Principle of work is as follows:
The energized K switch, power supply output 12V DC voltage is used for circuit at different levels.Power supply switch circuit 5 electric after, the duty of the T trigger that IC2 forms may be in reset mode, also may be in SM set mode.If be in reset mode, the output terminal 1 end output low level of IC2, the coil losing electricity of triode BG1 cutoff relay 1J, the normally closed node of 1J will be in closure state, often open node and be in off-state.Be connected on Drive and Control Circuit 3 on the normally closed node of 1J1 like this and will get electricly, and start working.Be connected on the Drive and Control Circuit 2 that 1J1 often opens on the node dead electricity is not worked, simultaneously, the coil that is connected on the electromagnet 13 on the normally closed node of 1J2 gets electric, makes clutch coupling 9 interlocks, is connected on the coil losing electricity that 1J2 often opens the magnet 14 on the node clutch coupling 10 is separated.Otherwise IC2 is in SM set mode, its output terminal 1 end will be exported high level, triode BG1 saturation conduction, and the coil of relay 1J gets, the normally closed node of 1J will disconnect, often open node with adhesive, thereby Drive and Control Circuit 3 quits work dead electricity, Drive and Control Circuit 2 will get electric and start working, while electromagnet 13 coil losing electricities, clutch coupling 9 separates, and electromagnet 14 coils get electric, clutch coupling 10 interlocks.Like this no matter which kind of state IC2 is in, always have-the road Drive and Control Circuit can start working, because of these two kinds of Drive and Control Circuit symmetry fully, thus following with Drive and Control Circuit 3 the electrician illustrates as example.
Drive and Control Circuit 3 electric after because the voltage at capacitor C 4 two ends can not suddenly change, power supply is added in 2,6 ends, one high level of IC5 by C4 like this, IC5 resets thereupon, its 3 end output low levels.Thereby the coil losing electricity of BG4 cutoff relay 2J, the node of often opening of 2J is in off-state like this, is connected on motor 1 dead electricity of often opening on the node, and stall, electromagnetic brake 26 is also braked dead electricity; All parts of mechanical part all are in stationary state, and picture band 24,25 will be in stationary state like this.Along with capacitor C 4 is constantly charged by resistance R 7 and adjustable potentiometer W1, the 2 pin voltages of IC5 are in continuous decline, when being lower than 1/3 promptly after 4 volts of working power 12V, its 3 ends output high level of IC5 set, the coil of relay 2J gets electric, and 2J often opens node with closure, is connected on 2J and often opens the civil power that motor 1 on the node and electromagnet controller 26 will obtain 220V, thereby electromagnetic brake 26 separates with shaft coupling 3, and motor 1 begins to rotate.And driving worm screw 5 passes through clutch coupling 9 through worm gear 7 reductions of speed, transmission shaft 15 is rotated, and by gear 17 meshing gears 19, make transmission shaft 21 also begin to rotate, make picture 24,25 by 4 poles 23 like this, picture 24,25 is scrolled up synchronously, drive transmission shaft 16,22 and synchronous backward rotation by the engagement between the gear 18,20.So just realized that the picture band 24,25 of reeling on 15,16,21,22 main shafts scrolls up synchronously.Because of clutch coupling 10 separates, worm gear 8, worm screw 6 and motor 2 do not rotate like this.In IC5 set, the base stage of BG2 is also because of obtaining the high level saturation conduction, and gives capacitor C 3 chargings by resistance R 5.Along with the rising of 3 terminal voltages of IC4, behind the cut-in voltage that reaches the IC4 gate circuit, 1 end of IC4 output high level so just makes this homophase gate delay of IC4 open.This time-delay is in order to make motor 1 starting, and drives picture 24,25 and scroll up, make unthreaded hole A or B or ... can leave between light source D10 and the phototriode BG3, phototriode BG3 is ended under the situation of light source not having.So just can make motor 1 not make high level give 2,6 ends of IC5 again, and make it to reset through BG3 in the moment of starting.Only add this time-delay in circuit, motor 1 could start, and picture 24,25 could normally roll.When picture 24 view pictures that roll show, unthreaded hole A or B or ... will be through between light source D10 and the phototriode BG3, BG3 conducting at this moment will be given 6 ends of IC5 the high level of 1 end of IC4 through BG3, and IC5 is resetted; 3 end output low levels, the coil losing electricity of triode BG4 cutoff relay 2J, 2J often opens node and will discharge disconnection.Be connected on 2J and often drive motor 1 on the node and electromagnetic brake 26 also with dead electricity, thus detent 26 brakings, and motor 1 is with quick stall.All mechanical drive all stop operating after running out of steam, and the view picture picture is with static and begin regularly to show that regularly timing can be adjusted timing by the manual adjustments of W1 by C4, R7 and potentiometer W1 decision to a few minutes in tens seconds like this.BG2 ends when IC5 resets, and capacitor C 3 waits for that by resistance R 6 discharge BG2 conducting next time charges for capacitor C 3 again.When picture begins regularly to show, timing circuit is work like this, after 6 ends of IC5 obtain high level, IC5 resets, capacitor C 4 is constantly charged by R7, W1, the 2 pin voltages of IC5 are in continuous decline, when be lower than the 12V working power 1/3 after, IC5 set, its 3 ends output high level, the coil of relay 2J gets, be connected on motor 1 and the electromagnetic controller 26 often opened on the node and will obtain the 220V civil power, detent 26 loses braking, and motor 1 begins to rotate, and drives advertisement poster and wear 24,25 and scroll up and show next width of cloth picture.And so forth, advertisement poster on main shaft 16 and 22 is worn and is all over, at this moment unthreaded hole a is through between light emitting diode D8 and the photodiode D1, make photodiode D1 see light and conducting, 1 end of IC1 will obtain high level through rejection gate, the 3 end output low levels of IC1 are owing to the both end voltage of capacitor C 1 can not be suddenlyd change, so 5 ends of IC1 also obtain a low level.So cause 6 end ground connection 5 ends, 6 ends are through rejection gate, 4 ends are exported high level, and are connected to 2 ends, make 3 ends of IC1 can keep output one low level.Because power supply will give capacitor C 1 charging by resistance R 2, and 5 terminal voltages are uprised by low, after 5 terminal voltages of IC1 reach the cut-in voltage of gate circuit, 4 ends will become low level.After D1 sees that photoconduction is logical, 4 ends of IC1 will be exported a monopulse like this.After input end 3 ends of IC2 are imported this pulse, to overturn output terminal 1 end of IC2 of T trigger will become high level, the BG1 saturation conduction, the coil of relay 1J will get, it often open node with closure, normally closed node will disconnect, thereby be connected on Drive and Control Circuit 3 dead electricity on the normally closed node of 1J1, and quit work, be connected on 1J1 often open Drive and Control Circuit 2 on the node electric, will start working, be connected on the electromagnet 14 that 1J2 often opens on the node simultaneously and will obtain civil power, and make clutch coupling 10 interlocks, be connected on electromagnet 13 dead electricity on the normally closed node of 1J2 and clutch coupling 9 is separated.
Drive and Control Circuit 2 must be established beginning work by cable, and principle is described with Drive and Control Circuit 3.Motor 2 work are rolled picture 24,25 synchronously downwards, and regularly show.Until on the transmission shaft 15 and 21 during the advertisement picture end of tape, unthreaded hole b will be through between light source D9 and the photodiode D2, make the D2 conducting, reset terminal 4 ends of IC2T trigger obtain high level after the D2 conducting, and IC2 is resetted, and its 1 end output low level, BG1 ends, relay 1J coil losing electricity, make its normally closed node closed again, often open node and disconnect, Drive and Control Circuit 3 is established beginning work again by cable like this, Drive and Control Circuit 2 dead electricity, simultaneously electromagnet 13 will get electric, clutch coupling 9 interlocks, electromagnet 14 dead electricity and clutch coupling 10 is separated, go round and begin again, two-sided advertisement picture will be realized regularly showing and back and forth rolling up and down synchronously.
When the curtain of night comes, the resistance of photoresistance R19 will increase to more than 10 megaohms, 6 ends of IC7 are through the dividing potential drop of resistance R 17, R18 and R19 like this, provide a voltage that is higher than 1/3 working power by R19, make IC7 be in reset mode, 3 end output low levels, export through the IC4 phase inverter, make triode BG8 saturation conduction, the coil of relay 4J gets electric, is connected the illuminating lamp of often opening on the node 28 and lights and make.When working at night, as the interference that meets stray light is when diminishing the resistance of photoresistance suddenly, owing to be connected to capacitor C 9 in the circuit, because of its both end voltage can not be suddenlyd change, and 6 terminal voltages of IC7 can not be suddenlyd change, and just can not cause frequent recovery and the set of IC7, illuminating lamp is when external interference like this, just can not be flickering, so the serviceable life of energy prolonging lamp tube.
