Abstract
Disclosed in the invention is a method for detecting metal impurities in a material. When a high-frequency oscillator is electrified and works, a high-frequency current is generated in a metal coil connected with the oscillator; when a metal-contained granular or powdery material enters a discharging channel provided with a metal coil around, the high-frequency current flowing through the metal coil can make a small change; an oscillator detector detects the change and a signal is amplified by a power amplifier; the signal is then converted into a digital signal by an A/D conversion module and the converted signal is transmitted to a single-chip microcomputer; and the single-chip microcomputer transmits an oscillator digital signal to a main controller and a hand-held terminal by a 3G wireless data transmission module. According to the invention, the 3G wireless data transmission module transmits a real-time situation detected by a metal detector to the main controller or hand-held terminal by a 3G network and thus the operator can get working conditions of metal detection and detection situations in real time, thereby carrying out operation effectively and guaranteeing effective elimination of metal impurities in the material.
Description
Technical field
the present invention relates to package packing machine field, specifically a kind of method detecting metallic impurity in material.
Background technology
Before food or medicine are packed, need to carry out metal detection to itself, prevent metallic particles or impurity to be mixed into wherein.Existing metal detector only can detect metallic impurity, but people but cannot learn concrete detection case, and takes appropriate measures, even if cause metallic impurity to be detected, also cannot carry out the problem accurately rejected.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of method detecting metallic impurity in material, the information of detection can be flowed to master controller by wireless transport module, operating personnel can grasp operating mode and the detection case of metal detection in real time, thus effectively operate, ensure effective rejecting of metallic impurity in material.
Technical scheme of the present invention is:
A kind of method detecting metallic impurity in material, when high frequency oscillator works on power, high-frequency current is produced in connected wire coil, when the particle containing metal or granular material enter surrounding the tapping channel of wire coil is installed time, can cause the high-frequency current flowing through wire coil that small change occurs, oscillating detector is detected this change and by power amplifier, signal is amplified, single-chip microcomputer is transferred to after converting digital signal to finally by A/D modular converter, single-chip microcomputer passes through 3G wireless data transfer module vibration digital data transmission to master controller and handheld terminal.
Described single-chip microcomputer is connected with clock module, when single-chip microcomputer receives vibration digital signal, clock module real time record current time information, and this temporal information is stored in storer.
Advantage of the present invention:
The real-time condition that metal detector detects is transferred to master controller or handheld terminal by 3G network by 3G wireless data transfer module of the present invention, operating personnel are made to grasp operating mode and the detection case of metal detection in real time, thus effectively operate, ensure effective rejecting of metallic impurity in material; Clock module of the present invention can record the temporal information that metallic impurity detect, and is stored in storer by this temporal information, and handled easily personnel transfer and check, thus it is defective to determine which batch materials detects.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention.
