The automatic checkout equipment can automatically check out the electromagnetic products such as a mobile phone in the pocket of the clothes to be washed with convenience and economy and has higher responsiveness, strong anti-interference ability and high reliability by adopting the non-contact detection.
Description
Technical field
The utility model relates to a kind of automatic detection device that whether washed pocket is also had electromagnetic product such as mobile phone.
Background technology
The Hall switch inductor: Hall element is a kind of magnetoelectric conversion element based on Hall effect, can be divided into switch output type and linear output type.Here only use the switch output type, promptly the Hall switch inductor 1.It is a kind of with voltage-stabiliser tube, the semiconductor Hall plate, and amplifier, circuits for triggering and output driver all are integrated in the IC apparatus on the chip piece.The magnetic induction intensity in vertical chip front is depended in the switch motion of Hall switch inductor.Obtain the analog signal of an amplification behind the Hall voltage process amplifier, and its shaping is changed into data signal output by circuits for triggering.The Hall switch inductor is output as the constant amplitude voltage signal, so signal stabilization is reliable.
The inductive proximity transducer: it is made up of detecting element, detection unit, amplifying unit, integer unit and output unit etc.The detecting element that this sensor internal is installed is made up of magnetic test coil and high-frequency generator, power up the electromagnetic field that the back magnetic test coil produces an alternation, when metal object during near electromagnetic field, the magnetic flux density of metal surface changes and produces induced-current---and eddy current, always the flow direction with magnetic test coil is opposite for the magnetic flux that eddy current produces.Because the effect of eddy current increases the magnetic test coil energy consumption, factor of merit descends, and amplitude reduces, so that the blocking of oscillator.Otherwise when metal objects during away from this active region, oscillator is starting oscillation again.After testing circuit detects the state variation of amplitude device, be converted to a switching value signal.
With the quickening pace of modern life, people's automation, intelligent level is also more and more higher.Communication has mobile phone, wash clothes and use washing machine, yet the details in the life but becomes easier to be out in the cold.Mobile phone, electromagnetic equipments such as mp3 are placed on forgets in the pocket that the thing of taking out and putting the laundry machine washing into often has generation.Though washing machine is convenient, be difficult for finding in the pocket whether mobile phone etc. is arranged, caused unnecessary loss to a certain extent.
Summary of the invention
The purpose of this utility model provides a kind of convenience in order to overcome above-mentioned deficiency, and the economically viable automatic detection device that whether washed pocket is also had electromagnetic product such as mobile phone is to reduce unnecessary loss.
The purpose of this utility model can realize by following measure:
A kind of use in washing machine pocket remains automatic checking device, it is characterized in that around the middle part of washing machine drum, evenly being provided with Hall switch inductor integrated chip, Hall switch inductor integrated chip connects the alarm indication device by power amplifier, the place of washing machine drum two side handrails, the inductive proximity transducer is installed on one side, another side is installed the alarm indication device, inductive proximity transducer output signal is received the display unit that receives the report for police service behind the A/D converter, and the alarm indication device is made up of light emitting diode and buzzer.
Advantage of the present utility model has:
Whether the utility model can just washed pocket also has detecting automatically of electromagnetic product such as mobile phone, convenient economical, simultaneously owing to adopt contactless detection, has higher response, strong antijamming capability, high reliability.
Description of drawings
Fig. 1 is the utility model fundamental diagram.
Fig. 2 is a structure chart of the present utility model.
The specific embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the utility model evenly is provided with Hall switch inductor integrated chip 1 around the middle part of washing machine drum, Hall switch inductor integrated chip 1 connects alarm indication device 3 by power amplifier 4, the place of washing machine drum two side handrails, inductive proximity transducer 2 is installed on one side, another side is installed alarm indication device 3, inductive proximity transducer 2 output signals are received the display unit 3 that receives the report for police service behind the A/D converter 5, and alarm indication device 3 is made up of light emitting diode and buzzer.
Hall switch inductor integrated chip 1 is installed at the bottom of wash bucket, and its output signal is amplified rear drive light emitting diode and buzzer work through simple power amplifier 4.Circular object also is inductive proximity transducer 2 and alarm indication device 3 when being handgrip.
2 of inductive proximity transducers are to the metal objects sensitivity, simultaneously, because the alternating magnetic field that higher-order of oscillation coil produces is scattering, when the front end of the continuous proximity transducer of metal objects in the clothing, can trigger the variation of sensor states.Be translated into data signal.It is 1 that state variation is set: red light emitting diodes is bright, and buzzer rings simultaneously; Do not become 0: the emitting red light diode does not work, and buzzer is sounding not.
In addition, the detection of inductive proximity transducer 2 is apart from size, the metal material of meeting because of measured object, even the kind of metal material surface coating is different with thickness and different, so by detection the distance of electric inductor is set, makes generally speaking slide fastener is not exerted an influence.
The Hall switch inductor is connected with the mains, and electric current in the conductive material and external magnetic field interact and produce electromotive force.When around when having the mobile phone of electromagnetic field to enter cylinder the magnetic induction intensity perpendicular to chip front side change, trigger the switching effect of Hall switch inductor.Obtain the analog signal of an amplification behind the consequent Hall voltage process amplifier, and by circuits for triggering its shaping is changed into data signal output, be set this moment is 1 state.This signal amplifies the luminous and buzzer of the luminous red diode of rear drive through simple power amplifier 4.Otherwise be 0, light emitting diode does not work, and buzzer is sounding not.
