Bagged garbage dry and wet identifying method

Abstract

The invention provides a bagged garbage dry and wet identifying method. The bagged garbage dry and wet identifying method comprises the steps: S1, a capacitance sensor, a metal sensor and a temperature and humidity sensor are adopted to measure the capacitance, metal strength, temperature and humidity of bagged garbage correspondingly; S2, output values of all the sensors are subjected to weight assignment, and a unified datum U is obtained; and S3, U is compared with a set threshold value F, when U is larger than or equal to F, the bagged garbage is judged to be wet, when U is smaller than F,the bagged garbage is judged to be dry, when d is larger than 0, it is judged that metal exists, and when d is equal to 0, it is judged that no metal exists. The various different types of sensors are adopted to detect dry and wet of the bagged garbage, data output by all the sensors are subjected to weight assignment and compensated to obtain the unified datum, compared with the threshold valueverified through a test in advance, as for dry and wet qualitative judgment, a user only needs to place the bagged garbage into a fixed position in the whole process, the judgment result can be obtained only through a few seconds, a garbage bag does not need to be damaged in the identification process, and the identification effect is good.

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
