Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical side in the embodiment of the present inventionCase is clearly and completely described, and obviously, described embodiment is only one of the present inventionDivide embodiment, instead of whole embodiment. Based on the embodiment in the present invention, this area is generalLogical technical staff is not making the every other embodiment obtaining under creative work prerequisite,All belong to the scope of protection of the invention.
The embodiment of the present invention provides a kind of detection method of air-conditioning equipment, as shown in Figure 1, and bagDraw together:
101, obtain the operational factor of air-conditioning equipment.
Concrete, the operational factor of air-conditioning equipment can be divided into the history run parameter of air-conditioning equipmentAnd the current operational factor of air-conditioning equipment. Checkout equipment need to obtain the current operation of air-conditioning equipmentWhen parameter, can obtain by air-conditioning equipment the current operational factor of air-conditioning equipment. Be skyTune equipment, in running, can obtain each the current operational factor of self, by what obtainThe current operational factor of self is sent to checkout equipment.
The history run parameter of air-conditioning equipment can be stored in memory device, also can be stored in inspectionIn self memory space of measurement equipment. Like this, checkout equipment need to obtain air-conditioning equipmentWhen history run parameter, if the history run Parameter storage of air-conditioning equipment is in memory device,Checkout equipment obtains the history run parameter of air-conditioning equipment by this memory device. If air-conditioning equipmentHistory run Parameter storage in self memory space of checkout equipment, checkout equipment canTo get the history run parameter of this air-conditioning equipment from the memory space of himself.
Further, described operational factor comprises: the current running status of described air-conditioning equipment,Compressor operating frequency and/or indoor environment temperature and/or outdoor environment temperature and/Or indoor coil pipe and/or outdoor coil pipe used temperature, expansion valve opening and/or electrical heating are openedOff status.
It should be noted that, the current running status of air-conditioning equipment is that air-conditioning equipment is current residingRunning status, for example, the whether state in the protection of indoor coil anti-freeze or in chamberThe state of inner coil pipe overheat protector or the state in outdoor coil pipe used overheat protector or locateIn the state of compressor air-discharging overheat protector or the state in overcurrent protection or locateIn the state of IPM (IntelligentPowerModule, SPM) overheat protector,Or the state in modified tone rate protection or in other states.
Certainly, operational factor can also comprise the stable operation frequency dependence of other and air-conditioning equipmentParameter, for example, compressor exhaust temperature, compressor object run frequency, indoor fan turnSpeed, outdoor fan rotating speed, off-premises station voltage, current sample, air-conditioning selftest failure code, distantControl device sense temperature, compressor model etc., the present invention does not limit this.
It should be noted that, because the frequency of convertible frequency air-conditioner is according to load change, hereStable state is a kind of relative concept, and the stable operation frequency of air-conditioning equipment is air-conditioning equipment necessarilyIn time period, do not fluctuate or fluctuate and be less than the frequency values of the first threshold values. Wherein, the first threshold values canSet in advance.
102,, according to the operational factor of air-conditioning equipment, determine in air-conditioning equipment and whether exist performance to declineThe parts that subtract.
Wherein, checkout equipment is obtaining after the operational factor of air-conditioning equipment, can have two kinds of sidesMethod is determined the portion that whether has performance degradation in air-conditioning equipment according to the operational factor of this air-conditioning equipmentPart, specific as follows:
Checkout equipment can carry out the current operational factor of air-conditioning equipment and its history run parameterComparison, determines the parts that whether have performance degradation in air-conditioning equipment. Now, in step 101In, the operational factor that checkout equipment obtains air-conditioning equipment comprises: the current fortune of obtaining air-conditioning equipmentThe history run parameter of line parameter and air-conditioning equipment. Obtaining the history run parameter of air-conditioning equipmentTime, because air-conditioning equipment may be the new air-conditioning equipment of installing, not history run parameter,Be history run parameter for empty. So checkout equipment need to first be determined the air-conditioning equipment obtainingHistory run parameter be whether empty, in the time that checkout equipment is determined history run parameter non-NULL, canSo that the current operational factor of air-conditioning equipment and its history run parameter are compared, determine air-conditioningIn equipment, whether there are the parts of performance degradation. Be the operational factor according to air-conditioning equipment, reallyDetermine whether to exist the parts of performance degradation to comprise in air-conditioning equipment: at the history run of air-conditioning equipmentWhen parameter non-NULL, according to the history run ginseng of the current operational factor of air-conditioning equipment and air-conditioning equipmentNumber, determines the parts that whether have performance degradation in air-conditioning equipment.
That is to say, checkout equipment is established at the current operational factor and the air-conditioning that have obtained air-conditioning equipmentWhen standby history run parameter, when checkout equipment is determined the history run parameter non-NULL of air-conditioning equipment,While being air-conditioning equipment and not being the new air-conditioning equipment of installing, checkout equipment can be established according to air-conditioningThe current running status of the air-conditioning equipment in standby current operational factor, find running status withThe identical history run parameter of current running status of air-conditioning equipment, and then by this history run ginsengOther parameters in other parameters in number and the current operational factor of air-conditioning equipment are compared.If have in the current operational factor of air-conditioning equipment with respect to history run parameter and occur relatively large deviationParameter, is deviation and is not less than the second threshold values, now, can determine existence in air-conditioning equipmentThe parts that can decay.
If do not occur larger with respect to history run parameter in the current operational factor of air-conditioning equipmentThe parameter of deviation, is deviation and is all less than the second threshold values, now, can determine in air-conditioning equipmentThe parts that nonexistence can be decayed.
It should be noted that, the second threshold values in the embodiment of the present invention can set in advance.The second threshold values of different its correspondences of operational factor can be different.
Or in the time that checkout equipment is determined history run parameter for sky, checkout equipment also needs to obtainDefault standard operational factor. Now, checkout equipment is according to the operational factor of air-conditioning equipment, reallyDetermine whether to exist the parts of performance degradation to comprise in air-conditioning equipment: according to the current fortune of air-conditioning equipmentLine parameter and standard operational factor, determine the parts that whether have performance degradation in air-conditioning equipment.
That is to say, checkout equipment, in the time determining the history run parameter of obtaining for sky, is notThere is the history run parameter that gets this air-conditioning equipment, like this in order whether to detect this air-conditioning equipmentHave the parts of performance degradation, checkout equipment can further obtain default standard operational factor.Be, checkout equipment can working as according to the air-conditioning equipment in the current operational factor of air-conditioning equipmentFront running status, finds the standard that running status is identical with the current running status of air-conditioning equipmentOperational factor, and then by the current fortune of other parameters in this standard operational factor and air-conditioning equipmentOther parameters in line parameter are compared. If have in the current operational factor of air-conditioning equipment relativelyThere is the parameter of relatively large deviation in standard operational factor, be deviation and be not less than the second threshold values, thisTime, can determine the parts that have performance degradation in air-conditioning equipment.
If do not occur larger with respect to standard operational factor in the current operational factor of air-conditioning equipmentThe parameter of deviation, is deviation and is all less than the second threshold values, now, can determine in air-conditioning equipmentThe parts that nonexistence can be decayed.
It should be noted that, standard operational factor obtains according to experiment, can be stored in inspectionIn the memory space of measurement equipment, also can exist in memory device, the present invention does not limit this.
Or checkout equipment can be by the current operational factor of air-conditioning equipment and default standard fortuneLine parameter is compared, and determines the parts that whether have performance degradation in air-conditioning equipment. Now,In step 101, the operational factor that checkout equipment obtains air-conditioning equipment comprises: obtain air-conditioning and establishStandby current operational factor. And checkout equipment also needs the current operational factor according to air-conditioning equipmentIn the current running status of air-conditioning equipment, the current operation of obtaining running status and air-conditioning equipmentThe standard operational factor that state is identical, and then by other parameters in this standard operational factor and skyOther parameters in the current operational factor of tune equipment are compared. If the current fortune of air-conditioning equipmentIn line parameter, there is the parameter that occurs relatively large deviation with respect to standard operational factor, be deviation not littleIn the second threshold values, now, can determine the parts that have performance degradation in air-conditioning equipment.
If do not occur larger with respect to standard operational factor in the current operational factor of air-conditioning equipmentThe parameter of deviation, is deviation and is all less than the second threshold values, now, can determine in air-conditioning equipmentThe parts that nonexistence can be decayed.
It should be noted that, checkout equipment obtains the current operation shape of running status and air-conditioning equipmentThe method of the standard operational factor that state is identical can be that checkout equipment first obtains default standard operationParameter, is obtaining after the current operational factor of standard operational factor and air-conditioning equipment, and detection is establishedFor can, in the standard operational factor of obtaining, finding the current of running status and air-conditioning equipmentThe standard operational factor that running status is identical. Or checkout equipment is in storage standards operation ginsengIn the equipment of number, directly the current running status of air-conditioning equipment, finds running status and air-conditioningThe identical standard operational factor of current running status of equipment.
If 103 determine the parts that have performance degradation in air-conditioning equipment, by air-conditioning equipment neutralityThe dampening information of the parts that can decay is sent to user terminal.
Concrete, checkout equipment in the time determining the parts that have performance degradation in air-conditioning equipment,The dampening information of the parts of performance degradation can be sent to user terminal, pass through so that obtain userUser terminal is known the dampening information of the parts of air-conditioning equipment performance decay, thereby can be by skyThe comparatively serious parts of tune equipment performance decay are changed, and avoid air-conditioning equipment because of partsPerformance degradation and fault.
It should be noted that, user terminal is the terminal device that user uses, and can be wireless endEnd can be also catv terminal, and wireless terminal can be to point to user to provide voice and/or data to connectThe equipment of the general character, has the portable equipment of wireless connecting function or is connected to wireless-modulated solutionAdjust other treatment facilities of device. Wireless terminal can for example, through wireless access network (, RAN, RadioAccessNetwork) communicate with checkout equipment, wireless terminal can be mobile terminal,As mobile phone (or being called " honeycomb " phone) with there is the computer of mobile terminal, for example,Can be portable, pocket, hand-held, mobile device built-in computer or vehicle-mounted,They and wireless access network exchange language and/or data. For example, PCS (PCS,PersonalCommunicationService) phone, wireless phone, Session initiation Protocol(SIP) phone, WLL (WLL, WirelessLocalLoop) stand, individualThe equipment such as digital assistants (PDA, PersonalDigitalAssistant). Wireless terminal alsoCan be called system, subscriber unit (SubscriberUnit), subscriber station (SubscriberStation), movement station (MobileStation), travelling carriage (Mobile), distant station(RemoteStation), access point (AccessPoint), remote terminal (RemoteTerminal), access terminal (AccessTerminal), user terminal (UserTerminal),User agent (UserAgent), subscriber equipment (UserDevice) or subscriber's installation (UserEquipment)。
The embodiment of the present invention provides a kind of detection method of air-conditioning equipment, obtains air-conditioning equipmentOperational factor, determines whether existence of air-conditioning equipment according to the operational factor of the air-conditioning equipment obtainingThe parts that can decay, there are the parts of performance degradation in definite air-conditioning equipment time, can be by skyThe dampening information of the parts of tune equipment performance decay is sent to user terminal. Like this, with respect toPrior art is only in the time of air-conditioning equipment fault, and air-conditioning equipment is keeped in repair, can not be at skyWhen tune equipment does not have fault, the parts in air-conditioning equipment are detected, the present invention is at skyIn the maintenance process of tune equipment, checkout equipment can, by the operational factor of air-conditioning equipment, be determinedGo out the parts that whether have performance degradation in air-conditioning equipment, and by the decay letter of the parts of performance degradationBreath is sent to user terminal, so that user terminal determines whether these parts according to this dampening informationChange, reduced the aging of therefore parts, cause the possibility of air-conditioning equipment fault, fromAnd reduced the probability that air-conditioning equipment breaks down, strengthen the maintenance of air-conditioning equipment.
Further, as shown in Figure 2, before step 102, said method also comprises:
104, obtain the ambient parameter of air-conditioning equipment.
Concrete, determine in the operational factor of utilizing air-conditioning equipment whether air-conditioning equipment exists performanceWhen the parts of decay, may there is because the air quality in some region is very poor air-conditioning equipment fortuneAfter row a period of time, having there is serious dust stratification in the off-premises station of air-conditioning equipment, has stopped up air channel,Thereby hinder heat exchange, caused the operational effect variation of air-conditioning equipment, if now according to air-conditioningMay there is not some the parts of performance degradation, being mistaken for property in the operational factor of equipmentCan decay. In order to prevent that above-mentioned situation from occurring, checkout equipment can further obtain air-conditioning equipmentAmbient parameter. Now, checkout equipment can be at the environment of himself having stored this air-conditioning equipmentWhen parameter, can in its memory space, get the ambient parameter of this air-conditioning equipment. And in inspectionWhen measurement equipment is not stored the ambient parameter of this air-conditioning equipment, checkout equipment can be by user eventuallyEnd obtains the ambient parameter of air-conditioning equipment. Be, user can user terminal by air-conditioning equipmentAmbient parameter is sent to checkout equipment.
Further, checkout equipment is joined at the environment of the air-conditioning equipment that gets user terminal transmissionWhen number, the ambient parameter of air-conditioning equipment is stored in its memory space.
Further, the ambient parameter of above-mentioned air-conditioning equipment is the relevant of air-conditioning equipment place environmentParameter, mainly comprises: in the insulating power in room area, installation site, room, room extremelyFew one.
It should be noted that, the ambient parameter of air-conditioning equipment also can comprise other parameters, for example,Building age, construction quality etc., this does not limit this.
So, checkout equipment is obtaining after the ambient parameter of air-conditioning equipment, step 102According to the operational factor of air-conditioning equipment, determine the parts that whether have performance degradation in air-conditioning equipmentComprise: according to the ambient parameter of the operational factor of air-conditioning equipment and air-conditioning equipment, determine that air-conditioning establishesIn standby, whether there are the parts of performance degradation.
Concrete, checkout equipment is obtaining after the ambient parameter and operational factor of air-conditioning equipment,Checkout equipment is being determined its current operational factor and its history according to the operational factor of air-conditioning equipmentWhen relatively large deviation appears in operational factor or standard operational factor, checkout equipment can be according to its environmentParameter, in the region at this air-conditioning equipment place, determines its ambient parameter and air-conditioning equipment therewithThe identical contrast air-conditioning equipment of model whether there is the similar situation of air-conditioning equipment therewith, ifHave to be less than n contrast air-conditioning equipment and to occur the similar situation of air-conditioning equipment therewith, explanation isThe parts of air-conditioning equipment occur what performance degradation caused. Now, checkout equipment can further divideAnalyse the operational factor of air-conditioning equipment, and then determine the parts of performance degradation.
Or, if there be at least n contrast air-conditioning equipment all to occur that air-conditioning equipment is similar therewithSituation, may be because the external environment in this region causes, instead of the portion of air-conditioning equipmentThere is performance degradation in part. Now, checkout equipment can be according to n contrast air-conditioning equipment at least andThe operational factor of air-conditioning equipment is analyzed, and obtains possible reason, and then this is possible formerBecause being sent to user terminal. For example, may be that the air quality in this region is very poor, air-conditioning equipmentAfter operation a period of time, having there is serious dust stratification in its off-premises station, has stopped up air channel, therebyHindered heat exchange, caused the operational factor of air-conditioning equipment to occur relatively large deviation, checkout equipment canSo that above-mentioned possible reason is sent to user terminal, and checkout equipment can also be according to analysisThe possible reason going out, produces corresponding advisory information, and this advisory information is sent to userTerminal. Be, checkout equipment, according to the above-mentioned possible reason analyzing, produces outside purge chamberThe advisory information of machine, is sent to user terminal by this advisory information.
It should be noted that, n is greater than 1 integer, can set in advance.
It should be noted that, contrast air-conditioning equipment occurs that the similar situation of air-conditioning equipment is therewithRefer to that contrast air-conditioning equipment also has its current operational factor and history run parameter or standard operational factorThere is relatively large deviation, and the similar situation of deviation situation.
For example, air-conditioning equipment 1 is in the time that present mode of operation is a, and its operational factor b goes through with itOperational factor b ' in history operational factor occurs that deviation is c. And the contrast air-conditioning of air-conditioning equipment 1Equipment 2 in the time that its operational mode is a, the fortune in its operational factor b and its history run parameterLine parameter b ' occurs that deviation is d, and d and c can think identical in the scope of error operation,Now can think that the situation similar with air-conditioning equipment 1 appears in contrast air-conditioning equipment 2.
It should be noted that, deviation situation is similar refers to that deviation situation is in the scope of error operationCan think identical, the difference between deviation is less than the 3rd threshold values.
It should be noted that, the 3rd threshold values sets in advance. Deviation correspondence between different parametersThe 3rd threshold values can be different.
Further, said method, as shown in Figure 3, also comprises:
105, the dampening information of the parts of air-conditioning equipment performance decay is sent to clothes by checkout equipmentBusiness equipment.
Concrete, checkout equipment in the time detecting the parts that have performance degradation in air-conditioning equipment,In order to prevent that air-conditioning equipment, can be by air-conditioning because the parts of these performance degradations break downThe dampening information of the parts of equipment performance decay is sent to service equipment, to make attendantCan know by service equipment the dampening information of the parts of the performance degradation in air-conditioning equipment, fromAnd can make attendant according to dampening information, the parts of the performance degradation in air-conditioning equipment are enteredRow is analyzed, and makes its maintenance scheme, and then prevents that air-conditioning equipment from breaking down.
It should be noted that, service equipment is the equipment of the after-sales service of air-conditioning equipment. Service peopleMember can be known by this service equipment the ruuning situation of air-conditioning equipment.
Further, said method, shown in figure 3, also comprises:
106,, in the time of air-conditioning equipment fault, obtain the fault message that air-conditioning equipment sends.
Concrete, if air-conditioning equipment breaks down, air-conditioning equipment start or running in,Some abnormal variablees can be detected, now air-conditioning equipment can find according to abnormal variable that it is rightThe failure code of answering, these failure codes are exactly fault message, and now, air-conditioning equipment is determinedAfter fault message, this fault message is sent to checkout equipment.
It should be noted that, in air-conditioning equipment between pre-stored abnormal variable and failure codeCorresponding relation.
107, the fault message of air-conditioning equipment is sent to service equipment by checkout equipment.
Concrete, checkout equipment is receiving after the fault message that air-conditioning equipment sends, can be byThe fault message of air-conditioning equipment is sent to service equipment, to make attendant pass through service equipmentCan know the fault message of air-conditioning equipment, and then this air-conditioning equipment is keeped in repair accordingly.
It should be noted that, the present invention is to the order between step 101-105 and step 106-107Do not limit. Can first perform step 101-105, then perform step 106-107; Also can be firstExecution step 106-107, then perform step 101-105; Can also perform step 101-105 simultaneously,With step 106-107. In diagram, only express a kind of situation.
Exemplary, suppose that checkout equipment need to detect air-conditioning equipment 1 and whether occur performance degradationParts. If checkout equipment is by the history run parameter operational factor current with it of air-conditioning equipmentThe method of comparing is determined the parts that whether have performance degradation in air-conditioning equipment. Now, detectEquipment obtains the current operational factor of air-conditioning equipment 1 by air-conditioning equipment 1. In memory deviceObtain the history run parameter of air-conditioning equipment 1.
In the time that air-conditioning equipment 1 is not the new air-conditioning equipment of installing, the air-conditioning that checkout equipment obtains is establishedStandby 1 history run parameter non-NULL. Suppose the current fortune of the air-conditioning equipment 1 that checkout equipment obtainsLine parameter is: running status is refrigerating state, and the running frequency of compressor is a, indoor environmentTemperature is b, and indoor coil pipe is c, and outdoor coil pipe used temperature is d. The sky that checkout equipment obtainsThe history run parameter of tune equipment 1 is: running status is refrigerating state, and the operation of compressor frequentlyRate is a ', and indoor environment temperature is b ', and indoor coil pipe is c ', outdoor coil pipe used temperatureDegree is d '. Now, checkout equipment is by the current operational factor of air-conditioning equipment 1 and history run ginsengNumber is compared.
If checkout equipment is found in the current operational factor of air-conditioning equipment 1 in the process of comparisonRunning frequency and indoor environment temperature, all with history run parameter in running frequency and indoorEnvironment temperature there is relatively large deviation, be the operation in the current operational factor of air-conditioning equipment 1Frequency all with history run parameter in running frequency deviation be greater than the second threshold values. And air-conditioning equipment 1Current operational factor in indoor environment temperature all with history run parameter in indoor ringBorder temperature deviation is greater than the second threshold values.
Wherein, in the different parameters and history run parameter in the current operational factor of air-conditioning equipmentDifferent parameters between corresponding threshold value the second threshold values of deviation be different.
Now, checkout equipment is in order to determine whether more accurately it is the parts due to air-conditioning equipment 1The deviation of the above-mentioned parameter that occurs performance degradation and cause, checkout equipment can further obtain skyThe ambient parameter of tune equipment 1. The ambient parameter of supposing air-conditioning equipment 1 is that room area is f, roomBetween installation site be h. Checkout equipment is further determined in the region at air-conditioning equipment 1 place, with skyThe ambient parameter of tune equipment 1 is identical, and the contrast air-conditioning identical with the model of air-conditioning equipment 1 establishedFor 2, whether contrast air-conditioning equipment 3 and contrast air-conditioning equipment 4 occur with air-conditioning equipment 1 similarSituation. Be contrast air-conditioning equipment 2, whether contrast air-conditioning equipment 3 and contrast air-conditioning equipment 4Occur running frequency in current operational factor all with history run parameter in running frequency deviationBe greater than the second threshold values. And the indoor environment temperature in current operational factor is all joined with history runIndoor environment temperature deviation in number is greater than the second threshold values. If contrast air-conditioning equipment 2, contrast is emptyIn tune equipment 3 and contrast air-conditioning equipment 4, only there is contrast air-conditioning equipment 2 to occur and air-conditioning equipment 1Similar situation is not that 3 contrast air-conditioning equipments occur that air-conditioning equipment is similar therewithSituation, now, checkout equipment thinks that the parts of air-conditioning equipment 1 occur what performance degradation caused.Checkout equipment is according to the operational factor of air-conditioning equipment 1, thereby determines the parts of performance degradation.And the dampening information of these parts is sent to user terminal.
Or, if contrast air-conditioning equipment 2 is equal in contrast air-conditioning equipment 3 and contrast air-conditioning equipment 4Occurring the situation similar with air-conditioning equipment 1, is that air-conditioning therewith appears in 3 contrast air-conditioning equipmentsThe situation that equipment is similar, now, checkout equipment think air-conditioning equipment place region outsideBoundary's environment causes, instead of performance degradation appears in the parts of air-conditioning equipment 1. Now, detectEquipment can be according to air-conditioning equipment 1, contrast air-conditioning equipment 2, and contrast air-conditioning equipment 3 and contrast are emptyThe operational factor of tune equipment 4 is analyzed, and obtains possible reason, and possible reason is sent outDeliver to user terminal. Checkout equipment can also, according to the possible reason analyzing, produce correspondingAdvisory information, and this advisory information is sent to user terminal.
Or air-conditioning equipment 1 is the new air-conditioning equipment of installing, what now checkout equipment obtained goes throughHistory operational factor is empty, and being air-conditioning equipment 1 does not have history run parameter. Now, inspectionMeasurement equipment can obtain default standard operational factor, and the air-conditioning equipment 1 that checkout equipment is obtainedCurrent operational factor and standard operational factor compare, suppose the current fortune of air-conditioning equipment 1There is not the parameter of relatively large deviation in line parameter, now can think air-conditioning with standard operational factorIn equipment 1, there are not the parts of performance degradation, can send and not have performance to decline to user terminalSubtract the information of parts.
Further, in the time that checkout equipment detects air-conditioning equipment 1 and occurs the parts of performance degradation,The dampening information of these parts can be sent to service equipment simultaneously, so that attendant is according to thisInformation knows that decay appears in which parts, in the time that user need to change corresponding component, and can be directIt is changed.
Further, in the time that air-conditioning equipment 1 breaks down, air-conditioning equipment 1 can be determined eventBarrier information, and this fault message is sent to checkout equipment, now checkout equipment can be by receptionThe fault message of air-conditioning equipment 1 be sent to service equipment so that attendant is according to this faultInformation is known air-conditioning equipment 1 which unit failure, and then can directly carry out the parts of faultMaintenance.
