WIRELESS TOUCH SCREEN BASED MULTI-MOTOR CONTROL SYSTEM WITH
FAULT-TOLERANT DESIGN BASED ON CAN BUS
ABSTRACT:
In this paper, a multi-motor control circuit based on controller
area network (CAN) bus is presented. The PIC16F877A microcontroller
is the foundation and the circuit which is based on the inbuilt
usage of analog-to-digital converter, in order to achieve the
breakdown of motor control. In the subdivision control, subdivision
steps are set by software. Article details the overall structure of
the system of hardware design, software design process, and CAN bus
controller structure. Compared with the traditional centralized
touch control, the multi-motor control system has higher
reliability. Experimental result shows that the system and the
intelligent control module is effective and efficient.PROJECT
DESCRIPTION:
The main aim of this project to control multi number of motors
using wireless based touch screen and CAN protocol. The motors are
connected and monitored through CAN bus controller for fast
controlling. The CAN protocol and analog to digital controller is
inbuilt in the PIC microcontroller. The motor can be controlled
through a touch screen and RF transmitter and receiver. The
touching data is transmitted through wireless transmitter and
received by the receiver in the motor side. The microcontroller
sends the information through CAN bus and the motor will be rotated
in the desired speed and desired direction. The motor condition is
monitored by using two various sensors. Tri-axial accelerometer is
for monitoring the motor vibrations. Thermocouple is to monitor the
heat produced from the coils. These sensor outputs are given to
microcontroller and transmitted to the control room for remote
monitoring purpose. In case of abnormal situations, the buzzer will
be activated for alert purpose. Also the motor will be tripped off
from the mains immediately, for safety.BLOCK DIAGRAM:CONTROLLING
