Embodiment Construction
[0051] The present invention will be further elaborated below through specific embodiments in conjunction with the accompanying drawings.
[0052] The invention mainly consists of three parts: establishment of bonded breakout / normal working condition sample library, random sample set hierarchical clustering, breakout identification and alarm.
[0053] Step 1. Establish bonded breakout / normal working condition sample library
[0054] figure 1 Create a flow chart for bonded breakout / normal working condition sample library. Depend on figure 1 It can be seen that the establishment of the sample library mainly includes the following sub-steps:
[0055] (1) Extract historical temperature data, which includes two parts: breakout temperature data where real bonding occurs and temperature fluctuation data under normal working conditions.
[0056] 1.1) For the actual bonded breakout temperature, mark the moment of the highest temperature of the first row of galvanic couples where th...
