摘要
Abstract
In response to the problems of lost packages and system downtime caused by magnetic parcels adhering to conveyor devices in the letter sorting system,a weak magnetic detection method based on an array magnetic sensor and a gate logic circuit is proposed.A sliding window filtering method is proposed to deal with the magnetic interference noise caused by the motor's starting and stopping.The magnetic field distribution characteristics of weak magnetic items are analyzed,and the rules of rapid decay of the magnetic field in the vertical direction and the intensity on the surface are studied.A structural design method combining a chip magnetic sensor and a thin aluminum plate is proposed for the logistics detection platform with limited space.The experimental results on the logistics sorting platform show that the detec-tion rate of the method is higher than that of the conventional method and can detect weak magnetic par-cels at a speed of 1 m/s with 100%accuracy.关键词
