Original state S, wherein original state S are that cigarette packet to be measured enters the last one moment before photodetector.
Voltage acquisition module 1302 is used for since original state S, is N in the umber of pulse of incremental shaft encoder outputi
When, obtain the detectable voltage signals v of photodetector outputi, wherein 1≤i≤m, m are in the conveying direction by cigarette Bao Jun to be measured
Total hop count of even division.

Packet i-th section when, photodetector blocks height x by cigarette packet shield portions to be measuredi。
Optionally, height determining module 1303 is blocked for according to detectable voltage signals viWith photodetector in initial shape

For example, blocking height determining module 1303 using formula xi=(1-vi/ Z) H calculating block height xi, wherein H is light
The length of the working region of electric explorer in the vertical direction.
Deformation identification module 1304 will block height xiWith corresponding calibrated altitude XiIt is compared, to judge cigarette to be measured
Whether i-th section of packet deforms upon.
Qualified judgment module 1305 is used for according to the hop count deformed upon in cigarette packet to be measured, to judge whether cigarette packet to be measured closes
Lattice.
Optionally, deformation identification module 1304 is specifically blocking height xiWith corresponding calibrated altitude XiAbsolute value it is big
When predetermined threshold, judge that i-th section of cigarette packet to be measured deforms upon.
For example, setting β to indicate the predetermined threshold of height fluctuation.
If 1) │ xi-Xi│≤β then shows that i-th section of the cigarette packet does not deform upon, can enable ei=0.
If 2) │ xi-Xi│ ＞ β then show that deformation has occurred in i-th section of the cigarette packet.
In addition, deformation identification module 1304 is additionally operable to after judge cigarette packet to be measured i-th section deforms upon, if blocking height
xiMore than corresponding calibrated altitude Xi, judge that upward deformation has occurred in i-th section of cigarette packet to be measured；If blocking height xiLess than phase

The hop count that downward deformation occurs in cigarette packet to be measured counts downward deformation ratio, counts total according to the hop count deformed upon in cigarette packet to be measured
Deformation ratio, if upwards deformation ratio be more than make a reservation for upward deformation ratio thresholding, downward deformation ratio be more than make a reservation for downward deformation ratio thresholding or
The total deformation ratio of person, which is more than, makes a reservation for total deformation ratio, then judges that cigarette packet to be measured is unqualified.
For example, according to above-mentioned analysis, matrix e=[e1, e2, e3 ... ..., em] can be obtained.
If 1 number is f in matrix e, -1 number is g, then：
The upward deformation ratio w1=f/m of cigarette packet；
The downward deformation ratio w2=g/m of cigarette packet；
Total deformation ratio w3=(the f+g)/m of cigarette packet.
If h1 is the upward deformation ratio maximum permissible value of cigarette packet, h2 is the downward deformation ratio maximum permissible value of cigarette packet, and h3 is cigarette packet
Total deformation ratio maximum permissible value.The size principle of these three values is：It can guarantee that underproof cigarette coating detects, and be not in
Flase drop.
As w1 ＞ h1, w2 ＞ h2 or w3 ＞ h3, judge that the cigarette packet is unqualified, it is on the contrary then judge cigarette include lattice.
Above-mentioned formula x is given belowi=(1-vi/ Z) H specific derivation process：
If the light quantity sent out on 41 unit area of transmitting terminal of photoelectric detector 4 is K.
(1) when in photoelectric detector 4 without any object
The area of rectangle ABCD is GH, then the light summation that transmitting terminal 41 is sent out is GHK, total light that then receiving terminal 42 receives
Amount is GHK.
Assuming that the voltage signal size of photoelectric detector 4 is Z, the then corresponding electricity of light of 42 units of light of receiving terminal at this time
Pressure is Z/ (GHK).
(2) when there is cigarette packet in photoelectric detector 4
Rectangle ABEF is not blocked, and rectangle EFCD is blocked completely by cigarette packet abcd.The height of rectangle ABEF is I, rectangle

H=I+x is 1.
The area of rectangle ABEF is GI, and the light quantity which emits beam is GIK, which will all arrive at and connect
Receiving end, i.e., the light quantity that ABEF receiving terminals receive are GIK.
Rectangle EFCD transmitting terminals emit beam and are all blocked by cigarette packet abcd, therefore the light quantity that EFCD receiving terminals receive is
0.Then the light quantity that rectangle ABCD is received is equal to the light quantity that rectangle ABEF is received, i.e. GIK.
Assuming that the voltage signal size of detector 4 is v at this time, v is directly proportional to the light quantity GIK that receiving terminal ABCD is received, again
Since the corresponding voltage of the light of receiving terminal units of light is Z/ (GHK), then：

Phase angle be α, the radius of driving wheel 3 is R, and the arc length of P1 to P2 is LP, and the length of Q1 to Q2 is LQ, is then obtained：
Phase angle
When not having skidded failure between driving wheel 3 and belt 2, the linear velocity of driving wheel 3 and belt 2 is identical
, then the length LQ of the arc length LP and Q1 to Q2 of P1 to P2 is identical, i.e.,：
Operation of the cigarette packet 1 on belt 2 is driven by the frictional force between cigarette packet 1 and belt 2, in cigarette packet 1 and belt 2
When not having skidded failure, cigarette packet 1 and belt 2 are relatively stationary, i.e., cigarette packet 1 run distance and belt 2 run away from
It is identical from LQ, it is assumed that the distance that cigarette packet 1 is run in the process is L, and the calculation formula for then obtaining L is：
Formula 4. in parameters meaning：

(1) from during state S to U, 1 range ability of cigarette packet is L, and shaft encoder 5 exports NiA pulse signal.
As can be seen from Figure 14：
L=iG is 5.
It is 4. obtained by formula：
(2) from during state S to Y, 1 range ability of cigarette packet is L ＇, and shaft encoder 5 exports M pulse signal.
As can be seen from Figure 14：
L '=(m+1) G is 7.
It is 4. obtained by formula：
5. 6. 7. 8. aggregative formula：
It solves：
Formula 9. in parameters meaning：
Ni--- since cigarette packet 1 will go into photoelectric detector 4 (state S), until i-th section of cigarette packet 1 is examined by photoelectricity
It surveys device 4 and detects (state U), the pulse number that incremental shaft encoder 5 exports during being somebody's turn to do；

M --- m=J/G, J is the length of normal cigarette packet 1, and G is the width of photoelectric detector 4.
From formula 9. it is concluded that：Since cigarette packet 1 will go into photoelectric detector 4 (state S), when
When the pulse number Ni that incremental shaft encoder 5 exports is equal to iM/ (m+1), i-th section of cigarette packet 1 is detected by photoelectric detector 5
It arrives.

Optionally, according to detectable voltage signals viThe ratio of the voltage signal Z exported at original state S with photodetector
Height x is blocked in value determinationi。
For example, using formula xi=(1-vi/ Z) H calculating block height xi, wherein H is the working region of photodetector
Length in the vertical direction.
Step 1604, height x will be blockediWith corresponding calibrated altitude XiIt is compared, to judge the i-th of cigarette packet to be measured
Whether section deforms upon.
Wherein, if blocking height xiWith corresponding calibrated altitude XiAbsolute value be more than predetermined threshold, then judge cigarette to be measured
I-th section of packet deforms upon.
After judge cigarette packet to be measured i-th section deforms upon, still further comprise：
Blocking height xiMore than corresponding calibrated altitude XiIn the case of, judge i-th section of cigarette packet to be measured have occurred to
Upper deformation；Blocking height xiLess than corresponding calibrated altitude XiIn the case of, judge i-th section of cigarette packet to be measured have occurred to
