Description

Cigarette quality testing device

Technical field

The present invention relates to a kind of cigarette and prop up, relate in particular to a kind of cigarette quality testing device.

Background technology

Cigarette quality detects and comprises bear, dilutability, the detection of OTIS external form and the rejecting that defective cigarette props up that cigarette is propped up; Occur in propping up with the tobacco product of avoiding producing that the empty pine in end, gas leakage, the excessive or too small cigarette of resistance to suction prop up, obbbin and yew paper alice when cigarette props up cigarette, guarantee the quality of the tobacco product of production.

Cigarette quality in the tradition detects and adopts mimic channel that the sensor signal of bear, dilutability, OTIS external form is carried out the Signal Processing differentiation, props up defective cigarette with the identification cigarette and props up.Processing mode is simple, adapts to the site environment ability in the actual production process, and the influence that aging, the pressure variation of sensor etc. brings can not be adjusted automatically, has mistake, leaks the situation of picking.

Prior art to the detection principle of dilutability, bear, OTIS external form respectively like Fig. 1, Fig. 2, shown in Figure 3: the signal of negative pressure transducer, bear and the OTIS external form photoelectric sensor at dilutability T1, T2 station is distinguished the defective that cigarette props up through relatively differentiating of preposition amplification and mimic channel; Because mimic channel is to the variation at scene; The crest that causes like the variation of mechanical location, the detection of wave trough position voltage; Sensor is aging and the installation site changes, negative pressure signal changes and can not well adapt to, and can have erroneous judgement, a situation of failing to judge.

Summary of the invention

The technical issues that need to address of the present invention have provided a kind of cigarette quality testing device, are intended to solve the above problems.

In order to solve the problems of the technologies described above, the present invention realizes through following technology side:

The present invention includes: second negative pressure transducer that first negative pressure transducer that dilutability detects, dilutability detect; Described first negative pressure transducer links to each other with the second preposition amplification with the first preposition amplification that dilutability detects respectively with second negative pressure transducer; Bear's sensor and a nominal preposition amplification that links to each other with nominal sensor; Photosensitive sensor and the preposition amplification of OTIS external form that links to each other with photosensitive sensor; Also comprise: an A/D module; One end of described A/D module links to each other with the second preposition amplification, the preposition amplification of the preposition amplification OTIS external form of bear with the first preposition amplification that dilutability detects respectively; The other end of A/D module links to each other with single-chip microcomputer; Single-chip microcomputer connects driver module.

Compared with prior art; The invention has the beneficial effects as follows: owing to adopted high performance single-chip microcomputer; In the Signal Processing process, realized with hard function of soft generation; Simplify the hardware components of system, improved the reliability of system and can safeguard row, made the accuracy of detection of system be further improved.

Embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

Visible by Fig. 4, Fig. 5, Fig. 6: as to the present invention includes: second negative pressure transducer that first negative pressure transducer that dilutability detects, dilutability detect; Described first negative pressure transducer links to each other with the second preposition amplification with the first preposition amplification that dilutability detects respectively with second negative pressure transducer; Bear's sensor and a nominal preposition amplification that links to each other with nominal sensor; Photosensitive sensor and the preposition amplification of OTIS external form that links to each other with photosensitive sensor; Also comprise: an A/D module; One end of described A/D module links to each other with the second preposition amplification, the preposition amplification of the preposition amplification OTIS external form of bear with the first preposition amplification that dilutability detects respectively; The other end of A/D module links to each other with single-chip microcomputer; Single-chip microcomputer connects driver module;

Described single-chip microcomputer comprises a digital filtering module, a fixed threshold, a unsteady thresholding.

The present invention is an acp chip with 16 single-chip microcomputer XC167, sends into XC167 to sensor through the information of preposition amplification through A/D, with soft generation firmly according to the variation of on-the-spot actual capabilities, through model information is carried out overall treatment, reach good effect.

Aspect software processes; With the crest of signal in continuous high speed production, the centre of area of trough is the detection position of crest, trough; Realize automatic detection and localization; Replace original position clock signal detection and localization mode, eliminated because the sensor of clock signal and the influence of variation to detecting of detecting sensor installation site are provided.Simultaneously, loaded down with trivial details position installation, debugging, school odd-job work have been eliminated.

With the area processing mode system is strengthened greatly to on-the-spot anti-jamming capacity.

On juggling, introduce the difference thresholding determine mechanism that floats, the influence that eliminated that former simulation circuit is aging to photoelectricity and negative pressure transducer, negative pressure fluctuation and other site environment brings.
