ]]> <![CDATA[t n2 ]]> orange color Stop response <![CDATA[f n3 ]]> <![CDATA[t n3 ]]> red

[0070] Table 1

[0071] As shown in Table 1, the response strategy for the second abnormal state is an early warning response, the response strategy for the third abnormal state is a rapid response, and the response strategy for the fourth abnormal state is a shutdown response. Different response strategies are adopted for different abnormal states of outdoor unit 110 to quickly eliminate the abnormal state of outdoor unit 110. In addition, the system can output corresponding display levels for different abnormal states, providing clear and visible display colors for back-end staff, so that back-end staff can clearly grasp the stress status of each key point of the pipeline.

[0072] In one embodiment, controlling the operating parameters of the air conditioning equipment based on the abnormal state of the outdoor unit 110 includes:

[0073] When the abnormal state of the outdoor unit 110 is the first abnormal state, the air conditioning unit is controlled to continue operating according to the current operating parameters.

[0074] Specifically, refer to Figure 4 When the abnormal state of outdoor unit 110 is the first abnormal state, it means that the detection stress of the key point of the target pipeline has reached the first stress range. However, since the stress duration is insufficient, the air conditioning equipment can still operate normally. Therefore, the air conditioning equipment is controlled to continue to operate normally according to the current operating parameters, and no abnormal correction action will be taken for the first abnormal state to avoid affecting the temperature control effect of the air conditioning equipment by making abnormal corrections in the first abnormal state.

[0075] In one embodiment, controlling the operating parameters of the air conditioning equipment based on the abnormal state of the outdoor unit 110 includes:

[0076] When the abnormal state of the outdoor unit 110 is the second abnormal state, the temperature difference between the indoor ambient temperature and the set temperature is obtained;

[0077] When the temperature difference is within a first temperature difference range, the compressor frequency of the air conditioning unit is switched from the current compressor frequency to a first compressor frequency, wherein the operating parameters include the compressor operating frequency, and the first compressor frequency is the sum of the current compressor frequency and the first adjustment frequency; or,

[0078] When the temperature difference is within the second temperature difference range, the compressor frequency of the air conditioning equipment is switched from the current compressor frequency to the second compressor frequency, wherein the second compressor frequency is the sum of the current compressor frequency and the second adjustment frequency, the second adjustment frequency is less than the first adjustment frequency, and the lower limit of the first temperature difference range is greater than the upper limit of the second temperature difference range; or,

[0079] When the temperature difference is within the third temperature difference range, the compressor frequency of the air conditioning equipment is controlled to switch from the current compressor frequency to the third compressor frequency, wherein the third compressor frequency is the difference between the current compressor frequency and the first adjustment frequency, and the lower limit of the second temperature difference range is greater than the upper limit of the third temperature difference range.

[0080] Specifically, refer to Figure 4 When the abnormal state of outdoor unit 110 is the second abnormal state, a warning response is selected as the response strategy corresponding to the second abnormal state. The abnormal correction method corresponding to the warning response is based on the temperature difference ΔT between the indoor ambient temperature and the set temperature. An adjustment frequency corresponding to the temperature difference range is selected and adjusted based on the current compressor frequency. By adjusting the compressor operating frequency, the stress condition of key points in the piping system of outdoor unit 110 is changed, avoiding the detection stress of key points in the piping system from being continuously maintained under high stress conditions. The temperature difference ΔT is the absolute value of the difference between the indoor ambient temperature and the set temperature. When the air conditioner is working in cooling mode, ΔT = indoor ambient temperature - set temperature. When the air conditioner is working in heating mode, ΔT = set temperature - indoor ambient temperature. The better the actual cooling and heating effect, the smaller ΔT is; the worse the actual cooling and heating effect, the larger ΔT is.

[0081] The first temperature difference range is greater than or equal to the first preset temperature difference ΔT1. That is, when ΔT≥ΔT1, the first adjustment frequency ΔF1 is added to the current compressor frequency F, that is, the first compressor frequency is F+ΔF1. In this scenario, the temperature difference between the indoor ambient temperature and the set temperature is the largest, indicating that the temperature control effect of the air conditioning equipment is the worst. Therefore, it is necessary to increase the compressor operating frequency to a large extent to improve the cooling or heating capacity of the air conditioning equipment, thereby reducing the difference between the indoor ambient temperature and the set temperature. That is, while optimizing the temperature control effect of the air conditioning equipment, the compressor operating frequency is dynamically adjusted to avoid the current compressor frequency corresponding to the large detection stress at the current pipeline key point, and to avoid the compressor operating frequency continuously increasing the detection stress at the pipeline key point by maintaining the current operating frequency.

[0082] The second temperature difference range is [ΔT2, ΔT1), where ΔT2 is the second preset temperature difference. When ΔT1 > ΔT ≥ ΔT2, a second adjustment frequency ΔF2 is added to the current compressor frequency F, i.e., the second compressor frequency is F + ΔF2, where ΔT1 > ΔT2 and ΔF1 > ΔF2. In this scenario, the temperature difference between the indoor ambient temperature and the set temperature is smaller than that in the previous scenario. Therefore, the indoor temperature control effect is better than in the previous scenario. A slight increase in the compressor operating frequency is needed to improve the cooling or heating capacity of the air conditioning unit, thereby further reducing the difference between the indoor ambient temperature and the set temperature. The compressor operating frequency is dynamically adjusted while optimizing the air conditioning unit's temperature control effect, thus avoiding the current compressor frequency corresponding to high detection stress at key pipeline points. This prevents the compressor operating frequency from continuously increasing the detection stress at key pipeline points due to maintaining the current operating frequency.

[0083] The third temperature difference range is less than the second preset temperature difference. When ΔT < ΔT2, the first adjustment frequency is subtracted from the current compressor frequency F, i.e., the third compressor frequency is F - ΔF1. In this scenario, the temperature difference between the indoor ambient temperature and the set temperature is small, indicating good indoor temperature control. Therefore, the compressor operating frequency can be reduced to a greater extent to reduce the cooling or heating capacity of the air conditioning equipment, thereby saving the compressor's operating energy consumption. It only needs to maintain the indoor ambient temperature. The compressor operating frequency is dynamically adjusted while ensuring the temperature control effect of the air conditioning equipment, thereby avoiding the current compressor frequency corresponding to the high detection stress at the current pipeline key point, and preventing the compressor operating frequency from continuously increasing the detection stress at the pipeline key point.

[0084] In one embodiment, controlling the operating parameters of the air conditioning equipment based on the abnormal state of the outdoor unit 110 includes:

[0085] When the abnormal state of the outdoor unit 110 is the third abnormal state, the temperature difference between the indoor ambient temperature and the set temperature is obtained;

[0086] When the temperature difference is within the first temperature difference range, the compressor frequency of the air conditioning equipment is switched from the current compressor frequency to a fourth compressor frequency, wherein the operating parameters include the compressor operating frequency, and the fourth compressor frequency is the sum of the current compressor frequency and the third adjustment frequency; or,

[0087] When the temperature difference is within the second temperature difference range, the compressor frequency of the air conditioning equipment is switched from the current compressor frequency to a fifth compressor frequency, wherein the fifth compressor frequency is the sum of the current compressor frequency and a fourth adjustment frequency, the fourth adjustment frequency is less than the third adjustment frequency, the fourth adjustment frequency is greater than the first adjustment frequency, and the lower limit of the first temperature difference range is greater than the upper limit of the second temperature difference range; or,

[0088] When the temperature difference is within the third temperature difference range, the compressor frequency of the air conditioning equipment is switched from the current compressor frequency to the sixth compressor frequency, wherein the sixth compressor frequency is the difference between the current compressor frequency and the third adjustment frequency, and the lower limit of the second temperature difference range is greater than the upper limit of the third temperature difference range.

[0089] Specifically, refer to Figure 4 When the abnormal state of outdoor unit 110 is the third abnormal state, a rapid response is selected as the response strategy corresponding to the third abnormal state. The abnormal correction method corresponding to the rapid response is based on the temperature difference ΔT between the indoor ambient temperature and the set temperature. An adjustment frequency corresponding to the temperature difference range is selected and adjusted based on the current compressor frequency. By adjusting the compressor operating frequency, the stress condition of key points in the piping system of outdoor unit 110 is changed, avoiding the detection stress of key points in the piping from being continuously maintained under high stress conditions. However, the adjustment frequency corresponding to the rapid response is greater than the adjustment frequency corresponding to the early warning response.

[0090] The third adjustment frequency is ΔF3, and the fourth adjustment frequency is ΔF4, where ΔF3 > ΔF4 > ΔF1 > ΔF2. When ΔT ≥ ΔT1, the third adjustment frequency is added to the current compressor frequency to obtain the fourth compressor frequency, which is F + ΔF3. Due to the high detection stress in the third abnormal state, when the temperature difference between the indoor ambient temperature and the set temperature is the largest, i.e., when the temperature control effect of the air conditioning equipment is poor, it is necessary to maximize the increase of the compressor operating frequency to improve the cooling or heating capacity of the air conditioning equipment. This can not only quickly reduce the difference between the indoor ambient temperature and the set temperature, but also quickly switch the compressor operating frequency from the current compressor frequency to the compressor frequency corresponding to other frequency bands. This quickly changes the compressor operating frequency band with high detection stress, dynamically adjusting the compressor operating frequency while optimizing the temperature control effect of the air conditioning equipment. This avoids the current compressor frequency corresponding to the current high detection stress at the key points of the pipeline, preventing the compressor operating frequency from continuously increasing the detection stress at the key points of the pipeline.

[0091] When ΔT1>ΔT≥ΔT2, the temperature control effect in this scenario is better than that in the previous scenario. Therefore, the compressor adjustment frequency is lower than that in the previous scenario. A fourth adjustment frequency is added to the current compressor frequency to obtain the fifth compressor frequency, which is F+ΔF4. Due to the high detection stress in the third abnormal state, when the temperature difference between the indoor ambient temperature and the set temperature is large, it is necessary to increase the compressor operating frequency to a greater extent to reduce the temperature difference between the indoor ambient temperature and the set temperature, thereby optimizing the indoor temperature control effect. Increasing the compressor operating frequency to a greater extent can improve the cooling or heating capacity of the air conditioning equipment. This can not only quickly reduce the difference between the indoor ambient temperature and the set temperature, but also quickly switch the compressor operating frequency from the current compressor frequency to the compressor frequency corresponding to other frequency bands. This can quickly change the compressor operating frequency band with high detection stress. By dynamically adjusting the compressor operating frequency while optimizing the temperature control effect of the air conditioning equipment, the current compressor frequency corresponding to the current high detection stress at the key points of the pipeline can be avoided, thus preventing the compressor operating frequency from continuously increasing the detection stress at the key points of the pipeline.

[0092] When ΔT < ΔT2, it indicates good temperature control, and there is no need to further increase the cooling or heating capacity. The third adjustment frequency is subtracted from the current compressor frequency F, resulting in the sixth compressor frequency being F - ΔF3. In this scenario, the temperature difference between the indoor ambient temperature and the set temperature is small, indicating good indoor temperature control. Therefore, the compressor operating frequency can be significantly reduced to decrease the cooling or heating capacity of the air conditioning unit, thus saving compressor energy consumption. It only needs to maintain the indoor ambient temperature. Furthermore, the compressor operating frequency can be quickly switched from the current frequency to the corresponding frequency in other frequency bands to rapidly change the compressor operating frequency band with high detection stress. This dynamic adjustment of the compressor operating frequency, while ensuring the temperature control effect of the air conditioning unit, avoids the current compressor frequency corresponding to high detection stress at key pipeline points, preventing the compressor from continuously increasing the detection stress at key pipeline points by maintaining the current operating frequency.

[0093] Based on the different response strategies mentioned above, graded treatment can be implemented for different pipeline stress conditions. This can reduce the pipeline stress of the pipeline system under different pipeline stress conditions, thereby solving the problem of difficult maintenance of outdoor unit 110 pipeline abnormalities, extending the service life of outdoor unit 110, and improving the reliability, stability and safety of air conditioning equipment.

[0094] In one embodiment, controlling the operating parameters of the air conditioning equipment based on the abnormal state of the outdoor unit 110 includes:

[0095] When the abnormal state of the outdoor unit 110 is the fourth abnormal state, the air conditioning equipment is controlled to stop.

[0096] Specifically, refer to Figure 4 When the actual detected stress exceeds f n3 The duration t≥t n3 When the signal is displayed, it indicates that the actual pipeline stress detected has reached the shutdown response level. At this point, there is a risk of damage to the air conditioning pipeline. Continuing to operate the air conditioning equipment will cause huge losses. The key points of the target pipeline will be displayed in red, and the air conditioning equipment will be shut down.

[0097] When the number of shutdowns of the air conditioning unit exceeds the preset number n, an alarm signal is output for the unit. Back-end staff can then propose specific solutions to avoid affecting customer use of the air conditioning and reduce after-sales complaints. The air conditioning monitoring device 130 can monitor the stress state of every critical point in the piping of every outdoor unit 110 (each unit has a unique serial number) sold in real time. Based on the accumulation of data from long-term operation of the air conditioning units, it will dynamically update various thresholds, including the stress at each critical point in the piping. n1、 t n1、 f n2、 t n2、 f n3、 t n3、 ΔT 1、 ΔT 2、 ΔF 1、 ΔF 2、 ΔF 3、 ΔF 4、 The n-value ensures the normal operation and use of sold air conditioners, improves the reliability and durability of air conditioning piping, and reduces after-sales failures and customer complaints. Simultaneously, real-time feedback on detection stress, handling solutions, and implementation effects helps back-office staff adjust subsequent product design plans in a timely manner, providing reliable data support for improving product quality and development design.
