Drawings
FIG. 1 is a schematic structural diagram of a metal part counting and monitoring system, wherein 1 is a metal part, 2 is a Hall switch, 3 is a bar magnet, and 4 is a conveyor belt;
FIG. 2 is a circuit diagram of a metal count monitoring system.
Detailed Description
The button SW1 is pressed, the P3.1 of STC89C51 singlechip outputs the high level, triode Q2 switches on, and solid state relay SSR input is electrified, and direct current MOTOR MOTOR begins to rotate, and the conveyer belt begins to convey the metalwork article of waiting to count the control, and DN6487 hall switch begins to detect the quantity of goods, and entire system begins work. When the metal piece gradually approaches the hall switch, the 3 pin of DN6487 changes from high level to low level, and after passing through the R1 and C1 accelerating circuits, the triode Q1 is turned off, and at this time, the P3.0 port is high level, indicating that the metal piece starts to count; when the metal piece is far away from the hall switch, the 3 pin of DN6487 is changed from low level to high level again, and after passing through the R1 and C1 accelerating circuits, the triode Q1 is turned on, and at this time, the P3.0 port is low level, which indicates that the counting operation of one metal piece is completed, and the data can be displayed in real time through the LCD 1602. If the key SW1 is turned off, the triode Q2 is turned off, the input end of the solid state relay SSR is powered off, the MOTOR MOTOR stops rotating, the conveyor belt stops working, and the counting process stops.
