Embodiment Construction
[0034] Next, this specific embodiment (referred to as "embodiment") will be described in detail with reference to the drawings as appropriate.
[0035] [abnormality diagnosis device 1]
[0036] figure 1 It is a figure which shows the structural example of the management system Z in this embodiment.
[0037] The management system Z has at least one system D to be diagnosed, a data terminal 5 installed in the service center C2, and an abnormality diagnosis device 1 installed in the remote monitoring center C1.
[0038] A system Da to be diagnosed among systems D to be diagnosed is equipped with two air conditioners 2 and a control device 3 connected to these air conditioners 2 .
[0039] The air conditioner 2 is a target of diagnosis by the abnormality diagnosis device 1 and controls the air in the room to be in an arbitrary state. The air conditioner 2 is a multi-type air conditioner, an industrial air conditioner for cooling a room in which a computer is accommodated, or th...

The present invention provides an abnormality diagnosis device and an abnormality diagnosis method that can improve the accuracy in the abnormality diagnosis of equipment. This abnormality diagnosis device includes: a data type storage unit that stores data type information, wherein the data type information is used to determine which of the operating data acquired from the equipment is the information derived from the performance of the equipment itself, that is, the performance, and the information related to the operation of the equipment, that is, the operating conditions; a learning datastorage unit stores learning data which is the result of learning the operating data in advance, and is used to determine whether the operating data is abnormal or normal; an abnormality determinationunit which acquires new operation data that is newly acquired operation data from the equipment and determines whether the new operation data is abnormal or normal based on the learning data; and a learning data addition unit adds learning data based on the new operating data if the new operating data determined to be abnormal is information related to operating conditions.
Description
technical field [0001] The present invention relates to the technology of an abnormality diagnosis device and an abnormality diagnosis method for diagnosing an abnormality of equipment. Background technique [0002] Aiming at devices that are expected to operate stably, such as air conditioners, a system for performing abnormality diagnosis based on the operating data thereof is provided. In such an abnormality diagnosis, it is judged (diagnosed) whether the state of the device is in a normal operating state or an abnormal state, and as a result, when it is judged to be in an abnormal state, an abnormality is reported. Here, the abnormal state refers to a state in which some kind of failure or deterioration occurs in the device. Such abnormality diagnosis is expected to reduce downtime of equipment based on early detection of deterioration or failure. [0003] The state of the air conditioner is detected by a sensor or the like, and these abnormalities are diagnosed using ...
