AIR CONDITIONING SYSTEM DIAGNOSTIC DEVICE

摘要

An air conditioning system diagnosis apparatus is obtained in which a refrigerating cycle is automatically analyzed and waveform data in messages flowing in a general-purpose network is acquired and automatically analyzed according to the analysis result of the refrigerating cycle, thereby achieving, with a single apparatus, diagnosis and monitoring of errors in the refrigerating cycle and in the general-purpose network. A trigger output means 106 creates a trigger on the basis of a waveform analysis condition 1052 and the analysis result of a packet received from a message analyzing means 102; when receiving the trigger, a waveform input means 107 reads out waveform data stored in a buffer; waveform analyzing means 108 notifies a synchronization determining means 109 of the analysis result of the waveform data; the synchronization determining means 109 searches for the analysis result of a packet synchronized with the received analysis result of the waveform data.
