Title Software Design of Family Fire Detection and Alarm System
Abstract
With the development of computer technology, communication technology and control technology, field bus technology appeared. Field bus technology promotes the development of the instrument, measurement and control system. As a field bus, CAN bus has characteristics such as fine stability, high reliability, quicker communication rate and low cost, and it can effectively support real-time, distributed control, thus it has been applied in many fields, and has a broad prospect for development. This subject designs a kind of fire alarm system, which adopts CAN bus technology. It is utilized for Family fire detection and alarm system.
In the environment of KEIL C51, using the modular design approach, this paper completed all modules: the communication module and digital filter module based on C8051F040. Through the arrangement of all the tasks, this paper achieved the requirement of this system.
The paper summed up the done work, has made the forecast to the intelligent fire alarm system development, and proposed some methods to improve system.
