Grid, the grid of the second metal-oxide-semiconductor N2, the grid of third metal-oxide-semiconductor N3 and the 4th metal-oxide-semiconductor N4 grid pass through logic translator respectively
U2 is connected with microcontroller a, and is provided with one on each power motor M1 (or M2) and is connected with microcontroller a for detecting
The Hall sensor U3 of the turnning circle of power motor M1 (or M2).
Carry out the regulation of revolving speed and positive and negative rotation to power motor M1 (or M2) using motor control circuit as a result,
The moving direction to more picture background coiled materials 40 and mobile speed are realized by the control of revolving speed and positive and negative rotation to spool set 231
The regulation of degree, specifically: when microcontroller a is to P2A1 mouth input low level, the P2A2 mouthfuls of input high levels of logic translator U2
When, the Y1 and Y2 of logic translator U2 exports low level, the first metal-oxide-semiconductor N1 conducting and the second metal-oxide-semiconductor N2 cut-off, Y3 and Y4 output
High level, third metal-oxide-semiconductor N3 and cut-off the 4th metal-oxide-semiconductor N4 conducting, at this point, power motor M1 is rotated forward (conversely, then inverting, power
Motor M2 is also based on similarly).And the turnning circle of power motor M1 (or M2) then can be acquired respectively simultaneously using Hall sensor U3
Corresponding data is passed in microcontroller a, corresponding revolving speed is calculated by scheduled program by microcontroller a, when revolving speed mistake
Gao Shi, microcontroller a are to the P2A1 and P2A2 while input low level of logic translator U2, and stream out of power passes through power motor at this time
M1 declines its revolving speed；Conversely, then with aforementioned level relationship, power motor M1 is driven to carry out rotating forward or anti-when revolving speed is too low
Turn and increase revolving speed, to achieve the purpose that control revolving speed.
Preferably, optical detection device can be used in the picture detection device of the present embodiment, it may be assumed that as shown in figure 9, its
To be arranged in the left side side of more picture background coiled materials 40 and/or the phototriode D1 of the right side, and check bit 41 is then to open up
In the gap structure of the sides adjacent on the edge of more picture background coiled materials 40 and positioned at picture detection piece 41；Wherein, switch detection

It hinders between R3, emitter connects the emitter of phototriode D1 and the emitter of the second triode Q2, the second triode simultaneously
The collector of Q2 is connected with microcontroller a.
The specific location of check bit 41 can be detected by detection light Strength Changes using phototriode D1 as a result,
For on every width picture that check bit 41 is located at more picture background coiled materials 40, when this picture background is completely moved to photography
The after-frame mouth of canopy 10 and when forming wall, 41 position of check bit is just corresponding with the position of phototriode D1, this
When phototriode D1 can detect stronger light, phototriode D1 conducting, by first capacitor C2 the one or three pole
The base stage of pipe Q1 is dragged down by high level, and the second triode Q2 is dragged down the base stage of the first triode Q1 by high level, thus
Low level signal is exported to microcontroller a, stops moving so that microcontroller a can control electric reel according to this signal
Make.Conversely, the edge of more picture background coiled materials 40 then can be to light when the position where the deviation of check bit 41 phototriode D1
Electric triode D1 is blocked, so that light luminance detected by phototriode D1 is weaker, finally makes microcontroller with this
