“…In fault diagnosis of automatic production machinery and equipment, more than 60% of the faults are electrical malfunction [11][12][13][14][15][16]. Since the internal environment of such equipment usually has the characteristics of large current, high voltage, and slow heat dissipation, when operating continuously for a long time, the temperature rise will affect the operational stability of the equipment, and further resulting in thermal failure of the equipment [17][18][19][20][21]. Manual hand-held infrared thermometers can measure the temperature of the equipment easily at close range, and accurately locate the positions of the thermal faults, but this method requires large workload and it couldn't monitor the working status of the equipment in real time [22][23][24][25].…”

The thermal fault diagnosis of automatic production machinery and equipment and the analysis of its reliability are of positive meanings for promoting the advancement of diagnosis technology and guaranteeing the safe and reliable operation of the equipment. For this reason, this paper attempts to research the thermal fault diagnosis of transmission system in automatic production machinery and equipment and analyze its reliability. At first, with a transmission device as an example, thermal fault diagnosis was performed on the device and its reliability was analyzed; then, the paper gave the overall structure of the thermal fault diagnosis system and elaborated on the diagnosis flow. After that, the distribution of water temperature in radiator water channels was described in detail, and a temperature model of the transmission device were constructed. At last, this paper fully considered the possible interference factors in actual production, and used 3 kinds of parameter models for systematic identification, and the experimental results proved the effectiveness of the proposed model.
