Carrier roller belt abnormity monitoring system based on shape memory alloy

The utility model belongs to the field of bulk material logistics equipment monitoring, and relates to a carrier roller belt abnormity monitoring system based on shape memory alloy, which comprises a mounting base, a middle bracket and a side bracket which are arranged on the mounting base, and a plurality of carrier roller shafts which are respectively arranged between the middle bracket and the side bracket, each carrier roller shaft is correspondingly provided with a carrier roller through a carrier roller bearing; a plurality of monitoring module supports are further arranged on the mounting base, and shape memory alloy monitoring modules are fixed to the monitoring module supports and used for monitoring the temperature of the carrier roller and the temperature of the belt at the same time. By monitoring the state of the connecting circuit of the monitoring module made of the shape memory alloy, the abnormal temperature condition of the carrier roller and the belt can be effectively found; the design of
