In order to monitor the catering oil smoke emission status in real time and improve the monitoring accuracy
a catering oil smoke monitoring system based on information fusion is proposed.The terminal uses STM32 as the control center to drive the sensors
and the MS1100
MQ—7
and TGS2600 sensors detect the smoke parameters(toluene
formaldehyde
CO
and benzene concentrations);the information processing uses i.MX287 as the calculation unit to migrate the cloud computing to i.MX287
the fumes parameters are fused by back propagation(BP)neural network optimized by genetic algorithm
which improves the system operation efficiency and monitoring accuracy.Use the GPRS function of SIM900 A to upload the monitoring status of the oil smoke and the switch state of the fan purifier to the server for data display.Tests show that the monitoring accuracy is high
which can meet the monitoring requirements of catering fume.
