Dry and wet identification method of bagged garbage

Abstract

The invention provides a method for identifying dryness and wetness of bagged garbage, comprising steps: S1, using capacitance sensors, metal sensors and temperature and humidity sensors, respectively measuring the capacitance, metal strength, temperature and humidity of bagged garbage; The output value is used as a weight assignment to obtain unified data U; S3, compare U with the set threshold F, when U≥F, it is judged as wet garbage; when U<F, it is judged as dry garbage; and when d>0, judge There is metal; when d=0, it is judged to be metal-free. The present invention uses a plurality of different types of sensors to detect the dryness and wetness of bagged garbage, assigns weights and compensates the data output by each sensor to obtain unified data, and compares the threshold value verified by experiments in advance to make a qualitative judgment of dryness and wetness. The user only needs to put the bagged garbage in a fixed position, and the judgment result can be obtained in a few seconds. The identification process does not need to destroy the garbage bag, and the identification effect is better.

Description

technical field [0001] The invention relates to the field of garbage classification, in particular to a method for identifying dryness and wetness of bagged garbage. Background technique [0002] Bagged garbage is the most common garbage in daily life in China. Although garbage sorting is advocated, the implementation of garbage sorting is not effective, and manual sorting is still mostly relied on, which is time-consuming and labor-intensive. Due to the complexity of the garbage in bagged garbage, there is a lack of effective detection methods on the market. At present, the common method is probe detection. Since the position where the probe is inserted is highly random, the judgment results are highly accidental. Moreover, the probe-type detection will destroy the outer packaging of the bagged garbage, which will cause liquid to flow out of the wet garbage bag, resulting in odor and pollution. Others use infrared detectors to detect the types of garbage, but the detection...

[0002] Bagged garbage is the most common garbage in daily life in China. Although garbage classification is advocated, the implementation of garbage classification is not effective, and manual classification is still mostly relied on, which is time-consuming and labor-intensive.

Due to the complexity of the garbage in bagged garbage, there is a lack of effective detection methods on the market. At present, the common method is probe detection. Due to the randomness of the position where the probe is inserted, the judgment result is highly contingency

Moreover, the probe-type detection will destroy the outer packaging of bagged garbage, which will cause liquid to flow out of the wet garbage bag, resulting in odor and pollution

Some use infrared detectors to detect the types of garbage. For complex types of bagged garbage, the detection effect is still not good
