Design, Modeling and Application of Microcontroller (MCU) on MAIN ENGINE HIGH TEMP ALARM SYSTEM

Abstract

In  this  journal, the simulation  of  an  automatic  system  for the safety of the main engine is developed. M/E jacket water temperature and M/E L.O temperature sensors are used to automatically stop the engine in case of high temperature. The high values of temperature can cause a severe damage to the engine. An important feature of this automation process is to minimize the human errors by not to relying on humans as  operator  for  machinery,  and  to  improve  working  and  performance  of the system .  The system  in  this  paper  used  the  microcontroller  PIC18F4550  as  the  central control  unit,  LM35 as temperature  sensors ,liquid crystal  display  (LCD)  as  indicator  to  display  the  different  system  working status an addition to some of drivers, relay and light emitting diodes  (LED) as  indicators  to  display  the  corresponding  working  appliance  driver.  The implementation  and  simulation  of  the  system  work  has  been  achieved  by using  proteus  ISIS professional  software  v7.6  and  PIC C Compiler for software to  write the  equivalent program  and  generate .hex  file  for  system working.
