s706: determining the flow of the flash according to the first image information;
s708: matching the second image information with the second model image, and determining the type of the overflowing aggregate according to the matching result;
s710: determining the proportion of different types of aggregates in the overflowed aggregates according to the second image information;
s712: and (5) counting and sending the flash information.
Specifically, the processor can count the flow of the flash, the type of the aggregate and the proportion of the aggregates of different types, and the like, display the counting result on the display of the flash detection device, or transmit the counting result to the mobile display device through the information transmission device, and send out flash prompt information to prompt an operator to check the mobile display device, so that the operator can judge the flash condition and provide data support.
According to the flash detection method provided by the invention, the first image information at the outlet of the flash pipe 104 is acquired by the first image collector 106, the processor is matched with the pre-stored first model image through the first image information, if the first image information is matched with the first model image, the flash phenomenon at the current moment is determined, and then a flash prompt is sent out to prompt an operator. The automatic monitoring of the flash phenomenon in the closed flash bin 102 is realized while the environmental protection requirement is ensured, and further the production can be guided in time aiming at the flash phenomenon, so that the safety and the production efficiency of the production process are improved. Further, the second image information is matched with a second model image stored in advance, and then the type of aggregate falling into the flash bin 102 in the flash process is determined according to the matching result.
