Description

Technical Field

[0001] The present application relates to the field of air conditioning supervision, and in particular to an air conditioning supervision method, device, air conditioning equipment and storage medium. Background Art

[0002] As the global climate warms and people's living standards improve, more and more families install and use air conditioners, and the use of air conditioners has increased dramatically. Usually, the use environment of the outdoor unit of the air conditioner is much worse than that of the indoor unit of the air conditioner. Changes in outdoor temperature differences, sunlight, air humidity and installation environment will have an indelible impact on the entire piping system of the outdoor unit of the air conditioner. Especially when the air conditioner is in operation, since the outdoor unit is usually installed outside the wall, it is difficult to detect abnormal conditions in the outdoor unit pipeline. The pipeline stress borne by various parts of the outdoor unit pipeline is constantly changing. When the stress continues to exceed the standard, it will cause the pipeline to deform and rupture, causing refrigerant leakage, which in turn affects the normal use of the air conditioner and people's life and property safety. In addition, the outdoor unit is usually installed outside the wall, and the cost and difficulty of repairing its after-sales failure are relatively high. Summary of the invention

[0048] Figure 1 FIG. 1 is an application environment diagram of an air conditioning monitoring method in an embodiment. Figure 1 The air conditioning monitoring method is applied to air conditioning equipment, the air conditioning equipment 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, the outdoor unit 110 and the indoor unit 120 are respectively connected to the air conditioning monitoring device 130 through a network, the outdoor unit 110 includes a pipeline system, refer to Figure 2 The pipeline system includes a plurality of pipeline key points, each of which is provided with a stress sensor, and the stress sensor is used to detect stress changes at the pipeline key points.

[0049] In one embodiment, Figure 2 FIG. 1 is a flow chart of an air conditioning monitoring method in an embodiment, referring to FIG. Figure 2 , provides an air conditioning monitoring method. This embodiment mainly applies this method to the above Figure 1 Taking the air conditioning monitoring device 130 in the example as an example, the air conditioning monitoring method specifically includes the following steps:

[0050] Step S210 , obtaining piping system parameters of the outdoor unit 110 in the air-conditioning device, wherein the piping system parameters include detection stresses of a plurality of piping key points in the piping system of the outdoor unit 110 .

[0051] Specifically, the pipeline key points are key points in the pipeline system that are determined based on tests to be prone to generate large stresses, and the detection stress of the pipeline key points is obtained through stress sensors arranged at the pipeline key points.

[0052] Step S220: determining the abnormal state of the external unit 110 according to the pipeline system parameters.

[0053] Specifically, whether the external unit 110 is in an abnormal state is determined based on the detected stress of each key point of the pipeline. Here, the detected stress of all key points of the pipeline can be combined to determine whether the external unit 110 is in an abnormal state, or the detected stress of a single key point of the pipeline can be used to determine whether the external unit 110 is in an abnormal state.

[0054] Step S230, controlling the operating parameters of the air-conditioning device according to the abnormal state of the outdoor unit 110, so as to restore the abnormal state of the outdoor unit 110 to a normal state.

[0055] Specifically, when it is determined that the outdoor unit 110 is 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 of each key point of the pipeline in the pipeline system, thereby restoring the abnormal state of the outdoor unit 110 to a normal state, thereby solving the problem that the prior art is unable to cope with the abnormal situation of the pipeline of the outdoor unit 110, and avoiding the deformation and rupture of the pipeline caused by the air-conditioning equipment continuing to operate according to the original operating mode without timely detecting the abnormality of the outdoor unit 110, thereby causing refrigerant leakage, avoiding affecting the normal use of the air conditioner and people's life and property safety, and can extend the service life of the air-conditioning equipment and improve the safety of the use of the air-conditioning equipment.

[0056] In one embodiment, determining the abnormal state of the external machine 110 according to the pipeline system parameters includes:

[0057] The abnormal state of the external unit 110 is determined according to 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, wherein the target pipeline key point is any pipeline key point in the pipeline system of the external unit 110.

[0058] Specifically, the detected stress of each key point of the pipeline is compared with the preset stress range corresponding to the key point of the pipeline, and the stress duration of the detected stress corresponding to the key point of the pipeline is compared with the corresponding preset duration range to determine whether the external unit 110 has abnormal overstress operation, that is, the abnormal state of the external unit 110 is accurately determined according to the detected stress of each key point of the pipeline and the stress duration of the detected stress. When the detected stress and the stress duration of the key point of the pipeline are different, the pipeline system of the external unit 110 is in different working states, and the working state is divided into normal and abnormal states with different abnormal levels. Therefore, the stress condition of the pipeline system of the air-conditioning equipment in different actual use scenarios can be detected in real time, and then the abnormal state of the external unit 110 can be discovered in time according to the stress condition of the pipeline system, so that the operating parameters of the air-conditioning equipment can be adjusted in time according to the abnormal state of the external unit 110, thereby eliminating the abnormal state of the external unit 110.

[0059] In one embodiment, referring to Figure 4 The determining of the abnormal state of the external unit 110 according to 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 detected stress is within the first stress range and the stress duration is within the first duration range, determining the first abnormal state as the abnormal state of the external machine 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 external machine 110, wherein the lower limit of the duration of the second duration range is greater than the upper limit of the duration 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 external machine 110, wherein the duration lower limit of the fourth duration range is greater than the duration upper limit of the third duration range;

[0063] When the target detected 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 external machine 110, wherein the abnormal level increases successively 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 is the first preset stress, f n2 is the second preset stress, the target detection stress is recorded as f, the stress duration is recorded as t, and 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 the actual detection stress exceeds f n1 If the duration of the abnormal state is not long, it is determined that the external unit 110 is in the first abnormal state.

[0065] The second stress range is [f n2 ,f n3 ), where f n3 is the third preset stress, the second duration range is greater than or equal to the first preset duration, and the third duration range is less than the second preset duration t n2 , in f n2 >f≥f n1 And t≥t n1 , or f n3 >f≥f n2 And t<t n2 When the actual detection stress exceeds f n1 The duration t≥tn1 , or the actual detected stress exceeds f n2 The duration of t<t n2 , indicating that the actually detected pipeline stress has reached the early 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. 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 the actual detection stress exceeds f n2 The duration t≥t n2 , indicating that the pipeline stress actually detected at this time has reached the rapid response level. At this time, the air conditioning pipeline stress has obviously exceeded the standard, and a more effective treatment plan is needed to prevent 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, in the range of f≥f n3 And t≥t n3 When the actual detection stress exceeds f n3 The duration t≥t n3 , indicating that the pipeline stress actually detected at this time has reached the shutdown response level. At this time, the air-conditioning pipeline here is already at risk of damage, and continuing to operate the air-conditioning equipment 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. The first abnormal state has the lowest abnormal level, and the fourth abnormal state has the highest abnormal level. Different response strategies are adopted for different abnormal levels. The corresponding relationship between the response strategy and the abnormal state is shown in Table 1 below:

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

[0070] Table 1

[0071] Referring to Table 1, it can be seen that the response strategy corresponding to the second abnormal state is early warning response, the response strategy corresponding to the third abnormal state is rapid response, and the response strategy corresponding to the fourth abnormal state is shutdown response. Different response strategies are adopted for graded response according to different abnormal states of the external unit 110 to quickly eliminate the abnormal state of the external unit 110, and corresponding display levels can also be output for different abnormal states, providing background staff with clearly visible display colors, so that the background staff can clearly grasp the stress conditions of each key point of the pipeline.

[0072] In one embodiment, controlling the operating parameters of the air-conditioning device according to the abnormal state of the external unit 110 includes:

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

[0074] Specifically, refer to Figure 4 When the abnormal state of the 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, but because 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, thereby avoiding abnormal correction in the first abnormal state and affecting the temperature control effect of the air-conditioning equipment.

[0075] In one embodiment, controlling the operating parameters of the air-conditioning device according to the abnormal state of the external unit 110 includes:

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

[0077] When the temperature difference is within a first temperature difference range, the compressor frequency of the air-conditioning device is controlled to switch from the current compressor frequency to the 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 controlled to switch 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 temperature difference of the first temperature difference range is greater than the upper limit of the temperature difference 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 temperature difference in the second temperature difference range is greater than the upper limit of the temperature difference in the third temperature difference range.

[0080] Specifically, refer to Figure 4 , when the abnormal state of the outdoor unit 110 is the second abnormal state, the early warning response is selected as the response strategy corresponding to the second abnormal state, and the abnormal correction method corresponding to the early warning response is based on the temperature difference ΔT between the indoor ambient temperature and the set temperature, and the adjustment frequency corresponding to the temperature difference range to which the temperature difference belongs is selected to be adjusted on the basis of the current compressor frequency, and the stress of the key points of the pipeline in the pipeline system of the outdoor unit 110 is changed by adjusting the compressor operating frequency, so as to avoid the detection stress of the key points of the pipeline being continuously maintained under high stress. The temperature difference ΔT is the absolute value of the difference between the indoor ambient temperature and the set temperature. When the air-conditioning equipment works in the cooling mode, ΔT = indoor ambient temperature - set temperature, and when the air-conditioning equipment works in the heating mode, ΔT = set temperature - indoor ambient temperature. The better the actual cooling and heating effect, the smaller ΔT, and the worse the actual cooling and heating effect, the larger ΔT.

[0081] When the first temperature difference range is greater than or equal to the first preset temperature difference ΔT1, that is, ΔT≥ΔT1, the first adjustment frequency ΔF1 is increased on the basis of 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. It is necessary to increase the compressor operating frequency to a large extent to increase the cooling capacity or heating capacity of the air-conditioning equipment, thereby reducing the gap between the indoor ambient temperature and the set temperature, that is, dynamically adjust the compressor operating frequency while optimizing the temperature control effect of the air-conditioning equipment, thereby avoiding the current compressor frequency corresponding to the large detection stress of the key points of the current pipeline, and avoiding the compressor operating frequency from continuously maintaining the current operating frequency, which will continuously increase the detection stress of the key points of the pipeline.

[0082] The second temperature difference range is [ΔT2, ΔT1), where ΔT2 is the second preset temperature difference. When ΔT1>ΔT≥ΔT2, the second adjustment frequency ΔF2 is added on the basis of the current compressor frequency F, that is, the second compressor frequency is F+ΔF2, where ΔT1>ΔT2, ΔF1>ΔF2. In this scenario, the temperature difference between the indoor ambient temperature and the set temperature is smaller than the temperature difference in the previous scenario. At this time, the indoor temperature control effect is better than the temperature control effect in the previous scenario. It is necessary to increase the compressor operating frequency to a smaller extent to increase the cooling capacity or heating capacity of the air-conditioning equipment, thereby further reducing the gap between the indoor ambient temperature and the set temperature. The compressor operating frequency is dynamically adjusted while optimizing the temperature control effect of the air-conditioning equipment, thereby avoiding the current compressor frequency corresponding to the larger detection stress of the key points of the current pipeline, and avoiding the compressor operating frequency from continuously maintaining the current operating frequency, which will continuously increase the detection stress of the key points of the pipeline.

[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, that is, 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 that the indoor temperature control effect is good. The compressor operating frequency can be reduced to a large extent to reduce the cooling capacity or heating capacity of the air-conditioning equipment, thereby saving the operating energy consumption of the compressor, and only playing a temperature maintenance effect on 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 larger detection stress of the key points of the current pipeline, and avoiding the compressor operating frequency from continuously maintaining the current operating frequency, which will continue to increase the detection stress of the key points of the pipeline.

[0084] In one embodiment, controlling the operating parameters of the air-conditioning device according to the abnormal state of the external unit 110 includes:

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

[0086] When the temperature difference is within the first temperature difference range, the compressor frequency of the air-conditioning equipment is controlled to switch 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 controlled to switch from the current compressor frequency to the 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 temperature difference in the first temperature difference range is greater than the upper limit of the temperature difference in 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 controlled to switch 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 temperature difference in the second temperature difference range is greater than the upper limit of the temperature difference in the third temperature difference range.

[0089] Specifically, refer to Figure 4 When the abnormal state of the outdoor unit 110 is the third abnormal state, a quick response is selected as the response strategy corresponding to the third abnormal state, and the abnormal correction method corresponding to the quick response is based on the temperature difference ΔT between the indoor ambient temperature and the set temperature, and the adjustment frequency corresponding to the temperature difference range to which the temperature difference belongs is selected to be adjusted on the basis of the current compressor frequency, and the stress of the key points of the pipeline in the pipeline system of the outdoor unit 110 is changed by adjusting the compressor operating frequency, so as to avoid the detection stress of the key points of the pipeline continuing to maintain a high stress state. However, the adjustment frequency corresponding to the quick response is greater than the adjustment frequency corresponding to the early warning response.

[0090] The third adjustment frequency is ΔF3, the fourth adjustment frequency is ΔF4, ΔF3>ΔF4>ΔF1>ΔF2. When ΔT≥ΔT1, the third adjustment frequency is added to the current compressor frequency to obtain the fourth compressor frequency, and the fourth compressor frequency is F+ΔF3. Since the detection stress under the third abnormal state is high, when the temperature difference between the indoor ambient temperature and the set temperature is the largest, that is, when the temperature control effect of the air-conditioning equipment is poor, it is necessary to increase the compressor operating frequency to the maximum extent to increase the cooling capacity or heating capacity of the air-conditioning equipment. Not only can the difference between the indoor ambient temperature and the set temperature be quickly reduced, but also the compressor operating frequency can be quickly switched from the current compressor frequency to the compressor frequency corresponding to other frequency bands, so as to quickly change the compressor operating frequency band with large detection stress, and dynamically adjust the compressor operating frequency while optimizing the temperature control effect of the air-conditioning equipment, so as to avoid the current compressor frequency corresponding to the large detection stress of the key point of the current pipeline, and avoid the compressor operating frequency from continuously maintaining the current operating frequency, which will continuously increase the detection stress of the key point of the pipeline.

[0091] When ΔT1>ΔT≥ΔT2, the temperature control effect in this scenario is better than that in the previous scenario, so the compressor adjustment frequency is less than the adjustment frequency in the previous scenario. The fourth adjustment frequency is added to the current compressor frequency to obtain the fifth compressor frequency, and the fifth compressor frequency is F+ΔF4. Since the detection stress in the third abnormal state is high, 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 large extent to reduce the temperature difference between the indoor ambient temperature and the set temperature, optimize the indoor temperature control effect, and increase the compressor operating frequency to a large extent to increase the cooling capacity or heating capacity of the air-conditioning equipment. Not only can the gap between the indoor ambient temperature and the set temperature be quickly reduced, but the compressor operating frequency can also be quickly switched from the current compressor frequency to the compressor frequency corresponding to other frequency bands, so as to quickly change the compressor operating frequency band with large detection stress, and dynamically adjust the compressor operating frequency while optimizing the temperature control effect of the air-conditioning equipment, so as to avoid the current compressor frequency corresponding to the large detection stress of the current key point of the pipeline, and avoid the compressor operating frequency continuously maintaining the current operating frequency, which will continuously increase the detection stress of the key point of the pipeline.

[0092] When ΔT<ΔT2, it indicates that the temperature control effect is good, and there is no need to continue to increase the cooling capacity or heating capacity. The third adjustment frequency is subtracted from the current compressor frequency F, that is, the sixth compressor frequency is F-ΔF3. In this scenario, the temperature difference between the indoor ambient temperature and the set temperature is small, indicating that the indoor temperature control effect is good, and the compressor operating frequency can be reduced to a large extent to reduce the cooling capacity or heating capacity of the air-conditioning equipment, thereby saving the operating energy consumption of the compressor, and only playing a temperature maintenance effect on the indoor ambient temperature, and the compressor operating frequency can be quickly switched from the current compressor frequency to the compressor frequency corresponding to other frequency bands, so as to quickly change the compressor operating frequency band with greater detection stress, and dynamically adjust the compressor operating frequency while ensuring the temperature control effect of the air-conditioning equipment, so as to avoid the current compressor frequency corresponding to the greater detection stress of the key points of the current pipeline, and avoid the compressor operating frequency continuing to maintain the current operating frequency, which will continue to increase the detection stress of the key points of the pipeline.

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

[0094] In one embodiment, controlling the operating parameters of the air-conditioning device according to the abnormal state of the external unit 110 includes:

[0095] When the abnormal state of the external unit 110 is the fourth abnormal state, the air conditioning device is controlled to shut down.

[0096] Specifically, refer to Figure 4 , when the actual detection stress exceeds f n3 The duration t≥t n3 , it means that the actual detected pipeline stress has reached the shutdown response level. At this time, the air-conditioning pipeline here is at risk of damage. 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 air-conditioning equipment shutdowns exceeds the preset number n, an alarm signal is output for the air-conditioning equipment, and the back-end staff can propose specific solutions in the back-end to avoid affecting the customer's use of the air-conditioning and reduce after-sales complaints. The air-conditioning monitoring device 130 can grasp the stress state of each key point of the pipeline of each air-conditioning outdoor unit 110 that has been sold (each is equipped with a unique factory number when leaving the factory) in real time. After accumulating data from the long-term operation of the after-sales air-conditioning, it will dynamically update various thresholds, including the f of each key point of the pipeline. n1、 t n1、 f n2、 t n2、 f n3、 t n3、 ΔT 1、 ΔT 2、 ΔF 1、 ΔF 2、 ΔF 3、 ΔF 4、 n value, ensuring the normal operation and use of sold air conditioners, improving the reliability and durability of air conditioner pipelines, and reducing after-sales failures and customer complaints. At the same time, real-time feedback of detection stress, treatment solutions and implementation effects can help back-end staff to adjust subsequent product design plans in a timely manner, providing reliable data support for improving product quality and development design.
