SYNOPSIS:
The Automatic poor quality rejecter sense and deliver the right product and ejects outs the poor quality products.
The product is moved to the Sensor Cabin to verify the quality through the Conveyor. The Dimension of the product is checked using the Sensor Interface. If the product has no accurate dimension the rejecter rejects the product to the Rejecter Bin. If the product has high quality the conveyor moves it to the Accepted Bin. The motor is used to move the Conveyor that carries the product. The Micro Controller is used to sense the product using sensor interface, control the rejecter using rejecter control, control the motor using motor driver. The Power Supply provides power to the all the parts of the systems
Micro controller A microcontroller (sometimes abbreviated µC, uC or MCU) is a small computer on a single integrated circuit containing a processor core, memory, and programmable input/output peripherals. Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.
Microcontrollers are used in automatically controlled products and devices, such as automobile engine control systems, implantable medical devices, remote controls, office machines, appliances, power tools, toys and other embedded systems. By reducing the size and cost compared to a design that uses a separate microprocessor, memory, and input/output devices, microcontrollers make it economical to digitally control even more devices and processes. Mixed signal microcontrollers are common, integrating analog components needed to control non-digital electronic systems.
Some microcontrollers may use four-bit words and operate at clock rate frequencies as low as 4 kHz, for low power consumption (single-digit milliwatts or microwatts). They will generally have the ability to retain functionality while waiting for an event such as a button press or other interrupt; power consumption while sleeping (CPU clock and most peripherals off) may be just nanowatts, making many of them well suited for long lasting battery applications. Other microcontrollers may serve performance-critical roles, where they may need to act more like a digital signal processor (DSP), with higher clock speeds and power consumption.
Motor Drive
A motor drive, in the field of photography, is a powered film transport mechanism. Historically, film loading, advancing, and rewinding were all manually driven functions. The desires of professional photographers for more efficient shooting, particularly in sports and wildlife photography, and the desires of amateur and novice photographers for easier to use cameras both drove the development of automatic film transport. Some early developments were made with clockwork drives, but most development in the field has been in the direction of electrically driven transport.
At first, motor drives were external units that attached to the basic camera body, normally beneath it, with an interface consisting of a physical drive socket and some electrical contacts to signal the drive when to actuate. Beginning in the late 1970s, motor drives began to be integrated into cameras themselves—at first, in compact cameras for the beginner market, and by the 1980s, in amateur-grade and later professional-grade single lens reflex cameras. By the 1990s, the vast majority of 35mm cameras had integral motor drive, and the feature found its way into some medium format cameras as well.
