1. Distributed Remote Temperature Monitoring and Acquisition
System Based on CAN Bus
Abstract:
Embedded system comprises of both hardware and software. An embedded
system is a special-purpose computer system designed to perform a dedicated function.
Since the system is dedicated to specific tasks, design engineers can optimize it, reducing
the size and cost of the product.
In modem industrial and agricultural production, the working temperature change
reflects the operating status of equipments and change of many physical characteristics,
so the temperature is an important parameter, which needs to be monitored, especially in
the severe environment. So it is the most effective and most economical means of
equipment safety monitoring. A temperature remote monitoring embedded system
platform is designed in the paper.
Existing System:
In earlier system, temperature monitoring process is done and controlled by
human only. It will take more time and manpower for continuous monitoring, so we are
pulled to make an advanced new system.
Proposed System:
In our new system we will use CAN (Controller Area Network) and PIC
controller. Using UART communication we will interface PIC controller and PC. In this
project we can monitor and control the temperature via web.
