[0001] 本申请要求2007年5月四日提交的巴西专利NO.PI702369-3的优先权,在此引入其公开的内容作为参考。 [0001] This application claims the Brazilian patent on May 4, 2007 filed NO.PI702369-3, the disclosures are incorporated herein by reference.

技术领域 FIELD

[0002] 本申请涉及一种诊断系统和方法,可使得家用电器、制冷系统和/或其组件的操作状况可被即时或稍后看到。 [0002] The present application relates to a diagnostic system and method may be such that the home appliance, the refrigeration system and / or operating conditions of assembly may be seen immediately or later. 本发明进一步涉及一种由本发明的诊断系统和方法诊断的压缩机。 The present invention further relates to a method of diagnosing a compressor by a diagnostic system and method of the present invention.

背景技术 Background technique

[0003] 制冷系统通常已被大多数人们熟知。 [0003] Refrigeration systems typically most people are well known. 因此,由于许多情况下这些系统为人们所需要,开发可操纵、控制或诊断它们操作的方法是有意义的。 Therefore, since in many cases these systems is that people need to develop manipulate, control or diagnostic methods they operate is significant. 但是,在提到一些控制制冷系统的方法的种类之前,需要描述制冷系统的典型的现有技术的例子及其应用。 However, in the previously mentioned type of methods of controlling a refrigeration system, and its application we need to describe examples of typical prior art refrigeration system.

[0004] 典型地,制冷系统包括回路,冷却流体在其中行进穿过一些组件,在行进期间流体的体积被膨胀和压缩,而其温度和压力也上升和下降。 [0004] Typically, the refrigeration system comprises a loop, in which the cooling fluid travels through some of the components, during travel of the fluid volume is expanded and compressed, while its temperature and pressure rise and fall. 当涉及流体时,观察上述量值之间的紧密关系是重要的。 When it comes to fluid, observe the close relationship between the magnitude is important.

[0005] 形成普通制冷系统的组件例如为:压缩机、蒸发器、冷凝器和毛细管。 [0005] The assembly is formed, for example normal cooling systems: a compressor, an evaporator, a condenser and a capillary tube. 压缩机正如其名所指,压缩冷却流体,增大其压力及其温度,使得流体被抽吸并推动在冷却回路中流动。 As its name indicated compressor, cooling the compressed fluid, increasing its pressure and its temperature, so that fluid is sucked and pushed to flow in the cooling circuit.

[0006] 离开压缩机后,冷却流体循环通过负责降低流体温度而不降低其压力的冷凝器。 [0006] After leaving the compressor, the cooling fluid is responsible for reducing the temperature of the fluid circulated through the condenser without reducing its pressure. 冷凝器通常为长导管,该长导管布置成具有在端部通过蜿蜒或弯曲部分相互连接的直线平行部分,形状大致为“S”形。 Condenser duct is generally long, the elongated conduit having an end portion arranged to be parallel to the linear portion by a serpentine or curved portions interconnected to form a substantially "S" shape. 因此,由于该冷凝器与环境接触,当冷却流体在冷凝器中循环时将热散发至环境,其温度得以降低。 Accordingly, since the condenser in contact with the environment, when the cooling fluid circulating in the condenser to dissipate heat to the environment, the temperature is reduced.

[0007] 冷却流体从冷凝器流向毛细管,也称为膨胀阀,其功能在于形成对流体通过的阻力,因此导致在冷凝器中的流体和在下一组件中的流体之间的大压力差,下一组件为蒸发器,其中压力低。 [0007] The cooling fluid flows from the condenser capillary, also referred to as an expansion valve, the function of which is formed by the resistance to flow, thus resulting in a large pressure difference between the fluid and the fluid in the condenser of the next component in the difference, under a component of an evaporator, where the pressure is low. 因此,由于蒸发器中的低压和毛细管中的高压、高流体阻力之间的差,冷却流体在其流向蒸发器时经历突变,其体积突然膨胀并被插入至低压环境中。 Accordingly, since the difference between the high pressure, high fluid resistance in the low-pressure evaporator and the capillary, the cooling fluid as it undergoes mutation to the evaporator, the volume of which is suddenly expanded and inserted into a low pressure environment. 因此,考虑到温度、压力和体积量值之间的紧密关系,可总结出:如果体积增大且压力降低,冷却流体的温度也降低,有益于吸收与所述蒸发器接触的环境热量。 Thus, considering the close relationship between the temperature, pressure and volume values, can be summed up: If the volume increases and the pressure decreases, the temperature of the cooling fluid is reduced, the absorption of ambient heat conducive contact with the evaporator.

[0008] 最后,处于这种膨胀体积、低压和低温状况的冷却流体从蒸发器流向压缩机,在压缩机中其体积被减小而其压力和温度增加,重新开始制冷循环。 [0008] Finally, this expansion in volume, lower pressure and temperature conditions of the evaporator cooling fluid flows from the compressor, the volume of which is reduced in the compressor and increasing its pressure and temperature, refrigeration cycle starts anew.

[0009] 以上示例的典型系统可用在家用冰箱、空调、商用冰箱、产品展示冰柜以及任何需要被制冷或具有制冷功能的装置中。 [0009] A typical example of the above system can be used in household refrigerators, air conditioners, commercial refrigerators, freezers and Products to be any device having a refrigeration or cooling function.

[0010] 现已描述制冷系统,我们回到怎样控制、诊断或操纵其操作的问题上来。 [0010] Having now described the refrigeration system back to how we control, diagnose problems or manipulate its operation up. 在这点上,需要指出的是现有技术确实已有一种控制制冷和制热系统中温度的系统和方法,但是并未提供一种诊断故障并因此阻止可在该系统中发生的重大故障的系统或方法。 In this regard, it should be noted that the prior art does have a system and method for cooling and heating in the temperature control system, but does not provide a major failure and thus prevent a diagnostic fault may occur in the system system or method. [0011] 因此,对于制冷系统的诊断,可公正地说,为了所述系统适当地工作,制冷系统及其组件(风扇、抗解冻装置、切断阀、压缩机等等)需要不同的稳固性特性。 [0011] Thus, the diagnosis of the refrigeration system, may be fair to say that, for the system to work properly, the refrigeration system and its components (fans, anti-thawing device, shut-off valves, compressors, etc.) require different stability characteristics . 但是,这些特性可依据制冷系统所处的环境而变,考虑到每个环境都具有随时间而变的特定特性,例如:湿度、灰尘和通风。 However, these characteristics may vary according to the environment in which the cooling system, taking into account the specific characteristics of each environment has changed over time, for example: humidity, dust and ventilation. 此外,其他因素可改变组件的稳固性特性,包括使用条件、磨损和组件老化。 In addition, other factors that can change the stability characteristics of the assembly, including the conditions of use, wear and aging of components. 即,在使用寿命范围内,组件和任何物理装置由于环境或使用条件而均经受磨损和工作能力的改变。 That is, in the range of life, and any physical apparatus components due to environmental or use conditions are subject to change wear and ability to work.

[0012] 因此,使用条件、磨损和组件老化可引发这些装置的故障,其反映在制冷系统的效率上。 [0012] Thus, the conditions of use, wear and aging of components can cause failure of these devices, which is reflected in the efficiency of the refrigeration system. 这些故障可被分为两组:(i)完全失效;以及(ii)轻微偏差。 These faults can be divided into two groups: (i) complete failure; and (ii) a slight deviation.

[0013] 在完全失效情况下,系统的有缺陷元件可表现为不规则或间歇操作或者可完全无效,危害整个制冷循环。 There [0013] In the case of a complete failure, the system may be defective element showed irregular or intermittent operation or may be completely ineffective, endangering the whole refrigeration cycle. 因此,该量值的故障可带来巨大损失,首先是由于典型制冷回路的元件串联布置,即一个有缺陷装置可使得系统运作瘫痪。 Thus, the magnitude of the fault may be a huge loss, primarily because the typical components of the refrigeration circuit arranged in series, i.e., such a defective device may paralyze the system.

[0014] 其次,由于系统具有很大的时间常数而使用者可在长时间过去后仅注意到制冷循环中的偏差,由该种故障发生而导致的损失在一些情况下是由于故障识别的缓慢过程。 [0014] Second, since the system has a large time constant can be noted that the user in the refrigeration cycle deviation only after a long time past, this type of failure by a loss caused due to the slow fault identification in some cases process. 在此情况下,当缺陷未被检测出时,即使系统仍在工作,该系统将不再正常操作且将使组件过载,大大降低它们的使用寿命。 In this case, when the defect is not detected, even if the system is still working, the system will not operate properly and will overload assembly, greatly reduce their useful life. 在许多情况下,由损坏制冷负载导致的损失可超过维护制冷系统的成本。 In many cases, the loss caused by damage to the cooling load can exceed the cost of maintenance of the refrigeration system.

[0015] 另一方面,由于故障容易被误认为是由环境温度和/或热负载改变导致的系统能够出现的变化,因此当操作中存在轻微偏差时,识别有缺陷元件的过程甚至更慢和更困难。 [0015] On the other hand, due to a failure easily be mistaken for system changes in ambient temperature and / or thermal load can occur due to the change, so that when there is a slight deviation in operation, the process of identifying a defective element even slower and more difficult. 因此,当这种故障最终被识别时,不幸的是,系统故障的时间可能已足够危害一个或更多组件或甚至是被制冷的负载。 Accordingly, when such a fault is finally identified, Unfortunately, the time of system failure may be sufficient to harm one or more components or even refrigerated load. 除了该复杂情况之外,在大多数情况下识别缺陷的过程是根据经验进行的,基于维护人员的先前经验。 In addition to this complex situation, the defect identified in most cases the process is carried out empirically based on previous experience in the maintenance personnel.

[0016] 此外,一些制冷系统故障是由使用者不当操作引起的和由该制冷系统周围的人或甚至与该制冷系统以不当方式相互作用的人忽视使用识别引起的。 [0016] In addition, some of the refrigeration system failure caused by improper operation by the user and the person or even improperly refrigeration system by the interaction of people around the refrigeration system using the identified due to neglect.

[0017] 然而,当制冷系统的概念外推至用于诊断目的且考虑常用家用电器时,同类型故障和关于这些故障识别的困难也会发生。 [0017] However, when the outer cooling system is pushed to the concept used for diagnostic purposes and considering common household appliances, the same type of fault and the fault identification of these difficulties will occur.

[0018] 在本文中,到目前为止,现有技术尚未公开任何这样的诊断系统或方法,即该诊断系统或方法能通过使用检测制冷系统或家用电器内部量值以及表示环境或被制冷负载的特性的量值两者的装置来检测制冷系统组件或常用家用电器中的故障,在制冷系统的情况下,该系统或方法向使用者报警需要预防性维护,从而最小化设备停工期。 [0018] Herein, to date, the prior art has not disclosed any such diagnostic methods or systems, i.e., the diagnostic system or method for detecting a refrigeration system through the use of household appliances or the internal environment or indicating the magnitude of the cooling load It means the magnitude of both the characteristics to detect faults or refrigeration system components used in household appliances, in the case of refrigeration system, an alarm system or method which requires preventative maintenance to the user, thereby minimizing equipment downtime.

[0019] 由于现有技术中该差距,现在还没有制冷系统的压缩机或其他旋转元件通过一种能检测故障并使用检测压缩机内部和外部量值的装置的诊断系统或方法而被诊断,从而向使用者报警需要预防性维护。 [0019] Since the gap between the prior art, there is no compressor or other rotating element by means of a refrigeration system and can be detected using the fault diagnosis system or method for detecting a compressor inside and outside of the apparatus is the magnitude of the diagnosis, so as to alert the user need preventive maintenance.

[0040] 此外,本发明在其诊断系统和方法中也考虑了诊断家用电器而不仅仅是制冷系统的操作状况的可能性。 [0040] Further, the present invention in its diagnostic system and method are also contemplated the possibility of diagnosing the operating condition of the home appliance and not only the refrigeration system. 家用电器可以是可被本发明的诊断方法和/或诊断系统所诊断的现有技术所知的任何电器。 Household appliances may be diagnosed by the diagnostic methods and / or diagnosis of any electrical system of the invention is known in the art. [0041] 量倌和传感器 [0041] The amount of the sensor and the groom

[0042] 为了本发明的诊断系统和方法的操作,需要测量一些量值。 [0042] To operate the diagnostic system and method of the present invention, a number of values ​​to be measured.

[0043] 因此,在制冷系统或家用电器中所涉及的一些物理量值当中,优选将用在本发明的系统和方法中的那些量值可被分为两组,也就是: Those values ​​[0043] Thus, in a refrigeration system, or some physical magnitudes involved among household appliances, preferably with the system and method of the present invention may be divided into two groups, namely:

[0045] (ii)制冷系统和被制冷的环境的参数,或家用电器的参数。 [0045] (ii) cooling the refrigeration system and environment parameters, or the parameters of the home appliance. 如下所述,第一组在确定系统的操作状况时更重要,而第二组用于增强或确认基于第一组所作的分析。 As described below, the first group is more important in determining the operating conditions of the system, the second set of reinforcing or confirmation for the first group based on the analysis made.

[0046] 更具体地,组⑴的量值为制冷系统和/或家用电器的组件的机械振动,而振动是由组件与至少一个压缩机或其他可并入制冷系统的旋转元件相关联的事实引起的。 [0046] More specifically, the group ⑴ magnitude of mechanical vibration of the refrigeration system and / or components of household appliances, the fact that vibrates at least one compressor assembly or cooling system may be incorporated into other rotary element associated caused. 该组进一步包括由制冷系统和/或家用电器周围环境中人运动产生的噪声。 The set further comprises a noise generated by the refrigeration system and / or the home appliance surrounding human movement.

[0048] 因此,由于需要测量上述量值,需要多个传感器以检测所有这些参数,使得本发明的系统和方法可基于收集的数据诊断制冷系统。 [0048] Accordingly, since the need to measure the magnitude of the above, a plurality of sensors required to detect all of these parameters, so that the system and method of the present invention may be based on the diagnostic data collected by the refrigeration system.

[0049] 因此,至少一个传感器2或多个传感器2负责检测组(i)的量值,即,负责检测制冷系统组件、作为整体的制冷系统和/或家用电器的机械波信号(也可被称为机械振动或声压波),传感器2优选包括:加速度计、扩音器或音频传感器,该扩音器或音频传感器能检测组件的前面提及的机械振动或声压波,或甚至能检测由在制冷系统和/或家用电器周围环境中流通或存在的人产生的噪声。 [0049] Thus, the magnitude of 2 or more of at least one sensor is responsible for detecting sensors 2 group (i), i.e., the system components responsible for detecting the refrigerant, the refrigeration system as a whole and / or mechanical wave signal of the home appliance (also may be referred to mechanical vibrations or acoustic pressure waves), preferably 2 sensor comprising: an accelerometer, a microphone or an audio sensor, the sensor can detect a microphone or an audio mechanical vibrations or acoustic pressure wave in front of the mentioned components, or even detectable noise generated by a person present in the circulation or refrigeration systems and / or household appliances surrounding environment. 但是,可使用所述优选实施方式的任意组合,即,加速度计、扩音器或音频传感器可单独使用,或者加速度计可与一个或多个扩音器一起使用、或者扩音器可与一个或多个音频传感器一起使用等等。 However, the preferred embodiment may be used in any combination, i.e., an accelerometer, a microphone or audio sensors may be used alone, or an accelerometer may be used with one or more loudspeakers or loudspeaker may be a or the like with the use of a plurality of audio sensors. 因此,这些传感器的组合显然并不是本发明范围的限制因素。 Thus, the combination of these sensors is clearly not intended to limit the scope of the present invention factors.

[0050] 多个负责检测组(ii)量值的第二传感器3优选包括:至少一个测量制冷系统(如果可适用的话,和家用电器)的内部温度的温度传感器;至少一个测量制冷系统和/或家用电器外部的温度的温度传感器;以及电压和电流传感器。 [0050] is responsible for detecting a plurality of groups (ii) the magnitude of the second sensor 3 preferably comprises: measuring at least one refrigeration system (if applicable, and household appliances) in the internal temperature of the temperature sensor; measuring at least one refrigeration system and / household appliance or the external temperature of a temperature sensor; and a voltage and current sensors.

[0053] 在制冷系统的情况下,外部温度传感器通常优选地放置在制冷系统的外部中,而内部温度传感器放置在可检测被制冷的负载区域中的温度的位置中。 [0053] In the cooling system, an external temperature sensor is preferably positioned generally in the external refrigeration system, an internal temperature sensor and the detected temperature may be placed in a refrigerated area load position. 此外,对于所述多个第二传感器3,电压和电流传感器需要放置在靠近组件的位置,由此可产生诊断的完善或确认,如下所述。 In addition, the plurality of second sensors 3, voltage and current sensors need to be placed at a position close to the assembly, thereby generating a complete or confirm a diagnosis, as described below.

[0054] 频谱特征[0055] 本发明的诊断系统和方法使用频谱特征,使得制冷系统的操作状况可被确定而使用者或负责维护的人员可得到报警。 [0054] The spectral characteristics [0055] The diagnostic system and method of the present invention is the use of spectral characteristics, so that the operating condition of the refrigeration system may be determined and the user or person in charge of maintenance can be obtained alarms.

[0056] 频谱特征可定义为组件基于时间的行为转化成频域中的量值的转化,换言之,频谱特征等于振动元件(电机、压缩机等等)的频率谱线。 [0056] The spectral characteristics of conversion may be defined as the time-based behavior of the component transformed into the frequency domain values, in other words, the spectral characteristics of the vibration equal to the frequency spectrum components (motor, compressor, etc.). 在本发明的情况下,频谱特征优选由所述多个第一传感器2生成,这些第一传感器2意图检测制冷系统和/或家用电器的机械振动或声压波,也意图检测制冷系统和/或家用电器周围环境的噪音,即频谱特征由机械波信号(振动和声音)生成。 In the present invention, is preferably generated by the spectral characteristics of the plurality of first sensor 2, the sensor 2 is intended to detect a first refrigeration system and / or mechanical vibrations or acoustic pressure waves of the home appliance, the refrigeration system are intended to detect and / ambient noise or the home appliance, i.e., the spectral characteristics of the signal generated by the mechanical waves (sound and vibration). 因此,所讨论的量值首先由它们各自的传感器检测,然后在应用特定算法之后生成频率谱线,即频谱特征。 Thus, the magnitude discussed first detected by their respective sensor, and generating a frequency spectrum after application of a specific algorithm, i.e. spectral characteristics. 优选地,该特定算法为傅立叶变换(FFT) 型。 Preferably, the specific algorithm is a Fourier Transform (FFT) type.

[0057] 因此,考虑到处在正常操作状况的制冷系统的组件以确定频率振动且具有确定振幅(二者均通过其频谱特征识别),操作中即使最小的振动都将改变该组件通常的频率和振幅并且该组件将开始以其他频率和振幅而振荡,即处于异常操作状况。 [0057] Accordingly, in consideration of the refrigeration system components everywhere normal operating conditions to determine the frequency of the oscillation amplitude determined range (both identified by its spectral characteristics), even the smallest operation will change the oscillation frequency of the assembly and generally the amplitude and the assembly will begin at other frequencies and oscillation amplitude, i.e., is in an abnormal operating condition.

[0058] 如果我们以电机或甚至压缩机为例,这可被观察到。 [0058] If we take the motor or even compressor, for example, which can be observed. 在此情况下,当压缩机在正常操作状况下振动时,其可产生特定频率和振幅的能听到的噪声,但是当电机例如发生故障时噪声的声音改变。 In this case, when the vibration of the compressor under normal operating conditions, which can produce a particular frequency and amplitude of the noise can be heard, but when the motor failure, for example, noise sound change. 换言之,如果声音由一系列频率和与所述频率相关的振幅构成,由于振荡频率和相关振幅已改变,因此该故障电机的改变的声音自动指示出其正常操作状况的改变。 In other words, if the amplitude of the sound associated with the number of frequencies and frequency structure, since the oscillation frequency and amplitude are related changes, thus changing the sound of the automatic machine fault indicating changes their normal operating conditions.

[0059] 基于该原因,操作状况的改变可通过将正常操作状况下获得的频谱特征与从最近检测到的振动生成的频谱特征进行比较来检测。 [0059] For this reason, to change the operating condition of the spectral characteristics can be obtained under normal operating conditions is compared with the spectral characteristics of the most recently detected vibration generation is detected by. 因此,与所述多个第一传感器2相关联的作为整体的系统和/或家用电器或其组件的操作状况被适时地监测。 Thus, the plurality of first sensor 2 is associated with timely monitoring system as a whole and / or operating conditions of the household appliance or a component thereof.

[0060] 类似地,在检测制冷系统和/或家用电器周围环境中的人的情况中,测得的噪声被转换到频域,从而使得与人数量相关的噪声的频率模式生成,当该模式改变时,通过比较标准状况的频谱特征与最近从测得声音的机械振动生成的频谱特征能获得行为变化的清晰读数。 [0060] Similarly, in the case of detecting the refrigeration system and / or household appliances in the environment surrounding the person, the measured noise is converted to the frequency domain, so that the number of people associated with the frequency pattern noise is generated, when the mode when the change, the spectral characteristics of mechanical vibration generated by the sound from the nearest available frequency spectrum characteristics as measured by comparing standard conditions can get a clear reading of the behavioral change.

[0061] 操作模式 [0061] The mode of operation

[0062] 对于要确认的系统诊断,如上所述,系统的标准频谱特征需要与从当前操作状况生成的频谱特征进行比较。 [0062] To confirm the diagnosis for the system, as described above, the spectral characteristics of the standard system needs to be compared with the spectral characteristics generated from the current operating conditions. 为此,本发明的方法和系统依赖于存储在数据库中的标准频谱特征。 For this purpose, the method and system of the present invention relies on the standard spectral characteristics stored in the database. 应进一步指出的是,本发明的系统和方法可使用与操作状况相关的频谱特征范围或间隔来做出诊断。 It should further be noted that the system and method of the present invention can be used associated with a characteristic spectral range of operating conditions to make a diagnosis or spacer. 在这种情况下,将会在生成的特征与数据库中存储的特征范围之间做比较。 In this case, the comparison between the characteristic range will be stored in the database and the generated feature. 此外,上述数据库有可能具有一系列标准值,用于将不生成频谱特征的参数(也就是: 电流、电压和温度),即非振动信号。 Further, the database is possible to have a series of standard values ​​for the characteristic parameters of the spectrum is not generated (ie: current, voltage, and temperature), i.e. non-vibrating signal. 因此,可在例如标准电压和读数电压之间做比较以完善或确认已通过比较频谱特征所获得的诊断结果。 Thus, for example, comparison between a reference voltage and the voltage readings to improve or confirm the diagnosis by comparing the spectral characteristics has been obtained. 本发明的系统和方法也考虑了为一个以上振动方式存储操作模式的可能性。 The system and method of the present invention also contemplates the possibility of more than one oscillation mode memory operation mode. 概念上,振动方式为系统和/或其组件振动的水平,即组件被设定在此振荡的水平。 Conceptually, the horizontal vibration mode of the system and / or vibration components, i.e., the level of this component is set oscillating. 例如,设定工作在0或3600rpm的压缩机包括两个振动方式,也就是:0和3600rpm。 For example, the work of the compressor is set to 0 or 3600rpm comprises two vibration modes, namely: 0 and 3600rpm. 另一方面,可变速压缩机由于其旋转的可变性可包括多种多样的振动方式。 On the other hand, due to the variable speed compressor rotation variability may comprise a variety of modes of vibration.

[0063] 因此,数据库存储对应于组件或系统具有的每个振动方式的频谱特征和操作状况模式,即,每个操作方式对于给定的相关操作状况生成特定的频谱特征。 [0063] Accordingly, the database stores the corresponding spectral characteristics and operating conditions for each mode of vibration modes in the component or system, i.e., each mode of operation for a given operating conditions associated generate specific spectral characteristics.

[0064] 在此情况下,将仅在限定同一振动方式或与该同一振动方式相关的特征之间做比较,即,如果生成的特征是基于3600rpm下振动的读数,该生成的特征将与相同旋转的操作状况的标准频谱特征做比较。 [0064] In this case, would be defined only between the same vibration means or features associated with the same vibration mode of the comparison, i.e., if the feature is generated based on the vibration readings 3600rpm, the generated feature with the same compare the spectral characteristics of the standard rotating operating conditions.

[0065] 优选地,制冷系统的组件具有至少两个操作方式,并且如果可适用的话,可具有两个以上的操作方式,可变速压缩机的情况就是如此。 [0065] Preferably the assembly, a refrigeration system having at least two operating mode, and if applicable, may have two or more operation mode, where the variable speed compressor is the case.

[0066] 使用记录 [0066] usage record

[0067] 当诊断系统和方法检测通过多个第一和第二传感器获得的参数和振动时,与这些连续读数相关的数据被存储在前述的数据库中。 [0067] When the diagnostic system and method for detecting when a plurality of first and second parameters and the vibration sensor is obtained, data associated with these consecutive readings are stored in the database. 这些数据包括读数的日期和时间,正被检查的组件及其相应的操作状况,从而使得使用记录被创建。 These data include the date and time of reading, the component being inspected and its corresponding operating conditions, so that the usage record is created.

[0068] 该使用记录包括每个测量的数据,从而使得有可能跟踪系统和/或家用电器及其组件随时间的操作状况。 [0068] the usage record comprises data for each measurement, so that the operating conditions of possible to track systems and / or household appliances and components thereof over time. 因此,万一制冷系统和/或家用电器遭遇轻微偏差型的故障,所述故障将容易被检测,因为使用者或负责维护的人员将经常注意到系统在其操作行为上呈现出轻微变化,因此排除了把轻微偏差误认为是由于环境变化导致的操作状况的微小变化的可能性。 Thus, if the refrigeration system and / or household appliances encounter slight deviation type fault, the fault will be readily detected, since the user or person in charge of maintenance is often noted that the system presents a slight variation in their operating behavior, He ruled out the possibility of small changes due to environmental changes caused by the operating conditions of a slight deviation mistaken yes.

[0069] 实际上,当分析使用记录时可消除该混淆,因为制冷系统和/或家用电器的物理量值的行为趋向于适应环境变化(例如温度变化)并在一段短时间后回到平衡,而在失效故障的情形下,它们趋向于在一段更长时间内保持在非正常操作状况的操作状况。 [0069] In fact, when analyzed using a recording can eliminate the confusion because the behavior of the refrigeration system or a physical magnitude and / household appliances tend to adapt to environmental changes (e.g. temperature variations), and return to equilibrium after a short period of time, and in case of failure the fault, they tend to remain in a non-operating conditions in normal operating conditions within a longer time period.

[0070] 报警和发信号 [0070] Alarm and signaling

[0071] 比较完频谱特征(以及如果可适用的话,其他不会生成频谱特征的量值)之后,本发明的系统和方法需要能向使用者或负责维护的人员报警可能的故障。 [0071] After comparing the spectral characteristics (and, if applicable, other spectral features does not generate magnitude), the system and method of the present invention need to be able to alert the user of possible malfunction or maintenance personnel responsible. 因此,本发明的系统和方法具有报警界面6,如其名所示,给使用者关于系统偏离正常操作状况的早期警告。 Thus, the system and method of the present invention has an alarm interface 6, as its name suggests, an early warning to the user about the system deviates from the normal operating conditions.

[0072] 优选地,报警界面6包括至少一个连接有便携式读取装置的显示器和/或终端,因此使得操作状况可以看到。 [0072] Preferably, the alarm interface 6 comprises at least one connection with a display and / or terminals of the portable reading device, so that the operating conditions can be seen.

[0073] 因此,使用周期地诊断制冷系统和/或家用电器的操作状况并通知使用者这些状况的本发明的系统和方法,可很容易地阻止对它们相应组件的损坏。 The system and method of the present invention [0073] Accordingly, the diagnosis cycle refrigeration system and / or operating conditions of the home appliance and to inform the user of these conditions may be readily prevented damage to their respective components.

[0074] 诊断系统 [0074] Diagnostic System

[0075] 既然已描述了诊断系统的组件和一些特性,也应描述形成所述系统的元件之间的相互作用。 [0075] Now that we have described some of the features and components of the diagnostic system should also describe the interaction between the elements forming the system. 因此,从图1可看到,本发明的诊断系统1包括:多个第一传感器2,多个第二传感器3,数字处理单元4,至少一个存储器单元5以及报警界面6。 Thus, can be seen from Figure 1, the diagnostic system of the present invention comprises: a plurality of first sensor 2, a second plurality of sensors 3, the digital processing unit 4, memory unit 5, and the at least one alarm interface 6. 应指出的是,考虑到所述多个第二传感器3对于本发明的实现而言是可选的,因此,图1图示了本发明的诊断系统的优选实施方式,结合了可选实施方式。 It should be noted that the view of the second plurality of sensors 3 for achieving the purposes of the present invention is optional, and therefore, FIG. 1 illustrates a preferred embodiment of the diagnostic system of the present invention, in conjunction with an alternative embodiment .

[0076] 如前所述,所述多个第一传感器2检测与制冷系统内部和外部的机械振动相关的量值,收集关于人员移动和制冷系统振荡的参数。 [0076] As described above, a plurality of first mechanical vibration sensor 2 detects the refrigeration system internal and external quantities related to collect parameters concerning movement of personnel and the refrigeration system oscillation.

[0077] 在这诊断系统的可选实施方式中,所述多个第二传感器3检测将支持和完善基于机械振动获得的诊断结论的量值。 [0077] In an alternative embodiment of this diagnostic system, the plurality of second sensor 3 detects the sound support and mechanical vibration diagnostic conclusions based on the obtained value.

[0078] 由所述多个第一和第二传感器2、3检测到的量值将被传输至负责将信息读数转换为参数以便获得诊断的数字处理单元4。 [0078] a plurality of said first and second sensors 2 and 3 detect the magnitude to be responsible for converting the information transmitted to the reading parameter so as to obtain diagnostic digital processing unit 4. 传感器和所述数字处理单元4之间的联系可通过电线和电缆建立,或者如果设计者和本领域技术人员偏好,可通过无线技术建立,且重要的是要指出数据传输装置不是限定本发明范围的因素,因此可使用其他装置、形式和方法。 4 the connection between the sensor and the digital processing unit can be established through the wire and cable, or if the designer preference and those skilled in the art, may be established through wireless technology, and is important to note that the data transmission device is not to limit the scope of the present invention factors, it is possible to use other devices, methods and forms.

[0079] 存储器单元5与数字处理单元4相连,存储器单元5在这数据库中存储制冷系统和/或家用电器的标准频谱特征和预先限定的参数值以及使用记录(从多个第一和第二传感器获得的数据的记录)。 [0079] The memory cells 5 is connected to digital processing unit 4, memory unit 5 stores the refrigeration system and / or the home appliance and a standard spectral features predefined parameter values ​​and using this database records (from the plurality of first and second recording the sensor data obtained). 这存储器单元5优选地为非易失型,例如:EPR0M、EEPR0M、FLASH寸寸。 This memory cell 5 is preferably a non-volatile type, for example: EPR0M, EEPR0M, FLASH begins.

[0080] 因此,对于要做出的制冷系统诊断,数字处理单元4被设为生成从所述多个第一传感器2获得的参数的频谱特征,即,从从至少一个传感器收到的信号中识别频谱参数,以将生成的特征与标准频谱特征进行比较并在存储器单元5数据库中输入使用记录。 [0080] Accordingly, the refrigeration system for the diagnosis, the digital processing unit 4 is set to be made to generate the spectral feature parameters obtained from said plurality of first sensor 2, i.e., from the at least one signal from the sensor received identifying spectral parameters, to characterize the features of the standard spectrum generated by comparing and inputs recorded in the memory unit 5 in the database.

[0081] 通过在最近生成的频谱特征与存储在数据库中对应于正常操作状况的那些频谱特征之间的比较,可立即检测出制冷系统是否具有完全失效型的故障,例如如果组件完全无效时。 [0081] By comparison between the spectral characteristics of those most recently generated spectral characteristics stored in a database corresponding to the normal operating condition can be detected immediately complete failure fault type whether the refrigeration system, for example if the component is completely ineffective.

[0082] 另一方面,万一制冷系统的组件表现出间歇工作行为,当使用记录制成可看时,其将指示该故障,因为系统或一个或多个组件随时间的活动的不规则已被识别。 [0082] On the other hand, in case of the refrigeration system components exhibit behavior intermittent operation, when a recording is made to see which will indicate the failure, or because of an irregular system of one or more components over time is active Identified. 同理适用于操作状况中的轻微偏差,如已讨论的。 The same applies to the operating condition of slight deviations, as already discussed.

[0083] 可选实施方式中,除了通过比较频谱特征做出的诊断之外,本发明的诊断系统考虑了其他可辅助确定操作状况的量值的可能性,且所述辅助工作作为确认目的的补充信息。 [0083] In an alternative embodiment, in addition to comparing the spectral characteristics of the diagnosis made by the addition, the diagnostic system of the present invention contemplates the possibility of other operating conditions can aid in determining the magnitude of, and the auxiliary working object as the confirmation Additional information. 例如,万一组件被发现处于完全无效的状况,可使用电流、电压、温度或其他不生成频谱特征的量值以验证和确认组件是否确实无效。 For example, if the component is found in a condition completely ineffective, using current, voltage, temperature, or other characteristics of the magnitude spectrum is not generated to verify and confirm that indeed components are invalid. 实际上,被读取但不会生成频谱特征的量值基于存储器单元5中存储的预定值而解译或不解译。 In fact, it is read but not generated based on a predetermined magnitude spectral feature value stored in the memory unit 5 and is not interpreted or interpreted.

[0084] 应进一步指出的是,这数字处理单元4与报警界面6相连,使得与制冷系统的操作状况相关的数据制成获得后通过所述界面6立即就可看到。 [0084] It should further be noted that the digital processing unit 4 which is connected to the alarm interface 6, so that the data relating to the operating conditions of the refrigeration system through the interface 6 can be seen immediately after formed is obtained.
