(5), embodiment

Accompanying drawing has provided an embodiment of the present utility model.

Referring to Fig. 2.In this example, the electric bridge D1-D4 IN4001 of bridge rectifier circuit, mu balanced circuit 7805 integrated circuit, capacitor C 1:470 μ 25v; C2:100 μ, 16v; C3:10 μ; C4:30p; C5:30p.A is one-chip computer module AT89C2051, and 15-19 is its output pin, is connected with G, F, E, D, the C of the touch kinematic train circuit of cylinder roller bearing respectively, and 6M is the time oscillatory circuit.

Referring to Fig. 3.Among the figure, bridge rectifier circuit D1-D4:IN4148; C1-C2:3.3 μ; R1-R2:22K; T1-T2:C945; Relay J 1-J2:4123.A, the B voltage for being drawn through C, E and D, F, the G of cylinder roller bearing kinematic train circuit by the single-chip microcomputer output pin is generally 2.5～5.0V.P is the metallic bond of rotatable 360 degree, prevents the lead knotting.

Referring to Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8.

L, M, N are sheet metal among Fig. 4.

Among Fig. 5, the direction of arrow indication is a direction of current.

Among Fig. 6, the 1,2,3,4,5, the 6th, thin scale copper exposed parts.The material of A, B, C, D, E, F, G is fixed on respectively on the roller bearing successively for the insulation thin copper wire, mutually insulated each other, and being connected with one in tap place can hang the metallic bond P that revolves three-sixth turn, and the thin copper wire that prevents to insulate is tied a knot.

Among Fig. 7, L1-L3, M1-M3, N is respectively scale copper, is fixed on the back side of advertisement drawing paper.

Among Fig. 8,7. being advertisement slip roller bearing, 8. is belt, 9. is wheel disc, 10. is that mobile instrument slides really, and is the mobile instrument slip roller bearing that connects lead.

When advertisement screen rolled, L1 overlapped with L, and N does not overlap, and M overlaps with M1, and lead C, A, E are high level at this moment.When just changeing, C is high level all the time, and C line and A line join, and the E line joins with

thin scale copper

1,2, and lead D, B, F must be low level.In the moment of just changeing, the F lead sports high level, joins with

thin scale copper

5,6, in case M overlaps with M1, F, B, D lead become high level, and screen is static.When the F lead after official hour (as 0.2 second) has become high level suddenly, the L1 on the static screen has left L, M1 has left M, screen moves on just changeing.In case M overlaps with M2, screen is static again, and L also overlaps with L1.As the motor counter-rotating, lead C, A are always low level at this moment, and the D line is always high level.Suppose screen at that time at the 3rd width of cloth picture, the E line became low level suddenly by high level when screen moved down, and the M3 in the screen overlaps with M.L overlaps with L3.Because the E line has become low level, L3 has left L, and the moment E line that leaves has become high level again.The advertisement picture that moves has been got back to second width of cloth picture again.

The rotating speed of motor and power control can be adopted three kinds of modes, promptly reduce voltage, reduce and sharpen magnetic, increase resistance.It is very accurate that the use of relay can make the timing of screen rotate.J1, J2 relay be not because of using normally closed contact when switching on or stop the advertisement screen running, and the damping that causes during short circuit is equivalent to clamping device.By starting high-low level may command J1, the J2 adhesive in the running of running, discharge when shutting down, straight stable when guaranteeing the running of advertisement screen picture, picture is not loosening when shutting down.

If in the time of in the middle of picture forwards certain two width of cloth picture to; sudden power; single-chip microcomputer will be carried out the software program of original state; the i.e. software program of first width of cloth picture; the N contact chip communicates with the G line; finish the time stack that does not have working procedure, play the effect of protection circuit, split by the motor tearing to prevent screen.
