Description
Technical field
The utility model relates to electrical application technology, specifically self adaptation transparent plastic film shoe cover photoelectric detection system.
Background technology
It is cordless that existing electric intelligent shoe covers device detects what adopt to having or not of shoe cover, general infrared emission, the reception optoelectronic switch of adopting detected having or not of shoe cover, when having shoe cover to block, when its signal amplitude surpasses the comparator reference magnitude of voltage (fixing) of receiving terminal, comparator is output switching activity variation level switching signal, have or not when blocking detecting shoe cover, can be stronger because of transmitting, various impacts can be ignored the detection influential effect.Adopt this mode, there are the following problems: emission, reception optoelectronic switch can only be worked between fixing distance, and, its range error must be less than 5mm, when detecting the transparent plastic film shoe cover, because its change in detection signal amplitude is less, the height of the power of transmitting terminal signal, receiving terminal sensitivity will directly affect the reliability of detection, signal is strong, just penetrate, can't detect shoe cover, signal is weak, its amplitude of variation does not reach the comparator reference magnitude of voltage, can't detect shoe cover yet; In addition, infrared emission, receiving tube self are to the susceptibility (change of sensitivity such as summer and winter is larger) of environment temperature, detect the variation of distance, whether the infrared LED pipe has dust to block, alignment error, emission, receiving terminal aligns, to the factor such as inclined to one side, all can have a strong impact on the reliability of detection, so directly adopt the Photoelectric infrared switch of circuit common to be used for the detection mode of transparent plastic film shoe cover, reliability is low, can not adapt to the problem that external condition changes, and production requirement is high, the qualification rate of batch production only is about 20%.
The utility model content
The purpose of this utility model just provide a kind of detecting reliability high, and can significantly improve the transparent plastic film shoe cover and detect that performance, cost are low, the self adaptation transparent plastic film shoe cover photoelectric detection system of long service life.
For achieving the above object, the utility model comprises transmitting terminal and receiving terminal, be provided with the infrared signal transmitting tube in the transmitting terminal, be provided with the infrared signal receiving tube in the receiving terminal, also comprise single-chip microcomputer, OC gate circuit and output lead in the described receiving terminal, described single-chip microcomputer is connected with the infrared signal receiving tube by the PCB circuit board, and described OC gate circuit is connected with single-chip microcomputer, and described output lead is connected with the OC gate circuit; Described single-chip microcomputer adopts the SMD PIC12F675 single-chip microcomputer of octal.
The utility model can be realized automatic decision, and automatically adjust the detection mode of detection reference owing to adopted the SMD PIC12F675 single-chip microcomputer of the octal that is connected with receiving sensor, greatly improve the automatic adaptability of environmental change and the reliability of detection.When having shoe cover to block, single-chip microcomputer sampling A/D value increases, when blocking without shoe cover, single-chip microcomputer sampling A/D value diminishes, single-chip microcomputer is made detection reference with the A/D value when blocking, and can fast manually upgrade detection reference, to adapt to and to correct because the sudden change of environment for use temperature or newly installation and measuring distance change or install and adjust the in particular cases former detection reference value of depositing such as rear emission, reception skew, improve the reliability of detection.The utility model compared with prior art has following positive effect: 1, detection sensitivity is high: can realize the effective detection to light single-layer and transparent plastic foil (shoe cover); 2, detection range is wide: still can normally detect (if regulate emissive porwer, also can realize wider detection) in the scope of 15cm to 50cm; 3, adaptive environment changes: can regulate detection reference from motion tracking, with the temperature wide variation that conforms, and can effectively eliminate the impact of dust on detecting; 4, the difference of self adaptation transmitting terminal: the adaptability to emission, receiving sensitivity is very large, in relative broad range, uniformity to emissive porwer is not done requirement, need not the consistent transmitting terminal of match strength, during installation, also need not to be strict with emission, receiving terminal is aimed at and regulated, in addition, under the condition of transportation vibrations, when emission, receiving terminal generation skew, still can work.
