Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a detection method for an air conditioning device, as shown in fig. 1, including:
101. and acquiring the operating parameters of the air conditioning equipment.
Specifically, the operation parameters of the air conditioning equipment may be divided into historical operation parameters of the air conditioning equipment and current operation parameters of the air conditioning equipment. When the detection device needs to acquire the current operation parameters of the air conditioning device, the current operation parameters of the air conditioning device can be acquired through the air conditioning device. That is, the air conditioning equipment can obtain each current operation parameter of the air conditioning equipment during the operation process, and send the obtained current operation parameter of the air conditioning equipment to the detection equipment.
The historical operating parameters of the air conditioning system may be stored in the memory device or in the memory space of the detection device itself. In this way, when the detection device needs to acquire the historical operating parameters of the air conditioning device, if the historical operating parameters of the air conditioning device are stored in the storage device, the detection device acquires the historical operating parameters of the air conditioning device through the storage device. If the historical operating parameters of the air conditioning equipment are stored in the storage space of the detection equipment, the detection equipment can acquire the historical operating parameters of the air conditioning equipment from the storage space of the detection equipment.
Further, the operating parameters include: the current operating state of the air conditioning unit, the compressor operating frequency, and/or the indoor ambient temperature, and/or the outdoor ambient temperature, and/or the indoor coil temperature, and/or the outdoor coil temperature, the expansion valve opening, and/or the electrical heating switch state.
It should be noted that the current operation state of the air conditioning equipment is an operation state in which the air conditioning equipment is currently located, for example, whether the air conditioning equipment is in an indoor coil anti-freezing protection state, or in an indoor coil over-temperature protection state, or in an outdoor coil over-temperature protection state, or in a compressor exhaust over-temperature protection state, or in an over-current protection state, or in an IPM (intelligent power module) over-temperature protection state, or in a variable modulation rate protection state, or in another state.
Of course, the operation parameters may also include other parameters related to the stable operation frequency of the air conditioning equipment, such as the discharge temperature of the compressor, the target operation frequency of the compressor, the rotation speed of the indoor fan, the rotation speed of the outdoor fan, the voltage of the outdoor unit, the current sampling, the self-checking fault code of the air conditioner, the sensed temperature of the remote controller, the model number of the compressor, and the like, which is not limited in this respect.
It should be noted that, since the frequency of the inverter air conditioner varies according to the load, the steady state is only a relative concept, and the steady operation frequency of the air conditioner is a frequency value at which the air conditioner does not fluctuate or fluctuates less than the first threshold value within a certain period of time. Wherein the first threshold value may be preset.
102. And determining whether the performance attenuation component exists in the air conditioning equipment according to the operation parameter of the air conditioning equipment.
After the detection device obtains the operating parameters of the air conditioning device, there may be two methods for determining whether a performance-degraded component exists in the air conditioning device according to the operating parameters of the air conditioning device, which specifically include:
the detection device may compare the current operating parameters of the air conditioning device with historical operating parameters thereof to determine whether a performance degrading component is present in the air conditioning device. At this time, in step 101, the detecting device acquiring the operating parameter of the air conditioning device includes: and acquiring the current operating parameters of the air conditioning equipment and the historical operating parameters of the air conditioning equipment. When the historical operating parameters of the air conditioning equipment are obtained, the air conditioning equipment may be newly installed, and the historical operating parameters are not available, that is, the historical operating parameters are empty. Therefore, the detection device needs to determine whether the acquired historical operating parameter of the air conditioning device is empty, and when the detection device determines that the historical operating parameter is not empty, the current operating parameter of the air conditioning device can be compared with the historical operating parameter of the air conditioning device to determine whether a performance-degraded component exists in the air conditioning device. The component for determining whether performance attenuation exists in the air conditioning equipment according to the operation parameters of the air conditioning equipment comprises the following components: and when the historical operating parameters of the air-conditioning equipment are not empty, determining whether a performance attenuation component exists in the air-conditioning equipment or not according to the current operating parameters of the air-conditioning equipment and the historical operating parameters of the air-conditioning equipment.
That is to say, when the detection device obtains the current operating parameter of the air conditioning device and the historical operating parameter of the air conditioning device, and the detection device determines that the historical operating parameter of the air conditioning device is not empty, that is, when the air conditioning device is not a newly installed air conditioning device, the detection device may search the historical operating parameter, of which the operating state is the same as the current operating state of the air conditioning device, according to the current operating state of the air conditioning device in the current operating parameter of the air conditioning device, and then compare other parameters in the historical operating parameter with other parameters in the current operating parameter of the air conditioning device. If the current operation parameters of the air conditioning equipment include parameters with larger deviation relative to the historical operation parameters, namely the deviation is not smaller than the second threshold value, at this time, components with performance attenuation in the air conditioning equipment can be determined.
If the current operating parameters of the air conditioning equipment do not have parameters with larger deviations relative to the historical operating parameters, namely the deviations are smaller than the second threshold, at this time, it can be determined that no performance-attenuated components exist in the air conditioning equipment.
It should be noted that the second threshold value in the embodiment of the present invention may be preset. The second threshold value may be different for different operating parameters.
Or, when the detection device determines that the historical operating parameter is empty, the detection device needs to obtain a preset standard operating parameter. At this time, the detecting device determines whether there is a performance degradation in the air conditioner according to the operation parameter of the air conditioner, including: and determining whether the performance attenuation part exists in the air conditioning equipment or not according to the current operating parameter and the standard operating parameter of the air conditioning equipment.
That is to say, the detection device determines that the acquired historical operating parameter is empty, that is, the historical operating parameter of the air conditioning device is not acquired, so that the detection device may further acquire a preset standard operating parameter in order to detect whether a performance-degraded component exists in the air conditioning device. That is, the detection device may find the standard operating parameter whose operating state is the same as the current operating state of the air conditioning device according to the current operating state of the air conditioning device in the current operating parameters of the air conditioning device, and then compare the other parameters in the standard operating parameter with the other parameters in the current operating parameters of the air conditioning device. If the current operating parameters of the air-conditioning equipment include parameters with larger deviation relative to the standard operating parameters, namely the deviation is not smaller than the second threshold value, at this time, components with performance attenuation in the air-conditioning equipment can be determined.
If the current operating parameters of the air conditioning equipment do not have parameters with larger deviations relative to the standard operating parameters, namely the deviations are smaller than the second threshold value, at this time, it can be determined that no performance-attenuated component exists in the air conditioning equipment.
It should be noted that the standard operating parameters are obtained through experiments, and may be stored in a storage space of the detection device, or may be stored in a storage device, which is not limited in the present invention.
Or, the detection device may compare the current operating parameter of the air conditioning device with a preset standard operating parameter, and determine whether a performance-degraded component exists in the air conditioning device. At this time, in step 101, the detecting device acquiring the operating parameter of the air conditioning device includes: and acquiring the current operating parameters of the air conditioning equipment. And the detection device also needs to acquire a standard operation parameter with the same operation state as the current operation state of the air conditioning device according to the current operation state of the air conditioning device in the current operation parameters of the air conditioning device, and then compare other parameters in the standard operation parameter with other parameters in the current operation parameters of the air conditioning device. If the current operating parameters of the air-conditioning equipment include parameters with larger deviation relative to the standard operating parameters, namely the deviation is not smaller than the second threshold value, at this time, components with performance attenuation in the air-conditioning equipment can be determined.
If the current operating parameters of the air conditioning equipment do not have parameters with larger deviations relative to the standard operating parameters, namely the deviations are smaller than the second threshold value, at this time, it can be determined that no performance-attenuated component exists in the air conditioning equipment.
It should be noted that, the method for the detection device to obtain the standard operation parameter with the operation state the same as the current operation state of the air conditioning device may be that the detection device first obtains a preset standard operation parameter, and after obtaining the standard operation parameter and the current operation parameter of the air conditioning device, the detection device may find the standard operation parameter with the operation state the same as the current operation state of the air conditioning device from the obtained standard operation parameter. Or, the detection device directly detects the current operating state of the air conditioning device in the device for storing the standard operating parameters, and finds the standard operating parameters with the operating state the same as the current operating state of the air conditioning device.
103. And if the fact that the performance attenuation components exist in the air conditioning equipment is determined, attenuation information of the performance attenuation components in the air conditioning equipment is sent to the user terminal.
Specifically, when the detection device determines that the performance-attenuated component exists in the air-conditioning equipment, the attenuation information of the performance-attenuated component can be sent to the user terminal, so that the user can know the attenuation information of the performance-attenuated component in the air-conditioning equipment through the user terminal, the component with the serious performance attenuation in the air-conditioning equipment can be replaced, and the failure of the air-conditioning equipment due to the performance attenuation of the component is avoided.
It should be noted that the user terminal is a terminal device used by the user, and may be a wireless terminal or a wired terminal, and the wireless terminal may be a device providing voice and/or data connectivity to the user, a handheld device having a wireless connection function, or other processing device connected to a wireless modem. The wireless terminal, which may be a mobile terminal such as a mobile phone (or so-called "cellular" phone) and a computer having a mobile terminal, e.g., a portable, pocket, hand-held, computer-included or vehicle-mounted mobile device, may communicate with the detection apparatus via a radio access network (e.g., RAN). Such as Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and the like. A wireless terminal may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a Mobile station (MobileStation), a Mobile station (Mobile), a remote station (RemoteStation), an access point (AccessPoint), a remote terminal (remoterterminal), an access terminal (AccessTerminal), a user terminal (UserTerminal), a user agent (useeragent), a user equipment (UserDevice), or a user equipment (userreequipment).
The embodiment of the invention provides a detection method of air conditioning equipment, which comprises the steps of obtaining operating parameters of the air conditioning equipment, determining whether the air conditioning equipment has a performance attenuation component or not according to the obtained operating parameters of the air conditioning equipment, and sending attenuation information of the performance attenuation component in the air conditioning equipment to a user terminal when determining that the performance attenuation component exists in the air conditioning equipment. Therefore, compared with the prior art that the air conditioning equipment is only maintained when the air conditioning equipment fails, and the components in the air conditioning equipment cannot be detected when the air conditioning equipment does not fail, the detection equipment can determine whether the components with attenuated performance exist in the air conditioning equipment or not through the operation parameters of the air conditioning equipment in the maintenance process of the air conditioning equipment, and sends the attenuation information of the components with attenuated performance to the user terminal, so that the user terminal can determine whether the components are replaced or not according to the attenuation information, the possibility of the air conditioning equipment failure caused by aging of the components is reduced, the probability of the air conditioning equipment failure is reduced, and the maintenance of the air conditioning equipment is enhanced.
Further, as shown in fig. 2, before step 102, the method further includes:
104. and acquiring environmental parameters of the air conditioning equipment.
Specifically, when determining whether the air conditioning equipment has performance-degraded components by using the operating parameters of the air conditioning equipment, there may be a case where the air quality of some areas is poor, and after the air conditioning equipment operates for a period of time, an outdoor unit of the air conditioning equipment generates severe dust deposition to block an air duct, thereby hindering heat exchange and causing a deterioration in the operating effect of the air conditioning equipment, and at this time, if some components which do not have performance degradation may be erroneously determined as performance degradation according to the operating parameters of the air conditioning equipment. In order to prevent this, the detection device may further acquire an environmental parameter of the air conditioning device. At this time, the detection device may obtain the environmental parameter of the air conditioning device in its storage space when it stores the environmental parameter of the air conditioning device itself. And when the detection equipment does not store the environmental parameters of the air conditioning equipment, the detection equipment can acquire the environmental parameters of the air conditioning equipment through the user terminal. That is, the user may send the environmental parameter of the air conditioning device to the detection device through the user terminal.
Further, when the detection device obtains the environmental parameters of the air conditioning device sent by the user terminal, the detection device stores the environmental parameters of the air conditioning device into the storage space of the detection device.
Further, the environmental parameters of the air conditioning equipment are related parameters of the environment where the air conditioning equipment is located, and mainly include: at least one of room area, room installation location, and heat preservation capability of the room.
It should be noted that the environmental parameters of the air conditioning equipment may also include other parameters, such as the age of the building, the quality of the building, etc., which should not be limited herein.
Thus, after the detecting device obtains the environmental parameter of the air conditioning device, step 102 determines whether there is performance degradation in the air conditioning device according to the operating parameter of the air conditioning device, including: and determining whether the performance attenuation part exists in the air conditioning equipment or not according to the operating parameters of the air conditioning equipment and the environmental parameters of the air conditioning equipment.
Specifically, after the detection device acquires the environmental parameters and the operating parameters of the air-conditioning device, when the detection device determines that the current operating parameters of the air-conditioning device have a large deviation from the historical operating parameters or the standard operating parameters according to the operating parameters of the air-conditioning device, the detection device may determine, according to the environmental parameters, whether a comparison air-conditioning device having the same environmental parameters and the same model of the air-conditioning device is similar to the air-conditioning device in an area where the air-conditioning device is located, and if there are fewer than n comparison air-conditioning devices having the same model as the air-conditioning device, it is indicated that performance degradation occurs in a component of the air-conditioning device. At this time, the detection device may further analyze the operating parameters of the air conditioning device to determine the performance-degraded component.
Alternatively, if at least n of the comparative air conditioners are similar to the air conditioner, performance degradation may occur due to the external environment of the area, rather than the components of the air conditioner. At this time, the detection device may analyze the at least n comparison air-conditioning devices and the operation parameters of the air-conditioning devices to obtain a possible reason, and then send the possible reason to the user terminal. For example, it may be that the air quality in the area is poor, after the air conditioning equipment operates for a period of time, the outdoor unit of the air conditioning equipment generates serious dust deposition to block the air duct, thereby hindering heat exchange and causing a large deviation of the operating parameters of the air conditioning equipment, the detection equipment may send the possible reasons to the user terminal, and the detection equipment may further generate corresponding advice information according to the analyzed possible reasons and send the advice information to the user terminal. That is, the detection device generates advice information for cleaning the outdoor unit according to the analyzed possible reasons, and sends the advice information to the user terminal.
N is an integer greater than 1, and may be set in advance.
It should be noted that the case that the comparison air conditioner is similar to the air conditioner means that the comparison air conditioner has a situation that the current operation parameter of the comparison air conditioner is greatly deviated from the historical operation parameter or the standard operation parameter, and the deviation case is similar.
For example, when the current operation mode is a, the deviation of the operation parameter b of the air conditioner 1 from the operation parameter b' in the historical operation parameters is c. When the operation mode of the comparative air-conditioning equipment 2 of the air-conditioning equipment 1 is a, the deviation between the operation parameter b and the operation parameter b' in the historical operation parameters is d, and d and c can be considered to be the same in the error operation range, at this time, the comparative air-conditioning equipment 2 can be considered to have the similar situation with the air-conditioning equipment 1.
It should be noted that the deviation conditions are similar, which means that the deviation conditions can be considered as the same within the error operation range, and the difference value between the deviations is smaller than the third threshold value.
Note that the third threshold is preset. The third threshold may be different for deviations between different parameters.
Further, as shown in fig. 3, the method further includes:
105. the detection device transmits attenuation information of the components with attenuated performance in the air conditioning device to the service device.
Specifically, when the detection device detects that the air conditioning device has the performance-degraded components, in order to prevent the air conditioning device from being out of order due to the performance-degraded components, attenuation information of the performance-degraded components in the air conditioning device can be sent to the service device, so that the service personnel can obtain the attenuation information of the performance-degraded components in the air conditioning device through the service device, and therefore the service personnel can analyze the performance-degraded components in the air conditioning device according to the attenuation information, make a maintenance scheme of the components, and further prevent the air conditioning device from being out of order.
The service equipment is after-sales maintenance equipment for air conditioning equipment. The service personnel can know the operation condition of the air conditioning equipment through the service equipment.
Further, the method, as shown in fig. 3, further includes:
106. and when the air conditioning equipment fails, acquiring fault information sent by the air conditioning equipment.
Specifically, if the air conditioning equipment fails, the air conditioning equipment detects some abnormal variables in the starting or running process, the air conditioning equipment can search the corresponding fault codes according to the abnormal variables, the fault codes are fault information, and at the moment, the air conditioning equipment sends the fault information to the detection equipment after determining the fault information.
The air conditioner stores in advance a correspondence relationship between an abnormal variable and a fault code.
107. The detection equipment sends the fault information of the air conditioning equipment to the service equipment.
Specifically, after receiving the fault information sent by the air conditioning equipment, the detection equipment can send the fault information of the air conditioning equipment to the service equipment, so that service personnel can know the fault information of the air conditioning equipment through the service equipment, and further perform corresponding maintenance on the air conditioning equipment.
It should be noted that the sequence between steps 101-105 and steps 106-107 is not limited in the present invention. Step 101-; step 106-; step 101-. Only one case is shown in the figure.
For example, it is assumed that the detection device needs a component that detects whether the performance degradation of the air-conditioning apparatus 1 occurs. And if the detection equipment determines whether the air conditioning equipment has a performance attenuation part by a method of comparing the historical operating parameters of the air conditioning equipment with the current operating parameters of the air conditioning equipment. At this time, the detection device acquires the current operation parameters of the air conditioner 1 through the air conditioner 1. The historical operating parameters of the air conditioning system 1 are acquired in a memory device.
When the air conditioner 1 is not a newly installed air conditioner, the historical operating parameters of the air conditioner 1 acquired by the detection device are not null. Assume that the current operating parameters of the air conditioning equipment 1 acquired by the detection equipment are: the running state is a refrigeration state, the running frequency of the compressor is a, the indoor environment temperature is b, the indoor coil temperature is c, and the outdoor coil temperature is d. The historical operating parameters of the air conditioning equipment 1 acquired by the detection equipment are as follows: the operation state is a refrigeration state, the operation frequency of the compressor is a ', the indoor environment temperature is b', the indoor coil temperature is c ', and the outdoor coil temperature is d'. At this time, the detection device compares the current operation parameter of the air conditioning device 1 with the historical operation parameter.
If the detection device finds that the operating frequency and the indoor ambient temperature in the current operating parameters of the air conditioning device 1 are greatly deviated from the operating frequency and the indoor ambient temperature in the historical operating parameters in the comparison process, that is, the deviation between the operating frequency in the current operating parameters of the air conditioning device 1 and the operating frequency in the historical operating parameters is larger than a second threshold value. And the deviation between the indoor ambient temperature in the current operation parameters of the air conditioning equipment 1 and the indoor ambient temperature in the historical operation parameters is larger than a second threshold value.
And the second threshold values corresponding to the deviations between different parameters in the current operation parameters of the air conditioning equipment and different parameters in the historical operation parameters are different.
At this time, the detection device may further acquire the environmental parameters of the air-conditioning apparatus 1 in order to more accurately determine whether the deviation of the above parameters is caused by the occurrence of performance degradation of the components of the air-conditioning apparatus 1. Let the environmental parameter of the air conditioner 1 be the room area f and the room installation position be h. The detection device further determines whether a similar situation to the air conditioner 1 occurs in the comparison air conditioner 2, the comparison air conditioner 3 and the comparison air conditioner 4, which have the same environmental parameters as the air conditioner 1 and the same model as the air conditioner 1, in the area where the air conditioner 1 is located. That is, comparing the air conditioner 2, comparing whether the operating frequency in the current operating parameter and the operating frequency in the historical operating parameter of the air conditioner 3 and the air conditioner 4 are different by more than a second threshold. And the deviation between the indoor ambient temperature in the current operation parameters and the indoor ambient temperature in the historical operation parameters is larger than a second threshold value. If the air conditioner 2 is compared, only the comparative air conditioner 2 in the comparative air conditioner 3 and the comparative air conditioner 4 is similar to the air conditioner 1, but not the 3 comparative air conditioners are similar to the air conditioner, and at this time, the detection device is considered to be caused by performance degradation of the components of the air conditioner 1. The detection device determines the performance-degrading components from the operating parameters of the air conditioning unit 1. And transmits the attenuation information of this component to the user terminal.
Or, if the air-conditioning apparatus 2 is compared, the conditions similar to the air-conditioning apparatus 1 occur in both the air-conditioning apparatus 3 and the air-conditioning apparatus 4, and the conditions similar to the air-conditioning apparatus occur in 3 of the comparison air-conditioning apparatuses, at this time, the detection apparatus is considered to be caused by the external environment of the area where the air-conditioning apparatus is located, but the performance of the components of the air-conditioning apparatus 1 is not degraded. At this time, the detection device may analyze the operation parameters of the air-conditioning device 1, the comparison air-conditioning device 2, the comparison air-conditioning device 3, and the comparison air-conditioning device 4, obtain a possible reason, and send the possible reason to the user terminal. The detection device can also generate corresponding suggestion information according to the analyzed possible reasons, and send the suggestion information to the user terminal.
Or, the air conditioner 1 is a newly installed air conditioner, and the historical operating parameter acquired by the detection device is empty at this time, that is, the air conditioner 1 does not have the historical operating parameter. At this time, the detection device may obtain a preset standard operation parameter, and compare the current operation parameter of the air conditioning device 1 obtained by the detection device with the standard operation parameter, and assuming that the current operation parameter of the air conditioning device 1 does not have a parameter having a large deviation from the standard operation parameter, it may be considered that no component having performance attenuation occurs in the air conditioning device 1, and information that no component having performance attenuation occurs may be sent to the user terminal.
Furthermore, when the detection device detects that the air conditioning device 1 has a component with performance attenuation, the attenuation information of the component can be simultaneously sent to the service device, so that the service personnel can know which components have attenuation according to the information, and when the user needs to replace the corresponding component, the component can be directly replaced.
Further, when the air conditioner 1 breaks down, the air conditioner 1 can determine fault information and send the fault information to the detection device, and the detection device can send the received fault information of the air conditioner 1 to the service device, so that the service personnel can know which parts of the air conditioner 1 are broken down according to the fault information, and then the parts which break down can be directly maintained.
The embodiment of the invention provides a detection method of air conditioning equipment, which comprises the steps of obtaining operating parameters of the air conditioning equipment, determining whether the air conditioning equipment has a performance attenuation component or not according to the obtained operating parameters of the air conditioning equipment, and sending attenuation information of the performance attenuation component in the air conditioning equipment to a user terminal when determining that the performance attenuation component exists in the air conditioning equipment. Therefore, compared with the prior art that the air conditioning equipment is only maintained when the air conditioning equipment fails, and the components in the air conditioning equipment cannot be detected when the air conditioning equipment does not fail, the detection equipment can determine whether the components with attenuated performance exist in the air conditioning equipment or not through the operation parameters of the air conditioning equipment in the maintenance process of the air conditioning equipment, and sends the attenuation information of the components with attenuated performance to the user terminal, so that the user terminal can determine whether the components are replaced or not according to the attenuation information, the possibility of the air conditioning equipment failure caused by aging of the components is reduced, the probability of the air conditioning equipment failure is reduced, and the maintenance of the air conditioning equipment is enhanced.
In addition, in the prior art, after the components of the air conditioning equipment are attenuated, the components cannot be detected in time, so that the refrigerating or heating capacity of the air conditioning equipment is weakened, and if the expected refrigerating or heating effect is achieved, the consumed electric quantity needs to be greatly increased, and the energy conservation and the environmental protection are not facilitated. The detection device can determine whether the air conditioning equipment has the performance-attenuated components or not, and sends the attenuation information of the performance-attenuated components to the user terminal, so that the performance-attenuated components can be replaced by a user corresponding to the user terminal, the possibility of increasing the electric quantity consumption is reduced, and the energy conservation and environmental protection are facilitated.
