When circuit access power supply, reset switch 4 is allocated to after enable position, emergency button 3 is placed in normal position, the power supply of 220V is transformed into the alternating current of 9V through transformer 15, through the rectification of diode D1, D2, D3, D4, a road obtains zero cross signal pulse through zero cross detection circuit 12, delivers to the INT0 mouth of single-chip microcomputer 18U2, process through single-chip microcomputer 18U2, output drives signal with the speed governing of synchronized, one tunnel is through the filtering noise reduction of electric capacity E1 and C1, pass through again regulator block U1 and electric capacity E2, C2, obtain 5V direct current stably, circuit is powered, make the light emitting diode DS1 of power indicating circuit 13 obtain electric lighting by resistance R 1, single-chip microcomputer 18U2 follow procedure instruction works, pin 9 output low levels of single-chip microcomputer 18U2, by the base stage of resistance R 10 to triode Q2, make the conducting in the triode Q2 of switch working state, relay J 1 coil obtains electric, normally opened contact closure, form self-locking with the reset contact of reset switch 4, holding circuit continuous firing, be low level because single-chip microcomputer 18U2 pin 12 is drop-down, make optocoupler U5 work by resistance R 19, after 13 seconds of High Rotation Speed of material casting motor M, single-chip microcomputer 18U2 raises distance data command after treatment according to the throwing that input circuit 2 detects is set, determine the waveform that single-chip microcomputer 18U2 pin 12 is exported, make material casting motor M 1 by the rotating speed rotation of specifying, the pin 11 of single-chip microcomputer 18U2 is output as high level, therefore resistance R 15, light emitting diode DS2, optocoupler U4 do not work, not conducting of controllable silicon Q4, blanking motor M 2 is not worked, it is not luminous that light emitting diode DS2 does not have electric current to pass through yet, single-chip microcomputer 18U2 reads the information of meter re-detection circuit 11 simultaneously, obtain the initial value that feeder material is heavy, inner beginning timing, makes pin 11 become low level after 15 seconds, by resistance R 15, make optocoupler U4 work, light emitting diode DS2 is luminous simultaneously, bidirectional triode thyristor Q4 conducting, and blanking motor M 2 is rotated, single-chip microcomputer 18U2 is in the time entering work, with regard to endless reading, input arranges the set inventory of circuit 2, throwing is raised distance, shed the data of time and dead time, by data are processed, obtain respectively inventory, throw raise distance, shed time and dead time, the moment of blanking motor M 2 before opening and closing, read in respectively the time of shedding and dead time in real time, and carry out subtracting 1 countdown counting with each second, in the time that the time countdown of shedding equals 0, send into the dead time, the pin 11 of single-chip microcomputer 18U2 is exported high level, close blanking motor M 2, in the time that the dead time, countdown equaled 0, send into the time of shedding, the pin 11 of single-chip microcomputer 18U2 is drop-down is low level, open blanking motor M 2, so iterative cycles, until the feed variable quantity detecting is while being equal to or less than the inventory of setting, the pin 11 of single-chip microcomputer 18U2 is exported high level, close blanking motor M 2, time delay 10 or tens of second again, the pin 9 of single-chip microcomputer 18U2 is exported high level, relay J 1 power-off, normally opened contact is opened, 1 stall of material casting motor M, whole controller power-off, end once feeds intake.

In the course of the work, the single-chip microcomputer 18U2 moment is read inventory, throwing is raised distance, shed time, dead time, the material tuple certificate of meter re-detection circuit 11 and the pulse signal of zero cross detection circuit 12; Single-chip microcomputer 18U2, according to the material tuple certificate detecting, with the first heavy data operation of expecting of start, obtains the variable quantity of feed, and in the time that the variable quantity of feed is equal to or less than set inventory, single-chip microcomputer 18U2 closes blanking motor M 2 immediately; Single-chip microcomputer 18U2 is according to the zero-crossing pulse signal detecting, with synchronized output speed regulating control signal; Raise apart from changing if thrown, using reading numerical value after treatment as the new steering order of controlling material casting motor M 1 rotating speed, change its rotating speed; If read numerical value after treatment and be the instruction of shutdown, single-chip microcomputer 18U2 closes blanking motor M 2 immediately, and subtracts counting down of 1 second with what start in " 10 " or tens of second, is 0 o'clock complete machine powered-down, i.e. material casting motor M 1 time delay 10 or close after tens of second; Be often to open instruction if read numerical value after treatment, detect the feed variable quantity obtaining not as the instruction of shutdown, the pin 9 of single-chip microcomputer 18U2 is always drop-down is low level, now only has deenergization, or is threaded to off-position, just can close.

In the time adopting external control device to control, reset switch 4 is placed in to outer controlled position and inventory knob scale is placed in normally open position.

When controller of the present invention is because of unpredictable former thereby while causing fault, as long as emergency button 3 is placed in to emergency position, material casting motor M 1 and blanking motor M 2 are worked, carry out continuous bait throwing in.
