Abstract: For relief food prone to deterioration and damage in the long-distance transportation problem,designed and implemented based on artificial olfactory relief food transportation metamorphic real-time monitoring system of network technology,the system hardware,d/a conversion module controlled by MCU,the sense of smell sensor circuit,sound and light alarm circuit and so on,through the system software realized the transportation of container information connected with the control center,control center by wireless sensor network real-time monitoring relief food,after deterioration in individual food can discover and handle in time,thereby reducing losses.Through the system experiments show that the system works stable,strong real-time performance,transmission of data information is correct and can meet the demand of remote monitoring of relief food.
