ABSTRACT

Title of the project: Automatic Conveyor for Industrial Automation The number of tags handled by the conveyor on the whole will be displayed

simultaneously along with regulating the speed of conveyor. This project will save the

power of motor operating the conveyor by regulating the conveyor automation, i.e.the conveyor actuates only when a tag is sensed.

This Automatic Conveyor for Industrial Automation consists of two object sensors, rpm

sensor, and rpm control circuit which controls the speed of the motor driving the

conveyor. The object sensors which detect the objects sends signal to the motor

driving circuit to on/off the motor.

Dynamic environments pose a challenge to the read performances of current

RPM control systems. Moving tags on a conveyor belt affect the read performance of

a static reader. Our project attempts to evaluate a static reader identifying moving

tags on a conveyor belt. We propose an algorithm enabling the conveyor belt to

dynamically adjust its speed according to the load automatically, also it reliably

identify tags without prior knowledge of how tags are distributed on the conveyor

belt. We show by simulations that our algorithm yields more than 99% of tags being

successfully identified, along with trying to maximize the average speed of the

conveyor belt. In addition, the algorithm can be applied for different reader's ranges.

The number of tags handled by the conveyor on the whole will be displayed

simultaneously along with regulating the speed of conveyor. This project will save the

power of motor operating the conveyor by regulating the conveyor automation, i.e.

the conveyor actuates only when a tag is sensed.

The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with

8K bytes of in-system programmable Flash memory. The device is manufacturedusing Atmel’s high-density nonvolatile memory technology and is compatible with the

industry-standard 80C51 instruction set and pin out. The on-chip Flash allows the

program memory to be reprogrammed in-system or by a conventional nonvolatile

memory programmer. By combining a versatile 8-bit CPU with in-system

programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful

microcontroller which provides a highly-flexible and cost-effective solution to many

embedded control applications.

This project uses regulated 5v, 500mA power supply. 7805 and 7812 three

terminal voltage regulators are used for voltage regulation. Bridge type full wave

rectifier is used to rectify the ac output of secondary of 230/12v step down

transformer.

Aim:In this project we have to control the conveyor automatically by sensing the

objects placed in the conveyor. Also, by using RPM sensor we have to control the
